DETAILED DESCRIPTION OF THE EMBODIMENTS

(8) As shown in FIGS. 1-7, a stirring canister lid adapted to different paint bucket openings comprises a paint outlet mechanism 1 for controlling a paint to be poured out, and at least two pressing mechanisms 2 for pressing a paint bucket and the canister lid, wherein for each pressing mechanism, the canister lid is provided with a through hole 21; a pressing lever 22 penetrates through the through hole; a seal sleeve 23 is sleeved outside the pressing lever 22; a turnup 231 of the seal sleeve 23 is pressed against the canister lid 3; a compressed spring 25 is sleeved at the outer periphery of the pressing lever 22 between the turnup 231 of the seal sleeve 23 and a handle 24 at an upper end of the pressing lever 22; a presser foot 26 is provided at a lower end of the pressing lever 22, characterized in that the presser foot surface is sector-ring-shaped, and is provided with a vertical surface 261 along a connecting line between two arc lines in the shape of section rings; and the vertical surface 261 divides the sector-ring surface into two presser foot surfaces with different heights and in a stepped manner, that is, a first presser foot surface 262 and a second presser foot surface 263.

(9) With this design, using multiple pressing surfaces, one same presser foot can be used to press paint buckets with different paint bucket opening thicknesses, unlike the prior art in which one presser foot can only be used to press paint buckets with the same bucket opening thickness. This configuration adopts the presser foot with a two-segment structure, which can be adapted to paint buckets with different clamping heights, improve the universality. The presser foot with the new structure is specially designed with two working surfaces with different heights, and the upper and lower working surfaces are spaced from the fitting surface of the seal right by different heights. This leads to an advantage that it can be adapted to paint buckets with different clamping heights from different customers. When the clamping height of the paint bucket of the customer is less than 7 mm, the upper plane can used to fit to and seal the paint bucket. When the clamping height of the paint bucket of the customer is more than 7 mm and less than 12 mm, the lower plane is used to fit to and seal the paint bucket. Designing the presser feet of the canister lid into presser feet with different heights and different specifications can achieve compatibility.

(10) The handle at the upper end of the pressing lever is a cam lifting handle 241 formed by hinging the upper end of the pressing lever and a cam; a cam surface 242 of the cam lifting handle 241 is in contact with an upper surface of a cam seat; the cam seat is a movable pipe sleeve 243 sleeved outside the pressing lever; an upper surface 244 of the movable pipe sleeve 243 is in contact with the cam surface 242 of the cam lifting handle; the movable pipe sleeve 243 is provided with a turnup 2431; and the upper end of the pressing spring 25 abuts against the turnup 2431 of the movable pipe sleeve 243.

(11) In the prior art, when the lid is compressed, the knob also needs to be pressed and rotated to ensure the presser foot is clamped on the paint bucket. Often, to ensure the sealing performance of the banister lid, the compressed spring of the knob is designed to have great elasticity. When the knob is rotated, the compressed spring needs to be pressed continuously. This can generate a very large counteracting force on the finger. The hand is squeezed and the operation is strenuous, and a person feels very uncomfortable in the case of repeated installation. As the cam lifting handle is adopted, when the spring is pressed, a long shaft of the cam lifting hand is in contact with the upper surface of the cam seat; at that time, the cam lifting handle is horizontally rotated, so that the presser foot presses against the paint bucket opening. FIG. 6 is an isometric sectional structure diagram of a first presser surface pressing against a paint bucket opening. FIG. 7 is an isometric sectional structure diagram of a second presser surface pressing against a paint bucket opening. In the entire horizontal rotation process, the hand only needs to hold the handle part to avoid return of the cam, so that the compressed spring is pressed continuously, and the working pressure of the finger is reduced, thereby saving physical work and facilitating operation. In FIG. 7, the paint bucket and the canister lid are in a sealed state, but are not shown in FIG. 7.

(12) A bracket 27 is provided correspondingly above the through hole 21 of the canister lid 3; an upper flat plate of the bracket 27 is provided with a bracket through hole 271; the movable pipe sleeve 243 is placed in the bracket through hole 271; and the movable pipe sleeve 243 and the bracket through hole 271 are in sliding fit to each other. As such, the whole pressing mechanism is supported by the upper through hole and the lower through hole, and is relatively firm. A reset spring 28 is sleeved at the outer periphery of the pressing lever between the lower side of the canister lid and the presser foot. With this design, the pressing mechanism can be prevented from moving when the presser foot is in a relaxed state. There are two or four pressing mechanisms.

(13) At least three clamping jaws 29 are provided at the periphery of the canister lid. There are three or four clamping jaws 29.

(14) When the canister lid is mounted on the paint bucket 301, firstly it needs to manually adjust the canister lid to be concentric to the paint bucket with visual inspection, to ensure the canister lid is mounted in place without offset; otherwise, a leakage event may occur. At least three clamping jaws 29 are provided at the periphery of the canister lid. When the stirring canister lid works, the plurality of clamping jaws surround the outer side of the paint bucket, and the canister lid can be adjusted to be concentric to the paint bucket. Four clamping jaws are added to the new structure of the canister lid. When the canister lid is sleeved on the paint bucket, center adjustment can be achieved to ensure the canister lid is centered, without manually adjusting the position of the canister lid to be centered, wherein four clamping jaws with the same size are uniformly distributed around the canister lid; and when canister lid is sleeved on the paint bucket, the four clamping jaws can be automatically pressed uniformly into a groove according to the outer diameter of the paint bucket, to ensure the canister lid is sleeved in a centered manner.

(15) The separation of the knob rotating and knob pressing operations is achieved as follows:

(16) The canister lid adopts a novel sealing structure suitable for a paint container and a canister lid, and comprises lid body in sealed connection with the container, and a knob, springs, a presser foot, a seal ring and the like for cooperative operation of an upper and a lower surface of the lid body. First, the lid body is provided with a special structure for installing the seal ring, the compressed spring and a locking support. With this structure, the three workpieces can be assembled and connected from bottom to top, and the compressed spring can bidirectionally tighten the seal ring at the lower end and the locking support at the upper end. Then, the double-segment presser foot and the reset spring are mounted at the lower end of the lid body. The two workpieces penetrate through the lid body and the afore-mentioned seal ring. The spring and other parts are connected to the knob at the upper end of the lid body. By rotating the knob, the presser foot is rotated, and contraction of the presser foot is controlled. After the presser foot rotates in place, a knob pressing platform is pressed down, and by using the cam lifting handle on the knob, the compressed spring and the locking support, the presser foot is lifted up, so that the seal ring and a lower edge 30 of a boss of the paint bucket opening completely fit to each other to achieve a sealing effect. To change the paint bucket, first, the knob pressing platform is lifted up, the presser foot is pushed out by using the reset spring between the presser foot and the lid body, and then the cam lifting handle is rotated in a reversed direction to contract the presser foot, and the paint bucket can be changed.

(17) The utility model achieves automatic centering in canister lid product installation, and achieves separation of pressing and rotating operations in the canister installation. The operation is easy and quick.

(18) The present application is specially directed to the newest universal canister lid of the company. The new structure can adapt to paint buckets of most brands in the market, does not need secondary processing or adjustment and is highly universal. Moreover, the canister lid is simple to operate and good in operation handfeel, and eliminates the shortcoming that the hand is squeezed during pressing and rotating operations of the previous canister lids.
