Toolbox group connecting structure

Abstract

A toolbox group connecting structure includes a connecting device and a snap-fitting device. The connecting device and the snap-fitting device are respectively installed on two adjacent toolboxes, and the two adjacent toolboxes are inserted to mate through the connecting device and the snap-fitting device, a plurality of toolboxes together form a trolley tool cart. By combining the plurality of toolboxes into the trolley tool cart that can be easily moved, the connection between the toolboxes constitutes an independent connection, thus making classification clear and not affecting each other. Therefore, it is possible to take and put down one toolbox in any position directly, and it is only necessary to separate two toolboxes connected to the toolbox. Meanwhile, the toolbox has a weight no effect on a process of taking, so that taking the toolbox is more efficient and quicker.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(10) Embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings, and the present disclosure may be implemented in a number of different ways as defined and covered by appended claims.

(11) Referring to FIG. 1 to FIG. 7, in some embodiments of the present disclosure, a toolbox group connecting structure is provided, which includes a connecting device 13 and a snap-fitting device 12. Herein the connecting device 13 and the snap-fitting device 12 are respectively installed on two adjacent toolboxes 2, and the two adjacent toolboxes 2 are inserted to mate through the connecting device 13 and the snap-fitting device 12, and a plurality of toolboxes 2 together form a trolley tool cart.

(12) Referring to FIG. 1, FIG. 2 and FIG. 3, the connecting device 13 includes a connecting plate 132, the connecting plate 132 is fixedly connected with a connecting box 131 at an upper side, the connecting box 131 is configured with an internal cavity 1314 inside, and the internal cavity 1314 is configured with a press switch 14 for sliding connection.

(13) Referring to FIG. 2, FIG. 3, FIG. 5 and FIG. 6, left and right sides of the press switch 14 each is configured with a placing slot 145, the placing slot at a lower end is configured to run through a bottom wall of the press switch 14, the placing slot 145 is closed at an upper end, and the placing slot 145 has a press spring 141 placed therein. An upper end of the press spring 141 rests against the upper end of the placing slot 145, a lower end of the press spring 141 rests against a bottom wall of the internal cavity 1314, and the internal cavity 1314 is configured with a guiding slot 1313 corresponding to a position of the press spring 141. An inner center of a side wall of the press switch 14 that away from the snap-fitting device 12 is fixedly connected to an install post 147, the install post 147 is configured to sleeve with a stop spring 143, and one end of the stop spring 147 that far away from the install post 147 is fixed connected with a stop plate 144. A side wall of the press switch 14 near the snap-fitting device 12 is configured with a penetration opening 146 corresponding to a position of the stop plate 144, and the stop plate 144 slides through the penetration opening 146. The left and right sides of the press switch 14 are further symmetrically configured with a through opening, and the through opening is fixedly connected with a bump 142 at a lower side near an end of the snap-fitting device 12. A side wall of the connecting box 131 near the snap-fitting device 12 that corresponding to the through opening at the left and right sides is configured with snap sockets 1311 for snap blocks 121 to pass through, and a position corresponding to the stop plate 144 is configured with a notch 1312 for the stop plate 144 to pass through.

(14) Referring to FIG. 5, an outside of the bump 142 facing the press switch 14 is configured with a connecting bevel.

(15) By providing the connecting bevel, it is possible to break down a horizontal squeezing force of the snap block 121 into a downward force, so that the bump 142 has a downward movement to ensure the docking of the bump 142 and the snap block 121.

(16) Referring to FIG. 6, the stop plate 144 is also fixedly connected to a limiting bump at one end near the install post 147.

(17) By providing the limiting bump, it is possible to avoid the stop plate 144 from fully popup the penetration opening 146.

(18) Referring to FIG. 1, FIG. 2, FIG. 3 and FIG. 5, the internal cavity 1314 is configured with a stepped opening at an upper end, a connecting cover 11 is movably embedded into the stepped opening, four corners of the connecting cover 11 are fixedly embedded in the connecting box 131 by means of a number of connecting bolts, an exploratory outlet is provided in a center of the connecting cover 11, and a boss is provided at the upper end of the press switch 14 and the boss extends upwardly through the exploratory outlet.

(19) Referring to FIG. 4 and FIG. 5, the snap-fitting device 12 includes a snap plate 124, the snap plate 124 is configured with a docking bayonet corresponding to a position of the connecting box 131, the docking bayonet inside corresponding to positions of two through openings of the connecting box 131 are fixedly connected to the snap blocks 121, a center of each snap block 121 is opened with a snap interface 122 for mating and snapped with the bump 142, and a backstop slot 123 is provided between two snap blocks 121 corresponding to a position of the stop plate 144 for the stop plate 144 to be pushed in.

(20) Operations of taking the toolbox are as follows. The press switch 14 is pressed to compresses the press spring 141 and at the same time drives its internal stop spring 143, the stop plate 144 and the bump 142 down. When it is moved down to a certain distance, the bump 142 is separated from the snap interface 122 (at this moment two toolboxes have been separated). When moved down to a certain distance again, the stop plate 144 is pushed into the backstop slot 123 by the action of the stop spring 143 (at this moment the stop plate 144 locks the press switch 14, so that the press switch 14 cannot be rebounded by the action of the press spring 141). At this time, the two toolboxes 2 can be separated (at this moment the switch is locked and the press switch 14 is held up by the stop plate 144, it is always open, so that a user can operate with both hands to carry out the box operation and ensure safety).

(21) Operations of stacking the toolboxes are as follows. When stacking the toolboxes, the snap block 121 is inserted through the snap socket 1311 on the connecting box 131. And when inserting, an upper surface of the snap block 121 is pressed against a lower bevel of the bump 142, so that the bump 142 is subjected to a downward decomposition force, and the bump 142 drives the press switch 14 to press down. Then a downward pressure of the press switch 14 drives the stop spring 143 to retract the stop plate 144, and after the bump 142 and the snap interface 122 of the snap block 121 are aligned, the press spring 141 jacks up the press switch 14 so that the bump 142 snaps into the snap block 121, and finally two adjacent toolboxes are tightly connected.

(22) The above are only some preferred embodiments of the present disclosure, and are not intended to limit the present invention, which may be subject to various changes and variations for an ordinary person of skill in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the scope of protection of the present invention.
