DETAILED DESCRIPTION

[0022] The technical features of the present invention are further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] The present invention provides a door lock structure for a pet cage as shown in FIG. 1 and FIG. 2, and a use method thereof. The pet cage comprises a cage body 1, wherein at least one entrance is arranged on the side of the cage body 1, and a cage door 2 is arranged at the entrance; a plurality of pivot rings 3 is arranged on one side of the cage door 2, sleeves a door frame on the edge of the entrance and is rotatable about the door frame; at least two limit sliding rods 7 which are parallel to each other are arranged on the cage door 2, and a lock that is slidable on the limit sliding rods 7 is installed on the limit sliding rods 7; the lock comprises a traveling mechanism 4 that clamps the limit sliding rods 7, and a plurality of tension springs 6 is installed on one side of the traveling mechanism 4 close to the door frame, wherein the other end of each tension spring 6 is fixed to the edge of the cage door 2; a plurality of lock bolt assemblies 5 that moves synchronously with the traveling mechanism 4 is also arranged on the traveling mechanism 4, and the lock bolt assemblies 5 are matched with and locked with lock hole mechanisms provided on the corresponding door frame.

[0024] Each of the cage body 1 and the cage door 2 is of a grid mesh structure.

[0025] Each lock bolt assembly 5 comprises at least two lock bolts, which are located in the middle and on the upper and lower ends of the cage door 2, respectively. In this way, the cage door 2 and the door frame can be fixed more firmly, thereby avoiding the problem of gaps formed by the deformation of upper and lower ends. Each lock bolt assembly 5 are connected to the traveling mechanism 4 through a vertical arm perpendicular to the corresponding limit sliding rod 7. Preferably, each lock bolt assembly 5 is a closed area wound by an iron wire, the area being of a “C” or “E” structure. When the area is of the “C” structure, the middle lock bolt is arranged on the traveling mechanism.

[0026] In consideration of relatively large spans of the lock bolt assemblies 5, a plurality of locking bolt limiting slideways 9 is arranged on the outer side of the vertical arm between the traveling mechanism 4 and each locking bolt, and the vertical arm slides in the locking bolt limiting slideways 9. By means of such arrangement, the lock bolt assemblies 5 can be kept from deforming even under the action of an external force, so that the lock bolt assemblies always move along a virtual plane where the cage door 2 is located.

[0027] As shown in FIG. 3, each lock hole mechanism is fixed to a lock ring on the door frame or the door frame itself; and the uppermost and lowermost sides of the cage door 2 are arranged on the outside of the door frame, such that the cage door 2 will be restricted by the door frame and cannot rotate into the cage.

[0028] When each lock hole mechanism is a lock ring, the lock ring is welded to a vertical fence of the cage body.

[0029] The traveling mechanism 4 comprises two traveling units, which are combined together by screws and sleeved with the limit sliding rods 7 through limiting holes reserved on the inner sides of the two traveling units. In order for easy installation, a virtual cylinder of each limiting hole 7 is divided into two equal limiting hole units by a symmetry plane passing through its center axis, and the two limiting hole units are respectively formed on the sides, which are close to each other, of the two traveling units.

[0030] The cage body 1 is composed of six surfaces, and every two adjacent surfaces are fixed by fixing hooks.

[0031] A handle 8 is arranged on the top of the cage body 1, for being convenient to carry and move.

[0032] The use method of the cage door for the pet cage comprises the following steps:

[0033] (1) when the cage door needs to be closed, the traveling mechanism is pulled with a hand to move toward one side of the pivot ring to drive the lock bolt to move until the end of the lock bolt do not exceed the corresponding lock hole mechanism; the hand is loosened after the cage door is closed; the tension springs drive the traveling mechanism to reset; the traveling mechanism drives the lock bolt to move toward one side of the corresponding lock hole mechanism, and to lock the cage door together with the lock hole mechanism, and

[0034] (2) when the cage door needs to be opened, the traveling mechanism is pulled with a hand to move toward one side of the pivot ring to drive the lock bolt to move until the end of the lock bolt do not exceed the corresponding lock hole mechanism; and the hand is loosened after the cage door is opened.

[0035] The above embodiments are merely preferred embodiments of the present invention but are not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, a person skilled in the art should understand: the technical solutions described in the foregoing embodiments may also be modified, or some of the technical features may be equivalently replaced. Thus, any modification, equivalent replacement, improvement and so on made within the spirit and principle of the present invention shall be encompassed by the protection scope of the present invention.
