[0015] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0016] like Figure 1-3 The diagram shows a door lock mechanism for an IVC cage according to the present invention, including a side fixing plate 1, a cage door 2, a bolt assembly and a locking assembly. The side fixing plate 1 is fixed to one side of the cage opening by screws. The cage door 2 is mounted on the other side of the cage opening by a hinge. Under the action of the hinge, the cage door 2 can be flipped to open or close the cage (the hinge is a conventional connector in the prior art).

[0017] The latch assembly is fixed to the side of the side fixing plate 1 away from the cage. The latch assembly includes a first fixing plate 3, a second fixing plate 4, a third fixing plate 5, a slot 6, and fixing holes 7. There are two first fixing plates 3, each with fixing holes 7, which are fixed to the side fixing plate 1 vertically at intervals by screws. The second fixing plate 4 is fixed to the inside of the first fixing plate 3 by welding and extends towards the side away from the side fixing plate 1. The third fixing plate 5 is fixed between the two second fixing plates 4.

[0018] like Figure 1 , 2 As shown, the first fixing plate 3, the second fixing plate 4 and the third fixing plate 5 form a slot 6. The locking component's insert plate 8 is inserted into the slot 6, thereby locking the cage door 2 (when the insert plate 8 is inserted into the slot 6, the cage door 2 is locked; when the insert plate 8 is pulled out of the slot 6, the cage door 2 is unlocked).

[0019] The locking assembly is installed on the side of the cage door 2 away from the cage box and cooperates with the latch assembly to lock the cage door 2. Figure 2 ,3 As shown, the locking assembly includes a plate 8, a rack 9, a gear 10, a rotating plate 11, a first extension plate 12, a second extension plate 13, a third extension plate 14, a fourth extension plate 15, a grip groove 16, a through groove 17, a support post 18, a support ring 19, a support plate 20, a stop plate 21, a protrusion 22, a mounting hole 23, a connecting post 24, an anti-detachment block 25, a first through hole 26, a fixing block 27, a fixing post 28, and a second through hole 29.

[0020] The cover 30 is fixed to the side of the cage door 2 away from the cage box by screws. The cover 30 is in the shape of "[", with the opening of the "[" shaped cover 30 facing the cage door 2, used to fasten the internal locking component. The gear 10 is rotatably mounted on the inside of the cover 30 (specifically, the shaft is mounted on the cover 30 by bearings, and the gear 10 is fixed to one end of the shaft by a key connection. When the breeder rotates the shaft, it drives the gear 10 to rotate).

[0021] The rotating plate 11 is fixed to the end of the rotating shaft away from the gear 10. The first extension plate 12 is fixed to the side of the rotating plate 11 away from the rotating shaft and extends away from the cage door 2. The second extension plate 13 is fixed to the side of the first extension plate 12 away from the rotating plate 11. The third extension plate 14 is fixed to the side of the second extension plate 13 away from the first extension plate 12. The fourth extension plate 15 is fixed to the side of the third extension plate 14 away from the second extension plate 13. Figure 2 As shown, the first extension plate 12, the second extension plate 13, the third extension plate 14 and the fourth extension plate 15 form a grip groove 16 inside, which makes it convenient for the breeder to hold and rotate the gear 10.

[0022] The insert plate 8 is located on the outside of the cage door 2. The rack 9 is fixed to the bottom of the insert plate 8 and meshes with the gear 10. By rotating the gear 10, the rack 9 is moved, which in turn moves the insert plate 8 to insert into the slot 6 on one side, thereby locking the cage door 2, or removing it from the slot 6 to unlock the cage door 2.

[0023] The through-slot 17 extends horizontally through the cage door 2. Two support columns 18 are fixed at intervals on the side of the cage door 2 furthest from the cage box, and both support columns 18 are located within the through-slot 17. A support ring 19 is mounted on the support column 18 via bearings, and the outer diameter of the support ring 19 is equal to the width of the through-slot 17. Therefore, when the insert plate 8 moves, the support ring 19 supports the insert plate 8, ensuring that the insert plate 8 remains horizontal and does not tilt to one side. By providing a rotating support ring 19, friction during the movement of the insert plate 8 is reduced, facilitating the opening and closing of the cage door 2.

[0024] The support plate 20 is fixed to the outside of the cage door 2 and located inside the through groove 17. The abutment plate 21 is fixed to the outside of the support plate 20 and abuts against the insert plate 8 (the abutment plate 21 and the insert plate 8 are not fixedly connected, but only abut against each other). The width of the abutment plate 21 is greater than the width of the through groove 17. When the insert plate 8 moves back and forth, the abutment plate 21 limits the insert plate 8 and prevents the insert plate 8 from falling outward.

[0025] The protrusion 22 is fixed to the top of the insert plate 8. The mounting hole 23 passes through the protrusion 22 in a horizontal direction. The connecting post 24 is inserted into the mounting hole 23 of the protrusion 22. The outer end of the connecting post 24 is fixed with an anti-detachment block 25. The diameter of the anti-detachment block 25 is larger than the diameter of the mounting hole 23, so as to prevent the connecting post 24 from coming out of the mounting hole 23 when stretched.

[0026] The first through hole 26 is located at the end of the connecting post 24 away from the anti-detachment block 25. The fixing block 27 is fixed to the outside of the cage door 2. The fixing post 28 is fixed to the side of the fixing block 27 near the protrusion 22. The second through hole 29 is located at the end of the fixing post 28 near the connecting post 24. A tension spring is installed between the connecting post 24 and the fixing post 28 (specifically, the hooks at both ends of the tension spring are hooked into the first through hole 26 and the second through hole 29, respectively, as shown). Figure 3 As shown, the tension spring is not shown in the figure; the tension spring is a conventional elastic element.

[0027] By setting a tension spring, when the insert plate 8 is moved out of the slot 6, the tension spring is stretched. When the cage door 2 is closed, the tension spring's reset action helps the insert plate 8 move and insert into the slot 6 to lock the cage door 2.

[0028] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
