[0027] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0028] like Figure 1 , 2 The diagram shows a schematic of the cage door lock for IVC cages according to this utility model. The cage door lock is installed on one side of the animal cage and is used to open and close the cage. The first cage side panel 2 and the second cage side panel 3 are both perpendicular to the cage bottom plate 1 and are fixed to the top edge of the cage bottom plate 1 respectively. The two first cage side panels 2 are arranged opposite each other, and the second cage side panel 3 is located on the same side of the two first cage side panels 2 and is perpendicularly connected to the first cage side panels 2, together forming a rectangular frame. The cage top plate 4 is fixed to the top edges of the first cage side panels 2 and the second cage side panels 3, forming a closed top surface.

[0029] The cage bottom plate 1, the first cage side plate 2, the second cage side plate 3, and the cage top plate 4 form a hollow feeding cavity for raising laboratory animals (such as white mice). The side of the first cage side plate 2 away from the second cage side plate 3 forms an opening for installing the cage door 15.

[0030] There are two first slide rails 5, which are vertically fixed to the opening side of the cage box by screws (that is, fixed to the side of the first cage box side plate 2 away from the second cage box side plate 3). The inner side of the cage door 15 is fixed with a first slider 6 that cooperates with the first slide rail 5 by screws. The first slider 6 is installed on the first slide rail 5, so the cage door 15 can slide in the vertical direction to open or close the cage box (by setting the mutually cooperating slide rail 5 and slider 6, the stability of the opening or closing of the cage door 15 is improved).

[0031] The abutment 19 is integrally formed on the inner side of the top of the cage door 15 and extends toward the side closer to the cage box. When the cage door 15 is closed, the cage door 15 is locked by the locking assembly. At this time, the abutment 19 abuts against the upper surface of the slide rail 5 to seal the gap between the cage door 15 and the top of the cage box.

[0032] A handle 22 is installed on the outside of the cage door 15 (i.e., the side of the cage door 15 away from the cage box). The handle 22 allows the zookeeper to easily grasp and open or close the cage door 15. Figure 1 As shown, handle 22 is installed horizontally for easy gripping by the feeder.

[0033] There are at least two sets of locking components, installed at intervals between the cage box and the cage door 15, such as... Figure 3 , 4 As shown, each locking assembly includes a mounting block 7, a slot 8, a locking groove 9, a through groove 10, a limiting part 11, a locking block 12, a spring 13, a stop ball 14, a cage door 15, a plug block 16, a first arc-shaped part 17, a second arc-shaped part 18, a stop plate 19, a partition plate 20, and a fixing plate 21. The fixing plate 21 is fixed to one side of the cage box (specifically, the fixing plate 21 is fixed to the side of the cage box bottom plate 1 away from the second cage box side plate 3), and the fixing plate 21 is used to support the various structures above.

[0034] There are two mounting blocks 7, which are installed at intervals on the top of the fixing plate 21 by screws, and a slot 8 is formed between the two mounting blocks 7 for the insertion block 16 to be inserted. The locking groove 9 is opened on the outside of the two mounting blocks 7, and the through groove 10 horizontally penetrates the mounting block 7 and connects the locking groove 9 and the slot 8, and the through groove 10 is coaxial with the locking groove 9.

[0035] The inner wall of the locking groove 9 is provided with an internal thread, and the outer wall of the locking block 12 is provided with an external thread that mates with it. Therefore, the locking block 12 is screwed into the locking groove 9 to abut against one side of the spring 13 (the side of the locking block 12 away from the spring 13 has a hexagonal groove for easy installation with a wrench).

[0036] The limiting part 11 is inclinedly disposed on the side of the through groove 10 away from the locking groove 9, such as Figure 4 As shown, the diameter of the limiting part 11 near the slot 8 is smaller than the diameter of the limiting part 11 away from the slot 8, thus limiting the ball 14 in the through groove 10. When the cage door 15 is opened, this prevents the spring 13 from pushing the ball 14 out of the through groove 10. The spring 13 is installed in the through groove 10, with one side of the spring 13 abutting against the side wall of the ball 14 and the other side of the spring 13 abutting against the locking block 12. The spring 13 drives the ball 14 to move, thereby completing the self-locking of the cage door 15.

[0037] During installation, first insert the ball 14 into the through groove 10 from one side of the lock groove 9, then insert the spring 13 into the through groove 10 from one side of the lock groove 9, and finally screw the lock block 12 into the lock groove 9.

[0038] The insert 16 is fixed to the bottom of the cage door 15 and cooperates with the slot 8. The first arc-shaped part 17 is disposed on both sides of the insert 16 and cooperates with the ball stop 14. The second arc-shaped part 18 is disposed on both sides of the bottom of the insert 16 and cooperates with the ball stop 14.

[0039] The partition 20 is fixed to the top of the fixing plate 21, and the partition 20 is higher than the mounting block 7. By setting the partition 20, the mounting block 7 is separated to seal the gap between the cage door 15 and the bottom of the cage box.

[0040] When the cage door 15 descends to close the cage box, the insert 16 at the bottom of the cage door 15 descends and inserts into the slot 8 between the two mounting blocks 7. At this time, the second arc-shaped part 18 first contacts the inner side wall of the two abutment balls 14. When the insert 16 descends, it pushes against the abutment balls 14 on both sides and moves inward (the spring 13 is compressed, and the arc-shaped contact surface facilitates pushing the abutment balls 14 inward by setting the arc-shaped second arc-shaped part 18). When the insert 16 descends past the abutment balls 14, under the reset action of the spring 13, it pushes the abutment balls 14 outward until the abutment balls 14 abut against the first arc-shaped parts 17 on both sides of the insert 16 to lock the insert 16 and the cage door 15. When the cage door 15 is raised to open the cage box, the keeper holds the handle and lifts the cage door 15 upward. At this time, the cage door 15 drives the insert block 16 to rise. When the insert block 16 rises, it pushes the abutment balls 14 on both sides inward (the spring 13 is compressed again, and the arc-shaped first arc part 17 is provided, and the arc-shaped contact surface facilitates pushing the abutment balls 14 inward). After the insert block 16 is pulled out of the slot 8, under the reset action of the spring 13, it pushes the abutment balls 14 outward. The abutment balls 14 reset, and under the blocking action of the limiting part 11, the abutment balls 14 are prevented from falling out of the through groove 10.

[0041] The cage door lock of this utility model for IVC cages has a simple structure. By installing a mechanical locking component between the cage door 15 and the cage box, the cage door is locked by the mechanical structure when the cage box is closed. There is no leakage, which is safer. Moreover, the mechanical locking structure does not waste power resources and saves costs. At the same time, the structure is simple and easy to install.
