Although the cage in the aforementioned patent improves the folding effect of the cage door, if only one animal needs to be caught inside the cage, the cage door opening is too large, and the animal can easily escape from the extra space. Therefore, it is necessary to cover the extra space of the cage door, which increases the difficulty of catching the animal. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide a cage grille door to solve the above-mentioned problems, thereby addressing the issue that the opening of the cage door in the prior art is easily too large when fully opened.

[0007] (II) Technical Solution

[0008] This utility model is achieved through the following technical solution: a cage grille door.

[0009] The device includes a door frame, a grille mechanism and a positioning mechanism in the middle of the door frame. The grille mechanism includes a sliding groove and equidistant grille bars. The sliding groove is located in the middle of the door frame. Each grille bar has a sliding block fixedly connected to both ends. Each sliding block is slidably connected to the sliding groove. The positioning mechanism includes a positioning rod, a positioning ring, a locking block and a positioning tube. The positioning ring is fixedly connected to the door frame.

[0010] Preferably, a connecting rope is fixedly connected to the top of the door frame, and several sliding blocks pass through the bottom of the connecting rope in sequence. Each sliding block is fixedly connected to the connecting rope. The connecting rope connects the several sliding blocks together and arranges the several sliding blocks at equal intervals inside the sliding groove.

[0011] Preferably, a first telescopic spring is fixedly connected inside the door frame, and a buffer pad is fixedly connected to the top of the first telescopic spring. The buffer pad is fixedly connected to the bottommost sliding block. The sliding block is pulled by the first telescopic spring, so that several grid bars are arranged at equal intervals inside the door frame.

[0012] Preferably, the surface of the positioning rod is fixedly connected with equidistantly arranged positioning blocks, and each positioning block abuts against the adjacent grid rod. The positioning tube is fixedly connected to one of the middle grid rods. The positioning blocks are used to position and fix the position between the positioning rod and the grid rod, thereby improving the impact resistance of the grid rod during use.

[0013] Preferably, the locking block is slidably connected to the positioning rod and to the positioning ring. A second telescopic spring is fixedly connected to the surface of the locking block and to the positioning rod. The second telescopic spring provides a thrust to the locking block, so that the locking block and the positioning ring are tightly locked together.

[0014] Preferably, a fixing sleeve is fixedly connected to the middle of the positioning rod, and a pull rod is slidably connected inside the fixing sleeve. A pull rope is fixedly connected to the middle of the locking block, and the pull rope passes through the positioning rod and is fixedly connected to the pull rod. The pull rod drives one end of the pull rope to move, so that the other end of the pull rope drives the locking block away from the positioning ring, thereby disengaging the positioning rod from the connection state with the door frame.

[0015] Preferably, a sliding tube is slidably connected inside the positioning tube, and the top end of the sliding tube is fixedly connected to the positioning rod. A third telescopic spring is fixedly connected inside the positioning tube, and the top end of the third telescopic spring is rotatably connected to the positioning rod.

[0016] Preferably, a connecting block is fixedly connected to the surface of the sliding tube, and a first sliding groove and a second sliding groove adapted to the connecting block are opened inside the positioning tube. The positioning rod is fixed horizontally by the connecting block sliding inside the second sliding groove, thereby improving the stability of the positioning rod operation.

[0017] This utility model provides a cage grille door, which has the following beneficial effects:

[0018] 1. This cage grille door uses a sliding groove to position the sliding block, which then fixes the grille rods. The grille rods are evenly spaced inside the door frame, improving the grille door's isolation performance for animals inside the cage. The positioning tube fixes the positioning rod, and the locking block engages with the positioning ring to fix the positioning rod to the door frame surface, thereby fixing several grille rods and improving the stability of the grille door. When it is necessary to remove the animal, only the space required for use is opened, preventing the cage opening from being too large and the animal from escaping, thus improving the convenience of animal removal.

[0019] 2. The cage's grille door connects several sliding blocks together via connecting ropes, and these blocks are equidistantly arranged inside the sliding groove. A first telescopic spring pulls the sliding blocks, causing the grille bars to be equidistantly arranged inside the door frame. A buffer pad cushions the sliding blocks, preventing them from being pulled by the first telescopic spring and causing rapid impact to the sliding groove, thus improving the stability of the device's reset. A positioning block positions and fixes the positioning rod and grille bar, preventing the grille bar from easily deforming when an animal collides with it, thus improving the grille bar's impact resistance during use. A second telescopic spring provides thrust to the locking block, causing the locking block to be tightly engaged with the positioning ring, thereby fixing the positioning rod to the surface of the door frame.

[0020] 3. The cage grille door uses a fixed sleeve to position the pull rod. The pull rod moves one end of the pull rope, causing the other end of the rope to move the locking block away from the positioning ring, thus disengaging the positioning rod from the door frame. This allows personnel to move the grille up and down to remove the animal from the cage. The positioning rod is fixed to one of the middle grille bars by sliding through the sliding tube inside the positioning tube. A third telescopic spring provides tension to the positioning rod, ensuring a tight fit between the positioning rod and the grille bar. The connecting block slides in the first sliding groove to fix the positioning rod vertically, and slides in the second sliding groove to fix the positioning rod horizontally, improving the stability of the positioning rod's operation.

[0030] This utility model embodiment provides a cage grille door.

[0031] Example 1:

[0032] Please see Figure 1 and Figure 2 The cage includes a door frame 1, with a grid mechanism 2 and a positioning mechanism 3 in the middle of the door frame 1. The grid mechanism 2 includes a sliding groove 201 and grid rods 202 arranged at equal intervals. The sliding groove 201 is located in the middle of the door frame 1. Each grid rod 202 has a sliding block 203 fixedly connected to both ends, and each sliding block 203 is slidably connected to the sliding groove 201. The sliding block 203 is positioned by the sliding groove 201, and the grid rod 202 is fixed by the sliding block 203. The grid rods 202 are arranged at equal intervals inside the door frame 1, which improves the isolation performance of the grid door for animals inside the cage.

[0033] A connecting rope 204 is fixedly connected to the top of each door frame 1. Several sliding blocks 203 pass through the bottom of the connecting rope 204 in sequence, and each sliding block 203 is fixedly connected to the connecting rope 204. The connecting rope 204 connects the several sliding blocks 203 together and arranges the several sliding blocks 203 at equal intervals inside the sliding groove 201.

[0034] A first telescopic spring 206 is fixedly connected inside the door frame 1. A buffer pad 205 is fixedly connected to the top of the first telescopic spring 206, and the buffer pad 205 is fixedly connected to the bottom sliding block 203. The first telescopic spring 206 pulls the sliding block 203, so that several grid bars 202 are arranged equidistantly inside the door frame 1. The buffer pad 205 provides cushioning for the sliding block 203, preventing the first telescopic spring 206 from pulling the sliding block 203 to quickly impact the sliding groove 201 and causing damage to the sliding groove 201, thereby improving the stability of the device's reset.

[0035] Example 2;

[0036] Please refer to it again. Figure 1 , Figure 3 and Figure 5 The positioning mechanism 3 includes a positioning rod 301, a positioning ring 303, a locking block 304, and a positioning tube 309. The positioning ring 303 is fixedly connected to the door frame 1. The positioning rod 301 is fixed through the positioning tube 309. The positioning rod 301 is fixed to the surface of the door frame 1 by locking the locking block 304 with the positioning ring 303, thereby fixing several grille rods 202 and improving the stability of the grille door.

[0037] The surface of the positioning rod 301 is fixedly connected with equidistantly arranged positioning blocks 302, and each positioning block 302 abuts against the adjacent grid rod 202. The positioning tube 309 is fixedly connected to one of the grid rods 202 in the middle. The positioning blocks 302 are used to position and fix the position between the positioning rod 301 and the grid rod 202, so as to prevent the grid rod 202 from easily deforming when the animal collides with it, and improve the impact resistance of the grid rod 202 during use.

[0038] The locking block 304 is slidably connected to the positioning rod 301, and the locking block 304 is slidably connected to the positioning ring 303. A second telescopic spring 305 is fixedly connected to the surface of the locking block 304, and the second telescopic spring 305 is fixedly connected to the positioning rod 301. The second telescopic spring 305 provides a pushing force to the locking block 304, so that the locking block 304 and the positioning ring 303 are tightly locked together, thereby fixing the positioning rod 301 to the surface of the door frame 1.

[0039] A fixed sleeve 307 is fixedly connected to the middle of the positioning rod 301. A pull rod 308 is slidably connected inside the fixed sleeve 307. A pull rope 306 is fixedly connected to the middle of the locking block 304. The pull rope 306 passes through the positioning rod 301 and is fixedly connected to the pull rod 308. The fixed sleeve 307 positions the pull rod 308. The pull rod 308 drives one end of the pull rope 306 to move, causing the other end of the pull rope 306 to move the locking block 304 away from the positioning ring 303. This allows the positioning rod 301 to disengage from the door frame 1, making it easier for personnel to move the grid bar 202 up and down and remove the animal from inside the cage.

[0040] Example 3;

[0041] Please refer to it again. Figure 4 and Figure 5 The positioning tube 309 is slidably connected to a sliding tube 310, and the top end of the sliding tube 310 is fixedly connected to the positioning rod 301. The positioning tube 309 is fixedly connected to a third telescopic spring 311, and the top end of the third telescopic spring 311 is rotatably connected to the positioning rod 301. By sliding the sliding tube 310 inside the positioning tube 309, the positioning rod 301 is fixed together with a middle grid rod 202. The third telescopic spring 311 provides tension to the positioning rod 301, so that the positioning rod 301 and the grid rod 202 fit tightly together.

[0042] A connecting block 314 is fixedly connected to the surface of the sliding tube 310. The positioning tube 309 has a first sliding groove 312 and a second sliding groove 313 that are adapted to the connecting block 314. The positioning rod 301 is fixed vertically by the connecting block 314 sliding inside the first sliding groove 312, and the positioning rod 301 is fixed horizontally by the connecting block 314 sliding inside the second sliding groove 313, thereby improving the stability of the positioning rod 301 during operation.

[0043] In use, when it is necessary to simply grasp one animal inside the cage, first pull the pull rod 308 outward, causing the other end of the pull rope 306 to move the locking block 304 away from the positioning ring 303. Then, pull the positioning rod 301 outward by the handle, causing the connecting block 314 to move away from the first slide groove 312. Then, rotate the positioning rod 301 so that the connecting block 314 is located inside the second slide groove 313. Release the handle of the positioning rod 301, and the third telescopic spring 311 provides tension to the positioning rod 301, causing the connecting block 314 to slide inside the second slide groove 313, thus horizontally positioning the positioning rod 301. The positioning rod 301 is fixed in place to prevent it from rotating arbitrarily when the animal is removed. By moving the bottom grid rod 202 upward, a hole is opened at the bottom of the door frame 1 to allow the animal to be removed, while the remaining grid rods 202 still block any excess space in the door frame 1. After an animal is removed, the first telescopic spring 206 pulls the sliding block 203 to reset several grid rods 202, preventing the animal from escaping from the cage. Through the above device, only a space sufficient for use is opened when the animal needs to be removed, preventing the cage opening from being too large and the animal from escaping from the cage, thus improving the convenience of animal removal.
