DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiment is one embodiment of the present invention, not all embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0014] This embodiment provides a foldable limiting grid frame for animal experiments.

[0015] Reference Figure 1 , Figure 2 A foldable limited grid frame for animal experiments comprises a frame 1 and a frame body 2. A pair of frames 2 are arranged side by side in the frame 1, and the sides of the pair of frames 2 close to each other are rotatably connected to the frame 1 through a rotating shaft 21, and a pair of rotating shafts 21 are provided with gears 211, and the pair of gears 211 are meshed for transmission.

[0016] In order to facilitate the control of the mutual folding angle of a pair of frames 2 , the foldable limit grid frame further includes a locking mechanism 3 , which includes a pair of locking bases 31 , a pair of locking ratchets 32 and a pair of locking spring pins 33 .

[0017] In the first embodiment, a pair of locking bases 31 are respectively sleeved on the outer sides of a pair of rotating shafts 21 and are connected to each other or fixedly connected to the frame 1, a pair of locking ratchets 32 are respectively sleeved on the pair of rotating shafts 21 and are located on the inner sides of the locking bases 31, a pair of locking spring pins 33 are respectively arranged on the pair of locking bases 31, and the ends of the locking spring pins 33 are respectively provided with locking ratchets 331 that mesh with the corresponding locking ratchets 32 for transmission, and the locking directions of the two pairs of correspondingly arranged locking ratchets 32 and locking ratchets 331 are the same.

[0018] In the above embodiment, when the pair of locking ratchets 331 are respectively engaged with the pair of locking ratchets 32, the pair of frames 2 are locked with each other, and the pair of frames 2 cannot rotate. When the locking ratchets 331 are disengaged from the corresponding locking ratchets 32 under the driving action of the locking spring pin 33, the frame 2 can be unfolded or folded.

[0019] In order to facilitate understanding of the locking situation of the locking mechanism 3, the present application is as follows: Figure 2 As a specific embodiment, the locking ratchet 32 ​​and the locking ratchet teeth 331 are meshed in a counterclockwise direction, that is, when the corresponding locking ratchet 32 ​​and the locking ratchet teeth 331 are meshed in a meshing state, the locking ratchet 32 ​​can rotate counterclockwise.

[0020] when Figure 2 When the locking ratchet teeth 331 on the left and right sides are in meshing state with the corresponding locking ratchet wheels 32, the locking ratchet wheels 32 can only rotate counterclockwise at this time, and the rotation directions of a pair of frames 2 are opposite when the frames 2 are folded or unfolded, so they are in a mutually locked state, and the frames 2 on both sides cannot move.

[0021] when Figure 2 When the locking ratchet 331 on the right is driven by the locking spring pin 33 to disengage from the corresponding locking ratchet 32, the locking ratchet 32 ​​on the left can rotate counterclockwise, and the pair of frames 2 can be driven to move away from each other, so that the frames 2 can be unfolded; when Figure 2 When the locking ratchet 331 on the left is disengaged from the corresponding locking ratchet 32 ​​under the drive of the locking spring pin 33, the locking ratchet 331 on the right can rotate counterclockwise, thereby driving a pair of frames 2 to move toward each other, thereby achieving the folding of the frames 2.

[0022] In the second embodiment, the difference from the first embodiment is that the locking base 31 is movably arranged, that is, the locking base 31 is neither connected to each other nor to the frame 1, but a retractable driving rod 11 is connected to the locking base 31, and a limiting fixture for limiting the driving rod 11 is provided on the frame 1. The limiting fixture is preferably set as a pair of baffles 12 or a pair of retaining rings 13.

[0023] When the limiting fixture is a pair of baffles 12 respectively arranged at the two sides of the frame 1. In order to facilitate the understanding of the locking situation of the above-mentioned locking mechanism 3, this application is based on Figure 3 , Figure 4 As a specific embodiment, the locking ratchet 32 ​​and the locking ratchet teeth 331 are meshed in a counterclockwise direction, that is, when the corresponding locking ratchet 32 ​​and the locking ratchet teeth 331 are meshed in a meshing state, the locking ratchet 32 ​​can rotate counterclockwise.

[0024] In the initial state, the pair of driving rods 11 respectively abut against the outer sides of the pair of baffles 12. At this time, the baffles 12 restrict the frame body 2 from folding outwards, and the driving rods 11 restrict the frame body 2 from folding inwards. At this time, the frame body 2 is in a fully unfolded state; When folding the frame 2, first retract the right driving rod 11 and drive it to rotate a certain angle in the clockwise direction, then pull out the left locking spring pin 33, and then control the right driving rod 11 to rotate counterclockwise, and then drive the right frame 2 to rotate counterclockwise through the cooperation of the locking ratchet 331 and the locking ratchet 32, and at the same time, the right frame 2 drives the left frame 2 to move clockwise through the gear 211, so that the folding of the frame 2 can be achieved; when the frame 2 is folded to a suitable angle, then the right driving rod 11 is contacted with the inner side of the baffle 12 and the left locking spring pin 33 is inserted, and finally the left driving rod 11 is contacted with the inner side of the baffle 12. At this time, the pair of frames 2 are limited to each other and the frame 2 is fixed.

[0025] When unfolding the frame 2, the left drive rod 11 is retracted and driven to rotate clockwise, and then the locking spring pin 33 on the right is pulled out, and then the left drive rod 11 is controlled to rotate counterclockwise, and then the left frame 2 is driven to rotate counterclockwise through the cooperation of the locking ratchet 331 and the locking ratchet 32, so that the frame 2 can be unfolded; when unfolded to a suitable state, the right locking spring pin 33 is then inserted and the left drive rod 11 is abutted against the inner side (or outer side) of the baffle 12, and then the right drive rod 11 is abutted against the inner side (or outer side) of the baffle 12, so that the frame 2 can be unfolded (or fully unfolded).

[0026] When the limiting fixture is a pair of clamping rings 13 respectively arranged at the two sides of the frame 1, the driving rod 11 is located at the outer side of the frame 2 and can be passed through the clamping ring 13 through telescopic control. Figure 5 , Figure 6 Taking the situation shown in as an example, when folding the frame 2, it is only necessary to pull out the locking spring pin 33 on the left side, and then drive the right frame 2 to rotate in the opposite direction through the driving rod 11 on the right side, and then drive the left frame 2 to rotate clockwise through the gear 211, so as to achieve the folding of the frame 2; when unfolding the frame 2, it is only necessary to pull out the locking spring pin 33 on the right side, and then drive the left frame 2 to rotate counterclockwise through the driving rod 11 on the left side, and then drive the right frame 2 to rotate clockwise through the gear 211, so as to achieve the unfolding of the frame 2.

[0027] In the specific implementation process, it is only necessary to replace the vertically slidable grid frame or the horizontally slidable grid frame in the prior art with the foldable grid frame of the present application, that is, to limit the three directions of the animal's movement space, thereby achieving the clamping and limiting of the animal.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
