DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a technical solution: a veterinary anti-escape device, comprising a base 1 and a box body 2 fixed on the top of the base 1, two scissor-shaped expansion components 3 are symmetrically arranged on the inner sides of both ends of the box body 2, four rectangularly arranged fixing components 4 are arranged on the two expansion components 3, a driving component 6 is arranged in the box body 2, and guide wheel components 5 are arranged at both ends of the box body 2 to synchronously open the two expansion components 3 under the drive of the driving component 6, and elastic components 7 are arranged on the two expansion components 3 to assist the expansion components 3 to be tightened when they are retracted, such as Figure 1 As shown, the device is in a retracted state, which makes it easy to pull the animal above the device. Figure 2 As shown, the device is in the unfolded state, which is convenient for fixing the legs of the animal to prevent the animal from breaking free.

[0024] See also Figure 3 and Figure 4 The expansion component 3 includes a slide 31 and two movable rods 32 hinged on the slide 31. Slide blocks 311 are provided on both sides of the slide 31. A slide groove 22 that slidably cooperates with the slide block 311 is provided in the box body 2. The slide groove 22 is arranged along the length direction of the box body 2.

[0025] See also Figure 2 and Figure 5The fixing assembly 4 includes a strap 42 , one end of which is fixed with a female buckle 41 , the female buckle 41 is fixed to the outer side of the end of the movable rod 32 , and the other end of the strap 42 is fixed with a sub-buckle 43 that can be snap-connected with the female buckle 41 .

[0026] See also Figure 3 The driving assembly 6 includes a dual-axis motor 61, which is fixed to the inner side of the middle part of the box body 2. The two output ends of the dual-axis motor 61 are fixed with threaded rods 62 horizontally arranged along the length direction of the box body 2. The threaded rods 62 penetrate the slide 31 and are threadedly connected with the slide 31. It should be noted that the threads on the threaded rods 62 at both ends of the dual-axis motor 61 are in opposite directions. The dual-axis motor 61 drives the threaded rods 62 to rotate. Through the threaded cooperation between the threaded rods 62 and the slide 31, and at the same time, under the sliding limit of the slider 311 and the slide groove 22, the two slides 31 can move horizontally synchronously, and the movement directions of the two slides 31 are opposite.

[0027] See also Figure 3 and Figure 5 The guide wheel assembly 5 includes a fixing frame 51. Openings 21 are provided on both sides of the end of the box body 2. The fixing frame 51 is fixed between the openings 21 on both sides. The threaded rod 62 is rotatably connected to the fixing frame 51. Both ends of the fixing frame 51 are rotatably connected with rollers 52 that are axially perpendicular to the threaded rod 62. The two movable rods 32 are provided with bayonet holes 321 on the opposite side away from one end of the slide 31. The bayonet holes 321 are adapted in shape to the rollers 52. When the slide 31 moves from the middle of the box body 2 to the end, the rollers 52 on both sides are squeezed out of the bayonet holes 321 and squeeze the movable rods 32 on both sides to unfold from the openings 21 at both ends of the box body 2.

[0028] See also Figure 3 and Figure 4 The elastic component 7 includes a tension spring 72, and spring rods 71 ​​are fixed at both ends of the tension spring 72. The two spring rods 71 ​​are fixed on the two movable rods 32 respectively. When the slide 31 moves from the middle to the end of the box body 2, the opening of the movable rods 32 on both sides can stretch the tension spring 72. When the two slides 31 approach from the end to the middle of the box body 2, under the tension of the tension spring 72, the two movable rods 32 can fit against the roller 52 and gradually shrink into the box body 2 until the roller 52 is stuck in the bayonet 321.

[0029] The working principle and use process of the utility model: In the initial state, the device is as follows Figure 1 and Figure 3As shown, the animal can be pulled above the device, the dual-axis motor 61 is turned on, and the dual-axis motor 61 drives the threaded rod 62 to rotate. The threaded rod 62 cooperates with the thread of the slide seat 31, and the slide seat 31 is limited by the sliding of the slider 311 and the slide groove 22, so that the slide seat 31 can move from the middle of the box body 2 to the end. In this process, the rollers 52 on both sides are squeezed out of the bayonet 321, and the movable rods 32 on both sides are squeezed to unfold from the openings 21 at both ends of the box body 2, and then the four straps 42 are passed around the legs of the animal and fixed by inserting the sub-buckle 43 into the female buckle 41 to prevent the animal from breaking free;

[0030] During the above process, the opening of the movable rods 32 on both sides can stretch the tension spring 72. Therefore, after use, when the two slide seats 31 are driven from the ends of the box body 2 to the middle by the reverse rotation of the dual-axis motor 61, the two movable rods 32 can fit against the roller 52 and gradually shrink into the box body 2 under the tension of the tension spring 72 until the roller 52 is stuck in the bayonet 321. At this time, the movable rods 32 on both sides can be completely retracted into the box body 2 through the openings 21 at both ends to save space and facilitate the next use.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
