DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] See also Figures 1 to 11 A restraining frame for veterinary treatment, comprising a main frame body 100, a passage 101 for livestock to pass through is arranged in the main frame body 100, doors 102 are rotatably installed on the main frame body 100 and at both ends of the passage 101, and also comprising a flap 200, a positioning frame 300, a limiting member 400 and two driving mechanisms 500;

[0038] The flap 200 is disposed on the side of the main frame 100;

[0039] A positioning frame 300 is used to cooperate with the flap 200 to limit and fix the livestock. A rotating shaft 301 is connected to one side of the positioning frame 300, and both ends of the rotating shaft 301 are rotatably connected to the top of the flap 200;

[0040] A limiting member 400, one side of which is connected to the A rotating shaft 301, and the limiting member 400 is used to prevent the A rotating shaft 301 from rotating around the axis of the A rotating shaft 301;

[0041] Two driving mechanisms 500 are installed on the main frame 100 and are symmetrically arranged at both ends of the flap 200. The driving mechanism 500 includes a B shaft 501, an A support frame 502, a B support frame 503, a C shaft 504, an A driving component and a B driving component. The B shaft 501 is installed at the bottom end of the A support frame 502, and the top end of the B support frame 503 is connected to the flap 200 through the C shaft 504. The A driving component is used to drive the A support frame 502 to rotate around the axis of the B shaft 501, and the A driving component can synchronously drive the flap 200 to rotate around the axis of the C shaft 504. One side of the B support frame 503 is connected to the B driving component for driving the B support frame 503 to move along the height direction of the A support frame 502.

[0042] When veterinarians treat livestock, they need to use restraints to limit and fix the livestock to prevent the livestock from moving during the treatment process. When the livestock's abdomen, legs and other areas need to be treated, such as sheep, the livestock needs to be turned over. Most existing restraints with turning over function use an integral rotating frame to fix the livestock on the frame to achieve the turning over of the livestock. Before turning over, the livestock needs to be fixed by straps and other restraining parts. The process is relatively cumbersome, which reduces the veterinarian's treatment efficiency.

[0043] To this end, the present application provides a passage 101 for livestock to pass through in the main frame 100. When in use, one door 102 at both ends of the passage 101 is opened, and the other door 102 is closed. The livestock is driven into the passage 101, and the opened door 102 is closed. At this time, the rotation restriction of the limiting member 400 on the A rotating shaft 301 is released, and the positioning frame 300 is close to the livestock. The limiting member 400 is used to prevent the A rotating shaft 301 from rotating around its own axis. The positioning frame 300 cooperates with the flap 20 0 limits and fixes the livestock, and then drives the A support frame 502 to rotate around the B rotation axis 501 through the A driving component in the driving mechanism 500, and the A support frame 502 drives the B driving component and the flap 200 to rotate and tilt around the B rotation axis 501, and the positioning frame 300 tilts synchronously with the flap 200, and the flap 200 cooperates with the positioning frame 300 to lift the livestock. At the same time, the A driving component synchronously drives the flap 200 to rotate around the axis of the C rotation axis 504, and the flap 200 cooperates with the positioning frame 300 to turn the livestock over;

[0044] In order to facilitate the limiting and fixing of livestock and improve the efficiency of livestock restraint, the width of the channel 101 will not be set too wide. However, some livestock have long legs, such as the small-tailed Han sheep, commonly known as "high-legged sheep". As a result, when the livestock turn over, the feet of the livestock are easily in contact with the side walls of the channel 101, resulting in the livestock being unable to turn over or being injured. For this reason, the present application drives the B support frame 503 to move along the height direction of the A support frame 502 while the flap 200 tilts and rotates with the A support frame 502. Therefore, when the livestock turns over, the legs of the livestock can be further away from the side walls of the channel 101, which can effectively prevent the livestock with long legs from being unable to turn over or the livestock from being easily injured during the turning process.

[0045] In one embodiment of the present invention, the limiting member 400 includes a limiting ring 401, a latch 402, a fixing seat 403, an elastic member 404, and a plurality of plug holes 405 provided on the limiting ring 401. The limiting ring 401 is fixedly sleeved on one end of the A rotating shaft 301. The plurality of plug holes 405 are arranged in a circular array with the axis of the limiting ring 401 as the center. The latch 402 can be partially inserted into one of the plug holes 405. The outer wall of the latch 402 is slidably connected to the fixing seat 403. The bottom end of the fixing seat 403 is fixedly connected to the flap 200. One end of the elastic member 404 is fixedly connected to the fixing seat 403. The elastic member 404 is a spring.

[0046] When the limiting member 400 is required to prevent the rotation of the A rotating shaft 301, the end of the latch 402 is inserted into a plug hole 405 on the limiting ring 401, and the latch 402 cooperates with the fixing seat 403 to prevent the limiting ring 401 from rotating, that is, the A rotating shaft 301 can be prevented from rotating;

[0047] When the limiting member 400 is required not to hinder the rotation of the A rotating shaft 301 , the latch 402 is pulled, the elastic member 404 is stretched, the latch 402 is disengaged from the insertion hole 405 , and the limiting ring 401 is not restricted, so that the A rotating shaft 301 can rotate.

[0048] In one embodiment of the present invention, the A driving component includes a base 505, an A telescopic driving member 506 and a rotation driving assembly, the A telescopic driving member 506 adopts a telescopic cylinder or a hydraulic cylinder, the B rotating shaft 501 is externally connected to the A support frame 502 for rotation, one end of the B rotating shaft 501 is fixedly connected to the base 505, the bottom of the base 505 is fixedly installed on the main frame body 100, the moving end of the A telescopic driving member 506 is hinged to the A support frame 502, the fixed end of the A telescopic driving member 506 is hinged to the main frame body 100, one end of the C rotating shaft 504 is fixedly connected to the flap 200, one side of the B support frame 503 is slidably connected to the A support frame 502, the C rotating shaft 504 is externally connected to the B support frame 503 for rotation, and one side of the C rotating shaft 504 is connected to a rotation driving assembly for driving the C rotating shaft 504 to rotate around its own axis;

[0049] When the moving end of the A telescopic driving member 506 is extended and retracted, the moving end of the A telescopic driving member 506 pushes the A support frame 502. Under the support of the B rotating shaft 501, the A support frame 502 rotates and tilts around the axis of the B rotating shaft 501. The A support frame 502 drives the B support frame 503 to tilt synchronously. The B support frame 503 drives the flap 200 to tilt through the C rotating shaft 504. The flap 200 cooperates with the positioning frame 300 to lift the livestock. At the same time, the rotating drive assembly drives the C rotating shaft 504 to rotate. The C rotating shaft 504 drives the flap 200 to rotate. The flap 200 cooperates with the positioning frame 300 to turn over the livestock.

[0050] In one embodiment of the present invention, the rotary drive assembly includes an A gear 507, a B gear 508, an outer rod 509, an inner rod 510, a C gear 511 and a D gear 512, wherein the A gear 507 is fixedly sleeved at the end of the B rotating shaft 501, one side of the A gear 507 is meshed with the B gear 508, the B gear 508 is fixedly sleeved at the bottom end of the outer rod 509, a sliding cavity is provided inside the outer rod 509, the inner side wall of the sliding cavity of the outer rod 509 is slidably connected to the outer side wall of the inner rod 510, the outer side wall of the bottom end of the outer rod 509 is rotatably connected to the A support frame 502, the outer side wall of the upper end of the inner rod 510 is rotatably connected to the B support frame 503, the C gear 511 is fixedly sleeved at the top end of the outer rod 509, one side of the C gear 511 is meshed with the D gear 512, and the D gear 512 is fixedly sleeved on the outside of the C rotating shaft 504;

[0051] When the A support frame 502 rotates and tilts around the axis of the B rotating shaft 501, the A support frame 502 drives the outer rod 509 to rotate and tilt. Since the A gear 507 is fixed on the B rotating shaft 501, and the B rotating shaft 501 is fixed on the base 505, the A gear 507 is fixed, and the B gear 508 rotates when the outer rod 509 rotates around the axis of the B rotating shaft 501. The B gear 508 drives the outer rod 509 to rotate. Since the inner rod 510 is slidably connected to the outer rod 509, the outer rod 509 drives the inner rod 510 to rotate when it rotates. The rod 510 drives the C gear 511 to rotate, the C gear 511 drives the D gear 512 to rotate, and the D gear 512 drives the flap 200 to rotate through the C shaft 504, so that the flap 200 rotates and tilts with the A support frame 502 and rotates around the C shaft 504 at the same time, and the flap 200 cooperates with the positioning frame 300 to lift and turn over the livestock, and during the turning over process, the flap 200 gradually moves away from the side wall of the channel 101, which can effectively complete the turning over of livestock with longer legs.

[0052] In one embodiment of the present invention, the outer rod 509 is a threaded sleeve, the outer side wall of the threaded sleeve is threadedly connected to the B support frame 503, and the outer rod 509 is a B driving component;

[0053] When the outer rod 509 rotates, since one side of the B support frame 503 is slidingly connected to the A support frame 502, the outer rod 509 drives the B support frame 503 to move along the height direction of the A support frame 502, and the A support frame 502 drives the flap 200 to move through the C shaft 504, so that when the flap 200 cooperates with the positioning frame 300 to turn over the livestock, the flap 200 can be further away from the side wall of the channel 101, and when the flap 200 cooperates with the positioning frame 300 to turn over the livestock, the height of the flap 200 can be increased, that is, the height of the livestock is increased, so as to facilitate the veterinarian to treat the livestock.

[0054] Since the number of rotations of the outer rod 509 is limited, the movement range of the B support frame 503 along the height direction of the A support frame 502 is limited. Therefore, in one embodiment of the present invention, the outer wall of the outer rod 509 is movably connected to the B support frame 503, and the B driving component is a B telescopic driving member 513. The fixed end of the B telescopic driving member 513 is fixedly connected to the A support frame 502, and the movable end of the B telescopic driving member 513 is fixedly connected to the B support frame 503. The B telescopic driving member 513 is a telescopic cylinder or a hydraulic cylinder.

[0055] When the moving end of the B telescopic driving member 513 moves, it drives the B support frame 503 to move. By driving the B support frame 503 to move through the B telescopic driving member 513, the height of the flap 200 and the positioning frame 300 can be effectively adjusted, that is, the height of the livestock can be effectively adjusted. Similarly, the flap 200 can also be further moved away from the side wall of the channel 101 during the rotation process.

[0056] In one embodiment of the present invention, the positioning frame 300 includes a clamping portion 302 and a connecting portion 303. The clamping portion 302 includes two C-shaped rods, one end of the two C-shaped rods are respectively fixedly connected to the connecting portion 303, and one side of the connecting portion 303 is fixedly connected to the A rotating shaft 301. The C-shaped rod of the clamping portion 302 is used to position the side wall and abdomen of the livestock, thereby limiting the movement of the livestock, so as to facilitate turning the livestock over.

[0057] In one embodiment of the present invention, the positioning frame 300 further includes two handles 304 , one end of each of which is fixedly connected to the connecting portion 303 , so that the user can push and pull the positioning frame 300 through the handles 304 to rotate the positioning frame 300 around the axis of the A rotation shaft 301 .

[0058] In one embodiment of the present invention, the outside of the C-shaped rod is covered with a soft pad to reduce the discomfort of the livestock when the livestock is limited and fixed.

[0059] In one embodiment of the present invention, the side wall of the main frame 100 away from the flap 200 is arranged in an inclined shape. When the flap 200 is in a vertical state, the distance between the top end of the side wall and the flap 200 is greater than the distance between the bottom end of the side wall and the flap 200. The upper space of the channel 101 is large, so that the positioning frame 300 has sufficient rotation space, and when the animal is turned over, the animal's legs can be further prevented from touching the main frame 100.

[0060] In one embodiment of the present invention, a corresponding control unit can be set for use. The control unit can select any controller to be connected to the electrical components in the present application, so as to control the opening and closing operation of each electrical component. This part is the prior art. Here, a single-chip microcomputer can be provided as a control unit for display. The single-chip microcomputer in this embodiment is a typical embedded microcontroller (Microcontroller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption.

[0061] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
