Description

Technical Field

[0001] This utility model relates to the field of restraint technology, specifically to a cattle restraint. Background Technology

[0002] A restraint frame is a device for securing livestock, usually made of steel. It is mainly used in the livestock industry to ensure the health and productivity of the animals being raised. Its purpose is to facilitate veterinarians in treating and observing the condition of sick livestock.

[0003] In practical use, most restraint frames used by veterinarians employ motors to control the position of components within the frame. However, the imprecise control of these motors can cause the frame to compress the animal's neck or other parts, making the animal more agitated and hindering subsequent treatments such as injections. Furthermore, the animal's struggles can put pressure on the motor, leading to damage and shortening the frame's lifespan. Therefore, a new cattle restraint frame was designed to reduce the production cost of existing restraint frames, while also providing greater comfort for the animal and extending the frame's lifespan.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figures 1 to 3This utility model provides a technical solution: a cattle restraint frame, including a front frame 1, side frames 4, and a rear frame 7. The front frame 1 and the rear frame 7 are installed at both ends of the two side frames 4, which are symmetrically distributed. A crossbeam 2 and a guide groove 3 are fixed on the top wall of the front frame 1. The crossbeam 2 and the guide groove 3 are distributed front and rear. A front door guide rail 6 is connected below the crossbeam 2. A sliding seat 61 slides on the front door guide rail 6. A left front door 11 and a right front door 12 are connected below the front door guide rail 6 through the sliding seat 61. The left front door 11 and the right front door 12 move left and right along the front door guide rail 6 together with the sliding seat 61. A rack and pinion slider fixing plate is connected to the upper end of the right front door 12. 33. A rack and slider 32 is connected to the side of the rack and slider fixing plate 33. The rack and slider 32 slides in the guide groove 3. A movable rack 31 is connected to the lower end of the rack and slider 32. A gear fixing plate 13 is fixed to the upper end of the left front door 11. A rotating shaft 35 is connected to the gear fixing plate 13 through a bearing. A first gear 34 and a second gear 36 are connected to the rotating shaft 35. The first gear 34 and the second gear 36 are distributed front and rear. The first gear 34 meshes with the movable rack 31. A rack fixing block 38 is also fixed between the crossbeam 2 and the guide groove 3. A fixed rack 37 is connected to the lower end of the rack fixing block 38. The fixed rack 37 meshes with the second gear 36. An operating mechanism is connected to one side of the right front door 12. This mechanism controls the left and right movement of the right front door 12. Moving the right front door 12 outwards via the operating mechanism drives the rack and pinion slider fixing plate 33, further causing the rack and pinion slider 32 and the movable rack 31 to move left and right. The movable rack 31 meshes with the first gear 34, which rotates clockwise, causing the first gear 34, the rotating shaft 35, and the second gear 36 to rotate. The second gear 36 meshes with the fixed rack 37, which is fixed to the rack fixing block 38. The clockwise rotation of the second gear 36 allows it to move along the fixed... The rack 37 moves outward, further causing the gear fixing plate and the left front door to move together. This causes the right front door 12 and the left front door 11 to move in opposite directions, opening the front door. In summary, the movement of the right front door 12 on one side drives the movable rack 31 to move. Through the meshing of the first gear 34 with the movable rack 31 and the meshing of the second gear 36 with the fixed rack 37, the left front door 11 on the other side moves in the opposite direction to the right front door 12. This facilitates the movement of the left front door 11 and the right front door 12 together, thus opening the door. This structure is easy to operate; controlling one side of the door allows the other side to move in the opposite direction, thereby opening or closing the front door.

[0024] A rotating shaft connecting seat 21 is fixed to one end of the crossbeam 2, and an upper connecting pipe 5 is also fixed to the side frame 4. A rotating shaft connecting seat 21 is also fixed to the upper connecting pipe 5. The operating mechanism includes a rotating shaft 22, which is rotatably connected between the two rotating shaft connecting seats 21. A handle 23 is connected to the rotating shaft 22. The rotating shaft 22 is connected to the right front door 12 through a door linkage 28. By swinging the handle 23, the rotating shaft 22 is controlled to rotate, which further enables the door linkage 28 to drive the right front door 12 to move left and right, thus facilitating the manual opening of the right front door 12.

[0025] like Figure 2 and 4 As shown, a locking gear 24 is fixed on the surface of the rotating shaft connecting seat 21. A handle 25 is rotatably connected to the handle 23. A gear connecting rod 26 is hinged to the other end of the handle 25. A plug sleeve 27 is also fixed to the upper end of the handle 23. The gear connecting rod 26 moves up and down in the plug sleeve 27. The gear connecting rod 26 presses against the locking gear 24, limiting the angle of the handle 23. By squeezing the handle 25, the handle 25 drives the gear connecting rod 26 to move up and down in the plug sleeve 27. When the gear connecting rod 26 presses against the locking gear 24, the positions of the handle 23 and the rotating shaft 22 are fixed and cannot rotate, further locking the position of the right front door 12. When the handle 25 is rotated, the gear connecting rod 26 no longer presses against the locking gear 24, and the handle 23 is no longer locked, allowing it to swing freely and adjust the angle of the rotating shaft 22, further facilitating the control of the opening position of the right front door 12.

[0026] The number of teeth on the first gear 34 is twice the number of teeth on the second gear 36, and the outer diameter of the first gear 34 is 1.95 times the outer diameter of the second gear 36. The two gears rotate concentrically through a rotating shaft, and the force is input and output through the tangential direction of the gear normal. The lever arm of the larger gear is greater than that of the smaller gear, thus achieving the effect of saving effort.

[0027] The side frame 4 is connected by hinges to a first side door 41, a second side door 42, a third side door 43 and a fourth side door 44. The first side door 41 and the second side door 42 are distributed left and right, the first side door 41 and the third side door 43 are distributed up and down, and the second side door 42 and the fourth side door 44 are also distributed up and down.

[0028] like Figure 2 As shown, a rear door 71 slides inside the rear door frame 7. A lower guide wheel 73 is fixed on the top wall of the rear door frame 7. The lower guide wheel 73 is located inside the upper frame of the rear door 71 and fits against the top wall to guide the movement of the rear door 71.

[0029] The rear door 71 is also connected to an upper guide wheel 72 via a baffle 75. The upper guide wheel 72 is located at the upper end of the rear door frame 7, and the lower end of the upper guide wheel 72 is attached to the upper end of the rear door 71, so that the upper end of the upper frame of the rear door 71 and the top wall are guided by the upper guide wheel 72 and the lower guide wheel 73 respectively, making the rear door 71 move more smoothly.

[0030] The rear door 71 is also connected to a rear door handle 74 on its side. By manually dragging the rear door handle 74, the movement of the rear door 71 can be controlled, thereby opening or closing the rear door 71.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
