Description

Technical Field

[0001] This utility model relates to the field of sheep pen technology, and in particular to a sheep pen door that prevents escape. Background Technology

[0002] Sheep pens are enclosed facilities used for raising sheep and play an important role in animal husbandry. As a key link in protecting and managing sheep flocks, the design and quality of sheep pen doors have a decisive impact on overall safety and management efficiency. Especially in the two core stages of daily grazing and nighttime rest, existing swing-type sheep pen doors have gradually revealed a series of obvious limitations and technical problems in preventing sheep from escaping.

[0003] Specifically, existing sheep pen designs are inconvenient for restricting the doors. Traditional sheep pen doors use a swing-open design, which is easily broken open by sheep. This not only risks escape but also increases the difficulty of manual supervision, leading to insufficient safety. Traditional sheep pen door designs face significant problems in practical use, including inconvenience in operation, low efficiency, and difficulty in effectively controlling sheep entry and exit. These problems directly reduce management efficiency, increase labor intensity, and fail to meet the demands of modern farming for high efficiency and safety. Furthermore, the lack of security in sheep pen doors can pose potential risks to the overall operation of the farm, such as disease transmission or property damage. Therefore, given the numerous shortcomings of existing technologies, we urgently need an innovative sheep pen door design solution to address these challenges. Utility Model Content

[0004] The purpose of this invention is to provide a sheep pen door that prevents escape, solving the problem that existing sheep pen doors use a swing-open design, which is easily broken open by sheep. This not only poses a risk of escape but also makes it difficult to effectively control the opening and closing of the door, directly leading to reduced management efficiency and increased labor intensity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An escape-proof sheep pen door includes a frame, a door panel slidably connected to the inner side of the frame, and toothed plates fixedly connected to both sides of the door panel. Support rods are rotatably connected to both sides of the inner side of the frame. Gears are sleeved on one end of each support rod, and the two gears mesh with the two toothed plates respectively. The other ends of each support rod penetrate the side wall of the frame through bearing sleeves, and ratchet wheels are sleeved on one end of each support rod. Pads are rotatably connected to both sides of the frame, and the two pads engage with the two ratchet wheels respectively.

[0007] Preferably, side rods are fixedly connected to both sides of the two frames, and one end of each of the two pawls is rotatably connected to one end of the two side rods respectively through a torsion spring shaft.

[0008] Preferably, side plates are fixedly connected to both sides of the frame, and a locking block is fixedly connected to one side of each of the two pawls, and a locking seat for use with the locking block is fixedly connected to the bottom of each of the two side plates.

[0009] Preferably, sliders are fixedly connected to both sides of the door panel, and both sliders are slidably connected to the inner wall of the frame through a groove.

[0010] Preferably, a counterweight is fixedly connected to the bottom of the door panel, and a handle is fixedly connected to one side of the lower part of the door panel.

[0011] Preferably, mounting plates are fixedly connected to both sides of the frame.

[0012] This utility model has the following beneficial effects:

[0013] This invention effectively solves the problem of inconvenient door-locking in existing sheep pens by using a combination of a toothed plate, gears, ratchet, and pawl. When the door is closed, even if impacted by the sheep, the pawl effectively prevents the ratchet from reversing, thus ensuring the door will not be accidentally opened and greatly reducing the risk of sheep escaping. This not only avoids the risks of disease transmission or property damage that may result from escaped sheep, but also provides a safer and more reliable guarantee for the development of modern animal husbandry, meeting the demands for efficient and safe production.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-6 An escape-proof sheep pen door includes a frame 1, with a door panel 3 slidably connected to the inner side of the frame 1. The door panel 3 slides up and down within the frame 1 to achieve the opening and closing function. The door panel 3 is equipped with toothed plates 6 on both sides, which allow it to interact with gears 8 and control the movement of the door panel 3. The toothed plates 6 are fixedly connected to both sides of the door panel 3. The toothed design of the toothed plates 6 allows them to mesh with gears 8. When the door panel 3 moves, the toothed plates 6 drive the gears 8 to rotate, thereby driving the support rods 7 and their ratchet 11 to rotate. The support rods 7 are rotatably connected to both sides of the inner side of the frame 1. The two ends are respectively connected to the two sides of the frame 1, and a gear 8 is sleeved on one end and a ratchet 11 is sleeved on the other end. The function of the support rods 7 is to transmit the movement of the toothed plates 6 to the ratchet 11, and at the same time support the operation of the entire mechanical linkage mechanism. Gears 8 are sleeved on one end of the two support rods 7, and the two gears 8 are meshed with the two toothed plates 6 respectively. The other ends of the two support rods 7 pass through the side wall of the frame 1 through bearing sleeves, and ratchet 11 is sleeved on one end of the two support rods 7 and installed on one end of the support rods 7 to cooperate with the pawl 14. The design of the ratchet 11 allows it to rotate freely in one direction, but is locked in the opposite direction by the pawl 14, thereby preventing the door panel 3 from opening accidentally. Pawls 14 are rotatably connected to both sides of the frame 1. The pawls 14 are located on both sides of the frame 1 and restrict the reverse rotation of the load-bearing rod 7 by cooperating with the ratchet 11. The pawls 14 can be manually moved when necessary to release the lock on the ratchet 11, allowing the door panel 3 to move upward and open. The two pawls 14 are used in cooperation with the two ratchet 11 respectively.

[0024] When using an escape-proof sheepfold gate, the user first slides the gate panel 3 down along the inner side of the frame 1 to close it. As the gate panel 3 moves down, the locking plates 6 fixed on both sides also move, and drive the support rod 7 to rotate through the gears 8 that mesh with them. Since the pawl 14 does not restrict the rotation of the ratchet 11 at this time, the entire system can smoothly complete the closing action. Once it is necessary to open the gate panel 3 for grazing or other operations, the user only needs to manually move the pawl 14 to disengage it from the ratchet 11, and then pull the gate panel 3 up. During this process, although the locking plates 6 attempt to drive the gears 8 to rotate, since the pawl 14 has released the lock on the ratchet 11, the gears 8 on the support rod 7 can no longer prevent the gate panel 3 from moving up, thus successfully opening the gate.

[0025] Furthermore, side rods 10 are fixedly connected to both sides of the two frames 1, and one end of each pawl 14 is rotatably connected to one end of each side rod 10 via a torsion spring shaft. When the user moves the pawl 14 to disengage it from the ratchet 11, the torsion spring shaft provides a restoring force, causing the pawl 14 to automatically return to its initial position after being released, and re-engage with the ratchet 11. This ensures the stability and reliability of the pawl 14 in daily use, reduces the frequency of manual adjustments, and achieves the effect of improving operational convenience and system stability.

[0026] Furthermore, side plates 9 are fixedly connected to both sides of the frame 1, and a locking block 16 is fixedly connected to one side of each of the two pawls 14. A locking seat 15 for use with the locking block 16 is fixedly connected to the bottom of each of the two side plates 9. When the pawl 14 is moved, the locking block 16 on it will cooperate with the locking seat 15 at the bottom of the side plate 9 to form a stable locking state, preventing the pawl 14 from accidentally loosening under non-human operation, so as to release the ratchet 11 from the limit.

[0027] Furthermore, sliders 4 are fixedly connected to both sides of the door panel 3, and both sliders 4 are slidably connected to the inner wall of the frame 1 through the slide groove 5. When the door panel 3 slides up and down inside the frame 1, the sliders 4 move along the slide groove 5, ensuring that the movement trajectory of the door panel 3 is stable and accurate, and avoiding operational difficulties caused by the door panel 3 shifting or getting stuck.

[0028] Furthermore, a counterweight 12 is fixedly connected to the bottom of the door panel 3, and a handle 13 is fixedly connected to one side of the lower part of the door panel 3. The counterweight 12 can improve the stability of the door panel 3.

[0029] Furthermore, mounting plates 2 are fixedly connected to both sides of the frame 1. The mounting plates 2 can firmly fix the entire sheep pen gate to the sheep pen fence, ensuring that the frame 1 will not loosen or tilt due to external impact or long-term use during use.

[0030] In summary:

[0031] When using an escape-proof sheep pen door, the user first slides the door panel 3 down along the inner side of the frame 1 to close it. As the door panel 3 moves down, the locking plates 6 fixed on both sides also move, and drive the bearing rod 7 to rotate through the gear 8 meshing with them. Since the pawl 14 does not restrict the rotation of the ratchet 11 at this time, the entire system can smoothly complete the closing action. Specifically, side rods 10 are fixedly connected to both sides of the two frames 1, and one end of each pawl 14 is rotatably connected to one end of each side rod 10 through a torsion spring shaft. In this way, when the user moves the pawl 14 to disengage it from the ratchet 11, the torsion spring shaft can provide a rebound force, so that the pawl 14 automatically returns to its initial position after being released, and re-engages with the ratchet 11, ensuring the stability and reliability of daily use. Side plates 9 are fixedly connected to both sides of the frame 1, and a locking block 16 is fixedly connected to one side of each of the two pawls 14. A locking seat 15 for use with the locking block 16 is fixedly connected to the bottom of each of the two side plates 9. When the pawl 14 is moved, the locking block 16 on it engages with the locking seat 15 at the bottom of the side plate 9, forming a stable locking state to prevent the pawl 14 from accidentally disengaging without human intervention, thus ensuring system safety. Furthermore, sliders 4 are fixedly connected to both sides of the door panel 3, and both sliders 4 are slidably connected to the inner wall of the frame 1 via a sliding groove 5. This ensures that the movement trajectory of the door panel 3 when sliding up and down inside the frame 1 is smooth and precise, avoiding operational difficulties caused by offset or jamming. When it is necessary to open the door panel 3 for grazing or other operations, the user only needs to manually move the pawl 14 to disengage it from the ratchet 11, and then pull up the door panel 3. During this process, although the toothed plate 6 attempts to drive the gear 8 to rotate, the pawl 14 has released its lock on the ratchet 11, preventing the gear 8 on the support rod 7 from continuing to prevent the door panel 3 from moving upward, thus successfully opening the door. Furthermore, a counterweight 12 is fixedly connected to the bottom of the door panel 3, and a handle 13 is fixedly connected to one side of the lower part of the door panel 3. The counterweight 12 improves the stability of the door panel 3, while the handle 13 facilitates the user's application of force, simplifying the operation. Finally, mounting plates 2 are fixedly connected to both sides of the frame 1. These mounting plates 2 securely fix the entire sheep pen door to the sheep pen fence, ensuring that the frame 1 will not loosen or tilt due to external impact or long-term use. This design achieves several beneficial effects: the side rod 10, torsion spring pivot, and pawl 14 improve operational convenience and system stability; the side plate 9, locking block 16, and locking seat 15 enhance the safety and reliability of the door panel 3's limiting function; the slider 4 and slide groove 5 improve the overall structural durability and ease of use; the counterweight 12 and handle 13 optimize the operating experience and improve management efficiency; and the mounting plate 2 enhances product safety and reliability.In conclusion, this sheep pen door not only effectively solves the problem that traditional swing-type sheep pen doors are easily knocked open by sheep, but also greatly improves work efficiency and safety in the breeding process.
