A foldable mobile chicken coop frame

Abstract

This utility model relates to the field of chicken coop frame technology and discloses a foldable mobile chicken coop frame, including a base. Two reinforcing plates are fixedly installed in the middle of the base. Folding rods are symmetrically and rotatably installed on both sides of the base. Universal wheels are fixedly installed on both sides of the bottom of the folding rods. By setting the folding rods to rotate relative to the base around the pins, the universal wheels on both sides of the bottom can be driven to rotate synchronously and folded and stored to the bottom sides of the base, so that the bottom of the base forms a relatively flat shape, avoiding the obstruction caused by the protruding universal wheels when carrying. At the same time, the two movable rods are unfolded so that their other ends move into the two rectangular slots. The limiting rod in the locking assembly passes through the rectangular slots upward under the action of the return spring and inserts into the positioning hole of the movable rod, effectively limiting the folding rods in the folded state, preventing the folding rods from being accidentally unfolded or the universal wheels from shaking due to external forces during transportation, and ensuring the stability of the folded form.

Description

Technical Field

[0001] This utility model relates to the field of chicken coop frame technology, and in particular to a foldable and mobile chicken coop frame. Background Technology

[0002] In poultry farming, chicken coops are the core habitat for chickens, and their structural rationality directly affects farming efficiency and management convenience. Traditional chicken coops mostly adopt fixed structures, such as brick-concrete walls with wooden or metal roofs. While such structures can provide relatively stable habitats for chickens, they have significant limitations: high construction and demolition costs, and inability to flexibly adjust their location according to farming needs. If a change of farming area is required, the original chicken coop must be demolished and rebuilt on a large scale, resulting in resource waste. Therefore, foldable mobile chicken coops have gradually become a research and development hotspot in the industry. These chicken coops improve the ease of construction and transportation flexibility through the folding design of the frame structure. Through hinge connections and telescopic structures, the frame can be folded into a compact form when not in use, significantly reducing the space occupied for transportation and storage, and meeting the needs of "build as needed and move when not in use" in small-scale farming scenarios.

[0003] However, to facilitate the easy movement of chicken coops, most products install casters at the bottom of the frame. On the one hand, when the frame is folded, the casters cannot be folded, resulting in protruding parts in the folded chicken coop, which are prone to bumps and knocks during transportation or have poor stability when neatly stacked. On the other hand, even if a few products achieve folding of both the casters and the frame through a simple structure, due to the lack of a reliable limiting mechanism, when the chicken coop is lifted by the side handle, the casters are prone to free rotation and displacement due to gravity or external forces, resulting in a loose folded frame, increasing the difficulty of carrying and reducing convenience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foldable mobile chicken coop frame.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foldable mobile chicken coop frame, including a base, two reinforcing plates fixedly installed in the middle of the base, folding rods symmetrically and rotatably installed on both sides of the base, universal wheels fixedly installed on both sides of the bottom of the folding rods, hidden grooves opened on the inner side of the folding rods, and two sets of locking components symmetrically provided on both sides of the two reinforcing plates.

[0006] The locking assembly includes two rectangular slots, which are formed on the surface of the reinforcing plate near the caster wheel. Two concave seats are fixedly installed at the bottom of the reinforcing plate. A driving member is hinged to the inner side of each of the two concave seats. A limiting rod is hinged to the side of the driving member. The limiting rod passes through the interior of the rectangular slot.

[0007] Two sets of fixing plates are fixedly installed at the bottom of the folding rod and inside the hidden groove. Each set of fixing plates has two plates, and each of the two fixing plates is hinged with a movable rod. The other end of the movable rod is provided with a positioning hole, which is adapted to the limiting rod.

[0008] Preferably, a first shaft is fixedly installed at one end of the drive component inside the concave seat, and the two sides of the first shaft are rotatably installed on the inner wall of the concave seat. A pressing plate is fixedly installed on the side of the drive component near the first shaft.

[0009] Preferably, a return spring is fixedly installed at the upper end of the pressing plate, and the other end of the return spring is fixedly installed at the bottom of the reinforcing plate.

[0010] Preferably, a second shaft is fixedly installed at the bottom of the limiting rod, and both ends of the second shaft are rotatably installed on the inner wall of the end of the driving component away from the pressing plate.

[0011] Preferably, a third shaft is fixedly installed at one end of the movable rod near the fixed plate, and the two ends of the third shaft are rotatably installed between the two fixed plates.

[0012] Preferably, two limiting plates are fixedly installed at each of the four bottom corners of the base. The two limiting plates are located on the side and top of the corner of the base, respectively, and limit the folding rod in the folded or unfolded state.

[0013] Preferably, a folding frame is installed on the upper end of the base, a handle is fixedly installed on the side of the base, and pins are fixedly installed on both sides of the folding rod. The two ends of the folding rod are rotatably installed on both sides of the base through the pins.

[0014] Preferably, the length of the movable rod is adapted to the length of the hidden groove, the friction at the hinge point of the third shaft forms damping, and when the movable rod rotates and is stored in the hidden groove, the side wall of the movable rod fits against the inner wall of the hidden groove, and is stably hidden under the damping effect to avoid shaking.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By setting the folding rod to rotate relative to the base around the pin, the universal wheels on both sides of the bottom can be rotated synchronously and folded to the bottom sides of the base, making the bottom of the base relatively flat and avoiding the obstruction caused by the protruding universal wheels when carrying. At the same time, unfolding the two movable rods allows their other ends to move into the two rectangular slots. The limiting rod in the locking assembly passes through the rectangular slots and inserts into the positioning hole of the movable rod under the action of the return spring, effectively limiting the folding rod in the folded state and preventing the folding rod from being accidentally unfolded or the universal wheels from shaking due to external force during transportation, thus ensuring the stability of the folded form.

[0017] 2. By setting two movable rods at the bottom of the folding rod and inside the hidden groove on its side, the two sets of movable rods cooperate with the locking components at the corresponding positions. When the folding rod is unfolded, the movable rod rotates out from the hidden groove and achieves rigid support of the folding rod by locking it with the rectangular groove through the limit rod. When the folding rod is folded, the movable rod is stored in the hidden groove and locked by the limit rod. It can play a reliable fixing role in both the unfolded and folded states of the folding rod, improve the structural stability of the chicken coop frame in different usage scenarios, and prevent the frame from deforming due to loose connections.

[0018] 3. By setting up a linkage structure between the locking component's drive unit, limit rod, and return spring, pressing the press plate compresses the return spring, causing the drive unit to rotate around the first shaft and pull the limit rod away from the positioning hole via the second shaft, thus releasing the lock. After releasing the press plate, the return spring resets and pushes the drive unit to rotate in the opposite direction, automatically inserting the limit rod into the positioning hole to complete the lock. This series of operations enables the rapid unfolding or folding of the casters without the need for complex tools, improving the folding efficiency and ease of operation of the chicken coop frame and adapting to the needs of frequently moving breeding scenarios.

[0030] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0032] Example: Reference Figures 1-6 A foldable mobile chicken coop frame includes a base 1, two reinforcing plates 103 fixedly installed in the middle of the base 1, folding rods 2 symmetrically rotated on both sides of the base 1, universal wheels 201 fixedly installed on both sides of the bottom of the folding rods 2, hidden grooves 202 are opened on the inner side of the folding rods 2, and two sets of locking components 3 are symmetrically provided on both sides of the two reinforcing plates 103.

[0033] The locking assembly 3 includes two rectangular slots 301, which are formed on the side surface of the reinforcing plate 103 near the universal wheel 201. Two concave seats 302 are fixedly installed at the bottom of the reinforcing plate 103. A driving member 303 is hinged to the inner side of each of the two concave seats 302. A limiting rod 306 is hinged to the side of the driving member 303. The limiting rod 306 passes through the interior of the rectangular slot 301.

[0034] Two sets of fixing plates 4 are fixedly installed at the bottom of the folding rod 2 and inside the hidden groove 202. There are two fixing plates 4 in each set, and the two fixing plates 4 are hinged with movable rods 401 inside. The other end of the movable rods 401 is provided with positioning holes 403, which are adapted to the limiting rods 306.

[0035] Specifically: In practical applications, the folding rod 2 can switch between unfolded and folded states by rotating with the base 1. The universal wheels 201 at its bottom facilitate the movement of the frame. In the locking assembly 3, the driving component 303, as a transmission component, can drive the limiting rod 306 to move. The limiting rod 306 locks the movable rod 401 by adapting to the positioning hole 403. The movable rod 401 can cooperate with the reinforcing plate 103 when unfolded by rotating on its own. The positioning hole 403 at its end and the limiting rod 306 form a locking structure to ensure that the folding rod 2 remains stable in the specified state.

[0036] By rotating the folding rod 2, it can be unfolded or folded relative to the base 1. The movable rod 401 rotates out of or into the hidden groove 202 as the folding rod 2 rotates. When the movable rod 401 rotates to the position corresponding to the reinforcing plate 103, the positioning hole 403 at its end aligns with the rectangular groove 301. At this time, the driving component 303 drives the limiting rod 306 to pass through the rectangular groove 301 and insert into the positioning hole 403, thereby locking the movable rod 401 and fixing the folding rod 2 in the current state. This ensures the structural stability of the frame during use or transportation. Through the coordinated cooperation of various components, the frame can be conveniently folded and reliably locked.

[0037] A first shaft 304 is fixedly installed on one end of the drive component 303 inside the concave seat 302. The two sides of the first shaft 304 are rotatably installed on the inner wall of the concave seat 302. A pressing plate 305 is fixedly installed on the side of the drive component 303 near the first shaft 304. A return spring 308 is fixedly installed on the upper end of the pressing plate 305. The other end of the return spring 308 is fixedly installed on the bottom of the reinforcing plate 103. A second shaft 307 is fixedly installed on the bottom of the limiting rod 306. The two ends of the second shaft 307 are rotatably installed on the inner wall of the end of the drive component 303 away from the pressing plate 305.

[0038] Specifically: The pressing plate 305 is designed to allow the operator to drive the drive component 303 to rotate around the first shaft 304 by pressing. The reset spring 308 connects the pressing plate 305 to the bottom of the reinforcing plate 103. When the pressing plate 305 is subjected to external force, it can generate elastic deformation. After the external force disappears, it releases the elastic force to push the pressing plate 305 to drive the drive component 303 to reset, providing power for the automatic locking of the limit rod 306. This allows the limit rod 306 to move up and down with the rotation of the drive component 303, ensuring that the limit rod 306 can accurately correspond to the positioning hole 403 to complete the insertion or disengagement action.

[0039] By pressing the pressing plate 305, the driving component 303 rotates around the first shaft 304 and compresses the return spring 308. At the same time, the second shaft 307 drives the limiting rod 306 to descend synchronously, realizing the unlocking action of the limiting rod 306 disengaging from the positioning hole 403. When the pressing plate 305 is released, the return spring 308 restores its deformation and pushes the pressing plate 305 to drive the driving component 303 to rotate in the opposite direction around the first shaft 304. The second shaft 307 then drives the limiting rod 306 to rise, so that the limiting rod 306 inserts into the positioning hole 403 to complete the locking. This realizes the quick unlocking and automatic locking of the locking component 3, ensuring the reliability and ease of operation of the fixed state of the movable rod 401 and the folding rod 2.

[0040] The movable rod 401 is fixedly installed with a third shaft 402 at one end near the fixed plate 4. The two ends of the third shaft 402 are rotatably installed between the two fixed plates 4. Two limiting plates 203 are fixedly installed at the four corners of the bottom of the base 1. The two limiting plates 203 are located on the side and the top of the corner of the base 1, respectively, and limit the folding rod 2 in the folded or unfolded state.

[0041] A folding frame 101 is installed on the upper end of the base 1, and a handle 102 is fixedly installed on the side of the base 1. Pins 204 are fixedly installed on both sides of the folding rod 2. The two ends of the folding rod 2 are rotatably installed on both sides of the base 1 through the pins 204. The length of the movable rod 401 is adapted to the length of the hidden groove 202. The friction of the hinge point of the third shaft 402 forms damping. When the movable rod 401 rotates and is stored in the hidden groove 202, the side wall of the movable rod 401 is in contact with the inner wall of the hidden groove 202, and is stably hidden under the action of damping to avoid shaking.

[0042] Specifically: The limiting plates 203 are located on the side and top of the corner of the base 1, which can block the folding rod 2 when it is rotated to the unfolded or folded state, limit the excessive rotation of the folding rod 2, and ensure that the folding rod 2 remains stable in the target position. The handle 102 makes it easy for the operator to lift or push the frame. When the movable rod 401 is stored in the hidden groove 202, its side wall fits against the inner wall of the hidden groove 202 to generate a guiding effect. The damping force can counteract the rotation tendency generated by the gravity of the movable rod 401 itself, so that the movable rod 401 is stably hidden in the hidden groove 202 without shaking.

[0043] Through the cooperation of pin 204 and folding rod 2, folding rod 2 can rotate around base 1 to unfold and fold. Movable rod 401 moves synchronously with folding rod 2 under the support of the third shaft rod 402. When folding rod 2 rotates to the target position, limiting plate 203 limits it. At this time, movable rod 401 can either rotate out to cooperate with locking component 3 to lock, or be stored in hidden groove 202 and remain stable under damping. With handle 102, the frame can be moved and transported conveniently. The coordinated action of each component not only ensures the structural stability of the frame in use and storage, but also improves the ease of operation.

[0044] The working principle of this utility model is as follows: In specific use, the chicken coop is first opened or folded according to the breeding needs. When the chicken coop needs to be opened for use, the folded frame is placed in the designated position by using the handle 102. The pressing plate 305 at the bottom of the reinforcing plate 103 is pressed. The pressing plate 305 rotates downward around the first shaft 304 and compresses the return spring 308. At this time, the driving component 303 forms a lever structure with the first shaft 304 as the fulcrum. Its other end drives the limiting rod 306 to move downward through the second shaft 307, so that the limiting rod 306 disengages from the positioning hole 403 of the movable rod 401 and releases the lock on the movable rod 401.

[0045] Subsequently, the folding rod 2 is rotated to both sides. The folding rod 2 rotates relative to the base 1 around the pin 204, causing the universal wheel 201 at the bottom to gradually contact the ground. At the same time, the movable rod 401 in the hidden groove 202 is pulled out of the hidden groove 202 around the third shaft 402 under the pull of the folding rod 2. When the folding rod 2 rotates to a horizontally unfolded state with the base 1, the limiting plates 203 at the four corners of the bottom of the base 1 block the folding rod 2, restricting its continued rotation. At this time, the movable rod 401 rotates to align with the rectangular groove 301 of the reinforcing plate 103. The pressing plate 305 is released, and the return spring 308 restores its deformation, pushing the pressing plate 305 to rotate upward. The driving component 303 rotates in the opposite direction and drives the limiting rod 306 to move upward through the second shaft rod 307. The limiting rod 306 passes through the rectangular groove 301 and is inserted into the positioning hole 403 of the movable rod 401, completing the locking of the movable rod 401, thereby fixing the folding rod 2 in the unfolded position. The universal wheel 201 stably supports the entire chicken coop. At this time, the chicken coop can be pushed by the handle 102, and the position can be adjusted by using the universal wheel 201.

[0046] When the chicken coop needs to be folded for stacking or transport, press the pressing plate 305 again to disengage the limiting rod 306 from the positioning hole 403, release the lock of the movable rod 401, rotate the folding rod 2 inward, and the movable rod 401 rotates around the third shaft 402 and gradually retracts into the hidden groove 202. The friction of the hinge point of the third shaft 402 forms damping, which, together with the fit between the side wall of the movable rod 401 and the inner wall of the hidden groove 202, makes the movable rod 401 stably retracted without shaking.

[0047] The folding rod 2 continues to rotate, causing the caster wheel 201 to flip upwards until the folding rod 2 is in contact with the base 1. At this time, another set of limiting plates 203 at the bottom of the base 1 limits the folding rod 2 to prevent it from rotating excessively. After releasing the pressing plate 305, the limiting rod 306 is inserted into the positioning hole 403 of the movable rod 401 again, locking the folding rod 2 in the folded state. The caster wheel 201 is stored on both sides of the bottom of the base 1, making the bottom of the base 1 relatively flat. The chicken coop can be easily lifted and carried by the handle 102, avoiding the shaking of parts during the folding process.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
