Description
Technical Field
[0001] The utility model relates to the technical field of breeding cages, in particular to a snap-type cage door. Background Art
[0002] A cage door is installed on the side cage net of a breeding cage, and the opening method of the cage door adopts a sliding door design. In order to prevent the chickens in the breeding cage from pushing open the cage door, a limiting structure needs to be arranged between the cage door and the cage net, so as to increase the opening and closing resistance of the cage door and avoid the chickens accidentally opening the cage door. The existing limiting structure on the cage door is directly arranged on the cage door and adopts a full-metal structure; as Figure 1 shown, the limiting structure includes a protrusion 12 protruding outward from the cross bar of the cage door 1 and a vertical bar 11 arranged on the cage door 1 of another breeding cage; when the breeding cage needs to be opened, the corresponding cage door 1 is pushed, and the protrusion 12 is pressed downward so that the protrusion 12 crosses over the vertical bar 11, thereby realizing the horizontal opening of the cage door 1.
[0003] For the above way of opening the cage door, the operator needs to use a lot of strength to press down the protrusion 12 and cross over the vertical bar 11 to open the cage door 1. Not only is the operation difficult, but people with little strength cannot open the cage door; moreover, the cross bar of the cage door 1 is compressed and deformed for a long time, which is extremely easy to cause the failure of the limiting structure and cannot play the limiting role of the cage door 1; once the limiting structure fails, the entire breeding cage needs to be repaired, and the repair cost and repair difficulty are also relatively large. Content of the Utility Model
[0004] The purpose of the utility model is to provide a snap-type cage door. By arranging a detachable snap on the cage door, the deformation limit of the cross bar of the cage door is replaced by the limit of the snap. The opening and closing of the snap do not require much strength, thereby reducing the opening and closing difficulty of the cage door; at the same time, the snap is easy to replace, reducing the repair cost and repair difficulty.
[0005] To achieve the above purpose, the utility model provides a snap-type cage door, which includes a cage door that can be pushed and pulled left and right and a snap detachably installed on the right side of the cage door; the snap includes a connecting plate extending left and right in a sheet shape, a rotating hook for hooking on the first vertical bar of the cage door is arranged on the left side of the connecting plate; a locking hook for hooking on the second vertical bar of the non-aforementioned cage door is arranged on the right side of the connecting plate; the locking hook includes an elastic sheet with one end connected to the connecting plate and the other end bent backward and left of the connecting plate and capable of elastic deformation. A locking groove in a U-shaped structure for the second vertical bar to be inserted into is formed between the elastic sheet and the connecting plate; a handle extending obliquely backward and right is connected to the end of the elastic sheet; the distance between the first vertical bar and the notch position of the locking groove is less than the distance between the first vertical bar and the second vertical bar; when the handle is pulled forward, the handle pulls the elastic sheet to deform to form an avoidance for the second vertical bar, and the second vertical bar is inserted into or removed from the locking groove.
[0006] After adopting the above structure, by detachably installing a buckle on the cage door, the deformation limit of the cage door cross bar is replaced by the limit of the buckle. When the limit fails, the repair can be completed by replacing the buckle, thus reducing the repair cost and difficulty; by setting a rotary hook on the left side of the buckle, it is convenient to install the buckle on the cage door, improving the installation efficiency; a locking groove for the second vertical rod to be inserted is arranged between the elastic sheet and the connecting plate, and the elastic sheet clamps the second vertical rod. By pulling the elastic sheet to deform with the handle, the second vertical rod is inserted into or removed from the locking groove, realizing the limit or release of the limit of the cage door; the handle adopts the lever principle, which can conveniently pull the elastic sheet to deform, and the operation can be completed without much effort, thus reducing the opening and closing difficulty of the cage door.
[0007] In order to facilitate the production of the buckle and reduce the production cost, the connecting plate and the rotary hook and locking hook thereon are of an integrally formed structure.
[0008] In order to facilitate the installation of the first vertical rod and prevent it from easily coming out, the rotary hook includes a bending part with the right end connected to the connecting plate and the left end bent backward and rightward of the connecting plate. A rotary hole for the first vertical rod to rotate is formed between the bending part and the connecting plate. A through groove for the first vertical rod to be inserted into the rotary hole is arranged between the end of the bending part and the connecting plate, and the width of the through groove is smaller than the diameter of the first vertical rod.
[0009] In order to facilitate the guiding installation of the first vertical rod and at the same time reduce the probability of the buckle directly falling when the first vertical rod comes out of the rotary hook, a guiding plate is arranged at the end of the bending part on one side of the through groove. The guiding plate extends obliquely backward and rightward, and a V-shaped groove is formed between the guiding plate and the connecting plate. The through groove is located at the minimum width position of the V-shaped groove.
[0010] In order to limit the end position of the second vertical rod and prevent the second vertical rod from reaching the bottom of the locking groove, causing the elastic sheet to be unable to avoid the second vertical rod and resulting in the failure of the second vertical rod to be inserted into or removed from the locking groove, a limiting convex block extending towards the elastic sheet is arranged on the connecting plate in the locking groove. The limiting convex block, the elastic sheet and the connecting plate enclose the locking groove.
[0011] In order to prevent the second vertical rod from hitting the limiting convex block, causing serious wear of the limiting convex block, and at the same time, due to the vibration of the breeding cage, the interaction between the second vertical rod and the limiting convex block, resulting in the wear of the limiting convex block and the generation of noise, an elastic layer is arranged at the contact position between the outside of the limiting convex block and the second vertical rod.
[0012] In order to improve the production efficiency of the limiting convex block and the elastic layer, the limiting convex block and the elastic layer are made by two-color injection molding.
[0013] In order to improve the strength of the limiting convex block, the limiting convex block is of a trapezoidal structure, and its long bottom is fixed on the connecting plate.
[0014] In order to improve the strength of the handle and prevent the handle from being deformed when being bent and failing to drive the elastic sheet to deform, reinforcing ribs are provided on the back of the handle.
[0015] In order to reduce the weight of the buckle, the connecting plate also produces a certain deformation when the buckle is pried, so as to assist the second vertical rod to escape from the locking groove, so the connecting plate is a convex structure, and the width of the left side is greater than the width of the right side.
[0016] After adopting the above technical solution, the beneficial effects of the utility model are:
[0017] The utility model discloses a snap-on cage door to solve the technical problems in the prior art that when a cage door with a full metal snap is opened and closed, its limiting structure makes the cage door difficult to open and close, and once the limiting fails, the maintenance difficulty and cost are high. The utility model provides a detachable snap on the cage door, so that the limiting of the snap replaces the deformation limiting of the cage door cross bar, and the snap does not require much force to open and close, thereby reducing the difficulty of opening and closing the cage door; at the same time, the snap is easy to replace, reducing the maintenance cost and difficulty of maintenance.

DETAILED DESCRIPTION
[0026] The utility model is further described below in conjunction with the accompanying drawings.
[0027] The positions involved in this specification are based on the positions of the snap-on cage door of the utility model when it is working normally, and do not limit its positions during storage and transportation. They only represent relative position relationships, not absolute position relationships.
[0028] like Figure 2 , Figure 3 and Figure 4 As shown together, a buckle-type cage door comprises a cage door 1 that can be pushed and pulled left and right and a buckle 2 that is detachably mounted on the right side of the cage door 1. The buckle 2 is mounted at the opening position of the cage door 1. If the opening position of the cage door 1 is on the left side, the buckle 2 can be mounted on the left side of the cage door 1. For the convenience of description, the following description is based on the left-right relationship in the accompanying drawings.
[0029] The buckle 2 includes a connecting plate 21 extending left and right in a sheet shape, and a rotating hook 22 for hooking on the first vertical rod 11 of the cage door 1 is provided on the left side of the connecting plate 21; and a locking hook 23 for hooking on the second vertical rod 3 other than the above-mentioned cage door 1 is provided on the right side of the connecting plate 21. The rotating hook 22 is hooked on the cage door 1, and the locking hook 23 is hooked on the cage door 1 other than the above-mentioned cage door 1, which can be hooked on the side cage net or on the adjacent cage door 1, thereby realizing the position locking of the cage door 1 to avoid accidental opening. In this embodiment, it is chosen to hook on the adjacent cage door 1, that is, the cage door 1 on both sides of the column, so that one buckle can limit the cage doors 1 on both sides of the column at the same time, thereby reducing the number of buckles 2 put into use.
[0030] like Figure 7 As shown, in order to reduce the weight of the buckle 2 and reduce the production cost on the one hand, and to increase the width of the rotating hook 22 on the other hand to ensure its sufficient gripping force and prevent the first vertical rod 11 from slipping out of the rotating hook 22; at the same time, the width of the locking hook 23 is reduced so that when the handle 232 is bent, the connecting plate 21 can also produce a slight deformation to assist the second vertical rod 3 to buckle and slip out of the locking hook 23; therefore, the connecting plate 21 is a convex structure, and the width of its left side is greater than the width of its right side.
[0031] The locking hook 23 includes an elastic sheet 231 connected to the connecting plate 21 at one end and bent to the left rear of the connecting plate 21 at the other end to generate elastic deformation. The elastic sheet 231 and the connecting plate 21 form a U-shaped locking groove for the second vertical rod 3 to be inserted into. The end of the elastic sheet 231 is connected to a handle 232 extending obliquely to the right rear. The distance between the first vertical rod 11 and the notch position of the locking groove is smaller than the distance between the first vertical rod 11 and the second vertical rod 3. The distance between the first vertical rod 11 and the notch position of the locking groove is smaller than the distance between the first vertical rod 11 and the second vertical rod 3, thereby ensuring that the second vertical rod 3 is inserted into the locking groove. The elastic sheet 231 is pulled by the handle 232, causing the elastic sheet 231 to deform, thereby avoiding the second vertical rod 3, causing it to be inserted into or out of the locking groove. The handle 232 adopts the principle of a lever, so that it is more labor-saving when pulling the elastic sheet 231 to deform, and it can be completed without much effort, thereby reducing the difficulty of opening and closing the cage door 1.
[0032] In order to increase the strength of the handle 232 and prevent the handle 232 from being deformed when being bent, which would cause the elastic sheet 231 to be unable to be pulled to deform, a reinforcing rib is provided on the back of the handle 232 .
[0033] like Figure 5 As shown, the first vertical rod 11 is inserted into the rotating hook 22, and the buckle 2 can rotate around the first vertical rod 11. When the cage door 1 needs to be locked, the front side of the connecting plate 21 is pressed; at this time, the second vertical rod 3 is against the handle 232, and generates an interaction force with the handle 232, forcing the handle 232 to drive the elastic sheet 231 to deform, forming a avoidance for the second vertical rod 3, and the second vertical rod 3 is inserted into the locking groove. At this time, the interaction between the second vertical rod 3 and the handle 232 disappears, the elastic sheet 231 is reset, and the second vertical rod 3 cannot escape from the locking groove, forming a locked state.
[0034] When the lock needs to be released, the handle 232 is pulled forward, forcing the handle 232 to drive the elastic sheet 231 to deform, thereby making way for the second vertical rod 3, and the second vertical rod 3 escapes from the locking groove.
[0035] In order to facilitate processing and reduce production costs, the connecting plate 21 and the rotating hook 22 and locking hook 23 thereon are integrally formed. In this embodiment, the material is plastic, preferably nylon; sheet metal materials can also be used in actual applications.
[0036] The rotating hook 22 includes a curved portion 221 whose right end is connected to the connecting plate 21 and whose left end is bent toward the right rear of the connecting plate 21. A rotating hole for the first vertical rod 11 to rotate is formed between the curved portion 221 and the connecting plate 21. A through slot 222 for the first vertical rod 11 to be inserted is provided between the end of the curved portion 221 and the connecting plate 21. The width of the through slot 222 is smaller than the diameter of the first vertical rod 11. By making the width of the through slot 222 smaller than the diameter of the first vertical rod 11, it is reduced that the first vertical rod 11 easily escapes from the rotating hole.
[0037] The end of the curved portion 221 is located on one side of the through groove 222 and is provided with a guide plate 223, which is inclined to the right rear; a V-shaped groove is formed between the guide plate 223 and the connecting plate 21, and the through groove 222 is located at the minimum width position of the V-shaped groove. By providing the guide plate 223, it is convenient to guide the first vertical rod 11 and to install the first vertical rod 11. At the same time, the V-shaped groove is provided, so that when the first vertical rod 11 is disengaged from the rotating hole, it will not fall directly under the action of the V-shaped groove, so that it is convenient for the staff to reinstall it.
[0038] Furthermore, in order to further reduce the difficulty of pulling the elastic sheet 231, the deformation length of the elastic sheet 231 can be increased to ensure sufficient deformation. However, if only the length of the elastic sheet 231 is increased, the depth of the locking groove will be too deep. If the second vertical rod 3 is against the bottom of the locking groove at this time, the second vertical rod 3 cannot be disengaged from the locking groove when the handle 232 is moved. Therefore, a limiting protrusion 211 extending in the direction of the elastic sheet 231 is provided on the connecting plate 21 in the locking groove, and the limiting protrusion 211, the elastic sheet 231 and the connecting plate 21 form a locking groove. The limiting protrusion 211 limits the depth of the locking groove, limits the terminal position of the second vertical rod 3, and prevents it from penetrating too deeply into the end of the elastic sheet 231, causing it to be unable to unlock. At the same time, the lengthened elastic sheet 231 ensures sufficient deformation, so that the second vertical rod 3 can be more easily disengaged, which is more labor-saving.
[0039] The limiting protrusion 211 is a trapezoidal structure, and its long bottom is fixed on the connecting plate 21 , thereby increasing the contact area between its bottom and the connecting plate 21 and improving its strength.
[0040] To avoid the second vertical rod 3 hitting the limit bump 211, which may cause wear of the limit bump 211, and at the same time, after the second vertical rod 3 is inserted into the locking groove, due to the shaking of the breeding cage, frequent collisions between the second vertical rod 3 and the limit bump 211 are likely to occur, resulting in noise and wear. Therefore, an elastic layer is provided at the contact position between the outer side of the limit bump 211 and the second vertical rod 3. The elastic layer can be a rubber layer coated on the outer side of the limit bump 211 by gluing or by other composite methods. In this embodiment, to improve production efficiency, it is preferably that the limit bump 211 and the elastic layer are formed by two-color injection molding. The limit bump 211 is injection molded with plastic of the same material as the connecting plate 21. In this embodiment, the material is PA66, and the elastic layer is injection molded with TPE / TPU material; the elastic layer forms a certain buffering effect, which can relieve the impact force and reduce the frictional noise at the same time.
[0041] As Figure 5 and Figure 6 collectively shown, the installation steps of a snap-type cage door of the present utility model are as follows:
[0042] When limit needs to be achieved, pull the cage door 1 to the rightmost side. At this time, the opening of the cage door 1 is closed. Rotate the connecting plate 21, and the connecting plate 21 rotates around the first vertical rod 11. When the handle 232 contacts the second vertical rod 3, press the front surface of the connecting plate 21; at this time, the second vertical rod 3 abuts against the handle 232 and generates an interaction force with the handle 232, forcing the handle 232 to drive the elastic piece 231 to deform, forming an avoidance for the second vertical rod 3. The second vertical rod 3 is inserted into the locking groove. At this time, the interaction between the second vertical rod 3 and the handle 232 disappears, and the elastic piece 231 resets, and the second vertical rod 3 cannot be disengaged from the locking groove, thus forming a lock.
[0043] When the limit needs to be released and the cage door 1 is opened, pull the handle 232 forward, forcing the handle 232 to drive the elastic piece 231 to deform, forming an avoidance for the second vertical rod 3, and the second vertical rod 3 is disengaged from the locking groove.
[0044] A snap-type cage door of the present utility model solves the technical problems in the prior art that when the cage door of a full-metal snap is opened and closed, the limit structure makes it difficult to open and close the cage door, and once the limit fails, the maintenance difficulty and cost are relatively high. The present utility model sets a detachable snap on the cage door, thus replacing the deformation limit of the cage door cross bar with the limit of the snap. It does not require much effort to open and close the snap, thereby reducing the difficulty of opening and closing the cage door; at the same time, the snap is easy to replace, reducing the maintenance cost and difficulty.
[0045] Certainly, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present utility model should also belong to the protection scope of the present utility model.
