Abstract

This invention belongs to the field of biological experimental technology, specifically relating to a cage door structure for a feeding box with a self-locking mechanism. It includes a feeding box base, a cage frame fixedly connected to the outer wall of the base, and a cage door rotatably connected to the cage frame. The cage frame is engaged with the cage door via a self-locking component. This cage door structure, through its self-locking and limiting components, allows for adjustment of the hinge angle between the connecting plate and the hinge plate when the cage door is pulled. Inserting the connecting plate into the limiting frame causes the engaging block to retract into a movable groove under pressure from the limiting frame. A return spring, compressed and storing elastic potential energy, releases the engaging block after it passes the limiting frame, causing the end of the engaging block to tilt upwards and engage with the limiting frame. Rotating the block moves the limiting rod upwards, releasing the elastic plate and causing it to open outwards, thereby increasing the friction between the self-locking component and the cage frame, improving the stability of the self-locking effect, and protecting human health and animal safety.

Description

Technical Field

[0001] This invention relates to the field of biological experimental technology, specifically to a cage door structure for a feeding box with a self-locking mechanism. Background Technology

[0002] A cage door is a door structure installed at the opening of an animal enclosure. Animal enclosures are common equipment in pet stores, pet-owning households, and laboratories, used to provide animals with a safe and suitable living environment.

[0003] Currently, the design of cage doors in existing technologies is relatively simple, without an integrated self-locking mechanism. They rely solely on simple latches or buckles to keep the cage closed, which are prone to failure when subjected to external forces, leading to accidental opening of the cage door. Furthermore, cage doors may also open accidentally when bumped by animals or disturbed by external forces, increasing the risk of animal escape. In view of this, we propose a cage door structure with a self-locking mechanism. Summary of the Invention

[0004] The main objective of this invention is to provide a cage door structure for a feeding box with a self-locking mechanism, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a cage door structure with a self-locking mechanism, comprising a cage base, a cage frame fixedly connected to the outer wall of the cage base, a cage door rotatably connected to the cage frame, the cage frame being engaged with the cage door via a self-locking component, a limit component being provided on the self-locking component, a one-way movable component being provided on the cage door, and a linkage component being provided on the one-way movable component. The self-locking component includes:

[0006] A rotating shaft is rotatably connected to the cage door, and a hinge plate is fixedly connected to the rotating shaft;

[0007] A connecting plate is hinged to the hinge plate, and a movable groove is provided on the connecting plate. The movable groove is elastically connected to the rear end of the snap-fit ​​block through a return spring, and the front end of the snap-fit ​​block is rotatably connected in the movable groove.

[0008] A limiting frame is fixedly connected to the cage frame, and the limiting frame is engaged with a locking block.

[0009] Preferably, the limiting component includes a limiting rod, and the limiting frame is provided with the limiting rod. The outer wall of the limiting rod has a threaded section, and the limiting rod is threadedly connected to the limiting frame through the threaded section. The limiting rod is threadedly connected to the limiting frame through the threaded section on its outer wall, so that the limiting rod can move up and down within the limiting frame, and its position can be adjusted by rotating the limiting rod.

[0010] Preferably, an elastic sheet is fixedly connected to the outer wall of the limiting rod, and multiple sets of elastic sheets are provided. A rotating block is threadedly connected to the limiting rod. When the elastic sheet is not compressed, it naturally opens outward to increase the contact area. By rotating the rotating block, the limiting rod can be driven to move up and down within the limiting frame. When it is necessary to release the compression of the elastic sheet, the limiting rod is moved upward by rotating the rotating block, and the elastic sheet is released and opens outward, thereby increasing the friction between the self-locking component and the cage.

[0011] Preferably, the one-way movable component includes a rotating transparent plate, which is rotatably connected to the cage door, and a blocking plate is fixedly connected to the cage door below the rotating transparent plate. The rotating transparent plate allows observation of the cage interior or transfer of items without opening the cage door.

[0012] Preferably, the baffle plate has an inclined surface on the side near the inside of the cage, and a rotating transparent plate is placed on the inclined surface. The resistance generated by the inclination angle of the inclined surface prevents the rotating transparent plate from rotating outward.

[0013] Preferably, the linkage component includes a pressing block, which is provided on the cage door and is located behind the hinge plate. After the self-locking component and the limiting component are installed, the stable limiting allows the hinge plate to stably press the pressing block into the inner cavity of the cage door.

[0014] Preferably, the extrusion block penetrates through the cage door, and a limiting plate is fixedly connected to the extrusion block. The limiting plate is elastically connected to the inner cavity of the cage door by a spring. During the extrusion process, the extrusion block drives the limiting plate to extend continuously through the spring.

[0015] Preferably, a movable rod is provided behind the limiting plate, and a sliding plate is fixedly connected to the movable rod. A fixed plate is fixedly connected to the inner cavity of the cage door. The sliding plate and the fixed plate are elastically connected by a spring. The movement of the limiting plate pushes the inclined surface of the movable rod, causing the movable rod to move downward. The movement of the movable rod causes the sliding plate to continuously compress the spring and move closer to the fixed plate.

[0016] Preferably, a fixing block is fixedly connected to the inner cavity of the cage door, and a lifting groove is formed on the inner wall of the fixing block, and the lifting groove passes through the cage door.

[0017] Preferably, an auxiliary plate is provided in the lifting groove, and a connecting rod is fixedly connected to the auxiliary plate. The connecting rod is slidably connected in an inclined groove opened in the inner wall of the fixed block. The movable rod is an elastic structure. When the movable rod moves down, the lower end of the movable rod is pushed forward by the outer shape limit of the cage door until it pushes the auxiliary plate.

[0018] This invention provides a cage door structure for a feeding box with a self-locking mechanism. It has the following beneficial effects:

[0019] (1) The cage door structure of the feeding box with self-locking structure, through the self-locking component and the limiting component, pulls the cage door, adjusts the hinge angle between the connecting plate and the hinge plate, inserts the connecting plate into the limiting frame on the cage frame, and the locking block is squeezed by the limiting frame and retracts into the movable groove as a whole. The return spring is squeezed and stores elastic potential energy. When the locking block passes the limiting frame, the return spring pops out and drives the locking block to tilt up and lock with the limiting frame. Rotating the rotating block causes the limiting rod to move up, the elastic plate is released and opens outward, thereby increasing the friction between the self-locking component and the cage frame, improving the stability of the self-locking effect, and protecting the health of personnel and the safety of animals.

[0020] (2) The cage door structure with self-locking structure has a one-way moving component. When it is necessary to put food into the cage from outside or to observe the situation inside the cage, the staff can gently push the rotating transparent plate inward. When the animal tries to push the rotating transparent plate outward from inside the cage, the slope prevents the transparent plate from rotating outward through the resistance generated by its tilt angle. The animal's action of pushing the rotating transparent plate cannot be successful, thus ensuring the safety of the cage door.

[0021] (3) The cage door structure of the feeding box with self-locking structure is equipped with a linkage component. After the self-locking component and the limiting component are installed, the hinge plate stably squeezes the squeezing block into the inner cavity of the cage door. The squeezing block drives the limiting plate to extend continuously through the spring. The limiting plate pushes the inclined surface of the moving rod, so that the moving rod moves downward until it pushes the auxiliary plate. The auxiliary plate is inclined upward along the inclined groove opened by the fixed block through the connecting rod, which plays a blocking role and prevents the animals from hitting the feeding box due to stress response, reducing the risk of animal escape and improving the ease of operation.

[0043] It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0044] Please see Figure 1-12 This invention proposes a cage door structure for a breeding box with a self-locking mechanism, including a breeding box base 1, a cage frame 2 fixedly connected to the outer wall of the breeding box base 1, a cage door 3 rotatably connected to the cage frame 2, the cage frame 2 being engaged with the cage door 3 by a self-locking component 4, a limit component 5 being provided on the self-locking component 4, a one-way movement component 6 being provided on the cage door 3, a linkage component 7 being provided on the one-way movement component 6, and the self-locking component 4 including a rotating shaft 41.

[0045] In an embodiment of the present invention, in order to improve the stability of the self-locking effect and protect the health of personnel and the safety of animals, a rotating shaft 41 is rotatably connected to the cage door 3, and a hinge plate 42 is fixedly connected to the rotating shaft 41. A connecting plate 43 is hinged to the hinge plate 42, and a movable groove 44 is provided on the connecting plate 43. The movable groove 44 is elastically connected to the rear end of the locking block 46 through a return spring 45, and the front end of the locking block 46 is rotatably connected in the movable groove 44. A limit frame 47 is fixedly connected to the cage frame 2 for limiting movement. The frame 47 engages with the locking block 46. The operator pulls the cage door 3, turning it towards the cage frame 2. Adjusting the hinge angle between the connecting plate 43 and the hinge plate 42, the operator inserts the connecting plate 43 into the limiting frame 47 on the cage frame 2. The front end of the locking block 46 on the connecting plate 43 first contacts the limiting frame 47. After being compressed by the limiting frame 47, it retracts entirely into the movable groove 44. The return spring 45 is compressed and stores elastic potential energy. When the rear end of the locking block 46 has completely passed through the limiting frame 47, the return spring 45 pops out. The rear end of the movable locking block 46 tilts up to engage with the limiting frame 47. The limiting assembly 5 includes a limiting rod 51, which is mounted on the limiting frame 47. The outer wall of the limiting rod 51 has a threaded section 52, which connects the limiting rod 51 to the limiting frame 47. The threaded connection between the limiting rod 51 and the limiting frame 47 is achieved through the threaded section 52 on its outer wall, allowing the limiting rod 51 to move up and down within the limiting frame 47. The position can be adjusted by rotating the limiting rod 51. An elastic sheet 53 is fixedly connected, and multiple sets of elastic sheets 53 are provided. A rotating block 54 is threadedly connected to the limiting rod 51. When the elastic sheet 53 is not compressed, it naturally opens outward to increase the contact area. By rotating the rotating block 54, the limiting rod 51 can be driven to move up and down within the limiting frame 47. When it is necessary to release the pressure on the elastic sheet 53, the limiting rod 51 is moved upward by rotating the rotating block 54, and the elastic sheet 53 is released and opens outward, thereby increasing the friction between the self-locking component 4 and the cage 2.

[0046] In an embodiment of the present invention, in order to facilitate food delivery and prevent animals from accidentally leaving the cage 2, the one-way moving component 6 includes a rotating transparent plate 61. The rotating transparent plate 61 is rotatably connected to the cage door 3, and a blocking plate 62 is fixedly connected to the cage door 3 below the rotating transparent plate 61. The rotating transparent plate 61 allows observation of the cage interior or delivery of food without opening the cage door 3. The blocking plate 62 has an inclined surface 63 on the side closest to the inside of the cage 2, and the rotating transparent plate 61 is placed on the inclined surface 63. The resistance generated by the inclination angle of the inclined surface 63 prevents the rotating transparent plate 61 from rotating outward. When it is necessary to deliver food from outside the cage to inside or observe the cage interior, the staff can gently push the rotating transparent plate 61 inward. When the animal attempts to push the rotating transparent plate 61 outward from inside the cage, the resistance generated by the inclination angle of the inclined surface 63 prevents the transparent plate from rotating outward, and the animal's action of pushing the rotating transparent plate 61 cannot succeed, ensuring the safety of the cage door 3.

[0047] In an embodiment of the present invention, in order to reduce the risk of animal escape and improve operational portability, the linkage component 7 includes a squeezing block 71. The squeezing block 71 is provided on the cage door 3 and is located behind the hinge plate 42. After the self-locking component 4 and the limiting component 5 are installed, the stable limiting allows the hinge plate 42 to stably squeeze the squeezing block 71 into the inner cavity of the cage door 3. The limiting plate 73 is elastically connected to the inner cavity of the cage door 3 by a spring 72. During the squeezing process, the squeezing block 71 drives the limiting plate 73 to extend continuously through the spring 72. A movable rod 74 is provided behind the limiting plate 73. The movable rod 74 is fixedly connected to a sliding plate 75, and a fixed plate 77 is fixedly connected to the inner cavity of the cage door 3. The sliding plate 75 and the fixed plate 77 are connected by a spring. The spring 76 is elastically connected, and the movement of the limiting plate 73 pushes the inclined surface of the movable rod 74, causing the movable rod 74 to move downward. The movement of the movable rod 74 causes the sliding plate 75 to continuously compress the spring 76 and move closer to the fixed plate 77. A fixed block 78 is fixedly connected in the inner cavity of the cage door 3. A lifting groove 79 is opened on the inner wall of the fixed block 78 and passes through the cage door 3. An auxiliary plate 712 is set in the lifting groove 79. A connecting rod 711 is fixedly connected to the auxiliary plate 712 and is slidably connected in the inclined groove 710 opened in the inner wall of the fixed block 78. The movable rod 74 is an elastic structure. When the movable rod 74 moves downward, the lower end of the movable rod 74 is pushed forward by the outer shape limitation of the cage door 3 until it pushes the auxiliary plate 712.

[0048] In this invention, during use, the operator first pulls the cage door 3, turns the cage door 3 towards the cage frame 2, adjusts the hinge angle between the connecting plate 43 and the hinge plate 42, inserts the connecting plate 43 into the limiting frame 47 on the cage frame 2, and the front end of the snap-fit ​​block 46 on the connecting plate 43 first contacts the limiting frame 47. After being squeezed by the limiting frame 47, the whole block retracts into the movable groove 44. The return spring 45 is compressed and stores elastic potential energy. When the rear end of the snap-fit ​​block 46 has completely passed through the limiting frame 47, the return spring 45 pops out and drives the rear end of the snap-fit ​​block 46 to tilt up and snap into the limiting frame 47. By rotating the rotating block 54, the limiting rod 51 moves upward, and the elastic sheet 53 is released and opens outward, thereby increasing the friction between the self-locking component 4 and the cage frame 2, improving the stability of the self-locking effect, and protecting the health of personnel and the safety of animals.

[0049] When it is necessary to feed food from outside the cage to inside the cage or to observe the situation inside the cage, the staff can gently push the rotating transparent plate 61 inward. When the animal tries to push the rotating transparent plate 61 outward from inside the cage, the slope 63 prevents the transparent plate from rotating outward through the resistance generated by its tilt angle. The animal's action of pushing the rotating transparent plate 61 cannot be successful, thus ensuring the safety of the cage door 3.

[0050] After the self-locking component 4 and the limiting component 5 are installed, the hinge plate 42 stably presses the pressing block 71 into the inner cavity of the cage door 3. The pressing block 71 drives the limiting plate 73 to extend continuously through the spring 72. The movement of the limiting plate 73 pushes the inclined surface of the moving rod 74, causing the moving rod 74 to move downward. The movement of the moving rod 74 causes the sliding plate 75 to continuously compress the spring 76 and move closer to the fixed plate 77. Since the moving rod 74 is an elastic structure, after the moving rod 74 moves downward, the lower end of the moving rod 74 is pushed forward by the outer shape of the cage door 3 until it pushes the auxiliary plate 712. The auxiliary plate 712 is inclined upward along the inclined groove 710 opened by the connecting rod 711 along the fixed block 78, which plays a blocking role. The self-locking component 4 further enhances the safety of the one-way moving component 6, prevents animals from hitting the feeding box due to stress response, reduces the risk of animal escape, and improves the ease of operation.

[0051] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
