Description

Technical Field

[0001] The invention relates to the technical field of biological experiments, in particular to a breeding box cage door structure with a self-locking structure. Background Art

[0002] The cage door is a door structure set at the opening of the cage used to raise animals. In pet shops, animal breeding homes, laboratories and other places, vivariums are common equipment used to provide a safe and suitable living environment for animals.

[0003] At present, in the existing technology, the design of the cage door of the breeding box is relatively simple, without an integrated self-locking mechanism, and only relies on a simple latch or buckle to maintain the closed state. It is easy to fail when subjected to external force, causing the cage door to open accidentally. Moreover, the cage door of the breeding box may accidentally open when it is hit by the animal or external interference, increasing the risk of animal escape. In view of this, we propose a cage door structure of the breeding box with a self-locking structure. Summary of the Invention

[0004] The main purpose of the present invention is to provide a cage door structure with a self-locking structure, which can solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention proposes a cage door structure with a self-locking structure for a feeding box, comprising a feeding box base, an outer wall of the feeding box base being fixedly connected to a cage frame, a cage door being rotatably connected to the cage frame, the cage frame being clamped to the cage door via a self-locking component, a limiting component being provided on the self-locking component, a one-way movable component being provided on the cage door, a linkage component being provided on the one-way movable component, and the self-locking component comprising:

[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, wherein the hinged plate is hingedly connected to the connecting plate, and a movable groove is formed on the connecting plate, the movable groove is elastically connected to the rear end of the clamping block through a return spring, and the front end of the clamping block is rotatably connected to the movable groove;

[0008] A limiting frame is fixedly connected to the cage frame, and the limiting frame is clamped with the clamping block.

[0009] Preferably, the limit assembly includes a limit rod, a limit rod is provided on the limit frame, a threaded section is provided on the outer wall of the limit rod, the limit rod is threadedly connected to the limit frame through the threaded section, and the limit rod is threadedly connected to the limit frame through the threaded section on its outer wall, so that the limit rod moves up and down in the limit frame, and the position is adjusted by rotating the limit rod.

[0010] Preferably, an elastic sheet is fixedly connected to the outer wall of the limit rod, and multiple groups of elastic sheets are provided. A rotating block is threadedly connected to the limit rod. The elastic sheet naturally opens outward when not compressed, increasing the contact area. By rotating the rotating block, the limit rod can be driven to move up and down in the limit frame. When it is necessary to release the squeezing of the elastic sheet, the limit 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 frame.

[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 the cage to be observed or items to be delivered without opening the cage door.

[0012] Preferably, a slope is provided on one side of the blocking plate close to the inside of the cage, and a rotatable transparent plate is placed on the slope. The resistance generated by the inclination angle of the slope prevents the rotatable transparent plate from rotating outward.

[0013] Preferably, the linkage assembly includes an extrusion block, and the cage door is provided with an extrusion block, and the extrusion block is arranged behind the hinge plate. When the self-locking assembly and the limiting assembly are installed, the stable limiting enables the hinge plate to stably extrude the extrusion block to move into the inner cavity of the cage door.

[0014] Preferably, the extrusion block passes through the cage door, a limiting disk is fixedly connected to the extrusion block, the limiting disk is elastically connected to the inner cavity of the cage door via a spring, and during the extrusion process, the extrusion block drives the limiting disk to continue to extend via the spring.

[0015] Preferably, a movable rod is provided behind the limiting plate, the movable rod is fixedly connected to a sliding plate, and 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 spring 2, the movement of the limiting plate pushes the inclined surface of the movable rod, causing the movable rod to move downward, and the movement of the movable rod causes the sliding plate to continuously compress spring 2 and approach the position of the fixed plate.

[0016] Preferably, a fixing block is fixedly connected to the inner cavity of the cage door, and a lifting groove is opened 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, the auxiliary plate is fixedly connected to a connecting rod, and the connecting rod is slidably connected to an inclined groove opened on the inner wall of the fixed block, and the movable rod is an elastic structure. When the movable rod moves downward, the lower end of the movable rod is pushed forward by the outer shape limit of the cage door until the auxiliary plate is pushed.

[0018] The present invention provides a cage door structure with a self-locking structure for a feeding box, which has the following beneficial effects:

[0019] (1) The cage door structure of the feeding box with a self-locking structure is provided with a self-locking component and a limit component. The cage door is pulled, the hinge angle of the connecting plate and the hinge plate is adjusted, and the connecting plate is inserted into the limit frame on the cage frame. The clamping block is squeezed by the limit frame and shrinks as a whole into the movable groove. The reset spring is squeezed to store elastic potential energy. When the clamping block passes through the limit frame, the reset spring pops out and drives the clamping block to tilt and engage with the limit frame. The rotating block is rotated to move the limit rod upward, and the elastic sheet 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 of the feeding box with a self-locking structure is provided with a one-way movable component. When it is necessary to deliver food from outside the cage to inside the cage or 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 from inside the cage to outside, the resistance generated by the inclined surface at its inclination angle prevents the transparent plate from rotating outward. The animal's action of pushing the rotating transparent plate open cannot be successful, thereby ensuring the safety of the cage door.

[0021] (3) The cage door structure of the feeding box with a self-locking structure is provided with a linkage component. When the self-locking component and the limit component are installed, the hinged plate stably squeezes the extrusion block to move into the inner cavity of the cage door. The extrusion block drives the limit plate to continue to extend through the spring. The limit plate pushes the inclined surface of the movable rod, causing the movable rod to move downward until it pushes the auxiliary plate. The auxiliary plate is tilted upward along the inclined groove opened by the fixed block through the connecting rod, which has a blocking effect, preventing the animal from hitting the feeding box due to stress reaction, reducing the risk of animal escape, and improving the portability of operation.

[0044] See also Figure 1-12 The present invention proposes a cage door structure of a breeding box with a self-locking structure, including a breeding box base 1, the outer wall of the breeding box base 1 is fixedly connected to a cage frame 2, the cage frame 2 is rotatably connected to a cage door 3, the cage frame 2 is clamped with the cage door 3 through a self-locking component 4, a limiting component 5 is provided on the self-locking component 4, a one-way movable component 6 is provided on the cage door 3, a linkage component 7 is provided on the one-way movable component 6, and the self-locking component 4 includes a rotating shaft 41.

[0045] In the 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, the cage door 3 is rotatably connected to a rotating shaft 41, and a hinge plate 42 is fixedly connected to the rotating shaft 41, and the hinge plate 42 is hinged to a connecting plate 43, and a movable groove 44 is opened on the connecting plate 43. The movable groove 44 is elastically connected to the rear end of the clamping block 46 through a reset spring 45, and the front end of the clamping block 46 is rotatably connected to the movable groove 44. A limit frame 47 is fixedly connected to the cage frame 2, and the limit frame 47 is fixedly connected to the cage frame 2. The frame 47 is engaged with the clamping block 46. The staff pulls the cage door 3 and turns the cage door 3 to the cage frame 2. The hinge angle of the connecting plate 43 and the hinge plate 42 is adjusted. The connecting plate 43 is inserted into the limiting frame 47 on the cage frame 2. The front end of the clamping block 46 on the connecting plate 43 first contacts the limiting frame 47. After being squeezed by the limiting frame 47, the whole body shrinks into the movable groove 44. The reset spring 45 is squeezed to store elastic potential energy. When the rear end of the clamping block 46 completely passes through the limiting frame 47, the reset spring 45 pops out with The rear end of the movable clamping block 46 is tilted to realize the clamping connection with the limit frame 47. The limit assembly 5 includes a limit rod 51. The limit rod 51 is provided on the limit frame 47. The outer wall of the limit rod 51 is provided with a threaded section 52. The limit rod 51 is threadedly connected to the limit frame 47 through the threaded section 52. The limit rod 51 is threadedly connected to the limit frame 47 through the threaded section 52 on its outer wall, so that the limit rod 51 moves up and down in the limit frame 47. The position is adjusted by rotating the limit rod 51. The outer wall of the limit rod 51 An elastic sheet 53 is fixedly connected, and multiple groups of elastic sheets 53 are provided. A rotating block 54 is threadedly connected to the limit rod 51. The elastic sheet 53 naturally opens outward when not compressed to increase the contact area. By rotating the rotating block 54, the limit rod 51 can be driven to move up and down in the limit frame 47. When it is necessary to release the squeezing of the elastic sheet 53, the limit 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 frame 2.

[0046] In an embodiment of the present invention, in order to facilitate the delivery of food and prevent the animal from accidentally leaving the cage 2, the one-way movable component 6 includes a rotating transparent plate 61, which 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 the cage to be observed or food to be delivered without opening the cage door 3. The blocking plate 62 is provided with an inclined surface 63 on one side close 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 the cage or 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 inclined surface 63 prevents the transparent plate from rotating outward due to the resistance generated by its inclination angle. The animal's action of pushing the rotating transparent plate 61 open fails, thereby 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 assembly 7 includes an extrusion block 71, an extrusion block 71 is provided on the cage door 3, and the extrusion block 71 is arranged behind the hinged plate 42. When the self-locking assembly 4 and the limiting assembly 5 are installed, the stable limiting allows the hinged plate 42 to stably squeeze the extrusion block 71 to move 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 extrusion process, the extrusion block 71 drives the limiting plate 73 to continue to extend 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 elastically connected. The second spring 76 is elastically connected, and the activity of the limit 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 second spring 76 and move closer to the fixed plate 77. A fixed block 78 is fixedly connected to the inner cavity of the cage door 3. A lifting groove 79 is provided on the inner wall of the fixed block 78, and the lifting groove 79 passes through the cage door 3. An auxiliary plate 712 is provided in the lifting groove 79. The auxiliary plate 712 is fixedly connected to the connecting rod 711, and the connecting rod 711 is slidably connected to the inclined groove 710 provided on 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 limit of the cage door 3 until the auxiliary plate 712 is pushed.

[0048] When the cage door 3 is in use, the staff first pulls the cage door 3 and turns the cage door 3 to the cage frame 2, adjusts the hinge angle of the connecting plate 43 and the hinge plate 42, and inserts the connecting plate 43 into the limit frame 47 on the cage frame 2. The front end of the clamping block 46 on the connecting plate 43 first contacts the limit frame 47, and after being squeezed by the limit frame 47, the whole body shrinks into the movable groove 44. The return spring 45 is squeezed and stores elastic potential energy. When the rear end of the clamping block 46 completely passes through the limit frame 47, the return spring 45 pops out and drives the rear end of the clamping block 46 to tilt up and realize the clamping connection with the limit frame 47. By rotating the rotating block 54, the limit 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 deliver food from outside the cage or observe the situation inside the cage, 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 inclined surface 63 at its inclined angle prevents the transparent plate from rotating outward. The animal's attempt to push the rotating transparent plate 61 away is unsuccessful, thereby ensuring the safety of the cage door 3.

[0050] When the locking cam 75 is in the closed position, the locking cam 73 is in the closed position, and the locking cam 73 is in the open position, so that the locking cam 73 is locked and the locking cam 73 is in the closed position.

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