Description

Technical Field

[0001] This utility model belongs to the field of pull-out dog cabin technology, specifically a pull-out dog cabin that is easy to self-lock. Background Technology

[0002] Pull-out dog cabins are typically designed for law enforcement and rescue operations. They are easy to pull out and use, and are commonly used to transport police dogs, search and rescue dogs, etc., providing a safe and comfortable environment for dogs.

[0003] For example, utility model publication CN205962253U relates to a laboratory dog ​​cage, belonging to the field of laboratory animal science within the field of biotechnology. The dog cage includes a cage body and a tray located below the cage body. The cage body includes multiple uprights, opposing upper and lower horizontal rails, and a cage door. The upper and lower horizontal rails are connected to the uprights and integrally formed. The tray is fixed to the uprights. One side of the cage door is hinged to an adjacent upright via a pivot. A pin extending from the other side of the cage door is fixed to the other upright. A lock is provided on the upright on the other side of the adjacent cage door. The lock includes a small column fixed to and extending from the column surface, a base plate abutting the column surface, and a handle and a hook fixed to the base plate. The small column has an enlarged head, and the base plate has an elongated hole extending along its height. The width of the enlarged head is greater than the width of the elongated hole. The small column passes through the elongated hole and places the base plate between the column surface and the enlarged head. This dog cage can securely and reliably lock the cage door to prevent animal escape.

[0004] The aforementioned device enhances its locking mechanism through the cooperation of structures such as the latch and the locking hook. However, the device requires manual opening and closing of the door by the operator. While a dog is being placed inside, the open door may close due to external factors, interfering with the dog's entry into the cage. Furthermore, if multiple dogs need to frequently enter and exit, manually closing the door consumes a significant amount of time and effort, thus reducing the overall practicality and convenience of the device. Therefore, a self-locking pull-out dog cage is proposed to address the problems mentioned in the background art. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a pull-out dog cabin that is easy to lock, which has the advantages of convenient automatic closing and self-locking, thereby improving the overall convenience and practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-locking pull-out dog cabin, comprising a dog cabin body, a door panel hinged to one side of the dog cabin body, a connecting rod hinged to the top of the door panel, a sliding plate movably connected inside the top of the dog cabin body, a first spring plate fixedly connected to the side of the sliding plate away from the connecting rod, a support plate movably connected inside the dog cabin body, limit blocks fixedly connected to both sides of the support plate, a slanted groove formed on the top surface of the limit blocks, two first slanted blocks symmetrically movably connected inside the top of the dog cabin body, springs fixedly connected to the four corners of the bottom of the support plate, a second slanted block movably connected inside the side of the dog cabin body near the door panel, a second spring plate fixedly connected to the top of the second slanted block, and the second spring plate fixedly attached to the dog cabin body.

[0007] Preferably, the surface of the sliding plate is provided with a groove, and the end of the connecting rod away from the door panel is movably engaged inside the groove. The sliding plate is elastically connected to the dog cabin body through a first spring sheet.

[0008] Preferably, the end of the first inclined block near the slide plate is inclined, and the slide plate abuts against the inclined surface of the first inclined block after moving towards the outside of the dog cabin body.

[0009] Preferably, both sides of the first inclined block are provided with connecting posts that are movably engaged inside the inclined groove, and the inner wall of the dog cabin body is provided with a square groove for limiting the first inclined block in the horizontal direction.

[0010] Preferably, the two inclined grooves are oriented in opposite directions, and when the limiting block moves down, it causes the two first inclined blocks to move in opposite directions along the trajectories of the two inclined grooves respectively.

[0011] Preferably, the bottom end of the second inclined block is inclined, and the second inclined block is initially inserted into the door panel. The second spring sheet is used to squeeze the second inclined block and keep the second inclined block moving downward.

[0012] Preferably, a pull rod is fixedly connected to one side of the second spring piece. The pull rod passes through the outer wall of the dog cabin body and extends to the outside of the dog cabin body. Slide rails are provided at the upper and lower ends of both sides of the dog cabin body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention features a structure including a sliding plate, a support plate, a first inclined block, and a second inclined block. This allows the device to automatically close and self-lock after a dog enters the dog compartment. The first inclined block engages with the inside of a sloping groove. Once the dog enters the compartment, the support plate, under the dog's weight, moves the limiting block downwards, causing the two first inclined blocks to move in opposite directions, releasing the limiting effect on the sliding plate. The design of the first spring allows the sliding plate to reset under the tension of the spring after being released, then, via a connecting rod, rotate the door panel 90 degrees in the opposite direction, thus blocking the dog compartment and achieving automatic closing. The design of the second inclined block allows it to engage with the inside of the door panel under the elastic force of the second spring after the door panel has closed, achieving self-locking of the door panel. This improves the overall convenience and practicality of the device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5As shown, this utility model provides a self-locking pull-out dog cabin, including a dog cabin body 1, a door panel 2 hinged to one side of the dog cabin body 1, a connecting rod 3 hinged to the top of the door panel 2, a sliding plate 4 movably connected inside the top of the dog cabin body 1, a first spring piece 6 fixedly connected to the side of the sliding plate 4 away from the connecting rod 3, a support plate 7 movably connected inside the dog cabin body 1, limit blocks 8 fixedly connected to both sides of the support plate 7, a groove 9 opened on the surface of the top of the limit block 8, two first inclined blocks 10 symmetrically movably connected inside the top of the dog cabin body 1, spring rods 11 fixedly connected to the four corners of the bottom of the support plate 7, the bottom end of the spring rods 11 fixedly connected to the dog cabin body 1, a second inclined block 12 movably connected inside the side of the dog cabin body 1 near the door panel 2, a second spring piece 13 fixedly connected to the top of the second inclined block 12, and the second spring piece 13 fixedly connected to the dog cabin body 1.

[0023] The above scheme is adopted as follows: the first inclined block 10 is movably engaged inside the inclined groove 9, so that after the dog enters the dog cabin body 1, the support plate 7 will move the limiting block 8 downward under the action of the dog's gravity, thereby causing the two first inclined blocks 10 to move in opposite directions, releasing the limitation on the slide plate 4. Through the design of the first spring plate 6, the slide plate 4 can be reset under the action of the pulling force of the first spring plate 6 after the limitation is released, and then the connecting rod 3 will drive the door panel 2 to rotate 90 degrees in the opposite direction, thereby blocking the dog cabin body 1 and achieving the effect of automatic closing. Through the design of the second inclined block 12, after the door panel 2 closes the dog cabin body 1, the second inclined block 12 can be engaged inside the door panel 2 under the action of the elastic force of the second spring plate 13, thereby achieving the self-locking of the door panel 2, thereby improving the overall convenience and practicality of the device.

[0024] like Figure 2 , Figures 4 to 5 As shown, the surface of the slide plate 4 is provided with a groove 5. The end of the connecting rod 3 away from the door panel 2 is movably engaged inside the groove 5. The slide plate 4 is elastically connected to the dog cabin body 1 through the first spring piece 6. The end of the first inclined block 10 near the slide plate 4 is inclined. After the slide plate 4 moves towards the outside of the dog cabin body 1, it abuts against the inclined surface of the first inclined block 10. Both sides of the first inclined block 10 are provided with connecting posts that are movably engaged inside the inclined groove 9. The inner wall of the dog cabin body 1 is provided with a square groove for limiting the first inclined block 10 in the horizontal direction.

[0025] The above solution is adopted: a square groove is provided on the inner wall of the dog cabin body 1. Its function is that when the limiting block 8 moves down, the square groove limits the first inclined block 10 in the horizontal direction. Therefore, the first inclined block 10 can only move along the trajectory of the inclined groove 9 in a direction away from the slide plate 4, thereby ensuring the normal operation of the device.

[0026] like Figure 1 , Figures 3 to 4As shown, the two inclined grooves 9 face opposite directions. When the limiting block 8 moves down, it drives the two first inclined blocks 10 to move in opposite directions along the tracks of the two inclined grooves 9 respectively. The bottom end of the second inclined block 12 is inclined. In the initial state, the second inclined block 12 is stuck inside the door plate 2. The second spring piece 13 is used to squeeze the second inclined block 12 and keep the second inclined block 12 moving downward. A pull rod 14 is fixedly connected to one side of the second spring piece 13. The pull rod 14 passes through the outer wall of the dog cabin body 1 and extends to the outside of the dog cabin body 1. Slide rails 15 are provided at both the upper and lower ends of both sides of the dog cabin body 1.

[0027] The above solution is adopted: the function of the slide rail 15 is to help to quickly and accurately install the dog cabin body 1 into the outer frame when installing the dog cabin body 1. The position of the slide rail on the outer frame is fixed and has been precisely set during the manufacturing process. The design of the slide rail 15 makes the installation process of the dog cabin body 1 simpler and more efficient. At the same time, the slide rail can also facilitate the pulling operation of the dog cabin body 1 within the outer frame.

[0028] The working principle and usage process of this utility model are as follows: The operator pulls the lever 14 to move the second inclined block 12 upward, thereby disengaging the second inclined block 12 from the door panel 2. Then, by pulling the door panel 2, the door panel 2 is rotated, and the connecting rod 3 pulls the slide plate 4 towards the outside of the dog cabin body 1. While the slide plate 4 is moving, one end of the connecting rod 3 slides inside the slide groove 5. Then, the outer wall of the slide plate 4 abuts against the inclined surfaces of the two first inclined blocks 10, and the two first inclined blocks 10 are pressed to move in opposite directions. While the first inclined blocks 10 are moving, the limiting block 8 and the support plate 7 are moved downward through the inclined groove 9. When the door panel 2 is rotated 90 degrees, the slide plate 4 will release its contact with the first inclined blocks 10, thereby causing the support plate 7 to move the limiting block 8 upward under the elastic force of the spring rod 11, thereby resetting the two first inclined blocks 10. This causes the plane of the first inclined block 10 to abut against the outer wall of the slide plate 4, thereby limiting the position of the slide plate 4 and preventing the door panel 2 from closing.

[0029] When a person places a dog into the dog compartment 1, the support plate 7 will move the limiting block 8 downward due to the weight of the dog. As the limiting block 8 moves downward, it will cause the first inclined block 10 to move away from the slide plate 4 along the trajectory of the inclined groove 9. This will release the first inclined block 10 from limiting the slide plate 4. Subsequently, the slide plate 4 will reset under the pulling force of the first spring 6, and then drive the door panel 2 to rotate 90 degrees in the opposite direction to close it through the connecting rod 3. After the door panel 2 rotates, it will abut against the inclined surface of the second inclined block 12 on the inner wall of the dog compartment 1, thereby squeezing the second inclined block 12 upward. When the door panel 2 completely blocks one side of the dog compartment 1, the second inclined block 12 will be locked inside the door panel 2 under the elastic force of the second spring 13, thus facilitating the self-locking of the device.
