[0009] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0010] This utility model provides a deceleration device for a cleaning machine door, including a housing and a door.

[0029] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0030] Figure 1 This is a three-dimensional schematic diagram of the deceleration device for the door of a cleaning machine provided in one embodiment of this utility model. Figure 1As shown, this embodiment provides a deceleration device for a cleaning machine door, including a housing 1 and a door 2. The door 2 is hinged to the housing 1, and the bottom of the door 2 is hinged to the bottom of the housing 1. The top of the door 2 is provided with a locking device for locking the door 2. The locking device is a conventional structure and is not described in detail in this embodiment. The deceleration device mainly includes a push plate 3 set on the side wall of the door 2. The push plate 3 is close to the hinge shaft between the door 2 and the housing 1. Alternatively, a through hole can be provided in the middle of the push plate 3. The push plate 3 is directly sleeved on the hinge shaft. One side of the push plate 3 is connected to the side wall of the door 2 by bolts.

[0031] The push plate 3 can rotate synchronously with the door 2 when the door 2 is opened. The side wall of the chassis 1 is provided with an elastic telescopic structure, and the push plate 3 abuts against the elastic telescopic structure after rotation.

[0032] In this embodiment, the deceleration device of the cleaning machine door mainly consists of a push plate 3 and an elastic telescopic structure, which is relatively simple in structure. The push plate 3 rotates synchronously with the rotation of the door 2. After the push plate 3 rotates, it abuts against the elastic telescopic structure. At this time, the push plate 3 continues to rotate, and the elastic telescopic structure will compress to generate elastic force. The elastic force will put resistance to the rotation of the push plate 3, reducing the angular velocity of the push plate 3. When the angular velocity of the push plate 3 is lower, the angular velocity of the door 2 will also decrease, which improves the safety of the door 2 opening process and can effectively control the opening speed of the door 2. Secondly, wear is less likely to occur between the push plate 3 and the elastic telescopic structure, which improves the service life of the deceleration device of the cleaning machine door.

[0033] As a further optimization of this embodiment, such as Figure 1 and Figure 2 As shown, there are two push plates 3, which are respectively installed on the two side walls of the door 2, and two sets of elastic telescopic structures are deployed, which are respectively installed on the two side walls of the chassis 1.

[0034] In this embodiment, the simultaneous deployment of push plates 3 and elastic telescopic structures on both sides can further improve the stability of the door 2 opening process.

[0035] As a further optimization of this embodiment, the push plate 3 has an L-shaped structure, and when the door 2 is closed, there is a gap between the end of the push plate 3 and the elastic telescopic structure. When the door 2 is first opened, since the end of the push plate 3 is not in contact with the elastic telescopic structure, the elastic telescopic structure will not resist the rotation of the push plate 3, and the door 2 can be opened easily, avoiding resistance when opening the door 2. When the door 2 rotates a certain angle, for example, 40°, the end of the push plate 3 comes into contact with the elastic telescopic structure, and the elastic telescopic structure resists the rotation of the push plate 3, thereby reducing the rotational angular velocity of the door 2. Therefore, when the opening angle of the door 2 reaches 40°, the opening of the door 2 begins to decelerate.

[0036] As a further optimization of this embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, the elastic telescopic structure includes: a linear module 4 and a tensioner 5. The linear module 4 is located between the push plate 3 and the tensioner 5. The linear module 4 is installed on the outer wall of the chassis 1. The mounting end of the tensioner 5 is connected to the outer wall of the chassis 1, and the telescopic end of the tensioner 5 is connected to the linear module 4.

[0037] The linear module 4 includes a slide rail 401 fixedly mounted on the outer wall of the housing 1, with a slide plate 402 slidably connected to the slide rail 401. The tensioner 5 is a gas spring, which includes an outer tube 501 and a central rod 502. The central rod 502 is inserted into the outer tube 501, with the end of the outer tube 501 away from the central rod 502 serving as the mounting end of the tensioner 5, and the end of the central rod 502 away from the outer tube 501 serving as the telescopic end of the tensioner 5. The outer tube 501 is filled with an inert gas medium, and a spring is provided inside the outer tube 501. Nitrogen is preferably used as the inert gas medium. The spring is not shown in the attached drawings.

[0038] In this embodiment, with Figure 1 For example, when the push plate 3 rotates counterclockwise and contacts the slide plate 402, the push plate 3 continues to rotate counterclockwise. At this time, the push plate 3 will push the slide plate 402 to slide upward on the slide rail 401. After the slide plate 402 slides upward, the center rod 502 of the tensioner 5 retracts into the outer tube 501, and the spring is compressed, generating elastic force. The generated elastic force can resist the rotation of the push plate 3 and reduce the rotational angular velocity of the push plate 3. Secondly, the sliding friction between the slide rail 401 and the slide plate 402 can also resist the rotation of the push plate 3. At this time, the combination of sliding friction and elastic force can effectively reduce the rotational angular velocity of the push plate 3 and improve the safety of the opening process of the box door 2.

[0039] As a further optimization of this embodiment, the slide plate 402 is provided with a plurality of mounting holes 403 at the end away from the push plate 3. The plurality of mounting holes 403 are distributed horizontally. The telescopic end of the tensioner 5 is connected to any one of the mounting holes 403. The connection between the tensioner 5 and the mounting hole 403 is a hinge. The connection between the tensioner 5 and the outer wall of the housing 1 is also a hinge.

[0040] In this embodiment, after the telescopic end of the tensioner 5 is installed in the mounting holes 403 at different positions, the tensioner 5 can be in a vertical or inclined state. When the tensioner 5 is in a vertical state, the moving direction of the central rod 502 of the tensioner 5 is consistent with the sliding direction of the slide plate 402, so the compression of the spring of the tensioner 5 is equal to the displacement of the slide plate 402. When the tensioner 5 is in an inclined state, the moving direction of the central rod 502 of the collector is inconsistent with the sliding direction of the slide plate 402, so the compression of the spring of the tensioner 5 is greater than the displacement of the slide plate 402. At this time, the tensioner 5 can provide greater elasticity, thereby generating greater resistance to the rotation of the push plate 3 and further improving safety.

[0041] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
