Technical Field

[0001] This utility model relates to the field of automotive push-pull protective sleeve technology, and in particular to an automotive push-pull protective sleeve with a waterproof sealing device. Background Technology

[0002] Automotive push-pull protective sleeves are retractable protective devices primarily used to protect components such as hydraulic cylinder piston rods, cables, and air hoses from external damage such as dust, mud, and mechanical impacts. They are widely used in automotive tailgates, construction machinery, and special vehicles.

[0003] Existing automotive push-pull sleeves are directly fitted onto the outer surface of automotive pipelines to protect them. They are tightly connected to the pipeline connectors via elastic retainers. However, due to uneven fixation of the retainers, large gaps easily appear at the retainer joints, allowing rainwater to easily seep into the sleeve and damage the protected pipelines. Therefore, existing automotive push-pull sleeves are inconvenient to use. To address this, we provide an automotive push-pull sleeve with a waterproof sealing device. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing automotive push-pull sleeves that lack waterproofing at the port, and to provide an automotive push-pull sleeve with a waterproof sealing device.

[0009] In a preferred embodiment, one end of the sliding rod is provided with a semicircular block, and the semicircular block is fixedly connected to the sliding rod.

[0010] In a preferred embodiment, the two ends of the second spring are fixedly connected to the outer surface of the compression ring and the inner wall of the sleeve block, respectively.

[0011] In a preferred embodiment, the two ends of the spring are fixedly connected to the outer surfaces of the sliding ring and the sleeve block, respectively.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention, through the setting of a fixing mechanism and a pressing mechanism, allows the end of the automotive push-pull protective sleeve to be pressed and fixed during use, thereby enabling the sleeve body to be tightly connected to the metal connector of the protected pipeline in the vehicle. Furthermore, the sleeve body, after being compressed and deformed, effectively fills the gap between it and the metal connector, preventing rainwater from seeping into the sleeve body. A threaded ring is provided, which can rotate and move on the outer surface of the sleeve block, thus pressing the slightly protruding semi-circular block. This allows the semi-circular block to indirectly drive the arc-shaped piece to move. Additionally, a spring is provided, which generates elasticity when compressed. As the spring gradually returns to its original state, its elasticity acts on the sliding ring, pre-tightening the threaded ring and preventing automatic rotation. Attached Figure Description

[0023] 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. Example 1

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a vehicle push-pull protective sleeve with a waterproof sealing device, comprising: a sleeve body 1, with fixing mechanisms 2 at both ends of the sleeve body 1, the fixing mechanism 2 including a sleeve block 21, a threaded ring 22 sleeved on the outer surface of the sleeve block 21, the threaded ring 22 being threadedly connected to the sleeve block 21, a sliding ring 23 sleeved on the outer surface of the sleeve block 21, a spring 24 sleeved on the outer surface of the sleeve block 21, a pressing mechanism 3 provided inside the sleeve block 21, the pressing mechanism 3 including a sliding rod 31, an arc-shaped piece 32 provided at one end of the sliding rod 31, the arc-shaped piece 32 being fixedly connected to the sliding rod 31, the sleeve block 21 being sleeved on the outer surface of the sleeve body 1, the sleeve block 21 being fixedly connected to the sleeve body 1, the sliding ring 23 being slidably connected to the sleeve block 21, a limiting ring 25 sleeved inside the sliding ring 23, the limiting ring 25 being rotatably connected to the sliding ring 23, and the limiting ring 25 being fixedly connected to the threaded ring 22.

[0025] In this embodiment, by setting a threaded ring 22 and threading it to the sleeve block 21, the threaded ring 22 can remain stable after rotating and moving on the sleeve block 21. This allows the threaded ring 22 to continuously compress and fix the semi-circular block 35 inside the sleeve block 21. A sliding ring 23 is set and can slide on the outer surface of the sleeve block 21, so that the elastic force of the spring 24 can act on the threaded ring 22 through the sliding ring 23. In addition, a limiting ring 25 is set and can rotate inside the sliding ring 23, so that the limiting ring 25 can cooperate with the threaded ring 22 to keep the threaded ring 22 in a close fit with the sliding ring 23. This allows the elastic force of the spring 24 to act on the threaded ring 22 through the sliding ring 23, providing a preload force to prevent the threaded ring 22 from rotating. Example 2

[0026] like Figures 1-5 As shown, the sliding rod 31 is sleeved inside the sleeve block 21, and the sliding rod 31 is slidably connected to the sleeve block 21. A compression ring 33 is sleeved on the outer surface of the sliding rod 31, and the compression ring 33 is fixedly connected to the sliding rod 31. A second spring 34 is sleeved on the outer surface of the sliding rod 31. A semi-circular block 35 is provided at one end of the sliding rod 31, and the semi-circular block 35 is fixedly connected to the sliding rod 31. The two ends of the second spring 34 are respectively fixedly connected to the outer surface of the compression ring 33 and the inner wall of the sleeve block 21. The two ends of the first spring 24 are respectively fixedly connected to the sliding ring 23 and the outer surface of the sleeve block 21.

[0027] In this embodiment, by setting up the compression mechanism 3, the port of the sleeve body 1 is compressed, thereby ensuring a tight connection between the sleeve body 1 and the metal connector of the protected pipeline. At the same time, the deformation of the sleeve body 1 can fill the gap between it and the metal connector, thereby achieving the purpose of waterproofing and preventing internal seepage. Three arc-shaped pieces 32 are set up, and when the three arc-shaped pieces 32 are in a close-fitting state, they can form a complete closed loop, thus making the compression of the sleeve body 1 more uniform. A second spring 34 is set up, and the second spring 34 can generate elastic force when compressed. When the compression of the second spring 34 is removed, the elastic force of the second spring 34 will be released instantly, and the arc-shaped pieces 32 and other components will be automatically reset, allowing the sleeve body 1 to detach from the metal connector.

[0028] Working principle:

[0029] like Figures 1-5 As shown, in use, the sleeve body 1 can be first fitted onto the outer surface of the metal connector of the protected automotive pipeline. Then, the threaded ring 22 is rotated, and the threaded ring 22 can rotate and move on the outer surface of the sleeve block 21. At this time, the spring 24 is in a compressed state and gradually resets after the threaded ring 22 moves. The elastic force generated by the compression of the spring 24 can act on the threaded ring 22 through the sliding ring 23, so that the threaded ring 22 can be pre-tightened. Then the threaded ring 22 will continue to rotate and move. When the threaded ring 22 and the semicircular block 3... When contact occurs, the threaded ring 22 will press the semicircular block 35 into the interior of the sleeve block 21. At the same time, the semicircular block 35 will drive the sliding rod 31 to slide, so that the sliding rod 31 can drive the compression ring 33 to compress the second spring 34. Thus, the second spring 34 can generate elastic force, and the arc-shaped piece 32 can compress and deform the end of the sleeve body 1. Thus, the sleeve body 1 can be tightly and sealed with the metal joint, so that rainwater from the outside will not seep into the interior of the sleeve body 1, thereby protecting the automotive pipeline.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
