Description

Technical Field

[0001] This utility model belongs to the field of hollow sleeve technology and relates to a hollow sleeve for a car bumper tow hook. Background Technology

[0002] Automobiles are one of the most widely used modes of transportation, primarily powered by electricity, gasoline, or diesel. They are commonly used to transport people or goods. Car bumpers are crucial protective components, their main function being to absorb and cushion external impacts. Common materials for bumpers include plastic and metal. To facilitate the installation of tow hooks on the bumper area, a hollow sleeve is required. Existing sleeve technology, such as the one described in patent publication number CN202825676U, includes a body characterized by: all or part of the outer peripheral wall of the body being provided with anti-slip knurling. Compared to existing technologies, the advantages of this solution are: by providing all or part of the anti-slip knurling on the outer peripheral wall of the sleeve body, the sleeve provided by this invention has an anti-slip function, resulting in a better grip during use. Furthermore, the anti-slip knurling also makes the sleeve more aesthetically pleasing.

[0003] The aforementioned sleeve has the disadvantage of poor positioning effect for the tow hook. Therefore, we have designed a hollow sleeve for car bumper tow hooks. Summary of the Invention

[0004] The purpose of this utility model is to provide a hollow sleeve for a car bumper tow hook to solve the problems mentioned in the background art.

[0005] The purpose of this utility model can be achieved through the following technical solution: a hollow sleeve for a car bumper tow hook, comprising a sleeve body, a through hole provided in the inner wall of the sleeve body, a movable connecting rod installed inside the through hole, a universal ball joint provided at one end of the movable connecting rod, a horizontal pressure rod installed at one end of the universal ball joint, and a cleaning ring movably installed on the outer end face of the sleeve body.

[0006] In the aforementioned hollow sleeve for a car bumper tow hook, a connecting rod is provided on one side of the top end of the sleeve body, and a lifting ring is installed at one end of the connecting rod.

[0007] In the aforementioned hollow sleeve for a car bumper tow hook, a limiting crossbeam is installed inside the lifting ring, and a car head connecting bracket and an abutment are respectively installed at both ends of the limiting crossbeam.

[0008] In the aforementioned hollow sleeve for a car bumper tow hook, a scraper retainer is provided at the inner ring of the cleaning ring, and a plurality of annularly distributed cleaning scrapers are provided at the inner ring of the scraper retainer.

[0009] In the aforementioned hollow sleeve for a car bumper tow hook, the outer wall surface of the sleeve body is provided with anti-slip knurling.

[0010] In the aforementioned hollow sleeve for a car bumper tow hook, the movable link moves up and down inside the through hole but does not disengage from the through hole.

[0011] Compared with the prior art, the advantages of this hollow sleeve for a car bumper tow hook are as follows: By installing a movable connecting rod inside the through hole, with a universal ball joint at one end and a horizontal pressure bar at the other end of the universal ball joint, the tow hook inside the sleeve can be limited and positioned, making the position of the tow hook relatively stable inside the sleeve body and reducing the relative collision between the tow hook and the sleeve body; by setting a connecting rod at the top of the sleeve body, with a lifting ring at one end and a limiting crossbeam rod installed inside the lifting ring, it is easy to quickly install to the front bumper of the car, with good installation stability, and it is also convenient to adjust the position of the sleeve body relative to the cleaning ring, making it easier to clean the outer wall surface of the sleeve body.

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model relates to a hollow sleeve for a car bumper tow hook;

[0018] Example 1: The hollow sleeve includes a sleeve body 1. A through hole 9 is provided on the inner wall of the sleeve body 1. A movable connecting rod 8 is installed inside the through hole 9. A universal ball joint 10 is provided at one end of the movable connecting rod 8. A horizontal pressure rod 11 is installed at one end of the universal ball joint 10. A cleaning ring 2 is movably installed on the outer end face of the sleeve body 1. A scraper retainer 12 is provided on the inner ring of the cleaning ring 2. A plurality of annularly distributed cleaning scrapers 13 are provided on the inner ring of the scraper retainer 12.

[0019] The movable link 8 moves up and down inside the through hole 9, but the movable link 8 does not detach from the through hole 9.

[0020] When in use, the movable link 8 is pulled down to expose most of the space and place the tow hook inside the sleeve body 1. Then the movable link 8 is pushed up to rotate the horizontal pressure rod 11 to the horizontal position and use the horizontal pressure rod 11 to press down the tow hook. This can limit and position the tow hook inside the sleeve, making the position of the tow hook inside the sleeve body 1 relatively stable and reducing the relative collision between the tow hook and the sleeve body 1.

[0021] Example 2: The hollow sleeve includes a sleeve body 1. A through hole 9 is provided on the inner wall of the sleeve body 1. A movable connecting rod 8 is installed inside the through hole 9. A universal ball joint 10 is provided at one end of the movable connecting rod 8. A horizontal pressure rod 11 is installed at one end of the universal ball joint 10. A cleaning ring 2 is movably installed on the outer end face of the sleeve body 1. A scraper retainer 12 is provided on the inner ring of the cleaning ring 2. A plurality of annularly distributed cleaning scrapers 13 are provided on the inner ring of the scraper retainer 12. A connecting rod 3 is provided on one side of the top of the sleeve body 1. A lifting ring 4 is installed at one end of the connecting rod 3. A limiting crossbeam 5 is installed inside the lifting ring 4. A vehicle head connecting bracket 6 and an abutment head 7 are respectively installed at both ends of the limiting crossbeam 5.

[0022] The advantages of this solution are: it facilitates quick and easy installation onto the front bumper of a car, provides good installation stability, and allows for easy adjustment of the position of the sleeve body relative to the cleaning ring, making it easier to clean the outer wall surface of the sleeve body.
