Description

Technical Field

[0001] This application relates to the technical field of dust covers, and particularly relates to a dust cover that prevents falling off. Background Art

[0002] In the patent with the published authorization announcement number CN212106694U, a TPE dust cover is disclosed, which relates to the technical field of automotive parts. It includes a large-port ring, a small-port ring, and a corrugated section. The corrugated section is located between the large-port ring and the small-port ring. At least one interference part is provided on the inner wall of the large-port ring. A positioning groove is also provided on the large-port ring. The positioning groove penetrates the outer wall of the large-port ring and corresponds to the interference part. This patent can effectively reduce the risk of the clamp disengaging and slipping during use.

[0003] For the TPE dust cover in the above patent, since the ring body of the large-port ring is relatively weak, after being used for a certain period, due to the long-term fastening of the clamp, the pressure causes indentations on the large-port ring, resulting in cracks and splits. Furthermore, not only does it accelerate the service life of the dust cover, but it also requires regular replacement and disassembly, which is time-consuming and laborious.

[0004] Therefore, this application proposes a dust cover that prevents falling off. Utility Model Content

[0005] A dust cover that prevents falling off proposed by this application is used to solve the problems raised in the above background art. By setting a protection mechanism, a rubber ring and sealant, the rubber ring is fixedly connected to the large-port ring through the sealant. It can not only protect the large-port ring from being damaged during use, but also increase the sealing performance between the dust cover body and the drive shaft. Thus, it ensures the use effect of the dust cover body, and further improves the service life of the dust cover body, eliminating the need for regular replacement of the dust cover body, thereby reducing cost expenditures and greatly enhancing the practicality of the device.

[0006] To achieve the above object, this application adopts the following technical solutions:

[0007] A dust cover that prevents falling off includes a dust cover body. The dust cover body is composed of a large-port ring, a small-port ring, and a corrugated section. The corrugated section is arranged between the large-port ring and the small-port ring. A protection mechanism is provided outside the large-port ring. The protection mechanism includes a rubber ring and sealant. The rubber ring is sleeved outside the large-port ring, and sealant is provided between the large-port ring and the rubber ring.

[0008] As a preferred embodiment, a reinforcement mechanism is provided inside the large-port ring and the rubber ring. The reinforcement mechanism includes through holes and arc-shaped rubber blocks. The two through holes are both opened inside the large-port ring and the rubber ring. The two arc-shaped rubber blocks are both arranged in the through holes inside the rubber ring. Reinforcement rods are rotatably connected inside the two arc-shaped rubber blocks, and fixed blocks are fixedly connected to one ends of the two reinforcement rods away from the arc-shaped rubber blocks;

[0009] By holding the fixed block and rotating it clockwise, the reinforcement rod is urged to extend into the through hole. At this time, the arc-shaped rubber block contacts the drive shaft. Through continuous extension of the reinforcement rod, the two arc-shaped rubber blocks will exert pressure on the drive shaft, achieving a fastening effect, thereby improving the practicability of the device.

[0010] As a preferred embodiment, connection mechanisms are provided between the two through holes and the reinforcement rods. The connection mechanisms include first threads and second threads. The two first threads are both arranged on the outer part of the reinforcement rods. The second threads are both arranged inside the two through holes, and the two reinforcement rods are threadedly connected to the through holes through the first threads and the second threads;

[0011] By providing the connection mechanisms, the first threads and the second threads, a connection is formed between the reinforcement rod and the through hole, achieving a fixing effect, thereby improving the practicability of the device.

[0012] As a preferred embodiment, slot hole mechanisms are provided inside the two fixed blocks. The slot hole mechanisms include installation slots and movable slots. The two installation slots and the movable slots are both opened inside the fixed blocks, and the two installation slots and the movable slots are communicated with each other;

[0013] By providing the slot hole mechanisms, the installation slots and the movable slots, it is convenient to install the positioning parts, enabling the positioning parts to have a space for movement, thereby improving the practicability of the device.

[0014] As a preferred embodiment, limiting mechanisms are provided inside the two installation slots. The limiting mechanisms include limiting slide rods. The two limiting slide rods are both fixedly connected inside the installation slots. Springs are arranged on the outer parts of the two limiting slide rods, and a plurality of limiting convex blocks are arranged at both ends of the springs on the outer parts of the two limiting slide rods;

[0015] Through the spring reset, the two L-shaped positioning rods are urged to slide on the outer part of the limiting slide rod towards the direction of the limiting convex blocks, thereby improving the practicability of the device.

[0016] As a preferred embodiment, positioning mechanisms are provided inside both of the installation grooves. The positioning mechanism includes positioning grooves, each of which is opened inside the rubber ring sleeve. A plurality of L-shaped positioning rods are slidably connected to the outer sides of the two limiting sliding rods, and one end of each L-shaped positioning rod extends into the positioning groove. One side of each L-shaped positioning rod away from the limiting convex block is fixedly connected to one end of a spring;

[0017] By automatically extending the L-shaped positioning rods into the positioning grooves, the positioning effect is achieved. In this way, the problem that the dust-proof cover body may fall off during use is prevented, thereby improving the practicality of the device.

[0018] Advantages of the present application:

[0019] 1. The dust-proof cover with anti-dropping function of the present application is provided with a protection mechanism, a rubber ring sleeve and sealant. The rubber ring sleeve is fixedly connected to the large port ring through the sealant, which can not only protect the large port ring from being damaged during use, but also increase the sealing performance of the connection between the dust-proof cover body and the drive shaft. Thus, the use effect of the dust-proof cover body is ensured, and further, the service life of the dust-proof cover body is extended. There is no need to regularly replace the dust-proof cover body, thereby reducing cost expenditure and greatly improving the practicality of the device;

[0020] 2. For the dust-proof cover with anti-dropping function of the present application, when the rubber ring sleeve is located on the drive shaft, hold the fixed block and rotate it clockwise. Through the cooperation of the first thread and the second thread, the reinforcement rod extends into the through hole. At this time, the arc-shaped rubber block contacts the drive shaft. By continuously extending the reinforcement rod, the two arc-shaped rubber blocks will form a pressure on the drive shaft to achieve a tightening effect. When the fixed block is located inside the through hole, at this time, through the spring reset, the two L-shaped positioning rods slide on the outer side of the limiting sliding rod towards the direction of the limiting convex block, so that the L-shaped positioning rods automatically extend into the positioning grooves to achieve the positioning effect. In this way, the problem that the dust-proof cover body may fall off during use is prevented, and the practicality of the device is greatly improved. Description of the Drawings
