[0003] However, in the existing technology, cars are prone to vibration during driving, which may cause parts to loosen due to vibration, leading to leakage of lubricating oil inside the transmission and affecting the normal operation of car parts. Therefore, a solution is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that vibrations can easily occur during vehicle operation, which may cause parts to loosen, leading to leakage of lubricating oil inside the transmission and thus affecting the normal operation of vehicle components.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-loosening sealing bolt for automotive transmissions, comprising: a bolt body; a threaded groove formed on the surface of the bolt body; and further comprising:

[0006] A threaded arc groove is formed on the surface of the threaded groove, and a rubber sealing strip is movably fitted on the surface of the threaded arc groove;

[0007] The mounting part is disposed on one end surface of the threaded groove, and a groove is formed on one side surface of the mounting part.

[0008] Preferably, a limiting groove is formed on the inner wall at the symmetrical location of the groove, and a spring is provided on the inner wall of the groove.

[0009] The technical effect of adopting the above-mentioned further solution is that the limiting groove opened inside the groove facilitates the limiting work of the parts, and at the same time the groove provides positioning support for the spring.

[0010] Preferably, a sealing ring is provided on one end surface of the spring, and the sealing ring is made of rubber.

[0011] The technical advantages of adopting the above-mentioned further solution are: the spring provides the ability to reset and position the sealing ring, making it convenient to use; at the same time, the sealing ring is made of rubber and has good oil resistance and high temperature resistance.

[0012] Preferably, the sealing ring is movably fitted onto the surface of the bolt body, and limit blocks are provided on the surface of the sealing ring at symmetrical locations.

[0013] The technical effect of adopting the above-mentioned further solution is that the bolt body provides a limiting function for the sealing ring, and when the sealing ring moves, it drives the limiting block to move as well.

[0014] Preferably, the two limiting blocks are slidably embedded inside the limiting groove, and a groove is opened on one side surface of the sealing ring.

[0015] The technical effect of adopting the above-mentioned further solution is that the limiting block is embedded in the limiting groove to provide limiting operation, and the sealing ring surface has a groove to facilitate the installation of internal parts.

[0016] Preferably, a gasket is movably embedded inside the groove, and the gasket is movably sleeved on the surface of the bolt body.

[0017] The technical advantage of adopting the above-mentioned further solution is that the gasket is installed along the bolt body through the groove, which facilitates the subsequent installation work.

[0018] Preferably, the surfaces of the gaskets at symmetrical locations are provided with triangular anti-slip blocks, and the two sets of triangular anti-slip blocks are oriented in opposite directions.

[0019] The technical effect of adopting the above-mentioned further solution is that when the triangular anti-slip block set on the surface of the gasket contacts the mounting surface, and the other end contacts the inner wall of the sealing ring, the friction is increased.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, when the mounting part is rotated with the help of a tool, the threaded groove on the surface of the bolt body is driven to engage with the corresponding parts. Before this, a rubber sealing strip is wrapped inside the threaded arc groove. The rubber sealing strip makes contact with the inner wall of the threaded arc groove and the mounting contact surface. The rubber sealing strip has the ability to deform, which increases the friction and provides a more stable installation effect.

[0022] 2. In this utility model, before installation, the gasket is fitted inside the groove along the bolt body. When the triangular anti-slip block on the surface of the gasket contacts the mounting surface, the gasket is squeezed along the inside of the groove. At the same time, the limiting block inside the groove moves along the inside of the limiting groove. With the reset and positioning provided by the spring, the more the bolt body rotates, the tighter the sealing ring contacts the contact surface, thus providing a sealing function. At the same time, there is no need to go through the installation work of multiple sealing gaskets and other auxiliary parts, making the operation simple. Attached Figure Description

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] Example 1, as Figure 1-4 As shown, this utility model provides an anti-loosening sealing bolt for automotive transmissions, comprising: a bolt body 1; a threaded groove 101 formed on the surface of the bolt body 1; further comprising: a threaded arc groove 1011 formed on the surface of the threaded groove 101, wherein a rubber sealing strip 1012 is movably fitted on the surface of the threaded arc groove 1011; and a mounting part 102 disposed on one end surface of the threaded groove 101, wherein a groove 1021 is formed on one side surface of the mounting part 102.

[0032] In this embodiment, when the mounting part 102 is rotated with the aid of a tool, the threaded groove 101 on the surface of the bolt body 1 is driven to thread and engage with the corresponding part. Before this, the rubber sealing strip 1012 is wrapped inside the threaded arc groove 1011. The rubber sealing strip 1012 makes contact with the inner wall of the threaded arc groove 1011 and the mounting contact surface. The rubber sealing strip 1012 has the ability to deform, which increases the friction and provides a more stable installation effect.

[0033] In Example 2, a limiting groove 1022 is formed on the inner wall of the groove 1021 at a symmetrical location. A spring 1023 is provided on the inner wall of the groove 1021. A sealing ring 1024 is provided on one end surface of the spring 1023. The sealing ring 1024 is made of rubber and is movably fitted on the surface of the bolt body 1. A limiting block 1025 is provided on the surface of the sealing ring 1024 at a symmetrical location. The two limiting blocks 1025 are slidably embedded in the limiting groove 1022. A slot 1026 is formed on one side surface of the sealing ring 1024. A gasket 1027 is movably embedded in the slot 1026 and is movably fitted on the surface of the bolt body 1. A triangular anti-slip block 1028 is provided on the surface of the gasket 1027 at a symmetrical location. The two sets of triangular anti-slip blocks 1028 are oriented in opposite directions.

[0034] In this embodiment, before installation, the gasket 1027 is fitted inside the slot 1026 along the bolt body 1. When the triangular anti-slip block 1028 on the surface of the gasket 1027 contacts the mounting surface, the gasket 1027 is squeezed along the inside of the slot 1026. At the same time, the limiting block 1025 inside the slot 1026 moves along the inside of the limiting groove 1022. With the reset and positioning provided by the spring 1023, the more the bolt body 1 rotates, the tighter the sealing ring 1024 contacts the contact surface, thereby providing a sealing function. At the same time, there is no need to go through the installation work of multiple sealing gaskets and other auxiliary parts, making the operation simple.

[0035] Working principle: During use, rotating the mounting part 102 with the aid of a tool causes the threaded groove 101 on the surface of the bolt body 1 to engage with the mating parts. Before this, a rubber sealing strip 1012 is wrapped around the inside of the threaded arc groove 1011. The rubber sealing strip 1012 achieves contact with the inner wall of the threaded arc groove 1011 and the mounting contact surface. The rubber sealing strip 1012 has deformation capability, increasing friction and providing a more stable installation effect. In addition, before installation, a washer 1027 is fitted along the bolt body 1 into the groove. Inside the slot 1026, when the triangular anti-slip block 1028 on the surface of the gasket 1027 contacts the mounting surface, the gasket 1027 is squeezed along the inside of the slot 1026. At the same time, the limiting block 1025 inside the slot 1026 moves along the inside of the limiting groove 1022. With the reset and positioning provided by the spring 1023, the more the bolt body 1 rotates, the tighter the sealing ring 1024 contacts the contact surface, thus providing a sealing function. At the same time, there is no need to go through the installation work of multiple sealing gaskets and other auxiliary parts, making the operation simple.

[0036] 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.
