In order to achieve the technical purpose, the utility model adopts the following technical scheme:
a damping bolt assembly integrated with a damping gasket comprises a bolt, wherein an annular boss is arranged in the middle of a stud of the bolt, a stud section between the annular boss of the bolt and a bolt head is a gasket sleeved stud section, a stud section between the annular boss of the bolt and the bottom end of the stud is a threaded stud section, and threads are arranged on the threaded stud section; the damping bolt assembly further comprises a damping gasket, the damping gasket is sleeved on the stud of the bolt and located at the stud sleeved section, the inner diameter of the damping gasket is smaller than the outer diameter of the annular boss, and the damping gasket has tensile elasticity.
Further, the shock attenuation bolt subassembly still includes the protection gasket, the protection gasket suit is on the double-screw bolt of bolt, and the protection gasket is located gasket suit double-screw bolt section department, and the protection gasket is located between the bolt head and the shock attenuation gasket of bolt, and the internal diameter of protection gasket is greater than the external diameter of cyclic annular boss.
Further, the gasket sleeved stud section is a smooth surface.
Further, the shock absorption gasket is a rubber gasket.
Further, the protective gasket is a steel gasket.
Compared with the prior art, the damping bolt assembly has the beneficial effects that: in the shock-absorbing bolt assembly, the shock-absorbing gasket and the protective gasket are limited at the gasket sleeving stud section by the annular boss arranged in the middle of the stud of the bolt, so that the shock-absorbing gasket and the protective gasket cannot fall off from the bolt, and the bolt, the shock-absorbing gasket and the protective gasket are integrated together to form the shock-absorbing bolt assembly, so that the shock-absorbing bolt assembly is convenient to purchase, transport and store, saves material resources, and can be used after being taken out when being used and installed, thereby omitting the process of sleeving the gasket by the bolt, and greatly improving the working efficiency.
Drawings
Fig. 1 is a schematic structural view of a shock bolt assembly integrated with a shock-absorbing gasket according to the present invention.
In the figure: 1-bolt, 11-annular boss, 12-gasket sleeved stud section, 13-threaded stud section, 2-damping gasket and 3-protective gasket.
Detailed Description
The utility model will be further described with reference to the following drawings and specific examples:
the embodiment is a damper bolt assembly integrated with a damper gasket, and the damper bolt assembly of the embodiment is used for fixing and mounting a cylinder head housing of an engine.
Referring to fig. 1, the damper bolt assembly of the present embodiment includes a bolt 1 and a damper shim 2.
The middle part of the stud of the bolt 1 is provided with an annular boss 11, the stud of the bolt 1 is divided into two sections by the annular boss 11, wherein the stud section between the annular boss 11 of the bolt 1 and the bolt head is a gasket sleeved stud section 12, the gasket sleeved stud section 12 is a smooth surface, the stud section between the annular boss 11 of the bolt 1 and the bottom end of the stud is a threaded stud section 13, and threads are arranged on the threaded stud section 13. The damping gasket 2 is sleeved on a stud of the bolt 1 and located at a position where the gasket is sleeved with a stud section 12, the inner diameter of the damping gasket 2 is required to be smaller than the outer diameter of the annular boss 11, and the damping gasket 2 has tensile elasticity. The annular boss 11 of the bolt 1 can limit the damping gasket 2 at the position where the gasket is sleeved with the bolt column section 12, and the damping gasket 2 cannot fall off from the bolt 1.
Further optimally, the damping bolt assembly of the embodiment further comprises a protective gasket 3, the protective gasket 3 is sleeved on the stud of the bolt 1 and located at the position of the gasket sleeved bolt section 12, the protective gasket 3 is located between the bolt head of the bolt 1 and the damping gasket 2, and the inner diameter of the protective gasket 3 needs to be larger than the outer diameter of the annular boss 11 so as to facilitate installation. Set up the purpose of protection gasket 3 and keep apart bolt 1's bolt head and damping gasket 2, when screwing up bolt 1, damping gasket 2 then can not with bolt 1's bolt head direct contact, and protection gasket 3 has played the guard action to damping gasket 2, prevents that it from receiving the rotation of bolt head to roll and wearing and tearing.
In the present embodiment, the damping washer 2 is a rubber washer, and the protective washer 3 is a steel washer.
When the damping bolt assembly of the embodiment is assembled, the protective gasket 3 is firstly sleeved at the gasket sleeved stud section 12, and then the damping gasket 2 is sleeved at the gasket sleeved stud section 12. When the protective gasket 3 is fitted, the inner diameter of the protective gasket 3 is larger than the outer diameter of the annular boss 11, and therefore, the protective gasket does not obstruct the passage of the annular boss 11. When the damping shim 2 is sleeved, the damping shim 2 has tensile elasticity, so that the damping shim 2 can be stretched to increase the inner diameter and then pass through the annular boss 11. After the damper bolt assembly is assembled, since the protective washer 3 is located between the bolt head of the bolt 1 and the damper washer 2, even if the inner diameter thereof is larger than the outer diameter of the annular boss 11, the protective washer 3 does not fall down under the restriction of the damper washer 2.
In the shock-absorbing bolt assembly of this embodiment, the cyclic annular boss 11 that the double-screw bolt middle part of bolt 1 set up all restricts shock-absorbing gasket 2 and protection gasket 3 in gasket suit stud section 12 department, then shock-absorbing gasket 2 and protection gasket 3 can not drop from bolt 1, and bolt 1, shock-absorbing gasket 2 and protection gasket 3 are integrated jointly and have constituted the shock-absorbing bolt assembly to be convenient for purchase, transportation, storage, and use installation.
In addition, for the bolt 1 in the vibration-damping bolt assembly of the present embodiment, in order to improve the bolt processing and manufacturing efficiency, the bolt 1 is manufactured by adopting a die cold heading forming manner, and the annular boss 11 is integrally formed with the bolt 1 in the cold heading forming process, so that excessive processing procedures are not required, and the realization is simple and convenient.
In other embodiments, the shock bolt assembly according to the present invention may be used for mounting and fixing various mechanical devices requiring shock absorption and noise reduction. When using this shock attenuation bolt subassembly, take to come the usefulness, left out the process of bolt suit gasket to work efficiency has been promoted greatly.
