Abstract
The invention relates to a self-locking sealing bolt which comprises a bolt body. The bolt body comprises a head, a middle section and a tail end, wherein the head is a pulling and screwing part, the middle section is a polish rod part, and the tail end is a threaded part. A sealing component is arranged at the joint between the pulling and screwing part and the polish rod part. The sealing component is provided with an annular groove in the joint between the pulling and screwing part and the polish rod part, and a sealing ring matched with the annular groove in outer diameter is embedded in the annular groove. The threaded part is provided with a self-locking device. The self-locking device is evenly provided with 4-6 blind holes in the end face of the threaded part. The depth of each blind hole is one half to three quarters of the length of the threaded part. An elastic element is embedded in each blind hole. The self-locking sealing bolt is simple in structure, convenient and fast to install, stable in self-locking performance, high in vibration resistance, stable in sealing performance and suitable for working environments with different media.
Description
Technical field
The invention belongs to mechanical manufacturing field, specifically relate to a kind of self locking type sealing bolt.
Background technique
Bolt is mechanical connection manner conventional in prior art, be widely used in various machinery industry, as industries such as Aeronautics and Astronautics, boats and ships, high ferros, but having many casings and cover board connection structure to need some to have self-locking structure in machinery industry has again the bolt of sealability to be connected, and these connections often need multiple part to complete self-locking and sealing, and require good anti-vibration, locking, decay resistance, also will be convenient to quick mounting, dismounting.And can not meet for existing plain bolt the usage requirement that this type of casing is connected with cover plate, therefore how to develop a kind of high-low temperature resistant, good seal performance, and install, the self-locking screw of convenient disassembly, be current problem demanding prompt solution.
Summary of the invention
The technology that the present invention will solve is for the deficiencies in the prior art, provide a kind of structure simply to have bolt that self-locking structure has again sealability, specifically a kind of self locking type sealing bolt.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of self locking type sealing bolt, comprise bolt body, described bolt body comprises head, intermediate section, tail end three part, head is twisting portion, intermediate section is polished rod portion, tail end is screw section, described twisting portion and jointing place, polished rod portion are provided with sealed member, described sealed member is that described twisting portion and jointing place, polished rod portion are provided with annular groove, and the seal ring matched with described annular groove external diameter is embedded at described annular groove, described screw section is provided with self-locking device, described self-locking device is for be provided with 4 ~ 6 blind holes equably at described screw section end face, the degree of depth of described blind hole is 3/1 to four/2nds of flighted length, flexible is embedded in described blind hole.
Further, described blind hole is set to 4.
Further, the elastic component be embedded in described blind hole is that polytetrafluoroethylmaterial material makes.
Further, described seal ring adopts silicone rubber to make.
Adopt a kind of self locking type sealing bolt of the present invention, its beneficial effect is: owing to being provided with sealed member and self-locking device, substantially increase the locking functions of bolt, have very strong shock resistance, also there is seal action, can prevent due to housing environment change and produce leakage accident.Structure of the present invention is simple, quick and easy for installation, has stable self-locking property, and freedom from vibration is strong, and sealability is stablized, and is applicable to the working environment of different medium.Have very high application prospect, especially the installation of Aero-Space and the equipment part such as machinery industry hydraulic pressure or air pressure parts can be widelyd popularize, and has good economic benefit and social benefit.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the left diagram of Fig. 1.
Shown in figure: 1-twisting portion, 2-polished rod portion, 3-screw section, 4-groove, 5-seal ring, 6-blind hole, 7-elastic component.
Embodiment
As depicted in figs. 1 and 2, a kind of self locking type sealing bolt of the present invention, comprise bolt body, described bolt body comprises head, intermediate section, tail end three part, head is twisting portion 1, intermediate section is polished rod portion 2, tail end is screw section 3, in described twisting portion 1, jointing place, polished rod portion 2 is provided with sealed member, described sealed member is, in described twisting portion 1, jointing place, polished rod portion 2 is provided with annular groove 4, and the seal ring 5 matched with described annular groove 4 external diameter is embedded at described annular groove 4, described screw section 3 is provided with self-locking device, described self-locking device is for be provided with 4 ~ 6 blind holes 6 equably at described screw section 3 end face, the degree of depth of described blind hole 6 is 3/1 to four/2nds of screw section 3 length, flexible 7 is embedded in described blind hole 6.
Further, described blind hole 6 is set to 4.
Further, the elastic component 7 be embedded in described blind hole 6 is polytetrafluoroethylmaterial material making.
Further, described seal ring 5 adopts silicone rubber to make.
In actual fabrication process, different metal can be selected as bolt body material according to different needs, owing to selecting silicone rubber O-ring 5 as sealing part, have good high temperature resistant conjunction and decay resistance, the scope that conforms is wide.Blind hole 6 set by screw section 3 is embedded in elastic component 7, described elastic component 7 adopts polytetrafluoroethylmaterial material to be formed to have the self-locking device of self-locking structure, and during installation, self-locking device reaches good self-locking effect by the elasticity of polytetrafluoroethylmaterial material self and corrosion resistance.
Adopt a kind of self locking type sealing bolt of the present invention, quick and easy for installation, have stable self-locking property, freedom from vibration is strong, and sealability is stablized, and is applicable to the working environment of different medium.Have very high application prospect, especially the installation of Aero-Space and the equipment part such as machinery industry hydraulic pressure or air pressure parts can be widelyd popularize, and has good economic benefit and social benefit.
Protection scope of the present invention is not limited only to the technological scheme disclosed in embodiment; the foregoing is only better embodiment of the present invention; not in order to limit the present invention; every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
