Description
Technical field
The invention belongs to mechanical manufacturing field, specifically relate to a kind of self-locking type sealing bolt.
Background technology
Bolt is mechanical connection manner conventional in prior art, be widely used in various machinery industries, as industries such as Aeronautics and Astronautics, boats and ships, high ferros, but in machinery industry, having many casings and cover board connection structure to need some to have self-locking structure has again the bolt of sealing property to be connected, and these connections often need multiple parts to complete self-locking and sealing, and requiring has good anti-vibration, locking, decay resistance, also will be convenient to Fast Installation, dismounting. And can not meet for existing plain bolt the instructions for use that this type of casing is connected with cover plate, and therefore how to develop a kind of high-low temperature resistant, good seal performance, and the self-locking screw of installation, 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, provides a kind of and simple in structurely has self-locking structure and have again the bolt of sealing property, 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, interlude, tail end three parts, head is twisting portion, interlude is polished rod portion, tail end is threaded portion, be provided with seal member in described twisting portion and polished rod portion junction, described seal member is to be provided with annular groove in described twisting portion and polished rod portion junction, and be embedded in the sealing ring matching with described annular groove external diameter at described annular groove, be provided with self-locking device in described threaded portion, described self-locking device is for to be provided with equably 4～6 blind holes at described threaded portion end face, the degree of depth of described blind hole is 1/2nd to 3/4ths of flighted length, be embedded in flexible in described blind hole.
Further, described blind hole is set to 4.
Further, the elastic component being embedded in described blind hole is that polytetrafluoroethylmaterial material is made.
Further, described sealing ring adopts silicon 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 seal member and self-locking device, greatly improved the locking functions of bolt, had very strong shock resistance, also there is sealing function, can prevent because casing environmental change produces leakage accident. The present invention is simple in structure, quick and easy for installation, has stable self-locking property, and freedom from vibration is strong, and sealing property is stable, applicable to the working environment of different medium. Have very high application prospect, especially the installation of the equipment part such as Aero-Space and plant equipment industry hydraulic pressure or air pressure parts can be widelyd popularize, and has good economic benefit and social benefit.
Brief description of the drawings
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-threaded portion, 4-groove, 5-sealing ring, 6-blind hole, 7-elastic component.
Detailed description of the invention
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, interlude, tail end three parts, head is twisting portion 1, interlude is polished rod portion 2, tail end is threaded portion 3, be provided with seal member in described twisting portion 1 and polished rod portion 2 junctions, described seal member is to be provided with annular groove 4 in described twisting portion 1 and polished rod portion 2 junctions, and be embedded in the sealing ring 5 matching with described annular groove 4 external diameters at described annular groove 4, be provided with self-locking device in described threaded portion 3, described self-locking device is for to be provided with equably 4～6 blind holes 6 at described threaded portion 3 end faces, the degree of depth of described blind hole 6 is 1/2nd to 3/4ths of threaded portion 3 length, be embedded in flexible 7 in described blind hole 6.
Further, described blind hole 6 is set to 4.
Further, the elastic component 7 being embedded in described blind hole 6 is polytetrafluoroethylmaterial material making.
Further, described sealing ring 5 adopts silicon rubber to make.
In actual fabrication process, can need to select different metal as bolt body material according to different, owing to selecting silicone rubber O-ring 5 as sealing part, there is well high temperature resistant closing and decay resistance, the scope that conforms is wide. The blind hole 6 set in threaded portion 3 is embedded in elastic component 7, it is to form the self-locking device with self-locking structure that described elastic component 7 adopts polytetrafluoroethylmaterial material, and when installation, self-locking device reaches good self-locking effect by elasticity and the corrosion resistance of polytetrafluoroethylmaterial material self.
Adopt a kind of self-locking type sealing bolt of the present invention, quick and easy for installation, there is stable self-locking property, freedom from vibration is strong, and sealing property is stable, applicable to the working environment of different medium. Have very high application prospect, especially the installation of the equipment part such as Aero-Space and plant equipment 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 disclosed technical scheme of detailed description of the invention; the foregoing is only preferred embodiments of the present invention; not in order to limit the present invention; any trickle amendment that every foundation technical spirit of the present invention is done above embodiment, be equal to and replace and improve, within all should being included in the protection domain of technical solution of the present invention.
