Problems solved by technology

[0002] A bolt is a mechanical part, a cylindrical threaded fastener with a nut, a type of fastener consisting of a head and a screw. The screw is a cylinder with external threads and needs to be matched with a nut. It is used to fasten two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. ; At present, the traditional bolts and nuts are single structure, single structure, single function, in some special fields, such as nuclear facilities, aerospace and other fields, they will have various special requirements when using bolts and nuts, now Some bolts and nuts cannot meet their special requirements. This special requirement causes bolts and nuts to completely exceed the structure of bolts and nuts used in our general field and the form of mating connection. They are all redesigned and developed according to their special requirements. Manufactured to meet the special requirements for bolts and nuts in special fields; at present, a special connection requirement is encountered, which requires bolts to pass through a hollow wall panel, and the hollow wall panel is filled with gas. When the gas temperature in the hollow wall panel When rising, it is necessary to use bolts to automatically exhaust outwards. When the temperature of the gas in the hollow wall panel decreases, it is necessary to use bolts to automatically stop exhausting. At present, there are no bolts that can achieve the above functions, so the technical solution of the present invention is designed

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Such as Figure 1-4 Shown: This embodiment is a bolt with a heat-sensitive element, including a bolt 1 and an exhaust assembly. An axial exhaust hole 6 is arranged inside the screw of the bolt 1, and the outlet of the axial exhaust hole 6 is located far away from the screw. The screw end of the cap, the exhaust assembly includes a groove 2 arranged on the screw of the bolt 1, the groove 2 extends along the length direction of the screw of the bolt 1, the inner bottom of the groove 2 is provided with a radial exhaust hole 7, the groove 2. The radial exhaust hole 7 communicates with the axial exhaust hole 6; the inner two ends of the groove 2 are respectively provided with a pin shaft 3, and a bimetallic sheet 4 is connected between the two pin shafts 3, and the bimetallic sheet 4 The two ends of the two pin shafts 3 are respectively rotated and...

Abstract

The invention discloses a bolt with a heat-sensitive element, which includes a bolt and an exhaust assembly. An axial exhaust hole is arranged inside the screw rod of the bolt. The outlet of the axial exhaust hole is located at the end of the screw rod far away from the nut. The air assembly includes a groove arranged on the bolt screw, the groove extends along the length direction of the bolt screw, the inner bottom of the groove is provided with a radial exhaust hole, and the groove communicates with the axial exhaust hole through the radial exhaust hole ; The inner two ends of the groove are respectively provided with pin shafts, and a bimetallic sheet is connected between the two pin shafts. The two ends of the bimetallic sheet are respectively rotated and socketed on the two pin shafts. The corresponding bimetallic sheet is provided with a rubber plug for sealing the radial exhaust holes; the invention realizes that when the temperature of the gas in the hollow wall panel rises, the bolts can be used to automatically exhaust outwards; when the gas in the hollow wall panel When the temperature drops, the bolts can be used to automatically stop the exhaust; to meet the special requirements for bolts in special fields.
