Embodiment 1

[0041] see Figure 1-3 , the present invention provides a technical solution: a fastener for nuclear power plants, specifically comprising:

[0042] Fixed cap 1, the fixed cap 1 has the main body of the round table, and the cross embedded groove 2 provided on the top of the main body of the round table, and the fixed bolt rod 3 fixed at the middle position of the bottom of the main body of the round table, and the one end of the fixed bolt rod 3 away from the main body of the round table. The pasting mechanism 4, through the design of the pasting mechanism 4 itself, when the fastener fails during use, the pasting mechanism 4 of the fastener can be directly destroyed by an external device, so as to realize the overall replacement of the fastener. To avoid contact between personnel and the inside of the components, and to avoid the radiation of the nuclear power plant from causing harm to personnel safety, the pasting mechanism 4 includes:

[0043] Transmission mechanism 41, the ...

Embodiment 2

[0047] see Figure 1-5 On the basis of Embodiment 1, the present invention provides a technical solution: the transmission mechanism 41 includes:

[0048] Transmission rod 411, the transmission rod 411 has an externally threaded cylinder rod, and an air bag 412 installed in the inner cavity of the externally threaded cylinder rod, and a ring plate 413 installed at the middle and lower position of the outer surface of the externally threaded cylinder rod, and installed outside the ring plate 413 The air pressure column 414 on the surface, and the ventilation pores 415 provided in the middle position of the external thread cylinder rod and the ring plate 413 . The design of the air pressure column 414 protects the sealing pressure plate 45 and the sealing bottom plate 42 to avoid damage caused by excessive stress concentration caused by excessive deformation. At the same time, the elasticity of the air pressure column 414 affects the shape of the components of the sealing pressu...

Embodiment 3

[0056] see Figure 1-6 , on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the fixed bolt 3 includes:

[0057] Bolt rod 31, this bolt rod 31 has thread cylinder, and the end plate 32 that is installed on the outer surface of thread cylinder, and is installed between end plate 32 and is positioned at the placement cylinder 33 of thread cylinder outside, and is opened in placement cylinder 33 There are annular grooves 34 on the inner surface and the outer surface, and capillary holes 35 provided on the outer surface of the placement cylinder 33 and between the annular grooves 34 . The secondary filling and sealing of the expansion sealing material is carried out by placing the cylinder 33, and at the same time, the self-protection ability of the fastener is promoted, the external environment is isolated, the penetration of external substances is avoided, and the service life of the component is extended and protected.

Abstract

The invention discloses a fastener for a nuclear power station. The fastener specifically comprises a pasting mechanism mounted at the end, away from a circular truncated cone main body, of a fixing bolt rod. The pasting mechanism comprises a transmission mechanism. The transmission mechanism is provided with a columnar main body, a sealing bottom plate mounted at the bottom of the outer surface of the columnar main body, gap-reserved strip plates mounted on the outer surface of the sealing bottom plate, overflow holes formed in the outer surface of the sealing bottom plate and located between the gap-reserved strip plates, and a sealing pressure applying plate mounted at the top of the outer surface of the columnar main body. The invention relates to the technical field of fasteners. Through the design of the pasting mechanism, when the fastener loses efficacy in the using process, the pasting mechanism of the fastener can be directly damaged through an external device, overall replacement of the fastener is achieved, personnel are prevented from making contact with the interiors of components, and the circumstance that radiation of the nuclear power station causes harm to personnel safety is avoided.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a fastener for nuclear power plants. Background technique [0002] A fastener assembly may be used to secure a first component, such as a sheet metal or panel, to a second component, such as a trim molding. More specifically, a female fastening member in a fastener assembly may, for example, be pushed into a groove in a panel. The male fastening member can thus, for example, be connected to the trim molding and locked into the female fastening member, which results in a fastened structure. [0003] According to Chinese patent CN110939635A, the barrel is configured to engage and be secured to a slot in the chassis, wherein the barrel is configured to include at least two or more protrusions based on The barrel is secured to the slot, wherein the tabs are attached to the barrel along the top of each of the tabs, and wherein the tabs are configured to The top of the protrusion ...
