Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1-4: the embodiment is a bolt with a thermosensitive element, which comprises a bolt 1 and an exhaust assembly, wherein an axial exhaust hole 6 is arranged in a screw rod of the bolt 1, an outlet of the axial exhaust hole 6 is positioned at the end part of the screw rod far away from a nut, the exhaust assembly comprises a groove 2 arranged on the screw rod of the bolt 1, the groove 2 extends along the length direction of the screw rod of the bolt 1, a radial exhaust hole 7 is arranged at the inner bottom part of the groove 2, and the groove 2 is communicated with the axial exhaust hole 6 through the radial exhaust hole 7; the inside both ends of recess 2 are provided with round pin axle 3 respectively, are connected with bimetallic strip 4 between two round pin axles 3, and the both ends of bimetallic strip 4 rotate respectively and cup joint on two round pin axles 3, are provided with the rubber buffer 5 that is used for shutoff radial exhaust hole 7 on bimetallic strip 4 that corresponds with radial exhaust hole 7.
In the embodiment, two exhaust assemblies are arranged and are respectively positioned on two sides of the screw rod of the bolt 1; in practical application, the exhaust assemblies can also be provided in plurality, and the exhaust assemblies are uniformly and circumferentially arranged on the screw rod of the bolt 1.
The bimetallic strip 4 in this embodiment is an arc-shaped structure, and the inner bottom of the groove 2 is an arc-shaped surface matched with the bimetallic strip 4 with the arc-shaped structure.
In this embodiment, the rubber plug 5 is a cylindrical structure, and the diameter of the cylindrical structure rubber plug 5 is greater than the diameter of the radial vent hole 7; the rubber stopper 5 is convenient to block the radial exhaust hole 7.
In this embodiment, rubber buffer 5's top is spherical structure, and the radial exhaust hole 7 of shutoff that makes rubber buffer 5's top can be better.
In the embodiment, a connecting part 11 matched with an external component is formed at the end part of the screw rod far away from the screw cap, the diameter of the connecting part 11 is smaller than that of the screw rod, and an inclined-plane step structure is formed between the connecting part 11 and the screw rod; the outer circumference of the connecting part 11 is formed with a screw thread which is matched and connected with an external component; in practical application, the outer circumferential surface of the connecting portion 11 may also be provided with an annular clamping groove for matching and connecting with an external component; so that the screw rod of the bolt 1 can be better matched and connected with an external part.
The working principle of the embodiment is as follows:
the bimetallic strip is a composite material composed of two metals or other materials with appropriate properties; the bimetallic strip is also called as a thermal bimetallic strip, and because the thermal expansion coefficients of all component layers are different, when the temperature changes, the deformation of the active layer is larger than that of the passive layer, so that the whole bimetallic strip can bend towards one side of the passive layer, and the curvature of the composite material changes to generate deformation; in the embodiment, the bolt 1 is arranged on the hollow wallboard 9 and is locked by the nut 8, and at the moment, the exhaust component on the screw rod of the bolt 1 is just positioned at the hollow position of the hollow wallboard 9; in a normal state, namely when the temperature of gas in the hollow wallboard 9 is lower, the bimetallic strip 4 is in an initial state, and the rubber plug 5 on the bimetallic strip 4 blocks the radial vent hole 7; in an abnormal state, namely when the temperature of the gas in the hollow wallboard 9 is increased, the bimetallic strip 4 is heated to deform, the rubber plug 5 on the bimetallic strip 4 does not block the radial vent hole 7 any more, and the gas in the hollow wallboard 9 is exhausted outwards through the radial vent hole 7 and the axial vent hole 6; when the temperature of the gas in the hollow wall plate 9 is reduced, the bimetallic strip 4 deforms again and returns to the initial state, and the gas in the hollow wall plate 9 stops exhausting outwards.
The invention realizes that when the temperature of the gas in the hollow wallboard rises, the gas can be automatically exhausted outwards by utilizing the bolt; when the temperature of the gas in the hollow wallboard is reduced, the gas can be automatically stopped to exhaust by utilizing the bolts; and the special requirements of special fields on the bolt are met.
The above description is only a preferred embodiment of the present patent, and it should be noted that, for those skilled in the art, several modifications and decorations can be made without departing from the inventive concept, and these modifications and decorations should also be regarded as the protection scope of the present patent.
