Technical Field
The utility model belongs to the technical field of explosion-proof safety, especially, relate to a let out and explode bolt for letting out explosion door.
Background
Let out the explosion door and generally include two cold-rolled steel sheets and locate the fireproof material layer between two cold-rolled steel sheets, let out explosion door one side and be equipped with adjustable door-hinge, it is equipped with a plurality of windows of letting out to let out to explode on the explosion door, let out to explode and be equipped with on the window and let out and explode the bolt, when being equipped with the indoor unexpected explosion that takes place of this let out explosion door, when pressure reaches the pressure value of letting out and exploding of predesigned, let out and explode the window and open in the bolt department of letting out easily, outwards excrete explosion pressure rapidly, and then avoided the huge loss of indoor personnel's life and property.
The invention patent application No. 200810180526.7 discloses an explosion venting bolt fastener for an explosion venting facility, which can enhance the strength of the explosion venting bolt fastener without increasing the thickness and simultaneously enhance the waterproof effect of the explosion venting bolt fastener. The screw rod comprises a screw rod and a metal gasket sleeved at the head of the screw rod, an elastic gasket arranged on the screw rod is sleeved under the metal gasket, and the metal gasket is of an arc-shaped structure protruding outwards. The elastic gasket has the same arc-shaped structure as the metal gasket and is tightly attached to the lower part of the metal gasket. The arc-shaped structure can adopt a spherical surface structure. The elastic gasket can be a rubber gasket. The end of the screw is provided with a self-tapping head. The thread surface layer of the screw is plated with an anti-corrosion rust layer.
However, if the explosion venting bolt fastener with the structure is adopted on the explosion venting window of the explosion venting door, the metal gasket and the nut are exposed outside the mounting hole formed on the window leaf, and the high bulges of the metal gasket and the nut are not beautiful. Therefore, the explosion venting bolt which can be completely installed in the installation holes formed in the window frame and the window leaf needs to be designed, so that the explosion venting bolt and the explosion venting door are integrated into a whole, and the appearance is more attractive; in addition, the metal gasket is of an arc-shaped structure protruding outwards, and is not easy to damage under the condition of low explosion pressure.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: the utility model provides a let out and explode bolt for letting out explosion vent, aim at letting out and explode the bolt and can install the mounting hole of seting up on the explosion vent completely to make let out and explode bolt and let out the explosion vent and combine together, more pleasing to the eye, the gasket destroys more easily simultaneously, uses under the less condition of suitable explosion pressure.
The utility model adopts the technical scheme as follows:
an explosion venting bolt for an explosion venting door. The explosion venting bolt for an explosion venting door comprises: the screw rod and with the sleeve pipe that the screw rod cover was established, the length of screw rod is greater than sheathed tube length, the screw rod exposes sheathed tube part is provided with the screw thread, the sleeve pipe surface is provided with the screw thread, be provided with heavy groove on the tip top surface of screw rod, the tip side fixedly connected with gasket of screw rod, the outer fringe of gasket with sheathed tube terminal surface fixed connection, the diameter more than or equal to of gasket sheathed tube internal diameter less than or equal to sheathed tube external diameter, the gasket be to the bellied arc structure of sleeve pipe direction.
Among the above-mentioned technical scheme, install on letting out the explosion door the utility model discloses a when letting out the explosion bolt, will let out the explosion bolt pack into let out in the window frame of exploding the window and the mounting hole of seting up on the window page or leaf, through cross or a word instrument sword with the heavy groove that sets up on the tip top surface of screw rod cooperatees, will sleeve pipe and window page or leaf threaded connection, screw rod and window frame threaded connection for window frame and window page or leaf are together fixed. Because the diameter of the gasket is more than or equal to the inner diameter of the sleeve and less than or equal to the outer diameter of the sleeve, the whole explosion venting bolt can be immersed into the mounting holes formed in the window frame and the window leaf.
