Abstract
The utility model relates to a tyre explosion prevention device, which is characterized in that the tyre explosion prevention device comprises a bracket, a threaded bolt, a square pressure cap, a gas nipple and a valve needle pressure cap; the upper end of the threaded bolt is fixed to the bracket, a nut is arranged at the middle part of the threaded bolt, and the lower end thereof is connected with the square pressure cap; the nut is connected with the square pressure cap through a spring; the gas nipple is positioned under the square pressure cap and is fixed on the barrel-shaped inner wall at the lower part of the bracket in a sealing manner; the valve needle pressure cap is arranged on the bracket through a connecting bar. The tyre explosion prevention device has the beneficial effects of simple structure and convenient use, automatically deflates when the tyre pressure is increased, automatically shuts down when the tyre internal pressure is normal, and further prolongs the service life of the tyre.
Description
(1) technical field
The invention belongs to tyre accessories, particularly a kind of tyre explosion-proof equipment.
(2) background technique
Tire is friction for a long time at high temperature, tire pressure is raise greatly, so that blow out, and vehicle is stopped, and brings about great losses.
(3) summary of the invention
The present invention is in order to remedy the deficiencies in the prior art, provide a kind of easy to use, can prolong the tire tyre explosion-proof equipment in working life.
The present invention is achieved through the following technical solutions:
Tyre explosion-proof equipment of the present invention, its special way is: comprise support, bolt, square pressure cap, valve, plunger pressure cap, the bolt upper end is fixed on the support, the middle part is equipped with a nut, the side of being connected, lower end pressure cap, nut is by spring connecting part pressure cap, and the valve side of being positioned at pressure cap below and sealing and fixing are on the tubular inwall of support bottom, and the plunger pressure cap is rack-mount by connecting rod.
Tyre explosion-proof equipment of the present invention moves up and down for the ease of square pressure cap, the bolt boring, and square pressure cap is plugged in the bolt by the bar at top.
Tyre explosion-proof equipment of the present invention, square pressure cap bottom is provided with the packing ring corresponding with valve, can make between the two to seal.
Tyre explosion-proof equipment of the present invention, in order to prevent to touch, support top is with the explosion-proof device cap.
Tyre explosion-proof equipment of the present invention in order to prevent to damage by pressure plunger, makes Elastic Contact between plunger pressure cap and the plunger, is provided with spring between plunger pressure cap and the support.
Be provided with the inclined-plane nylon spacer that is used to seal around the tyre explosion-proof equipment of the present invention, the connecting rod of valve.
The invention has the beneficial effects as follows, simple in structure, easy to use, can be when tire pressure raises automatic vent, the tire internal air pressure is just often closed automatically, thereby prolongs the working life of tire.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is an internal structure schematic representation of the present invention, and Fig. 2 is a profile schematic representation of the present invention.
Among the figure, 1 explosion-proof device cap, 2 connecting rods, 3 bolts, 4 nuts, 5 springs, 6 side's pressure caps, 7 packing rings, 8 valves, 9 inclined-plane nylon spacers, 10 connecting rods, 11 springs, 12 plunger pressure caps, 13 screw threads.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.
Tyre explosion-proof equipment of the present invention, comprise support, bolt 3, square pressure cap 6, valve 8, plunger pressure cap 12, the bolt upper end is fixed on the support, the middle part is equipped with a nut 4, the side of being connected, lower end pressure cap, nut is by spring 5 connecting part's pressure caps, and the valve side of being positioned at pressure cap below and sealing and fixing are on the tubular inwall of support bottom, and the plunger pressure cap is rack-mount by connecting rod 10.The bolt boring, square pressure cap is plugged in the bolt by the connecting rod 2 at top.Pressure cap bottom, side is provided with the packing ring corresponding with valve 7, and pad is the nylon plain washer.Support top is with explosion-proof device cap 1.Be provided with spring 11 between plunger pressure cap and the support.Be provided with the inclined-plane nylon spacer 9 that is used to seal around the connecting rod of valve.The lower end of support is provided with the screw thread 13 that is connected with cranked tire valve.
Tyre explosion-proof equipment tightly is screwed on the valve of tire, and at this moment plunger pressure cap 12 is opened plunger, and tire pressure and explosion-proof device internal air pressure equate, regulate air pressure nut 4 again, and the side's of making pressure cap pressure is slightly larger than tire pressure.When treating that tire pressure raises, square pressure cap is opened, and discharges air pressure, tire pressure just often, square pressure cap is under the pressure of Regulation spring and be communicated with the valve closure, thereby plays high pressure gas, the closed effect in normal back, prevents the tire blast.
