Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of leakage proof detection device of welded nut, packet
Include steel plate 1 and inflate room 8, welded nut 2 is installed on steel plate 1, rubber stopper 3 is installed on welded nut 2, rubber stopper 3 it is upper
Side is equipped with observation cover 4, and the bottom of observation cover 4 is equipped with hose 5, and the other end of hose 5 is equipped with infusion port 6, the lower section of steel plate 1
With observation cover 4 corresponding positions inflator 7 is installed, inflate room 8 top be equipped with flapper 10, and inflate room 8 inside peace
Equipped with vent plug 11, through-hole 12 is offered on vent plug 11, flapper 10 is installed inside through-hole 12, and the lower section of vent plug 11 is equipped with
Inflating rod 13, inflate room 8 outer wall be equipped with anti-skid design 14.
In the present embodiment, observe that bubble, preferred rubber stopper 3 are equipped with and welding in order to facilitate what user was more clear
The corresponding screw thread of nut 2, rubber stopper 3, which is threadably secured, to be mounted on welded nut 2, and rubber stopper 3 is equipped with different models, is used
Family needs to select the rubber stopper 3 of corresponding model, blocks weldering using rubber stopper 3 when carrying out the welded nut 2 of detection different model
Connected nut 2 can be prevented from effectively emerging extra useless bubble by welded nut 2, user can be helped to be more clear
It observes, weld bubble as caused by welding airtightness deficiency is more practical.
It in the present embodiment, is more easily operated in order to facilitate user, it is preferred that the bottom of observation cover 4 is equipped with a circle rubber
Glue sucker, the top of inflator 7 also are provided with rubber suction cups, and observation cover is made of the acrylic board of transparent material, when in use, user
Can by its setting rubber suction cups will observation cover be adsorbed on steel plate 1, pinned always without using person it is not loose, using more
It is convenient and efficient.
In the present embodiment, in order to carry out 2 leakage proof detection device of welded nut to the welded nut 2 of different model
Detection, it is preferred that the bottom of compression chamber 9 with inflate the top of room 8 and be equipped with corresponding screw thread, compression chamber 9 with inflate room 8 and pass through spiral shell
Line is fitting to connection, and when the welded nut 2 to different model detects, the compression chamber 9 of different model may be selected, be applicable in model
It encloses wider.
