Abstract
The utility model relates to a gas tightness inspection jig, it includes inside lining axis of cone main part, compress tightly the taper sleeve and the jack panel, it in inside lining axis of cone main part, compresses tightly the bell mouth of taper sleeve and the male cone (strobilus masculinus) of inside lining axis of cone main part and matches to compress tightly the taper sleeve cover to the jack panel passes through threaded connection to be installed in inside lining axis of cone main part, will compress tightly the taper sleeve and compress tightly on the male cone (strobilus masculinus) of inside lining axis of cone main part. The utility model discloses actively the effect lies in: the utility model discloses sealed inspection jig be through and the coarse pitch screw of jack panel is rotatory promotes to compress tightly the taper sleeve and will work the male cone (strobilus masculinus) of clothing collarband department and inside lining axis of cone main part under water and form the face seal to make the clothing collarband department of working obtain reliable sealed and locking under water, the security is high, difficult gas leakage.
Description
Technical field
The utility model belongs to mechanical frock clamp art, is specifically related to air tight test fixture, carries out the fixture of air tight test in water especially for underwater operation clothes.
Background technology
Whole clothes, normally the neckline place shutoff of underwater operation clothes, are then put into water by the air tight test of underwater operation clothes, utilize neckline place fairlead injecting compressed air to realize detecting.Existing underwater operation clothes neckline place generally adopts the wooden impermeability inspection jig of internal expansion type into and out of tracheae shutoff, its structure is right cylinder, a ring groove is had in the middle part of the external diameter of axial direction, during detection, fixture is filled in underwater operation clothes neckline place, utilize cylindrical external diameter to be produced by underwater operation garment collar port part and compress also externally rising, then with rope, underwater operation clothes neckline edge is bundled in the ring groove in the middle part of fixture, to reach the effect of sealing.The fixture of this structure has following shortcoming in use:
1, the rope of binding between neckline and fixture, often leak gas by compression bad causing, and then impact is to the bubble-tight judgement of underwater operation clothes, reduces product quality.
2, owing to will be filled with gases at high pressure by operation inner under water, when friction force between fixture and underwater operation clothes is not enough, fixture easily comes off or collapses, gently then destroy product, heavy then injure the person, there is severe compromise.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of air tight test fixture, its security is good, not easily leaks gas.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of air tight test fixture, and it comprises liner axis of cone main body, compresses tapered sleeve and fastening screw nut; Compressing tapered sleeve is enclosed within liner axis of cone main body, and the compression bellmouth of tapered sleeve and the male cone (strobilus masculinus) of liner axis of cone main body match, and fastening screw nut is threaded connection and is arranged in liner axis of cone main body, is pressed on the male cone (strobilus masculinus) of liner axis of cone main body by compression tapered sleeve.
In such scheme, in described liner axis of cone main body, be provided with air intake opening and gas outlet.
Part material of the present utility model generally adopts plastics, it axially adopts the mode be threaded, utilize the screw thread of fastening screw nut and liner axis of cone main body change both relative position can promote to compress tapered sleeve and adjust the deflection of underwater operation clothes neckline material to reach better locking effect, decrease the possibility coming off and judge by accident, improve the impermeability quality of underwater operation clothes.
The course of work:
Carry out underwater operation clothes air tight test, need at neckline location application the utility model.The neckline place of underwater operation clothes is nested in liner axis of cone main body of the present utility model, then install and compress tapered sleeve, with the taper hole face compressing tapered sleeve, underwater operation clothes neckline material is pressed on the male cone (strobilus masculinus) of liner axis of cone main body, by being threaded into fastening screw nut, promoting to compress tapered sleeve is locked in liner axis of cone main body by underwater operation clothes neckline place, finally by the draft tube on air tightness detection equipment, escape pipe insert respectively in the corresponding air intake opening of liner axis of cone main body of the present utility model and gas outlet, underwater business clothing is put in water, open air tightness detection equipment to inflate, the visual impermeability quality whether having gas leakage to judge underwater operation clothes.
The utility model good effect is: the utility model inspection of hermetic seal fixture compresses tapered sleeve by the steep-pitch thread rotation forces of fastening screw nut the male cone (strobilus masculinus) forming surface of underwater operation clothes neckline place and liner axis of cone main body to be sealed, thus make underwater operation clothes neckline place be sealed reliably and lock, easy to operate, structure is simple, and locking effect is good, difficult drop-off, eliminate the potential safety hazard in work, security is high, can not damage product, and detection efficiency is improved; The plastic material adopted is lightweight, decreases the labour intensity of testing staff.
