Description
Technical Field
The utility model belongs to the technical field of spray gun, in particular to seal structure of spray gun.
Background
The structure of a paint spray gun mainly comprises a gun body, an outer nozzle and an inner nozzle, and the assembly relationship among the gun body, the outer nozzle and the inner nozzle is generally as follows: the outer nozzle is in threaded connection with the outer side wall of the front end of the gun body through a fixing ring, and the inner nozzle is bonded at the axle center of the front end of the gun body through sealing glue. The structure has the disadvantages that the inner nozzle can not be detached from the gun body; the sealant can age when used for a long time, resulting in the loss of the sealing function.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a seal structure of spray gun, it is convenient to dismantle, and sealing performance is good, long service life.
The purpose of the utility model is realized like this: the utility model provides a seal structure of paint gun, includes the rifle body, outer nozzle and interior nozzle, outer nozzle is through solid fixed ring spiro union on the lateral wall of rifle body front end, the front end of the rifle body is coaxial to be provided with the go-between, is provided with the internal thread in the go-between, interior nozzle spiro union is in the go-between, be provided with the annular seal spare of flexible material preparation between interior nozzle and the go-between, radially be provided with three seal lips on the seal spare, be the first seal lip of setting terminal surface in the front, the second seal lip at middle part and the third seal lip of rear end face respectively, the annular groove joint of first seal lip and interior nozzle inner wall, the second seal lip is connected with the rear end face contact of interior nozzle, and the third seal lip is connected with the preceding terminal surface contact of go-between.
The front end surface of the first sealing lip is provided with a conical guide head.
The radial dimension of the second sealing lip is the same as that of the third sealing lip, and the radial dimension of the first sealing lip is half of that of the second sealing lip and that of the third sealing lip.
The flexible material is selected from rubber, silica gel or plastic.
The flexible material is preferably plastic.
Compared with the prior art, the utility model outstanding and profitable technological effect is:
1. the utility model discloses change the mode that the sealed glue that glues bonds of tradition to shower nozzle in threaded connection's mode installation to reach the technological effect of easy dismantlement, set up the sealing member simultaneously between the go-between of the rifle body and interior shower nozzle, reach sealed effect.
2. The utility model discloses a sealing member of unique structure, through first seal lip with the firm installation of sealing member on interior shower nozzle, second seal lip and third seal lip are extruded to the in-process of interior shower nozzle spiro union go-between, second seal lip and third seal lip expansion deformation for seal lip and each contact surface complex are inseparabler, in order to reach better sealed effect.
