Abstract
The utility model discloses a novel paint spray gun, comprising a spray gun main body, and a paint tank in threaded connection with the spray gun main body, wherein the main spray gun body is provided with an internal thread, the paint tank is provided with an external thread matched with the internal thread, the external thread and the external thread are ladder-shaped and form a 30-degree engaging angle. According to the utility model, the spray gun main body and the paint tank are connected by ladder-shaped threads, and as the thread pitch of the ladder-shaped threads is long, the number of turns of the ladder-shaped thread is less than that of a fine thread as long as the ladder-shaped thread, therefore, the cleaning is convenient, the consumed time is short and the working efficiency is improved favorably; and the paint tank can be screwed down and on by few turns, so that the possibility that the contact surfaces of the paint tank and the main spray gun body are damaged by friction is greatly reduced, and the paint spray gun has high reliability and long service life.
Description
Technical field
The utility model relates to a kind of spraying equipment, relates in particular to a kind of new coating spray gun.
Background technology
Blackwash sprayer is a kind of application spraying equipment extremely widely, is formed by spraygun body and paint can two big component-assembled as the one of which, at present known blackwash sprayer; All be to link together between spraygun body and the paint can through fine thread according to the DIN103 standard design; The nominal diameter of fine thread is between M16 and M22, and pitch is 1.0mm or 1.5mm, utilizes this fine thread; Paint can effectively be connected with spraygun body, thereby has guaranteed the operate as normal of blackwash sprayer.Yet existing this blackwash sprayer finds that in actual use it also has the significant deficiency that can not be ignored: after the use, the cleaning of fine thread is very time-consuming; At least need change 10 circles could screw on paint can or back out, and be rigidity contact seal between paint can and the spraygun body, and the rotation number of turns is too much; The damage of contact-making surface appears because of friction easily; Cause the blackwash sprayer can't operate as normal, thereby reliability is lower, service life be short.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of new coating spray gun, and it is easy to clean not time-consuming, and reliability is high, long service life.
For realizing that above-mentioned purpose the utility model adopts following technical scheme:
A kind of new coating spray gun; Comprise spraygun body, the paint can that is threaded with spraygun body, this spraygun body is provided with internal thread, and paint can is provided with the external screw thread suitable with internal thread; Said external screw thread, internal thread are trapezoidal thread, and both angles of engagement are 30 °.
As a kind of preferred version, said external screw thread is 1/2 circle.
As a kind of preferred version, said internal thread is 1/4 circle.
As a kind of preferred version, the diameter of said external screw thread, internal thread is between 16-22mm.
As a kind of preferred version, the pitch of said external screw thread, internal thread is between 2-3mm.
A kind of new coating spray gun that the utility model is set forth, its beneficial effect is: this product connects spraygun body and paint can through trapezoidal thread, because the pitch of trapezoidal thread is bigger; Thread turns on the same length is less than fine thread; Therefore not only cleaning is very convenient, and weak point consuming time helps increasing work efficiency; And only need change the less number of turns and can paint can screwed on or backs out; Greatly reduce the impaired possibility of contact-making surface friction between paint can and the spraygun body, reliability is high, long service life.
Description of drawings
Fig. 1 is the configuration diagram of the utility model embodiment.
The specific embodiment
Come the utility model is further described below in conjunction with accompanying drawing and specific embodiment.
Please with reference to shown in Figure 1, it has demonstrated the concrete structure of the utility model preferred embodiment, and a kind of new coating spray gun comprises spraygun body 10 and paint can 20, wherein:
Said spraygun body 10 is provided with internal thread, and internal thread is the trapezoidal thread of 1/4 circle, and diameter is between 16-22mm, and pitch generally is 3mm, and pitch is as long as then all be fine between 2-3mm certainly.
Said paint can 20 is threaded with spraygun body 10; This paint can 20 is provided with and the suitable external screw thread of the internal thread of spraygun body 10; Can easily paint can 20 be screwed on or back out by this; This external screw thread is the trapezoidal thread of 1/2 circle, and its diameter, pitch are identical with internal thread, and both angles of engagement are 30 °.Be pointed out that for strengthening the sealing of paint can 20 and spraygun body 10, on said spraygun body 10, be provided with seal washer, strengthening sealing with seal washer is conventional means well known in the art, is not described in detail in this.
This product connects spraygun body 10 and paint can 20 through trapezoidal thread, because the pitch of trapezoidal thread is bigger, the thread turns on the same length is less than fine thread; Therefore not only cleaning is very convenient, and weak point consuming time helps increasing work efficiency; And only need change the less number of turns and can paint can 20 screwed on or backs out; Greatly reduce the impaired possibility of contact-making surface friction between paint can 20 and the spraygun body 10, reliability is high, long service life.
The above; It only is the utility model preferred embodiment; Be not that the technical scope of the utility model is done any restriction; So every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any trickle modification, equivalent variations and modification that above embodiment did.
