Abstract
The utility model relates to an airless spray gun. In the airless spray gun in the prior art, the rearward shift force-bearing site of a pull needle is held by two nuts or clamped by an open sleeve, and the pull needle is easy to break or slip out; the outer circle seal ring of the pull needle is a single rectangular seal ring, which is poorly reliable in sealing and easy for leakage; and the valve core of the spray gun has poor precision and interchangeability, so that the sprayer can not be conveniently used. In the utility model, a holding screw is arranged at the tail end of the pull needle of the spray gun to enable a top plate to be fixedly connected with the pull needle, so as to avoid the shortcomings that the pull needle is easy to break when the pull needle is held by two nuts and the pull needle is easy to slip out when the pull needle is clamped by an open sleeve; the sealing is more reliable, and the service life is longer; and the valve core and the valve base have better interchangeability, and the sealing is more reliable.
Description
Technical field
The utility model relates to the airless spraying field, relates in particular to a kind of airless spray gun.
Background technology
Airless spray gun of the prior art, drawing and moving stressed place behind the pin is that double nut and tight or opening sleeve clamp, and draws pin easy fracture, slippage; Drawing pin cylindrical sealing ring is single square RunddichtringO, and sealing reliability is low, easily leaks; Spray gun spool low precision, interchangeability is poor, and spray gun can easily not used.
Summary of the invention
Summary of the invention
The utility model is at above-mentioned deficiency, provides a kind of spray gun to draw pin not rupture and slippage, draws the more convenient rational airless spray gun of pin cylindrical sealing use more reliable, that the spool precision is higher.
What comprise spray gun draws pin, sealing ring, and rifle spool body draws the backshank end that holding screw is set at spray gun.
Drawing the slipper seal of pin cylindrical is sealing ring and one group of rectangular seal combination sealing of inner lining spring.
Rifle spool body front end is withheld a sintered carbide ball.
The utility model is drawing the backshank end that holding screw is set, and makes top board and draws pin to be connected and fixed, and has avoided two nuts and has strained at the pin easy fracture and opening sleeve clamps and to draw the eely defective of pin; Draw the slipper seal of pin cylindrical to be designed to inner lining spring energy storage sealing ring and one group of rectangular seal combination sealing mode, make sealing more reliable, longer service life; Withhold a sintered carbide ball at the spool front end, spool valve seat interchangeability is better, seals more reliable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is an airless spray gun example structure schematic diagram.
Fig. 2 is provided with the holding screw structural representation for drawing the backshank end.
Fig. 3 is an inner lining spring energy storage ring structure schematic diagram.
Fig. 4 is a rifle valve core structure schematic diagram.
The specific embodiment
See Fig. 1, airless spray gun under high pressure, cocking 11 promotes top board 8 to the right, overcome spring 10, draw pin to move right, rifle spool and valve seat 1 are opened, and coating flows to nozzle and sprays, when unclamping trigger 11, the rifle spool is moved to the left and closes spray gun under the effect of spring force.This airless spray gun holds out against and draws pin drawing pin 4 tail ends that holding screw 9 is set, and is connected in one with top board 8.Draw pin 4 cylindrical slipper seals to be designed to inner lining spring 5 energy storage sealing rings 6 and one group of rectangular seal 7 combined sealing structure.This airless spray gun is withheld a sintered carbide ball 2 at rifle spool body 3 front ends.
Claims (3)
1. one kind is used for the airless spray gun that field of coating is used, and what comprise spray gun draws pin (4), sealing ring (6), and rifle spool body (3) is characterized in that: draw pin (4) tail end that holding screw (9) is set at spray gun.
2. airless spray gun as claimed in claim 1 is characterized in that: drawing pin (4) cylindrical slipper seal is sealing ring (6) and one group of rectangular seal (7) combination sealing of inner lining spring (5).
3. airless spray gun as claimed in claim 1 is characterized in that: rifle spool body (3) front end is withheld a sintered carbide ball (2).
