Abstract
The utility model belongs to spray guns, and particularly relates to a spray rate adjusting device of an air-pressure spray gun, which comprises a casing, a spray gun connecting seat, a switch triggerand a spray rate positioning and adjusting button. The utility model is characterized in that a position-limiting adjusting mechanism is screwed on the spray gun connecting seat, the position-limiting adjusting mechanism is in threaded fit connection with the spray rate positioning and adjusting button, a groove and a projected position-retaining rib are arranged on the casing, a spray rate positioning and adjusting button is axially fixed on the groove, and the position-limiting adjusting mechanism is inserted in the projected position-retaining rib of the casing. In the utility model, the spray rate positioning and adjusting button is rotated and the position-limiting adjusting mechanism is driven to move back and forth, and then the position-limiting stroke of the switch trigger can beadjusted, the opening degree of a valve needle and a nozzle bore inside the spray gun connecting seat can be adjusted, and the purpose of realizing the precise control on the spray rate is achieved.The spray gun is characterized by simple and reasonable structure, low cost, convenient adjustment, precise control and comfortable hand feeling.
Description
Technical field
The utility model belongs to the spray gun class, specifically is a kind of discharge rate adjusting device of blast spray gun.
Background technology
The discharge rate of existing blast spray gun is mainly regulated by trigger control, the little knob screw of employing, but regulate the stroke of trigger by little knob screw, sometimes adjusting knob can turn over head, sometimes to rotate several circles and locate directly perceived inadequately, structure is reliable inadequately again, and practical feel is not good enough, and discharge rate control is fine and smooth inadequately and accurate, thereby effect is undesirable in use, and operation is convenient inadequately.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of discharge rate adjusting device of blast spray gun rational in infrastructure, easy to operate, satisfactory for result is provided.
The technical solution of the utility model is as follows:
A kind of discharge rate adjusting device of blast spray gun, comprise housing, the spray gun Connection Block, the switch trigger, discharge rate location adjusting knob, it is characterized in that: be rotary with a limit adjusting mechanism on the spray gun Connection Block, limit adjusting mechanism is connected with discharge rate location adjusting knob threaded engagement, the gear muscle that one groove and a projection are arranged on the housing, groove axial restraint discharge rate location adjusting knob, make discharge rate location adjusting knob can not move forward and backward because of rotation produces, can only carry out the rotation of circumferencial direction, limit adjusting mechanism inserts on the gear muscle of housing projection, make limit adjusting mechanism can on circumference, not rotate, can only move forward and backward.
The utility model rotation discharge rate location adjusting knob drives limit adjusting mechanism and moves forward and backward, thereby the spacing stroke of by-pass cock trigger reaches needle in the adjustment spray gun Connection Block and the open degree between nozzle bore, realizes the purpose of meticulous control jet flow.The utlity model has simple for structure rationally, low, easy to adjust, the control of manufacture cost of parts accurately, the characteristics of comfortable feel.

Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model STRUCTURE DECOMPOSITION figure.
Fig. 3 is the utility model profile.
The specific embodiment
As shown in Figure 1, 2, the utility model is earlier at spray gun Connection Block 4 suit upper limit governor motions 3, and cover screws on discharge rate location adjusting knob 2 again, the composition body that has trigger is packed into fix in the housing 1 again.Limit adjusting mechanism 3 is that threaded engagement is connected with discharge rate location adjusting knob 2, when discharge rate location adjusting knob 2, when limit adjusting mechanism 3 and spray gun Connection Block 4 are packed housing 1 into, as Fig. 1, shown in Figure 3, fluted discharge rate location adjusting knob 2 is carried out axial restraint, make discharge rate location adjusting knob 2 can not move forward and backward because of rotation produces, can only carry out the rotation of circumferencial direction, when limit adjusting mechanism 3 is packed housing 1 into, limit adjusting mechanism 3 is inserted on the gear muscle 6 of rifle body upper process, make limit adjusting mechanism 3 can not rotate, can only move forward and backward at circumferencial direction.During operation, when adjusting knob 2 left-right rotation of discharge rate location, just drive limit adjusting mechanism 3 and move forward and backward, thus the spacing stroke of by-pass cock trigger 5, reach the open degree of 8 of the needle 7 adjusted in the spray gun Connection Block 4 and nozzle bores, realize the purpose of meticulous control discharge rate.
