Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

The first embodiment is as follows:

a multi-seal spray gun can be seen by combining fig. 1, fig. 2, fig. 3 and fig. 4, and comprises a valve body 1, a handle 2 and a nozzle 3, wherein a water inlet 11 below the valve body 1 is in threaded connection with the handle 2. The water outlet 12 of the valve body 1 is connected with the nozzle 3 in a threaded manner. A valve core 4 is arranged at the position of a water outlet 12 in the valve body 1, and a movable rod 5 is assembled at the rear end of the valve core 4 through threads. A horizontal channel 13 for the movable rod 5 to move back and forth is arranged in the valve body 1, and the outer side of the channel 13 is sleeved by the spring 8. The lateral wall of movable rod 5 is provided with a plurality of annular grooves 51, a plurality of cup joints on annular groove 51 and contradict at the sealing washer 6 of passageway 13 inner wall, and the rear end of movable rod 5 rotates through the bolt and connects clamp plate 7, is provided with supporting part 71 on the clamp plate 7, and supporting part 71 supports and leans on the valve body 1 outer wall, is provided with spring 8 between the inner chamber of case 4 and valve body 1, and spring 8 makes case 4 support and leans on the rear end at nozzle 3. The center of the front end of the valve core 4 is provided with a tool hole 41, and the fixed position of the valve core 4 and the movable rod 5 can be adjusted by rotating the valve core 4 through the tool hole 41. The rear end of the valve body 1 is provided with a limiting sleeve 14, the upper end of the pressure plate 7 is embedded into the limiting sleeve 14, and the limiting sleeve 14 limits circumferential rotation of the pressure plate 7.

Based on the structure, the assembly mode of the scheme is as follows: firstly, a valve core 4 is placed at the position of a water outlet 12 of a valve body 1, a movable rod 5 which is assembled with a pressure plate 7 is placed at the rear end of the valve body 1, a spring 8 is sleeved between the valve core 4 and the movable rod 5, the valve core 4 is fixed on the movable rod 5 through the rotation of the valve core 4, one end of the spring 8 is pressed in the valve body 1 at the moment, and finally, a nozzle 3 is assembled. And, because the lateral wall at movable rod 5 has a plurality of sealing washer 6 and contradicts with the inner wall to sealing performance is reliable, lasting, in using, utilizes leverage principle to press clamp plate 7, can be more laborsaving, and it is also very convenient to change the sealing washer 6 here.

When the nozzle 3 is dismounted, the tool hole 41 in the valve core 4 can be used for rotating tools such as a hexagonal tool or other screwdrivers, so that the nozzle can be dismounted and assembled conveniently, and meanwhile, the fixed position can be adjusted, and the nozzle 3 is more adaptive to different nozzles.

Meanwhile, the limiting sleeve 14 is used for preventing the movable rod 5 or the pressure plate 7 from rotating along with the rotation when the valve core 4 is rotated, so that the assembly efficiency is greatly improved;

example two:

according to the first embodiment, referring to fig. 5, the opening of the channel 13 at the rear end of the valve body 1 is provided with a tapered opening structure 15, and the opening structure 15 is provided with the second sealing member 9 fitting the shape of the opening. The second seal 9 is provided with a skirt 91, and the skirt 91 is located below the abutting surface of the pressure plate 7 and abutted by the pressure plate 7. The support portion 71 of the pressure plate 7 is supported on the skirt 91. The second seal 9 is also made of rubber.

It can be seen that the second sealing element 9 is further provided, so that the sealing reliability is greatly improved, the second sealing performance has the effect of preventing leakage of the outside, the abrasion of the second sealing ring 6 is reduced, and the durability is improved. Since the supporting portion 71 of the pressure plate 7 also abuts against the second sealing member 9, the second sealing member 9 not only has a sealing effect, but also serves to block the pressure plate 7 and the valve body 1, thereby reducing friction between the pressure plate 7 and the valve body 1.

Of course, the above is only the typical example of the present invention, in addition, the present invention can also have other multiple specific embodiments, and all the technical solutions formed by adopting equivalent replacement or equivalent transformation all fall within the scope of the present invention.
