Anti-freezing garden water gun with adjustable lead screw

Abstract

The invention provides an anti-freezing garden water gun with an adjustable lead screw which is smart and reliable in conception. Four innovations can be progressed: firstly, a new convex-concave knurl (10b) is arranged on a rivet hole of a lock-up button (10) so as to prevent escaping and is provided with a groove (10a) so as to be convenient for moist fingers to grasp; secondly, the problem that a gun body is frost-cracked can be solved, the gun body is cracked caused by freezing because water is left in the gun body after the water is sealed in the water gun; the problem of sealing up at the far end can be solved thoroughly; after the hand is loosened, a pull rod is restored, a water stop of an equiangular spiral with equal pressure angles which is also called as a logarithmic spiral can be prevented from being locked and then can drive a far-end sealing seal ring to move forwards to seal water outside the gun; thirdly, a color plate (7) is provided with a plurality of triangular holes to be beneficial for various designs and colors; and fourthly, according to the adaptive screw pitch, lifting angle and lead, outer ring raised cards of a water inlet seal ring are adjusted, so the twisting inner stress is reduced, and the adaptive sealing is improved; furthermore, the problem that the anti-freezing effect is not thorough and is occasionally out of order because the rod of a far-end sealing plug can not be adjusted can be solved by adjusting the lead screw.

Description

technical field [0001] The invention relates to a water spray gun used for gardening, gardening and cleaning, in particular to an anti-freezing remote water-stop water gun and a threaded rod adjustment anti-freezing garden water spray gun, which belongs to the technical field of spraying devices. Background technique [0002] For gardening, water spray guns for gardening, and water spray guns for cleaning are widely used to spray water in the selected mode of people's preferences. At present, most of the water spray guns on the market have a handle and a spring top plug structure. The main working principle is: press the handle, and the water gun will discharge water; release the handle, and the top plug will reset and seal under the force of the spring. The water spray gun with such a structure brings certain inconvenience to use, that is, when the water gun needs to spray water for a continuous time, the user needs to press the handle all the time, so that the water gun ca...

Problems solved by technology

The water spray gun with such a structure brings certain inconvenience to use, that is, when the water gun needs to spray water for a continuous time, the user needs to press the handle all the time, so that the water gun can continuously discharge water, that is to say, the user needs to press the handle all the time. Only when the handle is held down, the water gun can continuously discharge water. A little longer time will make the user feel tired, especially for women.

For this reason, the water spray gun is provided with a locking button (10) with a rotating shaft, but it is troublesome to operate, that is to say, when holding the water spray gun handle with the right hand, it will be buckled with several fingers and nails of the left hand. The locking button is turned to a larger angle, and the locking button must be fastened to the inside of the upper edge of the handle; the locking button is close to the gun body, It is often difficult to grasp and slip with wet fingers, which is very troublesome to operate

There is also a more troublesome thing, that is, the problem of the gun body freezing and cracking; in the past, the water gun body was sealed near the rod plug, and there was water in the gun body. When it was not in use, it would freeze and cause the gun body to break; Overstrengthening the gun body, and adding plastic to put the sheath, but it does not work; how to prevent the gun body from freezing and cracking is easier said than done, and it is a long-standing unsolved problem in this field
