Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, a water pipe and gun head connecting mechanism includes a gun head connecting pipe body 1 and a water pipe body 2, the water pipe body 2 is sleeved outside a port of the gun head connecting pipe body 1, the external thread of the gun head connecting pipe body 1 is connected with a fastening driving member 3, a connecting fastening member 4 is fixedly installed at an end portion of the gun head connecting pipe body 1, the fastening driving member 3 is used for driving the connecting fastening member 4 to be pressed, so that the connecting fastening member 4 presses the water pipe body 2, wherein the fastening driving member 3 includes a driving nut 31 and a pressing sleeve 32, the driving nut 31 is in threaded connection with the external portion of the gun head connecting pipe body 1, the pressing sleeve 32 is located at one side of the driving nut 31 and sleeved outside the gun head connecting pipe body 1, an inner wall of the pressing sleeve 32 is a conical surface, and the inner wall of the pressing sleeve gradually increases from the driving, Link board 42 and clamping ring 43, support 41 fixed connection is in the outer wall of rifle head connecting pipe body 1, the one end of linking board 42 articulates in the top of support 41, the other end fixedly connected with clamping ring 43 of linking board 42, the arch arc board on linking board 42, clamping ring 43 is the fan-shaped ring of the outer surface curvature of adaptation rifle head connecting pipe body 1, connecting fasteners 4 are equipped with four, and four connecting fasteners 4 annular array are in the outside of rifle head connecting pipe body 1, can make up into a complete ring when water pipe body 2 is hugged closely to four clamping rings 43.

During the use, earlier locate the tip of rifle head connecting pipe body 1 with water pipe body 2 cover, then twist drive nut 31 towards the direction of water pipe body 2 for drive nut 31 promotes to press tightly cover 32 to the direction removal of water pipe body 2, because the inner wall of pressing tightly cover 32 diminishes with the contact department internal diameter of link plate 42 gradually, can make link plate 42 receive bigger extrusion force gradually, thereby make the clamping ring 43 can sticis water pipe body 2, and then accomplish the fixed effect of cup jointing of water pipe body 2 and rifle head connecting pipe body 1. When the water pipe body 2 is disassembled, the driving nut 31 is reversely screwed, the pressing sleeve 32 is reversely pushed, the pressure of the pressing sleeve 32 on the connecting plate 42 is released, and the water pipe body 2 can be pulled out.

The driving nut 31 and the pressing sleeve 32 are arranged independently, and the pressing sleeve 32 and the connecting plate 42 are in friction extrusion, so that the driving nut 31 and the pressing sleeve 32 are arranged separately, and not only can the quick-wear component be replaced independently, but also the factory processing and production are facilitated.

Wherein, establish even board 42 into the arch, on the one hand, can stably receive the extrusion of tight cover 32 that compresses, and reduce area of contact, reduce tight cover 32 and carry out the resistance, reach laborsaving effect, on the other hand, go up the arch setting, can be under the state of dismantling water pipe body 2, when clamping ring 43 and the contact of the outer wall of rifle head connecting pipe body 1, the last arch face of even board 42 still can bulge the outer wall of rifle head connecting pipe body 1 to prevent tightly pressing the self-propelled of cover 32 and drop. In order to facilitate the replacement of parts, the bottom end of the support 41 and the outer wall of the gun head connecting tube body 1 can be in threaded connection, and when the pressing sleeve 32 needs to be replaced, the connecting fastener 4 is firstly screwed off and then replaced.

Wherein, establish spacing 5 at the inner wall that sticiss the cover 32, set up the draw-in groove in the surface correspondence of clamping ring 43, prevent to twist and move drive nut 31 and carry out tight pressure cover 32 when, drive tight pressure cover 32 and rotate in step, because of sticising cover 32 and even board 42 contact back, if take place the rotation of pressing the relative even board 42 of cover 32, its metal contact surface rotational friction can send comparatively harsh noise, above-mentioned setting, the production of effective noise reduction, facilitate the use.
