Water gun water supply adapter

The present invention relates to the field of adapters for controlling the direction of water discharge, and more particularly to a water supply adapter for a group of water guns.

According to the water spray gun system for gardening, it is connected with the water pipe, and a water supply adapter is arranged between the end of the water spray gun and the water pipe. In many patent cases in the country, the main structure of the water supply adapter mostly includes a water circulation pipe. An upper pivot joint, a lower pivot joint of the water flow tube, the upper and lower pivot joints respectively form a central joint end that can be pivotally connected to each other; wherein the joint end can be combined with the joint The holes are arranged in a sleeve design, and a waterproof ring is arranged therebetween, and a plug is locked by the tool to the sleeve joint end of the joint column and the joint hole, so that the upper and lower pivot joints can be pivoted. The two end edges of the upper and lower pivot joints are respectively joined by ultrasonic waves, and at the same time, the positioning of the positioning components is matched, so that the water supply adapter can be activated. The pivotal adjustment effect of the multi-stage water flow angle.

However, in general, the traditional water supply pivot joint structure, under the above structure, still has the following factors:

1. The pivoting base of the upper and lower pivot joints is required to cooperate with the binding column and The pivoting joint of the coupling hole cooperates, so that the central position of the water flow passage is usually occupied on the base, so that the range of the flow passage formed by the joint of the pivot joint is limited to the outer ring range of the opposite central outer side, and the water flow is formed under the phase. The difference between the inlet and outlet of the road varies greatly.

2. Since the upper and lower pivot joints are combined with the plug body, the base of the pivot joint is easy to form a water flow passage with more turning, so as to affect the smoothness of the water supply flow.

3. The joint ends of the upper and lower pivot joints are sleeved by the joint column and the joint hole, and then a combined plug body is sleeved and fixed by the tool, because the tool screw lock is required to be assembled. There is inconvenience in combination operation.

4. The upper and lower pivot joints are assembled by waterproof rings. Since the pivot joints are relatively pivoted to each other due to the spray angle requirement, the pivoting friction will squeeze and twist the soft ones. The waterproof ring causes the waterproof ring to deform and shorten the service life of the member.

In view of the above problems, the present creator further studies and develops. Therefore, the main purpose of the present invention is to provide a water supply adapter for a water gun, which can directly and quickly combine the adapter without tools, and can minimize The turning water runner design reduces the difference between the influent and the effluent.

In order to achieve the foregoing objectives, the technical means employed in the present invention is to provide a water supply adapter for a water gun, comprising: a first tube member including a first base, wherein the first base has a a chamber having a pin hole on one end surface; A connecting pin member is an elastic U-shaped frame body, and the free ends of the connecting pin members are configured as a clamping portion capable of allowing elastic expansion and condensation; and a first connecting tube is connected to the first portion An outer side of the first through pipe forms a laterally communicating water inlet passage for feeding the water supplier; a second pipe member is pivotally coupled with the first pipe member, and includes a second base The second base extends axially toward the first base end surface, and a middle column portion is recessed. The middle column portion is recessed with a middle flow passage communicating with the inlet and outlet water passages, and the middle column portion faces the first pipe member. The end of the line is provided with a plurality of flow ports and a buckle neck in the axial direction, wherein the flow port is penetrated through the side wall of the middle column portion and communicates with the middle flow channel, and the outer diameter of the buckle neck is small. The two clamping portions of the connecting pin member are fastened to the outside of the buckle neck through the pin hole, and the first and second pipe members are coupled to each other; and a second connecting pipe is connected to the second base. On the outside of the seat, the inner side of the second through pipe forms a water flow passage that laterally communicates with the flow port; by the water flow from the first through pipe The second water pipe is sent from the water flow channel through the water inlet channel, through the flow port, and the middle flow channel.
