Specific embodiment

The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model Limitation.

As shown in Figure 1, present embodiment water transfer rinsing machine water gun structure, including fountain head 2 and with fountain head 2 The water inlet pipe 1 of connection, the surface of water inlet pipe 1 are fixedly connected with water tubular union 3, and 2 periphery of fountain head is fixedly connected with spray head company Fitting 8 is provided with elastic positioning pin 4 on water tubular union 3, and elastic positioning pin 4 is along the radial direction point for being parallel to water inlet pipe 1 Cloth, and water tubular union 3 and spray head connector 8 are locked along the radial direction of water inlet pipe 1.The left end of fountain head 2 is additionally provided with water pipe Connector 9, is arranged internal screw thread in the inner sidewall of water inlet pipe 1, and corresponding external screw thread, rotation is arranged in the periphery of water pipe joint 9 Fountain head 2 can then lock the mode that fountain head 2 and water inlet pipe 1 are connected through a screw thread.In addition, the setting of elastic positioning pin 4 can To assist the locking of fountain head 2 and water inlet pipe 1, fall off after avoiding 2 long-time use of fountain head.

Specifically, elastic positioning pin include widow bolts 42, widow bolts 42 close fountain head 2 one end buckle structure 41, be fixedly connected on one end of the separate fountain head 2 of widow bolts 42 supports only plate 43, supports only between plate 43 and water tubular union 3 It is provided with compressed spring 5.Widow bolts 42 and buckle structure 41 are an overall processing part, be can be and widow bolts 42 to only plate 43 Weld together, buckle structure 41 is the small vertebral body structure of the big right end in left end of diagram, and vertebral body structure is filled with spray head connector 8 Timing, 42 right end of widow bolts carry out Light deformation, corresponding second annular spacing groove 81 can be arranged in spray head connector 8, then vertebra Body structure can be caught in the second annular spacing groove 81, the separate fountain head 2 that water tubular union 3 is arranged, so that water inlet pipe 1 and spray After head 2 connects, there are certain spacing between water tubular union 3 and spray head connector 8, so that widow bolts 42 be made to expose water The part of pipe connections 3 can be deformed in assembly.

As shown in figure 3, water tubular union 3 be a torus, be arranged on it is multiple conducive to widow bolts 42 pass through insert Hole, then widow bolts 42 are inserted into water tubular union 3 and are slidably matched with water tubular union 3.Compressed spring 5 is pressed, until buckle Structure 41 is caught in the second annular spacing groove 81, then completes locking operation.When buckle structure 41 is caught in the second annular spacing groove 81 When middle, measurement is good to support the only spacing between plate 43 and water tubular union 3, and selecting here is maximum spring away from interior decrement, In this way, the coupling mechanism force when fountain head 2 and water inlet pipe 1 are locked is maximum, effect is best.

Here, as shown in Figure 1, setting assembly inclined-plane 82 on side can also be assembled in the upper end of spray head connector 8, so that Buckle structure 41 can carry out assembly guiding by assembling inclined-plane 82, be conducive to assemble.

It is worth noting that the number of elastic positioning pin 4 can for two, three or more, it is not limited to diagram Two, the number of elastic positioning pin 4 is more, and coupling mechanism force is better, and elastic positioning pin 4 distribution need to around water inlet pipe 1 circumference it is equal Even distribution, coupling mechanism force radial in this way is more evenly.

In some embodiments, one end that water pipe joint 9 is close to fountain head 2 is arranged with sealing rubber ring 7, sealing rubber ring One end of 7 close water inlet pipe 1 is provided with flange collar 71, as shown in Fig. 2, annular spacing groove 12 is provided at the nozzle of water inlet pipe 1, Flange collar 71 and annular spacing groove 12 are interference fitted.Flange collar 71 is used for entire sealant after water pipe joint 9 protrudes into water inlet pipe 1 Circle 7 is positioned, and 71 inserting end of flange collar can be also made into the ascending gradual change diameter of diagram, facilitate the assembly of density cushion rubber 7, Flange collar 71 is interference fitted with 1 inner wall of water inlet pipe so that good airproof performance is water-tight.

In some embodiments, water tubular union 3 is to be passed through bolt by the first half rings 31 and the second half rings 32 and connected It connects the entire circular part of to be formed one, is provided with several insertion water inlets on the first half rings 31 and the second half 32 inner sidewalls of ring Position limiting structure 6 on 1 lateral wall of pipe, position limiting structure 6 can be several convex closures, and in the corresponding limit of periphery setting of water inlet pipe 1 Position slot 11, so that convex closure just can be inserted in limiting slot 11, it will not be mobile towards the radial direction of water inlet pipe 1.Water tubular union 3 This connection type it is simple, only several shallow grooves need to be set on the surface of water inlet pipe 1.

Although oneself is through the embodiments of the present invention have shown and described, it will be understood by those skilled in the art that: These embodiments can be carried out with a variety of variations, modification, replacement in the case where not departing from the principles of the present invention and objective And modification, the scope of the utility model are defined by the claims and their equivalents.
