The beneficial effects of the utility model are: compared with prior art, a kind of universal joint provided by the utility model
Structure is built in the first washer using bulb rotation and second packing ring is enclosed and set in space, and second packing ring is recessed inwardly to be formed
The rotation cavity configuration being rotatably assorted with bulb makes to realize universal rotational between swivel head and fixing sleeve, and then makes spray head and hose
Realize universal connection, structure is simple, production cost is low, and smooth degree is high, improves the service life of hose, user experience
It is good；And it is provided with sealing ring at rotation chamber and bulb cooperation, water shutoff performance is good, rotates more flexible.
Detailed description of the invention
Fig. 1 is a kind of structure chart of universal joints structure embodiment of the utility model.
Fig. 2 is the cross-sectional view of Fig. 1.
Fig. 3 is the explosive view of Fig. 1.
Specific embodiment
Shown in referring to figs. 1 to Fig. 3, a kind of universal joints structure in the utility model embodiment, including fixing sleeve 1, rotation
First 2 and external member 3；Fixing sleeve 1 is connected with spray head；Swivel head 2 includes bulb 21 and installing pipe 22, and bulb 21 is built in fixing sleeve
1, installing pipe 22 is connected with hose；External member 3 is set in fixing sleeve 1, and is set in the periphery of bulb 21；Specifically, external member 3
Including the first washer 31 and second packing ring 32, convenient for assembling to universal joint, the rotation of bulb 21 is built in the first washer 31
It is set in space with enclosing for second packing ring 32, installing pipe 22 is arranged in 31 center of the first washer, in order to which the rotation for improving bulb 21 is suitable
Slip, one end of second packing ring 32 towards the first washer 31 are recessed inwardly to form a rotation chamber 30, and rotation chamber 30 is matched with bulb 21
Sealing ring 301 is provided at conjunction, it is preferred that sealing ring 301 is O-ring, and the contact area of O-ring and bulb 21 is smaller, friction
Active force is small.The present embodiment makes to realize universal rotational between swivel head 2 and fixing sleeve 1, and then it is universal to realize spray head and hose
Connection, structure is simple, production cost is low, and smooth degree is high, and water shutoff performance is good, improves the service life of hose, user's body
It tests and feels.
In some embodiments of the utility model, universal joint further includes the pressing ring 4 for being built in fixing sleeve 1, pressing ring 4 with
32 upper end of second packing ring abuts, and keeps bulb 21 and the connection of external member 3 more stable, and bulb 21 will not occur axial direction and alter when rotation
