Description
Technical field
The utility model belongs to daily technical field, relates to a kind of linkage structure that is used for shower upper nozzle and outlet pipe.
Background technique
In existing shower, be connected by screw thread between the shower nozzle of shower and the outlet pipe.As shown in Figure 2, outlet pipe 7 is normally by being that interior pipe 72 and outer tube 71 are formed.In outlet pipe 7, interior pipe 72 is all-in-one-piece structures, and outer tube 71 is to be fastened mutually by several joint buttons to form.Pipe 72 the outside in outer tube 71 is socketed on is provided with one and is used for the pipe thread 1 that is connected with shower nozzle 5 in the end of outer tube 71.When outlet pipe 7 with after shower nozzle 5 is connected, the connecting end of interior pipe 72 has an inner core 3 that is connected with interior pipe 72, this inner core 3 is pressed between shower nozzle 5 and the pipe thread 1.Therefore, interior pipe 72 is fixed together with shower nozzle 5.
Because shower in use, along with repeatedly or the adjustment in many people's the taking and placing and the orientation of having a bath, make the shower nozzle can irregular rotation.In this structure of existing shower, because of interior pipe and shower nozzle are the relations that is fixed together, interior pipe can follow shower nozzle to rotate together.Though the outside of pipe can not rotated in outer tube sleeve was connected to, interior pipe can produce distortion because of rotating, and causes not even water outlet of the improper water outlet of outlet pipe, has directly influenced the working life of shower.
In addition, along with the continuous rotation distortion of shower nozzle, the sealing of shower nozzle and outlet pipe joint also is affected, and leakage phenomenon may occur.
Summary of the invention
The purpose of this utility model is at the problems referred to above, the linkage structure of a kind of shower fitting spray nozzle and outlet pipe is provided, the interior Guan Buhui of outlet pipe is rotated along with shower nozzle, thereby the phenomenon that has prevented the improper water outlet of outlet pipe takes place, improve the sealing of joint, prolonged the working life of shower.
The purpose of this utility model can realize by following technical proposal: the linkage structure of this shower fitting spray nozzle and outlet pipe is arranged between shower fitting spray nozzle and the outlet pipe, outer tube in outlet pipe is socketed on by pipe in one and one outside the pipe is formed, the connecting end of the interior pipe inner core that is being connected, the outer side surface of inner core is provided with convex shoulder, a pipe thread is socketed on the connecting end of outer tube, pipe thread is connected with shower nozzle by screw thread, it is characterized in that, be provided with the back-up ring of a ring in the described pipe thread, back-up ring is fixed in the pipe thread by screw thread, the internal diameter of back-up ring is greater than the external diameter of inner core, between pipe thread and inner core, leave the gap, and between inner core and pipe thread, be provided with seal washer.
In the utility model, pipe thread is connected by screw thread with shower nozzle.Because leave the gap between pipe thread and the inner core, inner core can not rotate along with the rotation of pipe thread.The convex shoulder of inner core outer side surface plays and prevents that inner core breaks away from the effect of pipe thread.Simultaneously, the seal washer between inner core and the pipe thread makes between pipe thread and the inner core to keep sealing.
In the linkage structure of above-mentioned shower fitting spray nozzle and outlet pipe, also be provided with seal ring between described back-up ring and the pipe thread.This seal ring is used for the sealing between back-up ring and the pipe thread.
In the linkage structure of above-mentioned shower fitting spray nozzle and outlet pipe, the connecting end of described interior pipe is socketed on the inner core.Usually, interior pipe is socketed on the inner core by drive fit.By such mode, pipe is fixed together with inner core in making.
In the linkage structure of above-mentioned shower fitting spray nozzle and outlet pipe, the cross section of described seal washer is V-shaped, and its opening direction is towards this side of back-up ring.Adopt this packing ring, make in actual use, the edge of V-arrangement packing ring can open, and improves the sealability at inner core place.
In the linkage structure of above-mentioned shower fitting spray nozzle and outlet pipe, sometimes the outer tube of outlet pipe by several joints buckle mutually fasten form.This structure makes outer tube more flexible, can not rotate along with the rotation of shower nozzle.
Compared with prior art, the utility model is by adopting novel structure, and Guan Buhui rotates along with the rotation of shower nozzle in making, and has guaranteed the normal use of outlet pipe, can prolong the working life of shower.Simultaneously, owing to used Sealings such as seal washer and seal ring, make linkage structure that good sealing property be arranged, so have higher utility.

Among the figure, 1, pipe thread; 11, retaining edge; 2, back-up ring; 3, inner core; 31, convex shoulder; 4, seal ring; 5, shower nozzle; 6, seal washer; 7, outlet pipe; 71, outer tube; 711, joint button; 72, interior pipe; 8, sealing gasket.
Embodiment
As shown in Figure 1, this shower fitting spray nozzle comprises parts such as shower nozzle 5, outlet pipe 7, inner core 3, back-up ring 2 and seal washer 6 with the linkage structure of outlet pipe.The structure of shower nozzle 5 and outlet pipe 7 is identical with common shower structure.Outlet pipe 7 is made up of interior pipe 72 and outer tube 71.In the present embodiment, interior pipe 72 is an integral structure, and outer tube 71 is to be snapped together the outside of pipe 72 in being socketed on mutually by several joint buttons 711.This structure of outer tube 71 not only helps any bending of pipe, and can rotate arbitrarily and do not influence the soundness of its connection.
As shown in Figure 1, in the present embodiment, the connecting end of interior pipe 72 is socketed on the inner core 3 by drive fit, so inner core 3 is fixed together with interior pipe 72.Inner core 3 is loaded in the pipe thread 1, and the outer side surface of inner core 3 has a convex shoulder 31, makes inner core 3 can not break away from pipe thread 1.Also being equivalent to pipe thread 1 is in the connecting end of outlet pipe 7 and can not detaches water pipe 7.Obviously, after making pipe thread 1 and shower nozzle 5 is connected by screw thread, shower nozzle 5 just is connected with outlet pipe 7.
The inner side surface of pipe thread 1 has internal thread.The back-up ring 2 of ring and pipe thread 1 are connected by screw thread.As shown in Figure 1, in the present embodiment, a retaining is arranged on the madial wall of pipe thread 1 along 11.After back-up ring 2 is screwed into pipe thread 1, is kept off along 11 and being blocked.Like this, guarantee to leave the gap between back-up ring 2 and the inner core 3, inner core 3 can and not rotated along with back-up ring 2 rotations.But back-up ring 2 can be along with shower nozzle 5 rotates together.
The internal diameter of back-up ring 2 is greater than the external diameter of inner core 3, inner core 3 is being kept off by back-up ring 2 all the time and can not pass back-up ring 2.
In the present embodiment, being provided with the seal washer 6 of V-arrangement between inner core 3 and the pipe thread 1, being provided with O shape rubber seal 4 between back-up ring 2 and the pipe thread 1, all is to keep sealing for this linkage structure.
When reality is used, normally also establish a sealing gasket 8 between the back-up ring 2 in shower nozzle 5 and pipe thread 1, play the seal action between shower nozzle 5 and the pipe thread 1.
