Abstract

The present invention is related to a connector structure of a wall hanging type shower head, including a body, a connector, and a positioning nut positioning the connector on the body. A positioning ring is mounted between the rotation portion of the connector and the positioning nut. The positioning ring has an inner periphery provided with a limit edge rested on the rotation portion of the connector, and has an outer periphery formed with a positioning shoulder rested on the positioning nut. The positioning shoulder may be locked with the positioning nut to prevent the positioning nut from contacting the rotation portion of the connector directly, thereby preventing the rotation portion of the connector from being worn out, so as to increase the lifetime of the rotation portion of the connector.

Claims

1. A connector structure of a wall hanging type shower head, comprising a body having a threaded end for mounting a connector, a positioning nut screwed on the threaded end, the body having a seat portion for mounting a shower head, the body having a coupler joined with a water outlet pipe of the shower head, the connector having a first end formed with a rotation portion and a second end formed with a pipe connection portion, the positioning nut having a positioning edge for locking and positioning the rotation portion of the connector;

wherein,

a ring-shaped watertight washer is mounted between the rotation portion of the connector and the body; and

an elastic positioning ring that may be expanded and contracted elastically is mounted between the rotation portion of the connector and the positioning edge of the positioning nut, the positioning ring is formed with a retraction slit, the positioning ring is provided with an arcuate limit edge opposite to the rotation portion of the connector, and the positioning ring has an outer periphery formed with a positioning shoulder that is opposite to the positioning edge of the positioning nut.

2. The connector structure of a wall hanging type shower head in accordance with claim 1, wherein the limit edge of the positioning ring has a distal end formed with an enlarged edge.

3. The connector structure of a wall hanging type shower head in accordance with claim 1, further comprising a watertight pressurizing pad mounted in the pipe connection portion of the connector, and rested on a water inlet pipe, wherein, the watertight pressurizing pad is a hollow conic body having a surface formed with multiple contraction holes, so that when water is supplied from the water inlet pipe, the water may be collected and pressurized to flow through the multiple contraction holes to form multiple water beams in a slightly rotational manner, and the multiple water beams may flow through the water outlet pipe to enter the shower head for use.
