Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a novel rotating positioning sleeve. Background Art

[0002] We install the faucet's water outlet pipe rotatably on the faucet body or install the pull-out water outlet joint on the water outlet pipe so that it can be detached and rotatably installed, so as to facilitate the rotation adjustment of the water outlet position of the water outlet pipe or the rotation adjustment of the water outlet joint. Whether it is a rotating water outlet pipe or a rotating water outlet joint, a rotating connector is required to complete the rotation action. The rotating connector includes a fixed end and a rotating end, wherein the fixed end is fixedly arranged on the water outlet pipe or the water outlet joint, and the rotating end is fixedly arranged on the faucet body or inserted on the water outlet pipe in a restricted rotation manner. The rotating connector is a plastic part, while the faucet body and the water outlet pipe are mostly metal parts. After being used for a period of time, the rotating end of the rotating connector will shake due to wear by the metal parts, lose the connection stability, and the replacement cost is high.

[0003] like Figure 1 and Figure 2 As shown. In order to protect the rotating connector, we set a new type of rotating positioning sleeve made of plastic material on the inner tube wall of the faucet or the water outlet. The new type of rotating positioning sleeve is used to limit the rotation of the rotating end of the rotating connector relative to the faucet or the water outlet, avoiding the direct contact and wear between the rotating connector and the faucet or the water outlet. A new type of rotating positioning sleeve mainly includes a sleeve body 1, an integrally arranged deformation strip 2, and an integrally arranged positioning protrusion 3. The sleeve body is fitted and installed on the inner wall of the tube body of the faucet or the water outlet, and a deformation gap 4 is formed between the side edge of the deformation strip and the sleeve body. The positioning protrusion is arranged on the deformation strip, and the tube body of the faucet or the water outlet is provided with a positioning hole 5 for the positioning protrusion to extend into to limit the movement of the sleeve body. During assembly, the positioning protrusion is pressed to deform the deformation strip inward, and the sleeve body is inserted into the inner wall of the tube body until the positioning protrusion passes through the positioning hole. The rotating end 6 of the rotating connector is fixed or detachably inserted into the sleeve body, and the rotation of the rotating end of the rotating connector relative to the sleeve body is limited by the rotation limiting structure on the sleeve body.

[0004] Although the above-mentioned new type of rotating positioning sleeve can well protect the rotating connector, it still has the problem of wear. Because the positioning protrusion is made of plastic material and the inner wall of the pipe body is thin, the positioning protrusion is cut by the wall of the positioning hole under the rotation of the rotating connector, and the positioning protrusion will gradually separate from the positioning hole and rotate with the rotating connector, causing the outlet pipe or outlet joint to lose connection stability.

[0005] This case was created to solve the problem that a new type of rotary positioning sleeve is not wear-resistant. Utility Model Content

[0006] Therefore, in view of the above problems, the utility model proposes a novel rotary positioning sleeve which has a reasonable structural design, is wear-resistant and can extend the service life.

[0007] In order to solve the above technical problems, the solution adopted by the utility model is: a new type of rotation positioning sleeve, including a sleeve body, the sleeve body is provided with a rotation limiting structure for limiting the rotation of the rotating end of the external rotating connecting member, the sleeve body is provided with a deformation opening, a metal deformation strip is provided in the deformation opening, the metal deformation strip is fixedly provided on the sleeve body at a position outside the deformation opening, and a metal positioning protrusion is fixedly provided on the metal deformation strip.

[0008] A further improvement is that the two free ends of the metal deformation strip are connected to each other to form an annular metal deformation strip.

[0009] A further improvement is that the metal deformation strips are folded outwards on both sides of the deformation opening to form angled portions that facilitate deformation.

[0010] A further improvement is that the corner portion is S-shaped.

[0011] A further improvement is that: an inclined surface is provided on the lower side of the metal positioning protrusion to facilitate sliding into the external positioning hole.

[0012] A further improvement is that an arc-shaped connecting surface is provided between the inclined surface and the end surface of the metal positioning protrusion to facilitate smooth entry into the external positioning hole.

[0013] A further improvement is that: a limiting protrusion is provided on the upper edge of the sleeve body for limiting the metal positioning protrusion from escaping downward from the external positioning hole.

[0014] A further improvement is that the metal deformation strip is integrally injection-molded on the sleeve at a portion outside the deformation opening.

[0015] A further improvement is that the metal deformation strip is bolted and fixed to the sleeve at a position outside the deformation opening.

[0016] A further improvement is that the metal deformation strip is glued to the sleeve at a position outside the deformation opening.

[0017] A further improvement is that the rotation limiting structure includes at least one plug hole opened downward along the upper end surface of the sleeve body and plugged into the plug block on the external rotating connector.

[0018] A further improvement is that the rotation limiting structure includes at least one slot longitudinally opened on the inner wall of the sleeve body and inserted into the plug block on the external rotating connecting member.

[0019] A further improvement is that: a material-saving groove is provided inwardly on the outer wall of the casing.

[0020] By adopting the above technical solution, the beneficial effects of the utility model are:

[0021] In this case, the sleeve body is still a plastic part to save costs. The deformation strip and the positioning protrusion are separated into metal parts, and the two free ends of the metal deformation strip are fixed on the sleeve body, which effectively solves the problem of wear of the positioning protrusion and extends the service life of the rotary positioning sleeve.

[0022] A further beneficial effect is that the two free ends of the metal deformation strip are connected to form an annular metal deformation strip, which increases the fixing area between the metal deformation strip and the sleeve, improves the connection strength, and strengthens the overall strength of the sleeve.

[0023] A further beneficial effect is that the S-shaped corner portions folded on both sides of the metal deformation strip in the deformation opening can reduce the deformation force driving the metal deformation strip to deform, making it easier for the metal positioning protrusion to be inserted into the external positioning hole.

[0024] A further beneficial effect is that the inclined surface provided along the lower side of the metal positioning protrusion facilitates the metal positioning protrusion to slide into the external positioning hole.

[0025] A further beneficial effect is that the arc-shaped connecting surface provided between the inclined surface and the end surface of the metal positioning protrusion facilitates the metal positioning protrusion to smoothly enter the external positioning hole.

[0026] A further beneficial effect is that the metal deformation strip and the sleeve body are integrally injection molded, thereby improving the overall strength and stability of the rotary positioning sleeve. BRIEF DESCRIPTION OF THE DRAWINGS
