Description

TECHNICAL FIELD

[0001] The utility model relates to the bathroom technical field, concretely relates to adjustable telescopic elbow joint. BACKGROUND

[0002] The elbow joint is mainly used for the installation of the faucet and the shower head. During the installation, two reserved pipes are usually pre-buried on the wall, and then the water inlet pipes of the two elbow joints are respectively positioned on the water outlets of the two reserved pipes, and then the elbow joint body is rotated to tighten and lock the water inlet pipes and the reserved pipes, so that the water outlet height and distance of the two water outlets are adjusted through the elbow joint body, which facilitates the installation of the shower body and the reserved pipes.

[0003] However, the depth of the reserved pipe joint in the wall from the wall surface may deviate from the predetermined depth, and the too short water inlet pipe may also cause the elbow joint body to be too close to the wall, so that the elbow joint body is inevitably collided with the wall if the elbow joint body is continuously rotated to tighten and lock the water inlet pipe and the reserved pipe, which may cause the wall surface and the elbow joint body to be worn out, which is extremely inconvenient to use. The too long water inlet pipe may cause the shower body to be unable to be installed close to the wall.

[0004] Therefore, the present application is produced in view of the above-mentioned defects in the prior art. CONTENT OF THE UTILITY MODEL

[0007] An adjustable telescopic elbow joint, comprising a threaded joint, a locking screw and an integrally formed pipe joint body, wherein the pipe joint body has a sliding sleeve segment for sleeving the threaded joint, the pipe joint body further comprises a plug-in segment for connecting with a shower faucet, the sliding sleeve segment and the plug-in segment are in communication with each other, and the sliding sleeve segment and the plug-in segment are arranged in parallel but not in line.

[0008] An outer thread is formed on the outer wall of the threaded joint, a screw through hole is further formed on the outer wall of the threaded joint, and the locking screw is installed in the screw through hole; a first sealing ring is sleeved on the outer wall of the sliding sleeve segment near the pipe opening, a limiting groove extending in the axial direction is further formed on the outer wall of the sliding sleeve segment; the threaded joint is slidingly sleeved on the sliding sleeve segment, the first sealing ring is sealingly abutted with the inner wall of the threaded joint, and the locking screw is abutted in the limiting groove.

[0009] Further, two screw through holes are formed on the threaded joint, and one locking screw is arranged in each screw through hole.

[0010] Further, the abutting part of the locking screw is conical, and the cross section of the limiting slot is triangular.

[0011] Further, a clearance step hole is formed on the end of the threaded joint towards the plug-in part.

[0012] Further, the tail part of the locking screw has an internal hexagonal counterbore.

[0013] Further, two first installation slots are formed on the outer wall of the sliding sleeve joint part, and one first sealing ring is arranged in each first installation slot.

[0014] Further, a second installation slot is formed on the outer wall of the plug-in part, and a second sealing ring is arranged in the second installation slot.

[0018] Further, a check valve allowing water to flow only from the sliding sleeve joint part to the plug-in part is arranged in the plug-in part, and a limiting snap spring is arranged between the check valve and the outlet of the plug-in part.

[0019] After the above structure is adopted, the adjustable telescopic elbow joint has at least the following beneficial effects:

[0020] I. The threaded joint can slide with the sliding sleeve joint part to adjust the distance between the plug-in part and the threaded joint, so that the actual situation of the reserved water supply joint in the wall can be adjusted conveniently. The first sealing ring seals with the inner wall of the threaded joint, so that water leakage is prevented. The screw cooperates with the limiting slot, so that the sliding sleeve joint part and the threaded joint can be fixed axially relative to each other after the locking screw is locked, and the axial rotation of the threaded joint relative to the sliding sleeve joint part is limited.

[0021] II. By arranging the locking screw, the threaded joint is limited from both sides, so that the threaded joint and the sliding sleeve joint part are more firm after being locked.

[0022] III. After the locking screw is locked, the pipe joint body can be rotated by a wrench to make the threaded joint threadedly connected with the water supply joint reserved in the wall. Specifically, the wrench can drive the clamping position on the outer wall of the connecting section, or a hexagonal wrench drives the internal hexagonal wrench position inserted into the pipe opening of the inserted section.

[0023] IV. The check valve plays a role of placing water flow backflow, and avoids the water flow in the shower faucet backflowing to the water supply joint reserved in the wall.

[0024] Compared with the prior art, the threaded joint and the sliding sleeve connecting section are connected in the improved manner, so that the shower faucet can be installed close to the wall according to the actual situation of the water supply joint reserved in the wall.
