Description

Angle-adjustable bent joint type loose joint for water supply

Technical Field

The utility model relates to a tubular product field, concretely relates to angle-adjustable angle knee joint formula is loose joint for feedwater.

Background

The bent movable joint is used for connecting a pipe body at a corner, the conventional bent movable joint is generally 90 degrees, however, the corner or a pipeline to be connected is not necessarily 90 degrees, if the bent movable joint is used for connection, more materials are wasted in connection, the structure cannot be flexibly adjusted, and the applicability is not strong.

The applicant has a prior application CN205745815U and discloses an angle-adjustable bent loose joint, which comprises a bent pipe, straight pipes connected to two ends of the bent pipe, a lock sleeve in threaded connection with the outer sides of the straight pipes and a rotary head rotatably connected in the lock sleeve; the rotating head comprises a rotating ball which is rotatably connected in the lock sleeve and a connecting end which is integrated with the rotating ball and is positioned outside the lock sleeve; the rotating head is provided with a water inlet and outlet through hole; the end part of the straight pipe is provided with a fixed groove; the fixing groove is provided with a sealing ring; the sealing ring is glued with the groove wall of the fixed groove; the inner wall of the straight pipe is connected with a silencing sleeve.

The application is a development improvement on the basis.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model provides an angle adjustable angle knee joint formula is loose joint for feedwater has solved the lower problem of knee joint formula loose joint flexibility.

In order to achieve the purpose, the utility model is realized by the following technical proposal:

the utility model provides an angle adjustable knee joint formula loose joint connects for feedwater, includes return bend, lock sleeve and turn round, the both ends of return bend are the straight tube section, the turn round passes through with the straight tube section lock sleeve interconnect, the turn round stretches out the outer part of lock sleeve is the linkage segment, the tip of straight tube section sets up an elastic connection cover, the both ends of elastic connection cover with the lock sleeve straight tube section sealing connection, the turn round rotationally inlays to be put in the straight tube section.

Preferably, a plurality of anti-falling bulges which are distributed annularly are arranged on the inner wall of the end part of one end part of the elastic connecting sleeve connected with the upper connecting section of the rotating head.

Preferably, the protruding height of each protrusion gradually increases from the end of the connecting sleeve to the inside.

Preferably, the outer side wall of the rotating head is sleeved with an annular sealing sheet, and when the rotating head is embedded in the straight pipe section, the annular sealing sheet is in sealing connection with the inner wall of the straight pipe section.

By adopting the technical scheme, the beneficial effects of the utility model are that:

the utility model is additionally provided with the elastic connecting sleeve, the turning head can be embedded into the straight pipe section of the elbow pipe during the installation, the elbow pipe and the turning head are connected through the elastic connecting sleeve, and the elastic connecting sleeve is fixedly installed through the lock sleeve and realizes the sealing connection between the elbow pipe and the turning head; due to the fact that the elastic connecting sleeve is used, the spherical part of the swivel is embedded into the straight pipe section in a targeted mode, the angle which is more suitable for installation can be adjusted according to requirements, and good sealing can be achieved through the structure of the elastic connecting sleeve and the locking sleeve.

Drawings

Fig. 1 is a schematic view of the overall structure of the embodiment of the present invention.

Detailed Description

The following detailed description will be given with reference to specific embodiments, so as to solve the technical problems by applying technical means, and to fully understand and implement the technical effects of the present invention.

Examples

Referring to fig. 1, an angle adjustable knee joint formula loose joint connects for feedwater, includes return bend 1, lock sleeve 2 and turn 3, the both ends of return bend 1 are straight tube section 11, turn 3 and straight tube section 11 pass through lock sleeve 2 interconnect, turn 3 stretches out the outer part of lock sleeve 2 is linkage segment 31, the tip of straight tube section 11 sets up an elasticity adapter sleeve 4, the both ends of elasticity adapter sleeve 4 with lock sleeve 2 straight tube section 11 sealing connection, turn 3 rotationally inlays to be put in straight tube section 11. Specifically, after the lock sleeve 2 is locked, because the elastic connecting sleeve 4 is of an elastic structure, sealing connection can be realized under the force application of the lock sleeve 2. The lock casing 2 can here be locked by a structure similar to a clip.

In this embodiment, a plurality of (only two in cross section are shown in fig. 1) anti-falling protrusions 41 are annularly distributed on the inner wall of the end portion of the elastic connecting sleeve 4 connected with the connecting section 31 of the rotor 3. The protruding height of each protrusion is gradually increased inwards from the end part of the connecting sleeve; the arrangement of the protrusion 41 enables the elastic connecting sleeve 4 to have the function of preventing the rotor 3 from falling off the straight pipe section 11 after the rotor 3 is embedded into the straight pipe section 11, so that the installation is convenient, and meanwhile, the elastic connecting sleeve also has a certain function of preventing the rotor 3 from excessively rotating;

in this embodiment, an annular sealing sheet 32 is sleeved on an outer side wall of the rotary head 3, and when the rotary head 3 is embedded in the straight pipe section 11, the annular sealing sheet 32 is connected with an inner wall of the straight pipe section 11 in a sealing manner. Specifically, the annular sealing sheet 32 is disposed around the rotor 3 and uniformly covers a part of the outer surface of the rotor 3; the annular sealing sheet 32 is arranged, and structurally, no matter what angle the rotary head 3 rotates to, a certain sealing property can be achieved between the rotary head 3 and the straight pipe section 11, and another sealing property is provided for the integral structure.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
