Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-3, a bedside handrail that can conveniently turn to, includes connecting

piece

1, 1 pot head of connecting piece is equipped with bedside handrail iron pipe 2, and the fixed welding of 1 other end of connecting piece has an internal connection section of thick bamboo 5, the interference of 5 inner walls of internal connection section of thick bamboo is connected with stopper 9, stopper 9 has pull rod 14 along horizontal direction sliding connection, the fixed welding of 14 one end of pull rod has shoulder 7, pull rod 14 leans on shoulder 7 one end activity cover to be equipped with reset spring 8, the effect of stopper (9) is that pull rod 14 compresses reset spring 8 smoothly when sliding along the horizontal direction.

And the pull rod 14 is fixedly welded with the mounting column 13 by one end of the limiting block 9, the total length of the pull rod 14 and the mounting column 13 is equal to the length of the inner connecting cylinder 5, so that the pull rod 14 and the mounting column 13 can be completely buried in the inner connecting cylinder 5, the cross section size of the convex shoulder 7 is smaller than the inner diameter of the inner connecting cylinder 5, and the convex shoulder 7 does not influence the sliding of the pull rod 14 in the connecting cylinder 5.

The erection column 13 interference is connected with handle 11, the handle 11 has been seted up mounting groove 12 by erection column 13 junction, and mounting groove 12 is the hexagon with erection column 13 cross sectional shape, 5 outer walls of an internal connection section of thick bamboo rotate and are connected with three-way pipe 3, three-way pipe 3 is as handrail and the relation of connection between three-way pipe 3 and the internal connection section of thick bamboo 5 for clearance fit, three-way pipe 3 has outer rectangular groove 4 by the circular array of 5 one end terminal surfaces of an internal connection section of thick bamboo, handle 11 has rectangular fixture block 10 by the circular array of 14 one end terminal surfaces of pull rod, and rectangular fixture block 10 highly equals inner rectangular groove 6 and outer rectangular groove 4 overall height.

The working principle is as follows:

when the three-way pipe joint is used, the inner rectangular groove 6 on the inner connecting cylinder 5 is aligned with the outer rectangular groove 4 on the three-way pipe 3, the pull rod 14 drives the rectangular fixture block 10 on the handle 11 to be clamped into the inner rectangular groove 6 on the inner connecting cylinder 5 and the outer rectangular groove 4 on the three-way pipe under the action of the reset spring 8 and the limiting block 9, at the moment, the inner connecting cylinder 5 and the outer connecting cylinder 3 cannot rotate relatively, when the three-way pipe 3 needs to be rotated, the handle 11 is pulled outwards by manpower, so that the rectangular fixture block 10 on the handle 11 and the inner rectangular groove 6 on the inner connecting cylinder 5 are separated from the outer rectangular groove 4 on the three-way pipe 3, the reset spring 8 is compressed at the moment, the three-way pipe 3 is rotated, after the outer rectangular groove 4 on the three-way pipe 3 is aligned with the outer rectangular groove 6 again, the handle 11 is loosened, the pull rod 14 drives the rectangular fixture block 10 on the handle 11 to be clamped into the inner rectangular groove 6 on the inner connecting cylinder 5 and the outer rectangular groove 4 on the three-way pipe 3 again under the action of the limiting block 9, at this time, the tee 3 is restored to the state where it cannot rotate freely along the inner joint cylinder 5.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
