Description

a telescoping rod

technical field

The utility model relates to a telescopic rod, in particular to a telescopic rod which can be fixed between two opposite wall surfaces through telescopic adjustment of length.

Background technique

The telescopic tube generally consists of two round tubes with different outer diameters. The connecting end of the inner pipe provided with the fastening device is inserted into the connecting end of the outer pipe. When in use, the length is adjusted as required, and the inner pipe and the outer pipe are relatively fixed. The end of the telescopic tube is also provided with an end sleeve, and a friction surface is set on the end surface of the end sleeve, and the friction force generated after the two ends of the telescopic rod are pressed against the wall makes the telescopic rod fixed between two parallel walls. The method does not need to damage the wall, and it is easy to install. It can be used to hang lighter items, such as towels, curtains, shower curtains, etc. It is very suitable for use in homes, hotels, and shopping malls. The telescopic rods of this method must face the wall The greater the pressure, the greater the friction between the telescopic rod and the wall, and the heavier the hanging items it can bear.

The existing telescopic rod is processed with internal threads on the outer circumference of the inner tube connection end, and at the same time, a matching external thread is processed on the inner wall of the outer rod connection end. When installing, the inner and outer tubes are relatively rotated to make the telescopic rod stretch and The two ends of the cover are tight on the wall. The main disadvantage of this kind of telescopic rod is that it is not elastic after installation, and its two ends cannot be firmly pressed against the wall, and it is easy to fall; and this kind of telescopic rod is not easy to install, and it is easy to damage the wall when rotating the inner and outer tubes .

Utility model content

The utility model provides a telescopic rod, the main purpose of which is to overcome the disadvantages that the existing telescopic rod cannot be firmly pressed against the wall, is easy to fall, is difficult to install, and is easy to damage the wall during installation.

The utility model adopts the following technical solutions:

A telescopic rod, which is formed by at least one section of outer tube and one section of inner tube that can be telescopically socketed, and the two ends of the telescopic rod are provided with end caps that can be pressed against the opposite wall, and the connecting end of the inner tube is passed through a The fastener is connected to the inner side wall of the connecting end of the outer pipe, the inner pipe is slidingly connected with the fastener, and a mounting bracket is provided between the connecting end of the inner pipe and the fastener so that the outer pipe and the inner pipe slide against each other. spring.

For the aforementioned telescopic rod, the end of the fastener connected to the inner wall of the outer tube forms an eccentric rod, and an eccentric snap ring is clamped on the eccentric rod, and the outer tube and the inner tube are connected between the eccentric rod and the outer tube through the eccentric snap ring. The clamping force generated between the inner walls of the pipe is relatively positioned to connect.

Further, the connecting end of the inner tube is sleeved on the fastener, and the fastener is provided with an axially extending chute, and the connecting end of the inner tube is provided with a stamped inwardly recessed embedding part , the embedding part is slidably arranged in the chute of the fastener.

Furthermore, a protruding ring is provided on the outer periphery of the fastener, and the spring is sleeved on the fastener and sandwiched between the protruding ring and the end surface of the connecting end of the inner tube, and the spring is connected to the inner tube A spacer is provided between the end faces of the ends.

In the aforementioned telescopic rod, the connecting end of the outer tube forms an oblique middle sleeve that is smoothly transitioned to the inner tube.

In the aforementioned telescopic rod, the end surface of the end cover in contact with the wall forms a rubber friction surface.

As can be seen from the above description of the structure of the utility model, compared with the prior art, the utility model has the following advantages:

1. Due to the elasticity of the telescopic rod after installation, the two ends of the telescopic pipe can be fastened to the opposite wall through the spring between the inner and outer pipes. Compared with the prior art, the fixing method is more reasonable and reliable;

2. When using external force to force the inner and outer tubes to rotate relatively, the eccentric snap ring is clamped between the eccentric rod of the fastener and the inner wall of the outer tube, so that the inner and outer tubes are relatively fixed, and the inner and outer tubes When the tube rotates in the opposite direction, the inner and outer tubes can be relatively loosened so as to adjust the length between the two to adapt to different places, and the clamping force connected to the wall is mainly provided by the spring. Very convenient.

Detailed ways

The utility model provides a telescopic rod which can be fixed between two opposite wall surfaces, and is used for hanging daily necessities such as towels and bath towels. Below with reference to Fig. 1 and Fig. 2 illustrate the specific embodiment of the present utility model.

Referring to Figures 1 and 2, a telescopic rod 7 is formed by telescopically connecting a section of outer tube 1 and a section of inner tube 2, and the two ends of the telescopic rod 7 are provided with a wall that can be pressed against the opposite wall. The end caps 61, 62 are provided with rubber friction surfaces 610, 620 on the contact surfaces of the end caps 61, 62 and the wall respectively.

The connecting end of the inner tube 2 is connected to the inner side wall of the connecting end of the outer tube 1 through a fastener 3, the inner tube 2 is slidingly connected with the fastener 3, and the connecting end of the inner tube 2 is connected to the fastener. 3 is provided with a spring 33 to make the outer tube 1 and the inner tube 2 slide against each other.

The end connecting the fastener 3 with the inner wall of the outer tube 1 forms an eccentric rod 34, and an eccentric snap ring 4 is clamped on the eccentric rod 34. 34 is relatively positioned and connected with the tightening force generated between the inner wall of the outer tube 1. The connecting end of the inner pipe 2 is sleeved on the fastener 3, and the fastener 3 is provided with an axially extending slide groove 32, and the connecting end of the inner pipe 2 is provided with a stamped inwardly recessed embedding. The setting portion 22 is slidably disposed in the slide groove 32 of the fastener 3 . A protruding ring 35 is provided on the outer periphery of the fastener 3, the spring 33 is sleeved on the fastener 3, and is sandwiched between the protruding ring 35 and the end surface of the connecting end of the inner tube 2, and the spring 33 is connected to the inner tube 2 A spacer 5 is provided between the end faces of the ends.

Thus, a stretchable and length-adjustable structure is formed between the outer tube 1 and the inner tube 2 , and after the outer tube 1 and the inner tube 2 are relatively fixed, there is a certain degree of elasticity between the two through the action of the spring 33 .

The connecting end of the outer tube 1 forms a slanted sleeve with a smooth transition to the outer surface of the inner tube 2 to increase the convenience and safety of use.

When external force is used to force the inner tube 2 and the outer tube 1 to rotate relatively, the eccentric snap ring 4 is clamped between the eccentric rod 34 of the fastener 3 and the inner wall of the outer tube 1, so that the inner tube 2 and the outer tube 1 If the inner tube 2 and the outer tube 1 are rotated in the opposite direction, the two can be relatively loosened so as to adjust the length between the two to adapt to different places. The force is mainly provided by the spring 33 between the fastener 3 and the end face of the inner tube 2 .

The above is only a specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto, any non-substantial modification of the utility model by using this concept should be an act of violating the protection scope of the present utility model .
