Description

Expansion joint

Technical Field

The utility model belongs to the technical field of furniture is assembled and specifically relates to an expansion joint is related to.

Background

Traditional furniture installation pipe adopts the screw to fix when assembling usually, consequently assembles the speed slower to the screw fixation also can be because of screw thread wearing and tearing, thereby makes the phenomenon of slippage appear in furniture installation pipe, is unfavorable for the permanent use of furniture, and in case fixed in traditional furniture installation pipe simultaneously, just can't carry out the flexible regulation of length according to actual demand, and the suitability is relatively poor.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve the above-mentioned problem of coming, provide a telescopic joint for this reason, including outer tube, inner tube and telescopic joint body, the inner tube is inserted and is established in the outer tube, the telescopic joint body sets up in inner tube and outer tube handing-over department, the lower extreme of telescopic joint body is provided with the knob, corresponding U-shaped groove around being provided with on the telescopic joint body, be provided with the stuck point on the inner wall of telescopic joint body, the stuck point sets up the position department of being close to the U-shaped groove, be provided with the stuck point hole corresponding with the stuck point on the outer tube.

Preferably, the outer tube, the inner tube and the telescopic joint body may be provided in a circular structure.

The utility model has the advantages that: the utility model has the advantages of reasonable design, convenient to use can carry out assembling of furniture installation pipe fast, also can prevent the phenomenon that the slippage appears in the furniture installation pipe simultaneously, and the utility model discloses can be according to the flexible length of adjusting the pipe of actual demand to the suitability of furniture installation pipe has been improved.

In the figure: 1. an outer tube; 2. an expansion joint body; 3. an inner tube; 4. a knob; 5. a U-shaped groove; 6. sticking points; 7. a click hole.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature of the present specification may be replaced by another equivalent or alternative feature serving a similar purpose, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

The telescopic joint shown in fig. 1, 2, 3 and 4 comprises an outer pipe 1, an inner pipe 3 and a telescopic joint body 2, wherein the inner pipe 3 is inserted into the outer pipe 1, the telescopic joint body 2 is arranged at the joint of the inner pipe 3 and the outer pipe 1, a knob 4 is arranged at the lower end of the telescopic joint body 2, a front U-shaped groove 5 and a rear U-shaped groove 5 which correspond to each other are arranged on the telescopic joint body 2, a clamping point 6 is arranged on the inner wall of the telescopic joint body 2, the clamping point 6 is arranged at a position close to the U-shaped groove 5, and a clamping point hole 7 corresponding to the clamping point 6 is arranged on the outer pipe 1.

As shown in fig. 5, the outer tube 1, the inner tube 3 and the telescopic joint body 2 may be provided in a circular structure.

In the use, peg graft the inner tube 3 in the outer tube 1, on the outer tube 1 was established to the telescopic joint body 2 cover to block in checkpoint hole 7 through stuck point 6, make telescopic joint body 2 fix on outer tube 1, when the length of furniture installation pipe need be adjusted, only need to twist knob 4, make inner tube 3 outwards stretch or inwards zoom, after adjusting to suitable length, twist knob 4 again, thereby make knob 4 chucking inner tube 3 fix, thereby realize the length adjustment of furniture installation pipe with this.

The U-shaped groove 5 can increase the elasticity of the position of the clamping point 6, so that the clamping point 6 is clamped in the clamping point hole 7.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
