Description

Technical Field

[0001] This utility model relates to the technical field of connection structures, specifically an anti-detachment connection structure for a telescopic bracket. Background Technology

[0002] Telescopic supports typically use multi-section sleeves as telescopic connections. However, when these sleeves are extended, smaller sleeves can easily detach from larger ones. Existing anti-detachment structures are usually integrally formed stepped protrusions on the tube body, but this method requires the sleeves to be installed in reverse. For sleeves with other components formed at the tube ends, this can cause installation difficulties. Without an anti-detachment structure, the sleeves may loosen during connection, resulting in certain defects in the actual use of telescopic supports. Therefore, this utility model proposes an anti-detachment connection structure for telescopic supports to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-detachment connection structure for telescopic brackets to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-detachment connection structure for a telescopic bracket, comprising:

[0005] A primary telescopic tube, wherein a threaded seat is fixedly glued to the outer wall of the lower end of the primary telescopic tube, and an anti-detachment seat is integrally formed on the inner wall of the lower end of the threaded seat.

[0006] A secondary telescopic tube, wherein the upper end of the secondary telescopic tube is movably disposed within the inner cavity of the primary telescopic tube;

[0007] An anti-detachment plate is connected to the upper end sidewall of the secondary telescopic tube;

[0008] An adjusting seat is screwed onto a threaded seat, and the inner cavity of the adjusting seat is provided with a self-locking seat;

[0009] The adjusting seat, when tightened, generates a supporting force on the self-locking seat, so that the self-locking seat locks onto the secondary telescopic tube.

[0010] Preferably, the anti-detachment seat is an annular protrusion structure with a right-angled triangular cross-section, and the length of the right-angled side of the anti-detachment seat is greater than the wall thickness of the first-stage telescopic tube.

[0011] Preferably, the upper sidewall of the secondary telescopic tube is provided with a docking hole, and a set of docking holes are symmetrically arranged. The inner sidewall of the anti-detachment plate is integrally formed with a docking post. When the anti-detachment plate is actually installed, the docking post is inserted into the docking hole. The docking post and the docking hole are interference fit. When the anti-detachment plate is actually installed, the inner sidewall of the anti-detachment plate is fitted to the outer sidewall of the secondary telescopic tube.

[0012] Preferably, the anti-detachment seat and the anti-detachment plate are interference fit, and when the secondary telescopic tube and the primary telescopic tube are actually connected, the lower end of the anti-detachment plate abuts against the right-angle side of the anti-detachment seat.

[0013] Preferably, the inner wall of the adjusting seat is integrally formed with an annular seat, and the outer wall of the self-locking seat is provided with an annular groove. During actual installation, the annular seat is movably disposed in the annular groove.

[0014] Preferably, the self-locking seat has an opening groove, and the two ends of the self-locking seat have a primary U-shaped groove and a secondary U-shaped groove, respectively, and the opening groove, the primary U-shaped groove and the secondary U-shaped groove are staggered.

[0015] Preferably, when the adjusting seat and the threaded seat are actually tightened, the end of the self-locking seat facing the first-stage U-groove abuts against the inclined surface of the anti-detachment seat, and at this time, the end of the self-locking seat facing the first-stage U-groove is forcefully held inward on the second-stage telescopic tube.

[0016] Preferably, the outer surface of the adjustment seat is integrally formed with anti-slip protrusions.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up an anti-detachment connection structure for the telescopic bracket, which is composed of a primary telescopic tube, a secondary telescopic tube, an anti-detachment plate, and an adjustment seat, and setting an anti-detachment seat on the lower end of the threaded seat on the primary telescopic tube, the anti-detachment plate and the anti-detachment seat abut against and limit the movement, thereby achieving the purpose of preventing the primary and secondary telescopic tubes from loosening, thus improving the stability of the structure in actual application.

The upper end of the secondary telescopic tube 2 is movably disposed in the inner cavity of the primary telescopic tube 1. The anti-detachment plate 3 is connected to the upper end side wall of the secondary telescopic tube 2. The adjusting seat 4 is screwed onto the threaded seat 5. A self-locking seat 6 is provided in the inner cavity of the adjusting seat 4. When the adjusting seat 4 is screwed tight, it generates a holding force on the self-locking seat 6, so that the self-locking seat 6 locks onto the secondary telescopic tube 2. Preferably, the anti-detachment seat 7 is an annular protrusion structure with a right-angled triangular cross-section, and the length of the right-angled side of the anti-detachment seat 7 is greater than the wall thickness of the primary telescopic tube 1.

[0034] Preferably, the upper sidewall of the secondary telescopic tube 2 is provided with a docking hole 8, and a set of docking holes 8 are symmetrically arranged. The inner sidewall of the anti-detachment plate 3 is integrally formed with a docking post 9. When the anti-detachment plate 3 is actually installed, the docking post 9 is inserted into the docking hole 8. The docking post 9 and the docking hole 8 are interference fit. When the anti-detachment plate 3 is actually installed, the inner sidewall of the anti-detachment plate 3 is fitted against the outer sidewall of the secondary telescopic tube 2.

[0035] Preferably, the anti-detachment seat 7 and the anti-detachment plate 3 are interference fit, and when the secondary telescopic tube 2 and the primary telescopic tube 1 are actually connected, the lower end of the anti-detachment plate 3 abuts against the right-angle side of the anti-detachment seat 7. By setting up an anti-detachment connection structure for the telescopic bracket composed of the primary telescopic tube 1, the secondary telescopic tube 2, the anti-detachment plate 3 and the adjusting seat 4, and setting the anti-detachment seat 7 on the lower end of the threaded seat 5 on the primary telescopic tube 1, the anti-detachment plate 3 and the anti-detachment seat 7 abut against and limit the movement, thereby achieving the purpose of preventing the primary telescopic tube 1 and the secondary telescopic tube 2 from loosening, thereby improving the stability of the structure in actual application.

[0036] In Example 2, based on Example 1, preferably, the inner wall of the adjusting seat 4 is integrally formed with an annular seat 10, and the outer wall of the self-locking seat 6 is provided with an annular groove 11.

Preferably, when the adjusting seat 4 and the threaded seat 5 are actually tightened, the end of the self-locking seat 6 facing the primary U-shaped groove 13 abuts against the inclined surface of the anti-loosening seat 7. At this time, the end of the self-locking seat 6 facing the primary U-shaped groove 13... One end of the first-stage U-shaped groove 13 is forced inward and clamps onto the second-stage telescopic tube 2. By setting a self-locking seat 6 in the inner cavity of the adjusting seat 4, and opening an opening groove 12, a first-stage U-shaped groove 13, and a second-stage U-shaped groove 14 on the self-locking seat 6, it is possible to facilitate the docking and installation of the self-locking seat 6 and the adjusting seat 4. At the same time, the inclined surfaces of the self-locking seat 6 and the anti-detachment seat 7 can generate a resisting force, thereby allowing the self-locking seat 6 to lock onto the second-stage telescopic tube 2, thus achieving the locking and positioning of the first-stage telescopic tube 1 and the second-stage telescopic tube 2.

[0038] The outer surface of the adjustment seat 4 is integrally molded with anti-slip protrusions 15.
