Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the three-dimensional gear horizontal / vertical inner tight direct threading pipe connection structure in the prior art has poor stability. In the process of irrigation with concrete, the screws are easily loosened by external forces, resulting There is a gap between the three-dimensional gear horizontal / vertical inner tight direct threading pipe connection structure and the threading pipe, and even the threading pipe falls off from the three-dimensional gear horizontal / vertical inner tight direct threading pipe connection structure, causing the threading to be blocked by concrete unavailable

Embodiment 1

[0034] Such as figure 1 , 2 As shown, the three-dimensional gear horizontal / vertical inner tight direct threading pipe connection structure in this embodiment includes a pipe body 1 and two clamps arranged near both ends of the pipe body, and each set of clamps includes a clamp band 2 And a fixing device for fixing the band, the fixing device includes a worm 3 and a casing 4, the band 2 is provided with a helical groove, the band is arranged on the inner side of the pipe body 1, and the pipe body 1 is connected with the clamp The contact part of the band 2 is provided with an opening, and the casing 4 passes through the opening on the pipe body and is fixed on one end of the band 2, and the other end of the band 2 passes through the case 4 and is exposed outside the body 1, and the worm 3. Parallel and tangentially arranged in the case 4 on the clamp band, and rotate with the outer edge of the case. The tooth groove of the band 2 meshes with the external thread of the worm 3,...

Embodiment 2

[0037] Such as image 3 , 4As shown, the three-dimensional gear horizontal / vertical inner tight direct threading pipe connection structure in this embodiment includes a pipe body 1, two clamps arranged at the positions near both ends of the pipe body 1, and two clamps arranged on the pipe body 1 A clamp cover 10 that wraps the first worm 8 and the casing 4 of the two clamps, each set of clamps includes a clamp band 2, a worm and a cover 4, and the clamp band 2 is provided with helical teeth Groove, the clamp band is set on the inner side of the tube body 1 close to the inner wall of the tube body, the contact part of the tube body 1 and the clamp band 2 is provided with an opening, and the cover 4 passes through the opening on the tube body and is fixed on the clamp One end of the band 2, and the other end of the band 2 passes through the casing 4 and is exposed outside the pipe body 1. There are two worms, which are the first worm 8 and the second worm 9 respectively. The ho...

Embodiment 3

[0040] Such as Figure 5 As shown, the three-dimensional gear horizontal / vertical inner tight direct threading pipe connection structure of this embodiment is basically the same as the first two three-dimensional gear horizontal / vertical inner tight direct threading pipe connection structures, the difference is that in An annular protrusion 6 for accommodating the clamp band is provided at the contact position of the pipe body 1 with the clamp band. The clamp band 2 is arranged in the annular protrusion 1, so that a threading pipe with a larger radius can be accommodated without increasing the inner diameter of the pipe body. In addition, when the clamp band fixes the threading pipe, the annular protrusion can clamp the clamp band to prevent the clamp band from being dislocated, or the band from being separated from the pipe body due to the action of external force. Therefore, the annular protrusion can improve the stability and tightness of the three-dimensional gear horizon...

Abstract

The invention discloses a three-dimensional gear transverse / vertical inside-tightening direct-type casing pipe connection structure. The connection structure comprises a pipe body and a clamp. The clamp comprises a clamp strap and a fixing device for fixing the clamp strap. The fixing device comprises a worm and a housing, the clamp strap is arranged on the inner side of the pipe body, an open hole is formed in the position, in contact with the clamp strap, of the pipe body, the housing penetrates through the open hole in the pipe body to be fixed at one end of the clamp strap, the other end of the clamp strap penetrates into the pipe body or is exposed outside the pipe body by penetrating through the housing, the worm is arranged inside the housing and matched with the outer edge of the housing in a rotating mode, and a tooth groove of the clamp strap is meshed with external threads of the worm. Original point contact is changed to surface contact in the connection structure, the stress area is large, loosening does not easily occur, stability is good, fixing capacity is high, impact of external force can be resisted, concrete is prevented from entering the connection structure, construction can be carried out in the transverse and longitudinal directions, good practicability is achieved, the structure is simple, work efficiency is improved, and work cost is reduced.

Description

technical field [0001] The invention relates to a connection structure, in particular to a three-dimensional gear horizontal / vertical inner tight direct threading pipe connection structure. Background technique [0002] The three-dimensional gear horizontal / vertical inner tight direct threading pipe connection structure is a component used to connect two threading pipes together. [0003] The threading pipe is the pipe used for the power supply line to pass through. During the construction of the building, the threading pipe is arranged in the wall, roof or building in advance, which is convenient for the later electrician wiring and construction, and also facilitates the later circuit maintenance. Moreover, the wires are arranged inside the wall, which is not only beautiful, but also improves safety. In the process of arranging the threading pipes, two threading pipes need to be connected together with a three-dimensional gear horizontal / vertical inner tight direct threa...
