[0031] Through the arrangement of the positioning piece 103, the steel pipe body 101 can be positioned and clamped, so that the installation stability of the steel pipe body 101 is guaranteed, and the overall operation is rapid and convenient.

[0032] Through the arrangement of the reinforcing piece 104, the connecting portion of the steel pipe body 101 and the connecting sleeve 102 can be filled, and after installation is completed, the bending resistance of the connecting portion of the steel pipe body 101 and the connecting sleeve 102 can be significantly improved.

[0033] Embodiment 2

[0034] Refer to Figs. 3-5 For the second embodiment of the utility model, the embodiment is based on the previous embodiment.

[0035] Specifically, the outer ring of the steel pipe body 101 is fixedly connected with a convex column 101a, a limiting groove 101a-1 is formed in the surface of the convex column 101a, a first positioning hole 101a-2 is formed in the surface of the convex column 101a, and the outer ring of the steel pipe body 101 is fixedly connected with a clamping seat 101b.

[0036] The inside of the connecting sleeve 102 is provided with a receiving groove 102a.

[0037] The positioning piece 103 includes a displacement rod 103a, the displacement rod 103a is slidably connected on the steel pipe body 101, and an arc groove 103a-1 is formed in the surface of the displacement rod 103a.

[0038] One end of the displacement rod 103a is fixedly connected with a clamping rod 103a-2, and cooperates with the first positioning hole 101a-2, and the outer side of the clamping rod 103a-2 is provided with an inclined groove 103a-2a.

[0039] The diameter of the displacement rod 103a is greater than that of the clamping rod 103a-2.

[0040] Through the setting of the clamping rod 103a-2 and the first positioning hole 101a-2, the clamping rod 103a-2 can be inserted into the first positioning hole 101a-2 in the installed state, so as to position the convex column 101a and avoid the random sliding displacement of the convex column 101a.

[0041] The one end of the convex column 101a is designed as a round corner, which is matched with the inclined groove 103a-2a, so that when the steel pipe body 101 is pushed in, the round corner of the convex column 101a contacts the inclined groove 103a-2a, thereby extruding the clamping rod 103a-2 to automatically move up. Since the inclined groove 103a-2a is only arranged on one side of the clamping rod 103a-2, the steel pipe body 101 can be conveniently slid into the installation state, but cannot be slid out of the installation state.

[0042] The positioning member 103 further includes an auxiliary block 103b and an inclined rod 103c. The auxiliary block 103b is arranged outside the connecting sleeve 102. One end of the inclined rod 103c is fixedly connected to the surface of the auxiliary block 103b and is matched with the limiting groove 101a-1. The inner part of the auxiliary block 103b is provided with a sliding groove 103b-1 matched with the displacement rod 103a.

[0043] Through the setting of the inclined rod 103c and the limiting groove 101a-1, the convex column 101a can be positioned and installed in the state that the inclined rod 103c is inserted, so as to effectively avoid the random sliding displacement of the convex column 101a and the steel pipe body 101.

[0044] One end of the displacement rod 103a is designed as a T shape, the inner cavity of the sliding groove 103b-1 is designed as a T shape, and the outer side of the inner wall of the sliding groove 103b-1 is arranged as an inclination. When the displacement rod 103a moves outward, it will contact the inner inclined surface of the sliding groove 103b-1, so as to divide the vertical contact force, thereby facilitating the outward displacement of the auxiliary block 103b and the inclined rod 103c.

[0045] The surface of the inclined rod 103c is sleeved with a spring 103c-1. The spring 103c-1 is arranged in the receiving groove 102a. One end of the spring 103c-1 is fixedly connected to the inner wall of the receiving groove 102a, and the other end of the spring 103c-1 is fixedly connected to the surface of the inclined rod 103c.

[0046] Through the setting of the spring 103c-1, the inclined rod 103c can be provided with elastic support force, so as to avoid the random sliding displacement of the inclined rod 103c under the action of no external force.

[0047] The inner wall of the receiving groove 102a is clamped and connected with a protective cover. The protective cover covers the spring 103c-1. When the protective cover is detached, the spring 103c-1 in the receiving groove 102a can be maintained and replaced by the worker.

[0048] The reinforcing member 104 comprises a reinforcing ring 104a which is slidingly connected to the inner part of the connecting sleeve 102, and the outer ring of the reinforcing ring 104a is rotationally connected with a clamping block 104a-1 which cooperates with the clamping seat 101b.

[0049] The number of the clamping blocks 104a-1 is two, and they are symmetrically distributed on the reinforcing ring 104a.

[0050] The connecting sleeve 102 is provided with a pressing groove at both ends, and cooperates with the clamping block 104a-1, when the clamping block 104a-1 is horizontally arranged, the clamping block 104a-1 will be clamped into the clamping seat 101b to complete the positioning and anti-disengagement, when the clamping block 104a-1 is rotationally arranged into the pressing groove, the clamping block 104a-1 will be in an inclined state and disengaged from the clamping seat 101b.

[0051] Through the arrangement of the clamping block 104a-1 and the clamping seat 101b, the reinforcing ring 104a and the steel pipe body 101 can be positioned and connected in the clamped state.

[0052] The outer ring of the reinforcing ring 104a is provided with a second positioning hole 104a-2 which cooperates with the arc groove 103a-1.

[0053] One end of the reinforcing ring 104a is designed as a rounded corner, when the reinforcing ring 104a moves inward and contacts the displacement rod 103a, the rounded corner surface of the reinforcing ring 104a contacts the arc groove 103a-1 on the displacement rod 103a to press and displace the displacement rod 103a outward, which is beneficial to clamping and installing the reinforcing ring 104a, and for the same reason, when the reinforcing ring 104a is driven to displace outward, the inner wall of the second positioning hole 104a-2 will contact the arc groove 103a-1 to generate a pressing force on the displacement rod 103a and drive the displacement rod 103a to displace.

[0054] The inner ring of the reinforcing ring 104a is provided with a recess 104a-3 which cooperates with the protruding column 101a.

[0055] The inner wall of the connecting sleeve 102 is provided with a horizontal groove which has the same specification as the recess 104a-3 and cooperates with the protruding column 101a.

[0056] Through the arrangement of the recess 104a-3 and the protruding column 101a, the positioning and installation effect can be achieved, after the steel pipe body 101 and the connecting sleeve 102 are butt-jointed, the angle of the reinforcing ring 104a is only adjusted to align the recess 104a-3 and the protruding column 101a, and then the reinforcing ring 104a can be accurately pushed into installation.

[0057] In use, first drive the reinforcing ring 104a to move towards the connecting sleeve 102, one end of the reinforcing ring 104a first contacts the arc groove 103a-1, so that the displacement rod 103a is automatically moved outward, the clamping rod 103a-2 is synchronously moved, then the reinforcing ring 104a contacts the inclined groove 103a-2a, continues to push the displacement rod 103a to move outward, until the reinforcing ring 104a is placed into the connecting sleeve 102, the second positioning hole 104a-2 is aligned with the displacement rod 103a, the displacement rod 103a is reset into the second positioning hole 104a-2, the positioning and installation of the reinforcing ring 104a are completed.

[0058] Move the steel pipe body 101, drive the convex column 101a to move towards the connecting sleeve 102, under the cooperation of the groove 104a-3 and the convex column 101a, the steel pipe body 101 is accurately and stably pushed in, and the moving convex column 101a contacts the inclined groove 103a-2a, presses the clamping rod 103a-2 and the displacement rod 103a to move outward, until the clamping rod 103a-2 is aligned with the limiting groove 101a-1.

[0059] In the above process, when the displacement rod 103a is forced to move outward, it presses the auxiliary block 103b to generate displacement, and the displacement rod 103a slides in the sliding groove 103b-1, thereby linking the inclined rod 103c to displace, and the spring 103c-1 is compressed, when the force on the displacement rod 103a disappears, under the elastic support of the spring 103c-1, the displacement rod 103a is reset.

[0060] In the state that the clamping rod 103a-2 is aligned with the limiting groove 101a-1, the inclined rod 103c is also in the aligned state with the limiting groove 101a-1, at this time, under the elastic support of the spring 103c-1, the clamping rod 103a-2 is reset into the limiting groove 101a-1, the inclined rod 103c is reset into the limiting groove 101a-1, the quick locking and installation of the steel pipe body 101 are completed, then the clamping block 104a-1 is rotated to be clamped into the clamping seat 101b for reinforcement protection, which effectively improves the installation stability of the steel pipe body 101, and the reinforcing part 104 can effectively enhance the bending resistance of the connection between the steel pipe body 101 and the connecting sleeve 102.

[0061] When it is necessary to disassemble the steel pipe body 101, the worker only needs to drive the clamping block 104a-1 to rotate to be separated from the clamping seat 101b, and then applies force again, the clamping block 104a-1 contacts the connecting sleeve 102, generates a counterforce on the reinforcing ring 104a, so that the second positioning hole 104a-2 contacts the arc groove 103a-1, drives multiple displacement rods 103a to be actively moved outward, until the clamping rod 103a-2 is separated from the first positioning hole 101a-2, and with the action of the displacement rod 103a, the inclined rod 103c is also separated from the limiting groove 101a-1, in this state, the steel pipe body 101 can be moved to be separated from the connecting sleeve 102, and the quick disassembly operation is completed.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
