Description

Technical Field

[0001] The present invention relates to the technical field of component connection, and in particular to an assembly method of a connector for realizing non-coupled free rotation of two side connectors. Background Art

[0002] Component connection is a common phenomenon. Different components can be assembled into an assembly using various connection forms according to the application purpose. Among them, there is an application scenario of connecting components: the lengths of the connectors on both sides of the connection are undetermined, and the connectors on both sides of the connection can achieve independent free rotation with each other. At the same time, it is also required that the connection of the assembled components can withstand axial tensile and compressive forces, that is, it is required that the connector can withstand axial force loads. For example, in the construction of tunnel pipe shed bolts, the local front end of the bolt entering the rock can freely rotate with the drill pipe to effectively break the rock and realize the rapid entry of the bolt into the rock. The remaining bolt sections only need to move forward under the action of the tensile force of the front bolt section, so as to avoid the overall rotation of the bolt and improve the construction efficiency. It is necessary to quickly assemble a connector that can not only withstand axial forces to meet the synchronous translational entrainment movement of its two side connectors, but also meet the non-coupled free rotation of its two side connectors for its popularization and application. Summary of the Invention

[0003] The purpose of the present invention is to provide an assembly method of a connector for realizing non-coupled free rotation of two side connectors according to the deficiencies of the above-mentioned prior art. The arc-shaped slider is installed in the card slot of the insertion ring through the arc-shaped through groove. When driving the second connector to rotate the insertion ring thereon in the first annular groove of the first connector, the arc-shaped slider can be driven to rotate in the second annular groove of the first connector, so that the first connector and the second connector can achieve non-coupled independent free rotation in the circumferential direction.

[0025] The features of the present invention and other related features are further described in detail below with reference to the accompanying drawings through examples for the understanding of those skilled in the same industry:

[0026] As Figures 1-11 shown, the reference numerals 1 - 11 in the figure respectively represent: the first connecting member 1, the second connecting member 2, the annular groove 3, the insertion ring 4, the arc - shaped through - groove 5, the card slot 6, the card plate 7, the arc - shaped slider 8, the through cavity 9, the spring 10, and the limiting rod 11.

[0027] Example: As Figures 1-11 shown, this embodiment relates to an assembly method of a connecting body for realizing non - coupled free rotation of two - side connecting members, and its assembly method includes the following steps:

[0028] S1: Connect and assemble the first connecting member 1 and the second connecting member 2. Among them, both the first connecting member 1 and the second connecting member 2 are hollow rods. One end of the first connecting member 1 is provided with an installation groove 3. The installation groove 3 includes a first annular groove arranged circumferentially along the end face of the first connecting member 1 and a second annular groove arranged circumferentially along the inner circumference of the side wall of the first connecting member 1. The first annular groove is communicated with the second annular groove. The second annular groove is communicated with the outside of the first connecting member 1 through a plurality of arc-shaped through grooves 5 on its outer side. And the arc-shaped through grooves 5 are arranged circumferentially along the side face of the first connecting member 1, that is, the arc-shaped through grooves 5 and the second annular groove are arranged on the same cross-section of the first connecting member 1, and the width of the arc-shaped through groove 5 is the same as the width of the second annular groove. In this embodiment, the number of the arc-shaped through grooves 5 is three. Of course, according to actual needs, it can also be other numbers. One end face of the second connecting member 2 is provided with an insertion ring 4 adapted to the first annular groove along its circumference. The insertion ring 4 is provided with clamping grooves 6 whose number and positions respectively correspond to the number and positions of the arc-shaped through grooves 5 along its circumference. And the width of the clamping groove 6 is the same as the width of the second annular groove. The depth of the clamping groove 6 is equal to the thickness of the insertion ring 4. The arc length of the clamping groove 6 corresponds to the arc length of the arc-shaped through groove 5. Two clamping plates 7 are respectively arranged on both sides in the clamping groove 6.

[0029] S2: Align the insertion ring 4 of the second connecting member 2 with the first annular groove of the first connecting member 1 and insert the insertion ring 4 into the first annular groove; rotate the second connecting member 2 so that the position of the clamping groove 6 on the insertion ring 4 is aligned with the position of the arc-shaped through groove 5 on the first connecting member 1.

[0030] S3: Put the arc-shaped slider 8 into the clamping groove 6 of the insertion ring 4 of the second connecting member 2 through the arc-shaped through groove 5 of the first connecting member 1. Among them, the size and shape of the arc-shaped slider 8 are adapted to the size and shape of the second annular groove. A through cavity 9 is arranged along the arc length direction of the arc-shaped slider 8. In this embodiment, the cross-sectional shape of the through cavity 9 is a regular hexagon (it can also be other shapes). Two limiting rods 11 are respectively installed at both ports of the through cavity 9. The limiting rods 11 are provided with U-shaped openings adapted to the clamping plates 7 at one ends facing outside the ports of the through cavity 9. The two limiting rods 11 are connected by a spring 10. In the state where the two limiting rods 11 are completely pressed into the inside of the through cavity 9 of the arc-shaped slider 8, put the arc-shaped slider 8 into the clamping groove 6 of the insertion ring 4 of the second connecting member 2 through the arc-shaped through groove 5 of the first connecting member 1. At this time, the positions of the U-shaped openings of the two limiting rods 11 on both sides of the through cavity 9 just coincide with the positions of the two clamping plates 7 in the clamping groove 6 on the insertion ring 4; finally, release the extrusion load acting force on the limiting rods 11, and the limiting rods 11 move outward to the outside of the through cavity 9 under the deformation load of the spring 10, so that the clamping plates 7 are inserted into the U-shaped openings of the limiting rods 11.

[0031] By driving the second connecting member 2 to rotate the insertion ring 4 thereon within the first annular groove of the first connecting member 1, the arc-shaped slider 8 is driven to rotate within the second annular groove of the first connecting member 1. At the same time, since the cross-sectional dimension of the arc-shaped slider 8 is larger than the cross-sectional dimension of the card slot 6 of the insertion ring 4, it can prevent the insertion ring 4 from being pulled out from the inner cavity of the first annular groove, thereby enabling the axial load transfer between the first connecting member 1 and the second connecting member 2, and causing the two to perform axial synchronous translation movements. Since the arc-shaped slider 8 can rotate circumferentially within the second annular groove, it can simultaneously satisfy the circumferential rotation of the insertion ring 4 within the first annular groove, so that the first connecting member 1 and the second connecting member 2 can achieve non-coupled independent free rotation in the circumferential direction.

[0032] This embodiment also has the following beneficial effects: simple structure and convenient use; the arc-shaped slider is installed in the card slot of the insertion ring through the arc-shaped through groove. When driving the second connecting member to rotate the insertion ring thereon within the first annular groove of the first connecting member, the arc-shaped slider can be driven to rotate within the second annular groove of the first connecting member, enabling the first connecting member and the second connecting member to achieve non-coupled independent free rotation in the circumferential direction.

[0033] Although the above embodiments have detailed the concept and embodiments of the present invention's purpose with reference to the accompanying drawings, those of ordinary skill in the art can recognize that various improvements and transformations can still be made to the present invention without departing from the scope defined by the claims. Therefore, they are not elaborated one by one here.
