Description

Technical Field

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

[0002] Component connection is a common phenomenon. According to the application purpose, different components can be assembled into an assembly by various connection forms. Among them, there is an application scenario of connecting components: the lengths of the connecting pieces on both sides of the connection are undetermined, and the connecting pieces on both sides of the connection can independently rotate freely with respect to 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 connection body 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 rest of the bolt section only needs to make a translational movement forward under the tensile force of the front bolt section, so as to avoid the overall rotation of the bolt and improve the construction efficiency. Therefore, an assembly connection form is required that can not only withstand axial forces to meet the synchronous translational connected movement of the two-side connecting pieces, but also meet the non-coupled free rotation of the two-side connecting pieces, and this assembled structure meets the requirement of convenient disassembly. Summary of the Invention

[0003] The object of the present invention is to provide a detachable assembly method for realizing non-coupled free rotation of two-side connecting pieces 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 an arc-shaped through groove. When driving the second connecting piece to rotate the insertion ring thereon in the first annular groove of the first connecting piece, the arc-shaped slider can be driven to rotate in the second annular groove of the first connecting piece, so that the first connecting piece and the second connecting piece can realize non-coupled independent free rotation in the circumferential direction.

[0004] The object of the present invention is achieved by the following technical solutions:

[0005] A detachable assembly method for realizing non-coupled free rotation of two-side connecting pieces, characterized in that the assembly method includes the following steps:

[0006] (S1)Connect and assemble the first connecting piece and the second connecting piece; wherein, one end of the first connecting piece is provided with an installation groove, and the installation groove includes a first annular groove arranged circumferentially along the end face of the first connecting piece and a second annular groove arranged circumferentially along the inner circumference of the side wall of the first connecting piece. The first annular groove is communicated with the second annular groove, and the second annular groove is communicated with the outside of the first connecting piece through a plurality of arc-shaped through grooves on its outer side. The arc-shaped through grooves are arranged circumferentially along the side face of the first connecting piece; a plug ring adapted to the first annular groove is arranged circumferentially along one end face of the second connecting piece, and a clamping groove with the same number and position as the arc-shaped through grooves is arranged circumferentially on the plug ring. A clamping plate is arranged on each of the two sides in the clamping groove.

[0007] (S2)Align the plug ring of the second connecting piece with the first annular groove of the first connecting piece and insert the plug ring into the first annular groove; rotate the second connecting piece so that the position of the clamping groove on the plug ring is aligned with the position of the arc-shaped through groove on the first connecting piece.

[0008] (S3)Put the arc-shaped slider into the clamping groove of the plug ring of the second connecting piece through the arc-shaped through groove of the first connecting piece; wherein, a through cavity is arranged along the arc length direction of the arc-shaped slider, and a limiting rod is installed at each of the two ports of the through cavity. An opening adapted to the clamping plate is arranged at one end of the limiting rod facing outside the port of the through cavity. The two limiting rods are both connected to a connecting piece arranged in the middle of the through cavity through a connecting rod. The connecting rod is movably connected with the limiting rod and the connecting piece. A limiting hole is communicated with the outside of the arc-shaped through groove on one side of the middle of the through cavity, and a limiting piece connected to the connecting piece is installed in the limiting hole; by adjusting the position of the limiting piece in the limiting hole, the limiting rod is driven to move outside the through cavity so that the opening is connected with the clamping plate.

[0009] The limiting piece is a control screw. The limiting hole includes a smooth hole communicated with the through cavity and a threaded hole communicated with the smooth hole. The internal thread of the threaded hole matches the external thread of the control screw. The connecting piece includes a collar and two cushion plates respectively installed at both ends of the collar. The two cushion plates are a circular cushion plate for closing the end of the collar and an annular cushion plate sleeved on the control screw; when the control screw is rotated, the control screw rotates circumferentially in the collar and the control screw moves along the axis direction of the limiting hole.

[0010] Before placing the arc-shaped slider into the arc-shaped through groove, rotate the control screw to retract the limiting rod back into the through cavity; place the arc-shaped slider into the card slot of the insertion ring of the second connecting piece through the arc-shaped through groove of the first connecting piece, and align the opening positions on the limiting rods at both ports of the through cavity with the positions of the two clamping plates in the card slot; rotate the control screw to move the limiting rod out of the through cavity so that the clamping plate is inserted into the opening of the limiting rod, and tighten the control screw so that the control screw is completely placed inside the slider.

[0029] The features of the present invention and other related features are further described in detail below with reference to the accompanying drawings through embodiments, so as to facilitate the understanding of those skilled in the same industry:

[0030] As Figure 1-14 shown, the markings 1-19 in the figure respectively represent: the first connecting member 1, the second connecting member 2, the installation groove 3, the insertion ring 4, the arc-shaped through groove 5, the clamping groove 6, the clamping plate 7, the arc-shaped slider 8, the through cavity 9, the control screw 10, the limiting rod 11, the collar 12, the connecting rod 13, the backing plate 14, the rotating shaft 15, the trapezoidal empty groove 16, the threaded hole 17, the smooth hole 18, and the bolt rod 19.

[0031] Embodiment: As Figure 1-14 shown, this embodiment relates to a detachable assembly method for realizing the non-coupled free rotation of the two-side connecting members, and the assembly method includes the following steps:

[0032] 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 grooves 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 grooves 6 is the same as the width of the second annular groove. The depth of the clamping grooves 6 is equal to the thickness of the insertion ring 4. The arc length of the clamping grooves 6 corresponds to the arc length of the arc-shaped through grooves 5. A clamping plate 7 is provided on each of the two sides in the clamping grooves 6.

[0033] 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 positions of the clamping grooves 6 on the insertion ring 4 are aligned with the positions of the arc-shaped through grooves 5 on the first connecting member 1.

[0034] S3: Place the arc-shaped slider 8 into the card slot 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. An open cavity 9 is provided along the arc length direction of the arc-shaped slider 8. In this embodiment, the cross-sectional shape of the open cavity 9 is a regular hexagon (it can also be other shapes). A limiting rod 11 is installed at each of the two ports of the open cavity 9. A U-shaped opening that cooperates with the card board 7 is provided at one end of the limiting rod 11 facing outside the port of the open cavity 9. Both limiting rods 11 are connected to a connecting member provided in the middle of the open cavity 9 through a connecting rod 13. The connecting rod 13 is movably connected to both the limiting rod 11 and the connecting member. A limiting hole is communicated on one side of the middle of the open cavity 9 facing outside the arc-shaped through groove 5. A limiting member connected to the connecting member is installed in the limiting hole. By adjusting the position of the limiting member in the limiting hole, the limiting rod 11 is driven to move outside or inside the open cavity 9, so that the U-shaped opening is connected to or disconnected from the card board 7. Specifically, the limiting member is a control screw 10. The limiting hole includes a smooth hole 18 communicated with the open cavity 9 and a threaded hole 17 communicated with the smooth hole 18. The internal thread of the threaded hole 17 matches the external thread of the control screw 10, and the length of the external thread of the control screw 10 is greater than the length of the internal thread of the threaded hole 17. The connecting member includes a collar 12 and two backing plates 14 respectively installed at both ends of the collar 12. The two backing plates 14 are a circular backing plate for closing the end of the collar 12 and an annular backing plate sleeved on the control screw 10 respectively, so as to limit the collar 12 from moving along the length direction of the smooth section (non-threaded section) of the control screw 10. The collar 12 can only rotate freely relative to the control screw 10. The connecting rod 13 is movably connected to the limiting rod 11 and the collar 12 through a rotating shaft 15 respectively, so that the connecting rod 13 can rotate freely between the end face of the limiting rod 11 and the side face of the collar 12. When the control screw 10 is rotated so that the control screw 10 moves outside the arc-shaped slider 8 along the limiting hole 18, the control screw 10 drives the collar 12 to move together, and the connecting rod 13 pulls the limiting rods 11 to move closer to each other, and the limiting rods 11 will retract into the open cavity 9; when the control screw 10 is rotated so that the control screw 10 moves inside the arc-shaped slider 8 along the limiting hole 18, the control screw 10 drives the collar 12 to move together, and the connecting rod 13 pushes the limiting rods 11 to move away from each other, and the limiting rods 11 will protrude outside the port of the open cavity 9. A trapezoidal empty groove 16 communicated with the open cavity 9 is provided on each side of the limiting hole. The thickness of the trapezoidal empty groove 16 is coordinated with the width of the connecting rod 13, which can meet the up and down movement of the connecting rod 13 with the up and down reciprocating movement of the collar 12. The arc-shaped slider 8 is composed of two symmetrical blocks connected and assembled by a bolt rod 19, which is convenient for freely replacing the components inside the arc-shaped slider 8.

[0035] Before placing the arc-shaped slider into the arc-shaped through groove, rotate the control screw 10 to completely retract the limiting rod 11 into the through cavity 9. Place the arc-shaped slider 8 into the card slot 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 U-shaped opening positions at both ends of the through cavity 9 are exactly aligned with the positions of the two clamping plates 7 in the card slot 6 on the insertion ring 4. Rotate the control screw 10 to make the limiting rod 11 move outward along the through cavity 9, so that the clamping plate 7 is inserted into the U-shaped opening of the limiting rod 11, and tighten the control screw 10. At this time, the control screw 10 is completely placed inside the arc-shaped slider 8. Drive the second connecting member 2 to rotate the insertion ring 4 thereon in the first annular groove of the first connecting member 1, so as to drive the arc-shaped slider 8 to rotate in 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 of the inner cavity of the first annular groove, thereby realizing the axial load transfer between the first connecting member 1 and the second connecting member 2 and enabling them to perform axial synchronous translation movement; since the arc-shaped slider 8 can rotate circumferentially in the second annular groove, it can simultaneously satisfy the circumferential rotation of the insertion ring 4 in 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.

[0036] This embodiment also has the following beneficial effects: simple operation 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 4 thereon in the first annular groove of the first connecting member 1, it drives the arc-shaped slider to rotate in the second annular groove of the first connecting member 1, enabling the first connecting member and the second connecting member to achieve non-coupled independent free rotation in the circumferential direction.

[0037] Although the above embodiments have described in detail the concept and implementation of the object of the present invention 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, so they will not be elaborated here one by one.
