To complete the construction or assembly, suitable connection means are required to connect and fasten the strip members.
In the prior art, many technical solutions for fastening connection have been proposed. For example, welding, fastening, bundling, screw fastening, hoop fixing, etc., but at present, no connection mode can simultaneously meet the requirements of convenient and quick disassembly, reusability and application to different types of members.

The object of the present invention is to provide a connection device and a connection method for fastening strip-like members.
For this purpose, the invention adopts the following technical scheme: the connecting device for fastening the strip-shaped member comprises the strip-shaped member and a connecting device, wherein the strip-shaped member is provided with a cylindrical connecting end; the method is characterized in that:
the device also comprises a base end and a fixed end, wherein the base end is provided with external threads, and the fixed end is provided with internal threads and can be meshed with each other; the base end and the fixed end are hollow, and the inner diameter of the base end and the fixed end is larger than the outer diameter of the strip-shaped member so as to enable the strip-shaped member to penetrate through the base end and the fixed end;
the clamping ring is in a partial ring shape with a fracture in the circumferential direction, and the circumference of the clamping ring is not less than 2/3 of the whole circumference; the clamping ring is sleeved outside the strip-shaped member, forms clearance fit with the strip-shaped member and can slide along the axial direction of the strip-shaped member; the inner wall of the clamping ring is a broken cylindrical surface, the outer wall is a broken circular table surface, namely the thickness of the lower end of the clamping ring is larger than that of the upper end of the clamping ring;
the thickness of the lower end annular wall of the clamping ring is larger than the gap between the inner wall of the base end and the strip-shaped member and smaller than the distance between the outer wall of the base end and the strip-shaped member, the clamping ring is sleeved outside the strip-shaped member, the strip-shaped member extends into the base end, and the lower end of the clamping ring is abutted against the base end;
the lower part of the inner wall of the fixed end is provided with an internal thread, the upper part of the inner wall is provided with an inward protruding step surface, and the inner diameter of the step surface is larger than the sum of the outer diameter of the strip-shaped component and the thickness of the upper end ring wall of the clamping ring and smaller than the sum of the outer diameter of the strip-shaped component and the thickness of the lower end ring wall of the clamping ring.
When the clamping ring is used, the clamping ring is sleeved outside the strip-shaped member, and then the fixed end is sleeved outside the clamping ring, so that the clamping ring can slide on the strip-shaped member; the connecting end of the strip-shaped component extends into the base end, so that the lower end of the clamping ring is abutted against the base end, and the clamping ring cannot fall into the base end or influence the threaded engagement of the base end and the fixed end due to the specific thickness limitation of the lower end wall of the clamping ring; then gradually screw up the stiff end, along with the internal and external screw engagement degree is bigger and bigger, the stiff end moves downwards and bigger for the base end, and the step face of stiff end inner wall moves downwards outside the snap ring, tightens up the snap ring gradually in this process for the snap ring inwards contracts, hugs tightly the strip component, thereby reaches the purpose of connection, fastening.
The invention can also adopt the following further technical scheme:
the base ends are integrally formed to form a part.
The inner cavity of the base end is provided with a limit boss, and a gap formed by the limit boss is smaller than the outer diameter of the strip-shaped component.
The inner wall of the clamping ring is a rough surface; the fracture of the clamping ring is a bevel from top right to bottom left; the snap ring is provided with a plurality of grooves in the height direction, and the directions of the adjacent grooves are opposite; the circumference of the clamping ring is not less than 5/6 of the circumference.
The step surface of the inner wall of the fixed end is a step inclined surface, and the slope of the step surface is consistent with that of the outer wall of the clamping ring. In this case, the inner diameter of the step slope satisfies all of the geometric conditions described above, i.e., the inner diameter of any one height of the step slope is larger than the sum of the outer diameter of the strip member and the thickness of the upper end wall of the retainer ring and smaller than the sum of the outer diameter of the strip member and the thickness of the lower end wall of the retainer ring.
The other technical scheme adopted by the invention is as follows: the connecting method for fastening the strip-shaped members adopts the connecting device and comprises the following steps: sleeving the fixed end outside the connecting end of the strip-shaped member, sleeving the clamping ring outside the connecting end of the strip-shaped member, and enabling the clamping ring to slide along the axial direction of the strip-shaped member so as to adjust the position of the clamping ring on the connecting end; inserting the connecting end into the base end to enable the lower end of the clamping ring to be abutted against the port of the base; keeping the relative position of the strip-shaped component and the base end unchanged, and simultaneously screwing the fixed end; the clamping ring deforms in the process of tightening the fixed end, and the connecting end is held tightly, so that the strip-shaped component is fastened.
The strip-shaped member of the present invention may be a standard cylindrical shape such as a metal pipe, a processed rod, etc., or a member having a substantially circumferential surface such as natural wood, bamboo, or a rope, etc., which is extruded to have a cross section close to a circumference. Obviously, the closer the connecting end of the strip-like member is to the standard circumference, the better the fastening effect.
360 full circumference 0 The invention employs a broken partial ring, i.e. the ring is less than 360 0 But not less than 2/3 of a circumference, i.e. not less than 240 0 The clamping ring has quite large elasticity in the circumferential direction, and has certain redundancy to match with strip-shaped components with different outer diameters or less regularity; the rough inner surface of the snap ring helps to hold the strip-shaped member, the oblique fracture and the groove on the annular wall, so that the snap ring can be held or released in the thread direction better. After the limiting boss is arranged in the base end, the movement of the strip-shaped member into the base can be limited under extreme conditions; the multiple bases are integrally formed, and a specific angle can be designed according to the building requirement, so that the condition that the rod piece is required to be connected in a complex geometry is particularly facilitated; under the condition of adopting the step inclined plane, the inclined plane is contacted with the round table surface of the outer wall of the clamping ring, the contact surface is larger, the pressure applied to the clamping ring through the fixed end is also larger, and the clamping ring can have better fastening effect.
When the fixed end is screwed up, the step surface or the step inclined surface of the fixed end gives continuous circumferential pressure to the clamping ring, and the clamping ring is subjected to radial and axial pressure simultaneously through an orthogonal decomposition method, so that deformation is generated, and the strip-shaped component is fastened.
Another advantage of the present invention is that the length of the bar-like member extending into the base end does not have a precise requirement, and the position of the snap ring on the bar-like member can be adjusted to find an appropriate fastening position and then tighten the fixed end when the fixed end is not yet tightened. The adjustable fixing mode enables a user to freely adjust the length of the strip-shaped member left outside to a certain extent, and is more beneficial to the firmness and the attractiveness of the whole construction.
From the analysis, the invention has the advantages that the invention is suitable for various different use environments and different component types, and the component itself does not need to be processed and modified; the meshing force of the threaded connection is converted into the cohesion force to the component, so that the fastening effect is good; the installation and the disassembly are convenient, and the device can be repeatedly used for many times; the snap ring used as a wearing part is very cheap and has extremely low use cost.
