no. 1 Embodiment

[0048] figure 1 Indicates the general assembly structure of the locking device. The locking device is composed of a fixing bolt 101 , a clamping sleeve 102 and a locking cap 103 . The clamping sleeve 102 has a tapered structure and is located inside the locking cap 103; the locking cap 103 is located at the upper end of the fixing bolt 101, and the two are locked with each other through internal and external threads; the locked filament 104 runs through the entire locking device along the central axis.

[0049] FIG. 2( a ) shows the internal structure of the fixing bolt 101 . The fixing bolt 101 mainly includes two parts: a bolt shaft 201 and a bolt cap 202 , wherein the bolt shaft 201 includes a lower through hole 203 inside, the lower through hole is a circular through hole, and the lower through hole runs through the entire bolt shaft 201 .

[0050] The length of the bolt cap 202 is slightly longer than the bolt shaft 302 of the locking cap 103 . Bolt cap 202 inside comp...

no. 2 Embodiment

[0066] On the basis of the first embodiment, by increasing the number of thread clamping holes and rectangular grooves of the clamping sleeve, two non-adjacent filaments or three non-adjacent filaments can be locked at the same time.

[0067] Figure 5(a) shows the internal structure of the clamping sleeve for clamping two non-adjacent filaments. The clamping sleeve 501 is in the shape of a truncated cone, and its material is spring steel. The filament clamping holes 504 are symmetrically located on both sides of the center of the clamping sleeve 501, and the filament clamping holes 504 are two circular through holes with equal diameters, and the two circular through holes pass through the entire clamping sleeve 501. And vertically penetrate the lower bottom surface 502 and the upper bottom surface 503 , the two circular through holes are separated from each other by a certain distance.

no. 3 Embodiment

[0079] On the basis of the first embodiment, by increasing the number of thread clamping holes and rectangular slots of the clamping sleeve, two filaments with tangential outer diameters or three filaments with tangential outer diameters can be locked at the same time.

[0080] Figure 7(a) shows the internal structure of the clamping sleeve used to clamp two filaments with tangential outer diameters. The clamping sleeve 701 is in the shape of a truncated cone, and its material is spring steel. The filament clamping hole 704 is two circular through holes with tangential outer diameters, the two circular through holes are tangent to the central axis of the clamping sleeve 701, and the diameters of the two circular through holes are the same, so The above two circular through holes both vertically penetrate the lower bottom surface 702 and the upper bottom surface 703 .

Abstract

The invention discloses a locking method of a filament and the device, aiming at providing the filament locking method and the mechanical device which can be disassembled and repeatedly used and can provide large locking force after being screwed. The key point of the technical proposal is that the device consists of a fixed bolt, a clamping sleeve and a locking cap. The clamping sleeve is arranged inside the locking cap which is arranged at the upper end of the fixed bolt. The fixed bolt and the locking cap are mutually locked by an internal thread and an external thread. The locked filament passes through the central axis line of the locking device; the fixed bolt is used for containing the locking cap and the clamping sleeve and fixing the whole device. The clamping sleeve guides and clamps the filament; the fixed bolt, the clamping sleeve and the locking cap are matched with each other so as to lock the filament. By rotating the locking cap, the mutual action of the force is formed between the filament and each part of the locking device, thus realizing the locking of the filament. The locking method generates large locking force, can lock wire material with various diameters, not only can lock a single filament, but also can lock a plurality of filaments at the same time. The locking device has simple structure, convenient installation, easy processing and manufacture, easy disassembly and repeated application.

Description

technical field [0001] The invention relates to a fastening mechanical device, in particular to a detachable filament locking method and a mechanical device with threads and tapered sleeves capable of providing large locking force after tightening. Background technique [0002] At present, the locking methods of filaments mainly include winding method and top wire method. The winding method is to wind the filament on a fixed object, tie the filament into a knot, adjust the tightness of the knot, change the locking force, and realize the fastening of the filament. The locking force generated by the locking method mainly depends on the tightness of the knot. The tighter the knot, the greater the locking force. Therefore, it is difficult to obtain a larger lock for the rigid filament because it is not easy to produce a large twist. and easy to fall off; the locking method is cumbersome to operate, and the locking force is affected by human factors. [0003] The jackscrew meth...
