Description

Mechanical fastener

Technical field

The utility model is related to a kind of mechanical fasteners.

Background technology

Currently, in various mechanical equipments, the use of mechanical connecting parts is very extensive.The shape of these mechanical connecting parts Shape, structure also there are many kinds of, the harness in mechanical equipment can pass through the inside cabling of mechanical connecting parts.Due to the harness being related to Can be very much, so need wire rod will all be arranged together, it in this way can be by plugging line winder, by all lines in maintenance Material is extracted or is inserted into out of mechanical equipment.But line winder is using based on metal plate at present, its moulding process is multiple first Miscellaneous, secondly metal plate is one-pass molding, cannot be adjusted during use, insufficient for the adaptability of harness, is needed The line winder constantly more renewed, production cost is higher, causes prodigious waste.

Utility model content

The purpose of this utility model is to provide a kind of mechanical fastener that can be adjusted according to different cablings.

In order to solve the above technical problems, the utility model mechanical fastener, including：Shell, the shell are hollow structure； Connecting shaft hole, the connecting shaft hole are arranged in one end of the shell；Connecting pole, the connecting pole are set around the connecting shaft hole It sets；The other end in the shell is arranged in mounting hole, the mounting hole；Alignment apartment, the alignment apartment are arranged in the shell In vivo；The wherein described alignment apartment includes：Block is fettered, constraint hole is equipped on the constraint block；Shaft, the shaft setting exist The both ends of the constraint block；Connected unit, two connected units are rotatably connected on the both ends of the constraint block by shaft, in institute It states connected unit and is equipped with link slot and connecting hole.

Preferably, it is equipped with torsional spring in the outer sheath of the shaft.

Preferably, boss is equipped in the constraint hole, the boss is arranged on the inner wall in the constraint hole.

Preferably, it is equipped with crimp in the constraint hole, card slot, the boss card are equipped in the outside of the crimp It is connected in the card slot.

Preferably, the crimp includes fettering ring and around the snap ring for being located at the constraint ring both ends, the snap ring it Between gap be the card slot.

Preferably, it is equipped with annular groove between the snap ring and the inner wall in the constraint hole.

Preferably, the constraint block includes constraint seat and constraint lid, and the constraint lid is clamped with the constraint seat.

Preferably, the crimp is elastic material.

Compared with prior art, the connection in connected unit that the alignment apartment of the utility model mechanical fastener passes through both ends Slot and connecting hole are easily installed in body, and intermediate constraint block can be rotated around shaft, be suitable for different cablings Direction, and crimp can be in certain model in the case where the quantity of harness changes using its flexible performance It is adjusted in enclosing, certain restriction effect can be played to the trend of harness by being set in the torsional spring on the outside of shaft.Due to snap ring with There is gap between the inner wall in constraint hole, thus forms an annular groove for surrounding crimp, the test that can will be extracted from harness Line is positioned in annular groove, when needing to being detected across the harness in constraint hole, can be taken out p-wire from annular groove .The constraint seat and constraint lid of clamping constitute constraint block itself, can open constraint lid, are replaced to crimp.Meanwhile The material of rubber can protect the harness in it.In addition, alignment apartment itself uses carbon fiber, it can be in the feelings for mitigating weight Proof strength is unaffected under condition.

Description of the drawings

Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other spies of the utility model Sign objects and advantages will become more apparent upon.

Specific implementation mode

The utility model is described in further detail below, it is described to be the explanation to the utility model rather than limit It is fixed.The utility model is made further instructions below in conjunction with attached drawing.

As shown in Figure 1 and Figure 2, the utility model mechanical fastener, including：Hollow shell 11 is set in one end of shell 11 Connecting shaft hole 12, connecting pole 13 are arranged around connecting shaft hole 12, and mounting hole 14 is arranged the other end in shell 11, is respectively used to Connect mechanical arm and robot.

Alignment apartment is mounted in shell 11, including：Block is fettered, the constraint hole 2 of kidney-shaped, crimp are equipped on constraint block Itself include that constraint ring 7 and the gap between the snap ring 8 for being located at 7 both ends of constraint ring, the snap ring 8 of upper/lower terminal form card Slot (not shown).3 ring of boss is located on the inner wall in constraint hole 2, and the boss 3 of protrusion stretches into card slot (not shown), real The fixation of existing crimp 7 and constraint hole 2.

Due to having gap between snap ring 8 and the inner wall in constraint hole 2, an annular groove 9 around crimp is thus formed, Can will be positioned in annular groove 9 from the p-wire extracted in harness, when need to across constraint hole 2 harness be detected when It waits, can take out p-wire from annular groove 9, you can be detected.

Meanwhile the constraint seat 10 of clamping and constraint lid 1 constitute constraint block itself, can by constraint lid 1 open, to crimp into Row is replaced.

The connected unit 4 at constraint block both ends is rotatably connected on constraint block by shaft, and link slot is respectively equipped in connected unit 4 5 and connecting hole 6, certain restriction effect can be played to the trend of harness by being set in the torsional spring on the outside of shaft.

The link slot 5 and connecting hole 6 that the utility model alignment apartment passes through both ends in connected unit 4 can be installed easily In body, intermediate constraint block can be rotated around shaft, be suitable for different direction of routing, and crimp can utilize its tool Flexible performance can be adjusted in a certain range in the case where the quantity of harness changes.Meanwhile rubber Material can protect the harness in it.In addition, alignment apartment itself uses carbon fiber, can be protected in the case where mitigating weight It is unaffected to demonstrate,prove intensity.

Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office It is limited to above-mentioned particular implementation, those skilled in the art can make a variety of changes or change within the scope of the claims, This has no effect on the substantive content of the utility model.In the absence of conflict, the spy in embodiments herein and embodiment Sign can be arbitrarily combined with each other.
