Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.

The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and examples.

The utility model provides a bolt sub-assembly, it includes bolt 7 and the nut 4 that matches with this bolt to and the bottom surface centre gripping is fixed in cylindric sheath 1 between bolt 7 and the nut 4.

The opening of the cylindrical sheath 1 is upward, the bottom surface of the cylindrical sheath is arranged between the bolt 7 and the nut 4, the head of the bolt 7 is surrounded by the side wall, the height of the head of the bolt 7 is higher than that of the head of the bolt 7, the part above the head of the side wall of the cylindrical sheath 1 is provided with at least two through holes 3, when cables are wired, the cables can be wired through the through holes 3 on the side wall of the sheath 1, penetrate through the first through holes and penetrate through the second through holes.

Wherein, the shape of sheath 1 is cylindrical, and it can better match with the head of bolt 7.

The bottom surface of the cylindrical sheath 1 is provided with the through hole 2, the size of the through hole 2 is between the rod part and the head part of the bolt 7, when the cylindrical sheath is installed, the rod part of the bolt 7 can penetrate through the through hole 2 on the bottom surface of the cylindrical sheath, the size of the through hole 2 on the bottom surface is between the rod part and the head part of the bolt 7, so that the bolt cannot penetrate through the head part after penetrating through the rod part, and at the moment, after the nut 4 is added, the sheath can be limited between the head part of the bolt 7 and the nut 4, so that the fixing effect is achieved.

Referring to fig. 1 and 2, the side wall 1 of the sheath is provided with through holes 3, in this embodiment, the through holes 3 are rectangular and uniformly arranged along the side wall of the cylindrical sheath 1, and when the cable is routed, the cable passes through the through holes 3 on the side wall 1 and then passes through another through hole 3 on the side wall, so as to route the cable. Wherein, after passing through the perforation 3, in order to ensure the stability of the cable fixation, the cable and the sheath can be bound together by the wire turns, thereby realizing the fixation between the wire sheath 1 and the cable.

Specifically, the height of sheath 1 is 20mm in this embodiment, and perforation 3 is installed in 6mm department from sheath 1 bottom surface, and its perforation height is 10mm, and the width is 4mm, and the diameter of the circular through-hole 2 in sheath 1 bottom surface is 5mm, and the inner wall diameter of sheath 1 is 14mm, and the external diameter is 16mm, and its specific size can be adjusted according to actual demand.

The shape of perforation 3 still can set up to circular, its size need satisfy the cable threading can, it sets up at least two, even distribution is on 1 lateral wall of sheath, when the cable threading, can follow a circular perforation 3 and get into to wear out from another circular perforation 3, realize walking the effect of line through sheath 1.

The nut 4 in the bolt assembly is a riveting nut, and compared with a common nut, the riveting nut does not need to be provided with an internal nut, does not need to be welded, and is high in riveting fixing efficiency and convenient to use. When splicing, the riveting can be realized by using a pneumatic and manual hand riveter at one time, and the riveting is convenient and firm. The traditional welding nut is replaced, and the defects that a metal sheet, a thin pipe is easy to melt in welding, the welding nut is unsmooth and the like are overcome.

The bolt sub-assembly is still including locating the first panel beating 5 of riveting nut below and locating the second panel beating 6 between riveting nut 4 and bolt 7, and first panel beating 5 and the cooperation of second panel beating 6 are riveted nut 4 and are used, common fixed bolt 7.

The cylindrical sheath 1 is made of PP material, and the bolt assembly is not generally used as a main stress fastener, so that the mechanical property requirement of the sheath 1 is not high, the PP material can be used, and the bending fatigue resistance and the corrosion resistance of the PP material are good. In other use occasions, the rubber or plastic material can be selected according to actual conditions.

The utility model discloses an installation mode does: after selecting bolt 7 and nut 4 according to actual need, with the head of the opening direction orientation bolt 7 of sheath 1 to pass sheath 1 with the pole portion of bolt 7, then assemble second panel beating 6, riveting nut 4 and first panel beating 5 in proper order, wherein first panel beating 5 and riveting nut 4 are integrated into one piece, and it sets up in the below of riveting nut 4.

The utility model discloses the best scene of being suitable for is the electric cabinet of the difficulty of arranging of very compact, cable of structure, can effectively avoid the wearing and tearing problem that the cable takes place when long-term collision bolt.

After the installation is accomplished, because the bottom surface of sheath 1 is installed between the head of bolt 7 and second panel beating 6, the second panel beating 6 is compressed tightly by nut 4 again simultaneously to make sheath 1 fasten between the head of bolt 7 and second panel beating 6, when carrying out the cable wiring, can not take place to loosen the scheduling problem because sheath 1 is fixed not tight. Meanwhile, different from the prior art, the pressing surface of the head of the bolt 7 is the bottom surface of the sheath 1, so that the fixing effect can be further realized.

The utility model discloses an outstanding characteristics mainly lie in having set up sheath 1, walk the line through sheath 1, have solved the cable and have walked the wearing and tearing problem that line and bolt 7 collision took place, simultaneously, bolt 7 and nut 4's kind can change according to actual need. The utility model discloses well bolt 7 and nut 4 all adopt the standard component, so this bolt sub-assembly can realize standardization, reduce cost easily.

Compared with the prior art, the utility model discloses can walk the line through perforation 3 on the 1 lateral wall of sheath, avoid the secant that cable and bolt 7 take place to grind the line scheduling problem, simultaneously, can reduce the cable and walk the line point of solidus of line in-process, can directly fix with the turn on sheath 1, need not avoid the bolt 7 to walk the line carelessly, saved route and cable cost.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
