Abstract

The utility model discloses a retaining clip, comprising a clamp, a C-shaped component, a screw, rubber bands and mounting pieces. The retaining clip is characterized in that a convex lug boss and a concave lug boss are arranged along the edge of a mounting hole on the back of the clamp and can be meshed mutually when the two pieces of the clamp are combined back to back; semicircular mounting grooves are respectively arranged at two sides of the mounting hole and inside the clamp, a hole is arranged in each mounting groove to communicate the inside of the clamp with the back of the clamp; ribs are arranged outside the rubber bands and corresponding to the holes in the mounting grooves of the clamp, and the ribs are cooperated with the holes in the mounting grooves of the clamp to fix the rubber bands in the mounting grooves of the clamp; press plates are arranged respectively at both sides of the whole set of clamp. The utility model has the advantages that when the retaining clip is assembled, the rubber bands in the clamp are ensured not to slide out of the clamp because of the carelessness of the operator, not to rotate due to clamping force and not to sink or be broken due to clamping force.

Description

A kind of geometrical clamp

Technical field

The utility model relates to moving communicating field, relates in particular to the fixedly anchor clamps of feeder line, optical cable or cable, i.e. geometrical clamp.

Background technology

In mobile base station, machine room, feeder line, optical cable or cable need come it is fixed with geometrical clamp.The structure of geometrical clamp commonly used is at present: as Fig. 1, on C type assembly, be fixed with a full silk screw rod, clip is through on the full silk screw rod, and geometrical clamp comes feeder line, optical cable or cable are fixed to the hole of fashionable formation or by the hole in the rubber ring of clamping in this hole by clip.As Fig. 2, clip in this structure is because its back side is a burnishing surface, make it mutual rotation can take place when fastening installing, can cause clip stressed place depression even breakage to clip when fastening with nut and plain cushion, rubber ring can be when installing and using comes off owing to operator's general idea causes.

Summary of the invention

The utility model is exactly in order to solve above shortcoming, provides a kind of clip that mutual rotation does not take place when mounted, and clip can not cause stressed place depression or damaged, the geometrical clamp that rubber ring also can not come off when installing and using when fastening.

A kind of geometrical clamp of the present utility model, comprise clip, C type assembly, full silk screw rod, rubber ring and installed part, full silk screw rod is fixed on the end face of C type assembly, clip is suitable in pairs on full silk screw rod, accompany rubber ring in the two involutory clips, it is characterized in that: the circumferential edge of the dorsal part installing hole of described clip can intermeshing concave-convex boss when being the opposing installation of two clips, be equipped with semicircle mounting groove at the inboard of clip and in the both sides of installing hole, being provided with the hole in the groove makes the inboard of clip communicate with dorsal part, hole opposite position in the outside of rubber ring and the clip mounting groove is provided with convex tendon, hole in this convex tendon and the clip mounting groove matches in the incompatible mounting groove that rubber ring is fixed on clip, and the both sides of whole group clip are respectively arranged with pressing plate.

Further, interference fit is adopted in the convex tendon and the hole in the clip mounting groove that are provided with of the described rubber ring back side.

Further, the convex tendon at the described rubber ring back side is provided with the projection greater than the hole in the clip mounting groove, and the earthing should projection be fixed on rubber ring in the mounting groove of clip.

Further, be pressed with boss with the fastening direction rightabout of pressing plate projection on the installing hole of the centre of described pressing plate.

Further, two parallel edges of described pressing plate have the flanging that cooperates with the clip profile phase along folding.

Further, the concave-convex boss on the described clip is to be formed by two spill platforms and being spaced of two convex platforms.

Further, the clamping hole of the inboard of described rubber ring is semicircle or half elliptic.

The dorsal part of the clip in the utility model can intermeshing concave-convex boss when the installing hole circumference is provided with two opposing installations of clip, and the concave-convex boss is meshing with each other and makes clip that mutual rotation not take place during installation.Be respectively arranged with a pressing plate in the both sides of whole group clip and make the clip lifting surface area increase greatly, depression even the breakage of having avoided the stressed place of clip to take place.Because rubber ring is fixed in the mounting groove of clip by the convex tendon at its back side, thereby cause coming off of rubber ring installing and using the general idea of Shi Buhui owing to the operator.

Embodiment

As shown in Figure 3, the utility model comprises clip 4, C type assembly 2, full silk screw rod 1, rubber ring 5, the structure of described C type assembly 2 is as follows: after special bolt 22 screws in nut 23, bullet pad 24 successively, screw in the C type spare opening from a side of C type spare 25, and the riveting of rising in the end that its special bolt 22 is positioned at C type spare opening installs bowl-type rubber pad sheet 26, and bowl-type rubber pad sheet 26 can freely rotate in the end of special bolt 22.Full silk screw rod 1 is fixed on the opposite side end face of C type assembly 2, and clip 4 is involutory in pairs to be through on the full silk screw rod 1, and two involutory clips accompany rubber ring 5 for 4 li.

As shown in Figure 4, be provided with installing holes 10 in the middle of the clip 4, along being designed to concave-convex boss 11, concave-convex boss 11 can be meshing with each other when making opposing installations of two clips 4, and clip 4 rotation mutually when fastened with the circumferential edge of the dorsal part installing hole 10 of clip.Identical, the complementary dimensioned of quantity of these concave-convex boss 11 camber platforms and spill platform, and be spaced, the quantity of convex platform and spill platform all 〉=1 is preferably 2.At the inboard of clip 4 and in the both sides of installing hole 10 semicircle mounting groove 12 is set respectively, the cable that its size and required folder are joined or the sheath external diameter of feeder line are complementary.Have hole 13 in the mounting groove 12 and make the inboard of clip 4 communicate with dorsal part, the optimum seeking site in hole 13 parallels with installing hole 10 in the centre and the direction of semicircle mounting groove 12, and this hole can be forms such as circle, square, triangle, ellipse, circular.Clip 4 is injection molded by engineering plastics such as polypropylene, ABS.

As shown in Figure 5, the semicircle mounting groove 12 of rubber ring 5 back sides and clip 4 is complementary, and the inboard of rubber ring 5 is provided with installing hole, and the cable that this installing hole and required folder are joined or the sheath external diameter of feeder line are complementary, and this installing hole can be semicircle or ellipse.Rubber ring 5 back sides are provided with convex tendon 20, the form in the hole 13 of being opened in the form of convex tendon 20 and the clip mounting groove 12 matches, convex tendon 20 matches with the hole 13 in the clip mounting groove 12 rubber ring 5 is fixed in the mounting groove 12 of clip, this cooperation can be interference fit, also the projection 21 bigger than 13 sizes of the hole in the clip can be set on convex tendon 20.Convex tendon 20 length with exceed clip 5-10mm after hole 13 in the clip cooperates and be advisable.After 13 employings of the hole in convex tendon 20 and the clip are tightly fixed, convex tendon 20 are exceeded clip partly cut off.When fixedly the rubber ring employing is provided with the projection 21 that the hole dimension in the semicircle mounting groove is big than clip on convex tendon 20, after rubber ring 5 fixes, should convex tendon 20 be cut off along protruding 21 outsides.
