Abstract

The utility model relates to a clamping fastener. The utility model has firm fastening, good using performance and beautiful shape. The utility model is composed of a holder and a fixing sleeve. The two ends of the holder are separately provided with a frame body and a cover body, the one relative side of the frame body is extended to form two slice bodies which are linked with the cover body, and a setting channel linked with the through hole of the frame body is formed. The other relative side of the frame body is symmetrically extended to form two elastomers which are in camber angle. The fixing sleeve is a hollow sleeve body provided with a through hole. The distance between the inner walls of the corresponding side of the two elastomers on the holder is smaller than the distance between the outer sides of the two elastomers. The through hole of the fixing sleeve is corresponding to the periphery of the frame body of the holder.

Description

Clamping fastening device

The utility model belongs to fastener, particularly a kind of Clamping fastening device.

The slider of zipper fastener sheet of slide fastener on briefcase, travelling bag and the gym suit now, the extension rope that is provided with on it adopt usually as shown in Figure 8 be the Clamping fastening device of conical woodwork.Clamping fastening device is provided with central through hole.During use, rope ends must be penetrated in the central through hole of Clamping fastening device, and make a call to a knot, in case anti-avulsion goes out as backstop.This Clamping fastening device of commonly using in use, defective such as not only knot very easily gets loose on it, Clamping fastening device moves forward and backward and can't locate, and its outward appearance utmost point is not attractive in appearance.

The purpose of this utility model provides that a kind of clamping is firm, serviceability good, the Clamping fastening device of good looking appearance.

The utility model is made up of holder and fixed cover, one end of holder is a framework, its other end is a lid, the framework opposite side extends two lamellar bodies and is connected with lid, and the holding channel that is connected with through hole on the framework of formation, another opposite side symmetry of framework extends two elastomers that are camber angle, and the elastomer inside end is provided with engaging piece, and makes the length of elastomeric length less than holding channel; Fixed cover is the hollow sleeve that is provided with through hole, its with holder on the inwall spacing of the corresponding side of two elastomers less than the spacing between the two elastomers outsides, through hole is corresponding with the periphery of holder upper frame body on it; Holder pushes in the fixed cover with its framework end, is positioned at the through hole of fixed cover until framework, and compresses two elastomers with the inwall of fixed cover to the center.

Wherein:

The inboard of holder lid is provided with the male half coupling that only can block at the fixed cover opening part.

The holder framework outside relatively is arranged with grab; Be provided with in week in the fixed cover through hole with framework on the grab slot of buckle mutually.

Elastomeric engaging piece is the prism that is provided with grinding tooth.

Elastomeric engaging piece is the cylinder that is provided with grinding tooth.

Because the utility model is made up of holder and fixed cover, the two ends of holder are respectively framework and lid, the framework opposite side extends two lamellar bodies and is connected with lid, and the holding channel that is connected with through hole on the framework of formation, another opposite side symmetry of framework extends two elastomers that are camber angle, fixed cover is the hollow sleeve that is provided with through hole, its with holder on the inwall spacing of the corresponding side of two elastomers less than the spacing between the two elastomers outsides, through hole is corresponding with the periphery of holder upper frame body on it.During assembling, penetrate on fixed cover through hole and the holder framework through hole successively and be positioned at the holder holding channel with the two ends of the rope that passes slider of zipper fastener, holder is pushed in the fixed cover with its framework end, be positioned at the through hole of fixed cover until framework, and compress two elastomers to the center, make tightly interlock rope of two elastomeric engaging pieces with the inwall of fixed cover, rope is gripped, not only clamping is firm, serviceability is good, and good looking appearance, thereby reaches the purpose of this utility model.

Below in conjunction with accompanying drawing the utility model is further elaborated.

As shown in Figure 1 and Figure 2, the utility model is made up of holder 1 and fixed cover 2.One end of holder 1 is a framework 11, and its other end is a lid 12.Framework 11 outside relatively is arranged with grab 111.Framework 11 opposite sides extend two lamellar bodies 13 and are connected with lid 12, and the holding channel 131 that is connected with through hole 112 on the framework 11 of formation.Another opposite side symmetry of framework 11 extends two elastomers 14 that are camber angle, and makes the length of the length of elastomer 14 less than holding channel 131.Elastomer 14 inside end are provided with the engaging piece 141 of indentation.Engaging piece 141 is for being provided with the prism of grinding tooth; Also can be the cylinder that is provided with grinding tooth.The inboard of lid 12 is provided with male half coupling 121.Fixed cover 2 is for being provided with the hollow sleeve of through hole 21, its with holder 1 on the inwall spacing of two elastomers, 14 corresponding sides less than the spacing between two elastomers, 14 outsides, through hole 21 is corresponding with the periphery of holder 1 upper frame body 11 on it, and in through hole 21 places, be provided with in week with framework 11 on grab 111 slot 211 of buckle mutually.

During assembling, as shown in Figure 3, Figure 4, pass slider of zipper fastener sheet 4, penetrate through hole 112 on the through hole 21 of fixed cover 2 and holder 1 framework 11 successively with the two ends 31 of rope 3 again and be positioned at the holding channel 131 of holder 1 with rope 3.As Fig. 5, shown in Figure 6, holder 1 is pushed in the fixed cover 2 with its framework 11 ends, male half coupling 121 cards that are positioned at through hole 21 places of fixed cover 2 and lid 12 until framework 11 end at fixed cover 2 opening parts, and compress two elastomers 14 to the center with the inwall of fixed cover 2, the engaging piece 141 that makes two elastomers 14 is interlock rope 3 tightly, and rope 3 is gripped.As shown in Figure 7, when rope 3 was subjected to the external force tractive, the engaging piece 141 of two relative elastomers 14 promptly produced an inside chucking power, makes two elastomers 14 relatively inwardly rotate minute angle, formed the reaction force of opposing counter-force, and rope 3 is clamped further.
