The proposal has the advantages of simple structure and easy production.

Description

Fastener for connection

The utility model belongs to coupling components, is used for being connected and fixed of flexible ribbon object.

Parts are used in being fixedly connected of known connection flexible ribbon object such as belt, waistband etc., and through hole normally is set on belt body, are shaped on and can penetrate this hole, stop under tension belt body state the framework that belt body deviates from and the form of inserted link at the other end.This structure is easy to use, reliable, but belt body has weakened tensile strength own because of perforation, and its syndeton length also is subjected to the restriction of lead to the hole site.Another kind be flexible belt be tightened up can clamp under the state join the structure of belt body, this form has different modification, the position that the belt body of clamping enlarges, is connected and fixed than the position that perforation is connected is convenient to regulate, but connecting the position that is contacted still is confined within the scope of multiple spot or line, still be easy to cause the belt body local damage, thereby influence service life.

The purpose of this utility model is to provide the flexible ribbon object that a kind of form that is connected and fixed is more reasonable, service life is long to connect fastening structure.

The purpose of this utility model is to realize like this, still utilize the connection secure component of known clamping form, the basic structure that comprises framework, eccentric clamp assemblies, but with desire fixedly the belt body working surface of clamping up and down that contacts, rise clamping anastomosis parts be all the plane, be by cooperating, bear eccentricity pressure with eccentric part and becoming the movable tabular pressure-containing member that connects to constitute along the eccentricity pressure direction wherein with framework with the clamping working surface that eccentric part links.Like this, the hold assembly clamping by having the plane can reduce the local pressure to belt body, reduces the destructiveness to belt body itself; And the required pressure that is connected and fixed is to be provided by clamping area enough under the certain pressure, transmits the pressure-containing member that eccentricity pressure can form required clamping plane again like this, has the dual-use function of pressure transmission and plane clamping.This programme had both kept be connected and fixed whole advantages of mode of former clamping, has improved the clamping force-bearing situation of belt body again, thereby the purpose of this utility model is achieved.

Movable part in the utility model hold assembly and framework are resilient connection, and the direction of elastic force effect makes two clamping surfaces of clamp assemblies be state separately under non-coupled situation.This state helps that belt body enters between clamp assemblies two clamping surfaces, for use brings convenience when implement connecting.

The utility model clamping surface is made the surface that has concaveconvex structure, as groove or the point-like projection that distributes at grade, be used for increasing the by-local forces what of clamping, can under the situation that guarantees suitable grip strength, reduce the area of clamping surface, the overall dimensions of this structure is reduced, can not cause the destruction strong excessively simultaneously again belt body.

The stage shape that the edge has projection is made in the eccentricity pressure direction in the relevant position, pressure-containing member surface that the utility model matches with eccentric part, between eccentric part or pressure-containing member and framework in belt body clamping plane belt body length direction leave the gap, gap width should guarantee that eccentric part can produce eccentricity pressure at arbitrary ledge surface.So highly the step that does not wait can produce different eccentricity pressures, the boss at edge can prevent the slippage vertically of interactional surface, being set gap stays position in different step participation work to off-centre, the projection of step edge makes and cooperates reliably, thereby makes this structure determine suitable operating position according to the requirement of clamping thickness and pressure.

The utility model also is provided with the mechanism of the mutual alignment between the impaction state clamp assemblies of being connected and fixed, as various ways such as the collar, snap closes.

On the frame base of the present utility model around the relevant position be provided with riveted holes, and be provided with slotted hole in the edge of vertical flexibility band belt length direction.Two kinds of passes are convenient to the selection that implementation framework connects with the belt body different types.

The utility model has improved former flexible ribbon object and has connected fastening structure, the service life that can obviously improve the flexible ribbon thing.Scenario-frame is simple, easy to use, easy to implement.

Accompanying drawing is the utility model embodiment signal.

Fig. 1 is the overall structure signal;

Fig. 2 is the structural representation of clamping working face;

Fig. 3 is the latch-up structure signal;

Fig. 4 is a bearing plate assembly diagrammatic sketch.

This example is the hasp that is used for common waistband, waist-belt, is shaped on connecting hole 7,15 in order to realize being connected and fixed of riveted joint of this example and waistband one end or canoe on base plate 1; Also have and base plate limit all-in-one-piece support the off-centre 11 and the bearing plate axle 2 that are used for setting-up eccentricity axle 3 and link with axle in the base plate both sides; The off-centre 11 of band plate hand 9 and the bearing plate 6 that matches with eccentric surface match with separately bolster respectively; Spring 12 also is housed at bearing plate axle place to link bearing plate and base and eccentric elasticity by pressing plate 13.The belt body that allows desire to connect in opening between the lower surface of bearing plate and the base upper surface passes, but in working order down the belt body between clamping two surfaces realize that connection is fastening.

The other end with waistband during use inserts between the bearing plate of opening shape and base upper surface, the position connects hasp on request, plate descends eccentric 11 wrench 9 then, to press to the upper surface of hasp base by the bearing plate 6 that spring 12 is held open shape, tightly clamping of pressure after making belt body between bearing plate and base upper surface by eccentric rotary has realized being connected and fixed reliably.

Second embodiment is that the apparent surface at bearing plate and base all can be shaped on groove 14, increasing the average pressure of hasp to belt body, or reduces overall dimensions.

The 3rd embodiment is shaped on the stage 5 that does not highly wait on eccentric bearing plate surface with the bearing plate cooperation place, and step edge is shaped on projection 4.The eccentric connection with framework left end play, but gap width is controlled at the both sides that allowable offset is fixed on pressure-containing member upper surface step edge projection 4, to play the effect that this hasp compresses gap and thrust of regulating, make hasp be applicable to the waistband that thickness is different, maybe can adjust the clamping action power under the user mode.

The 4th embodiment installs plate washer 8 additional at the bearing plate upper surface, and the latch hook 10 that makes it to answer the position to be provided with the eccentric disk palmistry matches.When wrench 9 is in running order, rotate latch hook 10, make it to block with plate washer 8 lower surfaces, play the effect of fixing eccentric circumferential position, be used for preventing eccentric because the situation that tightening state is destroyed that connects is caused in the accidental change position.

The framework clothing plate of the 5th embodiment is provided with two kinds of connection holes, and a kind of is riveted holes 15, is located at four jiaos of base plate; Another kind is that long slot bore 7 is located at and the parallel bottom edge of eccentric shaft 3 bearing plate axles 2.It can provide this hasp the connecting mode different with belt body to the user, enlarges the scope of application and the form of this hasp, and all the other structures can be with any of above example or its combination, and it is multiple functional to form this programme, the service-strong preferred example.
