Description

Plastic buckle

Technical field

The utility model relates to technical field of fastening, especially relates to a kind of plastic buckle.

Background technique

In industrial products, two workpiece or plural object often need by riveted joint, screw thread, card and etc. form link into an integrated entity, and rivet, bolt generally all are fabricated metalss, can not use or be not suitable for to use in some occasion, must replace with nonmetallic material, so this continuously connected fastener just arises at the historic moment, continuously connected fastener kind of the prior art is also abundanter, but designing requirement all is to decide by its concrete function, and considers the characteristic that plastic materials has, and its characteristics are respectively arranged.As the patent No. is the coupling member of ZL200320131536.4 plastics inside gadget and car body stamping holes, this plastic buckle, be characterised in that on the inserting column of plastic buckle processing is provided with one and clamps ring, clamping ring is integrated with plastic buckle, the end cap of plastic buckle and clamp between the ring and to form an interlayer, its effect is when connecting plastics inside gadget and car body panel beating, and the interlayer of upper end connects the plastics inside gadget, and the inserting column of lower end connects the car body stamping holes.And for example the patent No. is 200420085680.3 1 kinds of nails, comprise a nail body, one end of nail body forms a sharp-pointed portion, the other end forms a head, nail body appropriate location is provided with the screw section of one section suitable length, is provided with a drive portion above the head of nail, and the screw section is to form the screw section in the both sides of nail body, wherein the position of screw section is with the head near the nail body, and this technology provides a kind of steel nail of conveniently pulling out.

Summary of the invention

The purpose of this utility model is to adopt being connected and fixed of plastic materials making to follow closely insufficient strength, the caducous problem in difficult location in order to solve, a kind of reasonable in design is provided, adopt the fin opposite to come off down in working order on the clasp nail body, and be provided with the plastic buckle of location with platform and gusset to prevent the clasp nail body with the sharp direction of nail.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of plastic buckle, comprise clasp nail, clamp lid, it is characterized in that described clasp nail is provided with a butt end, the other end is established a point, two sides are provided with some fins about the clasp nail body between butt end, the point, fin tilts towards butt end, is provided with some places platform in former and later two sides of clasp nail body, and butt end is provided with gusset towards a side of point.Clamp lid and fin all have certain elasticity, and after the clasp nail body entered the object that is fixed, fin flicked and clasp nail can not fallen back come off, and under the elastic force effect of clamp lid firmly.

As preferably, described some fins be arranged in parallel, and fin and clasp nail body are integral, and the tail end thickness of fin is less than the thickness at fin and clasp nail body connecting end place.The fin of thickness size had both had better elastic, had good intensity again, and the boring ratio clasp nail scapus body slightly larger in diameter on the internal fixation plate can not fall back clasp nail after some fin launches in internal fixation plate.

As preferably, described gusset is arranged by cross-shaped symmetrical, and the height of gusset is less than dunnage thickness.Gusset across or become three, six even distributed architectures, the through hole interference fit that the external diameter of gusset and dunnage are provided with as long as the height of gusset can be to the clasp nail axially locating, but is less than dunnage thickness, in order to avoid the clamp lid is produced roof pressure.

As preferably, described butt end end face is arranged with cross recess to clasp nail entity point direction.Cross recess is used for supporting the location compaction tool as drive portion.

As preferably, described point is the termination with circular arc.The position, termination is a tip but not sharp, helps safe assembling.

As preferably, described clamp lid is the round and elastic body of bell mouth shape in two ends up and down for the middle part is provided with reducing, and clamp lid axial centre is provided with through hole, the width between the fin outboard end that the diameter of through hole is provided with less than clasp nail body both sides.The clamp of same employing plastic production covers its horn mouth and has elasticity preferably, and when clasp nail is tightened to working position, its horn mouth is unfolded with dunnage or internal fixation plate and develops, when clasp nail passes the through hole that clamp lid axial centre is provided with, the both sides fin slightly shrinks just and can pass through, but passes through afterwards oppositely by check.

As preferably, the height of horn mouth one end at described clamp lid reducing two ends is big, and the other end height is little, and the horn mouth back side of a highly little end is provided with stiffening rib, and cuts edge vertically at two horn mouth diameter symmetry, two places.During installation, have the dunnage direction of an end of stiffening rib towards the outside, the asymmetry structure that does not highly wait makes clamp lid elasticity better, is difficult for impaired.

Effective effect of the present utility model is: the location and installation guiding utilizes Phillips screwdriver just can easily assemble easily, because the design of barb formula fin tightly interlocks the object more than two or two that is fixed, buckle can not come off.

Therefore, the utility model is a kind of reasonable in design, and is practical, convenient, fastening stable, the plastic buckle that overall cost is low in location.
