Abstract
The utility model discloses a fastener, which comprises a hooking head, a fastening piece and a hanging ring. The hooking head comprises a hook-shaped part on the upper part of the hooking head and a cylindrical connecting part on the lower part of the hooking head; the fastening piece and the hanging ring are sleeved on the cylindrical connecting part in turn; one side positioned at a hook-shaped opening of the hook-shaped part on the upper end face of the fastening piece is provided with a bulge which extends upwards and is matched with the opening of the hook-shaped part; a hole in an inner cavity of the fastening piece is a shoulder hole; an elastic component is sleeved between the fastening piece and the cylindrical connecting part of the hooking head; one end of the elastic component is supported on a step surface of the inner cavity of the fastening piece, while the other end is supported on supporting seat; a certain movable space is between the fastening piece and the hanging ring; and the end of the cylindrical connecting part of the hooking head exposed outside the hanging ring is provided with a positioning piece. The fastener has the advantages that: by changing the mode of the relative motion between the hooking head and the fastening piece in the fastener, the defects that a matching part of the conventional hooking head matched with the fastening piece has thin wall thickness and the tensile strength is low are changed; and the fastener has the advantages of very compact and beautiful structure and convenient operation.
Description
Technical field
The utility model relates to hardware, particularly a kind of fastener.
Background technology
Having many uses of fastener is able to extensively a large amount of employing on case and bag, key chain etc.Existing fastener, its structure is made of following several parts usually: comprise that gib head, fastener, hanging ring three parts constitute, the bottom of gib head is hung with hanging ring, in the groove of the described fastener bottom that is articulated in gib head as shown in Figure 1, the rotating shaft of fastener is provided with torsion spring, by pushing fastener, making fastener center on rotating shaft turns an angle, thereby the realization gib head separates with fastener, and when loosening fastener, fastener is return under the effect of torsion spring then.The shortcoming of this fastener is, because fastener is embedded in the gib head, the gib head of this part only is made of two of front and back, and therefore intensity herein is restricted, and can't bear bigger pulling force is weight, in order to subtract the possible volume that reduces fastener, and hook other object easily for the exposed junction that prevents fastener is long, therefore often the exposed junction of fastener is all shorter, and is relatively more difficult when this has just caused pushing, especially for the gay, use more inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of force intensity that is subjected to that improves fastener is provided, and the convenient fastener that uses.
A kind of fastener, comprise gib head, fastener, hanging ring, its structural feature is: described gib head comprises the crook on top and the column connecting portion of bottom, described fastener, hanging ring is set on the column connecting portion of gib head bottom, described hanging ring is positioned at the bottom of fastener, that side that is positioned at the crook hook openings in the fastener upper surface is provided with the projection that extends upward and match with the crook opening, the hole of fastener inner chamber is a shoulder hole, the upper end hole diameter of close crook is less than the diameter of lower end, between fastener and gib head column connecting portion, be set with elastic component, one end of elastic component is supported on the cascaded surface of fastener inner chamber, the other end is supported on that elastomeric bottom is provided with is set on the bearing on the gib head column connecting portion, have certain movable space between fastener and the hanging ring, that end that exposes to hanging ring at gib head column connecting portion is provided with keeper.
The fastener of this structure, by downward stretching fastener, make projection on the fastener upper surface leave the opening of crook, can realize article are hooked fastener this moment, when fastener finishes, decontrol fastener, fastener will be under the restoring force effect of elastic component self-return, thereby drive the projection of fastener upper surface and the sealing of crook hook openings side, thereby the object of avoiding connecting comes off.The fastener of this structure is owing to changed the fit form of existing fastener and gib head, therefore changed the low shortcoming of auxiliary section tensile strength that existing gib head is matching with fastener, simultaneously owing to the activity of the relative gib head of fastener is passed through the form realization of stretching, just make the structure tight Minato very of whole fastener, attractive in appearance, and easy to operate.
On the outer peripheral face of fastener, be symmetrically arranged with two grooves that make things convenient for handgrip.
On the outer peripheral face of fastener, be symmetrical arranged two grooves, can be convenient for people to hand and grabbing fastener stretching fastener.
The groove surfaces of fastener is provided with the friction line.
The friction line is set on groove surface, can improves the frictional force of hand and fastener, thus easy for people to use.
The bottom of described crook is a cylinder, and the cylinder of that side-lower of hook openings of crook is provided with chute, the projection on the fastener upper surface moves up and down realization and the hook openings side of crook at this chute sealing with separate.
Bottom in crook is provided with chute, can play the effect of holding fastener upper surface projection on the one hand, can play the effect that contacting piece positions on the other hand.
The thickness of projection equates on the chute degree of depth of described crook bottom and the fastener.
When the chute degree of depth equates with the thickness of fastener projection, in this chute of embedding that the projection of fastener can be complete, therefore make both faying faces realize seamlessly transitting.
The outer peripheral face of described fastener is a cylinder, and the cylinder of fastener equates with the cylinder external diameter of crook bottom.
When the external diameters such as cylinder of fastener outer peripheral face and crook bottom, can improve the aesthetic property of gib head outward appearance, make it have good lines.
Described keeper or be a kind of collar, or be threaded connector.
Threaded connector is a nut.
Described elastic component is a spring.
The column connecting portion of described gib head bottom is cylindric.
Columned column connecting portion has big cross section, has enough pulling force simultaneously to guarantee gib head, has the minimum advantage that takes up space again.
In sum, advantage of the present utility model is:
This practicality is newly by the relative motion mode between gib head and the fastener in the change fastener, thereby it is thinner at the auxiliary section wall thickness that matches with fastener to have changed existing gib head, the shortcoming that tensile strength is low, and have structure tight Minato very, advantage attractive in appearance, easy to operate.
