Abstract
The utility model discloses a plastic fastener which comprises a fastener body and a chock. A cap is arranged at one end of the fastener body and chucks are arranged at the other end of the fastener body; a fork pocket and an opening are arranged at the inner side of each chuck; in this way, the chucks can be elastic and can bend towards the inner sides under external force to change the distance between the chucks and can restore to the original places after the external force is removed; the fork pocket is provided with a retainer boss for preventing the chock from sliding out after being inserted into the fork pocket; and a fork head and a clamping boss are arranged on the chock. The plastic fastener is made of engineering plastic and is good in strength and environment-friendly and can be produced in batch production in various specifications. The plastic fasten can reduce cost while improving production efficiency and is widely applicable for fastening hinged pieces and assembled parts.
Description
Technical field
The utility model belongs to fastening, support or erecting device technical field, is specifically related to a kind of plastic fastener.
Background technique
Fastening piece between the existing plastic fittings adopt usually rivet or bolt nut come fastening, yet the fastening piece of this metal gets rusty easily, the cost height, assembles cumbersome.
Summary of the invention
Goal of the invention of the present utility model is that a kind of plastic fastener will be provided, and this fastening piece is made raw material with engineering plastics, and intensity is good, environmental protection, can produce the fastening piece of all size in batches, has also improved manufacturing efficiency when reducing cost.Can be widely used in the fastening of articulated elements and assembly parts.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of plastic fastener, it comprises fastener, chock, an end is provided with the cap head on the described fastener, an other end is provided with dop, be provided with fork pockets and opening in the dop inboard, dop is just flexible like this, can be under the external force crooked to the inside distance that changes between the dop, external force is cancelled and can be returned to original position, and is provided with the retaining platform in the fork pockets and prevents to skid off after chock from inserting fork pockets.Described chock is provided with jaw and Ka Tai.When fastening, an end that only needs fastener to be had dop is aimed at the through hole that fastener is provided with, slightly firmly make the crooked to the inside distance of dop less than through-hole diameter, pass through hole, at this moment restore to the original state after the power effect that dop does not have to push, thereby tightly pin the cap head of the fastened body of fastener and dop both sides, then chock is being inserted in the fork pockets, prevent that fastener in use is subjected to the external force collision or vibrations make the dop bending cause fastener to come off, more firm fixedly fastener.
Above-mentioned plastic fastener, one of its structure are to be that cap head and dop that fastener is provided with are all big than fastener body portion diameter.
Above-mentioned plastic fastener, one of its structure be that fastener is provided with dop can be crooked after being subjected to external force extruding, and the overall dimensions after the bending is less than or equal to the diameter of fastener body portion, can return on the original state position again when external force is cancelled.
Above-mentioned plastic fastener, one of its structure are to be that the retaining platform that is provided with in the fork pockets cooperates with the Ka Tai that chock is provided with, and block mutually, prevent that chock from skidding off fork pockets, and dop can not be curved inwardly.

Embodiment
That represented by Fig. 2-Fig. 8 is the utility model embodiment, it comprises fastener 1, chock 2, an end is provided with cap head 1-1 on the described fastener 1, an other end is provided with dop 1-2, owing to be provided with fork pockets 1-3 and opening 1-4 in dop 1-2 inboard, dop 1-2 is just flexible like this, can be under external force the distance between the crooked to the inside change dop 1-2, external force is cancelled and can be returned to original position, and is provided with retaining platform 1-5 in the fork pockets 1-3 and prevents to skid off after chock 2 from inserting fork pockets 1-3.Described chock 2 is provided with jaw 2-1 and Ka Tai 2-2.When fastening, an end that only needs fastener 1 to be had dop 1-2 is aimed at the through hole 3 of U jacket one side, slightly firmly make the crooked to the inside ultimate range of dop 1-2 less than through-hole diameter, pass the through hole of through hole 4-1 to the U jacket opposite side that steering head is provided with, at this moment automatically spring open reinstatement after the power effect that dop 1-2 does not have to push, be stuck in 3-2 on the round block face on the U jacket, thereby tightly pin the cap head 1-1 and the dop 1-2 both sides of U jacket 3 and steering head 4 fastened bodies 1, elasticity by plastics itself squeezes into chock 2 in the fork pockets 1-3 along opening 1-4 then, retaining platform 1-5 and card platform 2-2 fasten mutually, make chock 2 being buckled in the fork pockets 1-3 tightly, also make dop 1-2 not curve inwardly, thereby prevent that fastener is subjected in use that external force is collided or vibrations make dop 1-2 bending cause fastener 1 loosening and come off more firm pinning fastener.
