Description

For the round end self-adhesion injection structure of VELCRO

Technical field

The utility model relates to a kind of round end self-adhesion for VELCRO injection structure.

Background technology

Traditional self-adhesion is that formula VELCRO all adopts hook shape face and hair side to fit, the hook shape face of VELCRO adopts nylon monofilament to be woven on a face of base band, then cut hook machine through monofilament the continuous monofilament be woven in blank strip is cut, make the single monofilament head after cutting form one and hook shape, utilize the hook of every root monofilament head to be formed on a face of base band and hook shape face.But the VELCRO of said structure after a long time use, the silk of nylon monofilament head hooks will by slowly stretching, and VELCRO laminating effect can be reduced gradually, and service life is short; On the other hand, base band should arrange hook shape face hair side is set again, difficulty and the production cost of production can be increased, namely need different technological processes.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is the injection of the round end self-adhesion for the VELCRO structure providing a kind of long service life.

For achieving the above object, the utility model provides following technical scheme: a kind of injection of the round end self-adhesion for VELCRO structure, comprise base band, base band is gathered and is provided with multiple injection hook, each described injection hooks and has included joint pin and spheroid, and one end of joint pin is fixedly connected on base band, and spheroid is connected to the other end of joint pin, distance often between adjacent two described spheroids is less than the diameter of spheroid, and the axial length of joint pin is more than or equal to the diameter of spheroid.

Preferably, the rounded setting of shaft section of joint pin, and the shaft section area from spheroid one end to base band one end increases gradually.

Preferably, the distance between the joint pin often described in adjacent two and the equal diameters of spheroid.

Preferably, the obverse and reverse of base band is provided with injection hook.

Compared with prior art, the utility model has the advantages that, obverse and reverse is in the process of bonding, by the elastic deformation that injection hooks, between the joint pin that spheroid on front is snapped onto on reverse side, spheroid simultaneously on reverse side snaps onto between the joint pin on front, thus formation tacky state, and relative and traditional VELCRO, there is not hair side and hook shape face in the utility model, namely can not exist because the silk hook hooked on shape face is straightened and cause the situation that VELCRO can not bond, so this setting extends service life of the present utility model; On the other hand, because the utility model is in the process of self-adhesion, be hooked by same injection to realize bonding, namely there is not the differentiation in hair side and hook shape face, so the utility model is when producing, its production technology can reduce, thus can reduce production cost.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, the round end self-adhesion injection constructive embodiment that the utility model is used for VELCRO is described further.

A kind of injection of the round end self-adhesion for VELCRO structure, comprise the base band 1 with obverse and reverse, in the technical program, base band is formed by acrylic glue compound (bonding) by the first base band 11 and the second base band 12, and front 2 and reverse side 3 lay respectively in the first base band 11 and the second base band 12.Front 2 and reverse side 3 all gather and is provided with multiple injection hook 4, penetrate hook 4 is uniform distribution simultaneously; Each described injection hooks 4 and has included joint pin 42 and spheroid 41, and one end of joint pin 42 is by being fixed on base band, and spheroid 41 is connected to the other end (spheroid 41 and joint pin 42 are integrated) of joint pin 42; Distance often between adjacent two described spheroids 41 is less than the diameter (but being greater than 1/2nd of spheroid 41 diameter) of spheroid 41, this setting can make spheroid 41 have limit function, spheroid 41 on reverse side 3 can be fastened between the adjacent joint pin 42 on front 2 by the spheroid 41 namely on front 2, spheroid 41 on front 2 can be fastened between the adjacent joint pin 42 on reverse side 3 by the spheroid 41 in like manner on reverse side 3, and the utility model can be made to play the function of self-adhesion; The axial length of joint pin 42 is more than or equal to the diameter of spheroid 41, and this setting can provide space for spheroid 41 is fastened between joint pin 42; Simultaneously in the utility model, compare and the mushroom head structure (the utility model is ball structure) in tradition, have more durable usability, because when traditional VELCRO adopts mushroom head engaging to realize bonding, because the width of mushroom head is relatively large, so in the process of engaging mutually (or in process of dismounting mutually), mushroom head on front 2 can be larger with the conflict area of the mushroom head on reverse side 3, can be larger so mushroom head is relative with the deformation of joint pin 42, so the normal service life of injection hook 4 can be had influence on to a certain extent; And in the utility model, because the conflict area between spheroid 41 and spheroid 41 is less, so in the process split or bond, the deformation of spheroid 41 and joint pin 42 is also relatively little, so to a certain extent, physical life of the present utility model can be relatively long.

Further, the rounded setting of shaft section of joint pin 42, and increase gradually from the shaft section area of spheroid 41 one end to base band one end, this arranges the bonding strength that can increase on the one hand between injection hook 4 and base band, can further increase normal service life of the present utility model.

Further, distance between joint pin 42 often described in adjacent two and the equal diameters of spheroid 41, this is arranged so that when spheroid 41 snaps onto after between joint pin 42, spheroid 41 can not produce squeezing action to joint pin 42, namely on the same face, adjacent two spheroids 41 of (front 2 or reverse side 3) can not produce extruding force to the joint pin 42 on another side, cause joint pin 42 that permanent deformation occurs, the diameter of joint pin 42 is diminished and the structural strength caused diminishes, if when front 2 and reverse side 3 being split under squeezed state simultaneously, because the extruding force between spheroid 41 and joint pin 42 is excessive, frictional force that is that cause is excessive, be easy to there is the possibility broken by joint pin 42, so the arrangement increases practicality of the present utility model, if on the other hand the distance between adjacent joint pin 42 is arranged excessive time, spheroid 41 can be caused can not to be effectively fastened between joint pin 42, namely can to have influence on normal bonding force of the present utility model.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
