Description
Technical field
The utility model relates to slide fastener and its spare and accessory parts field, more specifically a kind of rushing with pulling-on piece limiting
Press pull head.
Background technology
In the prior art, the pull head of slide fastener includes die casting pull head and punching press pull head, its whole life of traditional die casting pull head
Production process is more, and production operation is more troublesome, and parts assembling speed is slower, is unfavorable for improving the production efficiency of pull head.Punching press
Pull header structure is relatively simple, is generally formed after punch process and bending processing by a pressed sheet, but traditional punching press is drawn
When in use, after pulling-on piece rotates certain angle or direct 180 degree is overturn, the needle lock on pull head is just for head and die casting pull head
It can set upward, this hour hand lock is easy for damaging clothing or fabric, and fabric is made to scratch or fluff, can also be scratched when serious
The skin of people.
In order to overcome this technical disadvantages existing for this pull head, China filed in the applicant on 06 02nd, 2006 is specially
Profit：A kind of Novel puller, Authorization Notice No. are：CN 2909903Y, the Novel puller in the side of pull head ontology by setting two
Block can effectively prevent being flipped up for the pulling-on piece, its angle overturn is made to control in certain range, avoids its right
Clothing or fabric generate injury.But program application is die casting pull head, block is arranged on the pull head ontology, and is directed to
In existing punching press pull head, pull head is disposable punching press, bends, is difficult to set two catch on pull head ontology, so raw
There are significant limitations in production.
Utility model content
The utility model discloses a kind of punching press pull head with pulling-on piece limiting, and main purpose is to overcome existing skill
Art above shortcomings and shortcoming.
The technical solution adopted in the utility model is as follows：
A kind of punching press pull head with pulling-on piece limiting, including stamping forming pull head ontology, shrapnel and pulling-on piece, the pull head
Ontology includes upper flange, lower wing plate and branch core, and the front end of the upper and lower wing plate is set by the branch core integrally connected, institute
It states and one is offered on upper flange from lock claw through-hole, and the front end side wall of the branch core is equipped with a riveted point being vertically arranged, institute
The front and rear ends vertically bending extension separately down of shrapnel is stated, is respectively formed a shrapnel riveted end and a shrapnel from lock claw end, institute
It states shrapnel riveted end and the riveted point of the branch core and is adapted ground stake-fastening and connect, the shrapnel is from the cooperation activity of lock claw end
Wear it is described offer two forward and backward symmetrically arranged trepannings respectively from the middle part of lock claw through-hole, the shrapnel, on the position of opening
Shrapnel is bent downward, and is respectively formed a symmetrically arranged position-limited claw, and the pulling-on piece cooperation activity limiting is installed in two limit
Between the pawl of position；Arranged on left and right sides in the middle part of the shrapnel extends outwardly respectively, forms a symmetrically arranged catch boss, the drawing
Coordinate after piece overturning and be blocked on the catch boss.
Further, the shrapnel, shrapnel riveted end, shrapnel from lock claw end, two position-limited claws and two catch boss be one
Forming structure.
Further, the rounded boss structure of catch boss.
Further, the shrapnel riveted end and shrapnel distinguish arc-shaped bending from lock claw end and the junction of the shrapnel
Shape structure.
Further, two position-limited claw is set in " eight " font structure.
By the above-mentioned description to the utility model it is found that compared to the prior art, the utility model has the advantage of：
The utility model is respectively arranged with a catch boss by the arranged on left and right sides in the middle part of shrapnel, which uses
Overturning is continued up in blocking pulling-on piece, the overturning that pulling-on piece occurs 180 ° is avoided to cause the injury of clothing or fabric, realizes that punching press is drawn
The technical issues of being difficult to set catch on head, effectively overcomes above-mentioned technical disadvantages.Meanwhile the utility model passes through to shrapnel
The improvement of structure not only makes elastic piece structure simpler, better reliability, and the assembling for being more convenient entire zipper head is set
It puts, is more advantageous in practical production and assembly.

Specific embodiment
Illustrate to further explain the structure diagram of the utility model with reference to the accompanying drawings.
As shown in Figures 1 to 5, a kind of punching press pull head with pulling-on piece limiting, including stamping forming pull head ontology 1, bullet
Piece 2 and pulling-on piece 3, the pull head ontology 1 include upper flange 11, lower wing plate 12 and branch core 13, the upper and lower wing plate（11、12）
Front end set by 13 integrally connected of branch core, offer one from lock claw through-hole 14, and the core branch on the upper flange 11
The front end side wall of body 13 is equipped with a riveted point 15 being vertically arranged, and the front and rear ends of the shrapnel 2 are vertically bent separately down
Extension is respectively formed a shrapnel riveted end 21 and a shrapnel from lock claw end 22, the shrapnel riveted end 21 and the branch core 13
