Description
Technical field
The present invention relates to a kind of anti-theft latch fastener, specifically be used for the anti-theft latch fastener of sales field article such as supermarket.
Technical background
The clothes of sales fields such as supermarket or some valuable small articles need be installed anti-theft latch fastener, wherein a kind of anti-theft latch fastener, there is the tapered end of iron pellet shot from a slingshot to fasten purl in utilizing exactly, in client's clearing, the cashier uses magnetic force and unblanks, this cylinder lock, the stem stem of lock core is a metal cylinder at present, and stem stem top is used to withstand spring, and the stem stem bottom has three complete bullet groove on same horizontal plane, bullet groove connects mutually, in the time of assembling, the workman need be tucked into bullet groove with pellet shot from a slingshot, is put in the lower cover together with lock core then, because lock core is very little, pellet shot from a slingshot is littler, and pellet shot from a slingshot falls easily in the time of assembling, and the bullet groove of the hollow out of stem stem bottom is processed also more complicated, inconvenient operation, efficient are also low.
Summary of the invention
The invention provides a kind of new article anti-theft snap close, can conveniently process and assemble, raise the efficiency.Concrete technical scheme is:
A kind of article anti-theft snap close comprises tapered end and purl; Fluted on the purl, leave lockhole on the tapered end and insert for purl; Tapered end comprises loam cake, lower cover, lock core, the loam cake inwall has projection, the oral area of lower cover extends out projection, can withhold mutually with the loam cake internal projection, lower cover is an inverted cone, mouth diameters is greater than base diameter, and lock core places in the cavity of loam cake and lower cover composition, and the lockhole on same straight line is arranged respectively on loam cake, lower cover and the lock core; Lock core comprises stem stem, spring and a plurality of pellet shot from a slingshot, and in the bullet groove of pellet shot from a slingshot below stem stem, pellet shot from a slingshot is distributed in around the lockhole of lower cover, one end of spring is positioned at the stem stem top, the spring other end withstands on the top in the loam cake, and the bullet groove of stem stem below is a half opening, and bullet groove is made by elastomeric material.
As preferred version, the bottom centre of lower cover concaves, and forms the groove of a ring-type at the lower cover inner bottom part.Pellet shot from a slingshot is put into the bottom of lower cover, will be distributed to around the lockhole, so that assembling.
In assembling, as long as pellet shot from a slingshot is placed in the lower cover, pellet shot from a slingshot is distributed in the endless groove of lower cover inner bottom part, directly be pressed onto stem stem in the lower cover again, the bullet groove of the half opening shape on the stem stem snaps onto pellet shot from a slingshot in the bullet groove under the effect of pressure, above stem stem, install spring then, buckle loam cake, just can finish assembling process.
The quantity preferred version of pellet shot from a slingshot is 3, the size of pellet shot from a slingshot and the diameter of lower cover have relation, stem stem withstands on pellet shot from a slingshot the bottommost of lower cover under the effect of spring, when purl enters, can push pellet shot from a slingshot, pellet shot from a slingshot withstands stem stem and moves to the top of lower cover, because the upper diameter of lower cover is bigger, it is big that the space between the pellet shot from a slingshot also just becomes, and purl can pass, after purl enters tapered end, stem stem is because the elastic force effect of spring is pushed up pellet shot from a slingshot toward the lower cover bottom, because past more base diameter is more little, the space that pellet shot from a slingshot directly forms is just more little, in on the groove of pellet shot from a slingshot on purl, just can pin purl.
The present invention program can also further optimize:
Loam cake is made by plastics; Lower cover is made by metal material.
The pellet shot from a slingshot optimal number is three, and the quantity of pellet shot from a slingshot is the same with bullet groove on the stem stem.
Article anti-theft snap close provided by the invention, simple in structure, especially stem stem is processed than original convenience, and packaging technology is quick, can not fall pellet shot from a slingshot.
Description of drawings
Fig. 1 is the embodiments of the invention structural representations.
The specific embodiment
As shown in Figure 1, the tapered end loam cake 1 of snap close and lower cover 2 are sectional view, and lock core is an elevation.
Leaving lockhole 61,62 on the tapered end inserts for purl; Tapered end comprises loam cake 1, lower cover 2, lock core, loam cake 1 inwall has projection, the oral area of lower cover 2 extends out projection, can withhold mutually with loam cake 1 internal projection, lower cover 2 is inverted cones, mouth diameters is greater than base diameter, and lock core places in the cavity of loam cake 1 and lower cover 2 compositions, and the lockhole on same straight line is arranged respectively on loam cake 1, lower cover 2 and the lock core; Lock core comprises stem stem 3, spring 4 and three pellets shot from a slingshot 5, in the bullet groove of pellet shot from a slingshot 5 below stem stem 3, pellet shot from a slingshot 5 is distributed in around the lockhole 61 of lower cover 2, one end of spring 4 is positioned at stem stem 3 tops, spring 4 other ends withstand on the top in the loam cake 1, the bullet groove of stem stem 3 belows is half openings, and bullet groove is made by plastics.Stem stem 3 is that aluminium is made, and loam cake 1 is that plastics are made, and lower cover 2 is that aluminium is made.
In the time of assembling, need only the bottom that three pellets shot from a slingshot 5 is put into lower cover 2, stem stem 3 directly is pressed onto in the lower cover 2, the bullet groove of three half opening shapes on the stem stem 3 snaps onto three pellets shot from a slingshot 5 in the bullet groove under the effect of pressure, above stem stem 3, install spring 4 then, buckle loam cake 1..
As preferred version, the bottom centre of lower cover 2 concaves, and forms the groove of a ring-type at the lower cover inner bottom part.
