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 the sales field article such as supermarket.
Technical background
The clothes of the sales fields such as supermarket or some valuable small articles need to be installed anti-theft latch fastener, a kind of anti-theft latch fastener wherein, there is the tapered end of iron pellet 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 for withstanding spring, and the stem stem bottom has three complete bullet groove in same level, bullet groove connects mutually, in the time of assembling, the workman need to be tucked into bullet groove with pellet, then is put in the lower cover together with lock core, because lock core is very little, pellet is less, and pellet easily falls 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 burglar-proof padlock, can conveniently process and assemble, raise the efficiency.Concrete technical scheme is:
A kind of article burglar-proof padlock 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 mutually withhold with the loam cake internal projection, lower cover is 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, and in the bullet groove of pellet below stem stem, pellet 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 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 is put into the bottom of lower cover, will be distributed to around the lockhole, so that assembling.
In assembling, as long as pellet is placed in the lower cover, pellet 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 in the bullet groove under the effect of pressure, then above stem stem, install spring, buckle loam cake, just can finish assembling process.
The quantity preferred version of pellet is 3, the size of pellet and the diameter of lower cover have relation, stem stem withstands on pellet the bottommost of lower cover under the effect of spring, when purl enters, can push pellet, pellet withstands stem stem and moves to the top of lower cover, because the upper diameter of lower cover is larger, it is large that the space between the pellet 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 toward the lower cover bottom, because more past base diameter is less, the space that pellet directly forms is just less, in on the groove of pellet 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 optimal number is three, and the quantity of pellet is the same with bullet groove on the stem stem.
Article burglar-proof padlock provided by the invention, simple in structure, especially stem stem is processed than original convenience, and packaging technology is quick, can not fall pellet.
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 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 mutually withhold 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 5, in the bullet groove of pellet 5 below stem stem 3, pellet 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, as long as three pellets 5 are put into the bottom of 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 5 in the bullet groove under the effect of pressure, then above stem stem 3, install spring 4, 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.
