Specific implementation mode

The utility model is described further below in conjunction with the accompanying drawings.

A kind of novel plastic seal, as shown in Figures 1 to 4, including lock nut 1, lock rope 2 and for by the lock rope 2 lock Lock body 3 in the lock nut 1, the generally cuboid of the lock nut 1, inner hollow and top are equipped with opening, the lock Front and back corresponding lock cord hole 11 is offered on 1 front and rear sides wall of cap, the top of the inner wall of 1 left and right sides of the lock nut is fixed There is latch 12, latch 12 is pointed protrusion as shown in Figure 1 or is in reclinate arc；One end of the lock rope 2 is fixed on On the lock nut 1；The lock body 3 includes the first rectangular pressing plate 31 and is fixed on vertically on 31 lower face of the first pressing plate For the card handle 32 of the locking lock rope 2, columnar elastic force strip 33, institute are respectively and fixedly provided at left and right sides of 32 lower part of card handle It states elastic force strip 33 and tilts upward extension and symmetrical about the card handle 32.When in use, by the free end of lock rope 2 from lock nut 1 On a lock cord hole 11 penetrate and after another lock cord hole 11 is pierced by, then lock body 3 is inserted into lock nut 1 can realize envelope Print locking, it is simple to operate；After lock body 3 is inserted into lock nut 1, the top of elastic force strip 33 is contradicted to be not easy point below latch 12 It opens, anti-theft capability is strong, and the bottom end of card handle 32 presses lock rope 2 and being fixed in lock nut 1 makes it that can not extract out, lock body 3 and lock nut 1 Structure it is simple, easy to manufacture and of low cost.

In the present embodiment, the metallic channel 321 for 2 insertions of restricting for the lock is offered on the vertical direction of the card handle 32, 32 bottom end of card handle offers the straight slot 322 for fixing 2 positions of the lock rope, the metallic channel 321 and 11 phase of lock cord hole It is corresponding.In this way, the lock rope 2 in lock nut 1 can be embedded into metallic channel 321 and straight slot 322, it is made not deviate by or take off Constraint from card handle 32, to improve security performance.

In the present embodiment, the depth of the metallic channel 321 is not less than the diameter for locking rope 2, in this way, facilitating envelope Make the lock rope 2 in lock nut 1 preferably embedded when print locking and is fitted in metallic channel 321.

In the present embodiment, the thickness of the card handle 32 is equal with the width of cavity inside the lock nut 1, sets in this way It sets, card handle 32 is inserted into lock nut 1 and will not shake, and will not give lock rope 2 reserved extra activity space, prevent lock rope 2 from lock nut 1 Interior extraction.

In the present embodiment, several lateral non-skid bands 3211 are equipped in the metallic channel 321, in this way, can increase Frictional resistance in metallic channel 321 prevents the sliding in metallic channel 321 of lock rope 2, enhances anti-theft capability.

In the present embodiment, it is connected by connecting rope 4 between the lock body 3 and lock nut 1, to prevent lock nut 1 or lock body 3 from losing It loses.

In the present embodiment, the bottom end of the lock nut 1 is fixed with the second rectangular pressing plate 13, in this way, when lock body 3 is inserted When entering to lock nut 1, convenient firmly the first pressing plate 31 of pressing and the second pressing plate 13, to make lock body 3 is easier to be inserted into lock nut 1 In locked.

Embodiment of above is merely to illustrate the utility model, and is not limitation of the utility model, related technology neck The those of ordinary skill in domain, in the case where not departing from the spirit and scope of the utility model, can also make a variety of changes and Modification, therefore all equivalent technical solutions also belong to the scope of the utility model, the scope of patent protection of the utility model is answered It is defined by the claims.
