Description

A kind of locking device for draw-string formula packaging bag

Technical field

This utility model relates to a kind of snap close retaining mechanism, particularly discloses a kind of locking for draw-string formula packaging bag and fills Put.

Background technology

Now in packing technique field, existing various bundle mouth packaging bags, all receive with unidirectional or bidirectional pulling mode Tightly.The product not having a kind of manner of packing can lock and realize simultaneously location and review.Cannot article in protective packing bag Uniqueness and safety, more cannot carry out the location of product constantly and review.In Internet of Things field, one is not more had to lock Determine and there is the product positioning tracing function constantly simultaneously.

Summary of the invention

The purpose of this utility model is to overcome defect present in prior art, it is provided that a kind of simple in construction, encapsulation side Just, it is widely used, low cost, it is simple to the locking device for draw-string formula packaging bag of large-scale mass production.

This utility model is achieved in that a kind of locking device for draw-string formula packaging bag, it is characterised in that: include Tapered end plate, label housing, described tapered end plate is connected as a single entity with label housing, and described tapered end plate is provided with 2 ~ 4 for through taking out The threading passage of rope, is provided with the unidirectional double wedge stoping draw-string to exit described threading passage, described label shell in described threading passage The internal electronic tag that is provided with, described electronic tag is active electronic label or passive electronic label；Described active electronic label bag Include surface-mounted integrated circuit, the RFID chip being connected respectively, supply module, signal projector, described signal with described surface-mounted integrated circuit Emitter is connected with described RFID chip and supply module respectively.

Described unidirectional double wedge by metallic elastic sheet, be connected in the teeth portion in the middle of metallic elastic sheet and form, described metallic elastic sheet It is fixed on described tapered end plate and described teeth portion is positioned at described threading passage.

Described unidirectional double wedge is 2 ~ 6 pointed projections being connected as a single entity with the inwall of described threading passage.

Described active electronic label also includes the positioning chip being connected respectively with described surface-mounted integrated circuit, signal projector.

Described supply module is battery.

Described label housing is provided with information code printing zone.

The beneficial effects of the utility model are: this utility model not only strengthens the package strength of bundle pocket, realizes simultaneously Position constantly and review.Being greatly reinforced packaging level of security, and simple in construction, encapsulation is convenient, is widely used, low cost, It is easy to large-scale mass production.

Detailed description of the invention

With reference to the accompanying drawings 1, Fig. 2, in conjunction with Fig. 3, this utility model includes tapered end plate 1, label housing 2, described tapered end plate 1 and mark Signing housing 2 to be connected as a single entity, described tapered end plate 1 is provided with 2 ~ 4 for the threading passage 3 through draw-string 4, described threading passage 3 Inside be provided with and stop draw-string 4 to exit the unidirectional double wedge 5 of described threading passage 3, described unidirectional double wedge 5 by metallic elastic sheet 51, be connected in Teeth portion 52 in the middle of metallic elastic sheet 51 forms, and described metallic elastic sheet 51 is fixed on described tapered end plate 1 or tapered end plate 1 interior Portion and described teeth portion 52 are positioned at described threading passage 3.Being provided with electronic tag in described label housing 2, described electronic tag is Active electronic label 6 or passive electronic label, described passive electronic label is usually RFID label tag, and described RFID label tag is existing Matured product, itself structure is not repeated by this utility model.Described active electronic label 6 includes surface-mounted integrated circuit 61, divides The RFID chip 62 that is not connected with described surface-mounted integrated circuit 61, supply module 63, signal projector 64, positioning chip 65, described Signal projector 64 is connected with described RFID chip 62, positioning chip 65 and supply module 63 respectively.Described supply module 63 is Battery.Described label housing 2 is provided with information code printing zone 21, and described information code includes company numbering, Quick Response Code, bar code Or the combination of any one or a few in security code.

Embodiment one:

According to Fig. 3 ~ Fig. 4, described unidirectional double wedge 5 is unlike those described above, and described unidirectional double wedge 5 is 2 ~ 6 and wears with described The pointed projections that the inwall of line passage 3 is connected as a single entity, is 5 pointed projections in the present embodiment, and remaining structure is the most above-mentioned.

When this utility model uses, by the draw-string 4 of bundle pocket through the threading passage 3 on described tapered end plate 1, draw-string 4 is worn After entering, under the effect of unidirectional double wedge 5, can only move along one direction, after draw-string 4 tightens up, it is impossible to make draw-string 4 new from this practicality Type exits, strengthens the package strength of bundle pocket, achieved by described electronic tag simultaneously and position constantly and review.Significantly Strengthening packaging level of security, this utility model simple in construction, encapsulation is convenient, is widely used, low cost, it is simple to extensive batch Produce and application.
