Abstract

The utility model relates to a bolt formula locking device, including lock body, jump ring and bolt, be provided with the bolt hole on the lock body, be used for inserting the bolt, bolt appearance and the cooperation of bolt hole closely are provided with on bolt hole and the bolt and prevent bolt pivoted both sides limit, and its purpose prevents that lock body and bolt from being opened the possibility rotating the in -process, the bolt front end is provided with two inclined planes, is provided with two oblique draw -in grooves thereafter, when inserting the lock body, and the inclined plane spreading jump ring of front end, in messenger's jump ring can block to go into oblique draw -in groove, when drawing the bolt hard, the jump ring was under the effect on draw -in groove inclined plane, and the centering is drawn close, ensures that the jump ring is not opened, the bolt rear end is provided with a cylindrical table, and its diameter is greater than the bolt hole, and its purpose prevents in the tiny picking lock tool insertion hole. The utility model discloses a device is executed and is sealed firmly, reliable, and operation process is simple, and the theftproof performance is good.

Description

Bolt-type locking device

Technical field

This utility model belongs to container apparatus technical field, is specifically related to a kind of bolt-type locking device.

Background technology

The disposable sealing of most applying on the container of haulage vehicle at present, it is easy to be opened or replicate, shipped goods Safety can not be guaranteed；Some e-seals occurred in recent years, structurally and functionally there is complexity in it, Product cost is high；One-time lock is because of its low price, the main flow being still in logistic industry.

Utility model content

For the deficiency overcoming existing one-time lock to be easily opened and replicate, this utility model provides a kind of bolt-type Locking device, this apparatus structure is simple,

To achieve these goals, the technical solution of the utility model is as follows.

A kind of bolt-type locking device, including lock body, jump ring and latch, lock body is provided with pin hole, slotting for inserting Pin, latch profile coordinates with pin hole closely, pin hole and latch is provided with the dual-side preventing latch from rotating, its mesh Be to prevent lock body and latch to be opened in rotation process possibility；Latch front end is provided with two inclined-planes, is provided with thereafter two Tiltedly draw-in groove, when inserting lock body, the inclined-plane spreading jump ring of front end, make jump ring can snap in oblique draw-in groove, pull at latch Time, jump ring, under the effect on draw-in groove inclined-plane, is drawn close to center, it is ensured that jump ring is not flared；Latch rear end is provided with a circle Pylon, its diameter is more than pin hole, and its purpose prevents tiny picklock from inserting in hole.

Having the beneficial effects that of this utility model: this utility model device is executed and secured solid, reliable, and operating process is simple, anti- Robber's performance is good.

Accompanying drawing explanation

Fig. 1 is bolt-type steel wire seal structural representation in this utility model embodiment.

Fig. 2 is that in this utility model embodiment, bolt-type height protects seal structure schematic diagram.

Fig. 3 is the schematic diagram that in this utility model embodiment, latch inserts pin hole.

Detailed description of the invention

Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described, in order to be better understood from this practicality new Type.

Bolt-type locking device in the present embodiment, this device is used in production bolt-type steel wire seal, high protects strip of paper used for sealing etc. Secondary property lockset, including lock body 1, jump ring 2 and latch 3, the pin hole on lock body 1 has two straight troughs, on latch 2 Also added with two chimbs, coordinating with pin hole, after preventing latch from inserting, latch rotates in lock body；The connection of other forms, As square, rectangle etc., prevent the structure that latch rotates, equally applicable eigen.Latch 2 front end dual-side has draw-in groove, Inwardly there is constant slope on the retaining limit of groove, its objective is when plug pin, the component that the jump ring in draw-in groove is produced by retaining limit, Draw close to axle center, prevent the trend that latch moves out because stress is excessive.On lock body 1 outside pin hole steel wire rope 4 with insert Pin 2 rear end diametric fit is tight, and the diameter of latch rear end, more than the pin hole on lock body, prevents tiny picklock Enter.

In fig. 1 and 2, in the present embodiment, latch 3 inserts in lock body 1, and the jump ring 2 in lock body 1 snaps in latch 3 The oblique draw-in groove of front end, latch 3 can not be extracted, it is achieved disposably executes the purpose of lock, and skewed slot is primarily used to prevent latch quilt Extracting, when plug pin, jump ring 2, under the effect of skewed slot, is selected to center, will not be flared out, therefore jump ring 2 Without departing from opening draw-in groove.

In an illustrated embodiment, there is the round platform of a diameter of 6mm latch 3 rear end, and its diameter is more than pin hole full-size 5mm, causes round platform all to cover the fit clearance of pin hole and latch, prevents tiny picklock from inserting.

In the embodiment shown in fig. 3, inserting in pin insertion hole, because there being two chimbs to coordinate with hole, latch can not be at latch Rotate in hole, it is therefore prevented that latch is opened because of rotation possibility.

The above is preferred implementation of the present utility model, it is noted that for the ordinary skill people of the art For Yuan, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and Retouching is also considered as protection domain of the present utility model.

Claims

1. a bolt-type locking device, it is characterised in that: include lock body, jump ring and latch, described lock body is arranged Having pin hole, be used for inserting latch, described latch profile coordinates with pin hole closely, and described pin hole and latch are arranged There is the dual-side preventing latch from rotating；Described latch front end is provided with two inclined-planes, is provided with thereafter two oblique draw-in grooves；Described slotting Pin rear end is provided with a cylinder table, and its diameter is more than pin hole.
