Abstract

The utility model discloses a novel plastic lock seal which solves the problem that the traditional self-locking type lock seal is easy to be adjusted artificially before the seal lock is closed; thereby changing the locking property of the lock seal; the utility model includes a plastic housing and an inserting piece inserted inside the housing; the inner cavity of the housing is provided with a core body; the two sides of the inner cavity of core body are respectively provided with an elastic hook; a bayonet I and a bayonet II which can be buckled with the elastic hooks are arranged in parallel on the inserting piece; two threading holes penetrating the upper surface and the lower surface of the housing are arranged on the housing; the inserting piece is also provided with through holes corresponding to the threading holes; the lock seal can not be adjusted artificially before being closed and can not be opened once the lock seal is closed; the utility model is safe and reliable.

Description

A kind of novel plastics lock-seal

Technical field

The utility model relates to a kind of novel plastics lock-seal that is used to block the locked of electrical metering facility or other facility, particularly a kind of self-locking.

Background technology

In the locked field of electrical metering equipment, the locked antifalse effect than original lead sealing seal of disposable self-locking is better at present, thereby has obtained to use widely.The general disposable self-locking that uses is locked, comprises plastic casing and inserts the plug-in unit of enclosure interior, and plug-in unit is provided with the elasticity hangnail, and the plastic casing inwall has the step that the elasticity hangnail is blocked, and is subjected to the obstruction of step after plug-in unit inserts and can't extracts backward.But be arranged on the elasticity hangnail on the plug-in unit, before locked complete closure, exist and utilized the gap between plug-in unit and the shell to adjust artificially, reduce locked security performance.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel plastics lock-seal, can't block performance to it and do artificial the adjustment before locked closure, and is safe and reliable.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of novel plastics lock-seal, the plug-in unit that comprises plastic casing and insertion enclosure interior, described housing inner chamber is equipped with core body, the core body inner chamber is provided with elastic hook, be set side by side with the bayonet socket I and the bayonet socket II that can be interlocked with elastic hook on the described plug-in unit, described housing is provided with two through wires holes that run through its top and bottom, also is provided with on the plug-in unit and the corresponding through hole of described through wires hole.

As improvement of the technical scheme, described housing inner chamber is provided with uncovered, describedly is embedded with the cover plate that is mated in uncovered; Described cover plate is provided with the leg that contacts with the housing internal chamber wall; Described core body front end is provided with the inside casing that the restriction plug-in unit seesaws; The through hole edge of described plug-in unit is provided with the zone of transition of envelope line; The through hole top of described plug-in unit also is provided with quil; But described housing inner chamber also is provided with the counterbore of setting-in ID chip.

As further improvement in the technical proposal, described housing and cover plate are shaped by transparent plastic.

The beneficial effects of the utility model are: owing to will be arranged on the inside of housing, before locked closure, can't do artificial the adjustment to it as the elastic hook of locked movable tight lock set, in case just can't open again after the locked closure, safe and reliable; And the design that bayonet socket I and elastic hook fasten in advance makes housing, core body and plug-in unit prepackage be one, in keeping, more convenient when receiving and using, avoids trouble.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified;

Fig. 1 is a structure explosive view of the present utility model;

Fig. 2 is the perspective view of core body;

Fig. 3 is the initial synoptic diagram that fastens of core body and plug-in unit;

Fig. 4 is a perspective view of the present utility model.

Embodiment

Referring to figs. 1 through Fig. 4, a kind of novel plastics lock-seal of the present utility model, comprise plastic casing 1 and insert the plug-in unit 2 of housing 1 inside, housing 1 inner chamber is equipped with core body 3, core body 3 inner chambers are provided with elastic hook 4, be set side by side with the bayonet socket I 21 and the bayonet socket II 22 that can be interlocked with elastic hook 4 on the described plug-in unit 2, housing 1 is provided with two through wires holes 11 that run through its top and bottom, also is provided with on the plug-in unit 2 and described through wires hole 11 corresponding through holes 23.In locked original state, the bayonet socket I 21 on the plug-in unit 2 fastens with elastic hook 4, and through wires hole 11 on the housing 1 and the through hole 23 on the plug-in unit 2 communicate.In use, envelope line 6 passes article to be blocked earlier, and the two ends of envelope line 6 are passed two through wires holes and the through hole 23 of housing 1 one side more respectively, passes from two through wires holes 11 of another side.Plug-in unit 2 is advanced in housing 1, through hole 23 and through wires hole 11 relative dislocation, envelope line 6 oppressed being locked between housing 1 and the plug-in unit 2, bayonet socket I 21 breaks away from elastic hook 4, and bayonet socket II 22 fastens the locked closure of finishing with elastic hook 4 thereupon.Because elastic hook 4 is arranged on the inside of housing 1 by core body 3, before locked closure, can't do artificial the adjustment to it, in case just can't open again after the locked closure, safe and reliable; And bayonet socket I 21 makes housing 1, core body 3 and plug-in unit 2 prepackages be one with the design that elastic hook 4 fastens in advance, makes keeping, more convenient when receiving and using, and avoids trouble.

With reference to Fig. 1, as improvement of the present utility model, housing 1 inner chamber is provided with in uncovered 12, uncovered 12 and is embedded with the cover plate 5 that is mated, and described cover plate 5 is provided with the leg 51 that contacts with housing 1 internal chamber wall.Adopt this structure, core body 3 can be easily be installed to housing 1 inner chamber from uncovered 12, utilize the ultrasonic fusing method with cover plate 5 by leg 51 with housing 1 welding, simple to operate, the production efficiency height.

With reference to Fig. 1, Fig. 2, described core body 3 front ends are provided with the inside casing 31 that restriction plug-in unit 2 seesaws, and guarantee that described plug-in unit 2 can only enter core body from inside casing 31 front and back, can not move up and down, and avoid occurring bigger gap and are adjusted locked performance by the lawless people utilization.But housing 1 inner chamber also is provided with the counterbore 13 of setting-in ID chip, but locked setting-in contains the RFID chip of global unique identifier, improves locked safety anti-fake performance.

With reference to Fig. 3, as further improvement of the utility model, through hole 23 edges of plug-in unit 2 are provided with the zone of transition 24 of envelope line 6, and through hole 23 tops also are provided with quil 25.During with through wires hole 11 relative dislocation, zone of transition 24 can allow envelope line 6 obtain mild transition at through hole 23, avoids sealing line 6 and fierce friction takes place and damage plug-in unit 2 with through hole 23 edges.In addition, the quil 25 of through hole 23 tops can strengthen the stiction between envelope line 6 and the plug-in unit 2, makes locked tight lock better effects if to envelope line 6.

In addition, described housing 1 and cover plate 5 are shaped by transparent plastic, help the clear tight lock situation of seeing locked inside of user, in time find to get rid of potential safety hazard because assembly damages or misoperation causes tight lock bad.

A kind of novel plastics lock-seal of the present utility model, simple in structure, safe and reliable, can be extensively as the blockade instrument of electrical metering facility or other facility.
