Abstract

The utility model provides a theftproof locking piece of ammeter case relates to ammeter case device field. Including base, lock and catch, the base is the platykurtic, and the locating hole that has the symmetry is opened at both ends about it, the lock sets up in base middle section and upwards protruding, and the one end of this lock upper surface is provided with the catch, and the other end is opened there is the screw, and fixed mounting has the copper nut in the screw. The utility model discloses a screw through installing the tool to lock on the catch, is installed simultaneously to the theftproof locking piece in the screw, it is tight to have carried out double -locking to the case lid of ammeter case, difficultly opens by force, has played good theftproof effect. Simultaneously, it is separable between locking piece and ammeter case, be convenient for regular maintenance and change.

Description

A kind of antitheft lock dog of ammeter box

Technical field

This utility model relates to electricity meter box device field, is specifically related to the antitheft lock dog of a kind of ammeter box.

Background technology

Along with people's being stepped up electricity needs, the electricity expense that people pay also is being stepped up.In the face of the electricity expense use risen steadily, some user may pry open ammeter box with carrying out by every possible means carry out stealing.

The lockhole adopted in existing ammeter box, is only respectively arranged with the lockhole of ring-type at the joint of case lid Yu casing, then penetrates in ring by lock accordingly, reaches the purpose of ammeter box cover locking.This type of lockhole has certain defect, only carries out locking and antitheft by a lock, and anti-theft effect is general；And lockhole also easily cut off by illegal user intentionally, open ammeter chamber door by force, and the coupled case lid of lockhole or casing often integrated molding.After lockhole is cut off, it is necessary to changing whole case lid or casing, not only replacement cost is high, bring bigger economic loss to power department, and change also complexity very.

Utility model content

The technical problems to be solved in the utility model is to provide and a kind of can carry out multi-locking mode simultaneously and change the theftproof lock loop device of convenient ammeter box.

The technical scheme that this utility model adopts is:

A kind of antitheft lock dog of ammeter box, it is characterised in that: including base, lock and lock ring, described base is flat, and two ends have the hole, location of symmetry around；Described lock is arranged at base stage casing and raises up, and one end of this lock upper surface is provided with described lock ring, and the other end has screw, is installed with copper nut in screw.

What described base, lock and lock ring all adopted is hard PC plastics, and integrated injection molding.

Described copper nut is embedded annular knurl copper nut, and with described lock in the lump injection mo(u)lding, make molding and its interior copper nut is installed does not come off.

Technique effect of the present utility model is as follows:

1, by installing lockset on lock ring, screw is installed simultaneously in screw, the case lid of ammeter box has been carried out double locking, has not easily opened by force, served good anti-theft effect；

2, separable between lock dog and ammeter box, it is simple to regular maintenance and replacing.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Illustrate: 1-base, 2-lock, 3-lock ring, 4-position hole, 5-screw, 6-copper nut.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.

The antitheft lock dog of ammeter box as depicted, include base (1), lock (2) and lock ring (3), what adopted is clear hard PC plastics, and each through mould integrated injection molding, makes lock dog have higher structural strength.

As it is shown in figure 1, the base of this lock dog (1) is in flat, two ends have the hole, location (4) of symmetry around, by installing set screw in this hole, location (4), make lock dog be fixedly mounted in the corresponding position of electric meter box body.

Base (1) stage casing raises up rectangular-blocklike, forms lock (2).One end of this lock (2) upper surface is provided with raising up in the form of a ring, form lock ring (3), after lock dog is fixedly mounted in ammeter box, this lock ring (3) is upward through the case lid surface of ammeter box to case lid, after corresponding lockset is installed at lock ring (3) place, the case lid of ammeter box and casing can be locked.

The other end of lock (2) lock ring (3) relatively, also has screw (5), is installed with embedded annular knurl copper nut (6) in screw (5).And with lock (2) injection mo(u)lding in the lump, make molding and its interior copper nut (6) is installed does not come off.After lock dog is fixedly mounted in ammeter box, case lid surface correspondence screw (5) of ammeter box need to have corresponding hole, and from then on hole is screwed into corresponding screw, the case lid of ammeter box and casing is connected by screw, makes the two lock further.Meanwhile, for making the screw being screwed in screw (5) to be unscrewed easily, the full dog point socket set that screw head decorative pattern can be adopted to be abnormity, when not having corresponding screwdriver, screw will not be unscrewed easily.

By installing lockset on lock ring (3), screw is installed simultaneously in screw (5), the case lid of ammeter box has been carried out double locking, has not easily opened by force, served good anti-theft effect.Meanwhile, separable between lock dog and ammeter box, it is simple to regular maintenance and replacing.

The above only have expressed preferred implementation of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation, improvement and replacement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
