Abstract

The utility model relates to an electricity meter box, more specifically an electricity meter box comprising a cover and a base. The utility model comprises a cover and a base, the central position of the cover is equipped with a screw of sealing meter, the base is equipped with a locker of the screw of sealing meter. The locker of the screw of sealing meter is divided into two parts including a locking part and a fixing part, the locking part is coordinated with the screw of sealing meter in locking situation, the fixing part is positioned on the base, the locking part is relatively suspended above the base, and the fixing part is eccentric to the locking part and the screw of sealing meter. The utility model has the simple and reasonable structure design, the original locker of the screw of sealing meter is divided into two parts, one part is the locking part remained in the original position and the other part is moved downward to form the fixing part, thereby ensuring not only the screw of sealing meter being located in the central location of the cover, the fixing part not interfering with the incoming line of the electricity meter, and but also the firm structure on the locker of the screw of the sealing meter, as well as promoting the anti-electricity-theft ability of the electricity meter box.

Description

Ammeter box

Technical field

The utility model relates to a kind of ammeter box, specifically relates to a kind of ammeter box that is made of face shield and base.

Background technology

The applicant applied for a plurality of ammeter boxes that are made of face shield and base, after covering on base, realizes by face shield the locking of face shield and base by envelope table screw, prevent stealing, envelope table screw generally all is located on the middle position of face shield at present, can make the face shield periphery stressed evenly like this, the envelope table screw lock of using with envelope table screw lock fit then is a cylinder, the top of cylinder is provided with internal thread and cooperates with envelope table screw, in order to guarantee that envelope table screw is positioned at the middle position of face shield, the also corresponding middle position that is located at base of envelope table screw lock then, and the inlet wire that envelope table screw lock can the overslaugh ammeter is set like this.By being to have occurred an a kind of like this ammeter box that envelope table screw lock and envelope table screw are moved toward the next door on the market, though having solved the ammeter inlet wire, this makes things convenient for problem, but because envelope table screw has moved toward the next door, the result can cause another side of face shield easily to pry open anti-electricity-theft ability.

Summary of the invention

Therefore, the purpose of this utility model ammeter box that is to provide a kind of anti-electricity-theft ability height and do not influence ammeter inlet wire problem.

The purpose of this utility model is achieved in that

A kind of ammeter box, comprise face shield and base, the middle position of face shield is provided with envelope table screw, base is provided with envelope table screw lock, described envelope table screw lock is divided into locking bit and fixed bit two parts, locking bit and envelope table screw lock fit, and fixed bit is located on the base, the relative base of locking bit is unsettled, and fixed bit is partial to locking bit and envelope table screw.

Above-mentioned purpose also can be done further perfect by the following technical programs:

Described fixed bit is two cylinders, and two cylinders are being positioned on the substructure height direction position below the locking bit, is triangular shape between two cylinders and the locking bit and arranges and be connected by connecting rod.

Described fixed bit is a cylinder, and cylinder is being positioned on the substructure height direction position below the locking bit, is connected by connecting rod between cylinder and the locking bit.

Described locking bit is a nut.

The utility model structural design advantages of simple, untouched table screw lock separated into two parts, a part is for staying the locking bit of original position, another part down moves the formation fixed bit, has so both guaranteed that envelope table screw also is provided in a side of the middle position of face shield, the inlet wire that fixed bit again can the overslaugh ammeter, the structure of envelope table screw lock is also firm, improve the anti-electricity-theft ability of ammeter box, and had at ammeter box under the situation of equal volume, the utlity model has bigger ammeter installing space.

Fig. 2 is the understructure synoptic diagram of present embodiment 2;

The outside drawing of Fig. 3 ammeter box;

Fig. 4 is the structure cut-open view of envelope table screw and locking bit cooperation.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment 1, in conjunction with Fig. 1, Fig. 3 and Fig. 4, a kind of ammeter box, comprise face shield 1 and base 2, the middle position of face shield 1 is provided with envelope table screw 3, base 2 is provided with envelope table screw lock 4, described envelope table screw lock 4 is divided into locking bit 5 and fixed bit 6 two parts, locking bit 5 is nut and envelope table screw 3 lock fit, locking bit 5 relative bases 2 are unsettled, fixed bit 6 is two cylinders, and two cylinders are being positioned at below the locking bit and are erecting on base on the substructure height direction position, is triangular shape between two cylinders and the locking bit and arranges and be connected by connecting rod 7.Can pass through integrated injection molding between two cylinders, three connecting rods and the locking bit.

Envelope table screw once is described below again, envelope table screw 3 specifically comprises lock body 8, envelope table post 9, envelope table lid 10 and screw 11, face shield is provided with a pit 12,8 of lock bodies are located in the pit 12,9 on envelope table post is located in the ccontaining cavity of lock body 8, envelope table post 9 is provided with screw hole one to one with lock body 8 bottom surfaces, by screw 11 locking bit 5 on envelope table post 9 and lock body 8 and the base is tightened together, and realizes the fastening of face shield and base.

Embodiment 2, and in conjunction with Fig. 2, embodiment 2 is that with the difference of embodiment 1 fixed bit 6 is a cylinder, and 5 of locking bits are unsettled on base by this root cylinder.
