Abstract
The utility model provides an electric energy meter sealing structure, comprising a seal body and a plug-in unit matched with the seal body; and two sides in the seal body are provided with clamping positions, and two sides of the plug-in unit are provided with plastic elastic arms matched with the clamping positions. After the plug-in unit is plugged into the seal body, the plastic elastic arms of the plug-in unit are clamped at the clamping positions at the two sides of the seal body, and as the plug-in unit is baffled by the clamping positions, the plug-in unit can not be withdrawn from the seal body; and if the plug-in unit is forcibly withdrawn from the seal body, the plastic elastic arms can be broken off. Due to an internal fixing mode, the electric energy meter sealing structure can effectively prevent from being prized up, and is simple in structure, and convenient to install.
Description
Technical field
The utility model relates to electric energy meter, in particular for the seal of electric energy meter.
Background technology
The seal of electric energy meter, long-term in the past use lead sealing, the weak point of this lead sealing is that the frequent contacting metal of staff is plumbous, causes saturnism easily.This kind seal mode complicated operation in addition is unfavorable for the high efficiency production of robotization; The general volume of this lead seal structure is bigger, and quality is heavy; And lead sealing is pried open easily.
Summary of the invention
The utility model technical matters to be solved provides a kind of electric energy meter seal structure, and is simple in structure, and security performance is good, and volume is little, and is in light weight.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of electric energy meter seal structure comprises envelope body and the plug-in unit that is mated; Both sides are provided with screens in the said envelope body, and said plug-in unit both sides are provided with the plastic cement elastic arm with said clamping matching.Plug-in unit inserts Feng Tihou, and the plastic cement elastic arm of plug-in unit is stuck in screens place of envelope body both sides, because plug-in unit receives stopping of screens and can't withdraw from the envelope body; If by force plug-in unit is withdrawed from the envelope body, then the plastic cement elastic arm can fracture, and this internal fixation mode can effectively prevent to be pried open, and simple in structure, easy for installation.
As improvement, said screens and said envelope body by integral forming.The envelope body is through the incorporate mould injection molded that tiltedly ejects, make envelope body periphery as none Feng Tichang the forming technology hole is arranged, fundamentally stop electricity filching person plan through envelope body technology hole pry open seal maybe.
As improvement, said plastic cement elastic arm comprises holding section and arc connecting portion, and said holding section is connected with said plug-in unit front end through the arc connecting portion.Because the front end of plastic cement elastic arm is the connecting portion of arc, when plug-in unit gets into the envelope body, reduces the resistance that the plastic cement elastic arm gets into, thereby make plug-in unit can enter into Feng Tizhong smoothly.
As improvement, said plug-in unit is provided with the through wires hole that runs through the upper and lower surface of plug-in unit.The installation form of envelope table line has two kinds: one, at first envelope is shown line and pass the sealing hole on the envelope body, then plug-in unit is advanced, utilize plug-in unit to live envelope table ply-yarn drill; Do not adorn envelope table line in advance, leave the user for and install voluntarily as required, during installation, only need the through wires hole on the plug-in unit be aimed at the sealing hole on the envelope body, then envelope is shown line and pass; At last plug-in unit is pushed in the envelope body and get final product.
As improvement, the upper and lower surface of said plug-in unit is provided with the shape of threads rib.Adopt the shape of threads rib tight envelope table line pressure.
The beneficial effect that the utility model is compared with prior art brought is:
Plug-in unit inserts Feng Tihou, and the plastic cement elastic arm of plug-in unit is stuck in screens place of envelope body both sides, because plug-in unit receives stopping of screens and can't withdraw from the envelope body; If by force plug-in unit is withdrawed from the envelope body, then the plastic cement elastic arm can fracture, and this internal fixation mode can effectively prevent to be pried open, and simple in structure, easy for installation;
Said plug-in unit is provided with the through wires hole that runs through the upper and lower surface of plug-in unit.Can not adorn envelope table line in advance during production, leave the user for and install voluntarily as required, during installation, only need the through wires hole on the plug-in unit be aimed at the sealing hole on the envelope body, then envelope is shown line and pass; At last plug-in unit is pushed in the envelope body and get final product.

Embodiment
Below in conjunction with Figure of description the utility model is described further.
Shown in Fig. 1 to 3, a kind of electric energy meter seal structure comprises envelope body 1 and the plug-in unit 2 that is mated.Both sides are provided with screens 10 in the said envelope body 1; Said screens 10 and said envelope body 1 are one-body molded; Envelope body 1 is through the incorporate mould injection molded that tiltedly ejects; Make envelope body 1 periphery as none envelope body 1 the forming technology hole is often arranged, fundamentally stop electricity filching person plan through envelope body 1 fabrication hole pry open seal maybe.The upper and lower surface of said envelope body 1 front end is provided with corresponding sealing hole 4, supplies envelope table line 3 to pass through.Like Fig. 4, shown in 5, said plug-in unit 2 both sides are provided with the plastic cement elastic arm 7 that cooperates with said screens 10, and said plastic cement elastic arm 7 comprises holding section 8 and arc connecting portion 9, and said holding section 8 is connected with said plug-in unit 2 front ends through arc connecting portion 9.Because the front end of plastic cement elastic arm 7 is the connecting portion 9 of arc, when plug-in unit 2 gets into envelope body 1, reduces the resistance that plastic cement elastic arm 7 gets into, thereby make plug-in unit 2 can enter into envelope body 1 smoothly.Said plug-in unit 2 is provided with the through wires hole 5 that runs through plug-in unit 2 upper and lower surfaces, makes the installation form of envelope table line 3 that two kinds of forms arranged: one, at first envelope is shown line 3 and pass the sealing hole 4 on the envelope body 1, then plug-in unit 2 is advanced, utilize plug-in unit 2 to block envelope table line 3; Do not adorn envelope table line 3 in advance, leave the user for and install voluntarily as required, during installation, only need the through wires hole on the plug-in unit 25 be aimed at the sealing hole 4 on the envelope body 1, then envelope is shown line 3 and pass; At last plug-in unit 2 is pushed in the envelope body 1 and get final product.Said plug-in unit 2 upper and lower surfaces are provided with shape of threads rib 6, and plug-in unit 2 is fixed envelope table line 3 under the effect of shape of threads rib 6 after inserting envelope body 1.
After plug-in unit 2 inserted envelope body 1, the plastic cement elastic arm 7 of plug-in unit 2 was stuck in screens 10 places of envelope body 1 both sides, can't withdraw from envelope body 1 because plug-in unit 2 receives stopping of screens 10; If by force plug-in unit 2 is withdrawed from envelope body 1, then plastic cement elastic arm 7 can fracture, and this internal fixation mode can effectively prevent to be pried open, and simple in structure, easy for installation.
