Abstract
The utility model relates to a kind of electric energy measuring equipment seal cap, comprising: back-off, retainer, block; Back-off is evenly distributed on inside retainer; Block is uniformly distributed and is connected to bottom retainer.This seal cap adopts injection molding manner one-body molded, this seal cap is installed on the trip bolt of electric energy meter, provide a kind of new and effective, convenient, reliable seal mode, thus improve production efficiency, also can prevent access by unauthorized persons from opening table cover and touching electric energy meter inside.
Description
Technical field
The utility model relates to a kind of seal cap, particularly relates to a kind of electric energy measuring equipment seal cap.
Background technology
Traditional seal mode adopts threading type lead sealing, or the seal mode be made up of trip bolt, clip, seal cap, complicated with upper type operating procedure, is difficult to realize modern industry automated production.Therefore, a kind of new and effective, convenient, reliable seal cap of design is enhanced productivity is necessary.
Utility model content
The utility model is overcome above-mentioned weak point, object is to provide a kind of electric energy metering seal cap, this seal cap adopts injection molding manner one-body molded, and this seal cap is installed on the trip bolt of electric energy meter, prevents access by unauthorized persons from opening table cover and touching electric energy meter inside.
The utility model achieves the above object by the following technical programs: a kind of electric energy measuring equipment seal cap, comprising: back-off, retainer, block; Back-off is evenly distributed on inside retainer; Block is uniformly distributed and is connected to bottom retainer.
As preferably, described back-off has three lobes; Retainer has three lobes.
As preferably, the spacing of described adjacent retainer is 0.5mm; Retainer is to bottom withdrawing pattern 1 °, and withdrawing pattern height 6mm, thickness is 1.23mm, bottom margin chamfering 0.8mm.
As preferably, the diameter 11mm of described block, extension boss height 3mm.
As preferably, described back-off has elasticity, and back-off end face is of a size of 4mm apart from seal cap bottommost.
As preferably, described electric energy measuring equipment seal cap adopts injection molding manner one-body molded.
The beneficial effects of the utility model are: (1) this seal cap provides a kind of new and effective, convenient, reliable seal mode, thus improves production efficiency; (2) this seal cap can prevent access by unauthorized persons from opening table cover and touching electric energy meter inside.
Accompanying drawing explanation
Fig. 1 is the utility model seal cap three-dimensional plot;
Fig. 2 is the utility model seal cap dimensional drawing;
Fig. 3 is that the utility model seal cap coordinates figure with trip bolt;
Fig. 4 is the utility model seal cap effect figure.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further, but protection domain of the present utility model is not limited in this:
Embodiment: as shown in Figure 1, a kind of electric energy measuring equipment seal cap, comprising: back-off 1, retainer 2, block 3; Back-off 1 is evenly distributed on inside retainer 2; Block 3 is uniformly distributed and is connected to bottom retainer 2; It adopts injection molding manner one-body molded.
Back-off 1 has three lobes, is distributed on maintenance, and in 2, back-off 1 has certain tension force, and when the head of trip bolt starts to enter back-off 1, back-off 1 outwards opens, and trip bolt is entered in back-off 1 smoothly.When the head of trip bolt enters in back-off 1 completely, because screw intermediate sizes is less than screw head, the elasticity of back-off 1 utilization itself, retracts inwards, reaches fixing effect.
Retainer 2 has three lobes, and be connected with block is uniform, retainer 2 has certain tension force, can ensure that trip bolt is more prone to penetrate in back-off 1, makes back-off 1 not easily should be out of shape comparatively large and fracture; Retainer 2 also plays the connection function of block 3 and back-off 1.
Block seal screw hole, and mark above, information, make access by unauthorized persons not turn on screw.
As shown in Figure 2 be seal cap dimensional drawing, block a shot 3 diameter 11mm, extension boss height 3mm.Retainer 2 full-size diameter is 8.8mm, and to bottom withdrawing pattern 1 °, withdrawing pattern height 6mm, thickness 1.23mm, the gap between adjacent retainer is 0.5mm, bottom margin chamfering 0.8mm.Back-off 1 end face is apart from the bottommost size 4mm of seal cap.
As shown in Figure 3, Figure 4 be the practical application effect figure of seal cap, first seal cap is put in electric energy meter fastening screw nail, then a pressure is applied to seal cap, make the back-off of seal cap be buckled on trip bolt, make it to take out.
This seal cap, without the need to increasing other annex again, utilizes and changes screw head structure, make it to be interconnected, can meet and realize automation production flow line condition.
The know-why being specific embodiment of the utility model and using described in above; if according to the change that conception of the present utility model is done; its function produced do not exceed that instructions and accompanying drawing contain yet spiritual time, protection domain of the present utility model must be belonged to.
