Abstract
The utility model provides a kind of integral type lead seal structure, comprise upper cover and two bayonet sockets, described upper cover and two bayonet sockets integrally formed, by upper cover and bayonet socket integrally formed, what solve that existing technique split-type structural failure welding causes affects the problems such as life-span, arrange two bayonet sockets and solve the large and problem of easy fracture of multiple bayonet socket internal stress, and integrally formed structure generation process is simple, thus improve production efficiency, reduce production cost; And by arranging a groove inside upper cover, between two bayonet sockets, the junction thickness of upper cover and two bayonet sockets is 2.8 ~ 3.2mm, makes this lead sealing stability high, solves upper cover and bayonet socket boundary in process of production and the problem such as easily to break, the bad problem of effective improvement, increases life of product.
Description
Technical field
The utility model relates to the integral type lead seal structure of electric energy meter encapsulation field, particularly electric energy meter.
Background technology
After lead sealing refers to that metering appliance detecting is qualified, the equipment being similar to snap close applied by testing person.Such as in order to prevent user from privately taking electric energy meter apart, be connected with the blockade of lead sealing screw with lead sealing between electric energy meter upper cover with lower box body, lead sealing is once correctly locking, unless adopted violence damage lead sealing otherwise cannot open, lead sealing after destroyed cannot be reused, and at present electrical network electric energy meter robotization lead sealing design and be assembled in enterprise practical production run and encountered some technological problemses, such as lead seal structure is split-type structural, and the bayonet socket of 3 or more is set, part is too much, causes installing the problems such as loaded down with trivial details, production cost is too high, easy fracture is bad.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of integral type lead seal structure simplifying production technology, reduction production cost, life-span length.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of integral type lead seal structure, comprises upper cover and is located at two bayonet sockets of upper cover both sides respectively, described upper cover and two bayonet sockets integrally formed.
Upper cover and two bayonet sockets integrally formed, what solve that existing technique split-type structural failure welding causes affects the problems such as life-span, two bayonet sockets are set and solve multiple bayonet socket internal stress problem of easy fracture greatly, and integrally formed structure generation process is simple, thus improve production efficiency.
Preferably, arrange a groove inside described upper cover, between two bayonet sockets, described recess width equals two bayonet socket inner distance.Solve upper cover and bayonet socket boundary in process of production and the problem such as easily to break, effectively improve bad problem, increase life of product.
The junction thickness of described upper cover and two bayonet sockets is 2.8 ~ 3.2mm.This junction thickness is the distance of bottom portion of groove to bayonet socket cheicers place, through experimental verification, when this thickness is 2.8 ~ 3.2mm, and its lead seal structure optimal stability, thus add the life-span of lead sealing.
This lead sealing coordinates conventional lead sealing screw to use, and for blocking lower casing on electric energy meter, prevents user from privately dismantling.
Compared with prior art, the utility model tool has the following advantages:
The utility model provides a kind of integral type lead seal structure, by upper cover and bayonet socket integrally formed, what solve that existing technique split-type structural failure welding causes affects the problems such as life-span, two bayonet sockets are set and solve multiple bayonet socket internal stress problem of easy fracture greatly, and integrally formed structure generation process is simple, thus improve production efficiency, reduce production cost; And by arranging a groove bottom upper cover, between two bayonet sockets, the junction thickness of upper cover and two bayonet sockets is 2.8 ~ 3.2mm, makes this lead sealing stability high, solves upper cover and bayonet socket boundary in process of production and the problem such as easily to break, the bad problem of effective improvement, increases life of product.
Accompanying drawing explanation
Fig. 1 is the utility model integral type lead seal structure perspective view;
Fig. 2 is the utility model integral type lead seal structure front elevation;
Fig. 3 is the using state reference diagram of the utility model integral type lead seal structure;
Fig. 4 is that the using state of the utility model integral type lead seal structure is with reference to sectional view;
Fig. 5 is R-portion partial enlarged drawing in Fig. 4.
Embodiment
The utility model to be explained in further detail below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that.
As shown in Figure 1, 2, a kind of integral type lead seal structure, comprises upper cover 1 and is located at two bayonet sockets 2 of upper cover 1 both sides respectively, upper cover 1 and bayonet socket 2 integrally formed, described bayonet socket 2 is internal fastening type bayonet socket.Inside upper cover 1, between two bayonet sockets 2, arrange a groove 3, this groove 3 is rectangular recess, and described groove 3 width equals two bayonet socket 2 inner distance, and described bottom portion of groove is 3.0mm to bayonet socket cheicers place thickness H.
As shown in Fig. 3,4,5, this lead sealing coordinates conventional lead sealing screw 4 to use, and for blocking shell 5 and lower casing 6 on electric energy meter, prevents user from privately dismantling.During use, first by the shell 5 and the lower casing 6 that install electric energy meter, lead sealing screw 4 is arranged in the slotted eye of shell 5 and lower casing 6 correspondence position, then by artificial or machinery, integral type lead sealing is pressed in electric energy meter upper casing corresponding slot, thus the bayonet socket 2 of integral type lead sealing snaps in the ring groove of lead sealing screw 4, reach the object of blocking lower casing on electric energy meter.
Integral type lead seal structure described in the present embodiment, by upper cover 1 and bayonet socket 2 integrally formed, what solve that existing technique split-type structural failure welding causes affects the problems such as life-span, two bayonet sockets 2 are set and solve multiple bayonet socket internal stress problem of easy fracture greatly, and integrally formed structure generation process is simple, thus improve production efficiency; And by arranging a groove 3 inside upper cover 1, between two bayonet sockets 2, the inside and outside bottom of bayonet socket is made to form certain difference in height, thus to make bottom bayonet socket not easy fracture, the junction H thickness of upper cover 1 and two bayonet sockets 2 is 3.0mm, makes the thickness of bayonet socket and upper cover junction H be in optimum dimension, the most firmly, thus this lead sealing stability is higher, solve upper cover and bayonet socket boundary in process of production and the problem such as easily to break, effectively improve bad problem, increase life of product.
In the utility model, the not concrete functional module introduced all can adopt ripe functional module of the prior art, such as lead sealing screw.
Be more than wherein specific implementation of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the 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, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
