One side of a flip cover (2) is hinged to a first mounting hole (1.2) and a second mounting hole (1.3) which are formed at one side of a shell body (1) through a rotation shaft (2.3) of which two ends are provided with a first hinging cylinder (2.1) and a second hinging cylinder (2.2); the other side of the flip cover (2) is fixed to the shell body (1) through lead seal screws; grooves (1.4) through which the first hinging cylinder (2.1) and the second hinging cylinder (2.2) can be guided into the first mounting hole (1.2) and the second mounting hole (1.3) are formed in at least one of the first mounting hole (1.2) and the second mounting hole (1.3); and the openings of the grooves (1.4) face the cavity (1.1) of the shell body. With the flip cover type electric meter shell and the assembling method thereof provided by the invention adopted, electricity stealing caused by a situation that a user pries off a hinging part at one side of a flip cover without damaging lead seals at the other side of the flip cover can be avoided.
Description
Technical field
The present invention relates to electric energy meter technical field, be specifically related to a kind of turnover type electric energy meter case and assembly method thereof.
Background technology
Electric energy meter is as a kind of metering outfit, metering accuracy is most important, a kind of turnover type electric energy meter in the market, renovates with case side hinged, and opposite side is fixed by lead sealing screw, described hinged side of namely renovating is provided with rotating shaft, articulated cylinder is established at rotating shaft two ends, and shroud body is provided with the mounting hole coordinated with articulated cylinder, and articulated cylinder length is 1.2mm, by external stress, articulated cylinder is snapped in the mounting hole of shroud body.There is drawback in this hinged installation, because articulated cylinder is shorter, when not destroying the lead sealing of renovating opposite side, use external stress easily can pry open hinge point, in direct destruction shroud body cavity, the components and parts of electric energy meter, make electricity walk less even not walk, reach the object of stealing.After electric energy meter stealing, only need snap in case renovating again, from the appearance and do not destroy front striking resemblances, Utilities Electric Co. is difficult to find this kind of electricity filching behavior.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of when not destroying lead and renovating opposite side lead sealing, prevents renovating hinged place, side and is caused by prying open by the turnover type electric energy meter case of stealing and assembly method thereof.
The present invention's adopted technical scheme that solves the problem is: a kind of turnover type electric energy meter case, comprise shroud body, described shroud body is provided with the cavity for accommodating electric energy meter component, described cavity is provided with for covering renovating of cavity, describedly renovate the first mounting hole that side is provided with the side of shroud body respectively by the rotating shaft that two ends are provided with the first articulated cylinder and the second articulated cylinder and the second mounting hole is hinged, the described opposite side renovating opposite side and shroud body is fixed by lead sealing screw, in described first mounting hole and the second mounting hole, at least one is provided with the groove imported for the first articulated cylinder and the second articulated cylinder, described slot opening is towards the cavity of shroud body.
Compared with prior art, the invention has the advantages that: articulated cylinder is lengthened, by described groove, articulated cylinder is pushed mounting hole in cavity, replace original mode by external stress, shorter articulated cylinder being snapped in mounting hole, solve when do not destroy renovate opposite side lead sealing, pry open hinge point, cause by the problem of stealing.
As a modification of the present invention, the length range of described first articulated cylinder and the second articulated cylinder is 2.0mm ~ 3.5mm, and described scope is reasonable in design, meets assembling needs simultaneously.
Preferred as one of the present invention, the length of described first articulated cylinder and the second articulated cylinder is 2.4mm, and described length is the twice of former articulated cylinder length, is most preferably length.
A kind of improvement is also had as of the present invention, described groove is conical socket, namely the depth of section size in described groove and cavity connects face is greater than the diameter dimension of the first articulated cylinder and the second articulated cylinder, the depth of section size of described groove and the first mounting hole and the second mounting hole connected surface is less than the diameter dimension of the first articulated cylinder and the second articulated cylinder, by described improvement, when articulated cylinder is pushed groove, articulated cylinder is by the connected surface interference fit with groove and mounting hole, snap in mounting hole, when preventing from renovating rotation, articulated cylinder skids off groove.
Preferred as one of the present invention, the depth of section size of described groove and the first mounting hole and the second mounting hole connected surface than 0.3mm described in the little 0.3mm of the diameter dimension of the first articulated cylinder and the second articulated cylinder through practical test, neither need too large thrust, can ensure after snapping in that again articulated cylinder can not be deviate from from mounting hole voluntarily.
Preferred as one of the present invention, the quantity of described groove is one, and described groove is located at the first mounting hole place, and countershaft when rotating shaft rotates that is engaged in of the second articulated cylinder and the second mounting hole does circumference constraint, a groove is simpler, easy to process than two groove structures simultaneously.
The present invention also has a kind of assembly method of turnover type electric energy meter case, and described turnover type electric energy meter case assembling is through following steps:
A, axially inserts the second articulated cylinder renovating rotating shaft in the second mounting hole of shroud body along the second mounting hole;
B, pushes the first mounting hole of shroud body after renovating rotating shaft first articulated cylinder alignment indentation in cavity;
C, will renovate after opposite side buckles into shroud body opposite side, and fix, then buckle lead sealing cap with lead sealing screw.
Compared with prior art, the advantage of this method is: described second articulated cylinder diameter is less than the second mounting hole diameter, first the second articulated cylinder is inserted in the second mounting hole, described first mounting hole be provided with one consistent with its degree of depth, along the groove that the cavity direction of shroud body is offered, described groove 0.3mm less of than the diameter of the first articulated cylinder the width of the first mounting hole connected surface, laterally push in the first mounting hole by after the first articulated cylinder alignment indentation of renovating rotating shaft, finally will renovate opposite side and buckle into shroud body opposite side, lead sealing cap is buckled into after fixing with lead sealing screw, whole assembling process is simple, solve in former design the problem needing to be clamp-oned by articulated cylinder by certain external stress mounting hole, described articulated cylinder length of renovating rotating shaft two ends is 2.4mm, for the twice of former design length 1.2mm, articulated cylinder normally cannot prize from mounting hole after mounting, if brute force prizes, the articulated cylinder that can break words shroud body or renovate, Utilities Electric Co. is very easy to find the situation of stealing, thus reach the object of pick-proof.
