Description
Technical field
The utility model relates to electric power meter, is specifically related to the casing of table case in the electric power meter and the hook snap type buckle structure between the case lid.
Background technology
The resident's power supply and the industrial or agricultural electric power system distributed areas of China are huge, the terminal of electric power system--electric power meter, spread all in each family and all kinds of industrial and mining enterprises in vast town and country, because the backwardness of the protective equipment of existing electric power meter, the phenomenon that theft State Grid resource is escaped the electricity charge happens occasionally.
Electric power meter is to be made of electric energy meter, casing, case lid, and electric energy meter is arranged in the casing, covers the case lid encapsulation on the casing again.In order to prevent stealing, also for safety, power supply department encapsulates with the mode that fine rule adds lead sealing between casing and case lid, opens the stealing of table case privately to forbid the user.Though this packaged type is opened electric power meter to the user and is provided with obstacle, but after still can melting lead sealing, the user that instrument is arranged opens case lid, covering case lid again after then electric energy meter being juggled things seals lead sealing again to original state, difficult discovery when power supply administration tables look-up like this is unfavorable for that power supply department carries out the electricity consumption supervision.
Summary of the invention
The case lid that the utility model exists at prior art opens that the back lead sealing can restore to the original state, power-steeling preventing effect is poor, be unfavorable for that power supply department carries out the technical matters of electricity consumption supervision, and a kind of novel hook snap type buckle structure that is exclusively used in case lid and casing in the locking electric power meter is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hook snap type buckle structure of electric power meter, in the casing and case lid of electric power meter, one are provided with embedded hole, another person goes up correspondence and is provided with button bit, run through towards button bit in the described embedded hole and be embedded with a barb element, this barb element by extend on the fixture block of root and the fixture block and pass through embedded hole about two barb arm constitute, the root of described fixture block or two barb arm is provided with the step that stops with embedded hole aperture contact matching; Described two barb arm left-right symmetric, its head is provided with the barb on tape guide inclined-plane laterally, and two barbs] head be connected with horizontal stroke between extreme]; Described button bit mainly constitutes with right button piece by detain piece at a distance of a left side that is provided with, and the room that forms between piece and the right side button piece for the head embedding of barb element is detained on a left side; During locking, the head of described barb element embeds in the button bit, and the left side barb cooperates with left side button piece, and the right side barb cooperates with right button piece, constitutes the hook snap type buckle structure with this.
Related content in the technique scheme is explained as follows:
1, in the such scheme, further be preferably: between the stage casing of two barb arm, connect a bending support bar, increase the intensity of two barb arm with this bending support bar, make people on the barb arm stage casing, apply the external force tilting with instrument, also can't make barb deviate from button bit and unblank, further improve this buckle structure locking fastness.But various forms bendings such as the shape triangle of described bending support bar, S shape, but the best is a S shape.
2, in the such scheme, there are two kinds of situations the position that is provided with of described embedded hole and button bit: the one, and embedded hole is arranged on the casing, and button bit is arranged on the case lid, is about to barb element and is embedded on the casing from bottom to top, when closing case lid, the button bit of case lid is fastened on the barb of barb element again and locks; The 2nd, reverse installation is arranged at embedded hole on the case lid, and button bit is arranged on the casing, is about to barb element and is embedded in from the top down on the case lid, when closing case lid, pushes the barb element on the case lid, and the button bit that its barb is snapped on the casing locks.
Further again: as can need not to hold barb element, barb element when closing case lid and can not roll fixing by screw is auxiliary between the wall of the fixture block of barb element and casing, making, make more convenient operation.
3, in the such scheme, described barb element can adopt engineering plastics to make, and guarantees that barb arm has a point elasticity to get final product.
4, in the such scheme, the head of described " between the head of two barb arm is extreme " two barb arm here extremely is meant the head meaning foremost of barb arm, is the place, edge foremost of head.
5, in the such scheme, in the described button bit, left side button piece is provided with guide surface with right the button on the piece inboard corresponding to the guiding surface on the barb, so that the head of barb element can more successfully embed in the button bit.
Design concept of the present utility model: the utility model adopts barb element that the casing and the case lid of electric power meter are fixed locking, because of being overhead structure, promptly can't withdraw from after snapping in locking, and case lid was opened in the ability release after a useful tool was cut off barb arm.It locks main element--and barb element is then only supplied with the specialized maintenance personnel of power supply department as parts peculiar.Therefore, used this buckle structure, after the user opens case lid privately, can't recover, known at a glance when power supply department is tabled look-up whether case lid was opened, be convenient to power supply department and carry out the electricity consumption supervision.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
Because employing barb element of the present utility model locks casing and case lid, after in a single day barb element snaps in locking, promptly can't release, have only the failure mode by cutting off barb arm could release, prevent that effectively the stealing personnel from opening case lid and touching electric energy meter; After the stealing personnel destroy barb element case lid is opened, its barb element is irrecoverable, and power supply department is known when tabling look-up at a glance, has made things convenient for the electricity consumption supervision.
