Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
In describing the invention, it will be appreciated that, term " on ", D score, "front", "rear", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention and simplifies description, rather than instruction or hint indication device or element must have specific orientation, with specific azimuth configuration and operation, be therefore not considered as limiting the invention.
In describing the invention, it should be noted that unless otherwise clearly defined and limited, term " is installed ", " being connected ", " connection " should be interpreted broadly, and connects for example, it may be fixing, is integrally connected, it is also possible to be to removably connect；It can be the connection of two element internals；Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary, for the ordinary skill in the art, above-mentioned term concrete meaning in the present invention can be understood with concrete condition.
Fig. 1 show the structural representation in the present embodiment detection device of electric energy meter front.This detection device of electric energy meter includes carrying body 10, is provided with containing cavity 20 on this carrying body 10, and this containing cavity 20 is for accommodating electric energy meter to be detected.As preferably, the edge of this containing cavity 20 is provided with at least one locating slot 21, is 3 locating slots 21 in the present embodiment.During electric energy meter to be detected is inserted containing cavity 20, locating slot 21 plays the role of positioning.
Further, being provided with some plug assemblys 30 for carrying electric energy meter current lead-out terminal in its containing cavity 20, the arrangement of this plug assembly 30 electric energy meter with distribution with for detection is corresponding.In the present embodiment, 6 plug assemblys 30 are distributed in 2 rows, and between 2 rows symmetrically, every package includes 3 plug assemblys.Certainly, this kind of distribution form is only a kind of optimized choice of the present embodiment, the not restriction to distribution form, and concrete distribution form is corresponding with the electric energy meter needing detection.
As the improvement of the present embodiment, as Figure 1-4, above-mentioned plug assembly 30 at least includes fixing tongue 32, movable tongue 31 and drive mechanism 40.Wherein fixing tongue 32 is fixing with carrying body 10 is connected, hinged by jointed shaft 35 between movable tongue 31 and fixing tongue 32, forms the grafting chamber 33 for accommodating electric energy meter current lead-out terminal between front end and the fixing tongue 32 of movable tongue 31.
Further, the drive mechanism 40 in the present embodiment includes drive shaft 43, drives motor 41, eccentric 42, position sensor 44 and push rod 34.The outfan of motor 41 is wherein driven to be connected with drive shaft 43, eccentric 42 is fixedly connected in drive shaft 43, the outline of the end of push rod 34 and eccentric 42 is abutted against, and position sensor 44 is for controlling the anglec of rotation of drive shaft 43, and the tail end linkage of push rod 34 and movable tongue 31.It should be noted that push rod 34 is corresponding with the row of plug assembly 30 with the quantity of eccentric 42, in the present embodiment, including 2 socket connection devices 30, correspondingly, push rod 34 and eccentric 42 are equipped with 2.
As preferably, all fixing tongue 32 being equipped with the pilot hole 37 adapted with push rod 34, push rod 34 is passed by the pilot hole 37 in same row's fixing tongue 32.Tail end at its movable tongue 31 is then provided with the chute 38 adapted with push rod 34, and push rod 34 again passes through the chute 38 on same row's movable tongue 31.Its push rod 34 is additionally provided with bearing pin 39, the quantity of this bearing pin 39 and position and movable tongue 31 one_to_one corresponding, and movable tongue 31 contacts with bearing pin 39 holding.
Further, being provided with elastic mechanism 36 between its movable tongue 31 and fixing tongue 32, as preferably, elastic mechanism 36 is the compression spring between jointed shaft 35 and push rod 34.
The detection device of electric energy meter of the present embodiment, under original state, push rod contacts with outline at the least radius of eccentric, and now the grafting chamber between movable tongue and fixing tongue is in closure state.When needing to insert electric energy meter to be detected, start and drive motor, by driving motor to drive drive shaft to rotate, and then band movable eccentric wheel rotates, in eccentric rotary course, push rod moves at the least radius of eccentric with the contact position of eccentric outline at maximum radius, drive push rod transverse shifting, and then promoted movable tongue to rotate around jointed shaft by bearing pin so that grafting chamber is opened, allowing that the current output terminal of electric energy meter inserts, now elastic mechanism is in compressive state.It should be noted that when the profile that eccentric rotates to maximum radius contacts with push rod, position sensor send signal, drive motor out of service, make grafting chamber be in open mode.After electric energy meter has detected, starting motor reversal, push rod, under the restoring force effect of elastic mechanism, remains with the outline of eccentric and contacts.When eccentric rotates to original state, position sensor sends signal, drives motor out of service.Above-mentioned detection process is gone round and begun again, and can complete the batch detection of electric energy meter.
In a word, the foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
