Turntable 35, an internal gear 36 is equipped in each turntable 35, and sliding bar 38 runs through 5 internal gears 36, the side of internal gear 36
It opens up jagged, detent block 37 is equipped in notch, the bottom end fixing assembling of switch lever 33 has sliding bar 38, fills on sliding bar 38
5 identical limited blocks 39 of sliding bar 38 are parallel to, and limited block 39 is located at the right side of turntable 35.
In the utility model, the cipher switch of switch lever 33 and five coded locks 3 of composition of spring 34 rotates turntable 35, when
When password is correct, the notch of internal gear 36 is opposite with 39 position of limited block, to the left toggle switch bar 33, and limited block 39 can move
Into internal gear 36, five coded locks 3 are opened, and front cover 21 can open at this time.
When five 3 input error passwords of coded lock, the notch of internal gear 36 and 39 position of limited block be not opposite, dials to the left
Dynamic switch lever 33, switch lever 33 can not be stirred at this time, and five coded locks 3 are in close state at this time, and front cover 21 is fail to open.
Five coded locks 3 can be with Modify password when there was only in the open state, and limited block 39 jacks up detent when password is correct
Block 37, turntable 35 and internal gear 36 are in separated position, and new password is arranged in rotation turntable 35, and internal gear 36 is fixed at this time,
Switch lever 33 is stirred to the left after setting new password, limited block 39 is not in top detent block 37, and detent block 37 is by turntable at this time
It is resetted after 35 gravity applied, turntable 35 is engaged again with internal gear 36, and setting completed for password at this time, and it is close can to dial random turntable 35
Code, prevents password from revealing.
As shown in Fig. 2, the right side wall of cabinet 2 offers the limited mouth 4 matched with sliding bar 38,2 right inner side wall of cabinet
Upper fixing assembling has vibration induction alarm device 5, and vibration induction alarm device 5 is electrically connected with metering system.
Password error condition lower switch bar 33 is clamped into limited mouth 4, and front cover 21 is fail to open, the correct toggle switch of password
Switch lever 33 is clamped into one end of limited mouth 4 and skids off by bar 33, and front cover 21 can be opened at this time, sets in the right inner side wall of cabinet 2
Vibration alarm is set, when high-voltage electric-energy meter is opened in electricity filching person violence, high-voltage electric-energy meter is generated by violence
Vibration, vibration induction alarm device 5 is vibrated alarm at this time.
Wherein vibration induction alarm device RL-08 can be selected in vibration induction alarm device 5, and certain alarm is not limited to above-mentioned vibration
Innervation answers alarm 5, if can when cabinet 2 is by violent unpacking induction alarm alarm, the utility model mentions
What is supplied is the antitheft metering device using above-mentioned vibration induction alarm device 5.
As shown in Figure 1, the cover of cabinet 2 is got up using insulation dustproof protecting cover 6 equipped with insulation dustproof protecting cover 6 outside cabinet 2
Destruction of the wind and weather to cabinet 2 can be prevented, also there is insulation effect, it is safer.
As shown in figure 4, the shape of internal gear 36 is square, the face diagonal length of internal gear 36 is less than the interior of turntable 35
Diameter, internal gear 36 should be slightly less than turntable 35, if turntable 35 and internal gear 36 can not be separated with the big detent block 37 such as turntable 35,
Password is set to adjust, the internal gear 36 of square can be engaged when five coded locks 3 are closed with turntable 35 more to be agreed with,
When five coded locks 3 are in and open, password is arranged in rotation turntable 35, and the rotation of turntable 35 is more smooth, wherein the shape of internal gear 36
Shape can be modified according to application requirement, but pass through test of many times, and the shape of internal gear 363 agrees with degree more when being square
Good, more stable, the rotation of turntable 35 is more smooth when password is arranged.
The both ends of detent block 37 are hemisphere face, and the width range of detent block 37 is in 1.2mm-2mm.Hemispherical detent block 37
When being that limited block 39 contacts, hemispherical structure suffered resistance when limited block 39 pushes forward is smaller, when password is arranged,
The jack-up of detent block 37 separates internal gear 36 and turntable 35, and turntable 35 is by hemisphere face detent block 37 when rotation turntable 35 changes password
Frictional force it is smaller, wherein the width of detent block 37 is not answered wide, is rubbed through 37 width of test of many times detent block in 1.2mm-2mm
It is minimum to wipe power.
As shown in figure 4, internal gear 36 and the joint end of turntable 35 are separated to ensure that detent block 37 is limited the jack-up of block 39
When, the non-joint end and turntable 35 of internal gear 36 are clamped, and are caused turntable 35 that can not rotate, can not be adjusted and set password, should meet: set card
Position block 37 with a thickness of L, if institute's internal gear 36 is l not at a distance from 35 joint end to turntable of turntable, specifically: L < l.
Working principle: by rotating turntable 35, turntable 35 drives internal gear 36 to adjust notch and the limit of internal gear 36
39 relative position of block, the notch of internal gear 36 is opposite with the position of limited block 39 when only password is correct, five 3 ability of coded lock
It opens, when password is correct, toggle switch bar 33, switch lever 33 drive sliding bar 38 to the left, and the limited block 39 on sliding bar 38 is logical
36 indentation, there of internal gear is crossed, limited block 39 jacks up detent block 37 at this time, and detent block 37 separates turntable 35 and internal gear 36, and five close
Code lock 3 is in the open state, and front cover 21 can be opened, and five coded locks 3 can change password at this time, when five coded locks 3 are defeated
When entering bad password, toggle switch bar 33 to the left, the limited block 39 on sliding bar 38 can not pass through internal gear 36,33 nothing of switch lever
Method is stirred, and five coded locks 3 are in close state at this time, and front cover 21 can not be opened.
A kind of high-voltage electric-energy meter in the embodiment, it is right by installing five coded locks 3 and vibration induction alarm device 5 additional
Electric energy meter carries out duplicate protection, makes electricity filching person that can not easily open electronic box, and installs insulation proofing dust and protecting additional outside cabinet 2
Cover 6, preferably protects high-voltage electric-energy meter.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model rather than to this is practical
The limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, the common skill of this field
Art personnel should be appreciated that can be practical without departing from this with the technical solution of the present invention is modified or equivalently replaced
The spirit and scope of new technique scheme.
