Description
Technical field
The utility model relates to a kind of handle lock of circuit breaker, belongs to breaker technical field.
Background technology
Circuit breaker to be used in distribution line and to be realize on/off switch by the operation of handle.In the use procedure of circuit breaker, in order to prevent circuit breaker by misoperation absent-mindedly, the life security of attendant is affected when affecting switching electricity situation or circuit maintenance, bring unpredictalbe consequence, the position of circuit breaker handle is relatively fixed on separating brake or closing position, makes it not be misused and just seem particularly important.Therefore, when circuit is using or needing maintaining, maintenance, handle lock device can used to install on-board the circuit breaker as a kind of external accessory, be used for fixing handle of stopping, prevent because others causes damage to the misoperation of circuit breaker.
Current handle lock, some needs additional processing installing hole or mounting groove on-board the circuit breaker, but due to the design volume of circuit breaker more and more less, contour structures is also tending towards simplifying, and it is very difficult that the product for small size additionally will increase that hole or groove just become.Some handle lock will lean on the combination of multiple part to realize the locking of different conditions, and the part coordinated after unlocking will be removed, and may lose, not only increase cost, and structure is loaded down with trivial details when reusing.Also have other handle lock, this body structure is comparatively complicated, production and processing complex steps, and materials are more, and structural strength is not high, and there is the defect of installing inconvenience.
Utility model content
Therefore, the technical problems to be solved in the utility model is to overcome defect of the prior art, and provide a kind of structure simple, parts are few, and volume is little, and the handle lock of the high circuit breaker of structural strength.
To achieve these goals, the handle lock of a kind of circuit breaker of the present utility model, comprise fixed support and be arranged on the clamp on fixed support by rotating shaft mechanism, at described fixed support, one end of described rotating shaft mechanism is provided with padlock portion, this padlock portion offers at least one through hole for padlock; Described clamp be provided with the slot that inserts for described padlock portion and be positioned at the sticking department of described slot away from described rotating shaft mechanism side, described sticking department offers lock hole.
Described rotating shaft mechanism comprises two support portions that described fixed support both sides bend straight up, the top of each described support portion offers axis hole, the both sides of described clamp are provided with two projections with described two corresponding cooperations of axis hole, and described projection to be inserted in described axis hole thus two described support portions are formed described clamp and supports.
Described support bracket fastened base portion is horizontally disposed with, and described padlock portion upwards bends setting, between described support bracket fastened base portion and described padlock portion, be provided with connecting portion.
The bottom in described padlock portion is provided with shoulder structure, and described shoulder structure is used for being inserted into after in described slot on top, described padlock portion withstanding described clamp.
Described base portion offers screw through-hole.
Adopt technique scheme, the handle lock of circuit breaker of the present utility model, compared with prior art, has following beneficial effect:
1. the utility model only comprises fixed support and clamp two parts, simple and stable structure, and parts are few; Fixed support is not offered larger hole slot structure, therefore its structural strength is higher; Clamp has only been offered a slot and a lock hole, manufacturing procedure is simple, and slot is positioned at inside lock hole, and make overall structure comparatively compact, small volume, mounting structure can not take too many space; The lock hole of clamp locks handle station, and the sticking department edge of clamp front portion can also realize locking the stop of another station of handle simultaneously, thus clamp can be shorter, and use material less, the overall structure realizing handle lock is compacter.
2. in the utility model, the base portion of supporting bracket is horizontally disposed with, and described base portion offers screw through-hole, is arranged on existing circuit breaker by screw, and after unlocking, part can retain on-board the circuit breaker, conveniently reuses.
3. padlock portion can offer two lock-receiving aperture, carries out choice for use as required, comparatively flexibly.

Embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
The present embodiment provides a kind of handle lock of circuit breaker, and as shown in Figure 2,3, 4, this handle lock is arranged on circuit breaker 10, can, by the handle locking of circuit breaker at closing position or open position, make it not be misused.
As shown in Figure 1, the handle lock of described circuit breaker is comprised fixed support 1 and is arranged on the clamp 2 on fixed support 1 by rotating shaft mechanism, and described clamp 2 can be rotated relative to fixed support 1 by rotating shaft mechanism.
Described rotating shaft mechanism comprises two support portions 101 that described fixed support 1 both sides bend straight up, the top of each described support portion 101 offers axis hole 102, the both sides of described clamp 2 are provided with two projections 202 with described two corresponding cooperations of axis hole 102, and described projection 202 to be inserted in described axis hole 102 thus two described support portions 101 are formed described clamp 2 and supports.
Two described projections 202 respectively correspondence are stuck in two described axis holes 102, and the line of two described projections 202 is the axis that clamp 2 rotates, and when pulling clamp 2, clamp 2 can rotate, see Fig. 6 around the axis be linked to be of two described projections 202.
