Description
Technical field
The utility model is related to a kind of lock for circuit breaker.
Background technology
Lock for circuit breaker is a kind of electric prospection apparatus more particularly to a kind of lockset for being used to prevent that breaker is misused.
The shortcomings that traditional lock for circuit breaker is：Also have after being positioned to the handle of breaker, between handle and lockset it is certain between
Gap, some movable contacts and the nearer breaker of stationary contact, these gaps are enough the contact for causing contact, so as to cause contingency
Generation.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of safer lock for circuit breaker.
To solve the above problems, the technical solution adopted in the utility model is mainly by lock housing, button, tapered end, " u "-shaped card
Spring, resetting spring combination, the button, which can slide up and down, is installed on lock housing rear end, and the tapered end is fixed on lock housing front end, institute
State that resetting spring is installed in lock housing and both ends are respectively held against button, tapered end, the " u "-shaped clamp spring is installed on button and tapered end
Mounting groove in, the " u "-shaped clamp spring front end gradually inwardly collapse and top outward bending have lock bolt, the tapered end is equipped with
Positioning cams, the positioning cams are used to position the handle of breaker.
The lock for circuit breaker, it is characterised in that：The positioning cams are arranged on the both sides of tapered end, and one side props up disconnected
Handle, the opposite side of road device prop up the housing of breaker.
The lock for circuit breaker, it is characterised in that：The tapered end is integrally formed with positioning cams.
The lock for circuit breaker, it is characterised in that：The lock housing both sides are equipped with mounting groove, the bullet that the button passes through front end
Spring buckle is slidably matched with mounting groove, and the tapered end is coordinated by the hook of rear end with lock housing mounting.
The lock for circuit breaker advantage of the utility model is as follows：Its tapered end is equipped with positioning cams, which is used for
The handle of breaker is propped up, it is positioned, so as to effectively breaker be prevented to be misused.
Description of the drawings
The utility model is described further with reference to Figure of description.

Specific embodiment
With reference to shown in Fig. 1-5, the lock for circuit breaker of the utility model, mainly by lock housing 1, button 2, tapered end 3, " u "-shaped clamp spring
4th, resetting spring 5 combines, and the button 2, which can slide up and down, is installed on 1 rear end of lock housing, before the tapered end 3 is fixed on lock housing 1
End, the resetting spring 5 is installed in lock housing 1 and both ends are respectively held against button 2, tapered end 3, and the " u "-shaped clamp spring 4 is installed on
In the mounting groove 6 and 7 of button 2 and tapered end 3,4 front end of " u "-shaped clamp spring is gradually inwardly collapsed and top outward bending has lock
Door bolt 8, the tapered end 3 are equipped with positioning cams 9, which is used to position the handle 10 of breaker.It uses
When, with hand by button 2 to being pushed forward, 4 front end of " u "-shaped clamp spring is made to stretch out tapered end 3, while 4 front end of " u "-shaped clamp spring can inwardly collapse,
Then lock bolt 8 is aligned to the lockhole 15 of two side guard plate of breaker upper end, finally unclamp hand, " u "-shaped clamp spring 4 is by resetting spring 5
Influence automatically resets so that lock bolt 8 is fastened with a bolt or latch in lockhole 15, so as to complete to lock.Positioning cams 9 can prop up breaker after locking
Handle 10.
Further, the positioning cams 9 are arranged on the both sides of tapered end 3, and the one sides of the positioning cams 9 props up disconnected
Handle 10, the opposite side of road device prop up the housing 12 of breaker.So that the connection between tapered end 3 and breaker is more stablized.
Further, the tapered end 3 is integrally formed with positioning cams 9.In order to produce and improve the firmness of product.
Further, 1 both sides of lock housing are equipped with mounting groove 13, the clamp button of the spring 14 and peace that the button 2 passes through front end
Tankage 13 is slidably matched, and the tapered end 3 is coordinated by the hook 16 of rear end with the lock housing 1 mounting.The connection mode has group
The advantages of dressing is easily and production is simple.
It is upper described, limitation in any form is not done to the utility model, although the utility model is preferably to implement
Case discloses as above, however is not limited to the utility model, and any person skilled in the art is not departing from this hair
In the range of bright technical solution, when structure and technology contents using the disclosure above make a little change or are modified to equivalent change
The equivalence enforcement case of change, but every content without departing from technical solution of the present invention, technical spirit according to the invention to
Any simple modification, equivalent change and modification that upper case study on implementation is made, still belongs to technical solutions of the utility model scope.
