Abstract
A novel breaker crank handle mainly solves problems that present crank handle occupies a lot of internal spaces of the breaker and influences miniaturization of the breaker. The crank handle is characterized in that a cantilever (2) is provided with a first sliding groove (21) and a second sliding groove (22); a hexagonal rotating shaft (1) is provided with a first pin (4) adapted with the first sliding groove (21); a handle (3) is provided with a second pin (5) adapted with the second sliding groove (22). The novel breaker crank handle is provided with the sliding grooves, and in premises of ensuring a normal use of the crank handle, an occupation space of the crank handle is greatly minimized, thereby promoting miniaturization of the breaker.
Description
Technical field
The utility model relates to a kind of crank handle, is specifically related to a kind of novel breaker crank handle.
Background technology
Circuit breaker is a kind of existing hand switch effect, can automatically transship again and the electrical equipment of short-circuit protection.It can be used to distribute electric energy; do not start continually asynchronous motor; power circuit and motor etc. are carried out protection, can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for their, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And behind the disjunction fault current, generally do not need to change parts, therefore obtain a wide range of applications.
Propulsive mechanism is the important mechanism of omnipotent breaker, and circuit breaker must be borrowed the machine driving of outer power, handcart promotion position before operation.The mechanically operated mode of many employings mainly is screw driven structure.Use crank handle rotating screw bolt main shaft, thereby drive the handcart translation, and crank handle is installed in circuit breaker inside.Because crank handle length when free state is longer, can take a large amount of free spaces in the circuit breaker, be unfavorable for the miniaturization of circuit breaker.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of novel breaker crank handle, has mainly solved existing crank handle and can take a large amount of circuit breakers inner space, affects the problem of circuit breaker miniaturization.
The technical scheme that the utility model adopts is: a kind of novel breaker crank handle, comprise hexagonal rotating shaft, cantilever, handle, described cantilever is provided with the first slippage slot, the second slippage slot, be provided with the first bearing pin in the described hexagonal rotating shaft, described the first bearing pin and the first slippage slot are suitable, be provided with the second bearing pin in the described handle, described the second bearing pin and the second slippage slot are suitable.
Described cantilever is provided with standing groove, and described cantilever and handle are provided with constriction plate, and described constriction plate and standing groove are suitable.
The beneficial effects of the utility model are: be provided with slippage slot, guaranteeing that crank handle normally uses under the prerequisite, greatly reduced the shared space of crank handle, promoted the circuit breaker miniaturization.
Description of drawings
Fig. 1 is the utility model structural representation.
1-hexagonal rotating shaft among the figure, 2-cantilever, 21-the first slippage slot, 22-the second slippage slot, 3-handle, 4-the first bearing pin, 5-the second bearing pin, 6-standing groove, 7-constriction plate.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of novel breaker crank handle, comprise hexagonal rotating shaft 1, cantilever 2, handle 3, described cantilever 2 is provided with the first slippage slot 21, the second slippage slot 22, be provided with the first bearing pin 4 in the described hexagonal rotating shaft 1, described the first bearing pin 4 and the first slippage slot 21 are suitable, are provided with the second bearing pin 5 in the described handle 3, and described the second bearing pin 5 and the second slippage slot 22 are suitable.
Described cantilever 2 is provided with standing groove 6, and described cantilever 2 is provided with constriction plate 7 with handle 3, and described constriction plate 7 is suitable with standing groove 6.
The concrete use of the utility model is as follows: during use, crank handle is converted into Z-type, holds handle 3 and rotation, handcart is pushed into the service position; After finishing the work, hexagonal rotating shaft 1, cantilever 2, handle 3 are put into yi word pattern and the promotion of first center, bearing pin is moved along slippage slot, contracting mechanism has effectively reduced the volume when crank handle is not worked.
The beneficial effect of utility model is: be provided with slippage slot, guaranteeing that crank handle normally uses under the prerequisite, greatly reduced the shared space of crank handle, promoted the circuit breaker miniaturization.
Claims (2)
