Abstract
The utility model provides a kind of circuit breaker chassis, including the drive mechanism that vehicle frame, end carriage and driving vehicle frame are moved horizontally relative to end carriage, and the guider that vehicle frame can be made to keep rectilinear movement is provided between the vehicle frame and end carriage.It can prevent handle from driving in screw mandrel rotation process to be swung in the horizontal direction at left and right sides of vehicle frame.
Description
Technical field
A kind of circuit breaker chassis is the utility model is related to.
Background technology
The push-in and exit function of breaker are realized for convenience, and a chassis of circuit breaker is set below breaker
Car.Existing circuit breaker chassis includes vehicle frame, screw mandrel and handle, is rotated screw mandrel by swinging handle disconnected so as to realize
The propulsion of road device chassis vehicle, exit, operation is light, flexible.But because screw mandrel, handle and vehicle frame in production process and were installed
Because Cost Problems some precision problems can occur with can not avoiding in journey, screw mandrel is existed when being connected with vehicle frame and leave gap etc.
Flaw, structure is not firm enough, and during vehicle frame is promoted and exited, the left and right sides of vehicle frame is easily swung in the horizontal direction
And disequilibrium is so as to causing itself disabler.
The content of the invention
The defects of existing for above-mentioned technology, problem to be solved in the utility model, which is to provide one kind, prevents handle from driving
The circuit breaker chassis swung in the horizontal direction at left and right sides of vehicle frame in screw mandrel rotation process.
In order to solve the above problems, the utility model provides a kind of circuit breaker chassis, including vehicle frame, end carriage and
The drive mechanism that driving vehicle frame is moved horizontally relative to end carriage, being provided between vehicle frame and end carriage can make vehicle frame keep straight line to move
Dynamic guider.
Using the circuit breaker chassis of said structure, vehicle frame is oriented to when driven-mechanism drives and moved horizontally
Device can play the function of making vehicle frame keep rectilinear movement, and vehicle frame will not be made to enter due to coordinate between part not firm enough
The side oscillation of row left and right, while the performance for the breaker for making to be arranged on circuit breaker chassis is more stablized.
As a kind of improvement of the present utility model, drive mechanism includes handle, screw mandrel and the screw pair coordinated with screw mandrel,
Guider includes guide rod and guide holder, and guide rod is be arranged in parallel with screw mandrel, and one end is fixedly connected with end carriage, and the other end is set
Extend into vehicle frame, guide holder is arranged on the guide bar and is fixedly connected with vehicle frame.
Using the guider of said structure, guide rod and be arrangeding in parallel for screw mandrel limit the side that vehicle frame moves horizontally
To, and guide rod extends into vehicle frame, vehicle frame is moved horizontally when pushing ahead by guide rod as track.
Guide holder, which makes guide rod be fixedly installed on vehicle frame, prevents guide rod from swinging, and guide rod is played the work of channeling direction exactly
With.
As further improvement of the utility model, guide holder includes guide table and guide ring, guide table outside and vehicle frame
Inner side is fixedly connected, and guide ring is in cylinder and with being fixedly connected on the inside of guide table.
Using the guide holder of said structure, guide table primarily serves the effect fixed with vehicle frame, and guide ring strengthens guiding
Effect, vehicle frame are pulled on guide rod by guide ring in movement and moved forward and backward.
As another improvement of the present utility model, guider is symmetricly set on the two of screw mandrel using screw mandrel as symmetry axis
Side.
Using the guider of said structure, being symmetrical arranged of guider make its guide effect more stable with it is balanced.
It is described in further detail below in conjunction with the accompanying drawings with embodiment of the present utility model.
Brief description of the drawings
Fig. 1 is the perspective view of the utility model embodiment；
Fig. 2 is the top view of the utility model embodiment；
Fig. 3 is the structural representation of guider in the utility model embodiment.
Embodiment
Circuit breaker chassis as shown in Figure 1 to Figure 3, including vehicle frame 1, end carriage 3 and driving vehicle frame 1 are relative to end carriage 3
The drive mechanism moved horizontally, drive mechanism include handle 22, screw mandrel 2 and the screw pair 21 coordinated with screw mandrel 2, due to
The mode that screw mandrel 2 is connected with screw pair 21 is known in the art technology, and therefore not to repeat here.Between vehicle frame 1 and end carriage 3 also
Guider 4 and the guider 4 of rectilinear movement is kept to be symmetricly set on screw mandrel with screw mandrel 2 for symmetry axis provided with vehicle frame can be made
Both sides.Being symmetrical arranged for guider 4 makes its guide effect more stable and balanced.Vehicle frame 1 driven-mechanism drive and
When being moved horizontally, guider 4 can play the function of making vehicle frame 1 keep rectilinear movement, will not make vehicle frame 1 due to part
Between coordinate not firm enough and carry out left and right side oscillation, while make the performance of breaker being arranged on circuit breaker chassis more
Add stabilization.
Guider 4 includes guide rod 41 and guide holder, and guide rod 41 be arranged in parallel in vehicle frame 1 with screw mandrel 2, guide rod
41 one end is fixedly connected with end carriage 3 in the outside of end carriage 3, and the mode being fixedly connected has many kinds, use in the present embodiment
The mode that is fixedly connected fixed for bolt and nut, the threaded one end that spigot nut 44 and guide rod 41 are arranged on outside end carriage 3 coordinates
Fixed, the other end of guide rod 41 is arranged in vehicle frame 1 and extended into vehicle frame 1, guide holder be set on guide rod 41 and with
Vehicle frame 1 is fixedly connected, and is slidably connected between guide holder and guide rod 41.Guide rod 41 limits car be arrangeding in parallel for screw mandrel 2
The direction that frame 1 moves horizontally, and guide rod 41 extends into vehicle frame 1, enables vehicle frame 1 when pushing ahead by guide rod 41
Moved horizontally as track.The setting of guide holder, which makes guide rod 41 be fixedly installed on vehicle frame 1, prevents guide rod 41 from swinging
So as to not have the effect of channeling direction.Guide holder also includes guide table 43 and guide ring 42, outside and the vehicle frame 1 of guide table 43
Inner side is fixedly connected, and guide ring 42 is fixedly connected in cylinder and with the inner side of guide table 43.Guide table 43 primarily serves and vehicle frame 1
Fixed effect, guide ring 42 strengthen guide effect, and vehicle frame 1 is pulled on guide rod 41 by guide ring 42 in movement and carried out
It is movable.
When in use, breaker is fixedly connected on circuit breaker chassis for the utility model circuit breaker chassis, is shaken
Handle 22, vehicle frame 1 start to move forward, and because the one end of guide rod 41 and end carriage 3 fix guide table 43 and the inner side of vehicle frame 1 admittedly
Fixed, in the moving process of vehicle frame 1, the setting of guide rod 41 serves the effect of channeling direction, and guide ring 42 is on guide rod 41
The direction that sliding moves vehicle frame 1 becomes stable.
Simple text explanation is carried out to the utility model above in association with figure, it is impossible to limit power of the present utility model with this
Sharp scope, in the technical field those of ordinary skill possessed knowledge, the utility model can also not departed from
Various changes can be made on the premise of key element.
