Description
Technical field
The present invention relates to a kind of open frame circuit breakers, more particularly, to a kind of drawer chassis of frame-type circuit breaker.
Background technique
Open frame circuit breaker is a kind of common low-voltage electrical apparatus, and existing drawer type frame breaker includes drawer chassis and breaks
Road device ontology, breaker body move on drawer chassis, can switch between 3 kinds of different operating positions, be connection position respectively
It sets, experimental site and disengaged position, wherein the movement of breaker body is to be driven to realize by main thread bar screw thread rotation, i.e.,
Artificial to shake rocking handle to drive main thread bar to rotate, the drawer chassis of main thread bar driving breaker body shakes into shaking out, is using
In, the limit reliability of breaker body when moving influences the overall performance of product very big.
Existing open frame circuit breaker generallys use the position limiting structure of both ends setting locator, because domestic assembly technology
Not perfect and drawer chassis part dimensional tolerance is relatively large, and the superposition of tolerance will cause the presence of certain interval.Gap master
It appears between bracket and location nut, external embodiment is to rotate clockwise drawer chassis threaded rod when shaking distant handle
Into after link position, after pressing three position device for locking and unlocking, the distance that half-turn is not waited to 2 circles still can be shaken clockwise.
The presence in gap makes user that can be mistaken for switching not entering into causing extra malfunction in place, i.e., when user shakes switch
When to link position, normal condition no longer needs to shake, but certain customers can be unlocked after the lock of three positions and then be continued due to rawness
It shakes clockwise.At this point, the extruding that can collide between part, the driving force that when over-travel generates is held by threaded rod completely
By.The size that strength is used according to user, will cause thread damage, weld fracture, the different damage such as part breaking as a result,
The damage for ultimately causing circuit breaker device has seriously affected the functional reliability and service life of open frame circuit breaker.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of frame-type circuit breakers
Drawer chassis.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of drawer chassis of frame-type circuit breaker, including L-type sliding panel, threaded rod, limiting device and bracket, the spiral shell
Rasp bar sequentially passes through the preceding bending end and bracket of L-type sliding panel, and the limiting device is installed on the preceding bending end of L-type sliding panel
Between bracket.
Further, the limiting device is the intermediate limit film for being equipped with through-hole, and the threaded rod passes through through-hole.
Further, the limiting device is fixedly connected with the preceding bending end of L-type sliding panel.
Further, the limit film is cylinder, and internal through-hole is equipped with the screw thread matched with threaded rod.
Further, the limit film pass through L-type sliding panel preceding bending end, both ends stretch out, and with preceding bending end
It is fixedly connected.
Further, the limit film is rubber limit film or cork limit film.
Further, the limiting device is spring ring.
Further, the drawer chassis of frame-type circuit breaker further includes location nut, and the threaded rod tail end connects positioning
Nut.
Compared with prior art, the invention has the following advantages that
1, one can be played in user's excessive operation using flexible material by limiting device being equipped in the present invention
Surely the effect buffered, the active force that threaded rod is directly born are transferred on limiting device, are avoided because blending operation leads to ground
Drawer chassis parts depreciation is even failed, and the safety and stability of breaker entirety is improved.
2, the present invention can will be difficult to modified tolerance stack mistake by the size of prefabricated limiting device between original ironware
Difference is adapted to minimum as far as possible, and the scope limitation that user is continued swinging handle is greatly limited and pressed within 1/8 to 1/4 circle
After three position device for locking and unlocking, drawer chassis can continue the distance of movement.
3, the configuration of the present invention is simple is easy to be transformed, can be breaking applied to most frame-types on the market with merging
Device has good commercial value.
4, when user's excessive operation, slight deformation can occur for the limiting device in drawer chassis, and the screw thread for keeping it internal is more
It is closely engaged threaded rod, increases the resistance that user shakes threaded rod, user can be timely feedbacked while buffering and stop behaviour
Make, so that the operating experience of user is be more good.
