Abstract
The invention discloses an interlocking mechanism of a low-pressure drawer type switch cabinet. The interlocking mechanism comprises a torsion arm, a fan-shaped wobble wheel and a gear rack, wherein the fan-shaped wobble wheel is driven by the torsion arm; the gear rack is fixedly arranged on a leading-in plug; a square driving block is arranged on a rotating shaft of the torsion arm; the center of the fan-shaped wobble wheel is mounted on the square driving block; a gear is arranged on a wheel rim of the fan-shaped wobble wheel; the gear is meshed with the gear rack; and a limiting block is arranged at a position corresponding to a stoppage position of the torsion arm. The interlocking mechanism of the low-pressure drawer type switch cabinet, which is provided by the invention, the driving is carried out by adopting a gear rack transmission way; the leading-in plug can stably enter a leading-in plug operating hole; the running stability of the whole interlocking mechanism is guaranteed; moreover, due to the existence of the limiting block, the possibility of misoperation can be further prevented; the fan-shaped wobble wheel is guaranteed not to be disengaged from the gear rack; moreover, the torsion arm is guaranteed to be in elastic contact with the limiting block by means of a supporting spring; and the running safety of the whole mechanism is guaranteed.
Description
Technical field
The present invention relates to a kind of interlocking device of low pressure drawer-type switch cabinet.
Background technology
Patent of invention number is 200710047592 incorrect operation preventing interlocking apparatus disclosing a kind of low pressure drawer-type switch cabinet.This patent is driven by the main handle 01 of interlocked control and hangs pin 2 and do circle swing, and the swing of hanging pin 2 promotes lock pin 3 and does rectilinear motion, and then realizes incoming line plug and enter in plug handle hole 5.
The problem of these innovation and creation is, rectilinear motion is done by the wobble drive lock pin 3 hanging pin 2, its motion itself is steady not, and because the stress point moment of lock pin 3 all changes, so also make incoming line plug in the process of advancing, due to the existence of torsion, easily occur small drift angle, this just makes incoming line plug stable not with contacting of incoming line plug handle hole 5.
Summary of the invention
The object of this invention is to provide the interlocking device that rigid contact stablized by a kind of incoming line plug and incoming line plug handle hole.
The object of the invention is to be achieved through the following technical solutions:
A kind of interlocking device of low pressure drawer-type switch cabinet, comprise torque arm, the fan-shaped escapement driven by torque arm, the tooth bar be fixed on incoming line plug, the rotating shaft of described torque arm is provided with square drive block, the center of described fan-shaped escapement is arranged on square drive block, the wheel rim place of fan-shaped escapement is provided with the gear teeth, the described gear teeth are meshed with tooth bar, and the rest position of corresponding described torque arm is provided with guide vane end stop.
Described guide vane end stop is arranged on one and has in the groove of support spring, carries out Elastic Contact to make described torque arm in rest position and guide vane end stop.
The interlocking device of low pressure drawer-type switch cabinet provided by the invention, the mode of rack-driving is adopted to drive, incoming line plug can be entered in incoming line plug handle hole stably, ensure that the stationarity that whole interlocking device operates, and due to the existence of guide vane end stop, the possibility of misoperation can be prevented further, ensure that fan-shaped escapement is not separated with tooth bar, and ensure that torque arm and guide vane end stop carry out Elastic Contact by support spring, ensure the fail safe of whole mechanical operation.
Accompanying drawing explanation
Fig. 1 is the structure chart of the interlocking device of low pressure drawer-type switch cabinet described in the embodiment of the present invention.
Embodiment
According to drawings and embodiments the present invention is described in further detail below.
As shown in Figure 1, the interlocking device of the low pressure drawer-type switch cabinet described in the embodiment of the present invention, comprise torque arm 1, the fan-shaped escapement 2 driven by torque arm 1, the tooth bar 4 be fixed on incoming line plug 3, the rotating shaft of described torque arm 1 is provided with square drive block 5, the center of described fan-shaped escapement 2 is arranged on square drive block 5, the wheel rim place of fan-shaped escapement 2 is provided with the gear teeth, and the described gear teeth are meshed with tooth bar 4, and the rest position of corresponding described torque arm 1 is provided with guide vane end stop 6.
Described guide vane end stop 6 is arranged on one and has in the groove 8 of support spring 7, carries out Elastic Contact to make described torque arm 1 in rest position and guide vane end stop 6.
The interlocking device of low pressure drawer-type switch cabinet provided by the invention, the mode of rack-driving is adopted to drive, incoming line plug can be entered in incoming line plug handle hole 9 stably, ensure that the stationarity that whole interlocking device operates, and due to the existence of guide vane end stop, the possibility of misoperation can be prevented further, ensure that fan-shaped escapement is not separated with tooth bar, and ensure that torque arm and guide vane end stop carry out Elastic Contact by support spring, ensure the fail safe of whole mechanical operation.
