Description

Electric control box and electrical control cabinet side operation interlocking mechanism

Technical field

The utility model belongs to electric operation safety device field, field, relates to a kind of electric control box and electrical control cabinet side operation interlocking mechanism, is applicable to the interlocking of operation outside electric control box, the electrical control cabinet side.

Background technology

Development along with high and low pressure distribution industry, the raising that it requires aspect technical performances such as practicality, safety, interlocking security performance to electric control box, electrical control cabinet operation requires also more and more higher, itself is not with interlocking device present electric elements, order price is higher separately, and be that the chain situation in Qianmen is many, inconvenient operation.Interlocking gear is operated at home seldom in the side, but security performance requirement now is more and more higher, also requires the side interlocking.

Summary of the invention

Problem to be solved in the utility model is, overcome the deficiencies in the prior art, a kind of electric control box and electrical control cabinet side operation interlocking mechanism are provided, by mechanism's component parts locking and hanging hook, the stopper hook shows support, sideboard, the requirement of interlocking is satisfied in the cooperation of extension spring etc., solves the interlocking of operated products outside electric control box, the electrical control cabinet side, better meets the safety requirements of electric utility.

The utility model solves its technical problem and takes following technical scheme to realize:

A kind of electric control box and the electrical control cabinet side operation interlocking mechanism that provide according to the utility model, comprise the stopper hook, locking and hanging hook, show support and sideboard, have two

circular holes

21,22 on the described stopper hook 1, and by positioning stud 9,9 ' be connected on the chamber door 10, have a square hole 13 on the locking and hanging hook 2, handle extension rod 11 penetrates wherein, have two screwed holes 14,15 at the locking and hanging hook edge, one of them screwed hole 14 is fixed on locking and hanging hook on the handle extension rod, and another screwed hole 15 is installed and shown support 3; Show on the support and have a circular hole 20, to show that support is fixed on the locking and hanging hook and with locking and hanging hook rotates, have two circular holes 16 on the

sideboard

4,17, one of them circular hole 17 is fixed on the positioning stud 8 rotating shaft as sideboard, another circular hole 16 is connected with extension spring 5, extension spring is fixed on the sideboard, the other end of extension spring is fixed on the positioning stud 6 of wall box 12, on sideboard, have a slotted hole 18, it cooperates with positioning stud 7, be used for to sideboard spacingly, on sideboard, have a groove 19, be used for the lock handle extension rod.

The utility model compared with prior art has significant advantage and beneficial effect:

Because the utility model adopts handle extension rod location locking and hanging hook, sideboard, show that the stopper hook of installing on support and electric control box, the electrical control cabinet door matches, when door is closed, the stopper hook will be discharged for the certain thrust of sideboard by the extension rod that sideboard locks, thereby can the rotary handle closure, this moment, locking and hanging hook was hooked on the stopper hook, had guaranteed the handle rotation to be disconnected when opening the door once more to open chamber door.Transparency window is installed on door, is shown that the label on the support shows with the same state of handle this moment, make the operator can see through well-illuminated window and observe on off state.When opening in advance, rotary handle breaks away from locking and hanging hook and stopper hook, and this moment, the stopper hook was given the thrust cancellation of sideboard, and sideboard is locked the handle extension rod by the pulling force of extension spring once more.Thereby guaranteed to switch at the non-rotatable main circuit of door opening lower handle.This interlocking device can satisfy the safety requirements of electric switch operation.Simple to operation, the tangible safety instruction of operator is given in interlocking device's hommization.Also save production cost simultaneously, reached the purpose of production safety.

In a word, when using the utility model, main circuit must disconnect electric control box, the electrical control cabinet door just can be opened, and electric control box, electrical control cabinet door must be closed main circuit and just can be switched on.

Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Embodiment

Below in conjunction with accompanying drawing and preferred embodiment, embodiment, structure, feature and effect thereof that foundation the utility model is provided, describe in detail as after.

A kind of electric control box shown in Fig. 1～7c and electrical control cabinet side operation interlocking mechanism, comprise the stopper hook, locking and hanging hook, show support and sideboard, have two

circular holes

sideboard

Stopper hook 1 is that its forming dimension of t=2.0 cold drawing bending and forming and installation site determine at random that according to body structure it is connected on the chamber door by double-screw bolt.The hook of locking and hanging hook 2 carbon steel materials, middle opening square hole guarantee that the handle extension rod penetrates freely, and open the M5 screwed hole one of them is used for fixing hook usefulness at the edge, and another is used for installing the demonstration support.Locking and hanging hook guarantees to cooperate the unlatching of control gate with the stopper hook.Show that support 3 can determine as the case may be for its forming dimension of t=2.0 cold drawing bending and forming.Show that support is fixed on hook and goes up with the hook rotation, the state of demonstration is alternately changed.The operator can determine the state of main circuit accurately.Sideboard 4 can be determined as the case may be for its forming dimension of t=2.0 cold drawing bending and forming.Sideboard has two circular holes, and one of them is fixed on the double-screw bolt as the rotating shaft of sideboard, and another circular hole is connected with extension spring, and extension spring provides pulling force, makes its lock handle extension rod accurately after door is opened, and main circuit can not be switched on when guaranteeing that door is opened.It cooperates with double-screw bolt and is used for to sideboard spacingly to open slotted hole on its basal plane, guarantees that it does not interfere with other parts.In position fluting is used for the lock handle extension rod.Extension spring 5 is the standard extension spring, and an end is fixed on the sideboard, and an end is fixed on the double-screw bolt of wall box, and its effect is to provide pulling force for sideboard.Shared 3 positioning studs of this mechanism, one is used for the spacing of sideboard, and one is used to the sideboard location and carries enough rotating shafts, and last is that fixedly extension spring is used.The position of three double-screw bolts is determined as the case may be.

Characteristics of the present utility model are:

Electric control box, give sideboard thrust by the stopper hook that is installed on the chamber door when electrical control cabinet door is closed, be the release of handle extension rod, thereby handle can be rotated, locking and hanging hook is locked on the stopper hook simultaneously, show that support shows current state, the main circuit energising, as shown in Figure 2.

Electric control box, when the electrical control cabinet door is opened, must first rotary handle, disconnect main circuit, make the disengaging of locking and hanging hook and stopper hook. The playback of extension spring pulling this moment sideboard. Make sideboard pin the handle extension rod, guarantee that handle cannot rotate the connection main circuit, as shown in Figure 3.
