Description

A kind of appliance switch cabinet pull handle with self-locking mechanism

Technical field

The utility model relates to the electrical switchgear technical field, concrete relates to a kind of appliance switch cabinet pull handle that has self-locking mechanism that is used in the switch cubicle.

Background technology

Existing switch cubicle is generally drawer-type switch cabinet, at present, the low pressure drawer-type switch cabinet that uses on the market, many products that still adopt old standard production promptly have only connection, extract two grafting and demonstration out, and generally do not establish locking device.New national standard is formulated with reference to the like product international standard, regulation pull-out type low-voltage complete equipment must have three demonstrations, location and operation locking, increase test position, the secondary plug-in unit is communicated with during this position, outlet plug breaks away from, and cell gate is not opened when requiring test position, does not reduce the shell protection grade.In order to adapt to new national standard, each producer improves design on the basis of former two propulsive mechanisms, designs cycle type and propulsive mechanism rotating disc type, cycle type complex structure; Rotating disc type is that so-called machete slice structure is simple, but effort and easily produce misoperation.

The utility model content

Technical problem to be solved in the utility model is, overcomes the problem that exists in the existing switch cubicle mechanism, and a kind of appliance switch cabinet pull handle that is used for the band self-locking mechanism of drawer-type switch cabinet is provided.

In order to address the above problem the technical solution of the utility model is such:

A kind of appliance switch cabinet pull handle with self-locking mechanism, comprise the self-locking mechanism that has handle that is arranged on the switch cabinet drawer, and be arranged on self-locking groove on the switch cubicle dividing plate, it is characterized in that described self-locking mechanism comprises a lock body, lock body is arranged on the switch cabinet drawer, has reciprocating push rod in the lock body, described push rod connects the swing arm that can swing, and described swing arm connects a lock pin that can laterally reciprocatingly slide, and described lock pin is corresponding with self-locking groove position.

Described handle is fixed on the front panel of switch cabinet drawer, and it is one reducible by press button that an end of handle has, and presses the press button actuating type and connects push rod in the self-locking mechanism, is with a back-moving spring on the push rod.

Described press-side by press button has the hook lock of padlockable, after hook lock hangs up lock, can't push self-locking mechanism also stable stopping under a certain state simultaneously to inside by press button; As take down padlock, and then can push to inside by press button, when pushing, push rod drives swing arm, and swing arm drives lock pin makes it break away from lock hook slot, and drawer can inside and outside pulling.

Described lock groove is two, a service position, and another is the dropout position, when the pulling drawer, can make it be parked in the position of certain corresponding lock groove.

Beneficial effect, the utility model delicate structure is pushed flexibly, and is easy to use, padlock is set can effectively places the unrelated person squeeze grip, and operation has guaranteed the safe operation of equipment beyond avoiding.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is the structural representation of a kind of appliance switch cabinet pull handle with self-locking mechanism of the utility model;

Fig. 2 is that the A of Fig. 1 is to structural representation.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
