The purpose of this utility model is achieved through the following technical solutions：
A kind of locking mechanism of total air switch, including mounting bracket, the position-limit mechanism located at the mounting bracket；It is described spacing
Mechanism includes key lock, the dead bolt located at the key lock, and the dead bolt can be rotated and stretched with the rotation of the key lock pin
Go out the mounting bracket, the mounting bracket side is provided with the bar hole for coordinating the dead bolt.
The utility model is installed on the side of total air switch by mounting bracket, when total air switch is in open mode
When, the dead bolt of key lock is contracted in bar hole, the automatic disconnection defencive function without influenceing total air switch.And when total empty
When air cock is closed, by rotating key lock, so that dead bolt, which rotates, stretches out bar hole to the top of total air switch, limit total empty
The opening operation of air cock.
Preferred as the utility model, the dead bolt stretches out the bar hole when key lock locking states, in institute
Bar hole described in retraction when stating key lock open mode.The design make it that limitation total air is exactly in during key lock locking to be opened
The state opened is closed, and allows total air switch to open during key lock opening, it is easy to operation.
It is preferred as the utility model, the limit that limitation key is extracted under key lock open mode is provided with the key lock
Position part.When the design make it that key lock is opened, namely total air switch can automatic shutter when, key is can not be out of key lock
Extract, this just effectively prevent the loss of key.
Preferred as the utility model, the end sleeve of the dead bolt is provided with rubber protecting jacket.Because dead bolt is to use metal
Manufacture, it is fixed to put the rubber protecting jacket in order to avoid being accidentally injured when staff operates total air switch by dead bolt.
Preferred as the utility model, the mounting bracket includes orthogonal operation panel and insertion plate, the operation panel
Interior to be provided with the key lock, the insertion plate is provided with the bar hole.The structure of the mounting bracket is simple, and operation panel can be set
In on metope or cabinet face, and insert plate and be inserted into the avris of total air switch and be fixed, the mounting stability of the structure is high.
It is preferred as the utility model, reinforcing plate is provided between the operation panel and insertion plate, the position-limit mechanism is located at
Between the operation panel, insertion plate and reinforcing plate.On the one hand set reinforcing plate strengthens the structural strength of whole mounting bracket, another
Aspect serves the effect of protection position-limit mechanism.
Preferred as the utility model, the operation panel is provided with multiple wall connecting holes, and the insertion plate is provided with more
Individual switch connecting hole.Operation panel and the position such as wall or cabinet face are fixed by wall connecting hole, connected by switching
The side for inserting plate and total air switch is fixed in hole, and fixing intensity is effectively ensured.
Preferred as the utility model, described its one end away from the operation panel of insertion plate is provided with spacing backing plate.It is set
Spacing backing plate is padded on the bottom of total air switch when mounted, to be further ensured that the degree of firmly installing of mounting bracket.
The utility model has the advantages that：Simple in construction, production cost is low, can effectively prevent from opening the mistake of total air switch
Operation, ensure the safety of interlock circuit and equipment.
Brief description of the drawings
Fig. 1 is a kind of front view of embodiment of the present utility model；
Fig. 2 is Fig. 1 right view；
Fig. 3 is the utility model use principle schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
