Technical field

The present invention relates to switch enclosure technical field, especially a kind of switch enclosure mechanism for quick fixing and its switch enclosure.

Background technique

Valve limit switch box is also known as letter in reply device or information transmitter, and built-in limit switch is divided into Direct Travel and angle stroke two Class, referred to as are as follows: Direct Travel switch enclosure and angle travel switch box, mainly for detection of valve state, and by the unlatching of valve or Closed position is exported with the signal of switching value, in order to remotely control.

In all kinds of pipe network systems of valve application, automation control application increasingly becomes necessarily needing for pipe network control It asks, the switch control and position of the switch feedback to valve in pipe network have become the basic function of pipe network control, valve automation control System also becomes the basic control unit of pipe network process control.Therefore, the application of valve limit switch box is also more and more extensive, Such as numerous industries of petrochemical industry, water process, space division；

Since switch enclosure is using more and more extensive, the installation convenience of switch enclosure is required also higher and higher, it is desirable that switch Box being capable of Fast Installation and safe and reliable；It is installed in such a way that support bracket bolt connects currently, valve limit switch box is commonly On the actuator of valve, and the position of threaded hole is installed in the bottom of valve, however this kind of mounting structure is on the one hand due to branch The presence of frame, not only increases cost, also increases volume；Another party will lead to since the height of bracket itself is generally the bottom of compared with It is inconvenient when in-site installation, it is not easy to tightening for bolt, it is difficult to improve working efficiency and installation quality；Execution different simultaneously Device also needs to design and produce different brackets, undoubtedly will also result in working efficiency is lower, the time of delivery is longer, cost relatively Height not only increases the cost of both sides of supply and demand, and requirements of installation space is larger, especially for some applied fields for having space to limit It closes, will cause the problem of can not installing and using.

Summary of the invention

The technical problem to be solved by the present invention is in order to solve the connection that switch enclosure in the prior art uses support bracket bolt Mode is installed on the actuator of valve, leads to big installation volume, installation inconvenience, production cycle length and problem at high cost, existing A kind of switch enclosure mechanism for quick fixing and its switch enclosure are provided, to reach Fast Installation by mechanism for quick fixing, reduce and install Space, the purpose for reducing application cost and improving efficiency.

The technical solution adopted by the present invention to solve the technical problems is: a kind of switch enclosure mechanism for quick fixing, described to open Closing box includes box body, which includes:

Fixedly connected part, has internal interconnecting piece and external connection portion, and the bottom surface of the box body is offered for merging pair The jack of interior interconnecting piece；

And locking member, matched for the internal interconnecting piece with fixedly connected part, the side of the box body offer with The locking hole that jack is connected, the locking member configuration is in locking hole, when locking member direction is located at the internal connection in jack When portion is mobile, locking member is contacted with internal interconnecting piece, and gradually compresses internal interconnecting piece.

It is fixedly connected using the external connection portion of fixedly connected part with actuator in this programme, fixedly connected part internally connects Socket part is then inserted into the jack of box body, and box body is pressed on internal interconnecting piece using locking member, thus realize box body with Actuator is directly connected to, and locking member is located at the side of box body, so as to carry out installation operation from the side of box body, intuitively Convenient, installation effectiveness is high.

Further, the internal interconnecting piece be equipped with for and the mating surface that matches of locking member, the mating surface by Up to lower inward slant；Using operation locking member drawn close to the internal interconnecting piece of fixedly connected part when, by locking member with internally connect The inclined cooperation face contact of socket part, makes box body to bottom offset, and the bottom hole of box body internal plug seat is made to be pressed on internal interconnecting piece Top realized with this and box body is rapidly secured in fixedly connected part so that box body and locking member be made to clamp internal interconnecting piece, And it is safe and reliable, structure is simple and efficient.

Further, the mating surface is small top and big bottom circular conical surface.

Further, the mating surface is inclined-plane.

Further, the locking member is threadedly coupled with the locking hole of box body side.

For the ease of the connection of fixedly connected part and actuator, further, the external connection portion of the fixedly connected part It is equipped with external screw thread；So as to which the external connection portion of fixedly connected part is directly threadedly secured in the mounting hole of actuator, side Just it installs.

Further, the two sides of the box body are respectively provided with the locking member, and the locking member and fixedly connected part one are a pair of It answers；It is solid that box body installation can be improved in the fixedly connected part that locking member is respectively set using the two sides in box body and cooperates with locking member Fixed stability.

The present invention also provides a kind of switch enclosures, including above-mentioned switch enclosure mechanism for quick fixing.

Further, the switch enclosure is valve limit switch box, and the external connection portion in the fixedly connected part is fixed In the mounting hole of actuator.

The beneficial effects of the present invention are: switch enclosure mechanism for quick fixing of the present invention its use locking member cooperate fixedly connected part Mode, switch enclosure and actuator are directly connected to realizing, without bracket, cost, raising production efficiency can be reduced；And structure Simply, high reliablity, installation is also convenient rapid, is applicable to the actuator of different size；Pacified simultaneously from the side of box body Fill the design of operation, it can be achieved that box body during installation needed for installation space it is small, be easily installed operation, raising installation effectiveness, and can Carried out under pipeline intensively equal small spaces using.
