Abstract
The invention discloses a sleeve with a locking device. The sleeve with the locking device comprises a sleeve part and a supporting base plate; a fixing through hole is formed in the middle of the supporting base plate; a pair of connection lug shafts are arranged on the lateral wall of the sleeve part; a first limiting long groove is formed between the connection lug shafts; and a second limiting long groove is formed in the lateral wall of the sleeve part. The sleeve with the locking device provided by the invention uses the first limiting long groove and the second limiting long groove which are mutually vertical. After an air plug of a pneumatic door is opened, a driving shaft of the pneumatic door is limited by the two limiting long grooves of the sleeve, so that the door leaf is prevented from being moved; and the security property of the pneumatic door is improved.
Description
Technical field
The present invention relates to a kind of pneumatic door, more precisely a kind of sleeve of locking device of pneumatic door.
Background technology
Pneumatic door is a kind of industrial closing device commonly used, and use occasion is very extensive, can utilize pneumatic means to control door leaf.Without any stopping means, after vent plug was open, random activity easily occured in whole door leaf, causes the generation of potential danger on the driving shaft of existing pneumatic door.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby a kind of sleeve of locking device is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of sleeve of locking device, the sleeve of described locking device comprises a sleeve part and a support chassis, the middle part of described support chassis is provided with a fixed via, the sidewall of described sleeve part is provided with a pair of connection gudgeon, form one first spacing elongated slot between the described connection gudgeon, the sidewall of described sleeve part is provided with one second spacing elongated slot.
As preferred embodiment of the present invention, the setting party of described the second spacing elongated slot is to mutually vertical with the described first spacing elongated slot.
As preferred embodiment of the present invention, the width of described the second spacing elongated slot is greater than the width of described the first spacing elongated slot.
The sleeve of locking device of the present invention utilizes the orthogonal first spacing elongated slot and the second spacing elongated slot, after the vent plug of pneumatic door is open, the driving shaft of pneumatic door can be limited by two spacing elongated slots, thereby prevents the activity of door leaf, has improved the security performance of pneumatic door.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
