Description
Technical Field
The utility model relates to a self-lock device especially relates to a construction elevator guard gate self-lock device.
Background
In the building construction, the safety problem has been a long-lasting hot topic, which not only gives more and more attention to the safety problem because of the personnel related to the construction site, but also fully explains a fact: the site safety is too poor, and a small careless mistake can result in serious damage which can not be retrieved. In construction site, the protection of the edge opening prevents the high fall, which is the most important thing. In the past construction safety inspection, the opening and closing of a protective door at a construction elevator platform are often found to be a weak link, and the illegal phenomena that the protective door at the elevator platform is not closed or people in a building open privately often exist. The research shows that the problem has the following reasons: 1. the bolt is closed to protection door in the past can only open the outside and close in the elevator driver outside in the construction elevator, can not the inboard and close, and it is not very convenient to operate. 2. Round steel is used to the bolt, and the bolt mouth is formed with the pipe preparation, and this has led to two problems: firstly, the time is one long, and the bolt mouth is flat head easily and is out of shape, leads to the bolt to insert into. Secondly, the bolt opening and the bolt are easy to be misplaced and misaligned, so that the bolt cannot be inserted into the elevator door, and the elevator protective door cannot be closed.
In view of such a phenomenon, a device which can be closed by a constructor in a building or a person in an elevator and can be opened only by the constructor in the elevator is researched. The defect that the construction elevator can only be opened and closed by personnel in the construction elevator is overcome, and the problem that the bolt opening is not closed due to easy deformation, displacement and the like is also solved.
Disclosure of Invention
In view of this, the utility model aims at providing a construction elevator guard gate self-lock device, aim at solving the drawback that can only the manual work open and close to and the bolt mouth warp easily, for etc. lead to closing defect not last.
In order to achieve the purpose, the technical scheme is as follows:
the self-locking device for the protective door of the construction elevator comprises angle iron and a self-locking device, wherein the angle iron and the self-locking device are fixedly arranged on the protective door;
self-lock device is including rotating piece and mounting, mounting fixed mounting is on one side guard gate, and the mounting is right angle shape, and mounting one end is fixed on opposite side guard gate, the other end with the one end of rotating the piece is rotated and is connected, rotates the piece other end overlap joint on the angle bar.
As a further improvement, the rotating member and the fixing member are made of angle steel.
As a further improvement, when the rotating part is lapped on the angle iron, the end lapped on the angle iron is lower than the end connected on the fixing part in a rotating way.
As a further improvement of the present invention, the rotating member is connected to the fixing member through a rotation shaft.
The utility model has the advantages that: the utility model discloses simple manufacture, design benefit is reasonable, convenient operation and safety are fit for promoting, and the cost is very low, and easy to assemble is convenient moreover to be dismantled.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this application, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. In the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The self-locking device for the protective door of the construction elevator comprises an angle iron 1 and a self-locking device 2, wherein the angle iron 1 and the self-locking device 2 are fixedly arranged on the protective door;
self-lock device 2 is including rotating piece 21 and mounting 22, it adopts the angle steel to make to rotate piece 21 and mounting 22, mounting 22 fixed mounting is on one side guard gate, and mounting 22 is the right angle shape, and mounting 22 one end is fixed on opposite side guard gate, the other end with the one end of rotating piece 21 is rotated and is connected, rotates the overlap joint of 21 other ends on angle bar 1, when rotating piece 21 overlap joint on angle bar 1, the one end of overlap joint on angle bar 1 is less than the one end of rotating the connection on mounting 22, it connects on mounting 22 through axis of rotation 23 to rotate piece 21.
Self-lock device 2 need not operate closing means specially when closing the guard gate, rotates piece 21 and utilizes the dead weight to play a self-locking effect, and operating personnel can fall the lock automatically as long as close the guard gate gently. When the door is opened, the rotating piece 21 is slightly held up by people outside the door, and the door is convenient and safe to operate.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
