Description

A spacing brace for central overhead door

Technical Field

The utility model belongs to the technical field of decoration doors and windows, and particularly relates to a limiting support for a central hanging door.

Background

In life, a flat sliding door is often seen in hotels, shopping centers and exhibition centers, the sliding door needs to be manually pushed when being opened, and the flat sliding door is a common floor spring door, and the floor spring door has the defects of relatively large quantity because the technology is old, for example, a large hole needs to be dug in the ground because a floor spring hydraulic device needs to be installed, for example, as the use frequency is increased along with the time, the hydraulic device can be aged, and the use experience can be reduced. In order to meet the trend of the thin floor of the modern building, the central hanging door is produced, the surface of the floor cannot be damaged when the central hanging door is installed, the hidden rotating shaft is used and hidden in the door body, the central hanging door is suitable for places where the ground bounce door is difficult to install, and the rotating shaft at the top can be suitable for various options. The center overhead door can also interlock with smoke inductor, can reliably open or close under special circumstances, be applicable to as preventing fire door, smog, or emergency exits, it has the decorative sheet rubber to attach in the center overhead door, be used for control speed and spring tensioning, need not open subaerial lid like floor spring and adjust hydraulic means, in the aspect of the installation, the center overhead door has used sliding base, as long as the centering is aimed at, the installation is very easy, the center overhead door is when 5 meters wide, the biggest heavy bearing can reach 1600KG, the problem that the ground bouncy door can only reach 300KG because of structural problem leads to the biggest bearing has been solved.

The existing center-hung product does not have a 90-degree stop position, so a mechanical device needs to be added to the center-hung door to realize the 90-degree stop position of the door leaf. The current domestic limit technology mainly uses a hidden bolt: the device is arranged at the lower end of a vertical frame in the door leaf, and when the door leaf is opened to 90 degrees, the blind bolt deflector rod is manually controlled to enable the blind bolt to be inserted into the ground dust-proof cylinder, so that the stop function is realized. The stop device is easy to damage and has high maintenance rate; and the hidden bolt deflector rod can be controlled only by bending down or squatting down, so the operation is complex. The limit braces imported from abroad have the defect of obviously weak door stopping force. When the wind pressure is slightly large, the door leaf can lose the function of stopping. And the limit supports of the imported brands have higher purchase price.

Accordingly, the present application has been made in view of the above circumstances in the prior art, and has made relevant research and design.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides the limiting support for the central hanging door, which has the functions of accurate limiting and automatic stopping, greatly reduces the cost compared with the imported limiting support and has wide market prospect.

In order to solve the above technical problems, the present invention is solved by the following technical solutions.

A limiting support for a central hanging door comprises a sliding rod seat, a sliding rod and a sliding groove. The sliding rod seat is installed on the upper beam of the door pocket, one end of the sliding rod is rotatably assembled on the sliding rod seat, the other end of the sliding rod is connected with a sliding block, the sliding block is assembled in a sliding groove, and the sliding groove is installed above the door body of the central hanging door. Be equipped with the locating part in the spout, the locating part includes the stopper, the stopper bottom is connected with elastic element. The stop position is realized by the cooperation of the limiting part and the sliding block.

In a preferred embodiment, the slider lower surface is equipped with the slip arch, the stopper upper surface is equipped with spacing arch, 90 off-positions of the door body are realized in locating part and slider cooperation, and simple structure is reliable, and the off-position is accurate, and later maintenance is convenient.

In a preferred embodiment, the elastic element is a spring, and the spring can adjust the compression amount, so that the compression amount of the spring can be conveniently adjusted in advance, and the door stopping force and the door closing force are controlled at a proper force position.

In a preferred embodiment, the limiting block is made of a nylon block, so that the device is prevented from being damaged by hard collision.

Compared with the prior art, the method has the following beneficial effects: the automatic stop device has the functions of accurate limiting and automatic stop, greatly reduces the cost compared with an imported limiting support, and has wide market prospect.

Refer to fig. 1 to 3.

A limiting support for a central hanging door comprises a sliding rod seat 1, a sliding rod 2 and a sliding groove 4. The sliding rod seat 1 is assembled on the upper beam of the door pocket 8 through screws, one end of the sliding rod 2 is rotatably assembled on the sliding rod seat 1, the other end of the sliding rod 2 is connected with a sliding block 3, the sliding block 3 is assembled in a sliding groove 4, and the sliding groove 4 is assembled above a door body 7 of the central hanging door through screws. Be equipped with the locating part in the spout 4, the locating part includes stopper 5, stopper 5 bottom is connected with elastic element. The stop position is realized by the cooperation of the limiting part and the sliding block 3.

Specifically, 3 lower surfaces of slider are equipped with the

slip arch

31, 5 upper surfaces of stopper are equipped with spacing arch 51, 90 off-positions of the door body 7 are realized in the cooperation of locating part and slider 3, and simple structure is reliable, and the off-position is accurate, and the later maintenance is convenient. The elastic element is a spring 6, the spring 6 can adjust the compression amount, the compression amount of the spring 6 is convenient to adjust in advance, and the door stopping force and the door closing force are controlled at a proper force position.

Furthermore, 5 materials of stopper are the nylon piece, avoid hard collision damage device.

When the door body 7 of the central hanging door is in a closed state, the sliding block 3 is positioned on one side, far away from the door shaft, in the sliding groove 4. Along with the opening rotation of the door body 7, the sliding block 3 slides towards the direction of the door shaft under the pulling of the sliding rod 2. When the protruding 31 of slip of slider 3 and the spacing protruding 51 contact of stopper 5, will push away the dynamics of door and strengthen, spacing spring 6 is compressed, and slider 3 passes through the locating part, and spring 6 replies, and stopper 5 moves up and restricts slider 3 and remove, and the door body 7 and door pocket 8 are 90 this moment. Because the spring 6 is higher in strength, the door stopping force of the door body 7 is larger, and the door stopping position is more stable than the limiting support of the inlet.

This application leads to spring 6 and nylon stopper 5 as the main core component of off-position mechanism, has realized accurate spacing and automatic off-position function, and the cost is greatly reduced than the spacing support of import, has wide market prospect.

The scope of the present invention includes, but is not limited to, the above embodiments, and the present invention is defined by the appended claims, and any alterations, modifications, and improvements that may occur to those skilled in the art are all within the scope of the present invention.
