Heavy mounting position-adjustable 90-degree door opener

Abstract

The invention discloses a heavy mounting position-adjustable 90-degree door opener, and belongs to the technical field of door openers. The heavy mounting position-adjustable 90-degree door opener comprises a door opener body, an adjusting mechanism is arranged on the outer side of the door opener body, a positioning mechanism is arranged in the adjusting mechanism, the positioning mechanism is located on the front side of the door opener body, a connecting rod is arranged in the door opener body, a hollow shaft is fixedly connected with the lower surface of one end of the connecting rod, and a shaft sleeve sleeves the outer side of the hollow shaft. A mounting plate, an L-shaped movable hanging piece and a positioning plate are all made of metal materials, a door frame and a wall are connected through metal parts, the standard load bearing is 400 KG or above, the whole set of door opener can be directly mounted on the door frame, mounting is easy and convenient, the time for field adjustment is eliminated, the blank that a 90-degree door opener body cannot be used for a heavy door is filled, the mounting steps of the 90-degree door opener body are simplified, the safety is improved, the door body can be mounted in the middle, and the protection safety of the door body is improved in the field of medical lead doors.

Description

technical field [0001] The invention belongs to the technical field of door openers, in particular to a heavy-duty 90° door opener with adjustable installation positions. Background technique [0002] The door opener is a drive composed of a motor, a controller system, a speed change mechanism, and a clutch device, and is an electromechanical product. It is usually used to realize the electric opening and closing of various doors. At present, the 90° door openers on the market have a load of 100-150KG, while the radiation-proof lead doors used in hospitals weigh about 300KG, which cannot be used. Requirements, the 90° door opener is installed on the wall with plastic expansion screws. This installation method can bear radial load but cannot bear dynamic axial load. The door body is too heavy, and its excessive inertia back and forth will easily cause the expansion screw to loosen. Then the door operator will fall off. One end of the 90° door opener is installed on the wall ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is: in order to solve the 90° door opener on the market at the present stage, the load is 100-150KG, while the radiation-proof lead door used in the hospital has a weight of about 300KG, which cannot meet the use requirements, and the 90° door opener The installation is all installed on the wall with plastic expansion screws. This installation method can bear radial load but cannot bear dynamic axial load. Because the door opener will have acceleration and deceleration states when it is used, and because the lead door is too heavy, its Excessive inertia back and forth will easily cause the expansion screw to loosen, and the door operator will fall off. One end of the 90° door opener is installed on the wall, and the other end is installed on the door. It is divided into two independent entities. In the heavy door system, the installation requirements are too high. High, even a slight inclination will cause too much resistance, and the door body cannot be opened and closed. Generally, the door body is required to be installed against the wall as much as possible, and the installation cannot be adjusted according to the wall thickness; from the perspective of radiation protection, the door body is generally installed in the center for protection. The effect is the best. Commonly used door operators cannot meet this requirement. Therefore, a heavy-duty 90° door operator with adjustable installation position is proposed.
