Problems solved by technology

In practical applications, it is found that due to reasons such as air sources, the left and right shut-off doors sometimes cannot run synchronously. When one shut-off door is completely closed, the other shut-off door cannot be completely closed. If the force is large, the fully closed shut-off door squeezes the door-opening booster, which may cause the door-opening booster to be twisted, deformed, or even pushed to the other side, resulting in the door-opening booster being unable to use

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, the present invention includes a frame 1, a door panel 2, an insertion rod 5, a booster rod 9, a booster cylinder 10, a piston rod 11, etc., and the insertion rod 5 is connected to the piston rod 11 of the booster cylinder 10 through the booster rod 9.

[0012] combine figure 2 As shown, two opposite guide seats 3 are set on the frame 1 perpendicular to the moving direction of the door panel 2, and a guide ring 8 is set on the bottom surface of the frame 1. The guide seat 3 is provided with a guide groove 4, and the guide ring The inner diameter of 8 is slightly larger than the maximum diameter of the booster rod 9, the upper end of the insertion rod 5 is inserted into the guide frame 7, fixed on the guide frame 7 with the fixing device 6, and the guide frame 7 takes the insertion rod 5 in the guide groove 4 and guides Move within r...

Abstract

The invention discloses an improved door opening booster which solves the problem that an existing device is prone to deformation when being squeezed. The improved door opening booster is characterized in that a guide ring is arranged on the bottom face of a frame, and the inner diameter of the guide ring is slightly larger than the largest diameter of a boosting rod; two opposite guide seats are disposed on the frame perpendicular to the moving direction of a door sheet; guide grooves are formed in the guide seats, and a guide frame is arranged between the guide grooves; the upper end of an insertion rod is inserted in the guide frame and fixed to the guide frame through a fixing device; the guide frame drives the insertion rod to move up and down in the guide grooves and the guide ring. The guide seats and the guide ring are used for locating the insertion rod, and the insertion rod is prevented from distorting and deforming when squeezed by a shut-off door.

Description

technical field [0001] The invention relates to a device for assisting in opening a door, in particular to a door opening booster for closing a door. Background technique [0002] The applicant has applied for a patent named two-way pneumatic hot air shut-off door (application number 2015204075350), which involves a door opening booster. In practical applications, it is found that due to reasons such as air sources, the left and right shut-off doors sometimes cannot run synchronously. When one shut-off door is completely closed, the other shut-off door cannot be completely closed. If the force is large, the fully closed shut-off door squeezes the door-opening booster, which may cause the door-opening booster to be twisted, deformed, or even pushed to the other side, making the door-opening booster unusable. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide an improved door opening booster ...
