Light door opening and supporting mechanism

Abstract

The invention provides a light-duty door opening support mechanism, comprising: a pipe body, an elastic component fixed on the wall of the pipe body, and a limit shaft located in the pipe body, the second end of the limit shaft is composed of an extrusion section, a limit The extruding section is a ring-shaped convex structure, and its outer diameter and the outer diameter of the matching section are larger than the outer diameter of the limiting section; the spring is arranged in the elastic box and blocked by the limiting head. Those constitute elastic components. When opening, the limit shaft moves forward under the opening force of the light door. When the limit head passes through the extrusion section and snaps into the limit section, the limit shaft stops moving to realize the limit of the light door. Compared with the prior art, the present invention cancels the high-pressure working gas, reduces energy consumption and production cost, eliminates the influence of ambient temperature on the opening support function, and the reaction force received by the light-duty door in the closed state, and at the same time reduces the The limitation of installation layout improves the versatility.

Description

technical field [0001] The invention belongs to the technical field of light lift doors, and in particular relates to a light door opening support mechanism. Background technique [0002] In the prior art, the gas strut type structure is mostly used for the support limit of the light lift door, that is, the support force is formed by the pressure of the high-pressure gas inside the support structure, and the support point is mostly at the apex of the support mechanism. figure 1 It is a schematic diagram of the support state after the light door is opened. As shown in the figure, one end of the gas strut 1' is connected to the light door 3' with a hinge 2', and the other end is connected to the fixed base 4', and the base 4' passes through The hinge 2' is connected with the light door 3', and the maximum elongation position of the gas strut 1' is its working position, where the opened light door 3' is limited and supported. [0003] Figure 2a-2b It is a schematic diagram o...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the use of high-pressure gas to fill the cavity, special mechanical equipment is required to produce the gas-strut structure, and the production energy consumption is high;

[0005] 2. When the light door is closed, the supporting force formed by the air pressure in the inner cavity and the area difference between the left and right side panels will produce a continuous reverse force on the connected parts, resulting in continuous force on the light door and hinges. produce deformation;

[0006] 3. The support force formed by the air pressure in the inner cavity and the area difference between the left and right side panels is a normal opening force, which needs to be overcome when closing the door, so there is a problem of relatively large closing force;

[0007] 4. When the existing gas strut structure is arranged in the door system, in order to ensure that the door is in a normally closed state and has no normal opening force, it is necessary to consider the system between the hinge axis, the gas strut axis, and the locking point of the locking mechanism. Self-locking relationship, the limitation of design layout is relatively large;

[0008] 5. Since the gas that provides the working force is easily affected by the ambient temperature, there are large differences in the output force under different temperature environments, which affects the stability of the work
