Problems solved by technology

[0002] Hangar doors and large factory doors are mostly manual sliding doors. Due to the uneven force of manual push and pull, the door travel speed is sometimes fast and sometimes slow. It will become faster and faster. At this time, it is impossible to control the deceleration or stop of the door body by manpower

Abstract

The invention discloses an overspeed braking bearing wheel for a manually-operated sliding door. The overspeed braking bearing wheel comprises a walking wheel, wherein the walking wheel is arranged ona walking wheel fixing seat; a ring bulge is arranged on the surface of the walking wheel; a plurality of grooves are formed in the equipartition positions of the circular bulge along the circumference; the ring bulge is divided into a plurality of equal segments by the grooves; a collision block is correspondingly arranged on one side of each groove; a dangling plate is arranged on the walking wheel fixing seat; the lower part of a mounting point of the dangling plate is arranged in a mode of floating on the surface of the walking wheel; a bump is connected to the middle part of the side, facing to the ring bulge, of the dangling plate. The overspeed braking bearing wheel disclosed by the invention has the advantages that a deceleration mechanism is added, so that the overspeed braking bearing wheel can slow down automatically when the speed of a door body is uneven, and further manual control is facilitated.

Description

Technical field: [0001] The invention relates to a load-bearing traveling wheel with overspeed braking for a manual sliding door. Background technique: [0002] Hangar doors and large factory doors are mostly manual sliding doors. Due to the uneven force of manual push and pull, the door travel speed is sometimes fast and sometimes slow. It will be faster and faster, and at this time, it is impossible to control the deceleration or stop of the door body by manpower. Invention content: [0003] The purpose of the present invention is to overcome the original shortcomings, and now add a deceleration mechanism, which can decelerate automatically when the running speed of the door body is uneven, which is convenient for manual control. [0004] The purpose of the present invention is achieved through the following technical solutions: a manual sliding door overspeed braking load-bearing travel wheel, including a travel wheel, the travel wheel is installed on the travel wheel ...
