Description

Technical Field

[0001] This utility model relates to the field of backstop technology, specifically a non-contact backstop. Background Technology

[0002] A non-contact backstop is a special type of one-way clutch or check device. Its core feature is that when the equipment is working normally, the internal locking mechanical components remain physically non-contact with the rotating parts. Only when the equipment attempts to rotate in the opposite direction will these components move rapidly under the action of centrifugal force, gravity, or internal wedging mechanism, contact the rotating parts and lock them, preventing reverse rotation.

[0003] For example, Chinese patent application number 202123348994.0 discloses a non-contact backstop. The outer end cover has a slot on each of its upper and lower sides. A limiting rod is fixed to each of the upper and lower sides of the outer end face of the non-contact backstop body, and the two limiting rods are respectively embedded in the slots on the upper and lower sides. An L-shaped block is fixed to each of the left and right sides of the outer periphery of the non-contact backstop body. A telescopic rod is horizontally fixed to the vertical part of each L-shaped block facing the outer end cover. A mounting block is fixed to the end of each telescopic rod pointing towards the outer end cover. A spring is fitted onto the outside of each telescopic rod. An insertion rod is fixed to the end of each mounting block facing the outer end cover. Slots corresponding to the positions of the insertion rods are opened on the left and right sides of the outer end cover. The insertion rods are inserted into the slots on the same side, and at this time, the outer end cover is tightly against the non-contact backstop body. An L-shaped pull rod is fixed to the upper side of the outer periphery of each mounting block. This utility model has the advantages of convenient installation and simple maintenance.

[0004] However, in the aforementioned non-contact backstop, the connection points of the housing lack auxiliary reinforcement during use. Even minor deformations at these connections directly affect the overall geometric accuracy of the housing, leading to changes in the crucial internal working clearance. Therefore, those skilled in the art have provided a non-contact backstop to address the problems mentioned in the background section. Utility Model Content
