a blocker

Abstract

The invention discloses a stopper. The stopper comprises an air cylinder, a connecting rod mechanism and a blocking part; one end of the connecting rod mechanism is fixedly connected with a piston rod of the air cylinder; the blocking part is fixedly connected with the other end of the connecting rod mechanism; when the blocking part is affected by external force, the connecting rod mechanism moves to enable the piston rod to move; and when the external force of the blocking part is evacuated, the air cylinder drives the piston rod to reversely move, and the blocking part returns to the original position. According to the stopper, stress of the air cylinder is reduced, and the air cylinder is not prone to being damaged, so that the problem that an air cylinder rod is directly stressed and is likely to be damaged is solved, and the stopper is more stable and reliable.

Description

technical field [0001] The invention relates to a mechanical structure on a production line, in particular to a stopper. Background technique [0002] At present, household air-conditioning assembly lines generally use QX-2 series stoppers. The assembly line stopper structure is fixedly installed between the flow tracks of the production line. The rollers and the cylinder play the role of buffering and blocking. When the process needs to be released, the cylinder stretches out and turns the baffle to lie horizontally, so that the tray on the assembly line can be driven into the next process. [0003] The blockers in the prior art have the following problems during use: [0004] 1. Due to the large force and frequent failures, the cylinder itself and the fixed seat are abnormally many; [0005] 2. Due to a single point of force, when the product is not centered on the assembly line, it will fall due to obstruction; [0006] 3. Because the force-bearing surface of the stopp...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the large force and frequent failures, the cylinder itself and the fixed seat are abnormally many;

[0005] 2. Due to a single point of force, when the product is not centered on the assembly line, it will fall due to obstruction;

[0006] 3. Because the force-bearing surface of the stopper is small and small, when there are too many stackers on the assembly line, the force is too large, the stopper cannot be retracted and released normally, and the small plastic rollers are easily deformed and damaged, and the surface is damaged when the packing box is soft;

[0007] 4. Long-term use has high faults, frequent maintenance and high cost of spare parts
