A height adjustment device with damping effect

Abstract

The invention provides a height adjusting device with a damping effect. The device mainly comprises an upper adjusting rod, a lower supporting rod, a spring buckle and a locking mechanism. The upper adjusting rod is a hollow sectional material with a groove, integrally penetrates through the lower supporting rod and can slide up and down in the lower supporting rod. The lower supporting rod supports the upper adjusting rod, the spring buckle and the locking mechanism. The spring buckle is assembled in the groove of the upper adjusting rod in a compression state, the friction force between thebuckle and the groove is adjusted through tension of a belleville spring, and accordingly the damping adjusting effect is achieved. The locking mechanism is connected with the spring buckle, and the whole device is locked after adjustment is conducted in place. According to the device, the upper adjusting rod slides in the lower supporting rod with the damping effect, and accordingly height adjustment is achieved; locking is achieved after adjustment is conducted in place, and relative sliding is prevented; and in addition, a wire harness and other similar structures can penetrate through theinterior of the whole device, and electrical connection can be achieved during sliding.

Description

technical field [0001] The invention relates to a height adjustment device, in particular to a height adjustment device with a damping effect. Background technique [0002] The height adjustment device is a device with a very high usage rate in various equipment, such as speech equipment, photographic equipment, teleprompters, microphones, etc. In order to prevent the supported structure from sliding down when it is loosened, the height adjustment device needs a damping structure. In most cases, the structure of the adjustment device with a damping structure will be more complicated, and the application will be greatly limited. [0003] In addition, electrical equipment such as speech equipment, photographic equipment, teleprompters, and microphones need additional structures such as wiring harnesses when using existing height adjustment devices for height adjustment. These wiring harness structures are externally placed outside the entire electrical equipment, which will af...
