Adjustable manual lifting table

Abstract

The invention relates to the technical field of lifting tables, in particular to an adjustable manual lifting table. The adjustable manual lifting table is characterized in that the upper end of a cross beam is connected with a working table top, and the left side and the right side of the lower end of the cross beam are connected with a left lifting table leg assembly and a right lifting table leg assembly respectively; a driving spring is arranged on one side in the cross beam, one end of the driving spring is connected with one end of a cam disc driving rope, and the other end of the cam disc driving rope is connected with a cam disc assembly; the other end of the driving spring is connected with a spring tension regulator; and one end of a driving steel wire rope and one end of an auxiliary steel wire rope are wound on the cam disc assembly in opposite directions, the other end of the driving steel wire rope is divided into two paths which are respectively connected with one ends of a left driving rope and a right driving rope, and the other end of the auxiliary steel wire rope is divided into two paths which are respectively connected with a left auxiliary rope and a right auxiliary rope. Compared with the prior art, the height of the table top can be continuously adjusted, time and labor are saved in the operation process, and the table is widely used in offices, families and the like.

Description

technical field [0001] The invention relates to the technical field of lift tables, in particular to an adjustable manual lift table. Background technique [0002] The usual way of working is fixed-height desks, where employees sit and sit in a relatively fixed posture. Over time, it will cause symptoms such as back pain, shoulder and neck discomfort, and serious health problems. Currently, the height-adjustable height-adjustable desks on the market are generally electric desks, because of their power requirements, the application occasions are relatively limited. [0003] At present, there are many ways to realize the lifting of the manual lifting table. The more common way is to use the handle to shake, and the relative rotation of the screw structure through the transmission device will cause relative displacement, thereby changing the height of the desktop and adjusting it. It is labor-saving but the adjustment speed is slow. And the mechanism needs to be maintained mor...

Problems solved by technology

[0003] At present, there are many ways to realize the lifting of the manual lifting table. The more common way is to use the handle to shake, and the relative rotation of the screw structure through the transmission device will cause relative displacement, thereby changing the height of the desktop and adjusting it. It is labor-saving but the adjustment speed is slow. And the mechanism needs to be maintained more frequently, otherwise it is easy to rust or get stuck, and it takes more physical strength to lift the desktop; and the angle of the corresponding structure can be changed through the latch and the rotating mechanism, thereby changing the height of the desktop, but it is more inconvenient. The tightness will have certain dangers, the adjustment speed is slow, and generally only discrete gears can be set; there are also those who directly use the preset jacks and pins to change the height of the tabletop. Although the structure is simple, there are only a limited number of discrete gears. The location is available, and the operation is dangerous, and there are certain requirements for the user's physical strength
