Manual lifting table

Abstract

The invention relates to a manual lifting table which comprises a first supporting component, a second supporting component and a table top, wherein the first supporting component and the second supporting component are fixedly connected with the table top; the manual lifting table further comprises a first power wire rope and a driving cabin fixedly connected with the table top; the first supporting component comprises a first inner tube, a first external tube and a first lifting rod; a first lifting pulley is arranged at a free end of the first lifting rod; a first power deflecting pulley is arranged at a fixed end of the first lifting rod; the first power wire rope is provided with a first input end and a first output end fixedly connected with the first inner tube; the first output end is fixedly connected with the first inner tube; the first power wire rope is connected with the first power deflecting pulley by striding across the first lifting pulley. The manual lifting table has the advantages that the height of the table top can be continuously regulated, the operation process is time-saving and labor-saving and the table top can be randomly adjusted to the required height and stopped at the required height.

Description

technical field [0001] The invention relates to a table, in particular to a manual lifting table. Background technique [0002] Nowadays, adjustable desks have been more and more widely used in life and work because of their ability to adjust the height of the desktop according to actual needs, such as lifting computer desks, lifting platform, lifting workbench and so on. Among them, according to the control method of lifting, it is mainly divided into electric lifting and manual lifting. The control and operation of the electric lifting table are relatively simple, and the lifting and braking can be started and stopped by motor control, but the electric lifting table is relatively expensive and heavy. It is relatively large and requires power consumption. Therefore, although the control of manual lifting tables is not as good as that of electric lifting tables, generally speaking, users do not have high requirements for control accuracy, so manual lifting tables are still w...

Among them, according to the control method of lifting, it is mainly divided into electric lifting and manual lifting. The control and operation of the electric lifting table are relatively simple, and the lifting and braking can be started and stopped by motor control, but the electric lifting table is relatively expensive and heavy. It is relatively large and requires power consumption. Therefore, although the manual lift table is not as good as the electric lift table in terms of control, generally speaking, users do not have high requirements for control accuracy, so manual lift tables are still widely used in various occasions.

[0003] There are many ways to realize the lifting and lowering 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, which is labor-saving but the adjustment speed is slow. More frequent maintenance is required, otherwise it is easy to rust or get stuck, and it takes more physical strength to lift and lower the desktop; there is also a way to change the angle of the corresponding structure through the latch and the rotating mechanism, thereby changing the height of the desktop, but it is more inconvenient. If it is not locked, it will It is dangerous, the adjustment speed is slow, and generally only discrete gears can be set; there are also those that directly use the preset jacks and pins to change the height of the desktop. Although the structure is simple, only a limited number of discrete gears are available. , and the operation is dangerous, and there are certain requirements for the physical strength of the user
