Embodiment Construction

[0011] A labor-saving lifting mechanism, comprising an outer gantry 1 and an inner gantry 2, the left and right vertical arms 3, 4 of the inner gantry are respectively inserted into the left and right vertical arms 5, 6 of the outer gantry, The left and right vertical arms of the inner gantry are respectively provided with a pulley mechanism 7 that is in sliding contact with the inner wall of the left and right vertical arms of the outer gantry; The reels are connected to one end of the left and right traction belts 9 and 10, and the other ends of the left and right traction belts are fixedly connected to the lower parts of the respective left and right vertical arms after passing through the respective roller mechanisms; Or reverse, the left and right traction belts are simultaneously drawn in or released, thereby driving the left and right vertical arms of the gantry to rise or fall simultaneously along the outer gantry.

[0012] The pulley mechanism is a sliding bearing mec...

Abstract

The invention discloses a labor-saving lifting mechanism. A left vertical arm and a right vertical arm of an internal n-shaped rack are inserted in a left vertical arm and a right vertical arm of an external n-shaped rack respectively, and pulley mechanisms in sliding contact with the inner walls of the left and right vertical arms of the external n-shaped rack are arranged on the left and right vertical arms of the internal n-shaped rack respectively; a traction belt rolling wheel is arranged in a cross arm of the external n-shaped rack and connected with one end of a left traction belt and one end of a right traction belt, and the other end of the left traction belt and the other end of the right traction belt are fixedly connected with the lower portions of the left and right vertical arms through respective wheel supporting mechanisms respectively; through forward rotation or reverse rotation of the traction belt rolling wheel, the left and right traction belts are rolled or released at the same time, and accordingly the left and right vertical arms of the n-shaped racks are driven to ascend or descend along the external n-shaped rack at the same time. The labor-saving liftingmechanism is reasonable in structure, convenient to use, good in labor-saving performance and particularly suitable for lifting mechanisms of vertical office computer tables; through pulley mechanisms, certain gaps between the vertical arms of the internal n-shaped rack and the vertical arms of the external n-shaped rack are kept, and the vertical arms cannot be collided and damaged.

Description

technical field [0001] The invention relates to a lifting mechanism. Background technique [0002] Existing vertical office computer desks have various types of elevating mechanisms, but the general labor-saving performance is not ideal and needs to be further improved. Contents of the invention [0003] The object of the present invention is to provide a labor-saving lifting mechanism that is easy to use and has good labor-saving performance. [0004] Technical solution of the present invention is: [0005] A labor-saving lifting mechanism, which is characterized in that it includes an outer gantry and an inner gantry, the left and right vertical arms of the inner gantry are respectively inserted into the left and right vertical arms of the outer gantry, and the inner gantry The left and right vertical arms of the outer gantry are respectively provided with pulley mechanisms slidingly contacting the inner walls of the left and right vertical arms of the outer gantry; O...
