Protection mechanism for preventing desktop from descending under stress

Abstract

The invention discloses a protection mechanism for preventing a desktop from descending under stress. The protection mechanism comprises an upper upright column, a lower upright column, an upper pulley, a lower pulley, an elastic component, a first stay and a second stay. The upper upright column can be slidably inserted in the lower upright column, the upper pulley is rotatably positioned on the side walls of the upper end of the upper upright column, the lower pulley is rotatably positioned on the side walls of the lower end of the upper upright column, the upper end of the elastic component and the side walls of the upper end of the upper upright column are fixedly positioned, the elastic component can be elastically extended and retracted along the axial direction of the upper upright column under stress, upper end of the first stay and the upper end of the second stay are respectively fixedly connected with the upper pulley, the first stay and the second stay are respectively wound on the surface of the upper pulley in opposite directions by certain distances and then are led out of the upper pulley, the lower end of the first stay and the lower end of the elastic component are positioned in a fastened manner, and the lower end of the second stay is wound through the lower pulley to be connected with the lower upright column. The protection mechanism has the advantage that people can easily adjust the height of the desktop by the aid of the protection mechanism, and the protection mechanism is safe in use.

Description

technical field [0001] The invention relates to a height-adjusting mechanism of a table top which can be lifted and lowered, in particular to a protection mechanism for preventing the table top from falling under force. Background technique [0002] At present, in order to adapt to people of different heights using computer desks, study desks, etc., the height of the desktop is made into an adjustable structure. When adjusting the height of the desktop, due to the large gravity of the desktop itself and the items placed on the desktop, a large force is required to overcome the gravity of the desktop, which brings difficulties to the height adjustment of the desktop. If the holding force is not large enough, the desktop will fall rapidly, damage the desktop and the items on it, and even cause injury to the user. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides an anti-falling protection mechanism of the tab...

[0002] At present, in order to adapt to people of different heights using computer desks, study desks, etc., the height of the desktop is made into an adjustable structure. When adjusting the height of the desktop, due to the large gravity of the desktop itself and the items placed on the desktop, a large force is required to overcome the gravity of the desktop, which brings difficulties to the height adjustment of the desktop. If the holding force is not strong enough, it will cause the desktop to fall quickly, damage the desktop and the items on it, and even cause the user to be injured
