Abstract

The invention discloses a mechanical stretching device. The mechanical stretching device comprises an adjusting rod (2), an adjusting piece (9), a stretching mechanism and a pull rod (6), wherein the adjusting piece (9) is arranged on the adjusting rod (2) in a sleeving manner and is in threaded connection with the adjusting rod (2); the stretching mechanism and the pull rod (6) are symmetrically arranged on two sides of the adjusting rod (2); the stretching mechanism comprises two connecting rods (4) of which one end parts are hinged; the other ends of the connecting rods (4) are respectively connected with the end part of the adjusting rod (2) and the adjusting piece (9); one end of the pull rod (6) is connected with the end part, far away from the adjusting rod (9), of one connecting rod (4); and a fixing piece (8) is arranged at the other end of the pull rod (6). The adjusting piece (9) is fixed, and the adjusting rod (2) is rotated, so that the axial movement of the adjusting piece (9) along the adjusting rod (2) can be converted into the movement of the pull rod (6) perpendicular to the axial direction of the adjusting rod (9), and the pull rod (6) moves outwards to be abutted tightly.

Description

technical field [0001] The invention discloses a mechanical stretching device, which belongs to the technical field of mechanical appliances. Background technique [0002] The push-pull structure is widely used in wardrobes, drawers, doors and windows and other fields because it does not take up space. The push-pull structure can actually be closed or opened by pushing and pulling the panel, which is more convenient to implement and use. However, when this structure is actually used, due to the sliding connection, the contact surface will be damaged as the use time prolongs, causing many horizontal push drawers or doors and windows to be difficult to open due to aging, requiring a large pulling force and small gaps. Humans can't bear the force very well and are easily injured. And the prior art does not have special-purpose utensil, need to stretch its end in the gap by thin block during actual operation, pry it open by moving thin block, but actually can cause the damage ...
