A mechanical self-starting device for an anti-vibration bed

Abstract

The invention relates to a mechanical self-starting device of an anti-vibration bed and a using method thereof. The technical solution is: a base is fixed at the bottom of the inner cavity of the box body, and the base supports the tray assembly above through a balance pillar placed longitudinally. The upper part of the tray assembly is a tray, and two or two trays are placed in the tray The above bearing steel balls are connected to the center of the tray to start the pull wire, and the start pull wire passes through the support pulley and passes through the positioning sleeve on the upper part of the side wall of the box to be connected to the drag support assembly. The beneficial effect is that the center of gravity is shifted by a plurality of bearing steel balls due to the shaking caused by the earthquake and thus rolls in an eccentric direction, driving the tray assembly to fall, thereby starting the anti-seismic bed body; in addition, the tray assembly falls, causing the The wire rope drives the start lever to move, so that the dragging square iron bar is dragged downwards. At this time, the triangular support plate of the dragging support assembly loses its fulcrum and rotates downwards, and then the falling bed board and mattress slide down quickly to realize the start of the shock-resistant bed body. .

Description

Technical field [0001] The invention relates to an anti-vibration starting device and method, in particular to a mechanical self-starting device of an anti-vibration bed and a method of use. Background technique [0002] There are many kinds of existing beds, but when the earthquake strikes, it is impossible to protect your life safely, which brings a lot of inconvenience to the later rescue work. Many trapped people did not die in the later period of the earthquake, but they were stuck in the corners of the ruins, but the shaking of the aftershocks allowed many living beings to leave this beautiful world forever. In the search and rescue process, many trapped people were injured by rough machinery. Also lost the only hope of survival. If people can fall into a safe and defensive seismic bed during an earthquake, it will bring great protection to survival, will reduce the difficulty of subsequent rescue work, increase the speed and efficiency of search and rescue, and will not c...

Problems solved by technology

It solves the problem of anti-shock to a certain extent, but its problem is that it needs a continuous power supply to make the control circuit control the movement of the bed body, which limits its application.

The problem is that it needs circuit control to start, and there is also the problem that self-starting cannot be realized when there is a power failure or no power

[0005] The Chinese patent document number is 204444978U, and the patent name is "self-starting mechanism of self-starting anti-shock life-saving life-saving bed". It is a plate-shaped structure that gradually becomes larger from top to bottom, and the hinge shaft of the suspension lug is set at its upper end, and the hinge shaft of the suspension lug is hinged at the head and tail of the shock-proof life-saving life-saving bed. The upper end of the suspension lug hinge shaft is provided with lap slots corresponding to the lap joints provided on the front and rear end surfaces of the middle plate; the vibration pickup used in it includes a box body, a gravity ball, a support column, an induction rope and a fixed pulley, and the box The body and the building are fixed together, the bottom and the middle of the box are provided with support columns, and the top surface of the support column is a concave hole matched with the gravity ball. Fixed pulley, the gravity ball is connected with the induction pull rope; the problem is: because a gravity ball is installed on the top of the support column, its sensitivity is not easy to adjust, and the effect is not good, so it cannot be adjusted; the suspension ear is connected through the vibration picker Realize self-starting, still can not meet the needs of the site
