Abstract
The utility model relates to a weight-loss protecting switch, comprising a casing, a spring, a jacking block and a microswitch; wherein the spring is arranged on the bottom surface of the casing; the microswitch is arranged at the top; the jacking block is arranged between the microswitch and the spring and is supported by the spring (2). By adopting the structure, when the elevator goes wrong and falls vertically, microswitch controls the auxiliary safety measure to control the falling speed. The utility model has an advantage of safer effect.
Description
Technical field
The utility model relates to a kind of weightlessness switch.
Background technology
At present, people are the normal lift that uses in daily life, work, generally controls the speed of lifting by speed changer, for under the malfunctioning state of speed changer, or the cut-out of halliard, lift is hurtled down, jeopardize the loss of people's life and property.
Goal of the invention
The purpose of this utility model is to provide a kind of weightlessness switch that adopts mechanical structure control lift falling speed.
For achieving the above object, a kind of weightlessness switch of the present utility model, it is characterized in that: this switch is made up of housing, spring, roof pressure piece, sensitive switch, spring is located on the bottom surface of housing, sensitive switch is located at the top of housing, the roof pressure piece is located between sensitive switch and the spring, and by spring-loaded.
The further improvement project of the utility model for sensitive switch be provided with adjusting nut between housing is connected.
After adopting such structure, when lift breaks down and directly falls, just can control the auxiliary security measure and control falling speed, thereby obtain safer effect by sensitive switch.
Description of drawings
Fig. 1 is the structural representation of the concrete a kind of embodiment of the utility model.
Embodiment
Of the present utility model a kind of weightlessness switch as described in Figure 1, this switch is made up of housing 1, spring 2, roof pressure piece 3, sensitive switch 4, and spring 2 is located on the bottom surface of housing 1, and sensitive switch 4 is located at the top of housing 1, roof pressure piece 3 is located between sensitive switch 4 and the spring 2, and by spring 2 supportings; Sensitive switch 4 be provided with adjusting nut 5 between housing 1 is connected.During use, when lift hurtles down, roof pressure piece 3 is subjected to the effect of buoyancy and spring force, make the falling speed of the falling speed of housing 1 greater than roof pressure piece 3, the roof pressure piece is run into sensitive switch 4, promptly connects sensitive switch 4, the auxiliary security measure work that acquisition is connected from sensitive switch 4, force lift to slow down and stop to fall, thereby controlled the lift falling speed, guaranteed safety.
Claims (2)
1. weightlessness switch, it is characterized in that: this switch is made up of housing (1), spring (2), roof pressure piece (3), sensitive switch (4), spring (2) is located on the bottom surface of housing (1), sensitive switch (4) is located at the top of housing (1), roof pressure piece (3) is located between sensitive switch (4) and the spring (2), and is supported by spring (2).
