Abstract

The invention relates to the technical field of office home furnishing, and discloses an office drawer slide rail for controlling speed by using a magnetorheological fluid. The office drawer slide rail comprises a sliding rail body, the outer side wall of the sliding rail body is rotatably connected with a pulley, the inner side wall of the pulley is fixedly connected with an inner wheel, and a first electromagnet is fixedly connected between the inner wheel and the pulley, and an inner rotating shaft is rotatably connected to the central position of the interior of the inner wheel. Current generated on the coils on the two sides of the pulley is increased accordingly, the magnetic field generated on the first electromagnet connected with the coils is increased accordingly, the magnetorheological fluid becomes viscous according to the increase of the magnetic field, the shear stress of the damping plate on the inner rotating shaft for overcoming the is increased accordingly, thereforethe rotating speed of the inner rotating shaft is reduced, and the rotating speed of the corresponding pulley is also reduced, so that the sliding speed of a sliding plate in contact with the pulley is also reduced, the purpose of reducing the impact force is achieved, and the drawer is effectively protected from being damaged by excessive impact force.

Description

technical field

[0001] The invention relates to the technical field of office and home furnishing, in particular to a slide rail for office drawers controlled by magnetorheological fluid. Background technique

[0002] There are many kinds of existing office furniture, and the most common ones are writing desks and cabinets. Drawers are more commonly used in writing desks and cabinets. Common drawers need to be drawn and pulled by users themselves. To realize the storage and retrieval of items, wherein, the drawers are usually fixed on the table body with slide rails and pulleys, so that they can slide on the table body.

[0003] As a new material, magnetorheological fluid can change its shape according to the change of the magnetic field. In the prior art, the drawer is usually directly fixed on the table body with slide rails and pulleys. When the drawer is pulled out or put in When using too much force on the table body, the drawer will be quickly pulled out or retracted ...

Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] see Figure 1-5 , a slide rail for an office drawer that uses magnetorheological fluid to control the speed, including a slide rail 1, the outer wall of the slide rail 1 is slidably connected with a slide plate 5, the slide plate 5 is located between two pulleys 2, and the slide plate 5 is used for Because it is connected with the drawer body, the drawer body drives the sliding plate 5 to slide between the two pulleys 2, the outer wall of the slide rail...
