Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
As shown in fig. 1 to 4, the liftable drawer includes:
a drawer body 1 for holding articles;
the drawer frame 2 is an installation foundation of the drawer body 1;
four guide rails 3 are arranged on the inner walls of the two sides of the drawer frame 2 in parallel, and two guide rails are arranged on each side. The guide rail 3 of this embodiment is a telescopic guide rail, and has a plurality of telescopic rods 31 which are sequentially sleeved inside and outside, and the telescopic rods can slide relatively under the action of external force.
The connecting mechanism 5 is connected between the bracket 4 and the drawer body 1 and can drive the bracket 4 to slide along the guide rail 3 along with the drawing of the drawer body 1; comprising a first hinge rod 51, a second hinge rod 52, a pull rod 53, a connecting piece 54 and a connecting rod 55.
Wherein the pull rod 53 has a T-shaped structure;
the first ends of the first hinging rod 51 and the second hinging rod 52 are respectively hinged to two end parts of the connecting rod 55, and the connecting rod 55 is connected to the telescopic rod 31 at the outermost end of each guide rail; the other ends of the first hinging rod 51 and the second hinging rod 52 are respectively hinged on the two ends of the vertical rod part of the pull rod 53;
the connecting member 54 in this embodiment is a pneumatic spring, and both ends thereof are connected to the middle portion of the link lever 55 and the other end portion of the first hinge lever 51, respectively.
The links of the four hinge points between the link 55, the first hinge lever 51, the second hinge lever 52 and the vertical portion of the tie rod 53 constitute a parallelogram.
The two tie rods 53 are respectively fixed on the outer walls of both sides of the drawer body 1 and can move along with the movement of the drawer body.
The positioning assembly is arranged between the drawer body 1 and the drawer frame 2 and is used for positioning the drawer body 1 when the drawer body 1 changes in height so as to prevent the drawer body 1 from being separated from the drawer frame 2; comprising an electromagnet 61 and a magnetic conductive member 62; in this embodiment, the electromagnet 61 is disposed on the drawer frame 2, and the magnetic conductive member 62 is an iron block and is disposed on the tail plate of the drawer body 1. The electromagnet can also be arranged on the drawer body, and the magnetic conduction piece is arranged on the drawer frame.
The working principle of this embodiment is described as follows:
when the drawer body is pulled open, the connecting mechanism moves along with the movement of the drawer body to drive the guide rail to extend outwards; when the connecting mechanism begins to be exposed out of the drawer frame, the two hinging rods move downwards under the action of self gravity of the drawer body, the drawer body falls down, when the telescopic rod stretches to the maximum length, the drawer body is completely exposed out of the drawer frame, the drawer body is completely opened, and the drawer body falls down to the lowest position under the action of self gravity; at this time, the electromagnet is electrified; the drawer body is lifted by hand gently, under the auxiliary effect of the pneumatic spring, the position of the drawer body can be lifted by small force, when the magnetic conduction piece touches the electromagnet, the magnetic conduction piece and the electromagnet are attracted, the drawer body is locked at the highest position, at the moment, the pneumatic spring also provides a certain supporting force for the drawer body, the pulling force of the drawer body to the positioning component is reduced, and people can conveniently take and put articles.
When the use is finished, the electromagnet is powered off, the drawer body slowly descends to the lowest position under the action of self weight and the starting spring, the drawer body is pushed, the guide rail is retracted, and the two hinging rods on the connecting mechanism are gradually deformed and restored along with the retraction of the drawer body until the drawer body is closed.
