Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art all belong to the protection scope of the present invention.

As shown in the figure, the utility model discloses a work show shelf is used in occupation training, include: the display frame comprises a mounting base plate 1, lifting support legs 2, a linear electric cylinder 3 and a display frame 4, wherein the lifting support legs 2 are rotatably mounted on the mounting base plate 1, one ends of the lifting support legs 2 are slidably mounted on the side wall surface of the mounting base plate 1, the lifting support legs 2 are bridged between the two side walls of the mounting base plate 1, the power ends of the linear electric cylinder 3 are sleeved with the sliding ends of the lifting support legs 2, the top surfaces of the lifting support legs 2 are mounted at the bottom of the display frame 4, the linear electric cylinder 3 pushes the bottom of the lifting support legs 2, and the lifting support legs 2 stretch out and draw back to drive the display frame 4 mounted on the top surfaces of the lifting support legs 2 to lift.

In this embodiment, the mounting base plate 1 includes: bottom plate 11, slip eaves 12 and sliding tray 13, slip eaves 12 fixed mounting in bottom plate 11 both sides wall face, sliding tray 13 sets up on slip eaves 12.

In this embodiment, the lifting leg 2 includes: the device comprises a first cross frame 21 and a second cross frame 22, wherein the fixed top of the first cross frame 21 is rotatably connected with the bottom of the second cross frame 22.

In the present embodiment, the first cross 21 includes: first slip end 211, first rotation end 212 and first slip end connecting rod 213, first slip end 211 with sliding tray 13 cooperatees, fixed mounting has between the first slip end 211 first slip end connecting rod 213, first slip end connecting rod 213 slidable mounting be in the sliding tray 13, first slip end connecting rod 213 with the power end fixed connection of sharp electric jar 3, first rotation end 212 rotates and installs between the slip eaves 12.

In this embodiment, the two side wall surfaces of the bottom of the display frame 4 are provided with the bearing sliding chutes 41 with the same specifications as the sliding chutes 13, and the bearing sliding chutes 41 and the first cross 21 are connected with the installation bottom plate 1 in the same manner.

The working principle is as follows:

first, since the linear electric cylinder 3 is fixedly installed on the installation base plate 1, and the power end of the linear electric cylinder 3 is fixedly connected to the first sliding end connection rod 213, when the power end of the linear electric cylinder 3 pushes, the first sliding end connection rod 213 is driven by the linear electric cylinder 3 to move linearly in the horizontal direction. Since the first sliding end connecting rod 213 is slidably fitted in the sliding groove 13, the first rotating end 212 is rotatably connected to the end of the sliding visor 12, and the first cross 21 is deformed as the first sliding end connecting rod 213 moves. Meanwhile, due to the rotational connection between the second cross 22 and the first cross 21, the deformation of the first cross 21 occurs while the second cross 22 changes synchronously with the deformation of the first cross 21. Because the connection mode between the top surface of the second cross frame 22 and the bearing sliding groove 41 is the same as the connection mode between the first cross frame 21 and the mounting base plate 1, after the second cross frame 22 deforms, the height of the display frame 4 in the vertical direction changes, and the display device placed on the display frame 4 is driven to move up and down according to the principle.

Wherein, because the slow motion of sharp electric jar 3 drives lift landing leg 2 and takes place deformation slowly, show frame 4 does not produce vibrations ground slow lifting in the middle of this process, does not influence the device of placing on show frame 4, has avoided the damage of device.

Meanwhile, the linear electric cylinder 3 is only required to be controlled to drive the whole device to move in the vertical direction, and manual operation is avoided.

The utility model provides a pair of work show shelf is used in vocational training drives 2 the decline that rise of lift landing leg through the motor, sets up lift landing leg 2 into parallelogram unstable structure, thereby utilizes 2 deformations of lift landing leg to make the show shelf the displacement in vertical side. Meanwhile, the motor converts the rotary power into linear propulsion, and the lifting support legs 2 are used for bearing the linear propulsion to realize lifting, so that manual operation is replaced, the moving speed is slow, and the damage of devices is prevented.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention should be included in the scope of the present invention.
