DETAILED DESCRIPTION

[0021] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a lifting workbench for mechanical maintenance, comprising a support frame 1, an electric telescopic rod 2 is fixed to the inner side of the support frame 1, a placement plate 3 is fixed to the top of the electric telescopic rod 2, the placement plate 3 can be used to place and repair the machine, and the height of the placement plate 3 can be adjusted by starting the electric telescopic rod 2, so as to facilitate workers of different heights to repair the machine, an extension mechanism 4 is arranged at the bottom of the placement plate 3, and a stabilizing mechanism 5 is arranged on the support frame 1.

[0022] Specifically, the extension mechanism 4 includes a threaded rod 41, a knob 42, a threaded sleeve 44, a hinge block 45, a movable rod 46 and an extension plate 43; the bottom of the placement plate 3 is rotatably installed with the threaded rod 41, the bottom of the threaded rod 41 is fixed with a knob 42, the outer wall of the threaded rod 41 is threadedly connected with a threaded sleeve 44, and then when the knob 42 is rotated, the threaded sleeve 44 can be moved on the threaded rod 41, and the bottom of the placement plate 3 is slidably installed with an extension plate 43, the bottom of the extension plate 43 is fixed with a hinge block 45, the bottom of the hinge block 45 is hinged with a movable rod 46, and the movable rod One end of 46 away from the hinge block 45 is hinged on the threaded sleeve 44, and two groups of extension plates 43 are provided, and the two groups of extension plates 43 are symmetrically arranged with the center line of the placement plate 3 in the vertical direction as the symmetry axis. When the threaded sleeve 44 moves upward on the threaded rod 41, the threaded sleeve 44 can squeeze the movable rod 46, and the hinge block 45 can be squeezed and moved through the movable rod 46, so that the two groups of extension plates 43 can be moved out from the bottom of the placement plate 3, thereby increasing the placement area of ​​the machine, facilitating the placement and maintenance of more machines, and improving the practicality of the device.

[0023] Specifically, the stabilizing mechanism 5 includes a slider 51, a return spring 52, a connecting rod 53, a suction cup 54, an extrusion rod 55, an inclined block 56, a transmission rod 57 and a push rod 58; a slider 51 is slidably installed in the support frame 1, and two groups of sliders 51 are provided, and the two groups of sliders 51 are symmetrically arranged with the center line of the support frame 1 in the vertical direction as the symmetry axis, a return spring 52 is fixed to the top of the slider 51, and the top of the return spring 52 is fixed to the inner side of the support frame 1, and the return spring 52 can be provided to reset the slider 51, a connecting rod 53 is fixed to the bottom of the slider 51, a suction cup 54 is fixed to the bottom of the connecting rod 53, four suction cups 54 are provided, and two suction cups 54 form a group, and the two groups of suction cups 54 are symmetrically arranged with the center line of the support frame 1 in the vertical direction as the symmetry axis, an extrusion rod 55 is fixed to the bottom of the extension plate 43, and an inclined block 56 is slidably installed at the bottom of the placement plate 3, and the inclined block 56 is provided There are two groups, and the two groups of inclined plane blocks 56 are symmetrically arranged with the center line of the support frame 1 in the vertical direction as the symmetry axis. When the extension plate 43 is moved out from the bottom of the placement plate 3, the extrusion rod 55 will squeeze the inclined surface of the inclined plane block 56, which will cause the inclined plane block 56 to be squeezed, so that the two groups of inclined plane blocks 56 are moved away from each other. A transmission rod 57 is fixed to the bottom of the inclined plane block 56, so that the inclined plane block 56 can drive the transmission rod 57 to move. A push rod 58 is hinged at the bottom of the transmission rod 57, and one end of the push rod 58 away from the transmission rod 57 is hinged on the slider 51. When the transmission rod 57 approaches the support frame 1, the transmission rod 57 will squeeze the push rod 58, so that the push rod 58 pushes the slider 51 to move downward. Through the connecting rod 53, the suction cup 54 can be adsorbed on the ground, thereby improving the stability of the device, preventing too many things from being placed on the placement plate 3 and the extension plate 43, resulting in poor stability of the device and affecting the maintenance effect of the staff.

[0024] Working principle: When the knob 42 is turned, the threaded sleeve 44 can be moved on the threaded rod 41. When the threaded sleeve 44 moves upward on the threaded rod 41, the threaded sleeve 44 can squeeze the movable rod 46. The movable rod 46 can squeeze the hinge block 45 to move, so that the two groups of extension plates 43 can be moved out from the bottom of the placement plate 3, thereby increasing the placement area of ​​the machine, facilitating the placement and maintenance of more machines, and improving the practicality of the device. When the extension plate 43 is not needed, the threaded sleeve 44 can be moved downward on the threaded rod 41 by reversing the knob 42. The two groups of extension plates 43 can be extended to the bottom of the placement plate 3 through the movable rod 46 and the hinge block 45, and then can be stored.

[0025] When the extension plate 43 is moved out from the bottom of the placement plate 3, the squeezing rod 55 will squeeze the inclined surface of the inclined surface block 56, which will squeeze the inclined surface block 56 and move the two groups of inclined surface blocks 56 away from each other, so that the inclined surface block 56 can drive the transmission rod 57 to move. When the transmission rod 57 approaches the support frame 1, the transmission rod 57 will squeeze the push rod 58, so that the push rod 58 pushes the slider 51 to move downward. Through the connecting rod 53, the suction cup 54 can be adsorbed on the ground, thereby improving the stability of the device and preventing too many things from being placed on the placement plate 3 and the extension plate 43, resulting in poor stability of the device and affecting the maintenance effect of the staff. When the extension plate 43 is extended into the placement plate 3, the squeezing rod 55 will not squeeze the inclined surface block 56. Through the reset spring 52, the slider 51 can drive the connecting rod 53 to move upward, so that the suction cup 54 is away.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
