Detailed Implementation

[0030] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0031] like Figures 1-7 As shown, a lifting storage rack base plate assembly serves as the base plate of the lifting storage rack. Specifically, the lifting storage rack includes a fixed frame and a movable frame that moves up and down relative to the fixed frame. A slide rail 15 is provided between the two. One end of a screw lifting assembly 16 is connected to a control box assembly 14, and the other end is connected to the movable frame. The screw lifting assembly 16 drives the movable frame to move up and down. The base plate assembly is located at the bottom of the movable frame and serves as its base plate. The bottom assembly includes an upper base plate 2 fixedly connected to the left and right side plates 13 and a lower base plate 3 movably connected to it via a switch assembly 5. The upper base plate 2 and the lower base plate 3 form a base plate body 1 with a cavity. There is at least one switch assembly 5, which is electrically connected to the control box assembly 14 that controls the movable frame. The switch assembly 5 is a touch switch. When the lower base plate 3 is touched, the switch assembly 5 transmits the received touch signal to the control box assembly 14. The control box assembly 14 realizes the lifting or stopping of the movable frame according to the switch signal transmitted by the switch assembly 5.

[0032] In the embodiment of the present application, the switch assemblies 5 are four, connected in parallel through the lines 6, and arranged in the cavity of the bottom plate body 1, and touch the surface of the lower bottom plate 3. The switch assemblies 5 transmit the touch signals received to the control box assembly 14, so as to realize the switch control of the switch assemblies 5. The switch assemblies 5 can also be one, two or even more, and the number of the switch assemblies 5 is determined according to the cavity volume of the bottom plate body 1, so that the switch assemblies 5 can be touched from all directions, and convenience is provided for the user.

[0033] The switch assembly 5 comprises a switch lower connecting plate 9, the switch lower connecting plate 9 is integrally provided with a switch mounting opening 17, and the switch 10 is arranged in the switch mounting opening 17. The upper end of the switch lower connecting plate 9 is further buckled with a switch upper connecting plate 7, and the spring 8 is arranged vertically between the two.

[0034] The switch lower connecting plate 9 is integrally provided with a boss 18 with a cavity 20, the boss 18 is reversely provided with a cavity 20, which can accommodate the gasket 11, and the inner wall of the boss 18 is further integrally provided with a through hole 19. The switch upper connecting plate 7 is integrally provided with a fixing column 21, the outer periphery of the fixing column 21 is integrally provided with a spring limiting edge 22. One end of the spring 8 is sleeved on the outer periphery of the boss 18 of the switch lower connecting plate, and the other end is accommodated in the spring limiting edge 22 of the switch upper connecting plate. The fixing column 21 integrally arranged on the switch upper connecting plate is inserted into the cavity 20 on the boss of the switch lower connecting plate, and then is fixed and connected with the gasket 11 by the screw 12. The switch lower connecting plate 9 is limited to move back and forth between the gasket 11 and the bottom of the fixing column. When the switch lower connecting plate 9 or the switch upper connecting plate 7 is pressed, the elastic force of the spring 8 can always make the two return to the initial position.

[0035] The switch lower connecting plate 9 is fixedly connected with the lower bottom plate 3, and the switch upper connecting plate 7 is fixedly connected with the upper bottom plate 2.

[0036] When the lower bottom plate 3 is pressed, the switch lower connecting plate 9 and the switch 10 accommodated in the switch mounting opening are driven to move close to the upper bottom plate 2. When the spring sheet of the switch 10 is extruded, the switch signal is sent out. When the pressure applied to the lower bottom plate 3 is removed, the spring 8 makes the switch lower connecting plate 9 and the lower bottom plate 3 return to the initial position.

[0037] In order to improve the strength of the lower bottom plate 3, the reinforcing strip 4 is fixedly connected to the lower surface of the lower bottom plate 3, and the switch lower connecting plate 9 can also be fixedly connected with the reinforcing strip 4.

[0038] Working principle: press the lower bottom plate, drive the switch lower connecting plate and the switch to move close to the upper bottom plate, until the switch sends out a signal, and the spring is extruded at the same time. The switch signal is transmitted to the controller through the connecting line. After receiving the signal, the controller drives the screw lifting assembly to drive the storage frame to rise or fall. Release the lower bottom plate, and the elastic force of the spring makes the lower bottom plate and the switch return to the initial position, waiting for the next operation.

[0039] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection required by the present application is defined by the appended claims and their equivalents.
