Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1, 2, 3 and 4, the hand-electric-mechanical opening and switching device for a cultural relic showcase comprises a showcase 1, a motor 2 is installed at the bottom of the showcase 1, an output shaft of the motor 2 is provided with a driving wheel 3, a mounting shaft 31 is arranged on the front side of the driving wheel 3, the driving wheel 3 is connected with a driving wheel 4 through the mounting shaft 31, a transmission shaft 5 is installed on the rear side of the driving wheel 4, a driven sprocket 6 is installed at the rear end of the transmission shaft 5, a chain 7 is installed on the driven sprocket 6, a glass door connecting device 8 is installed on the chain 7, the glass door connecting device 8 is connected with a glass door of the showcase, a bolt 9 is installed on the transmission shaft 5, a steel wire 10 is connected on the bolt 9, and the front end of the steel wire 10 is connected to a handle 11.

As shown in fig. 4, two mounting shafts 31 are provided, and are symmetrically disposed at two ends of the front side of the driving wheel 3. Mounting holes 41 are formed in two sides of the driving wheel 4, the mounting holes 41 are formed in positions corresponding to the mounting shafts 31, and the two mounting shafts 31 are inserted into the two mounting holes 41 respectively.

As shown in fig. 3, the plug 9 is installed on the top of the driving shaft 5, and the steel wire 10 is wound around the plug 9.
