[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0027] Example 1:

[0028] Please refer to Figures 1-6. A laboratory shaker speed controller includes a controller body 1.

[0029] The controller body 1 has a first sliding groove 101 on its side wall, a first mounting groove 11 on its upper end, a moving component 12 inside the first mounting groove 11, and a protective component 2 on its upper end.

[0030] The protective component 2 includes a first protective plate 21 movably connected to the upper end of the controller body 1. A first movable frame 22 is provided at the lower end of the first protective plate 21. A first drive groove 221 is provided on the side wall of the first movable frame 22. A third mounting groove 23 is provided on the side wall of the first protective plate 21. A first connecting plate 231 is slidably connected to the inner wall of the third mounting groove 23. A second connecting plate 232 is movably connected to one end of the first connecting plate 231 via a pin. A third connecting plate 233 is movably connected to one end of the second connecting plate 232 via a pin. A fourth connecting plate 234 is movably connected to one end of the third connecting plate 233 via a pin. A second protective plate 24 is fixedly connected to one end of the fourth connecting plate 234. A second movable frame 25 is fixedly connected to the lower end of the second protective plate 24. A second drive groove 251 is provided on the side wall of the second movable frame 25. The first movable frame 22 and the second movable frame 25 are slidably connected to the inner wall of the first sliding groove 101, respectively.

[0031] As can be seen from the above, when the controller body 1 is not in use, the first protective plate 21 and the second protective plate 24 of the protective component 2 can protect the display screen and buttons on the controller body 1. When the controller body 1 needs to be used, the first connecting plate 231, the second connecting plate 232, the third connecting plate 233 and the fourth connecting plate 234, which are movably connected inside the third mounting slot 23, cooperate with each other to form a bracket with the first protective plate 21, supporting the controller body 1 which is tilted at a certain angle, making it convenient for the user to operate.

[0032] Example 2:

[0033] This embodiment is basically the same as the previous embodiment, except that the first mounting groove 11 has a second sliding groove 111, a third sliding groove 112, and a fourth sliding groove 113 on each of its non-adjacent side walls. The third sliding groove 112, the fourth sliding groove 113, and the first sliding groove 101 are connected. The moving component 12 includes a mounting frame 121 movably connected in the first mounting groove 11. A drive column 122 is fixedly connected to each of the non-adjacent side walls of the mounting frame 121. The drive column 122 is slidably connected to the inner wall at the port of the third sliding groove 112. A mounting plate 123 is fixedly connected to the lower end of the mounting frame 121. A first rotating column 124 is movably connected to the side wall of the mounting plate 123. A second rotating column 125 is movably connected to the side wall of the mounting frame 121. A roller 126 is movably connected to one end of both the first rotating column 124 and the second rotating column 125. The first rotating column 124 is slidably connected to the inner wall at the port of the second sliding groove 111, and the second rotating column 125 is slidably connected to the inner wall at the port of the third sliding groove 112.

[0034] The fourth slide groove 113 has a second mounting groove 114 on its side wall. An adjustment component 13 is provided inside the second mounting groove 114. The adjustment component 13 includes a spring 131 with one end fixedly connected to the bottom wall of the second mounting groove 114. A push block 132 is fixedly connected to one end of the spring 131. The spring 131 is used to push the push block 132 to drive the drive column 122 into the second drive groove 251 when the display needs to be reset to below the button. This allows the display to be reset through the protective component 2, increasing the smoothness of the display reset.

[0035] The lower end of the controller body 1 is provided with a placement groove 102. A locking block 103 is fixedly connected to the top wall of the placement groove 102. A locking groove 222 is provided on the side wall of the first moving frame 22. The locking block 103 and the locking groove 222 are engaged and connected. The engagement of the locking block 103 and the locking groove 222 is used to limit the movement between the protective component 2 and the controller body 1 after the support is formed.

[0036] A limiting block 26 is fixedly connected to the side wall of the first connecting plate 231. The limiting block 26 is slidably connected to the inner wall of the third mounting groove 23. The limiting block 26 is used to limit the first connecting plate 231 and prevent one end of the first connecting plate 231 from directly detaching from the third mounting groove 23.

[0037] One end of the second slide rail 111, the third slide rail 112, and the fourth slide rail 113 are all arc-shaped, which are used to guide the display screen from below the buttons to the port of the first mounting slot 11.

[0038] As can be seen from the above, the drive columns 122 on the non-adjacent side walls of the mounting frame 121 of the moving component 12 are slidably connected to the inner wall at the port of the third slide groove 112. The rollers 126 at one end of the first rotating column 124 and the second rotating column 125 are slidably connected to the inner walls of the second slide groove 111 and the third slide groove 112, respectively. When the first moving frame 22 and the second moving frame 25 slide on the inner wall of the first slide groove 101, the drive column 122 is driven by the second drive groove 251, so that the mounting frame 121 moves the display screen from below the button to the port of the first mounting groove 11. At the same time, the protection component 2 removes the protection of the display screen and the button. One end of the spring 131 of the adjusting component 13 is fixed to the inner bottom wall of the second mounting groove 114, and the other end is connected to the push block 132. When it is necessary to reset the display screen to below the button, after pushing the protection component 2 a certain distance in the opposite direction, the spring 131 pushes the push block 132 to drive the drive column 122 into the interior of the second drive groove 251, and then the display screen is reset by the protection component 2, which increases the smoothness of the display screen reset.
