Embodiment 2

[0034] Such as Figure 4As shown, the difference with Embodiment 1 is that: the base 10 is also provided with a sliding seat 70 and a seat 90 installed on the sliding seat 70, and the sliding seat 70 is horizontally slidably connected with the base 10; The spring 80 is connected on the sliding seat 70 . Seat 90 is connected by gas spring 80, then the height of seat 90 can be adjusted easily, thereby adapts to the use of people of different heights.

[0035] After step 2, the following steps are also included: the user adjusts the position of the sliding seat 70, and adjusts the height of the seat 90 through the gas spring 80, and then sits on the seat 90 to adjust the height of the projection device. The user can sit on the seat 90 to adjust the height of the projection device, and the sliding seat 70 is convenient for adjusting the position of the seat 90 to suit different users; at the same time, the user can also sit on the seat when performing a projection demonstration. ...

Embodiment 3

[0037] Such as Figure 5 As shown, the difference from Embodiment 2 is that: the second supporting platform 50 is provided with a positioning groove 51 for the projection device; the opposite side walls of the positioning groove 51 are provided with a positioning structure, and the positioning structure includes a sliding hole 52 , elastic piece 53, push rod 54 and collet 54, one end of push rod 54 is slidably connected in sliding hole 52 through elastic piece 53, and the other end is connected with collet 54, used elastic piece 53 is stage clip in the present embodiment.

[0038] Step 2 also includes the following steps: first push the ejector rod 54 to make the ejector rod 54 squeeze the compression spring, then put the projection device into the positioning groove 51, then release the ejector rod 54, the compression spring resets, and the clamp at one end of the ejector rod 54 The head 54 can hold the projection device in place. This can ensure the stability of the project...

Abstract

The application of the patent discloses a use method of a bracket for projection equipment. The use method comprises the following use steps: (1) when the bracket is not used, respectively arranging a first inner sleeve and a second inner sleeve in a first outer sleeve and a second outer sleeve in an internally sleeving manner; (2) when the bracket is used, placing a notebook computer on a second support table, and placing projection equipment on a first support table; (3) starting the projection equipment, then repeatedly extruding and loosening an air bag body, and inflating the first outer sleeve and the second outer sleeve; (4), increasing the pressure of air in the first outer sleeve and the second outer sleeve, thereby pushing pistons at the lower ends of the first inner sleeve and the second inner sleeve to move upwards; and (5), after the bracket is used, opening an air releasing valve on the air bag body, and releasing air out of the first outer sleeve and the second outer sleeve through the air releasing valve, thereby respectively retracting the first inner sleeve and the second inner sleeve into the first outer sleeve and the second outer sleeve. When the bracket is used, the height of the projection equipment is convenient to regulate, and height fine tuning can be realized.
