[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown, the utility model provides a projector for office use in industrial and commercial enterprises, comprising:

[0024] Projector 1;

[0025] The bottom of the projector 1 is fixedly connected with a connection box 2, and the left and right sides of the inner wall of the connection box 2 are slidably connected with a support mechanism 3;

[0026] The supporting mechanism 3 includes a slider 31, a handle 32, a slide column 33, a rectangular plate 34, a slide plate 35, a support leg 36 and a support plate 37. The slider 31 is slidably connected to the left and right sides of the inner wall of the connection box 2, the left side of the slider 31 is fixedly connected to the handle 32, the left side of the handle 32 passes through the left side of the connection box 2, the inner side of the slider 31 is slidably connected to the slide column 33, the center of the inner cavity of the connection box 2 is longitudinally fixedly connected to the rectangular plate 34, the left and right sides of the rectangular plate 34 are slidably connected to the slide plate 35, the bottom of the slide plate 35 is fixedly connected to the support leg 36, and the bottom of the support leg 36 passes through the bottom of the connection box 2 and is fixedly connected to the support plate 37.

[0027] refer to Figure 2 The surface of the slider 31 is provided with an oblique groove 4 , which is used in conjunction with the slide post 33 .

[0028] As a technical optimization solution of the present invention, the oblique groove 4 is provided to enable the slide post 33 to move inside the oblique groove 4 and to play a limiting role, thereby preventing the slide post 33 from being separated during the movement.

[0029] refer to Figure 2 The left and right sides of the top of the slide plate 35 are fixedly connected with telescopic rods 5, and the top of the telescopic rod 5 is fixedly connected to the top of the inner wall of the connection box 2.

[0030] As a technical optimization solution of the present invention, the telescopic rod 5 is provided to assist the slide plate 35 in working, thereby preventing the slide plate 35 from rebounding due to resistance during movement.

[0031] refer to Figure 2 Openings 6 are provided on the left and right sides of the bottom of the connection box 2 and correspond to the positions of the support plate 37 , and the openings 6 are used in conjunction with the support plate 37 .

[0032] As a technical optimization solution of the utility model, the setting of the opening 6 can enable the support plate 37 to completely pass through the opening 6 for mechanical transmission, thereby avoiding the phenomenon that the support plate 37 is stuck at the opening 6 due to the width of the opening 6 being too narrow.

[0033] refer to Figure 2 A slide groove 7 is provided on the surface of the rectangular plate 34 and corresponds to the position of the slide plate 35 , and the slide groove 7 is used in conjunction with the slide plate 35 .

[0034] As a technical optimization solution of the present invention, the slide plate 35 can move up and down in the slide plate 7 by setting the slide groove 7, and at the same time play a role of limiting, thereby avoiding the phenomenon of displacement of the slide plate 35 during the movement.

[0035] refer to Figure 3 The bottom of the support plate 37 is fixedly connected with a rubber pad 8 , and the rubber pad 8 is used in conjunction with the support plate 37 .

[0036] As a technical optimization solution of the present invention, the rubber pad 8 can assist the support plate 37 in its work and play a protective role, thereby avoiding the phenomenon of scratches and damage caused by direct contact between the support plate 37 and the desktop.

[0037] The working principle and use process of the utility model are as follows: when in use, the projector 1 is placed on the desktop, and then the handle 32 is manually pushed forward. The handle 32 moves forward and drives the slider 31 to move with it. The slider 31 moves forward and cooperates with the oblique groove 4 to force the slide post 33 to move downward. The slide post 33 moves downward and drives the slide plate 35 to move with it. The slide plate 35 cooperates with the slide groove 7 to move inside the rectangular plate 34. The movement of the slide plate 35 stretches the telescopic rod 5 and does work. Finally, the slide plate 35 drives the supporting legs 36 and the supporting plate 37 to extend out of the opening 6. The supporting plate 37 contacts the desktop to raise the projector 1 as a whole to keep it balanced and stable.

[0038] In summary: the industrial and commercial office projector, through the coordinated use of the projector 1, the connection box 2, the support mechanism 3, the slider 31, the handle 32, the slide column 33, the rectangular plate 34, the slide plate 35, the support leg 36 and the support plate 37, solves the problem that the existing projector cannot maintain balance and stability on an uneven desktop during use.
