Description

Technical Field

[0001] The utility model relates to the technical field of projection brackets, in particular to a classroom projection fixing bracket. Background Art

[0002] Projection refers to the process of projecting the shape of an object onto a plane using a set of light rays. The resulting image on that plane is also called a projection. Projections can be categorized as orthographic and oblique. Orthographic projections are those in which the centerline of the projection line is perpendicular to the projection plane. Oblique projections are those in which the centerline is not perpendicular to the projection plane. A multimedia classroom projector is a device that projects images or videos onto a screen. It typically utilizes advanced display technologies, such as liquid crystal display (LCD) or digital light processing (DLP), to provide high-definition projection images. Multimedia classroom projectors can connect to computers, video display stands, VCD players, DVD players, VCRs, and other devices to transmit video and computer signals to the screen, enabling multimedia teaching applications. Projectors are a core component of presentation and display in multimedia classrooms, providing students and teachers with high-quality visual presentations, enhancing student interest and motivation, and improving the quality and effectiveness of teaching.

[0003] When existing projectors are used as teaching tools in classrooms, they are mostly hung on the ceiling of the classroom for fixing instead of fixing on the desktop to prevent the projectors from being damaged by the complicated crowd in the classroom. However, this fixing method makes it inconvenient to repair and replace the projectors when they are damaged, especially the fixing bracket. Therefore, we propose a new projector fixing bracket.

[0028] In the related art, when projectors are used as teaching tools in classrooms, they are mostly hung on the ceiling of the classroom for fixing, rather than fixed on the table, to prevent the projectors from being damaged by the crowds in the classroom. However, this fixing method makes it inconvenient to repair and replace the projectors when damaged, especially the fixing bracket.

[0029] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a classroom projection mounting bracket. When it needs to be used, the mounting bracket only needs to be set into two parts. One part is fixed to the wall and is set directly and immovably, and the other part is fixed to the projector 12 and is set in a detachable style.

[0030] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0031] Combine Figure 1-Figure 3 The embodiment of the present application provides a classroom projection mounting bracket, including a projection device 1; the projection device 1 includes: a projector 12 is arranged at the bottom of a support column 11; a slide 13 is arranged at the top of the support column 11; a fixed seat 14 is arranged at the top of the support column 11, accommodating the slide 13; a slide groove 15 is opened at the top of the fixed seat 14; a stopper 16 is arranged inside the slide groove 15; a card slot 17 is opened at the bottom of the slide groove 15; and a fixing bolt 18 passes through the fixed seat 14.

[0032] When in use, the fixing seat 14 is installed on the top of the classroom through the fixing bolt 18, the bottom of the support column 11 is fixed to the projector 12 by bolts, and the top is clamped in the slide groove 15 of the fixing seat 14 through the slide 13, and then the block 16 is placed in the slot 17 to block the sliding path of the slide 13 in the slot 15. The slide 13 is now in the slot 15, thereby fixing the support column 11 and the slide 13. When the projector 12 and the support column 11 need to be removed, the block 16 is removed from the slot 17, and the slide 13 and the support column 11 can be slid out.

[0033] Specifically, the model of the projector 12 is A4300.6, which belongs to the prior art and is not shown in detail in the accompanying drawings.

[0034] In some embodiments, a magnetic block 161 is provided at the bottom of the stopper 16. The magnetic block 161 is used to facilitate the stopper 16 to be adsorbed and fixed in the slot 17.

[0035] In some embodiments, the projection device 1 is provided with an auxiliary component 2, which includes a limiting rod 21 disposed on the outer wall of the fixing seat 14 and extending through the fixing seat 14; and a spring 22 sleeved on the outer wall of the limiting rod 21, with both ends connecting the fixing seat 14 and the limiting rod 21. The limiting rod 21 further limits and secures the slide 13. To remove the slide 13, the limiting rod 21 is pulled outward to move it out of the slide slot 15, which stretches the spring 22. When the limiting rod 21 is released, the spring 22 drives the limiting rod 21 back into place.

[0036] In some embodiments, both ends of the stopper 16 are provided with fixing holes 23 that cooperate with the limiting rod 21. The limiting rod 21 is inserted into the fixing holes 23 in the stopper 16, and the two limiting mechanisms cooperate with each other to increase stability.

[0037] In some embodiments, a fixing ring 24 is sleeved on the outer side of the fixing bolt 18, and a protective cover 25 is provided on the outer side of the fixing ring 24 to cooperate with the limiting rod 21. The protective cover 25 is fixed to the fixing bolt 18 through the fixing ring 24 to shield and protect the limiting rod 21. When the limiting rod 21 needs to be pulled, the protective cover 25 is directly opened.

[0038] In some embodiments, a ring body 26 is sleeved on the outer side wall of the fixing bolt 18, and the fixing ring 24 is rotatably connected to the fixing bolt 18 via the ring body 26. The fixing ring 24 is sleeved on the fixing bolt 18 via the ring body 26 and rotates, thereby preventing the fixing ring 24 from being unable to rotate due to the tightening of the fixing bolt 18. At the same time, there is a certain frictional resistance between the fixing ring 24 and the ring body 26.

[0039] In some embodiments, a baffle 141 is provided on one side of the fixing seat 14. The baffle 141 is used to prevent the sliding seat 13 from sliding down from the rear.

[0040] In some embodiments, the height of the slide 13 is equal to the height of the slide groove 15. The slide 13 and the slide groove 15 are equal in height, which can prevent the slide 13 and the support column 11 from shaking.
