[0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to computers, VCDs, DVDs, BDs, game consoles, DVs, etc. through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools, and entertainment venues. Depending on the working method, there are different types such as CRT, LCD, DLP, 3LCD, etc. When using a projector, in order to determine the projection position, a projector stand is required to assist.

[0003] Projector stands are roughly divided into three types: floor-standing, wall-mounted and ceiling-mounted. The installation methods of wall-mounted and ceiling-mounted are relatively similar, and you can choose a suitable projector stand according to the actual environment on site.

[0004] Most of the projector brackets in the prior art have only one installation mode, which makes it impossible to adjust the installation mode according to the actual installation requirements on site, and has poor practicality.

A connecting block is fixedly connected to the right end of the mounting rod, and the connecting block is movably connected to the left end of the movable rod through a pin shaft.

[0008] In a further technical solution, a semicircular ring is fixedly connected to the top of the movable rod, the inclined rod is movably connected to the inner side of the semicircular ring, and a hanging ring is fixedly connected to the top of the inclined rod.

[0009] In a further technical solution, a fixing ring is fixedly connected to the outer side of the mounting rod, a spring is fixedly connected to the right side of the fixing ring, and the spring is fixedly connected to the left side of the sleeve.

[0010] In a further technical solution, a transmission rod is fixedly connected to the bottom of the shell, and the bottom end of the transmission rod passes through the movable rod and is movably connected to the movable rod through a bearing.

[0011] In a further technical solution, a movable groove is provided on the top of the shell, the top of the clamping block passes through the movable groove and extends outside the shell, and anti-slip pads are fixedly connected to the opposite surfaces of the two clamping blocks.

[0023] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0024] Example:

[0025] like Figure 1-Figure 5 As shown, an adjustable projector bracket includes a mounting base 1, a U-shaped base 2 is fixedly connected to the right side of the mounting base 1, a mounting rod 5 is movably connected to the inner side of the U-shaped base 2 through a pin shaft, a movable rod 7 is arranged at the right end of the mounting rod 5, a sleeve 6 is sleeved on the outer side of the mounting rod 5, an inclined rod 9 is arranged above the movable rod 7, a hook 3 is fixedly connected to the top of the mounting rod 5, a shell 8 is arranged on the top of the movable rod 7, a bidirectional threaded rod 20 is threadedly connected to the inner side of the shell 8, and a clamping block 13 is threadedly connected to the outer side of the bidirectional threaded rod 20.

[0026] The working principle of the above technical solution is as follows:

[0027] Select a suitable installation method for the projector according to the actual situation on site. When it needs to be adjusted to a ceiling-mounted installation, pull the sleeve 6 to the left until the limit on the movable rod 7 is cancelled. At this time, flip the movable rod 7 until the hanging ring 10 can be hooked into the hook 3. At this time, the movable rod 7 and the installation rod 5 are in a vertical state, and the projector can be placed on the top of the shell 8, and the projector is fixed and limited under the action of the clamp 13.

[0028] In another embodiment, if Figure 1 As shown, a rubber ring 4 is fixedly connected to the outside of the mounting rod 5, and the outside of the rubber ring 4 is tightly fitted with the inside of the U-shaped seat 2. A connecting block 14 is fixedly connected to the right end of the mounting rod 5, and the connecting block 14 is movably connected to the left end of the movable rod 7 through a pin shaft.

[0029] The position of the mounting rod 5 is limited under the action of the rubber ring 4 to ensure that the mounting rod 5 can be placed stably after the position is adjusted and is not easily moved under the action of external force. The movable rod 7 can be turned over under the action of the connecting block 14.

[0030] In another embodiment, if Figure 3 As shown, a semicircular ring 15 is fixedly connected to the top of the movable rod 7, the inclined rod 9 is movably connected to the inner side of the semicircular ring 15, and a hanging ring 10 is fixedly connected to the top of the inclined rod 9.

[0031] Under the action of the semicircular ring 15, the bottom end of the inclined rod 9 can be limited to ensure that it can slide outside the semicircular ring, and under the action of the hanging ring 10, it is convenient to connect with the hook 3.

[0032] In another embodiment, if Figure 2 As shown, a fixing ring 12 is fixedly connected to the outside of the mounting rod 5 , a spring 11 is fixedly connected to the right side of the fixing ring 12 , and the spring 11 is fixedly connected to the left side of the sleeve 6 .

[0033] The position of the spring 11 is limited under the action of the fixing ring 12. When the movable rod 7 and the mounting rod 5 are in a straight line under the action of the spring 11, the sleeve 6 can be located outside the movable rod 7 and the mounting rod 5 to limit the position of the movable rod 7.

[0034] In another embodiment, if Figure 3 As shown, a transmission rod 16 is fixedly connected to the bottom of the housing 8, and the bottom end of the transmission rod 16 passes through the movable rod 7 and is movably connected to the movable rod 7 through a bearing.

[0035] The housing 8 can be rotated under the action of the transmission rod 16, and the position of the housing 8 can be adjusted to select a suitable projection direction of the projector.

[0036] In another embodiment, if Figure 4 As shown, a movable groove 17 is opened on the top of the shell 8, and the top of the clamping block 13 passes through the movable groove 17 and extends to the outside of the shell 8. The opposite surfaces of the two clamping blocks 13 are fixedly connected with anti-slip pads.

[0037] The movable groove 17 facilitates the movement of the clamping block 13 , and the anti-skid pad can play an anti-skid role when fixing the projector and protect the outer side of the projector.

[0038] In another embodiment, if Figure 4 As shown, a slide groove 19 is opened at the bottom of the shell 8, a slider 18 is fixedly connected to the bottom of the clamping block 13, the slider 18 is slidably connected to the inner side of the slide groove 19, the right end of the bidirectional threaded rod 20 passes through the right side of the shell 8, and the left and right ends of the outer side of the bidirectional threaded rod 20 are set as reverse threads.

[0039] Under the action of the slider 18 and the slide groove 19, the moving trajectory of the clamp 13 is limited to ensure that it can only move in the left and right directions. The bidirectional threaded rod 20 with reverse threads can rotate the two clamps 13 to move in opposite directions to clamp or release the projector.

[0040] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
