[0017] Example 1

[0018] This embodiment describes a device for industrial display projection, such as... Figure 1 and Figure 2 As shown, it includes a housing 1, a fixing block 10 is vertically fixed on the top of the housing 1, and a top plate 9 is fixed on the top of the fixing block 10. The housing 1 is designed to facilitate the installation and protection of the drive components and to increase stability. The fixing block 10 is designed to facilitate the fixing of the top plate 9 and the installation of the lead screw 4, thereby improving the stability of the placement slot 6 when it is raised or lowered.

[0019] A lead screw 4 that can rotate freely left and right is vertically installed between the top plate 9 and the box body 1. The lead screw 4 is installed to facilitate the lifting and lowering of the placement slot 6, thereby adjusting the projection height of the projector 8.

[0020] The top surface of each housing 1 is provided with a first through hole for the lead screw 4 to pass through. The housing 1 is provided with a drive assembly for driving the lead screw 4 to rotate. The drive assembly facilitates the rotation of the lead screw 4, thereby driving the placement slot 6 to complete the lifting and lowering.

[0021] The drive components are multiple, and each drive component drives only one lead screw 4 to rotate, thereby driving the placement slot 6 on the lead screw 4 to rise and fall, which makes it easier to adjust each projector 8 separately and makes it more convenient.

[0022] The lead screw 4 located between the top plate 9 and the box 1 is fitted with a ball nut that is threaded to it. A fixing plate 7 is fixed to the outer wall of the ball nut. The ball nut is designed to allow the fixing plate 7 to drive the placement groove 6 to move vertically up and down, making it more stable during the lifting process.

[0023] The fixed plate 7 is hinged to the upper and lower communicating placement groove 6 by the connecting block, and the placement groove 6 swings left and right along the width direction of the fixed plate 7. The setting of the connecting block makes it easy for the placement groove 6 to swing left and right, thereby making the projection angle of the projector 8 larger and increasing its applicability.

[0024] The structure of the placement slot 6 is as follows: Figure 1 and Figure 2 The shape shown can also be a trough made of three plates, which facilitates the placement of the base plate 12 and the projector 8.

[0025] The placement slot 6 is horizontally provided with a base plate 12 that swings up and down with it. The projector 8 is placed on the top surface of the base plate 12. The swinging of the base plate 12 makes it easy to adjust the tilt angle of the projector 8, thereby increasing its projection angle and making its projection surface more perfect to meet various projection needs.

[0026] The top surface of the base plate 12 is provided with a locking component for fixing the projector 8 to the base plate 12. The locking component is designed to prevent the projector 8 from falling off during use, thereby ensuring the normal use of the projector 8 and increasing its stability.

[0027] The projector 8 is connected to the computer via WiPlug, which is an existing technology. When in use, the computer, mobile phone or tablet is connected to the same WIFI network as the WiPlug, and then the content on the computer, mobile phone or tablet can be displayed synchronously on the projector screen, which avoids the inconvenience of too many cables in installation and affects the use.

[0028] During use, such as Figure 1 and Figure 2 As shown, first place the device in a suitable position, then lower the placement slot 6 to a suitable height by driving the device. Then place the connected projector 8 on the base plate 12 and fix it by locking the device. Then adjust the vertical tilt angle required for projection by using the base plate 12, and then adjust the horizontal offset angle by using the connecting block. After adjustment, drive the screw 4 to rotate by using the drive component, thereby raising the projector 8 to the required projection height.

[0029] Example 2

[0030] This embodiment further illustrates the technology, such as Figure 1 and Figure 2 As shown, a placement groove is provided at the bottom of the top plate 9. Bearings are installed in both the placement groove and the first through hole. The outer ring of the bearing is fixed to the groove wall of the placement groove and the hole wall of the first through hole, respectively, and the inner ring is fixed to the lead screw 4. The placement groove facilitates the installation of the bearing and the top of the lead screw 4. The bearing is designed to improve the smoothness of the rotation of the lead screw 4, thereby making it more convenient and faster to raise and lower the placement groove 6.

[0031] Example 3

[0032] This embodiment further illustrates the technology, such as Figure 1 and Figure 2 As shown, the drive assembly includes a horizontally arranged connecting rod 2. Gears are fitted on both the lead screw 4 and the connecting rod 2 located inside the housing 1, and the two gears are meshed. A hand crank 3 for driving the connecting rod 2 to rotate is installed on the connecting rod 2 located outside the housing 1. The setting of the connecting rod 2 facilitates the rotation of the lead screw 4 through the gears, and the setting of the hand crank 3 facilitates the rotation of the connecting rod 2, thereby driving the projector 8 to rise and fall.

[0033] The drive component can also be a motor. In use, the motor is vertically installed inside the housing 1, and then the output shaft of the motor is connected to the lead screw 4. The motor makes it easier and faster to rotate the lead screw 4, thereby making it easier and faster to raise and lower the projector 8.

[0034] Example 4

[0035] This embodiment further illustrates the technology, such as Figure 1 and Figure 2 As shown, the wall of the fixed block 10 is vertically provided with a first sliding groove, and a first slider is provided in the first sliding groove to slide vertically with it. The first slider is fixed to the adjacent fixed plate 7 respectively. The opening of the first sliding groove and the setting of the first slider make it easier to keep the fixed plate 7 vertically raised and lowered, so that the fixed plate 7 is more stable when it is raised and lowered.

[0036] The first slide is a "T" shaped slide, and the first slider is a "T" shaped slider, which helps to prevent the plate from falling off during the up and down sliding process and affecting the stability of the lifting of the fixed plate 7.

[0037] Example 5

[0038] This embodiment further illustrates the technology, such as Figure 1 and Figure 2 As shown, there are two connecting blocks. One block is horizontally fixed on the fixing plate 7, and the other block is horizontally fixed on the placement groove 6. The two connecting blocks are placed overlapping each other. The overlapping section of the two connecting blocks is provided with a second through hole that is open from top to bottom. A first bolt is inserted into the second through hole. The setting of the connecting blocks and the first bolt makes it easy to adjust the left and right offset angle of the fixing plate 7 by adjusting the tightness of the first bolt, so that the projection angle of the projector 8 is larger.

[0039] Example 6

[0040] This embodiment further illustrates the technology, such as Figure 1 and Figure 2 As shown, the side wall of the placement groove 6 is provided with a third threaded through hole, and a second bolt is installed in the third threaded through hole. The base plate 12 is fixed on the screw of the second bolt located in the placement groove 6. The opening of the third threaded through hole facilitates the installation of the second bolt. The base plate 12 is fixed on the second bolt so that the position of the base plate 12 is also fixed when the second bolt is fixed. When the second bolt is rotated, it drives the base plate 12 to flip up and down, thereby driving the projector 8 to adjust the projection angle up and down.

[0041] Example 7

[0042] This embodiment further illustrates the technology, such as Figure 1 and Figure 2As shown, the locking assembly is a clamping plate 11. The top of the base plate 12 is provided with a second sliding groove for the clamping plate 11 to slide left and right. A second slider is provided in the second sliding groove and slides left and right with it. The second slider is fixed to the bottom of the clamping plate 11. The clamping plate 11 is provided to facilitate the clamping and fixing of the projector 8.
