Description

Technical Field

[0001] This utility model relates to the field of support platform technology, specifically a rotating support platform that can increase the support area. Background Technology

[0002] In industrial production, equipment display, or medical assistance scenarios, support platforms are often used to support workpieces, equipment, or items. Their core function is to provide a stable and flat support surface to ensure the positional accuracy or stress stability of objects during operation.

[0003] A search revealed that the announcement number is CN222285126U, and the name is "A Rotary Support Platform, including a fixed plate." Through research and analysis, it was found that although the present invention solves the problem that existing support platforms are supported by support legs, and when operators need to adjust the position of the support platform, the entire platform needs to be moved, which is time-consuming and laborious, resulting in certain limitations in the use of existing devices, the following defects still exist to a certain extent.

[0004] For example, the bearing surface of the above-mentioned support platform is a one-piece structure with an area that cannot be adjusted. When it is necessary to support larger items, a larger platform needs to be replaced, resulting in poor versatility. If it is used to support smaller items, it will waste platform space and cause insufficient stability. Moreover, it is inconvenient to adjust the height of the support platform. This cannot meet different bearing height requirements and has poor practicality. In order to solve the above technical problems, we have designed a rotating support platform that can increase the support area. Utility Model Content

[0005] The purpose of this utility model is to provide a rotating support platform that can increase the support area. It has the advantages of flexible and adjustable support area, adaptability to different sized load-bearing items, strong versatility, and ability to meet different load-bearing heights, thus improving practicality. It solves the problems of fixed support area design that cannot be adjusted, inability to adapt to different load-bearing items, poor versatility, inability to adjust load-bearing height, and poor practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotating support platform that can increase the support area, comprising a base plate, a box welded to the top of the base plate, a drive bevel gear rod installed through bearings on the left and right sides of the inner cavity of the box, a driven bevel gear rod installed through bearings on the top of the inner cavity of the box, a support frame installed on the top of the driven bevel gear rod, a lifting screw installed through bearings on the bottom of the inner cavity of the support frame, a threaded sleeve threaded onto the top of the lifting screw, a fixed frame installed through the top of the threaded sleeve, a sliding column fixedly connected to the inner cavity of the fixed frame, a mounting plate slidably fitted onto the surface of the sliding column, limit sliders and positioning mechanisms respectively installed on the left and right sides and front and rear sides of the mounting plate, push plates movably installed on the top of the limit sliders and positioning mechanisms, a fixed plate welded to the top of the fixed frame, and extension plates hinged around the perimeter of the fixed plate.

[0007] Preferably, the positioning mechanism includes a housing, an inner cavity of which is fitted with a positioning spring, and positioning pins are fixedly connected to both the left and right sides of the positioning spring, with the outer side of the positioning pin extending through to the outer side of the housing.

[0008] Preferably, through openings are provided on both the left and right sides of the outer side of the inner cavity of the housing, and a push block is fixedly connected to the side of the positioning pin near the through opening.

[0009] Preferably, a right rotating wheel is fixedly connected to the right side of the active bevel gear rod, a push rod is slidably mounted through the top right side of the right rotating wheel, and a positioning plate is fixedly connected to the left side of the push rod.

[0010] Preferably, a positioning ring is fixedly connected to the right side of the housing, and a positioning slot is provided on the right side of the positioning ring.

[0011] Preferably, a lower rotating wheel is fixedly connected to the bottom of the lifting screw, guide sliders are welded to the bottom of the threaded sleeve, and guide openings are provided around the inner cavity of the support frame.

[0012] Preferably, the top and bottom of the inner cavity of the front and rear openings of the fixing frame are provided with positioning slots, and the top of the limiting slider and the positioning mechanism are fixedly connected with movable sleeve rods, the surface of which is fixedly connected to the push plate.

[0013] Preferably, the top of the push plate is connected to the extension plate via a movable shaft, and double-brake casters are bolted to the four corners of the bottom of the base plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Push the positioning pin inward to move it out of the positioning slot below, push the limiting slider and the housing upward, and push the extension plate to unfold and become flush with the fixed plate by the upward movement of the push plate. The positioning pins on both sides then insert into the positioning slot above to position the mounting plate. This increases the support area, allowing it to support larger objects or hold more items, making it more versatile.

[0015] The forward or reverse rotation of the lifting screw drives the threaded sleeve to move up and down, and the height of the fixed plate rises or falls accordingly. This allows for flexible adjustment of the load-bearing height of the device, improving its practicality.

[0016] Rotating the right-hand wheel drives the active bevel gear rod to rotate, which in turn drives the support frame to rotate via the driven bevel gear rod. The upper support platform then rotates accordingly, enabling the support device to have a rotational function. Attached Figure Description

[0019] Please see Figures 1-5A rotating support platform with an increased support area includes a base plate 1. A housing 2 is welded to the top of the base plate 1. A drive bevel gear rod 21 is installed through bearings on the left and right sides of the inner cavity of the housing 2. Gears on the drive bevel gear rod 21 and the driven bevel gear rod 20 mesh with each other. A driven bevel gear rod 20 is installed through bearings on the top of the inner cavity of the housing 2. A support frame 12 is installed on the top of the driven bevel gear rod 20. A lifting screw rod 7 is installed through bearings on the bottom of the inner cavity of the support frame 12. A threaded sleeve 8 is threaded onto the top of the lifting screw rod 7. The top of the threaded sleeve 8 passes through the support frame 12 and is fitted with a fixing frame 9. The inner cavity of the fixing frame 9 is fixedly connected to a sliding column 18. By setting the sliding column 18, the mounting slide 24 can slide up and down on its surface. The mounting slide 24 is slidably fitted on the surface of the sliding column 18. Limiting sliders 19 and positioning mechanisms 16 are respectively installed on the left and right sides and the front and rear sides of the mounting slide 24. Push plates 23 are movably installed on the top of both the limiting sliders 19 and the positioning mechanisms 16. A fixing plate 10 is welded to the top of the fixing frame 9. Extension plates 11 are hinged around the fixing plate 10. Please see Figure 4 The positioning mechanism 16 includes a housing 27, and a positioning spring 28 is installed in the inner cavity of the housing 27. By setting the positioning spring 28, the positioning pin 25 can be elastically supported. By releasing the elastic force, the positioning pin 25 is pushed into the positioning slot 22. Positioning pins 25 are fixedly connected to both sides of the positioning spring 28, and the outer side of the positioning pin 25 extends through to the outer side of the housing 27. Please see Figure 4 Through openings are provided on both the left and right sides of the inner cavity of the housing 27. A push block 26 is fixedly connected to the side of the positioning pin 25 near the through opening. By setting the push block 26, it is easier to push the positioning pin 25. Please see Figure 2 and Figure 5 A right rotating wheel 4 is fixedly connected to the right side of the active bevel gear rod 21. By rotating the right rotating wheel 4, the active bevel gear rod 21 can be driven to rotate, and then the driven bevel gear rod 20 drives the support frame 12 to rotate, enabling the support device to have a rotation function. A push rod 15 is slidably installed through the top of the right side of the right rotating wheel 4. A positioning plate 29 is fixedly connected to the left side of the push rod 15. When the right rotating wheel 4 is rotated, the push rod 15 is pulled outward to move the positioning plate 29 out of the positioning slot 30. When it is rotated to the appropriate position, the push rod 15 is pushed to insert the positioning plate 29 into the corresponding positioning slot 30. This can position the right rotating wheel 4 to prevent it from rotating randomly. Please see Figure 5 A positioning ring 3 is fixedly connected to the right side of the housing 2. A positioning slot 30 is provided on the right side of the positioning ring 3. There are several positioning slots 30, which are arranged at equal angles. Please see Figure 2The bottom of the lifting screw 7 is fixedly connected to a lower rotating wheel 6. By setting the lower rotating wheel 6, the lifting screw 7 can be rotated easily. The bottom of the threaded sleeve 8 is welded with guide sliders 13. The inner cavity of the support frame 12 is provided with guide openings 14. By setting the guide openings 14, the guide sliders 13 can move up and down inside to guide and limit the threaded sleeve 8, preventing it from rotating with the lifting screw 7. Please see Figure 2 and Figure 3 The top and bottom of the openings on the front and rear sides of the fixed frame 9 are provided with positioning slots 22. The top of the limiting slider 19 and the positioning mechanism 16 are fixedly connected with movable sleeve rods 17. By setting the movable sleeve rods 17, the bottom of the push plate 23 can be movably installed. The surface of the movable sleeve rods 17 is fixedly connected to the push plate 23. Please see Figure 1 and Figure 3 The top of the push plate 23 is connected to the extension plate 11 via a movable shaft. The four corners of the bottom of the base plate 1 are all equipped with double brake casters 5 by bolts. By setting the double brake casters 5, the device can be moved easily and can be stopped at the same time.

[0020] In use, push the device to a suitable bearing position. When a larger item needs to be supported, push the positioning pins 25 on both sides inward to move them out of the positioning slots 22 below. Then push the limiting slider 19 and the housing 27 upward. The bottom of the surrounding push plates 23 moves upward, pushing the surrounding extension plates 11 to unfold and become flush with the fixed plate 10. At this time, the positioning pins 25 on both sides are inserted into the positioning slots 22 on both sides above to position the mounting plate 24. This increases the support area, allowing it to support larger objects or hold more items, making it more versatile. When the bearing height of the item needs to be adjusted, rotate the lifting screw 7 in the forward or reverse direction to move the threaded sleeve 8 up and down. The height of the fixed plate 10 will rise or fall accordingly, thus flexibly adjusting the bearing height of the device and improving its practicality.

[0021] In summary, this rotating support platform, which can increase the support area, solves the problems of fixed support area design, inability to adapt to different load-bearing items, poor versatility, inability to adjust load-bearing height, and poor practicality through the coordinated use of base plate 1, lower rotating wheel 6, lifting screw 7, threaded sleeve 8, fixing frame 9, fixing plate 10, extension plate 11, support frame 12, positioning mechanism 16, sliding column 18 and push plate 23.
