Abstract
Description
Technical Field
[0001] This application relates to the technical field of raised floors, and particularly relates to a load-bearing support base for raised floors. Background Art
[0002] A load-bearing support base for raised floors is a structural element used to support raised floors, mainly for constructing an adjustable-height platform above the ground. These bases are usually made of durable materials such as metal or heavy-duty plastic to ensure structural stability and load-bearing capacity. Raised floor systems are commonly used in office buildings, data centers, or other places where space is required below the floor for wiring, ventilation, or hiding equipment.
[0003] Currently, among the used raised floor support bases, the design of the load-bearing support base can be of fixed height or adjustable height, depending on actual requirements and floor design. The height-adjustable bases generally use a threaded connection method for adjustment. However, in the way of relying solely on the threaded support after adjustment, the support strength cannot be guaranteed, and metal fatigue may occur after long-term use, resulting in the phenomenon of thread slipping. And using the method of directly fixing with screws is not conducive to subsequent adjustment and use. Therefore, a load-bearing support base for raised floors is designed to solve the above-mentioned problems. Summary of the Utility Model

An adjustment tube is threadedly connected to the upper end of the threaded rod. Limiting frames are fixedly connected to both sides of the adjustment tube. A fixing groove is formed in the limiting frame. A limiting block is slidably connected to one side of the fixing groove. The limiting block is inserted into a support rod.
[0007] Preferably, a support fixing plate is fixedly connected to the upper end of the adjustment tube, and an installation groove is formed in the fixing plate.
[0008] Preferably, a plurality of slots are formed in one side of the support rod close to the same-side limiting block, and the limiting block is inserted into the slots.
[0009] Preferably, a connecting rod is fixedly connected to one side of the limiting block away from the support rod. The side of the connecting rod away from the limiting block passes through the side wall of the limiting frame and is rotatably connected to a pull handle.
[0010] Preferably, an elastic sheet is fixedly connected to one side of the limiting block close to the connecting rod, and one side of the elastic sheet is fixedly connected to the inner wall of the fixing groove.

[0012] Preferably, a rotating ring is fixedly connected to the threaded rod, and the lower end of the rotating ring is rotatably connected to the support plate.
[0013] In summary, the present application includes the following beneficial technical effects:
[0014] In the present utility model, by providing the limiting frame and the support rod structures installed on both sides of the adjusting pipe, after the threaded rod drives the adjusting pipe to lift and lower to adjust the height of the fixing plate, the elastic piece drives the connecting rod, so that the limiting block enters the slot of the support rod to be fixed, thereby connecting the support rod and the limiting frame, making the adjusting pipe on one side of the limiting frame fixed, playing a role in assisting in supporting the adjusting pipe, and preventing the situation of metal fatigue and thread slipping due to thread load-bearing.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following will further describe the present application in detail Figures 1-3 with reference to the attached drawings.
[0020] The embodiment of the present application discloses an elevated floor load-bearing support base. Referring to Figures 1-3 , an elevated floor load-bearing support base includes a support plate 1, the upper end of the support plate 1 is rotatably connected to a threaded rod 3, the upper end of the threaded rod 3 is threadedly connected to an adjusting pipe 4, the upper end of the adjusting pipe 4 is fixedly connected to a support fixing plate 5, and a mounting groove is opened on the fixing plate 5 for connecting with the elevated floor. Limiting frames 6 are fixedly connected to both sides of the adjusting pipe 4, a fixing groove 61 is opened in the limiting frame 6, a limiting block 7 is slidably connected to one side of the fixing groove 61, the limiting block 7 is inserted into the support rod 12, and by inserting the limiting block 7 into the support rod 12, the support rod 12 is connected and fixed to the limiting frame 6, so that the adjusting pipe 4 connected to the limiting frame 6 is fixed, playing a role in assisting in supporting the adjusting pipe 4;
[0021] A number of slots 13 are provided on the side of the support rod 12 close to the same-side limit block 7. The limit block 7 is inserted into the slots 13. Setting multiple groups of slots 13 can facilitate the connection with the limit frame 6 and the limit block 7 driven by the adjusting pipe 4, so that the limit block 7 can enter different slots 13 after adjustment, thereby fixing the adjusting pipe 4.
[0022] By adopting the above technical solution, a connecting rod 71 is fixedly connected to the side of the limit block 7 away from the support rod 12. The side of the connecting rod 71 away from the limit block 7 passes through the side wall of the limit frame 6 and is rotatably connected to a pull handle 8. The provided pull handle 8 can drive the connecting rod 71 to move, so that the connecting rod 71 drives the limit block 7 to move, and the limit block 7 enters and exits the slots 13.
[0023] An elastic sheet 9 is fixedly connected to the side of the limit block 7 close to the connecting rod 71. One side of the elastic sheet 9 is fixedly connected to the inner wall of the fixed slot 61. The provided elastic sheet 9 can drive the limit block 7 to move, so that the limit block 7 can enter the slots 13, and the limit frame 6 and the support rod 12 are fixedly connected.
[0024] By adopting the above technical solution, mounting plates 10 are fixedly connected to the upper and lower ends of the pull handle 8, and a stop rod 11 is fixedly connected to one side of the mounting plate 10. The provided stop rod 11 can, when the limit block 7 needs to be fixed, use the stop rod 11 to contact the side wall of the limit frame 6 to prevent the elastic sheet 9 from pushing the limit block 7, thereby facilitating the use of the limit block 7.
[0025] By adopting the above technical solution, a rotating ring 2 is fixedly connected to the threaded rod 3. The lower end of the rotating ring 2 is rotatably connected to a support plate 1. The provided rotating ring 2 can facilitate driving the threaded rod 3 to rotate, so that the threaded rod 3 rotates to drive the adjusting pipe 4 to rise and fall.
[0026] The implementation principle of an elevated floor load-bearing support base in an embodiment of this application is as follows: Fix the support plate 1 to the ground with screws. Then, according to the required height of the elevated floor, first pull the handles 8 on both sides, so that the handles 8 drive the connecting rod 71 to move. The connecting rod 71 drives the limit block 7 on one side to move, causing the limit block 7 to leak out of the inserted slot 13 and separate from the slot 13. At the same time, the limit block 7 will move and squeeze the elastic piece 9 to contract. At this time, rotate the handle 8, so that the handle 8 drives the mounting plate 10 to rotate. The mounting plate 10 drives the stop rod 11 to rotate, so that the end face of the stop rod 11 faces the limit frame 6 after rotation. At this time, release the handle 8, and the elastic piece 9 will push the limit block 7 to move, and the stop rod 11 on one side of the handle 8 will also abut against the side wall of the limit frame 6, making it impossible for the elastic piece 9 to drive the limit block 7 to move. At this time, the rotating ring 2 can be rotated, and the adjusting pipe 4 can be held by hand, so that the rotating ring 2 drives the threaded rod 3 to rotate and drives the adjusting pipe 4 to adjust the height, and drives the fixing plate 5 to be adjusted. After adjustment, the handle 8 can be rotated again, so that the handle 8 drives the mounting plate 10 to rotate. The mounting plate 10 drives the stop rod 11 to rotate and return to its original position, so that the end face of the stop rod 11 no longer contacts the side of the limit frame 6. At this time, the elastic piece 9 will drive the limit block 7 to return to its original position, and the limit block 7 will be clamped into the slot 13 again, so that the support rod 12 and the limit frame 6 are connected, so that the support rod 12 fixes the limit frame 6 and fixes the adjusting pipe 4, playing a role in assisting in supporting the adjusting pipe 4.
