DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0023] Figures 1 to 5 It is the best embodiment of the utility model, and the following Figures 1 to 5 The utility model is further described.

[0024] An assembled building support seat comprises a fixed base box 1, a plurality of fixed cones are fixedly arranged at the bottom of the fixed base box 1, and a lifting and fixing mechanism is arranged on the fixed base box 1;

[0025] The lifting and fixing mechanism includes two screw rods 6 rotatably installed on the inner wall of the bottom of the fixed base box 1, and U-shaped blocks 8 are threadedly sleeved on the two screw rods 6. Two guide rods are installed on the inner wall of the bottom of the fixed base box 1. Guide holes are provided at the bottom of the two U-shaped blocks 8, and the two guide rods respectively penetrate the two guide holes. A driving auxiliary support component that allows the two screw rods 6 to rotate simultaneously is provided on the fixed base box 1. A placing table 9 is jointly installed on the top of the two U-shaped blocks 8, and two clamping plates 15 are provided above the placing table 9. An extrusion component that allows the two clamping plates 15 to approach each other is provided on the placing table 9. Multiple placing grooves are provided on the sides of the two clamping plates 15, and clamping blocks 22 are slidably provided in the multiple placing grooves. Elastic components that are compatible with the clamping blocks 22 are provided on the two clamping plates 15.

[0026] In this solution, by arranging the screw rod 6, the U-shaped block 8, the clamping plate 15 and the clamping block 22, it is convenient to adjust the support height of the object to be supported and fix the object to be supported at the same time.

[0027] Specifically, when in use, the auxiliary support assembly is driven to move the U-shaped block 8 through the screw rod 6, and the movement of the U-shaped block 8 will move the placement table 9, thereby adjusting the support height. At the same time, the two clamping plates 15 will be limited by the extrusion assembly and the elastic assembly, and then the support will be limited again by the clamping block 22 and the placement groove, so that the support is limited and fixed to prevent movement.

[0028] The elastic component includes two moving rods 21 respectively installed on the sides of multiple blocks 22, and the sides of the two clamping plates 15 are provided with multiple moving holes compatible with the moving rods 21. The other ends of the multiple moving rods 21 located on one side are commonly installed with a pulling plate 23, and the sides of the multiple blocks 22 are installed with springs 24, and the other ends of the multiple springs 24 are respectively installed on the inner walls of the sides of the multiple placement grooves.

[0029] In this solution, the movable rod 21, the pull plate 23 and the spring 24 are arranged to facilitate the movement of the clamping block 22.

[0030] Specifically, through the setting of the spring 24, the block 22 can be retracted and avoided. At the same time, when the block 22 is aligned with the placement slot, the block 22 enters the placement slot under the action of the spring 24, thereby limiting the support object. When the limit is released, the pull plate 23 is directly pulled. The force on the pull plate 23 will cause the block 22 to move under the action of the moving rod 21, thereby releasing the limit.

[0031] The extrusion assembly includes four movable holes opened on the top of the placement table 9, and two sliding rods are installed on the relative inner walls of the four movable holes. A slider 14 is slidably sleeved on every two matching sliding rods. Two clamping plates 15 are respectively installed on the top of the two sliders 14 located on one side through fixing bolts. The bottom of the four sliders 14 are rotatably installed with inclined plates 16. Two lifting holes are opened on the top of the placement table 9, and lifting blocks 17 are slidably installed on the two lifting holes. The other ends of the two inclined plates 16 on one side are rotatably installed on the side walls at both ends of one of the lifting blocks 17. An elastic reset unit is provided on the placement table 9, and two circular plates 19 are provided above the placement table 9. The two circular plates 19 are respectively installed in cooperation with the two lifting blocks 17 through adjustment units.

[0032] In this solution, the two clamping plates 15 are easily moved by arranging the slide rod, the slide block 14, the inclined plate 16, the lifting block 17 and the circular plate 19.

[0033] Specifically, when placing the object to be supported, the object to be supported will squeeze the circular plate 19 to move it downward. The downward movement of the circular plate 19 will move the slider 14 through the inclined plate 16 and the lifting block 17, thereby making the two clamping plates 15 approach each other, thereby automatically limiting and fixing the object to be supported when it is placed, without the need for subsequent adjustment, thereby reducing the fixing time.

[0034] The elastic reset unit includes a tension spring 20 installed at the bottom of the placement table 9, and a fixing plate is installed on the sides of the two lifting blocks 17 close to each other, and the other end of the tension spring 20 is installed on the top of the fixing plate.

[0035] In this solution, the lifting block 17 can be easily reset by providing the tension spring 20 and the fixing plate.

[0036] Specifically, when the lifting block 17 is not subjected to force, the tension spring 20 will pull the fixed plate to reset, and the reset of the fixed plate will reset the lifting block 17, thereby facilitating the next use.

[0037] The adjusting unit includes a threaded groove opened at the top of the lifting block 17 , a threaded rod 18 is threadedly installed in the threaded groove, and a circular plate 19 is installed at the top of the threaded rod 18 .

[0038] In this solution, the height of the circular plate 19 can be easily adjusted by setting the threaded rod 18 .

[0039] Specifically, the rotation of the circular plate 19 will cause the threaded rod 18 and the threaded groove to move. The movement of the circular plate 19 will change the distance of the bottom movement of the subsequent lifting block 17, thereby changing the spacing between the two clamping plates 15 after movement, thereby facilitating the limiting and fixing of objects to be supported of various widths.

[0040] The driving auxiliary support assembly includes a movable cavity opened on the fixed base box 1, and a movable rod 2 is rotatably installed on the relative inner wall of the movable cavity. One end of the movable rod 2 extends to the outside of the fixed base box 1 and is installed with a rotating plate 3. Two first bevel gears 5 are sleeved on the movable rod 2. The bottom ends of the two screw rods 6 extend into the movable cavity and are respectively installed with second bevel gears 7. The two first bevel gears 5 are respectively meshed with the two second bevel gears 7. Two threaded guide sleeves 10 are sleeved on the movable rod 2. The two threaded guide sleeves 10 are both sleeved with threaded blocks 11. Two avoidance holes compatible with the threaded blocks 11 are opened on the bottom inner wall of the fixed base box 1. Trapezoidal blocks 12 are installed on the tops of the two threaded blocks 11, and two extrusion blocks 13 compatible with the trapezoidal blocks 12 are installed at the bottom of the placement table 9.

[0041] In this solution, by setting the movable rod 2, the rotating plate 3, the first bevel gear 5, the second bevel gear 7, the threaded guide sleeve 10, the threaded block 11, the trapezoidal block 12, and the extrusion block 13, it is convenient to rotate the two screws 6 and increase the force-bearing area at the bottom of the placement table 9.

[0042] Specifically, the rotation of the rotating plate 3 will cause the two screws 6 to rotate through the movable rod 2, the first bevel gear 5 and the second bevel gear 7, thereby causing the placement table 9 to rise. At the same time, the rising of the placement table 9 will cause the extrusion block 13 to rise, and the rotation of the movable rod 2 will drive the threaded block 11 to move through the threaded guide sleeve 10. The movement of the threaded block 11 will cause the trapezoidal block 12 to move, thereby causing the extrusion block 13 to always be in contact with the inclined surface of the trapezoidal block 12, thereby increasing the force-bearing area at the bottom of the placement table 9, making it more stable when in use.

[0043] A threaded hole is provided on the side of the rotating plate 3 , and a fastening bolt 4 is threadedly installed on the threaded hole. The other end of the fastening bolt 4 is tightly pressed against the side wall of the fixed base box 1 .

[0044] In this solution, the rotating plate 3 is conveniently fixed by setting the fastening bolts 4 .

[0045] Specifically, during use, the rotating plate 3 can be fixed by tightening the bolts 4 to prevent the rotating plate 3 from rotating and causing the placing platform 9 to drop.

[0046] In summary, when the utility model is used, firstly, the fixed base box 1 is placed at the installation site and the fixed cone is inserted into the soil for fixing. When it is fixed, the rotating plate 3 is rotated. The rotating plate 3 rotates to rotate the movable rod 2. The rotating movable rod 2 rotates to rotate the two first bevel gears 5. The rotating first bevel gears 5 rotate the two second bevel gears 7. The rotating second bevel gears 7 rotate the two screw rods 6. The rotating two screw rods 6 rotate under the action of the guide rod to move the two U-shaped blocks 8. The movement of the two U-shaped blocks 8 moves the placement table 9. The movement of the placement table 9 causes the support height to change. The support height can be changed and then adjusted, so that the height can be adjusted without selecting a suitable length of the top rod and welding. At the same time, the movement of the placement table 9 will drive the extrusion block 13 to move, and the rotation of the movable rod 2 will cause the threaded guide sleeve 10 to rotate, and the rotation of the threaded guide sleeve 10 will cause the two threaded blocks 11 to move, and the movement of the two threaded blocks 11 will cause the two trapezoidal blocks 12 to move, and the movement of the trapezoidal block 12 will cause its inclined surface to move, so that the inclined surface of the trapezoidal block 12 is always in contact with the extrusion block 13, thereby increasing the force area at the bottom of the placement table 9, making it more stable when in use.

[0047] When supporting, directly place the side of the plate to be supported containing the placement groove on the circular plate 19. At this time, the circular plate 19 is subjected to force to squeeze the lifting block 17 through the threaded rod 18 to make it move downward. The downward movement of the lifting block 17 will give a force to the slider 14 through the inclined plate 16. The slider 14 will slide under the force, and the movement of the slider 14 will cause the clamping plate 15 to move. The movement of the clamping plate 15 will cause the block 22 to move through the moving rod 21. When the block 22 contacts the object to be supported, the object to be supported continues to move downward, causing the clamping plate 15 to continue to move. At this time, the block 22 shrinks to avoid. When the bottom of the object to be supported contacts the top of the placement table 9, the two clamping plates 15 limit the object to be supported. At this time, the block 22 corresponds to the position of the placement groove, and the block 22 will reset under the action of the spring 24. The block 22 resets and moves into the placement groove, thereby limiting the object to be supported, so that it cannot move up and down, thereby automatically pressing it when the object to be supported is placed. The limited fixation reduces the fixing time. At the same time, when the width of the object to be supported changes, the circular plate 19 is rotated. The rotation of the circular plate 19 will cause the threaded rod 18 to rotate. The rotation of the threaded rod 18 will change the distance between the circular plate 19 and the top of the lifting block 17 through the threaded groove. At this time, placing the object to be supported will cause the moving distance of the bottom of the lifting block 17 to change. The change in the moving distance of the bottom of the lifting block 17 will cause the moving distance of the two sliders 14 to change, and then the spacing between the two clamping plates 15 after movement will change, so as to facilitate the limited fixation of objects to be supported with various widths. When dismantling, first pull the two pull plates 23. The pull plates 23 are subjected to force and the block 22 moves through the moving rod 21. When the block 22 moves out of the placement groove, the placement table 9 is moved downward or the object to be supported is moved. At this time, the lifting block 17 is not subjected to force and will be reset under the action of the tension spring 20, thereby resetting the two clamping plates 15, thereby releasing the limited fixation of the object to be supported.

[0048] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
