Description

Technical Field

[0001] This utility model relates to the field of impact resistance technology, specifically a positioning device for an impact-resistant support column. Background Technology

[0002] Impact-resistant support columns are structural components specifically designed to resist impact forces. Through material optimization, structural innovation, and buffering mechanisms, they disperse and absorb impact energy, employing high-strength alloy steel or modified nylon and other special materials. For example, the Zhuoao Shipeng lifting column uses alloy steel containing manganese, chromium, and nickel, significantly improving hardness and toughness. In high-speed vehicle collisions, it effectively disperses impact force, preventing deformation and breakage. Its impact resistance is enhanced through solid columns, high-strength tubing, or hollow interconnected structures. Hydraulic support columns feature hollow piston structures, connecting the central cylinder to the piston cavity. This allows the fluid to form a buffer wave during impact, reducing the hydraulic elastic coefficient and extending the impact duration. Bed support columns utilize a vertical support layout, distributing the weight of the body and mattress to the main beam to prevent bed collapse.

[0003] Impact-resistant support columns effectively disperse and buffer impact forces during use, ensuring structural stability under external impact. In emergencies such as earthquake rescue, impact-resistant support columns provide temporary support for rescuers, preventing further collapse of damaged or unstable buildings and ensuring their safety. Simultaneously, their stable support provides survival space for trapped personnel, increasing the success rate of rescue. In coal mine hydraulic supports, impact-resistant columns can withstand the rock pressure of shallow-buried coal seam mining. Modified nylon hexagonal spacers in electronic systems, through fatigue resistance and dimensional stability, reduce component loosening caused by vibration or impact. The protective coating and buffering device of alloy steel lifting columns work synergistically to reduce impact damage and extend overall service life. During use, support columns require assembly with extension plates to fit snugly against the building wall. However, the assembly process at the support column's connection point requires multiple connecting components to fix the extension plate, making it cumbersome. Furthermore, the installation angle of the extension plate needs adjustment during installation, thus reducing the effectiveness of the assembly between the extension plate and the support column.

[0021] Example 1 Reference Figure 1-4This first embodiment of the present invention provides a positioning device for an impact-resistant support column, comprising a base 1, a support column 2, a connecting seat 3, two mounting plates 4, two extension plates 5, and two fixing blocks 6. The support column 2 is located on the top of the base 1 and is movably connected to the top of the base 1 via a pivot. The connecting seat 3 is located on the top of the support column 2 and is movably connected to the top of the support column 2 via a pivot. The two mounting plates 4 are located on the left and right sides of the inner cavity of the connecting seat 3 and are inserted into and fitted into the inner cavity of the connecting seat 3. The two extension plates 5 are located on opposite sides of the two mounting plates 4 and are fixedly connected to the surface of the mounting plates 4. The two fixing blocks 6 are located on the left and right sides of the front side of the connecting seat 3 and are fixedly connected to the front side of the connecting seat 3. The top and bottom of the inner cavity of the fixing block 6 are provided with an assembly mechanism 7 that cooperates with the extension plate 5. The inner cavity of the fixing block 6 is provided with a drive mechanism 8 that cooperates with the assembly mechanism 7.

[0022] Specifically, after the expansion plate 5 is connected to the connector 3, the drive mechanism 8 can quickly drive the assembly mechanism 7 and the U-shaped block 9 to cooperate with each other, so as to quickly plug and fix the expansion plate 5, thus avoiding the situation where the expansion plate 5 cannot be quickly assembled and fixed.

[0023] Furthermore, the expansion plate 5 is docked with the connector 3. During the docking process, the assembly plate 4 needs to be inserted into the inner cavity of the connector 3. After the docking is completed, the drive mechanism 8 is started. The drive mechanism 8 will drive the assembly mechanisms 7 on both sides to move. During the movement, the assembly mechanisms 7 will quickly assemble and fix the expansion plate 5 through the U-shaped block 9, thereby achieving the effect of quickly assembling and fixing the expansion plate 5.

[0024] Example 2 In the second embodiment of this utility model, the assembly mechanism 7 includes a lead screw 701, a bevel gear 702, a moving plate 703, and a positioning pin 704. The lead screw 701 is located in the inner cavity of the fixed block 6 and is movably connected to the inner wall of the fixed block 6 via a rotating shaft. The protruding end of the bevel gear 702 is rotatably connected to the inner wall of the fixed block 6, and the side of the bevel gear 702 near the lead screw 701 is fixedly connected to the surface of the lead screw 701. The inner cavity of the moving plate 703 is threadedly connected to the surface of the lead screw 701. The side of the positioning pin 704 near the moving plate 703 is fixedly connected to the surface of the moving plate 703. The front side of the extension plate 5 is fixed. A U-shaped block 9 is connected, and the top and bottom of the inner cavity of the U-shaped block 9 are provided with insertion holes 10. The side of the positioning pin 704 away from the moving plate 703 is inserted and fitted into the inner cavity of the insertion hole 10. The top and bottom of the inner cavity of the expansion plate 5 are fixedly connected with T-shaped blocks 11, and the surface of the T-shaped blocks 11 is inserted and fitted into the inner wall of the assembly plate 4. The top and bottom of the opposite sides of the two fixing blocks 6 are provided with sliding holes 12, and the inner wall of the sliding holes 12 is slidably connected to the surface of the moving plate 703. The top and bottom of the expansion plate 5 are provided with assembly holes 13, which are used to connect and fix the assembly plate 4 to the building wall panel with expansion bolts.

[0025] Specifically, the assembly mechanism 7 enables the rapid connection and fixation of the expansion plate 5 through the cooperation of the assembly plate 4, the connecting seat 3, and the U-shaped block 9. Furthermore, the installation angle of the expansion plate 5 can be easily adjusted through the pivot connection between the support column 2 and the connecting seat 3.

[0026] Furthermore, the expansion plate 5 is docked with the connecting seat 3. During the docking process, the assembly plate 4 needs to be inserted into the inner cavity of the connecting seat 3. When the assembly plate 4 is inserted into the inner cavity of the connecting seat 3, it needs to be inserted and fitted with the T-block 11. After the expansion plate 5 is docked with the connecting seat 3 through the assembly plate 4, the effect of stable docking between the assembly plate 4 and the connecting seat 3 can be achieved. During the rotation output of the straight bevel gear 702, it will drive the lead screw 701 to rotate. When the lead screw 701 rotates, it will drive the positioning pin 704 to move through the threaded connection with the moving plate 703. During the movement of the moving plate 703, it will move through the threaded connection with the positioning pin 704. The mutual cooperation of the sliding holes 12 ensures its own movement stability. When the moving plate 703 drives the positioning pin 704 to insert into the inner cavity of the insertion hole 10, the U-shaped block 9 can lock and fix the extension plate 5, thus completing the stable installation of the extension plate 5. After the extension plate 5 is installed, the connecting seat 3 can be rotated and adjusted by the pivot connection between the support column 2 and the connecting seat 3. When the connecting seat 3 and the extension plate 5 are rotated to an angle that can fit against the building wall, the extension plate 5 and the connecting seat 3 are connected to the building wall. After the connection is completed, the extension plate 5 can be connected and fixed to the building wall by expansion bolts through the assembly hole 13.

[0027] Example 3 In the third embodiment of this utility model, the drive mechanism 8 includes a rotary motor 801, a support plate 802, and a connecting gear 803. The rotary motor 801 is located on the front side of the fixed block 6, and its output end is rotatably connected to the inner wall of the fixed block 6. The connecting gear 803 is located on the rear side of the rotary motor 801 and is fixedly connected to the output end of the rotary motor 801. The top and bottom of the connecting gear 803 are meshed with the teeth of the straight bevel gear 702. The support plate 802 is located on the top of the rotary motor 801 and is fixedly connected to the top of the rotary motor 801. The rear side of the support plate 802 is fixedly installed to the front side of the fixed block 6 by bolts.

[0028] Specifically, the drive mechanism 8 can quickly drive the assembly mechanism 7 to be used by cooperating with the assembly mechanisms 7 on both sides, thus avoiding the situation where the expansion plate 5 cannot be installed and fixed by the assembly mechanism 7.

[0029] Furthermore, after the extension plate 5 is connected to the connecting seat 3, the rotary motor 801 is started. The rotary motor 801 will drive the connecting gear 803 to rotate through its own output end. During the rotation, the connecting gear 803 will drive the teeth of the straight bevel gear 702 to rotate through its own teeth, thereby achieving the effect of quickly driving the assembly mechanisms 7 on both sides for stable use.

[0030] Working principle: The expansion plate 5 is aligned with the connecting seat 3. During alignment, the assembly plate 4 needs to be inserted into the inner cavity of the connecting seat 3. When the assembly plate 4 is inserted into the inner cavity of the connecting seat 3, it needs to be inserted and fitted with the T-block 11. After the expansion plate 5 is aligned with the connecting seat 3 through the assembly plate 4, the assembly plate 4 and the connecting seat 3 are stably aligned. The rotary motor 801 is started. The rotary motor 801 drives the connecting gear 803 to rotate through its output end. During the rotation of the connecting gear 803, the teeth of the connecting gear 702 drive the teeth of the bevel gear 702 to rotate. During the rotation output of the bevel gear 702, the lead screw 701 is driven to rotate. When the lead screw 701 rotates, it will interact with the moving plate. The threaded connection of 703 drives the positioning pin 704 to move. During the movement, the moving plate 703 ensures its stability by cooperating with the sliding hole 12. When the moving plate 703 drives the positioning pin 704 to insert into the inner cavity of the insertion hole 10, the U-shaped block 9 can lock and fix the extension plate 5, thus completing the stable installation of the extension plate 5. After the extension plate 5 is installed, the connecting seat 3 can be rotated and adjusted by the pivot connection between the support column 2 and the connecting seat 3. When the connecting seat 3 and the extension plate 5 are rotated to an angle that can fit against the building wall, the extension plate 5 and the connecting seat 3 are connected to the building wall. After the connection is completed, the extension plate 5 can be connected and fixed to the building wall by expansion bolts through the assembly hole 13.

[0031] In summary, through the cooperation of the base 1, support column 2, connecting seat 3, assembly plate 4, extension plate 5, fixing block 6, assembly mechanism 7 and drive mechanism 8, the effect of quickly assembling and fixing the extension plate 5 is achieved.

[0032] The base 1, support column 2, connecting seat 3, assembly plate 4, extension plate 5, fixing block 6, lead screw 701, bevel gear 702, moving plate 703, rotary motor 801, and connecting gear 803 used in this application can be additionally equipped with protective measures of common knowledge in this technical field under different usage environments.
