[0001] This utility model relates to the field of automobile repair, and in particular to a lift tripod with a plug-in anti-detachment mechanism. Background Technology

[0002] The lift tripod, as a key support structure, is widely used in various lifting equipment. Its unique triangular design effectively distributes and withstands the enormous pressure from above, ensuring stability and safety during the lifting process. This bracket is typically made of high-strength steel, precision-machined and rigorously quality-tested, possessing excellent pressure resistance and durability. Its simple yet robust structure not only facilitates installation and maintenance but also maintains stable support in complex working environments, making it an indispensable component of lifting equipment.

[0003] In the widely used lifting machines, the tripod bracket is an important component, and the telescopic bar is a key component of the tripod bracket. However, when the telescopic bar is subjected to large external forces, due to the limitations of its design and materials, it is prone to uneven stress, poor stability, and slippage. This situation not only directly affects the overall stability and operational safety of the lifting machine, creating significant hidden dangers during operation, but may also cause unpredictable potential hazards to on-site operators and surrounding equipment, and in severe cases, may even lead to accidents.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a lift tripod with a plug-in anti-detachment mechanism, comprising a vertical pole 1, a telescopic pole 2, and a base 5; a locking mechanism installed on the outer wall of the vertical pole 1 to prevent the telescopic pole 2 from slipping under force; and a fixing mechanism installed inside the vertical pole 1 for convenient installation of the base 5. The locking mechanism includes a fixing block 3, which is fixedly installed on the outer wall of the vertical pole 1. Slide rods 7 are fixedly connected to both sides of the inside of the fixing block 3. A clamping block 24 is slidably connected to the outer wall of one slide rod 7, and a clamping block 8 is slidably connected to the outer wall of the other slide rod 7. A gear 11 is rotatably connected inside the fixing block 3. A rack 10 is fixedly connected to the outer wall of the clamping block 24, meshing with the gear 11. A rack 9 is fixedly connected to the outer wall of the clamping block 24, meshing with the gear 11. A threaded post 6 is threadedly connected inside the fixing block 3, with one end of the threaded post 6 rotatably connected to the outer wall of the clamping block 24, and the other end of the threaded post 6 fixedly connected to a handle 4.

[0025] Specifically, to prevent the telescopic rod 2 from slipping, first operate the handle 4 to rotate the threaded column 6 fixedly connected to it. Because the threaded column 6 is threadedly connected to the fixing block 3 fixedly installed on the outer wall of the upright 1, the rotation of the threaded column 6 will produce stable axial movement. This movement can accurately push the clamping block 24, which is rotatably connected to one end, to prevent the clamping block 24 from shifting. The clamping block 24 is slidably connected to the slide rod 7 on one side inside the fixing block 3. Under the action of the thrust, it slides smoothly along the slide rod 7, effectively ensuring the regularity of the movement trajectory. At the same time, the rack 10 fixedly connected to its outer wall moves synchronously with the clamping block 24. The rack 10 and the fixing block The gear 11 inside the fixed block 3 is precisely engaged, driving the gear 11 to rotate smoothly. The gear 11 is also tightly engaged with the rack 9 fixedly connected to the outer wall of the clamping block 8, driving the rack 9 to move synchronously. The clamping block 8 is slidably connected to the slide rod 7 on the other side inside the fixed block 3. Driven by the rack 9, it slides along the slide rod 7 in the opposite direction to the clamping block 24. Finally, the clamping block 8 and the clamping block 24 approach each other and firmly clamp the telescopic rod 2, which can effectively prevent the telescopic rod 2 from slipping when under force, greatly improving the safety of the tripod during use and providing strong protection for the operation of equipment and the safety of operators.

[0026] When installing the upright 1 and the base 5, the upright 1 is aligned with the base 5 and inserted. The locking block 23, which is fixedly connected to the outer wall of the slider 22 inside the upright 1, will be squeezed by the inner wall of the base 5, causing the slider 22 to slide along the slide frame 21 into the upright 1 and compress the related moving parts. During this process, the parts fit tightly to avoid jamming. When the upright 1 is inserted into place and the locking block 23 is precisely aligned with the slot 12 opened inside the base 5, the squeezing force disappears. The slider 22 slides along the slide frame 21 under the reset action of the related parts, driving the locking block 23 to quickly insert into the slot 12 to achieve stable fixation. The entire installation process does not require complicated tools, is simple and quick to operate, and greatly saves installation time.

[0027] During disassembly, press the pressing rod 13, which is slidably connected inside the upright 1, so that it slides smoothly along the inner wall of the upright 1. The limiting post 15, which is slidably connected in the inclined groove 14 inside the pressing rod 13, will be pushed by the inner wall of the inclined groove 14. Due to the inclined design of the inclined groove 14, the pushing force can be efficiently converted into a force that drives the limiting post 15 to move upward, thereby driving the sliding column 16 to move upward stably. The sliding column 16 is slidably connected to the sliding rod 17 fixed inside the upright 1. When moving upward, it slides smoothly along the sliding rod 17 to prevent the sliding column 16 from deviating. At the same time, the spring 18 sleeved on the outer wall of the sliding rod 17 is compressed to produce elastic deformation, providing power for the subsequent reset of the components. The push block 1 is fixedly connected to the bottom of the sliding column 16. 9. Simultaneously move upwards, push block 19 is rotatably connected to transmission rod 20. When moving upwards, it can effectively pull one end of transmission rod 20. The other end of transmission rod 20 is rotatably connected to slider 22, which in turn pulls slider 22 to slide along slide frame 21 into the upright 1. This causes the locking block 23 to quickly retract into the upright 1 and disengage from the locking slot 12. At this time, the fixed relationship between upright 1 and base 5 is released, and upright 1 can be easily pulled out from base 5 to complete disassembly. The entire disassembly process is convenient and does not require too much manpower and time, which significantly improves the convenience of replacing the bracket base. When the base is damaged or needs to be replaced according to the usage scenario, it can be quickly replaced to ensure the normal use of the equipment in the future.

[0028] Working principle: To prevent the telescopic rod 2 from slipping, first operate the handle 4 to rotate the threaded column 6 fixedly connected to it. Because the threaded column 6 is threadedly connected to the fixing block 3 fixedly installed on the outer wall of the upright 1, the rotation of the threaded column 6 will cause axial movement and push the clamping block 24 rotatably connected to one end of it. The clamping block 24 is slidably connected to the slide rod 7 on one side inside the fixing block 3. Under the action of the thrust, it slides along the slide rod 7. At the same time, the rack 10 fixedly connected to its outer wall moves synchronously. The rack 10 meshes with the gear 11 rotatably connected inside the fixing block 3, driving the gear 11 to rotate. The gear 11 then meshes with the clamping block 24. 8. The rack 9, fixedly connected to the outer wall, engages, driving the rack 9 to move. The clamping block 8 is slidably connected to the slide rod 7 on the other side inside the fixed block 3. Driven by the rack 9, it slides along the slide rod 7 in the opposite direction to the clamping block 24. Finally, the clamping block 8 and the clamping block 24 move closer to each other and clamp the telescopic rod 2, ensuring safe use. When the upright 1 and the base 5 are installed, the upright 1 is inserted into the base 5. The locking block 23, which is fixedly connected to the outer wall of the slider 22 inside the upright 1, will be squeezed by the inner wall of the base 5, causing the slider 22 to slide along the slide frame 21 into the upright 1 and compress the related moving parts. When the upright 1 is inserted into the position... When the locking block 23 corresponds to the slot 12 inside the base 5, the squeezing force disappears, and the slider 22 slides along the slide frame 21 under the reset action of the relevant components, causing the locking block 23 to insert into the slot 12 for fixation. During disassembly, the pressing rod 13, which is slidably connected inside the upright 1, is pressed, causing it to slide along the inner wall of the upright 1. The limiting post 15, which is slidably connected in the inclined groove 14 inside the pressing rod 13, will be pushed by the inner wall of the inclined groove 14. Because the inclined groove 14 is inclined, the pushing force is converted into a force that drives the limiting post 15 to move upward, thereby driving the sliding post 16 to move upward. The sliding post 16 is fixed to the sliding rod 1 inside the upright 1. 7. Sliding connection. When moving upward, it slides stably along the second slide rod 17. At the same time, the spring 18 sleeved on the outer wall of the second slide rod 17 is compressed and produces elastic deformation. The push block 19 fixedly connected to the bottom of the slide column 16 moves upward synchronously. The push block 19 is rotatably connected to the transmission rod 20. When moving upward, it pulls one end of the transmission rod 20. The other end of the transmission rod 20 is rotatably connected to the slider 22. It pulls the slider 22 to slide along the slide frame 21 into the upright 1, causing the locking block 23 to retract into the upright 1 and disengage from the locking groove 12. At this time, the fixed relationship between the upright 1 and the base 5 is released, and the upright 1 can be pulled out from the base 5 to complete the disassembly, improving the convenience of base replacement.
