Detailed Implementation
[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: a multifunctional emergency handrail, including a handrail body 1, with adjusting columns 2 fixedly connected to both sides of the handrail body 1, a rotating column 3 rotatably connected inside the adjusting column 2, an extension rod 4 slidably connected inside the rotating column 3, adjusting grooves 5 opened at both ends of the rotating column 3, a push block 6 slidably connected inside the adjusting groove 5, an insert block 7 fixedly connected to the side of the push block 6 near the inside of the adjusting groove 5, several slots 8 opened at both ends of the extension rod 4, and arc blocks 9 fixedly connected to both ends inside the adjusting column 2. The operator moves the extension rod 4 to adjust to the appropriate length, then rotates the rotating column 3, causing the rotating column 3 to drive the push block 6 and the insert block 7 to move synchronously, and the push block 6 to contact the thicker end of the arc block 9, causing the arc block 9 to push the push block 6 to drive the insert block 7 into the slot 8, thus fixing the position of the extension rod 4 and achieving the function of adjusting the length.
[0022] Reference Figures 2-5 As shown, in this embodiment, the size of the insert 7 is adapted to the size of the slot 8, and the surface of the insert 7 is inserted into the interior of the slot 8. By adapting the size of the insert 7 to the size of the slot 8, the insert 7 can be stably inserted into the interior of the slot 8 and is not easy to fall out, thus ensuring the stability and reliability of the structure.
[0023] Reference Figure 4 and Figure 5 As shown in this embodiment: both ends of the adjustment groove 5 are provided with sliding grooves 10, and both ends of the push block 6 are fixedly connected with sliders 11. The surface of the sliders 11 is slidably connected to the inside of the sliding groove 10. When the operator moves the push block 6, the push block 6 drives the sliders 11 to move inside the sliding groove 10. Through the above settings, the overall device is more stable during use and the movement process is smoother, avoiding the jamming or displacement phenomenon that may occur during the movement of traditional devices.
[0024] Reference Figure 5 As shown in this embodiment: a storage spring 12 is fixedly connected to the side of the push block 6 near the insertion block 7, and the side of the storage spring 12 away from the push block 6 is fixedly connected to the inside of the adjustment groove 5. When the operator pushes the push block 6 with the arc block 9, the push block 6 compresses the storage spring 12 to store force, and drives the insertion block 7 to insert into the inside of the slot 8. When the operator cancels the contact between the arc block 9 and the push block 6, the insertion block 7 can be firmly ejected under the action of the rebound force of the storage spring 12, thereby realizing the quick locking and unlocking function.
[0025] Reference Figure 3 and Figure 4 As shown in this embodiment: the adjusting column 2 has two annular grooves 13 inside, and the outer diameter of the rotating column 3 is fixedly connected to two annular blocks 14. The surface of the annular blocks 14 is slidably connected to the inside of the annular grooves 13. When the operator rotates the rotating column 3, the rotating column 3 drives the annular blocks 14 to slide inside the annular grooves 13. Through the above settings, the rotating column 3 is more stable during rotation, reducing errors caused by shaking. At the same time, the annular blocks 14 also play a certain guiding role during the sliding inside the annular grooves 13, making the rotation of the rotating column 3 smoother. In addition, this structure also increases the overall strength and durability, and extends the service life of the equipment.
[0026] Reference Figure 3 and Figure 5 As shown in this embodiment: both ends of the rotating column 3 are provided with shrinkage grooves 15, and the inside of the shrinkage groove 15 is slidably connected with a plug rod 17. The side of the plug rod 17 near the inside of the shrinkage groove 15 is fixedly connected with a return spring 16, and the side of the return spring 16 away from the plug rod 17 is fixedly connected to the inside of the shrinkage groove 15. Both ends of the adjusting column 2 are provided with insertion holes 18. When the operator limits the position of the plug block 7 and the slot 8, the position of the shrinkage groove 15 is parallel to the position of the insertion hole 18. At the same time, under the action of the return spring 16, the plug rod 17 is quickly pushed into the inside of the insertion hole 18, fixing the position of the rotating column 3 and preventing it from rotating.
[0027] Reference Figure 5 As shown in this embodiment: guide grooves 19 are provided at both ends of the shrinkage groove 15, and guide blocks 20 are fixedly connected to both ends of the insertion rod 17. The surface of the guide block 20 is slidably connected to the inside of the guide groove 19. When the operator moves the insertion rod 17, the insertion rod 17 drives the guide block 20 to slide inside the guide groove 19. Through the above setting, the insertion rod 17 can be effectively limited to prevent the insertion rod 17 from deviating or shaking during the movement, thereby improving the stability of the insertion rod 17 when moving and further improving the overall use effect.
[0028] Working principle: After adjusting the extension rod 4 to the appropriate length, the operator rotates the rotating column 3. This causes the rotating column 3 to move the push block 6 and the insertion block 7 synchronously, bringing the push block 6 into contact with the thicker end of the arc block 9. The arc block 9 then pushes the push block 6, causing the insertion block 7 to insert into the slot 8, thus fixing the position of the extension rod 4 and achieving the function of length adjustment. The size of the insertion block 7 is matched with the size of the slot 8, ensuring that the insertion block 7 can be stably inserted into the slot 8 without easily falling out, thus guaranteeing the stability and reliability of the structure. When push block 6 moves, it drives slider 11 to move inside slide groove 10. This design makes the entire device more stable during use and ensures smoother movement, avoiding the jamming or shifting that may occur with traditional devices. When the operator pushes push block 6 with arc block 9, push block 6 compresses and stores force in the energy storage spring 12, causing insert block 7 to insert into slot 8. When the operator removes the contact between arc block 9 and push block 6, the insert block 7 is securely ejected under the rebound force of the energy storage spring 12. This achieves rapid locking and unlocking. When the operator rotates the rotating column 3, the rotating column 3 drives the annular block 14 to slide inside the annular groove 13. This design makes the rotating column 3 more stable during rotation, reducing errors caused by shaking. Simultaneously, the annular block 14 also provides guidance during its sliding within the annular groove 13, making the rotation of the rotating column 3 smoother. Furthermore, this structure increases overall strength and durability, extending the equipment's lifespan. After the operator positions the insertion block 7 against the slot 8... The position of the shrink groove 15 is parallel to the position of the insertion hole 18. Under the action of the return spring 16, the insertion rod 17 is quickly pushed into the interior of the insertion hole 18, fixing the position of the rotating column 3 and preventing it from rotating. When the operator moves the insertion rod 17, the insertion rod 17 drives the guide block 20 to slide inside the guide groove 19. Through the above settings, the insertion rod 17 can be effectively limited, preventing the insertion rod 17 from deviating or shaking during the movement, thereby improving the stability of the insertion rod 17 when moving and further improving the overall use effect.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
