[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1-3, an embodiment provided by the present utility model: a protective device facilitating assembly, including a connecting frame 1 and a support frame 2. A support beam 3 is slidably connected between the connecting frame 1 and the support frame 2. A hollow column 4 is slidably connected inside the support beam 3. The hollow column 4 is slidably connected inside the support frame 2. A threaded column 5 is threadedly connected inside the hollow column 4. A handle 6 is fixedly connected to the top end of the threaded column 5. A connecting column 7 is fixedly connected to the bottom end of the threaded column 5. A tapered column 9 is slidably connected to the outer wall of the connecting column 7. A spring 8 is sleeved on the outer wall of the connecting column 7. The top end of the spring 8 is fixedly connected to the bottom end of the threaded column 5. The bottom end of the spring 8 is fixedly connected to the top end of the tapered column 9. A ball 10 is slidably connected inside the hollow column 4. The tapered column 9 is in contact with the ball 10. A connecting component is arranged inside the connecting frame 1, and the connecting component is used for the supporting function.

[0033] Specifically, when assembling the protective device, first insert the first rotating plate 11 and the second rotating plate 12 into the outer wall of the connecting shaft 20 respectively. Then, place the support beam 3 between the connecting frame 1 and the support frame 2, and insert the hollow column 4 into the corresponding mounting holes. Subsequently, by turning the handle 6, drive the threaded column 5 to rotate inside the hollow column 4. Relying on the threaded relationship between them, make the threaded column 5 push the connecting column 7 and the spring 8 connected to the bottom to start moving. The spring 8 is stressed to push the tapered column 9 connected to the bottom to move, and the tapered column 9 contacts the ball 10 inside the hollow column 4, causing the ball 10 to be stressed and slide out of the outside of the hollow column 4, and finally fixed between the support frame 2 and the connecting frame 1. At the same time, install the first connecting plate 17 and the second connecting plate 18 on the sliding plate 14 in this way, thus effectively completing the assembly of the protective device, not only simplifying the installation process, but also improving the stability and reliability of the device.

[0034] Refer to Figure 1 and Figure 4 , a slide rail 13 is fixedly connected to one side of the support frame 2. An electric push rod 16 is fixedly connected to the top of the slide rail 13. An output end of the electric push rod 16 is fixedly connected to a fixing plate 15. A sliding plate 14 is fixedly connected to the bottom of the fixing plate 15. The sliding plate 14 is slidably connected inside the slide rail 13. A first connecting plate 17 is arranged on the top of the sliding plate 14. One side of the first connecting plate 17 is fixedly connected to one side of the second rotating plate 12. A second connecting plate 18 is arranged on the top of the sliding plate 14. One side of the second connecting plate 18 is fixedly connected to one side of the first rotating plate 11. A support leg 19 is fixedly connected to the bottom of the slide rail 13.

[0035] Specifically, when the protective device needs to be opened and closed, the output end of the electric push rod 16 can be used to drive the fixing plate 15 to move. The fixing plate 15 is stressed to drive the sliding plate 14 connected to the bottom to slide inside the slide rail 13, so that the sliding plate 14 drives the first connecting plate 17 and the second connecting plate 18 installed on the top to start moving, achieving the effect of motion transmission.

[0036] Refer to Figure 1And Figure 4 The connecting component includes a connecting shaft 20. Two connecting shafts 20 are fixedly connected inside the connecting frame 1. A first rotating plate 11 is rotatably connected to the outer wall of one connecting shaft 20, and a second rotating plate 12 is rotatably connected to the outer wall of the other connecting shaft 20. One side of the first rotating plate 11 is in contact with one side of the second rotating plate 12.

[0037] Specifically, the second rotating plate 12 connected to the movement guiding side of the first connecting plate 17 rotates on the outer wall of the connecting shaft 20, while the movement of the second connecting plate 18 causes the first rotating plate 11 connected to one side to rotate on the outer wall of the connecting shaft 20. In this way, the second rotating plate 12 and the first rotating plate 11 complete the flipping and opening / closing actions between the connecting frame 1 and the support frame 2, enabling the protection device to achieve the opening / closing operation quickly and accurately, enhancing the operation convenience of the device, ensuring that it can be quickly adjusted and used when needed, and effectively improving the work efficiency and safety.

[0038] Working principle: When assembling the protection device, first insert the first rotating plate 11 and the second rotating plate 12 on the outer walls of the corresponding connecting shafts 20 respectively. Then place the support beam 3 between the connecting frame 1 and the support frame 2, and insert the hollow column 4 into the corresponding installation holes. At this time, turn the handle 6, and the force makes the threaded column 5 rotate inside the hollow column 4. Due to the threaded relationship between the hollow column 4 and the threaded column 5, the threaded column 5 moves inside the hollow column 4. The threaded column 5 pushes the connected column 7 and the spring 8 at the bottom to move. The spring 8 drives the tapered column 9 connected to the bottom end to move. During this process, the tapered column 9 contacts the ball 10 inside the hollow column 4, causing the ball 10 to slide out of the outside of the hollow column 4 and get stuck inside the support frame 2 and the connecting frame 1 to complete the fixation. At the same time, the first connecting plate 17 and the second connecting plate 18 are installed on the sliding plate 14 in this way, thus achieving the effect that the protection device is easy to assemble. When opening and closing the protection device, the output end of the electric push rod 16 drives the fixed plate 15 to move. The fixed plate 15 drives the sliding plate 14 connected to the bottom to slide inside the slide rail 13. The sliding plate 14 drives the first connecting plate 17 and the second connecting plate 18 installed on the top to move. The first connecting plate 17 drives the second rotating plate 12 connected to one side to rotate on the outer wall of the connecting shaft 20, and the second connecting plate 18 drives the first rotating plate 11 connected to one side to rotate on the outer wall of the connecting shaft 20. Furthermore, the second rotating plate 12 and the first rotating plate 11 perform flipping and opening / closing between the connecting frame 1 and the support frame 2, thus achieving the effect that the protection device can be quickly opened and closed.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
