There are a first installation part and a second installation part at both ends of the support rod assembly to provide a position for rotational connection. The main brake rod 10 and the auxiliary brake rod 20 are respectively rotatably installed on the support rod assembly through the first installation part and the second installation part, and the main brake rod 10 and the auxiliary brake rod 20 are arranged in parallel.

[0049] In this embodiment, a plurality of vertical rods 30 with the same length and evenly distributed are arranged between the main brake rod 10 and the auxiliary brake rod 20. Among them, the main brake rod 10 and the auxiliary brake rod 20 form a rotational connection with the vertical rods 30 through a movable connection assembly. In this way, when the main brake rod 10 and the auxiliary brake rod 20 rotate around the corresponding installation parts, the vertical rods 30 can rotate accordingly and maintain an upright state.

[0050] It can be understood that in this embodiment, through the coordinated movement among the support rod assembly, the main brake rod 10, the auxiliary brake rod 20 and the vertical rods 30, it is beneficial to realize the quick installation and disassembly of the brake rod, improve the installation efficiency, and the vertical rods 30 can maintain an upright state, enhancing the overall stability and reliability of the brake rod.

[0051] In this embodiment, first sealing plates 12 are provided at both ends of the main brake rod 10, and second sealing plates 21 are provided at both ends of the auxiliary brake rod 20; since the brake rod is usually installed in various environments, during daily use, there may be dust, debris and other fine particles in the surrounding environment. The sealing plates can block these foreign matters from entering the inside of the brake rod, avoiding the normal operation of the internal structure of the brake rod being affected due to the accumulation of foreign matters.

[0052] Specifically, when the main brake rod 10 and the auxiliary brake rod 20 respectively rotate around the first installation part and the second installation part to the pole-raising position, the ends of the plurality of vertical rods 30 are inclined at a specific angle and stacked in sequence, and the adjacent vertical rods 30 are closely closed; when the main brake rod 10 and the auxiliary brake rod 20 respectively rotate around the first installation part and the second installation part to the pole-lowering position, the ends of the vertical rods 30 are flush, and there is a gap between the adjacent vertical rods 30, which can save space when raising the pole and provide a wider entrance for vehicles to pass through, and can play an effective blocking role when lowering the pole.

[0053] In this embodiment, the main brake rod 10 has a hollow structure, and a reinforcing rod 11 is provided in the hollow part; the hollow main brake rod 10 reduces the weight while ensuring the strength, and the reinforcing rod 11 enhances the strength of the main brake rod 10.

[0054] Further, the strut assembly includes a first strut 501 and a second strut 502. A strut connection seat 53 is connected between the first strut 501 and the second strut 502. The first strut 501 and the second strut 502 are respectively arranged on both sides of the plane where the main brake rod 10 and the auxiliary brake rod 20 are located, and the two ends are respectively rotationally connected to the main brake rod 10 and the auxiliary brake rod 20 through strut shafts; specifically, the first end of the strut assembly is connected to the main brake rod 10 through a first strut shaft 51, and the second end of the strut assembly is connected to the auxiliary brake rod 20 through a second strut shaft 52. Among them, strut brackets 503 are provided on both the main brake rod 10 and the auxiliary brake rod 20, and the first strut shaft 51 and the second strut shaft 52 are respectively arranged on the corresponding strut brackets 503.

[0055] It can be understood that in this embodiment, the design of the strut assembly ensures the support stability and rotational flexibility of the brake rod, enables the brake rod to have sufficient strength and stability, is convenient for rotational operation at the same time, and improves the service life and reliability of the brake rod.

[0056] In this embodiment, the auxiliary brake rod 20 is located below the main brake rod 10, and a buffer strip 22 is provided on the bottom surface of the auxiliary brake rod 20. The buffer strip 22 is used to play a buffering role when the brake rod falls, reduce the impact force, can protect the brake rod and the ground, extend the service life of the brake rod, and reduce noise and vibration at the same time.

[0057] Please refer to Figure 2 and Figure 3 , further, seats are fixedly provided on both the main brake rod 10 and the auxiliary brake rod 20; among them, a plurality of main rod seats 13 are uniformly and fixedly provided on the main brake rod 10, and a plurality of auxiliary rod seats 23 are uniformly and fixedly provided on the auxiliary brake rod 20.

[0058] Please refer to Figure 4 , the movable connection assembly includes an intermediate connection seat 42 for connecting the vertical rod 30 to the main rod seat 13 and for connecting the vertical rod 30 to the auxiliary rod seat 23. The first end of the intermediate connection seat 42 is fixedly connected to the vertical rod 30, and the second end is rotationally connected to the seat. The connection and rotation between the vertical rod 30 and the seat are realized through the intermediate connection seat 42, which ensures that the vertical rod 30 can rotate relative to the main brake rod 10 and the auxiliary brake rod 20, makes the rotational movement of the brake rod smoother, and improves the flexibility and operability of the brake rod.

[0059] Please refer to Figure 5 and Figure 6, in this embodiment, hollow cavities are provided at both ends of the vertical rod 30, and a plug-in portion detachably inserted into the hollow cavity is provided at the first end of the intermediate connecting seat 42. An elastic clamping portion 41 is provided on the cavity wall of the hollow cavity, and a first hook portion 421 is provided on the intermediate connecting seat 42. The two are tightly clamped and engaged to firmly fix the intermediate connecting seat 42 in the vertical rod 30. The quick connection and fixation of the intermediate connecting seat 42 and the vertical rod 30 are realized through the cooperation of elastic clamping and hooks, which is beneficial to making the installation and disassembly more convenient and fast, and improves the efficiency of production and maintenance.

[0060] In this embodiment, a first mounting hole 422 is provided at the second end of the intermediate connecting seat 42, and a boss 45 is provided on the support. Among them, the intermediate adapter seat 42 is provided with a positioning groove 424 for positioning the boss 45; a second mounting hole 451 is provided on the boss 45, and the first mounting hole 422 and the second mounting hole 451 are rotatably connected through a rotating shaft member 43. The intermediate connecting seat 42 and the support are connected by the rotating shaft member 43 to realize the rotation function, which enables the vertical rod 30 to rotate smoothly, enhances the flexibility and adaptability of the gate rod, and meets the rotation requirements at different angles.

[0061] Please refer to Figure 7 , in this embodiment, a second hook portion 431 is provided at one end of the rotating shaft member 43, and a stepped clamping portion 423 is provided on the hole wall of the first mounting hole 422. The two are clamped to limit the rotating shaft member 43 in the first mounting hole 422; a hook limiting structure 4231 is provided on the stepped clamping portion 423, and the second hook portion 431 is limited in the hook limiting structure 4231, and the hook limiting structure 4231 is used to prevent the rotating shaft member 43 from rotating relative to the intermediate connecting seat 42. It can be understood that the hook limiting structure 4231 is in the shape of a limiting groove, and the limiting groove can be formed by two adjacent convex blocks or by a convex block with a groove; in addition, a plurality of the hook limiting structures 4231 can be provided, so that when the rotating shaft member 43 is inserted into the intermediate connecting seat 42 at any angle, the limiting in the hook limiting structure 4231 can be quickly realized.

[0062] At the same time, a ring-shaped enclosure 432 is provided at the other end of the rotating shaft member 43, and the ring-shaped enclosure 432 can complement the clamping relationship in which the rotating shaft member 43 is limited in the first mounting hole 422, so that the rotating shaft member 43 can be fixedly connected to the intermediate connecting seat 42.

[0063] It can be understood that, on the basis of the foregoing structure, the rotating shaft member 43 is fixed in the first mounting hole 422 of the intermediate connecting seat 42 by means of hooks and stepped clamping, preventing the rotating shaft member 43 from falling off, ensuring the stability of the rotating shaft member 43, and making the rotation movement more reliable.

[0064] Please refer to Figure 8, Further, the movable connection component further includes a rotating shaft cover 44. The front end of the rotating shaft cover 44 is inserted into the rotating shaft member 43. The front end of the rotating shaft cover 44 is provided with a third hook portion 441, and the outer wall of the rotating shaft member 43 is provided with a groove-shaped clamping portion 433. The two are clamped. When the rotating shaft cover 44 is clamped to the rotating shaft member 43, the second hook portion 431 on the rotating shaft member 43 will only be clamped to the stepped clamping portion 423. Therefore, the second hook portion 431 will not rebound, so that the rotating shaft member 43 is stably held in the first mounting hole 422. When replacing the accessories, first pull out the rotating shaft cover 44. At this time, the second hook portion 431 on the rotating shaft member 43 can rebound inward, and then the rotating shaft member 43 can be taken out. The rotating shaft member 43 is further fixed by the rotating shaft cover 44 to prevent the rotating shaft member 43 from loosening, improving the connection stability of the rotating shaft member 43 and further enhancing the overall reliability of the brake lever.

[0065] The rotating shaft member 43 has a hollow structure, which can reduce the weight, lower the material cost, and also make the rotation of the vertical rod 30 light and smooth.

[0066] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of the present application, the patent protection scope of the present application cannot be limited thereby. Any technical solution obtained by equivalent structure or equivalent process substitution or modification based on the essential concept of the present application and using the content recorded in the text and drawings of the specification of the present application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are all included in the patent protection scope of the present application.
