Description

Technical Field

[0001] This utility model relates to the field of gate arm reinforcement technology, and in particular to a double main rod reinforcement gate arm connection device. Background Technology

[0002] Strengthening gate arms refers to the technical means or processes used to improve the overall strength, stability and resistance to damage of gate arms by optimizing structural design, adding auxiliary components or improving connection methods. These are commonly found in the core load-bearing components of equipment such as barrier gates, access control gates, and parking gates. The ultimate goal is to make the gate arms less prone to deformation, breakage or loosening of connections during long-term use, when bearing loads or coping with external impacts such as wind and collisions.

[0003] A search revealed a Chinese utility model patent, CN201686951U, which discloses a gate arm connecting device. The device includes: a connector comprising a drive device connecting end and a positioning part connecting end; a positioning part comprising a positioning part and a gate arm connecting end; and a connecting shaft connecting the positioning part connecting end and the positioning part, allowing the positioning part to rotate around the connecting shaft. This utility model's gate arm connecting device can mitigate external impacts by overcoming frictional resistance, enhancing safety. It is low-cost, safe, reliable, highly operable, and adaptable, with numerous user-friendly designs for ease of use.

[0004] When used by users, the aforementioned patents rely on a single connection point or a small number of connecting parts to bear the load, resulting in the stress on the gate arm being concentrated in a local area during operation, which can easily lead to overload damage at a single connection point. At the same time, the overall resistance to deformation is weak, which shortens the service life of the gate arm. Furthermore, the installation flexibility and adaptability are poor, and the stability of the entire connection device after installation is insufficient, affecting the operating accuracy of the gate arm.

[0005] Therefore, a double-main-rod reinforced gate arm connection device is particularly needed. Utility Model Content

[0006] The purpose of this utility model is to provide a double main rod reinforced gate arm connection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double main rod reinforced gate arm connection device, comprising a device body, a connecting plate movably connected to the side surface of the device body, and a docking connection mechanism installed on the side surface of the connecting plate; The docking connection mechanism includes a sleeve ring mounted on a connecting plate. A fixing block is fixedly connected to one side of the sleeve ring, and a nut is fixedly connected to one side of the fixing block. A cylindrical guide rod is fixedly connected to one side of the main body of the device. A sleeve frame is movably connected to one side of the cylindrical guide rod. A fixing rod is fixedly connected to one side of the sleeve frame. A connecting base plate is fixedly connected to one side of the fixing rod, and a support column is fixedly connected to one side of the connecting base plate.

[0008] Preferably, a limiting insert shaft is inserted into the inner ring surface of the main body of the device, and the limiting insert shaft passes through the connecting plate and is connected thereto.

[0009] Preferably, a limiting head is fixedly connected to one side of the cylindrical guide rod, and the limiting head and the socket frame are structurally compatible.

[0010] Preferably, the inner surface of the socket frame has a snap-fit ​​opening, and the size of the snap-fit ​​opening and the cylindrical guide rod are matched.

[0011] Preferably, a reinforcing rod is fixedly connected to one side of the socket frame, and there are multiple reinforcing rods.

[0012] Preferably, a threaded rod is movably connected to one side of the nut, and the threaded rod is connected to the nut and the fixing block.

[0013] Preferably, the socket frame is connected to the connecting base plate by a fixing rod, and the fixing rod is arranged around the connecting base plate as the center point.

[0014] Preferably, the nut is connected by a fixing block and a sleeve ring, and the fixing block is symmetrically arranged with the vertical center line of the nut as the axis of symmetry.

[0015] Preferably, a mounting flange is fixedly connected to one side of the support column, and the mounting flange is connected to the support column and the connecting base plate.

[0016] Preferably, one side of the mounting flange has a mounting opening, and the number of mounting openings is multiple.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. The device body and the connecting plate are stably connected by the set limit pin. With the ring distribution of multiple fixed rods and reinforcing rods in the docking connection mechanism, as well as the rigid support of the support column and the mounting flange, the stress on the gate arm can be effectively distributed, avoiding overload damage at a single connection point.

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a double main rod reinforced gate arm connection device, including a device body 1, a connecting plate 4 movably connected to the side surface of the device body 1, and a docking connection mechanism 3 installed on the side surface of the connecting plate 4; The docking connection mechanism 3 includes a sleeve ring 301, which is mounted on the connecting plate 4. A fixing block 311 is fixedly connected to one side of the sleeve ring 301, and a nut 312 is fixedly connected to one side of the fixing block 311. A cylindrical guide rod 302 is fixedly connected to one side of the main body 1. A sleeve frame 305 is movably connected to one side of the cylindrical guide rod 302. A fixing rod 306 is fixedly connected to one side of the sleeve frame 305. A connecting base plate 308 is fixedly connected to one side of the fixing rod 306, and a support column 309 is fixedly connected to one side of the connecting base plate 308. When using a double-main-rod reinforced gate arm connection device, the connecting plate 4 is attached to the side surface of the device body 1, and the limiting insert 2 is inserted from the inner ring surface of the device body 1, passing through the connecting plate 4, thus completing the initial limiting connection between the device body 1 and the connecting plate 4. The sleeve ring 301 in the docking connection mechanism 3 is fixedly installed on the side surface of the connecting plate 4. The nut 312 and the sleeve ring 301 are fixedly connected by fixing blocks 311 symmetrically arranged with the vertical center line of the nut 312 as the axis of symmetry. Then, the threaded rod 313 is screwed into the nut 312, initially... First, lock the position of the locking ring 301, align the socket frame 305 with the cylindrical guide rod 302 fixed on one side of the main body 1 through the snap-fit ​​opening 304 on the inner ring surface, and push the socket frame 305 to make it fully fit with the cylindrical guide rod 302. At this time, the limiting head 303 on one side of the cylindrical guide rod 302 fits with the socket frame 305 structure to prevent the socket frame 305 from falling off. Using the fixing rod 306 arranged around the connecting base plate 308 as the center point, fix the socket frame 305 to the connecting base plate 308. At the same time, multiple reinforcing rods 3 on one side of the socket frame 305 are used to fix it. 07. Strengthen the connection between the socket frame 305 and the fixing rod 306; then fix the connecting base plate 308 and the mounting flange 310 through the support column 309 to form a complete support structure. Through the multiple mounting openings 314 on one side of the mounting flange 310, fix the entire device in the designated installation position; finally, tighten the threaded rod 313, and adjust the tightness of the socket ring 301 by cooperating with the nut 312 and the fixing block 311 to ensure that the main body 1, the connecting plate 4 and the docking connection mechanism 3 form a stable double main rod connection system, and complete the entire installation process.

[0023] Furthermore, the inner ring surface of the device body 1 is fitted with a limiting shaft 2, and the limiting shaft 2 passes through the connecting plate 4 and is connected. The limiting shaft 2 can directly pass through the device body 1 and the connecting plate 4 to form a double limiting structure, which prevents the two from lateral displacement or relative rotation during the operation of the gate arm. This lays a solid foundation for the subsequent installation of the docking connection mechanism 3, and simplifies the initial assembly steps without the need for additional complex fasteners. Furthermore, a limiting head 303 is fixedly connected to one side of the cylindrical guide rod 302, and the limiting head 303 and the sleeve frame 305 are structurally compatible. The limiting head 303 can block the sleeve frame 305 from the end after the sleeve frame 305 is connected to the cylindrical guide rod 302, preventing it from falling off along the axial direction of the cylindrical guide rod 302. Especially when the gate arm is frequently raised and lowered and vibrates, it can ensure the stability of the connection part and avoid safety hazards caused by the falling off of the parts. Furthermore, the inner surface of the socket frame 305 is provided with a snap-fit ​​opening 304, and the snap-fit ​​opening 304 and the cylindrical guide rod 302 are matched in size. The snap-fit ​​opening 304 can realize the quick alignment and snap-fit ​​between the socket frame 305 and the cylindrical guide rod 302, and the initial connection can be completed without precise alignment, which greatly reduces the installation difficulty. At the same time, the matching size design can ensure that there is no gap after the two are connected, reduce the shaking of the gate arm during operation, and improve the rigidity of the connection part. Furthermore, a reinforcing rod 307 is fixedly connected to one side of the socket frame 305, and there are multiple reinforcing rods 307. The multiple reinforcing rods 307 can be evenly distributed at the connection node between the socket frame 305 and the fixed rod 306 to form multi-directional support, disperse the radial force borne by the socket frame 305, and avoid the single connection point from breaking or deforming due to force concentration. Especially when the double main rods bear large loads, it can significantly enhance the fatigue resistance of the overall structure. Furthermore, a threaded rod 313 is movably connected to one side of the nut 312, and the threaded rod 313 is connected to the fixing block 311 through the nut 312. The engagement of the threaded rod 313 and the nut 312 allows for flexible adjustment of the tightness of the sleeve ring 301. This allows for adjustment of the fit between the connecting plate 4 and the docking mechanism 3 according to actual needs during installation, and also allows for the tightening of the threaded rod 313 after long-term use to compensate for gaps caused by component wear, ensuring the stability of the connection. Furthermore, the socket frame 305 is connected to the connecting base plate 308 via the fixing rod 306, and the fixing rod 306 is arranged around the connecting base plate 308 with the connecting base plate 308 as the center point. The surrounding fixed rod 306 can evenly transfer the force of the socket frame 305 to the connecting base plate 308, avoiding the damage to the local structure caused by the concentration of force. At the same time, it forms a symmetrical support structure, so that the connecting base plate 308 is balanced by force, further improving the load-bearing capacity of the entire docking connection mechanism 3. Furthermore, the nut 312 is connected to the fixing block 311 and the sleeve ring 301, and the fixing block 311 is symmetrically arranged with the vertical center line of the nut 312 as the axis of symmetry. The symmetrical fixing block 311 can ensure that the nut 312 is subjected to uniform force, avoid the nut 312 tilting or loosening due to force on one side, and at the same time enhance the connection strength between the nut 312 and the sleeve ring 301, prevent the fixing block 311 from breaking during the tightening of the threaded rod 313, and ensure the reliability of the adjustment structure. Furthermore, a mounting flange 310 is fixedly connected to one side of the support column 309, and the mounting flange 310 is connected to the connecting base plate 308 through the support column 309. The support column 309 can raise the distance between the connecting base plate 308 and the mounting flange 310, reserving sufficient operating space for installation and facilitating subsequent fixing operations through the mounting flange 310. At the same time, the rigid structure of the support column 309 can transmit the force of the connecting base plate 308, so that the mounting flange 310 is evenly loaded and avoids local overload. Furthermore, a mounting flange 310 is fixedly connected to one side of the support column 309, and the mounting flange 310 is connected to the connecting base plate 308 through the support column 309. The mounting flange 310 serves as a connection carrier between the device and the external structure, and the device can be stably fixed by bolts and other connecting parts. The connection method of the support column 309 can ensure that the mounting flange 310 and the connecting base plate 308 remain perpendicular, avoiding tilting of the device after installation and ensuring the verticality and stability of the double main rod gate during operation.

[0024] Working principle: When the user needs to use a double-main-rod reinforced gate arm connection device, the connecting plate 4 is attached to the side surface of the device body 1, and the limiting insert 2 is inserted from the inner ring surface of the device body 1, so that it passes through the connecting plate 4, completing the initial limiting connection between the device body 1 and the connecting plate 4. The sleeve ring 301 in the docking connection mechanism 3 is fixedly installed on the side surface of the connecting plate 4. The nut 312 and the sleeve ring 301 are fixedly connected by the fixing block 311 symmetrically arranged with the vertical center line of the nut 312 as the axis of symmetry. Then, the threaded rod 313 is screwed into the nut 312 to initially lock the position of the sleeve ring 301. The sleeve frame 305 is aligned with the cylindrical guide rod 302 fixed on one side of the device body 1 through the snap-fit ​​opening 304 on the inner ring surface. The sleeve frame 305 is pushed to make it fully fit with the cylindrical guide rod 302. At this time, the cylindrical guide rod 302... The limiting head 303 on the side fits structurally with the socket frame 305 to prevent the socket frame 305 from falling off. The socket frame 305 is fixedly connected to the connecting base plate 308 by using the fixing rod 306 arranged around the connecting base plate 308 as the center point. At the same time, the connection strength between the socket frame 305 and the fixing rod 306 is enhanced by multiple reinforcing rods 307 on one side of the socket frame 305. Then, the connecting base plate 308 is fixedly connected to the mounting flange 310 by the support column 309 to form a complete support structure. The entire device is fixed in the designated installation position by multiple installation openings 314 on one side of the mounting flange 310. Finally, the threaded rod 313 is tightened, and the tightness of the socket ring 301 is adjusted by the cooperation of the nut 312 and the fixing block 311 to ensure that the main body 1, the connecting plate 4 and the docking connection mechanism 3 form a stable double main rod connection system, thus completing the entire installation process.
