Description

A folding rod device and its telescopic method Technical Field

[0001] This invention relates to the field of railing technology, specifically to a folding rod device and its extension / retraction method. Background Technology

[0002] Currently, the driveway barriers and parking lot entrance / exit barriers used in the market all adopt single-pole or two-fold barrier solutions. When facing extra-wide driveways or entrances / exits, both of these solutions have limitations. If a standard-length barrier is used, the barrier length is insufficient to cover the width, failing to provide complete blocking. If an extra-long barrier is used, the height exceeds the equipment housing significantly when folded or retracted, affecting the equipment's appearance and posing safety hazards. More importantly, it cannot be used in areas with low ceilings or indoor roofs. Another solution is to install one device at each end of the access point. This doubles the number of devices required and increases the demands on synchronous control of the devices at both ends. Summary of the Invention

[0052] Preferably, the third rotation point 18 on the inverted triangular piece 9 is rotatably connected to one end of the second push-pull rod 13, and the second rotation point 17 on the inverted triangular piece 9 is rotatably connected to the second push-pull rod 16. The connecting segments of the second push-pull rod 13, the second push-pull rod 16 and the second push-pull rod 13 and the second push-pull rod 16 on the inverted triangular piece 9 and the equilateral triangular piece 22 form a parallelogram.

[0053] A first stabilizing link 20 and a second stabilizing link 23 are provided between the second push-pull rod 13 and the second push-pull rod 26. The two ends of the first stabilizing link 20 are rotatably connected to the middle sections of the second push-pull rod 13 and the second push-pull rod 26, respectively. The two ends of the second stabilizing link 23 are rotatably connected to the ends of the second push-pull rod 13 and the second push-pull rod 26 away from the inverted triangular piece 9, respectively.

The third railing connecting plate 29 is rotatably connected to the first bending point 31 on the fourth railing connecting plate 30. The fourth railing connecting plate 30 is fixedly connected to a fifth reinforcing block 33. The fifth reinforcing block 33 is fixedly connected to the third railing 34.

[0055] Preferably, the fourth reinforcing block 21 is rotatably connected to the second connection point 26 of the equilateral triangular member 22;

[0056] The second push-pull rod 13 is provided with a second slide groove 28. The third connection point 27 of the equilateral triangle 22 is slidably connected to the second slide groove 28. One end of the second push-pull plate 32 is rotatably connected to the third connection point 27 of the equilateral triangle 22. The other end of the second push-pull plate 32 is rotatably connected to the middle section of the fifth reinforcing block 33.

[0057] The second push-pull rod 16 is provided with a first slide groove 24, and the first connection point 25 of the equilateral triangular piece 22 is slidably connected in the first slide groove 24.

[0058] The working principle and beneficial effects of the above scheme are as follows:

[0059] The first railing 7, the first push-pull rod 6, the inverted triangular piece 9 and their corresponding connection points are combined to form a parallelogram linkage structure, which enables the inverted triangular piece 9 to translate in the XY plane when the motor shaft outputs.

[0060] The first railing 7 is fixedly connected to the first railing connecting plate 10, and the second railing 15 is fixed to the second railing connecting plate 11. The two railings are connected by a hinge point through the second bending point 35.

[0061] The inverted triangular piece 9 is hinged to the first railing 7.

[0062] The first push-pull plate 12 is hinged to the inverted triangular piece 9, and is also hinged to the second railing 15.

[0063] The second railing 15 can rotate relative to the first railing 7 around the hinge point. As described above, the inverted triangular piece 9 translates in the XY plane. When the inverted triangular piece 9 translates, it forces the second railing 15 to follow the first railing 7 in either an upright or horizontal direction, only the direction of the motion vectors is opposite. At this time, because the inverted triangular piece 9 pushes the first push-pull plate 12, the angle of the second railing 15 relative to the first railing 7 changes. When the railing is retracted, the inverted triangular piece 9 pulls the first push-pull plate 12. Therefore, when the first railing 7 rotates counterclockwise, the second railing 15 rotates clockwise relative to it, and vice versa. This achieves the straightening and folding functions of the first and second railing sections.

[0064] The connection between the third railing 34 and the second railing 15 is the same as that between the first railing 7 and the second railing 15.

[0065] The equilateral triangular piece 22 is hinged to the second railing 15.

[0066] The second push-pull plate 32 is connected to the hinge point of the equilateral triangle piece 22, and is also connected to the hinge point of the third railing 34.

[0067] The parallel support formed by the second push-pull rod 13 and the second push-pull rod 16, the inverted triangular piece 9, and the equilateral triangular piece 22 are connected by a hinge point to form a variable parallelogram mechanism. The purpose of the parallelogram mechanism is to ensure that the equilateral triangular piece 22 moves in the same direction as the inverted triangular piece 9 in the XY plane. The translation speed of the equilateral triangular piece 22 is N times that of the inverted triangular piece 9 (N is determined by the length difference between the second railing 15 and the first railing 7).

[0068] The third railing 34 can rotate relative to the second railing 15 around the hinge point. Similar to the description of the first railing 7 and the second railing 15 above, the equilateral triangle 22 translates in the XY plane. When the equilateral triangle 22 translates, the second push-pull plate 32 forces the third railing 34 to follow the second railing 15 in either an upright or horizontal direction, only the direction of the motion vector is opposite. At this time, because the equilateral triangle 22 pushes the second push-pull plate 32, the angle of the third railing 34 relative to the second railing 15 changes. When the railing is retracted, the equilateral triangle 22 pulls the second push-pull plate 32. Therefore, when the second railing 15 rotates clockwise, the third railing 34 rotates counterclockwise, and vice versa. This achieves the straightening and folding function of the second and third railing sections.

[0069] When the first railing 7 moves vertically or horizontally, the second railing 15 rotates in the opposite direction to the first railing 7, and the third railing 34 rotates in the same direction as the first railing 7, thus realizing the straightening and folding function of the three-fold railing.

[0070] This application, driven by a single drive unit (one motor system), achieves a sufficiently long extended length while maintaining a sufficiently low folded height (fully accommodated by a standard-sized chassis), making it adaptable to a wider range of scenarios (especially those with low-height roofs). It eliminates the risk of railing collapse after erection, allows for convenient transport by installing the railing inside the equipment (long-pole transport requires sufficiently long vehicles), simplifies control (similar to single-pole control), and offers a more cost-effective production and installation option (requiring only a single drive unit). Example 2

[0071] Please refer to Figure 9. Based on Embodiment 1, the drive body 1 is provided with a drive motor for driving the folding rod body 4 to rotate. The drive rotation point 3 of the folding rod body 4 is connected to the output end of the drive motor, and a stabilization component is provided on the drive rotation point 3.

[0072] The stabilization component includes a fixing plate 37, which is fixedly connected to the drive body 1. The fixing plate 37 is provided with a mounting plate 42, which is provided with a mounting hole 43. A linkage shaft 39 is inserted into the mounting hole 43. The linkage shaft 39 is provided with a snap-fit ​​surface 40. A connecting block 36 and a threaded section 41 are respectively provided at both ends of the linkage shaft 39. The connecting block 36 is fixedly connected to the drive rotation point 3.

[0073] A stabilizing component 44 is fixedly connected to the mounting plate 42. A through hole 45 is provided on the stabilizing component 44. A stabilizing groove 46 is provided on the outer periphery of the through hole 45. The linkage shaft 39 is inserted into the through hole 45.

[0074] The linkage shaft 39 is fitted with a stabilizing component 47, a spring 49, and a synchronizing pad 50. The stabilizing component 47 is provided with a first snap-fit ​​hole 48, and the synchronizing pad 50 is provided with a second snap-fit ​​hole 51. The first snap-fit ​​hole 48 and the second snap-fit ​​hole 51 are adapted to the snap-fit ​​plane 40 on the linkage shaft 39.

[0075] The mating stabilizer 47 is provided with a protrusion that matches the stabilizing groove 46;

[0076] The spring 49 abuts against the mating stabilizer 47 and the synchronizing pad 50;

[0077] A nut 52 is threadedly connected to the threaded section 41 of the linkage shaft 39.

[0078] Preferably, the fixing plate 37 is provided with fixing holes 38, and the fixing plate 37 and the driving body 1 are fixedly connected through the fixing holes 38.

[0079] The working principle and beneficial effects of the above scheme are as follows:

[0080] During the use of railings, accidents such as power outages and drive failures are inevitable. To ensure the safety of the railings in the event of such accidents, stabilization components are installed to enhance their safety.

[0081] To prevent the railing from suddenly falling and causing danger when it loses power, a linkage shaft 39 is connected to the power shaft of the railing, maintaining their relative stillness, i.e., ensuring they move in the same direction. Since the linkage shaft 39 has a locking surface 40 that engages with the stabilizing component 47 and the synchronizing pad 50, the movement of the linkage shaft 39 drives the stabilizing component 47 and the synchronizing pad 50. Because the stabilizing component 47 has a protrusion that matches the stabilizing groove 46, the movement of the stabilizing component 47 compresses the spring 49, causing the protrusion on the stabilizing component 47 to separate from the stabilizing groove 46, completing the movement. During this process, the energy stored in the spring 49 reduces the speed at which the railing descends, effectively ensuring the safety of the railing in case of an accident. Example 3

[0085] During recycling, the first railing 7, the second railing 15, and the third railing 34 rotate and close at the connection point.

[0086] The working principle and beneficial effects of the above scheme are as follows:

[0087] When the first railing 7 moves vertically or horizontally, the second railing 15 rotates in the opposite direction to the first railing 7, and the third railing 34 rotates in the same direction as the first railing 7, thus realizing the straightening and folding function of the three-fold railing.

[0088] This application, driven by a single drive unit, has a sufficiently long extended length and a sufficiently low folded height, making it adaptable to a wider range of scenarios. It eliminates the risk of the railing collapsing after being erected, and the railing can be installed inside the equipment for convenient transportation, simpler control, and more advantageous production and installation costs.
