Abstract
Description
Technical Field
[0001] This invention relates to the field of safety engineering technology, specifically to a garden viewing platform with protective functions. Background Technology
[0002] Garden viewing platforms are man-made elevated structures in garden landscapes, usually located at higher elevations or scenic nodes. Constructed from materials such as wood, stone, and concrete, their core function is to provide visitors with elevated viewing angles for panoramic views of the garden layout, natural landscapes, or urban scenery. These platforms are often designed to blend seamlessly with the environment, combining practicality and artistry. They serve as visual focal points to guide visitor routes, while also meeting visitors' needs for photography, rest, and socializing. Furthermore, the elevated space enhances the interactive experience between people and the landscape, making them an important transitional space in garden design that connects man-made structures with natural landscapes.
[0003] The principle of garden viewing platforms is based on spatial elevation and sightline guidance. By raising the viewing height of visitors, the limitations of ground-level vision are broken, forming the best viewing angle for overlooking or looking into the distance. At the same time, the design of the landscape axis controls the direction of sight, allowing viewers to efficiently capture the layered beauty and overall layout of the garden. Platforms usually use steps, ramps or barrier-free access to guide the flow of people, and are equipped with railings, rest facilities and other features to enhance safety and comfort. Ultimately, the interaction between people and the landscape is optimized through spatial intervention, achieving the viewing effect of a small platform with a wide field of vision.
[0004] Since the viewing platform has a limited capacity, it becomes crowded during peak tourist seasons when tourists flock in, obstructing their view, reducing comfort, and thus lowering the overall tourist experience. In addition, excessive numbers of people can cause structural overload and trampling safety risks. Current methods often use sensors to control the flow of people, which can detect the number of people on the platform in real time, but the infrared accuracy is easily affected by strong light, and the cameras are interfered with by weather conditions such as rain and fog. Moreover, the sensor system is expensive, making its use solely for the viewing platform too costly. Summary of the Invention

[0017] Beneficial effects
[0018] The garden viewing platform with protective function provided by this invention has the following beneficial effects:
[0019] 1. When the number of people inside the observation platform reaches a critical value, the limiting block contacts the fixed block. The rotating plate cannot continue to slide under the restriction of the fixed block, and the limiting block contacts the inclined surface of the connecting slide rod under the action of the limiting frame. The connecting slide rod slides downward under the push of the limiting block, and by giving the inclined surface of the limiting slide rod a thrust, the limiting slide rod is pushed to be on the sliding path of the lifting block, thereby limiting the lifting block, thus limiting the three-roller gate on the side near the entrance channel, and thus limiting the flow of passengers entering the observation platform.
[0020] 2. When passengers enter the observation platform by pushing the tripod turnstile, the limiting slots on the surface of the limiting circular frame push the rotating circular plate to rotate, thereby causing the limiting block to rotate and gradually approach the fixed block. The distance between the limiting block and the fixed block is used to count the number of people on the observation platform. When a passenger leaves the observation platform through the exit passage, the pawl on the exit passage side pushes the rotating gear to rotate, and the contact rod drives the rotating circular plate to rotate, which in turn drives the rotating circular plate to rotate. The inclined surface of the limiting block retracts into the interior of slot number seven when it contacts the limiting slot, until it reaches the interior of the adjacent limiting slot, thereby automatically adjusting the number of people on the observation platform.
[0021] 3. When the number of passengers on the observation platform reaches the critical value, as the connecting slide bar slides downward, a thrust is applied to the inner wall of the inclined slide through the power shaft, which in turn pushes the inclined slide plate away from the warning board. Then, a pulling force is applied to the connecting block through the pulling shaft, which pulls the warning board to rotate 90 degrees, thus erecting a sign in the entrance passage to indicate that the number of passengers on the observation platform has reached the critical value, thereby avoiding safety hazards caused by excessive crowds on the observation platform.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] refer to Figures 1 to 10 According to a preferred embodiment of the present invention, a garden viewing platform with a protective function will be described in detail below, including a viewing platform 1, a staircase 11 fixedly connected to one side of the viewing platform 1, a classification box 12 provided at the connection between the viewing platform 1 and the staircase 11, an entry channel 13 and an exit channel 14 respectively provided on both sides of the classification box 12, characterized in that: a three-roller gate 2 is provided on both sides of the classification box 12 to ensure that tourists enter the viewing platform 1 one by one, a second ratchet 42 and a third ratchet 46 are provided inside the classification box 12 to count the tourists inside the viewing platform 1, and a limiting slide bar 52 is provided inside the classification box 12 to restrict the three-roller gate 2 on the entry channel 13 when the number of people on the viewing platform 1 reaches a critical value.
[0036] Two tripod turnstiles 2 are rotatably connected to both sides of the sorting box 12. The tripod turnstile 2 on the side closer to the entrance passage 13 rotates unidirectionally towards the viewing platform 1, and the tripod turnstile 2 on the side closer to the exit passage 14 rotates unidirectionally away from the viewing platform 1. The sorting box 12 has a first slot 21 and a second slot 23 symmetrically arranged inside. The first slot 21 and the second slot 23 are connected. The first gear 22 is rotatably connected inside the first slot 21, and the second gear 24 is rotatably connected inside the second slot 23. The first gear 22 and the second gear 24 mesh with each other. When a passenger pushes the tripod turnstile 2 into the viewing platform 1, the tripod turnstile 2 drives the second gear 24 to rotate through the first gear 22.
[0037] A lifting block 3 is fixedly connected to one side of the second gear 24. A third groove 32 is opened on one side of each of the two second grooves 23. A lifting rod 34 is slidably connected inside each of the two third grooves 32. A first spring 33 is fixedly connected inside each of the two third grooves 32. The first spring 33 is fixedly connected to the lifting rod 34. A fourth groove 35 is opened on one side of each of the two third grooves 32. A central swing shaft 39 is fixedly connected inside each of the two fourth grooves 35. A first swing rod 36 is rotatably connected to the surface of each of the two central swing shafts 39. A side swing block 37 is fixedly connected to one side of each of the two first swing rods 36. A swing groove 38 is opened on the surface of each side swing block 37. A face-holding shaft is slidably connected inside each of the two swing grooves 38. Both swing grooves 38 are fixedly connected to the face-holding shaft. The second gear 24 on the side closer to the entry channel 13 rotates, causing the lifting block 3 to rotate synchronously. The inclined surface of the lifting block 3 gives the lifting shaft 31 an upward thrust, which in turn pushes the lifting rod 34 with an upward thrust.
[0038] Each of the two slots 35 has a slot 4 on one side. The second ratchet 42 is rotatably connected to the interior of the slot 35 near the entrance passage 13, and the third ratchet 46 is rotatably connected to the interior of the slot 35 near the exit passage 14. The maximum number of people inside the viewing platform 1 is equal to the number of teeth on the surfaces of the second and third ratchet wheels 42 and 46. A first pawl 41 is rotatably connected to the surface of the first swing lever 36. The two first pawls 41 engage with adjacent ratchet wheels. A torsion spring is provided between the first swing lever 36 and the first pawl 41 to ensure that the first pawl 41 always maintains a tendency to engage with the ratchet. The first pawl 41 extends into the interior of the teeth on the surfaces of the second and third ratchet wheels 42 and 46. The teeth on the surfaces of the second and third ratchet wheels 42 are arranged in opposite directions. The surface of the second ratchet 42 is fixedly connected to a limiting circular frame 43. A rotating circular plate 45 is rotatably connected inside the limiting circular frame 43. A limiting slot 44 is formed on the surface of the limiting circular frame 43. A seventh slot 49 is formed inside the rotating circular plate 45. A limiting block 411 is slidably connected inside the seventh slot 49. A second spring 410 is fixedly connected inside the seventh slot 49 and is fixedly connected to the limiting block 411. A fixing block 412 is fixedly connected to the inner wall of the fifth slot 4, located on the sliding path of the limiting block 411. One end of the limiting block 411 has an inclined surface. A second contact rod 413 is fixedly connected to one side of the rotating circular plate 45. One end of the second contact rod 413 is fixedly connected to a rotating ratchet 414. The third ratchet... A first contact rod 47 is fixedly connected to one side of wheel 46. An adjusting toothed plate 48 is fixedly connected to one side of the first contact rod 47. A groove is provided inside the sorting frame 12. An extension push rod 415 is slidably connected inside the groove of the sorting frame 12. An extension spring 416 is fixedly connected inside the groove of the sorting frame 12. The extension spring 416 is fixedly connected to the extension push rod 415. The extension push rod 415 is Z-shaped and is not located inside the rotation path of the rotary ratchet 414. The surface of the adjusting toothed plate 48 is provided with tooth blocks. The number of tooth blocks on the surface of the adjusting toothed plate 48 is the same as the number on the surface of the third ratchet 46. One end of the extension push rod 415 extends into the tooth groove on the surface of the adjusting toothed plate 48. A second pawl 41 is rotatably connected to the surface of the extension push rod 415. 7. A locking shaft 418 is fixedly connected to the surface of the extension push rod 415, and a spring-loaded paddle 419 is also fixedly connected to the surface of the extension push rod 415. Both the locking shaft 418 and the spring-loaded paddle 419 are located on the rotation path of the second pawl 417. The locking shaft 418 is located above the second pawl 417, and the spring-loaded paddle 419 is located below the second pawl 417. The spring-loaded paddle 419 applies an upward elastic force to the second pawl 417. During the upward sliding process of the lifting rod 34, an upward thrust is applied to the side swing block 37 through the abutment shaft, which in turn pushes the first swing rod 36 to swing around the central swing shaft 39. This drives the second ratchet 42 to rotate through the first pawl 41, which in turn pushes the rotating circular plate 45 to rotate through the limiting slot 44 on the surface of the limiting circular frame 43.This causes the limiting block 411 to rotate and gradually move closer to the fixed block 412. The distance between the limiting block 411 and the fixed block 412 is used to count the number of people on the observation platform 1. As the second gear 24 gradually rotates, the lifting shaft 31 slides downwards again along the inclined surface of the lifting block 3, which in turn pulls the first pawl 41 back along the surface of the second ratchet 42 via the first swing rod 36. Under the action of the torsion spring, it extends back into the adjacent tooth block on the surface of the second ratchet 42.
[0039] A groove 5 is provided on the inner wall of groove 4 near the entrance channel 13. Groove 5 is L-shaped and extends horizontally into the interior of groove 23. A connecting rod 51 is slidably connected inside the vertical part of groove 5. A limiting rod 52 is slidably connected inside the horizontal part of groove 5. A contact plate 53 is fixedly connected to the lower surface of the limiting rod 52. A spring 54 is fixedly connected to the inner wall of groove 5. The contact plate 53 and the spring 54 are fixedly connected.
[0040] The connecting slide rod 51 extends into the interior of slot 4. One end of the connecting slide rod 51 has an inclined surface, which is located on the rotation path of the limiting block 411. The limiting slide rod 52 is located on the sliding path of the lifting block 3. An inclined surface is located above the end of the limiting slide rod 52 furthest from it, and this inclined surface is located on the sliding path of the connecting slide rod 51. When the number of people inside the viewing platform 1 reaches a critical value, the limiting block 411 contacts the fixed block 412, and the rotating circular plate 45... The fixed block 412 restricts the sliding, and the limiting block 411 contacts the inclined surface of the connecting slide rod 51 under the action of the limiting round frame 43. The connecting slide rod 51 slides downward under the push of the limiting block 411, and by giving a thrust to the inclined surface of the limiting slide rod 52, the limiting slide rod 52 is pushed to be located on the sliding path of the lifting block 3, thereby limiting the lifting block 3, thereby limiting the three-roller gate 2 on the side close to the entrance channel 13, and thus limiting the flow of passengers entering the viewing platform 1.
[0041] When a passenger leaves the observation platform 1 via exit passage 14, the first pawl 41 on one side of exit passage 14 pushes the third ratchet 46 to rotate, and the first contact rod 47 drives the adjusting toothed plate 48 to rotate. The teeth on the surface of the adjusting toothed plate 48 then push the extension push rod 415 to slide towards the rotary ratchet 414, causing the second pawl 417 to slide into the rotation path of the rotary ratchet 414, and pushing the rotary ratchet 414 to rotate. This, in turn, drives the second contact rod 413 to... The rotating circular plate 45 rotates, and the inclined surface of the limiting block 411 retracts into the interior of the seventh slot 49 under contact with the limiting slot 44, until it reaches the interior of the adjacent limiting slot 44, thereby realizing the automatic adjustment of the number of people count on the viewing platform 1. The adjusting tooth plate 48 continues to rotate, and the extension push rod 415 extends back into the tooth groove of the adjusting tooth plate 48 under the push of the extension spring 416. The second pawl 417 disengages from the rotation path of the rotating ratchet 414 under the drive of the extension push rod 415.
[0042] The inner wall of slot 8 (5) has slot 9 (6). A sliding plate 62, L-shaped, is slidably connected inside slot 9 (6). A sliding groove 63 is formed on the surface of the sliding plate 62. A drive shaft 61 is fixedly connected to the surface of the connecting rod 51, and the drive shaft 61 is slidably connected inside the sliding groove 63. An extension groove 67 is formed on the surface of the sorting box 12. A prompting plate 68 is rotatably connected inside the extension groove 67. A connecting pull block 64 is fixedly connected to the surface of the prompting plate 68. A pull block 64 is formed on the surface of the connecting pull block 64. A pull shaft 6 is slidably connected inside the pull block 64. 5. The pull shaft 65 is fixedly connected to the inclined slide plate 62. When the number of passengers on the viewing platform 1 reaches the critical value, during the downward sliding of the connecting slide rod 51, the power shaft 61 provides a thrust to the inner wall of the inclined slide groove 63, thereby pushing the inclined slide plate 62 to slide away from the indicator board 68. Then, the pull shaft 65 provides a pulling force to the connecting pull block 64, thereby pulling the indicator board 68 to rotate 90 degrees, thus erecting a sign in the entrance passage 13, thereby indicating that the number of passengers on the viewing platform 1 has reached the critical value, thus avoiding safety hazards caused by excessive number of people on the viewing platform 1.
[0043] The following is the complete working process and working principle of the above embodiment: When a passenger enters the observation platform 1 by pushing the tripod turnstile 2, the tripod turnstile 2 drives the second gear 24 to rotate through the first gear 22. The rotation of the second gear 24 near the entrance channel 13 drives the lifting block 3 to rotate synchronously. The inclined surface of the lifting block 3 provides an upward thrust to the lifting shaft 31, which in turn pushes the lifting rod 34 with an upward thrust. During the upward sliding process of the lifting rod 34, it provides an upward thrust to the side swing block 37 through the abutment shaft, which in turn pushes the first swing rod 36 to swing around the central swing shaft 39, and pushes the second pawl through the first pawl 41. The wheel 42 rotates, which in turn pushes the rotating plate 45 to rotate through the limiting slot 44 on the surface of the limiting circular frame 43. This causes the limiting block 411 to rotate and gradually move closer to the fixed block 412. The distance between the limiting block 411 and the fixed block 412 is used to count the number of people on the viewing platform 1. As the second gear 24 rotates, the lifting shaft 31 slides down along the inclined surface of the lifting block 3. Then, the first swing rod 36 pulls the first pawl 41 to slide back along the surface of the second ratchet 42. Under the action of the torsion spring, it extends back into the adjacent tooth block on the surface of the second ratchet 42.
[0044] When the number of people inside the viewing platform 1 reaches the critical value, the limiting block 411 contacts the fixed block 412. The rotating circular plate 45 cannot continue to slide under the restriction of the fixed block 412. The limiting block 411 contacts the inclined surface of the connecting slide rod 51 under the drive of the limiting circular frame 43. The connecting slide rod 51 slides downward under the push of the limiting block 411. By giving a thrust to the inclined surface of the limiting slide rod 52, the limiting slide rod 52 is pushed to be located on the sliding path of the lifting block 3, thereby limiting the lifting block 3, thereby limiting the three-roller gate 2 on the side close to the entrance channel 13, thereby limiting the flow of passengers entering the viewing platform 1.
[0045] When a passenger leaves the observation platform 1 via exit passage 14, the first pawl 41 on one side of exit passage 14 pushes the third ratchet 46 to rotate, and the first contact rod 47 drives the adjusting toothed plate 48 to rotate. The teeth on the surface of the adjusting toothed plate 48 then push the extension push rod 415 to slide towards the rotary ratchet 414, causing the second pawl 417 to slide into the rotation path of the rotary ratchet 414, and pushing the rotary ratchet 414 to rotate. This, in turn, drives the second contact rod 413 to... The rotating circular plate 45 rotates, and the inclined surface of the limiting block 411 retracts into the interior of the seventh slot 49 under contact with the limiting slot 44, until it reaches the interior of the adjacent limiting slot 44, thereby realizing the automatic adjustment of the number of people count on the viewing platform 1. The adjusting tooth plate 48 continues to rotate, and the extension push rod 415 extends back into the tooth groove of the adjusting tooth plate 48 under the push of the extension spring 416. The second pawl 417 disengages from the rotation path of the rotating ratchet 414 under the drive of the extension push rod 415.
[0046] When the number of passengers on viewing platform 1 reaches the critical value, as the connecting slide bar 51 slides downward, a thrust is applied to the inner wall of the inclined slide 63 via the power shaft 61, which in turn pushes the inclined slide plate 62 to slide away from the indicator board 68. Then, a pulling force is applied to the connecting pull block 64 via the pulling shaft 65, which pulls the indicator board 68 to rotate 90 degrees, thereby erecting a sign in the entrance passage 13 to inform passengers that the number of passengers on viewing platform 1 has reached the critical value, thus avoiding safety hazards caused by excessive number of people on viewing platform 1.
[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
