Description

Technical Field

[0001] This utility model relates to the field of climbing frame technology, specifically to a climbing frame protective device. Background Technology

[0002] Play climbing frames are facilities for children to play in playgrounds or outdoor activities. These climbing frames are usually made of metal or plastic and are designed in various shapes and sizes for children to climb, crawl and explore.

[0003] According to a public disclosure of a climbing frame safety device (Publication No.: CN 221601134 U), it includes a climbing frame column, with slide rails fixedly connected to both sides of the inner wall of the climbing frame column, a slide plate provided on the inner wall of the slide rail, a counterweight fixedly connected to one end of the slide plate, and a toothed plate fixedly connected to the other end of the slide plate.

[0004] However, in the above design, the cooperation of components such as climbing frame columns and sliding rails makes it difficult to cushion a child's fall when landing on the top of the support plate. Instead, the child will collide with the round bars on the inner wall of the climbing frame, which reduces the child's safety during play and increases the degree of external injury to the child's body. This design needs to be improved. Utility Model Content

[0005] This utility model proposes a climbing frame protection device, which solves the problems mentioned in the above documents.

[0006] The technical solution of this utility model is as follows: it includes a support leg and a climbing frame. The climbing frame is set on the top of the support leg. A round rod is fixedly connected to the inner wall of the climbing frame. A pad is set at the bottom of the climbing frame. A protective shock-absorbing device is set inside the pad. The protective shock-absorbing device includes a round groove. The round groove is opened at the bottom of the inner wall of the pad. A round shaft is slidably connected to the inner wall of the round groove. A force-bearing plate is fixedly connected to the top of the round shaft. A spring is fixedly connected to the bottom of the inner wall of the pad. The end of the spring away from the bottom of the inner wall of the pad is fixedly connected to the bottom of the force-bearing plate.

[0007] According to the above design scheme, a locking block is fixedly connected to the side of the force plate, a sliding groove is opened on the side of the support leg, a moving plate is slidably connected to the inner wall of the sliding groove, a locking groove is opened on the side of the moving plate, an action spring is fixedly connected to the inner wall of the locking groove, and a rectangular plate is fixedly connected to the end of the action spring away from the inner wall of the locking groove. This design is conducive to the moving plate sliding on the inner wall of the sliding groove.

[0008] According to the above design scheme, the initial state of the spring is set to a relaxed state, and several circular shafts are arranged in a linear array on the inner wall of the pad. The spring is located directly above the circular groove. This design is beneficial for the spring to play a buffering role on the force plate.

[0009] According to the above design scheme, a protective mechanism is provided on the side of the support leg. The protective mechanism includes a protective plate, which is fixedly connected to the side of the support leg. A rotating rod is rotatably connected to the inner wall of the protective plate. A force-bearing rod is fixedly connected to the circumferential surface of the rotating rod, and a baffle is fixedly connected to the circumferential surface of the rotating rod. This design is beneficial because when the force-bearing rod is subjected to pressure, the force-bearing rod drives the rotating rod to perform an arc-shaped motion.

[0010] According to the above design scheme, the inner wall of the protective plate is provided with a groove, and a force spring is fixedly connected to the inner wall of the groove. An elastic soft plate is fixedly connected to the end of the force spring away from the inner wall of the groove, and a torsion spring is fixedly connected to the circumferential surface of the rotating rod. This design is conducive to the elastic soft plate sliding on the inner wall of the groove through the force spring.

[0011] According to the above design, the angle between the force-bearing rod and the inner wall of the protective plate is less than 90 degrees. There are two force-bearing springs, which are symmetrical to each other along the vertical central axis of the top of the protective plate. This design helps the protective plate to protect children.

[0012] According to the above design scheme, the side section of the pad is set to be concave, the side section of the protective plate is set to be concave, and the locking block is slidably connected to the inner wall of the slide groove. This design is conducive to the locking block being able to slide on the inner wall of the slide groove through the force plate.

[0013] According to the above design scheme, the movable plate is fixedly connected to the bottom of the climbing frame. One end of the rectangular plate is set as an adaptive arc surface, and one end of the card block is set as an adaptive arc surface. This design is beneficial because when the arc surface of the card block and the arc surface of the rectangular plate come into contact with each other, the rectangular plate can retract into the inside of the card slot.

[0014] According to the above design scheme, the baffle is located on the side above the force-bearing rod, and one end of the baffle is set as an adaptive arc surface. There are two baffles, which are symmetrical to each other along the vertical central axis of the bottom of the climbing frame. This design is conducive to the baffles blocking one side of the protective plate.

[0015] According to the above design scheme, there are two rotating rods, which are symmetrical to each other along the vertical central axis of the bottom of the climbing frame. The height of the supporting legs is different. This design is conducive to the force-bearing rod making arc-shaped movements through the rotating rods.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, components such as a round shaft, spring, locking block, and force plate work together to achieve the following: when the force plate moves upward, the locking block fixed to the side of the force plate pushes the rectangular plate, causing the rectangular plate to drive the moving plate to slide upward on the inner wall of the slide groove. This allows the climbing frame to be raised, so that when a child falls to the top of the force plate, the child is cushioned and will not collide with the round rod on the inner wall of the climbing frame, thus protecting the child's safety during play and reducing the degree of external injury to the child's body.

[0018] 2. In this utility model, the force-bearing rod, baffle, groove, force-bearing spring, and other components work together to achieve the following: when the rotating rod is subjected to force and makes an arc-shaped movement, the baffle fixed on the circumference of the rotating rod also makes an arc-shaped movement. This can block the side of the protective plate, preventing children from falling to the ground from one side of the protective plate and causing injury. Because the elastic soft plate is elastic and soft, it has a cushioning effect when the child falls, reducing the pain of the child's fall and ensuring the child's safety. The torsion spring fixed on the circumference of the rotating rod can reset the rotating rod after the child leaves. Attached Figure Description

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-5 As shown, this embodiment proposes a climbing frame protection device, including a support leg 1 and a climbing frame 2. The climbing frame 2 is set on the top of the support leg 1. A round rod 3 is fixedly connected to the inner wall of the climbing frame 2. A pad 4 is set at the bottom of the climbing frame 2. A protective shock absorption device 5 is set inside the pad 4. The protective shock absorption device 5 includes a round groove 51, which is opened at the bottom of the inner wall of the pad 4. A round shaft 52 is slidably connected to the inner wall of the round groove 51. A force-bearing plate 53 is fixedly connected to the top of the round shaft 52. A spring 54 is fixedly connected to the bottom of the inner wall of the pad 4. One end of the spring 54 away from the bottom of the inner wall of the pad 4 is fixedly connected to the bottom of the force-bearing plate 53.

[0029] A locking block 55 is fixedly connected to the side of the force plate 53, and a sliding groove 56 is provided on the side of the support leg 1. A movable plate 57 is slidably connected to the inner wall of the sliding groove 56. A locking groove 58 is provided on the side of the movable plate 57. An action spring 59 is fixedly connected to the inner wall of the locking groove 58. A rectangular plate 510 is fixedly connected to the end of the action spring 59 away from the inner wall of the locking groove 58. This design facilitates the sliding of the movable plate 57 on the inner wall of the sliding groove 56.

[0030] The initial state of the spring 54 is set to a relaxed state. Several circular shafts 52 are arranged linearly on the inner wall of the pad 4. The spring 54 is located directly above the circular groove 51. This design helps the spring 54 to buffer the force plate 53.

[0031] In this embodiment, when a child is playing on the climbing frame 2, if the child accidentally falls between the round bars 3, the child will fall onto the force plate 53. The force plate 53 will then slide downwards along the inner wall of the round groove 51 via the round shaft 52. The spring 54 fixed to the bottom of the force plate 53 will cushion the impact of gravity, preventing serious injury to the child upon fall. When the child falls to the top of the force plate 53, the force plate 53 moves downwards, causing the locking block 55 fixed to the side of the force plate 53 to move downwards. This causes the arc-shaped surface of the locking block 55 to contact the arc-shaped surface of the rectangular plate 510, compressing the rectangular plate 510 and causing it to retract via the spring 59. Inside the groove 58, when the locking block 55 and the rectangular plate 510 are no longer in contact, the rectangular plate 510 loses its squeezing force and resets through the action of the spring 59, thus placing the locking block 55 below the rectangular plate 510. Since the force plate 53 can be reset by the spring 54, when the force plate 53 moves upward, the locking block 55 fixed to the side of the force plate 53 pushes the rectangular plate 510, causing the rectangular plate 510 to drive the moving plate 57 to slide upward on the inner wall of the groove 56, allowing the climbing frame 2 to be lifted upward. This cushions the child's fall onto the top of the force plate 53, preventing the child from colliding with the round rod 3 on the inner wall of the climbing frame 2, protecting the child's safety during play and reducing the degree of external injury to the child's body.

[0032] Example 2

[0033] like Figures 3-5 As shown, based on the same concept as Embodiment 1 above, a second embodiment is also proposed. A protective mechanism 6 is provided on the side of the support leg 1. The protective mechanism 6 includes a protective plate 61, which is fixedly connected to the side of the support leg 1. A rotating rod 62 is rotatably connected to the inner wall of the protective plate 61. A force-bearing rod 63 is fixedly connected to the circumferential surface of the rotating rod 62, and a baffle 64 is fixedly connected to the circumferential surface of the rotating rod 62. This design is beneficial because when the force-bearing rod 63 is subjected to pressure, the force-bearing rod 63 drives the rotating rod 62 to undergo arc-shaped motion under force.

[0034] The inner wall of the protective plate 61 has a groove 65, and a force spring 66 is fixedly connected to the inner wall of the groove 65. An elastic soft plate 67 is fixedly connected to the end of the force spring 66 away from the inner wall of the groove 65. A torsion spring 68 is fixedly connected to the circumferential surface of the rotating rod 62. This design facilitates the sliding of the elastic soft plate 67 on the inner wall of the groove 65 by the force spring 66.

[0035] The angle between the force-bearing rod 63 and the inner wall of the protective plate 61 is less than 90 degrees. There are two force-bearing springs 66, which are symmetrical to each other along the vertical central axis of the top of the protective plate 61. This design helps the protective plate 61 to protect children.

[0036] The side section of the pad 4 is set to be concave, the side section of the protective plate 61 is set to be concave, and the locking block 55 is slidably connected to the inner wall of the slide groove 56. This design is conducive to the locking block 55 being able to slide on the inner wall of the slide groove 56 through the force plate 53.

[0037] The movable plate 57 is fixedly connected to the bottom of the climbing frame 2. One end of the rectangular plate 510 is set as an adaptive arc surface, and one end of the locking block 55 is set as an adaptive arc surface. This design is beneficial because when the arc surface of the locking block 55 comes into contact with the arc surface of the rectangular plate 510, the rectangular plate 510 can retract into the interior of the locking slot 58.

[0038] The baffle 64 is located on the side above the force-bearing rod 63. One end of the baffle 64 is set as an adaptive arc surface. There are two baffles 64, which are symmetrical to each other along the vertical central axis of the bottom of the climbing frame 2. This design is conducive to the baffle 64 blocking one side of the protective plate 61.

[0039] There are two rotating rods 62, which are symmetrical to each other along the vertical central axis of the bottom of the climbing frame 2. The height of the supporting legs 1 is different. This design is conducive to the force-bearing rod 63 making arc-shaped movements through the rotating rods 62.

[0040] In this embodiment, in the protective shock absorption device 5, if a child falls from either side of the climbing frame 2 and lands on the top of the elastic soft plate 67, the elastic soft plate 67, under the force of gravity, slides downward on the inner wall of the groove 65 through the elastic force of the force spring 66, thereby generating pressure on the force rod 63. This pressure causes the force rod 63 to move downward in an arc shape through the rotating rod 62. When the rotating rod 62 moves in an arc shape, the baffle 64 fixed on the circumference of the rotating rod 62 also moves in an arc shape, which can block the side of the protective plate 61, preventing the child from falling to the ground from one side of the protective plate 61 and causing injury. Because the elastic soft plate 67 is elastic and soft, it provides a cushioning effect when the child falls, reducing the pain of the fall and ensuring the child's safety. The torsion spring 68 fixed on the circumference of the rotating rod 62 can reset the rotating rod 62 after the child leaves.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
