Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0024] Embodiment 1

[0025] Reference Figures 1-6 ​​The utility model provides a children's playground device with safety protection, which comprises a pair of support plates 1, a linkage shaft 2 is rotatably installed at the upper end of the support plates 1, a swing seat is connected to the middle part of the linkage shaft 2 through a pair of linkage plates 3, an installation cavity is arranged in the support plates 1, the two ends of the linkage shaft 2 are located at the upper end of the installation cavity and are connected with traction ropes 4, the lower end of the traction ropes 4 extends to the lower end of the installation cavity and is connected with linkage seats 5, limit grooves 6 are arranged at the upper end of the linkage seats 5, adjusting columns 7 are arranged in the limit grooves 6, limit rods 8 are inserted into the adjusting columns 7, and a plurality of adjusting holes 9 are arranged in the inner wall of the limit grooves 6 in correspondence with the limit rods 8.

[0026] Embodiment 2

[0027] Reference Figures 1-6 In the case that other parts are the same as those in embodiment 1, the embodiment differs from embodiment 1 in that:

[0028] A plurality of positioning grooves 10 are arranged in the slot opening extending to the surface of the support plates 1, one end of the limit rods 8 extending to the outer side of the support plates 1 is in rectangular shape and is inserted into the positioning grooves 10, compression springs 11 are arranged in the limit grooves 6, the upper end of the compression springs 11 is fixed to the lower end of the adjusting columns 7, cylindrical contact protrusions 12 are arranged at both ends of the upper surface of the linkage seats 5, the upper end of the contact protrusions 12 is inserted into the limit grooves 6, and the positioning grooves 10 are arranged such that, when limiting the position of the adjusting columns 7, the end of the limit rods 8 located in the limit grooves 6 is limited by the adjusting holes 9, and the end of the limit rods 8 located outside the support plates 1 is limited by the positioning grooves 10, thereby effectively improving the stability of the limit rods 8 during use by limiting both ends of the limit rods 8, and the compression springs 11 are arranged such that, when limiting the linkage seats 5, the adjusting columns 7 restrict the linkage seats 5 through the compression springs 11, thereby reducing the impact force generated when the adjusting columns 7 limit the height of the swing, and reducing the discomfort of the person swinging.

[0029] The traction rope 4 passes through the inside of the limiting ring 13, and the inner ring surface of the limiting ring 13 is provided with a plurality of matched rolling balls 14 corresponding to the traction rope 4. The limiting ring 13 and the rolling balls 14 are arranged to drive the rolling balls 14 to roll when the traction rope 4 moves, that is, the traction rope 4 is in rolling contact with the inner wall of the mounting cavity under the action of the rolling balls 14, thereby effectively reducing the wear of the traction rope 4 and prolonging the service life of the traction rope 4. The upper end of the support plate 1 is jointly provided with a shielding cover 15, the shielding cover 15 covers the outside of the linkage shaft 2, and the shielding cover 15 is arranged to prevent rainwater from directly contacting the linkage shaft 2, thereby reducing the erosion of rainwater on the linkage shaft 2, and further prolonging the service life of the device. The lower end of the linkage plate 3 is provided with an adjusting plate 16, the junction of the adjusting plate 16 and the linkage plate 3 is provided with a plurality of insertion holes, and the insertion holes are provided with a latch. The adjusting plate 16 is installed at both ends of the swing seat, and the adjusting plate 16 is arranged to facilitate the adjustment of the height of the swing seat, that is, to facilitate the use of children or adults of different heights, thereby improving the adaptability of the device.

[0030] Principle and advantages: in the use process, when the swing seat is in a stationary state, the linkage seat 5 is at the bottom of the mounting cavity, and when the swing seat is in motion, that is, when a child rides the swing seat to swing, the swing seat drives the linkage plate 3 to rotate the linkage shaft 2, and because the end of the linkage shaft 2 is connected with the traction rope 4, the linkage shaft 2 reciprocally winds and unwinds the traction rope 4 when rotating, and the traction rope 4 drives the linkage seat 5 to move up when winding, and the linkage seat 5 is reset under the action of gravity when the traction rope 4 is unwound. Because the adjusting column 7 is arranged above the linkage seat 5, the distance of the linkage seat 5 moving up is restricted by the adjusting column 7, that is, when the linkage seat 5 touches the adjusting column 7, the linkage seat 5 cannot continue to move up, and the linkage seat 5 cannot continue to move up, which limits the linkage shaft 2 through the traction rope 4, that is, the linkage shaft 2 cannot continue to rotate at this time, and this is the highest point of the swing seat.

[0031] In summary, the height of the swing seat is restricted by the adjusting column 7 when it swings, so that personnel only need to adjust the height of the adjusting column 7 through the limiting rod 8 to control the swing height of the swing seat, that is, personnel only need to stand on the ground to realize the effect of adjusting the swing height, that is, compared with the traditional scheme, the scheme can effectively and conveniently adjust the swing height according to the specific use requirement, and through the arrangement of the compression spring 11, when the linkage seat 5 hits the adjusting column 7, the compression spring 11 is first used to reduce the impact force when the two collide, thereby improving the comfort of personnel riding the swing seat.

[0032] It needs to be further explained that the positioning groove 10 is arranged, so that when the limiting rod 8 limits the position of the adjusting column 7, the end of the limiting rod 8 inside the limiting groove 6 is limited by the adjusting hole 9, and the end of the limiting rod 8 outside the supporting plate 1 is limited by the positioning groove 10, thereby effectively improving the stability of the limiting rod 8 during use by limiting both ends of the limiting rod 8. The arrangement of the compression spring 11 makes the adjusting column 7 limit the linkage seat 5, and the adjusting column 7 restricts the linkage seat 5 through the compression spring 11, so that the impact force generated when the adjusting column 7 limits the height of the swing swing is smaller, thereby reducing the discomfort caused to the swing person; the arrangement of the limiting ring 13 and the ball 14 makes the traction rope 4 move and drive the ball 14 to roll, that is, under the action of the ball 14, the traction rope 4 and the inner wall of the installation cavity are in rolling contact, thereby effectively reducing the wear of the traction rope 4, that is, prolonging the service life of the traction rope 4; the arrangement of the shielding cover 15 makes the external rainwater unable to directly contact the linkage shaft 2, thereby reducing the erosion of the rainwater to the linkage shaft 2, thereby further prolonging the service life of the device; the arrangement of the adjusting plate 16 facilitates the adjustment of the height of the swing seat by the person, that is, it is convenient for children or adults of different heights to use, thereby improving the adaptability of the device.

[0033] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
