Description

Technical Field

[0001] The present invention relates to the field of sports equipment, and particularly to a swing with an emergency stop function. Background Art

[0002] In the existing Chinese patent database, a patent named swing is disclosed. The application number of this patent is: 201120195603.3, the application date is June 8, 2011, the authorized announcement number is CN 202136794 U, and the authorized announcement date is February 8, 2012. Its structure includes: a swing frame and a swing seat board connected to the swing frame. The swing seat board includes ropes and a seat board. The characteristic is that: an adjusting device for adjusting the height of the seat board is provided between the ropes and the swing frame. Its disadvantage is that: when people need to get off the swing urgently while playing on the swing, due to the continuous swinging of the swing, people can only get off when the swing is stationary or almost stationary. Therefore, this swing is not convenient to use. Summary of the Invention

[0003] The purpose of the present invention is to provide a swing that can quickly stop the seat board in view of the deficiencies of the existing technology.

[0004] In order to achieve the above object of the invention, the technical solution adopted by the present invention is as follows:

[0005] A swing with an emergency stop function includes two vertically arranged upright rods. A horizontal cross bar is fixedly connected between the upper ends of the two upright rods. Two hanging ropes are connected to the cross bar. A seat board is connected between the lower ends of the two ropes. A tensioning device close to the cross bar is provided outside between the rope and the adjacent upright rod. The tensioning device is tied to the cross bar through a release device, and the lower end of the release device hangs on the side of the seat board.

[0006] When the present invention works, first, the user sits on the seat board of the swing and moves. When the user needs to get off the seat board, the user pulls the release device on the side of the seat board. After the release device falls off, the tensioning device falls due to its own weight. During the falling process, the swinging angle of the rope gradually decreases, the seat board is in a static state, and the user gets off. Compared with the existing technology, the beneficial effect of the present invention is that: due to the cooperation of the tensioning device and the release device, the swinging seat board can be effectively and gently stopped, which is convenient for the user to get off as soon as possible. At the same time, the device has a simple structure, is easy to operate, and has a low cost.

[0007] In order to quickly and effectively stop the rope, the tensioning device is an elliptical ring made of rigid material or elastic material, and the rope and the adjacent upright rod pass through the elliptical ring.

[0008] In order to quickly and effectively stop the rope, the tensioning device is a sliding ring respectively sleeved on the rope and the upright rod, and a tension spring is connected between the two sliding rings.

[0009] For the convenience of timely release of the tensioning device, the release device is a pull rope, and one end of the pull rope is provided with a slipknot rope loop for fixing the tensioning device on the cross bar.

[0010] For the convenience of timely release of the tensioning device, the release device is a clip or a hook for connecting the tensioning device to the cross bar, and a thin rope fixedly connected to the tensioning device, and the thin rope is used for pulling the tensioning device.

[0011] For the convenience of the tensioning device to return to the initial position, a first pulley is provided on the cross bar above the tensioning device, second pulleys are connected to both ends of the cross bar, a hand wheel is connected to the vertical rod, a steel wire is connected to the hand wheel, and the other end of the steel wire passes through the second pulley and the first pulley and is connected to the clip.

[0012] Furthermore, the vertical rod and the cross bar are welded together. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present invention will be further described below in conjunction with specific embodiments:

[0018] Embodiment 1

[0019] As Figure 1 described, it is an emergency stop swing, including two vertically arranged vertical rods 1, a horizontal cross bar 2 is fixedly connected between the upper ends of the two vertical rods 1, two hanging ropes 3 are connected to the cross bar 2, a seat board 4 is connected between the lower ends of the two ropes 3, an oval ring 501 close to the cross bar 2 is arranged outside between the rope 3 and the adjacent vertical rod 1, the oval ring 501 is tied to the cross bar 2 by a slipknot rope loop 602 at the upper end of the pull rope 601, and the lower end of the pull rope 601 hangs on the side of the seat board 4.

[0020] When in use, first the user sits on the seat board 4 of the swing and moves. When the user needs to get off the seat board 4, the user pulls the pull rope 601 on the side of the seat board 4. After the pull rope 601 comes off, the oval ring 501 falls due to its own weight. During the falling process, the swinging angle of the rope 3 gradually decreases, the seat board 4 is stationary, and the user gets off.

[0021] Embodiment 2

[0022] The difference from Embodiment 1 is that as Figure 2 described, slip rings 502 are sleeved on each rope 3 and each vertical rod 1. A tension spring 503 is fixedly connected to the slip ring 502 between the rope 3 and the adjacent vertical rod 1. A thin rope 604 is fixedly connected to the tension spring 503. The lower end of the thin rope 604 hangs on the side of the seat board 4. A clip 603 for clamping the tension spring 503 is installed on the cross bar 2 between the rope 3 and the adjacent vertical rod 1.

[0023] When in use, first the user sits on the seat board 4 of the swing and moves. When the user needs to get off the seat board 4, the user pulls the thin rope 604 on the side of the seat board 4. The tension spring 503 falls. During the falling process, the swinging angle of the rope 3 gradually decreases, the seat board 4 is stationary, and the user gets off.

[0024] Embodiment 3

[0025] The difference from Embodiment 1 is that as Figure 3 described, slip rings 502 are sleeved on each rope 3 and each vertical rod 1. A tension spring 503 is fixedly connected to the slip ring 502 between the rope 3 and the adjacent vertical rod 1. A thin rope 604 is fixedly connected to the tension spring 503. The lower end of the thin rope 604 hangs on the side of the seat board 4. A first pulley 701 is provided on the cross bar 2 above the tension spring 503. Second pulleys 702 are connected to both ends of the cross bar 2. A hand wheel 703 is connected to the vertical rod 1. A steel wire 704 is connected to the hand wheel 703. The other end of the steel wire 704 passes through the second pulley 702 and the first pulley 701 and is connected to the clip 603. The clip 603 is used to clamp the tension spring 503 so that the tension spring 503 is pressed against the cross bar 2.

[0026] When in use, first the user sits on the seat board 4 of the swing and moves. When the user needs to get off the seat board 4, the user pulls the thin rope 604 on the side of the seat board 4. The tension spring 503 falls. During the falling process, the swinging angle of the rope 3 gradually decreases, the seat board 4 is stationary, and the user gets off. After the user gets off, the user rotates the hand wheel 703 to lower the clip 603 connected to the steel wire 704, then uses the clip 603 to clamp the tension spring 503, rotates the hand wheel 703, and when the tension spring 503 rises and is pressed tightly against the cross bar 2, stops rotating the hand wheel 703.

[0027] The present invention is not limited to the above embodiments. Based on the technical solutions disclosed in the present invention, those skilled in the art can make some substitutions and deformations to some of the technical features without creative labor according to the disclosed technical content, and these substitutions and deformations are all within the protection scope of the present invention.
