Description

Technical Field

[0001] The utility model relates to the technical field of swing protection, in particular to a swing protection frame structure for preventing children from falling off for amusement. Background Art

[0002] At present, a swing for children's amusement generally includes a frame, a hanging rope and a seat installed on the frame, and lacks a corresponding protective structure. Therefore, some technical solutions for swing protection have also appeared in the prior art. For example, a corrosion-resistant and rust-resistant swing recorded in Publication No. CN219681653U includes a crossbar, a No. 1 bracket is fixedly provided on both sides of the lower end surface of the crossbar, a switch seat is fixedly provided at the front end of one of the two No. 1 brackets, a No. 1 switch is fixedly provided at the upper front end of the switch seat, a No. 2 switch is fixedly provided at the lower front end of the switch seat, two No. 2 brackets are fixedly provided on both sides of the upper end surface of the crossbar, solar panels are fixedly provided on the upper end surfaces of the two No. 2 brackets, and a light tube is fixedly provided on the lower end surface of the solar panel;

[0003] The above device is provided with a safety belt to improve the safety of the swing seat and prevent the user from falling. The height of the swing can also be adjusted according to the height of the user, and the swing amplitude can also be changed according to the angle of the swing rope, so the range of users is expanded. However, the end of the safety belt is fixed at the user's crotch position, which is relatively fragile. Fixing the end there poses certain safety hazards. In addition, for a swing for two people with seats set up face to face, it is necessary to hold the swing when sitting on it to prevent the swing from shaking, which makes it inconvenient to get on the swing.
