Description

Technical Field

[0001] This utility model relates to the field of outdoor children's playground toys, specifically to an outdoor children's playground swing device. Background Technology

[0002] With the growing development of the swing amusement industry, product functionality is no longer a singular pursuit. Users are constantly seeking safer and more fun product experiences. Steel wire rope products are increasingly used in the swing industry, for example, many outdoor swings have been set up in public entertainment venues such as large shopping malls, parks, and residential communities for children to play on.

[0003] However, when people play on a swing, someone needs to push the person sitting on the swing from behind. Sometimes, when they are having a great time, the person behind will exert a lot of force, which makes the swing swing more widely. When the swing swings too much, the person sitting on the swing is also prone to being thrown off by centrifugal force, causing unpredictable consequences.

[0004] To address the aforementioned problems, there is an urgent need for an outdoor children's playground swing device. Summary of the Invention

[0005] The purpose of this invention is to provide an outdoor children's playground swing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, an outdoor children's play swing device is provided, including a support frame and a suspension beam. The support frame has an "A" shaped structure, and the suspension beam is installed between two support frames. Rotatable sleeves are sleeved at both ends of the suspension beam, and iron chains are fixedly installed on the outside of the sleeves. A seat is fixedly installed at the end of the iron chains. The suspension beam is also equipped with an angle limiting mechanism, which includes a torsion spring, a limiting tube, a limiting groove, and a trigger rod. The two ends of the torsion spring are locked in the limiting grooves on the inner wall of the limiting tube. The limiting tube is fixedly sleeved on the cantilever beam. The trigger rod is fixedly installed at one end of the sleeve. When the sleeve rotates, the trigger rod can contact and squeeze the torsion spring. This angle limiting mechanism can be used to block the angle of rotation of the sleeve on the surface of the cantilever beam. When the angle of rotation of the sleeve is too large, the trigger rod will contact the torsion spring and apply torque to the torsion spring, thus achieving the effect of limiting the rotation angle of the sleeve. Its external manifestation is that when the swing reaches the highest point, there is a resistance to prevent the swing from swinging to a certain height, ensuring that the swing's angle of movement is less than 180°.

[0007] Furthermore, two limiting grooves are provided in total, and the two limiting grooves are staggered one after the other. The opening position and shape of the limiting grooves are designed based on the torsion spring. Since the torsion spring is sleeved on the suspension beam, the limiting grooves can prevent the other end from rotating when one end of the torsion spring is subjected to force.

[0008] Furthermore, the trigger rod is fixedly installed near the end of the torsion spring, and there are at least two trigger rods. The two trigger rods are in movable contact with one end of the torsion spring, and the lengths of the two trigger rods are not equal.

[0009] Furthermore, the torsion spring is sleeved on the suspension beam, the inner diameter of the limiting tube is larger than the outer diameter of the suspension beam, and the end of the limiting tube near the sleeve is an open structure, through which the trigger rod on the sleeve can be inserted into the interior of the limiting tube.

[0010] Furthermore, in its natural state, the two trigger rods are positioned in the lower half of the sleeve.

[0011] Furthermore, both ends of the cantilever beam are provided with grooves for installing sleeves. These grooves can restrict the movement of the sleeves, ensuring that the sleeves can rotate without lateral displacement.

[0012] Furthermore, the end of the chain forks to form a three-pronged structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: An angle limiting mechanism is used to reduce the swing amplitude. When the swing reaches the set top, the trigger rod will contact the torsion spring and apply torque to the torsion spring. The torsion spring will use its own elastic potential energy to counteract this excess force, thereby forcing the swing to be unable to rotate to a larger angle, thus achieving the protection of children. The torsion spring slowly counteracts the impact of the trigger lever, preventing the swing from stopping immediately when it reaches its highest point, thus reducing the effects of inertia.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” and “described” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this specification means the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0018] Please see Figures 1-4 As shown, an outdoor children's playground swing device is provided, including a support frame 1 and a suspension beam 2. The support frame 1 has an "A" shaped structure. The suspension beam 2 is installed between two support frames 1. Rotatable sleeves 3 are sleeved at both ends of the suspension beam 2. Iron chains 4 are fixedly installed on the outside of the sleeves 3. A seat 5 is fixedly installed at the end of the iron chains 4. In practice, the seat 5 can be designed as a backrest or any existing conventional technology cushion as needed. The suspension beam 2 is also provided with an angle limiting mechanism 6, which includes a torsion spring 601, a limiting tube 602, a limiting groove 603 and a trigger rod 604. The two ends of the torsion spring 601 are locked in the limiting groove 603 on the inner wall of the limiting tube 602. The limiting tube 602 is fixedly sleeved on the suspension beam 2. The trigger rod 604 is fixedly installed at one end of the sleeve 3. When the sleeve 3 rotates, the trigger rod 604 can contact and squeeze the torsion spring 601. The angle limiting mechanism 6 can be used to block the angle of rotation of the sleeve 3 on the surface of the cantilever beam 2. When the angle of rotation of the sleeve 3 is too large, the trigger rod 604 will contact the torsion spring 601 and apply torque to the torsion spring 601. This achieves the effect of limiting the rotation angle of the sleeve 3. Its external manifestation is that when the swing reaches the highest point, there is a resistance to prevent the swing from swinging to a certain height, ensuring that the swing's angle of movement is less than 180°. At the same time, it should be noted that when the swing reaches the highest point, the torsion spring 601 will not immediately stop the sleeve 3 from rotating. Instead, there is a buffering process, using the torsion spring to counteract the kinetic energy of the swing.

[0019] To fix the torsion spring 601, two limiting grooves 603 are provided. The two limiting grooves 603 are staggered one after the other. The opening position and shape of the limiting grooves 603 are designed based on the torsion spring 601. Since the torsion spring 601 is sleeved on the suspension beam 2, by setting the limiting grooves 603, when one end of the torsion spring 601 is subjected to force, the other end can be blocked by the limiting grooves 603 to prevent rotational displacement. The trigger rod 604 is fixedly installed at the end near the torsion spring 601. There are at least two trigger rods 604. The two trigger rods 604 are in movable contact with one end of the torsion spring 601. Since the two ends of the torsion spring 601 are set one in front of the other, the lengths of the two trigger rods 604 are not equal.

[0020] Please refer to Figures 1-4 As shown: The torsion spring 601 is sleeved on the suspension beam 2. The inner diameter of the limiting tube 602 is larger than the outer diameter of the suspension beam 2. The end of the limiting tube 602 near the sleeve 3 is an open structure. The trigger rod 604 on the sleeve 3 can be inserted into the interior of the limiting tube 602 through the opening. Combination Figure 2 , Figure 3 and Figure 4 As shown, when the torsion spring 601 is fixed inside the limiting tube 602, since the two ends of the torsion spring 601 are stuck by the limiting groove 603, even if the trigger rod 604 contacts one end of the torsion spring 601, the torsion spring 601 will not rotate with the sleeve 3. However, at the same time, the limiting groove 603 will not restrict the two ends of the torsion spring 601 from moving towards the middle. from Figure 4 As can be seen, in its natural state, the two trigger rods 604 are located in the lower half of the sleeve 3, and as the swing swings, the trigger rods 604 will contact the end of the torsion spring 601. Both ends of the cantilever beam 2 are provided with grooves for installing the sleeve 3. These grooves can restrict the movement of the sleeve 3, ensuring that the sleeve 3 can rotate without lateral displacement.

[0021] Work process: During play, as the swing swings, when it reaches a certain angle, the trigger rod 604 will contact the end of the torsion spring 601. Since the torsion spring 601 is fixed by the limiting groove 603, the torsion spring 601 will not rotate with the sleeve 3. Instead, the trigger rod 604 applies torque to the torsion spring 601. At this time, the torsion spring 601 overcomes this high-speed impact force, forcing the swing to stop slowly. After the swing stops, it swings in the direction of gravity again. During this process, even if the swing swings too much, the angle limiting mechanism 6 can be used to force the swing to stop, thus preventing the dangerous situation of the player flying off the seat 5.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
