Description
Technical Field
[0001] The invention relates to the field of fitness and entertainment equipment, in particular to a double seesaw with a limiter. Background Art
[0002] At present, the double seesaw is a classic outdoor amusement facility designed for two people to play at the same time. This facility consists of a long board, fixed by a fulcrum in the middle, and the two ends can rise and fall. When two people sit on the two ends of the seesaw, they can make the seesaw move dynamically by adjusting their weight distribution and force, forming an ups and downs effect, bringing endless fun and laughter.
[0003] The existing two-person seesaw includes a support seat and a balance bar, and the middle position of the balance bar is rotatably mounted on the bearing seat; so that when two people sit on both ends of the balance bar respectively, the rotation limit of the balance bar is that one end of the balance bar abuts against the ground.
[0004] With respect to the above-mentioned related technologies, when two children sit on the two sides of the balance bar to play, the balance bar will hit the ground and stop rotating, which is very dangerous and not conducive to the children's play. Summary of the invention
[0005] In order to improve the safety of the seesaw, the present application provides a double seesaw with a limiter.
[0006] The present application provides a double seesaw with a limit position, which adopts the following technical solution:
[0007] A double seesaw with limits, comprising a support seat and a balance bar, wherein the balance bar is provided with a connecting tube, and the connecting tube is rotatably mounted on the support seat via a rotating shaft, and limit plates are arranged in the connecting tube at circumferential intervals along the rotating shaft, and limit spaces are formed between adjacent limit plates; limit rods are arranged in the connecting tube and corresponding to each of the limit spaces for sliding movement, and both ends of the limit rods are mounted on the support seat; the sliding angle of the limit rod in the limit space is smaller than the angle of the balance bar when it rotates and abuts against the ground.
[0008] By adopting the above technical solution, when two people sit at the two ends of the balance bar respectively, the balance bar will swing due to their own gravity. In this process, the limit rod slides in the limit space, and the sliding angle of the limit rod in the limit space is limited by the position of the limit plate. Moreover, the sliding angle of the limit rod in the limit space is smaller than the angle when the balance bar rotates and abuts against the ground. Therefore, when the balance bar rotates to the extreme angle, there is still a distance between the end of the balance bar and the ground, and there will be no impact vibration, which improves the safety of using the seesaw.
[0009] Preferably, the connecting tube is provided with a plurality of pairs of buffer blocks in each of the limiting spaces, and the two buffer blocks of the same pair are located on both sides of the corresponding limiting rod.
[0010] By adopting the above technical solution, when the balance bar swings to the extreme position, the limit rod hits the buffer block. Through the buffering effect of the buffer block, the vibration intensity of the balance bar is reduced, thereby improving the use comfort.
[0011] Preferably, a groove matching the limiting rod is formed on a side of the buffer block facing the limiting rod.
[0012] By adopting the above technical solution, the contact between the limit rod and the buffer block is more complete, thereby improving the buffering effect.
[0013] Preferably, the sliding angle of the limiting rod in the limiting space is 10°-20°.
[0014] By adopting the technical solution, the swing angle when two people play on the balance pole will not be too large to be dangerous, nor will it reduce the playability due to too small an angle.
[0015] Preferably, a pair of mounting plates are installed on the support seat, the rotating shaft is fixedly installed between the two mounting plates, and the rotating shaft is coaxially passed through the connecting tube; the rotating shaft sleeve is provided with a plurality of bearings, and the outer rings of the bearings are fixedly connected to the connecting tube.
[0016] By adopting the above technical solution, the connecting tube is installed between the two mounting plates, achieving a limiting effect, and this installation method has high stability.
[0017] Preferably, both ends of the rotating shaft extend out of the mounting plate, and the part of the rotating shaft extending out of the mounting plate is provided with a locking groove along the circumferential direction. A locking ring is sleeved on the rotating shaft corresponding to the locking groove, and the outer ring of the locking ring is outside the locking groove and is tightly pressed against the mounting plate; both ends of the rotating shaft are threadedly installed with locking bolts, and the head of the locking bolt is pressed against the rotating shaft.
[0018] By adopting the above technical solution, after the seesaw has been used for a period of time, looseness may occur between the rotating shaft and the connecting plate. At this time, the locking bolt can be tightened to increase the friction between the locking ring and the mounting plate, thereby improving the installation stability.
[0019] Preferably, a protective cover is provided on a side of the mounting plate away from the connecting tube and corresponding to the position of the rotating shaft, a maintenance opening is opened on the protective cover corresponding to the locking bolt, and a bolt cover is clamped on the protective cover corresponding to the maintenance opening.
[0020] By adopting the above technical solution, in order to protect the locking bolt, a protective cover is set at the corresponding position; when the seesaw needs to be maintained, the bolt cover is first opened and the locking bolt is adjusted through the maintenance port; the structure is simple and easy to use.
[0021] Preferably, the protective cover is provided with a limiting ring extending circumferentially at the maintenance opening, and the inner ring of the limiting ring is clamped at a position between the head of the locking bolt and the rotating shaft.
[0022] By adopting the above technical solution, the structure can synchronously fix the protective cover through the locking bolts, which is easy to install and highly practical.
[0023] Preferably, cushion plates are installed on both ends of the balance bar.
[0024] By adopting the above technical solution, providing a seat cushion can enhance the user's experience and improve comfort.
[0025] Preferably, a grip ring is installed on the balance bar at a position on one side where the two cushion plates are close to each other.
[0026] By adopting the above technical solution, a point of force can be provided to the user, thereby further improving the safety of playing.
[0027] In summary, the present application includes at least one of the following beneficial technical effects:
[0028] 1. When two people sit at the two ends of the balance bar, the balance bar swings due to their own gravity. During this process, the limit bar slides in the limit space, and the position of the limit plate limits the sliding angle of the limit bar in the limit space. The sliding angle of the limit bar in the limit space is smaller than the angle when the balance bar rotates and abuts against the ground. Therefore, when the balance bar rotates to the limit angle, there is still a distance between the end of the balance bar and the ground, and there will be no impact vibration, which improves the safety of using the seesaw.
[0029] 2. When the balance bar swings to the limit position, the limit bar hits the buffer block. The buffering effect of the buffer block reduces the vibration intensity of the balance bar and improves the comfort of use;
[0030] 3. The installation tightness of the shaft can be adjusted and the protective cover can be fixed synchronously by tightening the bolt, which is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
