Description

Technical Field

[0001] The utility model relates to the technical field of children's entertainment equipment, in particular to a seesaw. Background Art

[0002] Riding a seesaw is one of the favorite entertainment activities for children. The lengths of the two seesaws on the existing seesaws are equal, and the lengths on both sides are not adjustable. Therefore, when the weight of the users on both sides of the seesaw differs greatly, the seesaw is difficult to use normally. And the seesaw can only move by the people sitting on the two seesaws pushing down on the ground, which is laborious and lacks fun. A Chinese patent discloses a seesaw (its application number is CN201120035286.9), which includes a base and a seesaw hinged to the base, and outer plates are respectively installed on both sides of the seesaw, and a telescopic seesaw is installed in the outer plates. The seesaw is equipped with a telescopic seesaw that can adapt to people with large weight differences or when the number of people at both ends is unequal. Although the above patent solves the problem that the mass difference on both sides of the seesaw cannot save effort, it is inconvenient to adjust and requires moving the seat, and the telescopic structure is easily loosened during the use of the seesaw, shortening the service life. Utility Model Content

[0003] The utility model aims to solve the problems existing in the prior art and provides a seesaw, which is convenient for adjusting the center of gravity of the device and is suitable for use by people with large weight differences or when the number of people at both ends is unequal.

[0004] The utility model adopts the following technical solution to solve the technical problem: a seesaw, comprising a support and a plate body hinged to the support, seats are arranged at both ends of the plate body, armrests are arranged in front of the seats, a leveling device is fixedly installed on the plate body, the leveling device comprises a linear guide rail, a counterweight slider, a screw rod and a handwheel, the linear guide rail is fixedly installed on the plate body, bearing seats are arranged on the left and right sides of the linear guide rail, the screw rod is rotatably installed on the bearing seat, handwheels are fixedly installed at both ends of the screw rod, the handwheel is located below the armrest, the screw rod is threadedly connected to the counterweight slider, and the counterweight slider is slidably connected to the linear guide rail.

[0005] For further improvement, a tension spring is fixedly connected between the counterweight slider and the base.

[0006] To further improve, the seat is provided with a latex cushion, and the surface of the latex cushion is provided with a waterproof cloth.

[0007] For further improvement, a floor rod is hinged on the plate body below the seat, a rubber wheel is arranged at the lower end of the floor rod, and a spring shock absorber is hinged between the middle part of the floor rod and the plate body.

[0008] The beneficial effects of the utility model are as follows: 1. By setting a leveling device, including a linear guide rail, a counterweight slider, a screw rod and a hand wheel, the user can easily adjust the balance point of the seesaw. This design simplifies the adjustment process and improves the convenience of use. The design of the leveling device allows the seesaw to adapt to users of different weights, and balance is achieved by adjusting the position of the counterweight slider, making the seesaw more widely applicable.

[0009] 2. Avoid frequent seat movement and structural looseness, thus reducing wear on the seesaw structure and extending its service life. The design of the leveling device avoids the problem of structural looseness caused by telescoping. The threaded connection between the lead screw and the counterweight slider and the combination of the linear guide and the bearing seat ensure the structural stability and durability of the seesaw during the adjustment process.

DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings:

[0013] Referring to the accompanying drawings: a seesaw in this embodiment includes a support 1 and a plate body 2 hinged to the support 1, seats 8 are provided at both ends of the plate body 2, and armrests 9 are provided in front of the seats 8. A leveling device is fixedly installed on the plate body 2, and the leveling device includes a linear guide 3, a counterweight slider 4, a screw 5 and a handwheel 6. The linear guide 3 is fixedly installed on the plate body 2, and the installation orientations of the two are the same. Bearing seats 7 are set on the left and right sides of the linear guide 3, and the screw 5 is rotatably installed on the bearing seat 7. Handwheels 6 are fixedly installed at both ends of the screw 5, and the handwheel 6 is located below the armrest 9. The screw 5 is threadedly connected to the counterweight slider 4, and the counterweight slider 4 is provided with a threaded hole matching the screw 5, and the counterweight slider 4 is slidably connected to the linear guide 3.

[0014] How to use the seesaw:

[0015] Two users can sit on the seats at both ends of the board respectively. The handwheel is located under the armrest for easy operation. According to the weight and balance requirements of the user, the user rotates the handwheel to drive the screw 5 to rotate, and the screw 5 moves the position of the counterweight slider 5 on the linear guide to move it to the side of the user with light weight. By adjusting the position of the counterweight slider, the balance point of the seesaw can be changed so that the board remains horizontal when in use. After adjusting the counterweight slider, ensure that the seesaw can be balanced when there are people sitting on each seat. When both users are seated, they can make the seesaw swing up and down by moving their bodies up and down. During this process, the position of the counterweight slider remains unchanged to maintain the balance of the seesaw. After use, the user should get off the seat and check the seesaw again for any damage or abnormality. If necessary, the counterweight slider can be restored to its original position for the next use. In order to ensure the long-term and stable use of the seesaw, the leveling device should be inspected and maintained regularly to ensure the cleanliness and lubrication of components such as the screw, linear guide and bearing seat. Finally, stainless steel is used to prevent wear or corrosion caused by long-term use. Users can use the seesaw with a leveling device safely and conveniently to enjoy the fun of the game while ensuring safety during use.

[0016] A tension spring 10 is fixedly connected between the counterweight slider 4 and the base. When the counterweight slider 4 moves toward the light end, the tension spring 10 is stretched, and the elastic force generated can increase the torque on one side, improve the balancing efficiency, and shorten the travel of the counterweight slider 4. During use, the tension spring 10 can store energy, so that the seesaw can swing up and down for a longer time, and the user can save more effort.

[0017] The seat 8 is provided with a latex cushion 11, and a waterproof cloth is provided on the surface of the latex cushion 11. The latex cushion 11 is soft and elastic, and can improve the comfort of the user when using it, and protect the buttocks from being bruised.

[0018] A floor rod 13 is hinged on the board body 2 located below the seat 8, and a rubber wheel 14 is provided at the lower end of the floor rod 13. A spring shock absorber 12 is hinged between the middle part of the floor rod 13 and the board body 2. When the rubber wheel 14 touches the ground, it rolls, driving the floor rod 13 to rotate and compress the spring shock absorber 12 to achieve a shock-absorbing effect.

[0019] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
