Description

Technical Field

[0001] The utility model relates to the technical field of amusement equipment, and particularly to a children's amusement seesaw. Background Art

[0002] The seesaw utilizes the lever principle. Due to its simple structure and strong entertainment value, it has been popularized as an amusement project in urban and rural communities. At the same time, the seesaw has always occupied an important position in children's amusement projects. The existing seesaw includes a seesaw board, two support rods, and a crossbar connecting the two support rods. The seesaw board is connected to the crossbar by a lever. In actual operation, one person sits on one side of the seesaw board, and using the lever principle, when one person goes up, the other person goes down.

[0003] However, since the majority of the users of the seesaw are children and their awareness of danger is insufficient, many children often try to kick the ground with their legs to make themselves rise higher or suddenly exert force downward to make the other person rise higher in pursuit of excitement, but this is very dangerous. When the seesaw rises, it will generate an upward throwing force on the children, and at the same time, due to the inclination, it will also generate a forward tilting force.

[0004] In order to address the above problems, there is an urgent need for a children's amusement seesaw with safety features. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a children's amusement seesaw to solve the problems raised in the above background art.

[0006] To achieve the above purpose, a children's amusement seesaw is provided, which includes a seesaw board and a triangular support base. The seesaw board is installed on the triangular support base through a rotating shaft. A bearing cooperating with the rotating shaft is arranged on the triangular support base. A speed limiting component for restricting the rotation speed of the seesaw board is arranged on the part of the rotating shaft near both ends;

[0007] A backrest and armrests are further arranged at the end of the seesaw board, and a rotatable guardrail is arranged on the backrest;

[0008] The seesaw board is composed of three parts, including a middle part connected to the triangular support base and movable parts movably installed at both ends of the middle part. The movable parts and the middle part are connected by an adjusting structure;

[0009] The adjusting structure can adjust the position of the movable part to change the overall length of the seesaw board.

[0010] Further, the speed limiting component includes a protrusion, a groove, a spring, a telescopic tube and a brake pad. The protrusion is in a circular tubular structure and is provided on the triangular support base. The groove is opened on the surface of the rotating shaft and is arranged in a ring shape. One ends of the telescopic tube and the spring are both installed in the groove, and the other ends of the telescopic tube and the spring are both fixedly connected to the brake pad. The brake pad can contact the inner wall of the protrusion and generate friction under the action of centrifugal force to overcome the tension of the spring.

[0011] Further, the protrusion and the rotating shaft are coaxially arranged. The telescopic tube is composed of two coaxial tubes with different diameters, and the telescopic tube is used to limit the displacement of the brake pad only along the axis direction of the telescopic tube.

[0012] Further, the adjusting structure includes a fixing hole provided on the middle part and a plurality of limiting holes provided on the movable part, and further includes a limiting pin that can be inserted into the fixing hole and the limiting holes.

[0013] Further, the backrest and the armrest are both provided on the movable part. The armrest is located in front of the backrest, and the rotating shaft is provided on the middle part.

[0014] Further, the guardrail includes two lever bars that can rotate around the backrest and a "U"-shaped waist bar. The tops of both ends of the waist bar are fixedly connected to the lever bars.

[0015] Further, a buffer pad is further provided at the bottom of the movable part.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. In the riding area for children, that is, at both ends of the seesaw, there are a backrest and an armrest, which respectively protect the children in the forward or backward leaning state. Moreover, the guardrail can restrict the shoulders and waists of the children to prevent the children from being jolted out or falling forward. As a rotatable component, the guardrail can also be easily lifted.

[0018] 2. During the process of the seesaw quickly and repeatedly tilting up and down, the rotation speed of its rotating shaft will also increase. The centrifugal force generated by the brake pad during rotation then overcomes the tension of the spring to generate friction with the inner wall of the protrusion for braking, thereby controlling the speed of the seesaw and improving safety.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Those skilled in the art of the present technology can understand that unless specifically stated otherwise, the singular forms "a", "an" and "the" used herein may also include the plural forms. It should be further understood that the term "comprising" used in the description of the present utility model 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 their groups.

[0027] Please refer to Figures 1-4 As shown, a children's amusement seesaw is provided, including a teeter board 1 and a triangular support base 2. The teeter board 1 is installed on the triangular support base 2 through a rotating shaft 3. A bearing cooperating with the rotating shaft 3 is provided on the triangular support base 2. A speed limiting assembly 5 for restricting the rotation speed of the teeter board 1 is provided on the part of the rotating shaft 3 near both ends. The principle of the speed limiting assembly 5 is to use the centrifugal force generated during the rotation of the teeter board 1 to make the internal brake pad 505 overcome the pulling force of the spring 503 and generate friction with the inner wall of the protruding part 501 for braking. Under normal conditions, the brake pad 505 is affected by the pulling force of the spring 503 and does not contact the inner wall of the protruding part 501, so it can play normally;

[0028] A backrest 6 and an armrest 7 are further provided at the end of the teeter board 1. A rotatable guardrail 8 is provided on the backrest 6;

[0029] The seesaw 1 consists of three parts, including an intermediate part 101 connected to the triangular support base 2 and movable parts 102 movably installed at both ends of the intermediate part 101. The movable parts 102 and the intermediate part 101 are connected by an adjustment structure 9. The intermediate part 101 is a hollow frame structure;

[0030] The adjustment structure 9 can adjust the position of the movable part 102 to change the overall length of the seesaw 1. By adjusting the lengths of both ends of the seesaw 1, children with a large difference in weight can play together, and it will not happen that a child with a larger weight presses down the seesaw 1 and cannot get up.

[0031] Please refer to Figure 1 and Figure 3 as shown:

[0032] The protruding part 501 and the rotating shaft 3 are coaxially arranged. The telescopic tube 504 is composed of two different-diameter tubes arranged coaxially. The telescopic tube 504 is used to limit the displacement of the brake pad 505 only along the axis direction of the telescopic tube 504;

[0033] When the brake pad 505 contacts the protruding part 501 and generates friction, the brake pad 505 also receives the same frictional force. The direction of the frictional force is tangent to the rotating shaft 3. This force will cause the spring 503 connected to the brake pad 505 to bend and deform. The function of the telescopic tube 504 is to enable the brake pad 505 to offset this force so that the spring 503 will not bend and deform. After adding the telescopic tube 504, this force acts on the telescopic tube 504, and as a tubular structure, the telescopic tube 504 has a much greater anti-deformation ability than the spring 503.

[0034] As Figure 2 and 3 shown:

[0035] The speed limiting component 5 includes a protruding part 501, a groove 502, a spring 503, a telescopic tube 504 and a brake pad 505. The protruding part 501 is in a circular tubular structure and is arranged on the triangular support base 2. The groove 502 is opened on the surface of the rotating shaft 3 and is arranged in a ring shape. One end of the telescopic tube 504 and the spring 503 are both installed in the groove 502. The other ends of the telescopic tube 504 and the spring 503 are both fixedly connected to the brake pad 505. The brake pad 505 can contact the inner wall of the protruding part 501 and generate friction under the action of centrifugal force to overcome the pulling force of the spring 503.

[0036] As Figure 4 shown:

[0037] The adjusting structure 9 includes a fixing hole 901 provided on the middle part 101 and a plurality of limiting holes 902 provided on the movable part 102, and further includes a limiting pin 903 that can be inserted into the fixing hole 901 and the limiting holes 902; the limiting pin 903 connects different limiting holes 902 with the fixing hole 901, so as to control the depth of insertion of the movable part 102 into the middle part 101, thereby changing the lengths of both ends of the seesaw 1.

[0038] The backrest 6 and the armrest 7 are both provided on the movable part 102, the armrest 7 is located in front of the backrest 6, and the rotating shaft 3 is provided on the middle part 101.

[0039] As Figure 1 shown:

[0040] The guardrail 8 includes two blocking rods that can rotate around the backrest 6 and a "U"-shaped waist rod. The tops of both ends of the waist rod are fixedly connected to the blocking rods. A buffer pad is also provided at the bottom of the movable part 102; in the actual use process, the blocking rods can fix the shoulders of children, and the waist rod can fix the waists of children.

[0041] Working principle:

[0042] A children's amusement seesaw described in the present utility model is provided with a backrest 6 and an armrest 7 at both ends of the seesaw 1, that is, in the riding area of children, which respectively protect children in the forward or backward leaning states; moreover, a guardrail 8 is also provided on the backrest 6. After the guardrail 8 is pressed down, the guardrail 8 can limit the shoulders and waists of children to prevent children from being jolted out or falling forward. As a rotatable component, the guardrail 8 can also be easily lifted.

[0043] During the process of the seesaw quickly and repeatedly tilting up and down, the rotation speed of its rotating shaft 3 will also increase. At this time, the centrifugal force obtained by the brake piece 505 through rotation can overcome the pulling force of the spring 503 on it; thus, the brake piece 505 will contact the inner wall of the protruding part 501 and generate frictional resistance. The increase in frictional resistance will cause the speed of the rotating shaft 3 to decrease, which also slows down the tilting up and down speed of the seesaw. After the speed slows down, it is not easy to generate a large impact force with the ground, and the seesaw will not generate too much throwing force on children. Therefore, it can better protect the amusement safety of children.

[0044] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
