Problems solved by technology

[0002] The seesaw is a toy that children will experience. It can exercise children's waist strength. The traditional seesaw has a simple structure, a single movement, and is not interesting enough. However, the carousel has a complex structure, high cost, and is difficult to popularize. It is mentioned in the patent document of the publication number 202876332U There is a rotatable seesaw with one degree of freedom, which uses multiple hinges to achieve the rotation effect. This R-2SSR-R space linkage mechanism increases the complexity of the equipment structure, making the installation of the equipment inconvenient, and the seesaw is constantly swinging. The speed of rotation will become faster and faster, which will cause safety hazards

Embodiment approach

[0020] As an improved specific embodiment, the brake mechanism 120 includes a disc 121, a caliper 122 and a connecting wire 123, the disc 121 is coaxially fixedly connected to the central shaft 3, and the caliper 122 is sleeved on the disc 121 Above, the caliper 122 is connected to the connecting wire 123, and the other end of the connecting wire 123 opposite to the caliper 122 is fixedly connected to the pedal 130. When the pedal 130 turns over and pulls the connecting wire 123, the connecting wire 123 pulls the caliper 122 to make the caliper 122 clamps the disc 121 to limit the horizontal rotation of the seesaw 2 .

[0021] Through the above technical solution, this embodiment uses the disc 121, the caliper 122 and the connecting wire 123 to build the brake mechanism 120, fix the disc 121 on the central shaft 3, and then put the caliper 122 on the central shaft 3, by connecting The wire 123 is fixed on the pedal 130, and the connecting wire 123 is pulled by turning over the...

Abstract

The invention discloses a seesaw. A seesaw body is hinged on a supporting pillar; the supporting pillar comprises a rotary head and a base, wherein the rotary head is connected to the base in a rotatable mode; a central shaft is fixedly connected to one end of the base, and relative to the other end of the base, a transmission shaft is rotatably connected to the central shaft; the transmission shaft is fixedly connected to the rotary head; the transmission shaft is rotatably connected to the central shaft by virtue of a second bearing; a fixed gear additionally sleeves the central shaft; a transmission gear sleeves the transmission shaft; a third bearing additionally sleeves the transmission shaft; an outer ring of the third bearing is embedded into the transmission gear; the transmissiongear is rotatably connected to the transmission shaft by virtue of the third bearing, and the transmission gear is meshed with the fixed gear; the seesaw body is hinged on the rotary head in a mode ofbeing capable of turning up and down; a ratchet wheel is fixedly connected to one end face of the transmission gear; a pawl base is hinged on the seesaw body; a plurality of pawls are hinged on the pawl base, so that the ratchet wheel is driven to rotate; and the rotary head and the central shaft are driven to do concentric rotation.

Description

technical field [0001] The invention relates to a teaching toy, in particular to a seesaw. Background technique [0002] The seesaw is a toy that children will experience. It can exercise children's waist strength. The traditional seesaw has a simple structure, a single movement, and is not interesting enough. However, the carousel has a complex structure, high cost, and is difficult to popularize. It is mentioned in the patent document of the publication number 202876332U There is a rotatable seesaw with one degree of freedom, which uses multiple hinges to achieve the rotation effect. This R-2SSR-R space linkage mechanism increases the complexity of the equipment structure, making the installation of the equipment inconvenient, and the seesaw is constantly swinging. The speed of rotation will be faster and faster, which will cause safety hazards. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to prov...
