Problems solved by technology

[0003] In addition to bearing the weight of the human body during use, the PU wheel may also cause greater pressure due to the jumping of the user. The bracket and the PU wheel tires will undergo various deformations. The pressure exceeding a certain limit will cause the PU wheel to produce irreversible deformation, affecting the normal operation of the PU wheel. use
[0004] However, if you simply consider the vibration reduction effect of the PU wheel and use a relatively soft PU wheel directly, the wear resistance of the PU wheel will be greatly reduced. Therefore, it is necessary to improve the wear resistance of the PU wheel on the premise of ensuring the wear resistance and service life of the PU wheel. Vibration reduction effect

Abstract

The invention provides a pu wheel. The pu wheel is characterized by comprising a mounting bracket and a wheel main body; the mounting bracket comprises an upper plate and a side plate; and a bearing hole is formed in the side plate, one end of the upper plate is connected to the upper end of the side plate, an upper spring, a pressing plate and a lower spring are sequentially connected to the interior of the upper plate from top to bottom, and the side plate comprises a clamping block, a clamping spring, a movable block and an ejector pin. The wheel main body comprises a hub and a tire; a hub hole is formed in the center of the hub; the tire comprises an outer wheel, side wheels and an inner wheel, the outer wheel is connected to the outer side of the inner wheel in a sleeving mode, the inner wheel is made of elastic plastic, the side wheels are matched with the outer wheel, the hub is located on the inner side of the inner wheel, a cavity is formed by the outer edges of the two side wheels, the inner wheel and the hub, and the hub is provided with an inflation inlet penetrating through the outer edge of the hub; and the inner wheel and the inflated cavity play a damping role, and the ejector pin abuts against the pu wheel to enable the pu wheel to stop rotating when the mounting bracket is overpressed.

Description

technical field [0001] The invention belongs to the field of pulleys, in particular to a pu pulley. Background technique [0002] PU wheels are rubber with a certain degree of elasticity. The main component is polyurethane. By changing the dosage and type of additives put into the PU production process, the PU wheels can have different elasticity and hardness. Usually, the supporting axle and bearing are connected with the corresponding device bracket, and the pu wheel directly touches the ground to rotate and drive the installation bracket and the equipment connected thereto to move. The pu wheel is often used in existing roller skates, skateboard shoes and scooters. [0003] In addition to bearing the weight of the human body during use, the PU wheel may also cause greater pressure due to the jumping of the user. The bracket and the PU wheel tires will undergo various deformations. The pressure exceeding a certain limit will cause the PU wheel to produce irreversible defor...
