[0013] Detailed ways: figure 1 Middle is the gravity brake wheel, the exploded diagram of the gravity brake wheel accessories of plastic parts. In the figure, the accessories of plastic and double-wheel gravity braking wheels are used as an example. The rollers (1) are pulled out from both sides of the horizontal shaft (2). The horizontal shaft (2) can be made of metal, and the horizontal shaft (2) is installed on the horizontal shaft. on the seat (3). The spring (4) can adjust the pre-tightening force by adjusting the screw (5). There are positioning holes A (7) and positioning holes B (8) on the bearing seat (6). The brake part (9) is fixed on the load-bearing seat (6). The curved elastic section (10) uses the elasticity of the material itself as an elastic part to play the same function as the spring (4). The vertical shaft (11) is assembled Universal wheel is used, and circle sleeve seat (12) is that the caster wheel of assembling band circle sleeve seat is used, and fl...

Abstract

The invention discloses a gravity brake wheel. A roller of the gravity brake wheel is arranged on a cross shaft seat, a bearing seat is arranged above the cross shaft seat, an elastomer is arranged between the cross shaft seat and the bearing seat, a brake component is fixed on the bearing seat and positioned above the roller, and a vertical shaft or a truckle seat can be matched on the bearing seat. By taking a universal wheel of the gravity brake wheel as an example, the gravity brake wheel has the working principle that: an external gravity is applied to the vertical shaft and presses the bearing seat downwards, and the external gravity passes through the elastomer through the bearing seat and is finally transferred to the roller through a cross shaft. The brake component is fixed on the bearing seat and positioned right above the roller, when the pressure is greater than a set value, the elastomer produces compression deformation, and the bearing seat is forced to move downwards till the brake component presses the roller so as to realize gravity braking function. When the universal wheel is changed into a truckle, only the vertical shaft of the universal wheel is detached from the bearing seat, and the truckle seat is arranged on the bearing seat so that the universal wheel becomes the truckle.

Description

technical field [0001] The invention relates to a universal wheel and a caster, especially a gravity brake wheel, which can be made into a gravity brake universal wheel and a gravity brake caster, and also proposes a method for mutual transformation between the universal wheel and the caster . Background technique [0002] Chinese patent application number: 200720102753.9 "Universal Wheel Brake", which provides a reliable, safe and convenient universal wheel brake for braking and releasing the brake. Chinese patent application number: 200510024779.1 "Brake caster with improved structure", relates to a caster with braking function, which solves the problems of low braking force existing in the existing brake caster. The above two patent applications, as well as some existing universal wheels and casters with braking function, when the wheels need to be fixed or need to be rotated, they all use hands or feet to control the locking and loosening of their braking mechanisms. ....
