Abstract
Disclosed is an internal-contracting brake type gravity brake wheel. Rollers are mounted on a cross shaft, outer rubber rings are disposed on outer peripheries of the rollers, a vertical shaft or a mounting seat is mounted on a shaft seat, a cross shaft hole and elastic sheets are arranged on the shaft seat, brake pads are disposed right above a wheel and on two sides of the shaft seat and function in braking, the elastic sheets and the brake pads form a closed loop, and the closed loop improves structural bearing performance, strengthens torsion resistance and also maintains excellent elasticity. The principle of the internal-contracting brake type gravity brake wheel includes that the elastic sheets are bent and deform when the upper end of the shaft seat is pressed downwards under larger gravity, two ends of each brake pad are gathered inwards so as to hold the wheel simultaneously when the shaft seat moves downwards, and when the gravity is sufficiently large, the brake pads are squeezed towards the outer rubber rings on the outer peripheries of the rollers so as to achieve the purpose of braking. The internal-contracting brake type gravity brake wheel has the advantages that an internal-contracting brake type gravity brake universal wheel and an internal-contracting brake type gravity brake caster are provided, and the gravity brake wheel is simpler in structure and better in bearing performance and is more practical.
Description
Technical field
The utility model relates to cardan wheel and castor, especially a kind of brake holding formula gravity brake wheel, and it can be made into brake holding formula gravity braking cardan wheel and brake holding formula gravity brake castor.
Background technology
My Chinese patent application number: " gravity brake castor " 2010102543837, the roller of gravity brake wheel is installed on the transverse axis seat, there is the load-bearing seat top of transverse axis seat, flexible body between transverse axis seat and the load-bearing seat, be fixed with brake member on the load-bearing seat, brake member can be joined vertical shaft or castor seat on the load-bearing seat above roller.With the gravity brake wheel cardan wheel is example, and principle of work is: external force of gravity is applied on the vertical shaft, and to pressing down the load-bearing seat, the load-bearing seat is passed on the roller by transverse axis at last by elastic body.Be fixed with brake member on the load-bearing seat, brake member is directly over roller, and when pressure during greater than setting value, elastic body produces compressive deformation, and the load-bearing seat is forced to move down, and pushes down roller up to brake member, thereby realizes the gravity braking function.The elastic body of mentioning in its patent application also available other more specifically, reasonable plan more.
Summary of the invention
In order further to improve the series of gravity brake wheel, the utility model provides a kind of brake holding formula gravity brake wheel.Main purpose for provide a kind of more concrete, stressed better, practical more gravity brake wheel.
The technical scheme that its technical matters that solves the utility model adopts is: brake holding formula gravity brake wheel, roller is installed on the transverse axis, and the rubber outer ring is arranged on the external diameter of roller, and vertical shaft or mount pad are installed on the axle bed.Transverse axis hole and flexure strip are arranged on the axle bed, and transverse axis hole and flexure strip combine as a whole.There is brake facing on the both sides of axle bed directly over the wheel, play braking, and flexure strip and brake facing are formed a closed loop, and this closed loop has improved the stressed property of structure, has strengthened resistance to torsion, also can keep better elastic.Its principle is: gravity is when pressing down greatly when the upper end of axle bed is subjected to, and flexure strip occurs bending and deformation, and axle bed moves down, the brake facing inward at both ends is drawn in and is embraced to wheel simultaneously, when gravity was enough big, brake facing reached the purpose of brake with the extruding of the rubber outer ring on the way roller external diameter.
The beneficial effects of the utility model are, brake holding formula gravity brake wheel provides a kind of brake holding formula gravity braking cardan wheel and brake holding formula gravity brake castor, and this is simpler, stressed better, the gravity brake wheel of practicality more of a kind of structure.
Description of drawings further specifies the utility model below in conjunction with drawings and Examples.
Fig. 1 is the utility model brake holding formula gravity brake wheel, universal wheeled scheme drawing.
Fig. 2 is the utility model brake holding formula gravity brake wheel, the scheme drawing of horn ring formula.
Fig. 3 is the utility model brake holding formula gravity brake wheel, universal wheeled expansion scheme drawing.
Fig. 4 is the scheme drawing of the axle bed part of the utility model brake holding formula gravity brake wheel.
1. rollers among the figure, 2. transverse axis, 3. rubber outer ring, 4. axle bed, 5. vertical shaft, 6. mount pad, 7. transverse axis hole, 8. resilient ring.
The specific embodiment: Fig. 1 is the utility model brake holding formula gravity brake wheel, and universal wheeled scheme drawing, roller among the figure (1) are installed on the transverse axis (2), and rubber outer ring (3) is arranged on the external diameter of roller (1), and vertical shaft (5) is installed on the axle bed (4).
Fig. 2 is the utility model brake holding formula gravity brake wheel, the scheme drawing of horn ring formula.Roller among the figure (1) is installed on the transverse axis (2), and rubber outer ring (3) is arranged on the external diameter of roller (1), and mount pad (6) is installed on the axle bed (4).
Fig. 3 is the utility model brake holding formula gravity brake wheel, and universal wheeled expansion scheme drawing is equipped with transverse axis (2) on roller among the figure (1), transverse axis (2), rubber outer ring (3), the axle bed (4), and vertical shaft (5) is installed on the axle bed (4).
Fig. 4 is the scheme drawing of the axle bed part of the utility model brake holding formula gravity brake wheel, transverse axis hole (7) and flexure strip (8) are arranged on the figure central axis seat (4), the both sides of axle bed (4), top over against wheel is a brake facing, play braking, flexure strip (8) is formed a closed loop with brake facing, this closed loop has improved the stressed property of structure, strengthen resistance to torsion, also can keep better elastic, in addition, for improving the friction force of brake, at brake facing and the arc surface that roller (1) cylindrical contacts, promptly be carved with teeth groove on the inner arc surface of brake facing, this teeth groove is similar to the annular knurl on some Anti-slip handles.Its principle is: when the upper end of axle bed (4) is subjected to big gravity when pressing down, flexure strip (8) occurs bending and deformation, axle bed (4) moves down, the brake facing inward at both ends is drawn in and is embraced to wheel simultaneously, when gravity is enough big, brake facing reaches the purpose of brake with the extruding of the rubber outer ring (3) on way roller (1) external diameter.
Claims (3)
1. brake holding formula gravity brake wheel, it is characterized in that: transverse axis hole and flexure strip are arranged on the axle bed, and there is brake facing on the both sides of axle bed directly over the wheel, and flexure strip and brake facing are formed a closed loop.
2. brake holding formula gravity brake wheel according to claim 1, it is characterized in that: transverse axis hole and flexure strip combine as a whole.
