Abstract
The utility model discloses a brake type hardware castor for medical use. The castor comprises a roller, a bracket, a mounting screw rod, a brake pedal, a start pedal and a brake sheet spring, and is characterized in that the longitudinal cross section of the brake sheet spring has an irregular Y-shaped structure; one end of an upper foot of the Y-shaped structure is fixed with the bracket through a rotating rivet; and one end of a lower foot of the Y-shaped structure is movably connected with the start pedal through a movable shaft. In a braking state, the head part of one end of an upper foot of the Y-shaped structure tilts and is inserted in a disk brake gear; and the other end of the upper foot of the Y-shaped structure is detached from the front end of the brake pedal. In the utility model, the bracket is movably connected with the mounting screw rod through a bearing, thereby effectively reducing the noise in the movement of the castor; the special structure of the brake sheet spring, and the movable triangular position of the movable shaft, a brake shaft and a shear shaft are adopted; and the utility model utilizes the lever principle and realizes more flexible and convenient braking and starting.
Description
Technical field
The utility model belongs to mechanical Hardware fitting, relates to a kind of castor, especially a kind of medical brake type five metals castor.
Background technology
Castor is a kind of common mechanical Hardware fitting, and the footing that is installed in furniture, go-cart, lathe, hospital car etc. usually to be making things convenient for moving of object, when movement of objects behind the destination, need make the castor braking.The major defect that existing in the market brake type castor exists is: the one, generally adopt the two-orbit roll structure at the installation end of object footing and castor, when mobile noise greatly, turn to dumb; The 2nd, the brake structure instability, brake is not exclusively." the structure improved brake castor " that provides for 200520040556.X number as Chinese patent, as shown in Figure 2, though this technical scheme has solved castor brake structure instability, the incomplete problem of braking, but because its brake facing structure design is unreasonable, its brake facing repeated use easy deformation causes realizing drag, and wants brake off very dumb after this structure braking.
Summary of the invention
Development purpose of the present utility model is to overcome the defective that existing product exists, and provides a kind of low noise, braking, the medical flexibly brake type five metals castor of startup.
A kind of medical brake type five metals castor of the present utility model, comprise roller, support, installation screw mandrel, brake pedal, startup pedal, brake spring sheet, it is characterized in that: the vertical section of described brake spring sheet is irregular " Y " font structure, wherein last pin one end of " Y " font is fixed by rotation rivet and support, and leftover bits and pieces one end of " Y " font flexibly connects by a movable axis and startup pedal.
Under the starting state, " Y " font of described brake spring sheet end afterbody of getting a foothold contacts the front end closed contact of the pin other end and brake pedal on " Y " font of brake spring sheet with the roller surface gap.
Described brake pedal flexibly connects by brake axle and support, and brake pedal is again by cutting moving axis and starting the pedal flexible connection simultaneously.
Described movable axis, brake axle, the axle center of cutting three of moving axis are in vertex of a triangle under starting state, three axle center is in a straight line under braking mode.
Described support flexibly connects with screw mandrel is installed by bearing, the screw mandrel bottom is installed is fixed with the disc brake tooth.
Under braking mode, the head perk of last pin one end of described brake spring sheet " Y " font embeds the disc brake tooth, and the front end of the pin other end and brake pedal breaks away from " Y " font of brake spring sheet simultaneously.
The beneficial effects of the utility model are: adopt support by bearing and the mode that the screw mandrel flexible connection is installed, effectively reduce the noise of castor in moving; Adopt special construction and movable axis, the brake axle of brake spring sheet, the moving trihedral change in location of cutting three of moving axis, utilize lever principle well, realize braking and start more flexible.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a kind of structural representation of existing castor.
Among the figure: 1: bearing cap shim; 2: screw mandrel is installed; 3: bearing; 4: bearing carrier ring; 5: the disc brake tooth; 6: support; 7: the rotation rivet; 8: the brake spring sheet; 8a: last pin one end of " Y " font; 8b: the pin other end on " Y " font; 8c: " Y " font end afterbody of getting a foothold; 9: wheel shaft; 10: brake pedal; 10a: brake axle; 10b: cut moving axis; 11: start pedal; 11a: movable axis; 12: roller.
The specific embodiment
Be further elaborated with regard to the specific embodiment of the present utility model below in conjunction with description of drawings, as shown in Figure 1: a kind of medical brake type five metals castor of the present utility model, comprise roller 12, support 6, installation screw mandrel 2, brake pedal 10, start pedal 11, brake spring sheet 8, it is characterized in that: the vertical section of described brake spring sheet 8 is irregular " Y " font structure, wherein the last pin one end 8a of " Y " font is fixing by rotation rivet 7 and support 6, and leftover bits and pieces one end of " Y " font passes through a movable axis 11a and starts pedal 11 flexible connections.
Under the starting state, " Y " font of described brake spring sheet 8 end afterbody 8c that gets a foothold contacts the front end closed contact of pin other end 8b and brake pedal 10 on " Y " font of brake spring sheet 8 with roller 12 surface gap.
Described brake pedal 10 flexibly connects by brake axle 10a and support 6, and brake pedal 10 flexibly connects with startup pedal 11 by cutting moving axis 10b again simultaneously.
Described movable axis 11a, brake axle 10a, the axle center of cutting three of moving axis 10b are in vertex of a triangle under starting state, three axle center is in a straight line under braking mode.
Described support 6 flexibly connects with screw mandrel 2 is installed by bearing 3, screw mandrel 2 bottoms is installed is fixed with disc brake tooth 5.
Under braking mode, the head perk of the last pin one end 8a of described brake spring sheet 8 " Y " font embeds disc brake tooth 5, and the front end of pin other end 8b and brake pedal 10 breaks away from brake spring sheet 8 " Y " font simultaneously.
The utility model adopts support 6 by bearing 3 and the mode that screw mandrel 2 flexible connections are installed, and effectively reduces the noise of castor in moving; The special construction of employing brake spring sheet 8 and movable axis 11a, brake axle 10a, the moving trihedral change in location of cutting three of moving axis 10b are utilized lever principle well, realize braking and start more flexible.
