Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of castor, relates in particular to a kind of front brake brake castor.
Background technology
Castor is a kind of common product, refers to be connected with the bottom of conveying arrangement, and the wheel that can freely change direction, it is broadly divided into fixed castor and rotary-type castor.It is installed on the bottom of utensils such as furniture, go-cart or lathe usually, and utensil can be moved flexibly and easily.Because utensil needs transfixion after moving and finishing, therefore be necessary at castor a brake equipment to be set.
Traditional brake equipment comprises brake facing and the slipper that is arranged on the roller homonymy more, brake facing adopts the spring steel plate punching out to be shaped, keep fixing distance between brake facing and the wheel, make brake facing exert pressure for the wheel side and make it to roll and reach braking effect by shaking slipper, this brake equipment can not avoid whole roller and support with respect to the rotation of utensil, thereby can not make utensil transfixion under the castor braking mode, when the weight of utensil is heavier, it is motionless often to be difficult to that roller is checked fully, and practicality is lower.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist at prior art, has proposed a kind of front brake brake castor of simple in structure, good braking effect.
The purpose of this utility model can realize by following technical proposal: a kind of front brake brake castor, comprise support and the roller that is hinged with support, described support upper end is connected with rotating disk, described support hinged inside has pedal, described rotating disk bottom is provided with the draw-in groove that some edges circumferentially arrange, it is characterized in that, described support inboard also is connected with the folding spring leaf that takes the shape of the letter U, described spring leaf is between rotating disk and roller, the opening part that described pedal the inner is positioned at the opening part of spring leaf and pedal the inner can make spring leaf when pedal is stepped on becomes big, and the two ends of the opening part of described spring leaf have respectively when pedal is stepped on and can and can snap in buckle in the above-mentioned draw-in groove with the contacted brake shoes of roller.
Pedal the inner is positioned at the opening part of spring leaf, when pedal was operated, pedal the inner strutted the opening part of spring leaf, made the brake shoes of spring leaf opening part to pressing down and buckle is upwards lifted, thereby brake shoes presses down the pair roller that contacts with roller and brakes, and roller can't be rotated again; Buckle is lifted and is snapped on then in the draw-in groove of rotating disk bottom, and rotating disk can't circumferentially rotate again, so just makes roller can be in complete actionless state.
In above-mentioned front brake brake castor, the end inboard that described spring leaf is provided with buckle has towards the positioning plate of the opening part inclination of spring leaf, and described pedal the inner has the baffle plate that is resisted against on the positioning plate.
Because positioning plate tilts towards the opening part of spring leaf, and pedal the inner is resisted against on the positioning plate by baffle plate, makes spring leaf to be strutted when pedal can only be operated, and has prevented that like this maloperation from appearring in moving process.And when push down on the pedal, the baffle plate of pedal the inner and positioning plate break away from, and an end of spring leaf is upwards pushed up, and make buckle snap in the draw-in groove.
In above-mentioned front brake brake castor, the end that described spring leaf has brake shoes has a curved groove, and described pedal the inner has projection, and described brake shoes is positioned at the nadir place of groove, and described projection can fall in the groove when pedal is stepped on.
When pedal is stepped on, the projection of pedal the inner is rotated along with pedal and when falling in the groove, this moment, spring leaf was strutted to greatest extent, thereby made brake shoes fully contact with roller.
In above-mentioned front brake brake castor, described rotating disk comprises top rotary table and lower rotary table, and described draw-in groove is positioned at the bottom of lower rotary table.
In above-mentioned front brake brake castor, also be connected with on the described support for the connecting panel that is connected usefulness with equipment, described connecting panel is positioned at the top of top rotary table, and described connecting panel, top rotary table and lower rotary table link by the punching press riveted way.
Compared with prior art, this front brake brake castor is simple in structure, utilizes the spring leaf pair roller and the rotating disk that take the shape of the letter U to brake simultaneously when pedal is stepped on, and guarantees that roller can be in static state fully, good braking effect when braking; In addition, the spring leaf that is used for braking in this front brake brake castor takes the shape of the letter U, and is simple in structure, novel, and is easy to make the practical value height.
