Description of the invention: [Technical field of the invention] The present invention relates to a caster, in particular to a saw tooth groove which is provided by pressing the handle of the handle to drive the brake block to be inserted into the inside of the roller, thereby fixing the roller It is impossible to roll, so that the casters are in the braking state of the caster. [Prior Art] Press, the caster (1) seen in the general market, (please refer to the first A picture) 'The caster (1) is provided with a control body (11) between the rollers (10) on both sides thereof. The two sides of the roller (10) are provided with a card groove (12) for the control body (11) to be engaged, and the control body (ii) is in contact with the card groove (丨2). a lever (13) is provided; when the control body (u) is in a relaxed state, the control body (n) is such that the lever (13) is engaged in the lower side of the card groove (12). The roller (1〇) on both sides of the caster (1) can smoothly slide on the ground; (please refer to the first B), when the control body (11) is pressed, the lever (13) is clamped on When the inside of the card groove (丨2) is inside, the roller (1〇) is restrained by this and is fixed at this position, so that the caster (1) cannot be slidably moved on the ground, but is in a braking state. SUMMARY OF THE INVENTION [7] The inventor developed a "caster brake structure" that is different from the conventional one based on years of experience in the industry and multi-party testing. The structure of the caster brake of the present invention utilizes the brake block and the handle of the brake to sigh, so that when the handle is pressed, the brake stop can be driven to lock the two rollers of the caster, and the entire caster is in a braking state. 200904686 The structure of the caster brake of the present invention comprises a body, a roller, a brake stop and a handle, wherein the center of the body is provided with a shaft hole, and a receiving groove for receiving the brake block is arranged on one side thereof.

The top edge of the two sides is also curved, and the two sides of the receiving seat are respectively provided with a plug hole; the brake block is placed in the receiving groove of the body, then the sides of the brake block are The edge of each of the rims is placed outside the accommodating slot; the socket of the shank is placed on one side of the accommodating groove, and the spigot holes on both sides are aligned with the burrowing holes of the body, and then the spigots are inserted. Set the upper and lower arc surfaces of the front edge of the joint to the outer arc of the curved surface and the arc of the body and the side. When '^时', the top edge of the drum is just right. (4) After the bottom of the block is inserted into the shaft hole of the main body, the two ends of the block are combined with each other. The wheel is combined, then the straight is straight, and the rTWnf I- j... The card edge on both sides of the block stops in the roller and/or the surface with the wrong tooth is opposite to the ore groove provided inside the roller. The above-mentioned design of the present invention uses the handle of the handle to press the λ. ',, and the soap stop to make the saw teeth and the roller that is fixed and cannot be rolled, the front of the handle, the handle, and the handle of the handle. Under the edge of the arc and the:: = the stability of the car's handle, - 200904686 [Embodiment] (see the second and third figures) "The caster (2) brake structure of the present invention, including the body (20 ), the shaft center (21), the roller (22), the brake block (23) and the brake handle (24), wherein the center (2〇) is provided with a shaft hole (201) at the center thereof, and a brake is provided on one side thereof. The accommodating groove (202) placed in the block (23) is provided with a spigot hole (2〇3) under the accommodating groove (202); and the brake block (23) is provided with a groove at the bottom portion thereof ( 23〇), and each side has a card edge (231), and the card edge (231) is provided with a plurality of serrations (232) on one side of the contact with the serration groove (220) provided inside the roller (22). The serration (232) is sized to fit the serrated groove (22〇) provided inside the roller (22); the handle (24) is provided with a pressing edge (240) on one side thereof. A receiving seat (241) is protruded from the inner side of the pressing edge (240), and the front edges of the receiving seat (241) are formed by the upper and lower curved surfaces (242) and (243), and the two sides thereof are topped. The edge (245) is also curved, and the receiving seat (241) is provided with a cutting hole (244) on both sides; the brake block (23) is placed in the receiving groove (202) of the body (20) Inside, the card edge (231) on both sides of the brake block (23) will fall outside the receiving groove (202); the socket (241) provided on the handle (24) is received by the body (20) One side of the accommodating groove (202) is provided, and the spigot holes (244) on both sides are aligned with the spigot holes (203) of the body (20), and then the spigots are inserted into the spigots (25). The shank (24) can be offset by one of the upper and lower faces (242) and (243) of the front edge of the receiving seat (241) and the arc edge (204) provided on the side of the body (2〇), while The top edge (245) of the receiving seat (241) will just fall in the groove (230) provided at the bottom of the brake block (23); the shaft center (21) is passed through the shaft hole of the body (20) (201) After that, the two ends are combined with a roller 200904686 (22), then the brake block (23) two The card edge (231) will fall to roll • wheel (22) inside, and so that it is provided with serrations (232) of the serration groove and the inner peripheral side of the roller (22) is provided (220) opposite. When in use (see the fourth and fifth figures), when the handle (24) is in a relaxed state, it is the arc of the arc surface (242) and the body (20) above the leading edge of the socket (241). The edge (204) contacts, at this time, the brake stop block (23) is located inside the body (20) receiving groove (202), and the serration (232) of the card edge (231) is not inside the roller (22). When the serrated groove (220) is engaged, the roller f > ' (22) is not locked, so the displacement can be smoothly performed; when the handle (24) is pressed (see the sixth and seventh figures), The top edge (245) of the receiving seat (241) is rotationally displaced in the bottom groove (230) of the brake stop block (23), and the brake stop block (23) is accommodated in the body (20). 2 〇 2 ) When the outer side is pushed, the serration (232) of the card edge (231) is matched with the serration groove (220) inside the roller (22), and the roller (22) is not locked by the roller, but is in the brake The state 'simultaneous' shank (24) is such that the arc surface ^ (243) under the leading edge of the socket (241) is in contact with the arc edge (204) of the body (2 〇).
