The caster structure of the car squat effect. [First Technology] Press, there is currently a caster structure (1) (see the first figure), that is, the US invention No. 5, 632, 360 patent, straight to teach, /, in..., handle (10 At the other end, there is a 3L tooth (11), which is taught by 4, and the pressure is δχ..., the handle (丨〇), so that the latch (11) and the rim (1) 2) The cogging (1 3) phase card is ready for use.. The card system is used to achieve the braking effect; however, the brake car, the raft structure is due to its stalk handle ( , , ^ ^ 枘 UU) Early body parts, so that the power of the brakes is too J, Tian Qi women's dress in the seat, the human body will reluctantly door, the birth of "earth and people under the weight of the pressure" is extremely easy to press the ankle due to gravity. 冓 can not be used at all The two-wheeled large-sized two-wheeled shank (10) is easily broken when it is in motion. [Invention] In view of the above-described conventional brake device Λ A # ^ σβ, the inventor of the present invention has perfected the cup. The idea of refinement, for the first time to create the invention. wh elaborate research and improvement 'The main purpose of the invention is to provide - easy component composition, by dust or pull The action: can be wheeled = its system is minimalist or unloading, and its rear wheel cover is used when the caster is pushed by external force, the wheel body will still roll when the situation occurs / not like the customary: Mingzhi - The caster structure comprises a handlebar, a body rim, a t-axis, an upright shaft and a positioning tip, wherein the body is inserted into the vertical hole of the vertical shaft of the example, and the other side is suitable for: straight 5', ..., 201000350 square hole accommodated by the soap block, and a through hole for positioning the tip is arranged below the square hole, and one side of the through hole is provided with a straight surface and a curved surface on the side of the receiving ear of the handle Fitted plane = curved surface; the brake block has a latch on one side that can cooperate with the teeth provided on the inside of the wheel cover, and the bottom surface of the toothed side is provided with a contact with the curved surface of the top of the handle of the handle The inclined surface of the vehicle is placed in the square hole of the body, so that the receiving ear of the handle is received on both sides of the bottom of the body, and the positioning pin is inserted to make the central shaft of the body pass through the shaft hole of the body. Set at both ends of the center shaft: =·: Make the inner teeth of the wheel cover and the brake block _ side (4) Cooperating to complete the structure. With the above design of the invention, the positioning of the shank of the shank is achieved by the arc surface of the side of the receiving ear and the arc surface of the lower side of the body as a fulcrum, and at the same time, the positioning tip is The fulcrum uses the principle of lever to make the stalk of the stalk handle to push the brake block to complete the brake or to return to the original position to release the brake; and when the invention is braked, the shank of the shank receives the flank of the top of the ear and the flank of the brake stop The inclined surface provided on the bottom surface is clamped, and the arc surface "the line and the positioning tip "A angle is greater than 9 degrees, and the self-locking effect is generated, so that the handle of the handle is not pressed by gravity and is released from the brake stop block. Therefore, the present invention In addition to being different from the general caster structure, and the resulting braking effect is good, there will never be a lock after sliding. [Embodiment] (Refer to 2-4 to 4), the caster structure of the present invention has been equipped with a handle (2〇), a body (21), a brake block (22), and a second wheel cover (23). a central shaft (24), a vertical shaft (25) and a positioning tip (other), wherein the handle (20) is provided with a pressing surface (2〇1) on one side and a pressing surface (2〇1) on the other side. 2 ears (202), the top surface of the receiving ear (2〇2) is curved (2〇3), and the receiving ear (other 2) 6 201000350 is the outer side (204) and one The arc surface (205) is combined, and a through hole (206) for inserting the positioning tip (26) is disposed at the receiving ear (202); the body (21) is provided with a shaft hole at the center thereof (210) ), one side is provided with an upright hole (211) for inserting the vertical shaft (25), and the lower side is provided with a square hole (212) for accommodating the stop block (22). A circular flange (213) extends below the hole (21 2), and a center of the circular flange (213) is provided with a through hole (214) for inserting the positioning tip (26), and the circular flange (213) is on the side There is a receiving ear (202) with the handle of the handle (20) - the side of the curved surface (205) Cooperating with the curved surface (215), and the curved surface (215) extends further in the direction of the axial hole 210 (210) to the side of the receiving ear (2〇2) of the handle (2〇) (204) The matching plane (21 6); the brake block (22) is provided with a groove (220) for receiving the receiving ear (202) on the two sides of the bottom surface of the brake handle (20), one side of which is provided a latch (221) that can be engaged with a latch (231) provided inside the wheel cover (23), and a bottom surface of the latch (221) is provided with an ear (2〇2) for receiving the handle (2〇) a bevel (222) that contacts the top curved surface (203); the wheel cover (23) is internally provided with a ring of teeth (231) that cooperate with the teeth (221) of the brake block (22); The brake block U (22) is placed in the square hole (212) provided under the body (21), so that the receiving ear (202) of the handle (20) is received by the round flange provided by the body (21) (213) On both sides, the through hole (206) of the receiving ear (2〇2) and the through hole (214) of the circular flange (213) of the body (21) are inserted into the positioning tip (26), so that The body (21) is combined with the handlebar (2〇), and the shaft hole of the middle body (21) of the jaw body (21) 21〇), a wheel cover (23) is arranged at each end of the central shaft (24) so that the internal teeth (231) of the wheel cover (23) are aligned with the teeth (221) of the brake block (22) side. At this time, the pressing surface (2〇1) of the handle (2〇) is horizontally and is supported by the ear (2 〇 2) outer straight surface (2 〇 4) and the body (2 upper) circular flange (213) - The plane of the side (216) is in contact. 7 201000350 When in use (see the fourth and fifth figures), by pressing the pressing surface (2〇1) of the handle (2〇), the receiving ear (202) of the handle (20) will The positioning tip (26) rotates at an angle for the fulcrum, and the arc surface (2〇5) of the outer side is matched with the arc surface (215) provided on the side of the circular flange (213) below the body, and the brake block is (22) moving in the direction of the internal latch (231) of the wheel cover (23), so that the latch (221) provided in the brake stop (22) matches the latch (231) of the wheel cover (23). The top curved surface (2〇3) of the receiving ear (202) of the handlebar (20) is opposite to the inclined surface (222) provided under the side of the latching (221) of the brake stop (22), and the curved surface (the curved surface) 2〇3) The angle between the center line (A) and the center of the positioning tip (26) is greater than 9 degrees, and the self-locking effect is achieved. In this case, the wheel cover (23) is locked and positioned to complete the brake of the caster (2). , do not get detached by gravity; when the brakes of the casters (7) are to be released, the handles of the brakes will be pulled (if they are pulled back to the original position, the teeth (221) of the brake stops (22) are removed from the wheel cover (Μ) [Simple description of the diagram] The first picture Schematic diagram of conventional cross-section action ij second diagram is a three-dimensional combination diagram of the present invention.
