Description

M262378 Fourth, the creation description [new type of original brake structure to move [prior art general wheel frame 6, and the wheel 3 to the side convex block 6 3 the turning piece 6 1 convex, to limit the 3 1 and side The side piece is invalidated by pressing the bump of the wheel 3. Moreover, the piece 6 1 only pushes the force of the other (1) technically related to a brake lever in order to cast a wheel brake structure, especially a technique with a shaft that can be directly inserted into the wheel center to produce a braking effect. ] Know this wheel frame 6 pieces 6 1 6 3 3 6 This wheel, the piece 6 body 6 6 36 1 car structure, such as the sixth has two side pieces 6 1, one of the caster brake frame 6 side pieces pivoted There is a rotation 1 that protrudes and a convex that makes the 11, body 6 2 of the known 1 convex 2, because 1 and the side can not be tight, a convex part 6 is rotated and forced to converge the car part 6 Therefore, the sheet 6 closely abuts the block 6 3 11; piece 6 3 makes the side move, and the structure, phase 1 1 is used when the convex piece of 1 is used to press the wheel, and the convex piece 6 is generated to abut a section 6 body 6 as shown in the figure for the sacral area. 6 3, and the side piece, after the brake block 6 3 1 1 turns the piece 6 towards the effect of the wheel brake, after forcing the side time, 1 1 each other 2, so that it has a wheel body 6 2 the turn 6 1 When it comes to body 6 results. The 6 piece of 3 is worn to become the brake piece 6. The side piece 2 should be rotated to press against the bump 6 1 After the moving piece 6 is shifted, the car effect 6 1 is pressed against the brake structure of the wheel body 6 2 due to the side The body 6 2 has insufficient resistance between the two, and rotates on the outer body 6 2 to make the braking effect poor. There is a conventional caster brake structure, as shown in FIG. 7, which has a wheel frame 7, which is pivotally connected to a wheel body 7 1, and the wheel frame 7 can still contact the underside of the wheel with the side piece. Make round

Page 8 M262378 IV. Creation instructions (5) In the other side wall 12 of the wheel frame 1 opposite to the braking device 3, one end of the fixing rod 4 1 extends along the rod body 3 3 of the braking device 3 And a hook portion 4 1 1 is bent downward at the end, so that the hook catches the moving piece 3 2 of the brake device 3 and is slid on the rod body 3 3-the end portion 3 2 1 at the end, and the hook portion 4 1 1 has an inclined surface 4 1 3 and 3 2 2 respectively corresponding to the end portion 3 2 1 so that the end portion 3 2 1 is hooked on the hook portion 4 1 1 and the other end of the fixing rod 4 1 is Then, the side wall 1 2 is extended to form a control section 4 1 2. Pressing the control section 4 1 2 can release the hook portion 4 1 1 at the other end from the end portion 3 2 1 of the moving piece 3 2, and the An abutment member 4 2 is provided between the control section 4 1 2 and the side wall 12 to abut the control section 4 1 2 _ so that the hook portion 4 1 1 does hook the end of the moving piece 3 2 In the embodiment, the abutment member 4 2 is composed of a spring 4 2 1 and a guide rod 4 2 2, and the spring 4 2 1 is sleeved on the guide rod 4 2 2. The guide rod 4 2 2 is attached to the side wall 1 2 at one end and the control section 4 1 2 at the other end. The two ends of the spring 4 2 1 are caused to abut the side wall 12 and the control section 4 1 2 respectively, so as to abut the control section 4 1 2 by the elastic force of the spring 4 2 1. As a result, when braking, as shown in FIG. 3, the convex button 3 5 of the actuating piece 3 2 of the braking device 3 is pressed to move the actuating piece 32 together with the brake lever 31 in the direction of the wheel body 2. And insert the brake lever 3 1 into one of the sockets 2 3 of the wheel * body 2 to restrict the rotation of the wheel body 2, and when the action piece 3 2 moves in the direction of the wheel body 2, the end portion 3 of one end thereof 2 1 will hook the hook 4 1 1 of the fixing rod 4 1 of the fixing device 4 to fix the moving piece 3 2 while fixing the brake lever 3 1 to the socket 2 of the wheel body 2 3

Page 9 M262378 4. In the description of creation (6), the effect of braking is achieved. When the brake is to be released, as shown in FIG. 5, the control section 4 1 2 of the fixing rod 4 1 of the fixing device 4 is pressed to release the hook portion 4 1 1 at the other end of the fixing rod 4 1 from the moving piece 3 2 The end portion 3 2 1 is reset by the elastic force of the elastic body 34 to drive the brake lever 31 from the hole 2 3 of the wheel body 2 to release the braking state of the wheel body 2 After releasing the control section 4 1 2 of the fixing rod 41, the fixing rod 41 is abutted by the abutment member 4 2 to return the hook portion 4 1 1 of the fixing rod 41 to its original position. In order to fix the brake device 3 again. Since the brake lever 3 1 of the brake device 3 is directly inserted into the jack 2 3 in the wheel body 2 φ, the rotation of the wheel body 2 can be restricted, and after long-term use, the brake effect can be achieved. In addition, the brake lever 31 will not be pressed against the surface of the wheel body 2 and will not cause the surface of the wheel body 2 to be depressed, and of course, it will not affect the smoothness of the wheel body 2 walking. In addition, the socket 2 3 of the wheel body 2 is designed to have an oval shape. When the wheel frame 1 sinks under heavy pressure, the brake lever 3 1 of the brake device 3 can still be inserted into the socket 2 3 without error. In order to limit the rotation of the wheel body 2. In addition, the end portion 3 2 1 of the moving piece 3 2 of the brake device 3 and the hook portion 4 1 1 of the fixing rod 4 1 of the fixing device 4 are respectively provided with corresponding inclined surfaces 3 2 2 and 4 1 3 so that After the end portion 3 2 1 of the moving piece 3 2 is moved, it can be pushed by the two inclined surfaces 3 2 2, 4 1 3 to make the end portion 3 2 1 easier to hook on the hook portion 4 1 1. In order to facilitate the operation of the braking device 3, in addition, the fixing rod 4 1 of the fixing device 4 is composed of an abutment member 4 2

Page 10 M262378 IV. Creation description (7) The top part of the fixing rod 4 1 can make the hook 4 1 1 surely catch the end 3 2 1 of the moving piece 3 2 to make the brake of the wheel body 2 The state is more stable. The disclosure of the embodiments described above is used to explain the creation, and is not intended to limit the creation. Therefore, any numerical change or replacement of equivalent components should still belong to the scope of the creation. From the above detailed description, those skilled in the art can understand that this creation can indeed achieve the aforementioned purpose, and it has indeed complied with the provisions of the Patent Law, and filed a patent application.
