A shaft 3 is arranged, and a pair of swing rods 4 are fixed on each of the two rods 3, and a connecting rod 5 is placed between the front and rear opposite swing rods 4, and one side is The slinger 2 is provided with an operating frame 6' and the above-mentioned wheel 2 has a specially designed knot 2; Ϊ = _ shaft 3 Μ angle of rotation, and can control the wheel: one: yes or better This makes the wheel unable to turn 'and has this function in the four rounds (not shown). Therefore, as shown in the third figure, #操作架6 is at a level of 2 Μ free walking and steering 'If you will operate '6: lower correction, the shaft 3 on the same side as the operating frame 6 will be driven downwardly R The other-end shaft 3 of the bed frame 1 is also synchronously rotated by the movement of the swing rod 4 and the connecting rod 5, so that the four wheels 2 under the hospital bed are simultaneously braked; otherwise, when the operating frame 6 is pulled upwards and inclined The shaft 3 will rotate upwards, so that the four wheels of the bed release the brakes at the same time, but at least one of them ^ 2 will not be able to turn, so that the bed can be moved straight and kept. Stable straight down without arbitrarily turning. However, the above-mentioned operation structure controls the walking, braking or straightening of the wheel 2 by the upper and lower swings 5 M296695 of the operating frame 6, but due to the design relationship of the wheel 2 itself, the shaft 3 must be rotated to a specific Angle, in order to achieve the role of walking, braking or straight, so we found that the operating frame 6 must swing up or down between about thirty-five to forty-five degrees, can start the brakes of the wheel and control the wheels can not turn control. Therefore, because the operation angle of the operation frame 6 is too large, it is necessary not only to retain a large operation space, but also to facilitate the operation, and because the operation of the operation frame 6 is too large, such a design cannot be ergonomically. In addition to the increase in operational difficulty, it is more likely that the phenomenon of being unable to be in place or slipping out during operation may occur, which may easily lead to dangerous situations. [New content] The reason is that in order to improve the above-mentioned problems, the technical method adopted by the present invention is to install a shaft between adjacent wheels at one end of the hospital bed, and to fix a control rod on the shaft. And an operation frame is pivoted on the bed frame of the corresponding bed, and then a linkage is connected between the control pendulum and the operation frame to enable the swinging of the upper and lower angular positions of the operation frame through the linkage The control swing rod drives the shaft to rotate at different angles. Therefore, when the operating frame of the present invention is oscillated at different angular positions above and below, and the shaft is driven to rotate at different angles to control the control of different situations of the wheel, the angle of the swing of the operating frame can be greatly reduced. It is more ergonomic and user-friendly, which increases the ease of operation and reduces the occurrence of dangerous phenomena such as slippage during operation. Therefore, the present invention can be fully understood by the following embodiments in conjunction with the accompanying drawings, and implemented according to the following: 6 M296695 [Embodiment] Please refer to the fourth, fifth and sixth figures, not new The beds are multiplied by ί. The four corners are equipped with wheels 2 that can be freely steered. Three of the wheels have the function of braking, while the other wheel has the function of controlling the steering and is adjacent to the two ends of the bed. A shaft 3 is disposed between the two wheels, and a pair of swing rods 4 are respectively fixed on the shafts 3 on both sides, and a connecting rod 5 is pivotally connected between the ends of the front and rear swing rods 4 Then, another control pendulum 7 is fixed on the shaft 3 on one side, and an operation frame 6 is pivoted on the bed frame 1 on the same side, and the connection between the control pendulum 7 and the operation frame 6 is connected. A linkage member 8 enables the upper and lower swings of the operating frame 6, and the shaft 3 is driven to rotate by the linkage member 8 and the control swinging rod 7, and the other side is driven by the swinging rod 4 and the connecting rod 5 The synchronous rotation of the shaft 3 is performed. Referring to the seventh figure, when the operating frame 6 is in the middle of the horizontal position, the four wheels of the hospital bed can be freely rotated, so that the bed can be freely moved and turned, but when the operating frame 6 is swung downward. (As shown in the eighth and ninth figures), the shaft 3 on the side is driven to rotate by the linkage member 8 and the control swing rod 7, and when the shaft 3 on the side is rotated, the swing rod 4 and the joint are also connected. The rod 5 drives the rotating rod 3 on the other side to rotate synchronously. Therefore, after the two shafts 3 are rotated downward to the position, the four wheels 2 under the hospital bed are simultaneously braked, and the movement of the bed is stopped. On the contrary, when the operating frame 6 is pulled upwardly (as shown in the tenth and eleventh figures), the shaft 3 on the same side will also rotate upward through the linkage of the linking member 8 and the control swinging rod 7, at this time, At least one of the beds that can control the steering wheel 2 will be locked and can only go straight and cannot be turned, so that the 7 M296695 bed can be more stable and can not be arbitrarily turned and can be fascinated when moving forward. Mover. Therefore, the shaft 3 is rotated at different angles by swinging the upper operating frame 6 at different angular positions to control the different conditions of the wheel 2, and the operating frame 6 is not directly coupled to the shaft 3. Rather, the shaft 3 is rotated indirectly via the control swing rod 7 and the linkage member 8, thereby greatly reducing the angle of the swing of the operating frame 6, so that the ergonomics can be more ergonomically facilitated by the user, and as such Increase the ease of operation and reduce the risk of slipping during operation.
