Description of the invention: [Technical field to which the invention pertains] The present invention is characterized in that the operation is performed from a two-way oil type, and the oil pressure of each movable unit of the operating table is red-cut, in particular, a hydraulic pressure recording device, and The woman turned to the two-way pressure system design. Two-way oil in the direction of oil supply [Prior Art] Ο Ο Press, the movable unit of the operating table (such as multi-shift, bed lift, brake or brake), the bed surface is used as the oil circuit switching unit. The hydraulic system is used as the action: at least two electromagnetic readings are required for the hydraulic cylinder of the solenoid valve, such as - when the group of cylinders, the cost will be roughly proportional to the UUi multi-secret pressure circuit or coil failure, With the electromagnetic ^ solenoid valve drive ^ solenoid valve control oil circuit switch turn t good and take the drive to achieve, it is indeed the cost of ns, by - a ί, the village "hand money position = road ==== ===Polygon design, so all Di-turn oils are high in magnetic strength, so this will increase the installation space of the hand-station base, because the operating platform lifts the key factors ^_ and 2 the thickness of the base is indeed The impact lift sleeve can grow! When the centimeter is 1 cm, each section is 4 cm. Therefore, the conventional rotation 1: the stroke of the lift can be increased at most. The design of the transfer secret room threatens the lifting stroke of the operating table plus the conventional rotary surface. The oil pipe joint lock 201043215 should be tightened to the downward oil hole to lock the valve body to fix the sheet metal part, and then together with the valve. The body-fixed sheet metal piece is mounted on the base of the operating table, so that when the maintenance is performed, the entire rotary oil-dust valve must be removed together with the valve body fixed meal, and then the valve body is fixed separately. It is very inconvenient to remove the τ, which is attached to the oil pipe of the downward oil hole, and the valve body is required to fix the sheet metal member. The main purpose of the present invention is to provide an operating table. The bi-directional hydraulic system is designed so that the movable unit driven by the hydraulic cylinder of the operating table is connected to the two-way oil and county through a switching valve f, so that the two-way secret pump mismatch can be switched back and forth to control the oil supply direction to The selected external oil valve position corresponding to the switching valve. Μβ The secondary object of the present invention is to provide a two-way hydraulic system of an operating table that uses a servo motor or a stepping motor to drive the rotating shaft to select a valve position, so that the bidirectional hydraulic pressure (four) device and the external oil are fine. The oil pressure path between the bits can be selected for switching. Another object of the present invention is to provide a design of a '_ σ bidirectional hydraulic system that can be installed in a thinner base, so that the valve block of the switching valve does not have any downward facing oil hole shaft and the rotating shaft can be located not in the valve. The center position of the block and the distance between the shaft hole and the rotating shaft, and the bottom surface of the valve block can be shortened, so that the total height of the switching valve can be

A further object of the present invention is to provide a two-way hydraulic system of the operating table, which is to switch the county to drive the drive _, and the valve-side device group is at the end of the control shaft _ alignment Each detection of the device corresponds to the side sensor of the individual sensing, and the oil pressure path between the rotating shaft and the external oil valve position is adjusted. Another object of the present invention is to provide a two-way hydraulic system of an operating table, such that the switching valve is provided with a knob that can be rotated from the outside of the base on the rotating shaft, and can be used as a switching valve when the motor cannot function. Manual operation of the handle. A further object of the present invention is to provide a double-sided hydraulic system for the operating table. The 201043215 can be fixed to the base and designed to reduce the cost of the switching valve without the need for additional sheet metal parts. [Embodiment] The structural features and other functions and purposes of the present invention are described in detail. Referring to Figures - 2 and 2, the bidirectional device of the operating table of the present invention is placed in the base of the operating table - a bi-directional hydraulic pumping device.

When the motor is stopped, there is a so-called inertial motion, and the rotation angle of the tilting shaft 2 2 cannot be used. Accurate control, at the same time, the rotation angle of the rotating shaft 2 ^ will be different due to the manufacturing tolerance of the switching valve 2, so that the valve position device 24 can not accurately position the rotating shaft 2 2, so the present invention uses the general rotating shaft 2 2 when rotating It needs to be precisely controlled by the timing of adjustable length, and the side of the side is correctly aligned. ] Machine again. Since all the oil holes that need to be connected to the oil pipe of the switching valve 2 do not have any oil holes facing downwards in the valve block 21', the cutting _ 2 can be provided at the bottom of the valve block 2, and a solid locking hole 213 is provided (such as As shown in Figure 5, the switching valve 2 can be placed on the base through the keyhole 2 i 3_ without the need for additional sheet metal parts, which greatly reduces the cost of the sheet metal parts. In the red, the design of the two-way hydraulic system of the operating table can be reduced. It is indeed possible for the hand-operated table to pass the oil supply of the two-way hydraulic pump through the shredded and conductive unit to the selected valve position, and _ Switching to the operation from the base assembly does not require a higher cost of space, so that the overall thickness of the base can have enough space to reduce, so that the operating table lifting stroke can be increased, so it can be seen that the effect is improved, and its hand is also used It is the first innovation, _ in line with the requirements for patent acquisition. For this reason, it is invented according to the law (4), and it is requested that the bureau should give a detailed examination and grant a patent.
