A column is fixedly installed in the middle of the top of the support seat, a fixing mechanism is provided on the column, a locking mechanism is provided on the top of the column, and the syringe body is arranged on the column through the locking mechanism; the fixing mechanism includes a chamber, the chamber is opened in the column, the chamber is close to the support seat, a slide groove connected to the chamber is opened on one side of the column, a push plate is slidably connected between the slide groove and the chamber, and one end of the push plate passes through the slide groove.

[0004] Most of the existing high-pressure injectors have simple structures and are not convenient to connect with the examination bed. When the examination bed needs to be moved to drive the patient to move, the high-pressure injector needs to be moved separately, which is troublesome to move. It is also easy to pull the injection tube when moving separately, which is not safe. At the same time, the high-pressure injector is not convenient to store, which increases the occupied space when moving. Therefore, in view of the above technical problems, a high-pressure injector is proposed. Summary of the invention

[0007] A column, the top of which is provided with a high-pressure injector body, the bottom of which is hinged with a plurality of support rods along its circumference, and the bottoms of the plurality of support rods are all provided with universal wheels with a self-locking function;

[0008] The clamping mechanism comprises a fixed clamping plate and a movable clamping plate, wherein the fixed clamping plate is arranged on the peripheral side of the column, the movable clamping plate is located below the fixed clamping plate and has a first connecting sleeve arranged at one end, the first connecting sleeve is sleeved on the column and can slide along the axial direction thereof; and

[0009] The driving mechanism includes a motor, a turntable and a transmission assembly, wherein the motor is arranged on the column, and the output end is coaxially connected to the turntable, and the transmission assembly is connected to the first connecting sleeve, the turntable and the multiple groups of support rods. The forward rotation of the turntable can first drive the movable splint to move upward to a preset position through the transmission assembly and then keep it stationary, and then drive the multiple groups of support rods to close and rotate upward. The reverse rotation of the turntable can first drive the multiple groups of support rods to open and rotate downward through the transmission assembly and then reset, and then drive the movable splint to move downward.

When the first connection sleeve 202 moves upward, the linkage assembly can drive the rotating shaft 405 to rotate forward, so that the storage box 40 extends out of the placement slot 103. When the first connection sleeve 202 moves downward, the linkage assembly can drive the rotating shaft 405 to rotate reversely, so that the storage box 40 is retracted into the placement slot 103. Specifically, the linkage assembly includes a gear 406 and a rack 407; the gear 406 is coaxially arranged at one end of the rotating shaft 405, and the rack 407 is arranged on the first connection sleeve 202 and meshes with the gear 406.

[0059] In the above embodiment, when the first connecting sleeve 202 drives the movable splint 201 to move upward to clamp the bed board 2, the first connecting sleeve 202 drives the rack 407 to move upward, and the rack 407 moves upward to engage with the gear 406 to drive the gear 406 to rotate forward, and the gear 406 rotates forward to drive the rotating shaft 405 to rotate forward, so that the storage box 40 extends out of the placement slot 103, so that the storage box 40 is automatically extended out of the placement slot 103 when the device is connected to the examination bed. When the first connecting sleeve 202 drives the movable splint 201 to move downward to cancel the clamping of the bed board 2, the first connecting sleeve 202 moves downward to drive the rack 407 to move downward, and the rack 407 moves downward to engage with the gear 406 to drive the gear 406 to reverse, and the gear 406 reverses to drive the rotating shaft 405 to reverse, so that the storage box 40 is retracted into the placement slot 103, so that the storage box 40 is automatically stored in the placement slot 103 when the device is separated from the examination bed.

[0060] The specific implementation of the above-mentioned high-pressure injector is as follows:

[0061] When the examination bed needs to be moved to drive the patient to move, the device is first moved to one side of the examination bed and the fixed splint 20 is in contact with the top surface of the bed board 2, and the movable splint 201 is located below the bed board 2. Then the motor 30 is controlled to drive the turntable 301 to rotate forward, and the turntable 301 rotates forward to drive the inclined groove 3011 and the positioning ring groove 3012 to rotate. The inclined groove 3011 rotates to squeeze the dial shaft 3021 to move upward, and the dial shaft 3021 moves upward to drive the first connecting sleeve 202 through the connecting column 302 to drive the movable splint 201 to move upward. When the movable splint 201 moves upward and abuts against the bottom surface of the bed board 2 and cooperates with the fixed splint 20 to clamp the bed board 2, the shift shaft 3021 slides from the inclined groove 3011 to the positioning ring groove 3012. The positioning ring groove 3012 can be rotated to fix the shift shaft 3021, thereby fixing the movable splint 201, and then fixing the device on the examination bed. The device is easy to connect to the examination bed and can be driven to move by moving the examination bed. There is no need to move the device separately to avoid pulling the injection tube. The movement is convenient and safe.

[0062] When the lever shaft 3021 slides from the inclined groove 3011 to the positioning ring groove 3012, the bevel gear 305 meshes with the bevel gear arc segment 306. At this time, the turntable 301 rotates forward to drive the bevel gear arc segment 306 to rotate and cooperate with the bevel gear 305 to drive the first screw rod 304 to rotate. The first screw rod 304 rotates and cooperates with the second connecting sleeve 303 threadedly to drive the second connecting sleeve 303 to move upward. The second connecting sleeve 303 moves upward and drives the multiple groups of support rods 101 to close and rotate upward through the multiple groups of connecting rods 3031. It is convenient to fold the multiple groups of support rods 101, thereby reducing the occupied space of the device, and further reducing the occupied space when the device is moved. The multiple groups of support rods 101 can be automatically folded after the device is connected to the examination bed, further improving the convenience of the device. At the same time, the upward folding movement of the multiple groups of support rods 101 can drive the multiple groups of universal wheels 102 to separate from the ground, that is, when the device moves with the bed, the universal wheels 102 do not work, thereby increasing the service life of the universal wheels 102.

[0063] When the device needs to be separated from the examination bed, the motor 30 is controlled to drive the turntable 301 to reverse, and the turntable 301 reverses to drive the bevel gear arc segment 306 to rotate in the opposite direction and cooperate with the bevel gear 305 to drive the first screw rod 304 to rotate in the opposite direction. The first screw rod 304 rotates in the opposite direction and cooperates with the second connecting sleeve 303 thread to drive the second connecting sleeve 303 to move downward. The downward movement of the second connecting sleeve 303 can drive the multiple groups of support rods 101 to open and rotate downward through the multiple groups of connecting rods 3031, and make the multiple groups of universal wheels 102 contact with the ground, thereby resetting the multiple groups of support rods. Rod 101, and after the multiple groups of support rods 101 are reset, the bevel gear arc segment 306 is separated from the bevel gear 305, and the shift shaft 3021 slides from the positioning ring groove 3012 to the inclined groove 3011. At this time, the turntable 301 reverses and drives the shift shaft 3021 to move downward through the inclined groove 3011. The shift shaft 3021 moves downward and drives the first connecting sleeve 202 through the connecting column 302 to drive the movable splint 201 to move downward. The movable splint 201 moves downward and can be separated from the bottom surface of the bed board 2, thereby canceling the connection between the device and the examination bed, which is convenient for canceling the connection between the device and the examination bed.
