Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 9 As shown, the present invention provides an operating table with an automatically pop-up armrest, comprising an operating table body 1, and further comprising:

[0043] A support assembly 5, the support assembly 5 is installed at the bottom of the operating table body 1;

[0044] Transmission assembly 4, the transmission assembly 4 is installed on the support assembly 5;

[0045] The armrest assembly 2 is connected to the transmission assembly 4;

[0046] A push rod assembly 3, which is arranged at the bottom of the operating table body 1;

[0047] The limiting assembly 6 is arranged on the push rod assembly 3 and is used to limit the armrest assembly 2 and the transmission assembly 4;

[0048] The transmission assembly 4 includes a docking rod 41, a second coil spring 413 is installed at both ends of the docking rod 41, a sleeve 411 is arranged outside the second coil spring 413, a rectangular rod 412 is fixedly installed at one end of the sleeve 411, and the rectangular rod 412 is arranged on the support assembly 5. A symmetrical limiting groove 42 is opened outside the docking rod 41, a support frame 43 is fixedly installed at both ends of the docking rod 41, and a hand rest assembly 2 is fixedly installed at one end of the support frame 43;

[0049] The limiting assembly 6 includes a support rod 61, and receiving frames 66 are fixedly mounted on both ends of the support rod 61, and a latch 68 is fixedly mounted on the inner wall of the receiving frame 66;

[0050] The docking rod 41 moves in the receiving frame 66, and the latch 68 is engaged with the inside of the limiting groove 42;

[0051] In the initial state, when the armrest assembly 2 is located at the bottom of the operating bed body 1, the rectangular rod 412 is arranged on the supporting assembly 5, the second coil spring 413 is in a tightened state, and the bayonet 68 is engaged in a limiting groove 42 to fix the armrest assembly 2 to the bottom of the operating bed body 1;

[0052] By pulling the support rod 61 downwards through the push rod assembly 3, the latch 68 moves downwards and out of the limiting groove 42, and the second coil spring 413 resets to drive the docking rod 41, the support frame 43 and the hand rest assembly 2 to rotate, so that the hand rest assembly 2 and the operating bed body 1 remain level.

[0053] In the initial state, the armrest assembly 2 is located at the bottom of the operating bed body 1, and the rectangular rod 412 is installed on the support assembly 5, and the second coil spring 413 is in a tensioned state. By pushing the push rod assembly 3, the support rod 61 and the receiving frame 66 are pulled down, and the latch 68 is separated from the inside of the limiting groove 42. At this time, the second coil spring 413 is reset to drive the docking rod 41, the support frame 43 and the armrest assembly 2 to rotate. The armrest assembly 2 will rotate 180 degrees to keep it horizontal with the operating bed body 1, and the patient's arm can be supported by the armrest assembly 2. The support rod 61 and the receiving frame 66 are reset to make the latch 68 engage with the inside of another limiting groove 42, and the armrest assembly 2 and the transmission assembly 4 are fixed to ensure the stability of the patient's arm support;

[0054] After the operation is completed, the push rod assembly 3 is pushed to drive the support rod 61 and the receiving frame 66 to move downward, and the pin 68 is disengaged from the limiting groove 42, so that the handrest assembly 2, the docking rod 41 and the support frame 43 can be pushed to rotate 180 degrees in the opposite direction, and the second coil spring 413 can be compressed, so that the handrest assembly 2 can be fixed to the bottom of the operating bed body 1 through the pin 68, so that the handrest assembly 2 can be automatically popped out for easy use, reducing the disassembly steps of the handrest assembly 2.

[0055] like Figure 5 and Fig. 9 As shown, the armrest assembly 2 includes an armrest body 21 fixed to one end of a support frame 43, a winding rod 23 is fixed inside the armrest body 21, a bandage 22 is wound around the outside of the winding rod 23, and first coil springs 24 for winding the bandage 22 are arranged at both ends of the winding rod 23.

[0056] The transmission assembly 4 drives the armrest body 21 to rotate 180 degrees and keep it horizontal with the operating bed body 1. The patient's arm is placed on the armrest body 21. One end of the bandage 22 is pulled to drive the winding rod 23 to rotate and compress the first coil spring 24, so that the bandage 22 can be pulled out of the armrest body 21. The patient's arm is fixed by the two bandages 22. After use, the bandage 22 is released, and the first coil spring 24 is reset to rewind the bandage 22 inside the armrest body 21.

[0057] like Figure 3 , Figure 5 and Figure 6 As shown, the push rod assembly 3 includes a limit frame 31 fixedly mounted on the bottom of the operating bed body 1, and a transmission rod 32 is movably sleeved on the limit frame 31;

[0058] The limiting assembly 6 further includes a guide rod 65 fixedly mounted on the limiting frame 31, and the support rod 61 and the limiting frame 31 are connected via a spring sheet 64;

[0059] A connecting frame 62 is fixedly mounted at the bottom of the supporting rod 61, and a limiting groove 63 is provided in the connecting frame 62;

[0060] The bottom of the limiting groove 63 is in the shape of a boss, and a groove matching the boss at the bottom of the limiting groove 63 is formed at the bottom of the middle part of the transmission rod 32 .

[0061] By pushing the transmission rod 32 to move horizontally under the action of the limit frame 31, the inner wall of the groove at the bottom of the transmission rod 32 cooperates with the outer wall of the boss in the limit groove 63, thereby pushing the support rod 61 to move downward along the guide rod 65 and compressing the spring 64. At this time, the receiving frame 66 and the pin 68 move downward to make the pin 68 disengage from the inside of the limit groove 42. After the rotation of the transmission assembly 4 and the hand rest assembly 2 is completed, the boss at the bottom of the transmission rod 32 resets the limit groove 63 and engages in the groove at the bottom of the transmission rod 32, so that the reset pin 68 of the limit assembly 6 engages in the limit groove 42 to limit the transmission assembly 4 and the hand rest assembly 2.

[0062] like Figure 3 , Figure 4 and Figure 6 As shown, the transmission assembly 4 further includes a slide groove 44 provided on the support frame 43, a slide frame 45 slides inside the slide groove 44, and a limit plate 46 is fixed on the slide frame 45;

[0063] The limiting assembly 6 also includes stabilizing grooves 69 provided at both ends of the receiving frame 66;

[0064] When the limiting plate 46 is in a vertical state, it remains vertical with the stabilizing groove 69 .

[0065] By pushing the push rod assembly 3, the limit assembly 6 is driven to break away from the limit of the transmission assembly 4 and the operating bed body 1. At this time, the second coil spring 413 is reset to drive the docking rod 41, the support frame 43 and the hand rest assembly 2 to rotate 180 degrees. When the support frame 43 is initially in a vertical state, the limit plate 46 and the sliding frame 45 move down along the slide groove 44 under the action of their own weight. The limit plate 46 will be engaged with the inside of the stable groove 69. The limit plate 46 cooperates with the stable groove 69 to improve the stability of the transmission assembly 4 and the hand rest assembly 2, thereby preventing the patient's arm from rotating when placed on the hand rest assembly 2.

[0066] When the armrest assembly 2 needs to be folded, the sliding frame 45 is lifted up, and the limit plate 46 is separated from the inside of the stabilizing groove 69, so that the push rod assembly 3 can be pushed to make the limit assembly 6 separate from the limit of the docking rod 41, and the armrest assembly 2 can be rotated to the bottom of the operating bed body 1.

[0067] like Figure 7 and Figure 8 As shown, the support assembly 5 includes a fixing frame 51 fixed to the bottom of the operating bed body 1, a transverse groove is provided on the top of the fixing frame 51, and the rectangular rod 412 is placed in the transverse groove. A guide rail 53 is installed on the top of the fixing frame 51, and a block 55 is slidably provided on the outside of the guide rail 53;

[0068] The rectangular rod 412 is located between the clamping block 55 and the fixing frame 51;

[0069] A spring telescopic rod 54 is installed on the fixing frame 51, and a limit block 52 is fixed on the top of the spring telescopic rod 54;

[0070] The limit block 52 and the guide rail 53 are pressed down to form a complete guide rail, and the clamping block 55 can slide along the guide rail 53 and the limit block 52 to be separated from the top of the rectangular rod 412.

[0071] By placing the rectangular rod 412 on the fixing frame 51, pushing the block 55 to slide along the guide rail 53 and the limit block 52 to the top of the rectangular rod 412, the rectangular rod 412 is fixed between the fixing frame 51 and the block 55, and the limit block 52 moves upward under the action of the spring telescopic rod 54 to limit the block 55, so that the transmission assembly 4 can be fixed on the fixing frame 51;

[0072] When the transmission assembly 4 and the armrest assembly 2 need to be removed, the limit block 52 and the guide rail 53 are pressed down to form a complete track, and the clamping block 55 can be pushed in the reverse direction to disengage from the top of the rectangular rod 412, so that the transmission assembly 4 and the armrest assembly 2 can be removed for replacement or cleaning and disinfection.

[0073] The working principle and use process of the present invention:

[0074] Place the rectangular rod 412 on the fixing frame 51 and push the block 55 to slide along the guide rail 53 and the limit block 52 to the top of the rectangular rod 412, fix the rectangular rod 412 between the fixing frame 51 and the block 55, and at the same time, the limit block 52 moves upward under the action of the spring telescopic rod 54 to limit the block 55, so that the transmission assembly 4 can be fixed on the fixing frame 51;

[0075] In the initial state, the armrest assembly 2 is located at the bottom of the operating bed body 1, and the rectangular rod 412 is installed on the support assembly 5, and the second coil spring 413 is in a tensioned state. By pushing the transmission rod 32 to move horizontally under the action of the limiting frame 31, the inner wall of the groove at the bottom of the transmission rod 32 cooperates with the outer wall of the boss in the limiting groove 63, thereby pushing the support rod 61 to move downward along the guide rod 65 and compressing the spring piece 64. At this time, the receiving frame 66 and the bayonet 68 move downward to disengage the bayonet 68 from the inside of the limiting groove 42. The second coil spring 413 loses the limit reset and drives the docking rod 41, the support frame 43 and the hand rest frame assembly 2 to rotate, and the hand rest frame assembly 2 will rotate 180 degrees to keep it level with the operating bed body 1, so that the patient's arm can be supported by the hand rest frame assembly 2, and the boss at the bottom of the reset limit groove 63 of the transmission rod 32 is engaged in the groove at the bottom of the transmission rod 32, so that the reset latch 68 of the limit assembly 6 is engaged in the limit groove 42 to limit the transmission assembly 4 and the hand rest frame assembly 2, thereby ensuring the stability of the support for the patient's arm;

[0076] During the rotation of the support frame 43, the limit plate 46 and the sliding frame 45 move downward along the slide groove 44 under the action of their own weight, and the limit plate 46 is engaged with the inside of the stable groove 69. The limit plate 46 cooperates with the stable groove 69 to improve the stability of the transmission assembly 4 and the hand rest assembly 2, thereby preventing the patient's arm from rotating when placed on the hand rest assembly 2.

[0077] When the patient's arm is placed on the armrest body 21, one end of the bandage 22 is pulled to drive the reeling rod 23 to rotate and compress the first coil spring 24, so that the bandage 22 can be pulled out of the armrest body 21, and the patient's arm is fixed by the two bandages 22. After use, the bandage 22 is released, and the first coil spring 24 is reset to reel the bandage 22 inside the armrest body 21;

[0078] After the operation is completed, the sliding frame 45 is lifted up, the limiting plate 46 is separated from the inside of the stable groove 69, the push rod assembly 3 is pushed to drive the support rod 61 and the receiving frame 66 to move downward, and the latch 68 is separated from the inside of the limiting groove 42, so that the hand rest frame assembly 2, the docking rod 41 and the support frame 43 can be pushed to rotate 180 degrees in the opposite direction, and the second coil spring 413 is in a tight state, and the hand rest frame assembly 2 can be fixed to the bottom of the operating bed body 1 through the latch 68, and the above steps can be repeated in sequence to realize the automatic pop-up of the hand rest frame assembly 2 for easy use;

[0079] When the transmission assembly 4 and the armrest assembly 2 need to be removed, the limit block 52 and the guide rail 53 are pressed down to form a complete track, and the clamping block 55 can be pushed in the reverse direction to disengage from the top of the rectangular rod 412, so that the transmission assembly 4 and the armrest assembly 2 can be removed for replacement or cleaning and disinfection.
