[0006] Preferably, the support structure further includes a connecting groove, which is formed inside the connecting block. The bottom surface of the connecting groove has a rectangular groove, and multiple sets of rectangular grooves are provided. A first support rod is inserted inside the connecting groove, and a second support rod is connected to one end of the first support rod by a bearing. A threaded rod is threadedly connected to the bottom surface of one side of the support base, and a clamping plate is connected to the upper end surface of the threaded rod by a bearing. This design allows the clamping plate to move inside the support base by rotating the threaded rod.

[0007] Preferably, a cylindrical block is fixedly connected to the bottom of the other end of the first support rod, and rectangular blocks are fixedly connected to both sides of the cylindrical block. The external dimensions of the rectangular blocks are adapted to the internal dimensions of the rectangular groove. This design makes the rectangular blocks more stable when inserted into the rectangular groove.

[0008] Preferably, hinged columns are fixedly connected to both sides of one end of the third support rod, and a positioning rod is inserted inside the hinged column. A first spring is fixedly connected to one end of the positioning rod. A hinged block is hinged to the outer surface of the hinged column, and an arm support base is fixedly connected to the top surface of the hinged block. An extended arm support is attached to both sides of the arm support base. Telescopic grooves are opened inside both ends of the arm support base, and rectangular slides are inserted inside the telescopic grooves. A positioning slot is opened on the bottom surface of the rectangular slide. One end of the rectangular slide is fixedly connected to the outer surface of one side of the extended arm support. Operating blocks are inserted inside both ends of the arm support base, and a second spring is fixedly connected to the bottom surface of the operating blocks. This design allows the rectangular slide to move inside the telescopic groove.

By pushing the four sets of operating blocks downwards, the positioning block at the top of the operating block disengages from the positioning slot. Then, the two sets of extended arm supports are pulled according to actual needs to adapt to the patient's arm length. After the two sets of extended arm supports move to the appropriate position, the operating blocks are released, allowing the operating blocks to automatically reset due to the elasticity of the second spring. At the same time, the positioning block at the top of the operating block inserts into the corresponding positioning slot. This makes the device easy to adjust according to the arm length of different patients, improving its applicability to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

The patient examination armrest involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1 like Figures 1-3 As shown, this embodiment proposes a patient examination armrest, comprising: Support base 1, with a support structure 2 at the upper end of support base 1, and an adjustment structure 3 at the upper end of support structure 2; The support structure 2 includes a connecting block 21 and a second support rod 25, and the connecting block 21 is fixedly connected to the outer surface of one side of the support base 1; The support structure 2 also includes a connecting groove 22, which is opened inside the connecting block 21. A rectangular groove 23 is opened on the bottom surface of the connecting groove 22, and multiple sets of rectangular grooves 23 are provided. A first support rod 24 is inserted inside the connecting groove 22, and a second support rod 25 is connected to one end of the first support rod 24 by a bearing. A threaded rod 26 is threadedly connected to the bottom surface of one side of the support base 1, and a clamping plate 27 is connected to the upper end surface of the threaded rod 26 by a bearing. A cylindrical block is fixedly connected to the bottom of the other end of the first support rod 24, and rectangular blocks are fixedly connected to both sides of the cylindrical block. The external dimensions of the rectangular blocks are adapted to the internal dimensions of the rectangular groove 23. In this embodiment, the design makes the first support rod 24 more stable when rotating inside the connecting groove 22, and the position of the first support rod 24 can be positioned by inserting a rectangular block inside the rectangular groove 23.

[0021] Example 2 like Figures 4-6 As shown, based on the same concept as the above embodiments, this embodiment also proposes: The adjustment structure 3 includes a third support rod 31, and the third support rod 31 is inserted into the interior of one end of the second support rod 25; The third support rod 31 has hinged columns fixedly connected to both sides at one end, and a positioning rod 32 is inserted inside the hinged column. A first spring 33 is fixedly connected to one end of the positioning rod 32. A hinge block 34 is hingedly connected to the outer surface of the hinged column, and an arm support base 35 is fixedly connected to the top surface of the hinge block 34. An extended arm support 36 is attached to both sides of the arm support base 35. Telescopic grooves are opened inside both ends of the arm support base 35, and rectangular slide bars 37 are inserted inside the telescopic grooves. A positioning slot is opened on the bottom surface of the rectangular slide bar 37. One end of the rectangular slide bar 37 is fixedly connected to the outer surface of one side of the extended arm support 36. An operating block 38 is inserted inside both ends of the arm support base 35, and a second spring 39 is fixedly connected to the bottom surface of the operating block 38. The hinge column has through slots on both sides, and the positioning rod 32 has locking blocks fixedly connected to both sides. The outer surface of the locking blocks is inserted into the through slots. The hinge block 34 has a rotating slot at one end, and a positioning slot is formed on the inner wall surface of one side of the rotating slot. The outer dimensions of the locking block are matched with the inner dimensions of the positioning slot. This design makes the locking block more stable when it moves inside the through slot, and it is more stable when the locking block is inserted into the positioning slot. A limiting plate is provided at one end of the rectangular slide bar 37, and the external dimensions of the limiting plate are adapted to the internal dimensions of the telescopic groove. A positioning block is fixedly connected to the upper end of the operating block 38, and the external dimensions of the positioning block are adapted to the internal dimensions of the positioning slot. This design ensures that the rectangular slide bar 37 will not detach from the telescopic groove when it moves inside the telescopic groove, and the positioning block is more stable when inserted into the positioning slot.

[0022] Working Principle: When using the equipment, first place it in a suitable position, rotate the threaded rod 26 to move the clamping plate 27 upward inside the support base 1, and position the support base 1. Then lift the first support rod 24 upward, so that the rectangular blocks on both sides of the bottom cylindrical block of the first support rod 24 disengage from the rectangular groove 23. Then, the position of the arm support base 35 can be adjusted by the cooperation of the first support rod 24, the second support rod 25 and the third support rod 31. After the arm support base 35 moves to the desired position, lower the first support rod 24 so that the rectangular block inserts into the rectangular groove 23 at the corresponding position, and position the first support rod 24. When it is necessary to adjust the angle of the arm support base 35, the positioning rod 32 can be pushed inward, so that the locking block at one end of the positioning rod 32 moves from the inside of the positioning groove to the inside of the rotating groove. At this time, the hinge block can be rotated. 34 synchronously drives the arm support base 35 to rotate. After the arm support base 35 is adjusted to the required angle, the positioning rod 32 can be released. The elasticity of the first spring 33 causes the locking block to insert into the corresponding positioning groove. When the patient's arm length is greater than the length of the arm support base 35, the four sets of operating blocks 38 can be pulled down, and the two sets of extended arm supports 36 can be pulled outward. At the same time, the four sets of rectangular slide bars 37 move synchronously inside the telescopic groove. When the extended arm support 36 is extended to the required length, the four sets of operating blocks 38 can be released, allowing the operating blocks 38 to reset themselves through the elasticity of the second spring 39. The positioning block at the upper end of the operating block 38 inserts into the corresponding positioning groove at the bottom of the rectangular slide bar 37, thus facilitating the adjustment of the device's position and angle according to actual needs. The above is the complete working principle of this utility model.
