[0037] Please refer to Figure 1 , the fixer provided by the embodiment of the present application will be described. The fixer is used to install accessories on the guide rail of the operating bed, wherein the accessories can be operating accessories such as hand support, foot support, body support and shoulder support. It can be understood that in other embodiments of the present application, the fixer can also install other accessories on the main body, such as installing mechanical accessories on a machine tool, or installing nursing accessories on a nursing bed, etc., which is not limited here.

[0038] For the convenience of description, the main body hereinafter is directly replaced by the operating bed, wherein the operating bed includes a guide rail, and the fixer is installed on the guide rail.

[0039] Please refer to Figure 1 and Figure 2 , the fixer includes a mounting seat 1, a locking mechanism 2 and a clamping mechanism 3. The mounting seat 1 is formed with a mounting hole 11 for mounting the accessory; the clamping mechanism 3 is movably installed on the mounting seat 1; the locking mechanism 2 is provided on the mounting seat 1, the locking mechanism 2 is connected with the clamping mechanism 3, the locking mechanism 2 is used to drive the clamping mechanism 3 to clamp the main body, and the locking mechanism 2 can clamp the main body while driving the clamping mechanism 3 to clamp the main body, so as to fix the accessory on the mounting seat 1.

[0040] When the accessory needs to be installed on the operating bed, the accessory is first threaded into the mounting hole 11, then the clamping mechanism 3 is clamped on the guide rail of the operating bed, and finally the locking mechanism 2 is driven to drive the clamping mechanism 3 to clamp the guide rail of the operating bed, and at the same time the locking mechanism 2 abuts against the surface of the accessory, so that the accessory is fixed on the mounting seat 1, thereby realizing the installation of the accessory on the operating bed.

[0041] The fixture in this embodiment can install the accessory through the mounting hole 11, and can also be clamped on the guide rail of the operating bed through the clamping mechanism 3, thereby realizing the installation of the accessory on the operating bed. At the same time, the locking mechanism 2 is connected with the clamping mechanism 3 and the accessory respectively, and the locking mechanism 2 can drive the clamping mechanism 3 to clamp the clamping mechanism 3 on the guide rail of the operating bed, and at the same time the locking mechanism 2 can also abut against the accessory to fix the accessory on the mounting seat 1, that is, through one locking mechanism 2, the installation of the fixture on the operating bed and the installation of the accessory on the fixture can be realized at the same time, and only one driving needs to be performed, so that the assembly process of the accessory on the operating bed is simple and the assembly efficiency is high. In addition, the fixture is clamped on the guide rail of the operating bed through the clamping mechanism 3, so that the fixture can be used not only for fixing on the guide rail of the operating bed in the non-sterile area, but also for clamping on the guide rail of the operating bed covered with a sterile operating bed sheet through the clamping mechanism 3, so that the fixture can be used for fixing the accessory in the non-sterile area, and also for fixing the accessory that needs to be treated in a sterile manner, and the application range is wide, which is convenient for doctors to use.

[0042] In one embodiment, please refer to Figures 1 to 5 The locking mechanism 2 includes a driving member 21, a first driven member 22 and a second driven member 23. The driving member 21 is movably arranged on the mounting seat 1, and the driving member 21 can be driven to rotate. The first driven member 22 is connected with the driving member 21, and the first driven member 22 is connected with the clamping mechanism 3. When the driving member 21 is driven to rotate, the first driven member 22 can be driven by the driving member 21 to move linearly to drive the clamping mechanism 3 to clamp the main body. The second driven member 23 is connected with the driving member 21, and when the driving member 21 is driven to rotate, the second driven member 23 can be driven by the driving member 21 to move linearly to abut the accessory in the mounting hole 11.

[0043] When the accessory is threaded into the mounting hole 11 and the clamping mechanism 3 is clamped on both sides of the guide rail, only the driving member 21 needs to be driven to rotate, which can simultaneously drive the first driven member 22 and the second driven member 23 to move linearly, so that the clamping mechanism 3 clamps the guide rail and the second driven member 23 abuts the accessory in the mounting hole 11. The overall assembly operation is simple, and only the driving member 21 needs to be driven to rotate. Specifically, the driving member 21 can be manually, externally or electrically driven to rotate.

[0044] In one embodiment, referring to Figures 1 to 4 , the driving member 21 is threadedly sleeved on the first driven member 22, and the second driven member 23 is in abutting contact with the driving member 21; when the driving member 21 is driven to rotate, the driving member 21 can move along the first driven member 22 in the positive axial direction to push the second driven member 23 to move to abut against the accessory; when the driving member 21 rotates, the first driven member 22 can move along the first driven member 22 in the negative axial direction to drive the clamping mechanism 3 to clamp the body.

[0045] Wherein, since the driving member 21 and the first driven member 22 are threadedly connected, when the driving member 21 is driven to rotate, the driving member 21 moves on the first driven member 22 in a spiral motion, that is, the driving member 21 rotates on the first driven member 22 and the driving member 21 moves along the first driven member 22 in the positive axial direction. Since the first driven member 22 is threadedly connected with the driving member 21, the first driven member 22 will be driven by the driving member 21 to move in the opposite direction, and here, in order to distinguish, the driving member 21 moves along the first driven member 22 in the positive axial direction, and the first driven member 22 moves along the first driven member 22 in the negative axial direction. In summary, in this embodiment, the driving member 21 and the first driven member 22 threadedly connected can form opposite linear motions, so that the driving member 21 can drive the first driven member 22 and the second driven member 23 to move in opposite directions at the same time, and thus one driving can simultaneously achieve clamping of the clamping mechanism 3 and abutting of the accessory. It can be understood that in other embodiments of the present application, the above-mentioned driving member 21, first driven member 22 and second driven member 23 can also be connected in other ways, for example, the driving member 21 is a gear, the first driven member 22 and the second driven member 23 are both racks; or the driving member 21 is a cam, the first driven member 22 and the second driven member 23 are both needle bars in abutting contact with the cam at different positions, and the cam can drive the two needle bars to move respectively when it rotates, which is not limited here.

[0046] In one embodiment, referring to Figures 1 to 3 , the driving member 21 is a nut threadedly sleeved on the first driven member 22, and the locking mechanism 2 further comprises a handle 24, the handle 24 is fixedly connected with the nut, so that the nut can be driven to rotate by pulling the handle 24, that is, the locking of the accessory and the clamping of the clamping mechanism 3 to the guide rail can be achieved only by pulling the handle 24, which is simple and labor-saving.

[0047] Referring to Figure 3 , the handle 24 comprises a connecting portion 241 and a handle portion 242, the connecting portion 241 is fixedly connected with the nut, and the handle portion 242 extends outwardly from the connecting portion 241. The length of the handle portion 242 can be set as needed, so that the handle portion 242 is as long as possible without occupying too much space, thereby achieving the effect of saving labor.

[0048] Please refer to Figure 3 The connecting part 241 is U-shaped and sleeved on the nut, and opposite ends of the connecting part 241 are fixedly connected with the nut through the fixing pins.

[0049] In an embodiment, please refer to Figure 1 The mounting hole 11 penetrates through opposite sides of the mounting base 1, and during installation, the accessory is inserted into the mounting hole 11 and locked through the locking mechanism 2. The axial direction of the mounting hole 11 is perpendicular to the axial direction of the first driven part 22.

[0050] The shape of the mounting hole 11 can be set according to the actual shape of the accessory, for example, it can be circular, square or other shapes.

[0051] In an embodiment, please refer to Figures 2 to 5 The locking mechanism 2 further includes a first reset part 25, which is arranged in the mounting base 1, and opposite ends of the first reset part 25 are connected with the mounting base 1 and the first driven part 22 and are used for resetting the first driven part 22. In this embodiment, since the first driven part 22 is in threaded transmission connection with the driving part 21, taking the case that the driving part 21 rotates forward and moves downward and drives the first driven part 22 to move upward as an example, when the driving part 21 reversely rotates and resets, the first driving part 21 will not move downward to reset, and at this time, the first reset part 25 can drive the first driven part 22 to reset downward to the initial state.

[0052] Similarly, please refer to Figure 2 and Figure 3 The locking mechanism 2 further includes a second reset part 26, which is arranged in the mounting base 1, and opposite ends of the second reset part 26 are connected with the mounting base 1 and the second driven part 23 and are used for resetting the second driven part 23. The second driven part 23 is in abutting contact with the lower side of the driving part 21, and when the driving part 21 moves downward, the second driven part 23 can be pushed to move downward to abut against the accessory; when the driving part 21 moves upward to reset, the driving part 21 is separated from the second driven part 23, and the second driven part 23 cannot move upward to reset, and at this time, the second reset part 26 can drive the second driven part 23 to reset to the initial state.

[0053] Please refer to Figure 4 The first driven part 22 is rod-shaped, the mounting base 1 is provided with a center hole 12 penetrating through the upper and lower sides, the first driven part 22 is inserted into the center hole 12, the top end of the first driven part 22 is in threaded transmission cooperation with the driving part 21, the clamping mechanism 3 is installed at the bottom end of the first driven part 22, and the first reset part 25 can be a first spring, which is sleeved on the first driven part 22 and is in abutting contact between the first driven part 22 and the mounting base 1; please refer to Figure 3, the second reset member 26 can be a second spring, the second spring abuts between the second driven member 23 and the mounting base 1. When it is needed to install the accessory on the rail, the driving member 21 is rotated forward, the driving member 21 moves downward and pushes the second driven member 23 to move downward to abut against the accessory, at the same time, the first driven member 22 moves upward under the driving of the driving member 21 to drive the clamping mechanism 3 to clamp the rail of the operating table, and the first reset member 25 and the second reset member 26 are compressed and accumulate elastic force; when it is needed to disassemble the accessory and the rail, the driving member 21 is rotated reversely, the driving member 21 moves upward to reset, the first driven member 22 moves downward under the elastic action of the first reset member 25 to drive the clamping mechanism 3 to unfold and release the rail, at the same time, the second driven member 23 moves upward to reset and releases the accessory under the elastic action of the second reset member 26, so that the separation of the accessory and the rail is realized.

[0054] Please refer to Figure 4 , the inner wall of the center hole 12 is formed with a first step 121, the bottom end of the first driven member 22 is formed with a second step 221, the first reset member 25 abuts between the first step 121 and the second step 221, when the first reset member 25 is stretched, the first driven member 22 moves downward under the driving of the first reset member 25.

[0055] In an embodiment, please refer to Figure 3 、 Figure 4 and Figure 6 , the mounting base 1 is provided with a receiving groove 15 and a first mounting groove 16, the first mounting groove 16 is arranged in a spaced manner with the mounting hole 11, the receiving groove 15 is communicated with the first mounting groove 16 and the mounting hole 11 respectively, the second driven member 23 is in a plate shape and is received in the receiving groove 15, and the second reset member 26 is received in the first mounting groove 16.

[0056] Specifically, the receiving groove 15 is arranged above the mounting hole 11 and the first mounting groove 16, during assembly, the second driven member 23 and the second reset member 26 are respectively installed in the receiving groove 15 and the first mounting groove 16; when the accessory is installed, the accessory is transversely arranged in the mounting hole 11, then the second driven member 23 is driven downward by the driving member 21 to abut against the outer wall of the accessory, so that the installation of the accessory is realized. When it is needed to disassemble the accessory, the driving member 21 is reversely rotated, then the second driven member 23 is pushed upward by the second reset member 26, so that the second driven member 23 releases the accessory, and the accessory can be disassembled.

[0057] In the embodiment, since the first follower 22 is in threaded transmission cooperation with the driving member 21, and the clamping mechanism 3 is installed on the first follower 22, in order to ensure the structural balance and stability of the entire fixture, the first follower 22 needs to be installed at the center position of the mounting seat 1, and the mounting hole 11 is arranged beside the center hole 12, and in order to ensure the resetting effect of the second resetting member 26 on the second follower 23, the second resetting member 26 is generally arranged beside the mounting hole 11, for example Figure 3 In the embodiment, the center hole 12, the mounting hole 11 and the first mounting groove 16 are sequentially arranged. Since the size of the accessory is large, the size of the mounting hole 11 is large, in order to reduce the length of the entire mounting seat 1, the locking mechanism 2 further comprises an extension rod 27, the extension rod 27 abuts between the second resetting member 26 and the second follower 23, the extension rod 27 is in the form of a rod and is used to increase the distance between the second resetting member 26 and the second follower 23.

[0058] Specifically, the first mounting groove 16 is arranged in a stepped manner, the first mounting groove 16 comprises a small-diameter section 161 and a large-diameter section 162, the diameter of the large-diameter section 162 is larger than that of the small-diameter section 161, the small-diameter section 161 is connected between the large-diameter section 162 and the receiving groove 15, and the small-diameter section 161 is arranged beside the mounting hole 11. The diameter of the extension rod 27 is smaller than that of the second resetting member 26, the extension rod 27 is accommodated in the small-diameter section 161, and the second resetting member 26 is accommodated in the large-diameter section 162. In this way, the resetting effect of the second resetting member 26 on the second follower 23 can be achieved, and the occupied space beside the mounting hole 11 can be reduced.

[0059] The bottom end of the extension rod 27 is provided with a stop plate (not labeled in the figure), which is used to abut against the top side wall of the large-diameter section 162 to limit the upward movement of the extension rod 27.

[0060] Please refer to Figure 3 The bottom of the mounting seat 1 is provided with a second mounting groove corresponding to the position of the large-diameter section 162, which is used to realize the installation of the second resetting member 26 and the extension rod 27. The second mounting groove is provided with a cover plate 4, which is used to prevent the second resetting member 26 and the extension rod 27 from falling out.

[0061] In one embodiment, please refer to Figure 4The mounting base 1 is provided with a center hole 12, and the first follower 22 is slidably arranged in the center hole 12. The locking mechanism 2 further comprises a limiting structure 28 connected between the first follower 22 and the mounting base 1, and the limiting structure 28 is used to limit the sliding stroke of the first follower 22. In the embodiment, the first follower 22 is in sliding fit with the mounting base 1, and the mounting base 1 does not axially limit the first follower 22. The first return member 25 is used to drive the first follower 22 to return downward. In order to avoid the first follower 22 from unlimitedly moving downward under the action of the first return member 25 and gravity, the locking mechanism 2 further comprises the limiting structure 28, which limits the sliding of the first follower 22, so that the sliding stroke of the first follower 22 is equal to the sliding stroke of the driving member 21 in reverse, thereby ensuring that the locking mechanism 2 can always repeat.

[0062] In one specific embodiment, please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 7 The limiting structure 28 comprises a limiting rod 281 and a limiting groove 282. The limiting rod 281 is fixed on the mounting base 1. The limiting groove 282 is formed on the first follower 22 and extends along the axial direction of the first follower 22. The limiting rod 281 is in sliding fit with the limiting groove 282. Specifically, the limiting rod 281 slides between the opposite ends of the limiting groove 282 during the lifting of the first follower 22 in the center hole 12, thereby limiting the sliding stroke of the first follower 22.

[0063] Please refer to Figure 4 The limiting rod 281 transversely penetrates the center hole 12 and is fixed at the opposite ends in the mounting base 1. The middle part of the limiting rod 281 penetrates the limiting groove 282 and is limited to slide between the opposite ends of the limiting groove 282.

[0064] It can be understood that in other embodiments of the present application, the limiting rod 281 can be fixed on the first follower 22, and the limiting groove 282 can be formed in the mounting base 1, which can also limit the sliding of the first follower 22. That is, the limiting rod 281 is fixed on one of the first follower 22 and the mounting base 1, and the limiting groove 282 is formed in the other one, which is not limited.

[0065] In one embodiment, please refer to Figure 5The clamping mechanism 3 comprises two clamping blocks 31 symmetrically arranged on opposite sides of the first follower 22. The clamping block 31 is rotatably arranged on the mounting seat 1, and one end of the clamping block 31 is connected with the first follower 22. The first follower 22 is movable to drive the two clamping blocks 31 to rotate synchronously on the mounting seat 1 to approach each other to clamp the main body or to separate from each other to release the main body.

[0066] Specifically, taking the example that the two clamping blocks 31 are arranged on the left and right sides of the first follower 22 respectively, when the first follower 22 moves upward under the driving of the driving member 21, one end of the two clamping blocks 31 moves upward, so that the left clamping block 31 rotates counterclockwise and the right clamping block 31 rotates clockwise, thereby causing the two clamping blocks 31 to approach each other to clamp the guide rail. When the first follower 22 resets downward under the driving of the first reset member 25, one end of the two clamping blocks 31 moves downward, so that the left clamping block 31 rotates clockwise and the right clamping block 31 rotates counterclockwise, thereby causing the two clamping blocks 31 to separate from each other and release the guide rail.

[0067] In the embodiment, the lifting of the first follower 22 can simultaneously drive the two clamping blocks 31 to rotate to clamp or release, which is simple in structure and easy to drive. The fixed device can be used to fix the operating bed in the non-sterile area, and can also be clamped on the guide rail of the operating bed covered with a sterile operating bed sheet through the two clamping blocks 31, so that the fixed device can be used to fix the accessories in the non-sterile area and can also be used to fix the accessories that need to be treated in a sterile manner, which has a wide range of applications and is convenient for doctors to use.

[0068] In one embodiment, referring to Figure 4 , Figure 5 and Figure 8 , the clamping block 31 comprises a connecting plate 311, a clamping plate 312 and an abutting plate 313, which are sequentially and foldably connected, and the connecting plate 311 and the abutting plate 313 are arranged opposite to each other. One end of the connecting plate 311 away from the clamping plate 312 is connected with the first follower 22, and the connection between the connecting plate 311 and the clamping plate 312 is rotatably arranged on the mounting seat 1. The clamping plates 312 of the two clamping blocks 31 are used to clamp the opposite sides of the main body respectively, and the abutting plates 313 of the two clamping blocks 31 are used to abut against one side of the main body away from the first follower 22 respectively. In the embodiment, the clamping block 31 is sequentially and foldably connected by the connecting plate 311, the clamping plate 312 and the abutting plate 313, so that the clamping block 31 is approximately U-shaped. When the two clamping blocks 31 clamp the guide rail towards each other, the guide rail can be surrounded by the two clamping blocks 31. Specifically, the two clamping plates 312 are clamped and abut against the opposite left and right sides of the guide rail respectively, and the two abutting plates 313 are abutted and hooked on the lower side of the guide rail respectively, and the two connecting plates 311 enclose the upper side of the guide rail, so that the guide rail can be tightly clamped.

[0069] Please refer to Figure 3 , Figure 4 and Figure 6 , the bottom center of the mounting seat 1 is provided with a receiving groove 13, the lengths of the connecting plate 311 and the clamping plate 312 are less than the length of the abutting plate 313, the connecting plate 311 and at least part of the clamping plate 312 are accommodated in the receiving groove 13, and the abutting plate 313 extends to the lower side of the mounting seat 1. In this embodiment, because the length of the guide rail is relatively long, in order to ensure that the clamping mechanism 3 can clamp the guide rail, the length of the clamping block 31 needs to be set to be relatively long, and if the length of the clamping block 31 is too long, the clamping block 31 can only be arranged on the outside of the bottom of the mounting seat 1, and such arrangement will make the structure of the entire fixing device large and occupy a large space. In this embodiment, the lengths of the connecting plate 311 and the clamping plate 312 of the clamping block 31 are set to be relatively small compared with the length of the abutting plate 313, and the receiving groove 13 is arranged at the bottom of the mounting seat 1, so that the connecting plate 311 and at least part of the clamping plate 312 can be accommodated in the receiving groove 13, which can greatly reduce the overall space occupied by the mounting seat 1 and the clamping block 31, and ensure the clamping firmness of the clamping block 31 to the guide rail, and on the other hand, the combination between the mounting seat 1 and the clamping block 31 is more firm, and the structure of the entire fixing device is more compact and firm.

[0070] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 8 , the mounting seat 1 is provided with a first shaft hole 14, the connecting part of the connecting plate 311 and the clamping plate 312 is provided with a second shaft hole 314, and the clamping mechanism 3 further comprises a first rotating shaft 32, the opposite ends of the first rotating shaft 32 are respectively fixed in the first shaft hole 14, and the middle section of the first rotating shaft 32 penetrates through the second shaft hole 314. When the clamping block 31 is driven, the clamping block 31 rotates around the first rotating shaft 32.

[0071] Please refer to Figure 5 and Figure 7 , the clamping mechanism 3 further comprises a second rotating shaft 33, the bottom end outer wall of the first driven part 22 is provided with a slot 222, one end of the second rotating shaft 33 is fixed on the connecting plate 311, and the other end of the second rotating shaft 33 is inserted into the slot 222. When the first driven part 22 is lifted, the second rotating shaft 33 can be lifted to push the connecting plate 311 to rotate the clamping block 31 around the first rotating shaft 32. In addition, because the connecting plate 311 rotates when the clamping block 31 rotates, the second rotating shaft 33 slides in the slot 222.

[0072] Please refer to Figure 5The first follower 22 is substantially cylindrical, and in order to realize the connection between the connecting plate 311 and the first follower 22, the connecting plate 311 is provided with a gap 3111 avoiding the first follower 22, and the first follower 22 is at least partially inserted into the gap 3111, and the positions of the connecting plate 311 on both sides of the gap 3111 are connected with the corresponding positions of the first follower 22 through the second rotating shaft 33.

[0073] In addition, referring to Figure 5 The bottom end of the first follower 22 is provided with a limiting plate 223, which is used for limiting the position of the connecting plate 311. Specifically, the limiting plate 223 is horizontally arranged, the connecting plate 311 is above the limiting plate 223 and is rotationally connected with the first follower 22, when the connecting plate 311 rotates to the horizontal state, the limiting plate 223 is abutted with the connecting plate 311, thereby preventing the connecting plate 311 from continuing to rotate, and thereby realizing the rotation limiting of the clamping block 31, and at the same time, enabling the clamping block 31 to be stably kept in the state of clamping the guide rail.

[0074] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
