[0036] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0037] This utility model provides an overall structural diagram of an embodiment of an adjustable-length orthopedic splint, including:

[0038] Please see Figures 1-5 An orthopedic splint with adjustable length for use in this embodiment includes a splint assembly 100, an extension plate assembly 200 disposed inside the splint assembly 100, and a fixation assembly 300 disposed on the side of the splint assembly 100.

[0039] The clamp assembly 100 includes a clamp first 110, a side cover 120 is provided on the top of the clamp first 110, a clamp second 160 is provided on the side of the clamp first 110, and the clamp second 160 is fixedly connected to the extension plate 210.

[0040] The extension plate assembly 200 includes an extension plate 210 disposed inside the clamping plate 110. A sliding plate 220 is fixedly connected to the top of the extension plate 210. A limiting block 250 is fixedly connected to the top of the extension plate 210. A bolt 260 is threadedly connected to the top of the limiting block 250.

[0041] The fixing assembly 300 includes a fixing plate 310 disposed on the side of the clamping plate 110, a spring 340 disposed on the side of the fixing plate 310, a pressing plate 320 disposed on the side of the spring 340, a rotating seat 350 fixedly connected to one side of the pressing plate 320, and a rotating column 360 rotatably connected inside the rotating seat 350.

[0042] It is worth noting that, in order to facilitate the installation of the side cover 120 on the clamp plate 110, specifically, a snap-fit ​​block 130 is fixedly connected to one side of the side cover 120, and a fixing block 140 is fixedly connected to the other side of the side cover 120. A square groove is provided on the top of the clamp plate 110.

[0043] Next, in order to facilitate the connection between the clamping plate 110 and the extension plate 210 and the sliding plate 220, the side of the clamping plate 110 is provided with a groove that matches the extension plate 210 and the sliding plate 220. The side of the groove is fixedly connected with a guide block 150, and the inner walls on both sides of the groove are provided with limiting grooves that match the limiting block 250.

[0044] Meanwhile, in order to reduce the resistance when the clamping plate extends and retracts, specifically, the bottom of the sliding plate 220 is provided with multiple sliding wheels 240, and the two sides of the sliding wheels 240 are rotatably connected to rotating shafts.

[0045] Furthermore, in order to better secure the extension plate 210, specifically, multiple snap-fit ​​teeth 230 are fixedly connected to the side of the extension plate 210, and the snap-fit ​​teeth 230 are arranged in an array on both sides of the extension plate 210.

[0046] When quick installation of the clamping plate is required, the fixing plate 310 on the side of the clamping plate 2 160 can be inserted into the clamping plate 1 110 first. Then, the limiting block 250 is fixed to the extension plate 210 by bolts 260 through the square groove, so that the limiting block 250 restricts the movement of the extension plate 210 and prevents it from separating from the clamping plate 2 160. The sliding wheel 240 at the bottom of the sliding plate 220 achieves the effect of fast sliding speed and quiet operation by sliding with the guide block 150.

[0047] It is worth noting that, in order to better secure the extension plate 210, the side of the pressing plate 320 is fixedly connected with a protruding clip that engages with the snap-fit ​​teeth 230, and the sides of both the pressing plate 320 and the fixing plate 310 are fixedly connected with fixing posts 370.

[0048] Finally, in order to prevent the pressing plate 320 from moving freely when no one is operating it, specifically, the other side of the pressing plate 320 is rotatably connected to a limit card 330, and the side of the limit card 330 is rotatably connected to a rotating shaft.

[0049] When fixation is required, pressing the pressing plate 320 causes the protruding clip on its side to disengage from the locking tooth 230, allowing the extension plate 210 to move freely within the clamping plate 110. The fixing posts 370 on the sides of the pressing plate 320 and the fixing plate 310 are designed to restrict the spring 340 from moving erratically. When fixation is required, releasing the pressing plate 320 causes the spring 340 to store the force applied during pressing, prompting the protruding clip on the side of the pressing plate 320 to engage with the locking tooth 230, thus achieving the fixation purpose. The limiting clip 330 on the side of the pressing plate 320 can rotate to completely lock the pressing plate 320, preventing it from moving due to external force.

[0050] Combination Figures 1-5 The following is a detailed usage process of an adjustable-length orthopedic splint for orthopedic use according to this embodiment:

[0051] 1. When the length of an orthopedic splint needs to be adjusted to fit the fracture site of different patients, the extension plate assembly 200 plays a crucial role. The sliding plate 220 slides smoothly within a pre-set groove inside the splint assembly 100 using multiple sliding wheels 240 located at its bottom. These sliding wheels 240 are mounted via a rotating shaft, reducing friction and ensuring the smooth movement of the extension plate 210. As the sliding plate 220 moves, the extension plate 210 extends or retracts within the groove, thus achieving flexible adjustment of the entire splint length. During this process, the limiting blocks 250 slide along the limiting grooves on both sides of the groove, ensuring the stability and accuracy of the extension plate 210 during adjustment.

[0052] 2. To further enhance the stability of the extension plate 210 after adjustment, the design of the fixing component 300 is particularly important. The pressing plate 320, through the elastic force provided by the spring 340, can tightly fit against the locking teeth 230 provided on the side of the extension plate 210. These locking teeth 230 are arranged in an array, providing multiple possible locking points for the pressing plate 320, thereby ensuring that the extension plate 210 is firmly fixed at different lengths. This facilitates quick and accurate engagement and disengagement of the locking teeth 230, improving operational convenience. The orthopedic splint can be freely extended and retracted by pressing the pressing plate 320.

[0053] 3. During the use of the orthopedic splint, the limiting clip 330 on the other side of the pressure plate 320 provides additional safety locking. The limiting clip 330 is mounted on the pressure plate 320 via a pivot. Once the pressure plate 320 successfully engages with the locking teeth 230, the limiting clip 330 can rotate to the appropriate position, preventing the pressure plate 320 from accidentally loosening due to external force, further ensuring the stability of the splint and the safety of the patient. Simultaneously, the fixing posts 370 on the side of the pressure plate 320 and the fixing plate 310 effectively restrict the uncontrolled movement of the spring 340.

[0054] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
