DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] like Figures 1 to 3As shown, the ankle joint fixation device of this embodiment includes a front cover body 1, a rear cover body 2, a slide rail 5 and a locking assembly 4, wherein the side of the front cover body 1 is L-shaped, including a portion for fitting and covering the instep and a portion for covering the front side of the heel, and the inner side of the front cover body 1 is provided with a groove, and the shape of the groove is the same as the shape of the patient's foot, so that it can stably cover the instep and the front side of the heel. The rear cover body 2 is semi-cylindrical, used to cover the rear side of the heel, and the rear cover body 2 is spliced ​​with the front cover body 1 covering the front side of the heel, and the lower end of the rear cover body 2 is fixedly connected with a bottom plate 3, and the bottom plate 3 is used to support the sole of the foot. The shape of the general bottom plate is roughly the same as the shape of the sole of the foot.

[0020] The slide rails 5 include two rails which are arranged in parallel on both sides of the base plate 3. The slide rails 5 are located on the upper end surface of the base plate 3. The lower end surface of the front cover body 1 is provided with a slide groove 6, which is slidably connected to the slide groove 6. The cross-sections of the slide rails 5 and the slide groove 6 are both I-shaped.

[0021] The locking assembly 4 is disposed between the front cover body 1 and the rear cover body 2, and is used to fix the front cover body 1 and the rear cover body 2. Regarding the number of locking assemblies 4, this embodiment adopts a solution in which a group of locking assemblies 4 are respectively disposed on the left and right sides of the front cover body 1 and the rear cover body 2, so that the left and right sides of the front cover body 1 and the rear cover body 2 are locked and connected by the locking assemblies 4. In some other solutions, in order to strengthen stability, 1 to 2 groups of locking assemblies 4 can also be added to each side of the front cover body 1 and the rear cover body 2, so that they are more stable. The locking assembly 4 includes two identical structures, one fixed on the front cover body 1, and the other fixed on the rear cover body 2. The two locking assemblies 4 are symmetrical up and down and left and right, that is, the two locking assemblies 4 are both L-shaped in appearance, and can be combined to form a rectangular parallelepiped shape.

[0022] Specifically, the lock assembly 4 includes a shell 41, a buckle body 47, a rotating rod 46 and a spring 45. A locking chamber 44, a rotating rod chamber 43 and a spring chamber 42 are provided in the shell 41. The rotating rod chamber 43 and the rotating rod chamber 43 are V-shaped. The locking chamber 44 is connected to one end of the rotating rod chamber 43. The shell 41 can be fixed on the outer surface of the front cover body 1 or the rear cover body 2 by rivets. Generally, in order to facilitate the installation of the buckle body 47, the rotating rod 46 and the spring 45, the shell 41 has a matching upper shell and a lower shell. After the buckle body 47, the rotating rod 46 and the spring 45 are installed in the lower shell, the upper shell is fixedly connected to the lower shell, so that the buckle body 47, the rotating rod 46 and the spring 45 can be confined inside the shell 41.

[0023] The buckle body 47 is semicircular and is disposed in the locking cavity 44. The rotating rod 46 is disposed in the rotating rod cavity 43, one end of which is fixedly connected to the buckle body 47 and the other end of which extends out of the housing 41. The spring 45 is disposed in the spring cavity 42, one end of which is fixed to the housing 41 and the other end of which is connected to the middle of the rotating rod 46. Initially, the spring 45 is in the original length state, and part of the buckle body 47 protrudes out of the outer side of the locking cavity 44. In addition, the lock assembly 4 also includes a positioning pin 48 and a pin hole 49. The positioning pins 48 and the pin holes 49 on the two lock assemblies 4 are matched and connected with each other. Generally, the positioning pin 48 is disposed at the end of the housing 41, and the pin hole 49 is located on the stepped surface matched with the end. The positioning pin 48 has a guiding and positioning function, and after the positioning pin 48 is connected to the pin hole 49, the two lock assemblies 4 are also locked with each other in the up and down directions.

[0024] During use, after the patient places his feet on the base plate 3, the slide groove 6 at the bottom of the front cover body 1 and the slide rail 5 on the base plate 3 are aligned, and the front cover body 1 slides toward the rear cover body 2, and is finally connected through the lock assembly 4. When the lock assembly 4 of the front cover body 1 docks with the lock assembly 4 on the rear cover body 2, the shell 41 completely presses the buckle body 47 into the locking cavity 44. During this process, the spring 45 is in a stretched state. When the locking cavities 44 of the two lock assemblies 4 are opposite to each other, the two locking cavities 44 form a complete circular shape. At this time, the spring 45 returns to its original state and drives the buckle body 47 to rotate through the rotating rod 46, so that a part of the buckle body 47 on the two lock assemblies 4 is inserted into the locking cavity 44 on the opposite side, thereby fixing the front cover body 1 and the rear cover body 2 together. When disassembly is required, one only needs to rotate the rotating rod 46 to separate the buckle body 47 from the locking cavity 44 on the opposite side, and then slide the front cover body 1 away from the rear cover body 2 to separate the front cover body 1 and the rear cover body 2. Therefore, the ankle joint fixation device is more convenient and easy to use in operation.

[0025] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
