Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-5 This utility model provides a thoracic spine protective brace, including a neck support 100 and a chest support 200 arranged vertically. The chest support 200 includes a front chest support 210 and a back support 220 arranged front to back. A telescopic member 230 is provided between the front chest support 210 and the neck support 100, and between the back support 220 and the neck support 100. A connecting member is provided between the front chest support 210 and the back support 220. A locking member 250 for limiting the position is provided on the telescopic member 230. The telescopic member 230 includes a shell 231. The front chest support 210 is fixedly connected to the bottom of one of the shells 231, and the back support 220 is fixedly connected to the bottom of the other shell 231. An inner plate 232 is slidably provided through the inner cavity of the shell 231.
[0030] The snap-fit component 250 includes grooves 251 formed on both sides of the surface of the inner plate 232. The inner cavity of the groove 251 is rotatably connected to the claw 252 through a torsion spring shaft. The outer shell 231 has multiple slots 2311 that are equidistantly distributed vertically on the side. One end of the claw 252 extends through the inner cavity of the corresponding slot 2311.
[0031] It should be noted that the aforementioned torsion spring shaft can be a type of assisted torsion spring shaft disclosed in the existing publication number CN218863077U. When the claw 252 is subjected to force, it can rotate through the torsion spring shaft, and when it loses its constraint, it can be reset by the action of the torsion spring shaft and can be locked into the corresponding slot 2311 for further limiting. This is existing technology, so it will not be described in detail in this technical solution.
[0032] The telescopic component 230 also includes 233, which is fixedly connected to the upper part of the surface of the outer shell 231. One side of 233 is in contact with the surface of the inner plate 232. 233 can limit the inner plate 232, so that the inner plate 232 can slide stably up and down in the inner cavity of the outer shell 231.
[0033] The connector includes a third connecting strap 240, with one third connecting strap 240 fixedly connected to each side of the back support 220. The hook and loop fastener at the free end of the third connecting strap 240 passes through the connecting ring on the front chest support 210 and then folds back to adhere to the hook and loop fastener at its fixed end. By adjusting the adhesion position of the hook and loop fastener on the third connecting strap 240, the tightness of the two third connecting straps 240 can be adjusted to suit the patient's body shape and achieve effective support and protection.
[0034] The top of the pawl 252 contacts one side of the inner wall of the groove 251. The inner wall of the groove 251 can block the pawl 252 and prevent the pawl 252 from rotating excessively around the torsion spring shaft.
[0035] The inner plate 232 is also provided with a locking member 260 for positioning the bottom end of the claw 252. The locking member 260 includes a bolt 261 that movably passes through the lower part of the surface of the inner plate 232. A U-shaped plate 262 is sleeved on the surface of the bolt 261. The two sides of the U-shaped plate 262 pass through two grooves 251 respectively. The two sides of the outer surface of the U-shaped plate 262 are respectively fixedly connected to protrusions 263 that contact one side of the corresponding claw 252. By rotating the bolt 261, the U-shaped plate 262 and the protrusions 263 can be driven along the thread by the thread. The axial movement of bolt 261 causes protrusion 263 to gradually contact or disengage from claw 252. When protrusion 263 contacts claw 252, claw 252 can be positioned to prevent it from accidentally disengaging from the corresponding slot 2311 due to external force, thus ensuring the connection stability between outer shell 231 and inner plate 232. When protrusion 263 disengages from claw 252, claw 252 can be unlocked, allowing for quick adjustment of the length of inner plate 232 extending out of outer shell 231 according to actual usage requirements.
[0036] The surface of bolt 261 is rotatably connected to the inner plate 232 through the bearing to ensure the movable connection between the inner plate 232 and bolt 261.
[0037] The inner plate 232 has a through groove 264 for the side of the U-shaped plate 262 to pass through. One side of the inner cavity of the through groove 264 is connected to the inner cavity of the groove 251. The inner wall of the through groove 264 is slidably connected to the surface of the U-shaped plate 262. The through groove 264 can guide the U-shaped plate 262, so that the U-shaped plate 262 can move stably along the axial direction of the bolt 261, and prevent the U-shaped plate 262 from rotating synchronously with the bolt 261.
[0038] The neck support 100 includes a chin support 110 and a posterior neck support 120 arranged front to back. The surface of the chin support 110 is fixedly connected to the top of the corresponding inner plate 232, and the surface of the posterior neck support 120 is fixedly connected to the top of the corresponding inner plate 232. The surface of the chin support 110 is connected to two symmetrical first connecting straps 130 via connecting rings, and the surface of the posterior neck support 120 is connected to two symmetrical second connecting straps 140 via connecting rings. The second connecting straps 140 and the first connecting straps 130 are arranged in a one-to-one correspondence, and the second connecting straps 140 and the corresponding first connecting straps 130 are connected by Velcro. The neck support 100 can immobilize and protect the cervical spine, reduce nerve wear, alleviate traumatic reactions of the intervertebral joints, and help reduce tissue edema, consolidate therapeutic effects, and prevent recurrence.
[0039] The working principle of this utility model is as follows: By turning the bolt 261 in the forward direction, under the action of the thread, the bolt 261 drives the U-shaped plate 262 to move along the axial direction of the bolt 261, so that the side of the U-shaped plate 262 slides in the inner cavity of the through groove 264. The U-shaped plate 262 drives the protrusion 263 to move, so that the protrusion 263 disengages from the pawl 252, thereby unlocking the pawl 252. If it is necessary to shorten the overall length of the telescopic component 230, the bottom ends of the two pawls 252 are pinched together, so that the pawls 252 rotate around the torsion spring shaft. The bottom ends of the pawls 252 disengage from the inner cavity of the slot 2311, thereby unlocking the inner plate 23. 2. Unlock. At this point, the inner panel 232 can be moved downwards, gradually sliding into the inner cavity of the outer shell 231. The inner panel 232 moves the locking member 260 and the neck support 100 simultaneously, gradually shortening the distance between the front chest support 210 and the neck support 100, and between the back support 220 and the neck support 100, until the inner panel 232 reaches the desired position. Then, release the claw 252, and the torsion spring shaft will cause the claw 252 to reset and engage in the corresponding slot 2311, thus limiting the inner panel 232. If it is necessary to extend the overall length of the telescopic member 230, simply... Pulling plate 232 upward causes the inner plate 232 to move synchronously with the snap-fit component 250 and the locking component 260. The claw 252 is pressed by the inner wall of the outer shell 231, causing the claw 252 to automatically rotate around the torsion spring shaft. This gradually shortens the distance between the front chest support 210 and the neck support 100, and between the back support 220 and the neck support 100, until the inner plate 232 moves to the desired position. At this point, the claw 252 loses its constraint and, under the action of the torsion spring shaft, resets and locks into the corresponding slot 2311, thus limiting the inner plate 232. Then, the bolt 26 is turned in the opposite direction. 1. Once the protrusion 263 contacts the latch 252, the latch 252 can be positioned, thus completing the adjustment of the distance between the neck support 100 and the front chest support 210, and between the neck support 100 and the back support 220. Through the combined use of the first connecting strap 130 and the second connecting strap 140, the chin support 110 and the back neck support 120 are fixed to the front and back sides of the patient's neck, respectively. Through the third connecting strap 240, the front chest support 210 and the back support 220 are fixed to the front and back sides of the patient's ribcage, respectively. Thus, the neck support 100 and the chest support 200 can maintain the stability of the spine during the rehabilitation period and improve the spine's weight-bearing capacity.
[0040] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
