Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a rapid fixation and release mechanism. Background Technology

[0002] In the field of medical care, support and immobilization of the arms or legs are common needs when patients are resting, receiving treatment, or undergoing rehabilitation training in bed. For example, in scenarios such as arm or leg injuries, postoperative recovery, intravenous therapy, or rehabilitation training, patients need proper support for their arms or legs to reduce pain, promote blood circulation, maintain a comfortable posture, or avoid unnecessary movement.

[0003] However, existing support pads require tightening bolts to lock the angle during fixation. In clinical nursing work, nurses vary in strength and physical ability. Some nurses are less strong and may not be able to tighten the bolts sufficiently, causing the support pad to become loose or slip during patient use. This not only affects the patient's experience but may also negatively impact their recovery and reduce nursing efficiency.

[0004] This application studies a quick-release mechanism that allows for easy loosening or securing of the support pad, improving patient experience and nursing efficiency. Utility Model Content

[0005] In order to facilitate the loosening or fixing of the support pad and improve patient experience and nursing efficiency, this application provides a quick-fixing and releasing mechanism.

[0006] This application provides a quick-release mechanism, which adopts the following technical solution:

[0007] A quick-release mechanism includes a mounting base, a rotating component, an eccentric component, and an elastic component. The eccentric component is limited to rotating within the mounting base, the elastic component abuts against one side of the eccentric component, and one end of the rotating component is limited to rotating within the mounting base and abuts against the side of the elastic component opposite to the eccentric component. When the eccentric component does not compress the elastic component, the elastic component is in a natural state, and the rotating component can rotate within the mounting base. When the eccentric component rotates and compresses the elastic component, the elastic component presses against one side of the rotating component, and the rotating component is fixed.

[0008] By adopting the above technical solution, the rotating component is used to install the support pad. Through the cooperation of the eccentric component and the elastic component, the rotating component can be quickly fixed and released. When the eccentric component does not compress the elastic component, the elastic component is in its natural state, and the rotating component can rotate freely within the mounting base. This allows for quick adjustment of the angle of the support pad according to the patient's needs, meeting the personalized support requirements of different patients. When the eccentric component rotates and compresses the elastic component, the elastic component presses against one side of the rotating component, generating sufficient pressure to fix the rotating component in its current position, thereby ensuring the stability of the support pad during use. Therefore, the operation is simple, and nursing staff can easily rotate the eccentric component to fix or release the support pad, greatly reducing the difficulty of operation and improving nursing efficiency.

[0009] Optionally, the eccentric component includes an eccentric block and a rotating rod. The eccentric block is sleeved and fixed to the rotating rod. Both ends of the rotating rod pass through the two sides of the mounting base, with one side limiting rotation on the mounting base and the other side used for hand-held rotation.

[0010] Optionally, a limiting groove is provided in the middle section of the rotating rod and extends to one end. An external thread is provided near the end. At least two limiting blocks are sleeved in the limiting groove. The limiting blocks abut against the inner and outer sides of the mounting base respectively. A bolt is screwed onto the rotating rod and abuts against the outer limiting block.

[0011] Optionally, the eccentric block is fitted into the limiting groove, with one side abutting against the groove wall of the limiting groove and the other side abutting against the limiting block inside the mounting base.

[0012] By adopting the above technical solution, it is possible to conveniently limit and fix the left and right movement of the eccentric block.

[0013] Optionally, a rotating handle is connected to one side of the rotating rod, and the rotating handle is arranged perpendicular to the rotating rod.

[0014] Optionally, the rotating component includes a rotating ball and a connecting rod connected to each other, the rotating ball being rotatably connected within the mounting base, and the connecting rod extending out of one end of the mounting base.

[0015] Optionally, the inner wall of the mounting base is adapted to the shape of the rotating ball.

[0016] By adopting the above technical solution, the rotating ball can perform more stable limited rotation.

[0017] Optionally, it may also include at least two pressing members, which are respectively connected to both ends of the elastic member.

[0018] By adopting the above technical solution, the rotation of the eccentric component presses against the pressing component, thereby compressing the elastic component. This increases the contact area and makes the compression of the elastic component more stable. The elastic component increases the contact area between itself and the rotating ball through the pressing component, making it more stable in pressing against the rotating ball.

[0019] Optionally, the outer periphery of the pressing member slides along the inner periphery of the mounting base.

[0020] Optionally, the pressing member facing the side of the rotating ball is adapted to the shape of the rotating ball.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Through the cooperation of the eccentric component and the elastic component, the rotating component can be quickly fixed and released. When the eccentric component is not compressed by the elastic component, the elastic component is in its natural state, and the rotating component can rotate freely within the mounting base. This allows for quick adjustment of the support pad angle according to the patient's needs, meeting the personalized support requirements of different patients. When the eccentric component rotates and compresses the elastic component, the elastic component presses against the rotating component to one side, generating sufficient pressure to fix the rotating component in its current position, thus ensuring the stability of the support pad during use. Therefore, the operation is simple, and nursing staff can easily rotate the eccentric component to fix or release the support pad, greatly reducing the difficulty of operation and improving nursing efficiency.

[0023] 2. The limiting groove and the limiting block work together to limit the rotation of the rotating rod. The interaction between the limiting block, the fixed seat and the eccentric block makes it easy to limit and fix the left and right movement of the eccentric block.

[0024] 3. The rotation of the eccentric component presses against the pressing component, thereby compressing the elastic component, increasing the contact area, and making the compression of the elastic component more stable. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a quick-release mechanism. (Refer to...) Figure 1 and Figure 2 The quick-release mechanism includes a mounting base 1, a rotating component 2, an eccentric component 3, and an elastic component 4. The eccentric component 3 is limited to rotating within the mounting base 1, and the elastic component 4 abuts against one side of the eccentric component 3. When the eccentric component 3 rotates, it can abut against or release the elastic component 4. When the eccentric component 3 abuts against the elastic component 4, the elastic component 4 is fully compressed. In this embodiment, the elastic component 4 is a spring. One end of the rotating component 2 is limited to rotating within the mounting base 1. The rotating component 2 is used to install a support pad and abuts against the side of the elastic component 4 away from the eccentric component 3. The compression or release of the elastic component 4 fixes or releases the rotating component 2.

[0031] When the eccentric component 3 is not compressed, the elastic component 4 is in its natural state, and the rotating component 2 can rotate within the mounting base 1, allowing the support pad to be rotated to any position. When the eccentric component 3 rotates and compresses the elastic component 4, the elastic component 4 presses against the rotating component 2, fixing the rotating component 2. At this point, it can be fixed at any position according to the patient's needs. Furthermore, because the elastic component 4 is completely compressed, the rotating component 2 will not rotate when the patient is supported on the support pad, ensuring its stable fixation. This allows for convenient fixing or releasing of the support pad; medical staff only need to rotate the eccentric component 3 to different angles, thus greatly reducing operational difficulty and improving nursing efficiency.

[0032] Reference Figure 2 and Figure 3 In some embodiments, the eccentric component 3 includes an eccentric block 31 and a rotating rod 32. The opposite sides of the eccentric block 31 have the same thickness, with one set of opposite sides having a greater thickness than the other set. Both outer surfaces are planar, and two opposite angles are arc-shaped. Therefore, the arc-shaped angles facilitate rotation and pressure on the elastic component 4. The eccentric block 31 is fitted and fixed to the rotating rod 32. Both ends of the rotating rod 32 pass through the two sides of the mounting base 1, with one side limiting rotation on the mounting base 1 and the other side used for hand-held rotation.

[0033] In some embodiments, a limiting groove 5 is provided in the middle section of the rotating rod 32 and extends to one end. An external thread is provided near the end. At least two limiting blocks 6 are sleeved in the limiting groove 5. The limiting blocks 6 abut against the inner and outer sides of the mounting base 1 respectively. The bolt 9 is screwed to the rotating rod 32 and abuts against the outer limiting block 6, so that the rotating rod 32 can be limited on the mounting base 1, and the rotating rod 32 can still rotate.

[0034] In some embodiments, the eccentric block 31 is fitted into the limiting groove 5, and the four sides of the limiting groove 5 of the rotating rod 32 are chamfered. The inner side of the eccentric block 31 cooperates with the chamfer of the rotating rod 32, so that the eccentric block 31 is limited and fixed to the rotating rod 32 in the circumferential direction, so that the rotating rod 32 can stably drive the eccentric block 31 to rotate when it rotates. One side of the eccentric block 31 abuts against the groove wall of the limiting groove 5, and the other side abuts against the limiting block 6 inside the mounting base 1, so that the eccentric block 31 is limited along the length direction of the rotating rod 32.

[0035] Refer again Figure 1 In some embodiments, a rotating handle 7 is connected to one side of the rotating rod 32, and the rotating handle 7 is set perpendicular to the rotating rod 32. By rotating the rotating handle 7 around the central axis of the rotating rod 32, the rotating rod 32 is rotated, which rotates the eccentric member 3 to different positions to compress or release the elastic member 4, so that medical staff can rotate the eccentric member 3 more easily and effortlessly.

[0036] Reference Figure 2 In some embodiments, the rotating component 2 includes a rotating ball 21 and a connecting rod 22 connected to each other. In this embodiment, the connecting rod 22 is integrally connected to one side of the rotating ball 21, and the rotating ball 21 is rotatably connected to the mounting base 1. The connecting rod 22 extends out of one end of the mounting base 1 and is used to install the support pad, making it easy to install the support pad. At the same time, the rotating ball 21 can drive the support pad to rotate at any angle. In some embodiments, the inner sidewall of the mounting base 1 is adapted to the shape of the rotating ball 21. So that when the support pad needs to be fixed, the rotating ball 21 can be more stably abutted, so that the support pad can be more stable.

[0037] In some embodiments, the quick-release mechanism further includes at least two pressing members 8. In this embodiment, the pressing members 8 are cylindrical block structures, and are respectively connected to both ends of the elastic member 4. This increases the contact area between the elastic member 4 and the eccentric member 3 and the rotating ball 21, so that when the eccentric block 31 rotates, it can rotate more stably along the pressing members 8 while pressing the pressing members 8, thereby stably compressing the elastic member 4 and stably pressing the rotating ball 21.

[0038] In some embodiments, the outer periphery of the pressing member 8 slides along the inner periphery of the mounting base 1, which also makes the elastic member 4 more stable.

[0039] Specifically, the pressing member 8 includes a first pressing member 81 and a second pressing member 82. The first pressing member 81 is located at the end of the elastic member 4 facing the rotating ball 21, and the second pressing member 82 is connected to the end of the elastic member 4 facing the eccentric member 3.

[0040] In some embodiments, the pressing member 8 facing the rotating ball 21 is adapted to the shape of the rotating ball 21. In this embodiment, the shape of the first pressing member 81 is adapted to the rotating ball 21, that is, the first pressing member 81 has a pressing groove 10, and the rotating ball 21 can be partially or completely placed in the pressing groove 10. In this embodiment, the rotating ball 21 is partially placed in the pressing groove 10, which can further stabilize the rotating ball 21.

[0041] The implementation principle of the quick-fixing and releasing mechanism in this application embodiment is as follows: through the cooperation of the eccentric member 3 and the elastic member 4, the quick fixing and releasing of the rotating member 2 is realized. When the eccentric member 3 does not compress the elastic member 4, the elastic member 4 is in a natural state, and the rotating member 2 can rotate freely within the mounting base 1, which facilitates the quick adjustment of the angle of the support pad according to the patient's needs, meeting the personalized support needs of different patients. When the eccentric member 3 rotates and compresses the elastic member 4, the elastic member 4 presses against the rotating member 2 to generate sufficient pressure to fix the rotating member 2 in the current position, thereby ensuring that the support pad remains stable during use. Therefore, the operation is simple, and nursing staff can easily rotate the eccentric member 3 to fix or release the support pad, greatly reducing the difficulty of operation and improving nursing efficiency.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
