Description

Technical Field

[0001] This utility model belongs to the technical field of rehabilitation aids, specifically relating to an assembled cutting aid. Background Technology

[0002] Rehabilitation aids (full name: rehabilitation assistive devices, also often referred to as rehabilitation assistive device products or rehabilitation assistive technology products) refer to products designed to improve, compensate for, or replace human functions, assist in treatment, and prevent disability. These include appliances, equipment, instruments, technologies, and software, which provide auxiliary support (such as prostheses, hearing aids, and cognitive training software) for functional impairments such as limb, sensory, and cognitive impairments, thereby achieving functional compensation and replacement.

[0003] To help people with limb dysfunction independently process food, a cutting aid is needed. However, the operating part of the cutting aid and the food pressing part are assembled with bolts. The bolt connection requires the use of tools (such as wrenches and screwdrivers) to install and disassemble. For users who operate with one hand or lack strength, this may increase the difficulty of use. Repeatedly tightening or loosening the bolts will prolong the assembly or cleaning time of the equipment and reduce the efficiency of use. Utility Model Content

[0004] The purpose of this invention is to provide an assembly-type cutting aid to solve the technical problem of bolted connections requiring tools for installation and disassembly, thereby achieving rapid assembly.

[0005] To solve the above-mentioned technical problems, this utility model provides an assembled cutting aid, including: a lower pressure frame and a connecting frame. The connecting frame is fixedly connected to one side of the lower pressure frame. A food fixing device is provided below the connecting frame. A mounting shell is movably connected to the inner cavity of the connecting frame. A connecting hook is installed at the bottom of the mounting shell. Two movable plates are movably connected to the inner cavity of the mounting shell. A locking post is fixedly connected to one side of the movable plate. A locking groove for cooperating with the locking post is opened on the inner side of the connecting frame. A guide is provided in the inner cavity of the mounting shell. A pull rope is provided between the two movable plates. A central shaft block is fixedly connected to the inner cavity of the mounting shell. The inner cavity of the central shaft block movably passes through the pull rope.

[0006] Furthermore, the two locking posts are respectively fixedly connected to the opposite sides of the two movable plates, and one end of the locking post extends movably through to the outside of the mounting shell and is movably connected to the inner cavity of the locking groove.

[0007] Furthermore, the guide includes two guide posts that are laterally fixedly connected to the inner cavity of the mounting shell, the surfaces of the two movable plates are slidably connected to the two guide posts respectively, and springs are sleeved on the surfaces of the guide posts, with the two ends of the springs being fixedly connected to the two movable plates respectively.

[0008] Furthermore, the pull rope is Y-shaped, with its top two ends fixedly connected to the middle of the two movable plates, and its bottom end extending through to the bottom of the mounting shell and fixedly connected to a connecting hook.

[0009] Furthermore, a connecting ring is fixedly connected to the top of the food fixing device, and the connecting hook and the connecting ring can be used together.

[0010] Furthermore, a connecting plate is fixedly connected to the top of the food fixing device, and the connecting plate is fixedly connected to the bottom of the mounting shell.

[0011] Furthermore, the inner cavity of the central shaft block is provided with a movable groove, the shape of which is adapted to the shape of the pull rope connection.

[0012] Furthermore, a support plate is rotatably connected to the top of the mounting shell, and the width of the support plate is greater than the width of the mounting shell.

[0013] The beneficial effects of this utility model are:

[0014] 1. Users can pull down the bottom of the pull rope to make the two moving plates move towards each other, and the locking post will disengage from the inner cavity of the locking slot, thus unlocking the mounting shell and connecting frame. This makes it easy to disassemble the mounting shell from the food fixing device, allowing users to complete the assembly with one hand. It is especially suitable for people with unilateral limb dysfunction, providing independent operation for hemiplegic, amputee, or weak individuals, enhancing their self-care ability. It is also quick to assemble and easy to store, saving kitchen space.

[0015] 2. Rotate the support plate to support the mounting shell. When unlocking, pull the connecting hook to hook with the connecting ring to keep it unlocked. Then rotate the support plate to finally unlock the mounting shell. The support plate prevents the food fixing utensil from falling due to accidental pulling of the connecting hook, forming a double lock to improve overall stability. Both locks can be operated with one hand.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example:

[0027] like Figures 1 to 5 As shown, an assembled cutting aid includes: a lower pressure frame 1 and a connecting frame 2. The connecting frame 2 is fixedly connected to one side of the lower pressure frame 1. A food fixing device 3 is provided below the connecting frame 2. A mounting shell 4 is movably connected to the inner cavity of the connecting frame 2. A connecting hook 10 is installed at the bottom of the mounting shell 4. Two movable plates 5 are movably connected to the inner cavity of the mounting shell 4. A locking post 6 is fixedly connected to one side of the movable plate 5. A locking groove 7 is opened on the inner side of the connecting frame 2 to cooperate with the locking post 6. The locking structure of the locking post 6 and the locking groove 7 can realize the quick locking and unlocking of the mounting shell 4 and the connecting frame 2, simplifying the operation process. A guide 8 is provided in the inner cavity of the mounting shell 4. A pull rope 9 is provided between the two movable plates 5. A central shaft block 13 is fixedly connected to the inner cavity of the mounting shell 4. The inner cavity of the central shaft block 13 and the pull rope 9 movably pass through it.

[0028] like Figures 1 to 5As shown, two locking posts 6 are fixedly connected to the opposite sides of two movable plates 5. One end of the locking post 6 extends movably through the outer side of the mounting shell 4 and is movably connected to the inner cavity of the locking groove 7. The guide member 8 includes two guide posts 81 that are laterally fixedly connected to the inner cavity of the mounting shell 4. The surfaces of the two movable plates 5 are slidably connected to the two guide posts 81. The guide posts 81 ensure that the movable plates 5 move in a straight line, avoiding deviation that could lead to locking failure. A spring 82 is sleeved on the surface of the guide posts 81. The two ends of the spring 82 are fixedly connected to the two movable plates 5. The spring 82 provides a preload force, so that the movable plates 5 automatically reset when there is no external force, maintaining a stable connection between the locking post 6 and the locking groove 7. The pull rope 9 is Y-shaped. The two ends of the top of the pull rope 9 are fixedly connected to the middle of the two movable plates 5. The bottom end of the pull rope 9 extends movably through the bottom of the mounting shell 4 and is fixedly connected to a connecting hook 10. The connecting hook 10 allows the user to pull the pull rope 9. Unlocking is achieved through intuitive and simple operation. The Y-shaped pull rope 9 evenly transmits the user's pulling force on the connecting hook 10 to the two moving plates 5, ensuring that the locking post 6 retracts synchronously. A connecting ring 11 is fixedly connected to the top of the food fixing device 3, and the connecting hook 10 and the connecting ring 11 can be used together. A connecting plate 12 is fixedly connected to the top of the food fixing device 3, and the connecting plate 12 is fixedly connected to the bottom of the mounting shell 4. The inner cavity of the central shaft block 13 has a movable groove 14, the shape of which is adapted to the shape of the connection of the pull rope 9. The movable groove 14 of the central shaft block 13 provides guidance for the pull rope 9, reduces friction, and improves the smoothness of operation. A support plate 15 is rotatably connected to the top of the mounting shell 4. The width of the support plate 15 is greater than the width of the mounting shell 4. After the support plate 15 rotates, it supports the mounting shell 4 to prevent it from falling off accidentally. The user needs to rotate the support plate 15 to finally remove the mounting shell 4 to avoid accidental operation that could cause the parts to fall off.

[0029] In summary, during assembly and disassembly, by pulling down the connecting hook 10, the bottom end of the pull rope 9 moves downward synchronously, causing the two ends of the top of the pull rope 9 to move the two moving plates 5 towards each other. The spring 82 is compressed, and the moving plate 5 causes the locking post 6 to disengage from the inner cavity of the locking groove 7, thus unlocking the mounting shell 4. The connecting hook 10 is then hooked to the connecting ring 11, and the locking post 6 remains unlocked. Finally, the support plate 15 is rotated so that it does not contact the connecting frame 2, allowing the mounting shell 4 and the food fixing device 3 to be disassembled downward from the connecting frame 2.
