[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-4A protective cover for the moving parts of an implantation needle machine includes a base 1, the moving parts are disposed on the upper end face of the base 1, and an n-shaped mounting bracket 2 is fixedly connected to the upper end face of the base 1. The needle of the moving parts is located on the right side of the mounting bracket 2, and the connecting rod and cam of the moving parts are located on the left side of the mounting bracket 2. A first protective structure is provided on the upper end face of the base 1 on the left side of the mounting bracket 2, and a second protective structure is provided on the upper end face of the base 1 on the right side of the mounting bracket 2.

[0026] The first protective structure includes a first protective cover 3 disposed on the upper surface of the base 1 with an open structure at the right and lower ends. The upper surface of the base 1 has two first trapezoidal grooves 4 distributed front to back and open at the left end. The lower surface of the first protective cover 3 is fixedly connected to two first trapezoidal sliders 5 that match the two first trapezoidal grooves 4 respectively. The right side wall of the first protective cover 3 is fixedly connected to a plurality of evenly distributed fixing blocks 6. The upper surface of the plurality of fixing blocks 6 is provided with fixing holes 7. The interior of the mounting frame 2 has two cavities 8 distributed front to back. The left side wall of the mounting frame 2 is provided with a plurality of through holes 9 that communicate with the two cavities 8 respectively. The interior of the two cavities 8 is slidably connected to two moving blocks 10 distributed vertically. The lower surface of the plurality of moving blocks 10 is fixedly connected to fixing pins 11 that match the fixing holes 7.

[0027] The second protective structure includes a second protective cover 12 disposed on the upper surface of the base 1 with an open structure at the left and lower ends. Two second trapezoidal sliders 13 distributed front and back are fixedly connected to the lower end of the left side wall of the second protective cover 12. Two second trapezoidal grooves 14 are provided on the right side wall of the mounting bracket 2, which are respectively matched with the two second trapezoidal sliders 13. A limit mechanism is provided between the second trapezoidal grooves 14 and the second trapezoidal sliders 13.

[0028] In this embodiment: During use, the second protective cover 12 is pulled upward by the handle, so that the second protective cover 12 moves upward through the second trapezoidal slider 13 and the second trapezoidal slide groove 14, exposing the needle of the moving part and the worktable. The second protective cover 12 is then limited and fixed by the limiting mechanism. Then the brush base is fixed to the worktable. Then the second protective cover 12 is moved downward, so that the second protective cover 12 covers the needle of the moving part and the worktable, thereby protecting the needle of the moving part and the worktable, avoiding safety hazards, and preventing external debris and impurities from falling onto the worktable and affecting the normal operation of the needle of the needle implantation machine.

[0029] When disassembling the first protective cover 3, multiple moving blocks 10 move upwards, causing multiple fixing pins 11 to move out of multiple fixing holes 7, thereby releasing the fixing state of multiple fixing pins 11 on multiple fixing blocks 6. Then, the first protective cover 3 is pushed to the left, causing multiple fixing blocks 6 to move out of multiple through holes 9. At the same time, the first protective cover 3 moves on the base 1 through the first trapezoidal slide 4 and the first trapezoidal slider 5, thereby disassembling the first protective cover 3. When installing the first protective cover 3, the above steps are reversed, which facilitates the quick disassembly and installation of the first protective cover 3 and avoids affecting the efficiency of equipment debugging and maintenance.

[0030] As a technical optimization of this utility model, the limiting mechanism includes grooves 15 opened on the upper end of the front and rear inner sidewalls of the second trapezoidal slide groove 14. Limiting balls 16 are slidably connected inside the two grooves 15. A spring 17 is fixedly connected between the grooves 15 and the limiting balls 16. Limiting grooves 18 matching the limiting balls 16 are opened on the front and rear end faces of the second trapezoidal slider 13.

[0031] In this embodiment: when the second protective cover 12 moves to the top, the second trapezoidal slider 13 moves to the two limiting balls 16. During the movement, the second trapezoidal slider 13 squeezes the two limiting balls 16 into the two grooves 15 respectively, until the two limiting grooves 18 move to be flush with the two limiting balls 16. Then, the two springs 17 push the two limiting balls 16 to reset, so that the two limiting balls 16 enter the two limiting grooves 18. Then, the two limiting balls 16 and the two limiting grooves 18 cooperate with each other to limit and fix the second trapezoidal slider 13, thereby limiting and fixing the second protective cover 12.

[0032] As a technical optimization of this utility model, screws 19 are rotatably connected inside the two cavities 8, and multiple moving blocks 10 are arranged in groups of two, one above the other, with each group of moving blocks 10 threadedly connected to two screws 19.

[0033] In this embodiment: the two screws 19 rotate, and the two screws 19 respectively drive the two sets of moving blocks 10 to move up and down.

[0034] As a technical optimization of this utility model, the multiple moving blocks 10 and the two cavities 8 are slidably connected by limiting sliders and limiting grooves.

[0035] In this embodiment, the moving block 10 can be moved smoothly by the limiting slider and the limiting groove.

[0036] As a technical optimization of this utility model, a handle is fixedly connected to the upper end face of the second protective cover 12.

[0037] In this embodiment, the handle facilitates the movement of the second protective cover 12.

[0038] As a technical optimization of this utility model, the upper ends of the two screws 19 extend to the top of the mounting bracket 2 and are fixedly connected with torsion blocks.

[0039] In this embodiment, the torsion block facilitates the rotation of the screw 19.

[0040] As a technical optimization of this utility model, the left side wall of the first protective cover 3 is provided with multiple heat dissipation holes distributed vertically.

[0041] In this embodiment, heat dissipation can be achieved inside the first protective cover 3 through the heat dissipation holes.

[0042] The working principle and usage process of this utility model are as follows: When in use, the second protective cover 12 is pulled upward by the handle, so that the second protective cover 12 moves upward through the second trapezoidal slider 13 and the second trapezoidal slide groove 14, so that the needle of the moving part and the worktable are exposed. The second protective cover 12 is limited and fixed by the limiting mechanism. Then the brush base is fixed to the worktable. Then the second protective cover 12 is moved downward so that the second protective cover 12 covers the needle of the moving part and the worktable, thereby protecting the needle of the moving part and the worktable.

[0043] When disassembling the first protective cover 3, two screws 19 are rotated by two torsion blocks. The two screws 19 drive two sets of moving blocks 10 to move upward. Multiple moving blocks 10 drive multiple fixing pins 11 to move out of multiple fixing holes 7, thereby releasing the fixing state of multiple fixing pins 11 on multiple fixing blocks 6. Then, the first protective cover 3 is pushed to the left, so that multiple fixing blocks 6 move out of multiple through holes 9. At the same time, the first protective cover 3 moves on the base 1 through the first trapezoidal slide 4 and the first trapezoidal slider 5, thereby disassembling the first protective cover 3. When installing the first protective cover 3, the above steps are reversed, thus facilitating the quick disassembly and installation of the first protective cover 3.

[0045] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
