For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0030] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0031] Reference Figure 1 and Figure 2This application provides an instrument holder fixing device with an anti-loosening structure, including a base 1 and an instrument holder 2. An anti-loosening fixing mechanism 3 is provided on the top of the base 1 to fix the instrument holder 2 and prevent loosening. An ejection mechanism 4 is provided inside the base 1 to facilitate the removal of the instrument holder 2 from the device. The anti-loosening fixing mechanism 3 includes a spring 304 and a limiting block 305. The limiting block 305 is slidably connected to the inner wall surface of the base 1, and the spring 304 is fixedly installed on both sides of the inner wall of the instrument holder 2. The instrument holder 2 is placed on the upper surface of the base 1. By aligning the instrument holder 2 with the base 1 through the anti-loosening fixing mechanism 3, the positioning block 301 on the lower surface of the instrument holder is inserted into the positioning groove on the inner wall of the base. The sliding cooperation between the positioning block and the positioning groove achieves initial vertical positioning, ensuring that the instrument holder accurately falls to the center position of the base. When the instrument base 2 falls, the telescopic rods 302 on both sides of the inner wall move with the instrument base, causing the connecting plate 303 and the limiting block 305 to move closer to the inner wall of the base 1. When the limiting block 305 contacts the inner wall of the base, the spring undergoes elastic deformation due to compression, and a continuous horizontal thrust is applied to the limiting block through the connecting plate 303, causing the limiting block to engage with the limiting groove on the inner wall of the base. The telescopic rods 302 restrict the movement direction of the connecting plate 303, preventing the spring from shifting under force, ensuring that the limiting block and the limiting groove of the base are tightly engaged, forming a rigid limit in the horizontal direction, effectively resisting vibration and impact. By using the push-out mechanism 4, when it is necessary to remove the instrument base 2, the handwheel 406 can be rotated to drive the rotating shaft 401 and the gear 402 fixed on it to rotate synchronously. Gear 402 meshes with rack 403 on the inner wall of the base, converting rotational motion into horizontal linear motion of the rack. The rack 403 pushes push plate 405 to move through connecting rod 404. Push plate 405 moves and pushes limit block 305 to move and compress spring 304, causing limit block to gradually disengage from limit groove of base 1. When limit block completely exits limit groove, instrument base can be easily removed from base, completing disassembly.
[0032] Reference Figure 2 and Figure 3 In one aspect of this embodiment, a positioning block 301 is fixedly installed on the lower surface of the instrument base 2, the positioning block 301 is slidably connected to the inner wall surface of the base 1, and telescopic rods 302 are fixedly installed on both sides of the inner wall of the instrument base 2.
[0033] A connecting plate 303 is fixedly installed at one end of the telescopic rod 302, and a spring 304 is fixedly connected to one side of the inner wall of the connecting plate 303 at the other end. The spring 304 is movably wound around the surface of the telescopic rod 302. A limiting block 305 is fixedly installed on one side of the connecting plate 303. By aligning the instrument base 2 with the base 1, the positioning block 301 on the lower surface of the instrument base is inserted into the positioning groove on the inner wall of the base. The sliding engagement between the positioning block and the positioning groove achieves preliminary vertical positioning, ensuring that the instrument base is accurately placed in the center position of the base. When the instrument base 2 falls, the telescopic rods 302 on both sides of the inner wall move with the instrument base, causing the connecting plate 303 and the limiting block 305 to move closer to the inner wall of the base 1. When the limiting block 305 contacts the inner wall of the base, the spring undergoes elastic deformation due to compression, and a continuous horizontal thrust is applied to the limiting block through the connecting plate 303, causing the limiting block to engage with the limiting groove on the inner wall of the base. The telescopic rods 302 restrict the movement direction of the connecting plate 303, preventing the spring from shifting when under force, ensuring that the limiting block and the limiting groove of the base are tightly engaged, forming a rigid limit in the horizontal direction, effectively resisting vibration and impact.
[0034] Reference Figure 1 and Figure 4 In one aspect of this embodiment, a rotating shaft 401 is rotatably connected to one side of the base 1. The rotating shaft 401 passes through one side of the base 1, and a gear 402 is fixedly mounted on the surface of the rotating shaft 401.
[0035] A handwheel 406 is fixedly installed at one end of the rotating shaft 401, and a rack 403 is slidably connected to both ends of the inner wall of the base 1. The rack 403 meshes with the gear 402.
[0036] A connecting rod 404 is fixedly installed on one side of the rack 403, and a push plate 405 is fixedly installed on the other side of the connecting rod 404. The push plate 405 is slidably connected to the inner wall surface of the base 1. When it is necessary to remove the instrument base 2, the handwheel 406 is rotated, which drives the rotating shaft 401 and the gear 402 fixed thereon to rotate synchronously. The gear 402 meshes with the rack 403 on the inner wall of the base, converting the rotational motion into the horizontal linear motion of the rack. The rack 403 pushes the push plate 405 to move through the connecting rod 404. The movement of the push plate 405 pushes the limit block 305 to move and compresses the spring 304, causing the limit block to gradually disengage from the limit groove of the base 1. When the limit block is completely out of the limit groove, the instrument base can be easily removed from the base, completing the disassembly.
[0037] All electrical devices in this plan are powered by an external power source.
[0038] Working Principle: When using this device, align the instrument base 2 with the base 1, inserting the positioning block 301 on the lower surface of the instrument base into the positioning groove on the inner wall of the base. The sliding engagement between the positioning block and the positioning groove achieves initial vertical positioning, ensuring the instrument base accurately lands at the center of the base. As the instrument base 2 falls, the telescopic rods 302 on both sides of the inner wall move with the instrument base, driving the connecting plate 303 and the limiting block 305 closer to the inner wall of the base 1. When the limiting block 305 contacts the inner wall of the base, the spring undergoes elastic deformation due to compression, applying a continuous horizontal thrust to the limiting block through the connecting plate 303. This causes the limiting block to engage with the limiting groove on the inner wall of the base. The telescopic rods 302 restrict the movement direction of the connecting plate 303, preventing spring displacement under force and ensuring a tight engagement between the limiting block and the limiting groove of the base, forming a rigid horizontal limit that effectively resists vibration and impact. When it is necessary to remove the instrument base 2, rotate the handwheel 406, causing the rotating shaft 401 and the gear 402 fixed thereon to rotate synchronously. Gear 402 meshes with rack 403 on the inner wall of the base, converting rotational motion into horizontal linear motion of the rack. The rack 403 pushes push plate 405 to move through connecting rod 404. Push plate 405 moves and pushes limit block 305 to move and compress spring 304, causing limit block to gradually disengage from limit groove of base 1. When limit block completely exits limit groove, instrument base can be easily removed from base, completing disassembly.
