Detailed Description of the Preferred Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4, a pathological detection sample fixing device, comprising a base 1, a fixing device, a height adjusting device and a rotation adjusting device. The top end of the base 1 is provided with an adjusting seat 2 through the rotation adjusting device, and the top end of the adjusting seat 2 is provided with the fixing device through the height adjusting device. The rotation adjusting device includes a worm gear 3, a worm 4 and a first motor 5. A cavity 6 is formed in the base 1, and the worm gear 3 is rotatably installed in the cavity 6. One end of the worm gear 3 is meshed with the worm 4, and one end of the worm 4 penetrates through the side wall of the base 1 and is provided with the first motor 5. The fixing device includes a rectangular block 7, a rectangular groove 8, a bidirectional screw 9, a second motor 10, a slider 11, a fixing plate 12, a fixing groove 13 and a pressure sensor 14. A rectangular groove 8 is formed in one side wall of the rectangular block 7, and the bidirectional screw 9 is rotatably installed in the rectangular groove 8. One end of the bidirectional screw 9 penetrates through the side wall of the rectangular groove 8 and is provided with the second motor 10. Sliders 11 are installed at both the left and right ends of the bidirectional screw 9. Fixing plates 12 are fixedly installed at the ends of the two sliders 11 away from the rectangular groove 8. Fixing grooves 13 are formed between the two fixing plates 12. A pressure sensor 14 is installed on the inner side wall of one of the fixing grooves 13. The pressure sensor 14 is electrically connected to the second motor 10. In this embodiment, during use, after placing the detection sample in the sample bottle and then placing it on the adjusting seat 2, the operator starts the second motor 10. The second motor 10 starts to rotate the bidirectional screw 9. The rotation of the bidirectional screw 9 will cause the sliders 11 installed on it to move inwards or outwards, driving the fixing plate 12 to approach or move away from the sample bottle. When the fixing plate 12 approaches the sample bottle, the pressure sensor 14 detects the pressure change and feeds it back to the second motor 10. When the pressure reaches the preset value, the operation of the second motor 10 is stopped, and the fixing of the sample bottle is completed. The design of the bidirectional screw 9 enables the fixing plate 12 to adapt to sample bottles of different diameters. Through the cooperation of the bidirectional screw 9 and the pressure sensor 14, it can ensure that the pressure applied to the sample bottle is uniform, preventing damage to the sample bottle. The pressure sensor 14 is linked with the motor to achieve automatic control of the fixing force, avoiding human error. If the horizontal angle of the sample bottle needs to be adjusted during the detection process, start the first motor 5. The first motor 5 drives the worm 4 to rotate. Due to the meshing connection between the worm 4 and the worm gear 3, the rotation of the worm 4 will drive the worm gear 3 to rotate. The rotation of the worm gear 3 will cause the adjusting seat 2 installed on it to rotate relative to the base 1, thereby realizing the angle adjustment of the fixing device. The worm gear 3 and worm 4 transmission has a self-locking function, which can prevent the adjusting seat 2 from rotating by itself without power input and can adjust the angle arbitrarily according to needs, suitable for various detection requirements.

[0026] During the actual use process, to further facilitate the adjustment of the height of the fixing device, in this embodiment, the height adjustment device includes a fixing frame 15, a threaded rod 16, a square nut 17, and a third motor 18. One end of the top wall of the adjustment seat 2 is fixedly installed with the fixing frame 15 with a side opening. The threaded rod 16 is rotatably installed in the fixing frame 15. One end of the threaded rod 16 penetrates through the top wall of the fixing frame 15 and is installed with the third motor 18. The square nut 17 is threadedly installed on the threaded rod 16. The side wall of the square nut 17 is fixedly connected to one end of the rectangular block 7 away from the rectangular groove 8. Start the third motor 18, and the motor starts to rotate the threaded rod 16. As the threaded rod 16 rotates, the square nut 17 moves upward or downward along the thread direction. The movement of the square nut 17 drives the rectangular block 7 to rise or fall synchronously, thereby realizing the change of the height of the fixing device. When the fixing device reaches the predetermined height, the third motor 18 stops operating, completing a height adjustment process, which is convenient for adjusting to the optimal clamping and fixing position according to the sample bottle.

[0027] During the actual use process, to further limit the two groups of sliders 11, in this embodiment, a limiting block 19 is installed in the middle of the rectangular groove 8. In some cases, if the slider 11 moves beyond the predetermined range, it may cause unnecessary pressure on the sample bottle, resulting in damage to the sample bottle. The presence of the limiting block 19 can prevent the slider 11 from excessively compressing the sample bottle and protect the sample bottle from damage.

[0028] During the actual use process, to further improve the placement stability of the base 1, in this embodiment, an anti-slip pad is installed on the bottom wall of the base 1. The anti-slip pad can increase the friction between the base 1 and the placement surface, preventing the device from sliding or tilting due to slight collisions or vibrations during operation. This is crucial for ensuring the stability of the sample fixing device during use, especially in a laboratory environment. Smooth operation is very important for protecting sensitive samples and ensuring the accuracy of test results.

[0029] During the actual use process, to further adapt to different sizes of test sample bottles, in this embodiment, the fixing groove 13 is designed in a V shape. The V-shaped design can naturally adapt to sample bottles with different diameters and fix the sample bottle through the clamping force on both sides. Even if the size of the sample bottle is different, it can maintain a stable fixed state. The V-shaped fixing groove 13 can also naturally guide the sample bottle to the center position of the groove, ensuring that the sample bottle does not deviate from the set fixing point, thereby improving the position accuracy of the sample bottle during fixing.

[0030] During the actual use process, to further prevent the fixing groove 13 from damaging the outer surface of the detection sample bottle. In this embodiment, rubber pads are installed in both groups of the fixing grooves 13. The rubber pads have good elasticity and softness, and can play a buffering role when fixing the sample bottle, avoiding direct contact of hard materials (such as metal or plastic) with the outer surface of the sample bottle, which may scratch or damage it. This is crucial for ensuring the integrity of the sample bottle, especially when the sample bottle is made of fragile materials (such as glass).

[0031] During the actual use process, to further ensure the stability and accuracy of the operation of the first motor 5, the second motor 10, and the third motor 18. In this embodiment, the first motor 5, the second motor 10, and the third motor 18 are all servo motors. The servo motor can perform position, speed, and torque control with high precision. The servo motor adopts closed-loop control and has good stability, which can avoid problems such as stall and vibration, and ensure the stability and accuracy of the operation of the first motor 5, the second motor 10, and the third motor 18.

[0032] During the actual use process, to further facilitate the control of the operating states of the three motors. In this embodiment, a controller 20 is installed on the side wall of the base 1. The controller 20 is electrically connected to the first motor 5, the second motor 10, and the second motor 10. Control buttons 21 are installed on the controller 20. The controller 20 centrally manages the operating states of the three motors, making the operation more intuitive and convenient. The operator can coordinate the actions of all motors through a central control point, reducing the operation complexity.

[0033] To illustrate in detail the possible application scenarios, technical principles, specific implementable solutions, achievable purposes and effects of this application, etc., the following will be described in detail with reference to the specific embodiments listed and in conjunction with the drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of this application, so they are only examples and cannot be used to limit the protection scope of this application.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
