TECHNICAL FIELD
[0001] The application belongs to the technical field of freeze-dried microspheres, and particularly relates to a self-locking structure of a freeze-dried microsphere preparation and detection device. BACKGROUND
[0002] The freeze-dried microsphere technology is to mix a bioactive substance or a drug with a polymer material to prepare microspheres, freeze the microspheres, and then sublimate water in a vacuum to obtain a product. However, manual preparation of the microspheres is limited in size, and large-scale production is thus limited. Therefore, a freeze-dried microsphere preparation device is developed to greatly reduce the labor intensity of manual production and improve the production efficiency and product quality.
[0003] However, the existing freeze-dried microsphere preparation device needs to adjust the relative positions of a camera, a light source and a dropper before detection, so as to realize accurate detection and ensure the accuracy of the detection result. After adjusting the horizontal position and vertical height of the camera and the light source, an operator needs to perform a locking operation again to lock and fix the camera and the light source by using an independent locking mechanism (such as a screw rod). This undoubtedly greatly increases the complexity of the operation, and the independent locking mechanism also cannot guarantee the firmness of the locking.
[0004] Therefore, the self-locking structure of the freeze-dried microsphere preparation and detection device is provided. SUMMARY
[0005] The self-locking structure of the freeze-dried microsphere preparation and detection device is provided.
[0006] The self-locking structure of the freeze-dried microsphere preparation and detection device is provided. The self-locking assembly includes a cavity located in the center of one side wall of the vertical slide. A guide post is located in the center of one side inner wall of the cavity. A locking block is located on one side of one end of the guide post. The top and bottom of the locking block are provided with inclined grooves. Several toothed blocks are evenly spaced on the outer wall of the locking block away from the guide post. A matching guide groove is provided on the outer wall of the locking block near the outer side of the guide post. A spring is provided between the locking block and the cavity, located on the outer side of the guide post. A pressure rod is provided through the top and bottom of the vertical slide. A wedge is provided at one end of the pressure rod inside the cavity. The bottom of the wedge has an inclined surface. A pressure plate is provided at the other end of the pressure rod on the outer side of the vertical slide. A spring is provided between the pressure plate and the vertical slide near the outer side of the pressure rod.
[0007] Furthermore, a connecting rod is provided on the outer wall of the vertical slide table on the side away from the vertical slide rail. Two toothed plates are symmetrically arranged on the top of the connecting rod, and two sliding covers are symmetrically slidably connected on the outer wall of the connecting rod. A self-locking component is provided on the sliding cover.
[0008] Furthermore, the self-locking component two includes two rotating shafts that pass through and rotate symmetrically on the side wall of the sliding cover. A gear is provided between the two rotating shafts. One end of one of the rotating shafts is provided with a mating platform one near the outer side of the sliding cover. A plurality of mating grooves one are axially and evenly spaced on one side of the mating platform one. An extrusion column is provided through the sliding cover near the position directly below the rotating shaft on one side of the outer wall of the sliding cover. A disc is provided near the outer side of the sliding cover at one end of the extrusion column. A spring three is provided between the disc and the sliding cover. A U-shaped rod is provided at the center position of the outer wall of the disc away from the extrusion column. A mating platform two is provided at one end of the U-shaped rod. A plurality of mating grooves two are axially and evenly spaced on one side of the mating platform two.
[0009] Furthermore, a camera mounting bracket and a light source plate are respectively provided at the bottom of the two sliding covers. A camera is mounted on the camera mounting bracket, a light source is mounted on the light source plate, and a base is mounted at the bottom of the horizontal slide rail.
[0010] Furthermore, the cross-sections of the horizontal and vertical slide rails are isosceles trapezoidal structures, and isosceles trapezoidal grooves that match and slide with the horizontal and vertical slide rails are respectively provided on one side wall of the horizontal and vertical slide tables. By adopting the above technical solution, the isosceles trapezoidal horizontal and vertical slide rails and the slide groove can form a mutually constrained structure, which not only ensures the stability of the horizontal and vertical slide tables sliding on the horizontal and vertical slide rails respectively, but also prevents the horizontal and vertical slide tables from detaching from the horizontal and vertical slide rails.
[0011] Furthermore, a toothed groove matching and fitting the toothed block is formed on one outer wall of the toothed plate, and the toothed block and the toothed groove are interlocked. By adopting the above technical solution, the interlocking between tooth block one and tooth plate one forms a support structure, and then the locking block on one side of tooth block one is supported by tooth plate one, so as to ensure that the locking block is at the adjusted vertical height, thereby realizing the adjustment of the vertical slide height position.
[0012] Furthermore, one inner wall of the inclined groove is horizontal to the inclined surface, and the inclined groove is in close contact with the inclined surface; By adopting the above technical solution, the wedge moves vertically toward the lock block through the matching inclined groove and inclined surface. Under the horizontal guidance of the guide post and guide groove, the vertical force is converted into a horizontal force, which causes the lock block to move away from the tooth block one. The tooth block one on the lock block disengages from the tooth block one, realizing the unlocking of the self-locking component one. This allows the vertical slide to move vertically along the vertical slide rail.
[0013] Furthermore, four round rods are symmetrically arranged on the outer wall of the pressure plate facing the vertical slide, and round holes matching the round rods are opened on the outer wall of the vertical slide. By adopting the above technical solution, the vertical guide structure formed by the cooperation of the round rod and the round hole can make the pressure plate move vertically toward the vertical slide, thereby ensuring the stability of the pressure rod movement. The pressure plate can increase the contact surface during extrusion.
[0014] Furthermore, the toothed plate and the gear are connected by meshing teeth; By adopting the above technical solution, when the gear rotates through meshing connection, the gear moves and rotates along the toothed plate in a straight line, thereby causing the sliding cover to move horizontally in a straight line along the connecting rod, thus realizing the adjustment of the horizontal position of the sliding cover.
[0015] Furthermore, the first and second mating grooves engage with each other; By adopting the above technical solution, the interlocking groove 1 and the interlocking groove 2 can make the interlocking platform 1 and the interlocking platform 2 tightly inserted, preventing the interlocking platform 1 from rotating, and achieving the self-locking effect after adjusting the horizontal position of the sliding cover.
[0016] The beneficial effects of this invention are as follows: This invention utilizes a self-locking component to achieve two main functions: firstly, it enables the vertical slide to move vertically along the vertical rail, allowing for adjustment of the camera and light source at different heights; secondly, it automatically locks the vertical slide after vertical adjustment, ensuring its stability. Adjustment and locking can be achieved in a single step, greatly simplifying the operation. The advantages become more apparent with repeated adjustments. Furthermore, the interlocking support structure ensures the stability after self-locking, preventing vertical displacement of the vertical slide.
[0017] 2. The present invention, through the second self-locking component, enables the sliding cover to move horizontally on the connecting rod, thereby adjusting the horizontal position of the camera and the light source. On the other hand, it enables the automatic locking of the sliding cover after horizontal adjustment, achieving self-locking of the sliding cover position and ensuring the stability of the sliding cover position. Adjustment and locking can be achieved in only one step, greatly simplifying the operation steps. The advantages become more obvious with repeated adjustments. Furthermore, the interlocking support structure can ensure the firmness after self-locking and prevent the sliding cover from shifting horizontally.

The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0021] Example 1 Reference Figures 1-4 This invention proposes a self-locking structure for a freeze-dried microsphere preparation and detection device, comprising a horizontal slide rail 1, a horizontal slide table 2 slidably connected to the top of the horizontal slide rail 1, a vertical plate 3 disposed on the top of the horizontal slide table 2, a vertical slide rail 4 disposed on one outer wall of the vertical plate 3, toothed plates 41 embedded at the center of the top of the horizontal slide rail 1 and the center of one outer wall of the vertical slide rail 4, and a vertical slide table 5 slidably connected to the outer wall of the vertical slide rail 4. The cross-sections of the horizontal slide rail 1 and the vertical slide rail 4 are as follows: The isosceles trapezoidal structure has isosceles trapezoidal grooves on one side wall of the horizontal slide table 2 and the vertical slide table 5, which are matched and slide with the horizontal slide rail 1 and the vertical slide rail 4, respectively. The isosceles trapezoidal horizontal slide rail 1 and the vertical slide rail 4 can form a mutually constrained structure with the grooves, which not only ensures the stability of the horizontal slide table 2 and the vertical slide table 5 sliding on the horizontal slide rail 1 and the vertical slide rail 4 respectively, but also prevents the horizontal slide table 2 and the vertical slide table 5 from disengaging from the horizontal slide rail 1 and the vertical slide rail 4. The vertical slide table 5 is equipped with a self-locking component 6. The self-locking assembly 6 includes a cavity 61 located at the center of one side wall of the vertical slide 5. A guide post 62 is positioned at the center of one side inner wall of the cavity 61. A locking block 63 is positioned at one end of the guide post 62. Inclined grooves 631 are provided at both the top and bottom of the locking block 63. A plurality of toothed blocks 632 are evenly spaced on the outer wall of the locking block 63 away from the guide post 62. A toothed groove matching and fitting the toothed blocks 632 is provided on the outer wall of one side of the toothed plate 41. The toothed blocks 632 and the toothed grooves are engaged and connected. The engagement between the toothed blocks 632 and the toothed plate 41 enables the locking mechanism to lock. This forms a supporting structure, which in turn uses the toothed plate 41 to support the locking block 63 on one side of the toothed block 632, ensuring that the locking block 63 is at the adjusted vertical height, thereby realizing the adjustment of the height position of the vertical slide table 5. A matching guide groove 64 is provided on one side of the outer wall of the locking block 63 near the outer side of the guide post 62, and a spring 65 is provided between the locking block 63 and the cavity 61 and located on the outer side of the guide post 62. Pressure rods 66 are provided through the top and bottom of the vertical slide table 5, and a wedge 67 is provided at one end of the pressure rod 66 inside the cavity 61. The bottom of the wedge 67 has an inclined surface 671. One inner wall of the inclined groove 631 is horizontal to the inclined surface 671, and the inclined groove 631 fits tightly with the inclined surface 671. Through the fitting inclined groove 631 and inclined surface 671, when the wedge 67 moves vertically toward the locking block 63, under the horizontal guidance of the guide post 62 and guide groove 64, the vertical force is converted into a horizontal force, thereby causing the locking block 63 to move away from the tooth block 632. The tooth block 632 on the locking block 63 disengages from the tooth block 632, realizing the unlocking of the self-locking component 6, and thus allowing the vertical slide 5 to move along... The vertical slide rail 4 moves vertically. The other end of the pressure rod 66 is located on the outer side of the vertical slide table 5, where a pressure plate 68 is provided. Four round rods are symmetrically arranged on the outer wall of the pressure plate 68 facing the vertical slide table 5. The outer wall of the vertical slide table 5 is provided with round holes that match the round rods. Through the vertical guide structure formed by the cooperation of the round rods and round holes, the pressure plate 68 can move vertically toward the vertical slide table 5, thereby ensuring the stability of the movement of the pressure rod 66. The pressure plate 68 can increase the contact surface during extrusion. A spring 69 is provided between the pressure plate 68 and the vertical slide table 5 near the outer side of the pressure rod 66. To achieve vertical height adjustment of the camera 11 and light source 13, and to ensure stability of their positions through self-locking after height adjustment, in this embodiment, when adjusting the height of the vertical slide 5, the operator pushes or presses down the pressure plate 68, compressing the spring 69. In the vertical guide structure formed by the cooperation of the round rod and the round hole, the pressure plate 68 stably pulls the pressure rod 66 upwards or downwards. As the pressure rod 66 moves, the wedge 67 at one end of the pressure rod 66 moves towards the locking block 63. The wedge 67 moves within the inclined groove 631, through... The inclined groove 631 and inclined surface 671 fit together so that when the wedge 67 moves vertically toward the locking block 63, and under the horizontal guidance of the guide post 62 and the guide groove 64, the vertical force is converted into a horizontal force, which causes the locking block 63 to move away from the tooth block 632, the spring 65 is compressed, and the tooth block 632 on the locking block 63 disengages from the tooth block 632, realizing the unlocking of the self-locking component 6. At this time, the vertical slide 5 can be pushed to move vertically along the vertical slide rail 4 to realize the adjustment of the height of the camera 11 and the light source 13. After adjustment, the force on the pressure plate 68 is released. Under the restoring force of spring 65 and spring 69, spring 65 pushes the locking block 63 toward the toothed plate 41. The toothed block 632 on one side of the locking block 63 inserts into the toothed groove on the toothed plate 41 to form a meshing connection. The meshing between the toothed block 632 and the toothed plate 41 forms a support structure. The toothed plate 41 then supports the locking block 63 on one side of the toothed block 632, ensuring that the locking block 63 is at the adjusted vertical height and ensuring the stability of the vertical slide 5 after adjustment, thus achieving the self-locking effect.
[0022] Example 2 Reference Figure 1 , Figures 5-7 Based on the above embodiments, this invention also proposes a self-locking structure for a freeze-dried microsphere preparation and detection device, including a connecting rod 7 disposed on the outer wall of the vertical slide table 5 away from the vertical slide rail 4, two toothed plates 71 symmetrically disposed on the top of the connecting rod 7, and two sliding covers 8 symmetrically slidably connected on the outer wall of the connecting rod 7, with a self-locking component 9 disposed on the sliding cover 8.
[0023] The self-locking assembly 29 includes two rotating shafts 91 that penetrate and symmetrically rotate on the side wall of the sliding cover 8. A gear 92 is provided between the two rotating shafts 91. The gear plate 21 and the gear 92 are connected by gear teeth meshing. When the gear 92 rotates, it moves linearly along the gear plate 21 and rotates, thereby causing the sliding cover 8 to move horizontally along the connecting rod 7, realizing the adjustment of the horizontal position of the sliding cover 8. One end of one of the rotating shafts 91 is provided with a mating platform 93 near the outer side of the sliding cover 8. A number of mating grooves 94 are axially spaced at equal intervals on one side end of the mating platform 93. A through-hole is provided on one side outer wall of the sliding cover 8 near the position directly below the rotating shaft 91. A pressing column 95 is provided. A disc 97 is provided at one end of the pressing column 95 near the outer side of the sliding cover 8. A spring 96 is provided between the disc 97 and the sliding cover 8. A U-shaped rod 98 is provided at the center of the outer wall of the disc 97 away from the pressing column 95. A mating platform 99 is provided at one end of the U-shaped rod 98. Several mating grooves 991 are axially and evenly spaced on one side of the mating platform 99. The mating grooves 94 and 991 engage with each other. Through the engagement of the mating grooves 94 and 991, the mating platforms 93 and 99 can be tightly inserted, preventing the mating platform 93 from rotating, and achieving the self-locking effect after the horizontal position of the sliding cover 8 is adjusted. To achieve horizontal adjustment of the camera 11 and the light source 13, and to ensure stability of their position after horizontal adjustment, in this embodiment, when the sliding cover 8 is pushed to move horizontally, the sliding cover 8 slides horizontally along the connecting rod 7. Under the meshing connection of the gear 92 and the second gear plate 71, the gear 92 rotates inside the sliding cover 8. As the gear 92 rotates, the rotating shaft 91 at one end of the gear 92 pulls the mating platform 93 to rotate, and the mating groove 94 on the mating platform 93 moves axially. With the axial movement of the mating groove 94 and the meshing between the mating groove 94 and the second mating groove 991, the second mating platform 99 moves horizontally in a reciprocating manner. Under the connection of the U-shaped rod 98, the disc 97 stretches the third spring 96, and the extrusion column 95 moves horizontally in a reciprocating manner. At this time, the extrusion column 95 intermittently contacts and extrudes the connecting rod 7, using the extrusion force to achieve self-locking of the sliding cover 8 on the connecting rod 7, ensuring the stability of the sliding cover 8 after adjustment, and achieving the self-locking effect.
[0024] The bottom of the two sliding covers 8 are respectively provided with a camera mounting bracket 10 and a light source plate 12. The camera 11 is mounted on the camera mounting bracket 10, the light source 13 is mounted on the light source plate 12, and the base 14 is mounted on the bottom of the horizontal slide rail 1. To detect the volume, volume accuracy, and spray efficiency of freeze-dried microspheres, the system can be adaptively adjusted according to the needs of the application scenario to meet the detection standards. It can also adjust the horizontal position and vertical height of the camera 11 and the light source 13, making it easy for operators to precisely control the relative position of the camera 11 and the dropper, thereby achieving accurate detection and ensuring the accuracy of the detection results.
[0025] Working principle: When adjusting the horizontal position and vertical height of the camera 11 and the light source 13, the operator first pushes or presses down the pressure plate 68, compresses the spring 69, and the pressure plate 68 pulls the pressure rod 66 to move up or down. The wedge 67 at one end of the pressure rod 66 moves toward the locking block 63. The wedge 67 moves inside the inclined groove 631. Under the horizontal guidance of the inclined groove 631 and the inclined surface 671, as well as the guide post 62 and the guide groove 64, the vertical force is converted into a horizontal force, the spring 65 is compressed, and the toothed block 632 on the locking block 63 disengages from the toothed block 632, thereby unlocking the self-locking component 6. At this time, the vertical slide table 5 can be pushed to move vertically along the vertical slide rail 4 to achieve the adjustment of the height of the camera 11 and the light source 13. Then, the sliding cover 8 is pushed horizontally, and the sliding cover 8 slides horizontally along the connecting rod 7. The gear 92 rotates inside the sliding cover 8, and the rotating shaft 91 at one end of the gear 92 pulls the mating platform 93 to rotate. The mating groove 94 on the mating platform 93 moves axially. With the axial movement of the mating groove 94 and the engagement between the mating groove 94 and the mating groove 991, the mating platform 99 moves horizontally in a reciprocating manner. Under the connection of the U-shaped rod 98, the disc 97 stretches the spring 96, and the extrusion column 95 moves horizontally in a reciprocating manner. At this time, the extrusion column 95 intermittently contacts and extrudes the connecting rod 7, using the extrusion force to achieve self-locking of the sliding cover 8 on the connecting rod 7, ensuring the stability of the sliding cover 8 in the adjusted position, and achieving the self-locking effect.
