[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 3 As shown, the present invention provides a stopper device for a freeze dryer, comprising a housing 1, a placement groove 2, a movable rod 3, a hydraulic cylinder 4, a pressure plate 5, and a placement plate 6. The placement groove 2 is located on the front of the housing 1. The top of the inner wall of the hydraulic cylinder 4 is fixedly connected to the top of the inner wall of the housing 1. The top of the pressure plate 5 is movably connected to the piston end of the hydraulic cylinder 4. The bottom of the placement plate 6 is movably connected to the bottom of the inner wall of the placement groove 2. A limiting block 7 is movably sleeved on the bottom of the surface of the movable rod 3. A limiting groove 8 is opened on the inner side of the top of the limiting block 7. The inner wall of the limiting groove 8 is slidably connected to the surface of the placement plate 6. A connecting rod 9 is movably sleeved on the top of the surface of the movable rod 3. A slot 10 is opened on the inner side of the connecting rod 9. A locking strip 11 is slidably connected to the inner wall of the slot 10. The inner side of the locking strip 11 is fixedly connected to both sides of the pressure plate 5. Fixing components 12 are opened on both sides of the bottom of the inner wall of the slot 10 and both sides of the top of the locking strip 11. A storage component 13 is opened on the bottom of the front of the housing 1.
[0023] refer to Figure 3 The fixing component 12 includes a fixing groove 121, which is opened on both sides of the top of the inner wall of the slot 10 and on both sides of the top of the slot 10. The inner wall of the slot 10 is threaded with a fixing rod 122.
[0024] As a technical optimization of this utility model, by setting a fixing component 12, when the user moves the card strip 11 completely into the card slot 10, the fixing groove 121 at the top of the card strip 11 is connected to the fixing groove 121 at the bottom of the inner wall of the card slot 10. Then, the bottom of the fixing rod 122 is aligned with the fixing groove 121. At this time, the fixing rod 122 is rotated so that the fixing rod 122 is completely moved into the fixing groove 121. The fixing rod 122 can be used to fix the card strip 11 and the connecting rod 9 together, while preventing the pressure plate 5 from coming off the connecting rod 9, thereby achieving the effect of facilitating the user to install the pressure plate 5.
[0025] refer to Figure 2 The storage component 13 includes a storage slot 131, which is located at the bottom of the front of the box body 1. Placement strips 132 are fixedly connected to both sides of the inner wall of the storage slot 131. Several placement strips 132 are provided and are evenly distributed. A connecting groove 133 is provided on the inner side of the placement strip 132. The inner wall of the connecting groove 133 is slidably connected to the surface of the card strip 11.
[0026] As a technical optimization of this utility model, by setting up the storage component 13, when the user needs to change different styles of pressure plates 5, the corresponding pressure plate 5 inside the placement slot 2 can be taken out and fixed with the connecting rod 9. Then, the clips 11 on both sides of the pressure plate 5 that are not needed are aligned with the connecting slot 133 inside the placement strip 132. Then, the pressure plate 5 is moved towards the box body 1, so that the clips 11 are completely moved into the inside of the connecting slot 133. The connecting slot 133 can restrict the movement direction of the clips 11, so that the pressure plate 5 is placed more stably inside the storage slot 131, thereby achieving the effect of convenient storage.
[0027] refer to Figure 2 A shielding groove 14 is provided on the front side of the top of the placement strip 132, and a shielding block 15 is slidably connected to the inner wall of the shielding groove 14.
[0028] As a technical optimization of this utility model, by setting a blocking groove 14 and a blocking block 15, when the user completely moves the card strip 11 into the interior of the connecting groove 133, the blocking block 15 is taken out, the bottom of the blocking block 15 is aligned with the blocking groove 14, and then the blocking block 15 is moved downward so that the blocking block 15 is completely moved into the interior of the blocking groove 14. At this time, the blocking block 15 can block the connecting groove 133, so that the card strip 11 cannot move out of the connecting groove 133, thus preventing the card strip 11 from automatically detaching from the connecting groove 133, thereby achieving the effect of restricting the movement of the card strip 11.
[0029] refer to Figure 2 A storage box 16 is slidably connected to the bottom of the inner wall of the storage slot 2. Slide grooves 17 are provided on the bottom of both sides of the inner wall of the storage slot 131. A slider 18 is slidably connected to the inner wall of the slide groove 17. The inner side of the slider 18 is fixedly connected to the bottom of both sides of the storage box 16.
[0030] As a technical optimization of this utility model, by setting up a storage box 16, a sliding groove 17 and a slider 18, when the user needs to find the corresponding part, the storage box 16 is moved towards the front of the box 1, which causes the slider 18 to move towards the front side of the inner wall of the sliding groove 17. The sliding groove 17 can limit the movement direction and final position of the slider 18, thereby making the storage box 16 move stably, thus achieving the effect of assisting in the placement of parts.
[0031] refer to Figure 2 The piston end of the hydraulic cylinder 4 is fixedly connected to a mounting plate 19. A magnetic block 20 is embedded in the bottom of the mounting plate 19. The bottom of the magnetic block 20 is magnetically attracted to the top of the pressure plate 5. The mounting plate 19 is fixedly connected to the top of the pressure plate 5 by bolts.
[0032] As a technical optimization of this utility model, by setting up the mounting plate 19 and the magnetic block 20, when the user connects the pressure plate 5 to the connecting rod 9, the pressure plate 5 is moved upward so that the top of the pressure plate 5 contacts the bottom of the mounting plate 19. The magnetic block 20 can be used to attract the pressure plate 5 to the bottom of the mounting plate 19, which is convenient for the user to fix it with bolts later. This avoids the situation where the pressure plate 5 moves downward automatically and is difficult to connect with the hydraulic cylinder 4, thereby achieving the effect of assisting the installation of the pressure plate 5.
[0033] refer to Figure 3 An auxiliary block 21 is fixedly connected to the top of the fixed rod 122, and an auxiliary strip 22 is fixedly connected to the surface of the auxiliary block 21. Several auxiliary strips 22 are provided and are distributed in a ring at equal intervals.
[0034] As a technical optimization of this utility model, by setting auxiliary blocks 21 and auxiliary strips 22, when the user needs to rotate the fixed rod 122, the auxiliary blocks 21 can increase the contact area between the user and the fixed rod 122, making it more convenient for the user to rotate the fixed rod 122. Furthermore, the multiple auxiliary strips 22 can increase the friction between the user and the auxiliary blocks 21, preventing the user from slipping when rotating the auxiliary blocks 21, thereby achieving the effect of assisting the rotation of the fixed rod 122.
[0035] The working principle and usage process of this utility model are as follows: During use, the limiting block 7 facilitates the user's installation of the placement plate 6, preventing it from moving arbitrarily. The connecting rod 9 facilitates the user's installation of the pressure plate 5, allowing for the replacement of pressure plates 5 with different specifications to accommodate different sizes of vials. When the user moves the clip 11 completely into the slot 10, the fixing groove 121 at the top of the clip 11 connects with the fixing groove 121 at the bottom of the inner wall of the slot 10. The bottom of the fixing rod 122 is then aligned with the fixing groove 121. Rotating the fixing rod 122 completely moves it into the fixing groove 121, fixing the clip 11 and the connecting rod 9 together, preventing the pressure plate 5 from detaching from the connecting rod 9. When the user connects the pressure plate 5 to the connecting rod 9, the pressure plate 5 is moved upwards until its top contacts the bottom of the mounting plate 19. The magnetic block 20 attaches the pressure plate 5 to the bottom of the mounting plate 19, facilitating subsequent bolt fixation and preventing... When the pressure plate 5 moves downward automatically and becomes difficult to connect with the hydraulic cylinder 4, if the user needs to replace it with a different style of pressure plate 5, the corresponding pressure plate 5 inside the placement slot 2 can be taken out and fixed to the connecting rod 9. Then, the retaining strips 11 on both sides of the pressure plate 5 that are not in use should be aligned with the connecting groove 133 inside the placement strip 132. Then, the pressure plate 5 should be moved towards the housing 1 so that the retaining strips 11 are completely moved into the interior of the connecting groove 133. The connecting groove 133 can restrict the movement direction of the retaining strips 11, making the pressure plate 5 more stable. Placed inside the storage slot 131, when the user has completely moved the clip 11 into the connecting slot 133, the blocking block 15 is then removed, the bottom of the blocking block 15 is aligned with the blocking slot 14, and the blocking block 15 is moved downwards so that the blocking block 15 is completely moved into the blocking slot 14. At this time, the blocking block 15 can block the connecting slot 133, preventing the clip 11 from moving out of the connecting slot 133, thus avoiding the situation where the clip 11 automatically detaches from the connecting slot 133, thereby achieving the effect of convenient replacement.
[0036] In summary, the stoppering device of this freeze dryer, by setting a limiting block 7 and a connecting rod 9, allows the user to easily install the placement plate 6, preventing it from moving arbitrarily. The connecting rod 9 facilitates the user's installation of the pressure plate 5, allowing for easy replacement of different sizes of pressure plates 5. This enables the device to accommodate different sizes of vials, solving the problem of the lack of a structure that allows users to easily replace different pressure plates, thus preventing the stoppering device from pressing vials of different sizes and shapes, reducing the equipment's versatility, and increasing the cost for companies to replace equipment due to changes in product specifications.
