Description

Technical Field

[0001] This utility model relates to the field of syringe filter technology, and in particular to an anti-tipping shelf for syringe filters. Background Technology

[0002] A syringe filter is a commonly used miniature filtration device in laboratories. It typically consists of a polypropylene shell, a filter membrane, and a Luer connector. It needs to be used with a syringe to achieve rapid filtration of liquids or gases through manual injection or negative pressure aspiration. A syringe filter holder is a support device specifically designed for storing syringe filters in use. It usually consists of a base, a placement plate, and a fixing structure. It can be placed independently on the lab bench or embedded in equipment to temporarily fix the filter and prevent movement, contamination, or liquid backflow.

[0003] Currently, storage racks for syringe filters typically rely solely on basic snap-fit ​​mechanisms to restrict their position. When the rack is subjected to external impact or accidental collision, the syringe filters stored within are prone to tilting or even dislodging, which will adversely affect the storage efficiency of the rack. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of poor limiting effect during storage and is prone to tipping over due to external factors. To this end, we propose an anti-tipping shelf for syringe filters.

[0005] To achieve the above objectives, this application adopts the following technical solution: an anti-tipping shelf for a syringe filter, comprising a frame base: a fixed frame is installed at the top of the frame base, multiple placement plates are installed at the front end of the fixed frame, a limit cover is installed at the top of the placement plate, a number of placement grooves are opened at the top of the placement plate, a number of mating grooves that cooperate with the placement grooves are opened at the bottom of the limit cover, snap-fit ​​sleeves are fixedly connected to both sides of the limit cover, pressing grooves are opened on both sides of the placement plate, a spring spring is fixedly connected inside the pressing groove, a pressing block is fixedly connected to the end of the spring spring, and the snap-fit ​​sleeves and the inside of the pressing groove are slidably connected to the pressing block.

[0006] Preferably, the surface of the pressing block is provided with an angle, and the direction of the angle is towards the snap-fit ​​direction of the snap-fit ​​sleeve.

[0007] Preferably, the front and rear ends of the pressing groove are provided with stop grooves, and the front and rear ends of the pressing block are fixedly connected with stop blocks, and the inside of the stop groove is slidably connected with the stop blocks.

[0008] Preferably, a rubber contact pad is installed inside the placement groove.

[0009] Preferably, the top of the placement plate is equipped with multiple elastic sheets, and the top of the elastic sheets abuts against the bottom of the limiting cover.

[0010] Preferably, guide grooves are provided at both the front and rear ends of the placement plate, and guide posts are fixedly connected to both the front and rear ends of the limiting cover, with the inside of the guide grooves slidably connected to the guide posts.

[0011] Preferably, both the placement plate and the limiting cover are coated with Teflon coating.

[0012] The technical effects and advantages of this utility model are as follows: In this utility model, when the operator needs to use the syringe filter, the two pressing blocks are pressed inward simultaneously to move them into the pressing groove, thereby releasing the limiting cover from the placement plate. At this time, the limiting cover can be removed from the placement plate, and the syringe filter can be taken out for use. After taking it out, the limiting cover is aligned with the placement plate and snapped in, and the pressing blocks are aligned with the snap-fit ​​sleeve and snapped in. After snapping in, the elastic force of the spring drives the pressing blocks to be firmly snapped in the snap-fit ​​sleeve, thereby achieving quick installation of the limiting cover after the syringe filter is taken out. By installing a limiting cover that can be easily removed and fixed on the surface of the placement plate, the syringe filter can have a stable limiting effect during storage and placement, so that it will not tip over due to external collisions, thereby effectively improving the stability of the syringe filter during placement.

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0016] Reference Figures 1-4 As shown, this utility model provides a technical solution: an anti-tipping shelf for a syringe filter, including a frame base 1; a fixing frame 2 is installed at the top of the frame base 1, and multiple placement plates 3 are installed at the front end of the fixing frame 2. A limit cover 4 is installed at the top of the placement plate 3, and several placement grooves 5 are opened at the top of the placement plate 3. Several mating grooves 6 that cooperate with the placement grooves 5 are opened at the bottom end of the limit cover 4. A snap-fit ​​sleeve 7 is fixedly connected to both sides of the limit cover 4. A pressing groove 8 is opened on both sides of the placement plate 3. A spring spring 9 is fixedly connected inside the pressing groove 8, and a pressing block 10 is fixedly connected to the end of the spring spring 9. The snap-fit ​​sleeve 7 and the inside of the pressing groove 8 are slidably connected to the pressing block 10. When the operator needs to use the syringe filter, the two pressing blocks 10 are pressed inward simultaneously. Move it to the inside of the pressing groove 8 to release the limiting cover 4 from the placement plate 3. Then the limiting cover 4 can be removed from the placement plate 3 and the syringe filter can be taken out for use. After taking it out, align the limiting cover 4 with the placement plate 3 and snap it in, and align the pressing block 10 with the snap-fit ​​sleeve 7 and snap it in. After snapping, the elastic force of the spring spring 9 drives the pressing block 10 to be firmly snapped in the snap-fit ​​sleeve 7, thereby achieving quick installation of the limiting cover 4 after the syringe filter is taken out. By installing a limiting cover 4 that can be easily removed and fixed on the surface of the placement plate 3, the syringe filter can have a stable limiting function during storage and placement, so that it will not tip over due to external collisions, thereby effectively improving the stability of the syringe filter during placement.

[0017] Reference Figure 4 As shown in this embodiment: the surface of the pressing block 10 is provided with an angle 11, and the direction of the angle 11 is towards the snap-fit ​​direction of the snap-fit ​​sleeve 7. By setting the angle 11, when it is necessary to install the limiting cover 4, the pressing block 10 is aligned with the snap-fit ​​sleeve 7 and the limiting cover 4 is pressed down, so that the pressing block 10 can automatically slide in and snap with the snap-fit ​​sleeve 7, thereby further improving the convenience of the installation process of the limiting cover 4.

[0018] Reference Figure 4As shown in this embodiment: both the front and rear ends of the pressing groove 8 are provided with stop grooves 12, and both the front and rear ends of the pressing block 10 are fixedly connected with stop blocks 13. The inside of the stop groove 12 is slidably connected with the stop block 13. Through the setting of the stop groove 12 and the stop block 13, the pressing block 10 can have a stable limiting effect when it is popped out by the elastic force of the elastic spring 9, so that the pressing block 10 will not pop out excessively, effectively improving the stability of the limiting cover 4 during installation.

[0019] Reference Figure 4 As shown in this embodiment: a rubber contact pad 14 is installed inside the placement groove 5. By setting the rubber contact pad 14, the syringe filter can have greater friction when placed in the placement groove 5, thereby making the placement of the syringe filter more stable and less prone to shaking or displacement, effectively improving the placement effect.

[0020] Reference Figure 4 As shown in this embodiment: multiple elastic sheets 15 are installed on the top of the placement plate 3. The top of the elastic sheet 15 abuts against the bottom of the limiting cover 4. By setting the elastic sheet 15, when it is necessary to remove the limiting cover 4, the limiting cover 4 is released from its fixed position. At this time, the elastic force stored in the elastic sheet 15 is released, causing the limiting cover 4 to pop up a certain distance, thus making the removal of the limiting cover 4 more convenient.

[0021] Reference Figure 2 and Figure 3 As shown in this embodiment: guide grooves 16 are provided at both the front and rear ends of the placement plate 3, and guide posts 17 are fixedly connected to both the front and rear ends of the inner side of the limiting cover 4. The inner side of the guide groove 16 is slidably connected to the guide post 17. Through the setting of the guide groove 16 and the guide post 17, a stable guiding effect can be formed when the limiting cover 4 is installed on the placement plate 3, so that the pressing block 10 can automatically align with the snap-fit ​​sleeve 7, thereby effectively improving the efficiency of installing the limiting cover 4 on the placement plate 3.

[0022] Reference Figure 2 and Figure 3 As shown in this embodiment, the surfaces of the placement plate 3 and the limiting cover 4 are both coated with Teflon coating. By applying Teflon coating to the surfaces of the placement plate 3 and the limiting cover 4, the corrosion resistance and wear resistance of the surfaces of the placement plate 3 and the limiting cover 4 can be effectively enhanced, so that they can still maintain good service condition in humid or chemical environments and extend the service life of the overall structure.

[0023] Working principle: When the operator needs to use the syringe filter, both pressing blocks 10 are pressed inward simultaneously to move them into the pressing groove 8, thus releasing the limiting cover 4 from the placement plate 3. The limiting cover 4 can then be removed from the placement plate 3, and the syringe filter can be taken out for use. After taking it out, the limiting cover 4 is aligned with the placement plate 3 and snapped in, and the pressing blocks 10 are aligned with the snap-fit ​​sleeve 7 and snapped in. After snapping, the elastic force of the spring spring 9 drives the pressing blocks 10 to be firmly snapped in the snap-fit ​​sleeve 7, thereby achieving quick installation of the limiting cover 4 after the syringe filter is taken out; by installing on the surface of the placement plate 3... A removable and fixed limiting cap 4 provides stable positioning for the syringe filter during storage, preventing it from tipping over due to external impacts and effectively improving its stability during placement. The angled design 11 allows for easy installation of the limiting cap 4; simply align the pressing block 10 with the snap-fit ​​sleeve 7 and press the limiting cap 4 downwards to allow the pressing block 10 to slide in and engage with the snap-fit ​​sleeve 7, further enhancing the ease of installation. The stop groove 12 and stop block 13 further facilitate this process. When the pressing block 10 is ejected by the elastic force of the spring spring 9, it has a stable limiting effect, thus preventing the pressing block 10 from ejecting excessively and effectively improving the stability of the limiting cover 4 during installation. The rubber contact pad 14 provides greater friction when the syringe filter is placed in the placement slot 5, making the syringe filter more stable and less prone to shaking or shifting, effectively improving the placement effect. The elastic plate 15 releases the stored elastic force when the limiting cover 4 needs to be removed, causing the limiting cover 4 to move... The upper part pops up a certain distance, making the removal of the limiting cover 4 more convenient. Through the setting of the guide groove 16 and the guide post 17, the limiting cover 4 can form a stable guiding effect when it is installed on the placement plate 3, so that the pressing block 10 can automatically align with the snap sleeve 7, thereby effectively improving the efficiency of the limiting cover 4 being installed on the placement plate 3. By applying a Teflon coating to the surface of the placement plate 3 and the limiting cover 4, the corrosion resistance and wear resistance of the surface of the placement plate 3 and the limiting cover 4 can be effectively enhanced, so that they can still maintain a good working condition in humid or chemical environments, and extend the service life of the overall structure.

[0024] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
