Description

Technical Field

[0001] This utility model relates to the field of cell culture, and in particular to a cell scraper storage rack with a boss-limited design. Background Technology

[0002] In cell culture experiments, cell scrapers are a commonly used tool for scraping cells from culture flasks or dishes.

[0003] However, current cell scraper storage devices have several shortcomings. Firstly, traditional storage methods often involve simple boxes, which can cause scrapers to collide and rub against each other, damaging the blades and affecting subsequent cell scraping. This can also lead to scraper contamination, compromising experimental accuracy and safety. Secondly, existing storage devices lack effective restraint and fixation structures for the scrapers. During handling and storage, scrapers are prone to shifting and tipping, making it difficult to quickly locate the required scraper and reducing experimental efficiency. Furthermore, when disassembling the scraper (i.e., separating the handle from the blade), there is a lack of specialized auxiliary structures. Operators often need to manually separate them, which is inconvenient and can damage the scraper or injure their hands due to improper force. These devices fail to meet the demands for convenience, safety, and efficiency in cell culture experiments. Therefore, a cell scraper storage rack with a raised restraint mechanism is proposed to address these issues. Utility Model Content

[0024] 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.

[0025] Reference Figure 1 , Figure 2 , Figure 3This utility model provides an embodiment of a cell scraper storage rack with a boss-limited design, comprising a base 1. The top of the base 1 is provided with several sets of quick-assembly components, each including a support block 3. The support block 3 is fixedly connected to the top of the base 1. A groove 31 is formed on the top of the support block 3. Sliding blocks 32 are slidably connected to both sides of the inner wall of the groove 31. A blade placement block 33 is fixedly connected to the top of one sliding block 32, and a handle fixing block 34 is fixedly connected to the top of the other sliding block 32. A blade placement groove 330 is formed on the side of the blade placement block 33 corresponding to the handle fixing block 34, and a cell scraper 331 is placed in the blade placement groove 330. A handle fixing block 34 is formed on the side of the blade placement block 33. The blade has a handle fixing groove 341 for fixing the handle connection part. The handle fixing block 34 is fixedly connected to the abutment block 342 on both sides of the handle fixing groove 341 for abutting the cell scraper 331. The blade placement block 33 has a notch 332 at the position corresponding to the connection hole on the cell scraper 331 in the blade placement groove 330. When installing the cell scraper 331, the handle connection part is inserted into the handle fixing groove 341 of the handle fixing block 34, and the handle fixing block 34 and the blade placement block 33 are brought close and fitted together so that the elastic buckle of the handle connection part in the handle fixing groove 341 is inserted into the connection hole on the cell scraper 331, thus completing the installation of the cell scraper 331. At this time, the handle can be pulled out through the opening of the notch 332.

[0026] Reference Figure 3 , Figure 4 Limiting grooves 333 are provided on both sides of the blade placement block 33. The inner walls of the two limiting grooves 333 are slidably connected to retaining strips 334. One side of the retaining strips 334 can extend into the blade placement groove 330. A second spring 336 is fixedly connected between the retaining strips 334 and the inner wall of the blade placement block 33. Under normal conditions, the tension of the second spring 336 will cause the end of the retaining strips 334 near the retaining strips 334 to be stored in the limiting grooves 333. A pusher 335 is fixedly connected to the side of the retaining strips 334 on the outer wall of the blade placement block 33. When it is necessary to peel the blade off the handle, align the handle with the notch 332 and put the cell scraper 331 into the blade placement groove 330. By pressing the pushers 335 on both sides, the retaining strips 334 slide into the blade placement groove 330 and lock the cell scraper 331 in the blade placement groove 330. At this time, by applying a direction that separates from the cell scraper 331 to the handle, the elastic buckle embedded in the connection hole on the cell scraper 331 on the handle can be pulled out.

[0027] Reference Figure 2A first spring 35 is fixedly connected between the two sliders 32. A gear 36 is rotatably connected inside the support block 3 below the sliders 32. Two racks 37 are meshed on both sides of the gear 36, and the two racks 37 pass through the corresponding side of the support block 3 and are fixedly connected to the corresponding sliders 32. A push block 38 is fixedly connected to one end of the two racks 37 outside the support block 3. By pressing the push blocks 38 on both sides of the support block 3, the sliders 32 connected to the two racks 37 are brought closer together, thereby causing the blade placement block 33 to move closer together to the corresponding handle fixing block 34.

[0028] Reference Figure 1 A cover plate 2 is hinged to the base 1 and is designed to flip up. An elastic retaining ring 21 is fixedly connected to the inner wall of the cover plate 2 to fix the knife handle. A magnetic block 22 is fixedly connected to the cover plate 2 to magnetically attract and fix the base 1 when the cover plate 2 is closed.

[0029] Working principle: When installing the cell scraper 331, first insert the connecting part of the handle into the handle fixing groove 341 of the handle fixing block 34, while ensuring that the blade part of the cell scraper 331 is located in the blade placement groove 330 of the blade placement block 33. Then press the push blocks 38 on both sides of the support block 3. The push blocks 38 drive the racks 37 fixedly connected to them to move. Since the two racks 37 mesh with the two sides of the gear 36 respectively, the rotation of the gear 36 will cause the two racks 37 to drive the corresponding sliders 32 to move closer to each other in the sliding groove 31, thereby bringing the blade placement block 33 and the handle fixing block 34 on the top of the slider 32 closer together. The elastic buckle of the handle connecting part is inserted into the connecting hole on the cell scraper 331, completing the installation of the cell scraper 331. Then, the handle can be pulled out through the opening of the notch 332 for use.

[0030] When it is necessary to disassemble the cell scraper 331, that is, to separate the handle from the blade, align the handle with the notch 332, place the blade part of the cell scraper 331 into the blade placement groove 330, and then press the push strips 335 on both sides of the blade placement block 33. The push strips 335 drive the locking strip 334 to slide in the limiting groove 333 and compress the second spring 336, so that one end of the locking strip 334 extends into the blade placement groove 330 and locks the cell scraper 331. At this time, apply a force to the handle in the direction of separation from the cell scraper 331, and the elastic buckle embedded in the cell scraper 331 connection hole on the handle can be pulled out, realizing the separation of the handle from the blade. After disassembly, release the push strip 335, the second spring 336 returns to its deformation, and drives the locking strip 334 back into the limiting groove 333.

[0031] When storing the cell scraper 331, place the assembled or disassembled cell scraper 331 in the quick assembly, cover it with the cover plate 2, and the elastic retaining ring 21 on the inner wall of the cover plate 2 will fix the handle. The magnetic block 22 on the cover plate 2 is magnetically attracted to the base 1, so that the cover plate 2 is stably closed, and the storage of the cell scraper 331 is completed.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
