Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically an improved push-pull TIP head box. Background Technology

[0002] Tip boxes are mainly used to store pipette tips, facilitating the management of laboratory instrument accessories and improving work efficiency. Currently, most laboratory-used tip boxes are flip-top type, including 96-well and 100-well sizes. Their structural advantages mainly include the snap-fit ​​design of the lid and body, the elastic design of the tray, the transparent plastic material of the lid, and the sleeve design at the junction. However, its significant drawbacks are that its flip-top design leads to unused tips being exposed to the air for extended periods during application, making them prone to contamination; secondly, it is easy for the experimenter to tip it over during operation, causing the entire box of tips to become contaminated and unusable. These drawbacks directly affect the accuracy of experimental results. To address these issues, we propose an improved push-pull type tip box. Utility Model Content

[0003] The purpose of this invention is to provide an improved push-pull TIP head box to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an improved push-pull TIP head box, including a box frame, a box cover assembly at the top of the box frame, an inner support plate on the inner side of the box frame, a plurality of evenly distributed grooves on the inner support plate, and a limiting assembly at the side end of the box frame, the limiting assembly having two symmetrically distributed sets, the two sets of the limiting assemblies being located at the two ends of the box cover assembly respectively. The box cover assembly includes multiple sets of evenly distributed strip-shaped box covers, the strip-shaped box covers and the grooves correspond to each other, the top of the box frame is provided with a top groove, and the strip-shaped box covers are slidably engaged in the top groove; The limiting component includes multiple sets of evenly distributed limiting longitudinal plates, which correspond to the strip-shaped box cover. A longitudinal sliding frame is provided on the outer side of each set of limiting longitudinal plates, and a longitudinal sliding groove corresponding to the limiting longitudinal plate is opened on the inner side of the longitudinal sliding frame. The limiting longitudinal plate is slidably engaged in the corresponding longitudinal sliding groove. Mounting buckles are integrally formed at both ends of the longitudinal sliding frame. Mounting sleeves corresponding to the mounting buckles are fixedly installed on the outer side of the box frame, and the mounting buckles are movably engaged in the corresponding mounting sleeves. A positioning protrusion is integrally formed on the bottom of the limiting longitudinal plate, and a positioning recess that is interference-fitted with the positioning protrusion is fixedly installed on the outer side of the box frame, and the positioning protrusion is movably engaged in the corresponding positioning recess.

[0005] Preferably, one side of the strip-shaped box cover is integrally formed with a sliding strip, and the other side of the strip-shaped box cover is provided with a sliding groove corresponding to the sliding strip. The sliding strip in the strip-shaped box cover is slidably engaged in the sliding groove in the adjacent strip-shaped box cover.

[0006] Preferably, the connection method between the strip-shaped box cover and the top groove at the end position is the same as the connection method of the adjacent strip-shaped box cover.

[0007] Preferably, the top of each strip-shaped box cover is provided with a finger groove.

[0008] Preferably, the side end of the limiting longitudinal plate is integrally formed with a longitudinal protrusion, the longitudinal protrusion is slidably engaged in the longitudinal groove, and the top end of the limiting longitudinal plate is integrally formed with a positioning block.

[0009] Preferably, the bottom end of the inner support plate is provided with a positioning bottom frame, which is fixedly installed on the inner side of the box frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The tip box is designed with a push-pull structure, with multiple sets of strip-shaped lids and slots corresponding one-to-one. The strip-shaped lids can be easily slid and moved horizontally, allowing the corresponding number of tips to be revealed based on the number of tips taken out. At the same time, other tips remain inside the box frame and are protected by the corresponding sets of strip-shaped lids. This effectively prevents unused tips from being exposed to the air and causing contamination, and also prevents the entire box of tips from being contaminated and discarded during the experimenter's operation.

[0011] 2. The TIP head box, including the cover assembly and the limiting assembly, uses a snap-fit ​​fixing structure, which facilitates the disassembly and assembly of the strip cover, the limiting longitudinal plate, and the longitudinal sliding frame for inspection and replacement.

[0019] 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.

[0020] Example: Figure 1-5 As shown, this utility model provides an improved push-pull TIP head box, including a box frame 1, a box cover assembly 2 on the top of the box frame 1, an inner support plate 3 on the inner side of the box frame 1, and a positioning bottom frame 31 at the bottom of the inner support plate 3. The positioning bottom frame 31 is fixedly installed on the inner side of the box frame 1 to position the inner support plate 3. The inner tray 3 has multiple sets of evenly distributed grooves, and the side end of the box frame 1 is provided with a limiting component 4. The limiting component 4 has two sets symmetrically distributed, and the two sets of limiting components 4 are located at the two ends of the box cover component 2 respectively. The lid assembly 2 includes multiple evenly distributed strip lids 21, with each strip lid 21 corresponding to a groove. A top groove is provided on the top of the box frame 1, and the strip lids 21 slide and engage within the top groove. One side of each strip lid 21 has an integrally formed sliding strip 22, and the other side of each strip lid 21 has a sliding groove 201 corresponding to the sliding strip 22. The sliding strip 22 in each strip lid 21 slides and engages within the sliding groove 201 in adjacent strip lids 21, facilitating relative sliding between adjacent strip lids 21. The connection method between the end strip lids 21 and the top groove is the same as the connection method between adjacent strip lids 21. Each top of each strip lid 21 has a finger groove 202, facilitating sliding of the strip lid 21 by placing a finger in the finger groove 202.

[0021] The limiting component 4 includes multiple sets of evenly distributed limiting longitudinal plates 41, which correspond to the strip-shaped box covers 21. The top of the limiting longitudinal plate 41 contacts the end of the corresponding strip-shaped box cover 21, thereby limiting the multiple strip-shaped box covers 21 through the multiple limiting longitudinal plates 41 to prevent the strip-shaped box covers 21 from sliding. The outer side of the multiple sets of limiting longitudinal plates 41 is provided with a longitudinal sliding frame 42, and the inner side of the longitudinal sliding frame 42 is provided with a longitudinal sliding groove 421 corresponding to the limiting longitudinal plate 41. The limiting longitudinal plate 41 is slidably engaged in the corresponding longitudinal sliding groove 421. The side end of the limiting longitudinal plate 41 is integrally formed with a longitudinal protrusion 411, which is slidably engaged in the longitudinal sliding groove 421 to facilitate the vertical sliding of the limiting longitudinal plate 41. The top of the limiting longitudinal plate 41 is integrally formed with a positioning top block 412, which limits the downward movement distance of the limiting longitudinal plate 41 by setting the positioning top block 412. Both ends of the longitudinal sliding frame 42 are integrally formed with mounting buckles 422. The outer side of the box frame 1 is fixedly installed with mounting buckles 423 corresponding to the mounting buckles 422. The mounting buckles 422 are movably engaged in the corresponding mounting buckles 423 to fix the longitudinal sliding frame 42. The bottom of the limiting longitudinal plate 41 is integrally formed with a positioning protrusion 43. The outer side of the box frame 1 is fixedly installed with a positioning recess 431 that is interference-fitted with the positioning protrusion 43. The positioning protrusion 43 is movably engaged in the corresponding positioning recess 431 to position the limiting longitudinal plate 41.

[0022] Working principle: When placing the TIP head, manually move down multiple sets of limiting plates 41 in the two side limiting components 4. At this time, the ends of multiple sets of strip box covers 21 lose their limiting. Place your finger in the finger groove 202 and slide all the strip box covers 21. The strip box covers 21 move horizontally and the top groove opens. Then, multiple TIP heads can be placed in multiple sets of grooves on the inner support plate 3. Then, move multiple strip box covers 21 in the opposite direction and the top groove closes. When it is necessary to remove the tip heads later, one or more sets of strip box covers 21 can be slid to expose the corresponding number of tip heads, depending on the number to be removed. At the same time, the other tip heads remain in the box frame 1 and are protected by the corresponding sets of strip box covers 21. This can effectively prevent unused tip heads from being exposed to the air and causing contamination, and can also prevent the experimenter from tipping over during operation and causing the entire box of tip heads to be contaminated and scrapped.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
