Abstract
Description
Technical Field
[0001] This utility model relates to the field of cell preparation operations, and in particular to a forceps used in centrifuge tubes. Background Technology
[0002] Centrifuge tubes are a common experimental tool used in cell preparation experiments. They are mainly used for centrifuging and separating cell samples. Their design and materials usually take into account the efficiency, durability and safety required for the experiment. Generally speaking, centrifuge tubes are made of transparent polypropylene or polyethylene and other high temperature and corrosion resistant plastic materials, which can withstand the strong centrifugal force of high speed centrifugation. The top of the centrifuge tube is usually equipped with a sealing cap to ensure that the sample will not leak during centrifugation and to avoid cross-contamination.
[0003] Existing centrifuge tubes require manual opening of the caps by operators. However, centrifuge tube caps are typically designed to be quite tight. During large-scale preparation operations, frequent opening of multiple caps can lead to finger joint fatigue and, in severe cases, chronic hand damage. Furthermore, manual opening may pose a risk of cell contamination. Current centrifuge tube forceps do not hinge the middle parts of the first and second handles, making it difficult to rotate and adjust the first and second handles. They also lack a circumferential space, making it difficult to fit the centrifuge tube caps. Additionally, they do not use first and second limiting blocks to restrict movement between the first and second handles. Therefore, a new type of centrifuge tube forceps is needed to meet these needs. Utility Model Content
[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a pair of pliers for centrifuge tubes. By hinged to the middle of the first pliers handle and the middle of the second pliers handle, it facilitates the rotation and adjustment of the first and second pliers handles. By providing an encircling space, it facilitates adaptation to centrifuge tube caps. By providing a first limiting block and a second limiting block, it limits the movement between the first and second pliers handles, preventing them from moving when not in use.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pair of pliers for centrifuge tubes includes a first plier handle and a second plier handle, the middle portion of the first plier handle being hinged to the middle portion of the second plier handle; the front side of both the first plier handle and the front side of both the second plier handle are bent outward to form an enclosing space; the rear side of both the first plier handle and the rear side of both the second plier handle have handles for easy gripping; a first limiting block is provided on the first plier handle, and a second limiting block corresponding to the first limiting block is provided on the second plier handle.
[0007] As a preferred embodiment: one end of the first limiting block is fastened to the side wall of the first clamp handle, one end of the second limiting block is fastened to the side wall of the second clamp handle, and the other end of the first limiting block and the other end of the second limiting block can be detachably engaged.
[0008] As a preferred embodiment: the side wall of the first limiting block is recessed inward and provided with a snap-fit groove, and the side wall of the second limiting block is provided with a snap-fit ball that matches the snap-fit groove.
[0009] As a preferred embodiment: the middle part of the first clamp handle and the middle part of the second clamp handle are both recessed inward to form a movable groove. A through hole is opened through the movable groove, and a connecting post is movably arranged in the through hole. The middle part of the first clamp handle and the middle part of the second clamp handle are hinged through the connecting post.
[0010] As a preferred embodiment: the inner front wall of the first clamp handle and the inner front wall of the second clamp handle are provided with a number of anti-slip grooves, and the front sides of the first clamp handle and the front sides of the second clamp handle are both curved outward to form an enclosing space.
[0011] As a preferred embodiment, the handle is ring-shaped, and an anti-slip pad is embedded in the inner wall of the handle.
[0012] As a preferred embodiment: the inner front wall of the first clamp handle and the inner front wall of the second clamp handle are both provided with a plurality of friction grooves, which are evenly distributed at intervals.
[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, by hinged the middle part of the first clamp handle to the middle part of the second clamp handle, it is convenient to rotate and adjust the first and second clamp handles; by setting an encircling space, it is convenient to fit the centrifuge tube cap; by setting a first limiting block and a second limiting block, when the pliers are not in use, by rotating the first clamp handle, the first limiting block on the first clamp handle is moved closer to the second limiting block on the second clamp handle, so that the first limiting block and the second limiting block correspond to each other, and the connection between the first and second clamp handles is limited, preventing the first and second clamp handles from moving when not in use, making it convenient for operators to store, and further improving the practicality of the pliers.

[0021] This utility model is as follows Figures 1 to 4 As shown, a pair of pliers for use with centrifuge tubes includes a first plier handle 10 and a second plier handle 20, wherein:
[0022] The middle part of the first clamp handle 10 is hinged to the middle part of the second clamp handle 20; the front side of the first clamp handle 10 and the front side of the second clamp handle 20 are both bent outward to form an enclosing space 30; the rear side of the first clamp handle 10 and the rear side of the second clamp handle 20 are both provided with handles 21 for easy gripping; a first limiting block 28 is provided on the first clamp handle 10, and a second limiting block 29 corresponding to the first limiting block 28 is provided on the second clamp handle 20.
[0023] When it is necessary to open the centrifuge tube cap, the operator inserts their fingers into the handle 21. The middle part of the first clamp 10 is hinged to the middle part of the second clamp 20. The distance between the first clamp 10 and the second clamp 20 is adjusted, increasing the front distance between the first clamp 10 and the second clamp 20 to fit the diameter of the centrifuge tube cap. The centrifuge tube cap is then encircled by the encircling space 30. The centrifuge tube cap is then rotated to separate the threads on the cap from the centrifuge tube, thus avoiding the risk of cell contamination due to direct contact between the hand and the cap. This helps the user to better separate the cap and is practical. After using the clamps, the first limiting block 28 and the second limiting block 29 limit the clamps.
[0024] By hinged the middle of the first clamp handle 10 to the middle of the second clamp handle 20, it is easy to rotate and adjust the first clamp handle 10 and the second clamp handle 20. By providing an encircling space 30, it is easy to fit the centrifuge tube cap. By providing a first limiting block 28 and a second limiting block 29, when the pliers are not in use, rotating the first clamp handle 10 will move the first limiting block 28 on the first clamp handle 10 closer to the second limiting block 29 on the second clamp handle 20, so that the first limiting block 28 and the second limiting block 29 correspond to each other, and the connection between the first clamp handle 10 and the second clamp handle 20 is limited, preventing the first clamp handle 10 and the second clamp handle 20 from rotating when not in use, making it easy for operators to store, and further improving the practicality of the pliers.
[0025] One end of the first limiting block 28 is fastened to the side wall of the first clamp handle 10, and one end of the second limiting block 29 is fastened to the side wall of the second clamp handle 20. The other end of the first limiting block 28 and the other end of the second limiting block 29 can be detachably snapped together. The first limiting block 28 and the second limiting block 29 are connected by snapping, which is convenient to operate and highly practical.
[0026] The first limiting block 28 has an inwardly recessed locking groove 281 on its side wall, and the second limiting block 29 has a locking ball 291 that matches the locking groove 281 on its side wall; the locking groove 281 and the locking ball 291 are used to achieve the locking of the first limiting block 28 and the second limiting block 29.
[0027] The middle part of the first clamp 10 and the middle part of the second clamp 20 are both recessed inward to form a movable groove 24. A through hole 25 is provided through the movable groove 24, and a connecting post 26 is movably arranged in the through hole 25. The middle part of the first clamp 10 and the middle part of the second clamp 20 are hinged through the connecting post 26. By using the movable groove 24, positional interference when the first clamp 10 and the second clamp 20 move is avoided, and a movable space is provided.
[0028] The inner front wall of the first clamp 10 and the inner front wall of the second clamp 20 are provided with several anti-slip grooves 27. The front sides of the first clamp 10 and the second clamp 20 are both curved outward to form an enclosing space 30. By using several anti-slip grooves 27 and an enclosing space 30, the clamping accuracy of the centrifuge tube cap is improved, and the position of the centrifuge tube cap is prevented from shifting.
[0029] The handle 21 is ring-shaped, and an anti-slip pad 22 is embedded in the inner wall of the handle 21; the use of the anti-slip pad 22 improves the user experience.
[0030] The inner front wall of the first clamp 10 and the inner front wall of the second clamp 20 are provided with a number of friction grooves 23, which are evenly distributed; the friction force is increased by using a number of friction grooves 23.
[0031] The method of using and the principle of this type of forceps for centrifuge tubes are as follows:
[0032] When it is necessary to open the centrifuge tube cap, the operator inserts their fingers into the handle. The middle of the first handle and the middle of the second handle are hinged. The distance between the first and second handles is adjusted, increasing the distance between their front sides to fit the diameter of the centrifuge tube cap. The centrifuge tube cap is then encircled by the encircling space. The centrifuge tube cap is then rotated to separate the threads on the cap from the centrifuge tube, thus avoiding the risk of cell contamination due to direct contact between the hand and the cap. This helps the user to better separate the cap and is practical. After using the forceps, the forceps are limited by the first and second limiting blocks.
[0033] The key design features of this invention are: by hinged to the middle of the first and second clamp handles, the first and second clamp handles can be easily rotated and adjusted; by providing an encircling space, it can be easily adapted to centrifuge tube caps; by providing a first and second limiting block, when the pliers are not in use, rotating the first clamp handle moves the first limiting block on the first clamp handle closer to the second limiting block on the second clamp handle, so that the first and second limiting blocks correspond and limit the connection between the first and second clamp handles, preventing the first and second clamp handles from moving when not in use, facilitating storage for the operator, and further improving the practicality of the pliers.
[0034] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
