Description

Technical Field

[0001] This utility model relates to the field of testing auxiliary instruments, and in particular to a multifunctional test tube rack. Background Technology

[0002] In the daily operations of chemical analysis and biomedical testing, test tube racks are an essential basic auxiliary tool. They are mainly used for vertical placement, static observation, or temporary storage of test tubes containing various reagents and samples. Traditional test tube racks are made of rigid materials, and their main structure generally includes a base, supporting columns, and fixed shelves with several arrayed holes, which are designed to provide basic support points for test tubes.

[0003] However, existing test tube racks have revealed significant defects in structural adaptability during practical applications. Due to the diversity of experimental projects, researchers often need to use test tubes of different diameters and lengths. Currently, the placement aperture size and shelf support height of most test tube racks on the market are fixed at the factory, and cannot be flexibly adjusted according to the actual specifications of the test tubes. This leads to the following problems when dealing with test tubes of different diameters: if the aperture is too large, thin test tubes will tilt or sway within the rack, and may even collide and break during movement; if the aperture is too small, thick test tubes cannot be placed. At the same time, for test tubes of different lengths, the fixed-height shelves cannot provide proper support. Long test tubes are prone to instability due to their high center of gravity, while short test tubes may sink deep into the rack and be difficult to retrieve. This single structure, which cannot accommodate multiple specifications of test tubes at the same time, forces laboratories to purchase multiple different models of test tube racks for unforeseen needs. This not only increases the procurement cost of experimental equipment but also greatly occupies valuable laboratory workspace, causing many inconveniences for researchers.

[0004] Therefore, this utility model proposes a multifunctional test tube rack to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing test tube racks, where the aperture and shelf height are fixed, making it impossible to simultaneously accommodate test tubes of different diameters and heights, resulting in unstable placement and poor applicability, this utility model aims to provide a multifunctional test tube rack with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a multifunctional test tube rack, including: a test tube rack body, fixed columns fixedly connected to the left and right sides inside the test tube rack body, multiple adjustment slots opened between the test tube rack body and the fixed columns, a card plate slidably connected inside the adjustment slots, and a fixed plate adjustablely disposed inside the test tube rack body. It also includes multiple locking posts fixedly connected between adjacent plates, multiple round holes opened on the left and right sides of the test tube rack body, multiple support grooves opened on the left and right sides of the fixing plate, multiple placement holes opened on the top of the fixing plate, multiple springs fixedly connected inside the placement holes, and clamps fixedly connected between adjacent springs. The outer wall of the locking post can engage with the inside of the circular hole; the support groove engages with the locking plate to support and limit the fixing plate when the locking plate is inserted into the adjustment groove; and the spring and clamp are used to adaptively clamp the test tube inserted into the placement hole.

[0007] Preferably, pull rings are fixedly connected to the side of the multiple clamping plates away from the fixed post. When the pull rings are pulled manually, they can drive the clamping plates to slide along the adjustment groove and cause the clamping post to disengage from the round hole, thereby releasing the position lock of the clamping plates and realizing the up and down adjustment of the fixed plate.

[0008] Preferably, a rubber ring is fixedly connected to the outer wall of the locking post. The rubber ring increases the friction between the locking post and the inner wall of the circular hole, thereby preventing the locking plate from loosening and improving the stability of the locking structure.

[0009] Preferably, the spring is used to provide elastic force. When a test tube with a larger diameter is inserted into the placement hole, the outer wall of the test tube presses against the corresponding clamping plate. The clamping plate will drive the connected spring to contract, generating a reverse clamping force.

[0010] Preferably, as a supplement to the above scheme, when a test tube with a smaller diameter is inserted into the placement hole, the spring releases its elastic potential energy and actively pushes the corresponding clamping plate to move towards the test tube until the clamping plate is tightly attached to the outer wall of the test tube, thereby achieving reliable fixation.

[0011] Preferably, a label rack is fixedly connected to the front right side of the test tube rack body. The label rack has an internal space for accommodating labels, and the structure facilitates the classification management and rapid identification of test tubes.

[0012] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art where the test tube rack has a fixed hole diameter, which cannot accommodate test tubes of different diameters and causes shaking or instability. It achieves the effect of being able to adaptively clamp test tubes of different diameters, with a firm and reliable fixation and strong applicability.

[0013] 2. This utility model solves the problem in the prior art where the height of the test tube rack is fixed and cannot accommodate test tubes of different heights, resulting in wasted space or inconvenience in retrieval, by setting a fixed plate that can be adjusted up and down and designing a sliding and locking structure between the pull ring, the locking plate, the locking post, the adjustment groove, the round hole and the support groove. The fixed plate height can be easily adjusted and the structure is stable after adjustment through the support of the locking plate and the locking post, thus meeting the needs of placing test tubes of different sizes.

[0014] 3. This utility model solves the problem of the lack of a dedicated marking area in the existing test tube rack, which is not conducive to the classification and rapid identification of test tubes, by fixing a labeling rack to the front end of the test tube rack body. It achieves the effect of making it easier for operators to place information labels, realizing clear classification and rapid retrieval of test tubes, and improving the efficiency of experimental management.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] Example: Please refer to Figures 1 to 4 This utility model provides a multifunctional test tube rack, which aims to solve the problems in the prior art where test tube racks cannot simultaneously accommodate test tubes of different diameters and heights due to fixed aperture and layer height, resulting in unstable placement or inapplicability, and lack of convenient classification and labeling functions.

[0019] like Figure 1 and Figure 2 As shown, the device includes a test tube rack body 1 and fixed posts 2 fixedly connected to the left and right sides inside the test tube rack body 1. The test tube rack body 1 serves as an overall support frame, with circular holes 6 formed by multiple circular through holes on its left and right side walls. Multiple adjustment grooves 3 are provided between the test tube rack body 1 and the fixed posts 2, serving as vertical guide channels. A locking plate 4 is slidably connected inside the adjustment groove 3, and the locking plate 4 slides back and forth vertically within the adjustment groove 3. Multiple locking posts 5 are fixedly connected between adjacent locking plates 4, with the positions of the locking posts 5 corresponding to the positions of the circular holes 6 on the side walls of the test tube rack body 1. The outer wall of the locking post 5 can be engaged and limited inside the circular holes 6. A fixed plate 8 for supporting test tubes is adjustablely provided inside the test tube rack body 1. The left side of the fixed plate 8... Support grooves 9 are provided on both right sides. The shape of the support grooves 9 is adapted to the clamping plate 4. When the clamping plate 4 is inserted into the adjustment groove 3, it can be simultaneously inserted into the support groove 9, thereby supporting and limiting the fixing plate 8. The top of the fixing plate 8 has multiple placement holes 10 that penetrate the plate body. The placement holes 10 serve as channels for inserting test tubes. Multiple springs 11 are fixedly connected inside. Clamping plates 12 are fixedly connected between adjacent springs 11. The elastic deformation of the springs 11 drives the clamping plates 12 to move, thereby adaptively clamping test tubes of different diameters. In addition, a labeling rack 13 is fixedly connected to the front right side of the test tube rack body 1. The labeling rack 13 has a space inside to accommodate labels, so that the experimenter can quickly identify the purpose of different test tubes or the information of the internal samples.

[0020] Please refer to Figure 1 , Figure 2 and Figure 4 A height-adjustable locking structure mainly consists of a locking plate 4, a locking post 5, and a pull ring 7, such as... Figure 4 As shown, the card plate 4 is in the shape of a flat insert. Multiple card plates 4 are fixedly connected to each other by card posts 5. A rubber ring is fixedly connected to the outer wall of the card post 5. Pull rings 7 are fixedly connected to the side of multiple card plates 4 away from the fixed post 2.

[0021] In the assembled state, the height adjustment locking structure forms the following cooperative relationship with the test tube rack body 1 and the fixing plate 8: the adjustment groove 3 formed between the test tube rack body 1 and the fixing column 2 is used to accommodate the card plate 4 and provide vertical sliding guidance; the round holes 6 opened on the left and right sides of the test tube rack body 1 are positioned corresponding to the adjustment groove 3 in the horizontal direction and are used to receive the insertion and engagement of the card column 5; the support grooves 9 opened on the left and right sides of the fixing plate 8 have a cross-sectional shape that matches the insertion end of the card plate 4 and are used to achieve engagement when the card plate 4 is inserted.

[0022] This structural design ensures the height adjustment and stable locking of the fixing plate 8: When the height of the fixing plate 8 needs to be adjusted, the operator pulls the pull ring 7, causing the locking plate 4 to slide outward along the adjustment groove 3. The sliding of the locking plate 4 simultaneously causes the fixedly connected locking post 5 to disengage from the round hole 6, and also causes the locking plate 4 to disengage from the support groove 9 of the fixing plate 8. At this time, the locking of the locking plate 4 is released, allowing the fixing plate 8 to move up and down along the vertical direction of the fixing post 2. After adjustment, the locking plate 4 is pushed back into the adjustment groove 3 of the corresponding height. During the pushing process, the insertion end of the locking plate 4 is simultaneously inserted into the support groove 9 of the fixing plate 8, forming a stable support limit for the fixing plate 8. At the same time, the locking post 5 is also simultaneously inserted into the corresponding round hole 6. Through the engagement of the locking post 5 and the round hole 6 and the friction of the rubber ring, the locking plate 4 is stably locked, thereby ensuring the stability of the position of the fixing plate 8.

[0023] As a preferred embodiment, in order to achieve adaptive clamping of test tubes of different diameters, please refer to the following: Figure 3 Multiple springs 11 are fixedly connected inside the placement hole 10 of the fixing plate 8. Clamping plates 12 are fixedly connected between adjacent springs 11. The springs 11 are preferably compression springs 11. The structure utilizes the springs 11 to provide elastic force. When a test tube with a larger diameter is inserted into the placement hole 10, the outer wall of the test tube squeezes the corresponding clamping plate 12, and the clamping plate 12 drives the connected springs 11 to contract. When a test tube with a smaller diameter is inserted into the placement hole 10, the springs 11 release elastic potential energy and push the corresponding clamping plate 12 to move towards the test tube, so that the clamping plate 12 fits tightly against the outer wall of the test tube.

[0024] As another preferred implementation method, to achieve the classification management and rapid identification of test tubes, please refer to... Figure 1 A label rack 13 is fixedly connected to the front right side of the test tube rack body 1. The label rack 13 has a space inside for accommodating labels.

[0025] Working principle: When a test tube needs to be placed, the test tube is inserted into the placement hole 10 at the top of the fixing plate 8. The outer wall of the test tube contacts the multiple clamps 12 inside the placement hole 10. If the diameter of the test tube is large, the outer wall of the test tube presses against the corresponding clamp 12. The clamp 12 drives the connected spring 11 to contract. The spring 11 generates a reverse elastic force, which is transmitted to the outer wall of the test tube through the clamp 12 to form a clamp and fixation. If the diameter of the test tube is small, the spring 11 releases elastic potential energy and pushes the corresponding clamp 12 to move towards the test tube, so that the clamp 12 fits tightly against the outer wall of the test tube, thus achieving stable fixation of the test tube. This adapts to and is compatible with test tubes of different diameters. When adjustment is needed based on the test tube height, the operator pulls the pull ring 7 outwards. The pull ring 7 causes the locking plate 4 to slide outwards along the adjustment groove 3. Simultaneously, the sliding of the locking plate 4 causes the adjacent fixed connecting posts 5 to disengage from the round holes 6 on the left and right sides of the test tube rack body 1, and also causes the locking plate 4 to disengage from the support grooves 9 on the left and right sides of the fixing plate 8. At this time, the locking plate 4 and the fixing plate 8 are released. The operator can then adjust the fixing plate 8 up and down along the vertical direction of the fixing post 2 until it is adjusted to a position that matches the test tube height. After adjustment, multiple locking plates 4 are... Reinsert the plate 4 into the corresponding height adjustment slot 3. During the insertion process, the plate 4 is simultaneously inserted into the support slots 9 on the left and right sides of the two fixed plates 8. Through the engagement of the plate 4 and the support slots 9, the fixed plates 8 are supported and limited to prevent them from moving up and down. During the insertion of the plate 4, multiple pins 5 are simultaneously inserted into the corresponding round holes 6. The rubber ring on the outer wall of the pin 5 increases the friction with the inner wall of the round hole 6, so that the pin 5 and the round hole 6 are tightly engaged, preventing the plate 4 from loosening and ensuring the stability of the fixed plate 8, thus completing the test tube height adaptation adjustment. When it is necessary to classify and manage test tubes, the operator can place the label with the test tube information into the space inside the label rack 13 fixedly connected to the front right side of the test tube rack body 1. This is used to quickly distinguish the purpose or internal sample information of different test tubes, so as to realize the classification and management and rapid identification of test tubes.
