[0002] In the field of molecular biology, polymerase chain reaction (PCR) is a commonly used experimental technique.

[0003] The existing PCR detector is large in size, has an overall square structure, and is relatively heavy. It is inconvenient for technicians to carry and move it when changing locations for multi-channel fluorescence detection. Each time the PCR detector is moved, it is necessary to hold up the bottom ends of both sides of the PCR detector with both hands before it can be moved. Based on the problem of inconvenience in movement, the applicant proposed a convenient handle for the real-time fluorescence PCR detector according to actual experimental needs. Utility Model Content

[0004] The purpose of the utility model is to provide a convenient handle for a real-time fluorescence PCR detector to solve the problems encountered in the above-mentioned background technology.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A convenient handle for a real-time fluorescence PCR detector comprises a PCR detector body, support frames are provided on both sides of the PCR detector body, extension parts are provided on both sides of the top back of the support frame, the extension parts are inclined upward and protrude outward, and a pull rod is fixed between the two extension parts.

[0007] In the above scheme, a reaction chamber is provided on the inner side of the top of the PCR detector body, and a bracket is provided on the front bottom of the PCR detector body.

[0008] In the above scheme, the support frame includes a side plate shell and an inner frame body, and the side plate shell is detachably connected to the inner frame body. A rib plate is provided inside the extension part, and the rib plate is a fence-like structure in the inner frame body. A positioning column and a hole groove are provided on the extension part, and the side plate shell is positioned and installed with the inner frame body through the positioning column, and the pull rod is fixed with the inner frame body through the cooperation of screws and hole grooves.

[0009] In the above solution, the pull rod is a long rod-shaped structure, a through-weight reduction hole is provided inside the pull rod, and a threaded hole is provided on the end surface of the pull rod to match the inner side of the extension portion. The cross section of the pull rod is a shuttle-shaped structure, a first flange is provided at one end, and a second flange is provided at the other end, and the arc length of the curved surface of the first flange is greater than the arc length of the curved surface of the second flange.

[0010] As a preferred solution, two weight-reducing holes and two threaded holes are provided respectively; the two weight-reducing holes are long groove-shaped structures and are symmetrically arranged; the two threaded holes are located at the top and bottom positions between the two weight-reducing holes.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: extensions are provided on both sides of the top of the back of the support frame, the extensions are inclined upward and protrude outward, and a pull rod is fixed between the two extensions. The PCR detector can be lifted by the pull rod with only one hand, and it is convenient to move and carry after being lifted.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is now further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the relevant components of the utility model.

[0018] According to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0019] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment 1, as Figure 1 As shown, a convenient handle of a real-time fluorescence PCR detector includes a PCR detector body 1. Support frames 2 are provided on both sides of the PCR detector body 1. The support frame 2 provides a necessary structure for the PCR detector. The functional modules provided inside the support frame can perform fluorescence detection on the target nucleic acid (DNA / RNA). The overall volume is small, which greatly reduces the space occupied by existing products and makes it easy to carry.

[0021] Extensions 21 are provided on both sides of the top of the back of the support frame 2. The extensions 21 are tilted upward and protrude outward, and a pull rod 3 is fixed between the two extensions 21. The pull rod 3 only requires one hand to lift the PCR detector, and it is convenient to move and carry after lifting. Because the extension 21 is tilted upward and protrudes outward, when doing experiments, the pipette 4 can be hung on the pull rod 3 through its own hook 41, which can reduce the laboratory's additional purchase of a bracket for placing the pipette 4. In addition, the design of the handle 3 facilitates the hanging of the pipette 4, which is convenient for extraction, use and storage, and solves the problem that it is inconvenient to carry the pipette 4 when using it conveniently, and the pipette 4 can only be placed anywhere.

[0022] As a preferred solution, a reaction chamber 11 is provided on the inner side of the top of the PCR detector body 1. The prepared reagent sample is dripped into the PCR reaction cup using a pipette gun 4 and placed in the reaction chamber 11 for fluorescence detection. A bracket 12 is provided at the bottom of the front of the PCR detector body 1. When moving the PCR detector, one hand can be used to carry the pull rod 3, and the other hand can be held in the bracket 12, further improving the stability of moving the PCR detector.

[0023] Example 2, based on the solution of Example 1, please refer to Figure 1 and Figure 2The support frame 2 includes a side plate shell 22 and an inner frame body 23, and the side plate shell 22 is detachably connected to the inner frame body 23. In implementation, a snap connection can be used. This type of connection method is a common method for installing hard plastic shells at present. It is mainly to press the hook into the slot in the product to snap together, which plays a role of snap connection and fixing. It can also be fixed together by splicing male and female grooves and fixing them with screws.

[0024] In order to improve the stability of the PCR detector and reduce consumables, the interior of the extension part 21 is designed to be hollow, and a rib plate 24 is provided inside the extension part 21. The rib plate 24 is in a fence-like structure in the inner frame 23, thereby covering the interior of the extension part 21 and playing a role of fixed support.

[0025] Furthermore, the extension portion 21 is provided with a positioning column 25 and a hole slot 26, which can be arranged on the rib plate 24 to improve the stability after the screw 27 is installed. The side plate shell 22 is positioned and installed with the inner frame 23 through the positioning column 25, and the inner frame 23 is fixed with the pull rod 3 through the cooperation of the screw 27 and the hole slot 26.

[0026] Example 3, based on the scheme of Example 1 or 2, please refer to Figure 3 The pull rod 3 is a long rod-shaped structure, and a through-weight-reducing hole 33 is provided inside the pull rod 3. The end surface of the pull rod 3 is provided with a threaded hole 34 that matches the inner side of the extension part 21. During installation, after the screw 27 is screwed into the hole groove 26, it is further screwed into the threaded hole 34 on the end surface of the pull rod 3 to fix the pull rod 3 between the two extension parts 21.

[0027] As a preferred solution, the cross section of the pull rod 3 is a shuttle-shaped structure, with a first flange 31 at one end and a second flange 32 at the other end, and the arc length of the curved surface of the first flange 31 is greater than the arc length of the curved surface of the second flange 32. The curved surface arc length of the first flange 31 is longer, which can be convenient for the experimenter to hold and carry, while the curved surface arc length of the second flange 32 is shorter, which can facilitate the pipette gun 4 to be hung on it.

[0028] During implementation, two weight-reducing holes 33 and two threaded holes 34 can be provided respectively. The two weight-reducing holes 33 are long slot-shaped structures and are symmetrically arranged. According to the shuttle-shaped pull rod 3, the weight of the PCR detector can be reduced as much as possible. The two threaded holes 34 are located at the top and bottom positions between the two weight-reducing holes 33, and the top and bottom positions of the pull rod 3 are fixed respectively. When fixing, the screws 27 can be selected as M3*6 stainless steel screws.
