Description

Technical Field

[0001] The utility model relates to the technical field of fluorescence detectors, in particular to a handheld fluorescence quantitative detector. Background Art

[0002] Based on the principle of firefly luminescence, a fluorescence detector uses the "luciferase-luciferin system" to quickly detect adenosine triphosphate (ATP). Since all living cells contain a constant amount of ATP, the ATP content can clearly indicate the amount of microorganisms and other biological residues in a sample, which is used to judge the hygiene status. The fluorescence detector is applicable to the monitoring of key control points in the production process of food and beverages, and the instant sampling monitoring of medical systems and health supervision agencies.

[0003] In order to facilitate the carrying of a fluorescence detector, a handheld fluorescence quantitative detector is needed. For example, the Chinese patent publication number "CN214894862U" in the prior art discloses a handheld portable ATP fluorescence detector, which includes a detector body, a display screen, buttons, a folding back panel, a sliding rod, a sliding block, a deployment spring, a connecting rod, and a clamping mechanism. The display screen and buttons are arranged on the front side of the detector body. A folding groove is opened on the back of the detector body. The folding back panel is rotatably installed in the folding groove. A sliding rod is vertically arranged in the folding groove. A sliding block is slidably installed on the sliding rod. A deployment spring is sleeved outside the top of the sliding rod. The sliding block is connected to the bottom of the folding back panel through a connecting rod. The deployed folding back panel will not easily rotate in the reverse direction under the support of the connecting rod, the sliding block, and the deployment spring, making the folding back panel have higher structural strength. This structure only requires two fingers to press the button to quickly and automatically deploy the folding back panel, increasing the convenience of use. Due to the setting of the clamping mechanism, the structural strength of the folding back panel in the folded state is increased, making it not easily deploy.

[0004] In specific operations, when a similar fluorescence detector is used, if it is placed in a storage bag, it is not convenient for detection. If it is held by hand for a long time, the user needs to specifically hold the detector by hand, which may cause fatigue or inconvenience during long-term use. And in the case of requiring two-handed operation, holding the detector may affect the flexibility of use and operation. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages of the inconvenient carrying of the detector in the prior art, and to propose a handheld fluorescence quantitative detector.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Wherein, a receiving groove is provided at the bottom of the housing, a hanging rope is connected in the receiving groove through a wire winding component, and a closing component is provided at the opening of the receiving groove.

[0009] Furthermore, magnetic components are provided on the end faces of the housing and the flip cover, and a pair of the magnetic components attract each other magnetically. The detection port is used for inserting a reagent rod, and the flip cover can close the detection port and press tightly against the reagent rod.

[0010] Furthermore, the wire winding component includes a wire winding roller rotatably connected in the receiving groove. One end of the wire winding roller is fixedly installed with a clamping seat and extends to the outside of the housing to be fixedly installed with a knob. A plurality of card slots are formed around the clamping seat, and the wire winding roller is connected to the hanging rope.

[0011] Furthermore, a clamping part is rotatably connected to the bottom of the housing. A torsion spring is sleeved around the rotating shaft of the clamping part, and both ends of the torsion spring are fixedly connected to the rotating shaft and the inner wall of the housing. One end of the clamping part is bent downward to form a convex part, and the other end extends upward to form a pressing part, and the convex part is engaged with the card slot.

[0012] Furthermore, the closing component includes a baffle. The baffle is rotatably connected to the receiving groove at one side of the opening through a mounting seat. The baffle is used for closing the receiving groove and is provided with elastic claws on the side.

[0013] Furthermore, a buckle is formed by extending the side of the housing, and the elastic claw is bent and is engaged with the buckle.
