Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a door-flipping mechanism for a nucleic acid detection analyzer. Background Technology

[0002] Currently, fully automated nucleic acid testing analyzers use reagent kits, which are primarily accessed and removed from the instrument's compartment via a hinged door. The smoother the opening and closing of this door, the more convenient the instrument is to use and the better the user experience. Existing mechanisms mainly control the opening and closing of the door using the outward force of a torsion spring combined with the opening and closing of an electromagnet. Because the reagent kits cannot move inside the compartment, there is often an internal limiter for upward movement of the kits within the instrument. Due to variations in kit batch size, the kits may rub against this internal limiter during ejection, causing jamming. Furthermore, the hinged door surface is flush with the outer casing and cannot be opened manually, which may prevent the kits from exiting the compartment. Utility Model Content

[0003] The purpose of this invention is to provide a door-flipping mechanism for a nucleic acid detection analyzer to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A door-opening mechanism for a nucleic acid testing analyzer includes a frame. The frame is equipped with a door-opening body, a sliding tray, a clamping component, and an unlocking component. The door-opening body is rotatably connected to the frame and covers the inlet of the chamber. The sliding tray is slidably connected to the chamber and is connected to the door-opening body. The door-opening body drives the sliding tray to slide on the chamber. The clamping component is used to lock the door-opening body so that the door-opening body cannot be opened. The unlocking component is used to move the clamping component so that the clamping component does not lock the door-opening body. When the flip door is closed, the sliding tray is located inside the compartment; when the flip door is open, the sliding tray extends out of the compartment.

[0005] Furthermore, the clamping assembly includes a clamping member and an elastic member. The clamping member is slidably mounted on the frame to lock the flip door body, and the elastic member is used to press the clamping member toward the flip door body.

[0006] Furthermore, one of the flip door body and the clamping component is provided with a slot, and the other is provided with a block. When the flip door body is in the closed state, the block engages with the slot.

[0007] Furthermore, the left and right sides of the flip door body are provided with flip door side plates, and at least one flip door side plate is provided with an arc edge facing the frame. The slot is provided on the arc edge, and the block is provided on the clamping member. During the opening process of the flip door body, the block slides and engages with the arc edge.

[0008] Furthermore, the elastic element is a spring.

[0009] Furthermore, the unlocking component includes a lifting member and a lifting driver that drives the lifting member to move up and down. The lifting member drives the pressing member to move toward the side opposite to the flip door body, so that the pressing member does not lock the flip door body.

[0010] Furthermore, the hinged door body is rotatably connected to the compartment body via a pivot, and a torsion spring is provided on the pivot to help the hinged door body return to its original position.

[0011] Furthermore, a linkage component is provided on the flip door body, and the flip door body drives the sliding tray to slide outward through the linkage component during the opening process.

[0012] Furthermore, the sliding tray includes a tray body and a hook-shaped structure disposed on the tray body. The linkage is located inside the hook-shaped structure and is used to push the hook-shaped structure outward, thereby causing the entire sliding tray to slide outward.

[0013] Furthermore, the clamping component locks the flip door body from top to bottom, and the unlocking component moves the clamping component from bottom to top, so that the clamping component does not lock the flip door body.

[0014] Compared with the prior art, the advantages of this utility model are: the utility model has a reasonable design and simple structure. It prevents the reagent kit from getting stuck in the instrument by moving the sliding tray through the flip door body. Moreover, the opening and closing of the flip door body is controlled by the pressing component and the unlocking component, making it easy to operate. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-4 A flip-door mechanism for a nucleic acid testing analyzer includes a frame 1, on which a flip-door body 2, a sliding tray 3, a clamping component, and an unlocking component 4 are mounted. The flip-door body 2 is rotatably connected to the frame 1 and covers the inlet of a compartment 7. The sliding tray 3 is used to hold reagent kits and is slidably connected to the compartment 7. The flip-door body 2 drives the sliding tray 3 to slide on the compartment 7. The clamping component locks the flip-door body 2, preventing it from opening. The unlocking component 4 moves the clamping component, releasing the clamping component from locking the flip-door body 2. When the flip-door body 2 is closed, the sliding tray 3 is located inside the compartment 7. When the flip-door body 2 is open, the sliding tray 3 extends out of the compartment 7.

[0022] Continue reading Figure 1 and Figure 2 In one embodiment of this utility model, the clamping assembly includes a clamping member 5 and an elastic member 6. The clamping member 5 is a vertically arranged clamping bar, which is slidably mounted on the frame 1 to lock the flip door body 2. The elastic member 6 is used to press the clamping member 5 toward the flip door body 2. The upper end of the clamping member 5 is slidably inserted into the top of the frame 1. The elastic member 6 is preferably a spring sleeved on the upper end of the clamping member 5, with the upper end of the spring abutting against the top plate of the frame 1 and the lower end abutting against the main body of the clamping member 5. The clamping assembly locks the flip door body 2 from top to bottom.

[0023] Specifically, the lifting actuator is preferably an electric nut screw pair, which includes a motor, screw, nut block, guide rod, etc., and the lifting component 400 is fixedly connected to the nut block. The structure of the electric nut screw pair is well-known technology and will not be described in detail. In addition, the lifting actuator can also be a cylinder, hydraulic cylinder, etc.

[0024] Continue reading Figures 1-3 In one embodiment of this utility model, one of the flip door body 2 and the clamping member 5 is provided with a slot 202, and the other is provided with a block 500. When the flip door body 2 is in the closed state, the block 500 is engaged with the slot 202.

[0025] Specifically, the left and right sides of the flip door body 2 are provided with flip door side plates 200. One of the flip door side plates 200 is provided with an arc edge 201 facing the frame 1. The slot 202 is provided on the arc edge 201, which is equivalent to the notch of the arc edge 201. The locking block 500 is a round rod structure and is provided at the lower end of the clamping member 5. During the opening process of the flip door body 2, the locking block 500 and the arc edge 201 slide together.

[0026] Continue reading Figures 1-3 In one embodiment of this utility model, the hinged door body 2 is rotatably connected to the compartment body 7 via a pivot 203. A torsion spring 204 is provided on the pivot 203, which helps the hinged door body 2 to open. A linkage 205 is provided on the inner side of the hinged door side panel 200. The linkage 205 is a protrusion. The sliding tray 3 includes a horizontal tray body 300 and a hook-shaped structure 301 located on the lower outer side of the tray body 300. The linkage 205 is located inside the hook-shaped structure 301. During the opening process of the hinged door body 2, the linkage 205 pushes the hook-shaped structure 301 outward, causing the entire sliding tray 3 to slide outward.

[0027] Continue reading Figure 1 , Figure 2 and Figure 4 In one embodiment of this utility model, the upper end of the unlocking component 4 frame 1 includes a lifting member 400 and a lifting driver for driving the lifting member to move up and down. The lifting member 400 drives the pressing member 5 to move toward the side opposite to the flip door body 2, so that the pressing member 5 does not lock the flip door body 2. The unlocking component 4 drives the pressing member 5 to move from bottom to top, so that the pressing component does not lock the flip door body 2.

[0028] The principle of this invention is as follows: When the lifting member 400 rises to a certain position, it contacts the pressing member 5, causing the pressing member 5 to move upward. When the lifting member 400 descends, the pressing member 5 moves downward to a certain position under the influence of the spring force. When the flip door body 2 is open, the locking block 500 installed under the pressing member 5 presses against the arc edge 201 of the flip door body 2, maintaining a generally small force. Under the influence of the torsion spring 204, the flip door body 2 tends to open outward. The sliding tray 3 moves back and forth in coordination with the opening and closing of the flip door body 2. During the closing process, the flip door body 2 is pushed inward, and the inner surface of the flip door body 2 pushes the sliding tray 3 inward, allowing the reagent kit to enter the compartment. At this time, the locking block 500 on the pressing member 5 moves along the arc edge 201 of the flip door body 2 until it enters the slot 202 on the arc edge 201 under the action of the downward force of the spring, and the door closes. During the opening process, the lifting component 400 moves upward, lifting the clamping component 5. The locking block 500 on the clamping component 5 disengages from the slot 202 of the flip door body 2. Under the force of the torsion spring 204, the flip door body 2 moves outward. The linkage component 205 of the flip door body 2 drives the sliding tray 3 to move outward, realizing the release of the reagent kit. During the release process, although the reagent kit generates frictional resistance with the upper limit block of the rack 1, the flip door body 2 will also pop outward at a certain angle. At this time, the flip door body 2 can be opened manually.

[0029] 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.
