Description

Technical Field

[0001] This utility model relates to the field of equipment opening and closing structure technology, specifically to a switch cover structure that enables pipe fittings to be precisely connected to containers, applicable to various types of equipment that require pipe fittings to be fixed and connected to containers via a cover. Background Technology

[0002] In chemical, medical, and testing fields, many devices (such as titrators, reaction vessels, and liquid analyzers) require tubing on the cover to connect with containers inside the equipment for fluid transport or signal transmission. Existing equipment often uses a hinged connection between the cover and the casing, with the tubing fixed to the cover and rotating synchronously. This structure has significant drawbacks: when opening and closing the cover, the tubing tilts as it rotates. If the tubing length is appropriate for the container depth, it is prone to bumping against the container's inner wall during rotation, leading to tubing damage or container displacement. Conversely, shortening the tubing length prevents precise docking with the container, affecting equipment functionality. Therefore, developing a cover structure that allows for precise docking of the tubing with the container is a key requirement for solving these problems. Summary of the Invention

[0003] The utility model aims to overcome the aforementioned defects in the existing opening and closing structures of equipment, and provides a switch cover structure that enables precise docking of pipe fittings with containers, including a housing, a cover, a flipping bracket, a lifting column, and a positioning assembly. The flipping bracket is separate from the housing and hinged to the cover.

[0004] The lifting column consists of at least two columns, with their fixed ends vertically installed inside the machine housing and their movable ends connected to a tilting bracket. This allows the tilting bracket and the machine cover to be lifted and lowered vertically, enabling the pipe fittings to be separated from or aligned with the container to be docked in the vertical direction.

[0005] The positioning component consists of a positioning pin fixed on the cover and a positioning bayonet adapted on the flip bracket. When closed, the positioning bayonet engages with the positioning pin, limiting excessive flipping of the cover and ensuring vertical and accurate docking of the pipe fittings.

[0006] Compared with conventional equipment opening and closing structure technology, this utility model has the following beneficial effects.

[0007] This utility model completely avoids collisions between pipes and containers by using a two-step opening and closing method of "vertical lifting + flipping", protecting both pipes and containers and reducing equipment maintenance costs. The locking structure of the positioning component can accurately fix the closed position of the cover, ensuring vertical docking of pipes and improving the reliability of equipment functions. The structure is simple, the parts are easy to obtain, the lifting stroke is adjustable, and it is compatible with various pipes such as infusion tubes and catheters, as well as containers of different heights. It can be applied to various equipment such as titrators, reaction vessels, and detectors, and has strong versatility. Attached Figure Description

[0013] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention is not limited to the specific embodiments disclosed below.

[0014] Please refer to Figure 1-3 The switch cover structure in this embodiment, which enables the pipe to be precisely connected to the container, includes a container to be connected 1, a pipe 2, a housing 3, a cover 4, a pipeline channel 5, a flip bracket 6, a lifting column 7, a positioning pin 8, and a positioning bayonet 9.

[0015] In this embodiment, the flipping bracket 6 is hinged to the cover 4. The cover 4 has a fixed pipeline channel 5 inside, and the pipe 2 passes through the pipeline channel 5. One end of the pipe 2 passes through the side of the cover 4 and connects to the external reagent delivery device, while the other end is suspended. The lifting column 7 has a stroke of 5cm. The fixed end is fixed to the housing 3 with bolts, and the movable end is connected to the flipping bracket 6. The positioning pin 8 is fixed on the cover 4. There is a positioning slot 9 at the corresponding position of the flipping bracket 6. When closed, the positioning slot 9 engages with the positioning pin 8, which limits the excessive flipping of the cover 4 and ensures that the pipe 2 is vertically and accurately connected to the container 1.

[0016] When the structure needs to be opened, the operator sends an opening signal through the external control system. The push rods of the two lifting columns 7 extend upward by 5cm simultaneously, driving the tilting bracket 6 and the cover 4 to rise vertically. The pipe 2 is then vertically pulled out of the container 1 to be docked. Subsequently, the operator tilts the cover 4 upward, and the pin of the tilting bracket 6 rotates 100°, so that the cover 4 is fully opened, which facilitates operations such as container loading and unloading and material addition.

[0017] When closing, first flip the cover 4 downwards until the positioning slot 9 on the flipping bracket 6 aligns with the positioning pin 8 and engages, preventing the cover 4 from continuing to flip; the control system controls the push rods of the two lifting columns 7 to retract downwards by 5cm simultaneously, causing the cover 4 to descend vertically, and the pipe 2 is inserted into the container 1 to be docked in the vertical direction, with the lower end extending 5cm below the liquid surface, completing the closure, and subsequent fluid transfer operations can be started.

Claims

1. A switch cover structure enabling precise docking of pipe fittings with containers, comprising a housing and a cover, characterized in that, It also includes a flipping bracket, a lifting column, and a positioning assembly. The flipping bracket is separate from the housing and hinged to one side of the cover to provide support for the flipping of the cover. There are at least two lifting columns, which are vertically installed inside the housing. The fixed end of the lifting column is fixedly connected to the bottom of the housing, and the movable end is fixedly connected to the flipping bracket to drive the flipping bracket and the cover to move vertically. The positioning assembly includes a positioning pin and a positioning latch. The positioning pin is fixed to the cover, and the positioning latch is opened on the side of the flipping bracket facing the positioning pin. The positioning latch is adapted to the positioning pin. When the cover is flipped to the closed position, the positioning latch engages with the positioning pin, restricting the cover from continuing to flip and making the pipes on the cover vertically aligned with the container to be docked.

2. The switch cover structure according to claim 1, which enables precise docking of pipe fittings with containers, is characterized in that, When opening, the lifting column first drives the tilting bracket and the cover to rise vertically, so that the pipe on the cover is completely detached from the container to be docked. Then the tilting bracket drives the cover to tilt around the hinge and open. When closing, the tilting bracket first drives the cover to tilt downward around the hinge to the locking position until the locking slot aligns with the locking pin and locks in place. After the locking assembly completes the locking and positioning, the lifting column then drives the tilting bracket and the cover to descend vertically, so that the pipe is inserted into the container to be docked.
