Technical Field

[0001] This utility model belongs to the technical field of graphite bipolar plate connection components, specifically a graphite bipolar plate connection component that can be quickly disassembled. Background Technology

[0002] Graphite bipolar plates are one of the core components in proton exchange membrane fuel cells and electrolyzers, and have functions such as conducting current, distributing reactant gases, supporting membrane electrodes, heat dissipation, and drainage.

[0003] In the current technology, the graphite bipolar plate is directly fixed to the connecting assembly, which makes it difficult to disassemble the graphite bipolar plate, makes maintenance more troublesome, and easily leads to damage to the graphite bipolar plate. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a quick-disassembly graphite bipolar plate connection assembly, thereby enabling rapid disassembly of the graphite bipolar plate connection assembly.

[0005] The technical solution of this utility model is as follows: a quick-disassembly graphite bipolar plate connection assembly, including a battery box, a cover installed on the top of the battery box, a bidirectional screw installed inside the cover, a knob fixedly connected to one end of the bidirectional screw, a threaded seat threadedly connected to the outer wall of the bidirectional screw, a sliding frame fixedly connected to the bottom end of the threaded seat, a partition fixedly connected to the bottom end of the sliding frame, an insertion hole opened on the outer wall of the partition, an insertion rod penetrating through the inner wall of the insertion hole, a connecting plate movably connected to the outer wall of the insertion rod, a connecting groove opened at the connection part between the connecting plate and the insertion rod, and a graphite bipolar plate body fixedly connected to the outer wall of the connecting plate.

[0006] Based on the above structure, the insert rod is inserted into the insertion hole, so that the insert rod is embedded in the connecting groove. Then, the threaded seat slides, causing the insert rod at the bottom of the sliding frame to slide along the inner wall of the box cover. The insertion rod slides through the connecting groove to drive the connecting plate for positioning. By fixing the connecting plates at both ends of the graphite bipolar plate body, the graphite bipolar plate body can be quickly assembled and disassembled.

[0007] Preferably, the threaded seat is provided in two sets, and the two sets of threaded seats are symmetrical about the center of the cover.

[0008] By setting two sets of threaded seats, it is easier to fix the connecting plates at both ends of the graphite bipolar plate body.

[0009] Preferably, the sliding frame forms a telescopic structure with the box cover via a bidirectional screw and a threaded seat.

[0010] When the knob is turned, the threaded seat slides through the bidirectional screw, which in turn causes the sliding bracket to slide along the inner wall of the lid.

[0011] Preferably, the partitions are equidistantly distributed along the bottom of the sliding frame, which facilitates the parallel and equidistant installation of the graphite bipolar plate body through the partitions.

[0012] Preferably, the sockets are provided in two sets, and the two sets of sockets are symmetrical about the partition.

[0013] Place the connecting plate on one side of the partition and insert the plug into the socket so that the plug is embedded in the connecting groove, thus achieving the pre-installation of the graphite bipolar plate body.

[0014] Preferably, the connecting groove is inclined.

[0015] By setting an inclined connecting groove, the insertion rod can slide through the connecting groove to drive the connecting plate for positioning, thereby improving the stability of the graphite bipolar plate body.

[0016] Preferably, the connecting plate forms a fixed structure with the partition plate through the insertion rod and the connecting groove.

[0017] In this embodiment, the sliding frame slides and drives the insertion rod at the bottom of the partition to slide synchronously. Then, the insertion rod slides and drives the connecting plate to be positioned through the connecting groove. By fixing the connecting plates at both ends of the graphite bipolar plate body, the graphite bipolar plate body can be quickly assembled and disassembled.

[0018] Compared with the prior art, the beneficial effects of this utility model are: When using this utility model, the insert rod is inserted into the insertion hole, so that the insert rod is embedded in the connecting groove. Then, the threaded seat slides, causing the insert rod at the bottom of the sliding frame to slide along the inner wall of the box cover. The sliding of the insert rod drives the connecting plate to be positioned through the connecting groove. By fixing the connecting plates at both ends of the graphite bipolar plate body, the graphite bipolar plate body can be quickly assembled and disassembled. Attached Figure Description
