Description

Technical Field

[0001] The utility model relates to a storage cylinder, and more particularly to a portable high and low voltage fuse storage cylinder. Background Art

[0002] Currently, the most commonly used short-circuit protection switch for 10kV distribution line branches and distribution transformers in my country is a drop-out fuse, with high-voltage fuses providing short-circuit protection. Low-voltage isolating switches are commonly used on the low-voltage side of transformers, with low-voltage fuses providing short-circuit protection. These two types of fuses are commonly referred to as fuses. In 10kV fault repair reports, 60% of the faults are caused by blown high- and low-voltage fuses, requiring repair personnel to bring the fuses to the fault site and replace them to restore power as quickly as possible.

[0003] Patent application publication number CN218230236U discloses a portable high- and low-voltage fuse storage cartridge, comprising a storage cartridge and a fuse body located within the cartridge. A winding post is fixedly connected to the interior of the cartridge, and the fuse body is sleeved around the winding post. A sealing cap is threadedly connected to the upper end of the cartridge, and a positioning block is fixedly connected to the center of the bottom end of the sealing cap. The positioning block has a positioning groove at its bottom end, which fits the winding post. The upper end of the winding post is inserted into the positioning groove. A squeezing mechanism is provided at the bottom end of the positioning block, and the bottom end of the squeezing mechanism contacts the top end of the fuse body. However, the following problems exist:

[0004] At present, the rear end cover of the fuse tube is often closed when it is stored, and the specifications of the stored fuse cannot be observed from the outside. The storage tube and the end cover are connected by threads, and it needs to be twisted multiple times to open when disassembling. At the same time, when the threads are not tightened and loose, the end cover is easy to fall off. When taking out the fuse in the storage tube, it is often necessary to tilt the storage tube to take out the fuse tube, which is easy to cause the fuse tube to slip out, making operation inconvenient. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a portable high and low voltage fuse storage tube, which realizes the covering connection between the storage tube and the end cover through the cooperation of strong magnetic buckles, card slots and strong magnetic blocks, making it convenient to open and close; and realizes the taking out of the fuse tube through the cooperation of the provision of a movable plate and the threaded rice, which is easy to operate.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A portable high and low voltage fuse storage tube comprises a storage tube, wherein the outer wall of one side of the storage tube is connected to a shoulder strap; a card slot is provided on the top surface of the storage tube, and a plurality of strong magnetic blocks are arranged near the edge of the card slot; the top of the storage tube is sleeved with an end cover, and the bottom surface of the end cover is fixedly connected with a strong magnetic buckle, and the strong magnetic buckle is connected to the card slot buckle for connecting the storage tube and the end cover; the inner cavity of the storage tube is provided with a movable plate, the upper surface of the movable plate is provided with a fuse tube, the lower surface of the movable plate is fixedly connected with a threaded tube, the bottom inner wall of the threaded tube is threadedly connected with a threaded rod, and the other end of the threaded rod is connected to the storage tube by a bearing, and the end of the storage tube away from the end cover is sleeved with an adjustment knob, and the output end of the adjustment knob passes through the storage tube and is connected to the threaded rod for controlling the lifting and lowering of the movable plate.

[0008] Both sides of the bottom inner wall of the storage tube are provided with strip grooves, and both side edges of the movable plate are connected with sliders, and the sliders are embedded in the strip grooves.

[0009] A plurality of limiting grooves are arranged on the upper surface of the movable plate, and fuse cylinders are arranged in the limiting grooves.

[0010] A winding column is fixedly arranged inside the fuse barrel and is used to surround the fuse body.

[0011] A fuse tube cover is sleeved on the top of the fuse tube, a spring is connected to the bottom of the fuse tube cover, and an extrusion ring is connected to the other end of the spring. The extrusion ring is adapted to the size of the fuse tube, and a through groove is provided in the middle of the extrusion ring. The top of the winding column passes through the middle through groove of the extrusion ring, and the winding column is adapted to the size of the through groove provided in the middle of the extrusion ring.
