Description

Technical Field

[0001] This utility model relates to the field of fuse technology, specifically a fuse structure that is easy to install and disassemble. Background Technology

[0002] A fuse is an electrical component used for circuit protection. When the current exceeds a specified value, its internal fusible element melts due to heat, thereby breaking the circuit. It mainly prevents equipment damage or fire accidents caused by short circuits or overloads.

[0003] A fuse protects a circuit through a physical melting mechanism. Its core principle is that when the current abnormally rises to a set threshold, the fusible element (usually a metal such as silver or copper) melts due to the Joule effect, thus cutting off the current path. This protection mechanism features fast response (milliseconds), requires no external power supply, and has a simple and reliable structure.

[0004] Conventional fuses have a relatively fixed structure, which limits their flexibility in use when the terminals on both sides are adapted to different circuit structures. Utility Model Content

[0005] The purpose of this invention is to provide a fuse structure that is easy to install and disassemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fuse structure that is easy to assemble and disassemble, comprising a fuse assembly and a fixing ring frame. The fixing ring frame is sleeved on both the left and right ends of the fuse assembly, and an adjustment seat is connected to the bottom of the fixing ring frame. The bottom of the adjustment seat is connected to a support rail. The fuse assembly includes a fuse body, a protective shell, an observation port, a movable sleeve, and an external terminal. The fuse body is sleeved on the outside, and observation ports are opened in the middle of both sides of the protective shell. Movable sleeves are installed on both the left and right ends of the protective shell, and an external terminal is horizontally installed on the side of the movable sleeve away from the fuse body.

[0007] Furthermore, the middle section of the fuse body is made of transparent material for observing the internal fuse state, and the movable sleeve is threaded to one end of the fuse body. Moreover, one side of the movable sleeve allows the external terminal to be axially rotated and adjusted with the movable sleeve as the center.

[0008] Furthermore, the fixing ring frame includes a fixing ring body, an anti-slip pad, a support corner plate, and a reinforcing rib. The inner wall surface of the fixing ring body is covered with an anti-slip pad, and support corner plates are vertically arranged on the left and right sides of the fixing ring body, and a reinforcing rib is arranged in the middle of the support corner plate.

[0009] Furthermore, the fixing ring body, the supporting corner plate, and the reinforcing rib are integrally formed, and the horizontal end surface of the supporting corner plate is provided with an array of holes for bolt installation.

[0010] Furthermore, the adjusting seat includes a fixed seat, a damping shaft, and a connecting plate, with the damping shaft at the top center of the fixed seat and the connecting plate connected to the top of the damping shaft.

[0011] Furthermore, the bottom of the fixed base is provided with holes for bolt installation, and the damping shaft is horizontally installed at the top center of the fixed base and is used to drive the connecting plate to swing left and right for adjustment.

[0012] Furthermore, the support track includes a slide rail, a damping slider, and a limit bolt. The surface of the slide rail is slidably connected to the damping slider, and limit bolts are horizontally installed on both sides of the damping slider.

[0013] Furthermore, the damping slider and the slide rail are connected to each other using a slotted embedded structure, and the limit bolt and the damping slider are connected by a thread.

[0014] This utility model provides a fuse structure that is easy to install and disassemble, and has the following advantages: 1. This utility model features a protective shell fitted over the fuse body, with an observation port on the side of the protective shell. This structure provides excellent structural protection for the fuse body, which is made of transparent material in the middle section, ensuring the safety of the internal structure. It also allows the user to easily monitor the status of the fuse element inside the fuse body, ensuring the structural integrity of the component. Furthermore, the symmetrically arranged movable sleeves at both ends of the protective shell allow the connected external terminals to be axially adjusted horizontally using one movable end, facilitating the connection and assembly of the entire fuse assembly with the circuit. This design ensures structural flexibility, facilitates the connection and assembly of structural components, and allows for easy adjustment of the observation port to a suitable position for maintenance and observation. The fixed rings at both ends of the fusible assembly utilize a bolt-mounted hole structure on the horizontal end of the support angle plate. With the use of bolts, the entire fusible assembly can be quickly fixed to the mounting surface. Reinforcing ribs ensure the structural support and stability of the fixed ring body and the support angle plate. Anti-slip pads prevent unnecessary structural wear between the fixed ring body and the fusible assembly surface, while also ensuring the stability and firmness of the structural connection.

[0015] 2. This utility model, by setting an adjusting seat and a supporting rail, allows the fixing ring frame connected to the fuse assembly to be fixed to the surface of the connecting plate using the hole structure on the surface of the supporting corner plate and the use of bolts. This allows for quick connection and fixation of the fixing ring frame and the adjusting seat. Furthermore, the fixing seat connected to one end of the connecting plate is connected by a damping shaft. The structural adjustability of the damping shaft allows the entire supporting rail connected to the fixing seat to swing within a certain angle range, thereby achieving different structural settings for the supporting rail at different angles, thus aligning with the installation surface. The adjusting seat can slide along the surface of the slide rail using a damping slider, and the tightening of the limiting bolt controls the tightness between the adjusting slide rail and the damping slider. This structural design provides structural expansion for the installation of the fuse assembly, enabling different assembly methods on different installation surfaces. It also provides good structural adjustability, achieving structural adaptability and facilitating accurate structural connection between the entire fuse assembly and the connecting circuit, thus aiding in convenient installation.
