Description

Technical Field

[0001] This utility model relates to the field of fuse device technology, and in particular to a simple fuse device for easy activation and deactivation. Background Technology

[0002] The most common type of fuse on the market is the cylindrical fuse and its base assembly. This assembly uses a cylindrical cap structure with the fuse core housed inside, connected to a cover plate. Removing the cover plate engages the fuse, while pulling it out removes it. However, this design results in a tight fit between the cover plate and the base, leading to a small contact area and limited torque when removing the fuse, requiring significant effort. This also affects the locking mechanism, causing it to become either too tight or loose. Especially after prolonged periods of operation, fuse assemblies can become severely jammed, requiring considerable force to remove them and potentially causing mechanical damage. Furthermore, in environments with large-scale fuse usage, such as manufacturing plants, removing a large number of fuses due to this jamming mechanism requires significant time and reduces efficiency. The repetitive and laborious nature of this task can also lead to worker injuries. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a simple fuse activation / deactivation device. To achieve the above objectives, this utility model adopts the following technical solution:

[0004] A simple fuse activation / deactivation device includes a rotary operating device, a fixed base, and a connecting shaft. One end of the rotary operating device is movably connected to the fixed base via the connecting shaft. The rotary fixing mechanism in the rotary operating device can be fixed by engaging with the locking surface in the fixed base via a lever. The fixed base has a cavity inside for accommodating the rotary operating device. Bases are symmetrically installed on both sides of the bottom of the fixed base.

[0005] The rotating operating device includes a movable cover plate and a rotating fixing mechanism. One end of the movable cover plate is connected to the connecting shaft, and a storage device is provided on the side of the movable cover plate near the fixed base. One end of the connecting plate of the rotating fixing mechanism is fixedly connected to the movable cover plate.

[0006] The rotating fixing mechanism includes a paddle, a rotating shaft, and a connecting plate, with the rotating shaft connected to the paddle and the connecting plate respectively.

[0007] When the rotating operating device is closed with the fixed base, the connecting plate of the rotating fixing mechanism is adapted to and in contact with the edge of the fixed base cavity.

[0008] The paddle has multiple protruding friction surfaces on the side facing the fixed base, and the paddle is parallel to the opening and closing surface of the movable cover plate.

[0009] The aforementioned paddle is designed to rotate only via a rotating shaft toward the storage device.

[0010] The storage device is a cylindrical clamp composed of multiple coils, used to install the fuse of the fuse device.

[0011] The fixed base has a locking surface with a locking recess structure on one side of the opening.

[0012] The rotating cover plate of the rotating operating device rotates, causing the connecting plate to contact the edge of the fixed base cavity. When the connecting plate contacts the edge of the fixed base cavity, the paddle rotates through the rotating shaft and engages with the locking surface of the locking recess structure.

[0013] The fixed base has a buffer pad layer on the edge near the locking surface.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, a rotating paddle is connected to a fixed base.

[0020] To better understand the purpose, structure, and function of this utility model, the silane recovery system of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] A simple fuse activation / deactivation device includes a rotary operating device 1, a fixed base 2, and a connecting shaft 3. One end of the rotary operating device 1 is movably connected to the fixed base 2 via the connecting shaft 3. The rotary fixing mechanism 13 in the rotary operating device 1 is fixed by engaging with the locking surface 24 in the fixed base 2 via a lever 133. The fixed base 2 has a cavity inside to accommodate the rotary operating device 1, and bases 22 are symmetrically installed on both sides of the bottom of the fixed base 2. The lever 133 in the rotary operating device 1 rotates and opens / closes via the connecting shaft 3, engaging with the locking surface 24 of the fixed base 2, improving the ease of opening and closing, allowing for quick activation / deactivation of the fuse storage device 12, thereby improving work efficiency.

[0022] Furthermore, the rotating operating device 1 includes a movable cover plate 11 and a rotating fixing mechanism 13. One end of the movable cover plate 11 is connected to the connecting shaft 3, and a storage device 12 is provided on the side of the movable cover plate 11 near the fixed base 2. One end of the connecting plate 131 of the rotating fixing mechanism 13 is fixedly connected to the movable cover plate 11. When the storage device 12 is placed in the storage device 12 on the side of the movable cover plate 11 near the fixed base 2, the rotating operating device 1 rotates the connecting shaft 3 to place the storage device 12 into the cavity of the fixed base 2. At the same time, the connecting plate 131 rigidly transmits the operating force of the movable cover plate 11 during rotation, increasing the torque effect.

[0023] Furthermore, the rotating fixing mechanism 13 includes a paddle 133, a rotating shaft 132, and a connecting plate 131, with the rotating shaft 132 connected to both the paddle 133 and the connecting plate 131. This allows the paddle 133 to rotate via the rotating shaft 132, increasing the contact area for the operator to open the rotating operating device 1, thereby increasing opening and closing efficiency and overall work efficiency.

[0024] Furthermore, when the rotating operating device 1 is closed with the fixed base 2, the connecting plate 131 of the rotating fixing mechanism 13 is adapted to and in contact with the edge of the cavity of the fixed base 2. When the connecting plate 131 contacts the fixed base 2, the lever 133 rotates.

[0025] Furthermore, the lever 133 has multiple protruding friction surfaces 1331 on the side facing the fixed base 2, and the lever 133 is parallel to the opening and closing surface of the movable cover plate 11. By rotating the lever 133 to be parallel to the opening and closing surface of the movable cover plate 11, the lever torque is increased, and at the same time, the protruding friction surfaces 1331 on one side of the lever 133 increase the frictional force of the operator opening and closing the rotating operating device 1.

[0026] Furthermore, the paddle 133 is designed to rotate only towards the storage device 12 via the rotating shaft 132. The rotation of the paddle 133 and the rotating shaft 132 further enhances the convenience of the rotary opening and closing operation device 1, while avoiding safety hazards to operators caused by jamming or difficulty in opening and closing.

[0027] In use, rotate the lever 133 until the movable cover 11 is parallel to its opening and closing surface, causing the movable cover 11 to open and close, placing the safety device 12 inside. Then close the movable cover 11 to place the storage device 12 inside the cavity of the fixed base 2. The connecting plate 131 contacts the edge of the fixed housing 21, and the lever 133 is rotated by the rotating shaft 132 to engage with the locking surface 24 of the locking recess structure on the side of the fixed base 2.

[0028] Furthermore, the storage device 12 is a cylindrical clamp composed of multiple coils, used to install the fuse of the fuse device. The cylindrical clamp composed of multiple coils increases the convenience of securing the fuse when the rotating operating device 1 is opened.

[0029] Furthermore, the fixed base 2 has a locking surface 24 with a locking recess structure on one side of the opening. The locking recess structure on one side of the fixed base 2 engages with the friction surface 1331 of the protruding structure on one side of the lever 133, preventing loosening caused by vibration and further increasing the overall locking effect of the device.

[0030] Furthermore, the rotating cover plate 11 of the rotating operating device 1 rotates, causing the connecting plate 131 to contact the edge of the cavity of the fixed base 2. When the connecting plate 131 contacts the edge of the cavity of the fixed base 2, the lever 133 rotates through the rotating shaft 132 and engages with the locking surface 24 of the locking recess structure. The engagement of the lever 133 with the locking surface 24 improves the locking effect of the device while increasing the ease of opening and closing the device.

[0031] Furthermore, the fixed base 2 has a buffer pad 23 on the edge near the locking surface 24. The buffer pad 23 prevents hard contact between the connecting plate 131 and the fixed housing 21, reducing the loosening of the closure caused by contact between the connecting plate 131 and the fixed object.

[0032] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The embodiments and features described in this application can be arbitrarily combined without conflict. The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
