Abstract
Description
Technical Field
[0001] This utility model relates to the field of arc extinguishing cover technology, specifically to a riveting structure for an arc extinguishing cover. Background Technology
[0002] As a core component of electrical equipment, the arc-extinguishing enclosure's connection stability with external structures (such as circuit breaker housings and switchgear frames) directly affects the overall operational safety of the equipment. In actual assembly, the connection direction between the arc-extinguishing enclosure and external structures needs to be flexibly adjusted according to the equipment layout to adapt to different installation spaces and operating conditions.
[0003] Currently, most connections between arc-extinguishing chambers and external structures are made using welding or threaded connections, which have significant limitations in terms of flexibility in connection direction. While welding provides a stable connection in a fixed direction, the connection direction is entirely determined by the welding position and cannot be adjusted once welding is completed. When the installation direction of the external connection structure changes or there are layout deviations, re-welding is necessary. This not only further damages the arc-extinguishing chamber material properties due to high temperatures (especially affecting sensitive materials such as ceramics and arc-resistant plastics), but also increases the risk of component deformation and cracking, significantly reducing the product qualification rate.
[0004] While threaded connections allow for adjustment of the connection angle within a certain range, this adjustment range is extremely limited due to the fixed direction of the threaded hole. To achieve a non-axial or non-radial inclined connection, an additional inclined threaded hole needs to be machined on the arc-extinguishing shield or external structure. This process is difficult and requires high precision. Furthermore, the threads are prone to stripping or breaking under inclined forces, leading to connection failure. Utility Model Content
[0005] This utility model provides a riveting structure for an arc-extinguishing cover, which solves the problem that most existing arc-extinguishing covers and external connection structures are connected by welding or threaded connections, which have obvious shortcomings in terms of flexibility in connection direction.
[0006] This utility model provides the following technical solution: a riveting structure for an arc-extinguishing shield, including an arc-extinguishing shield shell, and further comprising:
[0007] Connecting plates are installed on both sides of the arc-extinguishing shroud shell. A telescopic mechanism is fixedly connected to the surface of the connecting plates. The telescopic mechanism includes an electric push rod, a storage battery, and a fixing plate.
[0008] A mounting plate is set at the bottom of the fixed plate. Both sides of the surface of the mounting plate are threaded with threaded plates. A riveting mechanism is fixedly connected to the surface of the threaded plates. The riveting mechanism includes an elastic pad, a limit block, and a positioning block.
[0009] As a preferred embodiment of this utility model, the electric push rod is fixedly connected to the surface of the connecting plate, one side of the electric push rod is electrically connected to a battery via a power line, and the output end of the electric push rod is fixedly connected to a fixing plate.
[0010] In a preferred embodiment of this utility model, the elastic pad is fixedly connected to the surface of the threaded plate, a limiting block is fixedly connected to the end of the elastic pad, and a positioning block is inserted into the surface of the limiting block.
[0011] As a preferred embodiment of this utility model, a fixing cylinder is fixedly connected to the surface of the connecting plate, and a supporting spring is fixedly connected inside the fixing cylinder.
[0012] As a preferred embodiment of this utility model, a telescopic rod is fixedly connected to one side of the support spring, and the telescopic rod is slidably connected inside the fixed cylinder.
[0013] As a preferred embodiment of this utility model, the lower surface edge of the arc-extinguishing cover is provided with two extension plates, and the extension plates have a limiting groove inside.
[0014] As a preferred embodiment of this utility model, a telescopic plate is slidably connected inside the limiting groove, and one side of the telescopic plate is fixedly connected to one side of the mounting plate.
[0015] As a preferred embodiment of this utility model, an annular sealing ring is fixedly connected to the bottom of the arc-extinguishing shroud shell, and a connecting spring is installed inside the annular sealing ring.
[0016] Compared with the prior art, the present invention provides a riveting structure for an arc-extinguishing shield, which has the following beneficial effects:
[0017] The riveting structure of this arc-extinguishing hood, through the setting of the riveting mechanism, allows for quick positioning of the arc-extinguishing hood shell by pressing down on the elastic pad during use. This is achieved by moving the limiting block at the end of the elastic pad to the appropriate position, then moving the outer shell of the arc-extinguishing hood into the positioning block, and aligning the limiting block with the positioning grooves on both sides of the positioning block. Finally, the elastic pad is released, allowing the limiting block on the elastic pad to insert into the positioning groove on the positioning block. This is more convenient than welding and bolting connections.
[0018] The riveting structure of the arc extinguishing hood, through the setting of the telescopic mechanism, allows the power to be turned on during equipment installation, activating the electric push rods on both sides. The electric push rods extend and retract, driving the mounting plate under the end fixing plate to adjust its position, thereby adjusting the position of the riveting structure on the mounting plate. This enables the riveting structure to accurately adapt to the installation direction and position of the external connection structure, improving the flexibility and adaptability of the arc extinguishing hood shell and the external connection structure in the connection direction.

[0026] Connecting plates 2 are installed on both sides of the arc-extinguishing chamber shell 1. Telescopic mechanisms 3 are fixedly connected to the surface of the connecting plates 2. The telescopic mechanism 3 includes an electric push rod 301, a battery 302, and a fixing plate 303.
[0027] The mounting plate 4 is set at the bottom of the fixed plate 303. Both sides of the surface of the mounting plate 4 are threadedly connected to the threaded plates 5. The surface of the threaded plates 5 is fixedly connected to the riveting mechanism 6, which includes an elastic pad 601, a limit block 602 and a positioning block 603.
[0028] Specifically, the electric push rod 301 is fixedly connected to the surface of the connecting plate 2, and a battery 302 is electrically connected to one side of the electric push rod 301 via a power cord. The output end of the electric push rod 301 is fixedly connected to a fixing plate 303.
[0029] In this embodiment, when installing the equipment, the power is turned on and the electric push rods 301 on both sides are started. The electric push rods 301 extend and retract, and drive the mounting plate 4 below the end fixing plate 303 to adjust its position, thereby adjusting the position of the riveting structure on the mounting plate 4.
[0030] Specifically, the elastic pad 601 is fixedly connected to the surface of the threaded plate 5, and the end of the elastic pad 601 is fixedly connected to the limit block 602, and the surface of the limit block 602 is inserted with the positioning block 603.
[0031] In this embodiment, during use, the elastic pad 601 is pressed down so that the limiting block 602 at the end of the elastic pad 601 moves to a suitable position. Then, the arc extinguishing cover 1 is moved into the positioning block 603, and the limiting block 602 is aligned with the positioning grooves on the two side positioning blocks 603. Finally, the elastic pad 601 is released so that the limiting block 602 on the elastic pad 601 is inserted into the positioning groove on the positioning block 603.
[0032] Specifically, a fixing cylinder 7 is fixedly connected to the surface of the connecting plate 2, and a support spring 8 is fixedly connected inside the fixing cylinder 7.
[0033] In this embodiment, the fixed cylinder 7 facilitates the support of the telescopic rod 9, allowing it to slide inside the fixed cylinder 7.
[0034] Specifically, a telescopic rod 9 is fixedly connected to one side of the supporting spring 8, and the telescopic rod 9 is slidably connected inside the fixed cylinder 7.
[0035] Specifically, the lower surface edge of the arc extinguishing cover 1 is provided with two extension plates 10, and the extension plates 10 have limit grooves inside.

Finally, release the elastic pad 601 so that the limiting block 602 on the elastic pad 601 is inserted into the positioning groove on the positioning block 603.
[0040] When installing the equipment, turn on the power and start the electric push rods 301 on both sides. The electric push rods 301 extend and retract and drive the mounting plate 4 below the end fixing plate 303 to adjust the position, thereby adjusting the position of the riveting structure on the mounting plate 4.
