Description

Technical Field

[0001] This utility model relates to the field of low-voltage distribution cabinet technology, specifically to a built-in surge protector for a low-voltage distribution cabinet. Background Technology

[0002] In the operational architecture of modern power systems, it plays a crucial and irreplaceable role. As the core hub for power distribution and control, it receives and rationally distributes electrical energy from upstream power sources, providing a stable and reliable power supply for numerous low-voltage electrical devices.

[0003] In practical use, surge protectors are typically mechanically fixed with fasteners or directly bonded. As the equipment is used over time, surge protectors fixed with fasteners will experience continuous vibration during the daily operation of the distribution cabinet. This vibration comes from the operation of internal electrical equipment, causing the fasteners to gradually loosen, reducing the friction between the threads, resulting in a less tight connection and eventually causing the fasteners to fall off. As for direct bonding, the adhesive will gradually age, reducing its bonding strength. Once the fasteners loosen and fall off or the bonding strength decreases, the surge protector may fall off its installation position. Utility Model Content

[0004] The purpose of this utility model is to provide a built-in surge protector for low-voltage distribution cabinets to solve the problems mentioned in the background section. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-3 As shown, this utility model is a built-in surge protector for a low-voltage distribution cabinet, comprising:

[0029] Protector housing 100;

[0030] The fixing component includes a side plate 200, a movable groove 202, a fixing screw 203, a fastening ring 204, and a movable block 205. The side plate 200 is fixed to the upper part of both sides of the outer surface of the protector shell 100. The fixing screw 203 is threaded into the inside of the side plate 200. The movable groove 202 is opened in the upper and lower parts of both sides of the outer surface of the protector shell 100. The fastening ring 204 is sleeved on the outer surface of the fixing screw 203. The movable block 205 is disposed on one side of the fastening ring 204 and is movably connected to the inside of the movable groove 202.

[0031] After the fixing screw 203 passes through the side plate 200 and completes the initial fixing of the protector shell 100, the moving block 205 can slide smoothly in the moving groove 202, so that the fastening ring 204 is sleeved on the outside of the fixing screw 203 to position the fixing screw 203.

[0032] The fixing component also includes a pole 201, which is welded between two fastening rings 204;

[0033] The two fastening rings 204 are supported by the upright 201.

[0034] It also includes a locking component, which includes a limiting plate 304, an insert plate 305 and a slot 306. The slot 306 is opened inside the fixing screw 203 and the fastening ring 204. The insert plate 305 is inserted and connected inside the slot 306. The limiting plate 304 is fixed to the top of the insert plate 305.

[0035] After the fastening ring 204 is fitted onto the outside of the fixing screw 203, the insert plate 305 is inserted into the inside of the slot 306, so that the fastening ring 204 is fixed to the outside of the fixing screw 203.

[0036] A support rod 300 is fixed to the top of the fastening ring 204. A spring 302 is wound around the outer surface of the support rod 300 and passes through the interior of the limiting plate 304. A handle 303 is fixed to the middle of the top of the limiting plate 304.

[0037] The spring 302 generates elastic force, which allows the insert plate 305 to be lifted out.

[0038] A limiting plate 301 is fixed to the top of the support rod 300, and a spring 302 is attached to the top of the limiting plate 304.

[0039] Working principle: First, the protector housing 100 is attached to the inner wall of the distribution cabinet, and the side plate 200 is attached simultaneously. The side plate 200 and the distribution cabinet are fixed together using fixing screws 203. After the fixing screws 203 pass through the side plate 200 and complete the initial fixing of the protector housing 100, the moving block 205 can slide smoothly within the moving groove 202. The operator only needs to hold the handle 303 to easily lift the insert plate 305 upwards. At this time, the fastening ring 204 can be smoothly fitted onto the outside of the fixing screw 203. Then, the spring... Spring 302 quickly rebounds, pushing insert plate 305 to precisely insert into slot 306. After this action is completed, a solid locking structure is formed, effectively locking the position of fixing screw 203. During the daily operation of the distribution cabinet, the vibration generated by the internal electrical equipment is complex and continuous. However, through the tight cooperation between insert plate 305 and slot 306, and the stable pressure provided by spring 302, fixing screw 203 is firmly fixed in its original position, effectively avoiding loosening caused by vibration.

[0040] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0041] The movable component includes a support bar 400, a slide groove 403, and a slider 404. The support bar 400 is installed at one end of the outer surface of the protector housing 100, the slide groove 403 is formed inside the support bar 400, and the slider 404 is fixed at one end of the outer surface of the protector housing 100 and is movably connected inside the slide groove 403.

[0042] The support bar 400 can be installed inside the distribution cabinet. The protector housing 100 can be moved to the required height by sliding the slider 404 inside the slide groove 403 without repeated disassembly and assembly. The fixing screw 203 and the support bar 400 can be used selectively.

[0043] The top and bottom of the support bar 400 are fixed with fixing plates 401, and a fixing rod 402 is inserted into the middle of the fixing plate 401.

[0044] The support bar 400 is fixed by inserting the fixing rod 402 into the fixing plate 401 and the inside of the distribution cabinet.

[0045] The working principle involves inserting a fixing rod 402 into the fixing plate 401 and the inside of the distribution cabinet, allowing the support bar 400 to be securely installed inside the distribution cabinet. The support bar 400 is provided with a sliding groove 403, and the protector housing 100 is equipped with a matching slider 404, allowing the protector housing 100 to slide smoothly on the support bar 400. The operator can easily move the protector housing 100 to the required height position by simply using the sliding function of the slider 404 within the sliding groove 403. In actual use, the user can selectively use the fixing screw 203 and the support bar 400 to fix the protector housing 100 according to the specific situation. For example, when it is necessary to fix the protector housing 100 at a specific height and high stability is required, the fixing screw 203 can be used for further reinforcement. In some scenarios where height adjustments are more frequent, the basic usage requirements can be met by relying solely on the cooperation of the support bar 400 and the slider 404, without the need to use the fixing screw 203 every time.
