[0002] In power distribution network construction, integrated primary and secondary ring main units serve as core equipment for connecting power distribution lines and realizing power distribution and control. They integrate primary equipment such as circuit breakers and load switches with secondary equipment such as relay protection and monitoring and control terminals, and are widely used in power distribution scenarios such as urban residential areas and industrial parks. Their operational stability is directly related to the reliability of regional power supply, and routine maintenance and fault diagnosis are key links to ensure the continuous and reliable operation of the equipment.
[0003] However, the sealing and protection of existing ring main unit installation slots generally rely on multiple sets of bolts to rigidly fix the cabinet door to the box body. The primary and secondary equipment inside are directly locked to the inner wall of the box or fixed brackets by bolts. During maintenance, not only do tools such as wrenches need to be used to remove the bolts one by one to open and close the cabinet door, but tools are also needed to disassemble the fixed parts when maintaining or replacing the equipment. In case of emergency repairs, the maintenance progress is easily delayed. Utility Model Content
[0004] The purpose of this utility model is to provide a primary and secondary integrated ring mesh box that is easy to maintain in order to solve the above problems. Pressing the pressure block can compress the telescopic spring, which drives the insert block to disengage from the slot. After releasing the pressure block, the elastic force of the telescopic spring pushes the pressure block back, which drives the insert block to automatically insert into the slot, realizing automatic locking after the cabinet door is closed, making the opening of the maintenance entrance more efficient.
[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a primary and secondary integrated ring network box that is easy to maintain, comprising a ring network box, the interior of which is provided with several mounting slots, a base plate fixed to the mounting slot, a cabinet door rotatably mounted on the base plate, a locking mechanism slidably mounted on the cabinet door, the locking mechanism including a pressure block and a telescopic spring, the pressure block slidably mounted on the cabinet door, a connecting rod fixed inside the cabinet door, a telescopic spring sleeved on the connecting rod, the pressure block abutting against the telescopic spring, a fixing block mounted on the side wall of the cabinet door away from the pressure block, an insert block slidably mounted inside the fixing block, the insert block being fixedly connected to the pressure block, and a slot provided near the insert block in the ring network box, the slot being locked with the insert block.
[0006] Preferably, the pressure block and the connecting rod are slidably connected, and the insert block and the ring network box are engagingly connected.
[0007] Preferably, the engaging mechanism further includes abutments, and two abutments are symmetrically fixedly connected to the slot inside the ring mesh box, with the abutments contacting the side wall of the cabinet door.
[0008] Preferably, the cabinet door and the ring mesh box are interlocked, and a handle is fixedly installed on the side wall of the cabinet door away from the insertion block.
[0009] Preferably, two sliding grooves are symmetrically provided in both the base plate and the cabinet door, and the height of the base plate near the sliding groove is greater than the height of the cabinet door near the sliding groove.
[0010] Preferably, an installation mechanism is slidably mounted inside the base plate. The installation mechanism includes a mounting frame and a slider. Two sets of sliders are slidably mounted inside the base plate. The mounting frame is fixedly connected to the slider. Rollers are rotatably mounted inside the slider.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-7 As shown, a primary and secondary integrated ring main unit for easy maintenance includes a ring main unit 1. The ring main unit 1 has several mounting slots 7 inside. A base plate 2 is fixed to the mounting slots 7. A cabinet door 4 is rotatably mounted on the base plate 2. A locking mechanism 6 is slidably mounted on the cabinet door 4. The locking mechanism 6 includes a pressure block 601 and a telescopic spring 603. The pressure block 601 is slidably mounted on the cabinet door 4. A connecting rod 602 is fixed inside the cabinet door 4. The telescopic spring 603 is sleeved on the connecting rod 602. The pressure block 601 abuts against the telescopic spring 603. A fixing block 607 is installed on the side wall of the cabinet door 4 away from the pressure block 601. An insert block 604 is slidably mounted inside the fixing block 607. The insert block 604 and the pressure block 601 are fixedly... The ring mesh box 1 has a slot 605 near the insert block 604. The insert block 604 is engaged with the slot 605. The pressure block 601 is slidably connected to the connecting rod 602. The insert block 604 is engaged with the ring mesh box 1. The pressure block 601 slides along the connecting rod 602 fixed inside the cabinet door 4 and compresses the telescopic spring 603 sleeved on the connecting rod 602. When the pressure block 601 slides, it can synchronously drive the insert block 604 fixed to it to move. The insert block 604 slides into the fixed block 607, so that the cabinet door 4 and the ring mesh box 1 can be engaged together. There are two abutments 606 symmetrically fixedly connected to the slot 605 inside the ring mesh box 1. The abutments 606 contact the side wall of the cabinet door 4.
[0024] As a technical optimization of this utility model, the cabinet door 4 and the ring mesh box 1 are connected by a snap-fit connection, and the plug 604 and the slot 605 are engaged to ensure that the cabinet door 4 is aligned and sealed after closing, which is beneficial to improving the protective effect of the cabinet door 4; a handle 5 is fixedly installed on the side wall of the cabinet door 4 away from the plug 604.
[0025] As a technical optimization of this utility model, two sliding grooves 3 are symmetrically provided in the bottom plate 2 and the cabinet door 4. The bottom plate 2 is fixed in the mounting groove 7 of the ring mesh box 1 by bolts to ensure that the sliding groove 3 on the bottom plate 2 is aligned with the sliding groove 3 provided on the inner side of the cabinet door 4. The cabinet door 4 is rotatably installed on the bottom plate 2. The cabinet door 4 can be flexibly opened and closed around the edge of the bottom plate 2, thereby sealing the mounting groove 7. Moreover, the height of the bottom plate 2 near the sliding groove 3 is greater than the height of the cabinet door 4 near the sliding groove 3.
[0026] As a technical optimization of this utility model, an installation mechanism 8 is slidably mounted inside the base plate 2. The installation mechanism 8 includes an installation frame 801 and a slider 802. Two sets of sliders 802 are slidably mounted inside the base plate 2. The installation frame 801 is fixedly connected to the slider 802. A roller 803 is rotatably mounted inside the slider 802. The roller 803 is rotatably connected to the base plate 2 and the cabinet door 4. The installation frame 801 is L-shaped. By holding the edge of the installation frame 801, the slider 802 fixed at its bottom end is pushed to slide along the slide groove 3 provided inside the base plate 2, thereby sending the equipment into the installation groove 7. When the slider 802 slides, the roller 803 rotatably mounted inside the slider 802 contacts and rolls with the inner wall of the base plate 2, thereby reducing the sliding resistance of the installation frame 801. The width of the slider 802 is equal to the width of the slide groove 3, and the installation frame 801 is located in the installation groove 7.
[0027] In use, the base plate 2 is first fixed to the mounting groove 7 of the ring mesh box 1 with bolts, ensuring that the sliding groove 3 on the base plate 2 is aligned with the sliding groove 3 on the inner side of the cabinet door 4. The cabinet door 4 is rotatably mounted on the base plate 2, and the cabinet door 4 can be flexibly opened and closed around the edge of the base plate 2, thereby sealing the mounting groove 7. During equipment installation, the primary and secondary equipment are fixed to the mounting frame 801 with an L-shaped structure with bolts. Then, the edge of the mounting frame 801 is held, and the slider 802 fixed at its bottom end is pushed along the sliding groove 3 provided in the base plate 2. The sliding mechanism allows the equipment to be inserted into the mounting slot 7. When the slider 802 slides, the roller 803 mounted inside the slider 802 contacts and rolls against the inner wall of the base plate 2, thus reducing the sliding resistance of the mounting bracket 801. After the equipment is installed, the cabinet door 4 is rotated, and the pressure block 601 inside the cabinet door 4 is pressed. The pressure block 601 slides along the connecting rod 602 fixed inside the cabinet door 4, compressing the telescopic spring 603 sleeved on the connecting rod 602. The sliding of the pressure block 601 synchronously drives the fixed insert block 604 to move. Sliding into the fixing block 607 allows the cabinet door 4 to engage with the ring mesh box 1. A stop block 606 is fixed to the ring mesh box 1 near the cabinet door 4. When the cabinet door 4 contacts the stop block 606, the pressure block 601 can be released. The elastic spring 603 returns to its original position, pushing the pressure block 601 back to its original position. This, in turn, causes the insert block 604 to slide out of the fixing block 607 and insert into the slot 605 inside the ring mesh box 1. The insert block 604 and slot 605 engage to ensure a proper seal after the cabinet door 4 is closed, facilitating the lifting and sealing of the cabinet door 4. Protection effect: When it is necessary to remove the primary and secondary equipment from the mounting slot 7 for maintenance, press the pressure block 601 to reopen the cabinet door 4, rotate the cabinet door 4 to align with the base plate 2, which can form a through sliding channel. Then pull out the mounting bracket 801, which can make the slider 802 drive the roller 803 to roll along the slide groove 3. The slide groove 3 restricts the slider 802 from deflecting, ensuring that the mounting bracket 801 drives the equipment to enter and exit in the preset direction. In this way, the mounting bracket 801 can be moved to the cabinet door 4, and the equipment can be pulled out of the mounting slot 7 without disassembling it, thus expanding the maintenance operation space.
