Description

Technical Field

[0001] This utility model relates to the field of meter box technology, and in particular to a meter box that is easy to install. Background Technology

[0002] Easy-to-install meter boxes, while fulfilling the functions of protecting and metering meters and electrical components, reduce installation difficulty and time through optimized structure, pre-installed accessories, and simplified operation. They are suitable for various scenarios, such as residential, commercial, and outdoor meter storage and protection devices. Installers can quickly complete the entire process of fixing the box, installing components, and wiring and debugging without complex processing or special tools.

[0003] Some meter boxes are wall-mounted, with pre-designed cable entry points at the bottom. In outdoor environments with many mosquitoes, insects can easily enter the meter box through these entry points, causing electrical malfunctions. Currently, most meter boxes use tape to wrap the cables, making them contact the cable entry points. While this effectively reduces the possibility of insects entering, the tape wrapping requires repeated adjustments based on the cable diameter. Furthermore, when cables need repair or replacement, the tape must be peeled off piece by piece. If the tape is too tight, tools are needed to remove it, which can damage the cable's insulation and create safety hazards. Therefore, the installation process remains time-consuming and maintenance is inconvenient. Utility Model Content

[0004] The main purpose of this utility model is to provide an easy-to-install meter box to enable the rapid installation of the cable sealing structure, thereby indirectly improving the convenience of cable maintenance.

[0005] The technical solution of this utility model is as follows:

[0006] An easy-to-install electric meter box includes an electric meter box body and a cable threading hole. The bottom of the electric meter box body is provided with a sealing mounting groove, the cable threading hole is located in the sealing mounting groove, and a quick-adjusting sealing structure is provided in the sealing mounting groove.

[0007] The quick-adjustment sealing structure includes a cable fixing plate and a sealing movable plate. The cable fixing plate is fixedly connected to the side of the cable through hole facing the inner wall of the meter box body. The sealing movable plate abuts against the side of the cable fixing plate facing the inner wall of the meter box body and is slidably connected to the sealing mounting groove. The end of the cable fixing plate facing the sealing movable plate is provided with a cable fixing half hole, and the side of the sealing movable plate facing the cable fixing half hole is provided with a sealing movable half hole.

[0008] In one possible implementation, the cable fixing plate has a cable fixing strip on the side facing the sealing movable plate, and the sealing movable plate has an auxiliary sealing strip on the side facing the cable fixing plate. The cable fixing strip and the auxiliary sealing strip are respectively located on both sides of the cable fixing half hole and the sealing movable half hole, parallel to the installation direction of the device.

[0009] In one possible implementation, the cable fixing plate is disposed between the cable through holes, the sealing movable plate is disposed on the side away from the cable through holes, and the sealing movable plate is provided with a worm gear transmission structure on the side facing the meter box body and parallel to the installation direction of the device for adjusting the movement of the sealing movable plate toward the cable fixing plate.

[0010] In one possible implementation, both the side of the cable fixing half-hole facing the sealing movable half-hole and the side of the sealing movable half-hole facing the cable fixing half-hole are covered with rubber sealing strips.

[0011] In one possible implementation, the cross-sections of both the cable fixing half-hole and the sealing movable half-hole are U-shaped.

[0012] In one possible implementation, each of the sealed movable half-holes facing the cable threading hole is provided with a flexible sealing block for filling the gap between the cable and the cable threading hole.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] After threading the cable through the cable threading hole and connecting it to the electrical equipment, insert the cable at the threading hole into the cable fixing half-hole of the cable fixing plate. Then, adjust the worm gear transmission structure according to the actual diameter of the cable to make the sealing movable half-hole of the sealing movable plate move closer to the cable fixing half-hole. Adjust until the sealing movable half-hole and the cable fixing half-hole are tightly fitted with the cable to complete the sealing at the cable threading hole.

[0015] Simply insert the cable through the cable threading hole into the cable fixing half-hole, then push the sealing movable plate to quickly complete the installation of the sealing structure, significantly shortening installation time and facilitating maintenance. Furthermore, by adjusting the sealing movable plate, it can accommodate cables of different diameters. Simultaneously, the cooperation between the sealing movable half-hole, the cable fixing half-hole, and the rubber sealing strip, along with the worm gear transmission structure design, ensures a tight fit against the cable, effectively reducing the possibility of insects entering the meter box and extending the equipment's service life.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1-6As shown, this embodiment proposes an easy-to-install meter box, including a meter box body 1 and a cable threading hole 2. The meter box body 1 provides an installation carrier and protective shell for the internal electrical components, and a sealed mounting groove 4 is provided on the ground-facing side of the meter box body 1. The cable threading hole 2 is located in the sealed mounting groove 4. By clearly defining the cable threading hole 2, the possibility of cables being randomly threaded and damaging the meter box body 1 is reduced, and installation space is also provided for the subsequent quick-adjustment sealing structure 5, improving the compactness of the structure.

[0028] Meanwhile, the sealing mounting groove 4 is equipped with a quick-adjustment sealing structure 5. The number of quick-adjustment sealing structures 5 can be adjusted according to actual conditions. In this embodiment, two are preferred, located on both sides of the sealing mounting groove 4 respectively. Its structure includes a cable fixing plate 51 and a sealing movable plate 52. The cable fixing plate 51 is located on the side of the cable threading hole 2 away from the ground. The sealing movable plate 52 abuts against the side of the cable fixing plate 51 away from the ground and is slidably connected to the inner wall of the sealing mounting groove 4. By placing the cable fixing plate 51 and the sealing movable plate 52 inside the housing, it can effectively protect the components from damage by the external environment. Furthermore, the sliding connection allows the sealing movable plate 52 to achieve a quick adjustment function by pushing or driving.

[0029] Meanwhile, the cable fixing plate 51 has a cable fixing half hole 511 at the end facing the sealing movable plate 52, which can initially limit the radial movement of the cable; the sealing movable plate 52 has a sealing movable half hole 521 on the side facing the cable fixing half hole 511. When the sealing movable plate 52 slides towards the cable fixing half hole 511, as the sealing movable plate 52 and the cable fixing half hole 511 gradually come into contact, a cable clamping area is formed between the sealing movable half hole 521 and the cable fixing half hole 511. By adjusting the sealing movable plate 52 according to the actual diameter of the cable, the sealing structure can be quickly installed.

[0030] In this embodiment, the cable fixing plate 51 is disposed between the cable threading holes 2, and the sealing movable plate 52 is disposed on the side away from the cable threading holes 2, so that the sealing movable plate 52 and the cable fixing plate 51 can be placed horizontally in the meter box body 1, providing installation space for the subsequent worm gear transmission structure 6.

[0031] A worm gear transmission structure 6 for adjusting the sealing movable plate 52 is provided on the side facing the meter box body 1 and parallel to the installation direction of this device. This structure has a reverse locking function, and its high transmission ratio allows for fine adjustment, reducing the possibility of cable damage due to compression by the sealing movable plate 52. The worm gear transmission structure 6 includes an adjustment knob 61, a worm 62, a worm wheel 63, and a transmission screw 64. The worm 62 is located in the sealing mounting groove 4, with one end rotatably connected to the meter box body 1 and extending outwards. The adjustment knob 61 is located on the side of the worm 62 away from the meter box body 1. The worm wheel 63 meshes with the worm 62, and a coaxially arranged transmission screw 64 is fixedly connected to the center of the worm wheel 63. The side of the transmission screw 64 away from the worm wheel 63 is helically connected to the sealing movable plate 52.

[0032] When the adjustment knob 61 is turned, the worm 62 rotates, driving the worm wheel 63 to rotate. At the same time, the transmission screw 64, located at the center of the worm wheel 63, also rotates synchronously. Since the transmission screw 64 is threadedly connected to the sealing movable plate 52, the lateral position of the sealing movable plate 52 can be adjusted by turning the adjustment knob 61.

[0033] In this embodiment, the cable fixing plate 51 has a cable fixing strip 53 on the side facing the sealing movable plate 52, which reduces the lateral displacement of the cable. Simultaneously, the sealing movable plate 52 has an auxiliary sealing strip 54 on the side facing the cable fixing plate 51, increasing the contact area with the cable and improving the sealing effectiveness. Furthermore, the cable fixing strip 53 and the auxiliary sealing strip 54 are respectively located on both sides of the cable fixing half-hole 511 and the sealing movable half-hole 521, parallel to the installation direction of the device, effectively preventing conflicts between components. While not affecting cable installation, the increased contact area effectively improves the reliability of the seal. In conjunction with the sealing movable plate 52, it can accommodate various cable diameters. When multiple cables of different specifications are simultaneously threaded, by adjusting the sealing movable plate 52, the edges of each cable will fit against the cable fixing strip 53 and the auxiliary sealing strip 54, accommodating a large number of cables of different specifications. This improves the applicability and practicality of this embodiment in complex wiring scenarios.

[0034] In this embodiment, both the side of the cable fixing half-hole 511 facing the sealing movable half-hole 521 and the side of the sealing movable half-hole 521 facing the cable fixing half-hole 511 are covered with rubber sealing strips 55. The elastic deformation of the rubber can compensate for the gap between the cable and the sealing movable half-hole 521 and the cable fixing half-hole 511. Furthermore, it can protect the outer insulation layer of the cable from contacting the rigid contact surface, improving the safety and applicability of this embodiment.

[0035] In this embodiment, both the cable fixing half-hole 511 and the sealing movable half-hole 521 have a U-shaped cross-section. The large arc area and straight sides allow for better adaptation and fit with cables of various diameters. Furthermore, the U-shaped arc transition has no sharp edges, effectively reducing the possibility of the cable's outer insulation layer being scratched. Compared to irregularly shaped half-holes, the U-shaped arc transition is easier for mass production, reducing processing time and costs.

[0036] In this embodiment, each of the sealed movable half-holes 521 facing the cable threading hole 2 is provided with a flexible sealing block 56 for filling the gap between the cable and the cable threading hole 2. It can adapt to cables of various diameters and specifications through flexible deformation. Even in irregular and imperfect matching scenarios caused by differences in cable specifications or installation deviations, it can effectively eliminate the gap between the cable and each half-hole, thereby blocking the path of mosquitoes to enter the meter box through the gap, and further improving the sealing performance and applicability of this embodiment.

[0037] The flexible sealing block 56 is preferably made of EPDM rubber, which has the advantages of excellent elasticity, good elasticity and high elastic recovery, and can fill the gap between the cable and the cable hole 2. It also has strong weather and temperature resistance, covering an extreme climate range of -45℃ to 150℃, enabling it to adapt to complex outdoor environments and has a long service life. Furthermore, it is practical and easy to maintain, with a tear strength ≥18kN / m, making it less prone to damage during installation, an elastic recovery rate exceeding 92%, and good reusability. It offers high cost-effectiveness, costing 30% less than silicone rubber, balancing performance and mass production requirements, and fully meeting the multi-dimensional sealing requirements of meter boxes.

[0038] The workflow of this embodiment is as follows:

[0039] 1. After threading the cable through the cable threading hole 2 and connecting it to the electrical equipment, insert the cable at the cable threading hole 2 into the cable fixing half hole 511 and the cable fixing strip 53 of the cable fixing plate 51 to complete the initial positioning of the cable.

[0040] 2. Rotate the adjustment knob 61. The adjustment knob 61 drives the worm 62 to rotate. The worm 62 meshes with the worm wheel 63, thereby driving the worm wheel 63 and the transmission screw 64 located at its center to rotate synchronously. The transmission screw 64 can then drive the sealing movable plate 52 to slide linearly to one side of the cable fixing plate 51.

[0041] 3. Based on the actual number and specifications of the cables, rotate the adjustment knob 61 until the rubber sealing strip 55 of the sealing movable plate 52 is in close contact with the cables. At this time, the flexible sealing block 56 located on the auxiliary sealing strip 54 also deforms, gradually filling the gap between the cables and each half hole. At this time, the sealing of the cable threading hole 2 is completed.
