[0002] The distribution box is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint and environmental protection. It is the control center that directs the rational distribution of electrical energy among various components in the power supply line.

[0003] For example, patent publication number CN221508765U discloses a distribution box with flexible component installation, comprising a box body, a door panel hinged to the box body, components, racks, a wiring-capable bending guide rail, and vertical frames. The racks are arranged around the inner surface of the box body back panel, and the vertical frames are mounted in pairs on two opposing racks. The ends of the bending guide rails are connected to the pair of vertical frames via a height adjustment mechanism, and the components are mounted on the bending guide rails. Although this distribution box with flexible component installation can adjust the component installation position, it can achieve flexible component installation;

[0029] In this embodiment, through the arrangement of the box body 1, the box door 2, the sliding rod 3 and the installation assembly, in actual use, a cavity with an opening on the front side is provided in the box body 1, and the box door 2 is hingedly connected to the box body 1, so that the box door 2 can open and close the cavity so as to install various components inside the box body 1; wherein, the sliding rod 3 is detachably installed in the box body 1 through the installation assembly, so that the operator can vertically install the sliding rod 3 in the box body 1.

[0030] In this embodiment, by setting the connecting block 4, the horizontal plate 5, the groove 6, the mounting plate 7, the right-angle plate 8, the card hole 9, the card block 10, the inclined surface 11 and the telescopic assembly, in actual use, the two ends of the mounting plate 7 are respectively installed between the corresponding connecting blocks 4 on the two sliding rods 3. When the circuit components are installed on the mounting plate 7, the inclined surface 11 on the right-angle plate 8 can be first brought into contact with the corresponding card block 10, and then the mounting plate 7 can be pushed to make the right-angle plate 8 snap into the groove 6. During this process, the inclined surface 11 squeezes the card block 10, causing the card block 10 to retract. As the mounting plate 7 is moved By continuing to push, the inclined surface 11 squeezes the card block 10 and retracts it into the connecting block 4 until the end face of the card block 10 contacts the right-angle plate 8, and then continues to push the mounting plate 7 until the card block 10 is aligned with the card hole 9. Under the drive of the telescopic assembly, the card block 10 can be snapped into the card hole 9. By snapping the card block 10 into the card hole 9, the fixed installation of the mounting plate 7 can be completed. After the mounting plate 7 is installed, the circuit components can be installed on the mounting plate 7. Compared with the existing embodiment, this embodiment can avoid the use of multiple screws for fixing the mounting plate 7 during installation, and the operation is more convenient and easy for users to use.

[0031] In this embodiment, due to the setting of the fixing component, since the connecting block 4 and the sliding rod 3 are slidably installed, the fixing component is used to release the fixing of the connecting block 4 on the sliding rod 3, so that the connecting block 4 can slide arbitrarily on the sliding rod 3, thereby driving the mounting plate 7 installed between the sliding rods 3 to slide up and down arbitrarily, and then adjusting the gap between adjacent mounting plates 7 according to the installation needs of circuit components.

[0032] In this embodiment, when the box body 1 is fixed, the box body 1 can be fixed to the wall by expansion bolts, and a notch 14 for wiring is provided at the bottom of the box body 1.

[0033] See also Figure 1-Figure 7 In this embodiment, the mounting assembly includes a fixing block 100 symmetrically arranged on the upper and lower inner walls of the box body 1, a T-shaped slide groove 101 is provided in the fixing block 100, and a T-shaped slide groove 101 is provided in the T-shaped slide block 102 connected to the corresponding ends of the sliding rod 3 respectively, and a first nut 103 for fixing the sliding rod 3 is threaded on the sliding rod 3.

[0034] In this embodiment, by setting the fixing block 100, T-shaped slide groove 101, T-shaped slider 102 and first nut 103, in actual use, the fixing block 100 is welded and fixed to the upper and lower inner walls of the box body 1 along the front and rear directions of the box body 1, and the T-shaped slider 102 is slidably installed in the T-shaped slide groove 101. The T-shaped sliders 102 at the upper and lower ends are respectively fixedly connected to the upper and lower ends of the sliding rod 3. When the sliding rod 3 is installed, the T-shaped slider 102 slides into the corresponding T-shaped slide groove 101. According to the size of the circuit components, the T-shaped slider 102 is pushed to slide in the T-shaped slide groove 101, so that the sliding rod 3 is in a suitable position close to the rear wall of the box body 1. After the position is adjusted, the sliding rod 3 can be limited by tightening the first nut 103 to complete the installation of the sliding rod 3.

[0035] See also Figure 1-Figure 7 In this embodiment, a mounting cavity is provided in the connecting block 4 and passes through the connecting block 4, and one end of the clamping block 10 is extended into the mounting cavity; the telescopic assembly includes a round rod 200 provided in the mounting cavity and connected to the clamping block 10, and a removable sealing plate 201 is provided at the open end of the mounting cavity away from the clamping block 10, and the end of the round rod 200 away from the clamping block 10 passes through the sealing plate 201, and a spring 202 is provided in the mounting cavity and is sleeved on the round rod 200 and used to push the clamping block 10 to be clamped into the clamping hole 9.

[0036] In this embodiment, the arrangement of the mounting cavity, the round rod 200, the sealing plate 201 and the spring 202 allows the card block 10 to be slidably installed in the mounting cavity. The sealing plate 201 is detachably connected to the open end of the mounting cavity by screws so as to install the components in the mounting cavity. The round rod 200 is fixedly connected to the card block 10, and the round rod 200 slides through the sealing plate 201. When the inclined surface 11 squeezes the card block 10, the card block 10 can be gradually retracted into the mounting cavity by compressing the spring 202. When the card block 10 is aligned with the card hole 9, the spring 202 can push the card block 10 to be clamped into the card hole 9, thereby fixing the mounting plate 7.

[0037] Specifically, in order to prevent the spring 202 from driving the card block 10 out of the installation cavity, a baffle 204 is provided at the end of the round rod 200 that passes through the sealing plate 201. The baffle 204 is attached to the sealing plate 201 to limit the card block 10 to prevent it from leaving the installation cavity.

[0038] See also Figure 1-Figure 7 In this embodiment, a pull rod 203 is provided outside the baffle 204 for disengaging the card block 10 from the card hole 9, and a fixed plate 205 is provided on one side of the pull rod 203 of the connecting block 4. The fixed plate 205 is provided with a displacement groove, and a telescopic plate 206 is provided in the displacement groove that can slide up and down and cooperate with the baffle 204 to keep the card block 10 out of the card hole 9.

[0039] Specifically, a handle 208 for pulling the telescopic plate 206 is provided on the upper end surface of the telescopic plate 206 .

[0040] In this embodiment, the arrangement of the pull rod 203, the baffle 204, the fixed plate 205, the displacement groove, the telescopic plate 206, the extrusion surface 207 and the handle 208 allows, in actual use, the pull rod 203 to be fixedly connected to the baffle 204, and the baffle 204 to be fixedly connected to the round rod 200, so that the pull rod 203 can drive the clamping block 10 to retract into the mounting cavity, thereby releasing the fixation of the mounting plate 7;

[0041] In order to keep the block 10 retracted in the installation cavity and facilitate the operator to disassemble and install the mounting plate 7 in the groove 6, the telescopic plate 206 is disengaged from the displacement groove before the pull rod 203 is pulled. At this time, the pull rod 203 is pulled to move the baffle 204 to the displacement groove. At this time, the telescopic plate 206 is inserted into the groove to block the baffle 204 to prevent it from returning to its original position under the action of the spring 202, thereby keeping the block 10 retracted in the installation cavity.

[0042] By pulling up the handle 208 , the telescopic plate 206 can be preferably disengaged from the displacement slot, so that the clamping block 10 can be reset under the action of the spring 202 .

[0043] Specifically, the telescopic plate 206 is T-shaped so that it can be inserted into the displacement slot, thereby preventing the telescopic plate 206 from falling when inserted into the displacement slot.

[0044] See also Figure 1-Figure 7 In this embodiment, the fixing assembly includes a sleeve 300 arranged on the upper end surface of the connecting block 4 and sleeved on the outside of the sliding rod 3. A plurality of deformable clamping blocks 301 are evenly distributed along the circumferential direction on the upper end surface of the sleeve 300. A second nut 302 is provided on the sleeve 300 for squeezing the clamping blocks 301 to tightly hold the sliding rod 3.

[0045] In this embodiment, by setting the sleeve 300, the clamping block 301 and the second nut 302, the sleeve 300 is fixedly connected to the connecting block 4, and the second nut 302 is threadedly connected to the sleeve 300. When the connecting block 4 is limited, the second nut 302 can be rotated, and the clamping block 301 can be squeezed by the inner ring of the second nut 302, so that the clamping block 301 can be deformed and tightly hold the sliding rod 3, thereby limiting the connecting block 4. When it is necessary to adjust the interval between the mounting plates 7, the second nut 302 can be rotated so that the second nut 302 does not squeeze the clamping block 301, and the clamping block 301 restores its deformation and does not clamp the sliding rod 3, so that the sliding connecting block 4 can arbitrarily adjust the interval between the mounting plates 7.

[0046] Among them, there is a gap between the clamping blocks 301 to facilitate the deformation of the clamping blocks 301 to clamp the sliding rod 3. At the same time, the second nut 302 has a certain length. When the second nut 302 squeezes the clamping blocks 301 to clamp the sliding rod 3, a part of the lower end of the second nut 302 can still be threadedly connected to the sleeve 300.

[0047] See also Figure 1-Figure 7 In this embodiment, heat dissipation holes 12 are provided on both sides of the box body 1, and rain shields 13 are provided at the heat dissipation holes 12.

[0048] In this embodiment, the heat dissipation holes 12 are provided so that the heat dissipation holes 12 can dissipate heat from the interior of the box body 1 , and the rain shield 13 is used to prevent rainwater from entering the interior of the box body 1 through the heat dissipation holes 12 .

[0049] Working principle: When the present invention is in use, the sliding rod 3 is first installed vertically in the box body 1 through the installation component, and then the installation plate 7 is pushed to make the inclined surface 11 squeeze the card block 10. As the installation plate 7 is continuously pushed, the inclined surface 11 squeezes the card block 10 into the connecting block 4 and retracts until the end face of the card block 10 contacts the right-angle plate 8. Then, the installation plate 7 is continued to be pushed until the card block 10 is aligned with the card hole 9. Driven by the telescopic component, the card block 10 is snapped into the card hole 9 to complete the installation of the mounting plate 7. Then, the connecting block 4 is adjusted to slide on the sliding rod 3 through the fixing component. According to the installation requirements of the circuit components, the interval between the mounting plates 7 is adjusted to a suitable distance.

[0050] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
