Description

Technical Field

[0001] This utility model relates to the field of power technology, specifically to an electric meter box with a sealing device. Background Technology

[0002] Sealing the inlet and outlet ports of the meter box is a crucial step in ensuring electrical safety and equipment protection. Its main purpose is to prevent dust, moisture, and small animals (such as rats and insects) from entering the meter box, thus avoiding short circuits, leakage, and other malfunctions. It also serves a degree of anti-theft and aesthetic purposes. Current sealing methods use silicone sealing rings. However, this structure, because the silicone sealing ring lacks supporting installation, is suitable only for circular holes where cables contact the box. The silicone sealing ring is prone to detachment and aging, leading to a loss of sealing performance over time. Utility Model Content

[0016] The technical solution of this utility model has the following advantages:

[0017] 1. This utility model provides an electric meter box with a sealing device. First, the fixing component forms a protective sealing gasket, protecting the outer wall of the casing. Second, the sealing assembly forms a sealed cable. When the fastener is tightened, the upper gasket compresses the sealing component, causing it to deform and thus securing the cable, improving the sealing effect. Furthermore, the fixing between the sealing assembly and the fixing component creates a modular fixing effect, making assembly more convenient. This structure ensures the protection level, prevents the sealing gasket from falling off, and improves the fixing strength and service life.

[0018] 2. The meter box with a sealing device provided by this utility model adopts the combination of two parts, which makes the installation process more convenient. In addition, the fixing part can also be a single integral structure.

[0019] 3. The meter box with sealing device provided by this utility model has a first annular groove that creates an elastic effect, causing the sealing element to deform during compression, thereby achieving a better fit with the cable.

[0020] 4. The meter box with sealing device provided by this utility model also achieves an elastic effect with the setting of the second annular groove, so that the sealing element deforms during the compression process, and better achieves the cooperation effect with the cable.

[0021] 5. The meter box with a sealing device provided by this utility model has a gap that allows the seal to be opened, forming a side opening that can wrap the cable. In other words, when the cable is already connected and fixed to the housing, the sealing component and the cable can be fitted together by a post-installation method.

[0022] 6. The present invention provides an electric meter box with a sealing device, wherein the groove, the first protrusion, and the second protrusion cooperate with each other to achieve the effect of positioning and fixing, while increasing the contact area between the sealing element and the first gasket and the second gasket. When the fastener moves, the cooperation effect is better achieved, and the overall sealing protection level is improved.

[0037] Example 1

[0038] This embodiment provides an electric meter box with a sealing device, as shown in the attached document. Figures 1-5 As shown, it includes:

[0039] The housing 11 has a first through hole 111, and the number of the first through holes 111 can be adjusted according to actual needs.

[0040] The sealing gasket 12 has a second through hole 121. The diameter of the second through hole 121 is equal to the diameter of the first through hole 111, or the diameter of the second through hole 121 is smaller than the diameter of the first through hole 111. Those skilled in the art can adjust it according to actual needs.

[0041] The fastener 13 has a third through hole 131. The sealing gasket 12 is located between the housing 11 and the fastener 13. The first through hole 111, the second through hole 121, and the third through hole 131 are connected. The diameter of the third through hole 131 is smaller than the diameter of the first through hole 111 and the diameter of the second through hole 121. Bolts pass through the fastener 13 and the sealing gasket 12 to connect and fix the fastener to the housing 11. The side wall of the housing 11 has screw holes. The bolts cooperate with the screw holes for fixing. Bolts can also pass through the housing 11 to cooperate with nuts to achieve the fixing effect.

[0042] The sealing assembly includes an upper gasket 14, a seal 15, a lower gasket 16, and a fastener 17. The seal 15 is located between the upper gasket 14 and the lower gasket 16. The upper gasket 14 is positioned above the seal 15, meaning its top surface abuts against the seal 15. The lower gasket 16 is positioned below the seal 15, meaning its bottom surface abuts against the seal 15. The fastener 17 passes through the upper gasket 14, the seal 15, and the lower gasket 16 and is connected and fixed to a fixing member 13. The fixing member 13 can have a screw hole, with the fastener 17 engaging with the screw hole for fixation. Alternatively, the fastener 17 can pass through the fixing member 13 and engage with a nut to achieve a secure hold. The seal 15 has a fourth through hole 155, the diameter of which can be equal to the diameter of the third through hole 131. The first through hole 111, the second through hole 121, the third through hole 131, and the fourth through hole 155 are interconnected and coaxial, meaning their central axes are coaxial. A cable passes through the fourth through hole 155, the third through hole 131, the second through hole 121, and the first through hole 111 into the housing 11. One end of the cable is electrically connected to an external circuit, and the other end passes into the housing 11 and forms an electrical connection with the circuit inside the housing 11, thus creating overall electrical connectivity.

[0043] Firstly, the fastener 13 forms a protective fixing effect for the sealing gasket 12, thus protecting the outer wall of the housing 11. Secondly, the sealing assembly forms a sealed fixing for the cable. When the fastener 17 is tightened, the upper gasket 14 compresses the sealing element 15, causing the sealing element 15 to deform and thus tightening the cable, improving the cable's sealing effect. Furthermore, the fixing between the sealing assembly and the fastener 13 forms a modular fixing effect, making assembly more convenient. This structure ensures the level of protection, and the sealing gasket 12 will not fall off, improving the fixing strength and service life.

[0044] Specifically, as shown in the attached document Figures 2-5 As shown, the fastener 13 includes a first component 132 and a second component 133, which are joined together to form a third through hole 131. The use of two components makes installation more convenient. In this embodiment, the first component 132 and the second component 133 are symmetrically arranged and have the same structure. They are joined together to form the third through hole 131, which is equivalent to a side-mounting method. If the meter box and cables are already fixed, side-mounting can be used, allowing the third through hole 131 to cooperate with the cables, forming a sealing gasket 12 and a fixing effect on the sealing assembly. Alternatively, the fastener 13 can also be a single integral structure.

[0045] Specifically, as shown in the attached document Figures 2-5 As shown, the first component 132 and the second component 133 are made of iron. Alternatively, the first component 132 and the second component 133 are made of stainless steel. The materials of the first component 132 and the second component 133 can be adjusted according to actual needs. The first component 132 and the second component 133 have sufficient strength to increase the strength of the sealing gasket 12.

[0046] Specifically, as shown in the attached document Figures 2-5 As shown, the cross-sectional area of ​​the fastener 13 is equal to the cross-sectional area of ​​the sealing gasket 12. Alternatively, the cross-sectional area of ​​the fastener 13 is larger than the cross-sectional area of ​​the sealing gasket 12. Alternatively, the cross-sectional area of ​​the fastener 13 is smaller than the cross-sectional area of ​​the sealing gasket 12. Those skilled in the art can adjust this according to actual needs.

[0047] Specifically, as shown in the attached document Figures 2-5 As shown, the outer wall of the seal 15 is provided with a first annular groove 151. The first annular groove 151 provides an elastic effect, allowing the seal 15 to deform under pressure, thus achieving a better fit with the cable. Here, the first annular groove 151 is recessed.

[0048] Specifically, as shown in the attached document Figures 2-5As shown, the inner wall of the seal 15 is provided with a second annular groove 152. The second annular groove 152 also achieves an elastic effect, allowing the seal 15 to deform under pressure, thus better achieving the fit with the cable. Here, the second annular groove 152 is convex.

[0049] Specifically, as shown in the attached document Figures 2-5 As shown, the seal 15 has a slit 153 that extends through the side wall of the seal 15 along its axial direction. The slit 153 allows the seal 15 to be opened, forming a side opening that can enclose a cable. This means that once the cable is already connected and fixed to the housing 11, a post-installation method can be used to form a connection between the sealing component and the cable.

[0050] Specifically, as shown in the attached document Figures 2-5 As shown, the upper end of the seal 15 has a groove 154. The upper gasket 14 includes a first gasket 141 and a second gasket 142. The first gasket 141 has a first protrusion 1411, and the second gasket 142 has a second protrusion 1421. The first protrusion 1411 extends into the groove 154. Alternatively, the second protrusion 1421 extends into the groove 154. Or, both the first protrusion 1411 and the second protrusion 1421 extend into the groove 154. The groove 154, the first protrusion 1411, and the second protrusion 1421 cooperate with each other to achieve the effect of positioning and fixing, while increasing the contact area between the seal 15 and the first gasket 141 and the second gasket 142. When the fastener 17 moves, the cooperation effect is better achieved, and the overall sealing protection level is improved. There can be multiple grooves 154. The grooves 154 can be provided on the inner wall of the seal 15 or on the outer wall of the seal 15. All grooves 154 open upwards. Those skilled in the art can adjust them according to actual needs.

[0051] Specifically, as shown in the attached document Figures 2-5 As shown, one of the first gasket 141 and the second gasket 142 is provided with a first positioning post 143, and the other of the first gasket 141 and the second gasket 142 is provided with a first positioning hole 144 that mates with the first positioning post 143. The first positioning post 143 and the first positioning hole 144 cooperate to achieve the positioning and fixing effect of the first gasket 141 and the second gasket 142, which facilitates the fit between the first gasket 141, the second gasket 142 and the seal 15. When the first gasket 141 is provided with the first positioning post 143, the second gasket 142 is provided with the first positioning hole 144; conversely, the first gasket 141 is provided with the first positioning hole 144, and the second gasket 142 is provided with the first positioning post 143. Here, there is a gap at the connection between the first gasket 141 and the second gasket 142.

[0052] Specifically, as shown in the attached document Figures 2-5As shown, the lower gasket 16 includes a third gasket 161 and a fourth gasket 162. One of the third gaskets 161 and 162 is provided with a second positioning post 163, and the other is provided with a second positioning hole 164 that mates with the second positioning post 163. The cooperation between the second positioning post 163 and the second positioning hole 164 achieves the positioning and fixing effect of the third gasket 161 and 162, facilitating the fit between the third gasket 161, 162, and the seal 15. A gap is provided at the connection between the third gasket 161 and 162.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
