Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electricity metering boxes, specifically a waterproof outdoor electricity metering box. Background Technology
[0002] Electricity metering boxes are used to install electricity metering devices, such as electricity meters and transformers, to accurately measure the electricity consumption of users. They are commonly found in the power distribution systems of residential buildings, commercial buildings, and industrial enterprises. According to the installation location, they can be divided into indoor electricity metering boxes and outdoor electricity metering boxes. Since outdoor electricity metering boxes are installed outdoors and are frequently exposed to rain, they have high requirements for their waterproof performance.
[0003] The existing outdoor power metering boxes are sealed only by a single sealing strip between the box body and the cover, and the seam between the box body and the cover is exposed on the outside, resulting in poor sealing and weak waterproofing. In heavy rain, rainwater may enter the box body along the seam, causing short circuits and other malfunctions inside the box. Utility Model Content
[0004] The purpose of this utility model is to provide a waterproof outdoor power metering box to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof outdoor power metering box, comprising a box body, a detachable cover mounted on the front of the box body, and multiple fixing posts on one side of the cover. The box body has through holes corresponding to the fixing posts, and screws are threaded to the middle of the fixing posts. A waterproof baffle is integrally formed on the edge of the cover near the box body, and a gap is formed between the waterproof baffle and the box body. A second sealing strip is installed on the inner side of the cover. A sealing groove that mates with the second sealing strip is provided on one side of the box body. A pressure frame is installed on the outer side of the box body. A first sealing strip that matches the gap is installed on one side of the pressure frame. An L-shaped fixing piece for fixing the pressure frame is provided on one side of the pressure frame.
[0006] As a preferred embodiment of this utility model, the rear side of the box is provided with a plurality of annular protrusions, and the annular protrusions and the adjacent perforations are on the same axis.
[0007] As a preferred embodiment of this utility model, one end of the L-shaped fixing piece is provided with a circular hole corresponding to the through hole.
[0008] As a preferred embodiment of this utility model, the L-shaped fixing piece has an accommodating groove adapted to the annular protrusion on the side near the box body.
[0009] Compared with the prior art, the beneficial effects of this utility model are: the sealing groove, the second sealing strip and the first sealing strip can play a double sealing role, which improves the sealing performance between the box body and the box lid. In addition, the waterproof baffle and the pressure frame can block the joint between the box body and the box lid multiple times, thereby improving the waterproof performance between the box body and the box lid and preventing external rainwater from entering the box body along the joint.

[0017] 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.
[0018] Please see Figures 1 to 6This utility model provides a technical solution: a waterproof outdoor electricity metering box, including a box body 1, a box cover 2 detachably installed on the front of the box body 1, and multiple fixing posts 10 on one side of the box cover 2. The box body 1 has through holes 13 corresponding to the fixing posts 10. A screw 7 is threaded into the middle of each fixing post 10. A waterproof baffle 5 is integrally formed on the edge of the box cover 2 near the box body 1. The waterproof baffle 5 is used to cover the joint between the box body 1 and the box cover 2, preventing rainwater from falling directly onto the joint and entering the box body 1. A gap 8 is formed between the waterproof baffle 5 and the box body 1. A second sealing strip 14 is installed on the inner side of the box cover 2. The second sealing strip 14 cooperates with the sealing groove 11 to seal the box body 1 and the box cover 2, providing a first layer of sealing. The first sealing strip 3 and the gap 8 are used to seal the waterproof baffle 5 and the box body 1. The gap 8 is sealed, providing a second layer of sealing and achieving multiple sealing effects, resulting in good waterproof performance. A sealing groove 11 is provided on one side of the box body 1 to cooperate with the second sealing strip 14. A pressure frame 6 is installed on the outside of the box body 1. The pressure frame 6 can not only press the first sealing strip 3 to improve the sealing effect of the first sealing strip 3, but also cover the gap 8, that is, block the joint between the box body 1 and the box cover 2, further improving the waterproof effect. A first sealing strip 3 that matches the gap 8 is installed on one side of the pressure frame 6. The side of the first sealing strip 3 away from the pressure frame 6 has a chamfer, making it easier to align the first sealing strip 3 with the gap 8 and insert it. The first sealing strip 3 and the second sealing strip 14 are made of rubber. An L-shaped fixing piece 4 is provided on one side of the pressure frame 6 for fixing the pressure frame 6. The L-shaped fixing piece 4 cooperates with the screw 7 to fix the pressure frame 6 to the box body 1.
[0019] The rear side of the housing 1 is provided with multiple annular protrusions 9. The annular protrusions 9 are used to improve the structural strength at the perforation 13 and prevent cracking. The annular protrusions 9 and the adjacent perforation 13 are on the same axis.
[0020] One end of the L-shaped fixing piece 4 is provided with a circular hole 12 corresponding to the through hole 13. One end of the screw 7 passes through the circular hole 12 and the through hole 13 in sequence and is threaded to the fixing post 10, thereby realizing the fixing between the box body 1, the box cover 2 and the pressure frame 6.
[0021] Among them, the L-shaped fixing piece 4 has a receiving groove 15 that matches the annular protrusion 9 on the side near the box body 1. The receiving groove 15 is used to avoid the annular protrusion 9, so that one end of the L-shaped fixing piece 4 fits the box body 1 more closely.
[0022] Specifically, during assembly, first align the fixing post 10 with the through hole 13, so that the cover 2 and the body 1 are tightly fitted together. After they are tightly fitted together, one end of the fixing post 10 will be inserted into the through hole 13. Then, take the pressure frame 6 and install it on the outside of the body 1, so that one side of the pressure frame 6 is tightly fitted to the body 1 and the cover 2. At this time, the receiving groove 15 is tightly fitted with the annular protrusion 9, and the round hole 12 is aligned with the through hole 13. The first sealing strip 3 on the pressure frame 6 will be inserted into the gap 8. Then, pass the screw 7 through the round hole 12 and the through hole 13 in sequence, and screw it into the fixing post 10. Tighten the screw 7. Under the action of the screw 7, the body 1 and the cover 2 press the second sealing strip 14 together. The pressure frame 6 presses the body 1 and the cover 2 together to cover the gap 8. At the same time, the pressure frame 6 and the cover 2 cooperate to press the first sealing strip 3 together, so as to improve the sealing effect of the first sealing strip 3 and the second sealing strip 14, and make the waterproof performance between the body 1 and the cover 2 good.
