Description

Technical Field

[0001] The utility model relates to the technical field of charger shells, in particular to an explosion-proof charger shell. Background Art

[0002] The shell of the explosion-proof charger plays a major explosion-proof role. After the charger is overcharged, it is easy to catch fire inside. The explosion-proof charger shell can also prevent explosions after the internal fire. At the same time, the charger can also play an explosion-proof effect when used in a dangerous flammable gas or dust environment. The structure and materials of the explosion-proof charger shell meet the explosion-proof requirements, which can avoid sparks and explosion accidents, and improve operational safety and fire and explosion performance. The explosion-proof charger shell has good explosion-proof performance, which can avoid sparks and explosion accidents. The structure and materials meet the explosion-proof requirements and have high fire resistance.

[0003] For example, application number: CN202322396519.3 involves a safe explosion-proof charger shell, including a main body mechanism, a fixing mechanism and an adaptive mechanism, wherein the fixing mechanism is located at the lower end of the main body mechanism, and the adaptive mechanism is located inside the main body mechanism; the main body mechanism includes a main body shell, an outer surface of the main body shell is fixedly connected with an explosion-proof layer, an intermediate layer of the main body shell is fixedly connected with an insulating layer, an innermost layer of the main body shell is fixedly connected with a fireproof layer, a right end of the main body shell is fixedly connected with a slide groove, a middle part of the left end of the main body shell is fixedly connected with a card groove, and the four corners of the lower end of the main body shell are fixedly connected with fixing holes.

Even if an explosion occurs inside the explosion-proof charger casing 1, the pressure can be relieved, which effectively improves the safety. A heat dissipation groove 102 is opened on the side of the explosion-proof charger casing 1 through the side groove 101, and the reinforcement structure 2 made of elastic metal material is a rectangular frame structure, which uses elasticity to improve the strength of the explosion-proof charger casing 1.

[0028] In the present disclosure, Figure 4 and Figure 5As shown, a T-shaped side groove 101 is provided on both sides of the explosion-proof charger housing 1, so that the mobile component 103 can move freely inside it to adjust the height, and the bottom of each side groove 101 is provided with uniformly arranged heat dissipation grooves 102, and the interior of the heat dissipation groove 102 is connected with the interior of the explosion-proof charger housing 1, so that when the internal temperature of the explosion-proof charger housing 1 is high, the heat is dissipated through the heat dissipation groove 102; a mobile component 103 that can move up and down freely is inserted into the inside of the side groove 101, and the mobile component 103 blocks the heat dissipation groove 102 to prevent dust from entering, and can also be opened at will, so that the inside and outside of the explosion-proof charger housing 1 are connected to improve the heat dissipation effect, and the outside of the mobile component 103 is provided with an anti-slip groove, and a reinforcing component 104 is fixed at the internal angle position of the explosion-proof charger housing 1 to improve the strength of the explosion-proof charger housing 1; two inner parts 106 are fixed on both sides of the interior of the explosion-proof charger housing 1, and the inner end of the rubber stopper component 108 is a V-shaped structure.

When the electrical housing 1 is in use, if the internal temperature is high, the movable component 103 can be directly pulled up to expose the heat dissipation groove 102, so that the inside of the explosion-proof charger housing 1 is connected with the outside, thereby improving the heat dissipation effect. When an explosion occurs inside the explosion-proof charger housing 1, the reinforcing structure 2 is located inside the explosion-proof charger housing 1 to increase the strength. At the same time, the explosion generates pressure, causing the blocking component 108 to move and displace, so that the inside of the explosion-proof charger housing 1 is connected with the outside through the outer hole 105 and the inner groove 107, thereby generating a pressure relief channel, reducing the probability of explosion of the explosion-proof charger housing 1, and improving safety.
