Convenient-recovery explosion-proof electric appliance casing

Abstract

The invention discloses a convenient-recovery explosion-proof electric appliance casing. The casing includes a base, wherein an upper end of the base is symmetrically fixedly connected with frameworks, an upper casing and a lower casing are arranged between the two frameworks up and down, the two frameworks are internally symmetrically provided with mounting fast-dismounting mechanisms, and the fast-dismounting mechanisms include vertical rods fixedly connected with upper and lower inner walls of the frameworks. The casing is advantaged in that a screw is driven by a motor to rotate, a pressing block moves under the restriction of a limiting rod and a limiting hole, and thereby two fixing blocks are pressed and released to change the spacing between the two fixing blocks, so the upper casing and the lower casing are separated or closed, the structure is reasonable, and mounting and dismounting are very convenient; a plastic material becomes fluid under the action of the pure water, a positioning protrusion at a lower end of the upper casing and a positioning groove at an upper end of the lower casing form the sealing environment under the action of the plastic material, sealing property is improved, the upper and lower casings can be recycled for use, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of explosion-proof electrical appliances, in particular to an explosion-proof electrical casing that is easy to recycle. Background technique [0002] Explosion-proof electrical appliances, as the name implies, are electrical appliances that can prevent explosion accidents in places containing explosive dangerous gas mixtures. Explosion-proof electrical appliances in my country are basically divided into two categories: one is called explosion-proof electrical appliances for mines, which are mainly used in coal mines and mines where explosive gases such as gas protrude, and the other is called explosion-proof electrical appliances for factories. In all places except mines and coal mines. Such as: petroleum, chemical, textile, pharmaceutical, military and other enterprises, including gas explosion-proof and dust explosion-proof electrical appliances.

Problems solved by technology

[0003] In the process of long-term use of explosion-proof electrical appliances, it is easier to affect the internal components of explosion-proof electrical appliances due to various external factors and cause damage. However, the shell of explosion-proof electrical appliances is made of excellent material and has strong explosion-proof performance. Once the internal parts of explosion-proof electrical appliances are damaged, it will be damaged. The shells of explosion-proof electrical appliances are discarded together, resulting in a waste of resources; in addition, when the shells of explosion-proof electrical appliances are docked and installed, it is easy to have the problem of insufficient installation and sealing strength
