[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] Embodiment 1, refer to Figures 1 to 5 A controllable temperature explosion-proof electric heater, including shell 1, shell 1 is connected with terminal box 2 through flange, terminal box 2 is rotatably connected with rotating disc 3, rotating disc 3 is provided with clamping hole 4, rotating disc 3 is rotatably connected with multiple connecting rods 5, terminal box 2 is rotatably connected with multiple swing rods 6, multiple swing rods 6 are all provided with sliding groove 7, multiple connecting rods 5 are all installed with sliding block 8, multiple sliding blocks 8 are slidably connected with corresponding sliding grooves 7, rotating rotating disc 3 and make connecting rod 5 on rotating disc 3 slide in sliding groove 7 on swing rod 6, and make one end of connecting rod 5 against sliding groove 7 separate swing rod 6 from cover 9, can separate cover 9 from terminal box 2 through handle 12, multiple swing rods 6 are all threadedly connected with bolt 11, terminal box 2 is movably connected with cover 9, cover 9 is provided with multiple threaded holes 10, the inner wall of shell 1 is made of explosion-proof material, the material is ceramic material, the overall process is that when cover 9 on terminal box 2 is disassembled, multiple bolts 11 are loosened first, so that bolt 11 is separated from threaded hole 10 on cover 9, and then the specified tool is clamped in clamping hole 4 on rotating disc 3, then rotating rotating disc 3 and make connecting rod 5 on rotating disc 3 slide in sliding groove 7 on swing rod 6, and make one end of connecting rod 5 against sliding groove 7 separate swing rod 6 from cover 9, and separate cover 9 from terminal box 2 through handle 12, and because bolt 11 is not separated from swing rod 6, bolt 11 can be prevented from being lost due to being placed in other places, and similarly during installation, rotating rotating disc 3 can drive all bolts 11 on swing rod 6 to align with corresponding threaded holes 10 on cover 9, so that bolt 11 can be aligned and screwed one by one, and the physical strength and time of operating personnel can be saved.

[0023] In the embodiment, multiple lifting rings 18 are rotatably connected to the shell 1. When not in use, the lifting rings 18 can be hung down to avoid scratching. Two handles 12 are installed on the cover 9 to facilitate the removal of the cover 9 from the terminal box 2. Multiple heating pipes 13 are installed in the shell 1.
