[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment: an electric controller with a double sealed shell, including a shell body 1, the shell body 1 is the first layer of protection, and the overall device can be sealed. The top of the upper part of the shell body 1 is fixedly connected with a fixing groove 3, and the fixing groove 3 can be connected with the clamping block 9 to clamp and fix the shell body 1. The inside of the fixing groove 3 is slidably connected with a positioning block 2, and the positioning block 2 limits the clamping block 9 to slide relatively horizontally within a fixed distance. The lower part of the positioning block 2 is fixedly connected to the top of the shell body 1. The shell body 1 is protected. The positioning block 2 is held relatively fixed, and the interior of the positioning block 2 is slidably connected with a clamping block 9, which is U-shaped, and the front and rear ends slide out of the interior of the positioning block 2 and can be clamped with the fixed groove 3. Two groups of clamping blocks 9 are provided, and the two groups of clamping blocks 9 are elastically connected by a spring 10. The spring 10 squeezes the clamping blocks 9 at both ends to make their two ends slide out, and the outside of the clamping block 9 is slidably connected to the inside of the fixed groove 3. The two parts of the spring 10 are respectively fixedly connected to the sides of the two groups of clamping blocks 9, and the spring 10 can keep the two groups of clamping blocks 9 in a state of sliding out.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The rear fixed upper end of the positioning block 2 is fixedly connected with a T-block 12, and the T-block 12 can limit the connecting block 11 to slide vertically only within a fixed distance. The upper and lower ends of the T-block 12 are elastically connected to the connecting block 11 through the spring 2 13. The two ends of the connecting block 11 are L-shaped, and the lower end can slide into the upper end of the inner shell 5. In this way, the outer shell 1 and the inner shell 5 can slide at the same time, which is convenient for disassembly and increases the simplicity of operation. The right part of the connecting block 11 is slidably connected to the lower part of the T-block 12, and the connecting block 11 slides up, so that only the outer shell 1 can be disassembled. The left part of the connecting block 11 is slidably connected to the upper parts of the outer shell 1 and the inner shell 5, respectively. One end of the spring 2 13 is fixedly connected to the upper lower part of the T-block 12, and the spring 2 Pulling 13 can keep the connecting block 11 from being stuck inside the upper end of the inner shell 5. The other end of the spring two 13 is fixedly connected to the upper right end of the connecting block 11. The spring two 13 is kept in the state of pulling the connecting block 11 by the pulling force of the T-block 12. The front end of the outer shell 1 is elastically connected to the sliding plate 4 through the spring three 14. The sliding plate 4 can close the front part of the outer shell 1. By sliding the sliding plate 4, the front part of the outer shell 1 can be opened for connecting the line for use. One end of the spring three 14 is fixedly connected to the front end of the outer shell 1. The spring three 14 can squeeze the sliding plate 4 to keep it in a closed state. The other end of the spring three 14 is fixedly connected to the side of the sliding plate 4. The inner layer component is stuck inside the outer shell 1.

[0034] Reference Figure 1-Figure 3The inner layer component includes a base 6, which can support a T-bar 7 and an inner shell 5. The outside of the base 6 is slidably connected to the inside of the outer shell 1. The base 6 can support and place electronic components. The front and rear ends of the upper part of the base 6 are fixedly connected with a T-bar 7. The T-bar 7 can be clamped with the bottom of the inner shell 5 so that it can only slide horizontally relative to the base 6. The upper and lower parts of the T-bar 7 are slidably connected with the inner shell 5. The inner shell 5 can enclose the internal electronic components, and a bayonet is opened at the front to facilitate the sliding out of the circuit. The lower part of the inner shell 5 is in contact with the upper part of the base 6, and the outside of the inner shell 5 slides inside the outer shell 1. The outer shell 1 can seal and protect the inner shell 5. The upper end of the inner shell 5 is fixedly connected with a magnet 8. The magnet 8 can keep the inner shell 5 fixed and unable to slide horizontally, which can facilitate the disassembly and installation of the inner shell 5.

[0035] Working principle: when the outer shell 1 and the inner shell 5 need to be disassembled, the connecting block 11 can be slid down, and the connecting block 11 slides down to stretch the spring 2 13. When the connecting block 11 slides down into the upper end of the inner shell 5, the clamping block 9 is then squeezed toward the middle, and the clamping block 9 squeezes the spring 10. When both ends of the clamping block 9 completely slide into the positioning block 2, the positioning block 2 is then slid. The positioning block 2 drives the outer shell 1 and the T-block 12 at both ends to slide horizontally. The T-block 12 drives the connecting block 11 and the inner shell 5 to slide horizontally, and the inner shell 5 and the outer shell 1 can be slid out at the same time, and then the electronic components on the upper end of the base 6 can be maintained. After the maintenance is completed, the inner shell 5 and the outer shell 1 are slid back, and the lower part of the inner shell 5 is secured by the T-bar 7 and the base 6 are clamped to maintain a horizontal sliding state. When the positioning block 2 slides into the fixed groove 3, the clamping block 9 and the connecting block 11 are then released. At this time, the magnet 8 is attracted to keep the inner shell 5 fixed, and the spring two 13 can pull the connecting block 11 to slide out of the inner shell 5, and the spring one 10 squeezes the clamping blocks 9 at both ends to slide into the fixed groove 3 to keep them fixed. When only the outer shell 1 needs to be replaced, the clamping block 9 can be squeezed to make the clamping block 9 slide out of the fixed groove 3, and then the positioning block 2 can be slid out of the fixed groove 3 so that the outer shell 1 can slide out. When the line connection is needed, the sliding plate 4 can be slid, and the sliding plate 4 slides to both ends to squeeze the spring three 14, and the front of the outer shell 1 can be opened.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
