[0030] Example 1

[0031] Reference Figure 1 and Figures 3-7 This is the first embodiment of the present invention. This embodiment provides an explosion-proof switch controller that is easy to install. The explosion-proof switch controller includes a main body component 100 and a mounting component 200, which cooperate with each other to facilitate the installation and disassembly of the device.

[0032] Specifically, the main component 100 includes a controller body 101, a base 102, and a carrier 103. The base 102 is fixed to the bottom of the controller body 101, and the carrier 103 is movably connected to the bottom of the base 102.

[0033] The controller body 101 is cylindrical, and the carrier 103 is rectangular. The carrier 103 is fixed to the base 102, thereby fixing the controller body 101 and the carrier 103. This is existing technology and will not be described in detail.

[0034] Specifically, the mounting component 200 is located at the bottom of the base 102 and includes a fixing post 201, a snap-fit ​​component 202, a reset component 203, a disassembly component 204, and a limiting component 205. The fixing post 201 is fixed to the bottom of the base 102, the snap-fit ​​component 202 is located inside the carrier 103, the reset component 203 is located inside the carrier 103, the disassembly component 204 is located on one side of the carrier 103, and the limiting component 205 is located on one side of the carrier 103.

[0035] The fixing post 201 is fixed to the carrier 103 by engaging with the snap-fit ​​part 202, thereby fixing the base 102 to the carrier 103. The reset part 203 and the disassembly part 204 facilitate the disassembly of the controller body 101. The limiting part 205 allows the angle of the controller body 101 to be adjusted.

[0036] Example 2

[0037] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the snap-fit ​​component 202 includes a snap-fit ​​block 202a and a first spring 202b. The snap-fit ​​block 202a is movable within the carrier 103, and one end of the snap-fit ​​block 202a is movable outside the fixing post 201. A snap-fit ​​groove V is provided on the outside of the fixing post 201, and one end of the snap-fit ​​block 202a is movable within the snap-fit ​​groove V. The two ends of the first spring 202b are fixed to the carrier 103 and the snap-fit ​​block 202a, respectively.

[0039] There are two snap-fit ​​blocks 202a and two first springs 202b. The snap-fit ​​block 202a is a right trapezoid. The right-angled surface of the snap-fit ​​block 202a is snapped and fixed with the snap-fit ​​groove V, thereby completing the snap-fit ​​fixing of the fixed post 201.

[0040] Specifically, the snap-fit ​​component 202 also includes a connecting rod 202c, which is movable within the carrier 103, and the end of the connecting rod 202c is fixed to one side of the snap-fit ​​block 202a.

[0041] There are two connecting rods 202c. The connecting rods 202c are L-shaped and have beveled ends. The connecting rods 202c drive the snap-fit ​​block 202a, which facilitates the control of the snap-fit ​​block 202a and thus facilitates the disassembly of the controller body 101.

[0042] Specifically, the reset component 203 includes a circular plate 203a and a second spring 203b. The circular plate 203a is movable within the carrier 103. A circular groove W is provided inside the carrier 103. The circular plate 203a is movable within the circular groove W. The two ends of the second spring 203b are fixed to the circular plate 203a and the inner wall of the circular groove W, respectively.

[0043] The circular plate 203a moves into the circular groove W under the pressure of the fixed column 201. The second spring 203b deforms under the pressure of the circular plate 203a. During disassembly, the reaction force of the second spring 203b on the circular plate 203a facilitates the disassembly of the controller body 101.

[0044] Specifically, the disassembly component 204 includes a push block 204a, a baffle 204b, and a third spring 204c. The push block 204a is movable within the carrier 103, the baffle 204b is fixed to one side of the push block 204a, and the two ends of the third spring 204c are fixed to the baffle 204b and the carrier 103, respectively.

[0045] The push block 204a is an isosceles trapezoid, the baffle 204b is rectangular, and there are two third springs 204c. The inclined surfaces on both sides of the push block 204a are in contact with the inclined surfaces at the ends of the connecting rods 202c. When the push block 204a is pulled, the inclined surfaces on both sides of the push block 204a exert pressure on the inclined surfaces of the connecting rods 202c on both sides. The connecting rods 202c on both sides are compressed and move in the opposite direction. The connecting rods 202c on both sides drive the locking blocks 202a on both sides to move outward from the locking groove V, thereby facilitating the disassembly of the controller body 101.

[0046] Specifically, the disassembly component 204 also includes a connecting block 204d, one end of which is fixed to one side of the push block 204a.

[0047] Example 3

[0048] Reference Figure 4 and Figure 6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0049] Specifically, the disassembly component 204 also includes a first handle 204e, the first handle 204e and the end of the connecting block 204d are fixed to one side of the carrier 103.

[0050] By setting the connecting block 204d, the control of the push block 204a is facilitated. When disassembling, the first handle 204e is pulled, the first handle 204e drives the connecting block 204d to move, and the connecting block 204d drives the push block 204a to move, so that the push block 204a can be easily controlled, thereby facilitating the disassembly of the controller body 101.

[0051] Specifically, the limiting member 205 includes a limiting rod 205a, which is movable within the carrier 103, and the end of the limiting rod 205a is movable outside the fixing post 201. A limiting groove Z is provided on the outside of the fixing post 201, and the end of the limiting rod 205a is movable within the limiting groove Z.

[0052] The limiting rod 205a is rectangular, and multiple limiting grooves Z are evenly distributed on the outside of the fixed column 201. The end of the limiting rod 205a is beveled, and a slot is provided at the end of the limiting rod 205a. The slot at the end of the limiting rod 205a engages with the limiting groove Z, thereby preventing the fixed column 201 from rotating arbitrarily. This allows the device to rotate while maintaining good stability.

[0053] Specifically, the limiting component 205 also includes a fourth spring 205b, the two ends of which are fixed to the limiting rod 205a and the inner wall of the limiting groove Z, respectively.

[0054] The fixed post 201 presses against the inclined surface of the limiting rod 205a, causing the limiting rod 205a to move outward from the limiting groove Z. The fourth spring 205b is deformed by the pressure until the fixed post 201 is locked in place. Then, the reaction force of the fourth spring 205b pushes the limiting rod 205a to move back to its original position, and the limiting rod 205a is locked into the limiting groove Z.

[0055] Specifically, the limiting component 205 also includes a rectangular block 205c and a second handle 205d. One end of the rectangular block 205c is fixed to one side of the limiting rod 205a, and the ends of the second handle 205d and the rectangular block 205c are fixed to one side of the carrier 103.

[0056] Pulling the second handle 205d causes the rectangular block 205c to move, which in turn moves the limiting rod 205a outward from the limiting groove Z. The fourth spring 205b is compressed and deformed, and the controller body 101 is rotated to adjust its angle until the angle is appropriate. Then, releasing the second handle 205d causes the reaction force of the fourth spring 205b to push the limiting rod 205a to move back to its original position. The limiting rod 205a engages with the limiting groove Z to limit the position, thus completing the adjustment of the angle of the controller body 101.

[0057] During use and installation, first push the controller body 101 towards the carrier 103. The fixing post 201 moves into the circular groove W, and the fixing post 201 presses against the inclined surface of the locking block 202a. The first spring 202b deforms under the pressure, and the circular plate 203a moves into the circular groove W under the pressure of the fixing post 201. The second spring 203b deforms under the pressure of the circular plate 203a until the reaction force of the first spring 202b pushes the locking block 202a to move and reset. The right-angled surface of the locking block 202a engages with the locking groove V, thus fixing the controller body 101. Pull the second handle 205d, which moves the rectangular block 205c. The rectangular block 205c moves the limiting rod 205a outward from the limiting groove Z, and the fourth spring 205b deforms under the pressure. Rotate the controller body 101 to adjust its angle until the angle is suitable. Then release. When the second handle 205d is opened, the reaction force of the fourth spring 205b pushes the limit rod 205a to move and reset. The limit rod 205a engages with the limit groove Z, thus completing the adjustment of the angle of the controller body 101. During disassembly, the first handle 204e is pulled first. The first handle 204e drives the connecting block 204d to move. The connecting block 204d drives the push block 204a to move. The inclined surfaces on both sides of the push block 204a press against the inclined surfaces of the connecting rods 202c on both sides. The connecting rods 202c on both sides move in the opposite direction due to the pressure. The connecting rods 202c on both sides drive the locking blocks 202a on both sides to move outward from the locking groove V. The first spring 202b is deformed due to the pressure until the locking block 202a is completely separated from the locking groove V. The reaction force of the second spring 203b pushes the circular plate 203a to move and reset. The circular plate 203a pushes the fixing post 201 out of the circular groove W, thus completing the disassembly of the controller body 101.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
