[0027] 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 of 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.

[0028] Reference Figure 1-Figure 7 The embodiment provides an electrically controlled safety switch that is easy to disassemble and assemble, including a dark box mechanism 1 and a switch mechanism 2. The dark box mechanism 1 includes a mounting box 11, in which a pair of plug-in components 12 are arranged. The switch mechanism 2 includes a switch seat 21 plugged into the mounting box 11, and a panel 22 is arranged on the switch seat 21. A plug-in hole 23 that matches the plug-in component 12 is opened on the panel 22, and a card slot 24 is formed at the front end opening of the plug-in hole 23 extending to both sides. The plug-in component 12 cooperates with the plug-in hole 23 and the card slot 24 to fix the switch seat 21 in the mounting box 11.

[0029] In the utility model, the mounting box 11 of the dark box mechanism 1 is pre-installed on the oil drilling rig, and the mounting seat 21 of the switch mechanism 2 is plugged into the mounting box 11 from front to back. During the plugging process, the plug assembly 12 passes through the plug hole 23, and the panel 22 of the switch seat 21 is against the front side of the mounting box 11. The switch seat 21 is plugged and fixed to the mounting box 11 by the cooperation of the plug assembly 12, the plug hole 23 and the card slot 24, without using a plurality of bolt fasteners, so that the switch seat 21 can be disassembled and assembled conveniently and quickly, and it is further convenient to maintain and repair the electric control switch, so that the electric control switch can accurately turn on and off the power supply at all times.

[0030] Specifically, refer to Figure 4 The plug assembly 12 includes a plug plate 121, and the front ends of the plug plate 121 are slidably connected to the limit plate 124 through the installation groove 122. A spring 126 is provided between the limit plate 124 and the inner wall of the installation groove 122. The limit plate 124 can be telescopically moved by the spring 126, so that when the safety switch is installed and disassembled, the limit plate 124 is first stored in the installation groove 122 so that the plug plate 121 can smoothly pass through the plug hole 23, and then the limit plate 124 is released. Under the action of the spring 126, the limit plate 124 pops up and is stuck in the card slot 24, thereby realizing the rapid plug-in installation of the safety switch. When the switch needs to be disassembled, the limit plate 124 is pressed into the installation groove 122, and then the switch seat 21 is pulled out from the plug plate 121. It is convenient and quick, and there is no need to disassemble and assemble multiple bolt fasteners, saving time and effort.

[0031] Among them, a sliding groove 123 connected to the installation groove 122 is opened on the front side of the plug plate 121, and a pulling plate 125 is provided on the limit plate 124, which passes through the sliding groove 123 and extends to the front of the plug plate 121. The pull plate 125 can be used to conveniently pull and move the limit plate 124. During the installation and disassembly process of the switch seat 21, the limit plate 124 can be quickly pressed into the installation groove 122.

[0032] Specifically, refer to Figure 5 and Figure 6 The panel 22 is provided with a protection component 25 that matches the card slot 24. The protection component 25 includes a protection cover 251. One end of the protection cover 251 is connected to the panel 22 through a connecting strip 252. The other end of the protection cover 251 is provided with a handle 253. The protection cover 251 is connected to the panel 22 through the connecting strip 252. After the switch base 21 is installed, the protection cover 251 is buckled on the card slot 24, thereby preventing dust from accumulating in the card slot 24 and preventing damage to the plug-in component 12 in the card slot 24, thereby protecting the plug-in component 12.

[0033] It should be noted that the protective cover 251 is made of plastic or acrylic, and the connecting strip 252 is made of rubber. The protective cover made of plastic or acrylic has a certain strength and can protect the internal plug-in components. The connecting strip 252 made of rubber is flexible and can realize the opening and closing of the protective cover 251.

[0034] For details, refer to 2- Figure 3 , Figure 5 A positioning plate 13 is provided on the inner wall of the installation box 11, and a positioning groove 26 matching the positioning plate 13 is provided on the switch seat 21. The switch seat 21 is slidably plugged into the interior of the installation box 11 through the positioning groove 26 and the positioning plate 13. The positioning plate 13 and the positioning groove 26 are used to achieve a positioning and guiding function. When the switch seat 21 is plugged into the installation box 11, the positioning groove 26 of the switch seat 21 is first aligned with the positioning plate 13, thereby avoiding the switch seat 21 from being offset during plugging, and ensuring that the switch seat 21 can be stably and accurately inserted into the installation box 11.

[0035] It should be noted that there are several positioning plates 13 and they are symmetrically distributed along the vertical cross-section of the installation box 11. The outer edges of the positioning plates 13 are rounded. The design of several positioning plates 13 can ensure that the switch seat 21 can be more stable after the positioning plates 13 and the positioning grooves 26 are connected and installed. The outer side surfaces of the positioning plates 13 with rounded corners can slide more conveniently, making the plug-in installation of the switch seat 21 smoother.

[0036] The switch base 21 is plugged into the installation box 11 and the panel 22 is attached to the front side of the installation box 11. A wiring hole for wiring is provided at the rear end of the installation box 11. The gap between the panel 22 attached to the front side of the installation box 11 and the installation box 11 is small to avoid dust accumulation. The connecting wire is inserted and connected through the wiring hole to ensure that the switch base 21 can be connected to the power control line of the oil drilling rig.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
