Description

Technical Field

[0001] The utility model relates to the technical field of magnetic flux switches, in particular to a magnetic flux switch which is easy to assemble and disassemble. Background Art

[0002] A flux switch, also known as an electromagnetic switch, is, as the name suggests, a switch controlled by an electromagnet—a combination of an electromagnet and a switch. When the electromagnet coil is energized, it generates electromagnetic attraction, and the movable core pushes or pulls the switch contacts to close, thereby connecting the controlled circuit. Electromagnetic switches are widely used across various industries, with contactors being the most common in the industrial field. The electromagnetic switch is the control switch on the starter motor and one of the three main components of the starter. Its operating principle is that when the coil is energized, it generates electromagnetic attraction, which moves the movable core. This, in turn, pulls the transmission meshing mechanism forward, causing the starter pinion to mesh with the engine flywheel ring gear. It also pushes the switch contacts to close, energizing the DC motor and starting the engine.

[0003] Today's flux switches can basically meet people's needs, but there are still some problems. The specific problems are as follows:

[0004] 1. The problem that the magnetic flux switch is difficult to disassemble and assemble. The magnetic flux switch may need to be disassembled and assembled for use. The switch is difficult to use in different situations. When the switch is damaged, it also needs to be replaced.

[0005] 2. It is difficult for the magnetic flux switch to protect the button. The button can control the switch, but it is easy to be accidentally touched, which affects the operation of the device. Therefore, the button needs to be protected. Utility Model Content

[0006] The utility model aims to provide a magnetic flux switch which is easy to assemble and disassemble, so as to solve the defects of the existing magnetic flux switch that it is difficult to assemble and disassemble the switch and it is difficult to protect the button.

[0007] In order to solve the above technical problems, the present utility model provides the following technical solutions: a magnetic flux switch that is easy to assemble and disassemble, comprising a main body structure;

[0009] The disassembly and assembly structure includes a mounting plate, a buckle, a spring, a mounting block and a rubber pad. The mounting block is mounted on the top of the housing. The inner side of the mounting block is movably connected to the rubber pad. Mounting plates are provided on both sides of the mounting block. The top of the mounting plate is penetrated by a buckle, and a spring is installed on one side of the buckle.

[0010] A button is installed on the top of the shell, a protective structure is installed on the top of the button, a protection circuit is installed inside the shell, a reed switch is installed on the bottom of the protection circuit, a connecting block is installed on one side of the shell, and a wire is installed on one side of the connecting block.

The baffle can be made of elastic steel material, and an inclined surface is provided on one side of the positioning block on the baffle. When the wire is inserted into the connecting block, the inclined surface will drive the positioning block to move outward, and then due to the elasticity of the baffle, the positioning block will be stuck in the groove on the connecting block. The positioning block can fix the wire inside the connecting block to prevent the wire from falling off.

[0012] Furthermore, the spring is in a spiral shape, the spring and the buckle form an elastic connection, and the spring is elastic.

[0013] Furthermore, a card slot is provided inside the mounting block, and a card block is provided at the bottom end of the shell. The mounting block and the shell form a card-fitting structure, and the card-fitting structure allows the shell to be replaced.

[0014] Furthermore, the top and bottom ends of the wire are both equipped with positioning structures, and the positioning structure includes a baffle, a positioning block and a mounting screw. The baffle is installed at the top and bottom ends of the wire, and the top of the baffle is equipped with a mounting screw. The card block on one side of the wire can be inserted into the inside of the connecting block. The baffle can be made of elastic steel material, and the positioning block will be stuck into the groove on the connecting block. The positioning block can fix the wire inside the connecting block to prevent the wire from falling off.

[0015] Furthermore, a positioning block is installed at the bottom end of the baffle, and the positioning blocks are symmetrically distributed about the central axis of the wire. The positioning block will be stuck into the groove on the connecting block, and the positioning block can fix the wire inside the connecting block.

[0016] Furthermore, external threads are evenly provided on the outer wall of the mounting screw, and internal threads that cooperate with the external threads are evenly provided on the inner wall of the baffle.

A protective plate is installed on one side of the connecting rod. The protective plate can cover the surface of the button. The protective plate can protect the button to prevent the button from being accidentally touched.

[0018] The magnetic flux switch which is easy to assemble and disassemble provided by the utility model has the advantages that: a mounting block is installed on the top of the shell, and the mounting block and the shell form a snap-fit structure, so the shell can be assemble and disassembled. After the shell is inserted into the mounting block, the rubber pad inside the mounting block is elastic, and the rubber pad can prevent the shell from being damaged and can also make the mounting block more stable. The buckle is connected to the mounting plate through a spring, and the spring is elastic. The elasticity of the spring will drive the buckle to be inserted into the shell, fix the shell, and make the shell more stable. When the shell needs to be disassembled, the shell can be disassembled by pulling open the buckle, thereby achieving the purpose of facilitating the disassembly and assembly of the magnetic flux switch.

[0019] By installing a fixing plate on the top of the shell, the rotation of the rotating shaft inside the fixing plate can drive the connecting rod to rotate, and the rotation of the connecting rod can drive the protective plate to rotate. The protective plate can cover the surface of the button. The protective plate can protect the button to prevent the button from being accidentally touched. When the button needs to be used, the protective plate is rotated so that the protective plate no longer covers the surface of the button, and the button can be used, thereby achieving the purpose of the magnetic flux switch to facilitate protection of the button.
