Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic sensors, and in particular relates to a fixed frame type magnetic switch for a cylinder. Background Art

[0002] A magnetic switch is a circuit switch device that uses magnetic field signals to control the circuit. It is also called a magnetic control switch and is mainly used to control the movement of industrial machinery. Existing magnetic switches require additional bolts or other binding structures to fix them on the cylinder body and sense signals through the magnetic ring of the cylinder.

[0003] At present, magnetic switches are used in many devices. In order to fix the magnetic proximity switch, it is necessary to manually press the magnetic proximity switch, and finally use the fixing screws to fix the magnetic proximity switch to the cylinder to complete the entire fixing operation. This fixing method is easy to cause damage to the magnetic switch during assembly and tightening, and there are certain safety hazards. Too loose assembly is also easy to cause fixation failure. At the same time, it requires too much manual operation, long assembly time, and low assembly efficiency. In addition, due to frequent fixing and disassembly operations of the switch, the switch housing is excessively worn and the switch is squeezed, resulting in the switch being unable to work normally, reducing the service life of the switch.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] See also Figures 1 to 4 A fixed frame magnetic switch for a cylinder includes a switch body 1, the switch body 1 includes a switch 11 and a shell covering the switch 11, the switch 11 and its induction circuit board are both arranged in the inner cavity of the shell, and the indicator light head is exposed through the indicator light installation position at the front end of the shell.

[0021] The housing includes a top cover 12 and a bottom cover 13 . The working surface of the top cover 12 is provided with a mounting groove 121 , and the working surface of the bottom cover 13 is provided with an inner concave arc surface 131 along the axis direction of the switch 11 .

[0022] The switch body 1 is matched with a clamping mounting seat 2, which includes a fixing block 23 and an adjusting block 24. The fixing block 23 is concavely provided with a groove-shaped structure, forming a switch fixing portion 22. The rear end surface of the fixing block 23 is matched with the adjusting block 24 to form a cylinder fixing portion 21. The switch body 1 is fixed at the switch fixing portion 22, and the cylinder fixing portion 21 is clamped with the cylinder pull rod 3.

[0023] In order to adapt to cylinders of various sizes, a first fixed adjustment mechanism 41 is provided on the front end surface of the fixed block 23, and cooperates with the switch fixing part 22 to achieve the fixation and adjustment of the switch body 1. A second fixed adjustment mechanism 42 is provided on the adjustment block 24, and cooperates with the adjustment hole provided on the rear end surface of the fixed block 23 to achieve the fixation and adjustment of the cylinder pull rod 3. The first fixed adjustment mechanism 41 and the second fixed adjustment mechanism 42 both adopt a bolt structure. Of course, other adjustment mechanisms can also be used to achieve the fixed tightness adjustment.

[0024] Since the fixing positions are mostly circular surfaces, an anti-slip structure 241 is provided on the working surface opposite to the rear end surface of the adjusting block 24 and the fixing block 23 to prevent fixation failure due to slipping and avoid equipment failure. The anti-slip structure 241 can be set to a toothed structure, and of course can also be set to an anti-slip gasket structure, which can be freely changed according to actual use requirements.

[0025] In order to effectively fix the switch body 1 in the groove structure of the switch fixing part 22, the top cover 12 is provided with a metal structure to form a strong and wear-resistant structure, which can protect the switch during installation and avoid failure caused by switch deformation. At the same time, the width of the assembly groove 121 arranged on the working surface of the top cover must match the size of the switch fixing part 22 to achieve good fixation.

[0026] The bottom cover 13 is in contact with the cylinder. To avoid wear on the surface of the cylinder, the bottom cover 13 is made of plastic, which can also better fit the surface of the cylinder. Of course, an inner concave arc surface 131 is also provided on the working surface of the bottom cover 13, and the curvature of the inner concave arc surface 131 is consistent with the curvature of the surface of the cylinder body 31, so that it can better fit the surface of the cylinder.
