Description

Technical Field

[0001] This utility model relates to the field of magneto-optical switch technology, and in particular to a magneto-optical switch that is easy to install. Background Technology

[0002] Magneto-optic switches are optical switches that utilize the Faraday magneto-optical effect. By changing the applied magnetic field, the effect of the magneto-optical crystal on the polarization plane of incident polarized light is altered, thereby achieving the effect of switching optical paths. They are a common type of electronic component.

[0003] In pneumatic systems, cylinders are a common power component. In some automated control systems, it is necessary to detect the position of the cylinder for automatic control. Magneto-optic switches, as position sensors, are particularly important in the use of cylinders. In existing technology, most magneto-optic switches are fixed to the concave surface of the cylinder profile using a built-in set screw. The head of the set screw directly presses against the magneto-optic switch, and the tail of the set screw directly presses against the concave surface of the cylinder profile. During installation, the magnetic proximity switch must be manually pressed down, and then the screw is used to fix the magnetic proximity switch to the cylinder to complete the entire fixing operation. When adjusting the position of the magneto-optic switch, the fixing screw needs to be loosened before adjustment. However, frequent loosening and tightening of the bolt can easily damage the threaded hole on the magneto-optic switch, making it impossible to fix the switch. In this case, it is often necessary to replace the switch with a new one. However, the original switch's threaded hole is damaged, but its working module is still in normal working condition, which seriously increases the cost of use. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-install magneto-optical switch, which aims to optimize the traditional switch installation structure and reduce the cost of use.

[0005] To achieve the above objectives, this utility model provides an easy-to-install magneto-optical switch, including a cylinder and an installation mechanism;

[0006] The installation mechanism includes a first hook, a T-shaped pull rod, a threaded sleeve, a second hook, a threaded rod, and a switching device. The first hook is detachably connected to the pull rod of the cylinder and is engaged on one side of the cylinder. The T-shaped pull rod is threadedly connected to the first hook and is located on the first hook. The threaded sleeve is fitted on the outside of the T-shaped pull rod and can move vertically. The second hook is detachably connected to the pull rod of the cylinder and is engaged on the pull rod on the side of the cylinder away from the first hook. The threaded rod is integrally formed with the second hook and threadedly connected to the threaded sleeve, and is located on the side of the second hook closer to the threaded sleeve. The switching device is located on the side of the threaded rod closer to the cylinder barrel.

[0007] The outer side of the threaded sleeve is hexagonal prism-shaped.

[0008] The switching device includes a mounting plate and a magneto-optical switch body. The mounting plate is welded and fixed to the threaded rod and is located on the cylinder side of the threaded rod near the cylinder. The magneto-optical switch body is detachably mounted on the mounting plate and is fixed by abutting bolts provided on the mounting plate, and is located on the cylinder side of the mounting plate near the cylinder.

[0009] The threaded holes of the abutment bolts on the mounting plate are located on the upper end face of the mounting plate.

[0010] The installation mechanism further includes a stabilizing nut, which is threadedly connected to the threaded rod and abuts against the threaded sleeve.

[0011] This utility model discloses an easy-to-install magneto-optical switch. During installation, the switch device is pre-fixed on a threaded rod. Then, a second hook is engaged with a pull rod of a cylinder. A threaded sleeve is first rotated and connected to the threaded rod at the bottom of the second hook. Further, the threaded sleeve is rotated. During rotation, the first hook needs to be aligned with the pull rod on the cylinder. When the first hook is engaged with the pull rod of the cylinder, the disc of the T-shaped pull rod abuts against the limiting part of the threaded sleeve, thereby stably pulling the first and second hooks onto the pull rod of the cylinder. Then, the switch device can perform position detection. When adjusting the position of the switch device, simply loosen the threaded sleeve so that the first and second hooks can slide but not disengage from the pull rod of the cylinder. Then, it can be pulled directly to realize the position adjustment of the switch device. This application will not damage the switch or cause it to become unusable during switch position adjustment, thus enabling replacement only when the switch is damaged. This optimizes the traditional switch installation structure and helps reduce the cost of use. Attached Figure Description

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of a magneto-optical switch that is easy to install. Figure 2 This is a cross-sectional view of the threaded sleeve 104. This utility model provides an easy-to-install magneto-optical switch: it includes a cylinder 101 and a mounting mechanism. The mounting mechanism includes a first hook 102, a T-shaped pull rod 103, a threaded sleeve 104, a second hook 105, a threaded rod 106, and a switching device. The switching device includes a mounting plate 107 and a magneto-optical switch body 108. The aforementioned solution optimizes the traditional switch installation structure and helps reduce usage costs. It is understood that the aforementioned solution can reduce usage costs.

[0021] In this embodiment, a threaded hole is provided on the front end face of the cylinder head of the cylinder 101 for easy fixing.

[0022] The first hook 102 is detachably connected to the pull rod of the cylinder 101 and is snapped onto one side of the cylinder 101. The T-shaped pull rod 103 is threadedly connected to the first hook 102 and is located on the first hook 102. The threaded sleeve 104 is fitted on the outside of the T-shaped pull rod 103 and can move vertically. The second hook 105 is detachably connected to the pull rod of the cylinder 101 and is snapped onto the pull rod on the side of the cylinder 101 away from the first hook 102. The threaded rod 106 is integrally formed with the second hook 105 and is threadedly connected to the threaded sleeve 104, and is located on the side of the second hook 105 near the threaded sleeve 104. The switching device is located on the side of the threaded rod 106 near the cylinder barrel of the cylinder 101. Both the first hook 102 and the second hook 105 have semicircular portions for easy attachment to the circular pull rod of the cylinder 101. Each of the semicircular portions of the first hook 102 and the second hook 105 has a through-threaded hole and a bolt. After installation, the bolt can be rotated to abut against the surface of the pull rod of the cylinder 101, further improving stability. The rectangular end of the first hook 102 has a through-threaded hole for easy connection to the external threaded end of the bottom of the T-shaped pull rod 103. The threaded sleeve 104 has a U-shaped cavity that is not through-hole. A through hole is opened on the limiting plate of the U-shaped cavity to allow the T-shaped pull rod 103 to pass through. The inner cavity of the threaded sleeve 104 is a threaded cavity for easy connection to the threaded rod 106. The optical axis end of the threaded rod 106 is integrally formed with the second hook 105. The switching device is located on the optical axis portion of the threaded rod 106.

[0023] Secondly, the outer side of the threaded sleeve 104 is hexagonal prism. This structural design makes it easier for the threaded sleeve 104 to be rotated using a wrench.

[0024] Then, the mounting plate 107 is welded and fixed to the threaded rod 106, and is located on the side of the threaded rod 106 near the cylinder barrel of the cylinder 101; the magneto-optical switch body 108 is detachably mounted on the mounting plate 107 and fixed by abutment bolts provided on the mounting plate 107, and is located on the side of the mounting plate 107 near the cylinder barrel of the cylinder 101. A through hole is provided on the rear side of the mounting plate 107, through which the threaded rod 106 passes. The mounting plate 107 is welded to the optical axis of the threaded rod 106. A mounting hole is provided on the end of the mounting plate 107 near the cylinder barrel of the cylinder 101. A mating groove is provided on the side of the mounting hole to communicate with it. The mating groove will not cause the magneto-optical switch body 108 to slide out, but it can facilitate the magneto-optical switch body 108 to approach the cylinder barrel surface of the cylinder 101. Abutment bolts are provided on the mounting plate 107 to abut against the magneto-optical switch body 108 for fixed positioning.

[0025] Finally, the threaded holes of the abutment bolts on the mounting plate 107 are located on the upper end face of the mounting plate 107.

[0026] When using this utility model to optimize the traditional switch installation structure and reduce usage costs, during the installation of the magneto-optical switch body 108, the magneto-optical switch body 108 is first fixed to the mounting plate 107. The mounting plate 107 is directly welded and fixed during the machining of the threaded rod 106. Then, the second hook 105 is snapped onto a pull rod of the cylinder 101, and the threaded sleeve 104 is first rotated and connected to the threaded rod 106 at the bottom of the second hook 105. Further, the threaded sleeve 104 is rotated to move closer to the second hook 105. During rotation, the first hook 102 needs to be aligned with the pull rod on the cylinder 101. When the first hook 102 is just snapped onto the pull rod of the cylinder 101 and tightly abuts, this... When the disc of the T-shaped pull rod 103 abuts against the limiting part of the threaded sleeve 104, the first hook 102 and the second hook 105 are stably pulled onto the pull rod of the cylinder 101. Then, the switch device can perform position detection. When the switch device is adjusted, the threaded sleeve 104 is loosened so that the first hook 102 and the second hook 105 can slide but not disengage from the pull rod of the cylinder 101. Then, the sliding can be pulled directly to realize the position adjustment of the switch device. After adjustment, the threaded sleeve 104 is tightened. When the switch position is adjusted, this application will not damage the switch or cause the adjustment to be scrapped. Thus, it can realize that only the switch needs to be replaced when it is damaged, thereby optimizing the traditional switch installation structure and reducing the cost of use.

[0027] Example 2:

[0028] like Figure 3 and Figure 4 As shown, where Figure 3 This is a schematic diagram of the overall structure of a magneto-optical switch that is easy to install. Figure 4 This is a schematic diagram of the setting position of the stabilizing nut 201. Based on the first embodiment, this utility model provides a magneto-optical switch that is easy to install. The installation mechanism also includes a stabilizing nut 201, which is threadedly connected to the threaded rod 106 and abuts against the threaded sleeve 104.

[0029] In this embodiment, by setting the stabilizing nut 201, the stability of the threaded sleeve 104 and the threaded rod 106 after connection can be improved, which makes it easier to ensure the stability of the first hook 102 and the second hook 105, and avoid the displacement of the magneto-optical switch body 108 caused by loosening. When the threaded sleeve 104 is loosened, the stabilizing nut 201 needs to be loosened in advance.
