Description

Technical Field

[0001] This utility model relates to the field of magnetic induction switch technology, and in particular to a strap-type magnetic induction switch. Background Technology

[0002] A magnetic induction switch is an electronic component that uses changes in magnetic fields to control the on / off state of a circuit. It consists of a sensing head and a switching circuit. When a magnetic object approaches the sensing head, its internal magnetic field changes, triggering the switch to operate. It is widely used in industrial automation, security systems, automotive electronics, and other fields to achieve functions such as position detection, counting, and limit switching, and is convenient and reliable.

[0003] A Chinese patent with publication number CN218123302U discloses a strap-type magnetic induction switch. The key technical features are: a switch body with an auxiliary mounting mechanism that mates with it; the auxiliary mounting mechanism includes a fixing strap matching the shape of a cylinder and a locking head; a fixing part is provided on the switch housing, and the auxiliary mounting mechanism connects to the switch housing via this fixing part, enabling simple and convenient fixing of the switch to the cylinder; and without increasing structural complexity, two fixing parts are provided to achieve fixing in two directions, making installation more flexible and maximizing switch performance; a buffer structure is provided at the second fixing part to prevent the vibration of the cylinder during operation from affecting the switch's working accuracy, and also to increase the friction between the cylinder and the magnetic switch, making the installation more secure.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: after the magnetic induction switch is fixed to the device using straps, the straps are easily subject to physical wear and chemical damage, resulting in strap damage, which in turn causes the magnetic induction switch to loosen, shift or even be damaged, affecting the normal operation of the magnetic induction switch.

[0005] Therefore, this utility model provides a strap-type magnetic induction switch. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where, after a magnetic induction switch is fixed to a device using a strap, the strap is easily subject to physical wear and chemical damage, leading to strap damage and thus the risk of the magnetic induction switch becoming loose, shifting, or even damaged, affecting the normal operation of the magnetic induction switch. Therefore, this invention proposes a strap-type magnetic induction switch.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a strap-type magnetic induction switch, comprising an induction switch body, two strap bodies fixedly mounted on the surface of the induction switch body, a connecting frame fixedly mounted on the end of the strap body away from the induction switch body, bolts slidably connected inside the two connecting frames, nuts threadedly connected to the surface of the bolts, mounting holes opened on the surface of the connecting frames, pins slidably connected to the inner wall of the mounting holes, a protective frame fixedly fitted on the surface of the pins, and a cylinder threadedly connected to the surface of the pins.

[0008] The effect achieved by the above-mentioned components is that after the magnetic induction switch is fixed to the device using straps, the straps are protected, reducing the damage to the straps. This reduces the risk of the magnetic induction switch becoming loose, shifting, or even damaged due to strap damage, and increases the service life of the magnetic induction switch.

[0009] Preferably, four rotating rods are fixedly inserted inside each of the two cylinders, and a retaining plate is fixedly installed on the surface of the pin.

[0010] The effect achieved by the above components is that the cylinder can be rotated by means of the rotating rod, and the clamping plate can be placed on the surface of the cylinder where the pin moves out.

[0011] Preferably, a connecting pad is fixedly installed on the surface of both protective frames, and the connecting pad is a sealing pad.

[0012] The effect achieved by the above components is that the connecting pad can reduce the gap between the protective frame and the equipment, thereby better protecting the straps.

[0013] Preferably, both of the strap bodies have a wear-resistant layer on their surfaces, and the wear-resistant layer is a polyamide layer.

[0014] The effect achieved by the above components is that the wear-resistant layer can increase the wear resistance of the straps.

[0015] Preferably, the surface of the inductive switch body is provided with an anti-slip layer, which is a rubber layer.

[0016] The effect achieved by the above components is that the anti-slip layer can increase the friction between the inductive switch and the device.

[0017] Preferably, each of the two connecting frames has a limiting hole on its surface, and a limiting post is fixedly inserted inside the connecting frame, the size of which is adapted to the size of the limiting hole.

[0018] The effect achieved by the above components is that the two connecting frames can be aligned with the limiting posts and limiting holes, thus making it easier for workers to fix the two connecting frames.

[0019] In summary:

[0020] In this invention, when a magnetic induction switch needs to be fixed to a device, the magnetic induction switch is first placed on the device. Then, the two connecting brackets are aligned using the limiting post and limiting hole. A bolt is then inserted into the connecting bracket, and a nut is placed on the bolt. The bolt is then rotated, and the bolt moves towards the connecting bracket using its thread. After the nut moves a certain distance, its surface presses against the connecting bracket, thus fixing the two connecting brackets together. The magnetic induction switch is then fixed to the device by the strap and the connecting bracket. Next, the protective bracket is moved. When the connecting pad on the protective bracket contacts the magnetic induction switch, the movement of the protective bracket is stopped. Then, the cylinder is rotated using a rotating rod, and the cylinder moves towards the protective bracket using its thread. After the cylinder moves a certain distance, its surface presses against the protective bracket, thus fixing the protective bracket and the connecting bracket together. The protective bracket protects the strap, reducing damage to it. The effect of these components is that after the magnetic induction switch is fixed to the device using the strap, the strap is protected, reducing damage to the strap and thus reducing the risk of loosening, displacement, or even damage to the magnetic induction switch caused by strap damage, thereby increasing the service life of the magnetic induction switch.

Four rotating rods 16 are fixedly inserted inside the two cylinders 15, and a locking plate 14 is fixedly installed on the surface of the pins 13. The cylinders 15 can be rotated by means of the rotating rods 16, and the locking plate 14 can be placed on the cylinders 15 and moved out of the insertion position. Connecting pads 5 are fixedly installed on the surface of pin 13 and the surfaces of the two protective frames 2. The connecting pads 5 are sealing pads. The connecting pads 5 can reduce the gap between the protective frame 2 and the equipment, thereby better protecting the straps. The surfaces of the two strap bodies 6 are provided with wear-resistant layers 7. The wear-resistant layers 7 are polyamide layers. The wear-resistant layers 7 can increase the wear resistance of the straps. The surface of the inductive switch body 1 is provided with anti-slip layers 8. The anti-slip layers 8 are rubber layers. The anti-slip layers 8 can increase the friction between the inductive switch and the equipment. Limiting holes 11 are opened on the surfaces of the two connecting frames 3. Limiting posts 12 are fixedly inserted inside the connecting frames 3. The size of the limiting posts 12 is adapted to the size of the limiting holes 11. The two connecting frames 3 can be aligned with the limiting posts 12 and the limiting holes 11, thereby making it convenient for the staff to fix the two connecting frames 3.

[0029] Working principle: When it is necessary to fix the magnetic induction switch to the equipment, first place the magnetic induction switch on the equipment, then align the two connecting brackets 3 with the limiting post 12 and the limiting hole 11, then insert the bolt 9 into the connecting bracket 3, then put the nut 10 on the bolt 9, and then rotate the bolt 9. The bolt 9 moves closer to the connecting bracket 3 by means of the thread. After the nut 10 moves a certain distance, the surface of the nut 10 presses against the connecting bracket 3. At this time, the two connecting brackets 3 are fixed together. At this time, the magnetic induction switch is fixed to the equipment by the strap and the connecting bracket 3. Then move the protective frame 2. When the connecting pad 5 on the protective frame 2 contacts the magnetic induction switch... Stop moving the protective frame 2, and then rotate the cylinder 15 with the help of the rotating rod 16. The cylinder 15 moves closer to the protective frame 2 by means of the thread. After the cylinder 15 moves a certain distance, the surface of the cylinder 15 presses against the protective frame 2. At this time, the protective frame 2 and the connecting frame 3 are fixed. At this time, the protective frame 2 can protect the strap and reduce the damage to the strap. The effect achieved by the above components is that after the magnetic induction switch is fixed to the equipment with the strap, the strap is protected, reducing the damage to the strap. This reduces the risk of the magnetic induction switch loosening, displacement or even damage caused by the strap damage, and increases the service life of the magnetic induction switch.
