Description

Technical Field

[0001] The utility model relates to the technical field of reed switch sensors, in particular to a reed switch device with enhanced sensitivity. Background Technique

[0002] A reed switch sensor is a sensor that works based on the principle of a reed switch. A reed switch is a switch sealed in a glass tube, which contains two or more iron reed pieces inside. When an external magnetic field approaches, the iron reed pieces will be attracted by the magnetic field, thus closing or opening the circuit. The reed switch sensor utilizes this characteristic to detect changes in the magnetic field.

[0003] After the sensor is installed, it is necessary to use a magnetic device to reciprocate through the triggerable area of the sensor to trigger the sensor. However, after the existing sensor and the magnetic device are installed, their positions are relatively fixed. When the distance between the sensor and the magnetic device remains unchanged, the magnetic force of the magnetic device determines whether the sensor is triggered. If the magnetic device is a magnet, the direct way to change the magnetic force for triggering is generally to change the distance between the magnet and the sensor, so that there is no need to replace magnets with different magnetic forces for triggering to enhance the trigger sensitivity of the device.

[0004] Therefore, it is necessary to design a reed switch device with enhanced sensitivity to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a reed switch device with enhanced sensitivity, which is used to solve the technical problems raised in the above background technique.

[0011] The beneficial effects of the technical solution provided by the present utility model compared with the prior art are as follows:

[0012] The utility model utilizes the rotation of a rotary knob, thereby driving the rotation of two rotating blocks. The lifting of a lifting block drives the reed switch body to lift synchronously, so as to adjust the distance between the reed switch body and a magnet. When the distance between the magnet and the sensor is not enough to trigger, instead of replacing the high-magnetic magnet to solve the problem, through the arrangement of a connecting block and a wire threading block, when a power connection wire passes through the wire threading block, the length of the power connection wire inside the housing can be reserved, so as to match the lifting adjustment of the reed switch body.

Detailed Embodiment

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0018] Obviously, many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0019] Please refer to Figures 1-3, the present utility model provides a reed switch device with enhanced sensitivity, including a housing 1. At the top of the housing 1, two symmetrically arranged rotating cover plates 2 are rotatably connected. At the bottom of the inner cavity of the housing 1, a fixed sliding support block 13 is fixedly connected. On one side of the inner cavity of the fixed sliding support block 13, two symmetrically arranged chutes are provided. On the other side of the fixed sliding support block 13 and on one side of the housing 1, two symmetrically arranged square sliding openings 17 are provided. Inside the two chutes, two rotating second rotating shafts 16 are slidably connected. One end of each of the two second rotating shafts 16 respectively penetrates outside the corresponding two square sliding openings 17 on one side of the housing 1 and the fixed sliding support block 13. On one side of the housing 1, an equipment box 3 is fixedly connected. At the end of each of the two second rotating shafts 16 inside the equipment box 3, a threaded sleeve plate 14 is fixedly inserted. Inside the equipment box 3, the two threaded sleeve plates 14 commonly threadedly sleeve a bidirectional threaded rod 15. One end of the bidirectional threaded rod 15 is fixedly connected with a rotary knob 5. On the outer surfaces of the two second rotating shafts 16 inside the fixed sliding support block 13, rotating blocks 12 are fixedly sleeved. At the top of each of the two rotating blocks 12, a first rotating shaft 11 is rotatably inserted. At the top of the two first rotating shafts 11, a lifting block 10 is commonly sleeved. At the top of the lifting block 10, a reed switch main body 9 is fixedly connected. On both sides of the reed switch main body 9, power connection lines 4 are provided. At the bottom of the inner cavity of the housing 1 on both sides of the reed switch main body 9, winding mechanisms are provided. The power connection lines 4 are wound on the winding mechanisms. The two power connection lines 4 respectively penetrate through both sides of the housing 1. Through the two rotating cover plates 2 that are rotatably opened at the top of the housing 1, when the reed switch main body 9 is lifted or lowered, conditions can be provided through the rotation of the two rotating cover plates 2, and when the reed switch main body 9 is inside the housing 1, the reed switch main body 9 can be protected. Through the winding mechanisms, a part of the lengths of the two power connection lines 4 can be wound inside the housing 1, and one end of each of the two power connection lines 4 is connected to equipment outside the housing 1. When the reed switch main body 9 is lifted or lowered, it can be ensured that the power connection lines 4 can be adjusted following the lifting or lowering of the reed switch main body 9. When the housing 1 is installed and the position of the reed switch main body 9 needs to be adjusted, by rotating the rotary knob 5, using the rotation of the bidirectional threaded rod 15, the two threaded sleeve plates 14 move towards or away from each other inside the equipment box 3. At the same time, the two second rotating shafts 16 are driven by the two threaded sleeve plates 14 to move towards or away from each other. Through the rotation of the bottom ends of the two rotating blocks 12, using the rotation of the two rotating blocks 12 at the bottom of the lifting block 10, the reed switch main body 9 is pushed to adjust its lifting position, so as to adapt to the adjustment of the magnet triggering distance, and thus it is not necessary to adjust magnets with different magnetic forces to change the triggering conditions of the device.

Thus, under the condition of facilitating the connection of the power connection wires 4, by the interaction of one end of the wire threading block 8 on the limit post 7, the length of the power connection wires 4 can be adjusted according to the lifting height of the reed switch body 9.

[0021] In order that when the bidirectional threaded rod 15 rotates, the two threaded sleeve plates 14 can move towards or away from each other inside the equipment box 3, the threaded sleeve plates 14 are square sheets, and the outer surface of the threaded sleeve plates 14 fits with the inner cavity of the equipment box 3, and the equipment box 3 is provided with an opening on one side of the outer shell 1.
