Description

Technical Field

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

[0002] A magnetic sensitive switch, also known as a reed switch, is a switch that uses the ferromagnetism to paramagnetism of a temperature-sensitive material near the Curie temperature to achieve temperature control. It is a switching device with closed contacts. Existing reed switches need to be installed on the wall using expansion bolts. After the expansion bolts are driven into the wall, their position can no longer be adjusted, which results in a measurement error that will lead to an installation error of the reed switch.

[0003] The Chinese patent with publication number CN218215140U discloses an adjustable magnetic sensitive switch, including a reed switch body, a fixed block fixedly connected to the outer wall of the reed switch body, a mounting block movably connected to one side of the fixed block, a first through hole opened in the inner wall of the fixed block, and a second through hole opened in the inner wall of the mounting block. The adjustable magnetic sensitive switch is conducive to installing the reed switch body at different heights by aligning the first through hole opened in the inner wall of the fixed block with the second through hole opened in the inner wall of the mounting block at different positions, thereby realizing the function of being adjustable after installation, solving the problem of poor adaptability caused by the inconvenient adjustment of the fixed position after installation, and facilitating the clamping and positioning of the fixed block, thereby avoiding the problem of the reed switch body being easy to shake when installing the fastening bolts, and improving the stability during installation.

[0004] According to the above technical solution, after the first through hole opened on the inner wall of the fixing block and the second through hole opened on the inner wall of the mounting block are aligned at different positions, the fastening bolts are then screwed into the inner walls of the first through hole and the second through hole respectively for threaded connection, thereby completing the installation of the reed switch body. However, every time the position needs to be adjusted, personnel are required to disassemble and assemble the switch through bolts and other devices, which is not only time-consuming and labor-intensive, but also inconvenient for personnel to use.

[0022] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a magnetic sensitive switch which is easy to adjust through improvement. The technical solution of the utility model is:

[0024] like Figure 1 - Figure 3 As shown, a magnetic switch that is easy to adjust includes a mounting plate 1, through holes 11 are opened at four corners of the side wall of the mounting plate 1, expansion bolts are spirally installed at the through holes 11, and the mounting plate 1 is fixed by the expansion bolts, and also includes two fixing blocks 2;

[0025] Two fixed blocks 2 are fixedly installed on the side walls of the mounting plate 1, the two fixed blocks 2 are "L" shaped, and the two fixed blocks 2 are axially symmetrically distributed. A plurality of slots 21 are provided on the side walls of the fixed blocks 2. A slide plate 4 is slidably installed on the adjacent side walls of the two fixed blocks 2. The side walls of the slide plate 4 are respectively fitted with the side walls of the two fixed blocks 2. A connecting rod 6 is fixedly installed on the side walls of the fixed blocks 2. The connecting rod 6 passes through the slot 21. Two sliders 61 are fixedly installed on the side walls of the connecting rod 6. A sleeve 5 is slidably installed on the side walls of the connecting rod 6. Two slide grooves 51 are provided on the inner side walls of the sleeve 5. The slider 61 is slidably installed inside the slide groove 51. The sleeve 5 is fixed by the setting of the slide groove 51 to prevent the sleeve 5 from being separated from the connecting rod 6. Two blocks 52 are fixedly installed on the wall surface of the sleeve 5 close to the fixing block 2. The blocks 52 correspond to the slots 21. A fixing ring 41 is fixedly installed on the side wall of the slide plate 4 away from the mounting plate 1. The reed switch body 3 is arranged inside the fixing ring 41. An anti-skid pad is fixedly installed on the side wall of the sleeve 5. The setting of the anti-skid pad makes it easy for the staff to move the sleeve 5. A damping plate is fixedly installed on the inner side wall of the sleeve 5. The friction between the sleeve 5 and the connecting rod 6 is increased by the setting of the damping plate to prevent the sleeve 5 from shaking and causing the block 52 to be away from the slot 21.

[0026] During use, the sleeve 5 is first moved to make the block 52 away from the slot 21 on the fixed block 2. Then the user drives the connecting rod 6 to move by holding the sleeve 5, thereby driving the slide plate 4 to move and adjust the height of the reed switch body 3. When the height is set, the sleeve 5 is pushed to move the sleeve 5 toward the slide plate 4, so that the block 52 on the sleeve 5 is engaged with the slot 21. At this time, the sleeve 5 will drive the connecting rod 6 to be fixed in this position, so that the height adjustment of the reed switch body 3 is more stable, which improves the efficiency of adjusting the height of the reed switch body 3 and saves time and effort.

[0027] like Figure 1 and Figure 3 As shown, in one embodiment, a plurality of springs 71 are fixedly mounted on the side wall of the slide plate 4, and a protective block 7 is fixedly mounted on the other end of the spring 71. The protective block 7 is arc-shaped when viewed from above, and is distributed at equal angles along the axial center line of the reed switch body 3. The springs 71 and the protective blocks 7 are arranged so that the protective blocks 7 drive the springs 71 to deform, thereby buffering the slide plate 4. During use, when a collision occurs, the protective block 7 squeezes the springs 71 to deform the springs 71, thereby buffering the force generated by the impact and improving the protective effect on the reed switch body 3.

[0028] The specific working method is: during use, first move the sleeve 5 to make the block 52 away from the slot 21 on the fixed block 2, and then the user drives the connecting rod 6 to move by holding the sleeve 5, thereby driving the slide plate 4 to move, and adjust the height of the reed switch body 3. When the height is set, push the sleeve 5 to move the sleeve 5 toward the slide plate 4, so that the block 52 on the sleeve 5 is engaged with the slot 21. At this time, the sleeve 5 will drive the connecting rod 6 to be fixed in this position, so that the height adjustment of the reed switch body 3 is more stable, which improves the efficiency of adjusting the height of the reed switch body 3 and saves time and effort.

[0029] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
