Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to an adjustable inductive switch. Background Art

[0002] At present, induction switches are suitable for automatic lighting, ventilation, alarm and other purposes in corridors, stairways, warehouses, garages, basements, toilets and other places. For example, in daily life, families with children generally install alarms controlled by induction switches at the door of the room, so that they can find children running out of the room without permission at the first time to prevent accidents. However, common household induction switches are often fixed directly to the wall or various furniture with bolts. When the installation position and induction height need to be adjusted according to the actual usage, the induction switches fixed by bolts are difficult to disassemble and install, so there is room for improvement. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide an adjustable induction switch, which is easy to install and disassemble, and the induction height can be freely adjusted to adapt to the changes in the height of children during their growth, so that it can be sensed and detected.

[0004] The utility model provides an adjustable induction switch, which includes an infrared induction switch and

[0006] The adjusting device comprises a sleeve, a button, a buckle, an adjusting plate, a fixing plate, a spring and a screw hole. The button is installed at the end of the sleeve, the buckles are fixed on the fixing plate, and the spring is located between two adjacent buckles.

[0007] Furthermore, the countersunk holes are located on both sides of the fixing seat, and there are two of them, which are symmetrically distributed in the center.

[0008] Furthermore, there are four magnet blocks, which are evenly distributed at the four corners of the bottom of the fixing base. When installed on a metal surface, they can be directly adsorbed by the magnet blocks, which simplifies the installation steps and makes subsequent disassembly extremely convenient.

[0009] Furthermore, the button is fixedly connected to the adjustment plate, and rotating the button can drive the adjustment plate to rotate in the sleeve, and two sides of the adjustment plate are in contact with the fixed plate.

[0010] Furthermore, the buckles are evenly distributed on the fixing plates, there are two fixing plates, which are symmetrically distributed in the sleeve, and the buckles move on the openings of the sleeve.

[0011] Furthermore, the spring is distributed between two adjacent buckles, and its two ends are connected to the inner wall of the sleeve and the fixed plate. Since the two sides of the adjustment plate are in contact with the fixed plate, when the adjustment plate rotates, the fixed plate will be pushed inward by the spring, driving the buckle to retract into the sleeve.

[0012] Furthermore, a bolt is provided at the end of the infrared induction switch, and is connected to the sleeve through the cooperation of the bolt and the screw hole.

[0013] Beneficial effects:

[0014] 1. The fixing device of the induction switch is provided with a countersunk magnet block.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

[0023] Below, an adjustable induction switch according to an embodiment of the utility model is described with reference to the accompanying drawings. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adjustable induction switch includes a fixing device, an adjusting device and an infrared induction switch 3;

[0024] The fixing device comprises a fixing seat 1, a countersunk hole 101, a magnet block 102 and a slot 103, wherein the countersunk hole 101 is located at both sides of the fixing seat 1, the magnet block 102 is embedded at the bottom of the fixing seat 1, and the slot 103 is located in a through hole on the fixing seat 1;

[0025] The adjusting device includes a sleeve 2, a button 201, a buckle 202, an adjusting plate 203, a fixing plate 204, a spring 205 and a screw hole 206. The button 201 is installed at the end of the sleeve 2, the buckles 202 are fixed on the fixing plate 204, the spring 205 is located between two adjacent buckles 202, and the two ends are connected to the inner wall of the sleeve 2 and the fixing plate 204.

[0026] Furthermore, the countersunk holes 101 are located on both sides of the fixing base, and there are two of them, which are symmetrically distributed in the center.

[0027] Furthermore, there are four magnet blocks 102 evenly distributed at the four corners of the bottom of the fixing base 1. When installed on a metal surface, it can be directly adsorbed by the magnet blocks 102, which simplifies the installation steps and is also extremely convenient for subsequent disassembly.

[0028] Furthermore, the button 201 is fixedly connected to the adjustment plate 203 , and rotating the button 201 can drive the adjustment plate 203 to rotate in the sleeve, and both sides of the adjustment plate 203 are in contact with the fixed plate 204 .

[0029] Furthermore, the buckles 202 are evenly distributed on the fixing plates 204 . There are two fixing plates 204 , which are symmetrically distributed in the sleeve 2 . The buckles move on the openings of the sleeve 2 .

[0030] Furthermore, the spring 205 is distributed between two adjacent buckles 202, and its two ends are connected to the inner wall of the sleeve 2 and the fixed plate 204. Since the two sides of the adjustment plate 203 are in contact with the fixed plate 204, when the adjustment plate 203 rotates, the fixed plate 204 will be pushed inward by the spring 205, driving the buckle 202 to retract into the sleeve 2.

[0031] Furthermore, a bolt 301 is provided at the end of the infrared sensor switch 3 , and the infrared sensor switch 3 is connected to the sleeve 2 through the cooperation of the bolt 301 and the screw hole.

[0032] In a specific embodiment: Figure 1 and Figure 2As shown, if it is installed on a non-metal surface, it can be fixed with bolts through the countersunk holes on the fixing base 1. If it needs to be installed on a metal surface, it can be directly fixed by magnetic attraction through the magnet block 102, which simplifies the installation steps and is more versatile.

[0033] In a specific embodiment: Figure 1 , Figure 3 and Figure 4 As shown, the adjusting plate 203 is driven to rotate by rotating the button 201. Since the two sides of the adjusting plate are in contact with the fixed plate, when the adjusting plate rotates, the fixed plate 204 is pushed inward by the spring 205, driving the buckle 202 to retract into the sleeve 2. Then the sleeve 2 can be inserted into the through hole on the fixing seat 1. After adjusting to the required height, the button 201 is rotated again, and the adjusting plate 203 pushes the fixing plate 204 to push the buckle 202 out, and cooperates with the slot 103 in the through hole of the fixing seat 1 to limit the position, thereby fixing the height of the sleeve 2.

[0034] Working principle: During installation, if it is installed on a non-metallic surface, it can be fixed with bolts 301 through the countersunk holes 101 on the fixing base 1. If it is installed on a metal surface, it can be directly installed by adsorption through the magnet block 102. When the height needs to be adjusted, the adjusting plate 203 is driven to rotate by turning the button 201. Since the two sides of the adjusting plate are in contact with the fixing plate, when the adjusting plate rotates, the fixing plate 204 will be pushed inward by the spring 205, driving the buckle 202 to retract into the sleeve 2. Then the sleeve 2 can be inserted into the through hole on the fixing base 1. After adjusting to the required height, turn the button 201 again, and the adjusting plate 203 pushes the fixing plate 204 to push the buckle 202 out, cooperating with the slot 103 in the through hole of the fixing base 1 to limit the position, thereby fixing the height of the sleeve 2.
