Description

Technical Field

[0001] The utility model relates to the field of infrared induction switches, in particular to an infrared induction switch with high installation adaptability. Background Art

[0002] The infrared induction switch is an automatic control switch based on infrared induction technology. It realizes its automatic control function by sensing the infrared heat emitted from the outside world. It can quickly turn on various electrical equipment such as lamps. It is widely used in corridors, stairways, warehouses, garages, basements, toilets and other places to realize home automation and property management automation.

[0003] The Chinese patent with announcement number CN220421803 U provides an infrared sensor switch with high installation adaptability. Through the structure of the charging interface, the infrared sensor switch with high installation adaptability can be replenished with power more conveniently when the power is insufficient, replacing the traditional method of replacing batteries. Through the structure of the heat-insulating back cover, the infrared sensor switch with high installation adaptability can better protect the internal components when it contacts a wall or machine with high temperature.

[0004] To sum up, the above structure requires workers to manually install the back cover and the shell cover through the bolt assembly during use, which wastes too much manpower and material resources during subsequent inspection and maintenance. In addition, the heat insulation sheet in the device will lose its viscosity when exposed to high temperature for a long time, causing the heat insulation sheet to fall off the back cover, which greatly affects the heat insulation effect of the device in high temperature areas. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an infrared sensing switch with high installation adaptability to solve the technical problems of excessive waste of manpower and material resources in subsequent inspection and maintenance, and the heat insulation sheet in the device will lose its viscosity when exposed to high temperature for a long time, which greatly affects the heat insulation effect of the device in high temperature areas.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an infrared induction switch with high installation adaptability, comprising a back cover and a shell cover, a heat insulation sheet is arranged in the interlayer of the back cover, and a hollow guide column is arranged on the back cover, spring sheets are symmetrically arranged on the inner side of the shell cover, and pressure feet are connected to the bottom ends of the spring sheets, a frame is arranged in the shell cover at the spring sheets, and the spring sheets are located inside the frame, and a clamping plate cooperating with the spring sheets is slidably arranged in the frame.

[0007] By adopting the above technical solution, the two-way threaded rod is rotated to make the clamp squeeze the spring sheet inward. At this time, the spring sheet drives the presser foot through the hollow guide column to be stuck in the interlayer of the back cover, thereby completing the assembly of the back cover and the shell cover. In this process, there is no need to use bolt assemblies to splice them, which greatly reduces the burden of subsequent staff on disassembly of the shell cover as a whole. When the spring sheet is stuck in the interlayer of the back cover, the presser foot can also be used to limit and fix the internal heat insulation sheet to prevent the heat insulation sheet from falling off at the back cover for a long time, thereby further ensuring the heat insulation effect of the device in high temperature areas.

[0008] The utility model is further configured that a lens is arranged on one side of the shell cover, and a control switch is arranged at the bottom of the lens.

[0009] By adopting the above technical solution, the device is started to work by controlling the switch, and infrared rays are used to sense external objects under the action of the lens, thereby achieving normal operation of the device in environments such as corridors.

[0010] The utility model is further configured that a bidirectional threaded rod is rotatably arranged in the frame, and the top of the clamping plate is threadedly connected with the bidirectional threaded rod.

[0011] By adopting the above technical solution, since the clamping plate and the bidirectional threaded rod are threadedly connected, the clamping plate on the outer wall will be driven to slide during the rotation of the bidirectional threaded rod, thereby driving the clamping plate to squeeze the outer wall of the spring sheet. The two groups of clamping plates squeeze the spring sheet inward, which is convenient for subsequently driving the presser foot to retract inward, and it can be directly inserted into the interlayer of the back cover through the hollow guide column.

[0012] The utility model is further configured that a guide rod is arranged on one side of the bidirectional threaded rod in the frame, and the outer wall of the guide rod is slidably connected to the clamping plate.

[0013] By adopting the above technical scheme, the stability of the sliding of the splint in the frame is guaranteed under the action of the guide rod, and the splint can be prevented from rotating along with the rotation of the bidirectional threaded rod, thereby achieving the role of limiting the splint and preventing the splint from rotating itself during the rotation of the bidirectional threaded rod.

[0014] The utility model is further configured that an array of mounting holes is provided through the rear cover.

[0015] By adopting the above technical solution, the rear cover can be easily installed in the designated area through the installation hole, and the firmness of the device in the designated area is further improved.

[0016] The utility model is further configured that the bottom of the presser foot is configured in a rough shape.

[0017] By adopting the above technical solution, the rough setting makes it easy to increase the friction between the presser foot and the heat insulation sheet, and effectively prevents the heat insulation sheet from slipping inside the back cover.

[0018] The utility model is further configured such that one end of the hollow guide column penetrates into the interlayer of the rear cover.

[0019] By adopting the above technical solution, the presser foot can be directly placed in the interlayer of the rear cover when the subsequent spring sheet is inserted.

[0020] The utility model is further configured that the frame is located at the middle position of the spring sheet.

[0021] By adopting the above technical solution, when the staff rotates the bidirectional threaded rod, the clamp in the frame will be driven to slide inward, so that when the clamp squeezes the spring sheet, the pressure foot at the bottom of the spring sheet can be retracted inward to the maximum extent, thereby ensuring that the pressure foot can follow the spring sheet and be inserted into the interlayer of the back cover. At the same time, the setting at the middle position can prevent the frame from limiting the hollow guide column, further improving the installation adaptability between the back cover and the shell cover.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model provides a hollow guide column on the rear cover, and rotates the bidirectional threaded rod to make the clamp plate squeeze the spring sheet inwardly. At this time, the spring sheet drives the presser foot to be stuck in the interlayer of the rear cover through the hollow guide column, thereby completing the assembly of the rear cover and the shell cover. In this process, there is no need to use a bolt assembly to splice them, which greatly reduces the subsequent staff's burden of disassembling the shell cover as a whole, and when the spring sheet is stuck in the interlayer of the rear cover, the presser foot can also limit and fix the internal heat insulation sheet, preventing the heat insulation sheet from falling off at the rear cover for a long time, thereby further ensuring the heat insulation effect of the device in a high temperature area.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1

[0032] An infrared sensor switch with high installation adaptability, such as Figure 1-Figure 4 As shown, it includes a back cover 1, a shell cover 2, a clamping mechanism, a sliding mechanism and a limiting mechanism. An array of mounting holes 5 are set through the back cover 1. The mounting holes 5 facilitate the installation of the back cover 1 in a designated area, further improving the firmness of the device in the designated area. At the same time, spring plates 8 are symmetrically arranged on the inner side of the shell cover 2, and the bottom ends of the spring plates 8 are connected with presser feet 12. A two-way threaded rod 7 is rotatably arranged in the frame 9, and the top of the clamping plate 10 is threadedly connected to the two-way threaded rod 7. Since the clamping plate 10 and the two-way threaded rod 7 are threadedly connected, the clamping plate 10 of the outer wall will be driven to slide during the rotation of the two-way threaded rod 7, thereby driving the clamping plate 10 to squeeze the outer wall of the spring plate 8. The two groups of clamping plates 10 make the spring plate 8 move inward. The side is squeezed to facilitate the subsequent driving of the presser foot 12 to retract inward, and it can be directly inserted into the interlayer of the back cover 1 through the hollow guide column 6. One end of the hollow guide column 6 penetrates into the interlayer of the back cover 1, so that when the subsequent spring piece 8 is inserted, the presser foot 12 can be directly in the interlayer of the back cover 1. In this process, the presser foot 12 is unfolded in the interlayer of the back cover 1 to achieve the splicing between the back cover 1 and the shell cover 2. In this process, there is no need to use bolt assemblies to splice them, which greatly reduces the subsequent staff's burden of disassembling the shell cover 2 as a whole. In addition, a heat insulation sheet is also provided in the back cover 1. The presser foot 12 can also be used to limit and fix the internal heat insulation sheet to prevent the heat insulation sheet from falling off at the back cover 1 for a long time, thereby further ensuring the heat insulation effect of the device in high temperature areas.

[0033] See also Figure 1 A lens 3 is provided on one side of the shell cover 2, and a control switch 4 is provided at the bottom of the lens 3. When in use, the device is started by the control switch 4 to work, and infrared rays are used to sense external objects under the action of the lens 3, thereby realizing the normal operation of the device in an environment such as a corridor.

[0034] See also Figure 3 and Figure 4 A guide rod 11 is provided on one side of the bidirectional threaded rod 7 in the frame 9, and the outer wall of the guide rod 11 is slidably connected to the splint 10. Under the action of the guide rod 11, the stability of the sliding of the splint 10 in the frame 9 is guaranteed. During the rotation of the bidirectional threaded rod 7, the splint 10 can be prevented from rotating with it, thereby achieving a limiting effect on the splint 10 and preventing the splint 10 from rotating itself during the rotation of the bidirectional threaded rod 7.

[0035] Embodiment 2

[0036] like Figure 3 An infrared induction switch with high installation adaptability is shown, and its overall structure is similar to that of the first embodiment, wherein the frame 9 is located in the middle position of the spring sheet 8. When the staff rotates the bidirectional threaded rod 7, the clamping plate 10 in the frame 9 will be driven to slide inward, so that when the clamping plate 10 squeezes the spring sheet 8, the presser foot 12 at the bottom of the spring sheet 8 can be retracted inward to the maximum extent, thereby ensuring that the presser foot 12 can follow the spring sheet 8 to be stuck in the interlayer of the back cover 1. At the same time, the setting at the middle position can prevent the frame 9 from limiting the hollow guide column 6, further improving the installation adaptability between the back cover 1 and the shell cover 2.

[0037] The working principle of the utility model is as follows: when in use, the back cover 1 is installed in the designated area through the action of the mounting hole 5, and a heat insulating sheet is arranged in the interlayer of the back cover 1, so that the device is conveniently installed on a wall with a higher temperature, and at the same time, the bidirectional threaded rod 7 on the shell cover 2 is rotated so that the clamping plate 10 in the frame 9 squeezes the spring sheet 8, and at this time, the presser foot 12 contracts inwardly and can penetrate into the interlayer of the back cover 1 under the action of the hollow guide column 6 to realize the installation of the back cover 1 and the shell cover 2. In this process, there is no need for the staff to hold the bolt assembly to splice them, which greatly reduces the subsequent maintenance burden, and at the same time, the presser foot 12 will limit and fix the heat insulating sheet under the action of the spring sheet 8 to prevent the heat insulating sheet from falling off at the back cover 1 for a long time, thereby further ensuring the heat insulation effect of the high temperature area of ​​the device.

[0038] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
