Description

Technical Field

[0001] The utility model relates to the technical field of sensor positioning, in particular to a thermopile sensor installation structure. Background Art

[0002] After searching, the utility model with the publication number CN214621494U proposes a new infrared thermopile sensor, including a base, a mounting seat, a mounting groove, an elastic sheet, and a reflective layer. The mounting seat is threaded with a rotating ring, and a push rod is provided on one end face of the rotating ring. A ball is rotatably embedded on the upper end of the push rod. The ball is in rolling contact with the other side of the elastic sheet. When the rotating ring is threaded on the mounting seat, the ball drives the elastic sheet to bend elastically toward the radial inner side of the mounting seat. The rotating ring is threaded on the mounting seat, so that the ball on the push rod pushes upward against the elastic sheet, so that the elastic sheet is elastically bent toward the radial inner side of the mounting seat, thereby reducing the reflection area of ​​the reflective layer to increase the reflection angle. When the rotating ring is threaded in the reverse direction, the reflection angle is reduced, and the reflection angle of the reflective layer can be adjusted. By providing a pin socket, the infrared thermopile sensor can be powered, and a compression spring is provided at the same time, so that the infrared thermopile sensor can be shock-absorbing and protected.

[0003] However, the above-mentioned prior art still has the following deficiencies when used: 1. The pins of the infrared thermopile sensor are plugged into the pin socket, and then a compression spring is installed between the pin socket and the mounting groove to achieve shock absorption protection for the infrared thermopile sensor. The compression spring has a shock absorption effect to a certain extent of movement, but cannot eliminate vibration. In other words, the pin socket will have a certain amplitude of vibration, which can easily cause the pin socket and the infrared thermopile sensor to become loose, affecting the reliability of the connection; 2. The compression spring is used to directly perform shock absorption, and according to its manual, it can be concluded that the pin socket can only move up and down for shock absorption, and does not have a lateral shock absorption function, and has the defect of poor shock absorption effect.

[0004] To this end, the utility model provides a thermopile sensor installation structure. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a thermopile sensor installation structure to solve the problems raised in the above-mentioned background technology. The utility model has the advantages of better anti-loosening effect of sensor body plug-in, universal shock absorption function, and better shock absorption effect.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a thermopile sensor mounting structure, including a sensor body and a mounting seat, the bottom of the sensor body is provided with pins, the top of the mounting seat is provided with a mounting groove, a socket with a shock-absorbing function is provided in the mounting groove, the socket and the pin are plug-connected, the socket is accommodated in the mounting groove and its outer peripheral wall is fixedly connected with at least three circumferentially evenly distributed arched clips, and the outer peripheral wall of the sensor body is provided with a groove that is clamped and adapted to the arched clip.

[0007] Furthermore, the plane where the arch clamp is located is parallel to the axis of the socket, and the outer arc surface of the arch clamp faces the axis of the socket.

[0008] Furthermore, the diameter of the circle where the free ends of at least three circumferentially evenly distributed arch clips are located is greater than the outer diameter of the bottom of the sensor body.

[0009] Furthermore, a guide sleeve is fixedly connected to the middle of the top of the socket, and a bell mouth with a large end facing outward is arranged on the top of the guide sleeve. A limit shaft plug-fitting with the guide sleeve is fixedly connected to the bottom of the sensor body.

[0010] Furthermore, a rubber sleeve is nested in the guide sleeve, and the inner diameter of the rubber sleeve is equal to the inner diameter of the limiting shaft.

[0011] Furthermore, a sink groove is provided at the bottom of the socket, an annular groove is provided on the inner wall of the sink groove, at least three circumferentially evenly distributed columns are fixedly connected to the bottom of the installation groove, and a rubber bag that abuts against the annular groove is fixedly connected to the top of the column.

[0012] Furthermore, a ventilation hole is provided on the outer peripheral wall of the mounting seat, which clamps the bottom and communicates with the mounting groove.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model arranges a plurality of circumferentially evenly distributed arched clamps on the outer circumference of the socket, so that the pins of the sensor body and the arched clamps can clamp the sensor body at the same time when plugged in. Therefore, when the socket vibrates, the entire sensor body will be driven to vibrate slightly as a whole, thereby effectively avoiding the problem of the pins being loose relative to the socket.

[0015] 2. The utility model arranges a plurality of circumferentially evenly distributed upright columns with rubber bags on the top at the bottom of the installation groove, and then opens a sink groove with an annular groove inside at the bottom of the socket. When the rubber bag is pressed in the annular groove, the entire socket is in a universal shock-absorbing state. Compared with the compression spring in the prior art, it has the function of shock-absorbing vibrations in all directions, greatly improving the shock-absorbing performance.

[0016] 3. The socket of the utility model is accommodated in the mounting groove, and then a ventilation hole connected to the mounting groove is opened on the outer peripheral wall of the mounting seat, so it has the advantage of ventilation and heat dissipation for the sensor body.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a thermopile sensor installation structure. This structure is an improvement on the structure in the patent document mentioned in the background technology. Therefore, the structure not disclosed in this application adopts the structure in the patent document mentioned in the background technology.

[0023] Therefore, the installation structure includes a sensor body 1 and a mounting seat 2, a pin 11 is provided at the bottom of the sensor body 1, a mounting groove 21 is provided at the top of the mounting seat 2, a socket 3 with a shock-absorbing function is provided in the mounting groove 21, and the socket 3 and the pin 11 are plug-connected, and the socket 3 supplies power to the sensor body 1 through the pin 11.

[0024] The socket 3 is accommodated in the mounting groove 21 and has at least three circumferentially evenly distributed arch clips 4 fixedly connected to its outer peripheral wall. The arch clips 4 are made of a material with elastic deformation (such as spring steel). The characteristics of the socket 3 accommodation make there be a gap between the outer peripheral wall of the socket 3 and the inner peripheral wall of the mounting groove 21. The outer peripheral wall of the sensor body 1 is provided with a groove 12 that is snap-fitted with the arch clip 4. When the pin 11 of the sensor body 1 is plugged into the socket 3, the circumferentially evenly distributed arch clips 4 will be squeezed into the groove 12. At this time, the entire sensor body 1 and the socket 3 are in a relatively tightly connected state. Compared with the prior art in which the pin 11 and the socket 3 are plugged in to support the entire sensor body 1, it can effectively prevent the pin 11 from loosening relative to the socket 3.

[0025] Furthermore, the plane where the arch clamp 4 is located is parallel to the axis of the socket 3, and the outer arc surface of the arch clamp 4 faces the axis of the socket 3. At this time, the groove 12 is an inner arch groove structure adapted to the arch clamp 4. When the arch clamp 4 clamps the sensor body 1, it will be in the groove 12. At this time, the clamping effect can be further improved, and it also has the function of preventing the sensor body 1 from twisting.

[0026] In this embodiment, the diameter of the circle where the free ends of at least three circumferentially evenly distributed arch clamps 4 are located is larger than the outer diameter of the bottom of the sensor body 1. This arrangement facilitates the docking of the sensor body 1 and the arch clamp 4. During docking, the top of the sensor body 1 is pushed downward, and the bottom of the sensor body 1 will push open the circumferentially evenly distributed arch clamp 4, wherein the arch clamp 4 is bent outward until it enters the groove 12 and is reset. Therefore, the docking of the sensor body 1 and the socket 3 is more labor-saving.

[0027] Furthermore, a guide sleeve 31 is fixedly connected to the middle of the top of the socket 3, and a bell mouth 311 with the large end facing outward is provided on the top of the guide sleeve 31. A limit shaft 13 that is plugged into and cooperates with the guide sleeve 31 is fixedly connected to the bottom of the sensor body 1. Before the pin 11 on the sensor body 1 is plugged into the socket on the socket 3, the limit shaft 13 can first enter the guide sleeve 31. Under the guidance of the guide sleeve 31, the sensor body 1 and the arch clamp 4 will not tilt when docking, which has the function of assisting the alignment of the pin 11 and the socket on the socket 3, so that the pin 11 can be smoothly inserted into the socket 3.

[0028] In this embodiment, a rubber sleeve 312 is nested in the guide sleeve 31, and the inner diameter of the rubber sleeve 312 is equal to the inner diameter of the limit shaft 13. The purpose of this arrangement is to avoid pulling out the sensor body 1. Due to the different pulling-out directions, the limit shaft 13 squeezes the inner wall of the guide sleeve 31, causing the guide sleeve to be squeezed to form a concave damage. It has the advantage of safely assisting the separation of the sensor body 1 and the socket 3.

[0029] In this embodiment, a sink groove 33 is provided at the bottom of the socket 3, and an annular groove 331 is provided on the inner wall of the sink groove 33. At least three circumferentially evenly distributed columns 211 are fixedly connected to the bottom of the installation groove 21, and a rubber bag 2111 that abuts against the annular groove 331 is fixedly connected to the top of the column 211. The rubber bag 2111 is a spherical bag structure filled with positive pressure gas, and a connecting hole is provided at the bottom of its outer spherical wall. The top of the column 211 is sleeved in the connecting hole by an interference fit, and the connecting hole and the column 211 can also be bonded and connected as needed to improve the tightness of the connection between the two.

[0030] Furthermore, the outer wall of the mounting base 2 is provided with a ventilation hole 22 which clamps the bottom and is connected to the mounting groove 21. Since there is a gap around the socket 3 and the mounting groove 21, the ventilation hole 22 is arranged to facilitate the discharge of heat in the mounting groove 21 to the outside, which has the advantage of better heat dissipation effect.

[0031] Working principle: Before use, first connect the mounting base 2 to the circuit board through the welding plate, and then when the sensor body 1 needs to be installed, hold the sensor body 1 and insert the limit shaft 13 at its bottom into the guide sleeve 31, and then push the sensor body 1 downward. When the outer edge of the bottom of the sensor body 1 is pressed against the outer arc wall near the top of the arch clips 4, press down hard, and the arch clips 4 are elastically swung outward and stretched. As the pin 11 is inserted into the socket 3, the arch clip 4 enters the groove 12 and resets. The entire sensor body 1 is in a state of tight connection with the socket 3. When the mounting base 2 vibrates, the universal shock absorption of the rubber bag 2111 can alleviate the impact force in any direction, and when the socket 3 vibrates slightly, it will drive the sensor body 1 to vibrate as a whole, which can effectively prevent the pin 11 from loosening relative to the socket 3.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
