[0001] The utility model relates to the technical field of infrared sensors, in particular to a spliced infrared sensor housing structure. Background Technique

[0002] An infrared sensor is a sensor that uses infrared rays for data processing. Infrared sensors are commonly used in non-contact temperature measurement, gas composition analysis, and non-destructive testing, and are widely used in fields such as medicine, military, space technology, and environmental engineering. For example, by using an infrared sensor to remotely measure the thermal image of the human body surface, abnormal temperature parts can be detected. In the prior art, an infrared sensor generally includes a housing and pins connected as a whole. A filter element, electrical components, and other devices are provided in the housing. However, the design of such an integrated infrared sensor easily leads to the need for overall replacement when one of the housing and pins fails, which is not only inconvenient for maintenance but also increases costs to a certain extent. Content of the Utility Model

[0003] In view of the above technical problems, the utility model provides a spliced infrared sensor housing structure, which can conveniently replace the pins of the infrared sensor, avoids replacing the infrared sensor body when the pins fail or are damaged, and reduces costs.

The bottom ends of the two moving rods respectively pass through two moving slots opened on the top end face of the mounting block and are fixedly connected to the adjacent ends of the two control blocks.

[0006] Preferably, the elastic member includes two second telescopic rods disposed in the control holes and located between the fixed block and the control block respectively. Each end of the two second telescopic rods is fixedly disposed on the end faces of the fixed block and one adjacent end of each control block respectively, and a second limit spring is movably sleeved on the rod body of each second telescopic rod; both ends of the second limit spring are fixedly connected to the end faces of the fixed block and one adjacent end of the control block respectively.

[0007] Preferably, the bottom end of the contact block is disposed on the bottom wall of the interface through a first telescopic rod, and a first limit spring is movably sleeved on the rod body of the first telescopic rod.

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the following combines specific embodiments and drawings to further elaborate the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.

[0020] Please refer to Figures 1-6 , a spliced infrared sensor housing structure, including a sensor body 2 provided on a base 1 and pins 6 detachably mounted on the base 1 through a mounting mechanism. The mounting mechanism includes a mounting block 3 fixedly sleeved on a plurality of pins 6, a contact block 11 disposed in an interface 7 opened on the bottom end face of the base 1 and in close contact with the pins 6, two clamping blocks 17 symmetrically arranged on the upper side of the mounting block 3 about the axis direction of the mounting block 3, and a control component disposed on the mounting block 3 and controlling the two clamping blocks 17 to approach each other. When the top end face of the mounting block 3 fits the bottom end face of the base 1, the clamping blocks 17 pass through a connecting hole 9 opened at the bottom end of the base 1 and are inserted into card slots 10 opened on the groove walls at the bottom ends of the two connecting holes 9 and away from each other.

[0021] As Figures 1-6As shown, when the pin 6 is damaged, the control component directly drives the two clamping blocks 17 to approach each other. At this time, the two clamping blocks 17 move from the clamping slots 10 into the connecting holes 9, and then the control component is used to drive the mounting block 3 to move downward in the direction of the bottom end of the base 1, so as to facilitate the removal of the pin 6 from the base 1. Then, a new pin 6 is installed on the sensor body 2. At this time, the control component drives the two clamping blocks 17 to approach each other, and the two clamping blocks 17 are respectively passed through the two connecting holes 9 opened on the bottom end face of the base 1. When the two clamping blocks 17 move to the bottom position, the control component is released. At this time, the two clamping blocks 17 move away from each other, so as to facilitate the two clamping blocks 17 to be respectively passed through different clamping slots 10, so as to facilitate the stable fixation of the position between the mounting block 3 and the base 1. And at this time, the top end of the pin 6 passes through the interface 7 and is in close fit with the contact block 11, so as to facilitate the installation between the pin 6 and the sensor body 2, so as to facilitate the replacement of the pin 6 when the pin 6 is damaged, avoiding the replacement of the whole sensor body 2, and the pin 6 of the sensor body 2 can be replaced conveniently, avoiding the replacement of the sensor body 2 when the pin 6 fails or is damaged, and reducing the cost.

[0022] The control component includes two control blocks 5 respectively slidably arranged at the two opening positions of the control holes 4 opened on the side surface of the mounting block 3, a fixing block 18 fixedly arranged at the middle position of the control hole 4 and located between the two control blocks 5, an elastic member arranged in the control hole 4 and connecting the two control blocks 5 and the fixing block 18, and two moving rods 16 which are parallel to each other and have different clamping blocks 17 fixedly connected to the side surfaces of the top ends far away from each other. The bottom ends of the two moving rods 16 respectively pass through the two moving slots 15 opened on the top end face of the mounting block 3 and are fixedly connected to the adjacent ends of the two control blocks 5.

[0023] The elastic member includes two second telescopic rods 19 respectively arranged in the control hole 4 and located between the fixing block 18 and the control block 5. The two ends of each second telescopic rod 19 are respectively fixedly arranged on the adjacent end faces of the fixing block 18 and each control block 5, and a second limiting spring 20 is movably sleeved on the rod body of the second telescopic rod 19; the two ends of the second limiting spring 20 are respectively fixedly connected to the adjacent end faces of the fixing block 18 and the control block 5.

[0024] As Figures 1-5As shown, when it is necessary to replace the pin 6, the control blocks 5 passing through the two openings of the control hole 4 are controlled to approach each other. At this time, the two control blocks 5 will compress the second limiting spring 20 arranged between the fixed block 18 and the control block 5, and the moving rod 16 is convenient to drive the two clamping blocks 17 respectively arranged on the side surfaces of the tops of different moving rods 16 to approach each other, so as to facilitate passing the two different clamping blocks 17 through different connecting holes 9. When the two clamping blocks 17 pass through the bottom positions of the connecting holes 9, the control of the two control blocks 5 is released. At this time, under the elastic action of the second limiting spring 20, the two control blocks 5 will be driven to move away from each other, so as to facilitate driving the two clamping blocks 17 to pass through the clamping grooves 10 opened in the connecting holes 9 respectively through the two moving rods 16, so as to facilitate fixing the position between the mounting block 3 and the base 1. When the mounting block 3 is installed on the base 1, first pass the pin 6 on the top of the mounting block 3 through the interface 7 opened at the bottom end of the base 1. At this time, the top end of the pin 6 is in close contact with the contact block 11 passing through the interface 7, so as to facilitate ensuring the connection between the pin 6 and the sensor body 2 and ensuring that the pin 6 can be used normally.

[0025] As Figures 1-4 and Figure 6 shown, the bottom end of the contact block 11 is arranged on the bottom wall of the interface 7 through the first telescopic rod 12, and the first limiting spring 13 is movably sleeved on the rod body of the first telescopic rod 12. The two ends of the first limiting spring 13 are respectively fixedly connected to the bottom wall of the interface 7 and the end face of the contact block 11. When the top end of the pin 6 passes through the interface 7, the top end of the pin 6 first contacts the contact block 11 and then moves into the interface 7, so as to facilitate pushing the contact block 11 to move towards the bottom of the interface 7 and compressing the first limiting spring 13 sleeved on the rod body of the first telescopic rod 12, so as to facilitate ensuring the close contact between the contact block 11 and the top end of the pin 6 and the connection between the contact block 11 and the sensor body 2, so as to facilitate ensuring the connection between the pin 6 and the sensor body 2 and ensuring that the pin 6 can be used normally.

[0026] The bottom end of the contact block 11 is arranged on the bottom wall of the interface 7 through the first telescopic rod 12, and two magnets are movably sleeved at both ends of the rod body of the first telescopic rod 12. The two magnets are respectively fixedly arranged on the bottom wall of the interface 7 and the end face of the contact block 11; the adjacent ends of the two magnets have the same magnetic poles. When the top end of the pin 6 passes through the interface 7 and drives the contact block 11 to move towards the bottom of the interface 7, at this time, the adjacent ends of the two magnets have the same magnetic poles, so as to facilitate having a repulsive force between the two magnets to move away from each other, so as to facilitate ensuring that when the top end of the pin 6 drives the contact block 11 to move towards the bottom end of the interface 7, ensuring the close contact between the contact block 11 and the pin 6, ensuring that the pin 6 can be used normally, and facilitating the replacement of the pin 6 of the sensor body 2, avoiding replacing the sensor body 2 when the pin 6 fails or is damaged, and reducing the cost.

[0027] As Figures 1-6 shown, on the top end face of the mounting block 3, four positioning blocks 14 arranged in a circumferential array are fixedly provided. On the bottom end face of the base 1, a plurality of positioning grooves 8 matching the plurality of positioning blocks 14 are provided. When mounting the mounting block 3 on the base 1, first pass the positioning blocks 14 through the positioning grooves 8 provided on the base 1, thereby ensuring that the pins 6 can be stably passed through the interfaces 7, improving the mounting efficiency between the mounting block 3 and the base 1, that is, improving the mounting efficiency between the pins 6 and the sensor body 2.
