Description

Technical Field

[0001] The utility model is applicable to the technical field of information collection, and particularly relates to an infrared sensor mechanism. Background Art

[0002] At present, infrared sensors are sensors that use infrared rays to process data. They have the advantages of high sensitivity. Infrared sensors can control the operation of driving devices and are now widely used to detect the driving speed of road vehicles.

[0003] However, before using infrared sensors to detect the speed of vehicles on the road, the support frame at the bottom of the infrared sensor is often placed to improve the stability of the infrared sensor. When the support frame is expanded and adjusted, the support plate originally contracted on the outer side of the bottom of the support frame cannot be expanded and adjusted synchronously, which easily leads to different expansion distances when multiple groups of support plates are expanded and adjusted, affecting the stability of the infrared sensor. Therefore, we propose an infrared sensor mechanism. Utility Model Content

[0004] The main purpose of the utility model is to provide an infrared sensing mechanism, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An infrared sensing mechanism comprises a mounting plate, a mounting base is fixedly mounted on the top surface of the mounting plate, and an infrared speed meter is fixedly mounted on the top surface of the mounting base;

[0007] A hand push plate is rotatably mounted on the bottom surface of the mounting plate, a transmission rod is fixedly mounted on the bottom surface of the hand push plate, a fixed plate is sleeved on the bottom surface of the transmission rod via a damping bearing, a connecting block is fixedly mounted on the outer surface of the fixed plate, and one end surface of each connecting block away from the fixed plate is hinged to a support plate via a rotating shaft;

[0008] A rotating screw is fixedly installed on the bottom surface of the transmission rod, and a lifting sleeve is movably sleeved on the bottom surface of the rotating screw, and a pushing rod is hinged on the outer surface of the lifting sleeve through a rotating shaft. There are four groups of connecting blocks, and the number of pushing rods is the same as the number of connecting blocks. The surface of one end of the pushing rod away from the lifting sleeve is hinged to the outer surface of the support plate through a rotating shaft.

[0009] By adopting the above technical scheme, the vertical movement force of the lifting sleeve is converted into a driving force for the four groups of support plates on the outside of the fixed plate through the rotation transmission action of the rotating screw on the lifting sleeve and the transmission conversion action of the pushing rod, so that the four groups of support plates can be synchronously rotated and expanded with the hinge as the center of the circle, thereby reducing the labor consumption required for the operator to adjust the expansion and expansion, ensuring that the rotation expansion distance of the support plates is the same, thereby ensuring the stability of the use of the infrared speed meter.

[0010] As an optional solution of the technical solution of the present application, a non-slip pad cover is fixedly bonded to the outer surface of the bottom of each support plate.

[0011] By adopting the above technical solution, the contact friction force of the support plate after contacting the ground is improved through the structural effect of the anti-slip pad cover.

[0012] As an optional solution of the technical solution of the present application, a sweat-absorbing pad is fixedly bonded to the outer surface of the push plate.

[0013] By adopting the above technical solution, the pushing stability of the hand push plate by the operator is ensured by the structural effect of the sweat-absorbing soft pad.

[0014] As an optional solution of the technical solution of the present application, guide blocks are fixedly installed on both side surfaces of the top of the hand push plate, a guide groove is opened at the bottom of the mounting plate, and the guide block is slidably inserted into the guide groove, and the cross-section of the guide block and the guide groove are both T-shaped.

[0015] By adopting the above technical solution, the pushing and rotating stability of the hand push plate is ensured by the guiding sliding action of the guide groove on the guide block.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. An infrared sensing mechanism of the technical solution of the present application, the upper and lower ends of the pushing rod are respectively connected to the support plate and the outer side of the lifting sleeve through a rotating shaft, and the hand push plate and the rotating screw below are connected through a transmission rod, so that the operator only needs to rotate the hand push plate to drive the transmission rod and the rotating screw to rotate synchronously, combined with the rotating screw to drive the lifting sleeve to rotate and drive the lifting sleeve to move vertically synchronously, under the rotation transmission action of the pushing rod, the vertical movement force of the lifting sleeve is converted into a driving force for the four groups of support plates on the outer side of the fixed plate, so that the four groups of support plates can be synchronously rotated and expanded with the hinge as the center of the circle, reducing the labor consumption required for the operator to adjust the expansion and expansion, while ensuring that the rotation expansion distance of the support plates is the same, thereby ensuring the stability of the use of the infrared speed meter.

[0018] 2. An infrared sensing mechanism of the technical solution of the present application, through the guiding sliding action of the guide groove on the guide block, allows the operator to simply twist the push plate, and the push plate can only rotate in a circle under the mounting plate without lateral movement, thereby ensuring that the power required for the support plate to rotate and expand is provided.

[0023] like Figure 1-3 As shown, the utility model provides a technical solution: an infrared sensing mechanism, a hand push plate 2 is rotatably installed on the bottom surface of the mounting plate 1, a sweat-absorbing pad 3 is fixedly bonded to the outer surface of the hand push plate 2, guide blocks 4 are fixedly installed on both side surfaces of the top of the hand push plate 2, a guide groove 41 is opened at the bottom of the mounting plate 1, and the guide block 4 is slidably inserted into the guide groove 41, and the cross-sections of the guide block 4 and the guide groove 41 are both T-shaped.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a transmission rod 21 is fixedly installed on the bottom surface of the hand push plate 2, and a fixed plate 22 is sleeved on the bottom surface of the transmission rod 21 through a damping bearing, and a connecting block 23 is fixedly installed on the outer surface of the fixed plate 22, and each connecting block 23 is hinged to a support plate 24 at one end surface away from the fixed plate 22 through a rotating shaft, and a rotating screw rod 25 is fixedly installed on the bottom surface of the transmission rod 21, and a lifting sleeve 26 is movably sleeved on the bottom surface of the rotating screw rod 25, and a push rod 27 is hinged on the outer surface of the lifting sleeve 26 through a rotating shaft, and the end surface of the push rod 27 away from the lifting sleeve 26 is hinged to the outer surface of the support plate 24 through a rotating shaft.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a non-slip pad cover 28 is fixedly bonded to the outer surface of the bottom of each support plate 24.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a mounting base 11 is fixedly mounted on the top surface of the mounting plate 1, and an infrared speed meter 12 is fixedly mounted on the top surface of the mounting base 11.

[0027] During operation, when the infrared speed meter needs to be installed and used, the operator holds the fixed plate with one hand and pushes the hand push plate with the other hand. Under the rotation action of the guide groove on the guide block, the hand push plate can drive the transmission rod and the rotating screw to rotate synchronously. Combined with the rotation transmission action of the rotating screw on the lifting sleeve, the lifting sleeve is driven to be lifted vertically synchronously. Then, combined with the transmission conversion action of the push rod, the vertical movement force of the lifting sleeve can be converted into an outward driving force on the support plate, so that the support plate can be synchronously rotated and stretched outside the fixed plate until the support plate is fully stretched, so that the bottom of the support plate can be in contact with the ground at a certain angle, thereby providing corresponding support force for the infrared speed meter to measure the speed, and the infrared speed meter is started to detect the speed of vehicles on the road.
