[0028] A pressing frame 5 is provided on the end surface of the upper cover 4 for pressing and fixing the infrared detector chip placed in the chip mounting seat 31 provided on the needle seat 3;

[0029] The infrared movement rear component 2 is assembled on the back of the front PCB board 1, and a support plate 61 is symmetrically arranged in the chip mounting seat 31. A plurality of copper tubes 62 for plugging with the infrared detector chip pins are arranged on the support plate 61. The copper tubes 62 are electrically connected to the input end of the front PCB board 1.

[0030] Specifically, when the infrared detector chip is placed in the chip mounting seat 31, the infrared detector chip pins are inserted into the support plate 61 and finally inserted into the copper tube 62, so that the infrared detector chip is powered. The output end of the front PCB board 1 is electrically connected to the input and output end of the infrared core rear component 2.

[0031] Then, the upper cover 4 is turned over to cover the end surface of the needle seat 3, and the pressing frame 5 is negatively pressed on the surface of the infrared detector chip to provide soft contact.

[0032] Furthermore, in the embodiment, a buckle groove 44 is symmetrically provided on the end surface of the needle seat 3 , so that a finger can be inserted into the buckle groove 44 to pinch the side wall of the infrared detector chip and remove it from the chip mounting seat 31 .

[0033] Furthermore, the infrared lens 42 is screwed into the flange 41 through threads, and then the flange 41 is locked on the top of the upper cover 4 through four threaded holes.

[0034] It should be noted that the infrared lens 42 in the embodiment is coaxial with the infrared detector chip.

[0035] In the above technology, by opening and closing the needle seat 3 and the upper cover 4, the time-consuming and laborious steps of assembling the movement are omitted, the infrared detector chip is put in, and after the detection, the upper cover 4 is directly opened to take out the infrared detector chip.

[0036] As an embodiment further provided by the present invention, a concave groove 43 for mating with the pressing frame 5 is provided on the end surface of the upper cover 4, and the pressing frame 5 is a soft-based elastic member.

[0037] Specifically, when the upper cover 4 is closed and contacts the end surface of the needle seat 3, the pressure frame 5 of the soft-based elastic member will be embedded in the recessed groove 43, thereby applying negative pressure to the infrared detector chip and producing a certain damping effect while the embedding to avoid shaking during subsequent flipping.

[0038] The above-mentioned soft-based elastic member can be any known soft material such as rubber, silicone, etc.

[0039] As another embodiment further provided by the present invention, Figure 2 It can be seen that the embodiment also includes a base frame 7 and a fixing frame 8 for assembling the front PCB board 1, and the two are flipped and switched between a horizontal state and a vertical state through a hinge assembly 9.

[0040] Furthermore, the hinge assembly 9 includes a first hinge plate 91 and a second hinge plate 92, the first hinge plate 91 is fixed to the fixing frame 8, and the second hinge plate 92 is fixed to the base frame 7; and the second hinge plate 92 is provided with a waist groove 921, in which a round rod 93 is slidably arranged, and also includes a tension spring 94, one end of which is hung on the round rod 93, and the other end is fixed to the side wall of the first hinge plate 91.

[0041] Furthermore, an L-shaped mounting groove 71 is provided on the base frame 7, and the second hinge piece 92 is installed on the horizontal portion of the L-shaped mounting groove 71; and a limiting member 72 is rotatably provided on the L-shaped mounting groove 71, the limiting member 72 abuts against the end surface of the horizontal portion, and is used to keep the fixing frame 8 in a vertical state.

[0042] Specifically, the first hinged piece 91 and the second hinged piece 92 in the embodiment are composed of a plate and connecting ears arranged on opposite sides of the plate, and the connecting ears are perpendicular to the plate, and the first hinged piece 91 and the second hinged piece 92 are rotatably connected through the connecting ears;

[0043] Since the tension spring 94 in the embodiment exists, when Figure 1 When the horizontal state is switched to the vertical state, the tension spring 94 is deformed by tension and approaches the other end of the waist groove 921, and is finally blocked and stopped.

[0044] At the same time, the fixing frame 8 is turned over and maintained in a vertical state, and is stopped by the limiting member 72 and stops and remains in this state.

[0045] When switching to the horizontal state, the first hinged piece 91 is limited by the vertical portion of the L-shaped mounting groove 71 and remains in the horizontal position. Figure 1 That is, after reaching a predetermined angle during the flipping process, the tension spring 94 is deformed, thereby actively flipping and switching the state.

[0046] As another embodiment further provided by the present invention, sheet metal parts 81 for fixing the rear component 2 of the infrared movement are symmetrically arranged on the fixing frame 8 .
