[0028] The utility model is further described below in conjunction with the accompanying drawings.

[0029] See also Figures 1 to 10 The utility model provides an embodiment: an assembling device of an IR window and a ball cover, comprising a mounting seat 1, a first circular groove 101 is provided on the top of the mounting seat 1 for placing the ball cover 6, a second circular groove 102 is provided in the first circular groove 101, and a protrusion 103 for embedding into the groove 62 at the bottom of the ball cover 6 in the second circular groove 102 for positioning the ball cover 6; a plurality of telescopic cylinders 2 for pressing the IR window 4 are installed on the outer peripheral side of the mounting seat 1, the telescopic cylinder 2 can be a lever-type linear pressure plate cylinder, and the model can be ALC-32, but is not limited thereto, the IR window 4 can be pressed by the telescopic cylinder 2, which is convenient for subsequent assembly.

[0030] It also includes a bracket 3 and a sealing ring 5. The IR window 4 and the ball cover 6 can be assembled together through the bracket 3, and the sealing ring 5 can seal the product after the assembly is completed; the bottom of the bracket 3 has a plurality of clips 31, and the top of the ball cover 6 has a block 61 for the clips 31 to engage, and the IR window 4 and the ball cover 6 can be assembled together through the cooperation between the clips 31 and the block 61.

[0031] An annular groove 32 is provided at the bottom of the flange edge B of the bracket 3, and the inner bottom of the IR window 4 has a circular ring block, and an annular boss 41 matching the annular groove 32 is fixed on the circular ring block to facilitate the bracket 3 to rotate on the IR window 4; through the matching of the annular boss 41 and the annular groove 32, the bracket 3 can be positioned and the bracket 3 can be rotated on the IR window 4, which is convenient for the subsequent assembly of the IR window 4 and the ball cover 6.

[0032] The top of the IR window 4 has a flange edge A42 for pressing the telescopic cylinder 2, which facilitates the pressing of the telescopic cylinder 2.

[0033] A plurality of mounting blocks 8 are fixed on the outer peripheral side of the mounting seat 1 for mounting the telescopic cylinder 2. The telescopic cylinder 2 is mounted on the mounting block 8. The push rod of the telescopic cylinder 2 is connected to a pressing block 9. The pressing block 9 is driven downward by the telescopic cylinder 2 to press the flange edge A42, thereby pressing the IR window 4.

[0034] The present embodiment has the following working principle: the sealing ring 5 is installed on the flange edge C of the ball cover 6, and then the ball cover 6 with the sealing ring 5 is placed in the mounting seat 1, and then the IR window 4 is aligned with the ball cover 6 and placed in the mounting seat 1. At this time, due to the relationship between the sealing ring 5, the height between the IR window 4 and the ball cover 6 is greater than the thickness of the bracket 3, so that the bracket 3 cannot be fixed to the ball cover 6; but since the sealing ring 5 is elastic, the telescopic cylinder 2 is started at this time to drive the pressing block 9 to move downward, and when the pressing block 9 touches the flange edge A42, it continues to press downward. , until the height between the IR window 4 and the ball cover 6 is less than the thickness of the bracket 3, at which time the sealing ring 5 is compressed; then the annular groove 32 is aligned with the annular boss 41, so that the bracket 3 is placed on the IR window 4, and then the bracket 3 is rotated until the buckle 31 is located directly below the block 61, and the pressing block 9 is driven to move upward by the telescopic cylinder 2. Due to the resetting effect of the sealing ring 5, the IR window 4 and the bracket 3 are driven to move upward, so that the buckle 31 moves upward and is then blocked by the block 61, thereby completing the assembly of the IR window 4 and the ball cover 6.

[0035] In one embodiment of the utility model, the bottom groove of the ball cover 6 has a sticker 7, so that it can play a light-shielding role in order to prevent light refraction or dispersion in the area from affecting the imaging of the camera.

[0036] In one embodiment of the utility model, a valve 10 is installed on the telescopic cylinder 2. The valve 10 can be a straight-through speed-regulating one-way throttle valve, and the model can be PSA, but not limited to this, so that the gas flow speed can be adjusted and the pressure can be reduced or increased, which is convenient for the use of the telescopic cylinder 2. The valves 10 are connected in pairs through an air pipe 11 for conveying gas.

[0037] In one embodiment of the utility model, a pressure regulating valve 12 is further included. The pressure regulating valve 12 can be a digital precision pressure regulating valve 12, and the model can be IR2000-02BG, but not limited to this. The pressure regulating valve 12 can control the gas pressure in the cylinder.

[0038] In one embodiment of the utility model, a manual valve 13 is further included. The manual valve 13 can be a button switch manual valve 13, but is not limited thereto. The manual valve 13 can be used to control the opening or closing of the device.

[0039] Please continue reading Fig. 9 In one embodiment of the utility model, the annular boss 41 has a plurality of first notches 43, and the annular groove 32 has a plurality of second notches corresponding to the first notches, which can save materials.

[0040] In one embodiment of the utility model, the diameter of the ball cover 6 is larger than the diameter of the second circular groove 102 so that the ball cover 6 can be supported, and smaller than the diameter of the first circular groove 101 so that the ball cover 6 can be placed in the first circular groove 101 .

[0041] The telescopic cylinder, straight-through speed-regulating one-way throttle valve, digital precision pressure-regulating valve, and push-button switch manual valve in the utility model are all prior arts, and those skilled in the art are already well aware of them, so they will not be described in detail here. The utility model protects the structural features of an assembly device of an IR window and a ball cover.
