Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example

[0029] like Figure 1-6 As shown, an embodiment of the present invention provides a protective device for an infrared thermal imager lens, comprising a thermal imager body 1 and a thermal imager grip 2 arranged below the camera body, a lens slot 9 is provided at one end of the thermal imager body 1, a lens body 10 is arranged in the lens slot 9, a mounting slot 3 is provided on the thermal imager body 1 outside the lens slot 9, a detachable mounting assembly 6 is installed in the mounting slot 3, and the detachable mounting assembly 6 is arranged to facilitate the installation of a protective cover 5, a sealing ring 7 is provided at one end of the mounting assembly 6 away from the lens, and a matching sealing cover 8 is provided on the sealing ring 7, and the lens body 10 will not be stuck with dust when not in use through the cooperation of the sealing ring 7 and the sealing cover 8;

[0030] The sealing ring 7 includes a ring body 701 installed at one end of the mounting assembly 6. An inner ring 702 is provided on the inner wall of the ring body 701. A ring groove 703 is provided on the inner ring 702. An embedding groove 704 is provided on the inner ring 702 located on one side of the ring groove 703.

[0031] The sealing cover 8 comprises a cover body 801, one end of which is provided with a flange 802, on which a connection block 803 matching the annular groove 703 is provided, and on which an embedding block 804 matching the embedding groove 704 is provided. The flange 802 is placed into the ring body 701, the connection block 803 on the flange 802 is inserted into the annular groove 703 of the inner ring 702, and then the cover body 801 is rotated to insert the embedding block 804 into the embedding groove 704, and the embedding block 804 is tightly connected with the embedding groove 704, thus completing the connection between the sealing cover 8 and the sealing ring 7. When it is necessary to open the sealing cover 8, the embedding block 804 can be separated from the embedding groove 704 by simply rotating in the opposite direction.

[0032] Furthermore, the mounting assembly 6 includes a mounting ring 601 connected to the ring body 701, and is connected to the ring body 701 through the mounting ring 601. The end of the mounting ring 601 away from the ring body 701 is provided with a mounting piece 602 adapted to the mounting groove 3. There are 3-4 mounting pieces 602 to facilitate the operation of the staff, and the mounting piece 602 is an elastic elastic metal sheet. The mounting piece 602 is made tightly attached to the inner wall of the mounting groove 3 through the elastic mounting piece 602. A card slot 4 is provided in the mounting groove 3. A mounting card block 603 adapted to the card slot 4 is provided at the end of the mounting piece 602. The cooperation between the card slot 4 and the card block prevents the mounting piece 602 from detaching, and the card block is tightly inserted into the card slot 4 through the cooperation of the elastic force of the mounting piece 602 to improve stability.

[0033] Of course, it is optional that a protective cover 5 is provided on the outer side of the mounting piece 602. The provision of the protective cover 5 can effectively protect the thermal imager lens.

[0034] Of course, it is optional that the inner diameter of the mounting ring 601 is larger than the inner diameter of the lens ring, the outer diameter of the ring body 701 is equal to the outer diameter of the mounting ring 601, and the inner diameter of the ring body 701 is equal to the inner diameter of the mounting ring 601, the outer diameter of the inner ring 702 is equal to the outer diameter of the flange 802, and the inner diameter of the inner ring 702 is equal to the inner diameter of the flange 802. Through this arrangement, the mounting ring 601 and the ring body 701 can be prevented from blocking the viewing angle of the thermal imager lens.

[0035] Of course, optionally, the embedding block 804 is an elastic block with elasticity, and the thickness of the embedding block 804 is greater than the thickness of the embedding groove 704. Through this setting, the embedding block 804 can fit tightly with the embedding groove 704.

[0036] Of course, it is optional that a placement groove 11 is opened on one side of the lens body 10, a thread 1 is arranged in the placement groove 11, and a thread 2 matched with the thread 1 is arranged on the flange 802. The placement groove 11 is provided to facilitate the placement of the sealing cover 8.

[0037] Of course, optionally, a handle 805 is provided at the other end of the cover body 801 , and the provision of the handle 805 facilitates the rotation of the cover body 801 .

[0038] Working principle: When in use, the staff can compress the installation sheet 602 inward, put the installation sheet 602 into the installation groove 3, and then loosen the installation sheet 602, and use the elastic force of the installation sheet 602 to tightly clamp the installation block 603 into the groove 4 to achieve the installation of the entire protective device, and then put the flange 802 into the ring body 701 through the handle 805, insert the connecting block 803 on the flange 802 into the ring groove 703 of the inner ring 702, and then rotate the cover body 801 to insert the embedding block 804 into the embedding groove 704, and the embedding block 804 is tightly connected with the embedding groove 704 to complete the sealing. The connection between the cover 8 and the sealing ring 7 can be opened by simply rotating in the opposite direction to disengage the embedding block 804 from the embedding groove 704, thereby separating the sealing cover 8 and the sealing ring 7; when the infrared thermal imager is needed, the sealing cover 8 can be unscrewed, and then the sealing cover 8 is placed in the placement groove 11, and the sealing cover 8 is conveniently placed by cooperating with the thread one and the thread two; after use, the sealing cover 8 can be reinstalled on the sealing ring 7; when the entire protective device needs to be disassembled, the entire protective device can be taken out by simply compressing the mounting piece 602 inward to disengage the mounting block 603 from the slot 4.
