[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings. Example 1

[0025] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a high-precision flame detection device, which includes a flame detector body 1 and a fixing plate 2. Both ends of the fixing plate 2 are connected to an adjustment seat 3, and the adjusting seat 3 is rotatably connected to a connecting seat 4. One connecting seat 4 is fixedly connected to the flame detector body 1, and the other connecting seat 4 is fixedly connected to a mounting seat 6, and a positioning unit 5 is provided between the fixing plate 2 and the adjusting seat 3.

[0026] In the above technical solution, the positioning unit 5 connects the adjustment seat 3 with the connecting seat 4 and the fixed plate 2, and the fixed plate 2 can rotate around the adjustment seat 3, and the adjustment seat 3 can rotate within the connecting seat 4, thereby realizing the range adjustment of the flame detector body 1 in multiple directions and improving the adjustment accuracy.

[0027] The positioning unit 5 includes a slider 501 that is slidably connected to the adjustment seat 3, and two positioning columns 502 are abutted on one side of the slider 501. The positioning columns 502 are elastically connected to the fixed plate 2 and plugged into the adjustment seat 3. One end of the slider 501 is fixedly connected to a positioning plate 505, and the positioning plate 505 is snap-fitted with the connecting seat 4. The positioning unit 5 also includes two U-shaped rods 507 that are slidably fitted with the fixed plate 2, and the U-shaped rods 507 abut against the positioning columns 502.

[0028] Among them, a connecting seat 4 is connected and fixed to the connecting plate of the flame detector body 1, and mounting holes are opened at the corners of the mounting plate 6. After connecting tools such as bolts are passed through the mounting holes and connected to the wall, the mounting plate 6 is installed and fixed to the wall.

[0029] In the above technical solution, one end of the positioning column 502 is arranged in the adjusting seat 3, so that the fixing plate 2 can rotate with the axis of the positioning column 502 as the center of the circle. When the U-shaped rod 507 moves to drive the positioning column 502 to move, the positioning column 502 can be plugged into the adjusting seat 3 to limit the rotation, and at the same time drive the slider 501 to slide, so that the positioning plate 505 is engaged with the connecting seat 4, limiting the rotation of the adjusting seat 3 and the connecting seat 4.

[0030] The fixed plate 2 has a cavity structure, the positioning column 502 is slidably connected to the fixed plate 2, and one side of the positioning column 502 is elastically connected to the fixed plate 2 through a spring 503. When the positioning column 502 is not driven by external force, the spring 503 drives half of the positioning column 502 to be located in the cavity of the fixed plate 2, and the other end is located in the adjustment seat 3, so that the fixed plate 2 can rotate with the axis of the positioning column 502 as the center of the circle.

[0031] A through hole is provided on the adjustment seat 3, and one end of the positioning column 502 is provided in the through hole. A plurality of positioning bars 301 are fixed in a circular shape with equal intervals in the through hole. A positioning groove 504 is provided on the positioning column 502 to match the positioning bar 301. The positioning column 502 can rotate and slide in the through hole. When the positioning groove 504 moves to be plugged into the positioning bar 301, the positioning column 502 cannot rotate, so that the rotation node of the fixed plate 2 and the adjustment seat 3 is locked.

[0032] There are inclined surfaces on both sides of one end of the slider 501, and the positioning column 502 slides in cooperation with the inclined surfaces. When the positioning column 502 moves toward the middle of the through hole of the adjustment seat 3, its end portion slides in contact with the inclined surface, which can drive the slider 501 to move toward the side of the connecting seat 4, thereby driving the positioning plate 505 to be clamped with the connecting seat 4.

[0033] A plurality of positioning blocks 506 are fixedly provided in a circular shape with equal intervals on one side of the positioning plate 505, and a positioning groove 2 401 which is compatible with the positioning block 506 is opened on the connecting seat 4. When the slider 501 drives the positioning plate 505 to descend, the positioning block 506 abuts against the positioning groove 401, so that the positioning plate 505 cannot rotate in the connecting seat 4, so that the rotation node of the adjustment seat 3 and the connecting seat 4 is locked.

[0034] During use, the bolts are passed through the mounting holes of the mounting plate 6 and installed with the mounting surface to fix the mounting plate 5 on the mounting surface. Through the rotational cooperation between the adjusting seat 3 and the fixing plate 2, and the rotational cooperation between the connecting seat 4 and the adjusting seat 3, the flame detector body 1 can be adjusted in an angular range in multiple directions, so that the detection range of the flame detector body 1 coincides with the monitored range. Subsequently, when the U-shaped rod 507 moves toward the end of the fixing plate 2, it abuts against the positioning column 502, and the positioning groove 1 504 on the positioning column 502 is plugged into the positioning bar 301, so that the rotation node of the fixing plate 2 and the adjusting seat 3 is locked. When the positioning column 502 moves, it drives the slider 501 to slide, so that the positioning plate 505 is close to the connecting seat 4, and the positioning block 506 is engaged with the positioning groove 2 401, so that the rotation node of the adjusting seat 3 and the connecting seat 4 is locked, thereby limiting the flame detector body 1. Example 2

[0035] Reference Figure 4 , which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: an oblique groove is provided on one side of the positioning column 502, and the U-shaped rod 507 abuts against the oblique groove. A screw rod 508 is fixedly connected to the U-shaped rod 507, and a screw sleeve 509 is threadedly connected between the two screw rods 508.

[0036] In the above technical solution, the U-shaped rod 507 slides in cooperation with the cavity of the fixed plate 2, and an inclined surface is provided at the end of the U-shaped rod 507 to match the inclined groove of the positioning column 502. When the screw sleeve 509 is rotated, the two screws 508 approach each other or move away from each other. When the two screws 508 move away from each other, the two U-shaped rods 507 cooperate to drive the positioning column 502 to move, thereby realizing synchronous locking of each rotating node and simplifying the adjustment process.

[0037] The diameter of the screw sleeve 509 is greater than the thickness of the fixing plate 2 . The screw sleeve 509 protrudes from the fixing plate 2 and extends to the outside. The surface of the screw sleeve 509 is provided with multiple anti-slip grooves.

[0038] The remaining structures are the same as those of Example 1.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
