The adjustment component 120 includes a mounting disk 121, which has an upward-opening mounting cavity 201. A plug 122 is provided at the opening of the mounting cavity 201. A first gear frame 210 is fixed to the plug 122 inside the mounting cavity 201. A rotatable gear extending through the plug 122 is provided at the center of the first gear frame 210. A main gear 310 is provided on the shaft 220. A secondary gear 320 that meshes with the main gear 310 is provided on the side of the first gear carrier 210. A second gear carrier 230 is provided at the bottom of the mounting cavity 201. A gear ring 330 that meshes with the secondary gear 320 is provided on the side of the second gear carrier 230 along its circumference. A mounting shaft 231 that extends through the mounting disc 121 is provided on the second gear carrier 230. The flame detector body 100 is mounted on the extended end of the mounting shaft 231. A locking component 130 for locking the rotating shaft 220 is provided on the plug 122.

[0033] In this embodiment, the flame detector body 100 adopts the flame detector disclosed in patent number CN202836770U, which can adjust the detection angle and detection depth of the flame detector by changing the lens on the viewing window cover.

[0034] The mounting base 110 can be fixed to the mounting surface using fasteners such as bolts to enable the installation and use of the flame detector body 100.

[0035] The plug 122 is detachably installed at the opening of the mounting cavity 201 by screws, thereby better enabling the installation of structures such as the first gear carrier 210 and the second gear carrier 230 within the mounting cavity 201. In actual use, the outer wall of the mounting disc 121 is fixedly connected to the fixing base 110, so that the adjusting component 120 is set on the fixing base 110, combined with... Figure 4 As shown, in this embodiment, the first gear carrier 210 includes a column 410, and a mounting plate 420 is provided on the outer side of the column 410 and at the lower end. The upper end of the column 410 extends outward to form a mounting part 412. The mounting part 412 is fixedly installed at the center position of the lower side of the plug 122 by screws, thereby realizing the fixed installation of the first gear carrier 210 at the center position of the lower side of the plug 122, so that when the plug 122 is installed on the mounting disc 121, the first gear carrier 210 can be fixedly installed in the mounting cavity 201.

[0036] The upper end face of the column body 410 is provided with a bearing mounting groove 411, and the rotating shaft 220 is rotatably mounted in the bearing mounting groove 411 by a bearing, so that the rotating shaft 220 is rotatably mounted on the first gear frame 210. In actual use, the upper end of the rotating shaft 220 extends out of the plug cover 122, and the lower end rotatably abuts the center position of the second gear frame 230. The center position of the second gear frame 230 is provided with a mounting shaft 231 penetrating the installation disc 121, and the second gear frame 230 is rotatably mounted at the bottom of the installation cavity 201. The main gear 310 is fixedly mounted on the rotating shaft 220 between the first gear frame 210 and the second gear frame 230. The auxiliary gear 320 is rotatably mounted on the mounting plate 420 and meshes with the main gear 310, so that in actual use, rotating the extended end of the rotating shaft 220 can drive the main gear 310 to rotate, and in turn drive the auxiliary gear 320 to rotate. Since the gear ring 330 meshing with the auxiliary gear 320 is mounted on the second gear frame 230, the rotation of the auxiliary gear 320 can drive the gear ring 330 to rotate, so that the second gear frame 230 rotates in the installation cavity 201. Since the flame detector body 100 is connected to the mounting shaft 231 by threads, the rotation of the second gear frame 230 can drive the flame detector body 100 to rotate, so as to adjust the detection direction of the flame detector body 100. Compared with the prior art, the orientation of the flame detector body 100 can be adjusted in the horizontal direction by rotating the rotating shaft 220, and the adjustment operation is simple and convenient.

[0037] In the embodiment, the locking assembly 130 is provided, which can lock the rotating shaft 220 to avoid the orientation of the flame detector body 100 changing due to the misrotation of the rotating shaft 220 in actual use, thereby affecting the normal use of the flame detector body 100.

[0038] In combination with Figure 5 As shown in the figure, in the embodiment, the extended end face of the rotating shaft 220 is provided with a spring mounting cavity 341, the side wall of the spring mounting cavity 341 is provided with a sliding groove 342 along the axial direction thereof, the opening of the spring mounting cavity 341 is provided with a plug plate 260, and the spring mounting cavity 341 is provided with a liftable stop disc 510. The side wall of the stop disc 510 is provided with a sliding block 511 sliding in the corresponding sliding groove 342. The locking assembly 130 includes a lifting cylinder 240 sleeved on the extended end of the rotating shaft 220. The side wall of the lifting cylinder 240 is provided with a screw penetrating into the corresponding sliding block 511. The spring mounting cavity 341 is provided with a spring 250, which drives the stop disc 510 to move downward to drive the lifting cylinder 240 to press the upper side face of the plug cover 122 to fix the rotating shaft 220.

[0039] In the embodiment, the blocking plate 260 is detachably mounted on the extending end surface of the rotating shaft 220 by screws to block the spring mounting cavity 341, so that the baffle disc 510 and the spring 250 can be mounted in the spring mounting cavity 341.

[0040] The screw penetrates the lifting cylinder 240 and the sliding block 511, and the lifting cylinder 240 is fixedly connected to the baffle disc 510, so that the lifting cylinder 240 is slidably arranged outside the extending end of the rotating shaft 220. The cooperation between the sliding block 511 and the sliding groove 342 enables the rotation of the lifting cylinder 240 to drive the rotation of the rotating shaft 220, that is, the rotation of the lifting cylinder 240 can adjust the orientation of the flame detector body 100.

[0041] The spring 250 is arranged to push the baffle disc 510 downward to the bottom wall of the spring mounting cavity 341 in actual use, and then the lower end surface of the lifting cylinder 240 presses the upper side surface of the plug cover 122. Due to the friction between the two, the pressing of the lifting cylinder 240 on the plug cover 122 can prevent the rotating shaft 220 from rotating by mistake.

[0042] In actual use, in order to increase the friction between the lower end surface of the lifting cylinder 240 and the upper side surface of the plug cover 122, a rubber pad is fixed on the upper end surface of the plug cover 122 and surrounds the rotating shaft 220. The lower end of the lifting cylinder 240 extends outward to form a cooperating part 521, and the side surface of the cooperating part 521 towards the rubber pad is provided with a protruding spike that can penetrate into the rubber pad. The cooperating part 521 increases the cooperation area between the two, and the protruding spike penetrates into the rubber pad, thereby greatly increasing the friction between the two, and preventing the rotating shaft 220 from rotating by mistake.

[0043] In combination with Figure 5 As shown in the figure, in the embodiment, the outer side wall of the lifting cylinder 240 and the upper end part are oppositely provided with a lifting rod 522.

[0044] Through the structure in the embodiment, the user can conveniently lift and rotate the lifting cylinder 240 by the lifting rod 522, so that the operation of adjusting the orientation of the flame detector body 100 is simple and convenient.

[0045] Working principle: when the orientation of the flame detector body 100 needs to be adjusted, the lifting cylinder 240 is lifted by the lifting rod 522 to release the locking of the rotating shaft 220, and then the lifting cylinder 240 is rotated by rotating the lifting rod 522, thereby driving the rotating shaft 220 to rotate and adjusting the orientation of the flame detector body 100. After the adjustment is completed, the lifting rod 522 is loosened, the spring 250 drives the lifting cylinder 240 to move downward to press the upper side surface of the plug cover 122, so that the rotating shaft 220 is locked, and the rotating shaft 220 is prevented from rotating by mistake, which affects the use of the flame detector body 100.

[0046] In summary, the above is only the preferred embodiment of the present application, any changes and modifications made in accordance with the scope of the present application patent, should be the scope of the present application patent.
