[0022] like Figure 1 As shown, a mine-use retractable rearview mirror bracket includes a fixed bracket 1-7, a mounting bracket 1-2, and fastening components. The fixed bracket 1-7 is used to fix it to a guardrail post. A rearview mirror 1-1 is installed at one end of the mounting bracket 1-2 along its length, and the other end of the mounting bracket 1-2 is inserted into the fixed bracket 1-7 with a clearance fit between them. The fastening components are configured to fix and release the fixed bracket 1-7 and the mounting bracket 1-2. The fixed bracket 1-7 has a fixed point I, and the mounting bracket 1-2 has multiple fixed points II. The mounting bracket 1-2 moves telescopically within the fixed bracket 1-7. After the corresponding fixed point II is aligned with the fixed point I, the fastening components cooperate with the aligned fixed points I and II to fix the mounting bracket 1-2 and the fixed bracket 1-7 together, thereby realizing the adjustment of the cantilever length of the rearview mirror 1-1.

[0023] The following provides a further explanation of the specific structure of the aforementioned fixed bracket, mounting bracket, and fastening components.

[0024] The fixed bracket 1-7 has a radial through hole I1-11 on its circumferential surface at the insertion interface, which serves as a fixing point I; the mounting bracket 1-2 has a plurality of radial through holes II1-12 on its circumferential surface along its length, which serve as fixing points II.

[0025] The fastening components include fasteners and two opposing connecting blocks 1-8. The connecting blocks 1-8 have arc-shaped surfaces on the sides facing the fixed bracket 1-7 and the mounting bracket 1-2, which are used to fit against the circumferential surfaces of the insertion points of the fixed bracket 1-7 and the mounting bracket 1-2. The two connecting blocks 1-8, the fixed bracket 1-7 and the mounting bracket 1-2 are fixed together by the fasteners.

[0026] In a further embodiment, multiple radial through holes II1-12 are evenly and alternately arranged on the mounting bracket 1-2; the connecting block 1-8 is provided with two radial through holes III penetrating the connecting block, and the spacing between the two radial through holes III is equal to the spacing between any two adjacent radial through holes II1-12; one fastener cooperates with the aligned radial through holes III, radial through holes I1-11 and radial through holes II1-12 to fix the two connecting blocks 1-8, the fixing bracket 1-7 and the mounting bracket 1-2 together; the other fastener cooperates with the aligned radial through holes III and radial through holes II1-12 to fix the two connecting blocks 1-8 and the mounting bracket 1-2 together.

[0027] In a preferred embodiment, the fasteners are bolt 1-3, nut 1-9, washer 1-3, and washer 1-10. Bolt 1-3 passes through aligned radial through holes III, I 1-11, II 1-12, washer 1-3, and washer 1-10. The two connecting blocks 1-8, the fixing bracket 1-7, and the mounting bracket 1-2 are fixed together by tightening bolt 1-3 with nut 1-9. Bolt 1-3 passes through aligned radial through holes III, II 1-12, washer 1-3, and washer 1-10. The two connecting blocks 1-8 and the mounting bracket 1-2 are fixed together by tightening bolt 1-3 with nut 1-9.

[0028] As shown above, the mounting tube of the mounting bracket 1-2 has multiple evenly distributed holes. These holes allow for different positions to be selected when connecting with the fixed bracket 1-7, thus enabling flexible adjustment of the extension length of the mounting bracket 1-2. This design can both limit the length of the rearview mirror during vehicle transportation to improve safety and allow for length adjustment according to actual needs during use. The connecting block 1-8 used at the connection between the fixed bracket 1-7 and the mounting bracket 1-2 adopts a face-to-face contact fixing method with the structural tubes of the fixed bracket 1-7 and the mounting bracket 1-2, which can effectively reduce breakage at the connection.

[0029] In a further embodiment, the fixed bracket 1-7 is provided with mounting point I and mounting point II. Mounting point I is fixed to the front of the guardrail post with fasteners (preferably bolts 1-6 and washers 1-5), and mounting point II is fixed to the side of the guardrail post with fasteners (preferably bolts 1-6 and washers 1-5).

[0030] In a further embodiment, the fixed bracket 1-7 includes a pipe frame, mounting plate I2-3, and mounting plate II2-5; the pipe frame consists of a connecting pipe I2-1, a connecting pipe II2-7 integrally manufactured or welded together, and a connecting pipe III2-6 fixed between the two; mounting plate I2-3 is fixed to the tail end of the connecting pipe I2-1, and mounting plate I2-3 has at least one mounting hole, which serves as mounting point I; mounting plate II2-5 is fixed to the tail end of the connecting pipe II2-7, and mounting plate II2-5 has at least one mounting hole, which serves as mounting point II.

[0031] In a further design, connecting pipe II2-7 is a bent pipe to avoid obstruction by the guardrail posts; mounting bracket 1-2 is a straight pipe inserted into connecting pipe II2-7, with radial through hole I1-11 on connecting pipe II2-7. The tail end of connecting pipe I2-1 is welded to mounting plate I2-3, and a reinforcing rib 2-2 is welded at the connection point; mounting plate II2-5 has a structure with a protruding center and recessed sides, the protruding center forming an arc-shaped groove, the tail end of connecting pipe II2-7 is welded into the arc-shaped groove, and a sealing plate 2-4 is welded to the tail opening of connecting pipe II2-7.

[0032] As shown above, the fixed bracket 1-7 is connected to the guardrail post via mounting plates I2-3 and II2-5 using bolts 1-5 and washers 1-6. Since the fixed bracket 1-7 is installed on the guardrail post from both the front and side, it provides a certain degree of stability compared to a unidirectional connection. The connecting pipe II2-7, which connects to the mounting bracket 1-2, is angled to effectively avoid obstruction by the handrail post, making it easier for the driver to observe the surroundings of the vehicle.

[0033] In summary, this utility model provides a retractable rearview mirror bracket for mining applications, achieving the following functions and effects: This utility model employs a segmented design, dividing the rearview mirror bracket into a fixed bracket and a mounting bracket. Bolt fixing holes are provided on both the fixed and mounting brackets, allowing for a reliable connection via connecting blocks, bolts, washers, and nuts. The mounting bracket's mounting tube has multiple evenly distributed holes, allowing for flexible adjustment of the rearview mirror cantilever length by selecting different positions when connecting to the fixed bracket. This design not only limits the cantilever length during vehicle transport to reduce transportation risks but also allows for adjustment of the cantilever length according to actual usage needs, meeting the requirements of different working conditions.
