Detailed Description
As shown in fig. 1-4, a novel bracket with antirust coatings comprises two bottom brackets 1 which are symmetrically arranged, and a seat cushion 2 is fixedly arranged between the upper parts of the two bottom brackets 1, so that the two bottom brackets 1 and the seat cushion 2 form a whole.
The upper side ends of the two bottom supports 1 are respectively fixedly connected with the two ends of the bottom of the inverted U-shaped side support 3, and the middle of the side support 3 is fixedly provided with a backrest 4. The rear portion of the lateral support 3 is symmetrically provided with two connecting lugs 5 perpendicular to the rear portion, a first threaded hole 6 is formed in the free end of each connecting lug 5, second threaded holes 15 identical to the first threaded holes are formed in the two side portions of the lateral support 3, the two sides of the lateral support 3 are hinged to an adjusting pipe 8 through shaft pins 7 respectively, the distance between the first threaded hole 6 and the shaft pins 7 is equal to the distance between the second threaded hole 15 and the shaft pins 7, and hand-screwed screws 9 matched with the first threaded holes 6 are rotatably mounted at one end of each adjusting pipe 8.
The other end of each adjusting tube 8 is provided with a connecting rod 10 in an inserted manner, the inner peripheral wall of one end of each adjusting tube 8, which is in inserted fit with the connecting rod 10, is provided with a limiting convex ring 13, one end of each connecting rod 10, which is located inside the adjusting tube 8, is provided with a limiting convex head 14, and the outer diameter of the limiting convex head 14 is larger than the inner diameter of the limiting convex ring 13, so that the connecting rod 10 is prevented from being completely separated from the adjusting tube 8.
One end of each connecting rod 10, which is positioned outside each adjusting tube 8, is fixedly connected with a writing board 11, and a headrest 12 is fixedly arranged on the inner side of the writing board 11.
