Description

Technical Field

[0001] The utility model relates to the technical field of substrate brackets, and particularly relates to a substrate bracket with adjustable angle. Background Art

[0002] An existing substrate bracket with adjustable angle includes a base, a left adjusting column, a right adjusting column, a left bracket, a right bracket, an adjusting screw rod, a screw rod seat, a connecting rod, and a turntable. The left adjusting column and the right adjusting column are oppositely arranged and are both fixed on the top surface of the base. The bottom ends of the left bracket and the right bracket are hinged together. An included angle is set between the left bracket and the left adjusting column, and the top end is hinged to the left adjusting column. An included angle is set between the right bracket and the right adjusting column, and the top end is hinged to the right adjusting column. The screw rod is parallel to the base and is rotatably installed on the screw rod seat. The left end is rotatably connected to the left adjusting column and is fixedly connected to the turntable. Rotating the turntable can drive the screw rod to rotate. The right end is hinged to one end of the connecting rod, and the end of the connecting rod far from the screw rod seat is hinged to a sliding seat on the left side surface of the left bracket. The sliding seat can slide along the length direction of the left bracket. A plurality of adjusting holes are formed in both the left adjusting column and the left bracket. Bolts pass through the adjusting holes at different positions on the left adjusting column and the left bracket, and the included angle between the left adjusting column and the left bracket can be changed. A plurality of adjusting holes are formed in both the right adjusting column and the right bracket. Bolts pass through the adjusting holes at different positions on the right adjusting column and the right bracket, and the included angle between the right adjusting column and the right bracket can be changed.

[0003] Although the above-mentioned substrate bracket with adjustable angle can change the included angle between the left bracket and the right bracket, the setting of a plurality of adjusting holes will reduce the strength of the left bracket, the left adjusting column, the right bracket and the right adjusting column, and further reduce the strength of the entire substrate bracket with adjustable angle, and it cannot well adapt to substrates of different lengths.

[0004] In view of the above deficiencies, it is necessary to design a substrate bracket with adjustable angle. Summary of the Utility Model

[0005] Therefore, the technical problem to be solved by the utility model is that in the existing substrate bracket with adjustable angle, the setting of a plurality of adjusting holes will reduce the strength of the substrate bracket and cannot well adapt to substrates of different lengths, so as to provide a substrate bracket with adjustable angle.

[0006] To solve the above technical problem, the technical solution of the utility model is as follows:

[0018] 1. For the angle-adjustable substrate bracket provided by the present utility model, since the first translation assembly is used to drive the mounting plate to move linearly to approach or move away from the second bearing plate, it can well adapt to substrate sizes of different lengths. Also, since the swinging assembly can drive the first bearing plate to swing around an axis to change the angle between the first bearing plate and the second bearing plate, compared with the design of changing the angle between the first bearing plate and the second bearing plate by the form of bolts passing through adjustment holes at different positions in the prior art, the strength of the angle-adjustable substrate bracket will not be reduced.
