Description

an adjustable wrench

技术领域technical field

本实用新型属于装配技术，涉及一种可调节扳手。The utility model belongs to the assembly technology and relates to an adjustable wrench.

背景技术Background technique

目前的活扳手都是开口扳手，通过一个调节螺杆和齿条来调整活扳手的开口尺寸。其缺点是：当使用一段时间后，调节螺杆和齿条的啮合间隙增大，使开口尺寸的空程变大，当扭转力矩大时，扳手容易从螺栓头上滑脱，降低了扳手与螺栓头结合的可靠性。Current adjustable wrenches are all open-end wrenches, and the opening size of the adjustable wrench is adjusted by an adjusting screw rod and rack. Its disadvantages are: after using for a period of time, the meshing gap between the adjusting screw and the rack increases, which increases the gap of the opening size. When the torque is large, the wrench is easy to slip off from the bolt head, reducing the wrench and the bolt head. combined reliability.

本实用新型的技术方案是：一种可调节扳手，它由扳手头1和扳手柄3连接组成，扳手头1和扳手柄3由厚度相同的板材制造，扳手头1的外轮廓为圆形，扳手柄3为长条形，扳手头1的后端与扳手柄3的前端连接为整体，扳手柄3的后端为圆弧形，在扳手头1的上表面有一个与扳手头1同心的正方形的通孔2，在扳手头1的圆柱侧面上有一个沿径向与通孔2贯通的第一螺纹孔，第一螺纹孔的轴线垂直于通孔2被第一螺纹孔贯通的平面侧壁，第一紧定螺栓4拧在第一螺纹孔内，在扳手头1的圆柱侧面上还有一个沿径向与通孔2贯通的第二螺纹孔，第二螺纹孔的轴线垂直第一螺纹孔的轴线，第二紧定螺栓5拧在第二螺纹孔内。The technical solution of the utility model is: an adjustable wrench, which is composed of a wrench head 1 and a wrench handle 3, the wrench head 1 and the wrench handle 3 are made of plates with the same thickness, and the outer contour of the wrench head 1 is circular. The wrench handle 3 is elongated, the rear end of the wrench head 1 is connected to the front end of the wrench handle 3 as a whole, the rear end of the wrench handle 3 is arc-shaped, and there is a concentric hole with the wrench head 1 on the upper surface of the wrench head 1. The square through hole 2 has a first threaded hole radially connected to the through hole 2 on the cylindrical side of the wrench head 1, and the axis of the first threaded hole is perpendicular to the plane side through which the through hole 2 is penetrated by the first threaded hole wall, the first set bolt 4 is screwed in the first threaded hole, there is also a second threaded hole radially connected with the through hole 2 on the cylindrical side of the wrench head 1, the axis of the second threaded hole is perpendicular to the first threaded hole The axis of the threaded hole, the second set bolt 5 is screwed in the second threaded hole.

本实用新型的优点是：扳手与螺栓头结合的可靠性高，扭转力矩很大时，扳手也不会从螺栓头上滑脱。The utility model has the advantages that the reliability of the combination of the wrench and the bolt head is high, and the wrench will not slip off from the bolt head even when the torsional moment is large.
