Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a clamp, in particular to a nut locking clamp. Background Art

[0002] The automobile stabilizer bar is an auxiliary elastic element in the automobile suspension. Its function is to prevent the vehicle body from excessive lateral roll when turning and improve ride comfort. The lateral stabilizer bar is a torsion bar spring made of spring steel, which is placed horizontally at the front and rear ends of the car. The middle part of the rod body is hinged to the frame with a sleeve, and the two ends of the rod are fixed to the left and right suspensions respectively. When the vehicle body only moves vertically, the deformation of the suspensions on both sides is the same, and the lateral stabilizer bar does not work. When the vehicle body rolls, the suspensions on both sides jump inconsistently, the lateral stabilizer bar twists, and the elastic force of the rod body becomes a resistance to continued roll, playing a role in lateral stability.

[0003] The stabilizer bar of an automobile is generally connected to the frame through a clamp. The structure of the stabilizer bar clamp is relatively simple. It is generally stamped into a U shape by a flat plate, and two screws pass through the clamp and are fixed to the frame. Therefore, the strength of ordinary clamps is not high.

[0004] For example, a boss nut connection stabilizer bar clamp (application number: 202021608881.2) disclosed in a Chinese patent document includes a U-shaped upper clamp and a lower clamp fixed to the lower side of the upper clamp, the upper clamp is provided with an upper fixing portion bent outward at both ends and the two fixing portions are arranged horizontally, and the lower clamp has a lower fixing portion at both ends, the upper fixing portion is provided with a connecting hole 1, the lower fixing portion is provided with a penetrating connecting hole 2, and the connecting hole 1 corresponds to the connecting hole 2 one by one, the upper fixing portion is provided with a boss nut, the lower end of the boss nut has a connecting portion, the connecting portion passes through the corresponding connecting hole 1 and the connecting hole 2, and the lower end of the connecting portion is flanged and rests on the edge of the connecting hole 2. However, the boss nut is easy to fall off, making the connection inconvenient and the structure unreliable. Summary of the invention
