Description

Technical Field

[0001] The utility model relates to the technical field of nut locking mechanisms, in particular to a nut locking mechanism. Background Art

[0002] A nut locking mechanism is a device used to secure a nut. It usually consists of a housing and one or more internal parts that can generate additional friction or resistance on the nut to prevent it from loosening. This mechanism is usually used in situations where it is necessary to prevent the nut from loosening due to vibration or external forces, such as in the connecting parts of mechanical equipment, automobiles, motorcycles, etc.

[0003] The connection between the display screen and the host of the existing laptop computer makes the opening and closing of the two easy to loosen after long-term use. Most of these structures do not have a structure for locking the nut. Under vibration or external force, the nut is easy to loosen by itself, and the internal nut and bolt need to be adjusted, which is troublesome to operate. Therefore, the utility model provides a nut locking mechanism to solve the problems raised in the above background technology. Utility Model Content

[0009] Furthermore, the opposite ends of the two No. 2 springs are respectively fixedly connected to the two push plates, and the two No. 2 springs are respectively movably sleeved with the two insertion rods;

[0010] According to the above technical solution, by arranging a No. 2 spring on one side of the push plate, after the push plate is pressed, the push plate can be reset due to the tension of the No. 2 spring.

[0011] Furthermore, the collar and the bolt are movably sleeved;

[0012] Through the above technical solution, the collar and the bolt are movably sleeved, so that the collar can rotate around the bolt.

[0013] Furthermore, a connecting plate is fixedly provided at the upper end of the collar, and a plurality of No. 2 through holes are opened at the front end of the connecting plate;

[0014] Through the above technical solution, a connecting plate is provided and a plurality of No. 1 through holes are provided on the front end thereof so as to be connected to a computer display screen.

[0015] Furthermore, a connecting rod is fixedly provided at one end of the bolt, and a plurality of No. 1 through holes are opened at the front end of the connecting rod;

[0016] Through the above technical solution, a connecting rod is arranged on one side of the bolt and a plurality of No. 1 through holes are opened at the front end of the connecting rod so that the bolt is connected to the computer motherboard.

[0017] Further, the bolt is configured to be made of carbon steel material;

[0018] Through the above technical solution, carbon steel has good strength and durability.

[0019] Furthermore, the first spring and the abutment plate are both movably sleeved with the bolt;

[0020] Through the above technical solution, the No. 1 spring and the support plate are movably arranged, so that the tension of the No. 1 spring can push the support plate to cooperate with the nut to clamp the ring.

[0021] The utility model has the following beneficial effects:

[0022] The utility model provides a nut locking mechanism, which presses down push plates on both sides, and after the push plates are pressed down, the insert blocks are also stored in the grooves, so that the nut can be rotated. By rotating the nut, the nut pushes the collar to one side, and a No. 1 spring and a push plate are provided on the other side of the collar. The tension of the No. 1 spring pushes the push plate to cooperate with the nut to clamp the collar, so that the tightness of the collar can be adjusted. After the nut is adjusted to a suitable position, the push plates on both sides are loosened, and due to the tension of the No. 2 spring, the two push plates are pushed to opposite sides, so that the insert blocks on the push plates can be inserted into the slots to lock the nut, thereby preventing the nut from loosening by itself under vibration or external force.
