reclining device

Abstract

The invention is a kind of ease device, which utilizes a big head nut, a concave slot is opened in the big head nut, and an open cone washer is combined to be screwed on the stud. After being screwed, the cone washer expands in the big head nut, and the expanded cone washer becomes a flat washer, the outer dome is in the concave slot of the big head nut, and the inner dome is on the stud, so that the fastening effect is achieved.

Description

Technical fields:

[0001] This invention relates to a combination of a large-head nut and a conical washer, which, when screwed onto a screw, can better fix objects to equipment. Background technology:

[0002] Ordinary nuts are prone to loosening or falling off under high-frequency vibration, posing a safety risk during use. This invention's secure device utilizes the interaction between a large-cap nut and a tapered washer, providing a more effective way to fix objects to equipment. Summary of the Invention:

[0003] The purpose of this invention is to utilize the interaction between the large-head nut and the conical washer to prevent the nut from loosening or falling off under high-frequency vibration conditions.

[0004] The present invention is implemented as follows: A groove is made inside the large-head nut (1) (see attached figure). A conical washer (2) is placed into the groove (see attached figure). A flat washer (3) is placed in front of the conical washer (2). The flat washer (3) serves to support the expansion of the conical washer (2). Then, it is screwed onto the screw (4). After being tightened, the conical washer (2) will expand inside the groove of the large-head nut (1). After expansion, the conical washer (2) changes from a conical washer to a flat washer. The outer dome is inside the groove of the large-head nut (1), and the inner dome is on the screw (4), thus achieving a fastening effect. Attached image description:

[0005] Appendix Figure 1 This is a simplified structural diagram of an embodiment of the present invention. In the attached diagram, (1) is a large-head nut, (2) is a conical washer, (3) is a flat washer, and (4) is a screw. In the attached diagram, (1) is a large-head nut. A groove is made inside the large-head nut (1) for the conical washer (2) to use. The conical washer (2) in the figure is an open-shaped washer, (3) in the figure is a flat washer, and (4) in the figure is a screw. In the process of use, the conical washer (2) is placed into the groove of the large-head nut (1), the flat washer (3) is first put on the screw (4), and then the large-head nut (1) and the screw (4) are tightened. After tightening, the conical washer (2) will expand inside the groove of the large-head nut (1). After expansion, the conical washer (2) changes from a conical washer to a flat washer. The outer dome is inside the groove of the large-head nut (1), and the inner dome is on the screw (4), thus achieving a fastening effect.

Claims

1. A kind of fastening device uses a large-head nut (1), with a groove inside the large head of the large-head nut (1) to connect with a conical washer (2), and then tightened with a flat washer (3) and a stud (4). After tightening, the conical washer expands in the groove inside the large-head nut to achieve a fastening effect.

2. The comfort device according to claim 1, characterized in that... The large end of the large-head nut (1) is used. A groove is made inside it for the use of the conical washer (2).

3. The conical gasket (2) of the comfort device according to claim 2, wherein the conical gasket is an open-shaped conical gasket, characterized in that... The tapered washer (2) is screwed onto the screw rod (4) in conjunction with the large-head nut (1) and the flat washer (3). After tightening, the open-shaped tapered washer (2) expands in the groove inside the large-head nut (1). The expanded tapered washer (2) changes from a tapered shape to a flat washer. The outer dome is inside the groove of the large-head nut (1), and the inner dome is on the screw rod (4), which plays a fastening role.
