Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-3, a thread protection type nut comprises a nut body 1, wherein an annular groove 2 is formed in the upper end face and the lower end face of the nut body 1, a soft air bag 6 is vulcanized in the annular groove 2, the outer side wall of the soft air bag 6 is in contact with the groove wall of the annular groove 2, a gasket 3 is fixedly connected to the free end face of the soft air bag 6, one part of the gasket 3 is located in the annular groove 2 and is in sliding connection with the side wall of the annular groove, the other part of the gasket 3 protrudes out of the end face of the nut body 1, and a soft rubber strip 4 is arranged on the inner ring side wall of the gasket 3 in a surrounding mode.

When actually screwing up this nut body 1, at first insert the screw head in nut body 1 lower extreme face, along with nut body 1's rotation, then each soft rubber strip 4 can rotate along the thread groove of screw rod to can carry out comprehensive clearance to the impurity dust on the thread groove of screw rod.

Further, when the screw rod got into nut body 1, a plurality of soft rubber strips 4 wherein can have the trend to the inboard removal of nut body 1 to make a plurality of soft rubber strips 4 can not be when nut body 1 and fastening object's terminal surface contact, soft rubber strip 4 protrusion outside causes nut body 1 can't laminate completely with the terminal surface of fastening object, and the soft rubber strip 4 of another terminal surface is outside protruding, can block the striking of external to terminal surface thread tooth.

Further, when nut body 1 constantly contacts with the terminal surface of fastening article, gasket 3 slides in to ring channel 2 this moment, and then extrudees soft gasbag 6, under initial condition, because soft gasbag 6 initial stage contacts with the cell wall of ring channel 2 promptly, then its pressurized deformation can laminate with the thread groove of screw rod gradually, thereby make the junction between screw rod and the nut body 1 totally sealed, effectively avoid impurity such as external rainwater to get into junction between them, avoid its junction to take place the corrosion, in addition, because soft gasbag 6 self has elasticity, then play the effect of similar shell fragment, make both interlocks inseparabler.

Referring to fig. 1 and 3, specifically, the front end of the soft rubber strip 4 is provided with a rubber round head 5.

The head of the soft rubber strip 4 is in contact with the thread groove of the screw rod in a point contact mode, so that the phenomenon that the friction is too large, the nut needs large torque when rotating, and time and labor are wasted.

Referring to fig. 1 and 3, specifically, the plurality of soft rubber strips 4 are spirally arranged, and the spiral angle is consistent with that of the nut body 1.

The spiral angle of the soft rubber strips 4 is consistent with the spiral angle in the nut body 1, so that the soft rubber strips 4 can rotate more smoothly in the thread grooves on the screw.

Referring to fig. 1-3, in particular, the size of the central hole surrounded by the plurality of soft rubber strips 4 is smaller than that of the nut body 1.

Such setting can guarantee that each soft rubber strip 4 contacts with the lateral wall of screw rod, and can make the soft rubber strip 4 on the terminal surface of nut body 1 relative with the fastening article lateral wall to the inside side bending, and then guarantees that the terminal surface of nut body 1 can laminate completely with the lateral wall of fastening article.

Referring to fig. 1-3, specifically, the soft rubber strip (4) is cylindrical.

The cylindrical soft rubber strip 4 is easy to machine and form, and is not easy to deform and lose efficacy when bent.

The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be covered by the present invention in the technical scope of the present invention, and the technical solution and the inventive concept of the present invention should be replaced or changed equivalently.
