Description

A kind of nut facilitating installing/dismounting

Technical field

This utility model relates to nut interconnection technique field, facilitates installation to tear open particularly to one The nut unloaded.

Background technology

Nut is connector most commonly used during mechanical assembly, nut the most all with bolt Being threaded together, have the effect tightened up by connected piece, some occasions need with specific Spanner nut could be screwed on as instrument, but for needing frequent installation or removal Occasion, then probably due to do not carry spanner for the moment so that the installation or removal work of nut Inconvenient.

Summary of the invention

In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide one Plant the nut facilitating installing/dismounting, it is not necessary to spanner just can install or remove.

In order to achieve the above object, the technical scheme that this utility model is taked is:

A kind of nut facilitating installing/dismounting, including being provided with the nut body 1 of screwed hole 8, The horizontal through hole 7 of nut body 1 and the horizon bar of L-shaped removal rod 2 are connected, nut The end face of body 1 is provided with the first aperture 4, and the vertical rod of L-shaped removal rod 2 is provided with second Aperture 5, the one end of the disc spring 3 being wrapped on the horizon bar of L-shaped removal rod 2 is inserted in In one aperture 4, the other end is inserted in second orifice 5, the horizon bar top of L-shaped removal rod 2 Riveting movable with nut body 1.

The horizon bar top of described L-shaped removal rod 2 is provided with bellmouth 6, is bored by percussion Shape hole 6 makes the top of horizon bar expand, turn up, and makes L-shaped removal rod 2 and nut The movable riveting of body 1.

Advantage of the present utility model: by nut body 1, L-shaped removal rod 2 and disc spring 3 coordinate, it is not necessary to use spanner just can install or remove, simple in construction.

Accompanying drawing explanation

Fig. 1 is sectional view of the present utility model.

Fig. 2 is the sectional view of L-shaped removal rod 2.

Fig. 3 is the schematic diagram of this utility model installation or removal.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is made narration in detail.

With reference to Fig. 1, Fig. 2, a kind of nut facilitating installing/dismounting, including being provided with screwed hole 8 Nut body 1, the horizontal through hole 7 of nut body 1 and the horizon bar of L-shaped removal rod 2 are joined Closing and connect, the end face of nut body 1 is provided with the first aperture 4, L-shaped removal rod 2 vertical Bar is provided with second orifice 5, the disc spring 3 being wrapped on the horizon bar of L-shaped removal rod 2 One end be inserted in the first aperture 4, the other end is inserted in second orifice 5, L-shaped removal rod 2 Horizon bar top be provided with bellmouth 6, by tap bellmouth 6 top of horizon bar is sent out Life expands, turns up, and makes the movable riveting of L-shaped removal rod 2 and nut body 1.

Operation principle of the present utility model is:

With reference to Fig. 3, when disassembly is desired, by L-shaped removal rod 2 90-degree rotation, utilize thick stick Rod principle is pulled L-shaped removal rod 2 and is made nut body 1 around bolt 11 towards disassembly direction Rotation can realize disassembling function；When needs are installed, by bolt 11 through the second part 10 Match with the screwed hole 8 of the Kong Bingyu nut body 1 of the first part 9, L-shaped is dismantled Bar 2 90-degree rotation, utilize lever principle pull L-shaped removal rod 2 make nut body 1 around Bolt 11 and can realize installation function towards installation direction rotation；After having installed or removed, Owing to the reset response of spring 3 makes again L-shaped removal rod 2 set back thus reduce and take Space, easy installation and removal.
