Embodiment approach

[0045] According to an embodiment of the present invention, the mounting part 20 may include a hole 21 formed on the plate-shaped main body 10, the shape of the hole 21 is consistent with the shape of the nut 200, so that the nut 200 can be inserted and fixed on the Inside the hole 21.

[0046] Such as figure 2 As shown, in this embodiment, the nut is preferably a flange nut, which includes a nut body 210 and a flange surface 220 . During installation, the nut body 210 can be passed through the hole 21 upwards from the lower surface of the plate-shaped main body 10 , so that the flange surface 220 is closely attached to the lower surface of the plate-shaped main body 10 . The outer surface of the nut body 210 may be slightly larger than the size of the hole, so that there is an interference connection between the two, so that the nut can be firmly fixed on the nut holder.

[0047] In this embodiment, the nut is preferably a flange nut, but the present invention is not limit...

Abstract

The invention provides a nut fixed piece and a nut fixed structure, wherein, the nut piece comprises a plate-shaped main body, a connection part positioned at one end of the plate-shaped main body and an installation part positioned on the plate-shaped main body, wherein, the connection part is used for being detachably connected with a part needing to be installed with a nut; the installation part is used for detachably installing the nut. The nut fixed structure comprises a nut, a connection piece and a nut fixed piece of the invention; the connection piece is fixed on or is integrated with the part needing to be installed with a nut; an installation hole which can pass through a bolt connected with the nut is formed on the corresponding position of the nut hole and the hole of the nut fixed piece on the part needing to be installed with the nut; the nut can be detachably installed on the installation part which can be detachably connected on the connection piece. The active nut for later use does not need to be welded and is convenient for detaching and replacement, thus replacing a convex welded nut and solving the problem of the convex welded nut.

Description

technical field [0001] The invention relates to a nut fixing part and a nut fixing structure which can replace projection welding nuts. Background technique [0002] At present, in the parts where there is no space to fasten the nuts with tools such as wrenches, especially in closed and semi-closed cavities, the method of projection welding nuts is often used for fastening, that is, the nuts are projected onto the parts and screwed with a wrench. Fasten the bolts at the other end. [0003] However, projection welded nuts have many disadvantages. First of all, it is easy to cause the nut to be brittle due to the quenching effect during welding, which greatly shortens the service life of the nut and is easy to be damaged. When the projection welding nut is damaged, it is often impossible to replace it, resulting in the scrapping of parts and even the entire equipment, and even if it can be repaired, it is time-consuming and laborious. In addition, the welding process of pro...
