Preferably, the bottom of the slot is in a V shape and is matched with the side corner shape of the hexagonal outer edge of the nut, and the left side and the right side which are parallel to the hexagonal outer edge are attached to the side edges of the slot.
Preferably, the nut fixing surface is pentagonal, four edges of the periphery of the nut fixing surface are parallel to the side edges and the bottom of the slot, the distance from the four edges to the edge of the slot is equal, and the remaining edge is provided with an opening of the slot.
Preferably, the welding flange is arranged on the side edge of the nut fixing surface parallel to the edge of the slot, and the welding flange is not arranged on the side edge of the opening of the slot to form an outlet for the nut to be separated from.
Preferably, the top of the hexagonal part of the nut is provided with a round angle, the height of two side edges of the slot is lower than the round angle, and the opening of the slot faces upwards.
The utility model discloses well nut installed part links to each other with the installation face welding through the welding turn-ups, and one side opening, corresponding nut when fixed with the slot bottom cooperation, prevent through the slot that the nut from rotating or droing. And if the nut damages, the utility model discloses can remove the nut along slot opening direction after dismantling the bolt, take out the nut that damages and be passing through the nut that the slot was more renewed. Therefore the utility model discloses can guarantee when bolted connection that the nut can not rotate or remove, still can change the nut after the welded fastening installed part simultaneously to easy operation has effectively reduced the cost of maintaining the production.

Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings for a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention by those skilled in the art.
As shown in fig. 1-2, the utility model provides a nut fixing device, including installing nut installed part and nut 1 on the installation face 2, the nut installed part is in nut 1 installs on installation face 2, the welding is in on installation face 2, the nut installed part includes nut stationary plane 3 and welding turn-ups 4, be equipped with on the nut stationary plane 3 with slot 5 that nut 1 links to each other, nut 1 with the cooperation of slot 5 bottom, welding turn-ups 4 follows 2 peripheral downward perpendicular turn-ups welding of installation face are in on installation face 2, slot 5 one end is in 3 marginal opening confession of nut stationary plane nut 1 deviates from.
The bottom of the slot 5 is in a V shape and is matched with the side corner shape of the hexagonal outer edge of the nut 1, and the left side and the right side which are parallel to the hexagonal outer edge are attached to the side edges of the slot 5. This prevents the nut from rotating better than relying on only two sides of the slot 5.
The nut fixing surface 3 is pentagonal, four sides of the periphery of the nut fixing surface 3 are parallel to the side edges and the bottom of the slot 5, the distance from the side edges to the edge of the slot 5 is equal, and the remaining side is provided with an opening of the slot 5. The welding flange 4 is arranged on the side edge of the nut fixing surface 3 parallel to the edge of the slot 5, and the welding flange 4 is not arranged on the side edge of the opening of the slot 5 to form an outlet for the nut 1 to be separated from.
The nut 2 is stopped by each side of the slot 5 in the process of dismounting the bolt, and because the distances between the welding flanging 4 and each side of the slot 5 are equal, the strength of each side is close, the moment can be better shared, and the phenomenon that one part has lower strength to cause deformation and damage a fixed structure is avoided.
The top of the hexagonal part of the nut 1 is provided with a round angle, the height of two side edges of the slot 5 is lower than the round angle, and the opening of the slot 5 faces upwards. Therefore, the nut 1 is enabled to slip in the slot 5 by preventing the round angle, meanwhile, the nut 1 is not easy to naturally fall off from the slot 5, and the nut 1 is convenient to place.
The utility model discloses when the installation, earlier connect bolt, nut 1 on installation face 2 fixed, put nut installed part on nut 1 again, let slot 5 bottom with nut 1 cooperatees, this is that arc notch 6 is in the same place with the top surface fillet cooperation of 1 hexagon part of nut, then welds 4 welding of welding turn-ups of nut installed part on installation face 2, and nut 1 receives blockking of 5 substructure of slot like this, can't rotate when the bolt loads and unloads, and arc notch 6 blocks nut 1 makes it can not reciprocate. If the nut 1 is damaged and needs to be replaced, the nut 1 slides out along the opening direction of the slot 5 after the bolt is dismounted, and then a new nut 1 is inserted into the nut mounting piece along the direction of the slot 5 and corresponds to the corresponding mounting hole, so that the bolt can be installed to complete the replacement of the nut 1.
The present invention has been described in detail with reference to the accompanying drawings, and it is apparent that the present invention is not limited by the above embodiments, and various insubstantial modifications of the inventive concept and technical solutions of the present invention or direct application of the inventive concept and technical solutions to other applications without modification are within the scope of the present invention.
