Chinese patent CN202659686U has announced a kind of for the riveting nut on Metal Sheets for Body-manufacturing and Metal Sheets for Body-manufacturing, this riveting nut comprises: nut body, run through the female through hole of tool of described nut body and be arranged on the riveted joint positive stop lug boss on the outward edge of an end of described nut body, the outer wall of described nut body starts the progressive chap to the other end by the end being connected with described riveted joint positive stop lug boss.This model utility can improve for the installation efficiency of the nut on Metal Sheets for Body-manufacturing and installation precision.But this riveting nut structure is comparatively complicated, and installs and uses and be not to facilitate especially.
Chinese patent CN102758817A has announced a kind of EXPANSION ANCHOR BOLTS, comprise screw rod and nut with nut, described nut and screw rod are respectively arranged with the internal and external threads complementing one another, described nut is connected with screw flight, described nut is also provided with and is with female multiple intumescent sheet with respect to other one end of screw rod, and the interspersed nut of described screw rod is threaded with intumescent sheet.This EXPANSION ANCHOR BOLTS is simple in structure, cost of production is low, easy to manufacture, support swelling is solid effective.But the principle of the fixing sheet metal part of this EXPANSION ANCHOR BOLTS is fixing similar with plain bolt screw, less or weld in the situation that sheet metal part thickness is thinner the insufficient strength being fastenedly connected for soldered sheet metal part space.
Model utility content
The purpose of this utility model is exactly to provide a kind of simple in structure, easy to use quick installation expanding nut connecting fast for sheet metal part in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of quick installation expanding nut connecting fast for sheet metal part, comprise base plate, stationary cylinder and clamp, the middle part of described base plate is provided with a circular hole, and described stationary cylinder is fixed on the circumference place of circular hole, and described clamp is provided with two, be connected to the both sides of base plate, in the time of nature, the top engaging of two clamps links together, and covers the upside of stationary cylinder, in the time having screw upwards to push in stationary cylinder, the top of two clamps is softened and be separated.
Described clamp is the elastic component with knuckle being made up of wallboard and top board, and the bottom of wallboard is connected with the side of base plate, and upper end and the top board of wallboard are connected to form knuckle.
The wallboard height difference of two clamps, and the height difference of two wallboards thickness that is top board.
On described clamp, offer and strengthen the flexible U-shaped hole of clamp, this U-shaped hole extends downwardly into the bottom of wallboard from the middle part of top board.
Expanding nut of the present utility model and fastening screw trip bolt are used in conjunction with, two fastened plates are fastenedly connected, when use, two fastened plates all offer mounting hole, the base plate of expanding nut is stuck in the mounting hole of fastened plate above, fastened plate is below placed on to fastened plate downside above, and the mounting hole of fastened plate is below larger, can make the base plate of expanding nut be accommodated in the inner, fastening screw trip bolt is stretched into from the mounting hole of fastened plate below, and upwards advance, after stationary cylinder by expanding nut, fastening screw trip bolt touches the top board of the clamp of expanding nut, and the top board of two clamps is strutted, two clamps hold clamping fastening screw trip bolt, two fastened plates are fastened together.
Compared with prior art, the utlity model has following advantage and beneficial effect:
1, the utility model structure ingenious, design new, compare with existing welded nut fastening structure, only fastening screw trip bolt need be pushed to mounting plate square hole can complete installation, and the application of quick mounting nuts makes to have solved smoothly the fastening problem of connection of two sheet metal parts under the immovable condition of sheet metal component structure.
2, increase installation efficiency, original fastening means need to be purchased welded nut and welding equipment, and existing mode only need push fastening screw trip bolt square hole and can complete installation.
3, the utility model, in the situation that prior art is used welded nut in a large number, has carried out thorough change to original Installation Modes, without pre-welding nut in the situation that, reaches the object of quick installation mounting plate at substrate.Meanwhile, the advantage that cost is little, easily manufactured, installation efficiency is high makes it have larger application area.
