Abstract

The utility model discloses an embedded blind nut, comprising a hollow cylinder and a cone, wherein the conic section of the cone is connected with the inner side wall of the cylinder; the end part of the cylinder is provided with a nut edge body formed by a flange ring which extends outward from the outer wall; the outer wall of the cylinder which is arranged at the lower end of the nut edge body is provided with tooth ripples; the surface of the conic section of the cone is provided with tooth ripples; and the inner wall of the cone is provided with threads which are used for matching with a tool gun when in assembling. The embedded blind nut has the benefits that the tooth ripples arranged at the outer wall of the cone effectively increase the friction between the inner wall of the cylinder part and the outer wall of the conic part after a product is riveted, and prevents the conic section from slipping and loosening in the cylinder; and the tooth ripples which are arranged below a brim body effectively increase the friction between the outer wall of the embedded blind nut and a workpiece, prevents the embedded blind nut from sliding in a preset plate hole of the workpiece, and increases riveting firmness.

Description

Cap is drawn in embedding
Technical field
The utility model relates to a kind of fastening piece, is specially a kind of embedding and draws cap.
Background technique
Draw cap to have another name called Insert Nut, moment draws cap, Che Xiula cap, car to repair Insert Nut, embed Insert Nut, are bumped into and draw cap and be bumped into Insert Nut etc., is used for the fastening field of all kinds of sheet metals, tubing and process industries such as other plate of material material and tubing.Because of not needing to attack internal thread, do not need welded nut, riveted joint firmly, characteristics such as efficient is high, easy to use, use fit on widely at electromechanics such as automobile, aviation, railway, refrigeration, elevator, switch, instrument, furniture, decoration and light industrial goods.
That sells in the market draws the cap part that can come with some shortcomings, and only be suitable for on several plates to ten millimeters thickness, the tube wall such as it, and it is bigger etc. that it is contained in space shared on the workpiece.
The model utility content
The purpose of this utility model is the deficiency of drawing cap to exist at above-described, provides a kind of and can be used on thicker plate and the pipe, and directly riveting is gone in the workpiece, reduced its embedding that takes up room and draw cap.
The utility model is achieved in that to embed and draws cap that comprise hollow cylindrical body and cone, the tapering of cone is connected with cylindrical madial wall.
Described cylindrical end is provided with the shade body that forms from the outwardly directed bulge loop of outer wall, and the cylindrical body outer wall of shade body lower end is provided with groove.
The surface, tapering of described cone is provided with groove, and this groove can effectively increase the frictional force between riveted joint back cone outer wall and the cylindrical body inside.
Described groove can be vertical or horizontal.
The inwall of described cone is provided with screw thread, cooperates with instrument firearm when being used to assemble.
Described cone outer wall is provided with horizontal groove.
Minimum 1/5 of the cylinder length that is equivalent to of length that described groove is provided with in shade body lower end.
The length that described groove is provided with in shade body lower end is equivalent to 4/5 of cylinder length.
Described cone maximum outside diameter is identical with cylindrical external diameter.
Described cylindrical body and cone can use iron, aluminium, stainless steel, copper etc. and other metallic material to make.
Compared with prior art, the beneficial effects of the utility model are: the utility model is contained on the instrument firearm inserts the presetting in the plate hole of workpiece, the pulling instrument firearm, make the back tapering part be embedded into cylindrical body inside, outer wall expands and makes it to be fastened on the workpiece, the thicker workpiece of usefulness, particularly plate, tube wall that is suitable for the connection of various plates, tube wall workpiece.Be contained on the workpiece, draw cap to disconnect from about neutral position owing to embed, the back cone is embedded in the cylindrical body of front, and after its riveting was on workpiece, to draw cap just to reduce only about half of than general for its take up space, effectively reduces shared space; At the groove that the cone outer wall is provided with, effectively increase the frictional force between product riveted joint back column part inwall and the tapered segment outer wall, prevent that tapering part is loosening in the inner generation of cylindrical body landing; And the groove that shade body below is provided with plays to increase embedding the friction of drawing between cap and the workpiece preset holes inwall, prevent that the workpiece assembling from finishing after, run up during the product operation and produce and get loose, increase and rivet fastness.

Embodiment
Below in conjunction with accompanying drawing the utility model is embedded and to draw cap to be described in detail.
Cap is drawn in embedding, as shown in Figure 1, comprising can cylindrical hollow cylinder 1 and cone 2, and the tapering of cone 2 is connected with the madial wall of cylindrical body 1, under the effect of instrument firearm, cone 2 enters cylindrical body 1 makes cylindrical body 1 expansion draw the cap riveting on workpiece embedding.As shown in Figures 2 and 3, be provided with the shade body that forms from the outwardly directed bulge loop of outer wall in the upper end portion of cylindrical body 1, the outer wall of shade body lower end is provided with groove 3.Groove 3 can be vertical or horizontal.Minimum 1/5 of the cylinder length that is equivalent to of the length of shade body lower end groove setting.The preferred length that groove is provided with in shade body lower end is equivalent to 4/5 of cylinder length.The surface, tapering of cone 2 is provided with groove, to increase the frictional force between cone outer wall and the cylindrical body inside.Inwall at cone 2 is provided with screw thread, cooperates with instrument firearm when being used to assemble.Be provided with horizontal groove at the cone outer wall.Cone 2 maximum outside diameters are identical with the external diameter of cylindrical body 1.Described cylindrical body and cone can use iron, aluminium, stainless steel, copper etc. and other metallic material to make.
When using, the utility model is contained in (vizored body one end is near instrument) on the instrument firearm, presetting in plate hole or the pore of insertion workpiece, the pulling instrument firearm, cylindrical body 1 and cone 2 are disconnected from about neutral position, and the cone 2 of back is partially embedded into cylindrical body 1 inside, as shown in Figure 4, outer wall expands and makes it to be fastened on the workpiece, cooperates screw to connect other workpiece then.The utility model is suitable for the usefulness of the connection of various material plates, plumber's part.
The utility model is not limited to above-mentioned mode of execution, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also comprises these changes and modification.
