Abstract
The utility model provides a fastening piece with an anti-falling function. The fastening piece comprises a head part (4) and a rod part (1) which are connected with each other to form a whole, wherein a thread matched with a nut is formed at the rod part. The fastening piece is characterized in that a groove (3) encircling the rod part is formed in the rod part close to the head part. The utility model has the beneficial effects that the head part of the fastening piece is extruded and embedded into a plate by an assembly tool; the groove can be used for filling redundant materials produced by extrusion of the head part during assembly, so that a phenomenon of unflatness of the plate caused by a reason that the redundant materials are extruded to the surface of the plate can be avoided; the redundant materials can flow into the groove, and then the anti-falling performance of the fastening piece is improved; and a bulge is formed in front of the groove, so that a guide function is realized, and the anti-push performance is improved. By the scheme, the working efficiency is improved, a phenomenon that the fastening piece gets loose because of vibration during working is avoided, the quality defect is reduced, and the potential safety hazard is avoided. The fastening piece can be applied to parts on which a riveting gun is difficultly used, such as a narrow space or an inner space of a box body and the like.
Description
Technical field
The utility model belongs to fastener areas, especially relates to having the bolt of preventing deviating from function or the fastening piece of screw class.
Background technique
Modal in the fastening piece is bolt and screw, and according to the needs of installing and using, it is of a great variety, and shape is also had nothing in common with each other.Be difficult to use under the situation of riveting gun then first-selected bolt of fastening connection piece or screw at small space or box house space etc.No matter be bolt or screw, all have head and bar portion, bar portion entire body or part periphery are provided with screw thread, and generally, screw then is to have Duoed individual tip on bar portion top than bolt, conveniently to carry out the self tapping operation.Screw or bolt are after the completion precession is passed the operation between the connected sheet material with bar portion in other words conj.or perhaps; If there is the part body of rod to expose connected body; Be the stable degree that reinforces the connection, on the body of rod that exposes, go back the rotation set upper cap nut sometimes, but in nut rotation set process; Bolt or screw possibly also can stressedly be pushed out a part; Not only influence operation, also might deviate from, thereby and fail in time to handle to form and be fastenedly connected mass defect and cause potential safety hazard because of the part that bolt or screw have embedded connected sheet material originally.
Summary of the invention
The problem that the utility model will solve provides a kind of fastening piece that can prevent effectively that in rotation set nut process self from being deviate from, and especially being fit to is to need the rotation set nut just to accomplish bolt or the screw that connects operation.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of with the fastening piece of preventing deviating from function; Comprise the head 4 and bar portion 1 that are connected as a single entity; Bar portion is passed between the connected sheet material, and bar portion is provided with the screw thread that cooperates with nut, it is characterized in that: bar portion is provided with the groove 3 around bar portion in the position of closing on head.
Resist to deviate from effect for further strengthening, in the bar portion of said groove, also be provided with convexity 2 around bar portion away from a side of head.
Advantage and the good effect that the utlity model has are: adopt setting tool it to be embedded in the sheet material fastening piece squeeze bulb; Groove can play the filling of the excess stock that head extruding back produces when installing; Avoiding excess stock to be extruded into plate surface causes sheet material uneven; After making excess stock flow to groove again the performance that resists to deviate from of fastening piece is improved, the convexity of groove front then plays leading role and strengthens anti-release ability, has improved operating efficiency; Prevent fastening piece in operation because of vibration causes getting loose, reduced mass defect and avoided potential safety hazard.Can be applicable to the position that small space or box house space etc. are difficult to use riveting gun.

Embodiment
As shown in Figure 1; The described fastening piece of the utility model no matter be bolt also or screw, all be to have a head 4 and bar portion 1 that is connected as a single entity, along on the bar portion y direction; The area of contour of head is greater than the area of contour of bar portion; The optimum shape of bar portion is cylindrical, and bar portion can entire body have screw thread, also can be that front end has screw thread; When the top of bar portion front end is provided with tip, be exactly the pattern of usually said screw, tip helps realizing the self tapping operation.
Head can be in hexagon head, square toes, T shape head, oval head, socket cap, round end, coiled hair, countersunk head or the countersunk raised head a kind of, but be not limited to above-mentioned these several kinds of patterns.And head also can be provided with the groove that the setting tool that conveniently uses similar screw-driver and so on makes the different shape of its rotation, such as cross or yi word pattern groove.
Tip also can be provided with screw thread, and the screw thread on the tip can continue with the screw thread of bar portion mutually.
The maximum characteristics of the utility model are that bar portion is provided with the groove 3 around bar portion in the position of closing on head.
The working procedure of this instance: use setting tool that sheet material is pre-installed earlier; Promptly under the pressure effect of setting tool, the fastening piece of the utility model is squeezed in the sheet material; The projecting teeth of fastener head below also is extruded into plate surface under pressure; And then bar portion opposite side exposed the part rotation set nut of sheet material; The filling of the excess stock that head extruding back produced when groove can play and install is avoided excess stock to be extruded into plate surface and is caused sheet material uneven, the performance that resists to deviate from of fastening piece is improved after making excess stock flow to groove again; The convexity of groove front then plays leading role and strengthens anti-release ability; A part of having avoided fastening piece (bolt or screw) to embed connected sheet material is originally deviate from, and has improved operating efficiency, thereby and has avoided being fastenedly connected the potential safety hazard that mass defect causes.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
