Abstract
The invention relates to a captive screw structure. The captive screw structure comprises a fixed screw and a riveting piece sleeving the fixed screw, wherein the fixed screw comprises a screw head part and a screw rod part; a screw thread which is protruded outwards is arranged on the screw rod part; a through hole is formed in the middle part of the riveting piece to allow the screw rod part to pass through; a ring-shaped stop block which is protruded inwards is arranged at the end part, close to the screw head part, of the through hole; the internal diameter of the ring-shaped stop block is smaller than the external diameter of the screw thread and larger than the diameter of the screw rod part. With adoption of the structure, the captive screw structure is simple in combined structure, short in time for combination, capable of improving the production efficiency of the product, small in size, and capable of reducing the production cost; the captive screw structure adopts the flange riveting structure instead of spline tooth riveting, so that the captive screw structure cannot destroy the panel structure or influence the use functions of the panel.
Description
Technical field
The present invention relates to five metals manufacturing technology industry, especially relate to a kind of captive screw structure.
Background technique
At present, make in industry at five metals, there is a kind of captive screw structure, can ensure that in unloading process screw and riveted part can not depart from, easy to use, this bolt structure is mainly socketed on screw by riveted part, between screw and riveted part, be provided with spring, screw is provided with annular knurl, by turning the object that annular knurl realizes connecting, but its complex structure of this screw, and the assembly time is relatively long, riveted part adopts flower tooth to carry out riveted, after flower tooth is entered aluminium sheet by riveting, the structure of sheet material can be destroyed, affect using function.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of structure and simply saves time and the captive screw structure can not destroying sheet material.
The present invention solves the technological scheme that its technical problem takes: a kind of captive screw structure, comprise set screw and socket and the riveted part of movement on set screw, described set screw comprises screw head and screw rod portion, described screw rod portion is provided with outwardly screw thread, be provided with in the middle part of described riveted part and pass for screw rod portion through hole, be provided with inwardly protruded ring-type limiting stopper through hole near the end of screw head described, the internal diameter of described ring-type limiting stopper is less than the external diameter of screw thread and is greater than the diameter in screw rod portion.
Further, in order to sheet material can be protected to exempt from destruction, described riveted part turns over riveting limit away from the protruding ring-type in end of screw head.
Further, in order to protect the screw thread in screw rod portion to preserve from, described ring-type limiting stopper outer wall and riveted part axis are 45 ° of angles, and the inwall of ring-type limiting stopper and riveted part axis are 60 ° of angles.
Concrete further, described screw head is provided with interior plum blossom band post.
Concrete further, described screw head is provided with straight groove or cross recess.
The invention has the beneficial effects as follows: after have employed said structure, composite structure is simple, and the time used is few, the manufacturing efficiency of product can be improved, small volume, reduce cost of production, do not adopt colored tooth to rivet and riveting knot structure is turned in employing, the structure of sheet material can not be destroyed, its using function can not be affected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of riveted part of the present invention.
In figure: 1, riveted part; 2, set screw; 11, ring-type limiting stopper; 12, ring-type turns over riveting limit; 21, interior plum blossom band post; 22, screw head; 23, screw rod portion; 24, screw thread.
Embodiment
Below in conjunction with accompanying drawing, the present invention is explained in detail.
A kind of captive screw structure as depicted in figs. 1 and 2, comprise set screw 2 and be socketed and the riveted part 1 of movement on set screw 2, described set screw 2 comprises screw head 22 and screw rod portion 23, described screw rod portion 23 is provided with outwardly screw thread 24, be provided with in the middle part of described riveted part 1 and pass for screw rod portion 23 through hole, inwardly protruded ring-type limiting stopper 11 is provided with through hole near the end of screw head 22 described, the internal diameter of described ring-type limiting stopper 11 is less than the external diameter of screw thread 24 and is greater than the diameter in screw rod portion 23, can ensure that set screw 2 can not drop from riveted part 1.
Riveted part 1 turns over riveting limit 12 away from the protruding ring-type in end of screw head 22, adopts and turns over the destruction of riveting knot structure minimizing to sheet material, can not affect the using function of sheet material.
Ring-type limiting stopper 11 outer wall and riveted part 1 axis are 45 ° of angles, and the inwall of ring-type limiting stopper 11 and riveted part 1 axis are 60 ° of angles, reduce the destruction of ring-type limiting stopper 11 double thread 24, increase the working life of captive screw structure.
Described screw head 22 is provided with interior plum blossom band post 21, realizes anti-theft feature; Described screw head 22 is provided with straight groove or cross recess.
The using process of captive screw structure: first, turning over riveting limit 12 by ring-type is riveted on sheet material by riveted part 1, the length of turning over riveting limit is lower than sheet material 0.2mm after riveted joint, after riveted joint outside not outstanding sheet material, tightening operation is carried out by the screw thread 24 in set screw bar portion 23, when dismounting, only need set screw 2 to unclamp, because the ring-type limiting stopper 11 on riveted part 1 can ensure that set screw 2 can not come off.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
