Abstract
The invention provides a fastening device which mainly comprises nuts and screw rods, wherein one end of each screw rod is designed into a pagoda shape with notches, and external screw threads are formed at the other end of each screw rod. For first use, a small amount of instantly hardening glue is injected into plastic screw holes, pagoda ends of the screw rods are inserted into the plastic screw holes, an injection molding piece is assembled, and then the nuts are screwed at screw thread ends of the screw rods. For assembly and disassembly, only the nuts instead of the screw rods are required to be assembled and disassembled. The fastening device can be used for replacing the traditional screw, and has the advantages of simple structure, low cost, convenience in disassembly and assembly and long service life.
Description
Technical field
The present invention relates to mechanical basic part, be specially a kind of long lifetime securing means being used for replacing conventional screw.
Background technique
In tratitional technology, tightened together by metallic screw precession plastics screw between moulding.The securing means that traditional metallic screw and plastics screw form, after dismounting several times, there will be the phenomenon of the wearing and tearing of plastics screw internal thread, running, causes screw to be installed insecure, do not have fastening effect.Such as, adopt the toner cartridge of conventional screw fastening means, when carrying out circular regeneration, often occur that plastics screw internal thread damages phenomenon, cause the loss that whole moulding is discarded.
Summary of the invention
For the deficiency of the securing means that conventional metals screw and plastics screw form, the present invention puts forward a kind of long lifetime securing means being used for replacing conventional screw.
This securing means is primarily of nut and screw rod composition, wherein one end of screw rod is designed to pagoda shape, rugosity just equals the internal diameter of plastics screw, and tower layer is more than two-layer, the edge of every layer is all with jagged, prevent from screw rod to be embedded in after on moulding coming off, rotate, the other end, with outside thread, can coordinate with nut inner thread.
When using first, in plastics screw, first inject a little ebonite instantaneously, the pagoda end of screw rod is injected plastics screw, after moment ebonite sclerosis, screw rod has just been embedded in plastics screw.Then assemble moulding, nut is spun on screw flight end, this completes the assembling of moulding.Again during dismounting moulding, only need dismounting nut, without dismounting screw rod.
Securing means proposed by the invention has that structure is simple, the advantage of low cost, easy accessibility, long service life.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of screw rod.
Fig. 2 is the schematic diagram of moulding one.
Fig. 3 is the schematic diagram that screw rod is embedded in plastics screw.
Fig. 4 is the schematic diagram after assembling moulding two.
Fig. 5 is the schematic diagram after mounting nuts.
As figure, 1 nut, 2 screw rods, 21 pagoda ends, 22 threaded end, 23 breach, 3 moulding one, 31 plastics screws, 4 mouldings two.
Embodiment
This securing means is primarily of nut (1) and screw rod (2) composition, as shown in Figure 1, one end of screw rod (2) is designed to the pagoda shape being with breach (23), prevent from screw rod (2) to be embedded in after on moulding coming off, rotate, this end is called pagoda end (21), the other end, with outside thread, can coordinate with nut inner thread, and this end is called threaded end (22).
As shown in Figure 2, on moulding one (3) with plastics screw (31).
As shown in Figure 3, when using first, in plastics screw (31), first inject a little ebonite instantaneously, the pagoda end (21) of screw rod (2) is injected plastics screw (31), after moment ebonite sclerosis, screw rod (2) has just been embedded in plastics screw (31).Then, as shown in Figure 4, assembling moulding two (4), as shown in Figure 5, is spun on nut (1) threaded end (22) of screw rod (2), this completes the assembling of moulding.
Claims (1)
1. a securing means, this securing means is primarily of nut and screw rod composition, it is characterized in that: one end of screw rod is designed to pagoda shape, rugosity just equals the internal diameter of plastics screw, and tower layer is more than two-layer, the edge of every layer is all with jagged, prevents from screw rod to be embedded in after on moulding coming off, rotates, the other end, with outside thread, can coordinate with nut inner thread.
