Abstract
The utility model relates to a bolt capable of avoiding losing. The bolt comprises a thread section and a polish rod section, wherein the polish rod section is movably connected with the thread section, and a whole of the polish rod section is T-shaped. The external diameter of the thread section is slightly larger than that of the polish rod section. The bolt can avoid losing.
Description
Technical field
The utility model relates to a kind of five metals, relates in particular to a kind of screw of losing avoided.
Background technique
When two parts link together with screw, if in the time of two parts need to need to being separated, need turn on screw.And when screw was separated from one of them part, two parts were just separated.But in the operating process of reality, uncontrollable screw only breaks away from one of them part and does not break away from the another one part.So just exist the screw that is separated from two parts to keep properly, otherwise screw is easily lost.
The model utility content
In order to solve the above-mentioned technical problem that exists in background technique, the utility model provides a kind of screw of losing avoided.
Technical solution of the present utility model is: the utility model provides a kind of screw of losing avoided, and its special support is: the described screw of avoiding losing comprises thread section and is T-shaped polished rod section with integral body that thread section is flexibly connected; The external diameter of described thread section is slightly larger than the external diameter of polished rod section.
Above-mentioned polished rod section is provided with endoporus along its axial direction; Described thread section stretches in the endoporus of polished rod section and is flexibly connected with the polished rod section.
Be provided with internal thread in above-mentioned endoporus, described thread section stretches into the endoporus of polished rod section and is connected with the polished rod section by internal thread.
Above-mentioned thread section stretches in endoporus and partly is provided with outside thread, and described thread section stretches into the endoporus of polished rod section and is connected with the polished rod section by outside thread.
The utility model has the advantages that:
The utility model is divided into thread section and polished rod section two-part with traditional integrated screw, thread section inserts in the polished rod section and links together by the internal thread that is arranged on the polished rod section, in use, at first thread section and polished rod section are separated, the first part is inserted polished rod Duan Shanghou thread section and polished rod section are linked together, screw just can't withdraw from the screw hole on the first part; Thread section is stretched in the second part and be threaded with the second part, the utility model can avoid screw to lose, and is very easy to use.
Description of drawings
Fig. 1 is the structural representation of avoiding the screw lost provided by the utility model;
Fig. 2 is that the utility model uses state reference map;
Wherein:
The 1-thread section; 2-polished rod section.
Embodiment
Referring to Fig. 1, the utility model provides a kind of screw of losing avoided, and this screw comprises thread section 1 and polished rod section 2 two-part, and thread section 1 inserts in polished rod section 2 and is movably connected with polished rod section 2.
Be provided with internal thread in endoporus, thread section 1 stretches into the endoporus of polished rod section 2 and is connected with polished rod section 2 by internal thread.
Thread section 1 stretches in endoporus and partly is provided with outside thread, and thread section 1 stretches into the endoporus of polished rod section 2 and is connected with polished rod section 2 by outside thread.
Referring to Fig. 2, at first the utility model separates thread section 1 and polished rod section 2, after on the first part insertion polished rod section 2, thread section 1 and polished rod section 2 is linked together, and screw just can't withdraw from the screw hole on the first part; Namely the utility model is arranged on the first part all the time, has directly avoided the loss of screw.
The utility model then stretches into thread section 1 in the second part and is threaded with the second part in use, and the utility model can avoid screw to lose, and is very easy to use.
The size of screw thread and the coupling of the tapped hole on part, the diameter of polished rod should be less than the bottom outlet of part upper screwed hole.
