Abstract
The utility model discloses a connecting device of multi-segment bars, which comprises an upper connecting piece (5) which is tightly matched with a hollow pipe body of an upper connecting bar (6) and a lower connecting piece (4) which is tightly matched with a hollow pipe body of a lower connecting bar (2), wherein a bolt (7) which is integrally connected is arranged on the upper connecting piece (5), a threaded hole which is matched with the bolt (7) is arranged on the lower connecting piece (4), the end surface of the upper connecting piece (5) is provided with a concave conical groove (52), a convex cone (41) is arranged on the end surface of the lower connecting piece (4), and the convex cone (41) is matched with the concave conical groove (52). With the structure, the connecting device solves the shortcomings that multi-segment bars have bad connecting intensity, and can not be kept on the same line. The utility model has the advantages of simple and compact structure, convenient processing and assembly, excellent concentricity, reliable use, long service span and the like.
Description
Technical field
The utility model relates to a kind of connection set, particularly a kind of fixing device that is used for connection between each joint of more piece bar.
Background technique
As everyone knows, people often use elongated bar class instrument in daily life, as mop bar, clothes airing rod or the like, for the ease of packing, transportation, storage and collection, usually elongated straight-bar is resolved into more piece, the connection set that matches is set between bar and bar, connects into stock by connection set again during use.At present the more piece rod connecting device generally comprise with the upper connector of the hollow body close-fitting of last connecting rod, with the following link of the hollow body close-fitting of lower link, upper connector is provided with the bolt that is connected as a single entity, following link is provided with the screw that matches with bolt.The deficiency that this connection set exists: the one, the more piece bar can not remain on the same straight line after connecting into straight-bar, and concentricity is poor; The 2nd, because connection set generally adopts plastics to make, force bearing point concentrates on again on the bolt, ruptures easily in the joint, and working life is short; The 3rd, connection set is loosening easily, is affected during use.The deficiency of above-mentioned existence has become a difficult problem in the industry, does not have ideal method to remedy above-mentioned deficiency so far as yet.
Summary of the invention
For overcoming existing connection set above shortcomings, the purpose of this utility model provide a kind of simple and compact for structure, processing is easy to assembly, good concentricity, use is reliable, the life-span is long more piece rod connecting device.
The technological scheme that its technical problem that solves the utility model adopts, it comprise with the upper connector of the hollow body close-fitting of last connecting rod, with the following link of the hollow body close-fitting of lower link, upper connector is provided with the bolt that is connected as a single entity, following link is provided with the screw that matches with bolt, the end face of described upper connector is provided with recessed cone tank, the end face of following link is provided with the cone of projection, and the cone of projection and recessed cone tank are complementary.
Further preferred version of the present utility model, correspondence is provided with and tops bar and get out of a predicament or an embarrassing situation on described upper connector and the following link.
Further preferred version of the present utility model, the described connecting rod of going up is provided with a plurality of fixedly stuck points with the circumferential surface that upper connector and lower link match with following link.
After adopting said structure, when the assembling of more piece bar is used, be bolted to down on the screw on the link, the cone of projection cooperates with recessed cone tank, the end face coupling of the end face of upper connector and following link; Following advantage is arranged: the one, because cone cooperates with cone tank, can remain on the same straight line after making the more piece bar connect into straight-bar; The 2nd, connection set is stressed comparatively reasonable, and except that bolt strained, cone and cone tank are also simultaneously stressed, and force bearing point is many, and stress surface is big, has overcome the joint deficiency of fracture easily, long service life; The 3rd, even connection set is loosening to some extent, do not influence usability yet.
