Abstract
The invention provides a straight joint and relates to the technical field of hydraulic pipe connection. The straight joint is a four-way pipe joint and comprises a body. The body comprises four pipe joint bodies which are evenly arranged. The end side of each pipe joint body is provided with connecting threads. The straight joint is characterized in that the body further comprises fixing lugs which are evenly arranged between the pipe joint bodies at intervals, and each fixing connecting hole is formed in one corresponding fixing lug. The straight joint is reasonable in structure, convenient to use, high in stability, capable of guaranteeing that a connecting pipe is not prone to sliding off, safe and reliable.
Description
Technical field:
The present invention relates to hydraulic tubing interconnection technique field, specifically a kind of straight coupling.
Background technique:
Pipe joint is hydraulic pressure term, is connecting pipeline or pipeline is contained in to the part on hydraulic element in hydraulic system, and this is a kind of general name of the link that can install and remove in fluid passage.Existing straight coupling body exterior is all the form that is set to cylinder or conical surface, like this when hydraulic tubing connects, have especially in the situation of liquid, in twisting dead process, be difficult to fix, easily skid, has plenty of the structure of being convenient to tighten that is provided with nut type in an end of straight coupling, but the screwing structure of this set in end increases straight coupling difficulty of processing, or operation increases, be not easy to processing, in the pipeline of existing straight coupling, be not provided with in addition ladder, like this in long using process, easily there is the situation of leakage liquid.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of being convenient to tighten, and easily processes, and is not easy to occur the straight coupling of leakage liquid.
The technical problem solving adopts following technological scheme:
A kind of straight coupling, comprise body, described body central position is provided with pipeline, it is characterized in that: one end of described pipeline is provided with 2～3 ladders, inner side or the arranged outside of the other end of described pipeline have connecting thread, and the cross section external frame in middle part of described body becomes regular polygon.
Described regular polygon is positive 6～12 limit shapes.Make regular polygon be unlikely to too complicated, thereby reduce the difficulty of processing.
The regular polygon profile of outside of the present invention is to be convenient to of the present invention tightening, and in pipeline, one end arranges ladder, makes the not same liquid that exposes of the present invention.
The invention has the beneficial effects as follows: the present invention is rational in infrastructure, easy to use, be convenient to tighten, easily processing, is not easy to occur leakage liquid.

Fig. 1 is the main TV structure schematic diagram of the embodiment of the present invention one.
Fig. 2 is the left TV structure schematic diagram of the embodiment of the present invention one.
Fig. 3 is the main TV structure schematic diagram of the embodiment of the present invention two.
Fig. 4 is the left TV structure schematic diagram of the embodiment of the present invention two.
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Specific embodiment one:
As shown in Figure 1, 2, a kind of straight coupling, comprises body, body central position is provided with pipeline 1, and one end of pipeline 1 is provided with 3 ladders 2, and the other end of pipeline 1 is provided with connecting thread 3, connecting thread 3 is outside thread, and the cross section external frame in middle part of body becomes positive 6 polygonals.
Specific embodiment two:
As shown in Figure 3,4, a kind of straight coupling, comprises body, body central position is provided with pipeline 1, and one end of pipeline 1 is provided with 3 ladders 2, and the other end of pipeline 1 is provided with connecting thread 3, connecting thread 3 is internal thread, and the cross section external frame in middle part of body becomes positive 8 polygonals.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (2)
1. a straight coupling, comprise body, described body central position is provided with pipeline, it is characterized in that: one end of described pipeline is provided with 2～3 ladders, inner side or the arranged outside of the other end of described pipeline have connecting thread, and the cross section external frame in middle part of described body becomes regular polygon.
2. a kind of straight coupling according to claim 1, is characterized in that: described regular polygon is positive 6～12 limit shapes.
