Abstract
The utility model discloses an inserting-connection-type pipe structure which comprises a hollow thin-wall pipe. The outer surface of the pipe is at least provided with two axially-arranged first limiting grooves with trapezoidal sections, fixing holes are arranged at two ends of each first limiting groove, and an axially-arranged second limiting groove with a hemispherical section is further arranged on the outer surface of the pipe and is slightly deeper than the first limiting grooves. The inserting-connection-type pipe structure can realize mutual inserting-connection fixing, the pipe after inserting connection is ensured not to relatively rotate by the first limiting grooves and the second limiting groove arranged on the surface of the pipe, and connecting and fixing are realized through the fixing holes which are matched with one another after the lower end of a small-diameter pipe is inserted into the upper end of a large-diameter pipe, so that the fixing mode is reliable; the second limiting groove is slightly deeper than the first limiting grooves, and fixing in the peripheral direction is enhanced due to difference in depth of the limiting grooves; a circular-arc-shaped clamping groove is arranged on the outer surface of the pipe, and a cylindrical inserting strip can be inserted into the clamping groove to be connected with other parts, so that usage range of the pipe is expanded.
Description
Technical field
The utility model relates to tubing and manufactures field, is specifically related to a kind of plug-in type pipe structure.
Background technology
?tubing has the advantages such as light weight, axial strength is high, overlap joint is convenient, the support bar of the simple and easy shelter such as tent, mat shelter adopts tubing to be spliced more, between tubing, by welding or adapter sleeve, connect, but the tubing of welding is fixing reliable non-dismountable, after welding, purposes is subject to great restriction, adopts the tubing that adapter sleeve connects can free disassembly and assembly, uses flexibly, but splicing is wasted time and energy, use inconvenient.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of plug-in type pipe structure, fixing reliable, easy to assembly quick.
The utility model is achieved through the following technical solutions:
A kind of plug-in type pipe structure, the thin-wall pipes that comprises hollow, the external surface of described tubing is at least provided with two cross sections of axially offering and is the first trapezoidal stopper slot, the two ends of described the first stopper slot are provided with fixing hole, the external surface of described tubing is also provided with the second stopper slot of a cross section semicircular in shape of axially offering, and described the second stopper slot is slightly deeper than described the first stopper slot.
The further improvement project of the utility model is, the width of rebate of described the first stopper slot is greater than bottom land width, and described fixed hole position is in the bottom land of described the first stopper slot and apart from the end face 30-80mm of place end.
The utility model further improvement project is, a side of described the second stopper slot is provided with the draw-in groove that cross section is more than half circular arc, and the radian of described draw-in groove opening is not more than π/6.
The utility model further improvement project is that described the second stopper slot, draw-in groove are between adjacent two the first stopper slots.
The utility model further improvement project is that described the first stopper slot, the second stopper slot, draw-in groove axially run through the upper and lower end face of described tubing and be parallel to each other.
The utility model further improvement project is, described the second stopper slot is identical with the degree of depth of described draw-in groove, and the degree of depth of described the first stopper slot, the second stopper slot, draw-in groove is no more than 1/5th of described tubing radius.
The utility model compared with prior art has the following advantages:
The utility model can be pegged graft fixing mutually, first, second stopper slot that is located at tube surfaces has guaranteed that the tubing after grafting can not relatively rotate, behind the upper end of path tubing lower end insertion large-diameter pipe material, by the fixing hole cooperatively interacting, be connected and fixed, fixed form is reliable.Wherein, the second stopper slot is slightly deeper than the first stopper slot, and the otherness of the stopper slot degree of depth has further been strengthened the fixing of circumferencial direction, is also provided with the draw-in groove of circular arc at the external surface of tubing, columniform cutting can be inserted in draw-in groove and is connected with miscellaneous part, has expanded the purposes of tubing.
Accompanying drawing explanation
Fig. 1 is the utility model end face structure schematic diagram.
The specific embodiment
A kind of plug-in type pipe structure as shown in Figure 1, the thin-wall pipes 1 that comprises hollow, the external surface of tubing 1 is provided with three cross sections of axially offering and is the first trapezoidal stopper slot 2, the width of rebate of the first stopper slot 2 is greater than bottom land width, the external surface of tubing 1 is also provided with the second stopper slot 4 of a cross section semicircular in shape of axially offering, the second stopper slot 4 is slightly deeper than described the first stopper slot 2, the groove depth of concrete is the second stopper slot 4 is 1.2 times of the first stopper slot 2 groove depths, because first, the second stopper slot 2, 4 there is tubing socket after can not produce relative rotation, the second stopper slot 4 of deepening has been strengthened limit function, guarantee the fixing of tubing circumferencial direction.
As shown in Figure 1, the two ends of the first stopper slot 2 are provided with fixing hole 3, and fixing hole 3 is positioned at the bottom land of the first stopper slot 2 and apart from the end face 30mm of place end, and the end tap bolt that small diameter tube inserts large-diameter pipe is through the fixing tubing of the fixing hole cooperatively interacting.
As shown in Figure 1, a side of the second stopper slot 4 is provided with the draw-in groove 5 that cross section is more than half circular arc, and the radian of draw-in groove 5 openings is π/6, and columniform cutting can be inserted in draw-in groove and is connected with miscellaneous part, has expanded the purposes of tubing.
In the present embodiment, the second stopper slot 4, draw-in groove 5 are between adjacent two the first stopper slots 2, and the first stopper slot 2, the second stopper slot 4, draw-in groove 5 axially run through the upper and lower end face of tubing 1 and be parallel to each other.The second stopper slot 4 is identical with the degree of depth of draw-in groove 5, and wherein, the degree of depth of the first stopper slot 2, the second stopper slot 4, draw-in groove 5 is no more than 1/5th of tubing 1 radius, can guarantee the intensity of tubing.
