Abstract
The invention relates to a connection structure of a pipe, which comprises a connecting frame, wherein a lug is extended from the connecting frame into a pipe; a sliding rail climbing from the inside to the outside is arranged on the lug; a sliding block is arranged on the sliding rail; a draw rod movably penetrates through the connecting frame; the tail end of the draw rod is connected with the sliding block; a locking mechanism is arranged between the connecting frame and the draw rod; in the locking mechanism, one end of the draw rod is in threaded connection with the sliding block, a buckling head is arranged at the other end of the draw rod, and the buckling head is buckled with the connecting frame; and the shape of the contact surface between the sliding block and the pipe is matched with the shape of the surface of the inner wall of the pipe. By adopting the technical scheme, the sliding block can be pulled by the draw rod to climb along the lug until the lug generates tension force on the pipe, thereby realizing connection; the connection structure needs neither to damage the pipe body nor to rotate the pipe, and can keep very good rigidity after connection.
Description
Technical field:
The present invention relates to a kind of linkage structure of tubing.
Background technique:
Tubing is coupled together and require the joint to have certain intensity, traditional Placement is to adopt bolts and nuts to screw needs are refuted the tubing that connects to couple together, perhaps connecting the mode of tubing by screw-thread fit realizes refuting and connects, 1. the mode shortcoming that adopts screw bolt and nut to be connected is: can destroy body, the tubing pressurized is easy to generate to be out of shape to be provided with and breaks when screwing; 2. the mode by screw-thread fit realizes that the shortcoming that tubing connects is: do not allow under the situation of tubing rotation for some structure or occasion, the screw-thread fit ways of connecting just can not realize.
Summary of the invention:
The objective of the invention is in order to overcome the shortcoming of above-mentioned prior art, provide a kind of simple in structure, need not destroy body, adaptable pipe connecting structure.
For achieving the above object, technological scheme provided by the invention is: a kind of linkage structure of tubing, include link press span, link press span is extended with the tongue platform in tubing, this tongue platform is provided with the slide rail that climbs from inside to outside, and slide rail is provided with slide block, and pull bar has been passed in activity on link press span, the end of pull bar is connected with slide block, is provided with locking mechanism between link press span and the pull bar.
Described locking mechanism is that an end of pull bar becomes to be threaded with slide block, and the other end is provided with discount, discount and link press span snapping.
The surface configuration that contacts with tubing of slide block and the surface configuration of pipe material inner wall are complementary.
After adopting technique scheme, utilize pull bar pulling slide block to climb, up to the tension force of tongue platform generation to tubing along the tongue platform, thereby realize connecting, this linkage structure neither needs to destroy body, does not also need tubing to rotate, and connects the extraordinary rigidity of back maintenance.

Embodiment:
Now elaborate the present invention in conjunction with the accompanying drawings:
Embodiment one
The tubing 1 of present embodiment is square tubular, as Fig. 1～shown in Figure 4, its linkage structure includes link press span 2, link press span 2 is a square bearer, square link press span 2 is provided with fastener 3, be processed with button hole 4 on the fastener 3, on square link press span 2, be provided with the tongue platform 5 that in tubing 1, extends, on a side side of this tongue platform 5, be provided with the slide rail 6 that climbs from inside to outside, slide rail 6 is provided with a slide block 7, is processed with the inclined-plane 73 that cooperates with slide rail 6 on the slide block 7, and the surface that contacts with tubing 1 of slide block 7 is the plane, and this plane is provided with anti-skidding line 8, correspondingly the surface of tubing 1 inwall also is the plane, and bolt 9 has been passed in activity on link press span 2, and the discount 91 of bolt 9 cooperates snapping with the button hole 4 of fastener 3, be fixed with nut 10 on slide block 7, the thread section 92 of bolt 9 cooperates with nut 10.
During connection, tongue platform 5 and slide block 7 are filled in the tubing 1, and the turn bolt 9 then, and bolt 9 pulling slide blocks 7 outwards slide along tongue platform slide rail 6 and climb, until withstanding tubing 1 outer wall, if further turn bolt 9, slide block 7 and tongue platform 5 can produce the tension force to tubing 1, at this moment, slide block 7, tongue platform 5 and tubing 1 will be fixed together, add under the effect of screw thread and fastener 3, bolt 9 fixes up link press span 2 and slide block 7, realizes that finally link press span 2 and tubing 1 are fixed together.Realize the connection of tubing, as long as adopt said structure and step to couple together just passable to other tubing and link press span 2 at other end face of link press span 2.
Embodiment two
Compare with embodiment one, the difference of present embodiment is that the bilateral symmetry face at tongue platform 5 is provided with the slide rail 6 that climbs from inside to outside respectively, corresponding configuration two slide blocks 7 on tongue platform 5, nut 10 is arranged on the terminal of two slide blocks 7 and is close to two slide blocks 7 simultaneously, nut 10 is processed with first plane of inclination 11 and second plane of inclination 12 of working in coordination respectively with slide block 7, improve the stability that slide block 7 slides and climbs with this, in addition, the end of two slide blocks 7 is respectively arranged with and colludes first hook portion 71 and second hook portion 72 of closing mutually, during assembling, close by colluding of first hook portion 71 and second hook portion 72 and can prevent that the slide block that is in the bottom from dropping, the convenient installation is as Fig. 5～shown in Figure 7.
During connection, turn bolt 9 makes nut 10 promote two slide blocks 7 and does to slide synchronously the action of climbing, and under the leading role of slide rail 6, produces the tension force to tubing 1 until two slide blocks 7.
The tubing of the technical program also can be pipe, five cornues, hexagonal pipe etc., the corresponding shape of mating with pipe material inner wall that is processed into of the face that cooperates with pipe material inner wall of slide block.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
