Abstract
The utility model relates to an arc-thread combination connecting structure without screw threads, which comprises a barrel-shaped connecting rod, wherein the end of the barrel-shaped connecting rod is equipped with a column-shaped connector, one end of the connector is an inserting end, and the other end is a connecting end, the middle portion of the connector is equipped with a convex skirt, the outer wall side of the end of the barrel-shaped connecting rod is sleeved with a lock cap, and the top of the lock cap is equipped with a connector through hole. The arc-thread combination connecting structure without screw threads can enable the shearing force of the rod to be smallest and enable the extrusion force and the interlayer cohesive force to be largest, thereby effectively increasing the failure tension of the combination rod, and enabling the failure tension to be increased to the two-thirds of the strength of the combination rod.
Description
Technical field
The utility model belongs to the structure connection area, relates to a kind of rod member linkage structure, especially a kind of without screw thread, circular arc screw thread combined connecting structure.
Background technique
The rod member that composite pipe is made, between bar and bar, be connected or bar when being connected with other metal rod, mostly adopt single regular screw threads mode to connect, this Placement, when rod member is stressed, the threaded connection place is subjected to the stress maximum, and single engage thread often connects rod member and do not reach maximum and bear collapsing force, and the intensity of threaded connection place is equivalent to three of the own intensity of coincidence tube/once destroying in advance.Cause the tension strength of composite pipe rod member fully not to be utilized.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of without screw thread and circular arc screw thread combined connecting structure are provided, be that inner core adopts without screw thread, external diameter adopts the circular arc screw thread, when goods are stressed, the shearing force minimum that goods are subjected to, the cohesive force maximum of extruding force and interlayer, thereby the destruction pulling force of goods is doubled on the basis of existing interconnection technique, reach 2/3rds of the own intensity of composite tubular article.
The purpose of this utility model solves by the following technical programs:
This kind without screw thread, circular arc screw thread combined connecting structure, comprise the tubular connecting rod, it is characterized in that: described tubular connecting rod termination is inserted with the column connecting head, the first end of described connection is a bayonet end, the other end is the metal connecting end, described connecting head middle part is provided with protruding skirt, and described tubular connecting rod termination outer wall side is arranged with lock nut, and described lock nut crown offers the connecting head perforation.
The above-mentioned bayonet end sidewall of stating connecting head is processed with reticulate pattern, and described bayonet end head is processed into the fillet shape.
The metal connecting end sidewall of above-mentioned connecting head is smooth cylinder, and described metal connecting end head is processed with chamfering.
Above-mentioned metal connecting end is processed with radially attachment hole, axial notch or axial pass trough.
Above-mentioned tubular connecting rod and described lock nut cooperatively interact with the circular arc engage thread.
The shearing force minimum that without screw thread of the present utility model, circular arc screw thread combined connecting structure can make rod member be subjected to, the cohesive force maximum of extruding force and interlayer, thereby effectively raise the destruction pulling force of compound rod member, make it destroy pulling force and bring up to 2/3rds of own intensity.

Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1 and Fig. 2, this without screw thread, circular arc screw thread combined connecting structure, comprise tubular connecting rod 1, described tubular connecting rod 1 termination is inserted with column connecting head 3, and as shown in Figure 3, connecting head 3 one ends are bayonet end 7, the other end is a metal connecting end 8, connecting head 3 middle parts are provided with protruding skirt 6, and described tubular connecting rod 1 termination outer wall side is arranged with lock nut 2 (as Fig. 4), and described lock nut 2 crowns offer connecting head perforation 4.
According to above description to the utility model structure, this without screw thread, circular arc screw thread combined connecting structure adopt special thread to add the mode of grafting without screw thread, the bayonet end wall of its connecting head 3 is processed with reticulate pattern, increase frictional force, in order to the inwall that is connected rod member 1 with the tubular connection that matches, and bayonet end 7 heads are processed into the fillet shape, just can be easy to insert tubular so when mounted and connect rod member 1.
The metal connecting end 8 of connecting head 3 can be designed to different shape according to the needs of fastening, be smooth cylinder as metal connecting end 8 sidewalls among Fig. 1, and its head is processed into chamfering with convenient assembling and disassembling.On described metal connecting end 8, can process radially attachment hole 9 or axial pass trough 10 as required.
Tubular connecting rod 1 cooperatively interacts in circular arc screw thread 5 modes with described lock nut 2 and is connected, and is processed with circular arc screw thread 5 at the corresponding lock nut of the end of tubular connecting rod 1 outer wall.
During the utility model assembling, bayonet end 7 with connecting head 3 inserts tubular connecting rod 1 is stuck in tubular connecting rod 1 until the protruding skirt 6 of connecting head 3 termination earlier, again lock nut is passed the metal connecting end 8 of connecting head through connecting head perforation 4, and it is supporting to tubular connecting rod 1 by circular arc screw thread 5, this moment, lock nut will be locked protruding skirt 6, thereby connecting head 3 is fastening, make connecting rod 1, connecting head 3 fastening one.
