Specific embodiment

Specific embodiment of the present utility model is further described with reference to the accompanying drawing.

In Fig. 1 ~ 9, including node pedestal 1, internal thread hole 1.1, bar diameter adjuster 2, cylindrical body 2.1, bar diameter adjuster connect It connects end 2.2, limited step 2.3, slot 2.4, strip protrusion 2.5, linear grooves 2.6, locking teeth 2.7, locking device 3, close up Portion 3.1 etc..

As shown in Fig. 1 ~ 9, the utility model is a kind of trellis supports node connecting structure, including node pedestal 1, the section Point pedestal 1 be equipped at least one axially through internal thread hole 1.1, the both ends of internal thread hole 1.1 are respectively charged into mutual cooperation The bar diameter adjuster 2 and locking device 3 of effect, when locking device 3 screws, the working end internal diameter of bar diameter adjuster 2 is accordingly shunk, The axial outer end of 2.3 axial limiting of step that the axial inner ends of bar diameter adjuster 2 are arranged by its surface, bar diameter adjuster 2 is logical Cross 3 axial limiting of locking device.

In concrete practice, the mutual positional relationship of the multiple internal thread holes 1.1 being arranged on node pedestal 1 can root It is needed according to concrete condition, carries out flexible setting, can be mutually perpendicular to, but be not limited only to vertical.

Fig. 3 gives one of embodiment of node pedestal 1, the scheme of the embodiment are as follows: phase on node pedestal 1 Internal thread hole 1.1 there are three mutually vertically setting.This is a kind of more common embodiment, using this embodiment, Ke Yishi The frame body in existing tri- directions frame X, Y, Z is set up.

Shown in Fig. 4 ~ 7, the outer end face of bar diameter adjuster 2 is equipped with several slots 2.4 axially extended, two neighboring slot Locking teeth 2.7 is formed between 2.4.When bar diameter 2 radial force of adjuster, can shrink to reduce internal diameter and reach fastening support bar Effect.

Locking teeth 2.7 is equipped with lateral strip protrusion 2.5, in order to the transverse concave groove on support rod to be connect It matches, achievees the purpose that prevent axial movement.

Bar diameter adjuster 2 includes axially extending cylindrical body 2.1, and 2.1 surface of cylindrical body is equipped with limited step 2.3, limit The radial protrusion abutting contact of 2.3 inner face of step and the setting of 1.1 inner wall of internal thread hole, the outer end face and lock of limited step 2.3 The inner face abutting contact of tight device 3.In specific production process, limited step 2.3 has one fixed width, limited step 2.3 Playing the role of one direction prevents axial float.

The inner hole of bar diameter adjuster 2 and the connecting pin outer surface of support rod to be connected are consistent.Specifically, bar diameter is adjusted The internal via shape of device connecting pin 2.2 can be rectangle, polygon, circle etc..It is circle for 2.2 inner hole of bar diameter adjuster connecting pin The case where shape, is equipped with the linear grooves 2.6 axially extended in the inner wall of each locking teeth 2.7, in order to it is to be connect Strip protrusion on support rod matches, and support rod is avoided to rotate.

Shown in Fig. 9, locking device 3 is the tube-in-tube structure with flange, and hub internal bore outer end is closing in portion 3.1, sleeve table The external screw thread in face and internal thread hole 1.1 are in mating connection.

Circumference of flange surface is laid with the non-slip groove radially extended.By the way that non-slip groove is arranged, may be implemented rotating When locking device 3, effective increasing friction force can be convenient and quickly screw.

The utility model product may be used as frame, flower stand, when for frame, in flower stand when, plastics can be used Material can also use metal material；The utility model product can also be applied in building scaffold, when in scaffold When, it is made of metal material.
