Abstract
The utility model discloses a welding-free expansion type locking structure of a vertical rod. The welding-free expansion type locking structure of the vertical rod comprises a locking disc, wherein the vertical rod is arranged in the locking disc in a sleeved mode, the inner wall of the vertical rod is expanded to achieve locking after the vertical rod is arranged in the locking disc in the sleeved mode, a double-way connection pin is inserted into one end of the vertical rod and is connected with the vertical rod through a bolt, the locking disc comprises a cylindrical locking part, a circular groove is formed in the locking part, a reinforcing ring is arranged on the locking part through a plurality of spokes, and buckle holes are formed between every two adjacent spokes. The welding-free expansion type locking structure of the vertical rod solves the problems, in the prior art, that the strength of the vertical rod is not high and the disc can be deformed easily and has the advantages of being simple in structure, convenient to operate, low in weight, environmentally friendly, low in manufacturing cost and the like.
Description
Technical field
The utility model relates to indoor and outdoor finishing platform and Construction Formwork & Scaffold Technology field, is that a kind of vertical rod exempts to weld swollen type locking mechanism specifically.
Background technology
Disk vertical rod system is a kind of support of indoor and outdoor finishing extensive use, traditional disk vertical rod system all is welded by aluminum pipe and plate disk, because welding can produce larger impact to the intensity of pipe, thereby the whole system of having influence on, the plate disk is after being subject to strong external force, distortion can be produced, because being fixes with welding manner, the plate disk can't be changed after the distortion so.
The utility model content
The purpose of this utility model is to overcome the deficiency that above prior art exists, and provides that a kind of simple in structure, convenient operation, structure are light, environmental protection, vertical rod that cost of manufacture is low exempt to weld swollen type locking mechanism.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of vertical rod exempts to weld swollen type locking mechanism, comprise the locking disk, the locking disk is inserted in vertical rod, after the locking disk is inserted in vertical rod, by expansion vertical rod inside pipe wall, locked, two-way connecting pin inserts vertical rod one end, and two-way connecting pin and vertical rod are bolted.
As a kind of preferred structure, described locking disk comprises columniform tight lock part, and tight lock part offers annular groove, and tight lock part is provided with reinforcing ring by some spokes, between adjacent spoke, forms button hole.
In order to strengthen intensity, described spoke bottom is provided with reinforcing rib.
More firm in order to fix, offer through hole on described tight lock part sidewall, tight lock part is by through hole and vertical rod riveted joint.
As a kind of preferred structure, described button hole is 8, and spoke is 8.
For the ease of processing, the described locking disk structure that is formed in one.
Operating principle of the present utility model: a kind of vertical rod exempts to weld swollen type locking mechanism, comprises the locking disk, and the locking disk is inserted in vertical rod, after the locking disk is inserted in vertical rod, by expansion vertical rod inside pipe wall, locked, two-way connecting pin inserts vertical rod one end, and two-way connecting pin and vertical rod are bolted.The locking disk comprises columniform tight lock part, and tight lock part offers annular groove, and tight lock part is provided with reinforcing ring by some spokes, between adjacent spoke, forms button hole.
During practical operation, after vertical rod is inserted in to the locking disk, by expansion vertical rod inside pipe wall, vertical rod inside pipe wall after expansion is stuck in the annular groove of tight lock part, thereby realize exempting from weldering, the characteristics such as because do not need welding, have that convenient operation, structure are light, environmental protection, cost of manufacture are low.
The utility model, with respect to prior art, has following advantage and effect:
1, the utility model has adopted the locking disk, columniform tight lock part, and tight lock part offers annular groove, also is provided with reinforcing ring, has that simple in structure, convenient operation, structure are light, characteristics such as environmental protection, cost of manufacture are low.
2, be provided with reinforcing rib in the utility model; Have the advantages that firm degree is further strengthened.
3, the structure that is formed in one of the locking disk in the utility model, be convenient to processing, with low cost, sturdy and durable.
4, the utility model is exempted from weldering, and environmental protection and structure are light.

The specific embodiment
For ease of it will be appreciated by those skilled in the art that the utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment:
As shown in Fig. 1～4, a kind of vertical rod exempts to weld swollen type locking mechanism, comprise locking disk 1, locking disk 1 is inserted in vertical rod 2, vertical rod 2 is locked by expansion vertical rod 2 inside pipe walls after being inserted in locking disk 1, and two-way connecting pin 3 inserts vertical rod 2 one ends, two-way connecting pin 3 is connected by bolt 4 with vertical rod 2, and bolt 4 ends are provided with nut 5.
As shown in Figure 3, the button hole 10 in the present embodiment is 8,4 similar " ladder " shapes, 4 similar " circular arc " types, the devices such as available steel wire that act as of button hole 10 are fixed, the spoke 8 in the present embodiment is 8, spoke 8 act as stiffener intensity.
The present embodiment is in order to strengthen intensity, and spoke 8 bottoms are provided with reinforcing rib 11.Reinforcing rib 11 can be selected according to actual conditions, on tight lock part 6 sidewalls, offers through hole, and tight lock part 6 is by through hole and vertical rod 2 riveted joints, and the present embodiment riveting method is screw 12 riveted joints.
