Embodiment
To make the purpose of this utility model, technical scheme and effect clearer, clear and definite, give an actual example below new to this practicality
Type is further described.It should be appreciated that specific embodiment described herein is only used for explaining the utility model, it is not used to
Limit the utility model.
The present embodiment provides a kind of scaffold frame, is stacked with and formed about 1 by multiple frame units, as shown in figure 1, described
Frame unit 1 includes many vertical tubes 11 and transverse tube 12 being connected with each other, and T connector 13 is passed through between the transverse tube 12 and vertical tube 11
Connection, as shown in Fig. 2 T connector includes the tube expanding joint portion 131 of tubular and perpendicular pressure pipe connecting portion 132, it is described swollen
The inwall of pipe jointing part 131 is provided with groove 133, and the outer wall of pressure pipe connecting portion 132 is provided with groove 133, and the vertical tube 11 is matched somebody with somebody
The inner chamber of insertion tube expanding joint portion 131 is closed, and utilizes cold expanding technique clamping, the engagement sleeves of transverse tube 12 are outside pressure pipe connecting portion 132
Week, and utilize cold-press process clamping.
As shown in figure 3, when connecting transverse tube 12 and vertical tube 11 using T connector described in the present embodiment 13, first vertical tube 11 is matched somebody with somebody
Close and insert in the inner chamber in its tube expanding joint portion 131, by inflating cold expanding technique by positioned at the vertical tube 11 of the inner chamber of tube expanding joint portion 131
Outwards swell, deform its inner surface contour along tube expanding joint portion 131, because the inwall in tube expanding joint portion 131 is provided with recessed
Groove 133, so that the mutual clamping in tube expanding joint portion 131 of vertical tube 11 and T connector is connected；Then by the end of transverse tube 12
