Existing ball curtain dome framework all welds brace mode by arc support rod, overall structure is solid form, and welding process complexity, and solder joint is many, and dome framework radian is difficult to guarantee, and this kind of dome framework can only be fixed on somewhere and be inconvenient to dismantle.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of dome frame structure system for convenience detach.

For reaching above object, be achieved through the following technical solutions:

A kind of dome frame structure system, comprising: node terminal pad and connecting rod; Terminal pad is column puck, and periphery is processed with the connecting hole that stretches to terminal pad central axis; Connecting rod is the bars of two ends with spring reset pin, and spring reset pin is for extending radially out in connecting rod external surface; Connecting hole inwall is processed with the detent for clamping spring reset pin; Terminal pad detent place side surface be processed be communicated with detent get bar mouth; Connecting hole inwall lower end is processed with downward-sloping guiding surface;

Adopt the utility model of technique scheme, a complete dome framework, the sphere fulcrum system framework being formed by multiple node terminal pads and connecting rod, for meeting the requirement of spherical frame structure, on node terminal pad, the quantity of connecting hole is no less than 5, and connecting hole is evenly distributed on node terminal pad outer wall circumference, so just guarantee that at connecting rod, stretching into assembling in connecting hole forms a sphere take node terminal pad as fixed point afterwards; Location is realized by the detent of the spring reset pin on connecting rod and connection hole in connecting rod and terminal pad location, and what form due to connecting rod and node terminal pad is spherical frame, need like this central axis of connecting rod and the transverse center plane of node terminal pad pure at certain angle, therefore in connecting hole inwall lower end, process downward-sloping guiding surface, and the surface of guiding surface is herein curved surfaces, can stablize like this connecting rod double swerve does not occur, guarantee the stability of structure;

Terminal pad guiding surface place end face is provided with edge under ring-type, under ring-type, along Surface Machining, there is the activity-oriented inclined-plane being connected with guiding surface, mainly be applicable to the situation that connecting rod is grown, by multi-processing, have under ring-type along further supporting linkage, and the Surface Machining activity-oriented inclined-plane on edge under ring-type, and activity-oriented inclined-plane center line and guiding surface center line are positioned on same fore-and-aft plane, and guiding surface is the identical cambered surface of radian with guiding surface, so just guaranteed still to keep stability after long connecting rod connects.

Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of manual, and for above and other object of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

Fig. 3 is main TV structure schematic diagram of the present utility model.

In figure: 1, node terminal pad, 2, connecting rod, 3, connecting hole, 4, spring reset pin, 5, detent, 6, get bar mouth, 7, guiding surface, 8, edge under ring-type, 9, activity-oriented inclined-plane.

The specific embodiment

A kind of dome frame structure system as shown in Figure 1, Figure 2 and Figure 3, comprising: node terminal pad 1 and connecting rod 2; Terminal pad 1 is column puck, and periphery is processed with the connecting hole 3 that stretches to terminal pad 1 central axis; Connecting rod 1 is the bars of two ends with spring reset pin 4, and spring reset pin 4 is for extending radially out in connecting rod 1 external surface; Connecting hole 3 inwalls are processed with the detent 5 for clamping spring reset pin 4; Terminal pad 1 detent 5 place side surfaces be processed be communicated with detent 5 get bar mouth 6; Connecting hole 3 inwall lower ends are processed with downward-sloping guiding surface 7;

Adopt the utility model of technique scheme, a complete dome framework, the sphere fulcrum system framework being formed by multiple node terminal pads 1 and connecting rod 2, for meeting the requirement of spherical frame structure, on node terminal pad 1, the quantity of connecting hole 3 is no less than 5, and connecting hole 3 is evenly distributed on node terminal pad 1 outer wall circumference, so just guarantee that at connecting rod 2, stretching into assembling in connecting hole 3 forms a sphere take node terminal pad 1 as fixed point afterwards; Connecting rod 2 is realized location with terminal pad 1 location by the spring reset pin 4 on connecting rod 2 and the detent 5 at connecting hole 3 places, and what form due to connecting rod 2 and node terminal pad 1 is spherical frame, need like this central axis of connecting rod 2 and the transverse center plane of node terminal pad 1 pure at certain angle, therefore in connecting hole inwall lower end, process downward-sloping guiding surface 7, and 7 surfaces of guiding surface are herein curved surfaces, can stablize like this connecting rod 2 double swerve does not occur, guarantee the stability of structure;

Terminal pad 1 guiding surface 7 place end faces are provided with under ring-type along 8, under ring-type, along 8 Surface Machining, there is the activity-oriented inclined-plane 9 being connected with guiding surface 7, mainly be applicable to the situation that connecting rod 2 is grown, by multi-processing, have under ring-type along 8 further supporting linkages 2, and under ring-type along 8 Surface Machining activity-oriented inclined-plane 9, and activity-oriented inclined-plane 9 center lines and guiding surface 7 center lines are positioned on same fore-and-aft plane, and guiding surface 9 is the identical cambered surface of radian with guiding surface 7, so just guaranteed still to keep stability after long connecting rod 2 connects.
