Abstract

The utility model discloses an improved structure of an umbrella skeleton, including an upper nest, a middle nest, a lower nest, a stent, an umbrella opening spring, a multi-segment tube medium rod shrinking and sleeved. The upper nest is fixedly connected with the top end of the umbrella skeleton, and the upper nest and the middle nest are provided with a hollow sheath. The hollow inner cavity of the sheath is provided with the umbrella opening spring. Because the umbrella opening spring is arranged at the hollow inner cavity of the sheath, the diameter of the spring can be reduced and the force of closing the umbrella is also reduced. The umbrella opening spring is sealing at the inner cavity of the sheath without being easy to get erosion and rusting by the rainwater.

Description

The improvement structure of umbrella frame frame

The utility model relates to a kind of automatic umbrella, particularly relates to a kind of improvement structure of automatic umbrella rib frame.

The umbrella frame frame (as shown in Figure 1) of known automatic umbrella is middle excellent 5 ' and the deployment spring 7 ' formation by last nest 1 ', middle nest 2 ', following nest 3 ', support 4 ', the flexible fit of more piece pipe.The top of rod 5 ' during last nest 1 ' is fixed in by rivet 6 ', rod 5 ' periphery during middle nest 2 ', following nest 3 ' slip cap are connected on, on the rod 5 ', the upper and lower end of deployment spring 7 ' leaned respectively on middle nest 2 ', the following nest 3 ' during a deployment spring 7 ' was socketed in.When folding parachute kit, pulling downwards is nest 3 ' down, and the grab hole that nest 2 ' moved down together on following nest 3 ' during following nest 3 ' drove by support 4 ' is sticked on the grab, finishes folding of parachute kit.

The deployment spring 7 ' of this automatic umbrella is owing to need be placed on the periphery of middle rod 5 ', so it is thicker that the diameter of spring need be done, spring force is bigger, need parachute kit could be folded with bigger strength, volume after folding is also comparatively thick, and, be subjected to rain erosion easily and get rusty because deployment spring 7 ' is rod 5 ' periphery in being placed on.

The purpose of this utility model just provides the improvement structure of the less automatic umbrella rib frame of a kind of required strength that closes one's umbrella volume less, that fold the back parachute kit.

In order to achieve the above object, the improvement structure of the utility model umbrella frame frame, it comprises nest, middle nest, nest, support, deployment spring and by the middle rod of the flexible fit of more piece pipe down, last nest is fixed in the top of umbrella frame frame, middle nest, following nest are socketed on the middle rod, last nest, middle nest, nest arrangement in regular turn from top to bottom down are provided with the deployment spring that struts umbrella cover between last nest, following nest; Be provided with a hollow sleeve between last nest and middle nest, the affixed nest of going up in the upper end of this sleeve pipe during insert the bottom of this sleeve pipe in the rod, places deployment spring at the hollow cavity of this sleeve pipe; The upper end of rod during middle nest is fixed in, following nest slip cap is connected on the middle rod.

Because deployment spring of the present utility model is placed through the hollow cavity of sleeve pipe, the diameter of spring can dwindle greatly, has reduced the required strength that folds parachute kit, and because deployment spring is closed in cannula cavity, is difficult for being got rusty by rain erosion.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 1 is known umbrella rib structure;

Fig. 2 is the exploded view of the improvement structure of the utility model umbrella frame frame;

Fig. 3 is the cutaway view of the improvement structure of the utility model umbrella frame frame.

As Fig. 2, shown in Figure 3, the improvement structure of the utility model umbrella frame frame comprises middle excellent 6 of nest 1, middle nest 2, following nest 3, support 4, deployment spring 5 and the flexible fit of more piece pipe.Be provided with a hollow sleeve 7 between last nest 1 and middle nest 2, the affixed nest 1 of going up in the upper end of this sleeve pipe 7 during insert the bottom of this sleeve pipe 7 in the rod 6, places deployment spring 5 at the hollow cavity of this sleeve pipe 7; The upper end of rod 6 during middle nest 2 is fixed in by a pin that radially places 8 (also available rivet or screw); Following nest 3 slip caps are connected on the middle rod 6.The upper end that is placed through the deployment spring 5 in the hollow sleeve 7 leans the inner top surface at last nest 1, and excellent 6 inner chambers and leaning on described pin 8 during its lower end is stretched into screw togather the nut 10 of modification together on the top of last nest 1.Rod 6 is to be socketed to form by three joint

hollow tubes

61,62,63 in of the present utility model, and the utility model also is applicable to the automatic umbrella that is formed middle rod by more piece hollow tube sockets such as two joints or four joints.

When folding parachute kit, pulling downwards down nest 3 along in rod 6 move down, following nest 3 drives the hollow sleeve 7 of going up nest 1 and being fixed on the nest 1 by support 4 and moves down together, make sleeve pipe 7 further insert in excellent 6 inner chambers, the grab hole 31 of last nest 1 roof pressure deployment spring 5 on following nest 3 is sticked on the grab 9, finishes folding of parachute kit.

Claims

1, a kind of improvement structure of umbrella frame frame, it comprises nest, middle nest, nest, support, deployment spring and by the middle rod of the flexible fit of more piece pipe down, last nest is fixed in the top of umbrella frame frame, middle nest, following nest are socketed on the middle rod, last nest, middle nest, nest arrangement in regular turn from top to bottom down are provided with the deployment spring that struts umbrella cover between last nest, following nest; It is characterized in that: be provided with a hollow sleeve between last nest and middle nest, the affixed nest of going up in the upper end of this sleeve pipe during insert the bottom of this sleeve pipe in the rod, places deployment spring at the hollow cavity of this sleeve pipe; The upper end of rod during middle nest is fixed in, following nest slip cap is connected on the middle rod.

2, the improvement structure of umbrella frame frame according to claim 1 is characterized in that: the upper end of rod during nest is fixed in by a pin that radially places or rivet in described; The upper end that is placed through the deployment spring in the hollow sleeve leans the inner top surface at last nest, excellent inner chamber and leaning on described pin or rivet during its lower end is stretched into.
