Abstract

The utility model discloses an automatic umbrella opening structure of an upright frame umbrella, comprising an upper nest, a middle nest, a lower nest, a support, an umbrella opening spring, an umbrella frame and a central bar, wherein the umbrella opening spring which is applied to open an umbrella cover is arranged between the upper nest and the lower nest, a hollow sleeve pipe is disposed between the upper nest and the lower nest, the top end of the sleeve pipe is fixedly connected with the upper nest, the lower portion of the sleeve pipe is inserted into the central bar, and the umbrella opening spring penetrates the hollow inner chamber of the sleeve pipe and is arranged inside the hollow inner chamber of the sleeve pipe , the middle nest is fixedly connected to the top end of the central bar, the lower nest is sleeved on the central bar via sliding. As the umbrella opening spring of the utility model penetrates the hollow inner chamber of the sleeve pipe and is arranged in the hollow inner chamber of the sleeve pipe, the diameter of the spring can be greatly reduced, thereby reducing the strength which is needed to fold the umbrella, and as the umbrella opening spring is closed in the inner chamber of the sleeve pipe, the umbrella opening spring can not be easily spoiled to rust by rain.

Description

The automatic parachute opener of vertical frame umbrella

Technical field

The utility model relates to a kind of automatic umbrella, particularly relates to a kind of automatic parachute opener of vertical frame umbrella.

Background technology

The umbrella frame frame (as shown in Figure 1) of known vertical frame umbrella is by last nest 1 ', middle nest 2 ', nest 3 ', support 4 ', middle excellent 5 ', umbrella frame 6 ' and deployment spring 7 ' constitute down.Excellent 5 ' top during last nest 1 ' is fixed in, rod 5 ' periphery during middle nest 2 ', following nest 3 ' slip cap are connected on, the upper and lower end of deployment spring 7 ' leans middle nest 2 ' respectively, nest 3 ' is socketed on middle excellent 5 ' down.When folding parachute kit, pulling downwards is nest 3 ' down, and nest 2 ' moved down grab hole on nest 3 ' down in being sticked on the excellent grab together during following nest 3 ' drove by support 4 ' and umbrella frame 6 ', finished folding of parachute kit.

At present the deployment spring 7 ' of vertical frame umbrella all is the periphery of rod 5 ' in being placed on, and so the diameter of spring is thicker, elastic force is bigger, then needs the bigger strength of usefulness parachute kit could be folded, and is subjected to rain erosion easily and gets rusty.

The utility model content

The purpose of this utility model just provides the automatic parachute opener of the less vertical frame umbrella of a kind of required strength that closes one's umbrella.

In order to achieve the above object, the automatic parachute opener of the utility model vertical frame umbrella, a kind of automatic parachute opener of vertical frame umbrella, it comprises nest, middle nest, following nest, support, deployment spring, umbrella frame and middle rod, is provided with the deployment spring that struts umbrella cover between last nest, middle nest; Wherein at last nest to down being provided with a hollow sleeve between the 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, is provided with 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.

The rod top is provided with the interior plug of spacing deployment spring in described.

Be provided with a packing ring between nest and the following nest in described.

Described nest down is provided with switch, and corresponding this switch is respectively equipped with the locating hole of nest under the location at the upper and lower of 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.

The specific embodiment

As Fig. 2, shown in Figure 3, the automatic parachute opener of the utility model vertical frame umbrella comprises nest 1, middle nest 2, following nest 3, support 4, deployment spring 5, umbrella frame 6 and middle excellent 7.

Be provided with a hollow sleeve 8 between last nest 1 and middle nest 2, the affixed nest 1 of going up in the upper end of this sleeve pipe 8 during insert the bottom of this sleeve pipe 8 in the rod 7, places deployment spring 5 at the hollow cavity of this sleeve pipe 8; The inner edge of nest 2 is provided with two convex shoulders 22 in (cooperating shown in Fig. 4,5,6), to being provided with two otch 73 in middle excellent 7 upper end by convex shoulder 22, two otch, the 73 interior back flange of rod 7 can be fixed in middle nest 2 upper end of middle rod 7 during two convex shoulders 22 of middle nest 2 were inserted, and the lower end of middle nest 2 connects a rubber washer 21, so that alleviate the impulse force of nest 3 centering nests 2 down; During being connected on, following nest 3 slip caps on the rod 7, below following nest 3, are provided with switch 31, to being respectively equipped with locating hole 71,72 at middle excellent 7 upper and lower by switch 31.The upper end that is placed through the deployment spring 5 in the hollow sleeve 8 leans the inner top surface at last nest 1, rod 7 during its lower end is stretched into, and the interior interior plug 9 of rod 7 is spacing to it in being located at by one.

As shown in Figure 7, when folding parachute kit, push switch 31, make switch 31 break away from locating hole 71, and pulling downwards down nest 3 along in rod 7 move down, following nest 3 drives the hollow sleeve 8 of going up nest 1 and being fixed on the nest 1 and moves down together by support 4, umbrella frame 6, make sleeve pipe 8 further insert in excellent 7 inner chambers, last nest 1 is pushed deployment spring 5 when the switch 31 on the following nest 3 just is snapped in locating hole 72, finishes folding of parachute kit.

When parachute-opening, push switch 31 makes switch 31 break away from locating holes 72, and under the effect of the restoring force of deployment spring 5, nest 1 drives umbrella frame 6 simultaneously umbrella cover is opened in the ejection.
