Abstract

A nest body structure of a self-opening umbrella comprises a middle nest (2), a lower nest (3) and an umbrella opening spring (5), wherein the middle nest (2) and the lower nest (3) are connected to an umbrella middle bar (1) in a sliding and sleeved mode, and the umbrella opening spring (5) is clamped between the middle nest (2) and the lower nest (3) and connected to the outside of the umbrella middle bar (1) in a sleeved mode. The lower nest (3) extends downwards to form a lengthening sleeve (31), the middle nest (2) extends downwards to form a guide pipe (21), the umbrella opening spring (5) is installed at the bottom of an inner cavity of the lengthening sleeve (31), the guide pipe (21) is inserted in the inner cavity of the lengthening sleeve (31) of the lower nest (3), and the top of the umbrella opening spring (5) abuts against the bottom of the guide pipe (21). According to the nest body structure of the self-opening umbrella, the umbrella opening spring can be completely hidden in the lower nest, the appearance is attractive, and the phenomenon of clamping hands can be avoided. In addition, a nest body can be made to be thinner, so that the nest body structure of the self-opening umbrella is convenient to carry and store.

Description

The nest body structure of automatic umbrella

Technical field

The utility model relates to a kind of parachute kit, relates in particular to a kind of architecture advances of nest body structure deployment spring place of automatic umbrella.

Background technology

The nest body structure of existing automatic umbrella, to be slidably socketed a sandwiched deployment spring between middle nest outside middle rod and lower nest mostly, but this deployment spring is directly exposed to outer, and when the nest of down leaving behind closed one's umbrella, this deployment spring was compressed, and during parachute-opening, deployment spring extends under the effect of self tension force, thereby the distance between middle nest and lower nest increases umbrella frame is opened, but because deployment spring is directly exposed to outside, neither attractive in appearance, the phenomenon of tong also may occur.In addition, existing deployment spring is all that to be enclosed within the guiding pipe of middle nest downward-extension outer, and the diameter of deployment spring is generally all done greatlyr thus, and correspondingly, the diameter of lower nest sleeve also will be done greatlyr, is unfavorable for like this reducing size of folded umbrella.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of and deployment spring can be stashed and the nest body structure of the automatic umbrella that the nest body can be done carefullyyer.

The technical scheme in the invention for solving the above technical problem is, manufacture and design a kind of nest body structure of automatic umbrella, comprising: be slidably socketed middle nest and lower nest in umbrella shaft, be folded between described middle nest and lower nest and be socketed on deployment spring outside described middle rod.

Described lower nest is extended with lengthening sleeve downwards, described middle nest is extended with guiding pipe downwards, described deployment spring is arranged on the intracavity bottom of described lengthening sleeve, and this guiding pipe inserts the lengthening sleeve inner chamber of described lower nest, and described deployment spring top and described guiding pipe bottom offset.

Compared with the existing technology, its deployment spring of nest body structure of automatic umbrella of the present utility model is arranged on the intracavity bottom of lower nest, can not expose outside, and the profile of umbrella frame is more attractive in appearance, also can not produce the phenomenon of spring tong, uses safer; The deployment spring top is directly with the extension tube bottom of middle nest, to offset simultaneously, rely on lower nest inwall to carry out the correcting deployment spring, the diameter of deployment spring can be done littlely thus, thereby the diameter of lower nest also can correspondingly be done littlely, can greatly reduce size of folded umbrella, be convenient for carrying.

Description of drawings

Fig. 1 is the umbrella rib structure schematic diagram with the nest body structure of the utility model automatic umbrella;

Fig. 2 is the exploded view of the nest body structure of the utility model automatic umbrella;

Fig. 3 is the cutaway view of the nest body structure of the utility model automatic umbrella.

The specific embodiment

Be described in further detail below in conjunction with the most preferred embodiment shown in accompanying drawing.

As depicted in figs. 1 and 2, the nest body structure of the utility model automatic umbrella comprises: be slidably socketed middle nest 2 and lower nest 3 in umbrella shaft 1, be folded between described middle nest 2 and lower nest 3 and be socketed on deployment spring 5 outside described middle excellent 1.

As shown in Figure 3.Described lower nest 3 is extended with lengthening sleeve 31 downwards, and described middle nest 2 is extended with guiding pipe 21 downwards.Special feature of the present utility model is: described deployment spring 5 is arranged on the intracavity bottom of described lengthening sleeve 31, thereby this guiding pipe 21 inserts below lengthening sleeve 31 inner chambers of described lower nest 3 are pressed in deployment spring 5 from top to bottom, these deployment spring 5 tops directly offset with the bottom of described guiding pipe 21, and these deployment spring 5 bottoms offset to projecting inward terrace with lengthening sleeve 31 intracavity bottoms.

After adopting said structure, no matter be at deployed condition or umbrella closing state, described deployment spring 5 all is pressed in the inner chamber of lower nest 3 lengthening sleeves 31 and can't exposes by guiding pipe 21, makes thus umbrella frame more attractive in appearance, and can not produce the phenomenon of spring tong.In addition, as Fig. 3, because deployment spring 5 tops are to offset with the annular bottom surface of guiding pipe 21, therefore the diameter of this deployment spring 5 should be almost big or small with the diameter of guiding pipe 21, diameter much smaller than existing deployment spring, and the internal diameter of described lower nest 3 lengthening sleeves 31 is only slightly large than the external diameter of deployment spring 5,, to its effect with correcting, prevents deployment spring 5 and umbrella shaft 1 friction in the process that deployment spring 5 stretches and compresses.Like this, the diameter of lower nest 3 lengthening sleeves 31 also can be done very littlely, is conducive to reduce the size of folded umbrella of umbrella, is convenient for carrying and collects.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model.To one skilled in the art, the utility model can have various modifications and variations, and is all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.

Claims

1. the nest body structure of an automatic umbrella comprises: be slidably socketed middle nest (2) and lower nest (3) in umbrella shaft (1), be folded between described middle nest (2) and lower nest (3) and be socketed on deployment spring (5) outside described middle rod (1); It is characterized in that:

Described lower nest (3) is extended with lengthening sleeve (31) downwards, described middle nest (2) is extended with guiding pipe (21) downwards, described deployment spring (5) is arranged on the intracavity bottom of described lengthening sleeve (31), this guiding pipe (21) inserts lengthening sleeve (31) inner chamber of described lower nest (3), and described deployment spring (5) top and described guiding pipe (21) bottom offset.
