Abstract

The utility model relates to an automatic opening structure of a multi-folding umbrella, which is composed of a middle rod (2) composed of an upper tube (21), a middle tube (22) and a lower tube (23), a movable nest (3), an umbrella frame (4), an upper nest (5), and a sheathing nest (6). The utility model is characterized in that an improved middle structure on each middle rod and a built-in spring are matched with the construction of the upper nest (5), which reduces the rust of the spring at an upper part and reduces the volume of the upper nest. When the umbrella is folded, the umbrella occupies smaller volume. Thus, the utility model is convenient to carry and store.

Description

A kind of many folding umbrella automatic deployment structures

The utility model relates to daily class, particularly a kind of many folding umbrella automatic deployment structures.

At present, automatic deployment structure commonly used, as shown in Figure 1, mainly be to offer a groove, and be equipped with the spring (11) that is placed in outside the middle rod, unify in conjunction with nest (12) in spring (11) upper group at last nest (1), by this, spring (11) provides the elastic force of automatic deployment.Because spring (11) is for exposing state, easily contact with moisture content and air, cause getting rusty and impaired; In addition, because the setting of last nest has bigger volume, therefore when closing one's umbrella, whole volume can't dwindle, and therefore is not easy to carry collection.

The purpose of this utility model provides a kind of antirust, little, portable many folding umbrella automatic deployment structures of volume.

The technical solution of the utility model:

According to the purpose of this utility model, a kind of many folding umbrella automatic deployment structures are provided, it mainly designs with bar structure and built-in spring in each joint of improvement, nest structure in the cooperation, upper springs is reduced get rusty, and it is long-pending to dwindle upper nest body, makes when closing one's umbrella, parachute kit also presents smaller volume relatively, is easy to carry or collects.

Accompanying drawings structure of the present utility model and embodiment:

Fig. 1 is the parachute-opening schematic diagram of common parachute kit.

Fig. 2 is a parachute-opening schematic diagram of the present utility model.

Fig. 3 is a cross-sectional schematic of the present utility model.

Fig. 4 is the cross-sectional schematic that closes one's umbrella of the present utility model.

(1) be last nest, (11) for spring, (12) in conjunction with nest, (2) for middle rod, (21) for last nest, (22) for middle pipe, (23) for pipe, (211) are spring for last nest, (6) for fit nest, (61) for umbrella frame frame, (5) for movable nest, (4) for cock body, (3) for spring, (221), (231) for baffle plate, (222), (232) for iner ledge, (212) down.

Shown in accompanying drawing 2 and accompanying drawing 3, the structure for a kind of triple folding umbrella mainly includes pipe (21), the middle rod (2) that is combined into of middle pipe (22) and lower pipe (23), movable nest (3) is placed in middle rod (2) The outside, upper nest (5) is made as open column shape, is installed in the outside, upper end of pipe (21), umbrella frame The inside of frame (4) is articulated in respectively the nest section of nest (5) and movable nest (3); In upper pipe (21) Fragment position is provided with an iner ledge (211), and is installed with a baffle plate (212) Yu Shangguan (21) inside, Top in iner ledge (211), the top of upper pipe (21) are provided with a fit nest (6) in addition, and can hold Put a spring (61), make spring (61) be dissolved in upper pipe (21) and fit nest (6) in built-in mode Inside, exposed structure is not by this avoided its spring get rusty damage and because spring (61) Be located in the pipe (21), do not increase the collection volume, make in carrying; At upper pipe (21) and middle pipe (22) and be equipped with cock body (221) and (231) between the lower pipe (23), establish with bullet in cock body top Spring (222), (232) Yu Shangguan (21) bottom and middle pipe (22) inside have spy simple in structure The point.

4 embodiment of the present utility model is described in conjunction with the accompanying drawings:

As shown in Figure 4, each spring all is compressed, and after system in movable nest (3) releasing, under the back stretch effect of each spring, each pipe is stretched, and movable nest moves on (3), and umbrella frame frame (4) is outer to be opened, and finishes the effect of automatic deployment.

The utility model is simple in structure, and is easy to use, volume is little, is easy to carry and collects, and is provided with built-in spring, avoids getting rusty, and prolonged the service life of umbrella.

Claims

1, a kind of many folding umbrella automatic deployment structures, it is by middle rod (2), movable nest (3), umbrella frame frame (4), last nest (5), fit nest (6) constitutes, it is characterized in that middle rod (2) is by last pipe (21), middle pipe (22) reaches down, and pipe (23) combines, wherein be provided with an iner ledge (211) in the stage casing of last pipe (21), and be installed with a baffle plate (212), top in iner ledge (211), the top of last pipe (21) is provided with a fit nest (6) in addition, can a ccontaining spring (61), make spring (61) be placed in the inside of pipe (21) and fit nest (6) in built-in mode; At last pipe (21) and middle pipe (22) and all establish cock body (221) and (231) down between the pipe (23), establish with spring (222), (232) on the top of cock body (221) and (231).
