Abstract

An automatic umbrella, comprising a medium rod (1), an upper nest (2) which is fixing sleeved on the top of the medium rod (1), a medium nest (3) and a lower nest (4) which are sliding sleeved on the medium rod (1), an umbrella opening spring (5) which is sleeved on the medium rod (1) is arranged between the medium nest (3) and the lower nest (4), also comprising a guide positive sleeve (6) which is used for jointing the umbrella opening spring (5). The lower segment of the guide positive sleeve (6) is inserted downward into a medium hole (41) of the lower nest (4) and sliding coordinate with the medium hole (41); the guide positive sleeve (6) completely shields the upper segment of the medium hole (41) arranging on the lower nest (4) of the umbrella opening spring (5). The utility model automatic umbrella can prevent the umbrella opening spring from deflection, make the umbrella open and close smoothly, and has beautiful appearance, the phenomenon of spring clipping hand will not happen, the utility model can be fit for all kinds of automatic umbrella.

Description

Automatic umbrella

Technical field

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

Background technology

Existing automatic umbrella, be mostly in slip cap is connected on the rod outside middle nest and following nest between insert and put a deployment spring, but this deployment spring is directly exposed to outer, when the nest of down leaving behind closes one's umbrella, this deployment spring is compressed, and during parachute-opening, deployment spring promotes umbrella frame and opens under the effect of self tension force, because the space between middle rod and the deployment spring is bigger, the deployment spring middle part is easy to take place the phenomenon of inclined to one side side, cause to open to close one's umbrella smooth and easyly inadequately, and deployment spring is directly exposed to outer neither attractive in appearancely, and the phenomenon of tong also may take place.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of deployment spring that prevents opening the automatic umbrella that inclined to one side side takes place when closing one's umbrella.

The technical scheme in the invention for solving the above technical problem is, manufacture and design a kind of automatic umbrella, comprise: middle rod, fixedly sleeved in described excellent top on nest, slip cap be connected on described in the middle nest and the following nest of rod, insert and put one between nest and the following nest in described and be socketed in described middle excellent deployment spring; In addition, also comprise the correcting sleeve of the described deployment spring of socket, the hypomere of described correcting sleeve stretches into the mesopore of described nest down downwards and is slidingly matched with this mesopore, and described correcting sleeve covers described deployment spring fully and exposes the described epimere of nest mesopore down.Deployment spring promptly is limited in the sleeve and can produce inclined to one side side like this.

Described sleeve can adopt following two kinds of frame modes:

First kind, described correcting sleeve top radially be extended with toward in a circle spacing in the edge, describedly contact with the top of described deployment spring along the bottom in spacing.The correcting sleeve is supported to the bottom of middle nest by deployment spring and also can stretch up and down with the mesopore of nest under the flexible and corresponding edge of variable in distance between middle nest and the following nest and deployment spring like this.

Second kind, described correcting sleeve top be fixed on described in the bottom of nest.The correcting sleeve equally can be flexible up and down with the mesopore of nest under the flexible and corresponding edge of variable in distance between middle nest and the following nest and deployment spring like this.

Compare with prior art, its deployment spring of automatic umbrella of the present utility model is limited in the correcting sleeve, can prevent effectively that deployment spring from opening the inclined to one side side phenomenon because of produced by force unbalance when closing one's umbrella, make automatic umbrella open when closing one's umbrella more smooth and easy, and deployment spring crested, the profile of umbrella frame is more attractive in appearance, also can not produce the phenomenon of spring tong, uses safer.

Description of drawings

Fig. 1 is the structural representation of the automatic umbrella of the utility model;

Fig. 2 is that described correcting sleeve 6, deployment spring 5 reach the sectional exploded view of nest 4 down;

Fig. 3 cuts open figure for deployment spring under the assembled state 5 with the office at correcting sleeve 6 and following nest 4 places.

The specific embodiment

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

As shown in Figure 1, rod 1 during automatic pack of the present utility model is drawn together, fixedly sleeved in described excellent 1 top on nest 2, slip cap be connected on described in the middle nest 3 and the following nest 4 of rod 1, as shown in Figures 2 and 3, insert and put one between described middle nest 3 and the following nest 4 and be socketed in described middle excellent 1 deployment spring 5.Its special feature is: the described deployment spring 5 outer correcting sleeves 6 that are socketed with, the intracavity diameter of this correcting sleeve 6 is bigger slightly than the external diameter of deployment spring 5, make and to slide relatively smoothly between deployment spring 5 and correcting sleeve 6 inwalls, also can prevent deployment spring 5 inclined to one side sides simultaneously; Simultaneously, the described diameter of the mesopore 41 of nest 4 is down done greatly and just in time can be held described deployment spring 5 and correcting sleeve 6 thereof, and the hypomere of described correcting sleeve 6 stretches into the mesopore 41 of described nest 4 down downwards and is slidingly matched with this mesopore 41.Distance in described between nest 3 and the following nest 4 is maximum, be that umbrella is when strutting fully, the hypomere of described correcting sleeve 6 still is positioned at the mesopore 41 of nest 4 down, this makes described correcting sleeve 6 at any time all can cover described deployment spring 5 fully may expose the described epimere of nest 4 mesopores 41 down, not only can prevent deployment spring 5 inclined to one side sides, also make the umbrella frame profile more attractive in appearance and can prevent the spring tong.

Described correcting sleeve 6 can adopt following two kinds of frame modes:

First kind, as shown in Figure 2, described correcting sleeve 6 tops radially be extended with toward in a circle spacing in along 61, describedly contact along the top of 61 bottoms in spacing with described deployment spring 5.

Second kind, described correcting sleeve 6 tops be fixed on described in the bottom of nest 3.(not shown)

No matter correcting sleeve 6 adopts any structure, all can be flexible up and down with the mesopore of nest under the flexible and corresponding edge of variable in distance between middle nest 3 and the following nest 4 and deployment spring 5, can reach the purpose that prevents the inclined to one side side of spring equally.

Claims

1. automatic umbrella, comprise: middle rod (1), fixedly sleeved in described last nest (2), the slip cap at rod (1) top be connected on described in middle nest (3) and the following nest (4) of rod (1), insert and put a deployment spring (5) that is socketed in described middle excellent (1) between described middle nest (3) and the following nest (4); It is characterized in that:

The correcting sleeve (6) that also comprises the described deployment spring of socket (5), the hypomere of described correcting sleeve (6) stretches into the mesopore (41) of described nest (4) down downwards and is slidingly matched with this mesopore (41), and described correcting sleeve (6) covers described deployment spring (5) fully and exposes the described epimere of nest (4) mesopore (41) down.

2. automatic umbrella according to claim 1 is characterized in that: described correcting sleeve (6) top radially is extended with a circle toward in spacing interior along (61), and bottom, described spacing interior edge (61) contacts with the top of described deployment spring (5).
