Abstract
The utility model discloses a kind of enhanced umbrella stems in end, with outside umbrella stem connecting pin and inside umbrella stem connecting pin, one side is the guide surface with inside umbrella stem connection, and the inside umbrella stem connecting pin of the guide surface has inner concave, it is characterised in that reinforcing rib is equipped on the inner concave.A kind of enhanced umbrella stem in end of the utility model is equipped with reinforcing rib on guiding inner concave, enhances the end of umbrella stem, is not in that stress is concentrated, the problem of avoiding umbrella stem deformation and performance is caused to decline even flexible failure.
Description
Technical field
The utility model relates to the part of en-toutcas more particularly to the scalable umbrella stems of extension umbrella, specifically a kind of
The enhanced umbrella stem in end.
Background technique
Existing scalable umbrella stem, such as scalable umbrella stem of three sections, including interior bar, middle bar and the outer bar being successively set with.It is adjacent
It is scalable between umbrella stem, and positioned by sheetmetal hoodle, it is flat that the connecting pin of adjacent umbrella stem is additionally provided with the limit for preventing umbrella stem from pulling
Face.
Referring to Figures 1 and 2, by taking the middle bar 2 of a routine as an example.The middle bar 2 has outer bar connecting pin 241 and interior bar
Connecting pin 242, a side are the guide surface 202 with interior bar connection, and the interior bar connecting pin 242 of the guide surface 202 has
The intersection on inner concave 210, the inner concave 210 and the top of guide surface 202 forms limit plane 209, the limit plane 209
Cooperate with the limit plane of interior bar upper end, can prevent interior bar from pulling.
The axially directed effect between adjacent umbrella stem can have both been played using inner concave, while can prevent umbrella stem from reversing,
Advantage is apparent.However, being concentrated in interior concave surface stress easy to form, umbrella since the body of rod of umbrella stem is thin-wall metal tube body
Bar will appear the phenomenon that deformation, not only affect the aesthetics of product, will cause umbrella stem flexible difficulty when serious, so as to shorten
The service life of product.
Summary of the invention
To be solved in the utility model is above-mentioned technical problem of the existing technology, it is desirable to provide a kind of end is enhanced
Umbrella stem.
To solve the above problems, the utility model uses following technical scheme: the enhanced umbrella stem in end, there is outside umbrella stem
Connecting pin and inside umbrella stem connecting pin, a side are the guide surface with inside umbrella stem connection, the inside umbrella of the guide surface
Bar connecting pin has inner concave, it is characterised in that reinforcing rib is equipped on the inner concave.
A kind of enhanced umbrella stem in end of the utility model is equipped with reinforcing rib on guiding inner concave, makes the end of umbrella stem
Enhanced, be not in that stress is concentrated, the problem of avoiding umbrella stem deformation and lead to performance decline or even flexible failure.
According to the utility model, the reinforcing rib can be attached on inner concave.A kind of embodiment of optimization, it is described
Reinforcing rib be to be outwardly protruded to be formed by the tube wall of umbrella stem.This reinforcing rib can be realized by impact style.
According to the utility model, the axial length of the reinforcing rib is 3.5~5.5mm.
Preferably, the axial length of the reinforcing rib is 4~6mm.
It is highly preferred that the axial length of the reinforcing rib is 5mm.
The umbrella stem is any inside umbrella stem of one group of adjacent expansion bar.
The umbrella stem is that the outer bar of three-section telescopic bar and/or middle bar, the interior bar lower end in three-section telescopic bar are directly connected to
Umbrella handle, therefore need not setting reinforcing rib.
The umbrella stem is outer bar, outer bar and middle bar any umbrella stem therein in four poles.Same reason,
Interior bar lower end in four section telescopic bars is directly connected to umbrella handle, therefore also need not setting reinforcing rib.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of existing middle bar.
Fig. 2 is the sectional view along A-A of Fig. 1.
Fig. 3 is the structural schematic diagram of bar in the utility model.
Fig. 4 is enlarged cross sectional views of the Fig. 3 along B-B.
Fig. 5 is enlarged cross sectional views of the Fig. 3 along C-C.
Fig. 6 is the structural schematic diagram that the utility model umbrella stem is applied to scalable umbrella stem.
In figure, 1- outer bar, bar in 2-, 3 interior bars；
The guide surface of bar and interior bar in 202-, the lower end 209- limit plane, 210- inner concave, 241- outer bar connecting pin,
242- interior bar connecting pin, 243- reinforcing rib.
Specific embodiment
Fig. 1 and Fig. 2 is the structural schematic diagram of existing middle bar, and defect is already discussed above, and details are not described herein.
Referring to Fig.1~Fig. 6, the enhanced umbrella stem in the end of the utility model.In the present embodiment, umbrella stem is flexible for three sections
The middle bar 2 of bar.But the utility model is not limited to middle bar, and the umbrella stem that any one needs is connect with inside umbrella stem in telescopic rod is equal
The technical solution of the utility model can be used, and belong in the protection scope of the utility model.
The middle bar 2 has outside umbrella stem (i.e. outer bar 1) connecting pin 241 and inside umbrella stem (i.e. interior bar 3) connecting pin
242, a side is the guide surface 202 with inside umbrella stem connection, and the inside umbrella stem connecting pin of the guide surface 202 has interior
Concave surface 210, the intersection of inner concave 210 and top guide surface 202 form limit plane 209, prevent interior bar 3 from therefrom drawing in bar 2
It is de-.
Reinforcing rib 243 is equipped on the inner concave 210.The reinforcing rib 243 can be arranged in any manner
On the inner concave 210, such as it is attached on inner concave 210.In the present embodiment, the reinforcing rib 243 is by umbrella
The tube wall of bar, which outwardly protrudes, to be formed.The reinforcing rib 243 of this form can be realized by impact style.
The axial length of the reinforcing rib is advisable with 3.5~5.5mm.
Preferably, the axial length of the reinforcing rib is 4~6mm.
It is highly preferred that the axial length of the reinforcing rib is 5mm.
A kind of enhanced umbrella stem in end of the utility model is equipped with reinforcing rib on guiding inner concave, makes the end of umbrella stem
Enhanced, be not in that stress is concentrated, the problem of avoiding umbrella stem deformation and lead to performance decline or even flexible failure.
The structure of the utility model is suitable for any inside umbrella stem of one group of adjacent expansion bar.
The structure of the utility model is equally applicable to the outer bar 1 in three pair rod, and 3 lower end of interior bar in three-section telescopic bar is direct
Umbrella handle is connected, therefore need not setting reinforcing rib.
The structure of the utility model is also applied for outer bar, outer bar and middle bar any umbrella therein in four poles
Bar.Same reason, the interior bar lower end in four section telescopic bars are directly connected to umbrella handle, therefore also need not setting reinforcing rib.
It is understood that above-described embodiment is the explanation to the utility model, rather than to the utility model
Limitation, any innovation and creation without departing from the utility model in essence scope each fall within the protection scope of the utility model
Within.
