Abstract
A kind of elastic force enhancement mode umbrella shaft, comprises middle excellent main body, is provided with the spring for producing elastic force during parachute-opening in described middle excellent main body, and described spring is to small end with hold holding greatly the spring be connected in sequence greatly by the small end of plural pagoda spring; Or to be curled up by a spring line there is the spring that plural pagoda spring formula structure forms.The utility model has when in not increasing when excellent principal length, can improve the advantage of parachute-opening elastic force further.
Description
Technical field
The utility model relates to a kind of elastic force enhancement mode umbrella shaft.
Background technology
No matter existing automatic umbrella, be vertical frame umbrella or folded umbrella, all have umbrella shaft.Existing umbrella shaft, as shown in Figure 1, common umbrella shaft comprises middle excellent body 100, described middle excellent body 100 is placed for installing for several umbrella frame 200, spring 300, stay cord 400, slide block 500 is provided with in described middle excellent main body 100, the bottom of described spring 300 is supported on described slide block 500, and one end of described stay cord 400 is connected with described slide block 500, and the other end of described stay cord 300 is connected with described lower nest 800 after walking around the runner 700 being positioned at nest 600 bottom; When the present invention is deployed, unclamp lower nest 800, under the tension force effect of spring 300, stay cord 400 is by lower nest 800 toward pull-up, and outwards opened by umbrella frame 200, umbrella cover is opened; When closing one's umbrella, lower nest 800 is under the effect of external force, and excellent main body 100 slide downward in edge, now, spring 300 being compressed under upper pulling force effect at slide block 400, by umbrella frame 200 inward collapsible, umbrella cover is drawn in.
It is cylindrically coiled spring that spring 300 in existing umbrella shaft all adopts, and the diameter often enclosed due to cylindrically coiled spring is equal, like this, when closing one's umbrella, even if cylindrically coiled spring is compressed completely, it also will occupy suitable one section of space of middle excellent main body, and the parachute-opening elastic force of umbrella shaft is restricted.
Utility model content
In order to overcome above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of when in not increasing when excellent principal length, can improve the elastic force enhancement mode umbrella shaft of parachute-opening elastic force further.
The technical solution of the utility model is: provide a kind of elastic force enhancement mode umbrella shaft, comprise middle excellent main body, be provided with in described middle excellent main body and produce the spring of elastic force for during parachute-opening, described spring is to small end with hold holding greatly the spring be connected in sequence greatly by the small end of plural pagoda spring; Or to be curled up by a spring line there is the spring that plural pagoda spring formula structure forms.
As to improvement of the present utility model, described middle excellent main body is excellent main body in straight bar type.
As to improvement of the present utility model, described middle excellent main body is made up of more piece, can stretch between adjacent two joints.
The utility model is owing to have employed the structure of more piece pagoda spring series connection, when compressing completely, at pagoda spring, there is the length shorter than the cylindrically coiled spring of same number of turns, therefore, during the utility model can be implemented in and do not increase when excellent principal length, can further improve the object of parachute-opening elastic force.

Detailed description of the invention
Embodiment 1
Refer to Fig. 2, what Fig. 2 disclosed is a kind of elastic force enhancement mode umbrella shaft, comprise middle excellent body 1, described middle excellent body 1 is placed for installing for several umbrella frame 2, spring 3, stay cord 4, slide block 5 is provided with in described middle excellent main body 1, the bottom of described spring 3 is supported on described slide block 5, and one end of described stay cord 4 is connected with described slide block 5, and the other end of described stay cord 3 is connected with described lower nest 8 after walking around the runner 7 being positioned at nest 6 bottom; When the present invention is deployed, unclamp lower nest 8, under the tension force effect of spring 3, stay cord 4 is by lower nest 8 toward pull-up, and outwards opened by umbrella frame 2, umbrella cover is opened; When closing one's umbrella, lower nest 8 under the effect of external force, along in excellent main body 1 slide downward, now, spring 3 being compressed under upper pulling force effect at slide block 4, by umbrella frame 2 inward collapsible, umbrella cover is drawn in; In the present embodiment, described spring 3 be curled up by a spring line there is the spring that plural pagoda spring formula structure forms; Obviously, described spring 3 can also be designed to by small end 32 pairs of small ends of plural pagoda spring 31 and hold greatly 33 to holding greatly the spring (see Fig. 5) be connected in sequence.
Embodiment 2
Refer to Fig. 3 and Fig. 4, a kind of elastic force enhancement mode of Fig. 3 and Fig. 4 umbrella shaft, comprise middle excellent body 1, described middle excellent body 1 is placed for installing for several umbrella frame 2, spring 3, stay cord 4, slide block 5 is provided with in described middle excellent main body 1, the bottom of described spring 3 is supported on described slide block 5, and one end of described stay cord 4 is connected with described slide block 5, and the other end of described stay cord 3 is connected with described lower nest 8 after walking around the runner 7 being positioned at nest 6 bottom; When the present invention is deployed, unclamp lower nest 8, under the tension force effect of spring 3, stay cord 4 is by lower nest 8 toward pull-up, and outwards opened by umbrella frame 2, umbrella cover is opened; When closing one's umbrella, lower nest 8 under the effect of external force, along in excellent main body 1 slide downward, now, spring 3 being compressed under upper pulling force effect at slide block 4, by umbrella frame 2 inward collapsible, umbrella cover is drawn in; In the present embodiment, described middle excellent main body 1 is made up of more piece, can stretch between adjacent two joints, specifically, described middle excellent main body 1 be by lower middle excellent 11, in rod 12 and upper excellent 13 3 joints form, can stretch between rod during upper, neutralization is lower, described lower middle rod and in be provided with cylindrically coiled spring in rod; And be provided with in described upper excellent 13 curled up by a spring line there is the spring 3 that plural pagoda spring formula structure forms; Obviously, described spring 3 can also be designed to by small end 32 pairs of small ends of plural pagoda spring 31 and hold greatly 33 to holding greatly the spring (see Fig. 5) be connected in sequence; Obviously, according in the sleeve pipe (if any) that also spring 3 can be located in middle excellent main body 1.
