Description

TECHNICAL FIELD

[0001] The utility model relates to a umbrella middle stick structure, especially a three-retracting umbrella middle stick structure of elastic force enhancement type. BACKGROUND

[0002] Three-retracting umbrella is a kind of three-section middle stick with mutual sleeve connection, the three-section middle stick is respectively the uppermost upper middle stick, the middle middle stick in middle part and the lower middle stick in lower part, upper honeycomb is equipped at the top of the upper middle stick, inner plug is equipped at the top of the middle middle stick, wherein, the umbrella supporting spring for supporting middle stick is only equipped in the middle middle stick and lower middle stick, and umbrella supporting spring is not equipped in the upper middle stick, but relies on the support rod of upper honeycomb and inner plug, the support rod is moved upwards with inner plug, and the upper middle stick is supported, to reach the purpose of supporting umbrella. When folding umbrella, the upper middle stick and the middle middle stick are folded by the power of the umbrella supporting spring on the umbrella rib, form three-retracting state (i.e. the lower middle stick in three-section middle stick is not folded), then, one hand holds the umbrella handle, and the other hand squeezes the umbrella top and folds the lower middle stick, realize folding umbrella.

[0003] The existing three-retracting umbrella is equipped with umbrella supporting spring only in the middle middle stick and lower middle stick, and the elastic force is not enough when opening umbrella, and the umbrella cannot be opened. People have thought of many solutions to solve this problem, such as increasing the elastic force of umbrella supporting spring, mostly using thicker and larger diameter umbrella supporting spring, but using such umbrella supporting spring causes the diameter of umbrella middle stick to increase, and the volume of whole umbrella increases, which is not only not beautiful, but also inconvenient to carry. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing a three-retracting umbrella middle stick structure of elastic force enhancement type, which can not increase the volume of whole umbrella after folding, but can enhance the elastic force of umbrella.

[0005] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A three-retracting umbrella middle stick structure of elastic force enhancement type, which comprises upper middle stick, middle middle stick and lower middle stick with mutual sleeve connection, upper honeycomb is equipped at the top of the upper middle stick, inner plug is equipped at the top of the middle middle stick, first spring is equipped in the middle middle stick and lower middle stick, the lower end of the first spring abuts against in the umbrella handle, support rod is equipped between the upper honeycomb and the inner plug, the lower middle stick comprises first lower middle stick and second lower middle stick with mutual sleeve connection, sleeve pipe is equipped in the middle middle stick, the upper end of the sleeve pipe is equipped with inwardly folded inner edge, the lower end of the sleeve pipe is equipped with outwardly folded outer edge, the upper end of the first spring abuts against on the inner edge, second spring is equipped between the outer wall of the sleeve pipe and the inner wall of the middle middle stick, the upper end of the second spring abuts against on the inner plug, and the lower end of the second spring abuts against on the outer edge of the sleeve pipe.

[0007] The utility model discloses a lower middle stick is by the first lower middle stick and the second lower middle stick of mutual sleeve connection, is equipped with the sleeve in the middle middle stick, the upper end of sleeve is equipped with the inside edge of inward folding, the lower end of sleeve is equipped with the outside edge of outward folding, and the upper end of first spring is abutted on the inside edge, is equipped with second spring between the outer wall of sleeve and the inner wall of middle middle stick, and the upper end of second spring is abutted on the inside plug, and the lower end of second spring is abutted on the outside edge of sleeve, because the second elastic spring is added, and the elasticity of second spring and first spring is greater than the strength of traditional umbrella supporting spring, so, without changing the original umbrella middle stick's appearance size and the total length of original middle stick, can also enhance the umbrella supporting force very well, therefore, the utility model has the advantage that the volume of whole umbrella will not increase after folding, but can enhance the umbrella supporting force. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 It is a sectional view structure schematic diagram of an embodiment of the utility model.

[0009] Figure 2 It is Figure 1 A place enlarged structure schematic diagram of. DETAILED DESCRIPTION

[0010] The technical scheme in the embodiment will be apparently, clearly and completely described in the embodiment in combination with the drawings, and obviously, the described embodiment is only a part of the embodiment in the embodiment, not all the embodiment.

[0011] The application will be further described in detail in combination with Figure 1 And Figure 2 .

[0012] Figure 1 And Figure 2 Disclosed is a three-retracting umbrella middle stick structure with enhanced elasticity, comprising upper middle stick 1, middle middle stick 2 and lower middle stick 3 which are mutually sleeved, upper honeycomb 11 is arranged at the top end of the upper middle stick 1, inner plug 21 is arranged at the top end of the middle middle stick 2, first spring 4 is arranged in the middle middle stick 2 and the lower middle stick 3, the lower end of the first spring 4 abuts against the umbrella handle, supporting rod 12 is arranged between the upper honeycomb 11 and the inner plug 21, the lower middle stick 3 is composed of first lower middle stick 31 and second lower middle stick 32 which are mutually sleeved, sleeve 22 is arranged in the middle middle stick 2, the upper end of the sleeve 22 is provided with inward folding inner edge 221, the lower end of the sleeve 22 is provided with outward folding outer edge 222, the upper end of the first spring 4 abuts against the inner edge 221, second spring 5 is arranged between the outer wall of the sleeve 22 and the inner wall of the middle middle stick 2, the upper end of the second spring 5 abuts against the inner plug 21, and the lower end of the second spring 5 abuts against the outer edge 222 of the sleeve 22.
