Preferably, the short rib comprises two folding sections and a pivot piece for connecting the two folding sections, the pull wire is installed at the lower end of the pivot piece and connected with the short rib through the pivot piece, and when the umbrella rib structure is folded, the two folding sections are folded upwards and close to each other.

Preferably, a stop pipe used for limiting the sliding sleeve is arranged at one end, opposite to the fixing piece, of the long bone.

Preferably, the long and short bones are fiberglass pieces.

By adopting the technical scheme, the utility model has the beneficial effects that:

the utility model provides a structure with a fixing piece, a baffle and a spring on a long bone, aiming at enabling a sliding sleeve to slide on the long bone and move towards an upper nest direction when an umbrella is influenced by wind power to generate an upturning trend, further extruding the baffle on the fixing piece and further compressing a buffer spring.

FIG. 2 is a schematic overall structure diagram of a second embodiment of the present invention;

fig. 3 is a schematic structural view of a second umbrella according to the embodiment of the present invention when folded.

Detailed Description

The following detailed description will be provided for the embodiments of the present invention with reference to specific embodiments, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.

Example one

Referring to fig. 1 and 2, a long-life straight rib umbrella comprises a central rod 1, a plurality of rib structures connected to the central rod 1, and an umbrella cover (not shown) mounted on each rib structure, the umbrella rib structure comprises an upper nest 11 fixed at the upper end of a middle rod 1, a middle nest 12 and a lower nest 13 sleeved on the middle rod 1, a long bone 2 with one end pivoted on the upper nest 11, a short bone 3 with one end pivoted on the middle nest 12 and a pull wire 4 with one end pivoted on the lower nest 13, the free end of the pull wire 4 is pivoted on the short bone 3, the free end of the short bone 3 is arranged in the middle of the long bone 2 through a movable joint 5, the movable joint 5 comprises a sliding sleeve 51, a pivoting part 52 arranged at the lower end of the sliding sleeve 51 and used for pivoting the short bone 3, a fixing part 53 used for limiting the sliding sleeve 51, a baffle plate 54 arranged on one side of the fixing part 53 close to the sliding sleeve and a buffer spring 55; structurally, the fixing piece 53, the baffle piece 54 and the spring 55 are arranged on the long bone 2, so that when the umbrella tends to be turned upwards under the influence of wind, the sliding sleeve 51 slides on the long bone 2 and moves towards the upper nest 11, and consequently the flaps 54 on the anchors 53, and consequently the buffer springs 55, are compressed, which conventional umbrellas are normally only resistant in the face of this by the flexibility of the ribs themselves, the umbrella frame is easy to break and deform when being subjected to larger wind force, so that the service life of the umbrella is reduced, the structure of the technical scheme can unload the force through the structures of the buffer spring 55 and the baffle plate 54 when the long rib 2 tends to be turned upwards, so that a buffer mechanism is added, the umbrella ribs can be effectively protected, the windproof effect is improved, and the integral service life of the umbrella is further prolonged;

in this embodiment, a stop tube 6 for limiting the sliding sleeve is arranged at one end of the long bone 2 opposite to the fixing piece; the structure of the baffle pipe 6 is arranged, so that the positions of the multiple sliding sleeves 51 can be limited, and the sliding sleeves 51 are prevented from being unnecessarily displaced after the long ribs 2 are bent, so that the integrity of the umbrella cover is prevented from being influenced;

in this embodiment, the long ribs 2 and the short ribs 3 are made of glass fiber, and the glass fiber has the advantages of light weight, good elasticity and high strength, and can well reduce the risk of breakage of the umbrella ribs.

Example two

Referring to fig. 3, in contrast to the first embodiment, in the present embodiment, the short rib 3 includes two folding sections 31 and a pivot 32 for connecting the two folding sections 31, the pull wire 4 is installed at the lower end of the pivot 32 and connected to the short rib 3 through the pivot 32, and when the rib structure is closed, the two folding sections 31 are folded upwards and close to each other; when the umbrella rib structure is folded, the short rib 3 is folded, the folding point is arranged at the lower end of the two folding sections 31, and the two folding sections 31 are supported through the pivot joint part 32 and the pull wire 4 when the umbrella rib structure is unfolded, so that the length of the short rib 3 is shortened while the using effect is ensured, and the structural strength of the short rib 3 is improved; meanwhile, the structure of the short ribs 3 reduces the slippage of the middle nest 12 and the lower nest 13, can be completed without carrying out larger actions when the umbrella is opened and closed, and improves the use convenience.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
