Description

Technical Field

[0001] This utility model relates to the field of umbrella technology, and in particular to the rib structure of a straight-rib windproof umbrella. Background Technology

[0002] Umbrellas are an indispensable item in people's daily lives. When using umbrellas, most people encounter a common problem: on windy and rainy days, the strong wind often causes the umbrella surface to vibrate, and in severe cases, it may even flip up, causing the user to feel unsafe. This is especially true for straight-rib umbrellas, which are prone to breaking due to strong winds or damage to the hinges, affecting their lifespan. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a rib structure for a straight-rib windproof umbrella.

[0004] To achieve the above objectives, the technical solution of this utility model is to provide a rib structure for a straight-rib windproof umbrella, comprising: an upper umbrella nest disposed at the upper end of the umbrella pole, a lower umbrella nest slidably disposed on the umbrella pole, and a first rib hinged to the upper umbrella nest, wherein an energy-absorbing device is disposed between the first rib and the lower umbrella nest for supporting the first rib and for absorbing energy when the first rib is compressed.

[0005] A further improvement is that the energy-absorbing device includes: a first support bone hinged to the lower umbrella nest, a second support bone hinged to the first branch bone, and a connecting device disposed on the first support bone and the second support bone.

[0006] A further improvement is that the connecting device includes: a spring, nuts rotatably disposed at both ends of the spring, and connecting threads formed on the first support bone and the second support bone for matching the nuts.

[0007] A further improvement is that the spring is a tower-shaped spring, with the middle part of the tower-shaped spring bulging outward.

[0008] A further improvement is that a limiting groove is provided on the outer side of the nut, and the end of the spring is disposed within the limiting groove.

[0009] A further improvement is that the nut is hexagonal to enhance ease of rotation.

[0010] A further improvement is that a guide device is provided between the first support bone and the second support bone.

[0011] A further improvement is that the guiding device includes: a guide hole opened on the second support bone, and a guide post disposed on the first support bone for insertion into the guide hole.

[0012] A further improvement is that an anti-torsion block is provided on the second support bone, and a slot is formed on the anti-torsion block, with the first support bone hinged to the slot.

[0013] A further improvement is that a buffer layer is provided at the joint between the slot and the first bone.

[0014] The advantages and beneficial effects of this utility model are as follows:

[0015] With a simple structure and convenient use, it is equipped with a support for the first rib and an energy-absorbing device that can deform and absorb energy under pressure. This greatly reduces the pressure on the first rib when the umbrella surface is hit by strong winds, greatly improves the service life of the first rib, and improves the overall service life of the umbrella.

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0021] like Figures 1-3 As shown, the rib structure of a straight-rib windproof umbrella includes: an upper umbrella nest 102 disposed at the upper end of the umbrella pole 101, a lower umbrella nest 103 slidably disposed on the umbrella pole 101, and a first rib 104 hinged to the upper umbrella nest 102. An energy-absorbing device is disposed between the first rib 104 and the lower umbrella nest 103 for supporting the first rib 104 and absorbing energy when the first rib 104 is compressed.

[0022] In order to allow the first support bone 104 to displace and relieve force when under stress, and to prevent direct damage, the energy absorption device includes: a first support bone 105 hinged to the lower umbrella nest 103, a second support bone 106 hinged to the first support bone 104, and a connecting device disposed on the first support bone 105 and the second support bone 106. The connecting device includes: a spring 107, nuts 108 rotatably disposed at both ends of the spring 107, and connecting threads (not shown in the figure) formed on the first support bone 105 and the second support bone 106 for matching the nuts 108.

[0023] In order to enable the energy absorption device to withstand greater loads and impacts, and to have sufficient torsional resistance and lateral stability, the spring 107 is a tower-shaped spring 107, with the middle part of the tower-shaped spring 107 protruding outward.

[0024] To facilitate the rotation of the nut 108 and the connection with the first support bone 105 and the second support bone 106, a limiting groove 109 is provided on the outer side of the nut 108, and the end of the spring 107 is disposed in the limiting groove 109.

[0025] To improve ease of installation, the nut 108 is hexagonal to enhance the ease of rotation.

[0026] To further enhance the umbrella's torsional resistance, a guide device is provided between the first support rib 105 and the second support rib 106. The guide device includes: a guide hole (not shown in the figure) opened on the second support rib 106 and a guide post 110 provided on the first support rib 105 for insertion into the guide hole.

[0027] To enhance the connection strength between the second support bone 106 and the first branch bone 104 and improve the torsional resistance, an anti-torsion block 111 is provided on the second support bone 106. A slot 112 is provided on the anti-torsion block 111. The first branch bone 104 is hinged to the slot 112. A buffer layer 113 is also provided at the hinge point between the slot 112 and the first branch bone 104. The buffer layer 113 is a rubber layer.

[0028] Working principle: When in use, strong winds blow, creating pressure on the umbrella surface. This pressure acts on the first rib 104, which is then transmitted to the spring 107. This causes the spring 107 to compress accordingly, thus initially relieving the force on the first rib 104 and causing it to shift and displace, preventing it from breaking directly under strong pressure or folding upwards and damaging the hinge. This improves the lifespan of the umbrella ribs and the umbrella itself.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions above are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
