Detailed Implementation

[0019] 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.

[0020] like Figs. 1-3As shown, a high-toughness anti-breaking round steel umbrella rib made umbrella includes a middle rod 101, a handle 102 arranged at the bottom of the middle rod 101, an upper umbrella nest 103 arranged at the top of the middle rod 101, a lower umbrella nest 104 slidably arranged on the middle rod 101, a first branch rib 105 hingedly arranged on the upper umbrella nest 103, and a second branch rib 106 hingedly arranged on the lower umbrella nest 104. The first branch rib 105 is provided with an umbrella cloth 107, and the other end of the second branch rib 106 is hingedly connected with the first branch rib 105 through elastic devices.

[0021] In order to hinge the first branch rib 105 and the second branch rib 106 together, the elastic devices include a mounting seat 108 arranged on the second branch rib 106 through a buffering device, and a rotating block 109 rotatably arranged on the mounting seat 108 through rotating devices. The first branch rib 105 is fixedly connected with the rotating block 109.

[0022] In order to facilitate the rotation of the first branch rib 105 and the second branch rib 106, the rotating devices include two elastic plates 110 arranged on the mounting seat 108. The rotating block 109 is spherical, and a rotating clamping groove 111 matched with the rotating block 109 is formed between the two elastic plates 110. The rotating clamping groove 111 is strip-shaped, and an anti-disengagement device is further arranged between the two elastic plates 110.

[0023] In order to absorb and relieve the force at the hinge of the first branch rib 105 and the second branch rib 106, the rotating block 109 is a rubber ball, and a rubber layer 112 for enhancing the buffering effect is further arranged on the first branch rib 105 and fixedly connected with the rotating block 109.

[0024] In order to buffer the effect of the umbrella cloth 107 on the first branch rib 105 and the force acting on the second branch rib 106, the buffering device includes a mounting sleeve 113 arranged at the bottom of the mounting seat 108 and matched with the second branch rib 106, and an energy-absorbing block 114 fixedly connected with the bottom of the mounting seat 108 at one end and with the second branch rib 106 at the other end. The energy-absorbing block 114 is smaller than the hole diameter of the mounting sleeve 113, and the energy-absorbing block is a rubber block.

[0025] In order to enhance the use stability of the umbrella and prevent the first branch rib 105 from being separated from the second branch rib 106 due to excessive force, the anti-disengagement device includes a threaded through hole 119 formed on the elastic sheet, and a screw (not shown in the figure) locked in the threaded through hole 119 for preventing the elastic sheet from being directly separated due to excessive pressure. During use, the user can also adjust the distance between the two elastic plates through the screw, so as to adjust the clamping force.

[0026] In order to place the umbrella more conveniently, a curved hook 116 is further arranged on the handle 102.

[0027] In order to improve the safety of night travel, the umbrella cloth 107 is further provided with a reflective band 117 for improving the safety of night travel.

[0028] In order to prevent damage to the upper umbrella nest 103 and facilitate placement of the umbrella, the middle rod 101 is further provided with a umbrella tip 118 for protecting the upper umbrella nest 103.

[0029] In order to further prevent the umbrella rib from breaking, the first branch rib 105 is a first round steel branch rib, and the second branch rib 106 is a second round steel branch rib.

[0030] Working principle: in use, the umbrella is opened, when the strong wind blows, the umbrella cloth 107 bears a certain pressure, then the pressure is transmitted from the umbrella cloth 107 to the first branch rib 105, the first branch rib 105 is forced to drive the rotating block 109 to slide in the strip-shaped rotating clamping groove 111, thereby preliminarily relieving the pressure, then the pressure is conducted to the mounting seat 108, so that the energy-absorbing block 114 is deformed, thereby absorbing the pressure twice, so as to prevent damage to the hinge and the umbrella rib, and improve the service life of the umbrella.

[0031] The basic principle and main features of the utility model and its advantages are shown and described above, and the skilled in the art should understand that the utility model is not limited by the above examples, the above examples and the description in the description are only to illustrate the principle of the utility model, without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, these changes and improvements all fall within the scope of the utility model claimed, the scope of protection of the utility model is defined by the appended claims and their equivalents.
