DETAILED DESCRIPTION

[0021] The specific implementation of the present application will be further described below in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the present application, and cannot be used to limit the protection scope of the present application.

[0022] AsFigures 1-4 As shown in the figure, a new type of carbon fiber umbrella rib comprises: an upper umbrella nest 104 arranged on the upper end of an umbrella rod 101, a lower umbrella nest 105 slidably arranged on the umbrella rod 101, a first branch rib 106 hingedly arranged on the upper umbrella nest 104, and a second branch rib 107 having one end hingedly connected to the lower umbrella nest 105 and the other end hingedly connected to the first branch rib 106. The tail of the first branch rib 106 is hingedly arranged with a swing branch rib 108. The swing branch rib 108 and the first branch rib 106 are provided with a force relief device for fixing the swing branch rib 108 and folding the swing branch rib 108 to relieve pressure when the first branch rib 106 is under severe pressure.

[0023] In order to fix the swing branch rib 108 at the tail of the first branch rib 106 and release the fixing to relieve pressure when under pressure, the force relief device comprises: two positioning grooves 109 opened on the swing branch rib 108, a fixing seat 110 fixedly arranged on the first branch rib 106, two extension blocks 111 arranged on the fixing seat 110 corresponding to the positioning grooves 109, and positioning blocks 112 arranged on the extension blocks 111 for inserting into the positioning grooves 109. The extension blocks 111 are elastic tubes that can spontaneously recover after deformation, thereby again clamping the swing branch rib 108. The extension blocks 111 are further provided with reinforcing devices. The elastic tubes are PP tubes.

[0024] In order to enhance the connection stability and strength between the swing branch rib 108 and the first branch rib 106 and prevent affecting pressure relief, the reinforcing device comprises: a sliding sleeve 113 sleeved on the two extension blocks 111, and a guide limiting device arranged between the sliding sleeve 113 and the extension blocks 111. The guide limiting device comprises: a guide groove 114 opened on the outer side of the extension block 111, and a guide block (not shown in the figure) arranged in the sliding sleeve 113 for cooperating with the guide groove 114. The guide groove 114 extends to the hinge joint between the swing branch rib 108 and the first branch rib 106.

[0025] In order to facilitate the user to reset the folded swing branch rib 108 more quickly, a round corner 115 is opened on the positioning block 112 to facilitate the quick resetting of the swing branch rib 108.

[0026] In order to improve the fit of the extension block 111 and the swing branch rib 108, thereby enhancing the connection strength and preventing folding during daily use, the side of the extension block 111 close to the swing branch rib 108 is matched with the swing branch rib 108.

[0027] In order to facilitate the connection of the umbrella rib and the umbrella cloth and reduce the production process, the swing branch rib 108 is provided with an umbrella bead 117 for facilitating the connection with the umbrella cloth.

[0028] In order to enhance the stability of the articulation between the first branch bone 106 and the second branch bone 107, the second branch bone 107 tail is provided with a reinforcing block 119, the reinforcing block 119 is provided with a slot 120, and the first branch bone 106 is articulated in the slot 120 to improve the stability.

[0029] In order to prevent the first branch bone 106 and the second branch bone 107 from being worn at the articulation, the slot 120 is also provided with a buffer layer 121 at the articulation of the first branch bone 106, and the buffer layer 121 is a rubber layer.

[0030] The first branch bone 106, the swing branch bone 108 and the second branch bone 107 are all carbon fiber umbrella ribs.

[0031] Working principle: when in use, the user opens the umbrella, and when the umbrella is impacted by strong wind and heavy rain, the umbrella cloth will exert pressure on the swing branch bone 108 and the first branch bone 106; when the pressure is too large, the swing branch bone 108 will push open the elastic extension block 111, thereby releasing the clamping of the positioning groove 109 and the positioning block 112, and moving the sliding sleeve 113 to the fixed seat 110; at this time, the swing branch bone 108 and the first branch bone 106 can be released, so that the swing branch bone 108 can be folded to release pressure when under pressure, preventing the first branch bone 106 from being damaged by folding;

[0032] When recovering, the user directly bends the swing branch bone 108 with his hand to make it re-clamp the extension block 111, and then moves the sliding sleeve 113 to the side close to the swing branch bone 108 to complete the recovery, which is convenient for the user to use multiple times and prolongs the service life of the umbrella.

[0033] The basic principles and main features of the utility model and its advantages are shown and described above, and those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only to illustrate the principles of the utility model, and various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed, and the scope of protection of the utility model is defined by the appended claims and their equivalents.
