DETAILED DESCRIPTION

[0016] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0017] like Figure 1-Figure 5 As shown, an umbrella handle assembly device includes a frame 101, on which a handle clamping device for fixing the umbrella handle is provided, and a sliding plate 102 is also provided on the frame 101 through an elastic sliding device, and a middle rod clamping device for fixing the middle rod is provided on the sliding plate 102, and a rotating device for driving the middle rod to rotate and preventing the middle rod from being damaged due to the threaded connection between the middle rod and the umbrella handle being too tight.

[0018] In order to facilitate the fixing of the middle rod, the middle rod clamping device includes: two bearing seats 103 arranged on the sliding plate 102, a roller 104 rotatably arranged on the bearing seat 103, at least three arc-shaped clamping blocks 105 slidably arranged in the roller 104 through an elastic device for clamping and positioning the middle rod, and a chamfer 106 opened on the arc-shaped clamping block 105.

[0019] In order to position the middle rod at the center of the roller 104, the elastic device includes: at least two guide pillars 107 arranged on the arc-shaped clamping block 105, a guide sleeve 108 arranged on the roller 104 and matching the guide pillars 107, a first spring 109 sleeved on the guide sleeve 108 with one end abutting against the arc-shaped clamping block 105 and the other end abutting against the roller 104, and a limiting pin 110 arranged on the guide pillar 107.

[0020] In order to facilitate the driving of the roller 104 to rotate, the rotating device includes: a servo motor 111 arranged on the sliding plate 102, a first sprocket 112 arranged on the roller 104 through a pressure device, a reduction gear box 113 arranged on the sliding plate 102 and connected to the rotating rod of the servo motor 111, a second sprocket 114 arranged on the output end of the reduction gear box 113, and a transmission chain 115 arranged between the first sprocket 112 and the second sprocket 114.

[0021] In order to facilitate the adjustment of the fastening force between the first sprocket 112 and the roller 104, thereby preventing the middle rod from being damaged due to excessive connection with the umbrella handle, the pressure device includes: an air cushion ring 116 sleeved on the roller, a stabilizing ring 117 arranged in the air cushion ring 116, the first sprocket 112 is sleeved on the air cushion ring 116, and a plurality of anti-slip blocks 118 are arranged between the air cushion ring 116 and the first sprocket 112, and an anti-slip groove 119 matching the anti-slip block 118 is opened on the first sprocket 112; When in use, the user pumps air into the air cushion ring 116 to make it close to the roller, generating a certain friction force, so that the roller can rotate with the first sprocket. When the resistance of tightening the umbrella handle and the middle rod is greater than the friction force, the first sprocket will start to idle, thereby preventing damage to the umbrella handle and the middle rod.

[0022] In order to prevent the air cushion ring 116 from slipping, a first limiting groove (not shown in the figure) is provided on the roller, and the air cushion ring 116 is located in the first limiting groove (not shown in the figure). A second limiting groove 120 matching the air cushion ring 116 is provided on the first sprocket 112.

[0023] In order to facilitate pushing the sliding plate 102 and prevent the nut on the umbrella handle from being damaged, the elastic sliding device includes: at least two slide rails 121 arranged on the frame 101, a slider arranged at the bottom of the sliding plate 102, a first telescopic cylinder 122 arranged on the frame 101, and a fixed seat 123 arranged on the sliding plate 102, the telescopic rod of the first telescopic cylinder 122 passes through the fixed seat 123, and a second spring 124 is sleeved on the telescopic rod of the first telescopic cylinder 122, one end of the second spring 124 is fixedly connected to the fixed seat 123, and the other end is fixedly connected to the end of the telescopic rod of the first telescopic cylinder 122.

[0024] In order to facilitate the positioning of the umbrella handle, the umbrella handle clamping device includes: a mounting plate 125 arranged on the frame 101, a supporting device arranged on the mounting plate 125 for placing the umbrella handle, and a positioning device arranged on the mounting plate 125 for positioning the umbrella handle.

[0025] In order to facilitate the user to place the umbrella handle without affecting the operation of the positioning device, the supporting device includes: an avoidance groove 126 opened on the mounting plate 125, a supporting rod 127 on the mounting plate 125 and located on both sides of the avoidance groove 126, and at least two supporting ropes 128 arranged between the supporting rods 127.

[0026] In order to facilitate positioning the umbrella handle at a position corresponding to the middle rod, the positioning device includes: at least three second telescopic cylinders 129 evenly distributed on the mounting plate 125, an arc block 130 arranged on the telescopic rod of the second telescopic cylinder 129, and a buffer block 131 arranged on the arc block 130.

[0027] Working principle: When in use, first place the umbrella handle on the supporting rope 128, then start the second telescopic cylinder 129, and then control the arc block 130 to move toward the umbrella handle at the same time, so as to position the umbrella handle at the position corresponding to the center of the drum 104, thus completing the positioning of the umbrella handle; Then, the middle rod with the umbrella cloth and ribs installed is inserted into the drum 104. At this time, the middle rod is pushed open by the chamfer 106 to smoothly push open the arc-shaped clamping block 105, so that it is positioned between the three arc-shaped clamping blocks 105 and corresponds to the umbrella handle. Then, the first telescopic cylinder 122 is started, pushing the sliding plate 102 and the middle rod to connect with the umbrella handle. At this time, the servo motor 111 is started, driving the roller 104 and the middle rod to rotate. Since the telescopic rod of the first telescopic cylinder 122 is connected to the sliding plate 102 through the second spring 124, the sliding plate 102 will gradually slide toward the umbrella handle along with the middle rod during the process of screwing the middle rod into the umbrella handle, thereby preventing the tightening from being affected. After tightening, when the resistance between the middle rod and the umbrella handle exceeds the friction between the air cushion ring 116 and the roller 104, the first rotating gear will idle to prevent damage to the threaded structure. At this time, the user can reset each component and take off the umbrella.
