Description

Technical Field

[0001] The invention relates to the technical field of umbrellas, and in particular to a control device for automatically opening and closing an umbrella. Background Art

[0002] An umbrella is a tool for shading from the sun or protecting from rain or snow. When in use, it is held up by hand. Although the main purpose of the umbrella when it was first invented was to block the sun, it is now most commonly used as a tool to block rain on rainy days and is also a tool that people always carry with them when going out. In order to facilitate users to open and close umbrellas, umbrellas that can open and close automatically have appeared on the market. The main structure of the automatic opening and closing umbrella is the control device on the handle, such as Figure 1 The figure shows a control device for automatically opening and closing an umbrella on the market, comprising a main body 1', a socket channel 2' is provided on the main body 1', an inner tube is inserted into the socket channel 2', a pressing plate 3' is provided on the main body 1', a sliding rod 4' is provided on the pressing plate 3', a sliding channel for the sliding rod 4' to pass through is provided on the main body 1', and a first return spring 5' is sleeved on the sliding rod 4' so that the pressing plate 3' can automatically return to its original position after being pressed, and a sliding block 12' is fixedly provided on the pressing plate 3', and the sliding block 12' is slidably arranged on the main body 1'. The inner body 1' is matched with the socket channel 2', the sliding block 12' is provided with a limiting protrusion 8' for limiting the opening of the umbrella, the pressing plate 3' is also provided with an opening and closing block 6' through a torsion spring, a control tube 11' is fixedly provided in the inner tube, and the control tube 11' and the inner tube are located at the opening and closing block. A transverse hole is provided for the opening and closing block to extend into and engage with the buckle 9' in the inner tube. A long hole is also provided at the other end of the control tube 11', and a spring sheet 10' is provided in the long hole. The spring sheet 10' resists the buckle 9' to prevent it from escaping from the transverse hole. Although it can realize automatic opening and closing of the umbrella, its control device has a complicated structure. When pressing downward to open the umbrella, the torsion force of the torsion spring needs to be overcome, resulting in a large pressing force when in use. In addition, since the buckle head is obliquely buckled on the horizontal hole, it is not smooth when sliding, which is not only not conducive to the opening of the umbrella, but also causes the handle to vibrate more. At the same time, the buckle head is positioned by a spring sheet, so that the user needs to use more force to press the pressing plate when closing the umbrella, and more force is needed to overcome the elastic force of the spring sheet when retracting the outer tube, which is very inconvenient for users to use.

[0046] In order to improve the firmness of the main body 1, reinforcing ribs 12 are fixedly provided at both ends of the main body 1.

[0047] Working principle:

[0048] When opening the umbrella, press the sliding block 3, and the sliding block 3 slides inward. At this time, the protrusion 18 is driven to slide inward, and the engagement between the protrusion 18 and the engagement groove of the outer tube is released. Under the action of the elastic return of the internal spring, the outer tube and the middle tube slide upward to open the umbrella. At the same time, the limiting rod 25 on the sliding plate 15 is released from resisting the middle tube, the return spring 5 is reset, driving the sliding plate 15 to slide upward, and sliding to the position where the pushing block 7 on the sliding plate 15 is on the same axis as the L-shaped connecting rod 9. When closing the umbrella, press the sliding block 3 again. The sliding block 3 drives the sliding plate 15 to slide inward. At this time, the pushing block 7 on the sliding plate 15 resists against the L-shaped connecting rod 9 and pushes the L-shaped connecting rod 9 to move inward. The L-shaped connecting rod 9 drives the lower limiting block 24 to slide backward in the first channel, releasing the engagement with the buckle 14. At this time, the pressing spring 23 is compressed. After the buckle 14 is released from the engagement, the pull rope pulls the buckle 14 to slide upward to realize the automatic closing of the external umbrella surface. At this time, after releasing the sliding block 3, the pressing spring 23 drives the L-shaped connecting rod 9 and the lower limiting block 24 to return. Then, manually close the outer tube and the middle tube, so that the engagement groove on the outer tube engages with the protrusion 18, and drives the buckle 14 to slide downward. When pushing open the lower limiting block 24, the pressing spring 23 is compressed, and then the pressing spring 23 is reset, and the lower limiting block 24 engages with the engagement boss on the buckle 14 to complete the closing of the umbrella.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and descriptions only illustrates the principles of the present invention.
