[0002] Traditional automatic opening and closing umbrellas have occupied an increasing share in the market since they were launched more than 20 years ago. Traditional automatic opening and closing umbrellas use buttons to open and close the umbrellas. Pressing the button once opens the umbrella, and pressing the button twice closes the umbrella. The structures inside mostly use rocker type and sliding sleeve type. Due to the error in production and processing, the rocker type rocker is easy to stand up, and the sliding sleeve of the sliding sleeve is easy to slide. There are a certain proportion of safety hazards in the traditional functions, and the operation is inconvenient. When the button is pressed to open and close the umbrella, when the finished product is assembled, the umbrella handle is generally wrapped with a bubble bag and then wrapped with adhesive tape. During transportation, it is easy to touch the button when squeezing the packaging box, causing the umbrella to open and cause damage to the umbrella frame. Consumers also have this hidden danger on the way to purchase, and there is a safety problem. Later, the traditional automatic opening and closing umbrella developed a safe automatic opening and closing umbrella, that is, the umbrella button is pressed down for the first time to open the umbrella, and the umbrella is closed for the second time. However, when the middle rod of the umbrella has not been completely retracted, the user needs to press it down manually. During the pressing process, the umbrella is easy to rebound and hurt people due to the force of the spring, which poses a safety hazard. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a sliding safety umbrella handle and an automatic opening and closing umbrella, which solve the safety hazards in the prior art, such as inconvenient operation, easy accidental touch of buttons, and easy rebound of the umbrella opening spring to injure people.

The outer tube moves toward the top of the outer tube under the push of the umbrella opening spring, so that the middle rod is extended to the umbrella opening state. In this process, the card strip of the triangular hook plate clamps the bullet head in the control tube, and the pull rope of the bullet head is outside. The umbrella ribs are opened under the elongation of the tube, the outer tube straightens the safety rope, and the mainspring is wound up to store force. In this process, the bullet head keeps the linkage device and the ratchet wheel apart. Under the rebound force of the first elastic member, the umbrella opening button seat returns to its initial state, and the sliding button is pushed back to the center position by the umbrella opening button seat. When the umbrella needs to be closed, the sliding button is pushed to press the protrusion of the sliding button against the inclined groove of the umbrella closing button seat, and the closing button seat is pressed to push the umbrella closing button seat to move in the opposite direction of the sliding button, driving the card strip of the triangular hook plate to separate from the card neck of the bullet head, and the bullet head The ribs move toward the top of the outer tube under the rebound effect, and the bullet head detaches from the control tube so that the linkage device jams the ratchet. The middle rod is pressed by hand to shrink the middle rod. During the shrinking process, the linkage device makes the ratchet rotate in one direction, shrinking the middle rod, and the spring pulls the safety rope to reel in the ratchet. The spring always keeps balance with the umbrella opening spring through the safety rope. Under the rebound effect of the second elastic member, the umbrella closing button seat returns to its initial state. When the middle rod is fully retracted, the hose presses against the bullet head to press the bullet head into the control tube, and the card strip of the triangular hook plate is stuck on the neck of the bullet head. At this time, The bullet head cooperates with the linkage device to disengage the linkage device from the ratchet, the spring in the ratchet returns to its natural state, and the buckle block of the outer tube is stuck on the tongue block of the U-shaped hook plate to complete the folding of the umbrella. The entire process of opening and closing the umbrella needs to be realized by pushing the sliding button to prevent safety hazards caused by accidental contact, thereby improving the safety of the umbrella handle, convenient operation, and a smooth umbrella opening process. At the same time, a safety rope is used to maintain the balance between the spring and the umbrella opening spring, so that the middle rod can be stuck wherever the umbrella is folded and stopped, so that the user will not be injured when the umbrella is folded, further improving the safety of the umbrella handle.
