Description

The present invention relates to the field of umbrellas, and particularly to a three-stage automatic opening / closing umbrella composed of two-stage middle rods.

Umbrellas are the most used items in daily life and have the functions of blocking the wind, avoiding rain, and preventing sunshades. Among them, the folding umbrella is small and convenient for storage, so it is loved by many users. However, early umbrellas can be opened by pushing the bones of the umbrella up to a certain position, but if it suddenly starts to rain, it often gets wet before the umbrella is opened.

Therefore, an umbrella that can be opened automatically by placing a button on the handle and pressing this button has been developed, but it does not have an automatic umbrella closing function. For example, when you try to get on the train, you have to use both hands to put the umbrella in the car, so you will get wet in the rain in this short time. In addition, a three-stage folding umbrella usually has a three-stage center rod, but the center rod sways after being unfolded, and the volume of the center rod is large after it is stowed, which affects the strength and service life of the umbrella. There is the task of giving.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a three-stage automatic opening / closing umbrella composed of a two-stage middle rod.

Preferably, the umbrella bone has a closed umbrella spring.

The operating principle of the present invention is as follows. By pressing the forward rotation button of the button on the head of the umbrella, the motor is rotated forward, and the female screw is rotated forward, the nut of the female screw moves upward along the female screw, and for nut connection. The wire rises and the upper sill rises, and since the outer tube is fixedly connected to the upper sill, the outer tube also rises accordingly, and the middle rod becomes longer. After the middle rod becomes long, the action of the pulling rope causes the lower wheel to move upward, the bone of the umbrella expands, the upper end of the lower wheel touches the lower end of the upper wheel, and the lower wheel moves upward. Instead, due to the action of the pulling rope, the lower wheel slide block compresses the lower wheel slide block spring upward, the lower wheel slide block moves upward, and the lower wheel pulley is a moving pulley, so it is medium. The rod continues to be twice as long, and the middle rod does not lengthen as the lower wheel slide block moves upwards and touches the lower wheel. On the contrary, when the reverse button of the button on the head of the umbrella is pressed, the motor is reversed, and the female screw is further reversed, the nut of the female screw moves downward along the female screw, and the nut is connected. By lowering the wire and the upper and outer pipes together, the middle rod is shortened. After the middle rod is shortened, the action of the closing umbrella spring causes the potter's wheel to move downward, and the bone of the umbrella fits in, allowing the umbrella to be stored.

Compared with the prior art, the beneficial effects of the present invention are as follows. In the present invention, the middle rod of the three-stage automatic opening / closing umbrella is set to two stages, the lower wheel slide block and the lower wheel slide block spring are arranged in the lower wheel, and the bottom end of the lower wheel slide block spring is lowered. It is connected to the potter's wheel slide block, and the top end of the potter's wheel slide block spring is connected to the potter's wheel. Therefore, the potter's wheel becomes a moving wheel, and even if the potter's wheel cannot move upward, the action of the pulling device allows the potter's wheel slide block to be compressed by the potter's wheel slide block spring, and further upward. It moves and touches the potter's wheel, which keeps the middle rod longer, and when the umbrella is unfolded, the length of the two-tiered middle rod can reach the length of the three-tiered middle rod, and the three-tiered middle rod. By using a two-stage potter's wheel instead of the potter's wheel, the structure of the potter's wheel becomes more stable, and the strength and service life of the potter's wheel are extended. At the same time, when the umbrella is folded, the size of the umbrella bone also shrinks. In addition, in the present invention, a forward / reverse rotation drive device arranged in the head portion of the umbrella is arranged, and the lead screw is rotated forward or backward to move the nut of the female screw up and down along the female screw. Furthermore, the nut connection wire, the upper wheel and the outer pipe are raised and lowered, and the lower wheel is moved up and down by pulling in the forward direction and the reverse direction by the pulling device, and the umbrella is automatically opened and closed. Realize. The present invention has a simple structure, is easy to operate, is convenient to carry, is highly versatile, has high strength of umbrella bone when unfolded, and has a small size of umbrella bone when stored.

The umbrella bone 1 has a closed umbrella spring 11.

The operating principle of the present invention is as follows. By pressing the forward rotation button of the button 84 on the head portion 3 of the umbrella, the motor 81 is rotated in the normal direction, and the female screw 61 is further rotated in the normal direction, so that the nut 62 of the female screw moves upward along the female screw 61. Then, the nut connection wire 63 rises, and the upper wheel 4 rises.Since the outer tube 21 is fixedly connected to the upper wheel 4, the outer tube 21 also rises accordingly, and the middle rod 2 becomes longer. After the middle rod 2 becomes long, the action of the pulling rope 71 causes the lower wheel 5 to move upward, the bone 1 of the umbrella expands, and the upper end of the lower wheel 5 comes into contact with the lower end of the upper wheel 4. The lower wheel 5 does not move upward, and due to the action of the pull rope 71, the lower wheel slide block 51 compresses the lower wheel slide block spring 53 upward, and the lower wheel slide block 51 moves upward, and also. Since the lower wheel pulley 73 is a moving pulley, the middle bar 2 is twice as long and continues to be long, and when the lower wheel slide block 51 moves upward and touches the lower wheel 5, the middle bar 2 becomes longer. It doesn't become. On the contrary, when the reverse button of the button 84 on the head portion 3 of the umbrella is pressed, the motor 81 is reversed, the female screw 61 is further reversed, and the nut 62 of the female screw is downward along the female screw 61. By moving and further lowering the nut connecting wire 63 and the upper armor 4 and the outer tube 21 together, the middle rod 2 becomes shorter. After the middle rod 2 is shortened, the action of the umbrella closing spring 11 causes the lower wheel 5 to move downward, and the umbrella bone 1 is settled so that the umbrella can be stored.

The above description is merely a better embodiment of the present invention and does not limit the present invention.
