Technical Field

The invention relates to the technical field of umbrellas, in particular to an umbrella with an expandable umbrella cover.

Background

The existing umbrella is generally designed for single or double use, the size of the rain shielding umbrella cover is certain, the walking speed can be influenced by the large size when the single umbrella is used by two persons, and the umbrella can be forgotten by one person often when the rain falls, so that the condition that the double umbrella is used by two persons appears, but the rain shielding umbrella cover is small and is wet, and the use is inconvenient. In order to adapt to the situation, the umbrella which can freely select whether to expand the umbrella cover according to the situation of using the umbrella by a single person or two persons is designed.

Disclosure of Invention

The invention aims to solve the problems in the background art and provides an umbrella with an expandable umbrella cover.

In order to achieve the purpose, the invention adopts the following technical scheme: an umbrella capable of expanding an umbrella cover comprises an umbrella handle, a slip ring sleeved on the umbrella handle and a fixed umbrella cover arranged at the top end of the umbrella handle, wherein a plurality of first support rods for supporting and fixing the umbrella cover are uniformly arranged on the outer peripheral surface of the slip ring, one end of each first support rod, far away from the slip ring, is fixedly connected with the edge of the fixed umbrella cover, the edge of the fixed umbrella cover is connected with an opening and closing umbrella cover, one side of each first support rod, far away from the slip ring, is provided with a third support rod, the opposite ends of the first support rod and the third support rod are respectively provided with a mounting groove, the mounting grooves are rotatably connected with a pin shaft, the two pin shafts are jointly and fixedly sleeved with a second support rod, one of the pin shafts is movably sleeved with a torsion spring, the two ends of the torsion spring are respectively and fixedly connected with the pin shaft and the inner wall of the mounting groove, an inserting rod penetrates through the third support rod, the lower end of, the tensioning spring is movably sleeved on the inserted rod, two ends of the tensioning spring are respectively abutted and contacted with the third supporting rod and the pulling block, the lower end of the first supporting rod is provided with a slot at a corresponding position of the inserted rod, a first limiting groove in sliding connection with the limiting block is arranged at the port of the slot, the inner peripheral surface of the slot is provided with a ring groove communicated with the two first limiting grooves, and the inner wall of one side of the ring groove, which is close to the third supporting rod, is symmetrically provided with two second limiting grooves.

In the umbrella with the expandable umbrella cover, the length of the first limiting groove is greater than that of the second limiting groove.

In the umbrella with the expandable umbrella cover, the straight line where the two first limiting grooves are located and the straight line where the two second limiting grooves are located are arranged in a perpendicular and crossed mode.

In the umbrella with the expandable umbrella cover, the lower end face of the fixed umbrella cover is uniformly glued and fixed with the plurality of bonding wool tops, the lower end face of the stretched and folded umbrella cover is glued and fixed with the bonding barbed strips at the corresponding positions of the bonding wool tops, and the bonding wool tops and the bonding barbed strips are mutually bonded and matched.

In the umbrella with the expandable umbrella cover, the third support rod is provided with a through hole which is in clearance fit with the inserted rod.

Compared with the prior art, the umbrella with the expandable umbrella cover has the advantages that:

the invention can freely select the unfolding umbrella cover to be folded and fixed at the inner side of the umbrella cover or be unfolded according to the condition of using the umbrella by a single person or two persons, thereby avoiding the conditions that the walking speed is influenced by using the umbrella by a single person and the umbrella can be wetted by two persons, and being more convenient.
