Disclosure of Invention

The utility model aims to provide a novel crank for solving the problems.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides a novel crank, includes crank body, crank female head, first magnetic ring and second magnetic ring, the mounting groove has been seted up in the one end left side of crank body, the right side of crank female head is provided with the card and goes into the installation piece in the mounting groove, just the cross-section of mounting groove and installation piece all is polygonal structure, first magnetic ring is fixed to be set up the bottom of mounting groove, the installation piece is provided with places the chamber, the fixed setting of second magnetic ring is in place the intracavity.

Preferably, the top edge of the mounting block is provided with a first circular arc chamfer towards the inner side, and the notch edge of the mounting groove is provided with a second circular arc chamfer towards the outer side.

Preferably, a third circular arc chamfer is arranged between two adjacent side walls of the mounting block, and a fourth circular arc chamfer is arranged between two adjacent side walls of the mounting groove.

Preferably, the polygonal structure is a regular hexagonal structure.

Preferably, the novel crank handle further comprises a handle, a penetrating mounting hole is formed in the other end of the crank handle body, the handle is arranged on one side of the mounting hole, a mounting cavity is formed in the handle, a screw rod is arranged in the mounting cavity, the screw rod penetrates through the mounting hole and is connected with a nut on the other side of the mounting hole in a matched mode, and a handle cover plate is covered at the opening of the mounting cavity.

After the technical scheme is adopted, compared with the background technology, the utility model has the following advantages:

the utility model provides a novel crank, which is characterized in that a first magnetic ring and a second magnetic ring are respectively arranged on a crank body and a crank main head, so that in the use process, as long as a mounting block is inserted into a mounting groove, the first magnetic ring and the second magnetic ring are attracted to each other to prevent falling, and meanwhile, the cross sections of the mounting block and the mounting groove are of polygonal structures, so that slipping in the rotation process can be prevented in a limited manner no matter the crank body rotates clockwise or anticlockwise, the operation is convenient and fast, the operation in the use process is simplified, and the crank is not easy to damage or lose.

FIG. 1 is a schematic diagram of the structure of the present utility model;

FIG. 2 is an exploded view of the structure of the present utility model;

FIG. 3 is an exploded view of another angular structure according to the present utility model.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

It should be noted that, in the present utility model, terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or positional relationship shown in the drawings, and are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element of the present utility model must have a specific orientation, and thus should not be construed as limiting the present utility model.

Examples

Referring to fig. 1 to 3, the utility model discloses a novel crank, which comprises a crank body 1, a crank main head 2, a first magnetic ring 3 and a second magnetic ring 4, wherein a mounting groove 11 is formed in the left side of one end of the crank body 1, a mounting block 21 clamped into the mounting groove 11 is arranged on the right side of the crank main head 2, the cross sections of the mounting groove 11 and the mounting block 21 are of polygonal structures, the first magnetic ring 3 is fixedly arranged at the bottom of the mounting groove 11, the mounting block 21 is provided with a placing cavity, and the second magnetic ring 3 is fixedly arranged in the placing cavity.

The top edge of the mounting block 21 is provided with a first circular arc chamfer 211 toward the inside, and the 11-notch edge of the mounting groove is provided with a second circular arc chamfer 111 toward the outside. A third circular arc chamfer 212 is arranged between two adjacent side walls of the mounting block 21, and a fourth circular arc chamfer 112 is arranged between two adjacent side walls of the mounting groove 11. Through the cooperation of first circular arc chamfer 211 and second circular arc chamfer 111 for the insertion position bore grow of mounting groove 11, and the insertion position bore of installation piece 21 diminishes, thereby installation piece 21 inserts more easily in the mounting groove 11, and the while is further prevented skidding when rotating through the cooperation of third circular arc chamfer 212 and fourth circular arc chamfer 112.

In this embodiment, the polygonal structure is a regular hexagon structure. The main head of the crank is fixed on the umbrella post of the solar outdoor umbrella through a screw rod, and a gasket is arranged on the left side of the main head 2 of the crank and used for buffering with the umbrella post.

Still include handle 5, the mounting hole 12 that runs through has been seted up to the other end of crank body 1, and handle 5 sets up in one side of mounting hole 12, and has seted up installation cavity 51 on handle 5, is provided with screw 52 in the installation cavity 51, thereby screw 52 passes the nut 53 cooperation of mounting hole 12 and mounting hole 12 opposite side and is connected, thereby fixes handle 5 on crank body 1, and the opening part lid in installation cavity 51 establishes handle cover 54.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
