Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 and 2, an embodiment provides a cabinet door key, including: a body 10, a plurality of connecting shanks 20 and a plurality of key heads 30. The plurality of levers 20 are provided around the outer peripheral side of the body 10, and the plurality of key heads 30 are connected to the ends of the different levers 20 away from the body 10. Wherein, the key head 30 is rotationally connected with the connecting handle 20; and/or, the stem 20 is rotatably coupled to the body 10.

In the above-mentioned cabinet door key, since a plurality of the connecting levers 20 each having the key head 30 are simultaneously provided on the same body 10, one key is structurally provided with different types of key heads 30 at the same time. When the cabinet door is opened by the operation and maintenance personnel overhauling equipment, a plurality of independent keys do not need to be carried, the phenomenon that the keys are large in quantity and inconvenient to carry and are lost is avoided. Meanwhile, the key head 30 can be rotatably arranged on the connecting handle 20, and/or the connecting handle 20 can be rotatably arranged on the main body 10, so that the size of the whole cabinet door key structure can be reduced in a rotating mode, and the cabinet door key structure is further convenient for operation and maintenance personnel to carry.

It should be noted that "the key head 30 is rotatably connected to the connecting handle 20; and/or, the connection handle 20 is rotatably connected with the main body 10 "includes three embodiments that the key head 30 is rotatably connected with the connection handle 20, or the connection handle 20 is rotatably connected with the main body 10, or the key head 30 is rotatably connected with the connection handle 20, and the connection handle 20 is rotatably connected with the main body 10.

Referring to fig. 1, in the present embodiment, the connecting handle 20 is fixedly connected to the main body 10, and the key head 30 is rotatably connected to an end of the connecting handle 20 away from the main body, so that the key head 30 can rotate relative to the connecting handle 20 by rotating the key head 30, thereby reducing the volume of the whole cabinet door key structure.

Referring to fig. 1 and fig. 2, on the basis of the above embodiments, in an embodiment, the cabinet door key further includes a plurality of rotating shafts 40. A connecting hole (not marked in the figure) is arranged at one end of the connecting handle 20 far away from the main body 10, a through hole (not marked in the figure) is arranged at one end of the key head 30 connected with the connecting handle 20, and the rotating shaft 40 is arranged in the connecting hole and the through hole in a penetrating way to enable the key head 30 to be rotatably connected with the connecting handle 20.

When the cabinet door key is used, referring to fig. 1 in particular, since the key head 30 is connected with the connecting handle 20, and the central axes of the key head 30 and the connecting handle 20 connected with the key head are on the same central line, when any one of the key heads 30 is used to open the corresponding cabinet door, the operator can hold the rest of the connecting handles 20 to rotate the key head 30 in use to open the cabinet door.

When the cabinet door key is not used, the connecting handle 20 is provided with the connecting hole, and the key head 30 is provided with the through hole, so that the rotating shaft 40 penetrates through the connecting hole and the through hole, and the key head 30 can rotate relative to the connecting handle 20, so that the size of the whole key structure is reduced, and the cabinet door key is convenient for operation and maintenance personnel to carry.

Specifically, referring to fig. 2, in the present embodiment, the opening directions of the connecting hole on the connecting handle 20 and the through hole on the key head 30 are arranged along the thickness direction of the main body 10. Therefore, when the cabinet door key is horizontally placed on a table top or any table top, the rotating shaft 40 is perpendicular to the table top or any table top, and the key head 30 can horizontally rotate around the connecting handle 20 and parallel to the table top under the action of the rotating shaft 40, so that the size of the cabinet door key is reduced.

Alternatively, in another embodiment, the opening directions of the coupling hole of the coupling handle 20 and the through hole of the key head 30 are vertically arranged in the thickness direction of the main body 10, and the direction of the upper through hole 110 is vertical.
