Referring to
This arrangement solves the problem of cumbersome replacement of the handle 1 of the safe door, and may reduce the volume occupied by the safe and the probability that the handle 1 is damaged in the process of transporting and carrying the safe.
Referring to
It should be noted that in other embodiments, the positions of the columnar structure 3 and the rotating shaft 2 may be interchanged. That is, the columnar structure 3 may be provided on the handle 1, the hole 4 may be provided on the rotating shaft 2, the columnar structure 3 may also be provided on the rotating shaft 2, and the hole 4 may be provided on the handle 1. “Axial direction” is usually the direction of the rotating central shaft of a cylinder for a cylindrical object, which is the direction common to the central shaft. In this embodiment, “axial direction” specifically refers to the direction of the center shaft of the rotating shaft 2.
With this arrangement, the handle 1 is connected with the rotating shaft 2 in such a way that the cylindrical structure 3 is insert into the hole 4 and then the restriction structure prevents the columnar structure 3 from rotating relative to the hole 4. The columnar structure 3 is pulled out of the hole 4 to separate the handle 1 from the rotating shaft 2. When transporting or the user wants to replace the model of the handle 1, the problem of cumbersome disassembly and assembly of the handle 1 is solved, and the handle 1 is disassembled and then assembled into the container, which may reduce the volume occupied by the safe and reduce the probability that the handle 1 is damaged at the same time.
In a preferred embodiment of this embodiment, the shape of the handle 1 is set to be circular. With this arrangement, it is convenient for the user to rotate the handle 1 when opening the safe door, and the user may perform the operation of opening the safe door by holding any portion of the circle of the handle 1. Of course, in other embodiments, the shape of the handle 1 may also be set as a polygon, a straight shape, or the like.
In this embodiment, the handle 1 and the rotating shaft 2 are connected by a buckle structure. The buckle structure comprises a snap-fitting member and a neck 5, the snap-fitting member is capable of being snap-fit in the neck 5; the neck 5 is provided on the handle 1 and the snap-fitting member is provided on the rotating shaft 2. In some embodiments, the snap-fitting member may be provided as a hanging loop, and the neck 5 may be provided as a hanging position where the hanging loop is hung. When the columnar structure 3 is inserted into the hole 4, the hanging loop is hung on the hanging position to prevent the handle 1 and the rotating shaft 2 from being separated in use. Of course, the buckle structure may also be provided with other structures. After the columnar structure 3 is inserted into the hole 4, this structure can prevent the snap-fitting member and the neck 5 from being separated when the hand grip is in use.
It should be noted that, in other embodiments, the installation positions of the neck 5 and the snap-fitting member may be interchanged. That is, the neck 5 may be provided on the handle 1, and the snap-fitting member is provided on the rotating shaft 2. The neck 5 may also be provided on the rotating shaft 2, and the snap-fitting member is provided on the handle 1.
With this arrangement, when the safe is in use, the columnar structure 3 on the handle 1 is inserted into the hole 4 on the rotating shaft 2. The position between the handle 1 and the rotating shaft 2 is limited by the limiting structure so as to prevent the relative rotation between the handle 1 and the rotation shaft 2 when the handle 1 is rotated. Then, the handle 1 and the rotating shaft 2 are connected through the buckle structure to prevent the handle 1 and the rotating shaft 2 from being separated when in use. Since the rotating shaft 2 is connected with the transmission mechanism of the lock of the safe door, the rotation of the handle 1 drives the rotation shaft 2 to rotate so that the rotating shaft 2 drives the transmission mechanism of the lock to move so as to open the safe door.
Referring to
It should be noted that in a preferred embodiment of this embodiment, the bead 7 is provided as a steel ball, and the elastic member 8 is provided as a spiral spring. Of course, in other embodiments, the bead 7 may also be a resin bead, such as a fluorine plastic bead, etc. The elastic member 8 may also be a plate spring, etc. In this embodiment, the blocking member is a bolt 9, the bolt 9 is provided with an external thread, the limiting hole 6 is provided with an internal thread, and the external thread of the bolt 9 and the internal thread of the limiting hole 6 may cooperate with each other. The bead 7 and the elastic member 8 are limited within the limiting hole 6 by the bolt 9. In other embodiments, the blocking member may also be a pin, etc.
With this arrangement, the assembly and disassembly between the handle 1 and the rotating shaft 2 may be achieved in a plug-push manner, which is convenient in operation. Moreover, the handle 1 may not be easily detached from the rotating shaft 2 due to the action of the buckle structure in use.
In this embodiment, the neck 5 is provided on the columnar structure 3. The neck 5 extends circumferentially along the columnar structure 3 and is wound on the columnar structure 3 in a ring manner. The wall of the neck 5 is provided as an arc matched with the sphere of the bead 7. After the columnar structure 3 is inserted into the hole 4, the bead 7 is just snap-fit in the neck 5. With this arrangement, when the hand grip is in use, the bead 7 is snap-fit in the neck 5, and the handle 1 will not be detached from the rotating shaft 2. When some users want to replace or disassemble the handle 1, the handle 1 may be detached from the rotating shaft 2 only by pulling the handle 1 along the axial direction of the rotating shaft 2 with force. This arrangement solves the problem of cumbersome disassembly and assembly of the handle 1, and may both save the space of the container and reduce the probability that the handle 1 is damaged by disassembling the handle 1 from the safe door in the process of transporting and carrying the safe.
