DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] With reference to FIG. 1, an adjustable buckle lock in accordance with the present invention is provided. The adjustable buckle lock is configured to be mounted on a first locked object A and a second locked object B and then secure the first locked object A and the second locked object B. For example, the first locked object A may be a lid body of a freezer and the second locked object B may be a main body of the freezer. Or, the first locked object A may be a lid body of a sealed jar and the second locked object B may be a main body of the sealed jar. Alternatively, the first locked object A may be a main body and the second locked object B may be a lid body.

[0019] Then please also refer to FIG. 2 to FIG. 4. In this embodiment, the adjustable buckle lock may comprise a hook unit 10, a fixing unit 20, a wrench unit 30, an elastic unit 40, an adjustment assembly 50, and a buckling ring unit 60. The hook unit 10 is configured to be securely mounted on the first locked object A and the fixing unit 20 is configured to be securely mounted on the second locked object B.

[0020] Two ends of the wrench unit 30 are defined as a pivotal end 31 and an operation end 32, respectively. The operation end 32 and the pivotal end 31 are opposite to each other. The pivotal end 31 is pivotally mounted on the fixing unit 20. One end of the elastic unit 40 is securely mounted on the wrench unit 30 and another end of the elastic unit 40 is securely mounted on the fixing unit 20, which forces the wrench unit 30 to rotate toward the fixing unit 20. In this embodiment, the elastic unit 40 may be a torsion spring which is sleeved on a pivotal axle of the fixing unit 20 with respect to the wrench unit 30. The adjustment assembly 50 is mounted on the wrench unit 30 and the buckling ring unit 60 is pivotally mounted on the adjustment assembly 50. Therefore, the adjustment assembly 50 is capable of controlling a distance between the buckling ring unit 60 and the hook unit 10.

[0021] The buckling ring unit 60 selectively hooks on the hook unit 10. When the buckling ring unit 60 does not hook on the hook unit 10, the first locked object A can be detached from the second locked object B or rotated with respect to the second locked object B. When the buckling ring unit 60 hooks on the hook unit 10, the first locked object A and the second locked object B are pulled and sealed by the adjustable buckle lock. With the adjustment assembly 50 controlling the buckling ring unit 60 in location, the distance between the buckling ring unit 60 and the hook unit 10 can be adjusted, and thereby the pulling force which pulls the buckling ring unit 60 to hook the hook unit 10 is adjusted, which ensures the first locked object A and the second locked object B are sealed together by a suitable force.

[0022] In this embodiment, the wrench unit 30 comprises two side walls and two elongation grooves 33. The two side walls are parallel to and spaced apart from each other and the adjustment assembly 50 is located between the two side walls. The two elongation grooves 33 are formed on the two side walls respectively. An extending direction of each one of the elongation grooves 33 is parallel to a moving direction as the buckling ring unit 60 is moved by the adjustment assembly 50. However, the structures are not limited thereto. In other words, the wrench unit 30 may not have said two side walls, or the adjustment assembly 50 may not be located between the two side walls.

[0023] Then please refer to FIG. 5 to FIG. 7. The adjustment assembly 50 may comprise a fixed base 51, a movable component 52, and a pivoting base 53. The fixed base 51 is securely mounted on the wrench unit 30, the movable component 52 is movably mounted on the fixed base 51, and the pivoting base 53 is securely mounted on the movable component 52. The buckling ring unit 60 is pivotally mounted on the pivoting base 53, and when the movable component 52 is moved, the movable component 52 can drive the pivoting base 53 and the buckling ring unit 60 to move, which controls the distance between the buckling ring unit 60 and the hook unit 10.

[0024] In this embodiment, the fixed base 51 may be in a T-shape. Two arm portions of the T-shape are securely mounted on the wrench unit 30 and the movable component 52 is movably mounted on a leg portion of the T-shape. However, a shape of the fixed base 51 is not limited thereto.

[0025] In this embodiment, the pivoting base 53 may be tubular. An axial direction of the pivoting base 53 is perpendicular to a moving direction of the movable component 52. The buckling ring unit 60 is rotatably mounted through the pivoting base 53. Precisely, a portion of the buckling ring unit 60 is mounted in the pivoting base 53, and a length direction of said portion of the buckling ring unit 60 is parallel to the axial direction of the pivoting base 53, and thus the buckling ring unit 60 can pivot about the axial direction of the pivoting base 53 to hook on the hook unit 10 or separate from the hook unit 10. A sectional area of the pivoting base 53 may be C-shaped and said sectional area is perpendicular to the axial direction of the pivoting base 53. An opening of the C-shape is oriented away from the wrench unit 30, which prevents the buckling ring unit 60 detaching from the pivoting base 53. In another embodiment, the structure of the pivoting base 53 is not limited thereto.

[0026] In this embodiment, the movable component 52 may be a screw, a bolt, etc. Therefore, the movable component 52 may comprise a thread and be screwed on the fixed base 51, and thereby, via rotating with respect to the fixed base 51, the movable component 52 is capable of driving the pivoting base 53 and the buckling ring unit 60 to move. Precisely, the movable component 52 may comprise a threaded portion and a head portion. The threaded portion is threaded with the fixed base 51 and mounted through a wall of the pivoting base 53. The head portion is engaged in the pivoting base 53, which restricts the maximum distance between the pivoting base 53 and the fixed base 51. In another embodiment, the shape of the movable component 52 is not limited thereto; for example, the movable component 52 may be a rod with a thread but without said head portion, or an elastic unit without a thread and thus providing the pulling force via resilience.

[0027] Consequently, the moving of the buckling ring unit 60 is controlled by the adjustment assembly 50, and the distance between the buckling ring unit 60 and the hook unit 10 is adjusted correspondingly. Thus the pulling force for the buckling ring unit 60 hooking on the buckling ring unit 60 is adjusted as well, which ensures the first locked object A and the second locked object B are sealed together by a suitable force.

[0028] For example, in this embodiment, after the head portion of the movable component 52 is rotated or an end of the threaded portion which is opposite the head portion is turned by a hex wrench, the threaded portion can be rotated with respect to the fixed base 51. When the movable component 52 and fixed base 51 are rotated with respect to each other, the movable component 52 can be moved with respect to the fixed base 51 easily. Precisely, the head portion of the movable component 52 can drive the pivoting base 53 and the buckling ring unit 60 to move, which adjusts the distance between the buckling ring unit 60 and the hook unit 10. When the distance between the buckling ring unit 60 and the hook unit 10 is changed, the pulling force that the buckling ring unit 60 pulls the hook unit 10 and the fixing unit 20 is changed correspondingly, so a tightening force provided by the adjustable buckle lock of the present invention and exerted on the first locked object A and the second locked object B can be adjusted. Therefore, the first locked object A and the second locked object B can be sealed together by a suitable force. In other words, if the first locked object A is a lid body of a freezer and the second locked object B is a main body of the freezer, the adjustable buckle lock of the present invention is capable of assisting preventing the cooled gas from leaking. Besides, the pulling force can be adjusted via turning the movable component 52, so the operation is fast and convenient. Further, the structure of the adjustment assembly 50 is very simple and easy to manufacture.

[0029] Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
