In the present example of execution, the number of the locking unit2is not limited, a lock can include 1 or 2 to 3 locking units, the number of locking unit2can be set according to specific circumstances, the locking unit2comprises a lock head22and a lock hook23, as shown inFIG. 18toFIG. 19, the lock head22is disposed inside a lock bracket21, and the lock head22is movable relative to the lock bracket21, and the lock head22is mounted to the target position through the lock bracket21; a hook part is provided on one side of lock head22, and a hook part is also provided on the lock hook23, the lock head22is moved so that the hook23engages or separates from the hook part of the lock head22.

In the present example of execution, a rope pulling mechanism is applied for the force transmitting mechanism, the rope pulling mechanism includes a locking rope31, the locking rope31connects the rotating shaft13with the lock head22; Specifically, the locking rope31connected with the lock head22, and the fastening surface of the lock head22and the lock hook23are parallel to the locking rope31; as shown inFIG. 16, two parallel guiding grooves1301are set in the circumferential direction of the rotary shaft13, after the locking rope31is connected to the lock head22, the two ends of the locking rope31are respectively set in the two guiding grooves1301, the two connecting parts of the two ends of the locking rope31with the two guiding grooves1301are located in the position of same radial direction of the rotating shaft13. The invention set guiding grooves1302on the rotating shaft31, the guiding groove guides the locking rope, and prevents the locking rope31from moving upper and lower in the lock body.

In this example of execution, the lock set on a suitcase of being opened or closed without using a zipper provided by the present invention further includes a self-locking mechanism, the self-locking mechanism is used to lock the toggle1so as to prevent the toggle1from rotating erratically when the lock is not required to be opened, the specific structure of the self-locking mechanism can be described with reference to the one in embodiment 1.

In this example of execution, the lock set on a suitcase of being opened or closed without using a zipper provided by the present invention is installed at the upper corner of the front surface of the suitcase in a sunken way, the rotating surface of the toggle is perpendicular to the plane where the lock hook and lock head is located.

The invention employs a manner in which the locking rope31and the rotary shaft13are matched to each other, when the toggle1drives the rotating shaft13to rotate, because the two ends of the lock rope31are fixed at the position of the same radial direction of the side of the rotating shaft, and the rotating shaft13can drive the locking rope31to move back and forth slightly, then the lock rope31can drive the lock head22slightly move back and forth, so as to realize the buckling or separation of the lock head22and the lock hook23. The degree of freedom of the locking rope31is very high, it can transfer in any direction, so as to select the set position of the lock in the suitcase body, to increase the degree of freedom.

The invention has a novel structure, the set of the lock on the suitcase is very freedom and convenient; the lock set on the front of the suitcase in the sunken way, shape aesthetic, and when shipped the suitcase will not be damaged by the impact; the locking rope own high degree of freedom, the structure arrangement is convenient; the connection structure of the rotating shaft with the locking rope is simple and unique; a toggle is used as the handle for the switch lock, feel good, generous and convenient.

The invention also provides a suitcase which comprises an upper cover and a lower cover which are fastened together, wherein the connection part of the upper cover and the lower cover are provided with a border, the suitcase is further provided with a lock, the lock comprises an operating component1and a locking component, the operating component1and the locking component are connected through a force transmission mechanism, the locking component is provided inside the suitcase border, the operating component1is concavely formed in the outer surface of the suitcase except the border of the suitcase; the locking component comprises a lock head and a locking hook which are respectively arranged on the upper cover and the lower cover of suitcase, for realizing the locking function. The specific structure of the lock may refer to any of the above-described locks, and the description will not be repeated here.

The following is a specific example to further illustrate the suitcase provided by the invention:

Embodiment 1 of Suitcase

Please refer toFIG. 21toFIG. 23, in this example of execution, the operation component1is disposed on the upper surface of the suitcase7, and is disposed in the middle of the upper surface and beside to the front side of the suitcase.

In this example of execution, the shape of the operation component is circular, the operation component1is also provided with a structure which is convenient for manual opening, the structure which is convenient for manual opening is three inward concave structures that arranged in the circular operating component on the outer contour so that it is convenient for manual opening with hand grip.

In this example of execution, a lock core61is further integrated on the operation component1, which is convenient to open and lock with a key.

In this example of execution, the operation component is a spring-loaded structure, the operating component1is recessed on the surface of the suitcase when not in use, and the operating component is pushed out by pressing the operating component1when in use, and then it is unlocked or locked by operation.

In this example of execution, the operating component opens the locking component by rotating.

Please refer toFIG. 24toFIG. 25, a suitcase which provides in this example of execution, unlike the embodiment 1, the operating component is set in an upper middle portion of the front surface of the suitcase7. The remaining technical features are the same as the embodiment 1, and the description will not be repeated here.

Please refer toFIG. 26, a suitcase which provides in this example of execution, unlike the NO. 1 example of execution, the shape of the operation component1and the setting position are different, specifically, the operating component1is recessed to the right side of the front surface of the suitcase, and the operation component1is a strip shape. The operating component1opens a locking component which is matched with the operating component1by toggling. The remaining technical features are the same as the NO. 1 example of execution, and the description will not be repeated here.

In addition to the above examples of execution, the operating component of the lock of the suitcase may be provided in any other suitable shape, and may be provided in any suitable position of the suitcase body, and the mentioned here is non-mandatory limitation.

The optimized examples of execution of this invention disclosed above are only used for the statement of this invention. The optimized examples of execution do not give a detailed statement of all the details, and such examples of execution shall not limit this invention to be merely in the specific mode of execution as stated above. Evidently, it is suitable to make plenty of modifications and changes based on the contents of the instructions. The purpose for the instructions to select and describe those examples of execution specifically is to explain the principle and practical application of this invention in a better way, and to enable the technical personnel in the technical field to comprehend and utilize this invention in a better way. This invention shall be subject to the Claims and its full extent and any equivalent.
