For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Reference Figures 1 to 4 According to the first aspect of the embodiment of the utility model, a sliding door hook lock that is easy to open and close includes a locking mechanism 100 and a handle assembly 200. The locking mechanism 100 is used to be installed on the sliding door. The handle assembly 200 includes a transmission shaft 210 and a handle piece 220. The transmission shaft 210 is transmission-connected to the locking mechanism 100, and the handle piece 220 is connected to the transmission shaft 210. The handle piece 220 is vertically arranged, wherein pushing the handle piece 220 to rotate in the door closing direction can drive the locking mechanism 100 to lock, and pushing the handle piece 220 to rotate in the door opening direction can drive the locking mechanism 100 to unlock. When it is necessary to unlock and open the door, one only needs to push the handle 220 in the direction of opening the door. When the vertically arranged handle 220 is subjected to the horizontal force applied by the user, it can rotate the transmission shaft 210 and drive the locking mechanism 100 to unlock. The horizontal force can also drive the sliding door to slide and open the door. The user only needs to push this action to unlock and open the door. Similarly, it is also true for locking and closing the door. The operation can be simplified and the use is convenient. For disabled people who have no fingers or have limited finger movements, they can also use their arms or other parts to operate.

[0029] Specifically, the locking mechanism 100 can be installed on the side of the sliding door so that it can cooperate with the door frame of the sliding door, and the handle assembly 200 has a transmission shaft 210 of a handle piece 220, and the handle piece 220 is for people to operate. The transmission shaft 210 can be connected to the locking mechanism 100 in a transmission manner, and the locking mechanism 100 is driven to open and close the lock by rotating the handle piece 220, and the handle piece 220 can be set downward, which can facilitate the user to apply a horizontal thrust to the handle, and the applied horizontal thrust can cause the handle piece 220 to rotate, thereby driving the locking mechanism 100 to work. The transmission structure therein is not specifically limited, and the rotation direction of the handle can be set corresponding to the opening and closing direction of the sliding door. In actual use, the lock needs to be opened and closed. When opening the door, it is only necessary to apply a horizontal thrust to the handle piece 220 in the door opening direction. At this time, the handle piece 220 is rotated by the force and can be transmitted to the locking mechanism 100 to unlock. After unlocking, the horizontal thrust can continue to drive the sliding door to slide in the door opening direction. One operation can drive the sliding door to unlock and open the door at the same time. The operation is simple. When the door needs to be closed, the sliding door can be pushed to the position where it is about to be closed, and then a horizontal force in the door closing direction is applied to the handle piece 220. The sliding door leans against the door frame under the horizontal force, and the handle piece 220 is rotated in the other direction to drive the locking mechanism 100 to lock, so that the door can be closed and locked at the same time. The operation is simple. Even users with disabled fingers can use their arms to push the operation. It is easy to use and can also meet the needs of disabled people.

[0030] Reference Figures 1 to 3 In some embodiments of the present invention, the locking mechanism 100 includes a housing 110, a transmission assembly, and at least one hook 130. The hook 130 is rotatably disposed on the housing 110. The transmission assembly is disposed on the housing 110, and the transmission assembly is in transmission connection with the transmission shaft 210. The hook 130 is in transmission connection with the transmission assembly. The transmission shaft 210 can drive the hook 130 to rotate through the transmission assembly. The hook 130 can be rotated outward to hook the door frame to lock the door, and can be rotated inward to retract the hook 130 to unlock the door. The hook 130 can be firmly fixed to the door frame, and the structure is simple and reliable.

[0031] Specifically, the shell 110 can be installed on the sliding door by fasteners, and the transmission assembly and the hook 130 can be installed in the shell 110. The transmission assembly is connected to the transmission shaft 210, and the transmission assembly is also connected to the hook 130. The specific transmission connection method is not specifically limited. The rotation of the transmission shaft 210 can drive the transmission assembly, and the transmission assembly drives the hook 130 to rotate. The hook 130 can be rotated outward to hook the door frame to lock the door, and can be rotated inward to retract the hook 130 to unlock the door. The hook 130 can be firmly fixed to the door frame, and the structure is simple and reliable.

[0032] Reference Figures 2 to 4In some embodiments of the present invention, the hook 130 includes a rotating disk 131 and a hook body 132. The hook body 132 is arranged around the rotating disk 131. The rotating disk 131 has a transmission part 131a around the rotating axis. The transmission assembly is connected to the transmission part 131a to drive the rotating disk 131 to rotate. The hook 130 is driven to rotate by the transmission part 131a, and the structure is simpler and more reliable.

[0033] Specifically, the rotating disk 131 can be pivotally connected to the shell 110, and the hook body 132 is circumferentially arranged on the rotating disk 131. When the rotating disk 131 rotates, the hook body 132 can be rotated out of or into the shell 110 to achieve locking. The transmission part 131a circumferentially arranged on the rotation axis of the rotating disk 131 can be transmitted to the transmission assembly. The transmission assembly drives the transmission part 131a, and the transmission part 131a is subjected to force to generate a rotational torque, so that the rotating disk 131 can rotate. The specific transmission structure of the transmission assembly is not specifically limited here. The hook 130 is driven to rotate by the transmission part 131a. Compared with the prior art, the structure of this embodiment is simpler and more reliable.

[0034] Reference Figures 2 to 4 In some embodiments of the utility model, the hook body 132 includes a first hook portion 132a and a second hook portion 132b, the first hook portion 132a is extended along the radial direction of the rotating disk 131, the second hook portion 132b is arranged at the end of the first hook portion 132a away from the rotating disk 131, and the second hook portion 132b is extended along the rotation direction of the rotating disk 131, and a rounded corner is arranged between the end of the second hook portion 132b and the side wall of the second hook portion 132b close to the rotating disk 131. It can facilitate the operation of unlocking while opening the door, and it can also facilitate the operation of locking while closing the door, making the operation of opening and closing the lock smoother, and can further improve the convenience of operation.

[0035] Specifically, the first hook 132a and the second hook 132b can be an integral structure and can be stamped and formed as a whole. It can be understood that the rotating disk 131 and the hook body 132 can also be an integral structure. The first hook 132a and the second hook 132b form an L-shaped hook body 132. During the outward rotation, the second hook 132b can hook the lock slot of the door frame, thereby realizing the sliding door locking. The end of the second hook 132b can be provided with a rounded corner, and the rounded corner can form a guiding effect with the lock slot of the door frame, which is convenient for the second hook 132b to be inserted into the lock slot and also convenient for the second hook 132b to be separated from the lock slot, which can facilitate the operation of unlocking while opening the door, and can also facilitate the operation of locking while closing the door, so that the operation of opening and closing the lock becomes smoother, which can further improve the convenience of operation.

[0036] Reference Figures 2 to 4 In some embodiments of the present invention, the side wall of the second hook portion 132b away from the rotating disk 131 is in an arc shape. Therefore, the smoothness of unlocking and opening the door can be improved.

[0037] Specifically, when unlocking, when the hook body 132 rotates inward, the arc-shaped outer side wall of the second hook portion 132b can reduce interference with the lock slot of the door frame, making it easier for the hook body 132 to detach from the door frame, thereby improving the smoothness of unlocking and opening the door. At the same time, the lock slot on the door frame can also be set smaller to save costs.

[0038] Reference Figures 2 to 4 In some embodiments of the present invention, the transmission assembly includes a transmission slider 121 and a rotating block 122, the rotating block 122 is arranged around the transmission shaft 210, the transmission slider 121 is slidably connected to the housing 110, the rotating block 122 can drive the transmission slider 121 to slide linearly along the housing 110, the transmission slider 121 is provided with a transmission column 121a, the transmission part 131a includes a transmission groove 131b, the transmission column 121a is inserted into the transmission groove 131b, and the transmission column 121a can drive the rotating disk 131 to rotate. The transmission structure is relatively reasonable.

[0039] Specifically, the transmission shaft 210 can be square, and a square hole can be set in the rotating block 122, or other shapes can be used, which are not specifically limited here. The transmission shaft 210 can be inserted into the rotating block 122 and transmit the rotating block 122. The transmission slider 121 and the housing 110 can be provided with a limited position structure so that they can slide linearly. When the rotating block 122 rotates, it can contact and transmit with the transmission slider 121, thereby converting the rotation into the linear motion of the transmission slider 121. The specific transmission structure is not specifically limited here, and the transmission slider 12 1 can be provided with a transmission column 121a protruding outward, and the transmission part 131a on the rotating disk 131 can be a transmission groove 131b that penetrates. The axis of the transmission column 121a is parallel to the rotation axis of the rotating disk 131. The transmission column 121a can be inserted into the transmission groove 131b. The transmission groove 131b has enough escape space for the transmission column 121a to move. When the transmission column 121a moves up and down, it can slide and cooperate with the inner side wall of the transmission groove 131b to transmit, so that the rotating disk 131 rotates around its axis, thereby driving the hook body 132 to rotate in and out. The above transmission structure is relatively reasonable and can facilitate the transmission of the hook body 132.

[0040] It is understandable that a torsion spring may be further provided between the rotating block 122 and the housing 110 , and after the handle 220 is rotated, the elastic force of the torsion spring may drive the handle 220 to return to the vertical position.

[0041] Reference Figures 2 to 4In some embodiments of the utility model, the housing 110 is provided with a rotating shaft 111, the rotating shaft 111 is passed through the rotating disk 131, the rotating disk 131 can rotate around the rotating shaft 111, and the transmission slider 121 is provided with a limiting slide 121b, the rotating shaft 111 is passed through the limiting slide 121b, so that the transmission slider 121 can slide along the length direction of the limiting slide 121b. Specifically, the rotating shaft 111 can be fixedly arranged in the housing 110, the rotating disk 131 can be pivotally connected with the rotating shaft 111, the rotating disk 131 can rotate around the rotating shaft 111, and the limiting slide 121b of the transmission slider 121 can be set to a long strip shape, the rotating shaft 111 is passed through the limiting slide 121b, and the transmission slider 121 can slide along the linear direction of the limiting slide 121b under the limiting cooperation of the rotating shaft 111, so as to facilitate transmission.

[0042] Reference Figure 2 and Figure 4 In some embodiments of the present invention, the transmission slider 121 is provided with a fan-shaped groove 121c, and the rotating block 122 is provided with a driving arm 122a extending along its radial direction, and the driving arm 122a cooperates with the fan-shaped groove 121c to drive the transmission slider 121 to slide. Specifically, the fan-shaped groove 121c can cooperate with the driving arm 122a of the transmission block to convert the rotation of the rotating block 122 into the linear motion of the transmission slider 121.

[0043] Reference Figures 2 to 4 In some embodiments of the present invention, the transmission slot 131b includes a first slot 131c and a second slot 131d arranged adjacent to each other. When the lock is closed, the transmission column 121a can be engaged with the first slot 131c. When the lock is unlocked, the transmission column 121a can be engaged with the second slot 131d. Specifically, the first slot 131c and the second slot 131d can be arranged in a semi-cylindrical shape. The first slot 131c and the second slot 131d are arranged adjacent to each other. When the transmission slider 121 slides to the uppermost end, it is in the unlocking state. The transmission column 121a slides to engage with the second slot 131d to generate a certain limiting force to limit the sliding of the transmission slider 121 to maintain the unlocking state. When the transmission slider 121 slides to the lowermost end, it is in the locking state. The transmission column 121a slides to engage with the first slot 131c to generate a certain limiting force to maintain the locking state, so that the handle 220 can still maintain the state of the switch lock after returning to its position.

[0044] It is understandable that an elastic member may be provided between the transmission slider 121 and the housing 110 , and the elastic member may drive the transmission slider 121 to slide back to a position, so as to facilitate opening and closing the lock.

[0045] According to the second aspect of the present invention, a sliding door includes a sliding door using the above-mentioned sliding door hook lock that is easy to open and close.
