[0057] Preferred embodiments of the present disclosure
[0058] In order to make the purpose, technical solutions and advantages of the present disclosure more clear and apparent, the embodiments of the present disclosure will be described in detail below with reference to the drawings. It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other arbitrarily without conflict.
[0059] As shown in Figs. 1, 2, 3 and 4, an embodiment of the present disclosure discloses a handle lock, which comprises a lock shell body 1, and a lock tongue rod 2 vertically slidingly arranged at the bottom end of the lock shell body 1. The lock shell body 1 is in a hollow cylindrical structure, and the lower end of the inner cavity of the lock shell body 1 is in a circular hole structure, and the rest positions are in square hole structures.
[0060] In one embodiment, as shown in FIG. 1, FIG. 2, a push rod 3 is connected to the lock shell body 1 vertically, a driving part 4 is arranged in the lock shell body 1, the driving part 4 is used to control the vertical movement of the push rod 3, and after the push rod 3 moves downward, the push rod 3 can push the bolt bar 2 to extend out of the lock shell body 1 to realize the locking control of the handle lock. A reset spring 5 is arranged in the lock shell body 1, and the reset spring 5 is used to push the push rod 3 to retract into the lock shell body 1 to realize the unlocking control of the handle lock.
[0061] In one embodiment, as shown in FIG. 2, FIG. 3, a support hole 6 is arranged on the inner wall of the lock shell body 1, a limiting column 7 is connected to the support hole 6 in a sliding manner, and the sliding direction of the limiting column 7 is perpendicular to the sliding direction of the bolt bar 2. At the same time, a control part 8 is arranged in the lock shell body 1, and the control part 8 is used to control the horizontal sliding of the limiting column 7.
[0062] When the driving part 4 controls the push rod 3 to push the bolt bar 2 to extend out of the lock shell body 1, and the handle lock is in the locked state, the control part 8 pushes the limiting column 7 to extend out of the support hole 6, at this time, the limiting column 7 abuts against the upper end of the bolt bar 2, that is, the limiting column 7 can block the bolt bar 2 from retracting into the lock shell body 1. Then, the driving part 4 controls the push rod 3 to move upward to the reset state. When the control part 8 pushes the limiting column 7 to retract into the support hole 6, the bolt bar 2 can retract into the lock shell body 1 under the action of the reset spring 5 to realize the rapid unlocking of the handle lock.
[0063] In one embodiment, as shown in FIG. 3, FIG. 4, the control part 8 includes a control spring 81 arranged in the support hole 6, and the control spring 81 is used to control the limiting column 7 to retract into the support hole 6. A support cavity 82 is opened in the inside of the lock shell body 1, the support cavity 82 is communicated with the inner cavity of the lock shell body 1, and the support hole 6 is communicated with the support cavity 82. A control rod 83 is connected to the support cavity 82 in a vertical sliding manner, a control ring 84 is fixedly sleeved on the control rod 83, a control inclined surface 85 is integrally formed on the control ring 84, and the control inclined surface 85 abuts against the end of the limiting column 7. At the same time, a pipe control part 9 is arranged in the support cavity 82 to drive the vertical movement of the control rod 83.
[0064] When the pipe control part 9 pushes the control rod 83 to move upward (that is, to move in the direction away from the bolt bar 2), the limiting column 7 extends out of the support hole 6 under the action of the control inclined surface 85, at this time, the limiting column 7 blocks the bolt bar 2. When the pipe control part 9 pushes the control rod 83 to move downward (that is, to move in the direction of the bolt bar 2), the limiting column 7 retracts into the support hole 6 under the action of the control spring 81.
[0065] In one embodiment, as shown in FIG. 3, FIG. 4, the end of the limiting column 7 is integrally formed with a guide round corner 10, and the guide round corner 10 abuts against the control slope 85, so that the limiting column 7 can move smoothly. The control rod 83 is fixedly sleeved with a limiting ring 11, and the inner wall of the supporting cavity 82 is provided with a limiting groove 12 for sliding of the limiting ring 11, so as to limit the sliding distance of the control rod 83.
[0066] In one embodiment, as shown in FIG. 3, FIG. 4, the control part 9 includes a control rod 91 hinged in the supporting cavity 82, and the push rod 3 is provided with an elongated control groove 92, one end of the control rod 91 abuts against the control rod 83, and the other end is located in the control groove 92. The supporting cavity 82 is provided with a control spring 93, and the control spring 93 is used to push the control rod 83 to move upward.
[0067] When the push rod 3 moves upward under the action of the driving part 4 and moves to the reset state, the bottom side inner wall of the control groove 92 abuts against the control rod 91. When the push rod 3 continues to move upward under the action of the driving part 4, one end of the control rod 91 rotates under the action of the bottom side inner wall of the control groove 92, and the other end of the control rod 91 pushes the control rod 83 to move downward.
[0068] In one embodiment, as shown in FIG. 3, FIG. 4, the two ends of the control rod 91 are integrally formed with control arc surfaces 94, one of which abuts against the end of the control rod 83, and the other of which can abut against the bottom side inner wall of the control groove 92, so that the control rod 91 can rotate smoothly.
[0069] In one embodiment, as shown in FIG. 3, FIG. 4, the end of the lock rod 2 close to the push rod 3 is integrally formed with a guide slope 13, and when the lock rod 2 is extended from the lock shell body 1, the limiting column 7 can be smoothly retracted into the supporting hole 6 under the action of the guide slope 13.
[0070] In one embodiment, as shown in FIG. 1, FIG. 2, the driving part 4 includes a driving block 41 fixed to the upper end of the push rod 3, which is rectangular and vertically and slidingly connected with the lock shell body 1. The lock shell body 1 is provided with a driving motor 42, and the output shaft of the driving motor 42 is coaxially and fixedly connected with a driving screw 43, which passes through the driving block 41 and extends into the push rod 3, and is threadedly connected with the driving block 41.
[0071] When it is needed to lock the handle lock, the driving motor 42 is controlled to rotate the driving screw 43, and the driving block 41 and the push rod 3 are moved downward, the lock bolt rod 2 is moved downward under the action of the push rod 3, and gradually extends from the lock shell body 1. When the guide inclined surface 13 abuts against the limiting column 7, with the continuous downward movement of the lock bolt rod 2, the limiting column 7 is retracted into the supporting hole 6 under the action of the guide inclined surface 13. At this time, the control ring 84 drives the control rod 83 and other components to move downward under the action of the limiting column 7 and the control inclined surface 85, and the control spring 93 is compressed and deformed.
[0072] When the lock bolt rod 2 extends to the locked position, the limiting column 7 is separated from the lock bolt rod 2. At this time, the control rod 83 and other components move upward under the action of the control spring 93, so that the limiting column 7 extends from the supporting hole 6 under the action of the control inclined surface 85, that is, the limiting column 7 is below the upper end of the lock bolt rod 2 to limit the upward sliding of the lock bolt rod 2. Subsequently, the driving motor 42 is controlled to rotate the driving screw 43, and the driving block 41 and the push rod 3 are moved upward to the reset state. At this time, the bottom side inner wall of the control groove 92 abuts against the control rod 91.
[0073] When it is needed to unlock the handle lock, the driving motor 42 is controlled to rotate the driving screw 43, and the driving block 41 and the push rod 3 are moved upward. At this time, the control rod 91 rotates under the action of the bottom side inner wall of the control groove 92, and the control rod 91 pushes the control rod 83 to drive the control ring 84 and other components to move downward. At this time, the limiting column 7 is retracted into the supporting hole 6 under the action of the control spring 81, and then the lock bolt rod 2 is quickly retracted into the lock shell body 1 under the action of the reset spring 5, so as to realize the quick unlocking of the handle lock.
[0074] The handle lock in the embodiment can separate the limiting column 7 from the lock bolt rod 2 by rotating the driving screw 43 for a small number of turns, that is, the lock bolt rod 2 quickly completes the unlocking. Compared with the prior art, the lock bolt rod 2 is controlled to be unlocked by a screw, the screw needs to be rotated for a large number of turns, the handle lock takes a long time to unlock, the user needs to wait for a long time, and the operation is more convenient and fast.
[0075] Furthermore, after the handle lock in the design is locked and the driving screw 43 and other components are reset, the driving motor 42 can be in the closed state. However, in the related art, after the lock bolt rod 2 is pushed out by the screw, the driving motor 42 needs to be kept on, which is easy to cause the risk of damage to the driving motor 42.
[0076] In one embodiment, as shown in FIG. 1, the driving motor 42 is slidingly connected with the lock shell body 1, and the lock shell body 1 is provided with an unlocking part 14 for controlling the driving motor 42 to drive the push rod 3 to move upward, that is, to ensure that the limiting column 7 is retracted into the supporting hole 6, and to enable the lock bolt rod 2 to be retracted into the lock shell body 1. This design enables the user to achieve emergency unlocking of the handle lock by mechanical means when the driving motor 42 fails, thereby adding an additional safety measure for unlocking the handle lock.
[0077] In one embodiment, as shown in FIG. 1, the unlocking part 14 includes a lock cylinder part 141 rotatably connected to the lock shell body 1, that is, after the unlocking key is inserted into the lock hole of the lock cylinder part 141, the unlocking key can control the rotation of the lock cylinder part 141. The lock cylinder part 141 is fixedly provided with an unlocking gear 142, and the driving motor 42 is fixedly connected with an unlocking rack 143, and the unlocking rack 143 is engaged with the unlocking gear 142.
[0078] When the user inserts the unlocking key into the lock hole of the lock cylinder part 141 and unlocks the lock cylinder part 141, the unlocking key is rotated to control the lock cylinder part 141 to drive the unlocking gear 142 to rotate, at this time, the unlocking gear 142 controls the unlocking rack 143 to drive the driving motor 42 to move upward, so that the limiting column 7 and the control rod 83 and other components move correspondingly, thereby enabling the lock bolt rod 2 to be retracted into the lock shell body 1, to achieve mechanical emergency unlocking.
[0079] From the above process, it can be seen that the use of the device can achieve quick unlocking of the handle lock. Compared with the handle lock in the prior art, the handle lock requires less unlocking time, reduces the waiting time of the user, and can achieve emergency unlocking, which can improve the operation convenience of the handle lock and improve the use stability.
