[0053] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the utility model can be combined with each other arbitrarily without conflict.

[0054] like Figure 1 , Figure 2 , Figure 3 , Figure 4 The utility model is shown in an embodiment, which discloses a handle lock, including a lock housing body 1, and a lock tongue rod 2 is vertically slidably penetrated through the bottom end of the lock housing body 1. The lock housing body 1 is a hollow cylindrical structure, the lower end position of the inner cavity of the lock housing body 1 is a round hole structure, and the rest of the positions are square hole structures.

[0055] In one embodiment, Figure 1 , Figure 2 As shown, a push rod 3 is vertically slidably connected in the lock housing body 1, and a driving part 4 is provided in the lock housing 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, it can push the lock tongue rod 2 to extend from the lock housing body 1 to achieve the locking control of the handle lock. A return spring 5 is provided in the lock housing body 1, and the return spring 5 is used to push the push rod 3 to retract into the lock housing body 1 to achieve the unlocking control of the handle lock.

[0056] In one embodiment, Figure 2 , Figure 3 As shown, a support hole 6 is provided on the inner wall of the lock housing body 1, and a limit column 7 is slidably connected in the support hole 6, and the sliding direction of the limit column 7 is perpendicular to the sliding direction of the lock tongue rod 2. At the same time, a control part 8 is provided in the lock housing body 1, and the control part 8 is used to control the limit column 7 to slide horizontally.

[0057] When the driving part 4 controls the push rod 3 to push the bolt rod 2 out of the lock housing body 1 and puts the handle lock in a locked state, the control part 8 pushes the limit column 7 out of the support hole 6. At this time, the limit column 7 abuts against the upper end of the bolt rod 2, that is, the limit column 7 can prevent the bolt rod 2 from retracting into the lock housing body 1. Subsequently, the driving part 4 controls the push rod 3 to move upward to a reset state. When the control part 8 pushes the limit column 7 to retract into the support hole 6, the bolt rod 2 can retract into the lock housing body 1 under the action of the reset spring 5 to achieve rapid unlocking of the handle lock.

[0058] In one embodiment, Figure 3 , Figure 4As shown, 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 limit column 7 to retract into the support hole 6. A support cavity 82 is provided inside the lock housing body 1, and the support cavity 82 is communicated with the inner cavity of the lock housing body 1, and the support hole 6 is communicated with the support cavity 82. A control rod 83 is vertically slidably connected in the support cavity 82, and a control ring 84 is fixedly sleeved on the control rod 83, and 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 limit column 7. At the same time, a control part 9 for driving the control rod 83 to move vertically is provided in the support cavity 82.

[0059] When the control part 9 pushes the control rod 83 to move upward (that is, move in a direction away from the lock tongue rod 2), the limiting column 7 extends from the support hole 6 under the action of the control slope 85, and at this time, the limiting column 7 blocks the lock tongue rod 2. When the control part 9 pushes the control rod 83 to move downward (that is, move in a direction toward the lock tongue rod 2), the limiting column 7 retracts into the support hole 6 under the action of the control spring 81.

[0060] In one embodiment, Figure 3 , Figure 4 As shown, the end of the limiting column 7 is integrally formed with a guide fillet 10, and the guide fillet 10 abuts against the control inclined surface 85, so that the limiting column 7 can move smoothly. A limiting ring 11 is fixedly sleeved on the control rod 83, and a limiting groove 12 for the limiting ring 11 to slide is provided on the inner wall of the support cavity 82, so as to limit the sliding distance of the control rod 83.

[0061] In one embodiment, Figure 3 , Figure 4 As shown, the control part 9 includes a control rod 91 hinged in the support cavity 82, and a long control groove 92 is provided on the push rod 3. One end of the control rod 91 abuts against the control rod 83, and the other end is located in the control groove 92. A control spring 93 is provided in the support cavity 82, and the control spring 93 is used to push the control rod 83 to move upward.

[0062] When the push rod 3 moves upward under the action of the driving part 4 and moves to the reset state, the bottom 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 inner wall of the control groove 92, and the other end of the control rod 91 pushes the control rod 83 to move downward.

[0063] In one embodiment, Figure 3 , Figure 4As shown, control arc surfaces 94 are integrally formed at both ends of the control rod 91, one of the control arc surfaces 94 abuts against the end of the control rod 83, and the other control arc surface 94 can abut against the bottom inner wall of the control groove 92, so that the control rod 91 can rotate smoothly.

[0064] In one embodiment, Figure 3 , Figure 4 As shown, a guide slope 13 is integrally formed at one end of the lock tongue rod 2 close to the push rod 3 . When the lock tongue rod 2 extends out of the lock housing body 1 , the limiting column 7 can be smoothly retracted into the supporting hole 6 under the action of the guide slope 13 .

[0065] In one embodiment, Figure 1 , Figure 2 As shown, the driving part 4 includes a driving block 41 fixed to the upper end of the push rod 3, the driving block 41 is rectangular, and is vertically slidably connected to the lock housing body 1. A driving motor 42 is arranged in the lock housing body 1, and a driving screw 43 is coaxially fixedly connected to the output shaft of the driving motor 42, the driving screw 43 passes through the driving block 41 and extends into the push rod 3, and the driving screw 43 is threadedly connected to the driving block 41.

[0066] When the handle lock needs to be locked, the driving motor 42 controls the driving screw 43 to rotate, and the driving block 41 and the push rod 3 move downward, and the lock tongue rod 2 moves downward under the action of the push rod 3, and gradually extends from the lock housing body 1. After the guide slope 13 abuts against the limit column 7, as the lock tongue rod 2 continues to move downward, the limit column 7 retracts into the support hole 6 under the action of the guide slope 13. At this time, the control ring 84 drives the control rod 83 and other components to move downward under the action of the limit column 7 and the control slope 85, and the control spring 93 is compressed and deformed.

[0067] When the lock tongue rod 2 is extended to the locking position, the limit column 7 is separated from the lock tongue 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 limit column 7 is extended from the support hole 6 under the action of the control slope 85, that is, the limit column 7 is lower than the upper end of the lock tongue rod 2 to limit the lock tongue rod 2 from sliding upward. Subsequently, the driving motor 42 controls the driving screw 43 to rotate, and the driving block 41 and the push rod 3 move upward to the reset state. At this time, the bottom inner wall of the control groove 92 abuts against the control rod 91.

[0068] When the handle lock needs to be unlocked, the driving motor 42 controls the driving screw 43 to rotate, and the driving block 41 and the push rod 3 move upward. At this time, the control rod 91 rotates under the action of the inner wall of the bottom side 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 limit column 7 retracts into the support hole 6 under the action of the control spring 81, and then the lock tongue rod 2 quickly retracts into the lock housing body 1 under the action of the reset spring 5 to achieve rapid unlocking of the handle lock.

[0069] In the handle lock of this embodiment, the driving screw 43 only needs to rotate a few times to separate the limit column 7 from the lock tongue rod 2, that is, the lock tongue rod 2 is quickly unlocked. Compared with the prior art in which the lock tongue rod 2 is unlocked by controlling the screw 43 with a screw, the screw needs to rotate a large number of times, the unlocking time of the handle lock is long, the user needs to wait for a long time, and the operation is more convenient and quick.

[0070] Moreover, after the handle lock in this design is locked and the drive screw 43 and other components are reset, the drive motor 42 can be in the off state. However, in the related art, after the bolt rod 2 is pushed out by the screw, the drive motor 42 must be kept on, which easily causes the risk of damage to the drive motor 42.

[0071] In one embodiment, Figure 1 As shown, the driving motor 42 is slidably connected to the lock housing body 1, and an unlocking portion 14 is provided in the lock housing body 1. The unlocking portion 14 is used to control the driving motor 42 to drive the push rod 3 to move upward, that is, to ensure that the limit column 7 is retracted into the support hole 6, and the lock tongue rod 2 can be retracted into the lock housing body 1. This design enables the user to realize emergency unlocking of the handle lock by mechanical means after the driving motor 42 fails, adding an additional safety measure for unlocking the handle lock.

[0072] In one embodiment, Figure 1 As shown, the unlocking part 14 includes a lock core part 141 rotatably connected to the lock housing body 1, that is, after the unlocking key is inserted into the lock hole of the lock core part 141, the unlocking key can control the rotation of the lock core part 141. An unlocking gear 142 is fixedly sleeved on the lock core part 141, and an unlocking rack 143 is fixedly connected to the driving motor 42, and the unlocking rack 143 is meshed with the unlocking gear 142.

[0073] When the user inserts the unlocking key into the lock hole of the lock core part 141 and unlocks the lock core part 141, the unlocking key is rotated to control the lock core 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 limit column 7 and the control rod 83 and other components will move accordingly, so that the lock tongue rod 2 is retracted into the lock shell body 1 to achieve mechanical emergency unlocking.

[0074] It can be seen from the above process that the use of this device can achieve rapid unlocking of the handle lock. Compared with the handle lock in the prior art, this handle lock requires a shorter unlocking time, reducing the user's waiting time, and can achieve emergency unlocking, which can not only improve the operating convenience of the handle lock, but also improve the stability of use.

[0075] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present invention should have the common meanings understood by technicians in the field to which the present invention belongs.
