Description

Technical Field

[0001] The present invention relates to the technical field of safes, in particular to a self-locking structure of a safe and the safe. Background Art

[0002] The current safe includes a box body and a door panel, a door frame is provided on the box body, the door panel and the door frame are connected in an openable and closable manner, and a locking member is provided between the door panel and the door frame and can be effectively locked in the closed position. One type of safe is a safe with a motor to open the door, and is also provided with a spring, for example, a spring is provided at the door panel hinge. The safe includes a control component (for example, an electric control panel provided on the door panel) and a first motor component. The first motor component includes a motor, a transmission structure and a lock bolt. The motor drives the lock bolt to extend and retract through the transmission structure, so that the control component controls the motor operation of the first motor component to lock and unlock. However, due to the presence of the spring, the safe needs to press the door panel when closing the door, forcing the spring at the door panel hinge to be in a compressed state. In this way, when the door panel and the door frame are in the closed position, the user waits for the first motor component to complete the lock bolt extension action. The lock bolt extension process takes 2 to 3 seconds. At this time, the user needs to keep pressing the door panel, which brings inconvenience to use. If the user has no usage experience, it is easy to cause the customer to be unable to close the door for the first time. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the existing technology and propose a self-locking structure of a safe, which can solve the problem that the existing motor-opening safe requires pressing the door panel for 2-3 seconds to wait for the motor to close the door when closing the door; it also includes a safe, including the self-locking structure of the aforementioned safe.

[0004] Compared with the prior art, the present invention proposes a self-locking structure of a safe, comprising a first motor assembly, a door panel and a door frame, the first motor assembly comprising a first motor, a first transmission mechanism and a lock bolt, the first motor driving the lock bolt to extend and retract through the first transmission mechanism to lock and unlock, and further comprising a second motor assembly and a self-locking mechanism, the second motor assembly comprising a second motor and a second transmission mechanism, the self-locking mechanism comprising a first lock catcher and a second lock catcher, the first lock catcher being mounted on the door panel and the second lock catcher being mounted on the door frame, the second motor, the second transmission mechanism and the first lock catcher being sequentially connected in transmission; when the door panel and door frame need to be closed, the door panel drives the first lock catcher to be locked and connected with the second lock catcher, the first lock catcher is in a locked position to close the door panel and the door frame without having to press the door panel all the time, at which time the first motor drives the lock bolt to lock through the first transmission mechanism to lock the door panel and the door frame; when the door panel and door frame need to be opened, the second motor drives the first lock catcher and the second lock catcher to be unlocked through the second transmission mechanism, the second lock catcher is in an unlocked position, and the first motor drives the lock bolt to unlock through the first transmission mechanism to allow the door panel to be opened from the door frame.

[0005] In some embodiments, it also includes a first elastic member and a limiting member. The first locking member adopts a rotating member. The limiting member and the rotating member can cooperate with each other to prevent return. The second transmission mechanism is connected to the limiting member for transmission. The rotating member is provided with a lock mouth. The rotating member is connected to the first elastic member. The first elastic member can pull the rotating member to rotate. When the door panel drives the first locking member and the second locking member to be locked and connected, the rotating member is hit by the second locking member to rotate so that the second locking member and the lock mouth are engaged and limited. At this time, the first elastic member is stretched and is in a stretched state, and the limiting member prevents the rotating member from reversing and returning. When the second motor drives the limiting member to move through the second transmission mechanism to cancel the non-return cooperation, under the action of the first elastic member, the rotating member reverses and returns to release the limit of the lock mouth on the second locking member.

[0006] In some embodiments, a locking opening is provided on a side of the rotating member close to the second locking member, and a non-return notch is provided on a side of the rotating member away from the second locking member. The non-return notch can be non-returnably matched with the limiting member.

[0007] In some embodiments, the second transmission mechanism includes a slider and a screw, which is connected to the second motor gear transmission, and the screw is threadedly connected to the slider. The second motor can drive the slider back and forth along the axis of the screw through the screw. The reciprocating direction is composed of a first direction and a second direction. When the slider moves along the first direction, the slider is used to drive the limit member to disengage from the non-return notch to cancel the non-return engagement. When the slider moves along the second direction, the slider gives up the movement space of the limit member so that the limit member can re-engage with the non-return notch.

[0008] In some embodiments, the second motor assembly includes a housing, the housing is provided with a slide groove, and the slider cooperates with the slide groove.

[0009] In some embodiments, the slider includes a front and a rear, a partition is provided between the front and the rear, the partition is provided with a threaded hole, and the rear is provided with a receiving opening, the screw passes through the receiving opening and is threadedly connected to the partition, the screw is sleeved with a second elastic member, one end of the second elastic member is sleeved with the axial limit of the screw, and the other end of the second elastic member is against the rear side of the receiving opening.

[0010] In some embodiments, a portion of the screw located on the rear side of the partition is provided with a latch, which sleeves one end of the second elastic member to the axial limiting position of the screw, and the latch is located in the accommodating opening.

[0011] In some embodiments, the front end of the slider is provided with a touch surface for triggering the limit member to disengage from the non-return notch to cancel the non-return fit, and the touch surface is provided with an avoidance portion. When the touch surface triggers the limit member to disengage from the non-return notch, the touch rod of the limit member located on the side of the touch surface can move freely toward the avoidance portion to allow the limit member to completely disengage from the non-return notch.

[0012] In some embodiments, the outlet of the slide groove is provided with a limiting surface, the slider includes a front part and a rear part, and a step surface is provided between the front part and the rear part, and the step surface and the limiting surface are limitedly matched along the extending direction of the slider.

[0013] After adopting the above structure, compared with the prior art, the present invention has the following advantages: a second motor assembly and a self-locking mechanism are added to the technical solution disclosed in the present invention, wherein the self-locking mechanism includes a first lock catch and a second lock catch, the first lock catch is installed on the door panel, and the second lock catch is installed on the door frame. When the door panel and the door frame need to be closed, the door panel drives the first lock catch to be locked and connected with the second lock catch, and the first lock catch is in the locked position to close the door panel and the door frame without pressing the door panel all the time. At this time, the first motor drives the lock bolt to lock through the first transmission mechanism to lock the door panel and the door frame. Due to the setting of the self-locking mechanism, when the door panel and the door frame are closed to each other, the second lock catch is naturally caused. The first lock member and the second lock member are first locked and connected, and then the lock bolt can be locked. The second motor assembly includes a second motor and a second transmission mechanism. When the door panel and the door frame need to be opened, the second motor drives the first lock member and the second lock member to unlock through the second transmission mechanism. The second lock member is in the unlocked position. At this time, the first motor drives the lock bolt to unlock through the first transmission mechanism so that the door panel can be opened from the door frame, or the first motor drives the lock bolt to unlock first through the first transmission mechanism, and then the second motor drives the first lock member and the second lock member to unlock through the second transmission mechanism so that the door panel can be opened from the door frame, or the first motor and the second motor run at the same time, without any particular order.

Therefore, the above terms should not be understood as limiting the present invention.

[0025] The safe includes a box body and a door panel 2, which is connected to the box body in an openable and closable manner. The opening of the box body that cooperates with the door panel 2 can be called a door frame 3. In the specific structure, in order to increase the strength, a frame structure will also be set at the opening of the box body. For example, the frame structure can be made of four rods welded in sequence. Figure 1 To connect the second locking member 8, a square tube is welded to the door frame 3. This square tube connects and supports the second locking member 8. In this example, the second locking member 8 is a plate. The safe disclosed herein is a motor-operated safe and also includes a spring. For example, a spring is provided at the hinge of the door panel 2. When unlocked, the spring automatically opens the door panel 2 to a certain angle upon successful unlocking, thereby facilitating further opening of the door. Since the specific connection structure between the safe body and the door panel 2 is known from the prior art, it will not be described in detail here.

[0026] like Figure 1As shown, the self-locking structure of the present disclosure is installed, which includes a first motor assembly 1, a second motor assembly and a self-locking mechanism. The first motor assembly 1 includes a first motor 4, a first transmission mechanism and a lock bolt 5. The first motor 4 drives the lock bolt 5 to extend and retract through the first transmission mechanism to lock and unlock. The second motor assembly includes a second motor 6 and a second transmission mechanism. The self-locking mechanism includes a first lock catch and a second lock catch 8. The first lock catch is installed on the door panel 2, and the second lock catch 8 is installed on the door frame 3. The second motor 6, the second transmission mechanism, and the first lock catch are sequentially connected in transmission; as shown Figure 3 、 8 As shown, when the door panel 2 and the door frame 3 need to be closed, the door panel 2 drives the first lock member to lock and connect with the second lock member 8. The first lock member is in the locked position to close the door panel 2 and the door frame 3 without pressing the door panel 2 all the time. At this time, the first motor 4 drives the lock bolt 5 to lock through the first transmission mechanism to lock the door panel 2 and the door frame 3. Figure 2 、 7 As shown, when the door panel 2 and the door frame 3 need to be opened, the second motor 6 drives the first lock member and the second lock member 8 to unlock through the second transmission mechanism, and the second lock member 8 is in the unlocked position, and the first motor 4 drives the lock bolt 5 to unlock through the first transmission mechanism so that the door panel 2 can be opened from the door frame 3.

[0027] Figure 7 The direction of the arrow on the surface indicates the direction of movement of the door panel 2 when closing the door. Figure 7 、 8 As shown, the self-locking mechanism includes a first elastic member 9, a limiting member 10, a first locking member adopts a rotating member 7, the limiting member 10 and the rotating member 7 can be matched with each other, the second transmission mechanism is connected to the limiting member 10, the rotating member 7 is provided with a lock 11, the rotating member 7 is connected to the first elastic member 9, and the first elastic member 9 can pull the rotating member 7 to rotate, as shown in FIG. Figure 7 、 8 As shown, when the door panel 2 drives the first lock member and the second lock member 8 to lock, the rotating member 7 is actuated by the second lock member 8 to rotate, causing the second lock member 8 to engage and limit the position with the lock hole 11. At this time, the first elastic member 9 is stretched and in an extended state, and the limit member 10 prevents the rotating member 7 from rotating back. When the second motor 6 drives the limit member 10 through the second transmission mechanism to move and cancel the non-return engagement, the rotating member 7 is reversed under the action of the first elastic member 9 to release the lock hole 11 from limiting the position of the second lock member 8. This structural design makes it easier for users to close the door, and locking is simple and reliable.

[0028] In this example, if Figure 7 As shown, a locking opening 11 is provided on the side of the rotating member 7 close to the second locking member 8 , and a non-return notch 12 is provided on the side of the rotating member 7 away from the second locking member 8 , and the non-return notch 12 can be non-return matched with the limiting member 10 .

[0029] In some embodiments, as Figure 4 As shown, the second transmission mechanism includes a gear set, a slider 13, and a screw 14. The input end of the gear set is connected to the second motor 6, and the output end of the gear set is connected to the screw 14. That is, the screw 14 is connected to the second motor 6 through a gear transmission, and the screw 14 is threadedly connected to the slider 13. The second motor 6 can rotate forward and reverse through the screw 14 to drive the slider 13 back and forth along the axial direction of the screw 14. The reciprocating direction is composed of a first direction and a second direction. When the slider 13 moves in the first direction, the slider 13 is used to drive the limit member 10 out of the check notch 12 to cancel the check engagement. When the slider 13 moves in the second direction, the slider 13 makes room for the limit member 10 to re-engage with the check notch 12. This design achieves high movement precision and is stable and reliable.

[0030] In order to make the slider 13 move back and forth smoothly, Figure 4 、 5 As shown in , 6 , the second motor assembly includes a housing 15 , the housing 15 is provided with a slide groove 16 , and the slider 13 cooperates with the slide groove 16 .

[0031] In some embodiments, as Figure 4 As shown, to further improve performance, for example, to prevent the slider 13 from being loose, the slider 13 includes a front portion and a rear portion, with a partition 17 disposed between the front and rear portions. The partition 17 has a threaded hole, and a receiving opening 18 is disposed at the rear portion. The screw 14 passes through the receiving opening 18 and is threadedly connected to the partition 17. The screw 14 is sleeved with a second elastic member 19, one end of which is sleeved with the screw 14 for axial positioning, and the other end of the second elastic member 19 abuts against the rear side of the receiving opening 18. With this design, the elastic support of the second elastic member 19 reduces the clearance between the slider 13 and the screw 14, which helps reduce noise.

[0032] To simplify assembly, a latch 20 is provided on the portion of the screw rod 14 located behind the partition 17 . The latch 20 axially limits and sleeves one end of the second elastic member 19 with the screw rod 14 . The latch 20 is also located in the accommodating opening 18 .

[0033] In some embodiments, as Figure 5 、 6As shown, the front end of the slider 13 is provided with a contact surface 21 for triggering the stopper 10 to disengage from the check notch 12, thereby canceling the non-return engagement. The contact surface 21 is provided with a relief portion. When the contact surface 21 triggers the stopper 10 to disengage from the check notch 12, the contact rod of the stopper 10 located on the side of the contact surface 21 can freely move toward the relief portion, allowing the stopper 10 to completely disengage from the check notch 12. This design enables rapid unlocking, thereby improving the user experience. Specifically, despite the addition of a second motor assembly and a self-locking mechanism, the time required to open the self-locking mechanism is reduced, thereby avoiding the added time required to open the safe. In this example, the contact surface 21 is an overall slope, the inclination of which provides relief space.

[0034] In order to simply control the extent of extension of the slider 13, a positioning structure is provided. That is, a limiting surface 22 is provided at the outlet of the chute 16. The slider 13 includes a front portion and a rear portion, between which a stepped surface 23 is provided. The stepped surface 23 cooperates with the limiting surface 22 to limit the position of the slider 13 in the extension direction. This design is simple in structure and convenient for production and assembly.

[0035] It should be noted that the self-locking mechanism illustrated in this example is only a specific technical solution. Any other technical solution applicable to the present disclosure can also be applied to the present disclosure, such as the lock tongue retractable mechanism, and how the second motor assembly drives the self-locking mechanism to unlock without affecting the locking of the self-locking mechanism can also be other solutions. Any other technical solution applicable to the present disclosure can also be applied to the present disclosure.

[0036] The control of the first motor 4 and the second motor 6 is conventional technical means and will not be described in detail here.

[0037] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0038] The above description is merely an illustrative embodiment of the present invention, and therefore any equivalent changes or modifications made according to the structure, features and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
