[0041] The following further describes the present invention in detail with reference to the embodiments of the drawings.

[0042] This embodiment provides a seal locking mechanism configured to be applied to a seal device. Among them, the seal device includes a device housing 1, a pressing member 2, a core bracket 3, a seal carrier 4 and a seal body 5. The pressing member 2 is configured to be slidably arranged on the device housing 1 along the axial direction of the seal device; the core bracket 3 is arranged inside the device housing 1 and can move back and forth along the axial direction of the device housing 1 under the drive of the pressing member 2; the seal carrier 4 is located inside the device housing 1 and is arranged on the core bracket 3; the seal body 5 is located inside the device housing 1 and is arranged on the seal carrier 4. Specifically, see Figures 1 to 7As shown, the seal locking mechanism of this embodiment includes a driven part 6, a driving mechanism 7 and a controller (not shown in the figure) that controls the operation of the driving mechanism. The driven part 6 is configured to be set to the inner side of the device housing 1 and to generate corresponding movements in different directions under the drive of the driving force; the driving mechanism 7 is configured to be fixed to the device housing 1 and located on the inner side of the device housing 1. The driving mechanism drives the driven part 6 to switch the moving direction under control, so as to realize the switching adjustment of the driven part 6 to the tight fitting state between the core bracket 3 and the seal carrier 4 and the switching adjustment of the pressing part 2 to the downward pressing state. For example, the driving mechanism 7 here adopts a driving motor, and the driven part 6 is connected to the driving mechanism 7 in transmission connection; the controller is connected to the driving mechanism and is configured to control the driving mechanism to drive the driven part to switch the moving direction.

[0043] Specifically, see Figures 3 to 7 As shown, in this embodiment, the driven part 6 includes a first controlled matching part 61 and a second controlled matching part 62. The first controlled matching part 61 is configured to move with the driven part to achieve a tight matching state between the seal carrier and the core bracket and release the tight matching state; the second controlled matching part 62 is configured to move with the driven part to achieve a non-depressible state of the pressing part and release the non-depressible state of the pressing part.

[0044] In order to cooperate with the above-mentioned driven part to achieve the adjustment of the tight fitting state between the seal carrier and the core bracket and the adjustment of the downward pressing state of the pressing part, in this embodiment, the above-mentioned seal carrier 4 is provided with a first snap groove 41 for the first controlled fitting part 61 of the driven part 6 to be snapped in and out, and a second snap groove 42 for the first controlled fitting part 61 of the driven part 6 to be snapped in and out; a press lock bracket 11 is provided on the inner side of the device housing 1 of the seal device, and the press lock bracket 11 is fixed to the device housing 1, and the press lock bracket 11 has a lock groove 110 for the second controlled fitting part 62 of the driven part 6 to be snapped in and out.

[0045] Of course, in the seal lock mechanism of this embodiment, the first controlled matching portion 61 of the driven member 6 is configured to switch and adjust between the first buckle groove 41 and the second buckle groove 42 as the driven member reciprocates and rotates after being driven, and the buckle groove 110 of the press lock bracket 11 is an arc-shaped groove. The first buckle groove 41 and the second buckle groove 42 are two groove bodies connected to each other. In this way, the driven member can rotate between the first buckle groove and the second buckle groove by rotating.

[0046] As an implementation of the above-mentioned driven component structure, the driven component 6 in this embodiment is a lock latch, the first controlled matching portion 61 is the latch body of the lock latch, and the second controlled matching portion 62 is the lock tongue of the lock latch, which is configured to perform elastic telescopic movement back and forth along the axial direction of the latch body. For example, seeFigure 7 As shown, the latch body is formed with an inner cavity C. An elastic member 63 that can perform elastic telescopic movement along the axial direction of the inner cavity is arranged in the inner cavity C. The elastic member can be a spring. One end of the elastic member is connected to the locking tongue, and the other end of the elastic member is fixed in the inner cavity. In this way, as long as the locking tongue is subjected to a squeezing force, the locking tongue will move towards the inner side of the inner cavity. On the contrary, when the locking tongue is not subjected to a squeezing force, the locking tongue will move towards the outer side of the inner cavity under the elastic force of the elastic member.

[0047] In order to timely grasp whether the first controlled fitting part of the driven member is correspondingly snapped into the first snap groove and the second snap groove of the stamp carrier, so that the controller can control the driving operation of the driving mechanism according to the snap situation, the stamp locking mechanism of this embodiment further includes a snap state detection device 8 for detecting the snap states of the first controlled fitting part 61 with the first snap groove 41 and the second snap groove 42 respectively. The snap state detection device 8 is connected to the controller. Among them, the snap state detection device 8 is configured to be arranged inside the device housing. Among them, the snap state detection device 8 is preferably arranged above the driven member 6 and at a position between the first snap groove 41 and the second snap groove 42. For example, in this embodiment, the snap state detection device 8 adopts a pressure sensor, and the pressure sensor is arranged at a position above the locking bolt of the driven member 6. In this way, once the locking bolt is not snapped into the first snap groove of the stamp carrier, and is not snapped into the second opening groove of the stamp carrier, and the locking tongue of the locking bolt is not snapped into the locking groove of the pressing lock bracket either, at this time, the locking bolt will press the upper pressure sensor because it is not snapped by any groove body. Then, after the pressure sensor sends the detected pressure signal to the controller, the controller can judge that the driven member at this time is neither snapped with the stamp carrier nor snapped with the pressing lock bracket. Furthermore, the controller can make the stamp device send out a prompt message of not locked.

[0048] Of course, when the driven member 6 stays at a position between the first snap groove 41 and the second snap groove 42, the driven member 6 is below the snap state detection device 8.

[0049] In addition, this embodiment also provides a stamp device applying the above-mentioned stamp locking mechanism. The stamp device includes a device housing 1, a pressing member 2, a core bracket 3, a stamp carrier 4 and a stamp body 5. The pressing member 2 is configured to be slidably arranged on the device housing 1 along the axial direction of the stamp device back and forth; the core bracket 3 is arranged inside the device housing 1 and can move back and forth along the axial direction of the device housing 1 under the drive of the pressing member 2; the stamp carrier 4 is located inside the device housing 1 and is arranged on the core bracket 3; the stamp body 5 is located inside the device housing 1 and is arranged on the stamp carrier 4.

[0050] The following combination with Figures 1 to 9, the working principle of the seal locking mechanism in this embodiment is described as follows:

[0051] (1) When it is necessary to lock the seal carrier in the seal device with the core bracket and it is required that the pressing member cannot move downward in the direction of the lower end of the device housing, the controller controls the driving mechanism to work according to the received instruction, so that the driving mechanism drives the driven member to move in one direction until the first controlled mating portion of the driven member is snapped into the first snap groove of the seal carrier and the second controlled mating portion of the driven member is snapped into the locking groove of the pressing lock bracket. Refer to Figure 8 As shown, since both the driven member and the driving mechanism are arranged on the core bracket, the core bracket and the seal carrier are locked through the driven member at this time, and the core bracket and the pressing lock bracket fixed in the device housing are also locked through the driven member, so that the core bracket and the seal carrier as well as the core bracket and the pressing lock bracket are all in a locked state. Even if a downward pressure is applied to the pressing member in this state, because the core bracket has been locked and cannot move downward, the seal body on the seal carrier will not move downward, resulting in the pressing member being unable to move downward in the direction of the lower end of the device housing;

[0052] (2) When it is necessary to lock the seal carrier in the seal device with the core bracket and it is required that the pressing member can move downward in the direction of the lower end of the device housing, the controller controls the driving mechanism to drive the pressed member to move in the other direction according to the instruction, so that the first controlled mating portion of the driven member is removed from the first snap groove of the seal carrier and is snapped into the second snap groove of the seal carrier, and the second controlled mating portion of the driven member is removed from the locking groove of the pressing lock bracket. Refer to Figure 9 As shown, at this time, the core bracket and the seal carrier are still locked through the driven member, while the locking state between the core bracket and the pressing lock bracket is released. Thus, when a downward pressure is applied to the pressing member in this state, the core bracket is not locked with the pressing lock bracket, and the core bracket can move downward in the direction of the lower end of the device housing along with the pressing member. The core bracket drives the seal carrier to move downward, and then the seal body will also move downward with the seal carrier, so that the seal body can move to the outside of the device housing to cooperate with the subsequent stamping operation;

[0053] (3) When it is necessary to separate and disassemble the seal carrier from the core bracket, the controller controls the driving mechanism to drive the pressed member to move in one direction according to the instruction, so that the first controlled mating portion of the driven member is neither snapped into the first snap groove of the seal carrier nor snapped into the second snap groove of the seal carrier. In this way, the seal carrier and the core bracket are always in an unlocked state, and thus the seal carrier can be separated and disassembled from the core bracket as needed.

[0054] Although the preferred embodiments of the present utility model have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
