[0002] In the prior art, in an automatic lock, the main component for realizing the automatic function is the motor control part.

[0003] The motor right-angle steering transmission structure is common, with many implementation methods and very wide applications. Among them, the worm and worm gear is the most common for realizing the vertical transmission of the motor. Although the worm and worm gear transmission structure is simple, due to the self-locking characteristic of the worm and worm gear, it is impossible to rotate the positioning gear manually. In the storage of some important files and special items, the safe generally enters the power-off holding state to ensure the safety of the stored items when the power is off. However, at some special moments, it is necessary to manually intervene to release the locked state to ensure the smooth access of the stored items. Content of the Utility Model

[0004] The embodiment of the utility model provides a manual unlocking automatic opening and closing mechanism and a fuel filter, aiming to achieve the technical effect of being able to manually intervene to release the locked state.

[0005] To achieve the above object, the technical solution adopted by the utility model is:

[0006] In a first aspect, a manual unlocking automatic opening and closing mechanism is provided, which includes a base connection seat, a gear set, a worm reduction motor and an elastic pin assembly. The base connection seat is provided with an installation groove. The gear set includes a driving wheel and a driven wheel. The driven wheel is rotatably arranged in the installation groove, and the driving wheel is in gear engagement with the driven wheel. The power output end of the worm reduction motor is connected to the driving wheel, and the driving wheel and the driven wheel are engaged and driven. The elastic pin assembly is arranged on the base connection seat. The elastic pin has the freedom to adjust along the length direction, and one end of the elastic pin assembly is used for inserting into the driving wheel.

[0007] In a possible implementation manner, a through hole communicating with the installation groove is provided on the side wall of the base connection seat. The elastic pin assembly includes a pin sleeve, a pin and an elastic member. The pin sleeve is fixedly arranged on the side wall of the base connection seat, and the inner cavity of the pin sleeve communicates with the through hole.

And the elastic member is arranged in the inner cavity, the elastic member is sleeved on the outer peripheral side of the pin, one end of the elastic member is in contact connection with the pin, and the other end of the elastic member is in contact connection with the inner cavity.

[0008] In a possible implementation, the driven wheel includes a sector tooth, a mounting seat and a rotating pin shaft. The sector tooth is fixedly connected to the mounting seat, and the mounting seat is rotatably disposed in the mounting groove via the rotating pin shaft.

[0009] In a possible implementation, a limiting protrusion is provided on the mounting seat, and a plug hole is provided on the limiting protrusion.

[0010] Wherein, the insertion hole is used to accommodate the bottom end of the pin.

[0011] In a second aspect, the utility model provides a safe, comprising an automatic opening and closing mechanism with manual unlocking as described in the above embodiment.

[0012] In a possible implementation, one side of the base connection seat is fixedly connected to the safe body, and the manual unlocking automatic opening and closing mechanism further includes an active swing arm, a support arm and a fixed plate.

[0014] In a possible implementation, the safe further includes a linkage unlocking plate, and the linkage unlocking plate is connected to the top end of the pin.

[0015] In a possible implementation manner, the elastic member is a compression spring.

[0016] In a possible implementation, both the active jib and the fixing plate are provided with weight-reducing holes.

[0017] Compared with the prior art, the utility model provides an automatic opening and closing mechanism and a safe that can be manually unlocked. The worm gear reduction motor is started. Since the power output end of the worm gear reduction motor is connected to the driving wheel, and the driving wheel and the driven wheel are gear-engaged for transmission, the driven wheel rotates under the drive of the driving wheel. At the same time, the column pin is in a pop-up state due to the action of the compression spring, and the column pin is plugged into the mounting seat, so that the mounting seat and the base connecting seat are in a locked state. When it is necessary to release the lock, it is only necessary to manually pull the top of the column pin, and the bottom of the column pin is pulled away from the driven wheel, thereby releasing the lock between the driven wheel and the base connecting seat. When the unlocking is completed, the top of the column pin is released, and the column pin rebounds under the elastic force of the elastic member itself, thereby locking the driven wheel and the base connecting seat again, achieving the technical effect of requiring human intervention to release the locked state.

[0036] Please refer to Figure 1 , and now a manual unlocking automatic opening and closing mechanism and a safe provided by the present utility model will be described.

[0037] In the first aspect, please refer to Figure 1 , Figure 2 and Figure 3, provided is a manually unlocked automatic opening and closing mechanism. A manually unlocked automatic opening and closing mechanism includes a base connecting seat 1, a gear set 2, a worm reduction motor 3, and an elastic pin assembly 4. The base connecting seat 1 is provided with an installation groove 11. The gear set 2 includes a driving wheel 21 and a driven wheel 22. The driven wheel 22 is rotatably arranged in the installation groove 11, and the driving wheel 21 is in gear engagement with the driven wheel 22. The power output end of the worm reduction motor 3 is connected to the driving wheel 21, and the driving wheel 21 and the driven wheel 22 are engaged and driven. The elastic pin assembly 4 is arranged on the base connecting seat 1. The elastic pin 42 has a degree of freedom for adjustment along the length direction. One end of the elastic pin assembly 4 is used for inserting into the driving wheel 21.

[0038] Please refer to Figure 2 , Figures 4 to 6 , on the basis of the above embodiment, a through hole 12 communicating with the installation groove 11 is provided on the side wall of the base connecting seat 1. The elastic pin assembly 4 includes a pin sleeve 41, a pin 42, and an elastic member 43. The pin sleeve 41 is fixedly arranged on the side wall of the base connecting seat 1, and the inner cavity of the pin sleeve 41 communicates with the through hole 12. The pin 42 slides through the inner cavity. The bottom end of the pin 42 is in contact connection with the driven wheel 22, and the top of the pin 42 is exposed outside the top end of the pin sleeve 41. And the elastic member 43 is arranged in the inner cavity. The elastic member 43 is sleeved on the outer peripheral side of the pin 42. One end of the elastic member 43 is in contact connection with the pin 42, and the other end of the elastic member 43 is in contact connection with the inner cavity.

[0039] Since the elastic member 43 is arranged in the inner cavity, the elastic member 43 is sleeved on the outer peripheral side of the pin 42, one end of the elastic member 43 is in contact connection with the pin 42, and the other end of the elastic member 43 is in contact connection with the inner cavity. Therefore, under the elastic force of the elastic member 43, the pin 42 is in a popped state. The bottom end of the pin 42 is inserted into the through hole 12, and the bottom end of the pin 42 is connected to the side wall of the driven wheel 22, thereby forming a whole of the driven wheel 22 and the base connecting seat 1.

[0040] When unlocking is required, only need to manually pull the top end of the pin 42. The bottom end of the pin 42 moves away from the driven wheel 22 under the pulling action, so the locking between the driven wheel 22 and the base connecting seat 1 is released. After the unlocking is completed, release the top end of the pin 42, and the pin 42 rebounds under the self-elastic force of the elastic member 43, thereby locking the driven wheel 22 and the base connecting seat 1 again.

[0041] Specifically, the elastic member 43 is a compression spring. A compression spring is a helical spring that bears axial pressure. Since it can bear pressure, both ends can be open type, closed type, flattened or ground. The cross-section of the material it uses is mostly circular, and there are also those made of rectangular and multi-strand steel cables. The springs have equal pitch and variable pitch. The shapes of compression springs include: cylindrical, conical, convex in the middle and concave in the middle, as well as a small number of non-circular and various variants of the tail end, etc., which can be formed according to the design requirements of the product. There is a certain gap between the coils of the compression spring. When subjected to an external load, the spring shrinks and deforms, storing deformation energy.

[0042] Please refer to Figure 2 and Figure 6 Furthermore, an adjusting column is fixedly provided at the top of the pin sleeve 41. The adjusting column is a hollow tubular structure. The pin 42 is inserted into the adjusting column, and the top end of the pin 42 is exposed at the top end of the adjusting column.

[0043] Specifically, please refer to Figure 2 , Figure 5 and Figure 6 The driven wheel 22 includes a sector gear 222, a mounting seat 221 and a rotating pin shaft 223. The sector gear 222 is fixedly connected to the mounting seat 221, and the mounting seat 221 is rotatably arranged in the mounting groove 11 through the rotating pin shaft 223.

[0044] Please refer to Figure 4 Furthermore, a limiting convex portion 224 is provided on the mounting seat 221, and a jack 225 is opened on the limiting convex portion 224. Among them, the jack 225 is used to accommodate the bottom end of the pin 42.

[0045] In the second aspect, the present utility model provides a safe, which includes a manual unlocking automatic opening and closing mechanism as described in the above embodiment.

[0046] Please refer to Figure 1 and Figure 2 Based on the above embodiment, one side of the base connecting seat 1 is fixedly connected to the safe cabinet body. The manual unlocking automatic opening and closing mechanism further includes a driving swing arm 5, a support arm 6 and a fixing plate 7. One end of the driving swing arm 5 is rotatably connected to the base connecting seat 1 through the rotating pin shaft 223, and an installation part for installing the worm reduction motor 3 is provided on the upper part of the driving swing arm 5. One end of the support arm 6 is rotatably connected to the driving swing arm 5; the fixing plate 7 is rotatably connected to the other end of the support arm 6, and the fixing plate 7 is fixedly connected to the safe door body.

[0047] Start the worm reduction motor 3. Since the power output end of the worm reduction motor 3 is connected to the driving wheel 21, and the driving wheel 21 is in meshing transmission with the driven wheel 22, the driven wheel 22 rotates under the drive of the driving wheel 21. At the same time, the pin 42 is in the ejected state under the action of the compression spring, and the pin 42 is inserted into the mounting seat 221, so that the mounting seat 221 and the base connecting seat 1 are in the locked state, and the sector gear 222 is fixedly connected to the mounting seat 221. Therefore, at this time, the sector gear 222, the mounting seat 221, and the base connecting seat 1 are relatively fixed. Driven by the worm reduction motor 3, the whole system finally drives the active swing arm 5 to make a circular motion around the rotating pin 223 through gear transmission. Since the fixing plate 7 is rotatably connected to the other end of the active swing arm 5, and the fixing plate 7 is fixedly connected to the safe door body, the automatic opening and closing of the mechanism is finally realized.

[0048] When the system is powered off, the worm reduction motor 3 is in the self-locking state. The driving wheel 21 is connected to the turbine reduction motor, and the main swing arm is locked. The whole system is in the power-off holding state.

[0049] When unlocking is required, manually intervene to pull the pin 42 to make the pin 42 contract. At this time, the mounting seat 221 and the base connecting seat 1 are released, and the mounting seat 221 is connected to the driven wheel 22, the worm reduction motor 3, and the main swing arm through the sector gear 222 to form a relatively fixed state. By applying an external force, the mounting seat 221 makes a circular motion around the rotating pin 223. The mounting seat 221 drives the sector gear 222, the driving wheel 21, the worm reduction motor 3, and the main swing arm to make a circular motion around the rotating pin 223, and the whole system is released from the locked state.

[0050] Furthermore, the base connecting seat 1 is provided with bolt mounting holes 13 to facilitate the bolt connection between the base connecting seat 1 and the safe cabinet body; the fixing plate 7 is also provided with bolt holes to facilitate the bolt connection between the fixing plate 7 and the safe door body.

[0051] Furthermore, there are multiple automatic opening and closing mechanisms with manual unlocking.

[0052] Please refer to Figure 7 , furthermore, the safe also includes a linkage unlocking plate 8, and the linkage unlocking plate 8 is connected to the top end of the pin 42.

[0053] In one embodiment, the active swing arm 5 and the fixing plate 7 are both provided with weight reduction holes. The design of the weight reduction holes can reduce the self-weight of the active swing arm 5 and the fixing plate 7.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
