The second end of the mechanical rack 4 is movably connected to the moving square box 6, and the mechanical rack 4 can drive the moving square box 6 to move inward under the action of the mechanical lock to pull back the lock pin.

[0034] When the mechanical rack cannot be actuated in the extended position, opening the electronic lock can drive the moving square box to pull back the lock pin or push the lock pin outward. When the electronic rack cannot be actuated in the extended position, opening the mechanical lock can drive the moving square box to pull back the lock pin.

[0035] The mechanical lock is provided with a return mechanism. After the lock pin is pulled back by the key to realize unlocking, the lock pin can be pushed back to realize locking.

[0036] As an option, the second end of the electronic rack is provided with an extension rod I, the extension rod I is sleeved with a spring I, one end of the spring I is fixedly connected to the extension rod I, and the other end of the spring I is fixedly connected to the moving square box.

[0037] Referring to Figures 1-3The mobile square box is provided with a through hole for passing through the extension rod I and the spring I, which has a limiting and protecting effect and prevents the spring I from being radially deformed; the outer end of the spring I is fixed on the extension rod I by a snap spring 70, and the inner end of the spring I is connected with the mobile square box through a stop pin (not shown in the figure); the mobile square box is provided with a pin hole, and the stop pin is arranged in the pin hole and passes through the inner end of the spring I. Of course, the outer end of the spring I can be directly fixed on the outer wall of the spring I, and the inner end of the spring I is fixed on the extension rod I.

[0038] Referring to Figures 1-3 The mobile square box is provided with a through hole for passing through the mechanical rack; the end of the mechanical rack 4 is connected with a stop block 41 in a bolt connection manner.

[0039] The mechanical lock and the electronic lock are installed in a superimposed manner, the electronic rack 5 is located between the bottom plate 3 and the mechanical rack 4, and the mechanical rack 4 and the electronic rack 5 are superimposed and located in the same plane perpendicular to the bottom plate. Of course, the mechanical lock and the electronic lock can also be located in the same plane parallel to the bottom plate.

[0040] Referring to Figures 1-3 The combination lock further includes a power supply box 11 and a control box 10 arranged on the bottom plate; the electronic lock is provided with a power supply and a control circuit; the power supply is built in the power supply box, and the control circuit is built in the control box.

The guide column can be installed on the bottom plate or an application tool, and has a limiting and guiding effect to prevent the lock pin from deviating.

[0042] As described above, the stop block is fixed at the end of the mechanical rack, and the mechanical rack is retracted to drive the mobile square box when the mechanical lock is opened. The extension rod I is fixedly connected with the end of the electronic rack. The spring is sleeved on the extension rod I and is blocked from retreating by the stop pin fixed on the mobile square box. The snap spring is installed on the outer wall of the mobile square box and is sleeved on the inner rod end. The lock pin is fixedly connected with the mobile square box.

[0043] The mobile square box can be controlled by the mechanical rack and the electronic rack respectively. When the mechanical lock is pulled back (unlocked), the mobile square box is pulled back to drive the lock pin to be pulled back to achieve unlocking; at this time, the movement of the mobile square box can compress the spring, and the rebound of the spring can ensure the reset of the mobile square box when the mechanical rack is locked, and can also have a buffering and protecting effect on the rack. After the mechanical lock is reset (locked), the electronic lock is started by using the electronic lock key, and the mobile square box is pulled back and the spring is compressed (having a buffering and protecting effect), and the lock pin is pulled back to achieve unlocking; at this time, since the light rod part of the end of the mechanical rack passes through the mobile square box and is in a completely empty state, it will not interfere with the action of the electronic lock.

[0045] As described above, the linkage unlocking function is achieved by setting the mobile square box, the lock pin can be controlled by the mechanical lock and the electronic lock, and after the lock is closed, the lock pin can still be locked when the mechanical lock and the electronic lock are paralyzed, and moreover, the lock pin can still be pulled back to unlock when the mechanical lock or the electronic lock is paralyzed.

[0046] Embodiment 2

[0047] The difference between this embodiment 2 and the embodiment 1 is the connection structure of the mechanical rack and the mobile square box, which will be described below, and other descriptions can be referred to the aforementioned embodiment 1.

[0048] Referring to Figure 4 , the mobile square box combination lock of this embodiment 2 includes a bottom plate 3, a mechanical lock 1, an electronic lock 2, a mechanical rack 4, an electronic rack 5, a mobile square box 6, a spring I 7, a spring II 71, and a lock pin 8. The first end of the mechanical rack 4 is arranged in the mechanical lock 1, the first end of the electronic rack 5 is arranged in the electronic lock 2, the mechanical lock 1 and the electronic lock 2 are arranged on the bottom plate 3, and the mechanical rack 4 and the electronic rack 5 have the same extension direction. The lock pin 8 is arranged on the mobile square box 6. The second end of the electronic rack 5 is connected with the mobile square box 6 through the spring I 7, and the electronic rack 5 can drive the mobile square box 6 to move inward or outward under the action of the electronic lock, so as to pull back the lock pin or push the lock pin outward. The second end of the mechanical rack 4 is connected with the mobile square box 6 through the spring II 71, and the mechanical rack 4 can drive the mobile square box 6 to move inward or outward under the action of the mechanical lock, so as to pull back the lock pin or push the lock pin outward.

[0049] When the mechanical rack cannot be operated, the electronic lock is opened to drive the mobile square box to pull back the lock pin or push the lock pin outward. When the electronic rack cannot be operated, the mechanical lock is opened to drive the mobile square box to pull back the lock pin or push the lock pin outward.

[0050] As an option, the second end of the electronic rack is provided with an extension rod I, the extension rod I is sleeved with a spring I, one end of the spring I is fixedly connected to the extension rod I, and the other end of the spring I is fixedly connected to the moving square box; the second end of the mechanical rack is provided with an extension rod II, the extension rod II is sleeved with a spring II, one end of the spring II is fixedly connected to the extension rod II, and the other end of the spring II is fixedly connected to the moving square box. Preferably, the spring II has the same structure as the spring I. The connection structure of the mechanical rack and the moving square box can refer to the connection structure of the electronic rack and the moving square box in the foregoing embodiment 1.

[0051] In this embodiment 2, the mechanical lock can automatically reset and close as in embodiment 1, and on this basis, it can also drive the mechanical rack to continue to extend and fix. Of course, preferably, the mechanical lock can be like the electronic lock, in the moving range, the rack can be moved to a certain position and fixed.

[0052] The lock pin has a pull-back state and an extended state, and the spring I and the spring II are between the lock pin and the mechanical rack and the electronic rack. Based on the compressible and stretchable properties of the spring I and the spring II, the length of the corresponding rack is changed by the lock, and the compression and stretching state of the spring I and the spring II is combined to control the lock pin to be pulled back or extended; for example, the extended electronic rack compresses the spring I, at this time the position of the mechanical rack does not change and the stretched spring II is stretched, and the electronic lock continues to drive the electronic rack to act until the lock pin is in the extended state.

[0053] As described above, in this embodiment 2, the linkage unlocking and locking functions are realized by moving the square box combined with the spring structure. When the electronic lock or the mechanical lock is paralyzed in the unlocking state, the corresponding rack cannot be actuated, and the other normal lock can be used for locking and unlocking operation; when the electronic lock or the mechanical lock is paralyzed in the locking state, the corresponding rack cannot be actuated, and the other normal lock can be used for locking and unlocking operation; when the electronic lock or the mechanical lock is paralyzed in the unlocking or locking process (the unlocking or locking operation is not completed), the corresponding rack cannot be actuated, and the other normal lock can be used to continue the locking and unlocking operation.

[0054] Embodiment 3

[0055] On the basis of the foregoing embodiment 1 or embodiment 2, this embodiment 3 illustrates the application of the foregoing moving square box combination lock. Please refer to the moving square box combination lock in the foregoing embodiment 1 and embodiment 2, and the following will take a 650mm diameter manhole cover plate as an example, but the actual application is not limited to this model, all models and specifications of manhole covers and well rings are applicable, and of course it can also be applied to other appliances.

[0056] Please refer to Figures 5-7The structure of the mobile square box combination lock for solving the problem of the failure of the intelligent well lid in this embodiment 3 comprises the well lid plate 13 arranged on the well ring 12 and the mobile square box combination lock. The mobile square box combination lock is installed on the inner wall surface of the well lid plate 13 through the bottom plate. The lock pin can be retracted or extended and moved under the action of the mechanical lock or the electronic lock. When the lock pin is extended and moved, it can be clamped on the well ring.

[0057] As an option, a protective cover is further included in an embodiment. The protective cover is in the shape of a U-shaped cover body. The protective cover is arranged on the inner wall surface of the well lid plate. The protective cover can wrap around the mobile square box and the peripheral trajectory thereof.

[0058] Referring to Figures 5-7 The mobile square box is the core, which is located at the overlapping position of the outer ends of the mechanical teeth and the electronic rack. The lock pin is fixed at any position of the mobile square box. The single guide column plays a horizontal guiding role on the lock pin. The well ring 12 and the handle hole 14 are auxiliary structures of the device. The well ring 12 ensures that the lock pin can be clamped on the well ring when the well lid is lifted, and the well lid cannot be opened. The control box and the power supply box are the lower shell of the control part of the device. The rack protective cover 15 can wrap the entire mechanical movement part of the mobile square box part, thereby protecting the movement components from being damaged by external force and preventing external impact damage.

[0059] The electronic lock and the mechanical lock are close to each other and are located at the left center of the well lid plate (the round cover plate). The two are fastened on the fixed bottom plate on the well lid plate by bolts. The electronic lock is on the left and the mechanical lock is on the right. The mechanical lock is slightly higher than the electronic lock, so that the mechanical rack is located above the electronic rack. The mechanical rack is controlled by the mechanical lock, and the electronic rack is controlled by the electronic lock.

[0060] When the rack connection structure based on embodiment 1 is used, the linkage unlocking function is realized by the mobile square box. When the mechanical rack is in the extended position and cannot act, opening the electronic lock can drive the mobile square box to pull back the lock pin to unlock or push the lock pin out to lock.

[0061] When the rack connection structure based on embodiment 2 is used, the linkage unlocking and locking functions are realized by the mobile square box combined with the spring structure. When the mechanical rack cannot act, opening the electronic lock can drive the mobile square box to pull back the lock pin to unlock or push the lock pin out to lock.

[0062] As described above, the structure is based on the mobile box and spring structure, so that the mechanical lock and the electronic lock realize linkage function, one set of lock is used as the standby of the other set, and complementary functions can be realized. Even if the key of one of the locks is lost or the lock is broken, the other lock can still play the function of opening (unlocking) / opening and closing (unlocking and locking), so as to effectively avoid the failure of the manhole cover and the inability to operate. In this way, the complementary functions of the mechanical lock and the electronic lock can be realized, and the problem of the failure of the entire device caused by the failure of a single lock can be completely solved; and the rack of the two locks is effectively buffered and protected, preventing the failure of the device caused by the failure of the mechanism.

[0063] It should be noted that the orientations or positional relationships indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation.
