In the description of the present application, it is to be understood that the directions or positional relationships indicated by the directional terms such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc., are generally based on the directions or positional relationships shown in the drawings, and are for convenience of description and simplicity of description only, and in the case of not making a reverse description, these directional terms do not indicate and imply that the device or element being referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore should not be construed as limiting the scope of the present application; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

In the description of the present application, it should be understood that the terms "first", "second", etc. are used to define the components, and are used only for the convenience of distinguishing the corresponding components, and if not otherwise stated, the terms have no special meaning, and thus, should not be construed as limiting the scope of the present application.

In addition, the technical features mentioned in the different embodiments of the present application described below may be combined with each other as long as they do not conflict with each other.

The incubator can insulate an article stored therein, and thus is widely used in the fields of biomedicine and the like. For example, some cryogenic incubators are used to store medical biological samples to maintain the viability of the medical biological samples by providing the medical biological samples with a required cryogenic environment to facilitate medical examination or medical research.

In order to make the thermal insulation box have better sealing performance and prevent internal hot air or cold air from leaking to influence the thermal insulation effect, a packing type lock is usually arranged on the thermal insulation box, and the packing locking function of the packing type lock is utilized to realize tighter locking effect.

However, in the related art, the tightening lock usually realizes the tightening locking function by matching the locking member with the tightening plane, and in this case, a larger locking force needs to be applied to complete the tightening locking process, which is inconvenient to use and affects the efficiency.

To above-mentioned condition, this application provides a tool to lock and tool to lock system to solve insulation can etc. and locked the inconvenient problem of tool to lock on the device.

Fig. 1-9 illustrate exemplary latch systems, latches, and control methods of the present application.

In which figures 1 and 2 show the structure of the lock system.

Referring to fig. 1 and 2, in the present application, a lock system 100 includes a device-to-be-locked 20 and a lock 10.

The locked device 20 includes a first member 201 and a second member 202 to be locked. The first and

second members

201, 202 are movably connected (e.g., rotatably connected) to move between an open position and a closed position for opening and closing. For example, the locked device 20 is an incubator 203, the first member 201 is one of a cabinet 204 and a door 205 of the incubator 203, and the second member 202 is the other of the cabinet 204 and the door 205 of the incubator 203.

The lock 10 is provided on the device to be locked 20, and is used for locking and unlocking the first member 201 and the second member 202.

Fig. 3-9 further illustrate the structure of latch 10.

Referring to fig. 3-9, and in conjunction with fig. 1 and 2, in the present application, a lock 10 includes a first locking device 1, a second locking device 2, and an actuating mechanism 4. The first locking device 1 is provided on the first member 201 of the device to be locked 20, and includes a locking member 12. The second locking device 2 is provided on the second member 202 of the to-be-locked device 20 and includes a urging portion 23, the urging portion 23 being movably provided with respect to the locking member 12 and gradually gripping the locking member 12 during movement in the first direction X with respect to the locking member 12 to achieve locking between the first member 201 and the second member 202. The actuating mechanism 4 is drivingly connected to at least one of the urging portion 23 and the locking member 12 to drive the urging portion 23 to move in the first direction X relative to the locking member 12.

The lock 10 is a compression type lock because the lock 10 has the compression portion 23 and relies on the gradual clamping between the compression portion 23 and the locking member 12 during the movement of the compression portion 23 relative to the locking member 12 in the first direction X to achieve the locking between the first part 201 and the second part 202 of the device 20 to be locked.

The tightening portion 23 is an important component of the tightening lock 10, and generally has a variable dimension characteristic in the first direction X, so that the distance between the locking member 12 and the tightening portion 23 can be reduced from large to small during the movement process along the first direction X relative to the locking member 12, and a loose fit relation between the locking member 12 and the tightening portion 23 is forced, thereby achieving a tightening locking function and achieving a tighter and more reliable locking effect. In some embodiments, the urging portion 23 and the locking member 12 are relatively rotatable to gradually grip by rotating the urging portion 23 relative to the locking member 12 in the first direction X.

Illustratively, referring to fig. 7, the tightening part 23 includes a tightening surface 231. The tightening surface 231 is obliquely arranged along the first direction X, so that the locking piece 12 is gradually tightened by loosening along the tightening surface 231 in the process of moving towards the second direction Y opposite to the first direction X along the tightening surface 231, and finally, tightening connection is formed, tightening locking is realized, and when unlocking is needed, only the tightening surface 231 is required to move along the second direction Y relative to the locking piece 12, so that the tightening connection can be conveniently released by gradually loosening the fit between the tightening surface 231 and the locking piece, and reverse unlocking is realized.

In the related art, the fastening surface 231 is usually a fastening plane (inclined plane), in which case a large force is required to open and close the lock, which is inconvenient and affects efficiency.

In view of the above, in order to improve the convenience of the lock 10, referring to fig. 3 to 9, in the present application, the tightening portion 23 includes the tightening surface 231, but the tightening surface 231 is not a tightening plane any more but a tightening curved surface 232 (see fig. 7 to 9). The tightening curved surface 232 and the tightening plane are a curved surface and a plane with tightening characteristics, respectively. Compare with compeling tight plane, compel tight curved surface 232 not only can compel tight locking based on holistic slope, can also compel tight locking based on the curve change of self, and this not only is favorable to strengthening to compel tight effect, and the reinforcing is compeled tight locking reliability, also is favorable to realizing more gentle compels tight locking process moreover, reduces the required power of switch locking process, reinforcing convenient to use nature, raises the efficiency.

It is thus clear that through making tool to lock 10 have compel tight curved surface 232, and rely on compel tight curved surface 232 for locking piece 12 along the gradual chucking between the first direction X motion in-process and the locking piece 12, compel tight locking, realize being locked the locking between first part 201 and the second part 202 of device 20, can effectively reduce the switch lock hard, promote tool to lock 10's convenient to use nature, thus, can solve insulation can 203 etc. and be locked the awkward problem of the tool to lock on the device 20, effectively improve use experience, improve switch lock efficiency.

To further improve the convenience of the lock 10, referring to fig. 7, in some embodiments, the curved clamping surface 232 is provided with a concave portion 233, and the concave portion 233 is located between two ends of the curved clamping surface 232 along the first direction X. Thus, when the locking member 12 moves to the concave portion 233 relative to the fastening curved surface 232, the acting force between the fastening curved surface 232 and the locking member 12 changes suddenly, for example, during the locking process, when the locking member reaches the concave portion 233, the acting force between the locking member 12 and the fastening curved surface 232 decreases suddenly, for example, during the unlocking process, when the locking member reaches the concave portion 233, the acting force between the locking member 12 and the fastening curved surface 232 increases suddenly, so that it is convenient to determine whether the locking and unlocking is to be completed in the locking and unlocking process, for example, during the locking and unlocking process, whether the reverse unlocking is to be completed can be determined by sensing whether the locking force decreases suddenly, which is beneficial to further improving the convenience of the lock 10 and improving the user experience.

In addition, with continued reference to fig. 7, in some embodiments, the starting end of the urging curved surface 232 in the first direction X is provided with a stopping portion 24 to stop the locking member 12. In this manner, the stopper portion 24 may be utilized to limit the displacement of the locking member 12 relative to the tightening curve 232 to prevent over-tightening.

In the foregoing embodiments, the actuating mechanism 4 may manually and/or automatically drive the tightening curve 232 to move in the first direction X relative to the locking member 12 to achieve a manual and/or automatic tightening locking process.

For example, referring to fig. 1-9, in some embodiments, the actuating mechanism 4 includes a manual drive mechanism 3, and the manual drive mechanism 3 is in driving connection with at least one of the clamping curve 232 and the locking member 12 to manually drive the clamping curve 232 to move relative to the locking member 12 in the first direction X. At the moment, the manual locking and unlocking process can be realized, the structure is simple, the application scene is wide, and the limitation of factors such as electricity is not needed.

For another example, in other embodiments, the actuating mechanism 4 includes an automatic driving mechanism (not shown) which is in driving connection with at least one of the clamping curved surface 232 and the locking member 12 to automatically drive the clamping curved surface 232 to move in the first direction X relative to the locking member 12. At the moment, the locking and unlocking process can be automatically realized, time and labor are saved, and the locking and unlocking device is convenient and efficient. Wherein, as an example, the automatic driving mechanism includes a motor, the motor is in driving connection with at least one of the tightening curved surface 232 and the locking member 12 through a transmission mechanism such as a gear rack, and at this time, the automatic driving mechanism is an electric driving mechanism, so that the locking and unlocking process can be conveniently controlled by controlling the starting and stopping of the motor, the rotation direction of the motor, the rotation speed of the motor and the number of rotation turns of the motor.

For another example, in some embodiments, the actuating mechanism 4 includes both the manual driving mechanism 3 and the automatic driving mechanism, so that one of the manual driving and the automatic driving can be selected to drive the urging curved surface 232 to move along the first direction X relative to the locking member 12 according to actual conditions. At this moment, tool to lock 10 not only can realize that automatic formula compels tight locking process, can also realize that manual formula compels tight locking process, the work flexibility is higher, convenience of customers selects one of manual and automatic compels tight mode according to actual conditions, especially convenient automatic drive mechanism is because of reasons such as outage and under the unable normal operating's condition, utilize manual drive mechanism 3 to carry out the manual switch lock, make under circumstances such as outage, tool to lock 10 still can carry out the switch, be unlikely to unable work, influence is locked device 20's normal use.

Wherein the actuating mechanism 4 can automatically drive the curved urging surface 232 to move in the first direction X relative to the locking member 12 by being in driving connection with at least one of the curved urging surface 232 and the locking member 12, i.e. the actuating mechanism 4 can be in driving connection with only one of the curved urging surface 232 and the locking member 12, or in driving connection with both the curved urging surface 232 and the locking member 12.

As an example, referring to fig. 3 to 9, the actuating mechanism 4 is drivingly connected to the packing surface 232 to drive the packing surface 232 to move in the first direction X relative to the lock 12 by driving the packing surface 232 to move in the first direction X. Based on this, can compel tight curved surface 232 to move, and locking piece 12 is motionless, by compeling tight curved surface 232 in the motion process, guide locking piece 12 to arrive gradually and compel tight curved surface 232 chucking position, realize compeling tight locking process, simple and convenient, it is effectual to compel tightly.

In particular, with continued reference to fig. 3-9, in some embodiments, the second locking device 2 includes a support seat 22 and a mounting seat 21, the mounting seat 21 is configured to be connected to the second member 202, the support seat 22 is movably disposed on the mounting seat 21, the clamping curved surface 232 is disposed on the support seat 22, and the actuating mechanism 4 is in driving connection with the support seat 22 to drive the clamping curved surface 232 to move along the first direction X by driving the support seat 22 to move along the first direction X. Therefore, the support seat 22 is driven by the actuating mechanism 4 to move along the first direction X, so that the forced locking can be realized, and the operation is simple and convenient. The installation seat 21 is provided to facilitate the installation and fixation of the second locking device 2 on the second component 202, so as to facilitate the implementation of the tightening locking function in the case that the second locking device 2 is firmly installed.

More specifically, referring to fig. 3 and 6, in some embodiments, the supporting seat 22 has an inner cavity 221, the fastening curved surface 232 is disposed on an inner wall of the supporting seat 22, the mounting seat 21 includes an insertion portion 212 and a boss 211, the insertion portion 212 is inserted into the inner cavity 221, the boss 211 is connected to an end of the insertion portion 212 away from the supporting seat 22 and is used for being connected with the second member 202, a cross-sectional area of the boss 211 is smaller than a cross-sectional area of the inner cavity 221, so that the inner cavity 221 is opened toward the locking member 12, and the locking member 12 can be inserted into the supporting seat 22 to be matched with the fastening curved surface 232. Based on this, can conveniently realize the cooperation between mount pad 21 and second part 202 and the supporting seat 22, can make things convenient for locking piece 12 to cooperate with forcing curved surface 232 again, prevent to shelter from because of mount pad 21, and influence locking piece 12 and the cooperation of forcing curved surface 232. Wherein, the mounting seat 21 is fixed on the second part 202 by the boss 211, and forms a sleeving relationship with the supporting seat 22 by the inserting part 212, which is not only beneficial to making the structure of the second locking device 2 simpler and more compact, but also convenient to realize the relative rotation between the supporting seat 22 and the mounting seat 21, so that the forced curved surface 232 and the locking member 12 can be forced to lock or unlock reversely by relative rotation.

Wherein, referring to fig. 3, in some embodiments, the portion of the insertion part 212 inserted into the inner cavity 221 is provided with a groove 213. The groove 213 may be used to accommodate the automatic driving mechanism, that is, the groove 213 may provide a mounting space for the automatic driving mechanism so as to implement an automatic tightening function.

When the second locking device 2 comprises a support seat 22 and an installation seat 21, see fig. 3 and 7, in some embodiments at least one of a wear element 73 and a bump element 25 is provided between the support seat 22 and the installation seat 21.

The wear-resistant member 73 is used for reducing friction between the support seat 22 and the mounting seat 21, is disposed between the support seat 22 and the mounting seat 21, and is contacted by the wear-resistant member 73 during relative movement between the support seat 22 and the mounting seat 21. Thus, the contact friction between the supporting seat 22 and the mounting seat 21 can be prevented, so that the normal use of the lock 10 is not affected by the direct contact friction between the supporting seat 22 and the mounting seat 21. For example, direct contact friction between the support seat 22 and the mounting seat 21 may generate powder, may damage a sprayed layer, may cause rust, and may generate loud noise. After the wear-resistant part 73 is arranged, the problems of corresponding powder falling, rusting, high noise and the like can be effectively solved, so that the lockset 10 can realize a safer and smoother working process with low noise.

The bumper 25 is disposed between the supporting seat 22 and the mounting seat 21, and when the supporting seat 22 is moved in place along the first direction X, the supporting seat 22 contacts the mounting seat 21 through the bumper 25. In this way, the support seat 22 and the mounting seat 21 can be prevented from being violently impacted during the operation of the lock 10, which causes problems, and especially, the internal structure of the lock 10 can be prevented from being damaged due to the failure of the lock 10 during the operation.

In addition, referring to fig. 3 and 8-9, in some embodiments, the second locking device 2 includes not only the support seat 22 and the mounting seat 21, but also an end cap 71, the end cap 71 is disposed at an end of the support seat 22 far from the second member 202, and the second locking device 2 further includes at least one of a pressing plate 72 and two connecting members 74.

Referring to fig. 3, the pressing plate 72 is disposed between the end cap 71 and the supporting base 22 and has a through hole 721. The through hole 721 is for a tool to pass through, and the mount 21 and the second member 202 are attached and detached. In this way, the second locking device 2 is easily attached to and detached from the second member 202. When the second locking device 2 needs to be disassembled, the end cap 71 may be removed first, and then the disassembling tool may be extended into the second locking device 2 through the through hole 721 to connect or disassemble the mounting base 21 and the second component 202. The through hole 721 is disposed on the pressing plate 72, but not directly disposed on the end cover 71, which is beneficial to the effect that the through hole 721 can be shielded by the end cover 71, thereby not only providing an attractive appearance, but also preventing the false detachment.

Specifically, referring to fig. 3, in some embodiments, the pressing plate 72 has at least two through holes 721, and the at least two through holes 721 are arranged at intervals along the first direction X. In this way, it is more convenient to disassemble and assemble the second locking device 2, because, when the supporting seat 22 moves to different positions along the first direction X, the disassembling and assembling tool can selectively pass through all the through holes 721 convenient to operate, so as to disassemble and assemble conveniently no matter which position the supporting seat 22 moves to, and this effect is more prominent under the condition that the supporting seat 22 and the mounting seat 21 rotate relatively.

In addition, as can be seen from fig. 3, 8 and 9, the two connecting members 74 are disposed on the end cover 71 and connected to different positions of the supporting seat 22 along the first direction X, so that the two connecting members 74 are alternatively shielded by the mounting seat 21 during the movement of the supporting seat 22 relative to the mounting seat 21 along the first direction X. Therefore, to remove the end cover 71, the supporting seat 22 must be moved to two different positions along the first direction X, so that the two connecting pieces 74 are exposed and not shielded by the mounting seat 21, and the two connecting pieces 74 can be removed successively to remove the end cover 71, thereby being beneficial to preventing the mistaken removal and improving the use safety of the lock 10. Because, if the second locking device 2 is removed by mistake, the end cover 71 cannot be removed after removing one of the connecting pieces 74, and the other connecting piece 74 can be removed to remove the end cover 71 to remove the second locking device 2 by moving the supporting seat 22 to another position along the first direction X so that the other connecting piece 74 is no longer shielded by the mounting seat 21. This anti-tamper function is particularly important for the locked device 20 that is used in a special environment such as a medical incubator.

In order to connect the two connecting members 74 with the supporting seat 22 at different positions along the first direction X, referring to fig. 3, in some embodiments, two connecting holes 75 are formed in the supporting seat 22, the two connecting holes 75 correspond to the two connecting members 74 one by one, and the two connecting members 74 are respectively inserted into the two connecting holes 75 to be connected with the supporting seat 22 at different positions along the first direction X. At the moment, the structure is simple, and the connection is convenient. As an example, referring to fig. 3, the connecting member 74 includes a screw rod 741, and the screw rod 741 passes through the connecting hole 75 and is locked by a nut 742, so as to connect the connecting member 74 to the supporting seat 22. When the removal is required, the nut 742 is removed, and the screw 741 is pulled out from the coupling hole 75, whereby the cap 71 is removed, and the second locking device 2 is removed from the second member 202.

The lock system and its structure shown in fig. 1-9 will be further described below.

As shown in fig. 1-9, in this embodiment, the lock system 100 includes a locked device 20 and a lock 10.

Specifically, as can be seen from fig. 2 and 3, in this embodiment, the base 11 is substantially semicircular, and is mounted to a side surface of the box 204 by a screw (e.g., a bolt) or the like, and is close to the opening of the box 204, so that the first locking device 1 is disposed at the side surface of the box 204 and is close to the opening of the box 204, and the locking piece 12 of the first locking device 1 is conveniently matched with the pressing portion 23 of the second locking device 2 to perform pressing locking. A non-slip pad 76 is arranged between the base 11 and the box body 204 to prevent the base 11 from slipping and enhance the installation firmness.

The locking member 12 is provided on a surface of the base 11 away from the side of the case 204 and projects in a direction away from the case 204 so as to extend into the second locking device 2 to be in contact with the urging portion 23 of the second locking device 2. As shown in fig. 3, in this embodiment, the locking member 12 has a substantially cylindrical shape, and includes a shaft body 13 and a boss 14. The shaft 13 is connected to the base 11. The shaft sleeve 14 is rotatably sleeved outside the shaft body 13. Specifically, as shown in fig. 5, in this embodiment, a bearing 15 is provided between the shaft sleeve 14 and the shaft body 13 so that the shaft sleeve 14 can rotate relative to the shaft body 13. Further, one seal ring 16 (e.g., an O-ring) is provided on each of the axial sides of the sleeve 14. Meanwhile, one end of the shaft body 13, which is far away from the base 11, is provided with a flange 131, the shaft sleeve 14 is located between the flange 131 and the base 11, and a snap spring 17 (for example, an E-shaped snap spring) is arranged between the shaft sleeve 14 and the flange 131 to perform axial limiting. In this way, the locking member 12 is facilitated to cooperate with the tightening portion 23 of the second locking device 2, which is the tightening curved surface 232, to achieve tightening locking. The shaft sleeve 14 is rotatable, so that resistance of the locking piece 12 in the sliding process along the tightening curved surface 231 is reduced, and time and labor are saved.

The second locking device 2 is disposed on the box door 205, and includes a mounting seat 21, a supporting seat 22, an end cap 71, a pressing plate 72, a wear-resistant member 73, and a screw 741. The support seat 22 is provided with a tightening part 23, a stopping part 24 and a collision preventing piece 25.

As can be seen from fig. 2 to 4, in this embodiment, the mounting base 21 is disposed on a side surface of the door 205, so as to mount the second locking device 2 on the side surface of the door 205. Specifically, as shown in fig. 3 and 4, in this embodiment, the mount 21 includes a boss 211 and a socket 212.

Boss 211 is substantially semicircular and is connected to the free end side of door 205 by a fastener such as a bolt to secure mount base 21 and second locking device 2 to the free end side of door 205. In this embodiment, the semicircular convex portion 211, the straight surface of which faces the tightening curved surface 223, has a cross-sectional area smaller than that of the insertion portion 212 and the inner cavity 221, so that the convex portion 211 can escape the locking member 12, so that the locking member 12 can be inserted into the supporting seat 22 to contact with the tightening portion 23 for tightening and locking, and at the same time, the convex portion 211 can also switchably shield two screw rods 741 serving as the connecting member 74 on the end cover 71 to be mentioned later during the rotation of the supporting seat 22, so as to prevent the forcible detachment. As shown in fig. 3, in this embodiment, a non-slip pad 76 is disposed between the boss 211 and the door 205, and an avoiding hole 761 is disposed on the non-slip pad 76 to avoid the locking member 12 and the two screw rods 741 together with the boss 211.

The insertion portion 212 is substantially cylindrical, and is connected to a side of the boss 211 away from the side of the door 205, and protrudes toward the side away from the door 205 to be inserted into the supporting seat 22, so as to cooperate with the supporting seat 22, thereby realizing rotatable connection of the supporting seat 22 relative to the mounting seat 21. In addition, as shown in fig. 3, in this embodiment, a groove 213 is formed at an end of the insertion portion 212 away from the boss 211, and an end of the groove 213 away from the boss 211 is open, so that, as shown in fig. 6, after the insertion portion 212 is inserted into the support seat 22, the first cavity 222 can be enclosed together with the pressing plate 72 and the support seat 22, and provides an installation space for installing other structures such as an automatic driving mechanism. Meanwhile, as can be seen from fig. 3, in this embodiment, the impact prevention member 25 is provided on the insertion portion 212. The anti-collision piece 25 has elasticity, can absorb impact, reduce vibration and reduce noise, and further can reduce the collision strength between the supporting seat 22 and the mounting seat 21 in the process of forced locking or failure, and reduce the risk of damage of parts due to collision.

Supporting seat 22 rotationally sets up on mount pad 21, and compels tight portion 23 and set up on supporting seat 22 for supporting seat 22 can drive and compel tight portion 23 to rotate, in order to realize compeling tight portion 23 for the rotation of locking piece 12, reaches and compels tight locking and reverse unblock purpose.

As shown in fig. 3, in this embodiment, the support base 22 is substantially annular and has an inner cavity 221 for insertion of the plug portion 212. The insertion portion 212 is inserted into the inner cavity 221, so that the support seat 22 is sleeved outside the insertion portion 212 and can rotate. As shown in fig. 6, after the inserting portion 212 is inserted into the supporting seat 22, it forms a first cavity 222 together with the supporting seat 22 and the pressing plate 72, and at the same time, a second cavity 223 is formed between the boss 211 and the inner wall of the supporting seat 22. The second cavity 223 is opened toward the locking member 12 without being shielded by the side of the door 205, so that the locking member 12 can be inserted into the second cavity 223 to be engaged with the packing portion 23.

Also, returning to fig. 3, in this embodiment, a wear-resistant member 73 is disposed between the support seat 22 and the insertion portion 212. Specifically, the ends of the insertion part 212 close to and far from the boss 211 are respectively provided with one wear-resistant piece 73, so that two wear-resistant pieces 73 are arranged between the support seat 22 and the insertion part 212. The two wear-resistant pieces 73 are located between the outer wall of the socket 212 and the inner wall of the support seat 22, so that the socket 212 and the support seat 22 are not in direct contact, but are in contact through the two wear-resistant pieces 73. The support seat 22 and the mounting seat 21 are made of metal material, and the two wear-resistant pieces 73 are made of nylon material. Like this, at supporting seat 22 for the mount pad 21 rotation in-process, two wearing parts 73 can prevent the inner wall of supporting seat 22 and the outer wall direct contact friction of grafting portion 212, and then prevent that friction from arousing between the metal to fall whitewashed, noise and rust scheduling problem, realize more silence, safe and smooth and easy switch lock process.

In this embodiment, as shown in fig. 3, the two wear-resistant members 73 have the same structure and are in the shape of an open ring to form an open ring pad. Providing the wear member 73 as a non-full ring shape with an opening has the advantage that material can be saved and rotational resistance reduced.

The support seat 22 is provided with a packing part 23. As shown in fig. 7, in this embodiment, the tightening portion 23 is a tightening curved surface 232. The tightening curved surface 232 is disposed on the inner wall of the support seat 22 and extends along the circumferential direction of the support seat 22. Along the first direction X, the tightening curved surface 232 is inclined, and the distance between the outer walls corresponding to the support seat 22 is gradually decreased, in other words, along the second direction Y, the distance between the tightening curved surface 232 and the outer wall of the support seat 22 is gradually increased, so that when the tightening curved surface 232 rotates along the first direction X along with the support seat 22, the locking member 12 rotates along the second direction Y relative to the tightening curved surface 232, and then the locking member 12 gradually climbs onto the tightening curved surface 232 and gradually climbs along the tightening curved surface 232 under the guidance of the tightening curved surface 232, the contact between the locking member 12 and the tightening curved surface 232 is gradually loosened from loose, and finally forms a tightening hook, so as to achieve the effect of tightening locking, whereas when the tightening curved surface 232 rotates along the second direction Y along with the support seat 22, the contact between the locking member 12 and the tightening curved surface 232 is gradually loosened, and finally separates from the tightening curved surface 232, so as to achieve the effect of reverse unlocking.

As can be seen from fig. 7, in this embodiment, the starting end of the tightening curved surface 232 in the first direction X (also the end in the second direction Y) is provided with the stopping portion 24. The stopping portion 24 protrudes radially inward relative to the tightening curved surface 232, so that when the tightening curved surface 232 moves in place along the first direction X, the locking member 12 can abut against the stopping portion 24 when reaching the starting end of the tightening curved surface 232 along the first direction X, and is stopped to continue moving relative to the tightening curved surface 232 towards the second direction Y, so as to prevent excessive tightening and structural damage.

Moreover, as shown in fig. 7, in this embodiment, a concave portion 233 is provided between two ends of the fastening curved surface 232, and the concave portion 233 is recessed toward the radial outside, so that whether to lock or not is convenient to feel, and especially, whether to lock or not is convenient to feel by a user in a manual locking and unlocking process. The concave portion 233 is small so as not to stop the sliding of the locking member 12 along the urging curved surface 232.

Returning to fig. 3, in this embodiment, an end of the support base 22 remote from the boss 211 is provided with an end cap 71. The end cover 71 covers the port of the end of the support base 22 away from the boss 211 to close the corresponding port. Meanwhile, a pressing plate 72 is arranged between the end cover 71 and the port of the supporting seat 22. Specifically, as shown in fig. 3 and fig. 8 to 9, in this embodiment, the end cover 71 and the pressing plate 72 are both circular, and two lead screws 741 are provided on the surface of the end cover 71 facing the support base 22, while four through holes 721 are provided on the pressing plate 72.

Here, two lead screws 741, each serving as a connecting member 74, are arranged at intervals in the circumferential direction of the end cover 71, and are located radially outside the pressing plate 72 so as to extend beyond the pressing plate 72 into the support base 22. Correspondingly, two connecting holes 75 are formed in the inner wall of one end, facing the end cover 71, of the supporting seat 22, the two connecting holes 75 are arranged at intervals in the circumferential direction of the supporting seat 22 and correspond to the two lead screws 741 one to one, so that the two lead screws 741 can penetrate out of the two connecting holes 75 respectively and are locked and limited by the nuts 742, connection between the two lead screws 741 and two circumferential positions of the supporting seat 22 is achieved, and the end cover 71 and the two lead screws 741 can rotate together with the supporting seat 22. As shown in fig. 8 and 9, in this embodiment, the two lead screws 741 and the two connection holes 75 are located radially outside the insertion part 212, and the circumferential positions of the two lead screws 741 are configured such that when one of the two lead screws 741 is shielded by the boss 211 of the mount 21, the other lead screw is not shielded by the boss 211 of the mount 21. Thus, by rotating the support base 22, the bosses 211 can be switched to block the ends of the two lead screws 741 facing the second member 202, so that the ends of the two lead screws 741 facing the second member 202 can be switched to be exposed during the rotation of the support base 22, so that the nuts 742 on the two lead screws 741 can be sequentially removed, and the end cap 71 can be removed. In the process of detaching the two lead screws 741, the two lead screws 741 cannot be detached continuously, but the supporting seat 22 needs to be rotated first after one lead screw 741 is detached, so that one end of the other lead screw 741 facing the second component 202 is circumferentially staggered from the boss 211 and exposed, and the other lead screw 741 can be detached, which is beneficial to preventing the mistaken detachment and improving the use safety of the lock 10.

Returning to fig. 3, the four through holes 721 are all used for avoiding the dismounting tool, so as to facilitate dismounting the second locking device 2. As shown in fig. 3, in this embodiment, four through holes 721 are arranged on the pressing plate 72 at intervals along the circumferential direction of the pressing plate 72, so that the four through holes 721 correspond to different circumferential positions, and the disassembling tool can be conveniently disassembled and assembled when the supporting seat 22 rotates to different positions. As shown in fig. 3, in this embodiment, the four through holes 721 are different in shape, such as circular, square and irregular, so as to be more convenient for the second locking device 2 to be assembled and disassembled when the supporting seat 22 rotates to an angle.

The manual driving mechanism 3 is disposed on the second locking device 2, and is used for realizing manual driving of the tightening portion 23 to realize a manual tightening process. As shown in fig. 3 to 9, in this embodiment, the manual driving mechanism 3 is provided on the support base 22 and includes a handle 31. The handle 31 is substantially annular, and both ends of the handle are fixed on the outer wall of the supporting seat 22, so as to fix the manual driving mechanism 3 on the second locking device 2, so that when the handle 31 is rotated, the supporting seat 22 can be driven to rotate, and then the tightening part 23 rotates along the first direction X or the second direction Y relative to the locking part 12, thereby realizing the manual tightening locking or reverse unlocking process. In this embodiment, the handle 31 is rotated 45 ° to complete the forced locking or reverse unlocking.

In order to stably maintain the locking member 12 in the clamping locking position, as shown in fig. 3, in this embodiment, the lock 10 further includes a locking mechanism 9, and the locking mechanism 9 locks after the clamping curved surface 232 moves to a position in the first direction relative to the locking member 12 to prevent the clamping curved surface 232 from being reversely disengaged from the locking member 12. Thus, after the locking piece 12 reaches the forced locking position, the locking mechanism 10 can be started to lock, the displacement of the locking piece 12 is limited, the locking piece 12 is prevented from accidentally leaving the forced locking position, and the purpose of forced positioning is achieved.

The locking mechanism 9 may include a lock tongue and a lock catch which are matched with each other, and the lock tongue may be manually and/or electrically driven to implement a corresponding manual and/or electric tightening positioning process. Specifically, as shown in fig. 3 and 6, in this embodiment, the lock mechanism 9 includes a first lock mechanism 91 and a second lock mechanism 92.

As can be seen from fig. 3 and 6, the first locking mechanism 91 includes a first lock tongue 93 and a first lock catch portion 94, the first lock tongue 93 and the first lock catch portion 94 are both disposed on the second locking device 2, one of the first lock tongue 93 and the first lock catch portion 94 moves along with the curved clamping surface 232, and the other does not move along with the curved clamping surface 232, and after the curved clamping surface 232 moves in place relative to the locking member 12 along the first direction, the first lock tongue 93 is inserted into the first lock catch portion 94 to prevent the curved clamping surface 232 from being disengaged from the locking member 12 in the opposite direction. Specifically, as shown in fig. 3 and 6, in this embodiment, the first latch 93 is disposed on the bracket 77, and the bracket 77 is fixed to the center of the pressure plate 72 such that the first latch 93 is fixed to the pressure plate 72. The first locking portion 94 is disposed on the support base 22 and includes a key cylinder 95 and a stopper 96. The key cylinder 95 extends into the support 22 for insertion of a key 97. The stopper 96 is connected to an end of the lock cylinder 95 located in the support base 22, and is used for cooperating with the first lock tongue 93 for locking. When the lock is used, the key 97 is inserted into the lock cylinder 95, and the key 97 is rotated, so that the lock cylinder 95 drives the stopper 96 to rotate, the stopper 96 and the first lock tongue 93 are clamped, and the supporting seat 22 and the pressing plate 72 are locked together, so that the mounting seat 21 is fixed and does not rotate because the pressing plate 72 is connected with the mounting seat 21, and therefore, after the supporting seat 22 and the pressing plate 72 are locked together by the first locking mechanism 91, the rotation of the supporting seat 22 can be limited, and the locking piece 12 can be stably kept in the forced locking position and cannot be reversely disengaged. It can be seen that the first locking mechanism 91 of this embodiment can achieve the function of tightening and positioning by locking the support seat 22 and the pressing plate 72.

In addition, as can be seen from fig. 3, in this embodiment, the second locking mechanism 92 includes a second lock tongue (not shown), a second locking portion 98 and a third locking portion 99. The second locking tongue and the second locking portion 98 are disposed on the second locking device 2, the third locking portion 99 is disposed on the first locking device 1, and the second locking tongue is inserted into the second locking portion 98 and the third locking portion 99 after the tightening curved surface 232 moves in place relative to the locking member 12 in the first direction, so as to prevent the tightening curved surface 232 from being reversely disengaged from the locking member 12. Specifically, as shown in fig. 3, in this embodiment, the second latch tongue and the second locking portion 98 are disposed on the inner wall of the supporting base 22, the third locking portion 99 is disposed on the base 11, and the locking holes 90 are correspondingly disposed on the second locking portion 98 and the third locking portion 99. After the locking piece 12 is inserted into the supporting seat 22, the third locking portion 99 is also inserted into the supporting seat 22, and when the supporting seat 22 rotates and the locking piece 12 slides along the tightening curved surface 232 to the tightening locking position, the locking hole 90 on the third locking portion 99 is aligned with the locking hole 90 on the second locking portion 98, and the second locking tongue can be inserted into the locking holes 90 on the third locking portion 99 and the second locking portion 98 to lock the first locking device 1 and the supporting seat 22 together, so that the supporting seat 22 can be prevented from continuing to rotate because the first locking device 1 does not rotate, so that the locking piece 12 can be stably kept in the tightening locking position and cannot be reversely disengaged. It can be seen that the second locking mechanism 92 of this embodiment can achieve the tightening positioning function by locking the support seat 22 and the first locking device 1.

It can be seen that, under the action of the first locking mechanism 91 and the second locking mechanism 92, the locking mechanism 9 of this embodiment can realize the double-tightening positioning function by locking the supporting seat 22 to the first locking device 1 and the mounting seat 21. It is understood that the locking mechanism 9 may not only perform double-forced locking, but may also perform single-pass forced locking, for example, in other embodiments, only one of the first locking mechanism 91 and the second locking mechanism 92 may be provided to perform single-pass forced locking.

When the lockset 10 of the embodiment is used, the first locking device 1 and the second locking device 2 can be integrally disassembled and assembled, so that the operation is simple and the maintenance is convenient.

If it is necessary to mount the second locking device 2 on the second member 202, the mounting seat 21, the supporting seat 22 and the pressing plate 72 may be assembled together, then the mounting tool is inserted through the through hole 721 to tighten the fastener connecting the mounting seat 21 and the second member 202, then the end cap 71 is mounted with the door 205 not closed, the two screws 741 on the end cap 71 are inserted through the two connecting holes 75 on the supporting seat 22, then the supporting seat 22 is successively positioned at the positions where the two screws 741 are respectively exposed as shown in fig. 8 and 9, and the two nuts 742 are respectively screwed onto the two screws 741, thereby mounting the entire second locking device 2 on the second member 202.

If the second locking device 2 needs to be detached from the second member 202, when the door 205 is opened, the supporting base 22 is successively positioned at positions where the two screws 741 shown in fig. 8 and 9 are exposed, the two nuts 742 are respectively screwed off, the end cap 71 is removed, and then the mounting tool is passed through the through hole 721 of the pressing plate 72, and the fastening member connecting the mounting base 21 and the second member 202 is screwed off, so that the second locking device 2 as a whole can be detached from the second member 202.

After the lock 10 is installed, if the door 205 needs to be locked, the door 205 is closed, the locking member 12 is inserted into the supporting seat 22, then the handle 31 is rotated, the locking member 12 slides to the tightening locking position along the tightening curved surface 232 to compress the door 205, so as to prevent cold leakage, and then the first locking mechanism 91 and the second locking mechanism 92 are used for double locking, so that the door locking process can be completed. If the door 205 needs to be opened, the first locking mechanism 91 and the second locking mechanism 92 are unlocked first, then the handle 31 is rotated in the reverse direction, so that the locking member 12 slides down from the tightening curved surface 232 to complete the reverse unlocking, and then the door 205 is rotated to open the door 205, thereby completing the door opening process.

At above-mentioned switch door in-process, owing to compel tight curved surface 232 can comparatively gently guide locking piece 12 to slide, and be equipped with rotatable axle sleeve 14 on the locking piece 12, locking piece 12 with compel to form sliding friction between the curved surface 232, consequently, only need with the rotatory handle 31 of less power, can accomplish compel tight locking and reverse unblock process, labour saving and time saving, convenient high efficiency can effectively promote user experience.
