[0007] In some embodiments, the first locking mechanism further includes a ball joint portion disposed between the first fixing portion and the first locking portion, and the first locking mechanism is ball-jointedly connected to the first fixing portion via the ball joint portion.

[0008] In the scheme of the embodiment of the present application, the first locking part and the first fixing part are connected by a ball joint through a ball joint to increase the degree of freedom of the first locking part, so that the first locking mechanism can absorb errors in more directions generated during the installation and operation of the locking device, thereby improving the reliability of the locking device.

[0009] In some embodiments, the first locking mechanism further includes an elastic return member, one end of the elastic return member is connected to the first fixing portion, and the other end of the elastic return member is connected to the first locking portion.

[0041] In the prior art, the locking structure and the matching structure of the locking device require high positioning accuracy during installation and subsequent work, and the locking device is difficult to install and lacks reliability.

[0042] In the related art, during the installation of the locking device, if there is a deviation between the locking structure and the mating structure, then during the subsequent operation of the locking device, the locking mechanism and the mating structure may be unable to connect and lock, or the locking force may be insufficient; or during the operation of the locking device, the internal components of the locking device may vibrate or deform under the action of external force, resulting in a deviation between the locking mechanism and the mating structure, and the locking mechanism and the mating structure may be unable to connect and lock, or the locking force may be insufficient, which has an adverse effect on the reliability of the locking device.

[0043] Based on the above problems, an embodiment of the present application provides a locking device, which includes a first locking mechanism and a second locking mechanism, the first locking mechanism includes a first fixing portion and a first locking portion connected to each other, the first locking mechanism is fixed to the first installation area through the first fixing portion, the second locking mechanism includes a second fixing portion and a second locking portion connected to each other, the second locking mechanism is fixed to the second installation area through the second fixing portion, when the locking device is in a locked state, the first locking portion and the second locking portion are connected to each other, when the locking device is in an unlocked state, the first locking portion can move relative to the second locking portion, wherein the first locking portion is rotatable relative to the first fixing portion around a first direction, and the first direction is parallel to a side surface of the first fixing portion facing the first locking portion, thereby absorbing the alignment error between the first locking mechanism and the second locking mechanism during installation and subsequent work by moving the first locking portion, so as to reduce the installation difficulty of the locking device and improve the reliability of the locking device.

[0044] See also Figure 1 , Figure 1 It is a schematic diagram of the structure of a locking device provided in one embodiment of the present application.

[0045] like Figure 1As shown, the present application provides a locking device 1, which includes a first locking mechanism 2 and a second locking mechanism 3. The first locking mechanism 2 includes a first fixing portion 21 and a first locking portion 22 connected to each other, and the first fixing portion 21 is used to connect to the first installation area; the second locking mechanism 3 includes a second fixing portion 31 and a second locking portion 32 connected to each other, and the second fixing portion 31 is used to connect to the second installation area. The locking device 1 is configured to include a locked state and an unlocked state. In the locked state, the first locking portion 22 and the second locking portion 32 are connected to each other, and in the unlocked state, the first locking portion 22 can move relative to the second locking portion 32, wherein the first locking portion 22 is rotatable relative to the first fixing portion 21 around a first direction X, and the first direction X is parallel to a side surface of the first fixing portion 21 facing the first locking portion 22.

[0046] In the solution of the embodiment of the present application, the locking device 1 includes a first locking mechanism 2 and a second locking mechanism 3, the first locking mechanism 2 includes a first fixing portion 21 and a first locking portion 22 connected to each other, the first locking mechanism 2 is fixed to the first installation area through the first fixing portion 21, the second locking mechanism 3 includes a second fixing portion 31 and a second locking portion 32 connected to each other, the second locking mechanism 3 is fixed to the second installation area through the second fixing portion 31, when the locking device 1 is in a locked state, the first locking portion 22 and the second locking portion 32 are connected to each other, when the locking device 1 is in an unlocked state, the first locking portion 22 can move relative to the second locking portion 32, wherein the first locking portion 22 is rotatable relative to the first fixing portion 21 around a first direction X, and the first direction X is parallel to a side surface of the first fixing portion 21 facing the first locking portion 22, thereby the alignment error between the first locking mechanism 2 and the second locking mechanism 3 generated during installation and subsequent work can be absorbed by the movement of the first locking portion 22, so as to reduce the installation difficulty of the locking device 1 and improve the reliability of the locking device 1.

[0047] The first locking mechanism 2 is arranged in the first installation area through the first fixing portion 21, and the second locking mechanism 3 is arranged in the second installation area through the second fixing portion 31. Exemplarily, the locking device 1 is installed on a cabinet door, a container door, or a laboratory safety door, etc., the first installation area is located on the door panel, the second installation area is located on the door frame, the door panel and the door frame are connected by a hinge, the locking device 1 is in a locked state, the first locking mechanism 2 and the second locking mechanism 3 are connected to each other, thereby the door panel and the door frame remain relatively fixed; the locking device 1 is in an unlocked state, the first locking mechanism 2 and the second locking mechanism 3 are separated, and the door panel and the door frame can move relative to each other.

[0048] The first locking mechanism 2 is connected to the first installation area via the first fixing portion 21 , and the first fixing portion 21 and the first installation area may be connected by rivets, screws, or welding, etc. The second fixing portion 31 is similar.

[0049] When the locking device 1 is in a locked state, the first locking portion 22 and the second locking portion 32 are connected to each other. The connection between the first locking portion 22 and the second locking portion 32 may be electromagnetic connection, clamping connection, threaded connection, or the like.

[0050] Optionally, the locking device 1 may include multiple first locking mechanisms 2 and the same number of second locking mechanisms 3, thereby increasing the locking force of the locking device 1 and maintaining the overall locking state when some of the first locking mechanisms 2 or the second locking mechanisms 3 fail, thereby improving the reliability of the locking device 1.

[0051] For example, in the related art, the first locking portion 22 and the second locking portion 32 have high positioning accuracy requirements. At least the central axes of the first locking portion 22 and the second locking portion 32 must be kept parallel to each other in the unlocked state and the locked state. Only in this way can the reliability of the first locking portion 22 and the second locking portion 32 in the locked state be guaranteed.

[0052] In the embodiment of the present application, the first locking portion 22 is rotatable relative to the first fixing portion 21 around the first direction X. Therefore, even in the unlocked state, there is a deviation between the first locking portion 22 and the second locking portion 32 during installation. This deviation can be overcome by rotating the first locking portion 22 to maintain the first locking portion 22 and the second locking portion 32 reliably connected in the locked state, and the central axes of the first locking portion 22 and the second locking portion 32 are parallel.

[0053] The first direction X is parallel to a side surface of the first fixing portion 21 facing the first locking portion 22, and a straight line extending in the first direction X is parallel to a side surface of the first fixing portion 21 facing the first locking portion 22. Exemplarily, the first direction X is a length direction or a width direction of the first fixing portion 21.

[0054] Optionally, the first locking portion 22 is rotatably disposed relative to the first fixing portion 21 around a direction intersecting with a side surface of the first fixing portion 21 facing the first locking portion 22 .

[0055] Optionally, one of the first fixing portion 21 or the first locking portion 22 is provided with an axial hole extending along the first direction X, and the other of the first fixing portion 21 or the first locking portion 22 is provided with a rotating shaft extending along the first direction X and extending into the axial hole, so that the first locking portion 22 is rotatable relative to the first fixing portion 21.

[0056] Or, in other embodiments, Figure 1 As shown, the first locking mechanism 2 further includes a ball joint portion 23 disposed between the first fixing portion 21 and the first locking portion 22 , and the first locking mechanism 2 is connected to the first fixing portion 21 by a ball joint via the ball joint portion 23 .

[0057] In these embodiments, the first locking portion 22 and the first fixing portion 21 are connected by a ball joint via a ball joint portion 23 to increase the degree of freedom of the first locking portion 22 so that the first locking mechanism 2 can absorb errors in more directions generated during the installation and operation of the locking device 1 to improve the reliability of the locking device 1.

[0058] The first fixing part 21 applies a ball joint constraint to the first locking mechanism 2 through the ball joint part 23, so that the first locking part 22 can rotate relative to the first fixing part 21 in multiple directions without separating from the first fixing part 21, thereby absorbing the alignment errors in multiple directions generated during the installation and operation of the locking device 1. In addition, the ball joint part 23 can also provide a rigid connection between the first locking mechanism 2 and the second locking mechanism 3 in the locked state when the first locking part 22 and the first fixing part 21 are relatively rotatable, so as to improve the overall stability of the locking device 1.

[0059] The ball joint connection usually includes a ball head 2321 and a ball shell, that is, a hemispherical groove 2311 is opened on the surface of one of the first fixing part 21 and the first locking part 22, and the other is connected to the ball head 2321. The ball head 2321 is accommodated in the hemispherical groove 2311 to realize the ball joint connection between the first fixing part 21 and the first locking part 22.

[0060] See also Figure 2 , Figure 2 yes Figure 1 Partial structural cross-sectional view at AA in the middle.

[0061] In some embodiments, Figure 1 and Figure 2 As shown, the ball joint portion 23 includes a first segment 231 and a second segment 232, one end of the first segment 231 is connected to one of the first fixing portion 21 or the first locking portion 22, and the other end of the first segment 231 is provided with a hemispherical groove 2311, one end of the second segment 232 is connected to the other of the first fixing portion 21 or the first locking portion 22, and the other end of the second segment 232 is provided with a ball head 2321, the ball head 2321 is accommodated in the hemispherical groove 2311, and the ball head 2321 is rotatable relative to the hemispherical groove 2311.

[0062] In these embodiments, the ball joint portion 23 includes a first segment 231 and a second segment 232. The ball head 2321 of the second segment 232 can be rotatably accommodated in the hemispherical groove 2311 of the first segment 231 to realize a ball joint connection between the first fixing portion 21 and the first locking portion 22. The hemispherical groove 2311 arranged on the first segment 231 reduces the damage to the structural strength of the first fixing portion 21 or the first locking portion 22, and the first segment 231 extending from the first fixing portion 21 or the first locking portion 22 can increase the rotatable angle between the first fixing portion 21 and the first locking portion 22, so that the first locking portion 22 can absorb a larger angle error of the locking device 1.

[0063] The first segment 231 extends from the surface of the first fixing portion 21 facing the first locking portion 22, or the first segment 231 extends from the surface of the first locking portion 22 facing the first fixing portion 21, so that the extended first segment 231 can provide a larger rotation space for the relative rotation of the first fixing portion 21 and the first locking portion 22, and the first locking portion 22 can also rotate a larger angle relative to the first fixing portion 21. Similarly, the extended second segment 232 also has the effect of providing a larger rotation space.

[0064] Exemplarily, the first segment 231 is connected to the first fixing portion 21 , and the second segment 232 is connected to the first locking portion 22 .

[0065] Optionally, the first segment 231 and one of the first fixing portion 21 or the first locking portion 22 are integrally formed to enhance the connection strength between the first segment 231 and the first fixing portion 21 or the first locking portion 22; the second segment 232 and one of the first fixing portion 21 or the first locking portion 22 are integrally formed to enhance the connection strength between the second segment 232 and the first fixing portion 21 or the first locking portion 22.

[0066] Optionally, the first segment 231 and one of the first fixing portion 21 or the first locking portion 22 are detachably connected, and the second segment 232 and one of the first fixing portion 21 or the first locking portion 22 are detachably connected, so as to facilitate the replacement and maintenance of the ball joint 23. Exemplarily, the ball joint 23 is a spherical bearing, and the first segment 231 and the second segment 232 are threadedly connected to the first fixing portion 21 and the first locking portion 22, respectively.

[0067] See also Figure 3 , Figure 3 It is a schematic structural diagram of a locking device provided in another embodiment of the present application.

[0068] In some embodiments, Figure 3 As shown, the first locking mechanism 2 further includes an elastic reset member 24 , one end of the elastic reset member 24 is connected to the first fixing portion 21 , and the other end thereof is connected to the first locking portion 22 .

[0069] In these embodiments, the first locking mechanism 2 also includes an elastic reset member 24 having one end connected to the first fixed portion 21 and the other end connected to the first locking portion 22. The elastic reset member 24 can reset the first locking portion 22 in the unlocked state to reduce the problem of excessive displacement of the first locking portion 22 under the action of external force, which makes it impossible to connect the first locking portion 22 and the second locking portion 32, thereby improving the reliability of the locking device 1.

[0070] Exemplarily, the elastic return member 24 is a spring, a spring sheet, a rubber strip, or the like.

[0071] The elastic return member 24 is connected to the first fixing portion 21 and the first locking portion 22. When the locking device 1 is changed from an unlocked state to a locked state, the first locking portion 22 rotates relative to the first fixing portion 21 to accommodate the second fixing portion 31. During the rotation of the first locking portion 22, the elastic return member 24 is deformed by force. In the locked state of the locking device 1, the second locking portion 32 continuously applies a force to the elastic return member 24 through the first locking portion 22 to maintain the deformation of the elastic return member 24. When the locking device 1 is changed from a locked state to an unlocked state, the first locking portion 22 and the second locking portion 32 are separated, and the second locking portion 32 no longer applies a force to the first locking portion 22. The force acting on the elastic return member 24 disappears, the deformation of the elastic return member 24 disappears, and the elastic return member 24 drives the first locking portion 22 to reset.

[0072] In addition, the elastic return member 24 can automatically assist the first locking part 22 to reset after the first locking part 22 is offset by external force, thereby shortening the adjustment time of the first locking part 22 in the locked state and making the locking process smoother. The above-mentioned external force may come from the weight of the first locking part 22 or from the touch of an external object.

[0073] Optionally, the first locking mechanism 2 may include a plurality of elastic return members 24 , so that the first locking mechanism 2 can still be used after some of the elastic return members 24 are damaged, thereby improving the fault tolerance of the first locking mechanism 2 .

[0074] Optionally, the elastic reset member 24 and the first fixing portion 21 may be connected in a threaded connection, a clamping connection, a riveting connection, a welding connection, etc. The connection between the elastic reset member 24 and the first locking portion 22 is similar.

[0075] In some embodiments, Figure 3 As shown, the elastic reset member 24 is disposed around the ball joint 23 .

[0076] In these embodiments, the elastic reset member 24 is disposed around the ball joint 23 so that the elastic reset member 24 is evenly stressed, thereby increasing the service life of the elastic reset member 24 .

[0077] Exemplarily, the elastic reset member 24 is a spring, and the ball joint portion 23 is inserted into the spring.

[0078] The first segment 231 and the second segment 232 are disposed in the elastic return member 24 .

[0079] Optionally, in the unlocked state, central axes of the first fixed portion 21, the first locking portion 22, the elastic return member 24 and the ball joint portion 23 coincide, so that during the use of the locking device 1, the elastic return member 24 is subjected to uniform force, which reduces the risk of irreversible deformation of the elastic return member 24 due to long-term unidirectional force and increases the service life of the elastic return member 24.

[0080] In some embodiments, Figure 3 As shown, the first locking portion 22 and the second locking portion 32 are both magnetic parts. In the locked state, the first locking portion 22 and the second locking portion 32 are magnetically connected.

[0081] In these embodiments, the first locking portion 22 and the second locking portion 32 are both magnetic parts. In the locked state, the first locking portion 22 and the second locking portion 32 are magnetically connected. The magnetically connected first locking portion 22 and the second locking portion 32 reduce the risk of the first locking portion 22 and the second locking portion 32 being stuck or the locking force being insufficient due to the deformation of the internal structural parts during the operation of the locking device 1, thereby improving the reliability of the locking device 1.

[0082] One of the first locking part 22 and the second locking part 32 is a permanent magnet or made of ferromagnetic material, and the other of the first locking part 22 and the second locking part 32 is an electromagnet. When the locking device 1 is in a locked state, the electromagnet is energized to generate material to attract the other; when the locking device 1 is in an unlocked state, the electromagnet is turned off and the electromagnetic property disappears, and the first locking part 22 and the second locking part 32 are separated.

[0083] Alternatively, both the first locking portion 22 and the second locking portion 32 are permanent magnets, or one of the first locking portion 22 and the second locking portion 32 is a permanent magnet and the other is a ferromagnetic material. In the locked state of the locking device 1, the first locking portion 22 and the second locking portion 32 are magnetically connected, and a driving member is further provided on the first locking portion 22 or the second locking portion 32. In the unlocked state of the locking device 1, the driving member drives a magnetic conductive sheet to enter between the first locking portion 22 and the second locking portion 32, and the magnetic attraction between the first locking portion 22 and the second locking portion 32 decreases, and the first locking portion 22 and the second locking portion 32 are separated.

[0084] In some embodiments, Figure 3 As shown, the second locking portion 32 is an electromagnet.

[0085] In these embodiments, the second locking portion 32 is set as an electromagnet. When the first locking portion 22 and the second locking portion 32 are magnetically connected, the risk of interference between the electric wires of the electromagnet and the ball joint portion 23 of the first locking mechanism 2 can be reduced, thereby reducing the difficulty of preparing the locking device 1 and improving the reliability of the locking device 1.

The sensor member 42 is used to obtain information of the label member 41 to control the locking device 1 to switch between an unlocked state and a locked state.

The sensor member 42 is used to obtain information from the label member 41 to control the locking device 1 to switch between an unlocked state and a locked state. As a result, the first locking mechanism 2 and the second locking mechanism 3 belonging to one locking device 1 correspond one to one, thereby reducing the risk of misoperation of the locking device 1 and improving the reliability of the locking device 1.

[0089] The label component 41 is arranged on one of the first locking mechanism 2 or the second locking mechanism 3, and the label machine marks the information of the first locking mechanism 2 or the second locking mechanism 3. The sensor component 42 is arranged on the other of the first locking mechanism 2 or the second locking mechanism 3, and the sensor component 42 is used to read the information of the label component 41. Only after the sensor component 42 reads the information of the specific label component 41, the locking device 1 can be unlocked or locked.

[0090] Exemplarily, the passive tag component 41 is disposed on the first locking mechanism 2, and the induction component 42 is disposed on the second locking mechanism 3, and the induction component 42 can share the power supply for driving the electromagnet.
