[0040] The following detailed description and drawings of the embodiments of the present application are used to illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0041] In the description of the present application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inside", "outside", etc., indicating the orientation or positional relationship, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. "Vertical" is not strictly vertical, but is within the allowable error range. "Parallel" is not strictly parallel, but is within the allowable error range.

[0042] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present application. In the description of the present application, it should also be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense. For example, it can be a non-detachable connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0043] Motion mechanisms are widely used in various fields of production and life. In order to better meet application requirements, the motion mechanism is usually required to have the ability to lock and unlock. Such a motion mechanism with the ability to lock and unlock can also be called a locking device.

[0044] The inventor has found through research that the existing locking devices usually include two types. One is to use a V-shaped block plus a bearing, install a V-shaped part on the moving part, and install a set of cylinder push-pull bearing mechanisms on the fixed part. The push-pull direction of the cylinder is perpendicular to the moving direction of the moving part. The cylinder push-pull bearing makes the bearing and the inclined surface of the V-shaped block tangentially abut or separate, thereby realizing the locking and unlocking of the locking device; the other is to use the reversibility of the ball screw transmission, use a ball screw transmission between the fixed part and the moving part, and then cooperate with the control of the servo motor to realize the locking and unlocking of the locking device. However, both of the above-mentioned two locking devices have more or less problems such as inconvenient switching between the locked and unlocked states and large movement resistance in the unlocked state.

[0045] In view of the above problems, the inventors, after in-depth research, proposed a locking device, which includes a fixed component and a moving component, the fixed component includes a base extending in a first direction and a limiting component arranged on the base; the moving component includes a mounting seat and a rotating component arranged on the mounting seat, the mounting seat is arranged on the base and can move relative to the base in the first direction. The locking device has a first state and a second state, the rotating component can rotate around its own axis by a first angle so that the locking device is in the first state, at which time the rotating component abuts against the limiting component, and the first state is also the locked state of the locking device; the rotating component can rotate around its own axis by a second angle so that the locking device is in the second state, at which time the rotating component is disengaged from the limiting component and there is a gap between the two, the mounting seat and the base have a degree of freedom along the first direction, and the second state is also the unlocked state of the locking device. The locking device of the embodiment of the present application can freely switch between the first state and the second state by rotating the rotating part, thereby improving the convenience of switching the locking device between the locked and unlocked states. Moreover, in the unlocked state, the rotating part is disengaged from the limiting part and there is a gap between the two, and the mounting seat and the base have freedom along the first direction, thereby reducing the movement resistance of the moving component and alleviating the problem of high movement resistance of the locking device in the unlocked state.

[0046] Some embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0048] Please also read Figures 1 to 10The locking device 1 includes a fixed component 10 and a movable component 20, the fixed component 10 includes a base 11 extending along a first direction X and a limiting component 12 arranged on the base 11; the movable component 20 includes a mounting seat 21 and a rotating component 22 arranged on the mounting seat 21, the mounting seat 21 is arranged on the base 11 and can move relative to the base 11 along the first direction X; wherein, the locking device 1 includes a first state and a second state, the rotating component 22 can rotate around its own axis by a first angle so that the locking device 1 is in the first state, at which time the rotating component 22 abuts against the limiting component 12; the rotating component 22 can rotate around its own axis by a second angle so that the locking device 1 is in the second state, at which time the rotating component 22 is disengaged from the limiting component 12 and there is a gap between the two, and the mounting seat 21 and the base 11 have freedom along the first direction X.

[0049] The locking device 1 includes a fixing assembly 10, which can be understood as a collection of parts on the locking device 1 that do not have the ability to move. The fixing assembly 10 includes a base 11 extending along the first direction X, and the base 11 can be in various structural forms, such as a plate-like structure or a strip-like structure. A limiting component 12 is provided on the base 11, and the limiting component 12 and the base 11 can be connected in various ways, such as a detachable connection, such as a threaded connection, or a non-detachable connection, such as welding, or the base 11 and the limiting component 12 are an integrated structure.

[0050] The limiting component 12 can have a variety of structural forms. For example, the limiting component 12 can be a structure, such as Figure 1 In the figure, the limiting component 12 is an integrated plate-shaped structure; the limiting component 12 can also be two independent structures, for example, the limiting component 12 includes two independent columnar structures, and the two columnar structures are arranged at intervals along the first direction X.

[0051] The locking device 1 also includes a moving component 20, which can be understood as a collection of parts on the locking device 1 that have the ability to move. The moving component 20 can move relative to the fixed component 10. Specifically, in an embodiment of the present application, the moving component 20 can move along a first direction X.

[0052] The moving assembly 20 includes a mounting seat 21 . The mounting seat 21 is disposed on the base 11 and can move relative to the base 11 along a first direction X. The mounting seat 21 and the base 11 can have a variety of moving modes.

[0053] For example, in some examples, the mounting seat 21 is slidably connected to the base 11. Specifically, a slide groove may be provided on one of the mounting seat 21 and the base 11, and a slide rail may be provided on the other, and the mounting seat 21 and the base 11 are slidably connected by the cooperation of the slide groove and the slide rail.

[0054] In some other examples, the mounting seat 21 is connected to the base 11 via a third connecting member. Specifically, a roller may be provided on one of the mounting seat 21 and the base 11, and the mounting seat 21 may be moved along the base 11 by the rotation of the roller. In addition, in order to ensure the controllability of the movement of the mounting seat 21, a guide portion may be provided on the mounting seat 21 or the base 11 to guide the mounting seat 21 to move along the first direction X.

[0055] The moving assembly 20 further includes a rotating component 22 disposed on the mounting seat 21. The rotating component 22 can rotate around its own axis, and the rotating component 22 is rotatably connected to the mounting seat 21. The rotating component 22 can be a centrally symmetrical structure, for example Figures 1 to 10 In the embodiment, the rotating component 22 is a centrosymmetric cam structure; the rotating component 22 may also be a non-centrosymmetric structure, for example, the rotating component 22 may be composed of two fan-shaped structures with different arc lengths, and the two fan-shaped structures are opposite to each other along the first direction X. It should be noted that the axis of the rotating component 22 may be understood as the rotation centerline of the rotating component 22.

[0056] The locking device 1 includes a first state and a second state. The first state can be understood as the locking state of the locking device 1. In this state, the rotating component 22 abuts against the limiting component 12, so that the mounting seat 21 is restricted and relatively fixed to the base 11. The second state can be understood as the unlocking state of the locking device 1. In this state, the rotating component 22 is separated from the limiting component 12 and there is a gap between the two. The mounting seat 21 and the base 11 have a degree of freedom along the first direction X. At this time, the mounting seat 21 can move along the base 11 within a certain range of movement. This range of movement is related to the shape and size of the rotating component 22 and the range of movement of the rotating component 22 limited by the limiting component 12. When the mounting seat 21 drives the rotating component 22 to move to abut against one side of the limiting component 12, the mounting seat 21 is blocked and forced to stop moving.

[0057] The rotating part 22 can rotate around its own axis to a first angle so that the locking device 1 is in the first state. The first angle refers to the angle at which the rotating part 22 rotates during the operation of the locking device 1 from the second state to the first state; the rotating part 22 can rotate around its own axis to a second angle so that the locking device 1 is in the second state. The second angle refers to the angle at which the rotating part 22 rotates during the operation of the locking device 1 from the first state to the second state. The first angle and the second angle can be a fixed angle value or a non-fixed angle interval with a certain range of values. That is to say, the rotating part 22 can only abut against the limiting part 12 at a certain position, so that the locking device 1 is in a locked state; or the rotating part 22 can abut against the limiting part 12 within a certain position range, and the locking device 1 can be in a locked state within this range. By way of example, in the embodiment of the present application, the first angle and the second angle are both non-fixed angle intervals.

[0058] When the locking device 1 moves from the first state to the second state, the rotating part 22 first rotates so that the rotating part 22 is out of contact with the limiting part 12, and stops rotating when the rotating part 22 rotates to a certain position. At this time, the locking device 1 is in the second state, and the mounting seat 21 and the base 11 have freedom along the first direction X, so that the mounting seat 21 can move and leave its initial position; when the locking device 1 moves from the second state to the first state, the rotating part 22 rotates and gradually approaches the limiting part 12, and contacts the limiting part 12 at a certain moment, at which time the rotating part 22 continues to rotate, and the limiting part 12 gives the rotating part 22 a reaction force, thereby pulling the mounting seat 21 to move along the first direction X, and the movement of the mounting seat 21 drives the rotating part 22 to move together until the rotating part 22 abuts against the limiting part 12, at which time the movement and rotation of the rotating part 22 stop, and the locking device 1 is in the first state.

[0059] According to the locking device 1 of the embodiment of the present application, it includes a first state and a second state, the first state is the locked state of the locking device 1, and the second state is the unlocked state of the locking device 1. The locking device 1 of the embodiment of the present application can be freely switched between the first state and the second state by rotating the rotating part 22, thereby improving the convenience of switching the locking device 1 between the locked and unlocked states. Moreover, in the unlocked state, the rotating part 22 is disengaged from the limiting part 12 and there is a gap between the two, and the mounting seat 21 and the base 11 have a degree of freedom along the first direction X, thereby reducing the movement resistance of the moving component 20 and alleviating the problem of high movement resistance of the locking device 1 in the unlocked state.

[0060] Please continue reading Figures 1 to 10 In some embodiments, the rotating component 22 is symmetrical around its own axis.

[0061] The rotating component 22 is centrally symmetrical around its own axis, that is, the rotating component 22 is a centrally symmetrical structure. Therefore, when the rotating component 22 abuts against the limiting component 12, that is, when the locking device 1 is in the first state, it can ensure that the mounting seat 21 and the base 11 have a relatively determined positional relationship, thereby improving the position accuracy of the moving component 20 when it is in the locked state, thereby improving the positioning accuracy of the locking device 1.

[0062] Please continue reading Figures 1 to 10 In some embodiments, the rotating component 22 includes a first portion 221 and a second portion 222 , wherein the first portion 221 is used to abut against the limiting component 12 ; the second portion 222 is connected to the first portion 221 and protrudes relative to the first portion 221 , and the second portion 222 is rotatably connected to the mounting seat 21 .

[0063] The first part 221 is a centrally symmetrical structure, which is used to abut against the limiting component 12. The second part 222 is also a centrally symmetrical structure, which is connected to the first part 221. There are many ways of connection, which can be a non-detachable connection, such as welding, or a detachable connection, such as a threaded connection. Of course, the first part 221 and the second part 222 can also be an integrally formed structure. The second part 222 is rotatably connected to the mounting seat 21, and the second part 222 can rotate relative to the mounting seat 21 to drive the first part 221 to rotate.

[0064] By setting the rotating component 22 to include a first part 221 and a second part 222, and making the second part 222 rotatably connected to the mounting seat 21, the connection between the rotating component 22 and the mounting seat 21 can be facilitated, and the probability of interference between the first part 221 and the mounting seat 21 can be reduced, thereby improving the movement stability of the rotating component 22.

[0065] Furthermore, at least a portion of the first portion 221 is an arc-shaped structure.

[0066] At least part of the first portion 221 is an arc-shaped structure, that is, part of the first portion 221 may be an arc-shaped structure, or the first portion 221 may be an arc-shaped structure as a whole. For example, in the embodiment of the present application, the first portion 221 is an arc-shaped structure as a whole.

[0067] Setting at least a portion of the first portion 221 as an arc-shaped structure can reduce the contact area between the first portion 221 and the limiting component 12, thereby reducing the friction between the first portion 221 and the limiting component 12, improving the movement stability of the rotating component 22, and alleviating friction damage between the first portion 221 and the limiting component 12.

[0068] See also Figures 1 to 10In some embodiments, the first portion 221 includes two sub-portions 221a that are centrally symmetrical to each other, and the sub-portion 221a includes a first surface 221b for abutting against the limiting component 12, and the first surface 221b is an arc surface.

[0069] When the locking device 1 is in the first state, the first surface 221b abuts against the limiting component 12. The first surface 221b is an arcuate surface, which can be understood as being formed by smoothly connecting a plurality of arcuate surfaces with different radii in the present application.

[0070] Therefore, the first surface 221b is set as an arc surface, and when the locking device 1 is operated from the first state to the second state, there is a small friction force between the first surface 221b as an arc surface and the limiting component 12, so that the movement resistance of the rotating component 22 when it is operated to the second state can be reduced. In addition, when the locking device 1 is operated from the second state to the first state, in addition to reducing the friction force between the first surface 221b and the limiting component 12, the mounting seat 21 can also be pulled by the rotating component 22 to move more smoothly, thereby improving the movement stability of the moving component 20.

[0071] Furthermore, the sub-portion 221a further includes a second surface 221c intersecting the first surface 221b, and the second surface 221c is recessed in a direction approaching the first surface 221b.

[0072] The second surface 221c may also be configured as an arc-shaped surface. For example, in the embodiment of the present application, the second surface 221c may be understood as being formed by smoothly connecting a plurality of arc-shaped surfaces with different radii.

[0073] The second surface 221c is recessed in a direction close to the first surface 221b, that is, the second surface 221c is closer to the axis of the rotating part 22 than the first surface 221b, so that when the locking device 1 moves from the first state to the second state, the rotating part 22 can be out of contact with the limiting part 12.

[0074] Please continue reading Figures 1 to 10 In some embodiments, the locking device 1 further includes a driving component 30, which is disposed on the mounting seat 21, and the driving component 30 is connected to the second portion 222 and is used to drive the rotating component 22 to rotate around its own axis.

[0075] The driving component 30 may have various structures. For example, it may be a motor capable of rotating motion, such as a servo motor, a stepper motor or an ordinary motor.

[0076] The driving component 30 may include a driving body 31 and a driving shaft 32. The driving body 31 drives the driving shaft 32 to rotate. The driving body 31 is disposed on a side of the mounting seat 21 away from the first portion 221. The driving body 31 and the mounting seat 21 may be connected in a variety of ways, such as bolt connection, clamping, etc.

[0077] The driving shaft 32 is located in the mounting seat 21 and is rotatably connected to the driving body 31. The driving shaft 32 is connected to the second portion 222 and drives the second portion 222 to rotate. The driving shaft 32 and the second portion 222 can have a variety of connection methods.

[0078] In some examples, the drive shaft 32 is connected to the second portion 222 via a transfer member. For example, a coupling or a flange may be provided between the drive shaft 32 and the second portion 222 .

[0079] In other examples, the drive shaft 32 is embedded in the second part 222 and fixedly connected to the second part 222. For example, in the embodiment of the present application, the second part 222 has a through hole, and the drive shaft 32 is inserted into the through hole of the second part 222 and fixedly connected to the second part 222. The advantage of this connection method is that the axial size of the drive shaft 32 and the second part 222 along the rotating component 22 can be reduced, thereby reducing the space occupancy rate of the moving assembly 20, and further reducing the volume of the locking device 1.

[0080] Please continue reading Figures 1 to 10 In some embodiments, the locking device 1 further includes a reinforcing member 40 embedded in the mounting seat 21 , the reinforcing member 40 is sleeved outside the second portion 222 and is used to fix the second portion 222 along the radial direction of the second portion 222 .

[0081] The reinforcing member 40 may be a bearing, the second portion 222 is embedded in the inner ring of the bearing and fixedly connected to the inner ring, the outer ring of the bearing is fixedly connected to the mounting seat 21, and the relative rotation of the inner ring and the outer ring enables the relative rotation of the rotating component 22 and the mounting seat 21. The reinforcing member 40 may be provided as one or more. For example, in the embodiment of the present application, the reinforcing member 40 is provided as two.

[0082] By providing the reinforcing member 40 , the connection strength between the second portion 222 and the mounting seat 21 can be improved, thereby enhancing the structural stability of the moving component 20 and improving the movement stability and impact resistance of the rotating component 22 .

[0083] Furthermore, a fixing member 50 is also disposed on the second portion 222 , and the fixing member 50 is used to fix the reinforcing member 40 along the axial direction of the second portion 222 .

[0084] The fixing member 50 may be a retaining ring, a retaining ring, etc. The fixing member 50 may enhance the axial fixing effect of the reinforcing member 40, enhance the structural stability among the reinforcing member 40, the second portion 222 and the mounting seat 21, and thus enhance the structural stability of the locking device 1. The fixing member 50 may have different sizes according to different installation positions, and the fixing member 50 may be provided as one or more. For example, in the embodiment of the present application, two fixing members 50 are provided.

[0085] Please continue reading Figures 1 to 10 In some embodiments, the moving component 20 further includes two control switches 23 disposed on the mounting base 21, both of which are control-connected to the driving component 30, and a sensing component 24 is disposed on the first portion 221, and the sensing component 24 is used to instantaneously trigger the control switch 23 when approaching the control switch 23 to stop the driving component 30 from running; in the first state, the sensing component 24 is located within the triggering range of one of the control switches 23; in the second state, the sensing component 24 is located within the triggering range of the other control switch 23.

[0086] The control switch 23 is connected to the driving component 30 by a control method, and the connection method can be a wired connection or a wireless connection, which is not limited in this application. The sensing component 24 is used to instantaneously trigger the control switch 23 when it is close to the control switch 23 to stop the driving component 30. That is to say, there is an intermittent trigger response between the sensing component 24 and the control switch 23. Specifically, when the sensing component 24 enters the trigger range of the control switch 23, it will trigger the control switch 23 to stop the driving component 30. After the control switch 23 is triggered once, it will be temporarily in a closed state. At this time, the driving component 30 is started again to drive the first part 221 to rotate. After that, even if the sensing component 24 has not left the trigger range of the original control switch 23, the original control switch 23 will not continue to be triggered until the first part 221 rotates to enter the trigger range of the next control switch 23, at which time the control switch 23 will be triggered to stop the driving component 30.

[0087] In conjunction with the attached drawings, Figure 6 and Figure 7 The figures show two extreme positions of the first portion 221 of the locking device 1 in the first state, that is, two extreme positions of the sensing component 24 in the triggering range of the control switch 23. Figure 6 to Figure 7 When the locking device 1 is in any position between the first and second positions, the control switch 23 may be triggered to stop the driving component 30, thereby placing the locking device 1 in the first state. Fig.10 The angle a corresponding to the first portion 221 is the angle between the first portion 221 and Figure 6 Run to the position shown Figure 7The angle rotated when the position is shown is within the range of angle a. The first part 221 is an arc structure, and the radius of the arc structure is R1. The advantage of such a setting is that when the locking device 1 enters the locked state from the unlocked state, no matter where the sensing component 24 triggers the control switch 23 within the range of angle a, it can ensure that the moving component 20 has stopped moving at this time, and the accuracy of the stopping position of the moving component 20 will not be affected by the timeliness of the trigger, thereby improving the positioning accuracy of the locking device 1.

[0088] Figure 8 and Fig. 9 The two limit positions of the first portion 221 of the locking device 1 in the second state are shown, that is, the two limit positions of the sensing component 24 in the triggering range of the control switch 23. Figures 8 to 9 When the locking device 1 is in any position between the first and second positions, the control switch 23 may be triggered to stop the driving component 30, thereby placing the locking device 1 in the second state. Fig.10 The angle c corresponding to the first portion 221 is the angle between the first portion 221 and Figure 8 Run to the position shown Fig. 9 The angle of rotation when in the position shown is within the range of angle c. The first part 221 is an arc structure, and the radius of the arc structure is R2. The advantage of such a setting is that when the locking device 1 enters the unlocking state from the locked state, no matter where the sensing component 24 triggers the control switch 23 within the range of angle c, the maximum unidirectional moving distance of the moving component 20 can be ensured to be the same, and this maximum unidirectional moving distance is R1-R2, thereby improving the positioning accuracy of the locking device 1.

[0089] It should be noted that Fig.10 The angle b corresponding to the first portion 221 is the angle between the first portion 221 and Figure 7 Run to the position shown Figure 8 The position shown is the angle through which it is rotated.

[0090] Furthermore, two sensing components 24 are provided, and the two sensing components 24 are symmetrical around the axis of the rotating component 22 .

[0091] Therefore, by setting two centrally symmetrical sensing components 24, the rotation period of the rotating component 22 can be shortened to 180°. Within one rotation period, the locking device 1 can switch from the first state to the second state and then to the first state, thereby reducing the rotation stroke of the rotating component 22 and improving the working efficiency of the locking device 1.

[0092] Combined with Fig.10 From the perspective of the angle d corresponding to the first portion 221, the angle d corresponding to the first portion 221 is the angle d corresponding to the first portion 221 from Fig. 9 Run again to the position shown Figure 6 The position shown is the angle through which the rotation is performed, and the angle a+b+c+d is a rotation period of the rotating component 22 of 180°.

[0093] Please continue reading Figures 1 to 10 In some embodiments, the limiting component 12 includes a supporting portion 121 and two limiting portions 122. The supporting portion 121 is disposed on the base 11 and is located on one side of the moving component 20. The two limiting portions 122 are disposed on the supporting portion 121 and protrude relative to the supporting portion 121 toward a direction close to the moving component 20. The two limiting portions 122 are opposite to each other and spaced apart along the first direction X. In the first state, the rotating component 22 is located between the two limiting portions 122 and abuts against the two limiting portions 122.

[0094] The support portion 121 is disposed on the base 11. The support portion 121 and the base 11 may be connected in a variety of ways, such as threaded connection, welding, etc., or the support portion 121 and the base 11 may be an integrated structure. The support portion 121 itself may have a variety of structural forms, such as a plate-like structure, and a through hole may be provided on the support portion 121 to reduce its own weight, thereby reducing the weight of the locking device 1.

[0095] The two limiting parts 122 are arranged on the supporting part 121. The limiting parts 122 and the supporting part 121 can have various connection relationships, and the two can be fixedly connected or movably connected. The two limiting parts 122 protrude relative to the supporting part 121 toward the direction close to the moving assembly 20, so as to reduce the possibility of interference between the rotating part 22 and the supporting part 121, thereby improving the movement stability of the rotating part 22.

[0096] In some embodiments, the side surface of the limiting portion 122 facing the rotating component 22 is an arc-shaped surface. Therefore, when the rotating component 22 abuts against the limiting portion 122, the contact area between the rotating component 22 and the limiting portion 122 can be reduced, thereby reducing the friction between the rotating component 22 and the limiting portion 122, thereby reducing the movement resistance of the rotating component 22 and improving its movement stability.

[0097] Furthermore, the limiting portion 122 is rotatably connected to the supporting portion 121 , and the limiting portion 122 is configured to rotate under force.

[0098] Thus, when the rotating component 22 abuts against the limiting portion 122 and applies a force to the limiting portion 122, the limiting portion 122 itself can rotate under the force, thereby reducing the friction between the rotating component 22 and the limiting portion 122 and improving the movement stability of the rotating component 22. The limiting portion 122 can have a variety of structural forms. For example, in the present application, the limiting portion 122 can be a bearing.

[0099] The present application also proposes a carrying device, which includes a locking device 1 according to any one of the above embodiments and a device body, wherein the locking device 1 is arranged on the device body.

[0100] The carrying equipment can be in various structural forms. For example, it can be a fixed device without mobility, or it can be a car, AGV, etc. with mobility.

[0101] The carrier device is provided with a locking device 1, which enables the carrier device to have a certain degree of freedom in a certain direction and has the ability to lock and unlock, thereby expanding the application scenarios of the carrier device.

[0102] As a specific embodiment of the present application, the locking device 1 includes a fixed component 10 and a moving component 20, the fixed component 10 includes a base 11 extending along a first direction X and a limiting component 12 arranged on the base 11; the moving component 20 includes a mounting seat 21 and a rotating component 22 arranged on the mounting seat 21, the mounting seat 21 is arranged on the base 11 and can move relative to the base 11 along the first direction X, the rotating component 22 includes a first part 221 and a second part 222, the first part 221 is used to abut against the limiting component 12, and at least part of it is an arc structure, and the second part 222 is connected The second part 222 is rotatably connected to the mounting seat 21 and protrudes relative to the first part 221; wherein the locking device 1 includes a first state and a second state, the rotating part 22 can rotate around its own axis by a first angle to put the locking device 1 in the first state, at which time the first part 221 abuts against the limiting part 12; the rotating part 22 can rotate around its own axis by a second angle to put the locking device 1 in the second state, at which time the first part 221 is disengaged from the limiting part 12 and there is a gap between the two, and the mounting seat 21 and the base 11 have freedom along the first direction X.

[0103] According to the locking device 1 of the embodiment of the present application, it includes a first state and a second state, the first state is the locked state of the locking device 1, and the second state is the unlocked state of the locking device 1. The locking device 1 of the embodiment of the present application can be freely switched between the first state and the second state by rotating the rotating part 22, thereby improving the convenience of switching the locking device 1 between the locked and unlocked states. Moreover, in the unlocked state, the rotating part 22 is disengaged from the limiting part 12 and there is a gap between the two, and the mounting seat 21 and the base 11 have a degree of freedom along the first direction X, thereby reducing the movement resistance of the moving component 20 and alleviating the problem of high movement resistance of the locking device 1 in the unlocked state.

[0104] Furthermore, by providing the rotating component 22 with the first portion 221 and the second portion 222, and making the second portion 222 rotatably connected to the mounting seat 21, the connection between the rotating component 22 and the mounting seat 21 can be facilitated, and the probability of interference between the first portion 221 and the mounting seat 21 can be reduced, thereby improving the motion stability of the rotating component 22. Moreover, at least part of the first portion 221 is an arc-shaped structure, which can reduce the contact area between the first portion 221 and the limiting component 12, thereby reducing the friction between the first portion 221 and the limiting component 12, improving the motion stability of the rotating component 22, and alleviating the friction damage between the first portion 221 and the limiting component 12.
