Description

[0001] Self-locking mechanism, liquid-cooled switch, and equipment cabinet. This disclosure claims priority to Chinese patent application number 202311828347.0, filed with the Patent Office of China on December 27, 2023, entitled "Self-locking mechanism, liquid-cooled switch, and equipment cabinet," the entire contents of which are incorporated herein by reference. Technical Field: This disclosure relates to the field of server technology, and more particularly to a self-locking mechanism, a liquid-cooled switch, and an equipment cabinet. Background: With the rapid development of communications and network technologies, the scale and power density of data centers are continuously increasing. Data centers include data processing equipment, networking equipment, and telecommunications equipment. These devices generate a large amount of heat during operation, increasing their temperatures and thus affecting the power usage effectiveness (PUE) of the data center. In related art, to reduce the PUE of data centers, liquid cooling systems are typically used to cool data center equipment. However, the installation between the liquid-cooled switch and the equipment cabinet in these liquid cooling systems is relatively cumbersome, reducing the installation efficiency of the liquid-cooled switch. SUMMARY OF THE INVENTION Embodiments of the present disclosure provide a self-locking mechanism, a liquid-cooled switch, and an equipment cabinet. According to a first aspect of the embodiments of the present disclosure, a self-locking mechanism is provided, comprising: a support member; a locking member disposed on the support member and including a first locking portion movably connected to the support member, wherein the first locking portion has a first state and a second state. When the first locking portion is in the first state, the self-locking mechanism is in an unlocked state; when the first locking portion is in the second state, the self-locking mechanism is in a locked state; a driving member movably disposed on the support member and connected to the first locking portion, the driving member driving the first locking portion to move the first locking portion so as to transition the first locking portion between the first state and the second state. The self-locking mechanism provided in the embodiments of the present disclosure includes a locking member and a driving member. The locking member includes a first locking portion, and the first locking portion has a first state and a second state. The driving member is connected to the first locking portion to transition the first locking portion between the first state and the second state. When the driver moves the first locking portion to the second state, the self-locking mechanism and the support component can be quickly locked, for example, the self-locking mechanism and the equipment cabinet can be quickly locked. When the driver moves the first locking portion to the first state, the self-locking mechanism and the support component can be quickly unlocked, thereby facilitating the rapid separation of the self-locking mechanism from the support component, for example, the rapid unlocking and separation of the self-locking mechanism from the equipment cabinet.Compared to related technologies, this eliminates the need for additional installation tools, saving installation time or disassembly time between the self-locking mechanism and the support component, reducing installation costs and improving installation efficiency. In one possible implementation, the movable direction of the driving member intersects with the movable direction of the first locking portion. In one possible implementation, one end of the locking member is rotatably connected to the support member, and the locking member further includes a locking groove having interconnected locking and unlocking zones. The driving member includes a first driving portion movably connected to the locking groove. When the locking member moves between the locking and unlocking zones, the locking member rotates relative to the support member. When the first driving portion is in the unlocking zone, the first locking portion is in a first state. When the first driving portion is in the locking zone, the first locking portion is in a second state. In one possible implementation, the driving member further includes a second driving portion, one end of which is connected to the support member, and the other end of which is connected to the first driving portion. The second driving portion drives the first driving portion to move from the unlocking zone to the locking zone, thereby placing the first locking portion in the second state. In one possible implementation, the support member is provided with a mounting support, the driving member defines a mounting cavity, and at least a portion of the mounting support is located within the mounting cavity. An inner wall of the mounting cavity opposite the mounting support is connected to the mounting support via an elastic member, wherein the elastic member constitutes the second driving portion. In one possible implementation, the self-locking mechanism further includes an elastic return member, comprising a first connecting end, a second connecting end, and a spiral segment connecting the first and second connecting ends. The first and second connecting ends are respectively connected to the support member, and the spiral segment is located above and abuts the locking member. When the second driving unit drives the first driving unit from the unlocking zone to the locking zone, the first driving unit releases the restraint on the locking member, and the elastic return member drives the first locking member to rotate about the locking member's rotation axis, placing the first locking member in the second state. In one possible implementation, the locking groove includes a first locking groove and a second locking groove that are interconnected, the first locking groove having a depth less than that of the second locking groove. The first locking groove constitutes the unlocking zone, and the second locking groove constitutes the locking zone. In one possible implementation, the locking member further includes a locking plate and a rotating shaft. The locking plate is rotatably connected to the support member via the rotating shaft, and the locking groove and the first locking member are spaced apart on the locking plate.In one possible implementation, the locking plate includes a notch extending through the locking plate along its thickness, with its open end facing the driver. Two first locking portions are provided, one located on either side of the notch. The first locking portion includes a latching protrusion, and the longitudinal cross-section of the first locking portion is triangular, or alternatively, trapezoidal, with the longitudinal cross-section perpendicular to the surface of the locking plate. In one possible implementation, the driver includes a driving plate and two driving arms connected to the driving plate. The two driving arms are located on either side of the locking plate, with each end of the driving arm facing away from the driving plate bent toward the locking plate to form the first driving portion. In one possible implementation, the driving plate is provided with a first gripping hole, and the support member is provided with a second gripping hole. The first gripping hole and the second gripping hole are disposed opposite and interconnected, with a portion of the driving plate exposed within the second gripping hole to form the gripping portion. When the gripping portion is subjected to force and drives the first driving portion from the locking zone to the unlocking zone, the first locking portion is in a first state. In one possible implementation, the support member includes a support plate and a support cover. The support plate includes an accommodating cavity, and the driving member and at least a portion of the locking member are disposed within the accommodating cavity. The support cover is detachably connected to the support plate and covers the accommodating cavity. The second gripping holes are two in number, one of which is disposed on the support plate and the other is disposed on the support cover, facing each other. The support cover also includes a communication hole, which is disposed opposite the first locking portion and allows the first locking portion to pass through. According to a second aspect of an embodiment of the present disclosure, a liquid-cooled switch is provided, comprising a housing and a self-locking mechanism as described in any one of the first aspects. Since the liquid-cooled switch provided in this embodiment includes the self-locking mechanism of the first aspect, the effects of the self-locking mechanism of the first aspect are also achieved by the liquid-cooled switch of this embodiment, and will not be further described here. According to a third aspect of an embodiment of the present disclosure, an equipment cabinet is provided, comprising a cabinet body and the liquid-cooled switch described in the second aspect, wherein the liquid-cooled switch is mounted to the cabinet body via the self-locking mechanism. Since the liquid-cooled switch includes the self-locking mechanism described in the first aspect, the effects of the self-locking mechanism in the first aspect are also achieved by the equipment cabinet of the present embodiment and will not be further described here. In addition to the technical problems solved by the present embodiment, the technical features constituting the technical solution, and the beneficial effects brought about by these technical features, other technical problems solved by the self-locking mechanism, liquid-cooled switch, and equipment cabinet provided by the present embodiment, other technical features included in the technical solution, and the beneficial effects brought about by these technical features will be further described in detail in the specific embodiments.BRIEF DESCRIPTION OF THE DRAWINGS To more clearly illustrate the embodiments of the present disclosure or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art.

The inventors discovered that this problem arises because multiple bolt holes are typically provided on the liquid-cooled switch and the equipment cabinet, and bolts are used to secure the liquid-cooled switch to the equipment cabinet. However, actual installation requires the use of installation tools and multiple locations, resulting in time-consuming and complex installation. In view of this, embodiments of the present disclosure provide a self-locking mechanism, a liquid-cooled switch, and an equipment cabinet. The self-locking mechanism includes a locking member and a driving member. The locking member includes a first locking portion, which has a first state and a second state. The driving member is connected to the first locking portion and is configured to switch the first locking portion between the first state and the second state. When the driving member drives the first locking portion to the second state, the self-locking mechanism and the support component can be quickly locked, for example, the self-locking mechanism and the equipment cabinet can be quickly locked. When the driving member drives the first locking portion to move it into the first state, the self-locking mechanism and the support component are quickly unlocked, facilitating quick separation of the self-locking mechanism from the support component, for example, facilitating quick unlocking and separation of the self-locking mechanism from the equipment cabinet. Compared to related art installation techniques, this eliminates the need for additional installation tools, saving installation or removal time between the self-locking mechanism and the support component, reducing installation costs, and improving installation efficiency. To make the above-mentioned objects, features, and advantages of the embodiments of the present disclosure more readily understood, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present disclosure, and are not exhaustive. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without inventive effort are within the scope of protection of the present disclosure. Referring to Figures 1 to 16, the present embodiment provides a self-locking mechanism 100 that can achieve quick locking or unlocking with a support component. It should be noted that the self-locking mechanism 100 itself may include a component to be secured, thereby directly achieving a fixed connection between the component to be secured and the supporting component. The self-locking mechanism 100 may also be an intermediate component for achieving a fixed connection between the component to be secured and the supporting component. For example, the component to be secured may be the housing 200 of a liquid-cooled switch (see FIG. 17 ), and the self-locking mechanism 100 may be detachably connected to the housing 200. The supporting component may be an equipment cabinet, thereby enabling rapid locking or unlocking between the liquid-cooled switch and the equipment cabinet.Continuing with reference to Figures 1 and 3 , the self-locking mechanism 100 includes a support member 110, a locking member 120, and a driving member 130. The support member 110 serves as the main structural member of the self-locking mechanism 100 and is used to support the other components of the self-locking mechanism 100. For example, the support member 110 is used to support the locking member 120, the driving member 130, or other components of the self-locking mechanism 100. The support member 110 can be a plate structure or a box structure. As a possible implementation, when the support member 110 is a plate structure, the support member 110 can include a support plate, and the locking member 120 and the driving member 130 can be disposed on a surface of the support member 110. This allows for quick installation and removal of the locking member 120 and the driving member 130, thereby reducing the time required to install the locking member 120 and the driving member 130 on the support member 110. As another possible implementation, referring to Figures 1, 5, and 6, the support member 110 includes a support plate 111 and a support cover 112. The support plate 111 includes a receiving cavity 113 with an opening. The support cover 112 is detachably connected to the support plate 111 and covers the receiving cavity 113, specifically, the support cover 112 can cover the opening of the receiving cavity 113. This arrangement facilitates the installation of the driver 130 and at least a portion of the locking member 120 into the receiving cavity 113 through the opening. Furthermore, it prevents the driver 130 and a portion of the locking member 120 from being exposed to the outside world, reducing the risk of collision and contamination by water vapor and increasing the service life of the driver 130 and the locking member 120. In this embodiment, referring to Figure 5, the support plate 111 is provided with at least two connecting posts 114, each of which has a threaded hole therein. The support cover 112 is provided with connection holes opposite the connection posts 114. The threaded sections of the bolts can be sequentially passed through the connection holes and screwed into the threaded holes of the connection posts 114, thereby achieving a detachable connection between the support cover 112 and the support plate 111. It should be understood that the thickness of the support plate 111 can be uniform throughout or vary. For example, the support plate 111 includes a first support plate 1111 and a second support plate 1112, which is connected to the first support plate 1111. The two support plates can be separate or integral. An integral structure not only improves the structural strength of the support plate 111 but also facilitates manufacturing.The thickness of the first support plate 1111 is greater than that of the second support plate 1112. The accommodating cavity 113 is provided on the first support plate 1111. This arrangement reduces the overall thickness and, consequently, the weight of the support plate 111. This reduces the pulling force exerted on other components when the self-locking mechanism 100 is installed. For example, this reduces the pulling force on the housing of a liquid-cooled switch, thereby improving the safety and service life of the housing. A portion of the second support plate 1112 is formed along a protrusion facing away from the bottom surface of the second support plate 1112 to form a reinforcing plate 1113. The reinforcing plate 1113 extends along the length of the second support plate 1112, i.e., along the X direction in FIG. 6 . Both the first support plate 1111 and the reinforcement plate 1113 are provided with weight-reducing grooves 1114. This reduces the weight of the support plate 111 without compromising the overall structural strength of the support plate 111, thereby achieving a lightweight support member 110. It should be noted that in this embodiment, the length of the support cover 112 is shorter than that of the first support plate 1111. The weight-reducing grooves 1114 can be formed between the edge of the support cover 112 adjacent to the second support plate 1112 and the reinforcement plate 1113. The number of weight-reducing grooves 1114 provided on the first support plate 1111 and the number of weight-reducing grooves 1114 provided on the reinforcement plate 1113 can both be multiple. The multiple weight-reducing grooves 1114 on the first support plate 1111 can be spaced apart along the width of the first support plate 1111, while the weight-reducing grooves 1114 on the reinforcement plate 1113 can be spaced apart along the length of the second support plate 1112. The locking member 120 is disposed on the support member 110. Exemplarily, the locking member 120 is disposed on the support plate 111 and is at least partially located within the accommodating cavity 113. The locking member 120 includes a first locking portion 121, which is movably connected to the support member 110. Referring again to Figures 1 and 2, the first locking portion 121 is movable relative to the support member 110. For example, the first locking portion 121 can move toward or away from the support member 110, allowing the first locking portion 121 to have a first state and a second state. When the first locking portion 121 is in the first state, the self-locking mechanism 100 is in an unlocked state; when the first locking portion 121 is in the second state, the self-locking mechanism 100 is in a locked state. The driving member 130 is movably disposed on the support member 110 and is connected to the first locking portion 121.The driving member 130 drives the first locking portion 121 to move, causing the first locking portion 121 to transition between the first state and the second state. It should be noted that when the first support member 110 is a box-type structure, a communication hole 1121 is defined in the support cover 112 of the first support member 110. The communication hole 1121 is disposed opposite the first locking portion 121, allowing the first locking portion 121 to pass through. In other words, the first locking portion 121 can be easily retracted into the accommodating cavity 113 through the communication hole 1121, or extended out of the accommodating cavity 113 through the communication hole 1121. In this embodiment, the state in which the first locking portion 121 moves away from the support member 110 and is in place can be either the first state or the second state. That is, when the driving member 130 drives the first locking portion 121 to move in a direction away from the support member 110 and into position, the first state is defined as the first state. Accordingly, the first locking portion 121 can be in a second state when it moves in a direction toward the support member 110 and into position. Conversely, when the driving member 130 drives the first locking portion 121 to move in a direction away from the support member 110 and into position, the second state is defined as the second state. Accordingly, the first locking portion 121 can be in a first state when it moves in a direction toward the support member 110 and into position. It should be understood that whether the driving member 130 drives the first locking portion 121 to move in a direction toward the support member 110 and into position, or whether the driving member 130 drives the first locking portion 121 to move in a direction away from the support member 110 and into position, is defined in conjunction with the structures of other cooperating components. To facilitate description of the relationship between the relative position of the first locking portion 121 relative to the support member 110 and the first and second states, let's use the self-locking mechanism 100 and an equipment cabinet as an example. Specifically, the self-locking mechanism 100 and the equipment cabinet can be quickly unlocked or locked. By way of example, the equipment cabinet includes a second locking portion 300 that mates with the first locking portion 121. In one example, referring to FIG7 , the first locking portion 121 is a locking protrusion, and the second locking portion 300 is a locking hole. When the driver 130 drives the first locking portion 121 toward the second locking portion 300, i.e., the driver 130 drives the first locking portion 121 away from the support member 110 and inserts it into the second locking portion 300, the first locking portion 121 is in the second state, i.e., the self-locking mechanism 100 is in the locked state.When the driver 130 drives the first locking portion 121 to move away from the second locking portion 300, i.e., when the driver 130 drives the first locking portion 121 to move toward the support member 110, the first locking portion 121 disengages from the second locking portion 300, placing the first locking portion 121 in the first state, i.e., the self-locking mechanism 100 in the unlocked state. In another example, referring to FIG8 , the first locking portion 121 may be a locking hole and a locking push rod movably connected to the locking hole, and the second locking portion 300 may be a locking protrusion, which may be located in the locking hole. When the driver 130 drives the first locking portion 121 toward the second locking portion 300, that is, the driver 130 drives the locking push rod of the first locking portion 121 to move in a direction away from the support member 110, and contacts the locking protrusion located in the locking hole, thereby pushing the locking protrusion away from the locking hole, thereby separating the first locking portion 121 from the second locking portion 300, so that the first locking portion is in the first state, that is, the self-locking mechanism 100 is in the unlocked state. When the driver 130 drives the first locking portion 121 to move away from the second locking portion 300, that is, the driver 130 drives the locking push rod of the first locking portion 121 to move in a direction toward the support member 110, the locking rod of the first locking portion 121 is retracted. The locking push rod of the first locking portion 121 does not contact the second locking portion 300. The second locking portion 300 can rely on an external force, such as the elastic restoring force of a spring, to drive the second locking portion 300 toward the first locking portion 121 and insert it into the locking hole, thereby locking the first locking portion 121 with the second locking portion 300. This puts the first locking portion 121 in the second state, i.e., the self-locking mechanism 100 in the locked state. Regardless of the above implementation method, the driving member 130 can drive the first locking portion 121 to move, thereby switching the first locking portion 121 between the first state and the second state, thereby switching the self-locking mechanism 100 between the locked state and the unlocked state. This arrangement facilitates rapid locking or unlocking of the self-locking mechanism 100 from the support component. For example, it facilitates rapid locking or unlocking of the self-locking mechanism 100 from the equipment cabinet. Compared to related art, this eliminates the need for additional installation tools, thus reducing installation or removal time between the self-locking mechanism 100 and the support component, lowering installation costs and improving installation efficiency. It should be understood that the movable direction of the driver 130 and the movable direction of the first locking portion 121 may be the same or different.In one example, when the driver 130 is a pneumatic cylinder, the output end of the driver 130 can be connected to the surface of the first locking portion 121 facing the support plate 111. For example, in the orientations shown in Figures 2 and 4 , the output end of the driver 130 can be connected directly behind the first locking portion 121, with the driver 130 driving the first locking portion 121 to perform telescopic movement. In another example, the movement direction of the driver 130 differs from that of the first locking portion 121. For example, the movement directions of the driver 130 and the first locking portion 121 intersect with each other. Referring to Figure 3 , the movement direction of the driver 130 can be parallel to the longitudinal direction of the support plate 111, i.e., the direction of the driver 130 is the X direction in Figure 3 . The movement direction of the first locking portion 121 is perpendicular to the support plate 111, i.e., the movement direction of the first locking portion 121 is the Z direction in Figure 3 . It should be noted that in this example, the output end of the driver 130 can be connected to the first locking portion 121 via a rotating component, allowing the first locking portion 121 to move in a direction perpendicular to the support plate 111. The rotating component can be part of the locking member 120 or a separate component, and this is not specifically limited in this embodiment. In this example, the driver 130 can be disposed on one side of the locking member 120. This avoids increasing the height of the self-locking mechanism 100 in a direction perpendicular to the support plate 111, thereby improving the height stability of the self-locking mechanism 100. In one possible implementation, one end of the locking member 120 is rotatably connected to the support member 110. In other words, one end of the locking member 120 is rotatably connected to the support plate 111 and is located within the accommodating cavity 113 of the support member 110. The locking member 120 itself includes a rotating component and is rotatably connected to the support member 110 via its own rotating component. For example, referring to Figures 9 to 11 , the locking member 120 includes a locking plate 122 and a rotating shaft 123. The rotating shaft 123 is disposed at one end of the locking plate 122 in the longitudinal direction and is opposite the first locking portion 121. The locking member 120 is rotatably connected to the support member 110 via the rotating shaft 123. It should be noted that the number of rotating shafts 123 can be one or two. When there is only one rotating shaft 123, the length of the rotating shaft 123 is greater than the width of the locking plate 122, which facilitates the rotational connection between the rotating shaft 123 and the support member 110. When there are two rotating shafts 123, the two rotating shafts 123 are located on either side of the locking plate 122 in the width direction of the locking plate 122 and are rotatably connected to the support member 110.For example, referring to Figures 3, 5, and 6, two rotating supports 1115 are provided on the first support plate 1111. Each rotating support 1115 has a rotating groove, and each rotating shaft 123 is rotatably connected within a corresponding rotating groove. Referring to Figures 9 to 11, the locking member 120 also includes a locking groove 124. The locking groove 124 and the first locking portion 121 are spaced apart on the locking plate 122. In other words, the locking groove 124 is located between the first locking portion 121 and the rotating shaft 123. The locking groove 124 has interconnected locking and unlocking zones. Further referring to Figures 3 and 4, the driving member 130 includes a first driving portion 131, which is movably connected within the locking groove 124. The first driving portion 131 can move between a locking zone and an unlocking zone. When the first driving portion 131 moves between the locking zone and the unlocking zone, the locking member 120 rotates relative to the support member 110, thereby switching the first locking portion 121 between a first state and a second state. For example, when the first driving portion 131 is in the unlocking zone, the first locking portion 121 is in the first state; when the first driving portion 131 is in the locking zone, the first locking portion 121 is in the second state. It should be noted that, in one example, the first driving portion 131 can drive the first locking portion 121 to reciprocate between the locking zone and the unlocking zone to achieve the transition between the first state and the second state. For example, the driving member 130 can be a driving cylinder, the end of the cylinder rod of which constitutes the first driving portion 131. The telescopic movement of the driving cylinder enables the first driving portion 131 to move between the locking zone and the unlocking zone. In another example, the first driving portion 131 can drive the first locking portion 121 from the locked zone to the unlocked zone, thereby placing the first locking portion 121 in the unlocked state. The movement of the first locking portion 121 from the unlocked zone to the locked zone can be accomplished by another driving component. For example, referring to Figures 3, 12, and 13, the self-locking mechanism 100 also includes a second driving portion 132, one end of which is connected to the support member 110, and the other end of which is connected to the first driving portion 131. When the first driving portion 131 of the driving member 130 moves from the locked zone to the unlocked zone, the first locking portion 121 is placed in the first state, thereby placing the self-locking mechanism 100 in the unlocked state. Subsequently, the second driving portion 132 can drive the first driving portion 131 from the unlocked zone to the locked zone, thereby placing the first locking portion 121 in the second state, thereby placing the self-locking mechanism 100 in the locked state.Referring to Figures 1 and 7 , when the first driving portion 131 of the driving member 130 moves from the locking zone to the unlocking zone, the first driving portion 131 can drive the first locking portion 121 to move in a direction away from the first support plate 111. Specifically, the first driving portion 131 drives the first locking portion 121 to move outside the accommodating chamber 113 through the communicating hole 1121, thereby placing the first locking portion 121 in the first state. Subsequently, or alternatively, referring to Figures 1 and 8 , when the first driving portion 131 of the driving member 130 moves from the locking zone to the unlocking zone, the first driving portion 131 can drive the first locking portion 121 to move toward the first support plate 111. Specifically, the first driving portion 131 drives the first locking portion 121 to retract into the accommodating chamber 113 through the communicating hole 1121, thereby placing the first locking portion 121 in the first state. Afterwards, the second driving portion 132 drives the driving member 130 from the unlocking zone to the locking zone, placing the first locking portion 121 in the second state. In this embodiment, the first and second driving portions 131, 132 jointly enable the first locking portion 121 to transition between the first and second states, thereby improving the accuracy of the movement of the first locking portion 121. As a possible embodiment of the second driving portion 132, please refer to Figures 3, 4, 6, and 16. The support member 110 is provided with a mounting support 115, and the driving member 130 defines a mounting cavity 133, with at least a portion of the mounting support 115 located within the mounting cavity 133. The inner wall of the mounting cavity 133, which is opposite the mounting support 115, is connected to the mounting support 115 via an elastic member. The elastic member constitutes the second driving portion 132. In this example, the elastic member comprises a spring. Taking the orientation shown in FIG. 4 as an example, the inner wall of the mounting cavity 133 opposite the mounting support 115 is the right inner wall of the mounting cavity 133. In this embodiment, an elastic member is used as the second driving portion 132 to drive the first driving portion 131 from the unlocking zone to the locking zone. This not only guides the movement of the first driving portion 131 but also provides vibration reduction. To facilitate the description of the working state of the second driving portion 132, the embodiments shown in FIG. 1 , FIG. 3 , and FIG. 7 are used as examples for detailed description.Continuing with Figures 3 and 4 , when the first driving portion 131 of the driving member 130 moves from the locking zone to the unlocking zone, that is, from right to left, the first driving portion 131 of the driving member 130 continuously compresses the elastic member during this movement, driving the first locking portion 121 toward the first support plate 111 and retracting it into the accommodating cavity 113, placing the first locking portion 121 in the first state. When no external force is applied to the first driving portion 131 of the driving member 130, the elastic restoring force of the elastic member drives the first driving portion 131 from the unlocking zone to the locking zone. During this movement, the elastic member also drives the first locking portion 121 to move away from the first support plate 111, extending out of the accommodating cavity 113, placing the first locking portion 121 in the second state. In this embodiment, at least a portion of the mounting support 115 is located within the mounting cavity 133. The mounting support 115 and the inner wall of the mounting cavity 133 can be used to limit the range of the second driving portion 132, ensuring that the first locking portion 121 can accurately transition between the first and second states. When the second driving portion 132 drives the first driving portion 131 from the unlocking zone to the locking zone, the first locking portion 121 can rotate about the rotation axis 123 to achieve movement away from the first support plate 111. Other auxiliary components may also be included. For example, referring to Figures 4, 13, and 15, the self-locking mechanism 100 also includes an elastic return member 140. The elastic return member 140 includes a first connecting end 141, a second connecting end 142, and a spiral segment 143 connecting the first and second connecting ends 141, 142. The first and second connecting ends 141, 142 are respectively connected to the support member 110. The spiral section 143 is located above the locking member 120 and abuts against it. The elastic return member 140 may be a hook torsion spring. For example, referring to FIG6 , two connecting supports 116 are provided on the first support plate 111. The two connecting supports 116 are spaced apart along the width of the first support plate 111. Each connecting support 116 has a rotation groove. The first connecting end 141 is rotatably connected to one of the rotation grooves, and the second connecting end 142 is rotatably connected to the other rotation groove.When the second driving portion 132 drives the first driving portion 131 from the unlocking zone to the locking zone, the first driving portion 131 releases the restraint on the locking member 120. Specifically, the first driving portion 131 no longer applies a force to the locking member 120 toward the first support plate 111. The elastic return member 140 drives the first locking member 121 to rotate about the rotation axis of the locking member 120, placing the first locking member 121 in the second state. In other words, the elastic return member 140 drives the first locking member 121 to rotate about the rotation axis 123 and move in a direction away from the first support plate 111, extending out of the accommodating cavity 113 through the communicating hole 1121, placing the first locking member 121 in the second state. As a possible implementation of the locking and unlocking zones, please continue to refer to Figures 9 and 10. The locking groove 124 includes a first locking groove 1241 and a second locking groove 1242 that are relatively connected, with a smooth transition between the first locking groove 1241 and the second locking groove 1242. The first locking groove 1241 constitutes the unlocking zone, while the second locking groove 1242 constitutes the locking zone. Referring to Figures 3 and 11, when the first locking portion 121 is retracted into the accommodating cavity 113, the unlocked state is reached, and the depth of the first locking groove 1241 is less than the depth of the second locking groove 1242. During actual operation, when an external force is applied to the driver 130, the first driver 131 moves from the second locking groove 1242 toward the first locking groove 1241 until it moves into the first locking groove 1241. During this process, the first driver 131 applies a force toward the first support plate 111 to the locking member 120, pressing the locking member 120 downward. This causes the first locking member 121 to move into the accommodating cavity 113, placing the first locking member 121 in the first state. When no external force is applied to the driver 130, the elastic restoring force of the second driver 132 causes the first driver 131 to move from the first locking groove 1241 to the second locking groove 1242. Because the depth of the second locking groove 1242 is greater than that of the first locking groove 1241, the first driver 131 no longer applies a force to the locking member 120, leaving the locking member 120 in a free state. At this point, the elastic return member 140 drives the first locking portion 121 to rotate about the rotation axis 123 and move in a direction away from the first support plate 111, thereby extending out of the accommodating cavity 113 through the communication hole 1121, placing the first locking portion 121 in the second state. It should be noted that when the first locking portion 121 extends out of the accommodating cavity 113 (the unlocked state), the depth of the first locking groove 1241 is greater than the depth of the second locking groove 1242.The specific operating principle is similar to that described above, and this embodiment will not be further described here. In this embodiment, the number of first locking portions 121 can be one or more. Exemplarily, there are two first locking portions 121. Continuing with Figures 9 and 10, the locking plate 122 further includes a notch 125. The notch 125 extends through the locking plate 122 along its thickness, with the open end of the notch 125 facing the driver 130. In other words, the notch 125 is a through-slot extending vertically and open at one end. Specifically, the notch 125 extends through one side of the locking plate 122 in a direction away from the rotation axis 123, giving the notch 125 a U-shaped structure. This notch 125 provides installation space, allowing a portion of the driver 130 or other components to be positioned within the notch 125, thereby saving installation space and reducing the size of the self-locking mechanism 100. On the other hand, the notch 125 also functions as a weight-reducing slot, reducing the weight of the locking plate 122 and, consequently, the weight of the self-locking mechanism 100, thereby improving the user experience. The notch 125 divides the locking plate 122 and its corresponding area into two parts. This allows for an increased number of first locking portions 121. For example, there can be two first locking portions 121, one located on either side of the notch 125. This improves the connection stability between the self-locking mechanism 100 and the supporting component, for example, between the self-locking mechanism 100 and the equipment cabinet. It should be noted that the first locking portion 121 and the locking plate 122 can be separate components or a single piece. When the first locking portion 121 and the locking plate 122 are a single piece, they can be manufactured integrally through injection molding or casting, which reduces the difficulty of manufacturing the locking member 120 and improves its structural strength. When the first locking portion 121 includes a latching protrusion, the longitudinal cross-section of the first locking portion 121 is triangular, or alternatively, the longitudinal cross-section of the first locking portion 121 is trapezoidal, with the longitudinal cross-section perpendicular to the surface of the locking plate 122. This arrangement increases the contact area between the first locking portion 121 and the mating second locking portion 300, thereby enhancing the locking strength of the self-locking mechanism 100. In one possible embodiment, referring to Figures 12 and 16 , the driver 130 includes a driver plate 134 and two driver arms 135 . The two driver arms 135 are connected to the driver plate 134 and are located on either side of the locking member 120.In other words, the driving arms 135 are spaced apart to create an installation space between the two driving arms 135. This facilitates installation of the locking member 120 within the installation space, thereby reducing the size of the self-locking mechanism 100 and facilitating the development of the self-locking mechanism 100 towards small-size integration. The driving plate 134, located on portions of adjacent driving arms 135, protrudes toward the locking member 120 to form a protrusion 136. The installation cavity 133 is formed on the protrusion 136 and extends through the protrusion 136 along the thickness of the protrusion 136. The end of each driving arm 135, facing away from the driving plate 134, is bent toward the locking member 120 to form a first driving portion 131. In this embodiment, there are two first driving portions 131. This arrangement increases the number of connection points between the driving member 130 and the locking member 120, further facilitating the stability of the locking member 120 transitioning between the first and second states. It should be noted that the movement of the first driving portion 131 of the driving member 130 can be driven by mechanical equipment, for example, using a cylinder or other component, or manually by an operator. For example, a first gripping hole 137 is provided on the driving plate 134, and a second gripping hole 117 is provided on the support member 110. The first gripping hole 137 and the second gripping hole 117 are disposed opposite and interconnected. It should be understood that when the support member 110 includes a support plate 111 and a support cover 112, there are two second gripping holes 117, one of which is provided on the support plate 111 and the other on the support cover 112. The two second gripping holes 117 are disposed opposite and interconnected with the first gripping hole 137. Referring to FIG. 1 , a portion of the driving plate 134 is exposed within the second gripping hole 117 to form a gripping portion. When the grip is subjected to force, it drives the first driving portion 131 to move from the locked zone to the unlocked zone, placing the first locking portion 121 in the first state. Taking the positions shown in Figures 1 and 3 as an example, when the operator grasps the grip, the driving plate 134 moves away from the locking member 120, thereby driving the first driving portion 131 from the locked zone to the unlocked zone, placing the first locking portion 121 in the first state. It should be noted that when the first locking portion 121 extends out of the accommodating cavity 113, representing the unlocked state, the grip is subjected to force, driving the first driving portion 131 from the locked zone to the unlocked zone, placing the first locking portion 121 in the first state.Taking the positions shown in Figures 1 and 3 as an example, when an operator grasps the grip, the drive plate 134 moves toward the locking member 120, thereby driving the first drive portion 131 from the locked zone to the unlocked zone, placing the first locking portion 121 in the first state. Referring to Figure 17 , an embodiment of the present disclosure also provides a liquid-cooled switch, which is used to dissipate heat for servers or other equipment in a data center. Therefore, the liquid-cooled switch needs to be installed on the body of an equipment cabinet. The liquid-cooled switch includes a housing 200 and a self-locking mechanism 100 provided in any of the above-mentioned embodiments. The self-locking mechanism 100 is disposed on the housing 200 and enables quick removal or installation between the liquid-cooled switch and the equipment cabinet. The structure and principle of the self-locking mechanism 100 can be found in the description of any of the above-mentioned embodiments and will not be further elaborated in this embodiment. It should be noted that the number of self-locking mechanisms 100 in this embodiment can be one or more. Illustratively, if there are two self-locking mechanisms 100 and the liquid-cooled switch housing 200 is square, the two self-locking mechanisms 100 can be located on either side of the housing 200 in the width direction. This arrangement can ensure the stability between the liquid-cooled switch and the equipment cabinet housing. The present disclosure also provides an equipment cabinet comprising a cabinet body and the liquid-cooled switch described in the above embodiment. The liquid-cooled switch is mounted to the cabinet body via a self-locking mechanism. Illustratively, the cabinet body is provided with a second locking portion 300 that cooperates with the first locking portion 121 to achieve relative fixation or separation between the liquid-cooled switch and the cabinet body. Since the liquid-cooled switch includes the self-locking mechanism described in the first aspect, the effects of the self-locking mechanism in the first aspect are also achieved by the equipment cabinet in the present disclosure and will not be further elaborated here.

Industrial Applicability: The self-locking mechanism provided in the embodiments of the present disclosure includes a locking member and a driving member. The locking member includes a first locking portion, which has a first state and a second state. The driving member is connected to the first locking portion and is configured to switch the first locking portion between the first state and the second state. When the driving member drives the first locking portion to move it to the second state, the self-locking mechanism can quickly lock with the support component, for example, the self-locking mechanism can quickly lock with the equipment cabinet. When the driving member drives the first locking portion to move so as to be in the first state, the self-locking mechanism and the support component are quickly unlocked, so that the self-locking mechanism and the support component can be quickly separated, for example, so that the self-locking mechanism and the equipment cabinet can be quickly unlocked and separated, thereby solving the technical problem of low installation efficiency between the self-locking mechanism and the support component.
