[0064] As described in the background art, the installation between the liquid-cooled switch and the equipment cabinet is rather cumbersome. Through research by the inventor, it is found that the reason for this problem is that usually, a plurality of bolt holes need to be provided on the liquid-cooled switch and the equipment cabinet, and the liquid-cooled switch is fixed to the equipment cabinet by bolts. However, during actual installation, installation tools need to be used and operations need to be carried out at multiple points, which has the defects of time-consuming installation and complex installation.

[0065] In view of this, the embodiments of the present application provide a self-locking mechanism, a liquid-cooled switch, and an equipment cabinet. Among them, the self-locking mechanism includes a locking member and a driving member. The locking member includes a first locking portion, and the first locking portion includes a first state and a second state; the driving member is connected to the first locking portion and is used to convert the first locking portion between the first state and the second state. When the driving member drives the first locking portion to move to the second state, the quick locking of the self-locking mechanism and the supporting member can be realized. For example, the quick locking of the self-locking mechanism and the equipment cabinet can be realized. When the driving member drives the first locking portion to move to the first state, the quick unlocking of the self-locking mechanism and the supporting member is realized, so as to quickly separate the self-locking mechanism from the supporting member. For example, to quickly unlock and separate the self-locking mechanism and the equipment cabinet. Compared with the related art, there is no need to use additional installation tools for installation, which is beneficial to saving the installation time or disassembly time between the self-locking mechanism and the supporting member, reducing the installation cost, and improving the installation efficiency.

[0066] In order to make the above objects, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0067] Please refer to the attached Figure 1 to the attached Figure 16 , the embodiments of the present application provide a self-locking mechanism 100, and the self-locking mechanism 100 can realize quick locking or unlocking with the supporting member. It should be noted that the self-locking mechanism 100 itself can include a component to be fixed, so that the fixed connection between the component to be fixed and the supporting member can be directly realized. The self-locking mechanism 100 can also be an intermediate component for realizing the fixed connection between the component to be fixed and the supporting member. Exemplarily, the component to be fixed can be the casing 200 of the liquid-cooled switch (please refer to the attached Figure 17 ), and the self-locking mechanism 100 can be detachably connected to the casing 200; the supporting member can be an equipment cabinet, so that the quick locking or unlocking between the liquid-cooled switch and the equipment cabinet can be realized.

[0068] Please continue to refer to the attached Figure 1 and the attached Figure 3 , the self-locking mechanism 100 includes a support member 110, a locking member 120, and a driving member 130. The support member 110 is used as the main structural member of the self-locking mechanism 100 to support 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.

[0069] 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 arranged on the surface of the support member 110. In this way, the quick installation and disassembly of the locking member 120 and the driving member 130 can be realized, which is beneficial to reducing the installation time of the locking member 120 and the driving member 130 with the support member 110. As another possible implementation, please refer to the attached Figure 1 attachment Figure 5 attachment Figure 6 attachment

[0070] In this embodiment, please refer to the attached Figure 5 attachment

[0071] It should be understood that the thickness of the support plate 111 can be equal everywhere or unequal. Exemplarily, the support plate 111 includes a first support plate 1111 and a second support plate 1112. The second support plate 1112 is connected to the first support plate 1111, and the two can be a split structure or an integral structure. When the two are an integral structure, not only the structural strength of the support plate 111 can be improved, but also the manufacturing can be facilitated.

[0072] Among them, the thickness of the first support plate 1111 is greater than the thickness of the second support plate 1112; the accommodation cavity 113 is arranged on the first support plate 1111; by such an arrangement, the overall thickness of the support plate 111 can be reduced, and further the overall weight of the support plate 111 can be reduced, so as to reduce the pulling force on other components when the self-locking mechanism 100 is installed with other components. For example, the pulling force on the housing of the liquid-cooled switch can be reduced, and the safety and service life of the housing of the liquid-cooled switch are improved.

[0073] A part of the second support plate 1112 protrudes 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 direction of the second support plate 1112, that is, the reinforcing plate 1113 extends along the X direction in Figure 6 FIG. In addition, weight-reducing grooves 1114 are provided on both the first support plate 1111 and the reinforcing plate 1113. Without reducing the overall structural strength of the support plate 111, the weight of the support plate 111 can be reduced, realizing the light weight of the support member 110.

[0074] It should be noted that in this embodiment, the length of the support cover 112 is less than the length of the first support plate 1111. The weight-reducing groove 1114 can be formed between the edge of the support cover 112 close to the second support plate 1112 and the reinforcing 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 reinforcing plate 1113 can both be multiple. Among them, the multiple weight-reducing grooves 1114 located on the first support plate 1111 can be arranged at intervals along the width direction of the first support plate 1111; the weight-reducing grooves 1114 located on the reinforcing plate 1113 can be arranged at intervals along the length direction of the second support plate 1112.

[0075] The locking member 120 is provided on the support member 110. Exemplarily, the locking member 120 is provided on the support plate 111 and at least partially located in the accommodation cavity 113. The locking member 120 includes a first locking portion 121, and the first locking portion 121 is movably connected to the support member 110. Please continue to refer to Figure 1 and Figure 2 . In other words, the first locking portion 121 can move relative to the support member 110. For example, the first locking portion 121 can move in the direction towards the support member 110 and can also move in the direction away from the support member 110, so that the first locking portion 121 has a first state and a second state. Among them, when the first locking portion 121 is in the first state, the self-locking mechanism 100 is in the unlocked state; when the first locking portion 121 is in the second state, the self-locking mechanism 100 is in the locked state.

[0076] The driving member 130 is movably provided 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, so that the first locking portion 121 is switched between the first state and the second state. It should be noted that when the first support member 110 is a box structure, a communication hole 1121 is provided on the support cover 112 of the first support member 110. The communication hole 1121 is disposed opposite to the first locking portion 121 for the first locking portion 121 to pass through. In other words, it is convenient for the first locking portion 121 to retract into the accommodation cavity 113 through the communication hole 1121, or to extend out of the accommodation cavity 113 through the communication hole 1121.

[0077] In this embodiment, the first locking portion 121 moves in a direction away from the support member 110, and the state where it moves into place can be the first state or the second state. That is to say, when the driving member 130 drives the first locking portion 121 to move in a direction away from the support member 110 and the state where it moves into place is the first state, correspondingly, when the first locking portion 121 moves in a direction towards the support member 110 and moves into place, the state can be the second state. Conversely, when the driving member 130 drives the first locking portion 121 to move in a direction away from the support member 110 and the state where it moves into place is the second state, correspondingly, when the first locking portion 121 moves in a direction towards the support member 110 and moves into place, the state can be the first state.

[0078] It should be understood that the state where the driving member 130 drives the first locking portion 121 to move in a direction towards the support member 110 and moves into place being the first state, or the state where the driving member 130 drives the first locking portion 121 to move in a direction away from the support member 110 and moves into place being the first state, needs to be cooperatively defined with the structures of other cooperating components. For the convenience of describing the relationship between the relative position of the first locking portion 121 with respect to the support member 110 and the first and second states, let's take the self-locking mechanism 100 and the equipment cabinet as an example for elaboration, that is, the self-locking mechanism 100 and the equipment cabinet can be quickly unlocked or locked.

[0079] Exemplarily, the equipment cabinet has a second locking portion 300, and the second locking portion 300 cooperates with the first locking portion 121. In one example, please refer to the attached Figure 7 , the first locking portion 121 is a locking protrusion, and the second locking portion 300 is a locking hole. When the driving member 130 drives the first locking portion 121 to move towards the second locking portion 300, that is, the driving member 130 drives the first locking portion 121 to move in a direction away from the support member 110 and is inserted into the second locking portion 300, so that the first locking portion 121 is in the second state, that is, the self-locking mechanism 100 is in the locked state. When the driving member 130 drives the first locking portion 121 to move away from the second locking portion 300, that is, the driving member 130 drives the first locking portion 121 to move in a direction towards the support member 110, the first locking portion 121 disengages from the second locking portion 300, so that the first locking portion 121 is in the first state, that is, the self-locking mechanism 100 is in the unlocked state.

[0080] In another example, please refer to the attached Figure 8, the first locking part 121 can be a locking hole and a locking push rod movably connected in the locking hole, and the second locking part 300 can be a locking protrusion, and the locking protrusion can be located in the locking hole. When the driving member 130 drives the first locking part 121 to move towards the second locking part 300, that is, the driving member 130 drives the locking push rod of the first locking part 121 to move in a direction away from the support member 110 and contact the locking protrusion located in the locking hole, so as to push the locking protrusion away from the locking hole, realizing the separation of the first locking part 121 and the second locking part 300, so that the first locking part is in the first state, that is, the self-locking mechanism 100 is in the unlocked state.

[0081] When the driving member 130 drives the first locking part 121 to move away from the second locking part 300, that is, the driving member 130 drives the locking push rod of the first locking part 121 to move in a direction towards the support member 110, so that the locking rod of the first locking part 121 retracts; the locking push rod of the first locking part 121 does not contact the second locking part 300, and the second locking part 300 can rely on the action of an external force, for example, utilize the elastic restoring force of a spring, to drive the second locking part 300 to move towards the first locking part 121 and be inserted into the locking hole, realizing the locking of the first locking part 121 and the second locking part 300, so that the first locking part is in the second state, that is, the self-locking mechanism 100 is in the locked state.

[0082] Regardless of the above implementation method, the driving member 130 can drive the first locking part 121 to move, realizing the conversion of the first locking part 121 between the first state and the second state, and further enabling the self-locking mechanism 100 to be converted between the locked state and the unlocked state. Such a setting can facilitate the quick locking or quick unlocking and separation of the self-locking mechanism 100 and the support component. For example, it can facilitate the quick locking or quick unlocking and separation of the self-locking mechanism 100 and the equipment cabinet. Compared with the related art, it is no longer necessary to use an additional installation tool for installation, which is beneficial to saving the installation time or disassembly time between the self-locking mechanism 100 and the support component, reducing the installation cost, and improving the installation efficiency.

[0083] It should be understood that the moving direction of the driving member 130 and the moving direction of the first locking part 121 can be the same or different. In one example, when the driving member 130 is a cylinder, the output end of the driving member 130 can be connected to the surface of the first locking part 121 facing the support plate 111, so as to Figure 2 and Figure 4 Taking the orientation shown as an example, the output end of the driving member 130 can be connected to the exact rear of the first locking part 121, and the driving member 130 drives the first locking part 121 to perform a telescopic motion.

[0084] In another example, the moving direction of the driving member 130 is different from that of the first locking portion 121. For example, the moving directions of the driving member 130 and the first locking portion 121 intersect each other. Please refer to the attached Figure 3 , the moving direction of the driving member 130 may be parallel to the length direction of the support plate 111, that is, the direction of the driving member 130 is the Figure 3 X direction in the attached Figure 3 . The moving direction of the first locking portion 121 is perpendicular to the support plate 111, that is, the moving direction of the first locking portion 121 is the

[0085] Z direction in the attached

[0086] It should be noted that in this example, the output end of the driving member 130 may be connected to the first locking portion 121 through a rotating member, so that the first locking portion 121 can move in a direction perpendicular to the support plate 111. Among them, the rotating member may be a part of the locking member 120 or an independent component, and the specific limitation is not made in this embodiment. Figure 9 to the attached Figure 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 length direction and is disposed opposite to the first locking portion 121. The locking member 120 is rotatably connected to the support member 110 through the rotating shaft 123. It should be noted that the number of the rotating shafts 123 may be one or two. When the number of the rotating shafts 123 is one, the length of the rotating shaft 123 is greater than the width of the locking plate 122, which is beneficial to the rotational connection between the rotating shaft 123 and the support member 110. When the rotating shafts 123 are two, in the width direction of the locking plate 122, the two rotating shafts 123 are respectively located on both sides of the locking plate 122 and are rotatably connected to the support member 110. For example, please refer to the attached Figure 3 , the attached Figure 5 and the attached Figure 6 , two rotating supports 1115 are provided on the first support plate 1111, and each rotating support 1115 has a rotating groove, and each rotating shaft 123 is rotatably connected to the corresponding rotating groove.

[0087] Please refer to the attached Figure 9To the attached Figure 11 Moreover, the locking member 120 further includes a locking groove 124 which is spaced from the first locking portion 121 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.

[0088] The locking groove 124 has a locking area and an unlocking area which communicate with each other; please continue to refer to the attached Figure 3 and the attached Figure 4 Moreover, the driving member 130 includes a first driving portion 131 which is movably connected in the locking groove 124. The first driving portion 131 can move between the locking area and the unlocking area. When the first driving portion 131 moves in the locking area and the unlocking area, the locking member 120 rotates relative to the support member 110, so that the first locking portion 121 switches between the first state and the second state. Exemplarily, when the first driving portion 131 is located in the unlocking area, the first locking portion 121 is in the first state; when the first driving portion 131 is located in the locking area, the first locking portion 121 is in the second state.

[0089] 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 area and the unlocking area to realize the conversion of the first locking portion 121 between the first state and the second state. Exemplarily, the driving member 130 can be a driving cylinder, and the end of the cylinder rod of the driving cylinder constitutes the first driving portion 131. The first driving portion 131 moves between the locking area and the unlocking area through the telescopic movement of the driving cylinder.

[0090] In another example, the first driving portion 131 can drive the first locking portion 121 to move from the locking area to the unlocking area, so that the first locking portion 121 is in the unlocked state; and the movement of the first locking portion 121 from the unlocking area to the locking area can be completed by means of another driving member. Exemplarily, please refer to the attached Figure 3 、the attached Figure 12 and the attached Figure 13 Moreover, the self-locking mechanism 100 further includes a second driving portion 132. One end of the second driving portion 132 is connected to the support member 110, and the other end of the second driving portion 132 is connected to the first driving portion 131.

[0091] When the first driving portion 131 of the driving member 130 moves from the locking area to the unlocking area, the first locking portion 121 is in the first state, so that the self-locking mechanism 100 is in the unlocked state; thereafter, the second driving portion 132 can drive the first driving portion 131 to move from the unlocking area to the locking area, so that the first locking portion 121 is in the second state, and the self-locking mechanism 100 is in the locked state.

[0092] Please refer to the attached Figure 1 and the attached Figure 7, when the first driving part 131 of the driving part 130 moves from the locking area to the unlocking area, the first driving part 131 can drive the first locking part 121 to move in a direction away from the first support plate 111, that is, the first driving part 131 drives the first locking part 121 to move out of the accommodating cavity 113 through the communication hole 1121, so that the first locking part 121 is in the first state; then, or, please refer to the attached Figure 1 and attached Figure 8 , when the first driving part 131 of the driving part 130 moves from the locking area to the unlocking area, the first driving part 131 can drive the first locking part 121 to move in the direction towards the first support plate 111, that is, the first driving part 131 drives the first locking part 121 to retract into the accommodating cavity 113 through the communication hole 1121, so that the first locking part 121 is in the first state; then, the second driving part 132 is used to drive the driving part 130 to move from the unlocking area to the locking area, so that the first locking part 121 is in the second state.

[0093] In this embodiment, relying on the cooperation of the first driving part 131 and the second driving part 132 to realize the conversion of the first locking part 121 between the first state and the second state can improve the accuracy of the first locking part 121 during the moving process.

[0094] As a possible implementation manner of the second driving part 132, please refer to the attached Figure 3 、attached Figure 4 、attached Figure 6 and attached Figure 16 , an installation support 115 is provided on the support part 110, an installation cavity 133 is formed in the driving part 130, and at least part of the installation support 115 is located in the installation cavity 133; an elastic member is connected between the inner wall of the installation cavity 133 opposite to the installation support 115 and the installation support 115; wherein, the elastic member constitutes the second driving part 132; in this example, the elastic member includes a spring. Taking the orientation shown in the attached Figure 4 as an example, the inner wall of the installation cavity 133 opposite to the installation support 115 is the right inner wall of the installation cavity 133. In this embodiment, using the elastic member as the second driving part 132 to drive the first driving part 131 to move from the unlocking area to the locking area can, on the one hand, guide the movement of the first driving part 131, and on the other hand, play a role in shock absorption.

[0095] For the convenience of describing the working state of the second driving part 132, taking the solutions disclosed in the attached Figure 1 、attached Figure 3 and attached Figure 7 as an example, a detailed description will be given.

[0096] Please continue to refer to the attached Figure 3 and attached Figure 4, when the first driving part 131 of the driving part 130 moves from the locking area to the unlocking area, that is, the first driving part 131 of the driving part 130 moves from right to left, the elastic part is continuously compressed during the movement, and the first locking part 121 is driven to move towards the first support plate 111 to retract into the accommodating cavity 113, so that the first locking part 121 is in the first state. When no external force is applied to the first driving part 131 of the driving part 130, under the action of the elastic restoring force of the elastic part, the elastic part drives the first driving part 131 to move from the unlocking area to the locking area. During the movement, the first locking part 121 is driven to move in a direction away from the first support plate 111 to extend out of the accommodating cavity 113, so that the first locking part 121 is in the second state.

[0097] In this embodiment, at least part of the mounting seat 115 is located in the mounting cavity 133. The stroke size of the second driving part 132 can be limited by relying on the mounting seat 115 and the inner wall of the mounting cavity 133, so as to ensure that the first locking part 121 can accurately transform between the first state and the second state.

[0098] When the second driving part 132 drives the first driving part 131 to move from the unlocking area to the locking area, the first locking part 121 can rotate around the rotation axis 123 by itself to realize the movement of the first locking part 121 in a direction away from the first support plate 111, or there can be other auxiliary components.

[0099] Exemplarily, please refer to the appendix Figure 4 、appendix Figure 13 and appendix Figure 15 , the self-locking mechanism 100 further includes an elastic reset part 140. The elastic reset part 140 includes a first connection end 141, a second connection end 142, and a spiral section 143 connecting the first connection end 141 and the second connection end 142. The first connection end 141 and the second connection end 142 are respectively connected to the support part 110; the spiral section 143 is located above the locking part 120 and abuts against the locking part 120. Among them, the elastic reset part 140 can be a hook torsion spring. Exemplarily, please continue to refer to the appendix Figure 6 , two connection seats 116 are arranged on the first support plate 111. The two connection seats 116 are arranged at intervals along the width direction of the first support plate 111, and each connection seat 116 has a rotation groove; among them, the first connection end 141 is rotatably connected in one of the rotation grooves, and the second connection end 142 is rotatably connected in the other rotation groove.

[0100] When the second driving part 132 drives the first driving part 131 to move from the unlocking area to the locking area, the first driving part 131 releases the restriction on the locking part 120, that is, the first driving part 131 no longer applies a force towards the first support plate 111 to the locking part 120, and the elastic reset part 140 drives the first locking part 121 to rotate around the rotation axis of the locking part 120, so that the first locking part 121 is in the second state. In other words, the elastic reset part 140 drives the first locking part 121 to rotate around the rotation shaft 123 and move in a direction away from the first support plate 111, so as to extend out of the accommodating cavity 113 through the communication hole 1121, making the first locking part 121 in the second state.

[0101] As a possible implementation of the locking area and the unlocking area, please continue to refer to Appendix Figure 9 to Appendix Figure 10 , the locking groove 124 includes a first locking groove 1241 and a second locking groove 1242 that are relatively connected, wherein, the first locking groove 1241 and the second locking groove 1242 are smoothly transitioned. And the first locking groove 1241 constitutes the unlocking area; the second locking groove 1242 constitutes the locking area.

[0102] Please refer to Appendix Figure 3 and Appendix Figure 11 , when the first locking part 121 retracts into the accommodating cavity 113, it is in the unlocking state, then the depth of the first locking groove 1241 is less than the depth of the second locking groove 1242. During actual work, when an external force is applied to the driving part 130, the first driving part 131 moves from the second locking groove 1242 to the first locking groove 1241 until it moves into the first locking groove 1241. During this process, the first driving part 131 applies a force towards the first support plate 111 to the locking part 120, that is, presses the locking part 120 downward, and the first locking part 121 moves into the accommodating cavity 113, making the first locking part 121 in the first state.

[0103] When no external force is applied to the driving part 130, under the elastic restoring force of the second driving part 132, the first driving part 131 moves from the first locking groove 1241 to the second locking groove 1242. Since the depth of the second locking groove 1242 is greater than the depth of the first locking groove 1241, the first driving part 131 no longer provides a force to the locking part 120, making the locking part 120 in a free state. At this time, the elastic reset part 140 drives the first locking part 121 to rotate around the rotation shaft 123 and move in a direction away from the first support plate 111, so as to extend out of the accommodating cavity 113 through the communication hole 1121, making the first locking part 121 in the second state.

[0104] It should be noted that when the first locking portion 121 extends out of the accommodating cavity 113 to be in the unlocked state, the depth of the first locking groove 1241 is greater than the depth of the second locking groove 1242. The specific working principle is similar to the above, and will not be elaborated in this embodiment.

[0105] In this embodiment, the number of the first locking portions 121 can be one or multiple. Exemplarily, the number of the first locking portions 121 is two. Please continue to refer to the attached Figure 9 and the attached Figure 10 , the locking plate 122 further includes a notch 125. Wherein, the notch 125 penetrates through the locking plate 122 along the thickness direction of the locking plate 122, and the open end of the notch 125 faces the driving member 130. In other words, the notch 125 is a through groove that penetrates up and down and has one open end, that is, the notch 125 penetrates through one side surface of the locking plate 122 along the direction away from the rotation axis 123, so that the notch 125 is a U-shaped structure. On the one hand, the notch 125 can provide an installation space, and part of the driving member 130 or other components can be arranged in the notch 125, which has the advantages of saving installation space and reducing the size of the self-locking mechanism 100. On the other hand, the notch 125 can also function as a weight-reducing groove, which can reduce the weight of the locking plate 122, and further reduce the weight of the self-locking mechanism 100, improving the user experience.

[0106] The notch 125 divides the locking plate 122 and its corresponding area into two parts. In this way, the number of the first locking portions 121 can be increased. For example, the number of the first locking portions 121 is two, and the two first locking portions 121 are respectively located on both sides of the notch 125. Furthermore, the connection stability between the self-locking mechanism 100 and the supporting component can be improved. For example, the connection stability between the self-locking mechanism 100 and the equipment cabinet can be improved.

[0107] It should be noted that the first locking portion 121 and the locking plate 122 can be separate parts or integral parts. When the first locking portion 121 and the locking plate 122 are integral parts, they can be integrally manufactured by injection molding or casting, which can not only reduce the preparation difficulty of the locking member 120, but also improve the structural strength of the locking member 120.

[0108] When the first locking portion 121 includes a clamping protrusion; the longitudinal cross-sectional shape of the first locking portion 121 is triangular; or, the longitudinal cross-sectional shape of the first locking portion 121 is trapezoidal; the longitudinal cross-section is perpendicular to the plate surface of the locking plate 122. With such a setting, the contact area between the first locking portion 121 and the cooperating second locking portion 300 can be increased, and the locking strength of the self-locking mechanism 100 is improved.

[0109] In a possible implementation manner, please refer to the attached Figure 12 and the attached Figure 16, the driving member 130 includes a driving plate 134 and two driving arms 135. The two driving arms 135 are connected to the driving plate 134 and are respectively located on both sides of the locking member 120. In other words, the driving arms 135 are spaced apart so that an installation space is formed between the two driving arms 135, which is conducive to installing the locking member 120 into the installation space to reduce the size of the self-locking mechanism 100 and facilitate the development of the self-locking mechanism 100 towards small-size integration.

[0110] The part of the driving plate 134 located between the adjacent driving arms 135 protrudes towards the locking member 120 to form a protruding portion 136. Among them, the installation cavity 133 is formed on the protruding portion 136 and penetrates the protruding portion 136 along the thickness direction of the protruding portion 136.

[0111] The end of each driving arm 135 facing away from the driving plate 134 is bent towards the locking member 120 to form a first driving portion 131. In this embodiment, the number of the first driving portions 131 is two. Such a setting can increase the connection positions between the driving member 130 and the locking member 120, which is more conducive to the stability of the locking member 120 during the conversion between the first state and the second state.

[0112] It should be noted that the movement of the first driving portion 131 of the driving member 130 can be driven by a mechanical device. For example, a cylinder or other components can be used to drive the movement of the first driving portion 131; or the operator can manually drive the movement of the first driving portion 131.

[0113] Exemplarily, a first holding hole 137 is provided on the driving plate 134, and a second holding hole 117 is provided on the support member 110. The first holding hole 137 and the second holding hole 117 are opposite and communicated with each other; it should be understood that when the support member 110 includes a support plate 111 and a support cover 112, the number of the second holding holes 117 is two. One of the second holding holes 117 is provided on the support plate 111, and the other second holding hole 117 is provided on the support cover 112. The two second holding holes 117 are opposite and communicate with the first holding hole 137.

[0114] Please refer to the attached Figure 1 , part of the driving plate 134 is exposed in the second holding hole 117 to form a holding portion; when the holding portion is stressed, it drives the first driving portion 131 to move from the locking area to the unlocking area, so that the first locking portion 121 is in the first state. Taking the orientation shown in the attached Figure 1 and the attached Figure 3 as an example, when the operator holds the holding portion and drives the driving plate 134 to move in a direction away from the locking member 120, the first driving portion 131 can be driven to move from the locking area to the unlocking area, so that the first locking portion 121 is in the first state.

[0115] It should be noted that when the first locking portion 121 extends out of the accommodating cavity 113, it is in the unlocked state. Then, when the holding portion is stressed, the first driving portion 131 is driven to move from the locking area to the unlocking area, so that the first locking portion 121 is in the first state. For the attached Figure 1 and attached Figure 3 Taking the orientation shown as an example, when the operator holds the holding portion and drives the driving plate 134 to move in the direction towards the locking member 120, the first driving portion 131 can be driven to move from the locking area to the unlocking area, so that the first locking portion 121 is in the first state.

[0116] Please refer to the attached Figure 17 , the embodiment of the present application further provides a liquid-cooled switch. The liquid-cooled switch is used to dissipate heat from a server or other devices in a data center. Therefore, the liquid-cooled switch needs to be installed on the cabinet body of the equipment cabinet.

[0117] Wherein, the liquid-cooled switch includes a casing 200 and the self-locking mechanism 100 provided in any of the above embodiments. The self-locking mechanism 100 is arranged on the casing 200, and the rapid disassembly or installation between the liquid-cooled switch and the equipment cabinet can be realized through the self-locking mechanism 100. Among them, the structure and principle of the self-locking mechanism 100 can refer to the description of any of the above embodiments, and will not be elaborated herein in this embodiment.

[0118] It should be noted that the number of the self-locking mechanisms 100 in this embodiment can be one or more. Exemplarily, the number of the self-locking mechanisms 100 is two, and the shape of the casing 200 of the liquid-cooled switch is square. Then, the two self-locking mechanisms 100 can be located on both sides of the casing 200 in the width direction. Such a setting can improve the stability between the liquid-cooled switch and the casing of the equipment cabinet.

[0119] The embodiment of the present application further provides an equipment cabinet, including a cabinet body and the liquid-cooled switch described in the above embodiment. The liquid-cooled switch is installed on the cabinet body through the self-locking mechanism. Exemplarily, a second locking portion 300 is arranged on the cabinet body. The second locking portion 300 cooperates with the first locking portion 121 to realize the relative fixation or relative separation between the liquid-cooled switch and the cabinet body.

[0120] Since the liquid-cooled switch includes the self-locking mechanism described in the first aspect, the equipment cabinet of the embodiment of the present application also has the effects of the self-locking mechanism in the first aspect, which will not be elaborated herein.
