Locking structure and vacuum cleaner

Abstract

The present invention provides a locking structure and a vacuum cleaner applying the locking structure. Compared with the prior art, the lock catch in the locking structure can move as a whole, thereby increasing the application scope and functions of the vacuum cleaner. The sliding and rotation of the lock catch in the locking structure are two independent processes, so there will be no movement interference, avoiding the situation that the lock catch cannot extend into the lock hole. The entire unlocking or locking action can be completed with a simple pushing action, and the operation is simple and convenient.

Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly to a locking structure and a vacuum cleaner. Background Art

[0002] A vacuum cleaner is a sanitary appliance used to remove dust from floors, carpets, walls, furniture, clothes, and various crevices. The motor in the vacuum cleaner body drives the impeller of the blower to rotate at a high speed, exhausting the air inside the vacuum cleaner, creating an instantaneous vacuum inside the vacuum cleaner, and forming a relatively high negative pressure difference with the outside atmosphere. Under the action of this negative pressure difference, dust and other foreign substances near the suction head or brush head, together with the air, are sucked into the cyclone separation part inside the machine body through the air inlet. After the dust and other foreign substances are separated by the cyclone, they enter the dust collection cylinder through the dust outlet for separate cleaning later; while the clean air after dust removal is discharged from the air outlet, passes through the connected suction motor, and is finally discharged outside the vacuum cleaner body.

[0003] Vacuum cleaners usually have some detachable components, such as a dust cup. The prior art uses a snap structure to achieve the disassembly, assembly, and fixation of detachable components. However, the existing snap structure can only switch between two states of unlocking and locking, and the lock buckle as a whole does not have a moving function, and its application scenarios are relatively limited, making the vacuum cleaner inconvenient to use. Summary of the Invention

Detailed implementation mode

[0061] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0062] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. The "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling). In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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 to the present invention.

[0063] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

[0064] The present invention provides a locking structure. Through structural design, the locking structure can be switched between an unlocked state and a locked state and can be maintained fixed in one of the states. At the same time, the locking buckle used for locking in the locking structure can move as a whole, improving the application scenarios and the convenience of use of the locking buckle.

[0065] Specifically, as Figure 1 and Figure 9a shown, the locking structure 10 includes: a base 100, a first slider 200, a second slider 300, a third slider 400, a connecting portion 600, and a locking buckle 500.

[0066] As Figure 2 shown, the base 100 is provided with a first chute. The first chute is a semi-through chute, and the first chute has opposite first side surfaces 101 and second side surfaces 102, as well as opposite openings and a third side surface 103;

[0067] As Figure 3 and Figure 4 shown, the first slider 200 can slide laterally relative to the base 100 and has a first position close to the second side surface 102 and a second position close to the first side surface 101;

[0068] As Figure 5 shown, the second slider 300 can slide longitudinally relative to the base 100 and has a third position close to the third side surface 103 and a fourth position close to the opening;

[0069] As Figure 6 shown, the third slider 400 can slide longitudinally relative to the base 100 and has a fifth position close to the third side surface 103, a seventh position close to the opening, and a sixth position located between the fifth position and the seventh position;

[0070] As Figure 8 shown, the connecting portion 600 slides synchronously with the second slider 300 and has an eighth position close to the second side surface 102 and a ninth position close to the first side surface 101;

[0071] As Figure 7As shown, the latch 500 includes two latch arms 510. Both of the two latch arms 510 are rotatably connected to the second slider 300 and slide synchronously with the second slider 300. The latch 500 includes an unlocked state in which the two latch arms 510 are close to each other and a locked state in which the two latch arms 510 are far from each other. When the latch 500 is in the locked state, it extends into the lock hole 911 in the external device and forms a lock.

[0072] As Figures 9a to 9f shown, when the first slider 200 is in the first position, it restricts the connecting portion 600 from sliding from the eighth position to the ninth position. When the second slider 300 is in the third position, it restricts the first slider 200 from sliding from the first position to the second position. When the third slider 400 is in the fifth position or the sixth position, it restricts the latch 500 from moving from the unlocked state to the locked state. When the connecting portion 600 is in the eighth position, the second slider 300 and the third slider 400 slide synchronously.

[0073] The entire locking structure 10 has an unlocking position, an intermediate position, and a locking position:

[0074] As Figure 9a and Figure 9b shown, when in the unlocking position, the first slider 200 is in the first position, the second slider 300 is in the third position, the third slider 400 is in the fifth position, the connecting portion 600 is in the eighth position, and the latch 500 is in the unlocked state. At this time, since the second slider 300 is in the third position close to the third side surface 103, the latch 500 connected to the second slider 300 is also relatively close to the third side surface 103 and does not extend out of the base 100.

[0075] As Figure 9c and Figure 9d shown, when in the intermediate position, the first slider 200 is in the second position, the second slider 300 is in the fourth position, the third slider 400 is in the sixth position, the connecting portion 600 is in the ninth position, and the latch 500 is in the unlocked state. At this time, since the second slider 300 is in the fourth position close to the opening, the latch 500 connected to the second slider 300 extends out of the base 100 and can extend into the lock hole 911 on other devices.

[0076] As Figure 9e shown, when in the locking position, the first slider 200 is in the second position, the second slider 300 is in the fourth position, the third slider 400 is in the seventh position, the connecting portion 600 is in the ninth position, and the latch 500 is in the locked state.

[0077] The process of the locking structure 10 moving from the unlocking position to the intermediate position is the first locking process, the process of moving from the intermediate position to the locking position is the second locking process, the process of moving from the locking position to the intermediate position is the first unlocking process, and the process of moving from the intermediate position to the unlocking position is the second unlocking process.

[0078] In short, during the entire locking and unlocking processes, the function of the first slider 200 is to control the position of the connecting portion 600 through position adjustment; the function of the connecting portion 600 is to enable the second slider 300 and the third slider 400 to slide synchronously or independently through position adjustment; the function of the second slider 300 is to drive the lock catch 500 to slide; the function of the third slider 400 is to drive the second slider 300 to slide and adjust the position of the first slider 200; the function of the lock catch 500 is to engage with the lock hole 911. Among them, the third slider 400 is the prime mover, driven by an external force, and other components are directly or indirectly driven by the third slider 400.

[0079] Please refer to Figures 9a to 9f , Figure 10a and Figure 10b and also Figures 11a to 11e understand the following movement process:

[0080] Explanation of the sliding process of the first slider 200:

[0081] In one of the embodiments, as Figures 11a to 11d shown, the first slider 200 controls its own position through a combined surface structure. Specifically, the first slider 200 is provided with a combined surface, including a first stepped surface 201 and a second stepped surface 202 that are parallel to the first side surface 101 and non-coplanar. The first stepped surface 201 is closer to the third side surface 103 than the second stepped surface 202, and the second stepped surface 202 is closer to the second side surface 102 than the first stepped surface 201; when the second slider 300 abuts against the first stepped surface 201, the first slider 200 is in the first position; when the second slider 300 abuts against the second stepped surface 202, the first slider 200 is in the second position. Since the second slider 300 only slides longitudinally and does not slide laterally, when the second slider 300 slides to different positions longitudinally, and the first stepped surface 201 and the second stepped surface 202, which have a distance in the lateral direction, respectively abut against the second slider 300, the first slider 200 will also have a distance in the lateral direction.

[0082] Further, the sliding of the first slider 200 from the first position to the second position is driven by the first elastic member 710. A first elastic member 710 is disposed between the first slider 200 and the base 100, and the first elastic member 710 causes the first slider 200 to slide toward the first side surface 101 or have a tendency to slide toward the first side surface 101. When the second slider 300 is in the third position, it abuts against the first step surface 201. Since the second slider 300 cannot slide laterally, the elastic force of the first elastic member 710 cannot drive the first slider 200. When the second slider 300 moves from the third position to the fourth position, the second slider 300 disengages from the first step surface 201 and has a certain distance from the second step surface 202. At this time, the elastic force of the first elastic member 710 drives the first slider 200 to move from the first position to the second position.

[0083] Further, the sliding of the first slider 200 from the second position to the first position is driven by the third slider 400. A connecting inclined surface 203 is further disposed on the combined surface of the first slider 200. The connecting inclined surface 203 is connected to and inclined with respect to the first step surface 201 and the second step surface 202; correspondingly, a first protrusion 410 is disposed on the third slider 400. During the process of the third slider 400 sliding from the seventh position to the sixth position, the first protrusion 410 pushes against the connecting inclined surface 203, causing the first slider 200 to slide from the second position to the first position. In other words, during the first unlocking process, when the third slider 400 slides longitudinally, the first protrusion 410 thereon can push against the connecting inclined surface 203, causing the first slider 200 to perform a lateral movement and slide from the second position to the first position.

[0084] In addition, in order to ensure that the first slider 200 only performs lateral sliding and does not perform longitudinal sliding, a first positioning portion 110 is disposed on the base 100. The first slider 200 always abuts against the first positioning portion 110, and the first positioning portion 110 is used to limit the longitudinal sliding of the first slider 200. The first positioning portion 110 abuts against a side surface of the first slider 200 parallel to the lateral direction, and the third side surface 103 abuts against another side surface of the first slider 200 parallel to the lateral direction, so that the first slider 200 does not perform longitudinal sliding.

[0085] Explanation of the movement of the second slider 300:

[0086] In some of the embodiments, such as Figures 9a to 9f , and Figure 10a and Figure 10bAs shown, the sliding of the second slider 300 from the third position to the fourth position is driven by the third slider 400. A first protruding portion 410 is provided on the third slider 400. When the connecting portion 600 is in the eighth position, the connecting portion 600 abuts against the first protruding portion 410 and forms a stop. Since the connecting portion 600 and the second slider 300 slide synchronously, the connecting portion 600 and the third slider 400 slide synchronously. When the third slider 400 moves from the fifth position to the sixth position, the second slider 300 can be driven to move from the third position to the fourth position. When the connecting portion 600 is in the ninth position, the connecting portion 600 and the first protruding portion 410 are disengaged from abutting. During the process of the third slider 400 sliding from the sixth position to the seventh position, the second slider 300 is no longer driven to slide.

[0087] It should be noted that the first protruding portion 410 in the foregoing has two functions. One is to push the connecting inclined surface 203 to make the first slider 200 slide, and the other is to push the connecting portion 600 to make the connecting portion 600 slide. These two functions are respectively realized by the two ends of the first protruding portion 410. The realization of these two functions by one first protruding portion 410 is for the consideration of simplifying the structure. These two functions can also be realized by two relatively independently provided protruding structures.

[0088] In some of the embodiments, the sliding of the second slider 300 from the fourth position to the third position is driven by the third slider 400. A second protruding portion 420 is provided on the third slider 400. When the third slider 400 is in the sixth position, the fifth position, and between these two positions, the second protruding portion 420 abuts against the second slider 300, so that the third slider 400 and the second slider 300 slide synchronously toward the third side surface 103. In other words, when the third slider 400 moves from the sixth position to the fifth position, the second protruding portion 420 pushes the second slider 300 to slide from the fourth position to the third position.

[0089] Furthermore, in order to ensure that the locking device will not become loose in the unlocked position, a connecting plane 204 is provided on the combined surface of the first slider 200. The connecting plane 204 is connected to and perpendicular to the first step surface 201 and the second step surface 202. When the second slider 300 is in the fourth position, the second slider 300 abuts against the connecting plane 204. Since the first slider 200 only slides horizontally and does not slide longitudinally, the connecting plane 204 parallel to the third side surface 103 will not slide longitudinally either. Therefore, when the second slider 300 abuts against the connecting plane 204, it cannot slide longitudinally, and it can be ensured that the lock catch 500 is always in a state of protruding from the base 100.

[0090] In addition, to ensure that the second slider 300 does not slide laterally, the two sides of the second slider 300 parallel to the longitudinal direction: surface 304 and surface 305 are respectively always in contact with the first side 101 and the second side 102, ensuring that the second slider 300 does not slide laterally. To ensure that the third slider 400 does not slide laterally, the two sides of the third slider 400 parallel to the longitudinal direction: surface 402 and surface 403 are respectively always in contact with the first side 101 and the second side 102, ensuring that the second slider 300 does not slide laterally.

[0091] Explanation of the movement of the third slider 400:

[0092] The third slider 400 is completely driven by an external force and serves as the prime mover of the entire locking structure 10. To facilitate the user to push the third slider 400, a push button 921 is provided on the third slider 400, and the push button 921 protrudes from the entire locking structure 10.

[0093] Explanation of the movement of the connecting portion 600:

[0094] In some of the embodiments, such as Figure 11c and Figure 11d and Figure 9f as shown, the movement of the connecting portion 600 from the eighth position to the ninth position is driven by the second elastic member 720. A second elastic member 720 is provided between the second slider 300 and the connecting portion 600, and the elastic force of the second elastic member 720 causes the connecting portion 600 to move away from the second slider 300 or tend to move away from the second slider 300. A second chute 210 is provided on the first slider 200, and the chute penetrates longitudinally. One end of the connecting portion 600 abuts against the pushing surface 205 parallel to the longitudinal direction on the second chute 210, and the other end is connected to the second slider 300 through the second elastic member 720. When the first slider 200 moves from the first position to the second position, the pushing surface 205 slides toward the first side 101, and the connecting portion 600 always abuts against the pushing surface 205 under the action of the second elastic member 720, which is equivalent to the connecting portion 600 sliding toward the first side 101, that is, the connecting portion 600 slides from the eighth position to the ninth position.

[0095] Furthermore, the movement of the connecting portion 600 from the ninth position to the eighth position is driven by the first slider 200. When the first slider 200 moves from the second position to the first position, the pushing surface 205 slides toward the second side 102, and the connecting portion 600 always abuts against the pushing surface 205 under the action of the second elastic member 720, which is equivalent to the connecting portion 600 sliding toward the second side 102, that is, the connecting portion 600 slides from the ninth position to the eighth position. During this process, the second elastic member 720 stores energy and is used to drive the connecting portion 600 to slide from the eighth position to the ninth position during the next action.

[0096] In addition, in order to ensure that the connecting portion 600 can slide synchronously with the second slider 300, a second installation groove 310 is provided on the second slider 300, and the connecting portion 600 and the second elastic member 720 are arranged in the second installation groove 310. The surface 603 of the connecting portion 600 abuts against the side surface of the second installation groove 310, and when the connecting portion 600 slides, it can drive the second slider 300 to slide.

[0097] Explanation of the movement of the lock 500:

[0098] In one of the embodiments, as Figures 11a to 11e shown, the sliding of the lock 500 is driven by the second slider 300. A first mounting hole 511 is provided on each lock arm 510. Correspondingly, two cylindrical protrusions 320 are provided on the second slider 300, and the lock arm 510 is sleeved in the cylindrical protrusion 320 through the first mounting hole 511. In this way, the second slider 300 and the lock 500 can achieve synchronous sliding.

[0099] In one of the embodiments, the rotation of the lock 500 is driven by the third slider 400. Two opposite third protrusions 430 are provided on the third slider 400, and a first inclined surface 401 is provided on each third protrusion 430. A second inclined surface 503b and a third inclined surface 503a that match the first inclined surface 401 are provided on the lock arm 510; when the third slider 400 is in the fifth position and the sixth position, the first inclined surface 401 abuts against the second inclined surface 503b, and the lock 500 is in the unlocked state; when the third slider 400 is in the seventh position, the first inclined surface 401 abuts against the third inclined surface 503a, and the lock 500 is in the locked state. A third elastic member 730 is further provided between the two lock arms 510, and the elastic force of the third elastic member 730 causes the two lock arms 510 to move away from each other or tend to move away from each other. When the third slider 400 slides from the sixth position to the seventh position, the first inclined surface 401 has a tendency to disengage from the second inclined surface 503b or the third inclined surface 503a, and the two lock arms 510 move away from each other under the action of the third elastic member 730, so that the second inclined surface 503b or the third inclined surface 503a always abuts against the first inclined surface 401. When the third slider 400 slides from the seventh position to the sixth position, the first inclined surface 401 pushes against the second inclined surface 503b or the third inclined surface 503a, and the two lock arms 510 move closer to each other under the push of the third slider 400. At this time, the third elastic member 730 stores energy for driving the two lock arms 510 to move away from each other during the next action.

[0100] It should be noted that the second inclined surface 503b and the third inclined surface 503a are only divided in terms of area, and they can be a continuous inclined surface or two discontinuous inclined surfaces.

[0101] The present invention also provides a vacuum cleaner 900, as Figures 12a to 12dAs shown in the figure, it includes a first part 910, a second part 920, and the locking structure 10 provided in any one of the above embodiments. A locking hole 911 is provided on the first part 910, and a receiving groove is provided on the second part 920. The locking structure 10 is arranged in the receiving groove. After the locking buckle 500 in the locking structure 10 extends into the locking hole 911 and is in the locked state, the connection between the first part 910 and the second part 920 is completed. Wherein, the first part 910 or the second part 920 can be components such as a dust collection cup and a power supply component that need to be frequently disassembled. With the locking structure 10, locking and unlocking can be conveniently completed.

[0102] Since the locking buckle 500 in the locking structure 10 can move as a whole, the application range of the vacuum cleaner 900 can be improved. For example, a thin sheet-like filtering structure is added at the connection between the first part 910 and the second part 920. When the locking structure 10 is in the unlocked position, the locking buckle 500 retracts into the locking structure 10, and the filtering structure can be taken out from the connection between the first part 910 and the second part 920. However, the existing buckles cannot move, which hinders the removal of the filtering structure.

[0103] In summary, the locking structure 10 provided by the present invention and the vacuum cleaner 900 applying the locking structure 10 at least have the following advantages:

[0104] First, the locking buckle 500 can move as a whole, thereby increasing the application range and functions of the vacuum cleaner 900.

[0105] Second, the sliding and rotation of the locking buckle 500 in the locking structure 10 are two independent processes, so there will be no movement interference, and it is avoided that the locking buckle 500 cannot extend into the locking hole 911.

[0106] Third, the entire unlocking or locking action can be completed with a simple pushing action, and the operation is simple and convenient.

[0107] Embodiment 1:

[0108] This embodiment provides a locking structure 10, as Figures 1 to 9a shown, including a base 100, a first slider 200, a second slider 300, a third slider 400, a connecting part 600, and a locking buckle 500:

[0109] As Figure 2As shown in the figure, a first chute is provided on the base 100. The first chute is a semi-through chute. The first chute has opposite first side surface 101 and second side surface 102, and also has an opening and a third side surface 103 corresponding to the opening. The first slider 200 always abuts against the third side surface 103, and the second slider 300 and the third slider 400 always abut against the first side surface 101 and the second side surface 102. A first positioning portion 110 and a second positioning portion 120 are further provided on the base 100. The second positioning portion 120 and the third side surface 103 determine the sliding range of the second slider 300, and the first positioning portion 120 and the third side surface 103 restrict the first slider 200 from sliding longitudinally.

[0110] As Figure 3 and Figure 4 shown in the figure, a second groove, a first clamping groove 230 and a first installation groove 220 are provided on the first slider 200. The second groove is a through groove and runs through longitudinally. One side surface of the second groove is formed by a combination of multiple surfaces, including a first step surface 201, a second step surface 202, a connecting inclined surface 203 and a connecting flat surface 204. Among them, the first step surface 201 and the second step surface 202 are both parallel to the second side surface 102. The connecting inclined surface 203 connects the first step surface 201 and the second step surface 202 and is inclined to the first step surface 201. The connecting flat surface 204 connects the first step surface 201 and the second step surface 202 and is perpendicular to the first step surface 201. In addition to this combined surface, the second groove also has a pushing surface 205 and a surface 206. The second slider 300 is arranged in the second groove and can slide longitudinally along the second groove. The first clamping groove 230 is used to cooperate with the second positioning portion 120. The first installation groove 220 is used to install the first elastic member 710. The first elastic member 710 connects the bottom surface of the first installation groove 220 and the second side surface 102 on the base 100.

[0111] As Figure 5 shown in the figure, a second installation groove 310 and a cylindrical protruding portion 320 are provided on the second slider 300. The second installation groove 310 is used to accommodate the connecting portion 600 and the second elastic member 720. The second elastic member 720 connects the bottom surface of the second installation groove 310 and the connecting portion 600.

[0112] As Figure 6 shown in the figure, a first protruding portion 410, a second protruding portion 420 and a third protruding portion 430 are provided on the third slider 400. The three protruding portions all protrude from the side of the third slider 400 facing the base 100. The third protruding portion 430 is divided into two relatively independent parts, and a first inclined surface 401 is provided on each part.

[0113] As Figure 7 shown in the figure, the latch 500 includes two locking arms 510. Each locking arm 510 has a first installation hole 511, a locking end 512 and a surface 503.

[0114] As Figures 9a to 9f , and Figures 11a to 11e shown, when the locking structure 10 is in the unlocked position, the first engaging groove 230 on the first slider 200 engages with the first positioning portion 110, the surface 208 abuts against the first positioning portion 110, the surface 206 abuts against the third side surface 103, restricting the longitudinal movement of the first slider 200; the surface 207 abuts against the first positioning portion 110, the first stepped surface 201 abuts against the surface 301, and at the same time the surface 302 abuts against the first side surface 101, restricting the lateral movement of the first slider 200. The surface 301 on the second slider 300 abuts against the first stepped surface 201, and the surface 302 abuts against the first side surface 101, restricting the lateral movement of the second slider 300. The second protrusion 420 on the third slider 400 abuts against the surface 306 on the second slider 300, and the first protrusion 410 and the surface 303 maintain a certain distance. The connecting portion 600 is completely located in the second installation groove 310, and the surface 601 abuts against the pushing surface 205. The first inclined surface 401 on the third slider 400 abuts against the surface 503, causing the two locking arms 510 to approach. The locking arms 510 are provided with a first mounting hole 511 and a locking end 512, and the first mounting hole 511 is sleeved on the cylindrical protrusion 320 on the second slider 300.

[0115] The first elastic member 710 is in a compressed state, causing the first slider 200 to tend to move towards the first side surface 101; the second elastic member 720 is in a compressed state, causing the connecting portion 600 to tend to move towards the first side surface 101; the third elastic member 730 is in a compressed state, causing the two locking arms 510 to tend to move away from each other.

[0116] The first locking process: During the process of the locking structure 10 moving from the unlocking position to the intermediate position, first, it pushes the third slider 400 to slide towards the opening. The first protruding portion 410 abuts against the surface 602, driving the connecting portion 600 to slide. The surface 603 on the connecting portion 600 pushes against the side surface of the second mounting groove 310, driving the second slider 300 to slide. When the locking structure 10 moves to the intermediate position, the surface 306 abuts against the second protruding portion 420, and the second slider 300 stops moving. The surface 301 on the second slider 300 disengages from the first stepped surface 201 on the first slider 200. The first slider 200 slides towards the first side surface 101 under the action of the first elastic member 710, pushing the surface 205 to slide towards the first side surface 101. Under the action of the second elastic member 720, the surface 601 on the connecting portion 600 always abuts against the pushing surface 205, that is, the connecting portion 600 also slides towards the first side surface 101. At the same time, the surface 301 on the second slider 300 abuts against the connecting plane 204. The first slider 200 stops moving. Due to the lateral sliding of the connecting portion 600, the surface 602 disengages from the first protruding portion 410, and the third slider 400 no longer drives the connecting portion 600 and the second slider 300 to slide longitudinally. During this process, since the second slider 300 and the third slider 400 move synchronously, there is no relative sliding between the locking arm 510 and the third slider 400, and the first inclined surface 401 always abuts against the second inclined surface 503b. Therefore, the locking arm 510 only slides longitudinally.

[0117] The second locking process: During the process of the locking structure 10 moving from the intermediate position to the locking position, since the connecting portion 600 is no longer in contact with the first protruding portion 410, the connecting portion 600 remains stationary. Therefore, the second slider 300 and the first slider 200 also remain stationary. The third slider 400 continues to slide towards the opening direction. The first inclined surface 401 has a tendency to disengage from abutting against the surface 503. The two locking arms 510 open under the action of the third elastic member 730, so that the surface 503 always abuts against the first inclined surface 401. When the first inclined surface 401 abuts against the third inclined surface 503a, the locking structure 10 is in the unlocking position, and the locking end 512 on the locking arm 510 is clamped in the lock hole 911 on the external device to complete the locking.

[0118] The first unlocking process: During the process of the locking structure 10 moving from the locked position to the intermediate position, the movement between the locking arm 510 and the third slider 400 is opposite to that of the second unlocking process, which will not be elaborated here. When the third slider 400 moves close to the sixth position, the first protrusion 410 thereon abuts against the connecting inclined surface 203 on the first slider 200, and drives the first slider 200 to slide laterally from the second position to the first position through this abutment. During the sliding process of the first slider 200, the connecting part 600 is driven to slide, so that the projections of the connecting part 600 and the first protrusion 410 coincide in the longitudinal direction. However, since the first protrusion 410 is closer to the third side surface 103 than the connecting part 600 at this time, the connecting part 600 does not hinder the sliding of the third slider 400. When the locking structure 10 is in the intermediate position, the third slider 400 moves to the first position, the connecting plane 204 no longer hinders the second slider 300 from sliding to the third position, and at the same time, the second protrusion 420 on the third slider 400 abuts against the second slider 300.

[0119] The second unlocking process: During the process of the locking structure 10 moving from the intermediate position to the unlocking position, the third slider 400 pushes the surface 306 on the second slider 300 through the second protrusion 420, driving the second slider 300 to slide to the third position to complete the unlocking.

[0120] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0121] The above-described embodiments merely represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
