In short, throughout the locking and unlocking processes, the first slider 200 functions to control the position of the connecting portion 600 by position adjustment; the connecting part 600 functions to allow the second slider 300 and the third slider 400 to slide synchronously or independently from each other through adjustment of the position; the second slider 300 is used for driving the lock catch 500 to slide; the third slide block 400 is used for driving the second slide block 300 to slide and adjusting the position of the first slide block 200; the lock catch 500 is used for clamping the lock hole 911. The third slider 400 is a driving element and is driven by external force, and other parts are directly or indirectly driven by the third slider 400.

Referring to fig. 9a to 9f, fig. 10a and 10b, and fig. 11a to 11e, the following movement processes are understood:

description of the sliding process of the first slider 200:

in one embodiment, as shown in fig. 11a to 11d, the first slider 200 controls the position of the first slider 200 by a combined surface structure. Specifically, the first slider 200 is provided with a combination surface, which includes a first step surface 201 and a second step surface 202 that are parallel to the first side surface 101 and are not coplanar, the first step surface 201 is close to the third side surface 103 relative to the second step surface 202, and the second step surface 202 is close to the second side surface 102 relative to the first step surface 201; when the second slider 300 abuts against the first step surface 201, the first slider 200 is at the first position; when the second slider 300 abuts against the second step surface 202, the first slider 200 is in the second position. Since the second slider 300 slides only in the longitudinal direction and does not slide in the lateral direction, when the second slider 300 slides in the longitudinal direction to different positions and the first step surface 201 and the second step surface 202 spaced apart in the lateral direction are respectively abutted against the second slider 300, the first slider 200 also generates a distance in the lateral direction.

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 makes the first slider 200 slide toward the first side 101 or has a tendency to slide toward the first side 101. When the second slider 300 is at the third position, it abuts against the first step surface 201, and the first slider 200 cannot be driven by the elastic force of the first elastic member 710 because the second slider 300 cannot slide laterally. When the second slider 300 moves from the third position to the fourth position, the second slider 300 is separated from the first step surface 201 and is spaced apart from the second step surface 202, and the elastic force of the first elastic member 710 drives the first slider 200 to move from the first position to the second position.

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 arranged on the combined surface of the first slider 200, and the connecting inclined surface 203 is connected with and inclined to the first step surface 201 and the second step surface 202; correspondingly, the third slider 400 is provided with a first protrusion 410, and when the third slider 400 slides from the seventh position to the sixth position, the first protrusion 410 pushes the connection slope 203, so that the first slider 200 slides from the second position to the first position. In other words, during the first unlocking process, when the third slider 400 slides in the longitudinal direction, the first protrusion 410 thereon can push the connection slope 203, so that the first slider 200 moves in the transverse direction and slides from the second position to the first position.

In order to ensure that the first slider 200 slides only in the lateral direction and does not slide in the longitudinal direction, the base 100 is provided with a first positioning portion 110, the first slider 200 always abuts against the first positioning portion 110, and the first positioning portion 110 restricts the longitudinal sliding of the first slider 200. The first positioning portion 110 abuts against one side surface of the first slider 200 parallel to the lateral direction, and the third side surface 103 abuts against the other side surface of the first slider 200 parallel to the lateral direction, so that the first slider 200 does not slide longitudinally.

Description of the movement of the second slider 300:

in some of the embodiments, as shown in fig. 9a to 9f, and fig. 10a and 10b, the sliding of the second slider 300 from the third position to the fourth position is driven by the third slider 400. The third slider 400 is provided with a first protrusion 410, and when the connecting portion 600 is located at the eighth position, the connecting portion 600 abuts against the first protrusion 410 and forms a stop, so that the connecting portion 600 and the third slider 400 slide synchronously due to the synchronous sliding of the connecting portion 600 and the second slider 300. When the third slider 400 moves from the fifth position to the sixth position, it can drive the second slider 300 to move from the third position to the fourth position. When the connecting portion 600 is located at the ninth position, the connecting portion 600 and the first protruding portion 410 are separated from each other, and the third slider 400 does not drive the second slider 300 to slide in the process of sliding from the sixth position to the seventh position.

It should be noted that, the first protrusion 410 in the foregoing has two functions, one is to push the connection inclined surface 203 to enable the first slider 200 to slide, and the other is to push the connection portion 600 to enable the connection portion 600 to slide, the two functions are respectively realized by two ends of the first protrusion 410, and the two functions are realized by one first protrusion 410 in view of simplifying the structure, and the two functions can also be realized by two protrusion structures which are relatively independently arranged.

In some embodiments, the sliding of the second slider 300 from the fourth position to the third position is driven by the third slider 400. The third slider 400 is provided with a second protrusion 420, and when the third slider 400 is located at the sixth position, the fifth position, or between the sixth position and the fifth position, the second protrusion 420 abuts against the second slider 300, so that the third slider 400 and the second slider 300 slide to the third side surface 103 synchronously. In other words, when the third slider 400 moves from the sixth position to the fifth position, the second protrusion 420 pushes the second slider 300 to slide from the fourth position to the third position.

Further, in order to ensure that the locking device does not loosen in the unlocked position, a connecting plane 204 is provided on the combining surface of the first slider 200, the connecting plane 204 is connected and perpendicular to the first step surface 201 and the second step surface 202, and 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 slides only in the lateral direction without sliding in the longitudinal direction, the connecting plane 204 parallel to the third side 103 does not slide in the longitudinal direction, and therefore, when the second slider 300 abuts against the connecting plane 204, the longitudinal sliding cannot be performed, and the latch 500 can be ensured to be always protruded from the base 100.

Further, in order to ensure that the second slider 300 does not slide laterally, the second slider 300 is parallel to both side surfaces of the longitudinal direction: the surfaces 304 and 305 always abut against the first side surface 101 and the second side surface 102, respectively, so that the second slider 300 cannot slide laterally. To ensure that the third slider 400 does not slide laterally, the third slider 400 is parallel to both sides of the longitudinal direction: the surfaces 402 and 403 are always in contact with the first side surface 101 and the second side surface 102, respectively, to ensure that the second slider 300 does not slide laterally.

Description of movement of the third slider 400:

the third slider 400 is completely driven by an external force and serves as a prime mover of the entire locking structure 10. In order to facilitate the user to push the third slider 400, a push button 921 is disposed on the third slider 400, and the push button 921 protrudes from the entire locking structure 10.

Description of movement of the connection portion 600:

in some embodiments, as shown in fig. 11c and 11d, and fig. 9f, the movement of the connection portion 600 from the eighth position to the ninth position is driven by the second elastic member 720. A second elastic member 720 is disposed between the second slider 300 and the connecting portion 600, and the elastic force of the second elastic member 720 makes the connecting portion 600 move away from the second slider 300 or have a tendency to move away from the second slider 300. The first sliding block 200 is provided with a second sliding slot 210, the sliding slot is through along the longitudinal direction, one end of the connecting portion 600 abuts against the pushing surface 205 parallel to the longitudinal direction on the second sliding slot 210, and the other end is connected to the second sliding block 300 through a second elastic member 720. When the first slider 200 moves from the first position to the second position, the pushing surface 205 slides towards the first side surface 101, the connecting portion 600 is always abutted against the pushing surface 205 under the action of the second elastic member 720, which is equivalent to that the connecting portion 600 slides towards the first side surface 101, i.e. the connecting portion 600 slides from the eighth position to the ninth position.

Further, 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 towards the second side surface 102, the connecting portion 600 is always abutted against the pushing surface 205 under the action of the second elastic member 720, which is equivalent to the connecting portion 600 sliding towards the second side surface 102, that is, the connecting portion 600 slides from the ninth position to the eighth position. In the process, the second elastic member 720 stores energy and is used for driving the connecting portion 600 to slide from the eighth position to the ninth position in the next action.

In addition, in order to ensure that the connection part 600 can slide in synchronization with the second slider 300, a second mounting groove 310 is provided on the second slider 300, and the connection part 600 and the second elastic member 720 are disposed in the second mounting groove 310. The surface 603 of the connecting portion 600 abuts against the side surface of the second mounting groove 310, and the connecting portion 600 can drive the second slider 300 to slide when sliding.

Description of movement of the shackle 500:

in one embodiment, as shown in fig. 11a to 11e, the sliding of the lock catch 500 is driven by the second slider 300. Each locking arm 510 is provided with a first mounting hole 511, correspondingly, the second slider 300 is provided with two cylindrical protrusions 320, and the locking arm 510 is sleeved in the cylindrical protrusions 320 through the first mounting hole 511. Thus, the second slider 300 and the latch 500 can slide synchronously.

In one embodiment, the rotation of the latch 500 is driven by the third slider 400. The third slider 400 is provided with two opposite third protrusions 430, each third protrusion 430 is provided with a first inclined surface 401, and the locking arm 510 is provided with a second inclined surface 503b and a third inclined surface 503a which are matched with the first inclined surface 401; when the third slider 400 is located at the fifth position and the sixth position, the first inclined surface 401 abuts against the second inclined surface 503b, and the latch 500 is in the unlocked state; when the third slider 400 is at the seventh position, the first inclined surface 401 abuts against the third inclined surface 503a, and the latch 500 is in the locked state. A third elastic member 730 is disposed between the two locking arms 510, and the elastic force of the third elastic member 730 makes the two locking arms 510 move away from each other or have a tendency 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 tends to disengage from the second inclined surface 503b or the third inclined surface 503a, and the two locking arms 510 are separated from each other by the third elastic member 730, so that the second inclined surface 503b or the third inclined surface 503a is always abutted 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 the second inclined surface 503b or the third inclined surface 503a, the two locking arms 510 approach each other under the pushing of the third slider 400, and the third elastic member 730 stores energy for driving the two locking arms 510 to move away from each other in the next action.

It should be noted that the second inclined surface 503b and the third inclined surface 503a are only divided into areas, and both of them may be a continuous inclined surface or two discontinuous inclined surfaces.

The utility model also provides a vacuum cleaner 900, as shown in fig. 12a to 12d, comprising a first part 910, a second part 920 and a locking structure 10 provided in any one of the above embodiments, wherein the first part 910 is provided with a lock hole 911, the second part 920 is provided with a containing groove, and the locking structure 10 is arranged in the containing groove; after the lock catch 500 in the locking structure 10 extends into the lock hole 911 and is in the locked state, the connection between the first portion 910 and the second portion 920 is completed. The first portion 910 or the second portion 920 may be a dust cup, a power supply assembly, or other parts that need to be frequently disassembled, and the locking and unlocking can be conveniently performed by using the locking structure 10.

Since the lock catch 500 in the locking structure 10 can move integrally, the range of application of the cleaner 900 can be increased. For example, a sheet-like filter structure is added at the joint of the first portion 910 and the second portion 920, and when the locking structure 10 is in the unlocking position, the lock catch 500 is retracted in the locking structure 10, and the filter structure can be taken out from the joint of the first portion 910 and the second portion 920. The existing buckle can not move, so that the filter structure is prevented from being taken out.

To sum up, the utility model provides a locking structure 10 and the dust catcher 900 of having applied this locking structure 10 possess following advantage at least:

first, the catch 500 is capable of moving as a unit, thereby increasing the range of applications and functions of the cleaner 900.

Secondly, the sliding and the rotation of the lock catch 500 in the locking structure 10 are divided into two independent processes, so that the movement interference cannot occur, and the lock catch 500 is prevented from not extending into the lock hole 911.

And thirdly, the whole unlocking action or locking action can be completed only by simple pushing action, and the operation is simple and convenient.

The first embodiment is as follows:

as shown in fig. 2, the base 100 is provided with a first sliding slot, which is a semi-through slot, and the first sliding slot has a first side 101 and a second side 102 opposite to each other, and further has an opening and a third side 103 corresponding to the opening; the first slider 200 is always abutted against the third side surface 103, and both the second slider 300 and the third slider 400 are always abutted against the first side surface 101 and the second side surface 102. The base 100 is further provided with a first positioning portion 110 and a second positioning portion 120, the first positioning portion 110 and the third side 103 determine the sliding range of the second slider 300, and the second positioning portion 120 and the third side 103 limit the first slider 200 from sliding in the longitudinal direction.

As shown in fig. 3 and 4, a second groove, a first clamping groove 230 and a first mounting groove 220 are formed in the first slider 200, and the second groove is a through groove and longitudinally penetrates through the through groove; one side surface of the second recess is formed by a combination of a plurality of surfaces including a first step surface 201, a second step surface 202, a connecting inclined surface 203 and a connecting flat surface 204, wherein 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, and the second recess has a pushing surface 205 and a surface 206 in addition to the combination surface. The second slider 300 is arranged in the second groove and can slide longitudinally along the second groove; the first engaging groove 230 is used for matching with the second positioning portion 120; the first mounting groove 220 is used for mounting a first elastic member 710, and the first elastic member 710 connects the bottom surface of the first mounting groove 220 and the second side surface 102 of the base 100.

As shown in fig. 5, the second slider 300 is provided with a second mounting groove 310 and a cylindrical protrusion 320, the second mounting groove 310 is used to accommodate the connection portion 600 and a second elastic member 720, and the second elastic member 720 connects the bottom surface of the second mounting groove 310 and the connection portion 600.

As shown in fig. 6, the third slider 400 is provided with a first protrusion 410, a second protrusion 420 and a third protrusion 430, which all protrude from a side of the third slider 400 facing the base 100. The third projection 430 is divided into two relatively independent portions each of which is provided with the first slope 401.

As shown in FIG. 7, latch 500 includes two latch arms 510, each latch arm 510 having a first mounting hole 511, a locking end 512, and a face 503.

As shown in fig. 9a to 9f and fig. 11a to 11e, when the locking structure 10 is at the unlocking 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, and the surface 206 abuts against the third side surface 103, so as to limit the longitudinal movement of the first slider 200; the surface 207 abuts against the first positioning portion 110, the first step surface 201 abuts against the surface 301, and the surface 302 abuts against the first side surface 101, thereby restricting the lateral movement of the first slider 200. The surface 301 of the second slider 300 abuts against the first step surface 201, and the surface 302 abuts against the first side surface 101, thereby restricting the lateral movement of the second slider 300. The second projection 420 on the third slider 400 abuts against the face 306 on the second slider 300, the first projection 410 and the face 303 being kept at a distance. The connecting portion 600 is completely located in the second mounting groove 310, and the surface 601 abuts against the pushing surface 205. The first inclined surface 401 of the third slider 400 abuts against the surface 503 so that the two lock arms 510 approach each other. The locking arm 510 has a first mounting hole 511 and a locking end 512, and the first mounting hole 511 is disposed on the cylindrical protrusion 320 of the second slider 300.

The first elastic member 710 is in a compressed state, so that the first slider 200 has a tendency to move toward the first side 101; the second elastic member 720 is in a compressed state, so that the connection portion 600 has a tendency to move toward the first side surface 101; the third resilient member 730 is in a compressed state such that the two locking arms 510 have a tendency to move away from each other.

A first locking process: in the process that the locking structure 10 moves from the unlocking position to the intermediate position, the third slider 400 is firstly pushed to slide toward the opening, the first protrusion 410 abuts against the surface 602 to drive the connecting portion 600 to slide, and the surface 603 on the connecting portion 600 pushes the side surface of the second mounting groove 310 to drive the second slider 300 to slide. When the locking structure 10 moves to the intermediate position, the surface 306 abuts against the second protrusion 420, the second slider 300 stops moving, the surface 301 on the second slider 300 is separated from the first step surface 201 on the first slider 200, the first slider 200 slides toward the first side surface 101 under the action of the first elastic member 710, the pushing surface 205 slides toward the first side surface 101, and the surface 601 on the connecting portion 600 always abuts against the pushing surface 205 under the action of the second elastic member 720, that is, the connecting portion 600 also slides toward the first side surface 101. While the face 301 on the second slider 300 abuts against the connecting flat face 204. The first slider 200 stops moving, the connecting portion 600 disengages the surface 602 from the first protrusion 410 due to the lateral sliding, and the third slider 400 no longer brings the connecting portion 600 and the second slider 300 to slide longitudinally. In this process, since the second slider 300 and the third slider 400 move synchronously, the lock arm 510 and the third slider 400 do not slide relative to each other, and the first inclined surface 401 always abuts against the second inclined surface 503b, so that the lock arm 510 slides only in the longitudinal direction.

And a second locking process: during the movement of the locking structure 10 from the intermediate position to the locking position, the connecting portion 600 is kept stationary since the connecting portion 600 is no longer in contact with the first protrusion 410, and thus the second slider 300 and the first slider 200 are also kept stationary. The third slider 400 continues to slide towards the opening direction, the first inclined surface 401 has a tendency of being disengaged from the surface 503, the two locking arms 510 are opened under the action of the third elastic member 730, so that the surface 503 is always abutted against the first inclined surface 401, when the first inclined surface 401 is abutted against the third inclined surface 503a, the locking structure 10 is located at the unlocking position, and the locking ends 512 on the locking arms 510 are clamped in the locking holes 911 on the external device, so as to complete the locking.

A first unlocking process: the movement between the lock arm 510 and the third slider 400 during the movement of the locking structure 10 from the locked position to the intermediate position is opposite to the second unlocking process, and will not be described in detail herein. When the third slider 400 moves to the sixth position, the first protrusion 410 abuts against the connection inclined surface 203 of the first slider 200, and the first slider 200 is driven to slide from the second position to the first position by the abutment. In the sliding process of the first slider 200, the connecting portion 600 is driven to slide, so that the projections of the connecting portion 600 and the first protruding portion 410 in the longitudinal direction are overlapped, but the connecting portion 600 does not hinder the sliding of the third slider 400 because the first protruding portion 410 is closer to the third side surface 103 than the connecting portion 600. 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 obstructs the sliding of the second slider 300 to the third position, and the second protrusion 420 on the third slider 400 abuts against the second slider 300.

A second unlocking process: in the process that the locking structure 10 moves from the middle position to the unlocking position, the third slider 400 pushes the surface 306 on the second slider 300 through the second protrusion 420, so as to drive the second slider 300 to slide to the third position, thereby completing unlocking.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
