Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, and in particular to a washing machine. Background Art

[0002] At present, the common dishwashers on the market generally include a cabinet and a spray device arranged in the cabinet, and the spray device is used to draw water from the bottom of the cabinet into the water spraying component and spray it into the washing chamber to wash the dishes. The washing chamber volume of most dishwashers is fixed and cannot be changed according to the number of dishes to be washed. When the number of dishes to be washed is small, placing the dishes in a larger washing chamber for washing not only affects the washing effect, but also causes a waste of water resources.

[0003] In addition, for some dishwashers with larger capacity, users are accustomed to placing the dishes in the dishwasher for storage after washing. In this case, if fewer dishes are used for each meal, the stored dishes will need to be washed together when washing the dishes next time, which will also cause a waste of water and electricity resources.

[0004] In response to the above problems, the Chinese utility model patent with patent number CN202023348649.2 (publication number CN215383808U) discloses "A dishwasher", which includes: a box body, having an inner cavity; a partition assembly, arranged in the inner cavity of the box body, for dividing the inner cavity of the box body into relatively independent upper and lower spaces; the partition assembly includes: a fixed plate, horizontally placed in the middle of the box body and connected to the inner wall of the box body; a movable plate, movably arranged on the fixed plate, for cooperating with the fixed plate to separate the upper space from the lower space or connect the upper space with the lower space; also includes: a surrounding plate, arranged on the lower wall surface of the fixed plate, and a relatively independent installation compartment is formed between the fixed plate and the inner wall of the box body; a driving member, arranged in the installation compartment, and the power output shaft passes through the surrounding plate and is connected to the movable plate.

[0005] When the number of dishes to be washed is small, the movable plate of the partition assembly moves relative to the fixed plate to separate the upper space from the lower space. The upper space can be used to place washed dishes, and the lower space can be sprayed and washed separately, which not only makes full use of the box space, but also helps to save energy such as water and electricity. When the number of dishes to be washed is large, the movable plate of the partition assembly moves relative to the fixed plate to connect the upper space with the lower space, and the dishes in the upper space and the lower space are washed at the same time.

[0006] However, in this patent, the power for the movement of the movable plate is completely provided by the driving member, which consumes a large amount of energy. In addition, when the movable plate moves backward into place, the user cannot sense whether the movable plate has moved into place, and the user experience needs to be further improved. Summary of the invention

[0007] The first technical problem to be solved by the present invention is to provide a cleaning machine capable of saving energy consumption in view of the current status of the prior art.

[0008] The second technical problem to be solved by the present invention is to provide a cleaning machine capable of reminding the user when the movable plate moves into position along the second direction in view of the current status of the prior art.

[0009] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a cleaning machine, comprising

[0010] A box body having an inner cavity;

[0011] A partition assembly is arranged in the inner cavity of the box body, and the partition assembly can separate the inner cavity of the box body into relatively independent upper space and lower space. The partition assembly includes

[0012] A fixing plate, which is horizontally placed in the middle of the box body and connected to the inner side wall of the box body;

[0013] a movable plate arranged to be movable relative to the fixed plate in a horizontal direction, the movable plate being used to cooperate with the fixed plate to separate the upper space from the lower space or to connect the upper space with the lower space, a moving direction of the movable plate toward separating the upper space from the lower space being defined as a first direction, and a moving direction of the movable plate toward connecting the upper space with the lower space being defined as a second direction;

[0014] It is characterized by that it also includes

[0015] A slide groove is provided on the fixed plate, the slide groove extends along a first direction and a second direction, and a locking groove is provided at the end of the slide groove;

[0016] A slider is disposed on the movable plate and can slide along the slide groove. When the movable plate cooperates with the fixed plate to connect the upper space with the lower space, the slider can be positioned in the locking groove;

[0017] A locking assembly, comprising a first locking member provided on the movable plate and a second locking member provided on the fixed plate, wherein the first locking member and the second locking member can be locked and matched, and in this state, the slider is positioned in the locking groove;

[0018] An unlocking member, drivingly connected to the first locking member or the second locking member, so that the first locking member and the second locking member are unlocked, in which state the slider can be disengaged from the locking groove;

[0019] The first elastic member acts on the movable plate, so that the movable plate always maintains a tendency to move along the first direction.

[0020] The technical solution adopted by the present invention to solve the above second technical problem is: when the slider enters the locking groove, the slider hits the locking groove to make a sound.

[0021] In order to facilitate the cooperation between the fixed plate and the movable plate to separate or connect the upper space and the lower space, the fixed plate is arranged close to the rear side of the box body, and a gap is formed between the fixed plate and the front side wall of the box body for connecting the upper space and the lower space. The movable plate can slide back and forth on the fixed plate and is used to open or close the gap. The first direction is forward and the second direction is backward.

[0022] To facilitate assembly, the movable plate is arranged above or below the fixed plate. When the notch is open, the movable plate overlaps the upper side or the lower side of the fixed plate. When the notch is closed, at least part of the movable plate intersects with the fixed plate and covers the notch.

[0023] In order to position the slider in the locking groove and prevent it from being easily disengaged from the locking groove, the entire slide groove extends in the front-to-back direction, and the slide groove includes a first slide, a second slide and a third slide. The rear end of the first slide is forked to form the second slide and the third slide respectively, and the third slide is located above the second slide. The rear end of the third slide is connected with the rear end of the second slide, and the locking groove is formed at the connection between the third slide and the second slide. The slider can only slide into the third slide along the second slide in one direction, but cannot slide from the second slide into the first slide. In this way, when the movable plate moves forward, the slider needs to move upward into the third slide first before the movable plate can move forward, and the first elastic member only gives the movable plate a force to move forward. Therefore, when the first locking member and the second locking member are locked and matched, the movable plate cannot easily be caused to disengage from the locking groove under the action of the first elastic member.

[0024] In order to make the slider slide only along the second slideway into the third slideway in one direction, the slope of the connection between the third slideway and the second slideway is reduced to form the locking groove, the side wall of the locking groove is the ramp connecting it with the second slideway and the third slideway, the first ramp of the locking groove is connected with the rear end of the second slideway, the second ramp of the locking groove is connected with the rear end of the third slideway, the height of the second ramp is lower than the height of the first ramp, and the second ramp is arc-shaped. Because the height of the second ramp is lower than the height of the second ramp, when the slider moves out of the locking groove, it will slide to the third slideway first.

[0025] In order to make the third slideway and the first slideway cooperate well and enable the slider to slide smoothly from the third slideway into the first slideway, the third slideway includes a first section connected with the locking groove and a second section connected with the first section and the first slideway, the second section is inclined downward from the back to the front, and the first section is an arc-shaped structure arched in the direction away from the second slideway. The arc-shaped structure reduces the movement resistance of the slider, and the second section is inclined so that the slider can slide into the first slideway along the second section under the action of its own gravity.

[0026] In order to facilitate the sliding block to enter the second slideway from the first slideway and enter the first slideway from the third slideway, the rear end of the first slideway and the front end of the second slideway are connected by a first step with a reduced slope, and the front end of the third slideway and the rear end of the first slideway are connected by a second step with a reduced slope. The reduced slope is conducive to the smooth sliding of the sliding block.

[0027] In order to prevent the slider from making hard contact with the slide slot and damaging the components during its movement along the slide slot, the movable plate is provided with a first mounting plate, the first mounting plate is provided with a first mounting hole with an opening facing the slide slot, one end of the slider is inserted in the first mounting hole, and the other end is inserted in the slide slot, the slider can slide along the axial direction of the first mounting hole, and the first mounting hole is provided with a second elastic member that acts on the slider to keep the slider always moving in a direction away from the first mounting hole. In this way, the slider and the slide slot are in elastic contact, and in particular, the slider can well adapt to the ramp in the slide slot.

[0028] In order to improve the moving stability of the moving plate, a slide rail is further provided on the fixed plate behind the slide groove, the slide rail extends in the front-back direction, the slider is provided at the front of the moving plate, and a sliding member is further provided on the moving plate behind the slider, the sliding member can be accommodated in the slide rail and move along the slide rail. In this way, the front and rear of the moving plate are both connected to the fixed plate, which can improve the moving stability of the moving plate.

[0029] Because when the moving plate just starts to move forward, the slider enters the third slide track, and the front part of the moving plate will move upward first, so in order to prevent the moving plate from tilting, the rear part of the slide rail is tilted downward from front to back, so that when the moving plate just starts to move forward, the rear part of the moving plate also moves upward to ensure the overall balance of the moving plate.

[0030] Similarly, in order to prevent the sliding member from hard contact with the slide rail and damage to the components, the movable plate is provided with a second mounting plate, the second mounting plate is provided with a second mounting hole with an opening facing the slide rail, one end of the sliding member is inserted in the second mounting hole, and the other end is inserted in the slide rail, the sliding member can slide along the axial direction of the second mounting hole, and the second mounting hole is provided with a third elastic member that acts on the sliding member to keep the sliding member always moving in a direction away from the second mounting hole. In this way, there is elastic contact between the sliding member and the slide rail.

[0031] The locking assembly can have a variety of structural forms. In order to prevent the movable plate from moving upward and causing the slider to escape from the locking groove, the structure is simple. The first locking piece is arranged at the front of the movable plate, the first locking piece is L-shaped, and a positioning groove is formed between the first locking piece and the upper end surface of the movable plate. The second locking piece includes a mounting shaft installed on the fixed plate and a positioning block provided on the outer peripheral wall of the mounting shaft. The mounting shaft is vertically arranged. When the upper space is connected to the lower space, the positioning block is located in the positioning groove, and the bottom wall surface of the positioning block is against the upper wall surface of the movable plate to prevent the movable plate from moving upward.

[0032] In order to unlock the first locking member and the second locking member, a receiving groove with a notch facing forward is provided on the fixing plate, and the installation shaft can rotate relative to the fixing plate, so that the positioning block is located in the positioning groove or the receiving groove, and a driving block is provided on the outer peripheral wall of the installation shaft, and the output end of the unlocking member can abut against the driving block to push the installation shaft to rotate. The installation shaft rotates, so that the installation shaft rotates, the positioning block escapes from the positioning groove and enters the receiving groove, and the movable plate can move upward.

[0033] In order to improve the working reliability of the cleaning machine, a trigger is provided on the movable plate, and a micro switch is provided on the fixed plate. When the upper space of the inner cavity of the box is connected to the lower space, the trigger triggers the micro switch; or, a trigger is provided on the fixed plate, and a micro switch is provided on the movable plate. When the upper space of the inner cavity of the box is connected to the lower space, the trigger triggers the micro switch. When the micro switch is triggered, it means that the movable plate moves into place, and the upper space and the lower space are connected. At this time, the cleaning machine can be controlled to perform full-cavity washing. The setting of the micro switch makes the working safety and reliability of the cleaning machine high.

[0034] In order to enable the partition assembly to effectively separate the upper space from the lower space, a sealing strip is provided at the front of the movable plate, the front side of the box body is open to form the inner cavity, and the front side of the box body is provided with a door body that can open or close the opening, and when the door body is closed, the sealing strip abuts against the door body. The sealing strip abuts against the door body to reduce the connection between the upper space and the lower space, so as to prevent the washing water from entering the upper space when the lower space is washed. The first elastic member not only serves as a power source to drive the movable plate to move forward, but also enables the sealing strip to abut tightly against the door body to improve the sealing performance.

[0035] Compared with the prior art, the advantages of the present invention are as follows: 1. By setting a locking groove, a slider and a locking assembly, after the first locking member and the second locking member are unlocked, the movable plate will move along the first direction under the action of the first elastic member, and the movable plate can be manually pushed back along the second direction, so that the movement of the movable plate does not completely rely on motor energy and electrical components, and the energy consumption is small; 2. When the slider enters the locking groove, the slider hits the locking groove and makes a sound, prompting the user that the movable plate has been pushed back into place, otherwise the user pushes the movable plate excessively, which is easy to cause damage to the slider.

[0047] The present invention is further described in detail below with reference to the accompanying drawings.

[0048] like Figures 1 to 11 As shown, the cleaning machine of this preferred embodiment includes a housing 1, a partition assembly, a locking assembly, an unlocking member, and the like.

[0049] like Figure 1 As shown, the box body 1 has an inner cavity 11, and the partition assembly is arranged in the inner cavity 11 of the box body 1. The partition assembly can separate the inner cavity 11 of the box body 1 into relatively independent upper space 11a and lower space 11b.

[0050] like Figure 1 , 2 As shown in Figure 10, the partition assembly includes a fixed plate 2 and a movable plate 3. The fixed plate 2 is horizontally placed in the middle of the box body 1 and fixedly connected to the inner wall of the box body 1. The movable plate 3 is arranged to be movable relative to the fixed plate 2 in a horizontal direction, and is used to cooperate with the fixed plate 2 to separate the upper space 11a from the lower space 11b or connect the upper space 11a with the lower space 11b. The moving direction of the movable plate 3 to separate the upper space 11a from the lower space 11b is defined as a first direction, and the moving direction of the movable plate 3 to connect the upper space 11a with the lower space 11b is defined as a second direction.

[0051] like Figure 1 , 10 As shown, in this embodiment, the fixed plate 2 is arranged close to the rear side of the box body 1, and a gap 11c is formed between the fixed plate 2 and the front side wall of the box body 1 for connecting the upper space 11a and the lower space 11b. The movable plate 3 is arranged below the fixed plate 2, and the movable plate 3 can be slid forward and backward on the fixed plate 2 and is used to open or close the gap 11c.

[0052] like Figure 1 As shown, when the notch 11c is opened, the movable plate 3 overlaps the lower side of the fixed plate 2; Fig.10As shown, when the notch 11c is closed, at least part of the movable plate 3 is interlaced with the fixed plate 2 and covers the notch 11c. As can be seen from the above, the first direction is the forward direction, and the second direction is the backward direction.

[0053] Of course, the movable plate 3 can also be set above the fixed plate 2. When the notch 11c is open, the movable plate 3 overlaps the upper side of the fixed plate 2. When the notch 11c is closed, at least part of the movable plate 3 intersects with the fixed plate 2 and covers the notch 11c.

[0054] like Figure 5 , 6 As shown in Figures 7 and 8, the left and right side walls of the fixed plate 2 are both provided with slide grooves 21, and the left and right sides of the movable plate 3 are both provided with sliders 31 that slide and cooperate with the slide grooves 21. Because the cooperation structure of the two groups of sliders 31 and the slide grooves 21 is the same, only one group of sliders 31 and the slide grooves 21 will be introduced below.

[0055] The slide groove 21 as a whole extends in the front-to-back direction, and a locking groove 210 is provided at the rear end of the slide groove 21. The slider 31 is provided on the movable plate 3 and can slide along the slide groove 21. When the movable plate 3 cooperates with the fixed plate 2 to connect the upper space 11a and the lower space 11b, the slider 31 can be positioned in the locking groove 210. In addition, when the slider 31 enters the locking groove 210, the slider 31 hits the locking groove 210 to make a sound, prompting the user that the movable plate 3 is pushed into place. Because the movable plate 3 of this embodiment is manually pushed back by the user, if there is no reminder of being in place, the user is likely to push it too much, causing the slider 31 to interfere with the locking groove 210, thereby damaging the slider 31 or the locking groove 210.

[0056] like Figure 2 , 3 As shown in , 4, the locking assembly includes a first locking piece 32 arranged on the movable plate 3 and a second locking piece 22 arranged on the fixed plate 2. The first locking piece 32 and the second locking piece 22 can be locked and matched. In this state, the slider 31 is positioned in the locking groove 210 and cannot escape from the locking groove 210.

[0057] The first elastic member 4 acts on the moving plate 3, so that the moving plate 3 always maintains the tendency to move along the first direction. The unlocking member is drivingly connected to the first locking member 32 or the second locking member 22, so that the first locking member 32 and the second locking member 22 are unlocked. After unlocking, the slider 31 can be disengaged from the locking groove 210, and the moving plate 3 moves forward under the action of the first elastic member 4, separating the upper space 11a from the lower space 11b.

[0058] like Figure 5 , 6As shown, in this embodiment, the slide groove 21 includes a first slide 211, a second slide 212 and a third slide 213. The rear end of the first slide 211 is forked to form the second slide 212 and the third slide 213 respectively. The third slide 213 is located above the second slide 212. The rear end of the third slide 213 is connected to the rear end of the second slide 212. The slider 31 can only slide unidirectionally along the second slide 212 into the third slide 213.

[0059] The third slideway 213 includes a first section 2131 connected to the locking groove 210 and a second section 2132 connected to the first section 2131 and the first slideway 211 . The second section 2132 is inclined downward from back to front. The first section 2131 is an arc-shaped structure arched away from the second slideway 212 .

[0060] The rear end of the first slide 211 and the front end of the second slide 212 are connected via a first step 214 with a reduced slope, and the front end of the third slide 213 and the rear end of the first slide 211 are connected via a second step 215 with a reduced slope. The reduced slope is conducive to the smooth sliding of the slider 31.

[0061] The slope of the connection between the third slide 213 and the second slide 212 is reduced to form a locking groove 210. The side wall of the locking groove 210 is the ramp connected with the second slide 212 and the third slide 213. The first ramp 2101 of the locking groove 210 is connected with the rear end of the second slide 212, and the second ramp 2102 of the locking groove 210 is connected with the rear end of the third slide 213. The height of the second ramp 2102 is lower than the height of the first ramp 2101, and the second ramp 2102 is arc-shaped.

[0062] Because the height of the second ramp 2102 is lower than that of the second ramp 2102, the slider 31 will slide preferentially toward the third slideway 213 when it moves out of the locking groove 210. In this way, when the moving plate 3 moves forward, the slider 31 needs to move upward into the third slideway 213 first, so that the moving plate 3 can move forward.

[0063] When the locking assembly is in the locked state, it can limit the upward movement of the slider 31 and prevent the slider 31 from falling out of the locking groove 210. Figure 2 , 3 As shown in Figures 4 and 5, the first locking member 32 is arranged at the front part of the movable plate 3, the first locking member 32 is L-shaped, a positioning groove 34 is formed between the first locking member 32 and the upper end surface of the movable plate 3, the second locking member 22 is arranged on the fixed plate 2, the second locking member 22 includes a mounting shaft 221 rotatably mounted on the fixed plate 2, the mounting shaft 221 is vertically arranged, and a positioning block 222 and a driving block 223 are provided on the outer peripheral wall of the mounting shaft 221.

[0064] The fixing plate 2 is provided with a receiving groove 23 with a notch facing forward, and the unlocking member 5 can be a motor or a solenoid valve, and the output end of the unlocking member 5 can abut against the driving block 223 to push the mounting shaft 221 to rotate, so that the positioning block 222 is located in the positioning groove 34 or the receiving groove 23. In this embodiment, the output end of the unlocking member 5 is connected to the driving block 223. Of course, the output end of the unlocking member 5 can also be in contact with the driving block 223 only when the unlocking member 5 is working.

[0065] When the upper space 11a is connected to the lower space 11b, the positioning block 222 is located in the positioning groove 34, and the bottom wall surface of the positioning block 222 can abut against the upper wall surface of the movable plate 3 to prevent the movable plate 3 from moving upward; when the positioning block 222 escapes from the positioning groove 34 and enters the accommodating groove 23, the movable plate 3 can move upward.

[0066] like Figure 7 , 8 As shown, the movable plate 3 is provided with a first mounting plate 33, and the first mounting plate 33 is provided with a first mounting hole 331 with an opening toward the slide groove 21. One end of the slider 31 is inserted in the first mounting hole 331, and the other end is inserted in the slide groove 21. The slider 31 can slide along the axial direction of the first mounting hole 331. The first mounting hole 331 is provided with a second elastic member 311 that acts on the slider 31 to keep the slider 31 moving in a direction away from the first mounting hole 331. In this way, the slider 31 is in elastic contact with the slide groove 21, and can especially adapt well to the ramp in the slide groove 21.

[0067] The second elastic member 311 is a spring, one end of which abuts against the slider 31, and the other end abuts against the bottom wall of the first mounting hole 331. A first lateral outward protrusion 312 is provided on the outer peripheral wall of the slider 31, and the outer wall surface of the first lateral outward protrusion 312 is a conical surface with a gradually decreasing diameter along the direction of its insertion into the first mounting hole 331. The first lateral outward protrusion 312 can be elastically deformed when passing through the first mounting hole 331. After the first lateral outward protrusion 312 enters the first mounting hole 331, the first lateral outward protrusion 312 buckles against the wall surface of the first mounting plate 33.

[0068] like Figure 5 , 7 As shown in Figures 9, a slide rail 24 is further provided on the fixed plate 2 at the rear of the slide groove 21. The slide rail 24 extends in the front-to-back direction. The slider 31 is provided at the front of the movable plate 3. The movable plate 3 is also provided with a sliding member 35 located at the rear of the slider 31. The sliding member 35 can be accommodated in the slide rail 24 and move along the slide rail 24. The rear of the slide rail 24 is inclined downward from front to rear.

[0069] In this way, the front and rear parts of the movable plate 3 are connected to the fixed plate 2, which can improve the movement stability of the movable plate 3. Because when the movable plate 3 just starts to move forward, the slider 31 enters the third slideway 213, and the front part of the movable plate 3 will move upward first. Therefore, in order to prevent the movable plate 3 from tilting, when the movable plate 3 just starts to move forward, the rear part of the movable plate 3 also moves upward to ensure the overall balance of the movable plate 3.

[0070] Similarly, a second mounting plate 36 is provided on the movable plate 3, and a second mounting hole 361 is provided on the second mounting plate 36, the opening of which faces the slide rail 24. One end of the sliding member 35 is inserted in the second mounting hole 361, and the other end is inserted in the slide rail 24. The sliding member 35 can slide axially along the second mounting hole 361. The second mounting hole 361 is provided with a third elastic member 351 which acts on the sliding member 35 so that the sliding member 35 always maintains a tendency to move in a direction away from the second mounting hole 361, so that there is elastic contact between the sliding member 35 and the slide rail 24.

[0071] The third elastic member 351 is a spring, one end of which is against the sliding member 35, and the other end of which is against the bottom wall of the second mounting hole 361. A second lateral outward protrusion 352 is provided on the outer peripheral wall of the sliding member 35, and the outer wall surface of the second lateral outward protrusion 352 is a conical surface with a gradually decreasing diameter along the direction in which the second lateral outward protrusion 352 is inserted into the second mounting hole 361. The second lateral outward protrusion 352 can be elastically deformed when passing through the second mounting hole 361. After the second lateral outward protrusion 352 enters the second mounting hole 361, the second lateral outward protrusion 352 buckles against the wall surface of the second mounting plate 36.

[0072] The movable plate 3 is provided with a fixed block 37, the fixed block 37 is provided with a trigger 371, and the fixed plate 2 is provided with a micro switch 25. When the upper space 11a of the inner cavity 11 of the box body 1 is connected to the lower space 11b, the trigger 371 triggers the micro switch 25. When the micro switch 25 is triggered, it means that the movable plate 3 is moved into place, the upper space 11a and the lower space 11b are connected, and the cleaning machine can be controlled to perform full cavity washing at this time. The setting of the micro switch 25 makes the cleaning machine safe and reliable. Of course, the trigger 371 can also be provided on the fixed plate 2, and the micro switch 25 can be provided on the movable plate 3. When the upper space 11a of the inner cavity 11 of the box body 1 is connected to the lower space 11b, the trigger 371 triggers the micro switch 25.

[0073] The front of the movable plate 3 is provided with a sealing strip 38, the front side of the box body 1 is open to form an inner cavity 11, and the front side of the box body 1 is provided with a door body (not shown in the figure) that can open or close the opening. When the door body is closed, the sealing strip 38 abuts against the door body, and the sealing strip 38 can abut against the door body tightly under the action of the first elastic member 4. The sealing strip 38 abuts against the door body, reducing the communication between the upper space 11a and the lower space 11b, so as to prevent the washing water from entering the upper space 11a when the lower space 11b is washed.

[0074] The working process of the cleaning machine of this embodiment is as follows:

[0075] In the state of full cavity washing, the movable plate 3 cooperates with the fixed plate 2 to connect the upper space 11a with the lower space 11b, the positioning block 222 is positioned in the positioning groove 34, the slider 31 is positioned in the locking groove 210, and the sliding member 35 is located at the rear end of the slide rail 24;

[0076] When half-cavity washing is required, the unlocking member 5 drives the mounting shaft 221 to rotate, so that the positioning block 222 escapes from the positioning groove 34 and enters the accommodating groove 23, and the movable plate 3 moves forward under the action of the first elastic member 4. Due to the track restriction of the third slideway 213, the front part of the movable plate 3 will first move upward during the forward movement, and the rear part of the movable plate 3 moves along the track of the slide rail 24 until the sealing strip 38 abuts against the door body;

[0077] When full-cavity washing is required, the movable plate 3 is manually pushed back, the slider 31 moves along the first slide 211 and the second slide 212, and the sliding member 35 moves along the slide rail 24 until the slider 31 enters the locking groove 210. After the user hears the impact sound of the slider 31 entering the locking groove 210, the sliding member 35 is at the end of the slide rail 24 and no longer continues to push the movable plate 3. The unlocking member 5 drives the mounting shaft 221 to rotate, and the positioning block 222 is positioned in the positioning groove 34.
