[0008] By adopting the above technical solution, the screw rod rotates while controlling the sliding of the slide plate, and the locking piece is driven to move through the control component while the slide plate slides. When the locking piece rotates so that the locking protrusion is embedded in the card slot, the screw rod cannot continue to rotate to achieve locking. When the locking piece rotates so that the locking protrusion is away from the card slot, the screw rod can rotate to achieve unlocking. The state of the screw rod is controlled by the control component, which is convenient for users to use.

[0009] Preferably, the control component includes a support seat, an action piece, a crank arm, a connecting rod and a linkage member, the support seat is fixedly connected to the base plate, the upper end of the support seat is provided with a guide groove, the length direction of the guide groove is parallel to the axis of the screw rod, the action piece is slidably embedded in the guide groove, the action piece is fixedly connected to the skateboard, one end of the crank arm is hinged to the support seat, the other end of the crank arm is hinged to one end of the connecting rod, the other end of the connecting rod is hinged to the locking piece, and the action piece is connected to the crank arm through a linkage member.

[0010] By adopting the above technical solution, the sliding of the skateboard drives the action piece to slide synchronously, and the guide groove guides the sliding of the action piece, so that the action piece can slide stably along the correct path. The action piece drives the crank arm to rotate through the linkage part. When the crank arm rotates, the locking piece is driven to rotate through the connecting rod. The state of the screw rod is controlled by the cooperation of the linkage part and the action piece, which is convenient for users to use.

[0011] Preferably, the linkage comprises a locking plate, an anti-slip block and a first tension spring, the support seat is provided with a limiting slot, the length direction of the limiting slot is perpendicular to the length direction of the guide slot, the support seat is provided with a accommodating cavity, the limiting slot is connected to the accommodating cavity, and the limiting slot, the accommodating cavity and the crank arm are all arranged on the side of the guide slot away from the slide plate, the accommodating cavity is arranged between the crank arm and the locking plate, the crank arm is fixedly connected to a connecting plate towards one end of the locking plate, the connecting plate extends into the accommodating cavity, the connecting plate is provided with a connecting slot towards one end of the locking plate, the hinged end of the crank arm is arranged on the side of the connecting slot close to the guide slot, the locking plate is arranged in the limiting slot, the lower end of the locking plate passes through the connecting slot and is fixedly connected to the anti-slip block, the upper end of the action plate is fixedly connected with a protrusion, the protrusion is used to abut the lower end of the locking plate, the first tension spring is arranged on the side of the guide slot away from the limiting slot, one end of the first tension spring is fixedly connected to one end of the locking plate, and the other end of the first tension spring is fixedly connected to the support seat.

[0012] By adopting the above technical solution, when the protrusion abuts against the lower end of the chain plate, one end of the chain plate is lifted up, and due to the limitation of the anti-drop block, the other end of the chain plate cannot be lifted. At the same time, the chain plate is limited by the limiting groove so that the chain plate can only tilt. The first tension spring is stretched, and the chain plate drives the connecting plate close to the guide groove. The crank arm rotates and drives the locking plate to rotate through the connecting rod, so that the locking protrusion is embedded in the slot, thereby locking the screw rod, which is convenient for users to use.

[0013] Preferably, it also includes a baffle, which is arranged on a side of the card plate away from the skateboard, and the baffle is fixedly connected to the bottom plate. The baffle is provided with a sliding opening, and the sliding opening is provided on a side of the card plate close to the support seat. The linkage also includes a button, which is slidably connected to the inner wall of the sliding opening, one end of the button is hinged to the locking plate, and the lower end of the linkage plate is provided with an avoidance groove, which extends in a direction away from the limiting groove to pass through the linkage plate, the bottom of the avoidance groove is used for abutment by the protrusion, and the groove wall of the avoidance groove facing the first tension spring is used to abut the groove wall or protrusion of the guide groove, and the groove depth of the avoidance groove is less than the height of the protrusion.

[0014] By adopting the above technical solution, the locking piece rotates and the button is moved at the same time. The length of the button extending out of the sliding opening can be used to determine whether the locking protrusion is embedded in the card slot. When unlocking is required, the operator presses the button by hand to rotate the locking piece. The locking piece rotates and the connecting arm is driven to rotate through the connecting rod. The connecting arm moves and the chain piece is pulled to slide, so that the protrusion abuts against the bottom and wall of the avoidance groove to achieve unlocking. When the action piece moves to make the protrusion move away from the avoidance groove, the first tension spring restores its deformation and pulls the chain piece to reset, so that the locking and unlocking of the screw rod can work stably, which is convenient for users to use.

[0015] Preferably, it also includes a magnet, a first iron sheet and a second iron sheet, the magnet is fixedly connected to the end of the protrusion facing away from the first tension spring, the first iron sheet is fixedly connected to the groove wall of the avoidance groove facing the first tension spring, and the second iron sheet is fixedly connected to the outer wall of the connecting plate facing the first tension spring.

[0016] By adopting the above technical solution, the magnet can attract the first iron sheet and the second iron sheet. When the protrusion lifts the locking plate, the magnet's attraction to the second iron sheet makes the connecting plate close to the action plate. The stable movement of the crank arm drives the locking sheet to move through the connecting rod, and then stably locks the screw rod. When the button is manually pressed to make the button slide, the locking sheet moves through the connecting rod to drive the crank arm to move. The movement of the crank arm makes the locking sheet slide. The magnet's attraction to the first iron sheet makes the protrusion embed into the avoidance groove. The protrusion clamps the locking sheet to reduce the probability of the screw rod being locked again due to the reset of the locking sheet, thereby improving the stability of the work and facilitating user use.

[0017] Preferably, it also includes an airbag and a whistle, the bottom of the avoidance groove is provided with an airway, the airway vertically penetrates the interlocking plate, the downward opening of the airway faces the guide groove, the bag opening of the airbag is fixedly connected to the inner wall of the airway, the whistle is fixedly connected to the inner wall of the airway, the air inlet of the whistle is connected to the airbag, the air outlet of the whistle faces upward, and the airbag is used for the protrusion to abut.

[0018] By adopting the above technical solution, when the button is pushed to move, a whistle sounds, which indicates that the locking piece has moved to the correct position. If the locking piece has not moved to the correct position, when the hand releases the button, the tension of the first tension spring drives the locking piece to move, which in turn causes the crank arm to rotate, and the locking protrusion of the locking piece is re-embedded in the slot, so that the operator needs to press the button repeatedly, which is inconvenient to operate. The whistle sound can be used to determine that the button has moved to the correct position, which is convenient for users to use.

[0019] Preferably, it also includes a first rack, a gear and a second rack, the baffle is provided with an installation cavity, the installation cavity is connected to the sliding port, the first rack is fixedly connected to the outer wall of the button, the length direction of the first rack is parallel to the axis of the button, the gear rotates around its own axis and is connected to the inner wall of the installation cavity, the rotation axis of the gear is vertical, the end of the baffle away from the card plate is provided with a sliding groove, the bottom of the sliding groove is connected to the installation cavity, the warning column is slidably connected to the groove wall of the sliding groove, the second rack is fixedly connected to the outer wall of the warning column, and the second rack and the first rack are respectively meshed with the two ends of the gear.

[0020] By adopting the above technical solution, when the operator presses the button, the extension length of the button can be judged by the distance that the warning column extends out of the sliding groove, which is convenient for the user to operate the driving device.

[0021] Preferably, the outer wall of the warning column is provided with a mark, and the mark is used to remind the operator of the position of the button.

[0022] By adopting the above technical solution, markings are made on the outer wall of the warning column according to the distance the button is extended, which makes it easy to judge the state of the interlocking piece and facilitates user use.

[0023] In a second aspect, the present application provides a drawer seat, which adopts the following technical solution:

[0024] The gear train is a gear that is engaged with the gear of the driven gear and is engaged with the gear of the driven gear.

[0025] By adopting the above technical solution, the slide plate moves and drives the rotating gear to rotate, the rotating column rotates, the linkage gear rotates, the push gear rotates, the fixed column slides, the drawer slides, and the rotation of the push screw drives the drawer to slide.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The screw rod rotates while the slide plate is controlled to slide. The control component drives the locking piece to move while the slide plate slides. When the locking piece rotates so that the locking protrusion is embedded in the card slot, the screw rod cannot continue to rotate to achieve locking. When the locking piece rotates so that the locking protrusion is away from the card slot, the screw rod can rotate to achieve unlocking. The state of the screw rod is controlled by the control component, which is convenient for users to use.

[0028] 2. The magnet can attract the first iron sheet and the second iron sheet. When the protrusion lifts the locking sheet, the magnet attracts the second iron sheet so that the connecting plate is close to the action sheet. The stable movement of the crank arm drives the locking sheet to move through the connecting rod, and then stably locks the screw rod. When the button is manually pressed to slide, the locking sheet moves through the connecting rod to drive the crank arm to move. The movement of the crank arm causes the locking sheet to slide. The magnet attracts the first iron sheet so that the protrusion is embedded in the avoidance groove. The protrusion clamps the locking sheet to reduce the probability of the screw rod being locked again due to the reset of the locking sheet, thereby improving the working stability and facilitating the use of the user.

[0029] 3. When the button is pushed to move, a whistle sounds, indicating that the locking piece has moved to the correct position. If the locking piece has not moved to the correct position, when the hand releases the button, the tension of the first tension spring drives the locking piece to move, which in turn causes the crank arm to rotate, and the locking protrusion of the locking piece is re-embedded in the slot, requiring the operator to repeatedly press the button, which is inconvenient to operate. The whistle sound can be used to determine that the button has moved to the correct position, making it easier for users to use. BRIEF DESCRIPTION OF THE DRAWINGS
