[0034] Example 2

[0035] Reference Figure 2 to Figure 4 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0036] Specifically, the disassembly component 202 includes a motor 202a and a threaded rod 202b. The motor 202a is fixed in the cabinet 101. One end of the threaded rod 202b is fixed to the output end of the motor 202a. The other end of the threaded rod 202b is rotatably connected to the inner wall of the cabinet 101.

[0037] The motor 202a drives the threaded rod 202b to rotate, and the threaded rod 202b converts the rotational force into a driving force, so that the floor 201 can be disassembled at a uniform speed, thereby improving the stability during disassembly.

[0038] Specifically, the disassembly member 202 further includes a push block 202c, which moves outside the threaded rod 202b and moves inside the cabinet 101. A slide groove V is provided inside the cabinet 101, and the push block 202c moves inside the slide groove V.

[0039] The pushing block 202c is rectangular, and a threaded groove is provided inside the pushing block 202c. The pushing block 202c is driven to move horizontally by the rotation of the threaded rod 202b, so that the pushing block 202c drives the floor 201 to move horizontally.

[0040] Specifically, the limiting member 203 includes a clamping block 203a and a spring 203b. The clamping block 203a moves inside the pushing block 202c. Two ends of the spring 203b are respectively fixed to the pushing block 202c and the clamping block 203a.

[0041] The block 203a is a right-angled trapezoid. The inclined surface of the block 203a is squeezed by the floor 201. The block 203a is squeezed and moves vertically into the pushing block 202c. The spring 203b is squeezed and deformed until the end of the floor 201 fits against the side of the pushing block 202c. The reaction force of the spring 203b pushes the block 203a to move and reset. The block 203a enters the clamping groove of the floor 201 and clamps with the floor 201, thereby completing the fixation of the floor 201.

[0042] Specifically, the unlocking member 204 includes a squeezing block 204 a , and the squeezing block 204 a is fixed to the inner wall of the sliding groove V.

[0043] One side of the squeezing block 204a is provided with an inclined surface. By providing the squeezing block 204a, when the floor 201 is disassembled, the fixing of the device to the floor 201 can be automatically cancelled.

[0045] The force transmission block 204b is L-shaped, the limit block 204c is a rectangular rod, the limit block 204c is vertically fixed to the force transmission block 204b, and the clamping block 203a is driven to move vertically by moving the force transmission block 204b vertically, so that the clamping block 203a is separated from the clamping groove of the floor 201, so that the floor 201 is disassembled, so that the device is convenient for replacing the floor 201, and it is convenient for cleaning and maintenance of the floor 201.

[0046] Example 3

[0047] Reference Figure 4 and Figure 5 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0048] Specifically, the unlocking member 204 further includes a push rod 204d, and the push rod 204d moves outside the limiting block 204c.

[0049] The push rod 204d is rectangular, and a slope is provided on the push rod 204d corresponding to the extrusion block 204a. The slope of the extrusion block 204a is used to squeeze the slope of the push rod 204d, and the push rod 204d is squeezed to move vertically upward. The push rod 204d pushes the force transmission block 204b to move vertically upward, thereby disassembling the floor 201. A slot is provided on the push rod 204d corresponding to the limit block 204c, and the limit block 204c moves in the slot. The stability of the push rod 204d pushing the force transmission block 204b is improved through the clamping and limiting of the slot and the limit block 204c.

[0050] Specifically, the waterproof member 205 includes a reel 205a and a waterproof membrane 205b. The reel 205a rotates in the cabinet 101, and the waterproof membrane 205b moves outside the reel 205a.

[0051] The end of the waterproof membrane 205b is fixed to one side of the pushing block 202c. When the pushing block 202c pushes the floor 201, the waterproof membrane 205b will be pulled out. The winding rod 205a is cylindrical, and the waterproof membrane 205b is made of high and low temperature resistant material. When the winding rod 205a rotates counterclockwise, the waterproof membrane 205b is stored, and when the winding rod 205a rotates clockwise, the waterproof membrane 205b is released. Through the setting of the waterproof membrane 205b, the situation that water enters the slide groove V and the surface of the threaded rod 202b when disassembling the floor 201, causing corrosion and damage to parts, is avoided, thereby improving the service life of the device and reducing the cost of use.

[0052] Specifically, the waterproof member 205 further includes a partition plate 205c, and the partition plate 205c is fixed to the outside of the rolling rod 205a.

[0053] The partition 205c is in the shape of a disk. By providing the partition 205c, the waterproof membrane 205b is prevented from deviating during the retraction and extension process, thereby preventing the waterproof function from being reduced, thereby increasing the service life of the device.

[0054] Specifically, the waterproof member 205 further includes a torsion spring 205d, the outer end of the torsion spring 205d is fixed to the inner wall of the cabinet 101, and the inner end of the torsion spring 205d is fixed to the outer side of the winding rod 205a.

[0055] When the inner end of the torsion spring 205d rotates clockwise following the winding rod 205a, it is in a tightened state. When the pushing block 202c pulls the waterproof membrane 205b to extend, the waterproof membrane 205b drives the winding rod 205a to rotate clockwise, and the winding rod 205a drives the torsion spring 205d to rotate clockwise. When the pushing block 202c moves in the opposite direction, the reaction force of the torsion spring 205d will drive the winding rod 205a to rotate counterclockwise, so that the winding rod 205a can rewind the waterproof membrane 205b.

[0056] When in use, when disassembling the floor 201, first, start the motor 202a, the motor 202a drives the threaded rod 202b to rotate, the threaded rod 202b drives the pushing block 202c to move, the pushing block 202c pushes the floor 201 to the outside of the cabinet 101, the pushing block 202c pulls the waterproof membrane 205b to extend, the waterproof membrane 205b drives the winding rod 205a to rotate clockwise, the winding rod 205a drives the torsion spring 205d to rotate clockwise until the inclined surface of the squeezing block 204a squeezes the inclined surface of the push rod 204d, the push rod 204d is squeezed and moves vertically upward, the push rod 204d pushes the force transmission block 204b to move vertically upward, the force transmission block 204b drives the clamping block 203a to move vertically, so that the clamping block 203a is separated from the clamping groove of the floor 201, so that the floor 201 is disassembled. When installing, first, push the floor 201 toward the pushing block 202c, the floor 20 The inclined surface of the clamping block 203a is squeezed, and the clamping block 203a is squeezed to move vertically into the pushing block 202c, and the spring 203b is squeezed to deform until the end of the floor 201 fits with the side of the pushing block 202c, and the reaction force of the spring 203b pushes the clamping block 203a to move and reset, and the clamping block 203a enters the clamping groove of the floor 201 and is clamped with the floor 201, thereby completing the fixation of the floor 201, starting the motor 202a, the motor 202a drives the threaded rod 202b to rotate, the threaded rod 202b drives the pushing block 202c to move, and the pushing block 202c drives the floor 201 to move into the cabinet 101, and the reaction force of the torsion spring 205d drives the winding rod 205a to rotate counterclockwise, so that the winding rod 205a rewinds the waterproof membrane 205b, until the pushing block 202c fits with the inner wall of the cabinet 101, thereby completing the replacement and installation of the floor 201.
