[0002] In the prior art, the driver of the washing machine is fixed to the base of the washing machine body by three screws. When assembling the whole machine and disassembling and replacing the driver after sales, the screws need to be turned, which is very inconvenient, laborious and time-consuming (it takes more than 10 minutes to remove 3 screws). In addition, due to the narrow installation space of the washing machine driver, it is impossible to use common disassembly tools (electric screwdriver, long screwdriver, etc.) to operate it. This requires the operator to put his arm into the washing machine body and use a small screwdriver to fix and remove the screws, which makes the installation in the production process and the disassembly and assembly in after-sales service very inconvenient and the operation more difficult. Furthermore, after repeated use of the thread, the screw hole is easily damaged, resulting in the inability to continue to connect normally with the screw.

[0003] Accordingly, the art needs a quick disassembly and assembly device to solve the above problems. Summary of the invention

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0026] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figure 1 and Figure 2 As shown, the present invention proposes a quick disassembly device, including a bracket 1 for fixedly connecting to a base and a knob 2 for fixing a target object, the bracket 1 and the knob 2 are rotatably connected together, and the cross section of the knob 2 perpendicular to its rotation axis is a non-circular structure. In this embodiment, the base is a washing machine housing, and the target object is a driver 6. Furthermore, the non-circular structure can be composed of a cylinder and a protrusion structure arranged on the outer edge of the cylinder, or it can be directly selected from an elliptical cylinder, a cube, a cuboid or a cylinder with an irregular cross-sectional shape. Driver 6 (specifically, as shown in FIG. 1 ) Figure 3 The bracket 1 is provided with a mounting hole 61 matching the non-circular structure. During installation, the knob 2 is first inserted through the mounting hole 61, at which time the first mounting surface of the driver 6 abuts against the bracket 1, and then the knob 2 is rotated at a preset angle, at which time the knob 2 abuts against the second mounting surface of the driver 6, locking the driver 6 on the bracket 1 to prevent the driver 6 from being separated from the knob 2, thereby fixing it on the bracket 1, and then connecting and fixing the driver 6 to the base of the washing machine.

[0028] Continue reading Figure 1 and Figure 2 Preferably, the knob 2 comprises a cylindrical knob body 21 and a rib 22 disposed on the knob body 21, the rib 22 extending in a direction parallel to the axial direction of the knob body 21, and the driver 6 (specifically, Figure 3 The mounting hole 61 (as shown in FIG. 1 ) is provided with a rib groove 611 corresponding to the rib 22. During installation, the rib 22 is aligned with the rib groove 611, and then the knob 2 is allowed to pass through the mounting hole 61, and the knob body 21 is rotated by a preset angle so that the rib 22 is misaligned with the rib groove 611, thereby fixing the driver 6 on the bracket 1.

[0029] See also Figure 3 and Figure 4a, the preset rotation angle of the knob 2 is set to 90 degrees, and two symmetrical convex ribs 22 are provided on the circumferential surface of the knob body 21. It can be understood by those skilled in the art that the number of the convex ribs 22 can obviously be one, three, four, etc., and the distribution thereof can be either uniform or non-uniform, as long as they are arranged corresponding to the convex rib grooves 611 on the driver 6. In addition, the preset angle of the knob 2 can also be 30 degrees, 45 degrees, 60 degrees, etc., as long as the knob 2 interferes with the driver 6 after rotating the angle, and those skilled in the art can make equivalent changes or replacements to the relevant technical features, and the specific setting method will not be repeated here.

[0030] Continue reading Figure 2 Preferably, the bracket 1 includes a base 11 and a rotating shaft 12. The base 11 and the rotating shaft 12 can be fixedly connected or made in one piece. The base 11 can be provided with rivet holes or bolt holes, and the bracket 1 is fixed to the base of the washing machine body by riveting or screwing. The knob body 21 is provided with a fixing hole 211 that matches the rotating shaft 12. The rotating shaft 12 is inserted into the fixing hole 211 so that the knob 2 and the bracket 1 are rotatably connected together. It can be understood that bearings, bushings and other components can be added between the rotating shaft 12 and the knob body 21 to assist in rotation. Preferably, after the rotating shaft 12 is inserted into the fixing hole 211, a shaft end stopper is provided at the end of the rotating shaft 12 to fix the knob 2 to the rotating shaft 12 along the axial direction. Specifically, a threaded hole 121 is provided at the end of the rotating shaft 12, and the quick disassembly device further includes a screw 4 (i.e., an end stopper of the shaft), and the screw 4 is tightened into the threaded hole 121 so that the nut of the screw 4 abuts against the knob 2, thereby fixing the knob 2 axially to the rotating shaft 12. Preferably, the quick disassembly device of the present invention further includes a gland 5 located between the nut of the screw 4 and the knob 2, and the nut abuts against the knob 2 through the gland 5, and the screw 4 fixes the knob 2 axially to the rotating shaft 12 by pressing the gland 5. Those skilled in the art can understand that the shaft end stopper can also be configured as follows: the threaded hole 121 at the end of the rotating shaft 12 is configured as a small diameter hole, and the cover body is fixed to the end of the rotating shaft 12 by inserting the pin of the cover body with the expansion pin into the small diameter hole, so that the cover body is fixed to the end of the rotating shaft 12, thereby fixing the knob 2 to the rotating shaft 12 along the axial direction; the shaft end stopper can also be configured as follows: an external thread is provided on the protruding portion after the rotating shaft 12 is inserted into the fixing hole 211, and then an internal threaded part (such as a nut) is screwed onto the external thread so that the internal threaded part is fixed to the end of the rotating shaft 12, so that the knob 2 is fixed to the rotating shaft 12 along the axial direction. These technical solutions after modification or replacement will fall within the scope of protection of the present invention. It should be noted that the axial length of the part of the rotating shaft 12 used to install the knob 2 is slightly larger than the axial height of the knob 2, thereby providing a rotation gap for the knob 2, so that the knob 2 can be rotatably connected to the bracket 1.

[0031] Continue reading Figure 1 and Figure 2 Preferably, the base 11 includes a fixed bottom plate 111 and a columnar structure 112, the fixed bottom plate 111 and the columnar structure 112 are fixedly connected or integrally formed, a rivet hole or a bolt hole is provided on the fixed bottom plate 111, and the bracket 1 is fixed to the base of the washing machine body by riveting or screwing; the columnar structure 112 matches the mounting hole 61 of the driver 6 in the radial direction, see Figure 3 , Figure 4a and Figure 4b After the mounting hole 61 of the driver 6 is sleeved on the columnar structure 112 through the knob 2, the first mounting surface ( Figure 4a The lower end surface of the middle driver 6 abuts against the fixed base plate 111. In the installed state, the columnar structure 112 is inserted into the mounting hole 61 to limit the movement of the driver 6 in the radial direction. Preferably, a shock-absorbing pad can also be arranged between the first mounting surface of the driver 6 and the fixed base plate 111.

[0032] Continue reading Figure 2 and Figure 4bPreferably, the quick disassembly and assembly device further comprises a limiting mechanism disposed between the bracket 1 and the knob 2, and the limiting mechanism is used to fix the knob 2 and the bracket 1 together along the circumferential direction when the knob 2 rotates a preset angle, thereby preventing the knob 2 from rotating freely and playing a positioning role. Preferably, the limiting mechanism comprises a spring 31 and a ball 32, and a blind hole 1121 is disposed at one end of the columnar structure 112 close to the knob 2, and the diameter of the blind hole 1121 is set according to the diameter of the ball 32; on the other hand, a groove (not shown in the figure) matching the ball 32 is disposed at one end of the knob body 21 close to the columnar structure 112, and the groove can be set to a hemispherical or cylindrical shape, and its depth cannot be less than one-fourth of the diameter of the ball 32, nor can it exceed the radius of the ball 32. After the knob 2 is rotated to a preset angle (specifically 90 degrees), part of the ball 32 is pushed into the slot under the pressure of the spring 31. The depth of the blind hole 1121 should be sufficient to ensure that the spring 31 is in a compressed state after the spring 31 and the ball 32 are placed in the blind hole 1121 in sequence. Preferably, the limiting mechanism can also be a spring positioning bead or a ball spring pin that integrates the spring 31 and the ball 32 into one. When installing, it is only necessary to assemble the spring positioning bead or the ball spring pin into the blind hole 1121 set at one end of the columnar structure 112 close to the knob 2, which can meet the use requirements and facilitate disassembly and assembly; at the same time, due to the reliable structure of the spring positioning bead or the ball spring pin, it can also effectively avoid the situation where the ball 32 falls out, thereby reducing the difficulty of operation and further reducing the processing cost. It can be understood by those skilled in the art that if a ball spring pin or a spring positioning bead with an external thread is selected, the blind hole 1121 of the columnar structure 112 can be adaptively set as a threaded hole. Specifically, the slot is set at a corresponding position of 90 degrees to the blind hole 1121 when the quick disassembly and assembly device is in the original state. When the knob 2 is rotated by a preset angle of 90 degrees, the slot is rotated to a position corresponding to the blind hole 1121, so that the ball 32 is embedded in the slot under the pressure of the spring 31, thereby fixing the knob body 21 to the columnar structure 112 along the circumferential direction with the help of the ball 32 and the spring 31, thereby preventing the knob 2 from rotating freely and playing a positioning role.

[0033] In addition, the present invention also provides a washing machine, which has the quick disassembly and assembly device described in any of the above embodiments.

[0034] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
