Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0031] The washing drum of a washing machine will vibrate violently during operation, so the washing drum is usually supported in the washing machine housing by elastic struts, and the elasticity of the elastic struts is used to absorb the vibrations generated during the operation of the washing drum, thereby reducing the vibrations of the washing machine and protecting the washing drum. The connection between the traditional washing drum and the elastic struts is generally locked by bolts and nuts. However, the high-frequency vibrations generated during the operation of the washing drum can easily cause the nuts to loosen and fall off, eventually causing the connection between the elastic struts and the washing drum to lose its fixation, resulting in the problem of washing machine failure.

[0032] In order to overcome the above technical problems, refer to Figure 1-3 This embodiment provides a connecting nail assembly that can be used in a washing machine to connect a washing drum 4 and an elastic support 5.

[0033] The connecting nail assembly of this embodiment includes a column 1, a front baffle 3 and a lifting spring 2. Specifically, the column 1 has a relative head end and a tail end, and the tail end is provided with a tail baffle 11; a accommodating cavity 12 penetrating the tail end is provided in the column 1, and a side opening 13 connected to the accommodating cavity 12 is provided on the side wall; the front baffle 3 can be movably installed in the accommodating cavity 12, and the front baffle 3 can be moved and adjusted in the axial direction of the column 1, and the front baffle 3 has a baffle arm 32 extending from the side opening 13; the lifting spring 2 is arranged in the accommodating cavity 12 and abuts against the front baffle 3, so as to push the front baffle 3 to move toward the tail end.

[0034] Based on the connecting nail assembly of the present embodiment, an axially extending accommodating cavity 12 is provided in the column 1, and a side opening 13 is provided on the side wall. A front baffle 3 is installed in the accommodating cavity 12, and the front baffle 3 has a baffle arm 32 extending from the side opening 13. At the same time, a lifting spring 2 that can push the front baffle 3 is also provided in the accommodating cavity 12. When the connecting nail assembly of the utility model is used for connection, under the elastic force of the lifting spring 2, the front baffle 3 and the tail baffle 11 of the column 1 respectively abut against the two sides of the connected structure to limit the column 1 from falling off the connected structure, and the front baffle 3 and the lifting spring 2 can always be confined in the accommodating cavity 12 of the column 1, and there is no problem of loose threads, which has the advantage of good connection stability.

[0035] When used in a washing machine to connect the washing drum 4 with the elastic support 5, refer to Figure 4-5 The column 1 passes through the first connecting rib 41, the second connecting rib 42 and the elastic support 5 located between the first connecting rib 41 and the second connecting rib 42 on the washing drum 4, and the front baffle 3 and the tail baffle 11 respectively abut the first connecting rib 41 and the second connecting rib 42, thereby limiting the column 1 from falling off from the connection structure between the washing drum 4 and the elastic support 5, and maintaining a reliable connection between the washing drum 4 and the elastic support 5; and even if the washing drum 4 transmits vibration to the connecting nail assembly during operation, the front baffle 3 and the lifting spring 2 will not be at risk of falling off due to vibration, thereby solving the problem of failure of the connection between the elastic support 5 and the washing drum 4 and malfunction of the washing machine due to loose threads in the traditional connection structure.

[0036] In one embodiment, referring to Figure 2 The side wall of the column 1 is circumferentially spaced with a plurality of side openings 13, the front baffle 3 includes a base plate 31 and a plurality of baffle arms 32 connected to the periphery of the base plate 31, the base plate 31 is located in the accommodating cavity 12, and each side opening 13 corresponds to a baffle arm 32 extending therefrom.

[0037] After installation, a plurality of retaining arms 32 extend from the circumference of the column 1 , which can provide support and limitation from multiple directions, improve the anti-separation capability, and enhance the reliability of the installation of the column 1 .

[0038] In one embodiment, the blocking arm 32 can swing relative to the base plate 31 between a first extreme position and a second extreme position. In the first extreme position, the blocking arm 32 is flush with the base plate 31, and the blocking arm 32 extends out of the side opening 13; in the second extreme position, the blocking arm 32 is inclined toward the tail end relative to the base plate 31, and the blocking arm 32 is retracted into the side opening 13.

[0039] Based on the rotatable function of the blocking arm 32, it is very convenient to insert the front blocking piece 3 into the cavity of the column 1 during installation. Specifically, the blocking arm 32 is connected to the base plate 31 through a rotatable mechanism, allowing the blocking arm 32 to swing between the first extreme position and the second extreme position. In the second extreme position, the blocking arm 32 is tilted toward the rear end relative to the base plate 31, so that the blocking arm 32 can be recovered into the side opening 13, avoiding interference between the blocking arm 32 and the column 1 during installation. In the first extreme position, the blocking arm 32 is flush with the base plate 31, and the blocking arm 32 is completely extended from the side opening 13. When the connecting nail assembly is installed, the blocking arm 32 is in this position to ensure that it can firmly limit the movement of the column 1.

[0040] During installation, first insert the column 1 through the connected structure so that the rear baffle 11 of the column 1 abuts against the connected structure, and then insert the lifting spring 2 and the front baffle into the accommodating cavity 12 from the rear end of the column 1. Based on the rotatable function of the baffle arm 32, the front baffle can be smoothly inserted, and other tools such as a screwdriver can be used to push the insertion process; after the front baffle moves to the other side of the connected structure, each baffle arm 32 automatically rotates and opens toward the second extreme position and extends from the side opening 13 of the column 1; thereafter, the thrust on the front baffle is canceled, and the lifting spring 2 automatically pushes the front baffle to the connected structure to tighten it, thereby completing the installation process of the connecting nail assembly.

[0041] In one embodiment, referring to Figure 3 A bending groove 33 is provided on the side of the connection between the substrate 31 and the blocking arm 32 facing the tail end, and based on the bending groove 33, the blocking arm 32 can swing between the first extreme position and the second extreme position relative to the substrate 31.

[0042] Specifically, the base plate 31 and the blocking arm 32 can adopt an integral die-casting structure, and then a bending groove 33 is formed at the connection between the base plate 31 and the blocking arm 32 by stamping or other means. The bending groove 33 is preferably an inverted triangular groove, so that the blocking arm 32 can be easily rotated and tightened relative to the base plate 31 at the bending groove 33 toward the first limit position during installation, and automatically restore to the second limit position based on the elastic recovery ability of the material itself after installation to achieve the limit function. Therefore, the setting of the bending groove 33 is conducive to the smooth installation of the base plate 31 during installation.

[0043] Based on the design of the bending groove 33 , the difficulty of rotating the barrier arm 32 can be reduced during installation, so the material of the barrier arm 32 can be thickened to improve the pressure-bearing capacity of the barrier arm 32 .

[0044] In one embodiment, referring to Figure 3The front baffle 3 also includes a support plate 34, which is fixedly connected to the side of the base plate 31 facing away from the tail end, and the size of the support plate 34 is larger than the size of the base plate 31. In the first extreme position, the baffle arm 32 abuts against the support plate 34.

[0045] In the first extreme position, the barrier arm 32 is fully opened, and the portion of the barrier arm 32 close to the bending groove 33 abuts against the support plate 34. This design ensures that the barrier arm 32 will not deflect excessively when opened, and also provides a stable support point for the barrier arm 32.

[0046] In one embodiment, the size of the support plate 34 is adapted to the inner diameter of the accommodating cavity 12 , and the axial movement of the front baffle 3 in the accommodating cavity 12 is guided by the support plate 34 .

[0047] The installation of the front baffle 3 is guided by the support plate 34 . This design significantly enhances the guidance and stability of the axial movement of the front baffle 3 in the accommodating cavity 12 .

[0048] In one embodiment, a threaded column 341 is provided on the support plate 34 , and a through hole is correspondingly provided on the base plate 31 . The threaded column 341 passes through the through hole and is connected to the nut 35 , and the base plate 31 is fixed to the support plate 34 through the nut 35 .

[0049] By providing a threaded column 341 on the support plate 34 and providing a corresponding through hole on the base plate 31, and then fixing the base plate 31 on the support plate 34 using a nut 35, this design further enhances the structural stability and installation reliability of the front baffle 3. Preferably, after tightening the nut 35, the nut 35 and the threaded column 341 can be fixed by electric welding to prevent the nut 35 from loosening.

[0050] In one embodiment, the head end is in a pointed cone shape.

[0051] The head end of the column 1 is configured to be in a pointed cone shape, so as to facilitate smooth insertion of the column 1 into the connecting hole of the connected structure.

[0052] On the other hand, refer to Figure 4-5 The present embodiment further provides an installation structure of a washing drum 4, comprising a washing drum 4, an elastic support 5 and the above-mentioned connecting nail assembly, wherein the outer wall of the washing drum 4 is provided with a first parallel connecting rib plate 41 and a second connecting rib plate 42, the elastic support 5 has a connecting head 51 which can be placed between the first connecting rib plate 41 and the second connecting rib plate 42, the connecting nail assembly penetrates the first connecting rib plate 41, the connecting head 51 and the second connecting rib plate 42, the tail baffle 11 of the connecting nail assembly abuts against the first connecting rib plate 41, and the baffle arm 32 abuts against the second connecting rib plate 42.

[0053] Similarly, based on the connecting nail assembly of this embodiment, the installation structure of the washing drum 4 of this embodiment has the advantage of good connection reliability.

[0054] During installation, first place the connecting head 51 between the first connecting rib plate 41 and the second connecting rib plate 42, and align the connecting holes of the three, then pass the front end of the column 1 through the connecting holes of the three, and then install the lifting spring 2 and the front baffle, so that the baffle arms 32 of the front baffle pass over the second connecting rib plate 42 and automatically open, release the thrust on the front baffle, so that the lifting spring 2 automatically pushes the front baffle out, keeping the baffle arms 32 tight against the second connecting rib plate 42.

[0055] On the other hand, a washing machine is provided, comprising the installation structure of the washing drum 4 described above.

[0056] Similarly, the washing machine of this embodiment has the advantage of good connection reliability.
