Problems solved by technology

[0002] With the increasing demand for washing machines in the market, the requirements for the output and assembly quality of washing machines are getting higher and higher. The assembly workers on the assembly line have complaints about the installation of adjustable feet. The existing washing machine feet and washing machines are assembled in The sheet metal parts of the bottom plate of the cabinet are provided with flanging holes, and tapping machines are used on the basis of the flanging. Due to the low precision of the tapping machine, the tapping of the sheet metal parts of the bottom plate is rough, and the lock on the foot bolts The assembly of the tight nut is very tight. Under the premise of ensuring the output and quality, the assembly staff can only desperately assemble it by hand, which is time-consuming and laborious.
And the height of the flange is limited by the size of the flange hole and the thickness of the material. The foot bolts of the washing machine usually use M10 screw columns. The pitch of the M10 screw column threads is 1.5mm. Height The overall height generally does not exceed 3mm, and the number of thread turns in the threaded hole is small, so it is very difficult to assemble the M10 screw column with the sheet metal parts of the bottom plate, and it cannot be guaranteed to be screwed in place, and if the foot is often disassembled and replaced It is easy to cause wrinkle

Embodiment 1

[0041] like image 3 and Figure 4 As shown, this embodiment provides an adjustable foot, including: a support base 7; a bolt 8, one end of which is fixedly connected to the support base 7; an adjusting nut 4, which is threadedly connected to the bolt 8, the adjustment nut 4 is used to adjust the support height of the adjustable foot; the lock nut 5, the lock nut 5 is located on the bolt 8 between the adjustment nut 4 and the support seat 7, through locking The frictional force between the nut 5 and the bolt 8 is used to realize the self-locking of the bolt 8 and ensure the height adjustability of the foot bolt 8 . In the present invention, both the foot bolt 8 and the adjustment nut 4 are standard parts, which have good matching accuracy, can increase the assembly efficiency of the adjustable foot, and reduce the difficulty of assembly. The adjustment nut 4 provided in this embodiment is provided with a The positioning structure for the assembly of the washing machine is di...

Embodiment 2

[0044] This embodiment provides a washing machine. The bottom plate of the washing machine is provided with the adjustable foot according to the present invention, which is used for adjusting the height of the washing machine.

[0045] like Figure 1 to Figure 4 As shown, in this embodiment, the washing machine includes a washing machine bottom plate 1, and a locking hole 2 is opened on the washing machine bottom plate 1 through a stamping process, and the adjusting nut 4 is snapped into the locking hole 2 to realize an adjustable bottom. Assembling of the feet and the washing machine, the assembly of the feet and the washing machine in the prior art is mostly to provide threaded holes on the bottom plate of the washing machine through a tapping machine, and realize the assembly of the washing machine and the feet through the bolts and threaded holes. The bit hole 2 replaces the threaded hole, and realizes the assembly of the foot and the washing machine by means of clamping, ...

Embodiment 3

[0050] In this embodiment, on the basis of the second embodiment, a relief hole communicating with the locking hole is opened on the bottom plate of the washing machine 1, and the adjusting nut can enter into the locking hole through the relief hole.

[0051] Specifically, such as Figure 5 and Figure 6 As shown, a relief hole 3 communicating with the clamping hole 2 is provided on the bottom plate of the washing machine through a stamping process. The relief hole 3 is a circular hole in the cross section of the external adjustment nut 4. The circular hole The aperture is greater than the distance of the longest diagonal line of the adjusting nut 4, so as to ensure that the adjusting nut 4 can freely pass through the relief hole 3, and can be moved and embedded in the locking hole 2 through the relief hole 3. Through the relief hole 3 provided, the adjusting nut 4 can enter the locking hole 2 from the relief hole 3, and does not need to enter the locking hole 2 from the gap ...

Abstract

The invention discloses an adjustable foot. The foot comprises a supporting base, a bolt, an adjusting nut, and a locking nut. One end of the bolt is fixedly connected with the supporting base. The adjusting nut is connected with the other end of the bolt in a threaded mode. The locking nut is arranged on the bolt between the adjusting nut and the supporting base. A positioning structure is arranged on the adjusting nut, and is used for assembly. The positioning structure is positioning clamping slots formed in at least one of the outer wall surfaces of the adjusting nut. The adjusting nut isa hexagon nut. The positioning structure is positioning clamping slots formed in two outer wall surfaces, opposite to each other, of the hexagon nut, or positioning clamping slots formed in the wholeperipheral wall of the periphery of the hexagon nut. The invention also discloses a washing machine with the adjustable foot. A bottom plate of the washing machine is provided with clamping holes, andthe positioning clamping slots of the adjusting nut are clamped inside the clamping holes. Therefore, the assembly of the adjustable foot and the washing machine is realized with high assembly efficiency.
