[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-9 In the embodiment of the utility model, a washing machine drum hanging frame includes a sliding locking seat 7 for buckling and fixing a buffer spring 6; four sliding locking seats 7 are provided, which are respectively installed under the four corners of the mounting frame 8;

[0034] The sliding locking seat 7 comprises a sliding seat 71 with a hanging hole, and the sliding seat 71 is slidably connected to the bottom of the fixed seat 72; a stud 73 is fixed on the inner side below the fixed seat 72, and the stud 73 passes through the through hole below the sliding seat 71 and is locked by a nut.

[0035] By adopting the above technical solution, when fixing the buffer spring 6, first loosen the nut on the stud 73, then slide the sliding seat 71 inward along the fixing seat 72 to the maximum position, at this time, the buffer spring 6 can be easily buckled onto the sliding seat 71; after the spring is buckled, use a wrench or a hand drill to tighten the nut using a socket; in the process of continuous advancement of the nut, the sliding seat 71 moves outward along the fixing seat 72, thereby realizing the tightening of the buffer spring 6; compared with the traditional direct buckling installation method, it saves time and effort.

[0036] As a further explanation of this embodiment, after long-term use, the buffer spring 6 will be stretched as a whole, causing elastic fatigue of the buffer spring 6. At this time, the nut can be further tightened inward to increase the tensile strength of the buffer spring 6, thereby ensuring the shock absorption effect of the washing machine drum and the stability of the lifting.

[0037] The mounting frame 8 includes two transverse fixing plates 81, between which two longitudinal fixing plates 82 are fixed; the longitudinal fixing plates 82 are arranged in a U-shape, and threaded holes are provided at both ends of the longitudinal fixing plates 82 for convenient bolt fixing.

[0038] By adopting the above technical solution, the transverse fixing plate 81 is used to connect and fix the fixing seat 72; the longitudinal fixing plate 82 is fixed to the washing machine shell, thereby realizing the installation of the mounting frame 8 as a whole to the washing machine shell; and also facilitating the connection of the sliding locking seat 7.

[0043] The counterweight block 9 is provided with two countersunk holes, and bolts are arranged in the countersunk holes to be fixedly connected with the outer cylinder rear shell 5 .

[0044] By adopting the above technical solution and setting the counterweight 9, the weight of the outer drum 1 and the outer drum rear shell 5 of the washing machine is increased, ensuring that the shaking of the outer drum 1 and the outer drum rear shell 5 of the washing machine will not be aggravated when the rotating drum 2 rotates, thereby improving the overall quietness of the washing machine.

[0045] The working principle of the present invention is: when fixing the buffer spring 6, first loosen the nut on the stud 73, then slide the sliding seat 71 inward along the fixing seat 72 to the maximum position, at this time, the buffer spring 6 can be easily buckled onto the sliding seat 71; after the spring buckling is completed, use a wrench or a hand drill to tighten the nut using a sleeve; in the process of continuous advancement of the nut, the sliding seat 71 moves outward along the fixing seat 72, thereby realizing the tightening of the buffer spring 6; compared with the traditional direct buckling installation method, it is more time-saving and labor-saving.

[0046] Since the fully automatic drum washing machine is located in the middle of the washing machine shell and a washing machine door is opened in front, the drum needs to be installed by hoisting. By adopting the above technical solution, multiple springs can be used to hoist and fix the washing machine outer drum 1 and the outer drum rear shell 5, thereby ensuring the stability of the drum washing machine during operation.

[0047] The setting of the counterweight block 9 increases the weight of the outer drum 1 and the outer drum rear shell 5 of the washing machine, ensuring that the shaking of the outer drum 1 and the outer drum rear shell 5 of the washing machine will not be aggravated when the rotating drum 2 rotates, thereby improving the overall quietness effect of the washing machine.
