Description

Technical Field

[0001] The utility model relates to the technical field of washing machine production and manufacturing, in particular to a washing machine counterweight block with adjustable size. Background Technique

[0002] With the improvement of people's living standards, various types of household appliances have gradually entered the general public's families. Washing machines are widely adopted by families because they save manpower, have good cleanliness, and high laundry efficiency. During the laundry or dehydration process of washing machines, the center of the drum is often not concentric with the axis of the motor installed at the lower part, resulting in excessive swing and vibration of the washing machine during use. Therefore, many washing machines are equipped with counterweight blocks to increase the overall inertia of the washing machine's movement and reduce the vibration amplitude during the operation of the washing machine.

[0003] A patent with the publication number CN216074402U has proposed a washing machine counterweight block with adjustable size. The counterweight block includes a stable counterweight plate, an adjustment plate, fixed ears, and a rotating frame. Six second limits are arranged in a circular array on the side of the stable counterweight plate. The inner side of the second limit is rotatably connected to one end of the rotating frame. The rotating frame has an "I" - shaped structure. The adjustment plate is provided with a first limit. The other end of the rotating frame is rotatably installed inside the first limit. When the rotating frame rotates to the horizontal position, that is, the outer side of the stable counterweight plate contacts the inner side of the adjustment plate, at this time, the counterweight block is in the stretched state. When the rotating frame rotates to the vertical position, the stable counterweight plate is clamped in the fixed limit on the adjustment plate, and at this time, the counterweight block is in the contracted state. That is, the counterweight block can be adjusted in size through the rotating frame. However, when the size of this counterweight block is adjusted, it is not stable enough, the size of the counterweight block is relatively limited, and the adjustment range is relatively small, reducing the adjustment range of the counterweight block. In view of the above problems, we propose an improved and upgraded washing machine counterweight block with adjustable size. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a washing machine counterweight block with adjustable size to solve the problems raised in the above background technique.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] Design a washing machine counterweight block with adjustable size, including a first counterweight block and a second counterweight block. A threaded knob is arranged above the second counterweight block. A threaded rod is arranged on the lower end face of the threaded knob. One end of the threaded rod penetrates through the inside of the second counterweight block and the extending end is threadedly connected to a clamping block. A sealing gasket and a sealing ring are respectively arranged inside the second counterweight block. Limiting frames are arranged on the lower end faces of the first counterweight block and the second counterweight block. A screw rod is arranged inside the limiting frame and one end of the screw rod is fixedly connected to an anti - slip pad. An assembly block is arranged inside the limiting frame.

[0007] Further, mounting holes are provided on the upper end surfaces of the first counterweight block and the second counterweight block, and a limiting groove is formed inside the clamping block.

[0008] Further, threaded rods are provided at both the upper and lower ends of the second counterweight block, and one end of each threaded rod is clamped in the limiting groove.

[0009] Further, a notch is formed inside the second counterweight block, the sealing gasket and the sealing ring are both arranged on the outer wall of the clamping block, and one end of the clamping block is arranged on the notch.

[0010] Further, insertion holes are formed on the outer wall of the second counterweight block, insertion rods are arranged on the outer wall of the first counterweight block, and one end of each insertion rod is clamped in the corresponding insertion hole.

[0011] Further, a sleeve is arranged inside the limiting frame, an anti-slip knob is fixedly connected to one end of the screw rod, and the screw rod is in threaded connection with the inside of the sleeve.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Components such as a clamping block, a threaded knob, a threaded rod, a sealing gasket, a sealing ring, and an insertion rod are arranged inside the device of the present utility model. By rotating the upper and lower threaded knobs, the threaded rods are disengaged from the limiting grooves on the clamping block. Then, when the clamping block is clamped with the notch by using the internal sealing gasket and sealing ring, it is relatively sealed. At the same time, by using the clamping connection between the insertion rods and the insertion holes, the sizes of the first counterweight block and the second counterweight block can be adjusted, the applicable range is increased, and the structure is simple.

[0014] 2. Components such as a limiting frame, a counterweight block, an anti-slip knob, a screw rod, and an anti-slip pad are arranged inside the device of the present utility model. By placing two assembly blocks on the limiting frame and then rotating the anti-slip knob to drive the screw rod to rotate inside the sleeve, the anti-slip pad is driven to press and fix the assembly blocks, which is convenient for increasing the counterweight block when using washing machines with different powers, thereby improving the use stability of the washing machine.

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figure 1 - Figure 4 shown, the design of an adjustable washing machine counterweight block provided in this embodiment includes a first counterweight block 1 and a second counterweight block 2. A threaded knob 3 is provided above the second counterweight block 2. A threaded rod 8 is provided on the lower end surface of the threaded knob 3. One end of the threaded rod 8 penetrates through the inside of the second counterweight block 2 and the extending end is threadedly connected to the clamping block 7. A sealing gasket 9 and a sealing ring 10 are respectively provided inside the second counterweight block 2. Limiting frames 6 are provided on the lower end surfaces of both the first counterweight block 1 and the second counterweight block 2. A screw rod 17 is provided inside the limiting frame 6 and an anti-slip pad 18 is fixedly connected to one end of the screw rod 17. An assembly block 5 is provided inside the limiting frame 6.

[0024] Preferably, mounting holes 13 are provided on the upper end surfaces of both the first counterweight block 1 and the second counterweight block 2. A limiting groove 12 is opened inside the clamping block 7, which is convenient for the threaded rod 8 to fix the clamping block 7 inside the second counterweight block 2. Threaded rods 8 are provided at both the upper and lower ends of the second counterweight block 2, and one end of the threaded rod 8 is clamped in the limiting groove 12, which is convenient for fixing the first counterweight block 1 and the second counterweight block 2.

[0025] Preferably, a notch 11 is formed inside the second counterweight block 2. The sealing gasket 9 and the sealing ring 10 are both arranged on the outer wall of the clamping block 7. One end of the clamping block 7 is arranged on the notch 11, which is convenient for effectively sealing when connecting the clamping block 7 with the notch 11 inside the second counterweight block 2. A jack 14 is formed on the outer wall of the second counterweight block 2. An insertion rod 4 is arranged on the outer wall of the first counterweight block 1, and one end of the insertion rod 4 is clamped in the jack 14, which is convenient for stably clamping the first counterweight block 1 and the second counterweight block 2. A sleeve 15 is arranged inside the limiting frame 6. One end of the screw rod 17 is fixedly connected with an anti-slip knob 16.
