Description

Technical Field

[0001] This utility model relates to the field of washing machine clutch technology, and in particular to a brake clutch for a washing machine. Background Technology

[0002] The washing machine clutch is an important component of a washing machine, mainly used to connect the washing tub and the motor, enabling the washing tub to rotate under the drive of the motor, thereby completing the washing process. The clutch is usually composed of a clutch housing, a clutch inner sleeve, a clutch spring, a clutch bearing, and a clutch gear. The clutch housing is fixed to the washing machine base, while the clutch inner sleeve is connected to the washing tub. When the motor starts, the clutch gear drives the clutch inner sleeve to rotate, thereby driving the washing tub to rotate.

[0003] Chinese patent document CN217459950U discloses a washing machine clutch housing that is easy to install. It features a pair of connecting blocks fixedly connected to the bottom surfaces of two connecting plates. Each connecting plate has an arc-shaped groove in its middle section.

This mechanism includes two arc-shaped strips and two pairs of connecting pieces. A circular ring is fixedly connected between the two base plates, and two sets of insert rods are fixedly connected to the upper surface of the circular ring. In this invention, the bottom ring and retaining ring are threadedly connected to the circular ring. Rotating the rotating plate causes the upper surface of the rotating plate to align with the bottom surface of the retaining ring, aligning the two limiting grooves. Bolts are used to fix the positions of the two limiting grooves, thus fixing the positions of the bottom ring and retaining ring, preventing loosening, improving stability, and facilitating the replacement of the bottom ring without requiring complete replacement.

The opposite ends of the two screws are rotatably connected to the middle of the side of the two movable plates that are far apart from each other. The two movable plates are located in the inner cavity of the mounting bracket. The front and rear parts of the opposite sides of the two movable plates are rotatably connected with adjusting plates.

The four front and rear adjacent fixing frames are symmetrically arranged. The ends of the four front and rear adjacent fixing frames that are far apart from each other are movably connected to the left and right positions of the bottom of the clutch and brake structure.

[0010] The anti-loosening component includes two rectangular guide posts. The opposite ends of the two rectangular guide posts are rotatably connected to the bottom of the left and right sides of the mounting bracket. The two rectangular guide posts are located directly below the two screws. Pull plates are slidably connected to the outer sides of the two rectangular guide posts. Limiting blocks are fixedly installed on the top of the opposite sides of the two pull plates. Turntables are fixedly installed on the ends of the two screws that are far apart from each other. The opposite sides of the turntables are provided with slots for two matching limiting blocks.

[0011] Preferably, the inner walls of the front and rear positions of the bottom left and right sides of the mounting bracket are slidably connected to limit posts, and the opposite ends of the four adjacent left and right limit posts are fixedly connected to the front and rear parts of the two movable plates on opposite sides.

[0012] Preferably, guide rods are fixedly installed at the bottom positions of the left and right sides of the inner wall of the mounting bracket.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] 1. This utility model provides a brake clutch for a washing machine. Through the cooperation of a moving plate, screws, adjusting plate, sliders, fixing brackets, limiting posts, guide rods, guide blocks, mounting base, and connecting plate, the clutch brake structure can be quickly fixed / disassembled by rotating two screws. When the two screws are rotated, they cause the two moving plates to move closer / away from each other. When the two moving plates move closer, four adjacent sliders move away from each other, causing four adjacent fixing brackets to move, allowing the four fixing brackets to insert into slots on the corresponding connecting plate, thereby fixing the bottom of the clutch brake structure. When the two moving plates move away from each other, the four sliders move in the opposite direction, allowing the four fixing brackets to quickly separate from the corresponding connecting plate, thus achieving rapid disassembly of the clutch brake structure. This design is highly practical and improves the quick maintainability of the brake clutch.

[0019] 2. This utility model provides a brake clutch for a washing machine. Through the cooperation of rectangular guide posts, pull plates, limit blocks, turntables, locking blocks, and springs, two screws can be locked in place by two limit blocks, preventing them from being affected by the vibrations of the washing machine. When it is necessary to rotate the two screws, the two pull plates can be moved outwards, causing them to move away from each other and compress the corresponding springs. At this time, the two limit blocks will move away from their corresponding locking slots. Then, rotating the two rectangular guide posts will move the two pull plates away from the front of the two turntables, avoiding interference with the screw adjustment. The structure is simple, highly practical, and also improves the stability of the brake clutch installation. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-5 As shown, a brake clutch for a washing machine includes a π-shaped mounting bracket 1 and a clutch braking structure 4. The left and right sides of the inner wall of the mounting bracket 1 are movably connected to a limiting and fixing component 2. The four corners of the bottom of the clutch braking structure 4 are movably connected to the middle of the limiting and fixing component 2. The bottom of the left and right sides of the mounting bracket 1 is movably connected to an anti-loosening component 3.

[0028] The limiting and fixing assembly 2 includes two movable plates 21. The inner walls of the middle position of the bottom of the left and right sides of the mounting frame 1 are threaded with screws 22. The opposite ends of the two screws 22 are rotatably connected to the middle of the side of the two movable plates 21 that is away from each other. The two movable plates 21 are located in the inner cavity of the mounting frame 1. The front and rear parts of the opposite sides of the two movable plates 21 are rotatably connected with adjusting plates 23. The opposite ends of the four left and right adjacent adjusting plates 23 are rotatably connected with sliders 24. The upper ends of the four sliders 24 are fixedly installed with L-shaped fixing frames 25. The four front and rear adjacent fixing frames 25 are symmetrically arranged. The ends of the four front and rear adjacent fixing frames 25 that are away from each other are movably connected to the left and right positions of the bottom of the clutch braking structure 4.

[0029] The anti-loosening component 3 includes two rectangular guide posts 31. The opposite ends of the two rectangular guide posts 31 are rotatably connected to the bottom of the left and right sides of the mounting bracket 1. The two rectangular guide posts 31 are located directly below the two screws 22. Pull plates 32 are slidably connected to the outer sides of the two rectangular guide posts 31. Limiting blocks 33 are fixedly installed on the top of the opposite sides of the two pull plates 32. Turntables 34 are fixedly installed on the ends of the two screws 22 that are far apart from each other. The opposite sides of the turntables 34 are provided with slots for two matching limiting blocks 33.

[0030] The clutch brake structure 4 can be quickly fixed / disassembled by rotating the two screws 22 using the limiting and fixing assembly 2. When the two screws 22 are rotated, they will cause the two moving plates 21 to move closer / away from each other. When the two moving plates 21 move closer, the four adjacent sliders 24 move away from each other and drive the four adjacent fixing brackets 25 to move, so that the four fixing brackets 25 can be inserted into the slots on the corresponding connecting plates 42, thereby fixing the bottom of the clutch brake structure 4. When the two moving plates 21 move away from each other, the four sliders 24 move in the opposite direction, so that the four fixing brackets 25 can be quickly separated from the corresponding connecting plates 42, thereby realizing the quick disassembly of the clutch brake structure 4. It is highly practical and also improves the quick maintenance of the brake clutch. The two screws 22 can be locked by the two limiting blocks 33 using the anti-loosening assembly 3 to prevent them from being affected by the vibration of the washing machine. When it is necessary to rotate the two screws 22, the two pull plates 32 can be moved outward to move them away from each other and squeeze the corresponding springs 36. At this time, the two limit blocks 33 will move away from the corresponding slots. Then, rotate the two rectangular guide posts 31 to move the two pull plates 32 away from the front side of the two turntables 34. This can avoid affecting the adjustment of the screws 22. The structure is simple, practical, and improves the stability of the brake clutch installation.

[0031] like Figure 5 As shown, the inner walls of the front and rear positions of the bottom left and right sides of the mounting bracket 1 are slidably connected to limit posts 26, and the opposite ends of the four adjacent left and right limit posts 26 are fixedly connected to the front and rear parts of the two moving plates 21 on opposite sides.

[0032] The setting of the limiting post 26 has a limiting effect on the movement of the moving plate 21.

[0033] like Figure 3 and Figure 5 As shown, guide rods 27 are fixedly installed at the bottom of the left and right sides of the inner wall of the mounting bracket 1. The two guide rods 27 are located directly below the four sliders 24. Guide blocks 28 are fixedly installed at the lower ends of the four sliders 24. The inner walls of the four adjacent guide blocks 28 are slidably connected to the outer walls of the two guide rods 27.

[0034] The guide rod 27 has a limiting and guiding effect on the movement of the slider 24.

[0035] like Figure 3 and Figure 4 As shown, the lower end of the clutch braking structure 4 is fixedly mounted on the base 41, and the four corners of the lower end of the base 41 are fixedly mounted with connecting plates 42. The opposite sides of the four adjacent front and rear connecting plates 42 are provided with slots for four matching fixing brackets 25.

[0036] When the two movable plates 21 approach each other, the four adjacent sliders 24 move away from each other and drive the four adjacent fixed brackets 25 to move, so that the four fixed brackets 25 can be inserted into the slots on the corresponding connecting plates 42, thereby fixing the bottom of the clutch braking structure 4.

[0037] like Figure 5 As shown, each of the two rectangular guide posts 31 has a locking block 35 fixedly installed at one end away from each other. Each of the two rectangular guide posts 31 has a spring 36 movably sleeved on one side away from each other on the outer side. The opposite ends of the two springs 36 are fixedly connected to the bottom of the opposite side of the two pull plates 32. The opposite ends of the two springs 36 are fixedly connected to the opposite sides of the two locking blocks 35.

[0038] When the user manually operates the pull plate 32 to engage or disengage the limit block 33 from the slot of the turntable 34, the spring 36 provides a reverse restoring force. This helps to automatically return the pull plate 32 and its limit block 33 to their initial position after the user releases the pull plate 32, preparing it for the next operation.

[0039] like Figure 4 As shown, a through hole is provided at the lower middle part of the mounting bracket 1, and the outer wall of the output shaft of the clutch braking structure 4 is movably sleeved with the inner wall of the through hole.

[0040] The through hole at the lower end of the mounting bracket 1 allows the output shaft of the clutch brake structure 4 to pass through, thus enabling its function.

[0041] like Figure 1 and Figure 3 As shown, mounting holes are fixedly installed at the four corners of the upper end of the mounting bracket 1.

[0042] The mounting holes at the upper end of the mounting bracket 1 are used to fix the entire brake clutch to the washing machine. The mounting bracket 1 and the clutch brake structure 4 together form the brake clutch. When the clutch brake structure 4 needs to be maintained, the two can be quickly separated by the limiting and fixing component 2, which is highly practical.

[0043] The working principle of this utility model: The clutch braking structure 4 is an existing mechanism and will not be elaborated further. The mounting bracket 1 and the clutch braking structure 4 together form the brake clutch. The mounting bracket 1 is generally installed at the bottom of the washing machine through its fixing holes. When maintenance or replacement of the brake clutch is required, the clutch braking structure 4 can be removed. The two pull plates 32 are moved outward, causing them to move away from each other and compress the corresponding springs 36. At this time, the two limit blocks 33 will move away from their corresponding slots. Then, the two rectangular guide posts 31 are rotated, causing the two pull plates 32 to move away from the front of the two turntables 34, thus avoiding affecting the adjustment of the screw 22. Secondly, after the clutch braking structure 4 is fixed, the rectangular guide posts 31 and the limit blocks 33 are reset. The mutual cooperation between the two limit blocks 33 and the two slots can prevent the two screws 22 from loosening when the washing machine vibrates, thus improving the stability of the brake clutch installation.

[0044] Subsequently, when the two screws 22 are rotated, they will cause the two moving plates 21 to move away from each other. At this time, the four adjusting plates 23 will rotate around the two moving plates 21 and pull the four sliders 24 to move, so that the four adjacent sliders 24 move closer to each other and drive the four adjacent fixed brackets 25 to move. This allows the four fixed brackets 25 to quickly separate from the corresponding connecting plates 42, thereby realizing the quick disassembly of the clutch braking structure 4. Secondly, the fixing of the clutch braking structure 4 is similar to the above steps. It is only necessary to rotate the two screws 22 to bring the two moving plates 21 closer to each other, which improves the quick maintainability of the brake clutch.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
