Description

Technical Field

[0001] This utility model relates to the field of washing machine top plate technology, specifically to a high heat-resistant plastic top plate for washing machines. Background Technology

[0002] The top panel of a washing machine typically refers to a component installed on top of the machine. Its main function is to protect the internal equipment and electrical control components, while also providing an interface for operation. The top panel is usually made of high-quality engineering plastics, a durable and brightly colored material. The design of the top panel is generally coordinated with the overall appearance of the washing machine.

[0003] In the existing technology, the washing machine is connected to the casing by self-tapping screws. However, after long-term use, if the washing machine is damaged, auxiliary tools are needed to loosen the self-tapping screws, which greatly increases the workload and reduces convenience. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high heat-resistant plastic top plate for washing machines. When using the high heat-resistant plastic top plate for washing machines, pressing the moving block causes the clamping rods to move away from each other, thereby releasing the clamping of the extension rod and facilitating the removal of the top plate.

[0005] This utility model provides the following technical solution: a high heat-resistant plastic top plate for a washing machine, comprising: a washing machine, a top plate pluggably connected to the top of the washing machine, placement slots provided at the four corners of the top of the washing machine, a fixed box fixedly connected inside the placement slots, a movable block slidably connected inside the fixed box, the top of the movable block having a trapezoidal structure design, a receiving slot provided at the top of the movable block, mounting seats symmetrically fixedly connected to the top of the movable block, a clamping rod rotatably connected inside the mounting seat, extension rods fixedly connected at the four corners of the bottom of the top plate, and snap-fit ​​balls fixedly connected to the bottom of the extension rods.

[0006] As a preferred embodiment of this utility model, the fixed box is internally fixedly connected with two sets of limiting plates, the moving block is slidably connected between the two sets of limiting plates, the bottom end of the moving block is provided with an irregular groove, and an irregular block is fixedly connected inside the irregular groove.

[0007] As a preferred embodiment of this utility model, a receiving plate is fixedly connected to the bottom of both sides of the movable block, and a spring is fixedly connected to the top of the receiving plate, with the spring extending to the top of the inner side of the fixed box.

[0008] As a preferred embodiment of this utility model, a mounting block is fixedly connected to the bottom of the inner side of the fixing box, and a swing rod is rotatably connected to the top of the mounting block, with the swing rod extending into the interior of the irregular groove.

[0009] As a preferred embodiment of this utility model, the extension rod is symmetrically fixedly connected to the outside of the mounting plate, and the top of the clamping rod is provided with a notch at the position corresponding to the extension rod, so that the snap-fit ​​ball can be used in conjunction with the receiving groove.

[0010] As a preferred embodiment of this utility model, the top plate is composed of a surface layer, an intermediate layer and a bottom layer, with the surface layer located at the top of the top plate, the intermediate layer located at the bottom of the surface layer, and the bottom layer located at the bottom of the intermediate layer.

[0011] As a preferred embodiment of this utility model, the surface layer is a heat-resistant modified PC plastic layer, the middle layer is a nano aerogel heat insulation film, and the bottom layer is a PP substrate with a mesh structure design.

[0012] The beneficial effects of this utility model are as follows: When the top of the swing rod swings to the top of the irregular block, it will generate a pulling force on the moving block, causing the moving block to slide downward inside the fixed box. Then, the inner side wall of the fixed box will squeeze the clamping rod. Subsequently, the notches of the two sets of clamping rods will squeeze the top of the mounting plate, completing the installation of the top plate. When the swing rod moves to the bottom of the irregular block, the spring's extension and retraction energy is released, causing the moving block to return to its original position. Since the top of the moving block is set in an inclined position, the clamping rods are affected by gravity and move away from each other. Then, the wrapping of the extension rod is released, completing the disassembly of the top plate. Attached Figure Description

[0017] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Example:

[0019] like Figures 1 to 3 As shown, a high heat-resistant plastic top plate for a washing machine includes: a washing machine 1; a top plate 2 is pluggably connected to the top of the washing machine 1; placement slots 3 are provided at the four corners of the top of the washing machine 1; a fixing box 4 is fixedly connected inside the placement slot 3; a movable block 5 is slidably connected inside the fixing box 4; the top of the movable block 5 has a trapezoidal structure design; a receiving slot 6 is provided at the top of the movable block 5; mounting bases 7 are symmetrically fixedly connected to the top of the movable block 5; clamping rods 8 are rotatably connected inside the mounting bases 7; extension rods 9 are fixedly connected to the four corners of the bottom of the top plate 2; and locking balls 1 are fixedly connected to the bottom of the extension rods 9. 0. When the washing machine 1 is damaged after long-term use, the top plate 2 needs to be removed for easy inspection of its internal components. By pressing the top plate 2, the extension rod 9 is pressed down simultaneously, which drives the locking ball 10 to descend and contact the moving block 5. The moving block 5 then slides inside the fixing box 4. The inner side wall of the fixing box 4 then squeezes the clamping rod 8. One end of the clamping rod 8 is then limited by the mounting seat 7, causing it to swing inside the mounting seat 7. Then the two sets of clamping rods 8 come closer to each other and wrap around the extension rod 9, thereby fixing the top plate 2.

[0020] In this embodiment, two sets of limiting plates 11 are fixedly connected inside the fixed box 4, and the moving block 5 is slidably connected between the two sets of limiting plates 11. The bottom end of the moving block 5 is provided with an irregular groove 12, and an irregular block 13 is fixedly connected inside the irregular groove 12. Through the design of the two sets of limiting plates 11, the moving block 5 can move along a straight line when sliding outside the fixed box 4, and at the same time the irregular groove 12 and the irregular block 13 move synchronously with the moving block 5.

[0021] In this embodiment, a receiving plate 14 is fixedly connected to the bottom ends of both sides of the movable block 5. A spring 15 is fixedly connected to the top of the receiving plate 14. The spring 15 extends to the top of the inner side of the fixed box 4. A mounting block 16 is fixedly connected to the bottom end of the inner side of the fixed box 4. A swing rod 17 is rotatably connected to the top of the mounting block 16. The swing rod 17 extends into the interior of the irregular groove 12. When the movable block 5 slides, one end of the swing rod 17 is limited by the mounting block 16, causing it to swing with the mounting block 16 as the force point and slide inside the irregular groove 12. When the top of the lever 17 swings to the top of the irregular block 13, it will exert a pulling force on the moving block 5, causing the moving block 5 to slide downward inside the fixed box 4. When the lever 17 moves to the bottom of the irregular block 13, the pulling force on the moving block 5 will be released. At this time, the energy stored in the extension and retraction of the spring 15 will be released, causing the moving block 5 to return to its original position. Then the moving block 5 will slide upward, and the fixed box 4 will release the pressure on the clamping rod 8. Since the top of the moving block 5 is set to be inclined, the clamping rod 8 will move away from each other due to gravity, and then release the wrapping of the extension rod 9.

[0022] In this embodiment, the extension rod 9 is symmetrically fixedly connected to the outside of the mounting plate 18. The top of the clamping rod 8 is provided with a notch at the position corresponding to the extension rod 9. The snap ball 10 is adapted to the receiving groove 6. When the extension rod 9 is lowered, the snap ball 10 will directly enter the interior of the receiving groove 6, and then the notch of the clamping rod 8 will squeeze the top of the mounting plate 18.

[0023] In this embodiment, the top plate 2 is composed of a surface layer 201, an intermediate layer 202, and a bottom layer 203. The surface layer 201 is located at the top of the top plate 2, the intermediate layer 202 is located at the bottom of the surface layer 201, and the bottom layer 203 is located at the bottom of the intermediate layer 202. The surface layer 201 is a heat-resistant modified PC plastic layer, the intermediate layer 202 is a nano-aerogel heat insulation film, and the bottom layer 203 is a PP substrate. The PP substrate has a mesh structure design. The heat-resistant modified PC plastic layer can withstand high-temperature environments greater than 120°C, maintaining structural stability for a long time in the high-temperature steam environment of the washing machine 1, avoiding deformation or softening, and effectively extending the service life of the top plate 2. The nano-aerogel heat insulation film can block the heat conduction of the high-temperature steam of the washing machine 1 to the top cover, reducing surface temperature fluctuation by more than 40%. The PP substrate adopts a mesh structure, which greatly improves the hardness of the top plate 2.

[0024] Implementation Plan: When the washing machine 1 is damaged after long-term use, the top plate 2 needs to be removed for easy inspection of its internal components. By pressing the top plate 2, the extension rod 9 is pressed down simultaneously, which in turn causes the retaining ball 10 to descend and contact the moving block 5. Through the design of two sets of limiting plates 11, the moving block 5 moves in a straight line when sliding outside the fixed box 4. At the same time, the irregular groove 12 and the irregular block 13 move synchronously with the moving block 5. One end of the swing rod 17 is limited by the mounting block 16, causing it to swing with the mounting block 16 as the force point and slide inside the irregular groove 12. When the top of the swing rod 17 swings to the top of the irregular block 13, it will generate a pulling force on the moving block 5, causing the moving block 5 to slide downward inside the fixed box 4. Then, the inner wall of the fixed box 4 will squeeze the clamping rod 8. Then, one end of the clamping rod 8 is limited by the mounting seat 7, causing it to swing inside the mounting seat 7. As the clamping rods 8 approach each other, the notches of the clamping rods 8 press against the top of the mounting plate 18, completing the installation of the top plate 2. By pressing the top plate 2 again, when the swing rod 17 moves to the bottom of the irregular block 13, the tension on the moving block 5 is released. At this time, the stored energy of the spring 15 is released, causing the moving block 5 to reset. Then the moving block 5 slides upward, and the fixing box 4 releases the pressure on the clamping rods 8. Since the top of the moving block 5 is set in an inclined shape, the clamping rods 8 are affected by gravity and move away from each other. Then the wrapping of the extension rod 9 is released, completing the disassembly of the top plate 2. The heat-resistant modified PC plastic layer can withstand high temperature environments greater than 120℃, maintaining structural stability for a long time in the high temperature steam environment of the washing machine 1, avoiding deformation or softening, and effectively extending the service life of the top plate 2. The nano aerogel heat insulation film can block the heat conduction of the high temperature steam of the washing machine 1 to the top cover, reducing surface temperature fluctuation by more than 40%. The PP substrate adopts a mesh structure, which greatly improves the hardness of the top plate 2.
