Detailed implementation mode

[0017] Refer to Figures 1 to 4 As shown, the present utility model provides a washing machine anti-pinch safety door cover, including: a fixed plate 1 and a door cover plate 6. An activity groove is opened on the side surface of the fixed plate 1, a buffer groove 2 is opened on the side surface of the activity groove, and a fastening plate 5 is slidably connected in the buffer groove 2 through a main spring. A limit rod 3 is fixedly connected in the buffer groove 2 through a mounting plate 12. A limit block 4 is correspondingly connected to the position of the limit rod 3 on the surface of the fastening plate 5. The limit block 4 is slidably connected to the limit rod 3 through a opened limit groove. At the same time, the door cover plate 6 is rotatably connected in the activity groove through a bearing. Guide grooves 13 are symmetrically opened on both side surfaces of the activity groove, and guide rods 14 are fixedly connected in the guide grooves 13. A main slider 8 is slidably connected in the guide grooves 13 through the guide rods 14. A cross bar 7 is fixedly connected to the side surface of the main slider 8. A weight reduction groove 9 is opened on the lower surface of the door cover plate 6. An observation port is opened at the top of the weight reduction groove 9. An observation plate 10 is fixedly connected in the observation port. An auxiliary groove 11 is opened on the side of the observation port away from the fixed plate 1. At the same time, an anti-slip pad 15 is fixedly connected to the top of the auxiliary groove 11.

[0018] In this embodiment, the fixed plate 1 is fixedly connected to the surface of the top plate of the washing machine. After the clothes are put into the washing machine, when the user pulls the door cover plate 6 to rotate and reset it, the edge of the door cover plate 6 will first squeeze the fastening plate 5. The fastening plate 5 moves into the buffer groove 2 and squeezes the corresponding main spring, so that the door cover plate 6 can start to rotate and reset. When the door cover plate 6 rotates to a certain angle, the lower surface of the door cover plate 6 will contact the cross bar 7. Therefore, in the process of the door cover plate 6 continuing to move downward and resetting and closing, the cross bar 7 will stretch the corresponding auxiliary spring through the main slider 8, so that the auxiliary spring changes from the normal state to the stretched state, thereby reducing the closing speed of the door cover plate 6. Moreover, before the door cover plate 6 closes, the cross bar 7 can smoothly stop the door cover plate 6, and it is necessary for the user to press it down again to close, so that the probability of the user's finger being accidentally pinched by the door cover plate 6 can be effectively reduced, and the injury of the user's finger can also be effectively reduced in case of accidental pinching.

[0019] As a preferred implementation mode, the fixed plate 1 is in a rectangular structure. The fixed plate 1 and the activity groove together form a U-shaped structure. The buffer groove 2 opened on the side surface of the activity groove is in a square structure. At the same time, the length of the activity groove is adapted to the width dimension of the door cover plate 6.

[0020] In this embodiment, as Figure 1 and Figure 3, the size of the movable slot is adapted to that of the door cover plate 6, so the stability of the door cover plate 6 during rotation can be effectively enhanced. Moreover, the setting of the fixing plate 1 enables the door cover with the anti-pinch structure to be smoothly installed on the surface of the washing machine.

[0021] As a preferred embodiment, the mounting plate 12 is in a strip-shaped structure. A plurality of limiting rods 3 are fixedly connected to the lower surface of the mounting plate 12 at equal intervals in parallel along the length direction. All the plurality of limiting rods 3 are in a cylindrical structure, and the lower ends of the limiting rods 3 are in a frustum-shaped structure. At the same time, the mounting plate 12 is fixedly connected to the surface of the fixing plate 1 through a buckle.

[0022] In this embodiment, as shown in Figure 2 , Figure 3 and Figure 4 , the setting of the mounting plate 12 enables the limiting rods 3 to be conveniently loaded and unloaded in the movable slot, and the structural setting of the lower ends of the limiting rods 3 can effectively reduce the difficulty of the limiting rods 3 being inserted into the positioning holes.

[0023] As a preferred embodiment, through holes are correspondingly opened at the top of the buffer slot 2 at positions corresponding to the limiting rods 3, positioning holes are correspondingly opened at the bottom of the buffer slot 2 at positions corresponding to the through holes, one end of a main spring is fixedly connected to the side of the buffer slot 2, the other end of the main spring is fixedly connected to a fastening plate 5. At the same time, the fastening plate 5 is in a rectangular structure, and the size of the fastening plate 5 is adapted to that of the buffer slot 2.

[0024] In this embodiment, as shown in Figure 2 and Figure 4 , the fastening plate 5 is slidably connected in the buffer slot 2 through a spring, and the size of the fastening plate 5 is adapted to that of the buffer slot 2, so the stability of the fastening plate 5 during movement can be effectively enhanced. At the same time, the opening of the positioning holes can also enhance the stability of the connection of the limiting rods 3 in the buffer slot 2.

[0025] As a preferred embodiment, the limiting block 4 fixedly connected to the surface of the fastening plate 5 is in a square structure, the size of the limiting slot opened inside the limiting rod 3 is adapted to that of the limiting block 4, and the limiting block 4 and the limiting slot together form a square tube structure. At the same time, a buffer layer is fixedly connected to the side of the fastening plate 5 away from the limiting block 4.

[0026] In this embodiment, as shown in Figure 2 , Figure 3 and Figure 4 , the size of the limiting rod 3 is adapted to that of the limiting slot, so the setting of the limiting block 4 can effectively limit the movement range of the fastening plate 5 and prevent the fastening plate 5 from accidentally detaching from the buffer slot 2. At the same time, the buffer layer is made of soft rubber material, which can assist in increasing the resistance of the fastening plate 5 to the rotation and closing of the door cover plate 6 and reduce the closing speed of the door cover plate 6.

[0027] As a preferred embodiment, the door cover plate 6 has a rectangular structure. The edge of the door cover plate 6 at one end located in the movable groove has an arc structure. The weight-reducing groove 9 formed in the door cover plate 6 has a frustum structure. The observation groove has a square structure. The auxiliary groove 11 formed on the side of the observation groove has a right triangular prism structure. The anti-slip pad 15 fixedly connected to the top of the inner cavity of the auxiliary groove 11 has a strip structure.

[0028] In this embodiment, as Figure 1 and Figure 3 , the settings of the weight-reducing groove 9 and the observation groove can effectively reduce the weight of the door cover plate 6, and then can assist in reducing the closing speed of the door cover plate 6, reducing the injury when the finger is pinched, and at the same time, the anti-slip pad 15 provided in the auxiliary groove 11 can facilitate the user to quickly open the door cover plate 6 and reduce the probability of slipping.

[0029] As a preferred embodiment, the guide groove 13 has a strip structure. The guide rod 14 fixedly connected in the guide groove 13 has a cylindrical structure. The upper end of the guide rod 14 is sleeved with a secondary spring. The two ends of the secondary spring are respectively fixedly connected to the surface of the main slider 8 and the top of the guide groove 13. At the same time, the size of the guide hole formed in the main slider 8 is adapted to that of the guide rod 14. The main slider 8 has a square structure, and the cross bar 7 fixedly connected to the side of the main slider 8 has a cylindrical structure.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 4 , the main slider 8 is slidably connected to the guide rod 14 through the guide hole, which can assist in enhancing the stability of the main slider 8 when moving in the guide groove 13 and prevent the main slider 8 from accidentally disengaging from the guide groove 13. The structural setting of the cross bar 7 can reduce the resistance when the cross bar 7 slides on the surface of the door cover plate 6, ensuring that the door cover plate 6 can push the cross bar 7 to move at any angle, so that the door cover plate 6 can be smoothly closed.

[0031] The anti-pinch safety door cover of the washing machine of the present utility model enables the door cover plate 6 to close at a slower speed through the cooperation of the fixing plate 1, the fastening plate 5, the main slider 8 and the cross bar 7, and requires the user to press down twice to complete the closing, thereby effectively reducing the probability of the user's finger being pinched, and the reduction of the closing speed of the door cover plate 6 can effectively reduce the injury when the user's finger is pinched.
