Description

Technical Field

[0001] This utility model relates to dishwasher racks, and more particularly to a rack flipping and limiting mechanism. Background Technology

[0002] Dishwashers typically use dish racks to hold dishes within their washing space. Based on the dish rack's drainage properties, it can both support the dishes and allow water to drip off promptly. In existing technology, dish racks are generally assembled from a fixed frame and a movable frame. For dishes of different sizes and diameters, the movable frame can be flipped to the appropriate position. However, due to the lack of a limiting function for the movable frame, the dishes are easily misaligned or stuck together due to the impact of water during the washing process, thus reducing washing efficiency and cleaning effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a bowl rack flipping and limiting mechanism that is easy to operate and has a reliable limiting function, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A bowl rack flipping and limiting mechanism includes a fixed frame and multiple movable frames. The lower end of each movable frame has a shaft with bent portions at both ends, bending towards the same side. Both ends of the shaft are rotatably connected to the fixed frame. Multiple limiting supports are provided on both sides of the fixed frame, each corresponding to a bent portion. Each limiting support has a receiving groove, and the bent portion is located within the receiving groove. The edge of the fixed frame forms a limiting portion extending into the receiving groove. A limiting groove is formed on one side wall of the receiving groove facing the limiting portion. A first protrusion and a second protrusion are formed on the outer side wall of the bent portion. When the movable frame is flipped, the bent portion enters the receiving groove, the first protrusion engages in the limiting groove, and the second protrusion engages below the limiting portion.

[0006] Preferably, the fixing frame includes two parallel straight rods and a plurality of crossbeams disposed between the two straight rods.

[0007] Preferably, the two ends of the shaft pass through two straight rods respectively, and the shaft and the straight rods are rotatably engaged.

[0008] Preferably, the limiting support is disposed on the outer side wall of the straight rod, and the limiting support protrudes outward from the straight rod.

[0009] Preferably, both the first protrusion and the second protrusion are protrusions with an arc-shaped cross-section, and the limiting groove is a groove with an arc-shaped cross-section.

[0010] Preferably, the vertical height of the second protrusion is greater than the vertical height of the first protrusion.

[0011] Preferably, the edge of the limiting portion is formed with a chamfered portion that abuts against the second protrusion.

[0012] Preferably, the upper end of the movable frame has a rearwardly curved abutment portion.

[0013] In the bowl rack flipping and limiting mechanism disclosed in this utility model, multiple movable frames are sequentially distributed along the length of the fixed frame. Because both ends of the shaft are rotatably connected to the fixed frame, the movable frames can flip relative to the fixed frame around the shaft. Simultaneously, the bent portions at both ends of the shaft bend to the same side. A limiting support is provided at the edge of the fixed frame corresponding to the bent portion, and a receiving groove is provided on the limiting support so that the bent portion can flip into the receiving groove. When the user performs the operation of flipping the movable frame, the first protrusion... The protruding part is engaged in the limiting groove, and the second protruding part is engaged below the limiting part. Because the limiting support is a groove-shaped structure and the limiting part is an outwardly extending structure, the limiting support and the limiting part can undergo slight deformation based on their own elasticity during the process of the bent part entering the receiving groove, thereby reducing the flipping resistance and facilitating the user to perform the flipping operation. In addition, based on the combined action of the limiting groove and the limiting part, both sides of the bent part can be limited at the same time, so the limiting relationship is more reliable and better meets the application requirements.

[0019] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0020] This utility model discloses a bowl rack flipping and limiting mechanism, combined with Figures 1 to 5As shown, it includes a fixed frame 1 and multiple movable frames 2. The lower end of each movable frame 2 is provided with a shaft 20. Both ends of the shaft 20 form bent portions 21 that bend to the same side. Both ends of the shaft 20 are rotatably connected to the fixed frame 1. Multiple limiting supports 10 are provided on both sides of the fixed frame 1. Each limiting support 10 corresponds to one of the bent portions 21. Each limiting support 10 has a receiving groove 11, and the bent portion 21 is disposed within the receiving groove 11. The edge of the fixed frame 1 has a limiting part 12 extending into the receiving groove 11. The receiving groove 11 has a limiting groove 13 on one side wall facing the limiting part 12. The outer side wall of the bent part 21 has a first protrusion 210 and a second protrusion 211 respectively. When the movable frame 2 is flipped, the bent part 21 enters the receiving groove 11. The first protrusion 210 is engaged in the limiting groove 13, and the second protrusion 211 is engaged below the limiting part 12.

[0021] In the above structure, multiple movable frames 2 are sequentially distributed along the length of the fixed frame 1. Since both ends of the shaft 20 are rotatably connected to the fixed frame 1, the movable frame 2 can rotate relative to the fixed frame 1 with the shaft 20 as its axis. Simultaneously, the bent portions 21 at both ends of the shaft 20 bend to the same side. A limiting support 10 is provided at the edge of the fixed frame 1 corresponding to the bent portion 21. The limiting support 10 has a receiving groove 11 so that the bent portion 21 can rotate into the receiving groove 11. When the user performs the operation of rotating the movable frame 2, the first protrusion 210 engages the movable frame. Within the limiting groove 13, the second protrusion 211 is simultaneously engaged below the limiting part 12. Because the limiting support 10 has a groove-shaped structure and the limiting part 12 has an outwardly extending structure, during the process of the bent part 21 entering the receiving groove 11, the limiting support 10 and the limiting part 12 can undergo slight deformation based on their own elasticity, thereby reducing the flipping resistance and facilitating the user to perform the flipping operation. In addition, based on the combined action of the limiting groove 13 and the limiting part 12, both sides of the bent part 21 can be limited simultaneously, thus the limiting relationship is more reliable and better meets the application requirements.

[0022] Regarding the preferred structure of the fixing frame 1, please refer to the embodiment. Figure 2 and Figure 3 The fixing frame 1 includes two parallel straight rods 100 and a plurality of crossbeams 101 disposed between the two straight rods 100.

[0023] The straight rod 100 is a hollow straight rod with a claw 16 at the bottom, which can be used to secure the dish rack to the dish basket of the dishwasher.

[0024] Furthermore, both ends of the shaft 20 pass through two straight rods 100 respectively, and the shaft 20 and the straight rods 100 are rotatably engaged. In this embodiment, the shaft 20 can be rotatably connected to the straight rods 100 through mechanisms such as bushings and bearings.

[0025] In order to give the limiting support 10 a certain degree of elasticity, in this embodiment, the limiting support 10 is provided on the outer side wall of the straight rod 100, and the limiting support 10 protrudes outward from the straight rod 100.

[0026] As a preferred embodiment, both the first protrusion 210 and the second protrusion 211 are protrusions with an arc-shaped cross-section, and the limiting groove 13 is a groove with an arc-shaped cross-section. Further, the edge of the limiting part 12 has a chamfered portion 121 that abuts against the second protrusion 211. This embodiment preferably employs a limiting method where the arc-shaped protrusion and the arc-shaped limiting groove match, and a chamfered portion is correspondingly provided. This structure ensures that the bent part 21 is tightly engaged with the limiting support 10 while appropriately reducing engagement resistance, thereby facilitating the user to flip the movable frame 2.

[0027] Please see Figure 3 The vertical position of the limiting part 12 is slightly higher than that of the limiting groove 13. In order to match the positions of the limiting part 12 and the limiting groove 13, in this embodiment, the vertical height of the second protrusion 211 is greater than that of the first protrusion 210.

[0028] As a preferred embodiment, the upper end of the movable frame 2 is formed with a rearwardly curved abutment portion 22. The abutment portion 22 of the above structure can extend inward toward the plate or bowl, thereby better abutting and engaging with the tableware.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
