Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to an anti-collision structure for a dish rack. Background Technology

[0002] Chinese Patent Document No. CN119655582A, published on March 21, 2025, discloses a lifting basket, comprising a basket body and a lifting device for raising or lowering the basket body. The lifting device includes a lifter fixed to the basket body and a slide plate slidably mounted on the basket body. The lifter includes a lifting cylinder, a lifting slider, and a limiter. The lifting cylinder is fixed to the basket body and has a track cavity for the slider to slide vertically. On opposite sides of the lifting cylinder are clearance slots and limit slots communicating with the track cavity. The slide plate passes through the clearance slots and is inserted into the lifting slider for fixation. The limiter is movably connected to the lifting slider. When the basket body slides vertically relative to the slide plate to a first position, the limiter retracts into the track cavity to maintain the first position formed by the basket body and the slide plate. When the basket body slides vertically relative to the slide plate to a second position, the limiter engages with the limit slot to maintain the second position formed by the basket body and the slide plate. The main body of the lifting bowl basket slides back and forth on the guide rail via a sliding plate. The sliding plate drives the lifting cylinder to slide back and forth, and the lifting cylinder can move up and down relative to the sliding plate. The lifting cylinder and the guide rail are made of metal. When the lifting cylinder slides back and forth or moves up and down, it may collide with the guide rail, resulting in scratches on the lifting cylinder and the guide rail, and producing abnormal metallic noises.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide a simple, smooth, noiseless, reliable, and practical anti-collision structure for a bowl basket, in order to overcome the shortcomings of the prior art.

[0005] A collision-resistant structure for a bowl basket designed for this purpose includes a bowl basket body, a sliding plate, a lifting cylinder assembly, and a guide rail. The lifting cylinder assembly is fixed to the bowl basket body, and the sliding plate is relatively slidably mounted on the bowl basket body. The bowl basket body is horizontally mounted on the guide rail via the sliding plate. The characteristic feature is that the lifting cylinder assembly is provided with a collision-resistant friction strip, which is located between the lifting cylinder assembly and the guide rail.

[0006] The anti-collision friction strip has an arc-shaped surface on the side facing the guide rail.

[0007] The anti-collision friction strip is close to or in contact with the guide rail.

[0008] The anti-collision friction strips are made of POM plastic.

[0009] The anti-collision friction strips and lifting cylinder assembly are set vertically, while the guide rail is set horizontally.

[0010] The lifting cylinder assembly is equipped with buckles, and the anti-collision friction strip is equipped with fasteners. The buckles and fasteners engage with each other.

[0011] The lifting cylinder assembly is provided with a mounting groove, and the anti-collision friction strip is installed on the mounting groove.

[0012] The lifting cylinder assembly is provided with limiting edges, which are located on both sides of the mounting groove. The anti-collision friction strip is provided with limiting grooves on both sides, and the limiting edges are engaged in the corresponding limiting grooves.

[0013] The lifting cylinder assembly is provided with a slot, and the main body of the bowl basket is provided with a crossbar. The crossbar is locked in the slot so that the lifting cylinder assembly is fixed to the main body of the bowl basket.

[0014] The skateboard has a guide opening, and the main body of the bowl basket has a vertical rod that is installed on the guide opening.

[0015] The lifting cylinder assembly has a slider that moves up and down inside. The slider has a slot. The lifting cylinder assembly has a clearance groove on one side. The slide plate has an insert edge that passes through the clearance groove and inserts into the slot, so that the lifting cylinder assembly can move up and down on the slide plate.

[0016] The anti-collision structure of this utility model's bowl basket is achieved by setting anti-collision friction strips on the lifting cylinder assembly. The anti-collision friction strips are located between the lifting cylinder assembly and the guide rail, so that the lifting cylinder assembly will not directly collide with the guide rail when sliding back and forth or lifting up and down. Instead, the anti-collision friction strips will only come into contact with and rub against the guide rail, so that the lifting cylinder and the guide rail will not be scratched or produce any metallic noise. Moreover, it makes the back-and-forth dragging and up-and-down lifting of the bowl basket body smoother. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-9 The anti-collision structure of this bowl basket includes a bowl basket body 1, a sliding plate 2, a lifting cylinder assembly 3, and a guide rail 4. The lifting cylinder assembly 3 is fixed on the bowl basket body 1. The sliding plate 2 is slidably mounted on the bowl basket body 1. The bowl basket body 1 is horizontally mounted on the guide rail 4 via the sliding plate 2. The lifting cylinder assembly 3 is provided with an anti-collision friction strip 5, which is located between the lifting cylinder assembly 3 and the guide rail 4. The anti-collision friction strip 5 can prevent the lifting cylinder assembly 3 from directly colliding with the guide rail 4 when it moves back and forth or lifts up and down, and makes the back-and-forth sliding and up-and-down lifting of the bowl basket body 1 smoother. The sliding plate 2, the lifting cylinder assembly 3, and the guide rail 4 are located on the left and right sides of the bowl basket body 1, respectively.

[0028] The anti-collision friction strip 5 has an arc-shaped surface 6 on the side facing the guide rail 4. The arc-shaped surface 6 makes the contact area between the anti-collision friction strip 5 and the guide rail 4 small, thereby reducing the friction surface and reducing the friction generated when the anti-collision friction strip 5 contacts the guide rail 4, further improving the smoothness of the bowl basket body 1 sliding back and forth and lifting up and down.

[0029] The anti-collision friction strip 5 is close to or in contact with the guide rail 4.

[0030] The anti-collision friction strip is made of POM plastic, which has self-lubricating properties, that is, it has a lubricating effect, which can reduce the friction between the anti-collision friction strip 5 and the guide rail 4, while also being friction-resistant and low-noise.

[0031] The lifting cylinder 23 and the guide rail 4 are made of metal.

[0032] The anti-collision friction strip 5 and the lifting cylinder assembly 3 are vertically arranged, while the guide rail 4 is horizontally arranged. The anti-collision friction strip 5, the lifting cylinder assembly 3, and the guide rail 4 are arranged perpendicularly to each other, so that the anti-collision friction strip 5 will always play an anti-collision role when the lifting cylinder assembly 3 slides back and forth and moves up and down.

[0033] The bottom of the lifting cylinder assembly 3 is provided with a buckle 7, and the bottom of the anti-collision friction strip 5 is provided with a buckle 8. The buckle 7 and the buckle 8 are engaged with each other, so that the anti-collision friction strip 5 is positioned vertically on the lifting cylinder assembly 3, which can prevent the anti-collision friction strip 5 from moving vertically.

[0034] The lifting cylinder assembly 3 is provided with an installation groove 9, and the anti-collision friction strip 5 is limited and installed on the installation groove 9.

[0035] The lifting cylinder assembly 3 is provided with limiting edges 10, which are located on both sides of the mounting groove 9. The anti-collision friction strip 5 is provided with limiting grooves 11 on both sides. The limiting edges 10 are inserted into the corresponding limiting grooves 11, so that the anti-collision friction strip 5 is positioned on the lifting cylinder assembly 3 in all directions, which can prevent the anti-collision friction strip 5 from moving in all directions. The cross-section of the anti-collision friction strip 5 is I-shaped.

[0036] The bottom of the lifting cylinder assembly 3 is provided with a positioning notch 20, and the bottom of the anti-collision friction strip 5 is provided with a positioning edge 21, which is engaged with the positioning notch 20.

[0037] The top of the lifting cylinder assembly 3 is provided with a slot 12, and the main body of the bowl basket 1 is provided with a crossbar 13. The crossbar 13 is locked in the slot 12 so that the lifting cylinder assembly 3 is fixed on the main body of the bowl basket 1.

[0038] The skateboard 2 has a guide opening 14 at one end, and the main body of the bowl basket 1 has a vertical rod 15. The vertical rod 15 is installed on the guide opening 14 so that the skateboard 2 is relatively raised and lowered and slidably mounted on the main body of the bowl basket 1. Pulling the main body of the bowl basket 1 up and down causes the main body of the bowl basket 1 to move up and down along the guide opening 14 via the vertical rod 15, thereby adjusting the up and down position of the main body of the bowl basket 1.

[0039] The skateboard 2 is equipped with sliding wheels 22. When the main body of the basket 1 is dragged back and forth, the main body of the basket 1 drives the skateboard 2 to slide back and forth on the guide rail 4 through the sliding wheels 22, so as to adjust the front and back position of the main body of the basket 1.

[0040] The lifting cylinder assembly 3 has a slider 16 that moves up and down inside. The slider 16 has a slot 17. The lifting cylinder assembly 3 has a clearance groove 18 on one side. The slide plate 2 has an insertion edge 19 on the other end. The insertion edge 19 passes through the clearance groove 18 and is inserted into the slot 17 so that the lifting cylinder assembly 3 moves up and down on the slide plate 2. When the lifting cylinder assembly 3 moves up and down, the slider 16 moves up and down relative to the lifting cylinder assembly 3.

[0041] The lifting cylinder assembly 3 includes a lifting cylinder 23, an upper plug 24, and a lower plug 25. The upper plug 24 and the lower plug 25 are respectively installed at the upper and lower ends of the lifting cylinder 23. The mounting groove 9, the limiting edge 10, and the clearance groove 18 are provided on the lifting cylinder 23. The buckle 7 and the positioning notch 20 are provided on the lower plug 25. The slot 12 is provided on the upper plug 24. The guide rail 4 is installed on both sides of the inner tub of the dishwasher.

[0042] Other structures of the lifting cylinder assembly 3 and the sliding plate 2 can be found in patent CN119655582A.
