[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] See also Figure 1-Figure 7 The lifting bowl basket comprises a bowl basket body 1 and a lifting device for lifting or lowering the bowl basket body 1, wherein the lifting device comprises a lifter fixed on the bowl basket body 1 and a slide plate 2 which is slidably arranged on the bowl basket body 1, wherein the lifter comprises a lifting cylinder 31, a lifting slide block 32 and a stopper 33, wherein the lifting cylinder 31 is fixed on the bowl basket body 1 and is provided with a track cavity 310 for the slide block 32 to be lifted and slidable, wherein the opposite sides of the lifting cylinder 31 are respectively provided with a clearance groove 311 which is connected to the track cavity 310 and a The limit groove 312, the slide plate 2 passes through the air avoidance groove 311 and is inserted into the lifting slide block 32 for fixing, the limiter 33 is movably connected to the lifting slide block 32, when the bowl basket body 1 is lifted and slid relative to the slide plate 2 to the first position, the limiter 33 is received in the track cavity 310 to maintain the first position formed by the bowl basket body 1 and the slide plate 2, when the bowl basket body 1 is lifted and slid relative to the slide plate 2 to the second position, the limiter 33 is clamped on the limit groove 312 to maintain the second position formed by the bowl basket body 1 and the slide plate 2. The structure of the slide plate 2 and the lifter is simpler, and no complex hinge structure is required. When the bowl basket body 1 maintains the lifting and lowering position, it only needs to change the matching position of the limiter 33, and no additional complex locking mechanism is required. The overall structure is simpler, and the cost and assembly cost are lower.

[0022] Specifically, the slide plate 2 and the limiter 33 are respectively located at the head and tail ends of the slider 32, and the assembly of the slide plate 2, the limiter 33 and the slider 32 will not interfere with each other. The head end of the slider 32 is horizontally provided with a slot 321, and the tail end of the slide plate 2 forms a slot 21. The slot 21 passes through the air avoidance groove 311 and is inserted into the slot 21 for fixation. The tail end of the slider 32 is provided with an axial hole 322. The limiter 33 is in a sheet shape, with straight edges 331 on its left and right sides, and concave V-shaped notches 332 on its upper and lower sides. The limiter 33 is rotatably connected in the axial hole 322 and is located on the front side of the slider 32. The air avoidance groove 311 and the limiter groove 312 are opened on the left and right sides of the lifting cylinder 31, and the two are staggered, which also ensures that the slide plate 2 and the limiter 33 will not interfere with each other during the lifting operation.

[0023] Specifically, the limiting groove 312 is close to the lower side of the lifting cylinder 31, and a lever 313 is provided on the front side of the lifting cylinder 31. The lever 313 is adjacent to the limiting groove 312. When the bowl basket body 1 slides to the first position relative to the slide plate 2, the limiter 33 is reset, and its straight edge 331 is retracted into the track cavity 310. The slider 32 abuts against the top of the track cavity 310, and the first position formed by the bowl basket body 1 and the slide plate 2 is maintained under the action of gravity; when the bowl basket body 1 slides to the second position relative to the slide plate 2, the lever 313 moves the V-shaped notch 332 on the lower side of the limiter 33, so that the limiter 33 rotates and the V-shaped notch 332 on the upper side of the limiter 33 and the straight edge 331 on the right side extend out of the limiting groove 312. Under the action of gravity, the limiting groove 312 presses the V-shaped notch 332 to maintain the second position formed by the bowl basket body 1 and the slide plate 2.

[0024] When the basket assembly 1 needs to be raised, the basket assembly 1 only needs to be lifted manually until the stopper 33 follows the slider 32 and falls relatively to the bottom of the lifting cylinder 31. At this time, the lever 313 can move the V-shaped notch 332 on the lower side of the stopper 33, and the V-shaped notch 332 on the upper side of the stopper 33 will then rotate in the direction of the limiting groove 312, and the V-shaped notch 332 on the upper side of the stopper 33 and the straight edge 331 on the right side will extend out of the limiting groove 312. Figure 5 Then, the person can release the bowl basket assembly 1, and the bowl basket assembly 1 is pressed down by gravity. At this time, the limiting groove 312 presses the V-shaped notch 332 located on the upper side of the limiter 33, thereby maintaining the second position formed by the bowl basket body 1 and the slide plate 2, that is, maintaining the bowl basket body 1 rising relative to the slide plate 2, as shown. Figure 6 and Figure 7 shown.

[0025] When it is necessary to lower the basket assembly 1, the basket assembly 1 only needs to be slightly lifted manually, and the limiting groove 312 and the V-shaped notch 332 located on the upper side of the limiter 33 can be released, and the limiter 33 is naturally reset under the action of gravity (due to its special shape, the V-shaped notch 332 located on the upper side of the limiter 33 rotates toward the direction of the escape groove 311 under the action of gravity, and finally keeps the left and right straight edges of the limiter 33 roughly parallel to the up and down direction of the lifting cylinder, which can be understood by technicians in this field) and then stored in the track cavity 310. Then, the basket assembly 1 is released manually, and the basket assembly 1 naturally drops to the lowest position under the action of gravity, thereby maintaining the first position formed by the basket body 1 and the slide 2, that is, maintaining the basket body 1 descending relative to the slide 2, such as Figure 3 and Figure 4 shown.

[0026] The lifting and lowering of the lifting bowl basket is easy to operate, and there is no need to set up a complicated hinge structure and a locking mechanism. The structure is simpler, the cost is lower, and the operation is very simple.

[0027] Furthermore, the shaft hole 322 is an eccentric shaft hole, that is, the center of the shaft hole 322 does not coincide with the central axis of the slider 32, and the shaft hole 322 is offset in the direction of the limit groove 312. This technical solution allows the V-shaped notch 332 located on the upper side of the limiter 33 to rotate faster and extend out of the limit groove 312 when the limit block 33 rotates.

[0028] Furthermore, the first stop protrusion 323 is provided at the head end of the slider 32, and the second stop protrusion 324 is provided at the tail end of the slider 32. The first stop protrusion 323 and the second stop protrusion 324 can respectively abut against the head end and the tail end of the lifting cylinder 310 to achieve the effect of stopping and buffering the impact, and they can also respectively abut against the plug 34 described below to achieve the effect of stopping and buffering the impact, which can be understood by those skilled in the art.

[0029] Furthermore, the lifting cylinder 31 is in the shape of a vertical long cylinder, and its front and rear ends are respectively covered with plugs 34, and the plugs 34 are provided with a clamping groove 341 for clamping with the bowl basket body 1 to fix the lifting cylinder 31. The clamping groove 341 can be directly clamped on the bowl basket body 1, and the operation is very simple.

[0030] Furthermore, the bowl basket body 1 is provided with a guide rib 11, and the slide plate 2 is slidably connected to the guide rib 11, which can be understood by those skilled in the art.

[0031] Furthermore, the lever 313 can be integrally formed with the lifting cylinder 31 by conventional techniques such as injection molding, stamping, and die-casting, and does not need to be separately provided, which helps to reduce assembly costs.

[0032] The above is a preferred embodiment of the present invention, which shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for illustrating the principles of the present invention.
