[0002] A picking trolley, also known as a picking truck, is a means of transport mainly used to load goods when sorting goods.

[0003] There are two main types of existing picking trucks. One type is composed of several cargo frames installed on a frame, and the cargo frames are used to collect the goods. This type of picking truck is mainly used to sort bulk goods and small cargo boxes, and cannot meet the needs of transferring larger cargo boxes; the other type is a flatbed cart, which is mainly used to transport larger cargo boxes, but this type of flatbed cart cannot meet the needs of transferring bulk goods.

[0004] Therefore, at least the above two types of carts are generally prepared in the warehouse, which requires a large space to place the two carts at the same time, and is also inconvenient to use. For example, if bulk goods and large cargo boxes need to be shipped at the same time, two carts need to be used separately, which is time-consuming and labor-intensive; therefore, there is room for improvement. Summary of the invention

[0005] In view of this, an object of the present invention is to provide an adjustable picking trolley.

[0006] In order to solve the above technical problems, the technical solution of the present invention is:

DETAILED DESCRIPTION

[0028] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0029] Example:

[0030] Reference Figure 1 As shown, this embodiment provides an adjustable picking trolley, comprising a base frame 1, a plurality of first rollers 11 arranged at the bottom of the base frame 1, a picking shelf 2 fixedly mounted on the base frame 1 for picking, and a push handle 3 fixedly mounted at one end of the base frame 1. The push handle 3 mainly provides a fulcrum for a person to push the trolley, and a person only needs to push the push handle 3 to push the entire trolley to move, wherein the first roller 11 can be a universal roller.

[0031] In this embodiment, Figure 1 and Figure 4 As shown, the picking rack 2 includes a plurality of vertically fixed brackets 21, and a plurality of horizontally fixed cargo frames 22 between the brackets 21; the cargo frames 22 are arranged at intervals from top to bottom, and the upper ends of the cargo frames 22 are open. Specifically, four brackets 21 can be used, and the cargo frames 22 are rectangular frame structures; the four brackets 21 are fixed at the corners of the cargo frames 22 respectively. The bulk goods or small cargo boxes sorted in this way can be directly placed in the cargo frames 22.

[0032] However, when sorting goods in practice, it is often necessary to sort some loose fragile bottles, such as cans, etc. After these bottles are placed in the cargo frame 22, they are prone to rolling, which may cause collisions between them and easily damage the bottles. Therefore, in this embodiment:

[0033] At least one of the cargo frames 22 is provided with a horizontally arranged shelf 23 for fixing bottles; this embodiment is described by taking the uppermost cargo frame 22 as an example, and the details are as follows:

[0034] The shelf 23 is provided with a plurality of through holes 231 passing through the shelf 23 for bottles to pass through. When placing bottles, the bottles are passed through the through holes 231 until the bottom of the bottles falls to the bottom wall of the cargo frame 22. In this way, the through holes 231 can limit the bottles and prevent them from falling. Since the through holes 231 are arranged at intervals, the bottles will not collide with each other, thereby protecting the bottles.

[0035] Combination Figure 5 and Figure 7 As shown, due to the difference in height of different bottles, in order to adapt to the height of the bottles, in this embodiment, a driving assembly 7 for driving the shelf plate 23 to move along the height direction of the cargo frame 22 is provided between the shelf plate 23 and the cargo frame 22, so as to adjust the height of the shelf plate 23; specifically:

[0036] like Figure 5 As shown, the inner side walls on both sides of the cargo frame 22 are provided with slide grooves 221 extending along the height direction of the cargo frame 22; the side walls at both ends of the shelf plate 23 are fixedly connected with sliders 232 slidably connected to the slide grooves 221; the sliders 232 can be an integrally formed structure with the shelf plate 23, or can be welded to the shelf plate 23; in this way, the sliders 232 can move up and down in the slide grooves 221, thereby driving the shelf plate 23 to move up and down.

[0037] like Figure 5 As shown, the drive assembly 7 includes a screw rod 71 vertically arranged in the slide groove 221, wherein the lower end of the screw rod 71 is rotatably connected to the bottom wall of the slide groove 221; the upper end of the screw rod 71 is movable through the upper end of the cargo frame 22; and the screw rod 71 is threadedly connected to the slider 232; in this way, by rotating the screw rod 71, the slider 232 can be driven to move up and down, and then the shelf plate 23 can be driven to move up and down, thereby achieving the purpose of adjusting the height of the shelf plate 23; in order to facilitate the rotation of the screw rod 71, a hand wheel 72 is fixedly connected to the upper end of the screw rod 71.

[0038] With the above solution, when there is no need to place bottles, the screw rod 71 can be adjusted to move the shelf 23 down to the bottom of the cargo frame 22 so that it fits with the bottom wall of the cargo frame 22. In this way, the shelf 23 will not occupy a large space inside the cargo frame 22, so that more goods can be placed in the cargo frame 22. However, the existence of the perforation 231 may cause some small goods to be stuck in the perforation 231, making it difficult to take out. Therefore, this embodiment is further improved, specifically:

[0039] like Figure 6 As shown, a protrusion 222 that can be inserted into the through hole 231 is fixedly installed on the inner bottom wall of the cargo frame 22 at a position corresponding to the through hole 231; when the bottom wall of the shelf 23 is in contact with the bottom wall of the cargo frame 22, the upper wall of the protrusion 222 is flush with the upper wall of the shelf 23. It can be seen that when the shelf 23 is at the bottom, the protrusion 222 just fills the through hole 231, so that the upper wall of the shelf 23 remains flat, so as to prevent small parts from getting stuck in the through hole 231.

[0040] Since it is sometimes necessary to pick up larger boxes of fully packed goods during actual picking, and these boxes cannot be directly placed in the cargo frame 22, further improvements are made in this embodiment, specifically:

[0041] Combination Figure 1 As shown, the base frame 1 is provided with arm frames 4 on both sides of the picking shelf 2, wherein one end of the arm frames 4 is hinged to the base frame 1. It should be noted that the arm frames 4 are arranged on the upper wall of the base frame 1, and when the movable end of the arm frames 4 is flipped to the end away from the push handle 3, a bearing section 41 protruding from the picking shelf 2 for bearing cargo boxes is formed. When it is necessary to place cargo boxes, the bearing section 41 is flipped to the side away from the push handle 3, so that the lower wall of the arm frames 4 is naturally pressed on the upper wall of the base frame 1; in this way, the cargo boxes can be placed directly on the bearing sections 41, and when placing, the cargo boxes are placed on the two bearing sections 41 across the two bearing sections 41. When it is not necessary to place cargo, the arm frames 4 are flipped toward the end of the push handle 3, so that the arm frames 4 are naturally placed on the base frame 1, thereby reducing the space occupied by the arm frames 4.

[0042] In order to prevent the cargo box from sliding backwards, in this embodiment, Figure 1 As shown, the upper wall of the bearing section 41 is in the form of an inclined structure that is inclined downward toward the picking shelf 2; a support plate 5 is fixedly connected to the side wall of the picking shelf 2 close to the bearing section 41, wherein the side wall of the support plate 5 away from the shelf is in the form of an inclined structure, and the angle between the inclined surface of the support plate 5 and the inclined surface of the bearing section 41 is at a right angle, so that when a cargo box is placed on the inclined surface of the bearing section 41, the cargo box will naturally tilt toward the side of the support plate 5, thereby reducing the probability of the cargo box sliding backwards; and a slope perpendicular to the slope of the bearing section 41 is provided on the support plate 5, so that the side wall of the cargo box close to the support plate 5 can naturally fit on the inclined surface of the support plate 5, thereby ensuring the stable placement of the cargo box.

[0043] In order to increase the load-bearing capacity of the bearing section 41, in this embodiment, Figure 1 As shown, the end of the bearing section 41 away from the hinge end is bent downward to form a bent section 42, and the lower end of the bent section 42 is fixedly connected to a second roller 43. The second roller 43 can be a universal roller, and the bottoms of the first roller 11 and the second roller 43 are flush. Therefore, the bent section 42 and the second roller 43 can play an auxiliary supporting role for the end of the bearing section 41, thereby improving the load-bearing capacity of the bearing section 41.

[0044] In order to ensure the stability of the arm 4 when placing the cargo box for transportation, in this embodiment, Figure 2 As shown, a fixing assembly 6 for fixing the arm 4 is provided between the arm 4 and the base frame 1. When the arm 4 needs to be used to carry a cargo box, the fixing assembly 6 is first used to fix the arm 4 on the base frame 1 so that the arm 4 and the base frame 1 are fixed together.

[0045] Specifically, Figure 2 As shown, the arm 4 has a locking section 44 with an upper wall in a horizontal structure formed near one end of the hinged end; the horizontal locking section 44 mainly serves to facilitate the contact and locking of the gasket 63 and the screw at the back.

[0046] A waist-shaped hole 441 extending along the length direction of the arm 4 is opened on the locking section 44; the fixing assembly 6 includes a stud 61 whose lower end is vertically fixed on the base frame 1 and whose upper end is movable through the waist-shaped hole 441, and a locking nut 62 threadedly connected to the stud 61; a gasket 63 penetrating the stud 61 is placed between the locking nut 62 and the locking section 44.

[0047] When locking, first turn the arm 4 over to the use state, so that the stud 61 will pass through the waist-shaped hole 441 of the arm 4, and then put the gasket 63 and the locking nut 62 on the stud 61 until the gasket 63 is firmly pressed against the horizontal surface upper wall of the locking section 44; in this way, the fixation of the arm 4 is completed; similarly, when the arm 4 is no longer needed, remove the locking nut 62 and the gasket 63 in turn, and then rotate the arm 4 in the opposite direction to fold the arm 4 on the base frame 1, and then install the gasket 63 and the locking nut 62 on the stud 61 to prevent the gasket 63 and the locking nut 62 from being lost.

[0048] Implementation principle:

[0049] First, determine the state of arm 4 based on whether it is necessary to use arm 4:

[0050] When the arm 4 is needed to carry a cargo box, the arm 4 is flipped to the side away from the push handle 3 and fixed with the fixing assembly 6. At this time, the carrying section 41 of the arm 4 protrudes from the rear side of the picking shelf 2, so that the cargo box can be placed on the two carrying sections 41 for transportation. Figure 3 (shown)

[0051] When the arm 4 is not needed to carry the cargo box, the movable end of the arm 4 is flipped to the side close to the push handle 3 so that the entire arm 4 is folded on the base frame 1, thereby reducing the space occupied by the arm 4.

[0052] When receiving bulk goods or small cargo boxes, the bulk goods and small cargo boxes can be directly placed in the cargo frame 22.

[0053] When it is necessary to collect the bulk bottles, the height of the shelf 23 is first adjusted according to the height of the bottles, and then the bottles are passed through the through holes 231 of the shelf 23 with the bottom facing downward and dropped onto the bottom wall of the cargo frame 22 .

[0054] The above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the scope of protection required by the present invention.
