Description

Adjustable shelf trolley

The present invention relates to a stroller, and more particularly to a stroller that can be folded and has a function of adjusting height and angle.

Fruit and vegetable sales are usually placed on the shelves for consumers to choose; in order to make consumers easy to choose, the common fruit and vegetable shelves can be roughly divided into two types: one is the distance between the adjustable top seat and the ground, but the top The fixed angle of the shelf; the other is a shelf that can adjust the tilt angle of the top seat, but the distance between the top seat and the ground is fixed. However, shelves that can simultaneously adjust the tilt angle of the top seat and the distance from the ground are relatively rare, and most of them are bulky and inconvenient to move.

In view of this, the main object of the present invention is to provide an adjustable shelf cart having the function of folding and adjusting the relative height and angle of the top seat.

In order to achieve the above object, an adjustable shelf cart of the present invention includes a base including a first direction; a second direction perpendicular to the first direction; and a first end defined along the first direction a second end, located on the opposite side of the first end; a latching portion disposed on the top surface of the base and located at a second end of the base, the plurality of arrays being arranged along the first direction a snap groove on the top surface of the base; and a plurality of wheels arranged at intervals on the bottom surface of the base; a top seat disposed above the support frame; a support frame connecting the base and the top seat, the a first frame and a second frame pivotally connected to each other, wherein one end of the first frame is pivotally connected to the first end of the base, and one end of the second frame is selectively latched on the base a set of card slot, the top end of the top seat pivotally connected to the top end of the support frame; and a support rod, one end of which is pivotally connected to the bottom surface of the top seat, and the other end is provided with a snap member, the card The connector is detachably coupled to the support frame.

Using the above technical means, the power gains that can be obtained by the present invention are as follows:

1. The adjustable shelf cart of the present invention is provided with a multi-array card slot, and the distance between the top seat and the base can be changed by changing the snap groove of the support frame, and by the support rod and The connection of the support frame changes the inclination angle of the top seat while changing the height of the top seat.

2. The novel model can be folded into a minimum volume by the pivotal and overlapping design of the base, the top seat and the support frame, which is convenient for collection and movement, and easy to package and transport.

Referring to FIG. 1 to FIG. 3 , a preferred embodiment of the adjustable shelf cart of the present invention comprises a base 10 , a top seat 20 , a support frame 30 , and a support bar 40 .

The base 10 is a rectangular metal frame, and includes a first direction X, a second direction Y, a first end, a second end, a latching portion 11, and a plurality of wheels 13, wherein The first direction X is perpendicular to the second direction Y, and the first end and the second end are respectively defined as opposite ends of the base 10 along the first direction X; the latching portion 11 is disposed on the top surface of the base 10 And adjacent to the second end of the base 10, comprising two rows of latching slots 111 arranged in the first direction X spaced apart from the top surface of the base 10, and the two rows of corresponding snap slots 111 is a group; the plurality of wheels 13 are arranged at intervals on the bottom surface of the base 10 to drive the base 10 to slide on the ground.

The top seat 20 is a rectangular metal frame disposed above the base 10 for carrying the container. Preferably, the top end 20 is provided with a protection perpendicular to the frame of the top seat 20 and extending upward. The frame 21 is for supporting the container, and the frame 21 can be rotated and folded when not in use.

The first frame body 31 is pivotally connected to the first end of the base 10. The crossbar portion 313 is away from the first end of the base 10. The two cross-bar portions 333 and 335 of the second frame body 33 are respectively connected to opposite ends of the two side rod portions 331 . The cross-bar portion 335 of the second frame body 33 adjacent to the second end of the base frame 10 is a round rod. The second frame body 33 is pivotally connected to the top end 20 of the first end of the base 10 , and the top seat 20 is pivotally connected to the top end 20 of the base 10 . The protective frame 21 is disposed at a pivotal end of the second frame 33. Preferably, the base 10 is provided with a limiting frame 15 at the latching portion 11, and the second frame 33 is adjacent to the second end. The latching portions 335 and the latching slots 111 of the latching portion 11 of the base 10 are located in the limiting frame 15 for limiting the range in which the second frame 33 can be moved.

The support rod 40 is pivotally connected to the bottom surface of the top seat 20, and the other end is provided with a latching member 41. The latching member 41 is detachably connected to the crossbar portion 313 of the first frame body 31 of the support frame 30. on.

Referring to FIG. 4 to FIG. 6 , the first frame body 31 and the second frame body 33 of the support frame 30 are pivoted to be horizontally overlapped and stacked on the base 10 . The support rod 40 is not connected to the support frame 30 and is folded on the bottom surface of the top seat 20. The top seat 20 is stacked on the support frame 30, and the protective frame 21 is rotated inwardly to be folded on the top seat. 20, the shelf cart of the present invention is formed into a minimum volume; preferably, a connecting member 50 is disposed between the base 10 and the top seat 20, and the base 10 and the top seat are detachably connected in a folded state. 20, and the bottom surface of the top seat 20 is provided with a fastener 42 which can be locked in the fastener 42 when not in use.

Referring to FIG. 7 , in the second combination state of the present invention, the first frame body 31 and the second frame body 33 of the support frame 30 are horizontally overlapped, and the engaging member 41 of the support rod 40 is locked on the same. The first frame 31 is adjacent to the crossbar portion 313 of the second end to propp the top seat 20 at an oblique angle.

Please refer to FIG. 1 , FIG. 3 and FIG. 8 , which are the first and third combined states of the present invention. At this time, the crossbar portion 335 of the second frame 33 of the support frame 30 is embedded in one of the engaging slots. The first frame body 31 and the second frame body 33 of the support frame 30 are formed in a cross shape to stand on the base 10, and the top seat 20 is driven upwards away from the base 10. The pivot of the top seat 20 The distance from the terminal to the base 10 changes with the distance between the engaging slot 111 of the second frame 33 of the support frame 30 and the first end of the base 10, when the second frame 33 is embedded. The smaller the distance between the card slot 111 of the card and the first end of the base 10, the greater the distance between the pivotal end of the top seat 20 and the base 10, and the card can be inserted by changing the second frame 33.
