[0039] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0040] First embodiment

[0041] like Figure 1-10 As shown, a telescopic foldable trolley is used for storage and transportation in various occasions such as the catering industry, medical institutions, beauty and hairdressing industry, and home use. The telescopic foldable trolley includes a frame 10, a storage basket 20, and a sliding assembly, wherein the frame 10 has a first telescopic frame 100 and a second telescopic frame 101, and universal wheels 15 are provided at the lower ends of the first telescopic frame 100 and the second telescopic frame 101.

[0042] A plurality of storage baskets 20 are provided, and the plurality of storage baskets 20 are stacked and installed along the vertical direction of the first telescopic frame 100 and the second telescopic frame 101, and the storage basket 20 has a first basket body 200 and a second basket body 201, and the opposite ends 2011 of the first basket body 200 and the second basket body 201 are movably connected to each other in the horizontal direction, thereby forming a complete storage basket 20.

[0043] More specifically, the opposite ends of the first basket body 200 and the second basket body 201 are movably connected to each other through a sliding assembly, and slide towards each other or away from each other in the horizontal direction. When the first basket body 200 and the second basket body 201 slide in the horizontal direction, the first telescopic frame 100 and the second telescopic frame 101 also telescope along the sliding direction of the first basket body 200 and the second basket body 201.

[0044] When the sliding assembly adopts a sleeve basket frame 30, when the first basket body 200 and the second basket body 201 are installed, the sleeve basket frame 30 is sleeved on the opposite ends 2011 of the first basket body 200 and the second basket body 201. Specifically, the left and right ends of the sleeve basket frame 30 have sleeve holes 302, and the opposite ends 2011 of the first basket body 200 and the second basket body 201 are movably connected to the sleeve holes 302 at the left and right ends of the sleeve basket frame 30, and the first basket body 200 and the second basket body 201 slide in the sleeve holes 302 to approach each other or move away from each other; it can be seen that when the first basket body 200 and the second basket body 201 approach each other, the overall length of the storage basket 20 is reduced; when the first basket body 200 and the second basket body 201 move away from each other, the overall length of the storage basket 20 is increased, thereby adjusting the size and capacity of the storage basket 20.

[0045] The distal ends 2012 of the first basket body 200 and the second basket body 201 are both connected to the first telescopic frame 100 and the second telescopic frame 101 , so that the storage basket 20 is installed on the frame.

[0046] More specifically, the first telescopic frame 100 has a vertical rod 1001 and a vertical rod 2 1002, wherein the vertical rod 1001 is connected to the distal end 2012 of the first basket body 200, the vertical rod 2 1002 is connected to the distal end 2012 of the second basket body 201, and the vertical rod 1001 and the vertical rod 2 1002 are movably connected to each other through the first telescopic component 11, that is, the first telescopic component 11 has the function of telescopically adjusting its own length, one end of the first telescopic component 11 is connected to the vertical rod 1 1001, and the other end of the first telescopic component 11 is connected to the vertical rod 2 1002.

[0047] Therefore, the first vertical rod 1001 and the second vertical rod 1002 can move toward each other or move away from each other along the sliding direction of the first basket body 200 and the second basket body 201, thereby realizing the telescopic action of the first telescopic frame 100, that is, adjusting the overall length of the first telescopic frame 100.

[0048] The second telescopic frame 101 has a vertical rod three 1011 and a vertical rod four 1012, wherein the vertical rod three 1011 is connected to the distal end 2012 of the first basket body 200, and the vertical rod four 1012 is connected to the distal end 2012 of the second basket body 201. The upper end of the vertical rod three 1011 and the upper end of the vertical rod four 1012 are movably connected to each other through a sleeve 14. The sleeve 14 is an internal hollow structure, so the upper end of the vertical rod three 1011 and the upper end of the vertical rod four 1012 can be inserted into the hole of the sleeve 14 and slide toward each other or in the opposite direction in the hole of the sleeve 14.

[0049] The lower end of the vertical rod 3 1011 and the lower end of the vertical rod 4 1012 are movably connected to each other through the second telescopic assembly 12, that is, the second telescopic assembly 12 has the function of telescopically adjusting its own length, one end of the second telescopic assembly 12 is connected to the vertical rod 3 1011, and the other end of the second telescopic assembly 12 is connected to the vertical rod 4 1012. Therefore, the vertical rod 3 1011 and the vertical rod 4 1012 can also move towards each other or move away from each other in the sliding direction of the first basket body 200 and the second basket body 201, thereby realizing the telescopic action of the second telescopic frame 101, that is, adjusting the overall length of the second telescopic frame 101.

[0050] In this way, the storage basket 20 provided by the present application has the opposite ends 2011 of the first basket body 200 and the second basket body 201 movably connected by a sliding assembly, so that the first basket body 200 and the second basket body 201 can move towards each other or move away from each other, thereby adjusting the body length and storage space of the storage basket 20; because the distant ends 2012 of the first basket body 200 and the second basket body 201 are both connected to the first telescopic frame 100 and the second telescopic frame 101, the first telescopic frame 100 and the second telescopic frame 101 can be telescoped along the sliding direction of the first basket body 200 and the second basket body 201, thereby realizing the length adjustment of the overall structure of the trolley.

[0051] When the sliding assembly adopts a socket basket frame, the opposite ends 2011 of the first basket body 200 and the second basket body 201 are movably connected to the socket hole 302 of the socket basket frame 30, so that the first basket body 200 and the second basket body 201 can slide towards each other or away from each other in the socket hole 302, thereby realizing the length adjustment of the storage basket 20; compared with the implementation means of the storage basket 20 and the frame of the previous carts adopting the overall fixed structure, the present application sets the storage basket 20 and the frame to be able to adjust their own lengths, so as to adjust the length and capacity of the storage basket 20 according to the space of the use scene, and adjust the length of the frame, so that the use scene of the trolley is wider; and the storage is more convenient, without the need to completely disassemble the storage basket 20, the frame, the rollers and other components as in the past, reducing the complexity of disassembly and assembly, saving time and labor, and improving the user experience.

[0052] The sleeve basket 30 comprises a first basket 300 and a second basket 301 . The first basket 300 and the second basket 301 are substantially in a U-shaped groove structure. Therefore, both edges of the first basket 300 and the second basket 301 are provided with vertical enclosing edges.

[0053] When installing the sleeve basket 30, the second basket 301 is installed on the inner side of the first basket 300, so that the vertical enclosed edge of the first basket 300 is fixedly connected with the vertical enclosed edge of the second basket 301, and a gap is set between the opposite surfaces of the first basket 300 and the second basket 301 to form the sleeve hole 302. Therefore, the opposite ends 2011 of the first basket body 200 and the second basket body 201 are inserted into the sleeve hole 302, and then inserted between the first basket 300 and the second basket 301, and the vertical enclosed edges of the first basket 300 and the second basket 301 will cover the vertical enclosed edges of the first basket body 200 and the second basket body 201.

[0054] In addition, a limiting hole 303 is provided on the vertical enclosure edge of the first basket frame 300 or the second basket frame 301, and the limiting hole 303 is extended along the direction of the first basket body 200 and the second basket body 201 approaching each other or moving away from each other. A limiting member 202 is provided on the vertical enclosure edge of the first basket body 200 and the second basket body 201. When the opposite ends 2011 of the first basket body 200 and the second basket body 201 are inserted into the sleeve hole 302, the limiting member 202 can be embedded in the limiting hole 303. When the first basket body 200 and the second basket body 201 are slid, the limiting member 202 can naturally slide along the opening direction of the limiting hole 303. Therefore, the limiting member 202 slides within the hole length range of the limiting hole 303, thereby limiting the sliding distance of the first basket body 200 and the second basket body 201 in the sleeve hole 302.

[0055] In this way, by inserting the opposite ends 2011 of the first basket body 200 and the second basket body 201 into the socket hole 302, and when the opposite ends 2011 of the first basket body 200 and the second basket body 201 slide in the socket hole 302, the limiting piece 202 on the vertical enclosing edge can be limitedly matched with the limiting hole 303, so that the sliding range of the limiting piece 202 in the limiting hole 303 is limited, and the sliding distance of the opposite ends 2011 of the first basket body 200 and the second basket body 201 in the socket hole 302 is limited, thereby limiting the length adjustment range of the storage basket 20.

[0056] The first telescopic assembly 11 and the second telescopic assembly 12 both have a connecting rod 110 and a connecting tube 111, wherein the connecting rod 110 of the first telescopic assembly 11 is connected to the vertical rod one 1001, and the connecting tube 111 of the first telescopic assembly 11 is connected to the vertical rod two 1002; the connecting rod 110 of the second telescopic assembly 12 is connected to the vertical rod three 1011, and the connecting tube 111 of the second telescopic assembly 12 is connected to the vertical rod four 1012.

[0057] More specifically, one end of the connecting rod 110 has an anti-slip head 1101, and the outer diameter of the anti-slip head 1101 is smaller than the inner diameter of the connecting tube 111. Therefore, one end of the connecting tube 111 can be sleeved on the end of the connecting rod 110 provided with the anti-slip head 1101, and the end of the connecting rod 110 provided with the anti-slip head 1101 can slide in the connecting tube 111. The connecting tube 111 is provided with an anti-slip portion 1110 that is concave toward the tube hole, and the anti-slip portion 1110 is arranged around the circumference of the connecting tube 111, and the anti-slip portion 1110 can prevent the anti-slip head 1101 of the connecting rod 110 from sliding out of the tube hole of the connecting tube 111, thereby preventing the connecting rod 110 from being separated from the connecting tube 111.

[0058] In addition, a locking sleeve 13 is sleeved on the connecting rod 110, one end of the locking sleeve 13 is a sleeve hole 130, and the other end is a tensioning head 132 with a notch 131. The tensioning head 132 has a certain elastic tightening effect by providing the notch 131, and the outer wall of the tensioning head 132 of the locking sleeve 13 is provided with a block 133 protruding outward. A clamping hole 1111 is provided on the tube wall of the connecting tube 111 and penetrates the inside and outside of the connecting tube 111. When the connecting rod 110 is inserted into the connecting tube 111, the elastic head 132 of the locking sleeve 13 is also inserted into the tube mouth of the connecting tube 111, and the inner wall of the connecting tube 111 is tightened by the elastic tightening effect of the elastic head 132, and the clamping block 133 is clamped in the clamping hole 1111, so that the connecting rod 110 is locked on the connecting tube 111 through the locking sleeve 13, and the connection length of the connecting rod 110 and the connecting tube 111 is locked, thereby locking the distance between the vertical rod 1 1001 and the vertical rod 2 1002 of the first telescopic frame 100, and locking the distance between the vertical rod 3 1011 and the vertical rod 4 1012 of the second telescopic frame 101, thereby improving the structural stability of the frame when it is in the unfolded state.

[0059] The first telescopic frame 100 and the second telescopic frame 101 are movably connected to each other through a folding link 40. The folding link 40 includes a link 1 400 and a link 2 401. A slot is provided at one end of the link 1 400, and a buckle is provided at one end of the link 2 401. Therefore, when the link 1 400 and the link 2 401 are unfolded and connected, the buckle of the link 2 401 and the slot of the link 2 401 can be buckled and connected, locking the unfolded connection state of the link 1 400 and the link 2 401. In addition, the other end of the link 1 400 is movably connected to the first telescopic frame 100, and the other end of the link 2 401 is movably connected to the second telescopic frame 101. Through the buckle connection between the link 1 400 and the link 2 401, the structural stability of the unfolded state between the first telescopic frame 100 and the second telescopic frame 101 is locked. When the first telescopic frame 100, the second telescopic frame 101 and the storage basket 20 are stored, the buckle of the first connecting rod can be separated from the slot of the second connecting rod, which is simple and convenient to operate.

[0060] The second embodiment, the third embodiment and the fourth embodiment are provided below. The difference between the second embodiment and the first embodiment is the selection of the sliding assembly. The rest of the embodiments are the same and will not be described again.

For example, a slider is provided on the opposite end of the first basket body 200, and a slot is provided on the opposite end of the second basket body 201. The first basket body 200 is assembled with its slider on the slot, so that the first basket body 200 and the second basket body 201 can slide toward each other or away from each other through the sliding assembly connection of the slider and the slot.

[0063] Third embodiment

[0064] The sliding assembly may adopt a pulley and slide rail assembly. For example, pulleys are arranged on opposite ends of the first basket body 200, and slide rails are arranged on opposite ends of the second basket body 201. The first basket body 200 is assembled on the slide rail, so that the first basket body 200 and the second basket body 201 can slide toward each other or away from each other through the sliding assembly connection of the pulley and slide rail.
