[0046] See also Figures 1 to 9 The present application provides a trolley with a handle (hereinafter referred to as trolley 1000), which includes a frame structure 100 with wheels, and a handle 300 is movable relative to the frame structure 100, including but not limited to the handle 300 being rotatably connected to the frame structure 100 as shown in the figure.

[0047] The handle 300 includes an upper handle bar 310, a lower handle bar 320 and a locking member 330, wherein the lower handle bar 320 is connected to the frame structure 100, and the upper handle bar 310 and the lower handle bar 320 are slidably matched. The locking member 330 is rotatably arranged on the lower handle bar 320 via a rotating shaft 331, and has a locking portion 332 that acts on the upper handle bar 310 to limit the sliding of the upper handle bar 310, and an operating portion 333 that releases the locking portion 332 from acting on the upper handle bar 310. The locking portion 332 and the operating portion 333 are arranged on both sides of the rotating shaft 331, that is, the movement directions of the two are opposite to each other based on the upper handle bar 310. Specifically:

[0048] During the unlocking process, the operating part 333 is driven to approach the upper handlebar 310 , and the locking part 332 moves away from and releases the effect on the upper handlebar 310 ; during the locking process, the operating part 333 is driven to move away from the upper handlebar 310 , and the locking part 332 moves closer until it acts on the upper handlebar 310 .

[0049] In the trolley of the present application, the locking member is connected by rotation, and the operating part and the locking part are arranged on both sides of the rotating shaft to realize the unlocking operation after pressing, eliminating the pull wire and the locking member serving as the unlocking member, and the structure is simpler.

[0050] The upper handlebar 310 has one or more different height positions relative to the lower handlebar 320 .

[0051] The driving force of the operating part 333 is applied manually when unlocking, and can be applied manually or the trolley 1000 includes an elastic member 340 acting on the locking member 330 to reset it when locking. The elastic member 340 includes but is not limited to the spring shown in the figure.

[0052] In one embodiment, the handle 300 includes a base 350 fixedly disposed on the lower handlebar rod 320, and the locking member 330 is rotatably disposed on the base 350. The elastic member 340 is installed in the base 350, and its two ends act on the base 350 and the operating portion 333 respectively. The end of the operating portion 333 is recessed to provide an operating area 334 for fingers to fit each other. The operating area 334 is L1 away from the rotating shaft 331, and the elastic member 340 acts on the operating portion 333 at a distance of L2 from the rotating shaft 331, and L2 / L1=0.4-0.6, preferably 0.5.

[0053] The upper handle bar 310 slides inside the lower handle bar 320, and the base 350 is fixedly arranged on the top of the lower handle bar 320. The lower handle bar 320 is a straight bar, and the base 350 extends along the extension direction of the lower handle bar 320. The length of the base 350 is about the width of an adult's palm, which is convenient for gripping and unlocking operations. The specific length meets 70-90 mm, preferably 75 mm.

[0054] Regarding the specific structure of the locking member 330, the locking portion 332 includes a limit block 3321 matched with the lower handlebar 320, and a locking tongue 3322 protruding relative to the limit block 3321, and the upper handlebar 310 is provided with a locking groove 311 matched with the locking tongue 3322. The lower handlebar 320 is provided with a limit groove 321 matched with the limit block 3321, wherein the bottom of the base 350 is open and plugged into the outer periphery of the lower handlebar 320, and after the locking member 330 is installed on the base 350 through the rotating shaft 331, the limit block 3321 is always in the limit groove 321 to play a role in relatively fixing the base 350 and the lower handlebar 320.

[0055] The limit block 3321 has a limit portion 3323. When the locking member 330 is in the locked state, the limit portion 3323 abuts against the outer wall of the upper handlebar 310. In the figure, the limit portion 3323 is the end face of the limit block 3321. Correspondingly, the handle 300 also includes a guide member 360 that acts on the outer wall of the upper handlebar to make it coaxially arranged relative to the lower handlebar 320. The guide member 360 is fixedly arranged on the lower handlebar 320 and arranged opposite to the locking member 330. The "opposite arrangement" is arranged on both sides of the radial direction and at the same horizontal position as shown in the figure. The top of the base 350 is also provided with a sliding hole 351 which is in clearance with the upper handle bar 310, so as to coaxially position the upper handle bar 310. For example, in the locked state, the guide member 360 and the limiter 3323 act on the upper handle bar 310 to reduce the shaking of the upper handle bar 310; in the unlocked state, the guide member 360 and the lock tongue 3322 act on the upper handle bar 310, so that the upper handle bar 310 slides coaxially relative to the lower handle bar 320. In the figure, the guide member 360 has an elastic block 361 acting on the outer wall of the upper handle bar.

[0056] In one embodiment, a limiting mechanism is provided between the upper handle bar 310 and the guide member 360 to limit the upper handle bar 310 from being separated from the lower handle bar 320, and the limiting mechanism includes:

[0057] A stopper 312 is provided at the bottom of the upper handlebar 310;

[0058] The blocking portion 362 is disposed on the guide member 360 and cooperates with the limiting member 312 .

[0059] Among them, the upper handlebar rod 310 has multiple gears with different heights relative to the lower handlebar rod 320. Combined with the aforementioned upper handlebar rod 310 with a locking groove 311, that is, there are multiple locking grooves 311 arranged at intervals along the sliding direction, two of which correspond to the lowest length of the handle 300, and the other corresponds to the longest length of the handle 300. When the handle 300 is at the longest length, the blocking part 362 and the limiting member 312 counteract each other.

[0060] In one embodiment, the frame structure 100 has a receiving space 110 with an open top, and a liner 200 disposed in the receiving space 110, and includes a bottom support frame 120, two oppositely arranged first side frames 130, and two oppositely arranged second side frames 140. The first side frames 130 and the second side frames 140 are adjacent and perpendicular to each other so that the side frames form a rectangular structure, wherein the two first side frames 130 are arranged at intervals along the length direction or the width direction, and the bottom support frame 120 and all the side frames enclose the receiving space 110.

[0061] In one embodiment, the upper handlebar 310 is a T-shaped structure, including a vertical bar and a horizontal bar connected to the top of the vertical bar.

[0062] The trolley of the present application has a locking member connected by rotation, and the operating part and the locking part are arranged on both sides of the rotating shaft to realize the unlocking operation after pressing, eliminating the pull wire and the locking member serving as the unlocking member, and the structure is simpler.

[0063] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0064] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
