The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

In this application, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number, order of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "plurality" is at least two, such as two, three, etc., unless explicitly defined otherwise.

Referring to fig. 1 to 4, the present application provides a carrying device 1000, which includes a frame 100, a mounting base 200, a swinging member 300 and a pull handle 400, wherein the frame 100 has a receiving space, the receiving space can be used for loading goods or carrying children, and wheels for moving can be mounted at the bottom. In fig. 1, the frame 100 is referenced to have a corresponding length X, width Y, and height Z.

The mount 200 is disposed on one side of the frame 100, the swing member 300 is capable of tilting relative to the mount 200 about an axis 310 (shown in phantom) inclined at a certain angle relative to the plumb direction, the pull handle 400 is mainly used for applying a pulling force or a pushing force (hereinafter referred to as a force) to drive the movement of the frame 100, the pull handle 400 is connected to the swing member 300, and in a natural state (when no artificial force is applied), the center of gravity 410 is located below the axis 310. In fig. 4, the right side of the axis 310 is above, the left side is below, and the carrier is placed on a horizontal plane, where the plumb direction is the height direction.

In connection with fig. 3 to 6, it is shown from different views, respectively, that when the pull handle 400 deflects to one side in the width direction (the other side is the same), the swing member 300 is displaced in the height direction, and the center of gravity 410 of the pull handle is then moved up to the position shown in fig. 4 and 6. Once the force is released, the pull handle 400 is rotated by gravity until the center of gravity 410 is at its lowest point (see FIGS. 3 and 5), which corresponds to the pull handle 400 being in a centered position, i.e., the pull handle is centered. Wherein the mounting seat 200 is preferably provided at one side of the frame 100 in the length direction, and the movement of the carrier is easier. The centered position is where the pull handle 400 is the same distance from both sides of the frame width direction.

Wherein the center of gravity of the oscillating member 300 is also below the axis 310. For ease of illustration and understanding, the center of gravity of both are shown as being combined into one center of gravity 410.

In one embodiment, as shown in fig. 5, the end of the pull handle 400 is provided with a base 500 rotatably connected to the swinging member 300, and the base 500 can rotate around a horizontal axis 320 relative to the swinging member 300, and the pull handle can be used by an operator in various postures, so as to facilitate the pulling operation.

Wherein as shown in fig. 7 and 8, an elastic member 610 for driving the pull handle 400 to be switched to the vertical state in the natural state is provided between the pull handle 400 and the swing member 300. Specifically, the elastic member 610 is a pair of torsion springs, and is disposed at two sides of the base 500, so as to improve the speed and stability of the pull handle reset. To avoid the reset transition of the pull handle 400, the swing member 300 is provided with a blocking portion 330 which keeps it in a vertical state against the pull handle 400.

As shown in fig. 7 to 10, in an embodiment, the swing member 300 has a first notch 341 and a second notch 342 which accommodate the base 500 and the mount 200, facilitating assembly, and making the structure between the components more compact. Wherein the swinging member 300 includes a housing 350 and an inner metal skeleton 360. The housing 350 serves to cover the metal skeleton 360, making the appearance more compact. The metal frame 360 serves as a support member, and includes a first metal frame 361 rotatably coupled to the mount 200 and a second metal frame 362 coupled to the pull handle 400, and is fixed therebetween by a fastener or welding, etc. The housing 350 may be a plastic member including a first housing 351 and second housings 352 disposed at both sides of the first housing 351, the second housing 352 being rotatably connected with the base 500, and one end of the elastic member acting on the second housing 352. Wherein the inner cavity of the second housing 352 is provided with a convex column 353 for the torsion spring to be sleeved.

In one embodiment, the frame 100 has a horizontally disposed rail 110, and the mount 200 is secured to the rail 110. The cross bar 110 is located at the bottom of the frame 100, and the mounting base 200 and the cross bar 110 are fixed along the axial direction of the axis 310, that is, the mounting base 200 is fixed on the cross bar 110 in an inclined posture, so that the subsequent swinging member 300 is convenient to install. Wherein the carrier further comprises a pivot 700 connecting the swinging member 300 through the crossbar 110 and the mount 200.

In one embodiment, mount 200 is provided with a bearing 710 that fits over pivot 700 (the pivot axis being coaxial with axis 310). The bearing 710 serves to improve the smoothness of rotation between the swing member 300 and the mount 200. Specifically, the bearings 710 are nested on two sides of the mounting base 200 along the axis 310, the swinging member 300 has connection portions 370 matching with two sides of the mounting base 200 along the axis 310, and the second metal frame 362 is bent by metal plates to form two connection portions 370.

Further preferably, the inner wall of the connecting portion 370 is provided with an annular step 371 in a protruding manner, and in an assembled state, the annular step 371 abuts against one end surface of the bearing 710, and the connecting portion 370 is arranged at a distance from the mounting seat 200, so that a contact surface is reduced, and friction resistance is reduced.

The automatic aligning action of the pull handle of the carrying device is as follows:

the acting force is released, the pull handle returns to the vertical state under the driving of the elastic piece, and simultaneously, the pull handle rotates until the pull handle returns to the middle position under the action of gravity, namely, the pull handle returns to the normal state.

The carrying device realizes automatic centering of the pull handle through gravity, omits the existing short rod structure, simplifies the structure, and is convenient to assemble and reduces the manufacturing cost.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description. When technical features of different embodiments are embodied in the same drawing, the drawing can be regarded as a combination of the embodiments concerned also being disclosed at the same time.

The foregoing examples represent only a few embodiments of the present application, which are described in more detail and are not thereby to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
