In addition, besides the above-mentioned scheme that the pull rod 3 adopts a split structure, the pull rod of this scheme may also be of an integral single rod structure, and in the single rod structure, one end of the pull rod 3 is connected with the connection seat 162 through the rotating member 31, and the other end of the pull rod may be turned upwards or downwards around the end portion of the pull rod rotationally connected with the connection seat.

As shown in fig. 13, when the transferring device of the present embodiment is used, the pull rod 3 may be turned out, then the second pull rod 34 is pulled to make it face and be located at the position and direction where the user pulls the subsequent hand, and then the bracket rod 14 is pulled to expand the frame, during the expansion process, most of the first pull rod 161, the second pull rod 163 and the third pull rod 164 are connected by rotation, so when the bracket rod 14 is pulled, it may be easily expanded, after the expansion is completed, the connecting hook 411 and the corresponding connecting post 152 are detachably connected by rotating the restraining rod 151 of the restraining component 15, in this way, the expanded state of the frame 1 is locked, and the restraining rod 151 may be made of a metal sheet or a plastic sheet, by utilizing the characteristics that it has a deformability within a certain thickness, so that the connecting hook 1511 and the connecting post 152 are more tightly engaged when the hook is engaged, and when the hook is disengaged, the hook is conveniently detached (or unlocked) by applying a certain force; in this embodiment, after the frame 1 is unfolded, a supporting area for placing objects can be formed above the support rod 14, so that a user can install the support frame on the frame 1, then install the storage assembly, and finally can directly place the packaged objects to be transported above the frame 1.

Referring to fig. 13 to 15, when not in use, the support frame and the storage assembly can be removed, the expansion lock of the frame 1 can be released by releasing the constraint connection between the constraint rod 151 of the constraint assembly 15 and the connection post 152, and then the frame is folded from the support rods 14 on two sides of the frame 1 in the width direction of the frame 1, finally after being folded, the pull rod 3 is turned over (refer to fig. 15), and finally the transfer device is folded.

Example 5

As shown in connection with one of fig. 17 to 20, this embodiment is substantially the same as embodiment 4, and aims to provide an alternative solution to the vehicle frame 1, which is different from embodiment 4 in that in this embodiment, the connection assembly 16 of the vehicle frame 1 is different from embodiment 4, in this embodiment, a pair of the support rods 14 of the vehicle frame 1 are disposed in horizontal and relatively parallel, and the connection assembly 16 includes:

The first traction rods 161 are a pair and are in one-to-one correspondence with the pair of bracket rods 14, and one end of each first traction rod 161 is rotatably connected with one end of each bracket rod 14;

The connecting seat 162 is arranged between the pair of first traction rods 161, and the other ends of the pair of first traction rods 161 are respectively and rotatably connected with the two opposite sides of the connecting seat 162;

The third connecting rods 165 are a pair, the middle parts of the third connecting rods are in scissor-fork type rotary connection (through a rotary connecting shaft 1651), the pair of third connecting rods 165 are arranged between the pair of bracket rods 14, and one ends of the pair of third connecting rods 165 are respectively in rotary connection with the other ends of the pair of bracket rods 14;

A plurality of sliding guides 166, the sliding guides 166 being in one-to-one correspondence with the pair of the support bars 14, and the sliding guides 166 being fixed between both ends of the support bars 14; the other ends of the third connecting rods 165 are respectively connected with the sliding guides 166 in a relatively sliding manner through sliding connectors 1652, so as to realize the relative movement of the frame 1 when folding or unfolding, and the sliding guides 166 are specifically provided with sliding grooves 1661, and the sliding connectors 1251 are slidably connected with the sliding grooves 1661.

In this embodiment, when the restraint assembly 14 and the connection assembly 16 are in an unlocked state and the pair of support rods 14 of the frame 1 move in directions approaching or moving away from each other, the other ends of the pair of third connection rods 165 move relative to the support rods 14, so that the frame can be folded or unfolded in the width direction.

In the implementation structure of the restraint assembly 15, the restraint assembly 15 in this embodiment is a spacing member 153 with a rod-shaped structure, and the number of the spacing members 153 corresponds to that of the pair of bracket rods 14 one by one; the limiting member 153 is fixed at one end of the support rod 14, the limiting member 153 is used for limiting the rotation amplitude of the other end of the first traction rod 161 along the direction away from the other end of the support rod 14 to a preset value (in this embodiment, the limiting value is that the pair of first traction rods 161 are turned to be perpendicular to the support rod 14 or form an included angle range of 90 degrees + -15 degrees), when the other end of the first traction rod 161 rotates along the direction away from the other end of the support rod, the width of the frame 11, which is unfolded in the width direction, is locked in one direction when the first traction rod is abutted against the limiting member 153, at this time, the first traction rod 161 is stressed and cannot rotate along the direction close to the other end of the support rod 14 due to the fact that a user applies traction force through the pull rod 3, so that the frame 11 can be kept in an unfolded state.

In order to avoid interference between the stopper 153 and the first traction rod 161 when the frame 1 is folded, the first traction rod 161 and the stopper 153 have one of the following structures or positional relationships:

(1) As shown in fig. 20 (a), a portion of the first traction rod 161 near the limiting member 153 is provided with a avoiding structure 1611, and the avoiding structure 1611 is used to prevent one end of the first traction rod 161 from interfering with the limiting member 153 when the other end of the first traction rod 161 rotates in a direction approaching the other end of the supporting rod 1;

(2) As shown in fig. 20 (b), a preset interval is formed between the first traction rod 161 and one end of the limiting member 153, so that when the other end of the first traction rod 161 rotates in a direction approaching to the other end of the bracket rod 14, the virtual movement track of the first traction rod 161 does not cover the arrangement position of the limiting member 153, and when the other end of the first traction rod 161 rotates in a direction away from the other end of the bracket rod 14, the arrangement position of the limiting member 153 is located on the virtual movement track of the first traction rod 161, so that the pull rod 3 pulls the first traction rod 161 to a preset extent and then is locked (or limited) in one direction to continue moving.

One end of the pull rod 3 in the embodiment is connected with the connecting seat 162 through a rotating member (such as a rotating connecting pin, a connecting shaft, etc.), and the other end of the pull rod 3 can be turned upwards or downwards around the end of the pull rod 3 rotationally connected with the connecting seat 162; the structure of the pull rod 3 may be an integrated single rod structure or a split double rod structure as in embodiment 4, and will not be described here.

As shown in fig. 17 to 19, when the frame 1 of the transfer device according to the present embodiment is not in use, the pair of first traction rods 161 can be rotated in a direction approaching the other end of the bracket rod 14 by pushing the tension rod 3 in the opposite direction, so that the stopper 153 of the restraint assembly 4 is separated from contact with the first traction rods 161, and the user does not apply a pulling force to the tension rod 3 any more because the transfer device is not in use, so that the first traction rods 161 are abutted against the stopper 153, and instead, the first traction rods 161 are rotated in a direction approaching the other end of the bracket rod 14 by pushing the tension rod 3 in the opposite direction, so that the unfolded and locked state of the frame 1 is automatically released (refer to fig. 18); when the pair of support rods 14 and the connecting assembly are folded and furled, the pull rod 3 is finally furled and turned (refer to fig. 19 in particular), and the transfer device is folded.
