[0027] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings, and those skilled in the art will appreciate that the descriptions are merely descriptive, exemplary and should not be interpreted as limiting the scope of protection of the present application.

[0028] It should be noted that similar reference numerals represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it can not be further defined and explained in subsequent drawings.

[0029] The present embodiment mainly describes the folding structure of the handcart handle which can effectively avoid the influence of the receiving groove structure on the transport plate on the placement of the carried objects, and the specific implementation is as follows:

[0030] As shown in Figures 1-5 , the folding structure of the handcart handle includes a transport plate 1 provided with a lower opening groove, a connecting rod 2 provided in the groove and fixedly installed by screws, a handle 3 rotatably sleeved on the connecting rod 2 through a sleeve 3a, a rotation-limiting member 4 slidably sleeved on the connecting rod 2 and limiting the rotation of the sleeve 3a through the concave-convex structure cooperation, a limiting pin 5 fixed on the connecting rod 2 and capable of limiting the rotation and sliding stroke of the rotation-limiting member 4, and an acting member 6 elastically supporting and limiting the handle 3.

[0031] The conveying plate 1 is provided with a through movable opening 11, and the rotation limiting member 4 is provided with an action part 41. The action part 41 is exposed above the conveying plate 1 from the movable opening 11. By pushing the action part 41, the rotation limiting member 4 slides on the connecting rod 2. The rotation limiting member 4 disengages from the concave-convex fit between the handle 3 and the sleeve 3a, so that the handle 3 can rotate relative to the conveying plate 1 on the connecting rod 2.

[0032] In this embodiment, the transport plate 1 is provided with a clearance opening 12, which extends vertically and connects to the side wall of the transport plate 1. The handle 3 also includes a telescopic rod 3b that is fixedly connected to the sleeve 3a. The telescopic rod 3b of the handle 3 can be rotated to the top of the transport plate 1 for pushing and pulling or rotated to the bottom of the transport plate 1 for storage through the clearance opening 12.

[0033] In this application, the handle 3 can be rotated to the bottom of the transport plate 1, and the rotation limiter 4 limits the handle 3, so that the upper surface of the transport plate 1 does not need to be provided with a storage groove for the handle 3. When the transported object is placed on the transport plate 1, it can effectively avoid the situation of the transported object being placed unevenly, so that the transported object is stacked normally on the transport plate 1 and the trolley can be pulled normally.

[0034] like Figures 3-4 As shown, the handle 3 is provided with two sleeves 3a that are rotatably sleeved on the connecting rod 2, and the sleeves 3a are provided with a number of recessed slots 3a1. The slots 3a1 are distributed around the rotation axis, and the rotation limiting member 4 is provided with a plug 43 that can be inserted into the slots 3a1. By the plug 43 cooperating with the slots 3a1 at different positions, the rotation angle of the handle 3 on the connecting rod 2 can be limited, that is, the tilt of the handle 3 relative to the moving plate 1 can be limited.

[0035] To prevent the rotation limiter 4 from rotating on the connecting rod 2, in this embodiment, the rotation limiter 4 is provided with a sliding groove 42, and a limiting pin 5 inserted into the sliding groove 42 is fixed on the connecting rod 2. When the rotation limiter 4 slides along the connecting rod 2, the limiting pin 5 restricts the rotation limiter 4 from rotating on the connecting rod and limits the sliding stroke of the rotation limiter 4 on the connecting rod 2.

[0036] In other embodiments, the rotation limiting member 4 and the connecting rod 2 are fitted with a non-circular structure, such as an ellipse or a polygon, to limit the rotation of the rotation limiting member 4 on the connecting rod 2.

[0037] like Figure 4 As shown, there are two limiting members 4 that are sleeved on the connecting rod 2 and are located between the two sleeves 3a of the handle 3. The actuating member 6 is a spring that is sleeved on the connecting rod 2 and is located between the two limiting members 4. Preferably, the actuating member 6 can also be a tension spring, rubber band or other accessories.

[0038] In order to avoid the two sets of pipes 3a of the handle 3 from sliding when the limiting rotation piece 4 slides on the connecting rod 2, two blocking walls 14 are arranged below the board 1, and the two rotating sleeves on the handle 3 are located between the two blocking walls 14, and in order to avoid the pipe 3a of the handle 3 from rubbing against the blocking wall 14 when the pipe 3a rotates, the connecting rod 2 is further sleeved with a partition 7, and the partition 7 is located between the pipe 3a and the blocking wall 14.

[0039] In other embodiments, the limiting rotation piece 4 can be located between the blocking wall 14 and the pipe 3a or between the partition 7 and the pipe 3a, and the acting piece 6 is located between the blocking wall 14 and the limiting rotation piece 4 or between the partition 7 and the limiting rotation piece 4.

[0040] As shown in Figs. Figure 3 and As shown in Figs. Figure 5 The upper end surface of the board 1 is provided with a plurality of counterbores 13, and the nuts of the screws fixedly connected with the connecting rod 2 are located in the counterbores 13, and the screws are threadedly connected with the connecting rod 2; or the screws are fixedly connected with the board 1 and the connecting rod 2 in cooperation with the nuts, and the nuts or the screw caps of the screws are located in the counterbores 13, and the screw caps and the nuts sandwich the board 1 and the connecting rod 2 to be fixed.

[0041] In order to facilitate the sleeving installation of the limiting rotation piece 4, the handle 3 and the acting piece 6 on the connecting rod 2, the connecting rod 2 can adopt an L-shaped or a linear structure.

[0042] Since the height of the board 1 of the trolley is low, in order to avoid the mud on the ground from splashing between the limiting rotation piece 4 and the pipe 3a when the trolley is pulled and transported by rolling wheels, a baffle 8 is arranged below the connecting rod 2, and the baffle is fixedly connected with the board 1 by screws and nuts.

[0043] In the description of the present application, it should be pointed out that the terms "upper", "lower", "front", "rear", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the product of the present application is used, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0044] The folding structure of the trolley handle provided by the present application has been described in detail above, and in this paper, specific examples are applied to describe the principles and implementation modes of the present application, and the above description of the embodiments is only used to help understand the present application and the core idea, and it should be pointed out that for ordinary skilled persons in the technical field, without departing from the principles of the present application, the present application can be improved and modified in many ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
