DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a logistics box that is convenient for transportation, including a base 1, a box body 11 is fixedly connected to the surface of the base 1, and two sets of side walls of the box body 11 are provided with multiple sets of positioning holes 12 distributed in an array. The outside of the box body 11 is sleeved with a top cover 2, and the top cover 2 can adjust the height along the outer wall of the box body 11. The positioning holes 12 cooperate with the limit assembly 5 to fix the height of the top cover 2.

[0032] Reference Figure 3The bottom surface of the base 1 is provided with a storage groove 3, which is used to install and store the walking assembly 4. The walking assembly 4 is arranged inside the storage groove 3, and the walking assembly 4 is used to facilitate the movement of the logistics box as a whole. The walking assembly 4 includes a slide plate 41, which is slidably connected inside the storage groove 3. The slide plates 41 are symmetrically arranged in two groups, and a bidirectional threaded rod 42 is threadedly connected between the two groups of slide plates 41. The bidirectional threaded rod 42 penetrates and is rotatably connected to the side wall of the base 1. The bidirectional threaded rod 42 is used to drive the two groups of slide plates 41 to move toward or away from each other, thereby adjusting the position between the two groups of slide plates 41. The end of the bidirectional threaded rod 42 is fixedly connected with a brake wheel 43, and the brake wheel 43 located on the bidirectional threaded rod 42 facilitates manual rotation of the bidirectional threaded rod 42.

[0033] Reference Figure 3 The bottom surfaces of the slide plate 41 and the base 1 are both provided with mounting grooves 44, and the mounting grooves 44 are hinged with support plates 45. The two groups of mounting grooves 44 respectively fix the ends of the two groups of support plates 45, and make the support plates 45 rotate in the mounting grooves 44. The adjacent ends of the two groups of support plates 45 are hinged to each other through a rotating shaft 46, and both ends of the rotating shaft 46 are rotatably connected with running wheels 47. The rotating shaft 46 connects the adjacent ends of the support plates 45 together, and installs the running wheels 47, so that the running wheels 47 rotate about the axis of the rotating shaft 46. When the two groups of slide plates 41 move in opposite directions, the support plate 45 drives the rotating shaft 46 to move downward, so that the running wheels 47 contact the ground and support the logistics box as a whole, so as to facilitate the movement of the logistics box as a whole. When the two groups of slide plates 41 move toward each other, the support plate 45 drives the rotating shaft 46 to move upward, and the running wheels 47 are stored in the storage groove 3, and the base 1 contacts the ground, so that the logistics box as a whole stands stably on the ground.

[0034] Reference 1- Figure 2 , Figure 4 The side wall of the top cover 2 is provided with a limit assembly 5, which is used to limit the height of the top cover 2. The limit assembly 5 includes a positioning pin 51, which penetrates and is slidably connected to the side wall of the top cover 2. The positioning pin 51 is inserted into the inside of the positioning hole 12. The positioning pin 51 is used to limit the up and down movement of the top cover 2 to ensure that the top cover 2 maintains a corresponding height. The end of the positioning pin 51 is fixedly connected to a connecting plate 52, and the end of the connecting plate 52 is fixedly connected to a cross plate 53. The connecting plate 52 and the cross plate 53 are used to transfer the tension of the reset spring 56 to the end of the positioning pin 51, so that the position of the positioning pin 51 remains stable. The front of the box body 11 is fixedly connected to a guide plate 54, and the cross plate 53 is slidably connected to the inside of the guide plate 54. The guide plate 54 is used to provide a guiding effect for the cross plate 53, so that the cross plate 53 can move horizontally stably.

[0035] Reference 1- Figure 2 , Figure 4The end of the cross plate 53 is fixedly connected with an end plate 55, and the two groups of end plates 55 are elastically connected by a return spring 56. The end plate 55 is used to provide a support point for the return spring 56. The return spring 56 is in a stretched state. Through the pulling force of the return spring 56, the two groups of positioning pins 51 are controlled to be stably inserted into the positioning holes 12 to fix the height of the top cover 2. At the same time, by controlling the two groups of end plates 55 to move backwards, the return spring 56 is stretched again, and the cross plate 53 and the connecting plate 52 drive the positioning pin 51 to separate from the positioning hole 12, thereby facilitating the release of the limit on the top cover 2 and facilitating the adjustment of the height of the top cover 2.

[0036] Working principle: When the logistics box needs to be moved from one place to another, the operator only needs to gently rotate the brake wheel 43. Through the drive of the bidirectional threaded rod 42, the two sets of slide plates 41 will move in opposite directions, driving the support plate 45 and the rotating shaft 46 to move downward, and finally making the running wheel 47 contact the ground. At this time, the weight of the logistics box is supported by the running wheel 47, so it can be moved easily.

[0037] When the logistics box needs to be placed stably on the ground, the brake wheel 43 is rotated again to make the two sets of slides 41 move toward each other, and the support plate 45 and the rotating shaft 46 move upward accordingly. The walking wheel 47 is stored in the storage groove 3, and the bottom surface of the base 1 contacts the ground, and the logistics box stands stably on the ground.

[0038] When adjusting the height of the top cover 2, the operator can push the end plate 55 to move backward, the return spring 56 is stretched, and at the same time the cross plate 53 and the connecting plate 52 drive the positioning pin 51 to be pulled out of the positioning hole 12, thereby releasing the limit on the top cover 2. At this time, the top cover 2 can freely adjust its height along the outer wall of the box body 11. When the top cover 2 is adjusted to a suitable height, the end plate 55 is released, and the tension of the return spring 56 causes the positioning pin 51 to be reinserted into the corresponding positioning hole 12, and the height of the top cover 2 is fixed.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
