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.

[0032] Reference Figure 1-Figure 3The utility model provides an embodiment of a height-adjustable logistics shelf, including a support frame 1, a circular groove 2 is provided on the inner wall of the support frame 1, two circular grooves 2 are provided, which are respectively arranged on the lower inner wall and the middle inner wall of the support frame 1, the circular groove 2 is circular in shape, and the positioning block 5 matches it, and the inner wall of the support frame 1 is slidably connected with a sliding block 4, and the inner wall of the support frame 1 is provided with a notch, which matches the sliding block 4 to meet the vertical movement of the sliding block 4 along the support frame 1, and the inner wall of the sliding block 4 is provided with a positioning mechanism, and the positioning mechanism is respectively divided diagonally on the left and right sides of the cargo plate 13. The left side wall of the sliding block 4 is hinged with a connecting frame 14 through a hinge rod 12. The connection between the connecting frame 14 and the hinge rod 12 is open to meet the movement trajectory of the hinge rod 12 during use. The right outer wall of the support frame 1 is fixedly connected with a sliding frame 15. The inner wall of the sliding frame 15 is slidably connected with a fixed block 7. The right end of the fixed block 7 is fixedly connected with a cargo plate 13. The four corners of the cargo plate 13 are respectively provided with fixed blocks 7 to facilitate the up and down movement of the cargo plate 13. The positioning mechanism includes a positioning block 5, which is slidably connected to the inner wall of the sliding block 4. The positioning block 5 is cylindrical and The right end is arranged in an inclined surface, and when the inclined surface is squeezed, the positioning block 5 will slide in the sliding block 4. The left end of the positioning block 5 is fixedly connected with the cylindrical block 3. The outer surface of the left end of the support frame 1 is provided with a groove of a certain length and matches the cylindrical block 3. The inner wall of the left end of the sliding block 4 is elastically connected with the positioning block 5 through a positioning spring 6. The inner wall of the sliding block 4 is provided with a groove, and the groove matches the positioning block 5. The positioning block 5 is inserted into the inner wall of the circular groove 2. The inner wall of the left end of the sliding block 4 is fixedly connected with one end of the positioning spring 6, and the other end of the positioning spring 6 is fixedly connected with the inner side wall of the positioning block 5. When the positioning block 5 slides on the inner wall of the sliding block 4, the positioning spring 6 will be compressed. When resetting, the elastic force of the positioning spring 6 will be used to clamp the positioning block 5 on the inner wall of the circular groove 2. The left side wall of the sliding block 4 is hinged to one end of the hinged rod 12, and the other end of the hinged rod 12 is hinged to the inner wall of the connecting frame 14. The length of the hinged rod 12 is constant. When the connecting frame 14 moves one end of the hinged rod 12 to the right, the other end of the hinged rod 12 will move the sliding block 4 downward. When the connecting frame 14 moves one end of the hinged rod 12 to the left, the other end of the hinged rod 12 will move the sliding block 4 upward.

[0033] Reference Figure 4-Figure 6The inner wall of the fixed block 7 passes through and is slidably connected with a movable block 8, and a card block 9 is fixedly connected to the front end of the movable block 8. There is a square plate connected between the movable block 8 and the card block 9, which is U-shaped. Two groups of card blocks 9 are provided, and the two groups of card blocks 9 are elastically connected by a reset spring 11. The two groups of card blocks 9 are close to each other, which will compress the reset spring 11. When resetting, the elastic force of the reset spring 11 is used to reset the two groups of card blocks 9. Multiple groups of square grooves 10 are provided on both sides of the sliding frame 15, and the square grooves 10 match the fixed block 7. The card block 9 is plugged into the inner wall of the square groove 10. The inner wall of the fixed block 7 is provided with a notch to facilitate the movement of the movable block 8 and the card block 9. The card block 9 passes through and is slidably connected to the inner wall of the fixed block 7. Two groups of cargo plates 13 are provided, and the two groups of cargo plates 13 slide relative to each other.

[0034] Working principle: When the support frame 1 and the connecting frame 14 need to be folded, the cylindrical block 3 is manually moved outward. When the cylindrical block 3 moves, it drives the positioning block 5 to slide on the inner wall of the sliding block 4. At this time, the positioning spring 6 is in a compressed state, so that the positioning block 5 is separated from the upper circular groove 2 and the support frame 1 and the connecting frame 14 are brought together. At this time, one end of the hinged rod 12 rotates downward on the inner wall of the connecting frame 14, and the other end of the hinged rod 12 drives the sliding block 4 to slide downward along the inner wall of the support frame 1. When the sliding block 4 slides to the lower end of the support frame 1, the cylindrical block 3 is released and the elastic force of the positioning spring 6 is used to allow the positioning block 5 to be clamped on the inner wall of the lower circular groove 2 of the support frame 1. The support frame 1 and the connecting frame 14 are brought together and drive the cargo plate 13 to slide and retract.

[0035] When the support frame 1 and the connecting frame 14 need to be unfolded and used, it is only necessary to manually move the support frame 1 and the connecting frame 14 apart from each other. At this time, one end of the hinged rod 12 rotates upward on the inner wall of the connecting frame 14, and the other end of the hinged rod 12 drives the sliding block 4 to slide upward along the inner wall of the support frame 1. At this time, the right end of the positioning block 5 is squeezed and slides on the inner wall of the sliding block 4, and the positioning spring 6 is in a compressed state. When the positioning block 5 reaches the upper end circular groove 2 of the support frame 1, the reverse elastic force of the positioning spring 6 is used to make the positioning block 5 inserted into the inner wall of the upper end circular groove 2.

[0036] When the height of the cargo plate 13 needs to be adjusted, manually press the movable block 8 to move it inward, and the movable block 8 slides on the inner wall of the fixed block 7 while driving the card block 9 to move together. At this time, the return spring 11 is in a compressed state. According to the required placement space for the goods, the height of the cargo plate 13 is adjusted, and the fixed block 7 moves up and down with the cargo plate 13. According to the position of the square groove 10, the cargo plate 13 is adjusted to a specified height. Release the movable block 8 and use the reverse elastic force of the return spring 11 to make the card block 9 plug into the inner wall of the square groove 10 to complete the height adjustment of the cargo plate 13.

[0037] 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.
