[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0040] See also Figure 1-6As shown, the present invention is a logistics storage shelf, including a bracket and a support plate 10 installed on the bracket and used for placing express and other goods. The provided bracket includes four columns 1 distributed in a rectangular shape, and a crossbeam A101, a longitudinal beam A102 and a diagonal brace 11 connected between two columns 1 located on the same side. In order to avoid the existence of the crossbeam A101 to hinder the taking of express and other goods, the support plate 10 and the crossbeam 101 and the longitudinal beam 102 arranged in the present invention are in a one-to-one correspondence, and the upper surface of the support plate 10 is not lower than the upper surface of the crossbeam 101, and the upper surface of the support plate 10 is not lower than the upper surface of the longitudinal beam 102.

[0041] That is, it is necessary to know that in order to meet the purpose of the application of the present invention to block express and other goods placed on the support plate 10 and prevent express and other goods on the support plate 10 from slipping, a liftable blocking rod 2 is installed on the columns 1 located on both sides of the support plate 10.

[0042] Specifically, Figure 2-3 The blocking rod 2 provided by the present invention includes a rectangular rod 20, and the two ends of the rectangular rod 20 are provided with a bend 21 that is clamped on one side of the column 1, and the end of the bend 21 is provided with a limiting portion 22 that is clamped on one side of the column 1. The setting of the above-mentioned blocking rod 2 structure prevents the blocking rod 2 from detaching from one side of the bracket; at the same time, a support block 24 is welded on the side wall of the column 1 located directly below the bend 21, and a threaded hole A is opened on the bend 21 along the setting direction, and an external threaded sleeve 231 is threadedly connected at the threaded hole A, and the top of the external threaded sleeve 231 is connected to a limiting ring 23, and a spring A25 is connected between the support block 24 and the bend 21 and is sleeved on the outside of the external threaded sleeve 231. The support block 24 is provided with a through hole 240 for the external threaded sleeve 231 to pass through, and then the blocking rod 2 is controlled to move downward by external force when in use. At this time, after the blocking rod 2 is controlled to move downward, the positional relationship between the external threaded sleeve 231 and the support block 24 is fixed.

[0043] Based on the above-mentioned positional relationship fixing requirement, in a possible implementation, a limiting mechanism is provided on the support block 24 to limit the position of the external threaded sleeve 231 passing through the through hole 240 .

[0044] It is known that if Figure 10-13The specific limiting mechanism includes two through holes 232 opened on the external threaded sleeve 231, and a rectangular channel 233 is formed between the two through holes 232; an installation cavity 241 is provided on an inner side wall of the through hole 240, and a convex column 242 is provided on the side wall of the installation cavity 241, and the end of the convex column 242 is connected to a column sleeve 244 sleeved on the convex column 242 through a spring C243, and the end of the column sleeve 244 is connected to a control rod 245, and a through hole 241 is provided on the inner side wall of the through hole 240 facing the installation cavity 241. 8, the control rod 245 passes through the through hole 248; the sleeve rod 13 is provided with a rectangular hole along the length direction, and the column sleeve 244 is inserted into the rectangular hole, that is, when it is necessary to control a certain blocking rod 2 to move downward during use, first control the column sleeve 244 to be compressed until it is completely received in the mounting cavity 241, and then the external force is used to control the blocking rod 2 to move downward, and then the column sleeve 244 is controlled to extend out of the mounting cavity 241 and inserted into a through hole 232. At this time, when the external force is removed, the blocking rod 2 will not move upward under the action of the spring A25.

[0045] In order to meet the above functions, it should be noted that the diameter of the through hole 232 is larger than the width of the rectangular channel 233, the diameter of the column sleeve 244 is between the diameter of the through hole 232 and the width of the rectangular channel 233; the diameter of the control rod 245 is smaller than the width of the rectangular channel 233; the width of the rectangular hole is larger than the diameter of the column sleeve 244.

[0046] At the same time, on the basis of the above, in order to facilitate the control of the control rod 245, after pressing, the column sleeve 244 is always completely received in the installation cavity 241. Figure 12-13 In the present invention, a convex tube 246 is arranged on the outer wall of the support block 24 at the through hole 248, and a tube sleeve 247 is movably sleeved on the end of the convex tube 246, and a spring D249 is connected between the tube sleeve 247 and the outer wall of the support block 24; a threaded structure A2471 is arranged on the inner wall of the open end of the tube sleeve 247, and a threaded structure B2461 threadedly matched with the threaded structure A2471 is arranged on the outer peripheral side wall of the convex tube 246, and the end of the control rod 245 is against the inner bottom side of the tube sleeve 247. When it is necessary to control the control rod 245 to be pressed, an external force is first used to control the tube sleeve 247 to be pressed, thereby causing the tube sleeve 247 to move toward one side of the support block 24, and then the threaded structure A2471 is controlled to be threadedly connected with the threaded structure B2461. At this time, when the external force controlling the tube sleeve 247 is removed, the tube sleeve 247 will not rebound under the action of the spring D249.

[0047] At the same time, in the present invention, all the blocking rods 2 are controlled to move up and down in the vertical direction under certain usage conditions. The present invention installs a driving mechanism on the bracket to control the driving blocking rods 2 to move up and down in the vertical direction, such as Figure 2-6, and then the driving mechanism includes a protrusion 12 arranged on the top of the column 1, protruding to one side and located just above the bend 21, the bottom side of the protrusion 12 is connected to the sleeve 121, and the bottom side of the sleeve 121 is connected to a sleeve rod 13 sliding along the inner wall of the sleeve 121 through a spring B, the sleeve rod 13 passes through the external threaded sleeve 231, and a limiting ring 131 is welded on the outer peripheral side wall of the sleeve rod 13 above any external threaded sleeve 231; a traction rope 130 is connected between the bottom ends of the two sleeve rods 13 located at the same end of the support plate 10, and a guide block 14 for the traction rope 130 to pass through is welded on the side wall of the column 1 just below the sleeve rod 13, and further It includes a driving structure that controls the downward movement of the blocking rod 2 through a traction rope 130; when in use, the two driving structures are controlled by the control driving structure to perform a tensioning effect. At this time, the traction rope 130 is used to control the sleeve rod 13 to move downward, and the limit ring 131 is used to abut against the upper surface of the bend 21, and then the sleeve rod 13 moves downward to control all the blocking rods 2 to move downward synchronously. When the traction rope 130 is controlled to restore to the initial state, under the action of spring B and spring A25, the blocking rod 2 and the sleeve rod 13 are restored to their initial positions. At this time, the blocking rod 2 is used to block the goods from falling off the support plate 10.

[0048] In order to better control the downward movement of the barrier rod 2 by controlling the traction rope 130, as Figure 4-5 The driving structure provided by the present invention comprises a pair of cross beams B16 whose two ends are respectively welded on two upright columns 1, and a longitudinal beam B161 and a longitudinal beam C162 are welded and connected between the two cross beams B16; the two traction ropes 130 are connected to the connecting piece 3; a telescopic cylinder 17 and a fixed pulley 18 that are telescopic in the horizontal direction are fixed to a side of the longitudinal beam B161 close to the longitudinal beam C162, and a longitudinal rod 171 is connected to the end of the telescopic cylinder 17, and the two ends of the longitudinal rod 171 are respectively connected to the control rope A151 and the control rope B1 52; one end of the control rope A151 passes through the longitudinal beam B161 and is connected to a connecting piece 3; one end of the control rope B152 passes through the fixed pulley 18 and the longitudinal beam C162 and is connected to another connecting piece 3; a guide rod 172 is provided on the longitudinal rod 171, and a guide hole matching the guide rod 172 is provided on the longitudinal beam C162. Then, when the telescopic cylinder 17 is extended, the telescopic cylinder 17 is used to control the two traction ropes 130, and synchronously control the sleeve rods 13 on both sides to move downward.

[0049] During use, there is a possibility that after placing the goods on the upper part of the support plate 10, the control rod 2 is forgotten to synchronously restore to the initial position. Therefore, the present invention is also provided with a detection mechanism A for detecting the extension length of the telescopic cylinder 17. The detection mechanism A includes an infrared distance sensor arranged on the longitudinal beam C162 and facing the longitudinal rod 171. The infrared distance sensor is connected to the controller. The controller is connected to the alarm, and a detection mechanism B is arranged on the support plate 10 and detects whether there is goods placed on the support plate 10. After the goods are arranged on the support plate 10, the detection mechanism B is used to detect whether there is goods placed on the support plate 10. At the same time, the setting of the detection mechanism A is used to determine the position of the baffle rod 2 by detecting the extension length of the telescopic cylinder 17. When the telescopic cylinder 17 is extended to the specified length, the baffle rod 2 completes the downward movement and the upper surface of the baffle rod 2 is lower than the upper surface of the support plate 10. When the telescopic cylinder 17 is retracted to the specified length, the baffle rod 2 completes the upward movement and the upper surface of the baffle rod 2 is higher than the upper surface of the support plate 10.
