One end of the rack 6 is fixedly connected with a retaining bar 5 that prevents the goods from tipping over. The inner wall of the retaining bar 5 is provided with a hole for the rack 6 and the fixing bar 4 to pass through. One side of the retaining bar 5 is fixedly connected with two fixing bars 4, and the fixing bars 4 on the inner side of the retaining frame 3 are staggered up and down.

[0032] An extrusion assembly for extruding the extrusion plate 7, the extrusion assembly includes a first extrusion rod 15 and two extrusion cylinders 10 for extruding the extrusion cylinders 15, one end of the first extrusion rod 15 away from the extrusion cylinder 10 is fixedly connected to the baffle frame 3 and the outer side of the first extrusion rod 15 is sleeved with a second spring for resetting the first extrusion rod 15, the extrusion cylinder 10 is U-shaped, and one end connected to the second extrusion rod 16 is arranged above the baffle frame 3, one end of the first extrusion rod 15 passes through the support assembly 9 and is slidably connected to the inner side of one end of the extrusion cylinder 10, the inner side of the other end of the extrusion cylinder 10 is fixedly connected to a ring 19 for limiting the movement of the first spring, the surface of the ring 19 is fixedly connected to the first spring for resetting the first extrusion rod 16, the end of the first spring away from the ring 19 is fixedly connected to the second extrusion rod 16, the surface of the second extrusion rod 16, etc. There are perforations at intervals, and the bottom of the extrusion rod is fixedly connected to a fixed plate 8, and the middle part of the fixed plate 8 is slidably connected to a moving column 11, and the bottom of the moving column 11 is fixedly connected to an extrusion plate 7 for limiting the top of the cargo, and both sides of the top of the extrusion plate 7 are fixedly connected to sliding rods 17 that stabilize the extrusion plate 7, and the top of the sliding rod 17 passes through the inner wall of the fixed plate 8 and is fixedly connected to the adjusting component 12, and both sides of the top of the moving column 11 are fixedly connected to the adjusting component 12 for adjusting the initial position of the extrusion plate 7, and the adjusting component 12 includes an insert rod 121 and a sleeve 122, one end of the insert rod 121 abuts against the through hole opened on the surface of the second extrusion rod 16, and the other end of the insert rod 121 is slidably connected in the sleeve 122, and the side of one end of the insert rod 121 is fixedly connected with a pull rod, and the pull rod passes through the square groove opened on the side of the sleeve 122.

[0033] The implementation principle of a forklift shelf blocking assembly in the embodiment of the present application is: turn on the motor 13, and the rack 6 is driven to move by the rotation of the motor 13, and the movement of the rack 6 drives the blocking bar 5 to move, and the movement of the blocking bar 5 is used to adjust the width of the goods to be blocked. Since one side of the blocking bar 5 is fixedly connected to the fixed bar 4, the blocking bar 5 can move stably, and by pulling the pull rod, the insertion rod 121 is disengaged from the through hole opened on the surface of the second extrusion rod 16, so that the initial position of the extrusion plate 7 is adapted to the approximate height of the goods.

[0034] After adjusting the width and height, the forklift drives the fork 1 to lift the goods. As the forklift moves, the goods move toward the baffle frame 3. When the goods squeeze the baffle frame 3, the baffle frame squeezes the mounting rod 14 and the first squeezing rod 15 so that the first squeezing rod 15 squeezes the extrusion cylinder 10. The first squeezing rod 15 squeezes the extrusion cylinder 10 so that the air in the extrusion cylinder 10 is squeezed. The air in the extrusion cylinder 10 is squeezed so that the second squeezing rod 16 moves downward. The downward movement of the second squeezing rod 16 causes the extrusion plate 7 and the fixing plate 8 to move downward to limit the goods.

[0035] When unloading, after placing the goods on the shelf, the forklift moves backward to keep the goods away from the blocking frame 3. Since springs are provided on the outer sides of the mounting rod 14 and the first extrusion rod 15, the blocking frame 3 can be automatically reset. The air pressure in the extrusion cylinder 10 returns to its original state through the reset of the blocking frame 3. The air pressure in the extrusion cylinder 10 returns to its original state, and the second extrusion rod 16 is reset through the reset of the second extrusion rod 16. The extrusion plate 7 is reset through the reset of the second extrusion rod 16.
