Description

Technical Field

[0001] This utility model relates to the field of gravity flow racks with adjustable slope, and more particularly to a gravity flow rack with adjustable slope. Background Technology

[0002] With the rapid development of modern industry and logistics, the importance of warehousing has become increasingly prominent. Enterprises are placing higher demands on warehouse space utilization, goods storage, and turnover efficiency. Gravity flow racks, with their first-in, first-out (FIFO) storage method, effectively utilize space and facilitate goods access, and are widely used in the warehousing field.

[0003] Currently, the most common fixed gravity flow racks on the market adopt an integrated slope structure, which mainly consists of fixed tilt brackets, load-bearing beams and positioning rollers.

[0004] Existing traditional gravity flow racks generally use a fixed slope structure, which does not support slope adjustment. The fixed slope cannot match the sliding requirements of goods of different weights and sizes. In addition, the exit baffle is a fixed design, which can obstruct passage when it cannot be retracted. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable slope gravity rack, which aims to improve the problems of existing technology that do not support slope adjustment, fixed slope cannot match the sliding needs of goods of different weights and sizes, and the exit baffle is a fixed design that can obstruct passage when it cannot be retracted.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable slope gravity rack, comprising a support frame, a drive shaft fixedly connected inside the support frame, a guardrail rotatably connected outside the drive shaft, multiple rollers rotatably connected inside the guardrail, a motor fixedly connected outside the support frame, a lead screw fixedly connected to the output end of the motor, two threaded sleeves threadedly connected outside the lead screw, a U-shaped frame rotatably connected outside each of the two threaded sleeves, a support plate rotatably connected between the tops of the two U-shaped frames, and two crossbeam supports abutting at the bottom of the support plate;

[0007] As a further description of the above technical solution: two pressing plate drive shafts are slidably connected to the outside of the end of the guardrail away from the support plate. A limit block is fixedly connected between the bottom of the two pressing plate drive shafts. A pin is fixedly connected to the top of the limit block. A baffle support shaft is slidably connected to the outside of the pin. A baffle is fixedly connected to the outside of the baffle support shaft. A spring is sleeved on the outside of both pressing plate drive shafts. A pressing plate is fixedly connected between the top of the two pressing plate drive shafts.

[0008] As a further description of the above technical solution: both of the crossbeam supports are fixedly connected inside the support;

[0009] As a further description of the above technical solution: the two ends of the baffle rotate inside the guardrail, and the outer side of the baffle abuts against the inner side of the guardrail;

[0010] As a further description of the above technical solution: the support plate is slidably connected inside the bracket, and the lead screw is rotatably connected inside the bracket;

[0011] As a further description of the above technical solution: the outer side of the guardrail is slidably connected to the inner side of the bracket;

[0012] As a further description of the above technical solution: the end of the guardrail away from the baffle abuts against the top of the support plate;

[0013] As a further description of the above technical solution: one end of the spring is fixedly connected to the top of the guardrail, and the other end of the spring is fixedly connected to the bottom of the pressing plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, after the motor starts, its output end drives the lead screw to rotate. Since the lead screw and the threaded sleeve are threadedly connected, the threaded sleeve will move axially on the lead screw. The U-shaped frame rotatably connected to the outside of the threaded sleeve will move with the threaded sleeve. The support plate slidably connected to the top of the U-shaped frame will slide along the inside of the support under the push of the U-shaped frame, thereby changing the height of the support plate and the structure connected to it, and realizing the adjustment of the slope of the shelf.

[0016] 2. In this utility model, when the baffle needs to be operated, pressing the pressing plate causes the pressing plate drive shaft to move the limiting block and the pin rod downwards, compressing the spring. The pin rod disengages from the limiting position of the baffle support shaft, at which point the baffle support shaft can rotate between the two pressing plate drive shafts, realizing the rotation operation of the baffle and achieving opening and retraction. After releasing the pressing plate, the spring returns to its original position, and the pin rod re-inserts into the corresponding position of the baffle support shaft, limiting and fixing the baffle. This allows the baffle to rotate 90 degrees and lie flat when not needed, effectively solving the problem of traditional baffles obstructing the passage when they cannot be retracted.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of an adjustable slope gravity-fed shelving unit, comprising a support frame 2. A drive shaft 10 is fixedly connected inside the support frame 2, and a guardrail 1 is rotatably connected to the outside of the drive shaft 10. Multiple rollers 9 are rotatably connected inside the guardrail 1, providing support and rolling conditions for goods to slide on the shelving unit, facilitating the movement of goods under gravity according to the slope of the shelving unit. A motor 8 is fixedly connected to the outside of the support frame 2, and a lead screw 5 is fixedly connected to the output end of the motor 8. Two threaded sleeves 6 are threadedly connected to the outside of the lead screw 5, and U-shaped frames 7 are rotatably connected to the outside of each of the two threaded sleeves 6. A support plate 3 is rotatably connected between the tops of the two U-shaped frames 7, and two crossbeam supports 4 abut against the bottom of the support plate 3. The two crossbeam supports 4 are fixedly connected inside the support frame 2, and the support plate 3 is slidably connected inside the support frame 2. When the motor 8 is started, its output end drives the lead screw 5 to rotate, causing the threaded sleeves 6 to move axially along the lead screw 5. The U-shaped frames 7 move with the threaded sleeves 6, pushing the support plate 3 to slide along the inside of the support frame 2, changing the height of the support plate 3 and its connected structures, thereby achieving slope adjustment of the shelving unit. The lead screw 5 is rotatably connected to the inside of the bracket 2, the outer side of the guardrail 1 is slidably connected to the inner side of the bracket 2, and the end of the guardrail 1 away from the baffle 11 abuts against the top of the support plate 3.

[0024] Reference Figure 3Two pressing plate drive shafts 12 are slidably connected to the outer side of the guardrail 1 away from the support plate 3. A limit block 16 is fixedly connected between the bottoms of the two pressing plate drive shafts 12. A pin rod 15 is fixedly connected to the top of the limit block 16. A baffle support shaft 17 is slidably connected to the outside of the pin rod 15. A baffle 11 is fixedly connected to the outside of the baffle support shaft 17. A spring 13 is sleeved on the outside of each of the two pressing plate drive shafts 12. A pressing plate 14 is fixedly connected between the tops of the two pressing plate drive shafts 12. One end of the spring 13 is fixedly connected to the top of the guardrail 1. The other end of 13 is fixedly connected to the bottom of the pressing plate 14. When the baffle 11 is operated, the pressing plate 14 is pressed, and the pressing plate drive shaft 12 drives the limiting block 16 and the pin rod 15 to move down, compressing the spring 13. The pin rod 15 disengages from the baffle support shaft 17 and can rotate between the pressing plate drive shaft 12 to realize the opening and closing of the baffle 11. This ensures that the baffle can be stably maintained in the set position when it is not needed to operate, thus ensuring the safety and stability of the goods during storage. When the pressing plate 14 is released, the spring 13 returns to its original position, and the pin rod 15 is inserted into the corresponding position of the baffle support shaft 17 to limit and fix the baffle 11.

[0025] Working principle: When motor 8 starts, its output end drives screw 5 to rotate. Threaded sleeve 6 moves axially along screw 5, and U-shaped frame 7 moves with threaded sleeve 6, pushing support plate 3 to slide inside bracket 2, changing the height of support plate 3 and connected structures to adjust the shelf slope. When operating baffle 11, pressing press plate 14 causes press plate drive shaft 12 to move limit block 16 and pin rod 15 downwards, compressing spring 13. Pin rod 15 disengages from baffle support shaft 17, allowing baffle support shaft 17 to rotate between press plate drive shaft 12, opening and closing baffle 11. This ensures that the baffle remains stably in the set position when not in use, guaranteeing safety and stability during goods storage. Releasing press plate 14 resets spring 13, and pin rod 15 inserts into the corresponding position on baffle support shaft 17, fixing baffle 11. Roller 9 rotates inside guardrail 1, providing support and rolling conditions for goods to slide on the shelf, facilitating movement of goods according to the shelf slope under gravity. When the slope of the shelf is adjusted to change the height of one end of the guardrail 1, the drive shaft 10 passes through the guardrail 1 and rotates, ensuring that the guardrail 1 rotates smoothly and adjusts its posture, preventing the other end from getting stuck when one end is raised or lowered.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
