[0007] The width adjustment mechanism includes a first driving device, a traction sliding rod, and a second driving device. A double-ended threaded rod is provided on the output shaft of the first driving device. Both ends of the double-ended threaded rod are provided with linkage support members that can be horizontally driven by the double-ended threaded rod. Support sliders are provided at the top of both ends of the linkage support members. The cargo railing stands vertically on the top of the support sliders.

[0008] The support sliders on the same side of the two linkage support members are both penetrated by the same traction sliding rod, and the support sliders can slide along the axial direction of the traction sliding rod;

[0009] The output end of the second drive device is provided with a transmission belt, which is arranged in a cross pattern with the double-headed threaded rod. The transmission belt can drive the traction sliding rods on both sides to move in opposite directions.

[0011] Preferably, the helical directions of the threads at both ends of the double-ended threaded rod are opposite, and a gap is provided between the threads on both sides located at the center of the double-ended threaded rod.

[0012] Preferably, the linkage support includes a central connecting rod, the axis of which is threadedly connected to a double-threaded rod, and both ends of the central connecting rod are provided with support sleeves, each of which can slide along the axial direction of the central connecting rod;

[0013] Each of the linkage support components has a stabilizing support rod arranged parallel above it. The stabilizing support rod passes through two support sliders respectively, and the support sliders can slide on the surface of the stabilizing support rod.

[0014] Preferably, the traction sliding rod includes a smooth rod body, and traction sliders are provided at both ends of the smooth rod body. Each traction slider is placed inside a limiting groove, and the traction slider can slide inside the limiting groove.

[0015] Preferably, the outer surface of the smooth rod is provided with a connecting plate, and the connecting plates of the two sides of the smooth rod are respectively located on both sides of the transmission belt and connected to the transmission belt.

[0038] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0039] Please see Figures 1 to 7 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0040] like Figures 1-3 As shown, this utility model provides a height-adjustable width automatic pallet warehouse, including a base mechanism 1, which is a hollow quadrilateral support. The base mechanism 1 has a width adjustment mechanism 2 inside, which supports multiple cargo railings 3. The width adjustment mechanism 2 drives the cargo railings 3 to change the spacing between them, thereby adapting to goods of different sizes and providing stable support for the goods.

[0041] Specifically, the width adjustment mechanism 2 includes a first drive device 21, a traction sliding rod 25, and a second drive device 26. Both the first drive device 21 and the second drive device 26 are servo motors and can be controlled by an external remote control or control device. The first drive device 21 is mounted on the surface of the base mechanism 1. A double-ended threaded rod 22 is provided on the output shaft of the first drive device 21. The other end of the double-ended threaded rod 22 is connected to the inner wall of the support base 11 on the side away from the first drive device 21, and the double-ended threaded rod 22 can be rotated by the drive of the first drive device 21. Both ends of the double-ended threaded rod 22 are provided with linkage support members 23 that can be horizontally driven by the double-ended threaded rod 22. Support sliders 24 are provided at the top of both ends of the linkage support members 23. Cargo railings 3 stand vertically on the top of the support sliders 24, and all cargo railings 3 form a rectangle for supporting and limiting the cargo.

[0042] The support sliders 24 on the same side of the two linkage support members 23 are both penetrated by the same traction sliding rod 25, thereby supporting the linkage support members 23 and preventing them from rotating along the double-threaded rod 22. Furthermore, the support sliders 24 can slide along the axial direction of the traction sliding rod 25 to change the spacing between the cargo guardrails 3.

[0043] The output end of the second drive device 26 is equipped with a transmission belt 27, which is arranged in a cross shape with the double-threaded rod 22. When the second drive device 26 drives the transmission belt 27 to move, the transmission belt 27 can drive the traction sliding rods 25 on both sides to move in opposite directions, thereby further changing the spacing between the cargo guardrails 3, so that the cargo guardrails 3 can move along the X and Y axes, increasing the richness of width adjustment.

[0044] like Figure 3 and Figure 4 As shown, in some embodiments, the base mechanism 1 of this utility model includes a support base 11, which serves as the base of the entire device and supports the entire device. The middle part of the support base 11 is hollow, used to install and support the width adjustment mechanism 2. Limiting grooves 12 are provided on two symmetrical sides of the support base 11. The two ends of the traction sliding rod 25 are respectively located in the limiting grooves 12 on both sides and can slide therein, so that the traction sliding rod 25 can move smoothly, and at the same time, the limiting grooves 12 support the traction sliding rod 25 to improve the load-bearing capacity of the traction sliding rod 25.

[0045] like Figure 2As shown, in some embodiments, the helical directions of the threads at both ends of the double-threaded rod 22 of this invention are arranged opposite to each other. When the double-threaded rod 22 rotates, the linkage support members 23 connected to the threads at both ends of the double-threaded rod 22 can move in opposite directions, thereby increasing or decreasing the distance between the cargo railings 3. A gap is provided at the center of the threads on both sides of the double-threaded rod 22 to limit the movement position of the linkage support members 23 on both sides, preventing the linkage support members 23 on both sides from moving excessively and colliding with each other.

[0046] like Figure 6 As shown, in some embodiments, the linkage support member 23 of this utility model includes a central connecting rod 231, the axis of which is threadedly connected to a double-threaded rod 22, thereby enabling the central connecting rod 231 to move along the axis of the double-threaded rod 22 under the drive of the double-threaded rod 22. Support sleeves 232 are provided at both ends of the central connecting rod 231, and each support sleeve 232 can slide along the axial direction of the central connecting rod 231. When the traction sliding rod 25 is driven to move by the transmission belt 27, the support sleeves 232 avoid movement interference by sliding on the outer surface of the central connecting rod 231. Furthermore, the structure formed by the central connecting rod 231 and the support sleeves 232 can support the traction sliding rods 25 at both ends, thereby improving the support strength for the goods.

[0047] A stabilizing support rod 28 is arranged parallel above each linkage support member 23, and both ends of the stabilizing support rod 28 are fixedly connected to the inner wall of the support base 11. The stabilizing support rod 28 passes through two support sliders 24 respectively, and is used to further support the support sliders 24 to improve the support strength, reduce the pressure on the linkage support member 23, and the support sliders 24 can slide on the surface of the stabilizing support rod 28.

[0048] like Figure 5 As shown, in some embodiments, the traction sliding rod 25 of this invention includes a smooth rod body 251. The smooth rod body 251 has a smooth outer surface, allowing the supporting slider 24 to slide along the axial direction of the smooth rod body 251. Traction sliders 252 are provided at both ends of the smooth rod body 251. The traction sliders 252 are rectangular sliders, and each traction slider 252 is placed inside the limiting groove 12, allowing it to slide within the limiting groove 12. The upper and lower sides of the traction slider 252 are evenly overlapped with the inner walls of the limiting groove 12, thereby enabling the traction slider 252 to slide stably.

[0049] like Figure 5As shown, in some embodiments, the outer surface of the smooth rod 251 of this invention is provided with a connecting plate, which is set off from the axis of the smooth rod 251. The connecting plates of the two smooth rods 251 are respectively located on both sides of the transmission belt 27 and connected to the transmission belt 27 by bolts. When the transmission belt 27 rotates, the smooth rods 251 connected to both sides of the transmission belt 27 can move in relative directions.

[0050] like Figure 1 As shown, in some embodiments, a cargo pallet 4 is provided between the cargo guardrails 3 of this invention. The cargo pallet 4 is used to support external cargo, thereby allowing the cargo to be placed better between the cargo guardrails 3. The cargo pallet 4 can be separated from the cargo guardrails 3, allowing for easy separation. Different sizes of cargo pallets 4 can be adjusted to fit the spacing between the cargo guardrails 3. A lifting mechanism 5 is provided at the bottom of the cargo pallet 4, which drives the cargo pallet 4 to rise and fall, thereby changing the height of the cargo between the cargo guardrails 3. Especially when the pallet storage is located in a machine tool or assembly line, changing the height of the cargo makes it easier for a robotic arm to grasp the cargo.

[0051] like Figure 1 and Figure 3 As shown, in some embodiments, the top view of the cargo guardrail 3 of this utility model is L-shaped. The edges of the L-shape can effectively block the cargo and prevent it from sliding down between the two cargo guardrails 3 after piling up. A support platform is provided between the bottom of each cargo guardrail 3 and the top of the support slider 24. The cargo pallet 4 is placed on the support platform to prevent the cargo pallet 4 from directly contacting the traction sliding rod 25.

[0052] like Figure 1 As shown, in some embodiments, the four corners of the cargo pallet 4 of this utility model abut against the inner walls of the four cargo guardrails 3, thereby limiting the cargo pallet 4 by the cargo guardrails 3 and maintaining stability when the cargo pallet 4 is raised or lowered.

[0053] like Figure 2 and Figure 7 As shown, in some embodiments, the lifting mechanism 5 of this invention includes a lifting driver 51. The type of lifting driver 51 is configured according to requirements and can be a hydraulic, pneumatic, or other type of driver. A split-head pressure guide cylinder 52 is provided at the output end of the lifting driver 51. The split-head pressure guide cylinder 52 has multiple split heads for distributing the pressure in the lifting driver 51. A retractable telescopic head 53 is provided at the end of the split-head pressure guide cylinder 52, and the end of the telescopic head 53 abuts against the bottom of the cargo pallet 4. Supporting the cargo pallet 4 with multiple telescopic heads 53 improves the stability of the lifting and lowering of the cargo pallet 4. Changing the pressure in the split-head pressure guide cylinder 52 adjusts the degree of extension and retraction of the telescopic head 53, thereby changing the height of the cargo pallet 4.

[0054] In summary, the high-width adjustable automatic pallet storage of this utility model, by setting a first driving device 21 and a second driving device 26 on the base mechanism 1 respectively, drives the linkage support 23 and the traction sliding rod 25 to move, thereby changing the spacing between the cargo surrounding rods 3 on the support slider 24, thus changing the width inside the pallet and achieving the effect of conveniently adapting to goods of different sizes.

[0055] This utility model provides a lifting driver 51 at the bottom of the base mechanism 1. The lifting driver 51 is connected to an external control device. The lifting driver 51 generates power to drive the telescopic head 53 in the split-head pressure cylinder 52 to extend and retract, thereby driving the cargo pallet 4 to adjust its height between the cargo railings 3. This achieves the effect of automatically adjusting according to the stacking height of the cargo.

[0056] This utility model provides support for the support slider 24 by setting a central connecting rod 231 and providing support sleeves 232 that can slide along the central connecting rod 231 at both ends. Thus, the weight of the goods can be supported by the cooperation of the central connecting rod 231 and the support sleeves 232, and the strength of the pallet can be improved while the traction sliding rod 25 can be moved.

[0057] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0058] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
