[0043] A support plate 1, the support plate 1 has a plurality of insertion slots 2, and the support plate 1 is used to support items;

[0044] The baffles 3 are provided in a plurality, each of which has a plurality of plug-in ends 4, and the baffles 3 are respectively used to be plugged into the plug-in slots 2 through the plug-in ends 4, and are distributed around the supporting plate 1, and the baffles 3 and the supporting plate 1 are arranged vertically;

[0045] An elastic plug 5 is arranged on the plug-in end 4 and is located in the plug-in slot 2;

[0046] The action member 6 is arranged on the plug-in end 4 and is used to squeeze or not squeeze the elastic plug 5 . After the action member 6 squeezes the elastic plug 5 , the elastic plug 5 is used to clamp the inner wall of the plug-in slot 2 .

[0047] In this embodiment, the cart of the utility model realizes the rapid plugging and fixing of the baffle 3 by the cooperation of the plug-in slot 2 on the support plate 1 and the plug-in end 4 on the baffle 3, without the need for additional tools or complicated operations, thus simplifying the structure and improving the convenience of use. Since the baffle 3 can be adjusted along the four sides of the support plate 1 as needed, the cart of the utility model can adapt to the loading requirements of items of different sizes and shapes, providing higher flexibility. The elastic plug 5 on the baffle 3 can firmly clamp the inner wall of the plug-in slot 2 of the support plate 1 under the extrusion of the action member 6, thereby ensuring the stability of the baffle 3 during transportation and preventing the baffle 3 from loosening or displacement. The design of the action member 6 allows the user to squeeze or release the elastic plug 5 by simple manual operation, thereby realizing the rapid fixing and adjustment of the baffle 3 and improving the use efficiency of the cart. Since the fixing mechanism of the baffle 3 relies on the clamping action of the elastic plug 5, the use of mechanical devices is reduced, thereby reducing the safety risks caused by mechanical failures. Since the cart of the utility model reduces the use of mechanical parts, maintenance and cleaning become simpler, and the service life of the cart is extended.

[0048] Optionally, the plug end 4 has a first extrusion end 7, and the action member 6 includes:

[0049] A connecting rod 8 is threadedly disposed in the plug end 4, and an elastic plug 5 is disposed on the connecting rod 8 and is located near the first extrusion end 7. The first extrusion end 7 is used to extrude the elastic plug 5. After the connecting rod 8 rotates in the plug end 4, it is used to drive the elastic plug 5 to move closer to or away from the first extrusion end 7;

[0050] In this embodiment, through the threaded setting of the connecting rod 8, the user can accurately control the position of the elastic plug 5 and achieve fine-tuning of the fixing degree of the baffle 3 to meet the support requirements of items of different sizes. The rotation operation of the connecting rod 8 provides a simple and intuitive method to adjust the position and fixing state of the baffle 3. The user can quickly adjust it without using additional tools, which improves the convenience of operation. Since the position of the elastic plug 5 can be adjusted by rotating the connecting rod 8, the user can select the appropriate fixing strength according to actual needs, which enhances the adaptability and flexibility of the cart. The design of the first extrusion end 7 enables the connecting rod 8, the elastic plug 5 and the plug-in end 4 to form a compact structural unit, reducing space occupancy, making the cart more compact and convenient for storage and transportation. The threaded connection design improves the stability and durability of the fixing mechanism, reduces the wear that may occur due to frequent adjustments, and extends the service life of the cart.

[0051] Optionally, the plug end 4 has a first abutment end 9, and the action member 6 further includes:

[0052] The handle 10 is eccentrically and rotatably arranged on the connecting rod 8. The handle 10 has a second abutting end 11. After the handle 10 rotates, the first abutting end 9 and the second abutting end 11 abut against each other.

[0053] In this embodiment, the adjustable trolley of the utility model achieves a series of technical effects through the following technical solutions: the eccentric rotation design of the handle 10 allows the user to quickly fix and release the baffle 3 through a simple rotation action, thereby improving the efficiency of the operation. The eccentric rotation of the handle 10 provides a new adjustment mechanism, so that the position and fixing state of the baffle 3 can be adjusted more flexibly to meet the loading requirements of different items. The abutment design of the first abutment end 9 and the second abutment end 11 ensures the stability of the baffle 3 in the fixed state and reduces the potential risks caused by the loosening of the baffle 3. The design of the handle 10 provides an intuitive and easy-to-operate interface, and the user can easily fix and adjust the baffle 3, thereby improving the user experience. The design of the eccentric rotating handle 10 utilizes the principle of leverage, so that the force required by the user to adjust the baffle 3 is reduced, thereby reducing the labor intensity of the operation.

[0063] In this embodiment, the arrangement of the wheel assembly 12 allows the cart to be easily moved, improving the applicability and convenience of the cart in different environments. The design that the first mounting frame 13 and the second mounting frame 14 are respectively located at both ends of the support plate 1 increases the stability of the cart during movement and reduces the risk of tilting or tipping over. The arrangement of the wheels 15 allows the cart to be used under a variety of ground conditions, such as smooth indoor ground or uneven outdoor ground, improving the adaptability of the cart. The design of the bottom plate 16 and the side plate 18 allows the user to adjust the height of the baffle 3 by sliding the side plate 18, providing more adjustment options to meet the requirements of loading items of different heights. The sliding design of the first protrusion 19 of the side plate 18 in the first slide groove 17 makes the adjustment of the height of the baffle 3 simple and quick, and the user can easily operate it. The sliding mechanism of the wheel assembly 12 and the baffle 3 reduces the friction between the fixed parts, thereby extending the service life of the cart. The design of the wheel assembly 12 ensures the stability of the cart when moving, reducing the safety hazards caused by wheel failure or instability. The height adjustment function of the baffle plate 3 enables the trolley to be adapted to load items of different heights, thereby increasing the versatility of the trolley.

[0064] Optionally, the bottom plate 16 has a second slide groove 20, and further includes:

[0065] There are several support plates 21, each of which has a second protrusion 22. The support plate 21 is slidably arranged in the second slide groove 20 through the second protrusion 22. After the support plate 21 slides in the second slide groove 20, it is used to support or not support the side plate 18.

[0066] In this embodiment, the provision of the support plate 21 allows the side plate 18 to obtain additional support when needed, providing more diverse loading options to accommodate items of different weights or shapes. The design of the second slide 20 and the second protrusion 22 allows the support plate 21 to slide freely in the second slide 20, providing more adjustment points and increasing the flexibility of the baffle 3 system. The sliding support function of the support plate 21 can provide additional stability when loading heavier items and reduce the risk of bending or deformation of the side plate 18.

[0067] Optionally, also include:

[0068] There are a plurality of elastic members 23 , each of which has one end disposed on the bottom plate 16 and the other end disposed on a second protrusion 22 . The elastic member 23 is used to provide a force for the second protrusion 22 to approach the side plate 18 .

[0069] Optionally, also include:

[0070] The transmission member 24 is arranged on a plurality of support plates 21 .

[0071] In the embodiment, the setting of the elastic member 23 enables the second protrusion 22 to automatically approach the side plate 18 without manual operation, provides an automatic positioning mechanism, and simplifies the support process of the baffle 3. The force provided by the elastic member 23 ensures the close fit between the second protrusion 22 and the side plate 18, enhances the support stability of the baffle 3 system, and is suitable for carrying heavy or irregularly shaped items. The elastic action of the elastic member 23 reduces the manual force required when adjusting the position of the support plate 21, so that the user can more easily adjust the support plate 21 to adapt to the side plates 18 of different heights. The addition of the elastic member 23 improves the responsiveness of the entire baffle 3 system, so that the support plate 21 can quickly adapt to the change of the position of the side plate 18 and provide the required support force in time. The design of the elastic member 23 reduces the use of mechanical parts, thereby reducing the possibility of wear and failure, and improving the durability of the baffle 3 system. The transmission member 24 is set on the support plate 21, which may be used to adjust the position or fixed state of the support plate 21, thereby improving the efficiency and accuracy of the adjustment process.
