Description

Technical Field

[0001] This invention relates to the field of transport vehicle technology, and more particularly to an adjustable connection structure for a tool vehicle. Background Technology

[0002] There are many parts in the machining workshop, some small and some large, which are very inconvenient to move. In order to improve the efficiency of parts transportation, the factory often uses small carts as tool carts to transport parts over short distances, and sometimes it is also necessary to transport the tools used.

[0003] Traditional trolleys are basically composed of a cargo bed, handles, and rollers at the bottom of the cargo bed. By gripping the handles, the front of the trolley can be moved to transport parts or tools. Although current trolleys have undergone structural improvements to address various usage issues, their transport capacity is still limited. Even with structural improvements, the transport capacity of these trolleys remains small. Moreover, the specifications and models of these trolleys are fixed, and their transport capacity cannot be adjusted according to the number of parts. Once the number of parts exceeds the transport capacity of a standard trolley, a truck or crane is needed to haul the goods. However, in many cases, even if the number of parts far exceeds the transport capacity of the trolley, it is still insufficient to meet the carrying capacity of a truck or crane, resulting in a waste of human and material resources.

[0004] Therefore, it is necessary to propose an adjustable connection structure for the tool cart, which can flexibly adjust the transport capacity of the cart to avoid the waste of human and material resources and improve the transport efficiency of the cart. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the transport capacity of existing trolleys cannot be adjusted according to the number of parts, resulting in a waste of human and material resources. An adjustable connection structure for tool carts is provided.

[0006] The technical solution of this invention is:

[0007] An adjustable tool cart connection structure includes a support frame, a walking platform at one end of the support frame, the walking platform being an inclined plane, connecting rods on both sides of the walking platform, the connecting rods being rotatably connected to the side wall of the support frame, a handle being fixedly connected to the top of the connecting rods, a storage slot and a track slot being provided on the top of the support frame, the track slots being arranged parallel to both sides of the storage slot, and rollers being installed at the bottom of the support frame, the width of the track slots matching the width of the rollers;

[0008] The side wall of the track groove has a notch for accommodating the handle. The connecting rod can rotate relative to the support frame, so that the handle overlaps on the top of the support frame. The handle can enter the notch, thereby dividing the track groove into two parts.

[0009] Furthermore, an arc-shaped groove is provided on the side wall of the grip, and when the grip is located in the notch, the opening of the arc-shaped groove faces the top of the support frame.

[0010] Furthermore, the arc-shaped groove is an inwardly concave arc-shaped groove.

[0011] Furthermore, there are two sets of rollers, with two rollers forming a set. The rollers are located at the bottom of the support frame, and a set of rollers is installed at each end of the support frame.

[0012] Furthermore, the connecting rod, the traveling platform, and a set of rollers are all located at the same end of the support frame, and the set of rollers are omnidirectional wheels.

[0013] Furthermore, the end of the support frame on which the walking platform is installed is the walking end, and the end of the support frame opposite to the walking end is the connecting end;

[0014] The connecting end is equipped with a connecting platform, which is an inclined plane, and the inclination angle is complementary to the inclination angle of the walking platform.

[0015] Furthermore, a fixed base extending towards the bottom of the walking platform is fixedly connected to the top of the walking platform, and a fixing hole matching the fixed base is provided at the corresponding position of the walking platform.

[0016] Furthermore, the two support frames can be inserted into the fixing holes for front-to-back docking.

[0017] Furthermore, one support frame can roll onto the track groove on another support frame via its own rollers, thus allowing the two support frames to be stacked together.

[0018] This invention discloses an adjustable tool cart connection structure. Storage slots are provided on the support frame for holding parts, while side rails are for placing rollers on another support frame. The rails allow for the stacking of two support frames. When the storage slot on one support frame is full, a second support frame can be added on top, increasing the overall transport capacity. Furthermore, the system allows for flexible selection of whether to stack two or three support frames depending on the number of parts. Compared to traditional technologies, this solution solves the problem of limited cart transport capacity. Tool carts with this connection structure can be freely assembled and stacked, adjusting the cart's transport capacity. The number of carts to be stacked can be more appropriately selected based on the actual number of parts to achieve high-efficiency transport, minimizing waste of human and material resources and improving cart transport efficiency.

[0029] To make the technical means, technical features, inventive purpose and technical effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0030] Example 1:

[0031] like Figure 1 and Figure 2 As shown, an adjustable tool cart connection structure includes a support frame 1, a walking platform 2 at one end of the support frame 1, the walking platform 2 being an inclined plane, and connecting rods 3 on both sides of the walking platform 2. The connecting rods 3 are rotatably connected to the side walls of the support frame 1 via pins, and a handle 4 is welded to the top of the connecting rod 3. Figure 3 and Figure 4 As shown, the top of the support frame 1 is provided with a storage slot 5 and a track slot 6. The track slot 6 is arranged parallel to both sides of the storage slot 5. The bottom of the support frame 1 is equipped with a roller 7. The width of the track slot 6 matches the width of the roller 7.

[0032] The side wall of the track groove 6 is provided with a notch 8 to accommodate the handle 4. The connecting rod 3 can rotate relative to the support frame 1 so that the handle 4 overlaps on the top of the support frame 1. The handle 4 can enter the notch 8, thereby dividing the track groove 6 into two parts. Preferably, the notch 8 is rectangular.

[0033] like Figure 5 As shown, preferably, an arc-shaped groove 9 is provided on the side wall of the grip 4, and when the grip 4 is located in the notch 8, the opening of the arc-shaped groove 9 faces the top of the support frame 1.

[0034] Preferably, the arc-shaped groove 9 is an inwardly concave arc-shaped groove 9.

[0035] like Figure 6 and Figure 9 As shown, the arc-shaped groove 9 is designed such that when the handle 4 is folded into the notch 8, the arc-shaped groove 9 faces upwards. When the handle 4 is not folded into the notch 8, when the worker pulls the handle 4, the gripping surface of the palm is the circular sidewall of the handle 4, while the fingers can be located within the arc-shaped groove 9. This increases the worker's grip comfort, allowing the worker's hand to exert force and preventing slippage. On the other hand, when the handle 4 is folded into the notch 8, with the rotation of the connecting rod 3, the arc-shaped groove 9 faces upwards, and when there is another support frame 1 with roller 7... When the roller 7 rolls into the track groove 6, it can be positioned exactly within the arc-shaped groove 9. Since the arc-shaped groove 9 is a concave arc-shaped groove, the roller 7 can be positioned within it to limit the movement of the support frame 1 above, thus restricting the forward and backward movement of the roller 7. The track groove 6 itself can also restrict the left and right directions. Therefore, the roller 7, i.e. the universal wheel of the traveling end 11, cannot rotate or move in the forward, backward, left, or right directions, thus achieving a limiting and fixing effect, making it more convenient for workers to push the trolley for transportation.

[0036] Preferably, there are two sets of rollers 7, with each set consisting of two rollers 7. The rollers 7 are located at the bottom of the support frame 1, and a set of rollers 7 is installed at each end of the support frame 1. This means that four rollers 7 are installed around the bottom of each support frame 1.

[0037] Preferably, the connecting rod 3, the traveling platform 2 and a set of rollers 7 are all located at the same end of the support frame 1, and the set of rollers 7 are omnidirectional wheels, which can ensure steering.

[0038] Preferably, the end of the support frame 1 on which the walking platform 2 is installed is the walking end 11, and the end of the support frame 1 opposite to the walking end 11 is the connecting end 12. The connecting end 12 is provided with a connecting platform 10, which is an inclined plane and the inclination angle is complementary to the inclination angle of the walking platform 2. This ensures that when the two support frames 1 are spliced ​​together, they can be joined together front and back. Preferably, the vertical cross-section of the support frame 1 is a parallelogram.

[0039] Preferably, a fixed seat 13 extending vertically downwards is welded to the top of the walking platform 2. A fixing hole 14 matching the fixed seat 13 is provided at the corresponding position of the walking platform 2. Preferably, the cross-section of the fixed seat 13 and the fixing hole 14 are both circular, and there are at least two fixed seats 13 and fixing holes 14. The two support frames 1 can insert the fixed seat 13 into the fixing hole 14 for front-to-back docking. After insertion, since the connecting platform 10 and the walking platform 2 are inclined planes with complementary angles, seamless docking can be achieved, so that the two support frames 1 can be assembled and connected together horizontally to form a whole, thereby increasing the transport capacity.

[0040] like Figure 7 and Figure 8 As shown, preferably, one support frame 1 can roll its own roller 7 into the track groove 6 on another support frame 1 to achieve the stacking of the two support frames 1. Specifically, the first support frame 1 is pushed through the walking platform 2 of the second support frame 1. The walking platform 2 is connected to the track groove 6, and the roller 7 enters the track groove 6 to realize the assembly of the two support frames 1 in the vertical direction, thereby increasing the transport capacity.

[0041] During operation, to ensure that the rollers 7 of the stacked upper support frame 1 are properly positioned and fixed by the arc-shaped groove 9, the optimal method is to require at least three support frames 1 if a two-layer tool cart needs to be assembled. The bottom two support frames 1 are horizontally joined together and fixed using the fixing seat 13 and fixing hole 14. The upper second-layer support frame 1 is located on the right side of the first-layer support frame 1. Because the handle 4 of the right side support frame 1 of the first layer overlaps within the notch 8, the second-layer support frame 1 stacked on this support frame 1 can be fixed and fixed by the arc-shaped groove 9. The first layer's left-side support frame 1 is used to prevent the trolley from swaying or shifting during transport. The handle 4 is fixed externally for workers to manually push and pull. In short, regardless of the number of layers required for the tool cart, it's best to leave a support frame 1 at the end of the first layer, without stacking new support frames 1 on top. This allows the handle 4 on this support frame 1 to be used by workers for traction. Of course, stacking new support frames 1 on top is possible, but without the limiting effect of the arc-shaped groove 9, the rollers 7 located in this track groove 6 may shift. If unstable and unreliable, workers need to hold onto this support frame 1 to prevent swaying and shifting.

[0042] A storage slot 5 is provided on the support frame 1 to hold parts, while the track slots 6 on both sides are used to place the rollers 7 of another support frame 1. The track slots 6 enable the stacking of two support frames 1. When the storage slot 5 of one support frame 1 is full, a second support frame 1 can be stacked on top, thereby increasing the upper limit of the trolley's transport capacity. Furthermore, it allows for flexible selection of whether to stack two or three support frames 1 together, depending on the number of parts. Compared with traditional technologies, this technical solution solves the problem of limited trolley transport capacity. Moreover, the tool carts under this connection structure can be freely assembled and stacked to adjust the trolley's transport capacity. The number of trolleys to be stacked can be more appropriately selected according to the actual number of parts to achieve high-efficiency transportation, minimize the waste of human and material resources, and improve the trolley's transport efficiency.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes and modifications made in accordance with the scope of the claims of this invention should fall within the technical scope of this invention.
