Description

Technical Field

[0001] This application relates to the field of transportation equipment technology, and in particular to a foldable material transportation tooling structure. Background Technology

[0002] When transporting materials, trolleys are usually needed. To prevent materials from falling during transport, most existing trolleys are equipped with vertical supports. However, these trolleys take up a lot of space when stored and cannot be stacked. Utility Model Content

[0003] This application provides a foldable material transport tooling structure to reduce the footprint of the transport vehicle when it is stored.

[0004] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0005] A foldable material transport fixture structure includes a base plate with casters installed below it. A vertical frame for preventing materials from falling is provided above the base plate. The vertical frame includes vertical rods and a top rod at the top of the vertical rods. The top rod connects multiple vertical rods. The end of the vertical frame away from the top rod is hinged to the base plate, and the vertical frame is connected to a support structure for limiting the rotation angle of the vertical frame.

[0006] By adopting the above solution, after the transport tooling structure is used up, the operator can rotate the vertical frame around the hinge axis to place the vertical frame flat on the base plate, thereby realizing the folding of the vertical frame and reducing the space occupied by the transport vehicle.

[0007] Optionally, the vertical rod includes an inner rod and an outer tube. The inner rod is inserted into the outer tube and slidably connected to the outer tube. The inner rod is fixedly connected to the top rod. The outer tubes located on both sides of the vertical frame are hinged to the base plate. The vertical rod is connected to a snap-fit ​​structure for fixing the inner rod and the outer tube.

[0008] By adopting the above solution, operators can adjust the height of the vertical frame by extending the inner rod out of the outer tube, enabling the transport tooling structure to transport larger materials.

[0009] Optionally, the snap-fit ​​structure includes a first bolt and a slider. Vertical holes are provided on the surface of the inner rods on both sides of the bracket, and grooves are provided in the vertical holes. The slider is slidably connected in the grooves, and threaded holes are provided on the surface of the slider. The first bolt is threadedly connected to the slider, and the first bolt passes through the outer tube and is rotatably connected to the outer tube.

[0010] By adopting the above solution, when it is necessary to fix the inner rod and the outer tube, the operator can rotate the first bolt to increase the portion of the first bolt screwed into the slider, thereby reducing the distance between the slider and the first bolt nut, thus clamping the inner rod and the outer tube, and thus fixing the inner rod and the outer tube.

[0011] Optionally, the top rod is a hollow pipe, and both ends of the top rod are slidably connected to extension rods, which can be inserted into the top rod.

[0012] By adopting the above solution and increasing the length of the top rod, the transport tooling structure can transport more materials.

[0013] Optionally, the support structure includes a support rod, which is a hollow tube. There are two support rods, which are respectively connected to the outer tubes located on both sides of the vertical frame. The connection between the support rod and the outer tube is located near the connection between the bend and the inner rod. The support rod is hinged to the outer tube, and the end of the support rod away from the outer tube abuts against the upper surface of the base plate.

[0014] By adopting the above scheme, when the vertical frame is erected, the end of the support rod away from the outer tube abuts against the surface of the base plate, thereby providing support for the vertical frame and restricting the vertical frame from rotating to the support rod side. Furthermore, the support rod is hinged to the outer tube, so when the vertical frame is stacked, the support rod can be stacked on top of the vertical frame, reducing the space occupied by the transport tooling structure.

[0015] Optionally, the support rod is a triangular support rod with one end hinged to the outer tube, which is used to increase the contact area between the outer tube and the support rod.

[0016] By adopting the above solution, the contact area between the support rod and the outer tube is increased, making the support rod's support for the outer tube more stable.

[0017] Optionally, the support rod is connected to a fixing structure for fixed connection with the base plate.

[0018] By adopting the above solution, the support rod is fixed to the base plate during transportation, thereby fixing the vertical frame and preventing it from rotating during use.

[0019] Optionally, the fixing structure includes a second bolt and a fixing post. A threaded hole is provided at one end of the support rod near the base plate. The second bolt is threaded into the threaded hole. The fixing post is fixedly connected to the base plate. A screw hole is provided on the surface of the fixing post. The fixing post is located at the position where the base plate abuts against the support rod. When the support rod abuts against the base plate, the fixing plate is located inside the support rod. Rotating the second bolt can cause the second bolt to be screwed into the screw hole of the fixing plate.

[0020] By adopting the above scheme, the second bolt fixes the support rod to the fixing plate, thereby fixing the support rod to the base plate, and then fixing the vertical frame to the base plate, making the vertical frame more stable during transportation. After use, the operator only needs to unscrew the second bolt from the fixing plate to separate the support rod from the base plate, so that the vertical frame and support plate can be folded, reducing the space occupied by the transportation tooling structure.

[0021] In summary, this application has the following technical effects:

[0022] 1. By setting the vertical frame to be hinged to the base plate and setting a support structure to support the vertical frame, the transport tooling structure can be folded, making the transport tooling structure occupy less space.

[0023] 2. By setting the first bolt and slider, the inner rod and outer tube can be fixed;

[0024] 3. By setting an extension rod to increase the length of the top rod, the transport tooling structure can transport more materials. Attached Figure Description

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1 and Figure 2 A foldable material transport fixture structure includes a base plate 1 with casters 2 mounted underneath. A vertical frame 3 is mounted above the base plate 1 to prevent materials from falling. The vertical frame 3 includes vertical rods 31 and a top rod 32 at the top of the vertical rods 31. The top rod 32 connects multiple vertical rods 31. The end of the vertical frame 3 facing away from the top rod 32 is hinged to the base plate 1, and a support structure is connected to the vertical frame 3 to limit its rotation angle. After use, the operator can rotate the vertical frame 3 around the hinge axis, allowing it to lie flat on the base plate 1, thus folding the vertical frame 3 and reducing the space occupied by the transport vehicle.

[0033] Reference Figure 3The vertical rod 31 includes an inner rod 311 and an outer tube 312. The inner rod 311 is inserted into the outer tube 312 and slidably connected to it. The inner rod 311 is fixedly connected to the top rod 32. The outer tubes 312 located on both sides of the vertical frame 3 are hinged to the base plate 1, and the vertical rod 31 is connected to a snap-fit ​​structure for fixing the inner rod 311 and the outer tube 312. The operator can adjust the height of the vertical frame 3 by extending the inner rod 311 out of the outer tube 312, so that the transport fixture structure can transport larger materials.

[0034] Reference Figure 3 and Figure 4 The snap-fit ​​structure includes a first bolt 41 and a slider 4. Vertical holes 3111 are formed on the surface of the inner rod 3111 located on both sides of the bracket, and grooves 3112 are formed within these holes. The slider 4 is slidably connected within the grooves 3112, and threaded holes are formed on its surface. The first bolt 41 is threadedly connected to the slider 4, and passes through the outer tube 312, rotatably connecting with it. When it is necessary to fix the inner rod 311 and the outer tube 312, the operator can rotate the first bolt 41 to increase the portion of the first bolt 41 screwed into the slider 4, thereby reducing the distance between the slider 4 and the nut of the first bolt 41, thus clamping the inner rod 311 and the outer tube 312, and thus fixing them.

[0035] Reference Figure 1 The top rod 32 is a hollow pipe, and both ends of the top rod 32 are slidably connected to extension rods 321, which can be inserted into the top rod 32. The extension rods 321 increase the length of the top rod 32, enabling the transport fixture structure to transport more materials.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The support structure includes support rods 5, which are hollow tubes. Two support rods 5 are provided, each connected to an outer tube 312 located on either side of the vertical frame 3. The connection point between the support rod 5 and the outer tube 312 is located near the connection point between the bend and the inner rod 311. The support rod 5 is hinged to the outer tube 312. One end of the support rod 5 is triangular, designed to increase the contact area between the outer tube 312 and the support rod 5, thus making the support more stable. The end of the support rod 5 facing away from the outer tube 312 abuts against the upper surface of the base plate 1. When the vertical frame 3 is erected, the end of the support rod 5 away from the outer tube 312 abuts against the upper surface of the base plate 1, thereby providing support for the vertical frame 3 and restricting the vertical frame 3 from rotating to the side of the support rod 5. The support rod 5 is hinged to the outer tube 312. When the vertical frame 3 is stacked, the support rod 5 can be stacked on top of the vertical frame 3, reducing the space occupied by the transport tooling structure.

[0037] Reference Figure 5The support rod 5 is connected to a fixing structure for fixed connection with the base plate 1. The fixing structure includes a second bolt 6 and a fixing post 61. A threaded hole is opened at the end of the support rod 5 near the base plate 1, and the second bolt 6 is threaded into the threaded hole. The fixing post 61 is fixedly connected to the base plate 1, and a threaded hole is opened on the surface of the fixing post 61. The fixing post 61 is positioned at the abutment position between the base plate 1 and the support rod 5. When the support rod 5 abuts against the base plate 1, the fixing plate is located inside the support rod 5. Rotating the second bolt 6 allows the second bolt 6 to be screwed into the threaded hole of the fixing plate. The second bolt 6 fixes the support rod 5 to the fixing plate, thereby fixing the support rod 5 to the base plate 1, and further fixing the vertical frame 3 to the base plate 1, making the vertical frame 3 more stable during transportation. After use, the operator only needs to unscrew the second bolt 6 from the fixing plate to separate the support rod 5 from the base plate 1, allowing the vertical frame 3 and the support plate to be folded, reducing the space occupied by the transportation tooling structure.

[0038] The specific implementation principle of this application is as follows: When the transport tooling structure is required, the vertical frame 3 is rotated around the hinge axis to make the vertical frame 3 stand up, and the support rod 5 abuts against the upper surface of the base plate 1. Then, the second bolt 6 is rotated so that the second bolt 6 is screwed into the screw hole of the fixing column 61, so that the fixing column 61 is fixed to the support frame. Then, the operator can adjust the height of the vertical frame 3 by adjusting the length of the inner rod 311 extending out of the outer tube 312, and by rotating the first bolt 41, the slider 4 and the first bolt 41 clamp the inner rod 311 and the outer tube 312, thereby fixing the inner rod 311 and the outer tube 312. Then, the material can be placed on the base plate 1. After use, simply unscrew the second bolt 6 and fold the vertical frame 3 and the support rod 5 to reduce the space occupied by the transport tooling structure.
