Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of flatbed transport vehicles, and specifically relates to a protective structure for a flatbed transport vehicle. Background Technology
[0002] Flatbed trucks are used for carrying, moving, transporting, and loading / unloading goods. They use a flatbed body to carry goods, controlled by wheels located underneath. Goods are placed directly on the flatbed, which is open on all sides. This openness makes it easy for large items to protrude outwards. While the wheels are fixed in designated positions under the flatbed, this outward protrusion can cause the flatbed to shift and lift during transport, failing to effectively prevent goods from obstructing the flatbed or protecting the truck from pressure and shifting, thus affecting its usability. Utility Model Content
[0003] This utility model provides a protective structure for a flatbed transport vehicle, which improves the performance and safety of the flatbed transport vehicle.
[0004] This utility model provides the following technical solution: It includes a cargo flatbed, under which are six wheels symmetrically distributed in pairs. Below the cargo flatbed are six corresponding connecting and adjusting assemblies for the wheels. Each connecting and adjusting assembly includes an L-shaped connecting plate, side blocks, and fixing screws. The wheels are rotatably connected to the bottom of the L-shaped connecting plate. The side blocks are horizontally movable on the outside of the cargo flatbed via the L-shaped connecting plate and are fixed by the fixing screws. A blocking and protective assembly is provided on the outside of the L-shaped connecting plate. The blocking and protective assembly includes a stop bar and a connecting column. The stop bar rotates on the outside of the cargo flatbed via the connecting column.
[0005] The L-shaped connecting plate is fixedly connected to a T-shaped guide block at its top, and the cargo flat plate has several T-shaped guide grooves corresponding to the T-shaped guide blocks at its bottom. The T-shaped guide blocks are slidably connected inside the corresponding T-shaped guide grooves.
[0006] Among them, the two connecting adjustment components in symmetrical positions are staggered, and three positioning blocks are fixedly connected to the bottom of the cargo flat plate. The positioning blocks are engaged with the inner sides of the corresponding two L-shaped connecting plates.
[0007] The side block is fixedly connected to the wide end of the L-shaped connecting plate, and the side block engages with the corresponding side of the cargo flatbed.
[0008] The fixing screw is screwed inside the side stop block, and the front end of the fixing screw is screwed and fixed inside the cargo flatbed.
[0009] The connecting column is fixedly connected to the width of the L-shaped connecting plate, and the bottom end of the stop bar is rotatably connected to the other end of the connecting column.
[0010] The stop bar has an inner rod inserted inside it, and the top end of the inner rod extends to the outside of the stop bar.
[0011] The beneficial effects of this utility model are:
[0012] This invention features six staggered connecting and adjusting components, connecting six wheels to the bottom of the cargo platform. The wheels are rotatably connected to corresponding L-shaped connecting plates, ensuring free movement of the wheels beneath the platform. The L-shaped connecting plates, carrying the wheels, can move horizontally outwards beneath the platform. By operating the fixing screws, the positions of the L-shaped connecting plates and wheels after outward movement can be fixed, facilitating adjustments and fixation of their positions under the platform. This effectively increases the platform's coverage area based on the cargo, stably and effectively supporting goods of different sizes. A blocking and protective component located at the wide end of the L-shaped connecting plate is always positioned on the outside of the platform. The blocking bar can rotate on the outside of the platform via connecting columns, allowing adjustment of its position to block and protect cargo at different locations. This effectively blocks and protects cargo from pressure and displacement on the platform, improving the safety of the flatbed truck.

[0019] Example:
[0020] Please see Figures 1-4 The present invention provides the following technical solution: a cargo flatbed 1, with six wheels 2 symmetrically distributed in pairs below the cargo flatbed 1, and a connecting adjustment assembly 3 corresponding to the six wheels 2 below the cargo flatbed 1. The connecting adjustment assembly 3 includes an L-shaped connecting plate 31, a side block 32, and a fixing screw 33. The wheels 2 are rotatably connected to the bottom of the L-shaped connecting plate 31. The side block 32 moves horizontally to the outside of the cargo flatbed 1 through the L-shaped connecting plate 31 and is fixed by the fixing screw 33. A blocking and protective assembly 4 is provided on the outside of the L-shaped connecting plate 31. The blocking and protective assembly 4 includes a stop bar 41 and a connecting post 42. The stop bar 41 rotates to the outside of the cargo flatbed 1 through the connecting post 42.
[0021] In this implementation plan: six wheels 2 are symmetrically distributed in pairs below the cargo flatbed 1, and six connecting adjustment components 3 are provided below the cargo flatbed 1. The six connecting adjustment components 3 correspond to the six wheels 2, and the six connecting adjustment components 3 are connected to the six wheels 2 respectively, so that the cargo flatbed 1, the six wheels 2 and the six connecting adjustment components 3 cooperate to form a flatbed transport vehicle.
[0022] The connecting adjustment assembly 3 consists of an L-shaped connecting plate 31, a side stop block 32, and a fixing screw 33. A T-shaped guide block 311 is fixedly connected to the top of the L-shaped connecting plate 31. Several T-shaped guide grooves 12 corresponding to the T-shaped guide blocks 311 are opened at the bottom of the cargo flatbed 1. The T-shaped guide blocks 311 are slidably connected inside the corresponding T-shaped guide grooves 12. The T-shaped guide blocks 311 move outward along the groove wall of the corresponding T-shaped guide groove 12 inside the corresponding T-shaped guide groove 12, allowing the L-shaped connecting plate 31 to move horizontally outward against the bottom of the cargo flatbed 1. The wheels 2 are rotatably connected to the bottom of the L-shaped connecting plate 31 to facilitate horizontal outward adjustment of the positions of the L-shaped connecting plate 31 and the wheels 2. The two connecting adjustment assemblies 3 in symmetrical positions are staggered. Three positioning blocks 11 are fixedly connected to the bottom of the cargo flatbed 1. The positioning block 11 is engaged with the inner side of the corresponding two L-shaped connecting plates 31. It serves to block the corresponding L-shaped connecting plate 31 at the bottom of the cargo flatbed 1 to prevent the L-shaped connecting plate 31 from continuing to move at the bottom of the cargo flatbed 1 after it has reset inward. The side block 32 is fixedly connected to the wide end of the L-shaped connecting plate 31. The side block 32 engages with the corresponding side of the cargo flatbed 1. After the L-shaped connecting plate 31 resets to the bottom of the cargo flatbed 1, it further blocks and positions the L-shaped connecting plate 31 at the bottom of the cargo flatbed 1. The fixing screw 33 is screwed into the inside of the side block 32. The front end of the fixing screw 33 is screwed and fixed inside the cargo flatbed 1, which can fix the position of the side block 32, thereby fixing the position of the L-shaped connecting plate 31, so as to facilitate the position adjustment and fixing of the L-shaped connecting plate 31 and the corresponding wheel 2.
[0023] The blocking and protective assembly 4 is located on the outside of the L-shaped connecting plate 31. The blocking and protective assembly 4 consists of a stop bar 41 and a connecting post 42. The connecting post 42 is fixedly connected to the width of the L-shaped connecting plate 31. The bottom end of the stop bar 41 is rotatably connected to the other end of the connecting post 42, so that the stop bar 41 is stably rotatably connected to the outside of the cargo platform 1 through the connecting post 42, so as to facilitate the adjustment of the position of the stop bar 41 on the outside of the cargo platform 1. An inner rod 43 is inserted inside the stop bar 41. The top end of the inner rod 43 extends to the outside of the stop bar 41, so as to facilitate the adjustment of the position of the inner rod 43 inside the stop bar 41, thereby changing the overall length of the stop bar 41 and the inner rod 43. The inner rod 43 can rotate with the stop bar 41 on the outside of the cargo platform 1 to effectively block and protect different areas of the cargo and improve the protection range.
[0024] Six staggered connecting adjustment components 3 are connected to six wheels 2 at the bottom of the cargo platform 1, forming a complete flatbed transport vehicle. The wheels 2 are rotatably connected to the bottom of the corresponding L-shaped connecting plates 31 to ensure the free movement of the wheels 2 under the cargo platform 1. Goods are placed on top of the cargo platform 1, and the wheels 2 move on the ground to move the cargo platform 1 and the goods together to complete the transport operation. The L-shaped connecting plates 31 can move horizontally outward under the cargo platform 1 along with the wheels 2. After adjusting the position of the wheels 2 outward, and adjusting the wheels 2, L-shaped connecting plates 31, and corresponding blocking and protective components 4 to the position of the corresponding edge of the goods, the position of the L-shaped connecting plates 31 and wheels 2 after moving outward can be fixed by operating the fixing screws 33. This facilitates the adjustment and fixing of the position of the L-shaped connecting plates 31 and wheels 2 under the cargo platform 1, and can effectively increase the coverage area of the cargo platform 1 according to the situation of the goods, so as to stably and effectively carry goods of different sizes. The blocking and protection component 4, which is set at the wide end of the L-shaped connecting plate 31, is always located on the outside of the loading plate 1 and the goods. The stop bar 41 can rotate on the outside of the loading plate 1 through the connecting column 42, so as to adjust the position of the stop bar 41 to block and protect the goods at different positions. It can effectively block and protect the goods on the loading plate 1 and protect the loading plate 1 from pressure and displacement, thereby improving the safety of using the flatbed truck.
