Technical Field

[0001] The utility model relates to the technical field of semi-trailer boxes, and specifically relates to an anti-collision frame for a semi-trailer box. Background Technique

[0002] The semi-trailer has its axles placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded), and is equipped with a coupling device that can transfer horizontal and vertical forces to the tractor. The semi-trailer is generally a three-axle semi-trailer, and its types include eleven-meter barn semi-trailers, thirteen-meter barns, low-bed semi-trailers, and many other types. It is a heavy-duty transportation vehicle connected to the semi-trailer head through a kingpin.

[0003] The semi-trailer carriage is usually used for long-distance large-volume cargo transportation. Most carriages will choose to carry goods on the return journey to earn freight and reduce the cost of the vehicle's return journey. In most cases, the truck will return fully loaded, but in some cases, the vehicle cannot find fully loaded goods in time for the return journey and will also choose to return half-empty. During the loading process, if all the goods are laid flat on the bottom of the carriage, it will cause the center of gravity to move backward, affecting the driving stability. And if all are stacked near the front side, it is easy to cause the collapse of the goods, affecting the integrity of the goods during transportation. For this reason, we propose an anti-collision frame for a semi-trailer box. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an anti-collision frame for a semi-trailer box, which solves the problems raised in the above background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: An anti-collision frame for a semi-trailer box includes a carriage. At positions near the left and right sides inside the carriage, a limiting frame is fixedly installed. At the position on the left side inside the carriage, a movable frame is movably sleeved. A sliding groove is opened inside the movable frame, and a movable block is movably sleeved inside the sliding groove. An anti-collision rod is installed between the two movable blocks. A rotating shaft is movably supported inside the anti-collision rod, a support rod is fixedly connected to the outer side of the rotating shaft, and a support frame is movably sleeved inside the anti-collision rod.

[0006] Optionally, a positioning rod is movably sleeved on the upper surface of the movable frame, and the positioning rod extends upward above the carriage.

[0007] Optionally, the bottom of the movable frame is mutually attached to the outer side of the limiting frame, and the limiting frame extends backward outside the carriage.

[0008] Optionally, the rotating shaft is located inside the anti-collision rod, and when the support rod is in the inner cavity state of the anti-collision rod, the top surface of the support rod and the top surface of the anti-collision rod are on the same horizontal plane.

[0009] Optionally, the vertical cross-section of the support rod is L-shaped, the horizontal cross-section of the movable block is L-shaped, and the length value of the anti-collision rod is the same as the spacing value of the two movable frames.

[0010] The utility model provides an anti-collision frame for a semi-trailer box, which has the following beneficial effects:

[0011] 1. For the anti-collision frame for the semi-trailer box, through the setting of the carriage, a limiting frame is arranged near the left and right sides inside the carriage, which can limit the movement range of the movable frame. The anti-collision rod arranged between the two movable frames can prevent the collapse of the goods, and the goods can be stacked near the front side, while ensuring the stability of the goods and the safety during transportation.

[0012] 2. For the anti-collision frame for the semi-trailer box, through the provision of a sliding groove between the two movable frames, the movable block inside the sliding groove can movably support the anti-collision rod, so that the anti-collision rod can move up and down. The cooperation of multiple anti-collision rods can comprehensively limit the position of the goods. At the same time, the inner cavity of the anti-collision rod supports the support rod through a rotating shaft and can move within a range of 90 degrees, so as to complete the support of the upper anti-collision rod and the support of the positions of multiple anti-collision rods.

[0019] Please refer to Figures 1 to 4, the present utility model provides a technical solution: an anti-collision frame for a semi-trailer box, which includes a carriage 1. Limit frames 2 are fixedly installed at positions near the left and right sides inside the carriage 1. The bottom of the movable frame 3 is in mutual contact with the outer side of the limit frame 2. The limit frame 2 extends backward to the outside of the carriage 1. The setting of the limit frame 2 plays a role in restricting the movement range of the movable frame 3, preventing the movable frame 3 from moving to the outside of the carriage 1. At the same time, the rear end of the limit frame 2 can limit the position of the movable frame 3, facilitating the use of the device and improving the practicality of the device. A movable frame 3 is movably sleeved at a position on the left side inside the carriage 1. A positioning rod 10 is movably sleeved on the upper surface of the movable frame 3. The positioning rod 10 extends upward above the carriage 1. The setting of the positioning rod 10 plays a positioning role, can stably fix the position of the movable frame 3, prevent the movable frame 3 from moving during transportation, affect the stability of transporting the movable frame 3, and further affect the stability of the goods, facilitating the use of the device and improving the practicality of the device. A chute 9 is provided inside the inner side of the movable frame 3. A movable block 4 is movably sleeved inside the chute 9. The vertical cross-section of the support rod 7 is L-shaped, and the horizontal cross-section of the movable block 4 is L-shaped. The length value of the anti-collision rod 5 is the same as the spacing value between the two movable frames 3. The opening of the chute 9 enables the movable block 4 to slide up and down inside the chute 9, and then enables the anti-collision rod 5 to move up and down. The cooperation of multiple anti-collision rods 5 can be used to complete the stable limiting of the goods, preventing the goods from collapsing and affecting the stability of the goods. An anti-collision rod 5 is installed between the two movable blocks 4. A rotating shaft 6 is located inside the anti-collision rod 5. When the support rod 7 is in the inner cavity state of the anti-collision rod 5, the top surface of the support rod 7 and the top surface of the anti-collision rod 5 are on the same horizontal plane. Pull up the upper anti-collision rod 5, and then rotate the support rod 7 and the rotating shaft 6 inside the lower anti-collision rod 5, and use the rotating shaft 6 to support the upper anti-collision rod 5. Then, place a support frame 8 inside the anti-collision rod 5 to support the rotating shaft 6 and the support rod 7. The rotating shaft 6 is movably supported inside the anti-collision rod 5. The outer side of the rotating shaft 6 is fixedly connected to the support rod 7. A support frame 8 is movably sleeved inside the anti-collision rod 5. The setting of the support frame 8 plays a limiting role, can limit the positions of the rotating shaft 6 and the support rod 7, facilitating the use of the device and improving the stability and practicality of the device.

[0020] In summary, for the anti-collision frame for the semi-trailer box, during use, first, the support frames 8 inside all the anti-collision bars 5 are taken out. Subsequently, the rotating shaft 6 and the support rod 7 are rotated so that the support rod 7 is located inside the anti-collision bar 5. Then, all the anti-collision bars 5 are stacked. Then, the goods are placed inside the carriage, and the goods are placed at a position near the front side inside the carriage. After stacking is completed, the movable frame 3 is moved to a position close to the rear of the goods, and the positions of the movable frame 3 and the carriage 1 are restricted by the positioning rod 10 to prevent the movement of the movable frame 3. Then, the upper anti-collision bar 5 is pulled upward. Subsequently, the support rod 7 and the rotating shaft 6 inside the lower anti-collision bar 5 are rotated, and the rotating shaft 6 is used to support the upper anti-collision bar 5. Then, the support frame 8 is placed inside the anti-collision bar 5 to support the rotating shaft 6 and the support rod 7 to prevent the collapse of the rotating shaft 6 and the support rod 7. With the cooperation of the movable frame 3 and the anti-collision bar 5, the stable restriction during the transportation of the goods can be completed, and that's it.
