Technical Field
[0001] This utility model relates to the technical field of semi-trailer accessories, and in particular to a support frame for a semi-trailer toolbox. Background Technology
[0002] As an important road transport tool, semi-trailers typically require toolboxes to store repair equipment and other items. Due to the complex road conditions and continuous vibrations encountered during long-distance travel, the stability and vibration damping performance of the toolboxes are crucial. Traditional semi-trailer toolbox fixing structures lack effective vibration damping mechanisms. When subjected to road vibrations and impacts during vehicle operation, the toolbox body is prone to excessive vibration, affecting its structural strength and service life. Existing toolbox installation methods mostly use rigid connections, which are complex to install and remove, hindering daily maintenance and quick toolbox replacement, and failing to meet the convenience requirements of modern transport equipment. Therefore, a semi-trailer toolbox support frame needs to be designed to solve these problems. Utility Model Content

A docking assembly is sleeved on the right end of the multiple through rods on the upper side and the right end of the multiple through rods on the lower side, and the docking assemblies are symmetrically distributed vertically.
[0007] Preferably, the docking assembly includes a right side plate, and the right side wall of the right side plate is provided with a plurality of through holes. The through rod can be inserted into the through holes from the left side plate to realize the docking of the left side plate and the right side plate. A buffer block II is fixedly connected to the rear end of the right side plate, and a buffer spring II is fixedly connected to the upper and lower ends of the buffer block II.
[0008] Preferably, the number of insertion holes is the same as the number of insertion rods, and the position of the insertion hole corresponds one-to-one with the position of the corresponding insertion rod.

[0019] Please see Figure 1-5 This utility model provides a technical solution: A toolbox support frame for a semi-trailer, such as Figure 1-5 As shown, the toolbox includes a toolbox body 1, a fixing device 3 is sleeved on the outside of the toolbox body 1, and an installation device 2 is movably connected to the outside of the fixing device 3. There are two installation devices 2, and the two installation devices 2 are symmetrically distributed on the left and right.
[0020] Please see Figure 2 , Figure 3 and Figure 4The mounting device 2 includes a herringbone mounting bracket 21. Two buffer grooves 22 are provided on both sides of the herringbone mounting bracket 21, and four mounting holes 23 are provided at the rear end of the herringbone mounting bracket 21.
[0021] With the above scheme: the mounting device 2 fixes the entire support frame to the semi-trailer through the herringbone mounting bracket 21 and the mounting hole 23 at its rear end. At the same time, the buffer grooves 22 on its two outriggers respectively accommodate the buffer block 33 on the left side of the fixing device 3 and the buffer block 384 at the rear end of the right side plate 381. The buffer spring 34 set at the upper and lower ends of the buffer block 33 and the buffer spring 383 fixed at the upper and lower ends of the buffer block 384 together constitute the core shock absorption and buffer mechanism.
[0022] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The fixing device 3 includes a left side plate 31, of which two are provided. Multiple through rods 32 are fixedly connected to the right side wall of each left side plate 31. A buffer block 33 is fixedly connected to the rear end of each left side plate 31. A buffer spring 34 is provided at both the upper and lower ends of the buffer block 33. A connecting plate 35 is fixedly connected to the upper and lower ends of the multiple through rods 32 on the upper and lower sides. Mounting rods 36 are fixedly connected to the four corners of the upper end of the lower connecting plate 35. Locking sleeves 37 are threaded onto the upper part of the outer surface of each mounting rod 36. A docking assembly 38 is sleeved on the right end of both the multiple through rods 32 on the upper and lower sides, and the docking assemblies 38 are symmetrically distributed vertically. The docking assembly 38 includes a right side plate 381. Multiple through holes 382 are provided on the right side wall. Through rods 32 can be inserted into the through holes 382 from the left side plate 31 to connect the left side plate 31 and the right side plate 381. A buffer block 384 is fixedly connected to the rear end of the right side plate 381. A buffer spring 383 is fixedly connected to the upper and lower ends of the buffer block 384. The number of through holes 382 is the same as the number of through rods 32, and the position of the through holes 382 corresponds one-to-one with the position of the corresponding through rod 32. The outer contour shape of the buffer block 384 is adapted to the inner contour shape of the buffer groove 22. The buffer blocks 384 on the right side are located in the buffer groove 22 on the right side. The toolbox body 1 is placed between the upper and lower rows of through rods 32. The buffer blocks 33 on the left side are located in the buffer groove 22 on the left side.
[0023] Through the above scheme: the multiple through rods 32 fixedly connected to the right side walls of the two left side plates 31 in the fixing device 3 correspond one-to-one with the number and position of the through holes 382 of the right side plate 381 in the docking assembly 38 to achieve docking, which can stably clamp the toolbox body 1 between the upper and lower rows of through rods 32. The connecting plates 35 connected to the upper and lower through rods 32 respectively enhance the structural strength of the through rods 32. The mounting rod 36 on the lower connecting plate 35 cooperates with the locking sleeve block 37 to further strengthen the fixation of the toolbox body 1. The buffer block 33 at the rear end of the left side plate 31 and the buffer spring 34 at the upper and lower ends, and the buffer block 384 at the rear end of the right side plate 381 and the buffer spring 383 at the upper and lower ends are respectively embedded in the buffer groove 22 of the mounting device 2 to form a multi-buffered structure, which can effectively absorb the vibration and impact force when the semi-trailer is traveling, and prevent the toolbox body 1 from being damaged by bumps. At the same time, through the combined installation of the fixing device 3 and the mounting device 2, the toolbox body 1 can be conveniently installed on the semi-trailer.
[0024] It should be noted that this utility model is a toolbox support frame for a semi-trailer. The toolbox body 1 is placed between two rows of through rods 32 and clamped and fixed by the left side plate 31 and the right side plate 381 in the fixing device 3. The through rods 32 on the left side plate 31 are inserted into the corresponding through holes 382 on the right side plate 381 to achieve docking. The toolbox body 1 is locked and fixed by the connecting plate 35 and the mounting rod 36 in conjunction with the locking sleeve 37. At the same time, the herringbone mounting bracket 21 in the mounting device 2 is installed on the semi-trailer through the mounting holes 23. The buffer grooves 22 on both sides of the bracket respectively accommodate the first buffer block 33 on the left side of the fixing device 3 and the second buffer block 384 on the right side. The first buffer spring 34 on the first buffer block 33 and the second buffer spring 383 on the second buffer block 384 provide shock absorption and cushioning when the vehicle is moving, thereby stabilizing and protecting the toolbox body 1.
