All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.
[0030] Embodiment 1:
[0031] Please refer to Figures 1-4 As shown, the present utility model is an anti-impact mechanism for the cargo compartment of a freight truck, including two pairs of guide rails 1 horizontally bolted to the opposite side walls of the freight truck cargo compartment respectively; a pair of positioning frames 2 are arranged vertically side by side between the two pairs of guide rails 1; a pair of support blocks 3 are rotatably connected side by side to one side edge of the two positioning frames 2; a slider 4 is welded to each of the two pairs of support blocks 3; the two pairs of sliders 4 are respectively slidably connected to the two pairs of guide rails 1; the other side edges of the two positioning frames 2 are connected by a pair of connecting members 5, and a plurality of limiting rods 6 are vertically connected side by side between the upper and lower side edges of each positioning frame 2. When in use, when loading the freight truck cargo compartment, separate the two positioning frames 2 and make the two positioning frames 2 respectively adhere to the opposite side walls of the cargo compartment, which can facilitate loading the goods into the cargo compartment. Then, after the loading is completed, adjust the position of the positioning frame 2 through the slider 4, and then connect the two positioning frames 2 by using the connecting member 5 to make the two positioning frames 2 parallel to the front side wall of the cargo compartment. Then, move the slider 4 to make the limiting rod 6 contact with the goods in the cargo compartment, so as to position the goods between the front side wall of the cargo compartment and the positioning frame 2, thereby effectively avoiding problems such as the goods sliding back and forth in the cargo compartment or impacting the compartment wall of the cargo compartment when the freight truck starts quickly or brakes suddenly. At the same time, it also reduces the damage rate of the goods and extends the service life of the freight truck cargo compartment.
[0032] Embodiment 2:
[0033] On the basis of Embodiment 1, as Figures 4-5As shown in the figure, a mounting cylinder 401 is perpendicularly welded to one side surface of the slider 4 away from the guide rail 1; a first stud 402 is in threaded fit with the mounting cylinder 401; one end of the first stud 402 slidably penetrates through the slider 4 and abuts against one side surface of the guide rail 1 close to the positioning frame 2; a plurality of accommodating holes 101 corresponding to the first stud 402 are arranged side by side along the length direction on one side surface of the guide rail 1 close to the positioning frame 2; one end of the first stud 402 is slidably inserted into any one of the accommodating holes 101. During use, when the limiting rod 6 abuts against the goods in the cargo compartment, by sliding one end of the first stud 402 through the slider 4 and tightly abutting it against one side surface of the guide rail 1 close to the positioning frame 2 or sliding one end of the first stud 402 into an adjacent accommodating hole 101, the position of the slider 4 can be locked, effectively preventing the slider 4 from sliding randomly on the guide rail 1, thereby effectively improving the use effect of the positioning frame 2.
[0034] Among them, as Figure 4 shown, limiting bolts 103 parallel to the first stud 402 are inserted into both ends of the guide rail 1; the limiting bolts 103 are in threaded fit with the guide rail 1. During use, by inserting the limiting bolts 103 into both ends of the guide rail 1, the slider 4 can be prevented from detaching from the guide rail 1, and at the same time, by designing the threaded fit between the limiting bolts 103 and the guide rail 1, the slider 4 can be conveniently disassembled from the guide rail 1.
[0035] Embodiment Three:
[0036] On the basis of Embodiment Two, as Figures 6-7 shown, the connecting member 5 includes a pair of bearing sleeves 501 respectively fixedly sleeved on the other side edges of the two positioning frames 2; extension pieces 502 are vertically welded to the outer walls of the two bearing sleeves 501; the two extension pieces 502 are connected by a second stud 503; the second stud 503 is inserted through the two extension pieces 502, and the second stud 503 has a clearance fit with both extension pieces 502; nuts 504 are in threaded fit with both ends of the second stud 503. During use, by removing the nuts 504 from the second stud 503 and then removing the second stud 503 from the two extension pieces 502, the separation of the two positioning frames 2 can be achieved; when the two positioning frames 2 are in the same plane, at this time the two extension pieces 502 are arranged in parallel. First, insert the second stud 503 through the two extension pieces 502, then fit the two nuts 504 on the second stud 503 respectively, and shorten the two nuts 504 to the minimum, so that the two nuts 504 respectively abut against the two extension pieces 502, thereby realizing the locking of the two positioning frames 2, effectively ensuring the connection stability between the two positioning frames 2.
[0037] Embodiment Four:
[0038] On the basis of Embodiment Three, as Figure 6 andFigure 8 As shown in the figure, the limiting rod member 6 includes a pair of sliding sleeves 601 respectively sleeved on the upper and lower edges of the positioning frame 2, and a limiting rod 602 vertically arranged between the two sliding sleeves 601; on the outer walls of the two sliding sleeves 601, side connection sleeves 603 are vertically welded; at the upper and lower ends of the limiting rod 602, third studs 604 are vertically inserted; the two third studs 604 are in threaded cooperation with the limiting rod 602; one end of each of the two third studs 604 away from the limiting rod 602 is in threaded cooperation within the two side connection sleeves 603, and one end of each third stud 604 away from the limiting rod 602 slides through the circumferential side wall of the adjacent sliding sleeve 601 and abuts against the edge of the positioning frame 2. When in use, by rotating the third stud 604, one end of the third stud 604 away from the limiting rod 602 is separated from the edge of the positioning frame 2, and then by holding the limiting rod 602, the sliding sleeve 601 can be slid on the edge of the positioning frame 2, so as to adjust the distance between two adjacent limiting rods 602; when the position of the limiting rod 602 is adjusted, by manually rotating the third stud 604, one end of the third stud 604 away from the limiting rod 602 slides through the circumferential side wall of the adjacent sliding sleeve 601 and tightly abuts against the edge of the positioning frame 2, thereby locking the position of the limiting rod 602 and ensuring the use stability of the limiting rod 602.
[0039] Example Five:
[0040] Based on Example Four, as Figure 9 shown in the figure, a protective net 7 parallel to the positioning frame 2 is vertically arranged between the two guide rails 1; the protective net 7 is a conventional component in the art and is woven with nylon ropes, and the protective net 7 is connected to the two positioning frames 2 through conventional cable ties in the art. When in use, if the volume of the goods is small, in order to further improve the positioning effect on the goods, by connecting the protective net 7 to the positioning frame 2, the protective net 7 can increase the protection density of the goods, thereby ensuring the protection effect on the goods.
[0041] Example Six:
[0042] Based on Example Four, as Figure 10 shown in the figure, a baffle 8 parallel to the positioning frame 2 is vertically arranged between the two guide rails 1; the baffle 8 is connected to the adjacent positioning frame 2 through conventional cable ties in the art. When in use, if the volume of the goods is too small, in order to further improve the positioning effect on the goods, by connecting the baffle 8 to the positioning frame 2, the baffle 8 can effectively block the goods, thereby ensuring the protection effect on the goods.
