The rear protection device of the low flat-bed semitrailer is convenient for dismounting and taking out the tires at the middle part from the space, and is convenient for maintaining and replacing the tires; is convenient for emergency maintenance in long-distance transportation.
Description
Technical Field
The utility model relates to the field of semitrailers, in particular to a rear protection device of a low-flat-bed semitrailer.
Background
The existing low-flat-bed semitrailer has the advantages of strong bearing capacity, low bearing surface and the like. However, the ultra-low load-bearing surface would make the removal of the center tire extremely inconvenient. As shown in fig. 1: the disassembly of the four middle tires is limited by the rear protective structure of the semitrailer, the disassembly space of the middle tires is insufficient, and the disassembly is not easy; the middle tire cannot be disassembled and taken out from the space below the middle of the rear protection; increasing the difficulty and maintenance time of emergency maintenance in long-distance transportation.
In order to solve the above problems, people are always seeking an ideal technical solution.
SUMMERY OF THE UTILITY MODEL
In order to achieve the purpose, the utility model adopts the technical scheme that: a rear protection device of a low flat-bed semi-trailer comprises a rear protection vertical plate, wherein the middle part of the rear protection vertical plate is provided with a notch for a tire to vertically pass through; a license plate protective plate is arranged above the notch;
the gap is provided with a license plate mounting plate in a turnover manner through a hinge; the other side of the license plate mounting plate is connected to the rear protective vertical plate through a lock catch.
Based on the above, the license plate mounting plate can be horizontally connected to one side of the rear protection vertical plate in a turnover mode through the hinge.
Based on the above, for better protection, the width of the license plate protection plate is larger than that of the license plate installation plate.
Based on the above, in order to improve the safety, the two sides of the rear protective vertical plate are both provided with a rear tail lamp fixing frame and a triangular reflector mounting plate.
Based on the above, the width of the notch is smaller than the width of the middle part of the rear protection vertical plate.
Based on the above, for the sake of beauty and convenience for the tire to pass through, the two corners of the upper part of the notch are in arc transition.
Compared with the prior art, the rear protection device for the low-flat-bed semitrailer has substantial characteristics and progress, and particularly, the license plate mounting plate below the middle of the rear protection device is designed into an assembled structure. I.e. this space can be opened when needed; the tire of the middle part is convenient to be disassembled and taken out from the space; the maintenance and the tire replacement are convenient.
Further, with license plate board mounting panel one side of below in the middle of the back protection with hinge and back protection riser swing joint, the opposite side is connected with carrying out the hasp between the back protection riser with the metal hasp, make things convenient for the upset of this license plate board mounting panel to open and the locking is fixed. Therefore, the rear protection device of the low flatbed semi-trailer is novel in structure and convenient for emergency maintenance in long-distance transportation.

In the figure: 1. a rear protective vertical plate; 2. a hinge; 3. protecting the license plate; 4. a license plate mounting plate; 5. locking; 6. a rear tail lamp fixing frame; 7. a triangular reflector mounting plate; 8. a tire.
Detailed Description
The technical solution of the present invention is further described in detail by the following embodiments.
Example 1
The embodiment provides a rear protection device of a low flatbed semi-trailer, which comprises a rear protection vertical plate 1, wherein a notch for a tire 8 to vertically pass through is formed in the middle of the rear protection vertical plate 1, as shown in fig. 2 and 3; and a license plate protective plate 3 is arranged above the gap.
The gap is provided with a license plate mounting plate 4 through a hinge 2 in a turnover way; the other side of the license plate mounting plate 4 is connected to the rear protective vertical plate 1 through a lock catch 5.
The license plate mounting plate 4 can be horizontally connected to one side of the rear protective vertical plate 1 in a turnover mode through the hinge 2.
For better protection, the width of the license plate guard 3 is greater than the width of the license plate mounting plate 4.
And a rear tail lamp fixing frame 6 and a triangular reflector mounting plate 7 are arranged on two sides of the rear protective vertical plate 1.
In order to ensure the strength of the middle part of the rear vertical protection plate 1, the width of the notch is smaller than that of the middle part of the rear vertical protection plate 1.
And the two corners of the upper part of the notch are in arc transition.
Specifically, when the middle tire needs to be disassembled, the lock catch of the rear protection upper license plate mounting plate is only required to be opened, and the license plate mounting plate is turned over, so that the tire can be taken out backwards from the space. And convertible license plate mounting panel conveniently opens and the locking, can not influence the installation and the fixed of license plate, and the dismantlement of tire in the middle of very big making things convenient for reduces and leads to tire dismantlement time because of the space is not enough, improves the change efficiency of tire.
Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the utility model or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the utility model as defined by the appended claims.
