[0002] In the field of modern logistics and transportation, with the rapid development of my country's economic construction, the number of heavy-duty flatbed semi-trailers is constantly increasing. In metallurgical transportation companies, heavy-duty flatbed semi-trailers need to transport various products from steel mills. During transportation, the vehicle will experience various driving states such as acceleration, deceleration, braking, and turning. The front windshield of the semi-trailer is an essential barrier to prevent the goods from sliding forward or falling off under the action of inertia.

[0003] The existing technology has the following drawbacks: Because relevant personnel need to confirm information about the goods, they must climb from the ground to the semi-trailer's loading platform. Currently, cargo handlers generally use a method of climbing up and down from near the tires on one side of the semi-trailer to access the loading platform. This method poses certain safety hazards. The traditional semi-trailer front panel structure is relatively fixed and lacks a flexible adjustment mechanism. When personnel are loading / unloading goods or performing equipment maintenance, they are often restricted by the front panel structure, making operation inconvenient and inefficient. Furthermore, when the front panel needs repair, replacement, or configuration adjustment according to special transportation tasks, the installation and disassembly process of the traditional front panel is complex and cumbersome, usually requiring specialized tools and a large amount of manpower, consuming a considerable amount of time. This not only increases maintenance costs and vehicle downtime but also seriously affects the continuity and timeliness of transportation operations, making it difficult to meet the rapid turnover requirements of modern efficient logistics transportation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a foldable semi-trailer windshield, including a platform 1. A fixed plate 2 is fixedly connected to the top of the platform 1. The platform 1 is the load-bearing area of ​​the existing semi-trailer, and goods can be stacked on the platform 1 for subsequent transportation. A fixed sleeve 3 is fixedly connected to the outer wall of the fixed plate 2. An insertion tube 4 is inserted into the inner wall of the fixed sleeve 3. The inner wall of the fixed sleeve 3 has slots corresponding to the insertion tube 4 and the wedge 8, which can satisfy the insertion tube 4 to be inserted into the fixed sleeve 3 and also allow the wedge 8 to rotate along the fixed sleeve 3. A folding plate 5 is fixedly connected to the outer wall of the insertion tube 4. The folding plate 5 occupies about 1 / 3 of the area of ​​the fixed plate 2. The folding plate 5 will not obstruct the movement of personnel during the process of getting on and off. A limit mechanism is provided on the inner wall of the insertion tube 4. A guide tube 9 is fixedly connected to the inner wall of the insertion tube 4. The guide tube 9 allows the moving plate 7 to move laterally without deviation of the movement trajectory. A connecting component is provided on the outer wall of the folding plate 5.

[0033] The limiting mechanism includes a movable plate 7, which is slidably connected to the inner wall of the insertion tube 4. The insertion tube 4 has a corresponding slot for the movable plate 7, which allows the movable plate 7 to move laterally along the insertion tube 4. A wedge block 8 is fixedly connected to the right end of the movable plate 7. The wedge block 8 is inclined. When the inclined surface is squeezed, the wedge block 8 will move the movable plate 7 to the left. The left end of the movable plate 7 is elastically connected to the insertion tube 4 through a return spring 6.

[0034] Reference Figure 1 , Figure 2 and Figure 5 The connecting assembly includes a locking sleeve 10, which is fixedly connected to the outer wall of the folding plate 5. The outer wall of the locking sleeve 10 has two collars, allowing the moving tube 12 to move up and down and rotate along the inner wall of the collars. The locking sleeve 10 mainly connects the moving tube 12. A stop block 11 is fixedly connected to the outer wall of the locking sleeve 10, which prevents the moving tube 12 from moving upward. When the moving tube 12 is not in contact with the stop block 11 and is not blocked by it, the moving tube 12 can move upward. The moving tube 12 is movably connected to the inner wall of the locking sleeve 10. Two sets of locking sleeves 10, moving tubes 12, and stop blocks 11 are provided, respectively on the outer wall of the folding plate 5. Figure 5 As shown, the moving tube 12 is connected to a positioning block 13. There are two sets of positioning blocks 13. The left positioning block 13 allows the folding plate 5 to be folded and connected to the moving tube 12. At this time, the positioning block 13 is connected to the right positioning block 13 to ensure that the folding plate 5 and the fixed plate 2 are unfolded. The positioning block 13 is fixedly connected to the outer wall of the platform 1, and the bottom end of the moving tube 12 is in contact with the top end of the platform 1.

[0035] Reference Figures 2-4 The left end of the movable plate 7 is fixedly connected to one end of the return spring 6. When the movable plate 7 moves to the left, it will compress the return spring 6. When resetting, the reverse elastic force of the return spring 6 will carry the movable plate 7 to reset. The other end of the return spring 6 is fixedly connected to the inner wall of the left end of the insertion tube 4. The movable plate 7 is slidably connected to the outer wall of the guide tube 9. The wedge 8 passes through and is slidably connected to the inner wall of the insertion tube 4. The wedge 8 is inserted into the inner wall of the fixed sleeve 3.

[0036] Working principle: First, when it is necessary to fold the folding plate 5 to facilitate personnel getting on and off platform 1, simply rotate the moving tube 12 and move the moving tube 12 upward to separate the moving tube 12 from the positioning block 13 and release the restriction on the folding plate 5. Then, allow the folding plate 5 to rotate 180 degrees. After the folding plate 5 is rotated, the moving tube 12 on the outer wall coincides with the left end positioning block 13. Then, insert the moving tube 12 into the left end positioning block 13 and rotate it. Use the stop block 11 to block the moving tube 12 so that it cannot move upward, thus completing the restriction after the folding plate 5 is folded. The unfolding method of the folding plate 5 is the same. You can operate according to the above steps.

[0037] When the folding plate 5 needs to be removed from the fixed plate 2, the moving plate 7 can be moved to the left, bringing the wedge 8 along with it. The wedge 8 is then retracted into the inner wall of the insertion tube 4 and compresses the return spring 6. Then, the entire folding plate 5, along with the insertion tube 4 and the moving plate 7, is moved upwards. After the insertion tube 4 is separated from the fixed sleeve 3, the moving plate 7 is released, and the return spring 6 is used to reset the moving plate 7 and the wedge 8. When the folding plate 5 needs to be installed on the fixed plate 2, the side walls of the fixed plate 2 and the folding plate 5 are placed together, and the insertion tube 4 is inserted into the fixed sleeve 3 from top to bottom. The top of the fixed sleeve 3 is pressed against the inclined surface of the wedge 8, and the wedge 8 moves to the left with the moving plate 7, compressing the return spring 6. When the wedge 8 and the inner wall groove of the fixed sleeve 3 coincide, the return spring 6 is used to reset the moving plate 7 and the wedge 8 to the right, allowing the wedge 8 to be inserted into the inner wall groove of the fixed sleeve 3 to complete the limiting.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
