DETAILED DESCRIPTION

[0026] The specific embodiments of the utility model are further described below in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.

[0027] "Top surface", "bottom", "bottom surface" take the normal use state of the heavy truck top deflector as reference, only for the convenience of describing the utility model and simplifying the description, and not indicating or implying that the indicated device or element must have a specific orientation, structure and operation, therefore, it cannot be understood as a limitation of the utility model.

[0028] As shown in Figures 1-7 A heavy truck top deflector, comprising front end mutually hinged deflector main body 1 and mounting rod 2, the end of mounting rod 2 is hinged with sliding seat 4, the end of deflector main body 1 is hinged with one end of adjusting rod 3, sliding seat 4 and adjusting rod 3 are slidingly matched, further comprising bolt 5 and locking block 6, limiting hole 401 is formed on sliding seat 4, a plurality of opening parts 301 are arranged at equal intervals along the extension direction of adjusting rod 3, bolt 5 penetrates limiting hole 401 and one of opening parts 301 in turn, and is threadedly connected with locking block 6;Plug-in part 503 with cylindrical shape is coaxially arranged on bolt 5, the outer diameter of plug-in part 503 is consistent with the hole diameter of limiting hole 401 and opening part 301, plug-in part 503 is plug-in matched with limiting hole 401 and one of opening parts 301.

[0029] The aforementioned top deflector body is typically installed on the top of the heavy truck cab to reduce wind resistance. In use, the mounting rod 2 is fixedly connected to the cab, and the adjusting rod 3 slides relative to the sliding seat 4, so that the limiting hole 401 on the sliding seat 4 is aligned with the opening 301 at different positions on the adjusting rod 3. The relative position between the adjusting rod 3 and the sliding seat 4 is locked by the bolt 5 and the locking block 6, thereby realizing the adjustment of the height of the tail of the deflector body 1.

[0030] Compared with the existing adjustment structure, the insertion part 503 passes through the opening part 301 and the limiting hole 401 in sequence to achieve alignment and limiting between the two, which can effectively improve the stability of the connection between the adjusting rod 3 and the sliding seat 4, prevent relative sliding after the two are fixed, and thus effectively resist the bumps when the vehicle is driving, and improve the stability of the installation of the deflector body 1; and the connection between the insertion part 503 and the opening part 301 and the limiting hole 401 can avoid the thread of the bolt 5 from contacting the sliding seat and the adjusting rod, reduce the wear of the thread, and extend the service life of the bolt 5.

[0031] Further improvements include, for example Figure 4 and 5 As shown, the adjusting rod 3 has a U-shaped groove structure, and the locking block 6 is fitted inside the adjusting rod 3. The locking block 6 is detachably provided with a nut 7 that is threadedly connected to the bolt 5. Specifically, the locking block 6 has a through hole 602 for the bolt 5 to pass through, and a second groove 603 is provided at the end of the through hole 602 that is away from the sliding seat 4. The nut 7 is fitted inside the second groove 603.

[0032] In the aforementioned top deflector main body device, the U-shaped groove structure of the adjusting rod 3, compared with the solid structure, can reduce the weight of the adjusting rod 3 while maintaining its structural strength, thus achieving a lightweight design for the top deflector main body device. The adjusting rod 3 can limit the locking block 6 to improve the stability of the locking block 6 installation. Then, the second groove 603 limits the nut 7 to prevent the nut 7 from loosening due to bumps during vehicle operation, thereby improving the stability of the deflector main body 1 installation. Furthermore, the nut 7 can be removed from the second groove 603 for individual replacement, thereby reducing the maintenance cost of the top deflector main body device.

[0033] Further improvements include, for example Figure 7 and 8 As shown, a first groove 601 is provided at one end of the through hole 602 near the sliding seat 4, and the first groove 601 is inserted into the end of the insertion part 503.

[0034] The first groove 601 is used to accommodate the end of the insertion part 503, so that the insertion part 503 can completely penetrate the opening part 301 and the limiting hole 401, thereby improving the firmness of the connection between the adjusting rod 3 and the sliding seat 4; and after the end of the insertion part 503 is inserted into the first groove 601, it achieves a mutual limiting effect, which can improve the firmness of the connection between the bolt 5 and the locking block 6, thereby further improving the stability of the connection between the adjusting rod 3 and the sliding seat 4, and ultimately improving the stability of the installation of the guide plate body 1.

[0035] Further improvements include, for example Figure 7 As shown, a stud portion 504 is coaxially provided at the front end of the plug portion 503, and a columnar abutment portion 501 is coaxially provided at the end of the plug portion 503. A handle portion 502 is provided on the side of the abutment portion 501 away from the plug portion 503. The outer diameter of the abutment portion 501 is larger than the diameter of the limiting hole 401, the outer diameter of the stud portion 504 is smaller than the outer diameter of the plug portion 503, and the inner diameter of the through hole 602 is the same as the outer diameter of the stud portion 504. An anti-slip layer is provided on the side of the abutment portion 501 near the sliding seat 4 and on the handle portion 502.

[0036] In the specific structure of the bolt 5, the handle 502 is convenient for the operator to hold and tighten the bolt 5; the clamping part 501 and the locking block 6 are used to press the adjusting rod 3 and the sliding seat 4 from both sides respectively, so that the two are tightly attached to each other and the connection between them is strengthened; the stud part 504 is used to connect with the nut 7 by thread, so that the bolt 5 is connected to the locking block 6; the anti-slip layer is a rubber layer, which can increase the friction between the bolt 5 and the sliding seat 4, thereby reducing the probability of the bolt 5 loosening due to vehicle bumps, so as to improve the stability of the deflector body 1 installation.

[0037] Further improvements include, for example Figure 5 As shown, adjacent openings 301 are interconnected by slots 302. The slots 302 are distributed along the extension direction of the adjusting rod 3. The width of the slots 302 is smaller than the inner diameter of the opening 301 and greater than or equal to the outer diameter of the bolt 5. The slots 302 provide a moving channel for the stud 504, allowing it to move between different openings 301. When the plug 503 switches to connect with different openings 301, it is only necessary to retract the plug 503 to the outside of the opening 301 without separating the stud 504 from the nut 7. This ensures that the bolt 5 and the locking block 6 remain connected when adjusting the relative position between the sliding seat 4 and the adjusting rod 3, facilitating subsequent re-tightening of the bolt 5 and the locking block 6 and improving the ease of adjusting the angle of the guide plate body 1.

[0038] Further improvements include, for example Figure 6As shown, the sliding seat 4 has a U-shaped groove structure. The groove openings of the sliding seat 4 and the adjusting rod 3 face the same direction, and the sliding seat 4 is semi-enclosed on the adjusting rod 3. The U-shaped groove structure of the sliding seat 4 can accommodate the adjusting rod 3 to enter its U-shaped opening, thereby realizing the mutual limiting effect between the sliding seat 4 and the adjusting rod 3, improving the stability of the connection between the two, and reducing the space occupied when the two are stacked, thus improving the convenience of using the main device of the top guide plate.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
