[0002] The main body of the heavy truck top deflector is an air deflector device installed on the top of the heavy truck cab. Its main function is to reduce air resistance when the vehicle is moving.

[0003] Patent CN221293851U discloses a top fairing lifting and adjusting mechanism, which adjusts the height of the tail end of the top fairing through a height adjusting component. In the height adjusting component, a combination of locking bolts and locking nuts is used to fix the lifting seat and the lifting bracket to lock the angle of the top fairing. However, vehicles inevitably experience bumps during driving, and long-term bumps can cause the locking bolts and locking nuts to loosen, which in turn causes the top fairing to loosen, affecting the air guiding effect of the top fairing. In severe cases, the top fairing may even fall off, affecting driving safety.

[0004] Therefore, it is necessary to improve the existing anti-loosening top guide plate for heavy trucks. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects in the existing technology and provide a top guide plate for heavy trucks that prevents loosening, thereby improving the stability of the installation of the top guide plate body.

[0006] To achieve the above objectives, the specific technical solution of the anti-loosening heavy truck top guide plate of this utility model is as follows:

[0007] A top guide plate for heavy trucks designed to prevent loosening includes a guide plate body, the front end of which is hinged to the front end of a mounting rod, and the rear end of which is hinged to the top end of an adjusting rod. The rear end of the mounting rod is hinged to a sliding seat, and the sliding seat slides with the adjusting rod. The guide plate also includes a fastening assembly for fixing the sliding seat and the adjusting rod. The fastening assembly includes a bolt and a connecting block with a threaded hole. The bolt is coaxially provided with an anti-loosening ring. One of the anti-loosening ring and the sliding seat has an interlocking strip, and the other has an interlocking groove. The interlocking strip and the interlocking groove engage with each other to limit the bolt's position. The adjusting rod has a U-shaped groove structure, and the connecting block is located inside the adjusting rod and engages with it.

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0026] The terms "top surface," "bottom surface," and "flush surface" refer to the normal operating state of the main body of the heavy truck top guide plate device. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figure 1-3 As shown, a non-loosening top guide plate for heavy trucks includes a guide plate body 1, the front end of which is hinged to the front end of a mounting rod 2, and the end of which is hinged to the top end of an adjusting rod 3. The end of the mounting rod 2 is hinged to a sliding seat 4, and the sliding seat 4 is slidably engaged with the adjusting rod 3. It also includes a fastening assembly for fixing the sliding seat 4 and the adjusting rod 3. Figure 7 As shown, the fastening assembly includes a bolt 5 and a connecting block 7 with a threaded hole 701. The bolt 5 is coaxially provided with an anti-loosening ring 6. One of the anti-loosening ring 6 and the sliding seat 4 is provided with an interlocking strip 603, and the other is provided with an interlocking groove 402. The interlocking strip 603 and the interlocking groove 402 engage with each other to limit the bolt 5. The adjusting rod 3 has a U-shaped groove structure, and the connecting block 7 is located inside the adjusting rod 3 and is interlocked with the adjusting rod 3.

[0028] The aforementioned deflector body is installed on the roof of the truck cab to reduce wind resistance. The sliding seat 4 has a second limiting hole 401, and the adjusting rod 3 has multiple first limiting holes 301 arranged at equal intervals along its extension direction. Bolts 5 pass through the second limiting hole 401 and one of the first limiting holes 301 sequentially and are threadedly connected to the threaded hole 701. During adjustment, the bolts 5 are separated from the connecting block 7 and then pulled out from the first and second limiting holes 301. The adjusting rod 3 then slides relative to the sliding seat 4. During this sliding process, the height of the end of the deflector body 1 changes until a predetermined angle is reached. At this point, the second limiting hole 401 and one of the first limiting holes 301 must be aligned. Then, the bolts 5 and connecting block 7 are reset and threadedly connected to each other, thus fixing the sliding seat 4 and the adjusting rod 3 together. This ultimately locks the position of the deflector body 1 and completes the adjustment of the angle of the deflector body 1.

[0029] Compared with the existing deflector body device, after the bolt 5 and the connecting block 7 are threaded together and the sliding seat 4 and the adjusting rod 3 are locked, the interlocking strip 603 on the anti-loosening ring 6 and the interlocking groove 402 on the sliding seat 4 are in a mutually engaged state, thereby achieving the limiting effect on the bolt 5 and preventing the bolt 5 from loosening during vehicle bumps; and the connecting block 7 is limited by the adjusting rod 3 to prevent the connecting block 7 from loosening during vehicle bumps; thus, the stability between the bolt 5 and the connecting block 7 can be guaranteed, thereby improving the stability of the connection between the sliding seat 4 and the adjusting rod 3, and ultimately improving the stability of the deflector body 1 installation, and improving the safety and economy of vehicle driving.

[0030] Further improvements include, for example Figure 2-4 As shown, the sliding seat 4 has a U-shaped groove structure, and the groove openings of the sliding seat 4 and the adjusting rod 3 face the same direction. The sliding seat 4 is semi-enclosed on the adjusting rod 3. Both the sliding seat 4 and the adjusting rod 3 have U-shaped groove structures, which can reduce their weight while maintaining their structural strength. Furthermore, when the two are stacked together, they can reduce the space occupied and improve the ease of use of the main body of the top guide plate. In addition, the U-shaped groove structure can facilitate mutual restraint between the two, improving the stability of the connection structure.

[0031] Further improvements include, for example Figure 4-6As shown, multiple interlocking bars 603 are evenly spaced around the axis of the anti-detachment ring 6, and the interlocking bars 603 are distributed radially along the anti-detachment ring 6; multiple interlocking grooves 402 are evenly spaced around the axis of the second limiting hole 401, and the interlocking grooves 402 are distributed radially along the second limiting hole 401; the bolt 5 includes a stud portion 503, and a columnar abutment portion 502 is coaxially provided at the end of the stud portion 503. The outer diameter of the abutment portion 502 is larger than the diameter of the second limiting hole 401. The anti-detachment ring 6 is coaxially slidably disposed on the abutment portion 502. On the tight part 502, a limiting member and an elastic member are provided between the anti-detachment ring 6 and the tight part 502; the elastic member is a spring 604, and a handle part 501 is provided at one end of the tight part 502 away from the stud part 503. The spring 604 is sleeved on the outer periphery of the tight part 502, and its two ends are respectively connected to the handle part 501 and the anti-detachment ring 6; the limiting member includes a limiting groove 504 opened axially on the outer periphery of the tight part 502, and a limiting block 602 provided on the inner wall of the anti-detachment ring 6. The limiting block 602 and the limiting groove 504 are slidably engaged.

[0032] The handle 501 allows for easy manual tightening of the bolt 5 during adjustment. The clamping part 502 and the connecting block 7 clamp the sliding seat 4 and the adjusting rod 3 from both sides. The limiting groove 504 and the limiting block 602 cooperate to restrict the relative rotation between the anti-detachment ring 6 and the clamping part 502. The specific usage is as follows: when tightening the bolt 5, manually push the anti-detachment ring 6 along the clamping part 502 towards the handle 501 until the bolt 5 is tightened, then release the anti-detachment ring. Ring 6, pushed by spring 604, approaches sliding seat 4, and finally the spring force of spring 604 presses the anti-loosening ring 6 against sliding seat 4, so that interlocking groove 402 and interlocking bar 603 are engaged with each other, thereby limiting the bolt 5 and preventing it from loosening; when it is necessary to loosen bolt 5, the anti-loosening ring 6 needs to be pushed towards handle part 501 first, so that interlocking groove 402 and interlocking bar 603 are separated from each other, thereby unlocking bolt 5 and sliding seat 4.

[0033] Further improvements include, for example Figure 6 As shown, a flange 601 is provided circumferentially on the outer periphery of the anti-detachment ring 6. The flange 601 provides a force point for manually sliding the anti-detachment ring 6, thereby improving the ease of moving the anti-detachment ring 6 and ultimately improving the ease of adjusting the angle of the guide plate body 1.

[0034] Further improvements include, for example Figure 6As shown, the first direction is along the tightening direction of bolt 5, and the interlocking bar 603 has a chamfer on its side facing forward in the first direction. The chamfer releases the engagement between the interlocking groove 402 and the interlocking bar 603 when bolt 5 is tightened. Combined with the pushing force of spring 604 on the anti-detachment ring 6, it eliminates the need to continuously manually push the anti-detachment ring 6 towards the handle 501 when tightening bolt 5, thereby improving the ease of operation when adjusting the angle of the top guide plate main body device.
