[0019] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] 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 scope of protection of the present utility model.

[0021] Example 1

[0022] like Figures 1-5 As shown, an adjustable vehicle profile indicator device for a semi-trailer includes a connecting seat 1 for connecting to the side of the vehicle. The connecting seat 1 has a U-shaped cross-section and its bottom is connected to the frame of the semi-trailer, resulting in high structural strength.

[0023] A telescopic structure is installed on the connecting seat 1. The telescopic structure includes an outer tube 2 connected to the base plate 11. The outer tube 2 is a rectangular tube and is welded and fixed to the connecting seat 1. An inner tube 5, also a rectangular tube, is fitted inside the outer tube 2. The inner tube 5 and the outer tube 2 are in sliding fit. The connection length between the outer tube 2 and the inner tube 5 is not less than 150mm to ensure connection stability. The wall thickness of both the outer tube 2 and the inner tube 5 is greater than 8mm. A length control structure is installed between the outer tube 2 and the inner tube 5. To ensure stability, the expansion range of the semi-trailer is fixed. The outline indicator structure switches between standard width and extended width to control the accuracy of the outline. The length control structure includes positioning pin holes 3 machined on the outer tube 2 and connecting holes 4 machined on the inner tube 5 to mate with the positioning pin holes 3. A positioning pin 15 passes between the positioning pin holes 3 and the connecting holes 4. In this embodiment, there are two positioning pin holes 3 and three connecting holes 4. When the two positioning pin holes 3 are connected to the two inner connecting holes 4, the outline indicator structure shows the standard width. Due to the extension of the outline indicator structure, during the semi-trailer's movement... Due to vibration and wind resistance, the indicator structure vibrates, leading to loose connections and a short service life. To address this issue, a vibration-damping connection device is installed between the outer tube 2 and the inner tube 5. This device includes an elastic pad 16 nested within the positioning pin hole 3. The elastic pad 16 is a vulcanized rubber sleeve with a large elastic modulus. The positioning pin hole 3 is widened to provide space for the installation of the elastic pad 16. The thickness of the elastic pad 16 is 2-3 mm greater than the wall thickness of the outer tube 2. During compression, it is pressed against the outer tube 2 and the inner tube 5, thus... A flexible connection is formed. A pressure plate 17 is installed on the outer end of the elastic pad 16, which cooperates with the elastic pad 16 to squeeze the elastic pad 16 inward. A pressure ring 18 that cooperates with the pressure plate 17 is installed on the positioning pin. In this embodiment, the positioning pin 15 is a bolt, and the pressure ring is a nut that cooperates with the bolt, which facilitates manufacturing and installation. By tightening the nut, the pressure plate 17 squeezes the elastic pad 16, thereby pressing the elastic pad 16 with the outer tube 2 and the inner tube 5 to form an elastic connection for shock absorption, so that the outline indicator device and the connecting seat 1 are connected stably for a long time.

[0024] The inner tube 5 is connected to a contour indicator structure at its end. The contour indicator structure includes a contour plate, a base plate 11, and a pressure frame 5 connected to the base plate 11. A contour marker, including a reflective marker, is installed inside the pressure frame 5 for daytime contouring. A contour light box 8 is connected to the outer end of the base plate 11, and a contour light is installed inside the contour light box 8 for nighttime or low visibility. In this embodiment, an elastic pressure plate 7 that cooperates with the contour marker is integrally formed on the pressure frame 5. The elastic pressure plate 7 cooperates with the edge of the contour marker. The pressure frame 5 is a stainless steel frame. The elastic pressure plate 7 is bent inward to form elasticity, which can press the edge of the contour marker tightly against the base plate 11. A support strip 19 is installed between the edges of the base plate 11 and the pressure frame 5. The base plate 11, the pressure frame 5, and the support strip 19 are fixed together by rivets or bolts. A connecting strip 12 that cooperates with the inner tube 5 is integrally formed in the middle of the pressure frame 5. The connecting strip 12 is connected to the base plate 11 by rivets or bolts.

[0025] In this embodiment, both the base plate 11 and the pressure frame 5 are made of stainless steel. The outer end of the base plate 11 is integrally formed with a bending part 13, and the outer end of the pressure frame 5 is integrally formed with a bending part 14. The bending part 13 and the bending part 14 form a marker light box 8 and are welded and fixed at the connection point to obtain a stable marker light box 8. A marker light is installed in the marker light box 8. The bending part 13 and the bending part 14 can improve the deformation resistance of the base plate 11 and the pressure frame 5. A light-transmitting opening 10 is processed on the side wall of the marker light box 8. A connecting plate 9 that cooperates with the end of the inner tube 5 is also installed on the side wall of the marker light box 8. The connecting plate 9 has an L-shaped cross-section. One wing is fixed to the marker light box 8, and the other wing forms a slot with the pressure frame 5. The end of the inner tube 5 is inserted into the slot and then fixed by bolts or welding to ensure the connection strength.

[0026] 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.
