DETAILED DESCRIPTION

[0022] In order to make the above objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many different ways from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0023] Please refer to Figs. 1 to 4 The embodiment of the present application provides a kind of adjustable side protection device of towing vehicle, including frame 1, hinged seat one 2 and two hinged seat two 3 are hinged on frame 1, two hinged seat 3 are located in hinged seat one 2 both sides and symmetrically arranged, connecting frame 4 is installed on hinged seat one 2, square sleeve 5 is installed on frame 1, square slide rod 6 is slidably connected in square sleeve 5, spring is installed in square sleeve 5, the output end of spring is connected with square slide rod 6, connecting frame 4 is cooperatively arranged with square slide rod 6, T-shaped frame 7 is slidably connected in connecting frame 4, T-shaped frame 7 is cooperatively arranged with square slide rod 6, sleeve 8 is rotatably installed on hinged seat two 3, sleeve 8 is inclinedly arranged, sleeve rod 9 is slidably connected in sleeve 8, the end of sleeve rod 9 away from sleeve 8 is hinged with T-shaped frame 7, the bottom of frame 1 is provided with fixed mechanism for limiting connecting frame 4, further include the limiting mechanism of sleeve rod 9 in the sliding of sleeve 8, fixed mechanism can be rotatable L-shaped plate, L-shaped plate can be loaded to connecting frame 4 after bending connecting frame 4, so that it can not rotate.

[0024] In the embodiment, the inclined arrangement of sleeve 8 makes that the hinged point of sleeve rod 9 slidably connected in it and T-shaped frame 7 can be located at both ends of T-shaped frame 7 T-shaped top or T-shaped bending place, and two kinds of inclined connection modes can constitute triangular stable structure to keep the strength of side protection device, when the height of side protection device needs to be adjusted, first make the limiting mechanism no longer limit the sliding of sleeve rod 9, so that T-shaped frame 7 can be manually driven to slide up and down in connecting frame 4, when T-shaped frame 7 moves, due to the rotatable connection of sleeve 8 and hinged seat two 3 and the hinge of sleeve rod 9 and T-shaped frame 7, sleeve rod 9 can slide in sleeve 8 cooperatively with T-shaped frame 7 and the change of inclination angle of both can be cooperated, after adjustment, the limiting mechanism can limit sleeve rod 9 again, so that T-shaped frame 7 can be pulled by sleeve rod 9 and no longer slide; when T-shaped frame 7 slides to the top end of connecting frame 4, it can extrude square slide rod 6 slidably in square sleeve 5, so that it slides back into square sleeve 5, so that connecting frame 4 can be driven by hinged seat one 2 and sleeve 8 can be rotated by hinged seat two 3, so that the whole side protection device can be rotated to the bottom of frame 1, and then connecting frame 4 can be fixed by the fixed mechanism at the bottom of frame 1; the right angle of both sides of connecting frame 4 and square slide rod 6 abuts, so that the whole connecting frame 4 is not easy to rotate.

[0025] In some embodiments, in order to make the side protection device lightweight, to improve the economy of the whole vehicle, the T-shaped frame 7 and the sleeve rod 9 can be hollow. The hollow setting of the T-shaped frame 7 and the sleeve rod 9 cooperates with the hollow connecting frame 4 and the sleeve 8, so that the overall weight of the side protection device is lighter, and the sleeve 8, the sleeve rod 9 and the T-shaped frame 7 form a triangular stable structure, so that the self-protection performance of the side protection device does not decrease.

[0026] In some embodiments, in order to fix the height of the side protection device after lifting, a limiting mechanism is provided, including a limiting frame 10 and a limiting hole 11, a plurality of limiting holes 11 are arranged on the sleeve rod 9, and a threaded rod 12 is inserted at both ends of the limiting frame 10. The threaded rod 12 is inserted into the limiting hole 11, and one end of the threaded rod 12 protruding from the limiting frame 10 and the limiting hole 11 is threadedly connected with a nut 13. Thus, the two sleeve rods 9 are fixed by the threaded rod 12 on the limiting frame 10, so that the inclination angle of the two sleeves 9 is fixed, so that the sleeve rod 9 cannot slide out of the sleeve 8, and the sleeve rod 9 can pull the T-shaped frame 7 to prevent it from moving up and down. The threaded rod 12 is only connected with the nut 13, which is convenient for disassembly and assembly of the threaded rod 12.

[0027] In some embodiments, in order to facilitate the extrusion of the T-shaped frame 7 to the square slide rod 6, so that it can be retracted into the square sleeve 5, the lower end of the square slide rod 6 is provided with a chamfer.

[0028] In some embodiments, in order to facilitate the rotation of the hinge seat one 2 and the hinge seat two 3, the hinge seat one 2 and the hinge seat two 3 are provided with a round corner.

[0029] In some embodiments, in order to further improve the stability of the connecting frame 4 during protection, the F-shaped abutting plate 14 is installed on the connecting frame 4, the square slide rod 6 is provided with a matching groove 15, and the F-shaped abutting plate 14 is matched with the square slide rod 6. The inner corner of the top of the F-shaped abutting plate 14 abuts with one corner of the top of the square slide rod 6, and the short horizontal plate on the F-shaped abutting plate 14 is clamped in the matching groove 15, so that the connecting frame 4 is not easy to bend. When the connecting frame 4 is bent and rotated back, the square slide rod 6 can be first pressed back into the square sleeve 5 by using a tool, and then the T-shaped frame 7 is slid to the connecting frame 4 after abutting with the F-shaped abutting plate 14. At this time, the square slide rod 6 abutting with the T-shaped frame 7 will not pop out due to the extrusion of the spring, and after the connecting frame 4 is completely rotated back, the T-shaped frame 7 slides down, the square slide rod 6 pops out again, and the F-shaped abutting plate 14 abuts with the square slide rod 6 again.

[0030] In some embodiments, in order to make the connecting frame 4 not easy to bend and facilitate the square slide rod 6 to slide back into the square sleeve 5 when it is extruded, the square sleeve 5 can be symmetrically provided with two. Thus, the sliding stroke of the square slide rod 6 is shortened when it is extruded, which facilitates its sliding back.

[0031] Any combination of the technical features in the above embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is understood that the scope of the present disclosure includes all possible combinations.

[0032] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
