DETAILED DESCRIPTION
[0018] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0019] Example 1:
[0020] like Figures 1-5 As shown, this embodiment provides a novel fender mechanism for a municipal fire truck, including a fixed base 1, a main fender 2, a connecting rod 3, a connecting rod 4, an adjustable connecting rod 5, a rotating foot pedal 6, and a gas spring 7. The fixed base 1 is fixed to the truck bed in front of and behind the tires. The fixed base 1 is provided with a first hinge position 8, a second hinge position 9, and a third hinge position 10. The main fender 2 is L-shaped, and the horizontal section 2.1 of the main fender 2 is hinged to the first hinge position 8 near its free end. The main fender 2 is provided with a fourth hinge position 11, a fifth hinge position 12, and a third hinge position 10. Sixth hinge position 13, one end of the rotating foot pedal 6 is hinged to the sixth hinge position 13, one end of the gas spring 7 is hinged to the second hinge position 9, and the other end is hinged to the fourth hinge position 11, one end of the connecting rod 3 is hinged to the third hinge position 10, one end of the adjustable connecting rod 5 is hinged to the fifth hinge position 12, one end of the linkage rod 4 is hinged to the rotating foot pedal 6 at the eighth hinge position 15, and the other ends of the connecting rod 3, the adjustable connecting rod 5 and the linkage rod 4 are all hinged to the seventh hinge position 16. The main fender 2 rotates 90 degrees clockwise, which drives the rotating foot pedal 6 to rotate 90 degrees counterclockwise.
[0021] This technical solution is simple, convenient, and quick to operate, saving firefighters a significant amount of rescue time. During operation, firefighters simply flip down the main fender 2, which triggers the linkage 4 to rotate the rotating foot pedal 6. When the main fender 2 reaches the correct position, the rotating foot pedal 6 also reaches the correct position; that is, a 90-degree clockwise rotation of the main fender 2 causes the rotating foot pedal 6 to rotate 90 degrees counterclockwise. Figure 3As shown, the firefighter directly steps on the rotating footboard 6 to take the equipment at the high position in the upper tire equipment box in the shortest time. The technical solution can provide convenience for the firefighter to take the equipment at the high position, and the main fender 2 and the rotating footboard 6 can be quickly retracted after the equipment is taken. When the firefighter takes the equipment and needs to turn back the rotating footboard 6, the main fender 2 is only needed to be turned back to the original position. In the process of turning back of the main fender 2, the connecting rod 4 pulls the rotating footboard 6 to automatically turn back to the original position. Only one action of turning over the main fender 2 can realize the simultaneous resetting of the main fender 2 and the rotating footboard 6, and the problem of collision between the fender and the tire caused by the non-turning of the footboard due to the misoperation of the existing fender is solved, and the advantages of anti-stupidity and anti-misoperation are achieved. In addition, the gas spring 7 can effectively offset part of the gravity of the main fender 2 in the process of opening the rotation of the main fender 2, so that the turning process is more safe and reliable, light and labor-saving.
[0022] Embodiment 2:
[0023] This embodiment is optimized on the basis of the above-mentioned embodiment 1.
[0024] In order to bypass obstacles during the movement of the workpiece, the connecting rod 4 is provided with an obstacle avoidance recess 4.1.
[0025] Embodiment 3:
[0026] This embodiment is optimized on the basis of the above-mentioned embodiment 1.
[0027] In order to facilitate stepping and save space, the inner side of the main fender 2 has a storage groove 14. When the rotating footboard 6 is turned counterclockwise to 90 degrees, the rotating footboard 6 is located in the storage groove 14 and the upper end faces of the two are flush.
[0028] Embodiment 4:
[0029] This embodiment is optimized on the basis of the above-mentioned embodiment 1.
[0030] The first hinge position 8 is located obliquely below the second hinge position 9, and the third hinge position 10 is located obliquely below the first hinge position 8.
[0031] Embodiment 5:
[0032] This embodiment is optimized on the basis of the above-mentioned embodiment 1.
[0033] The fourth hinge position 11 is located near the first hinge position 8, the fourth hinge position 11 is located above the third hinge position 10, the fifth hinge position 12 is located at the corner of the main fender 2, the sixth hinge position 13 is located at the upper end of the vertical section 2.2 of the main fender 2, and the eighth hinge position 15 is located near the sixth hinge position 13.
[0034] In the technical solution, the fixed base 1 is hinged with the main wing panel 2, the gas spring 7 and the connecting rod 3, the main wing panel 2 is hinged with the gas spring 7, the adjustable connecting rod 5 and the rotating foot pedal 6, the connecting rod 3, the adjustable connecting rod 5 and the connecting rod 4 are hinged at the same hinge position, and the connecting rod 4 is hinged with the rotating foot pedal 6. The gas spring 7, the fixed base 1 and the main wing panel 2 balance the gravity of the main wing panel 2, and the connecting rod 3, the connecting rod 4, the adjustable connecting rod 5 and the rotating foot pedal 6 complete the mechanism action. The fixed base 1, the connecting rod 3, the adjustable connecting rod 5 and the main wing panel 2 form a four-bar mechanism A, and the main wing panel 2, the adjustable connecting rod 5, the connecting rod 4 and the rotating foot pedal 6 form another four-bar mechanism B.
[0035] When the main wing panel 2 needs to be turned down, the firefighter turns the main wing panel 2 by hand, and the main wing panel 2 rotates around the first hinge position 8. In the four-bar mechanism A, the rotation of the main wing panel 2 drives the connecting rod 3 to rotate, and the adjustable connecting rod 5 to move and rotate. In the four-bar mechanism B, the relative rotation of the adjustable connecting rod 5 relative to the main wing panel 2 drives the connecting rod 4 to move and rotate. The movement of the connecting rod 4 drives the rotating foot pedal 6 to rotate around the sixth hinge position 13. When the main wing panel 2 rotates 90 degrees clockwise, the connecting rod 4 drives the rotating foot pedal 6 to rotate 90 degrees counterclockwise around the sixth hinge position 13, as shown in FIG. 2, so that the firefighter can step on the rotating foot pedal 6 to reach the equipment at a high place. Similarly, after taking the equipment, the firefighter turns the main wing panel 2 back, and each rod moves to the initial position in the same way. Figure 3
[0036] The performance of the application is advanced, which is embodied in the interaction of seven workpieces, forming a four-bar mechanism (the gas spring 7, the fixed base 1 and the main wing panel 2) that is relatively independent and balanced in gravity. In addition, only one action of the firefighter is needed, and the interaction of six rods (the fixed base 1, the main wing panel 2, the connecting rod 3, the connecting rod 4, the adjustable connecting rod 5 and the rotating foot pedal 6) realizes the required multi-rod movement. The simple structure can realize complex movement, and the structure is simple, saves space and is flexible and controllable.
[0037] Finally, it should be noted that the above is only a preferred embodiment of the application and is not intended to limit the protection scope of the application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the application shall be included in the protection scope of the application.
