Detailed implementation mode
[0020] In order to clearly and completely describe the purpose and technical solution of the present utility model and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present utility model.
[0021] Embodiment 1: Please refer to Figures 1 to 5 , the present utility model provides a technical solution: A fiberglass shell for a new energy bus air conditioner, including: A through hole 2 is opened on the surface of the fiberglass shell body 1 of the new energy bus air conditioner. A screw 3 is arranged in the through hole 2. An anti-loosening ring installation groove 4 is opened on the surface of the fiberglass shell body 1 of the new energy bus air conditioner. One end of an anti-loosening ring 5 is movably inserted into the anti-loosening ring installation groove 4. The other end of the anti-loosening ring 5 extends out of the anti-loosening ring installation groove 4 and is sleeved on the nut of the screw 3. The anti-loosening ring installation groove 4 is in a ring-shaped groove structure. The anti-loosening ring 5 is in a ring-shaped plate structure. The anti-loosening ring installation groove 4 and the anti-loosening ring 5 cooperate with each other. The inner ring of the anti-loosening ring 5 cooperates with the nut of the screw 3.
[0022] During actual use, after inserting the screw 3 into the through hole 2 opened on the surface of the fiberglass shell body 1 of the new energy bus air conditioner, tighten the screw 3 into the screw hole reserved on the new energy bus body at the bottom of the fiberglass shell body 1 of the new energy bus air conditioner. During the tightening process, make the anti-loosening ring 5 completely retract into the anti-loosening ring installation groove 4 to avoid the anti-loosening ring 5 hindering the tightening of the screw 3. When the screw 3 is about to be tightened, slightly tighten the screw 3 in the tightening direction to align the nut of the screw 3 with the inner ring of the anti-loosening ring 5, and then make one end of the anti-loosening ring 5 extend out of the anti-loosening ring installation groove 4 and be sleeved on the nut of the screw 3. The other end of the anti-loosening ring 5 stays in the anti-loosening ring installation groove 4. Then the anti-loosening ring installation groove 4 limits the anti-loosening ring 5 so that the anti-loosening ring 5 cannot rotate, and the anti-loosening ring 5 limits the nut of the screw 3 so that the screw 3 cannot rotate, thus realizing anti-loosening of the screw 3 and avoiding loosening of the screw 3 due to shaking.
[0023] Embodiment 2: On the basis of Embodiment 1, in order to control the position of the anti-loosening ring 5, a lever slot 6 is formed on the surface of the FRP housing body 1 of the new energy bus air conditioner. The lever slot 6 is in the structure of a rectangular groove body, and the lever slot 6 communicates with the anti-loosening ring installation groove 4. A lever 7 is slidably connected in the lever slot 6. The lever 7 is in the structure of a rectangular rod body. One end of the lever 7 is fixed on the surface of the anti-loosening ring 5, and the other end of the lever 7 extends out of the lever slot 6. A first elastic rod mounting seat 8 is fixed at the bottom end of the anti-loosening ring 5, and a second elastic rod mounting seat 9 is fixed on the inner wall of the anti-loosening ring installation groove 4. The first elastic rod mounting seat 8 and the second elastic rod mounting seat 9 are in the structure of blocks, and inclined surfaces are provided on the surfaces of the first elastic rod mounting seat 8 and the second elastic rod mounting seat 9. An elastic rod 10 is fixed between the inclined surface of the first elastic rod mounting seat 8 and the inclined surface of the second elastic rod mounting seat 9. The elastic rod 10 is in the structure of a circular rod body. A support rod 11 is fixed on the inner wall of the anti-loosening ring installation groove 4. The support rod 11 is in the structure of a circular rod body. The elastic rod 10 abuts against the surface of the support rod 11.
[0024] When it is necessary to completely retract the anti-loosening ring 5 into the anti-loosening ring installation groove 4, the lever 7 is pulled downwards. The lever 7 moves downwards in the lever slot 6, driving the anti-loosening ring 5 to move downwards so that the anti-loosening ring 5 is completely retracted into the anti-loosening ring installation groove 4. When the anti-loosening ring 5 is completely retracted into the anti-loosening ring installation groove 4, the first elastic rod mounting seat 8 moves downwards following the anti-loosening ring 5, which causes one end of the elastic rod 10 to move downwards following the first elastic rod mounting seat 8, while the other end of the elastic rod 10 is fixed on the second elastic rod mounting seat 9 and remains stationary in the anti-loosening ring installation groove 4. Then the elastic rod 10 bends under the abutment of the support rod 11. When it is necessary to extend one end of the anti-loosening ring 5 out of the anti-loosening ring installation groove 4, just release the lever 7, and the elastic rod 10 returns to its original state under its own elastic action. The restoration of the elastic rod 10 causes the first elastic rod mounting seat 8 to move upwards to return to its original position, and then the first elastic rod mounting seat 8 pushes the anti-loosening ring 5 upwards to its original position, so that one end of the anti-loosening ring 5 extends out of the anti-loosening ring installation groove 4.
[0025] During actual use, after inserting the screw 3 into the through hole 2 formed on the surface of the FRP shell body 1 of the new energy bus air conditioner, the screw 3 is tightened into the screw hole reserved on the bottom end of the new energy bus body of the FRP shell body 1 of the new energy bus air conditioner. During the tightening process, the anti-loosening ring 5 is completely retracted into the anti-loosening ring installation groove 4 to prevent the anti-loosening ring 5 from obstructing the tightening of the screw 3. When the screw 3 is about to be tightened, the screw 3 is slightly tightened further in the tightening direction so that the nut of the screw 3 is aligned with the inner ring of the anti-loosening ring 5. Then, one end of the anti-loosening ring 5 extends out of the anti-loosening ring installation groove 4 and is sleeved on the nut of the screw 3, and the other end of the anti-loosening ring 5 stays in the anti-loosening ring installation groove 4. Then, the anti-loosening ring installation groove 4 limits the anti-loosening ring 5 to prevent the anti-loosening ring 5 from rotating, and the anti-loosening ring 5 also limits the nut of the screw 3 to prevent the screw 3 from rotating, thereby realizing anti-loosening of the screw 3 and preventing the screw 3 from loosening due to shaking. When it is necessary for the anti-loosening ring 5 to be completely retracted into the anti-loosening ring installation groove 4, the lever 7 is toggled downward. The lever 7 moves downward in the lever groove 6, driving the anti-loosening ring 5 to move downward so that the anti-loosening ring 5 is completely retracted into the anti-loosening ring installation groove 4. When the anti-loosening ring 5 is completely retracted into the anti-loosening ring installation groove 4, the first elastic rod mounting seat 8 moves downward following the anti-loosening ring 5. This causes one end of the elastic rod 10 to move downward following the first elastic rod mounting seat 8, while the other end of the elastic rod 10 is fixed to the second elastic rod mounting seat 9 and remains stationary in the anti-loosening ring installation groove 4. Then, the elastic rod 10 bends under the abutment of the support rod 11. When it is necessary for one end of the anti-loosening ring 5 to extend out of the anti-loosening ring installation groove 4, just release the lever 7. Then, the elastic rod 10 returns to its original state under its own elastic action. The restoration of the elastic rod 10 causes the first elastic rod mounting seat 8 to move upward and return to its original position. Then, the first elastic rod mounting seat 8 pushes the anti-loosening ring 5 upward to its original position, causing one end of the anti-loosening ring 5 to extend out of the anti-loosening ring installation groove 4.
