[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to Figures 1-3, an embodiment provided by the present utility model: a quickly installed automotive suspension spring, comprising a fixing ring 1. A first adjusting ring 4 is rotatably connected to the bottom end of the fixing ring 1. A fixing rod 2 is provided at the top end of the first adjusting ring 4. The outer wall of the fixing rod 2 is slidably installed on the inner wall of the fixing ring 1. A plurality of connecting rods 12 are fixedly connected to the top end of the first adjusting ring 4. The inner walls of adjacent connecting rods 12 are slidably connected to the inner wall of the fixing ring 1. A connecting ring 10 is fixedly connected to the top end of adjacent connecting rods 12. The inner wall of the connecting ring 10 is rotatably connected to the top of the inner wall of the fixing ring 1. A plurality of second springs 13 are rotatably connected to the bottom end of the connecting ring 10. The other ends of the second springs 13 are fixedly connected to the bottom end of the inner wall of the fixing ring 1. A plurality of first sliders 11 are fixedly connected to the top end of the connecting ring 10. The outer walls of adjacent first sliders 11 are arranged at the top end of the inner wall of the fixing ring 1. A plurality of clamping blocks 8 are slidably connected to the inner wall of the fixing rod 2. A first spring 9 is fixedly connected to one end of the inner side of adjacent clamping blocks 8. The other side of the first spring 9 is fixedly connected to the inner wall of the fixing rod 2. A limiting ring 3 is fixedly connected to the top end of the outer wall of the fixing rod 2 to limit the position of the fixing ring 1 to prevent it from sliding on the fixing rod 2.

[0030] Specifically, the two fixing rods 2 will be respectively installed on the vehicle frame and the lower control arm of the chassis of the vehicle. The automotive suspension spring will be fixed on the fixing rod 2, and the automotive suspension spring will be in a vertical or slightly inclined state, so as to fix the whole suspension spring on the vehicle and can shock-absorb the vehicle to improve the comfort of the occupants. When overhauling the suspension spring, the whole suspension spring body 14 will be disassembled from the fixing rod 2. Pull the first adjusting ring 4 at one end outwards, at this time the second spring 13 will be compressed. At this time, the first slider 11 will be pulled out from the groove. At this time, rotate the first adjusting ring 4, thereby driving the first slider 11 to move towards the position of the clamping block 8 and intersect on a straight line. At this time, push inwards, the first slider 11 will squeeze the inclined surface of the clamping block 8 to force the clamping block 8 to move downwards and withdraw from the fixing ring 1, so that the fixing rod 2 loses the restriction on the fixing ring 1. Take out the first adjusting ring 4 in the same way on the other side. At this time, the whole suspension spring body 14 will be disassembled.

[0031] Refer to Figures 4-6, the suspension spring body 14, the fixing rings 1 are respectively arranged on the left and right sides of the suspension spring body 14 at opposite ends. A first protective cover 5 is arranged at the left end of the suspension spring body 14, and a second protective cover 6 is arranged at the right end of the suspension spring body 14. A plurality of second chutes 17 are opened at the left end of the inner wall of the second protective cover 6. Second sliders 15 are arranged on the inner walls of adjacent second chutes 17. The second sliders 15 are all opened at the right end of the outer wall of the first protective cover 5. The left ends of the inner walls of the second protective covers 6 are all rotatably connected with buckles 18. One ends of the outer walls of the buckles 18 are all fixedly connected with tension springs 19. The other ends of the tension springs 19 are all fixedly connected to the inner walls of the second protective covers 6. Push blocks 20 are arranged at the tops on the same side of the outer walls of the buckles 18 and the tension springs 19. One ends of the outer sides of adjacent push blocks 20 are all slidably connected to the inner walls of the second protective covers 6. The common connection of the outer ends of adjacent second protective covers 6 is provided with a second adjusting ring 7. The inner walls of the second adjusting rings 7 are all rotatably connected to the outer walls of the second protective covers 6. A plurality of first chutes 16 are opened in the inner walls of the second protective covers 6. The sizes of the first chutes 16 and the second chutes 17 are both in conformity with the diameter size of the second slider 15.

[0032] Specifically, for the installation of the protective cover, align the second slider 15 on the first protective cover 5 with the second chute 17 and compress it downward. At this time, the second slider 15 will move downward along the groove of the second chute 17. After a period of time, it will squeeze the buckle 18 and stretch the tension spring 19. The squeezing of the buckle 18 will open the channel between the second chute 17 and the first chute 16 so that the second slider 15 can move onto the first chute 16. At this time, release the first protective cover 5. At this time, the first protective cover 5 will move upward under the reaction force of the suspension spring body 14 and disengage from the buckle 18. At this time, the buckle 18 will be pulled back to its original position by the reaction force of the tension spring 19 to block the channel between the second chute 17 and the first chute 16. At this time, the installation of the first protective cover 5 and the second protective cover 6 is completed.

[0033] Working principle: The fixing ring 1 is sleeved along the outer wall of the fixing rod 2. Thus, during the sliding process, the fixing ring 1 will squeeze the clamping block 8 downward and compress the first spring 9. When the fixing ring 1 contacts the limiting ring 3, the clamping block 8 will move upward under the reaction force of the first spring 9 and snap into the fixing ring 1 to restrict the movement of the fixing ring 1. Thus, under the action of the clamping block 8 and the limiting ring 3, the entire suspension spring body 14 is fixed on the fixing rod 2. For the disassembly between the first protective cover 5 and the second protective cover 6, rotate the second adjusting ring 7. The second adjusting ring 7 will drive the push block 20 to rotate, thereby moving the buckle 18 outward and opening the channel between the first chute 16 and the second chute 17. Then, compress the suspension spring body 14. The second slider 15 on the first protective cover 5 moves downward and enters the second chute 17 through the first chute 16 under the action of the buckle 18. Then, cancel the compression of the suspension spring body 14, which will cause the first protective cover 5 to disengage from the second protective cover 6 along the second chute 17, thereby exposing the suspension spring body 14. Then, perform maintenance on the suspension spring body 14.

[0034] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
