However, this will make it difficult to disassemble and assemble the buffer block. When the buffer block is severely worn, it is easy to cause the limiting effect of the buffer block on the suspension spring to decline, increasing the probability of over-compression of the suspension spring and reducing the service life of the suspension spring.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] 1. When the main body of the suspension spring is compressed to a certain extent, the main body of the spring buffer will drive the two fixed seats to approach each other, thereby driving the four main bodies of the buffer blocks to approach each other. The two fixed seats are prevented from approaching further by the main bodies of the buffer blocks, so that the main body of the suspension spring can be prevented from being over-compressed. When the main bodies of the buffer blocks are severely worn and need to be replaced, rotate the bolt to make the movable block lose its limit, slide the movable block out of the slide rail, separate the movable block, so that the fixed ring is separated, and then the main bodies of the buffer blocks are separated, so that the main bodies of the buffer blocks can be removed.

Thus, the device is convenient for disassembling and assembling the main bodies of the buffer blocks, and it is convenient to quickly replace the main bodies of the buffer blocks after wear, thereby reducing the probability of over-compression of the main body of the suspension spring, and thus improving the service life of the main body of the suspension spring;
[0017] 2. When it is necessary to fix the movable block and the slide rail by bolts, move the push plate to drive the connection shaft to move, so that the connection shaft disengages from the baffle plate, move the baffle plate upward, pass the bolt through the baffle plate and the positioning plate. At this time, the bolt can pass through the movable block and the slide rail to fix the movable block and the slide rail together. Move the baffle plate downward so that the baffle plate enters the interior of the positioning plate, release the push plate, and push the connection shaft to move in the reverse direction by the connection spring, so that the connection shaft enters the interior of the baffle plate, and block the bolt by the baffle plate, so that the bolt cannot move, so that the bolt cannot disengage from the movable block and the slide rail, thereby improving the stability of the placement of the main body of the buffer block. And when replacing the bolt, only need to move the push plate and the baffle plate, so that it will not affect the disassembly and assembly efficiency of the bolt, and thus will not affect the disassembly and assembly efficiency of the main body of the buffer block. Therefore, the device is convenient for improving the stability of the placement of the main body of the buffer block without affecting the disassembly and assembly efficiency of the main body of the buffer block, thereby improving the protection effect of the main body of the buffer block on the main body of the suspension spring, and further improving the service life of the main body of the suspension spring.

[0026] Embodiment 1
[0027] As Figures 1-4 shown;
[0028] A protective buffer block for an automotive suspension spring, including a spring buffer main body.
[0029] To solve the existing problems in the prior art as disclosed in the background art above, "When the existing suspension spring buffer block is in use, the buffer block is usually installed inside the spring buffer to limit the maximum compression amount of the suspension spring through the buffer block and prevent excessive compression. However, this will cause difficulties in disassembling and assembling the buffer block. When the buffer block is severely worn, it is easy to cause the limiting effect of the buffer block on the suspension spring to decline, increasing the probability of excessive compression of the suspension spring and reducing the service life of the suspension spring." In combination, this problem is obviously an existing and difficult-to-solve problem. In view of this, to solve this technical problem, a slide rail and a movable block are added to this application document;
[0030] Furthermore:
[0031] As Figures 1 to 4 shown:
[0032] Combined with the above content: A protective buffer block for an automotive suspension spring, comprising a spring buffer main body 1. Fixed seats 2 are provided at both ends of the spring buffer main body 1. A suspension spring main body 3 is fixedly arranged between the two fixed seats 2. Two slide rails 4 are fixedly arranged on one side of each of the two fixed seats 2. Moving blocks 5 are arranged inside the four slide rails 4. Fixed rings 6 are fixedly arranged on the sides of the four moving blocks 5. Buffer block main bodies 7 are fixedly arranged on the sides of the four fixed rings 6. Two limit blocks 8 are fixedly arranged on one side of each of the two fixed rings 6. Two limit slots are respectively formed inside the other two fixed rings 6. The inner parts of the four limit slots are respectively in fit with the sides of the four limit blocks 8. Bolts 9 are arranged inside the four moving blocks 5. The sides of the four bolts 9 are respectively in threaded connection with the interiors of the four slide rails 4.
[0033] In this implementation: The impact caused by the uneven road surface is absorbed by the suspension spring main body 3, and the impact force absorbed by the suspension spring main body 3 is buffered by the spring buffer main body 1. When the suspension spring main body 3 is compressed to a certain extent, the spring buffer main body 1 will drive the two fixed seats 2 to approach each other, thereby driving the four moving blocks 5 to approach each other, thereby driving the four fixed rings 6 to approach each other, thereby driving the four buffer block main bodies 7 to approach each other. Part of the impact force received by the spring buffer main body 1 is buffered by the buffer block main bodies 7. At the same time, the continuous approach of the two fixed seats 2 can be blocked, thereby preventing the over-compression of the suspension spring main body 3. When the buffer block main bodies 7 are severely worn and need to be replaced, rotate the bolts 9 to make the moving blocks 5 lose their limits, slide the moving blocks 5 out of the slide rails 4. At this time, the moving blocks 5 lose their limits and are separated, thereby separating the fixed rings 6, thereby separating the buffer block main bodies 7, so that the buffer block main bodies 7 can be removed. Replace the new buffer block main bodies 7, fit the fixed rings 6 together, so that the limit blocks 8 enter the interiors of the limit slots, thereby making the buffer block main bodies 7 fit together. Slide the moving blocks 5 into the interiors of the slide rails 4, and fix the slide rails 4 and the moving blocks 5 together through the bolts 9, thereby limiting the fixed rings 6 and the buffer block main bodies 7, completing the disassembly and assembly of the buffer block main bodies 7, so that the buffer block main bodies 7 of this device are convenient for disassembly and assembly, and it is convenient to quickly replace the buffer block main bodies 7 after wear, thereby reducing the probability of over-compression of the suspension spring main body 3, thereby increasing the service life of the suspension spring main body 3.
[0034] In an alternative embodiment: The bottom end of one of the fixed seats 2 is fixedly connected to the fixed end of the spring buffer main body 1, and the top end of the other fixed seat 2 is fixedly connected to the telescopic end of the spring buffer main body 1.

[0036] In an alternative embodiment: On one side of each of the four slide rails 4, two positioning plates 10 are fixedly provided, and positioning grooves are formed on one side of each of the eight positioning plates 10.
[0037] In this embodiment: The positioning plates 10 facilitate the limitation of the baffle plates 11.
[0038] In an alternative embodiment: On one side of each of the four slide rails 4, baffle plates 11 are provided, and the sides of the four baffle plates 11 are respectively fitted with the interiors of the eight positioning grooves.
[0039] In this embodiment: The baffle plates 11 facilitate preventing the bolts 9 from moving.
[0040] In an alternative embodiment: On one side of each of the four slide rails 4, limit tubes 12 are provided, and the sides of the four limit tubes 12 are respectively fixedly connected to one side of the eight positioning plates 10.
[0041] In this embodiment: The limit tubes 12 facilitate the limitation of the connecting shafts 13.
[0042] In an alternative embodiment: Connecting grooves are formed inside each of the four limit tubes 12, and connecting shafts 13 are provided inside the four connecting grooves.
[0043] In this embodiment: The connecting shafts 13 facilitate the limitation of the baffle plates 11.
[0044] In an alternative embodiment: Connecting holes are formed inside each of the four baffle plates 11, the interiors of the four connecting holes are respectively fitted with the sides of the four connecting shafts 13, and handles 16 are fixedly provided at the tops of the four baffle plates 11.
[0045] In this embodiment: The handles 16 facilitate moving the baffle plates 11.
[0046] In an alternative embodiment: On one side of each of the four connecting shafts 13, connecting springs 14 are fixedly provided, the sides of the four connecting springs 14 are respectively fixedly connected to the interiors of the four limit tubes 12, and push plates 15 are fixedly provided on the sides of the four connecting springs 14.
[0047] In this embodiment: The push plates 15 facilitate moving the connecting shafts 13.
[0048] The working principle and usage process of the present utility model are as follows: The impact caused by uneven road surfaces is absorbed by the suspension spring body 3, and the impact force absorbed by the suspension spring body 3 is buffered by the spring buffer body 1. When the suspension spring body 3 is compressed to a certain extent, the spring buffer body 1 will drive the two fixed seats 2 to approach each other, thereby driving the four movable blocks 5 to approach each other, thereby driving the four fixed rings 6 to approach each other, thereby driving the four buffer block bodies 7 to approach each other. Part of the impact force received by the spring buffer body 1 is buffered by the buffer block body 7, and at the same time, the continued approach of the two fixed seats 2 can be prevented, thereby preventing the over-compression of the suspension spring body 3. When the buffer block body 7 is severely worn and needs to be replaced, rotate the bolt 9 to make the movable block 5 lose its limit, slide the movable block 5 out of the slide rail 4. At this time, the movable block 5 loses its limit and is separated, so that the fixed ring 6 is separated, so that the buffer block body 7 is separated, and the buffer block body 7 can be removed. Replace the new buffer block body 7, fit the fixed rings 6 together, so that the limiting block 8 enters the inside of the limiting groove, so that the buffer block bodies 7 are fitted together, slide the movable block 5 into the inside of the slide rail 4, and fix the slide rail 4 and the movable block 5 together through the bolt 9, so that the fixed ring 6 and the buffer block body 7 are limited, completing the disassembly and assembly of the buffer block body 7, so that the device is convenient for disassembling and assembling the buffer block body 7, making it convenient to quickly replace the buffer block body 7 after wear, thereby reducing the probability of over-compression of the suspension spring body 3, thereby increasing the service life of the suspension spring body 3. When it is necessary to fix the movable block 5 and the slide rail 4 through the bolt 9, move the push plate 15, thereby driving the connecting shaft 13 to move, so that the connecting shaft 13 disengages from the baffle 11, so that the baffle 11 loses its limit, move the baffle 11 upward, and pass the bolt 9 through the baffle 11 and the positioning plate 10. At this time, the bolt 9 can pass through the movable block 5 and the slide rail 4 to fix the movable block 5 and the slide rail 4 together. After the bolt 9 is fixed, move the baffle 11 downward so that the baffle 11 enters the inside of the positioning plate 10, release the push plate 15, and push the connecting shaft 13 to move in the reverse direction through the connecting spring 14, so that the connecting shaft 13 enters the inside of the baffle 11, and the bolt 9 is blocked by the baffle 11, so that the bolt 9 cannot move, so that the bolt 9 cannot disengage from the movable block 5 and the slide rail 4, thereby increasing the stability when the movable block 5 and the slide rail 4 are fixed, thereby increasing the stability when the fixed ring 6 and the buffer block body 7 are placed. And when the bolt 9 is replaced, only the push plate 15 and the baffle 11 need to be moved, so that the disassembly and assembly efficiency of the bolt 9 will not be affected, so that the disassembly and assembly efficiency of the buffer block body 7 will not be affected, so that the device is convenient to improve the stability when the buffer block body 7 is placed without affecting the disassembly and assembly efficiency of the buffer block body 7, thereby increasing the protection effect of the buffer block body 7 on the suspension spring body 3, thereby further increasing the service life of the suspension spring body 3.
