Description

Technical Field

[0001] This utility model relates to the field of spring technology, and in particular to a reinforced spring for automobiles. Background Technology

[0002] Automotive springs perform multiple core functions in the vehicle system. They absorb the vibration energy transmitted by the wheels through elastic deformation, buffer the impact from the road surface, reduce the intensity of vibration transmitted to the vehicle body, and enable the tires to quickly return to their original position after bumps, maintaining continuous contact with the ground, thus improving handling stability and braking efficiency. They are also used in many scenarios inside the vehicle, and the function of springs varies depending on their location and type.

[0003] Existing springs have relatively fixed lengths, which limits their use to specific scenarios. Furthermore, many are installed as a single unit, requiring replacement of the entire spring when maintenance is needed. Individually installed springs require tools such as electric clamps for disassembly, which is quite cumbersome. Therefore, this application provides a reinforced spring for automobiles to meet these needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a reinforced spring for automobiles to solve the problems of existing springs having a relatively fixed length, which means they can only be used in specific scenarios, and many are installed as a whole. When the spring needs maintenance or replacement, the whole spring needs to be replaced. Some individually designed springs require tools such as electric clamps to remove, which is quite troublesome.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A reinforced spring for automobiles includes a protective shell first. A threaded groove is provided in the middle of the outer wall of the protective shell first. A threaded sleeve is screwed onto the threaded groove. Mounting mechanisms are provided on both opposite sides of the threaded sleeve. A protective shell second is mounted on the top of the threaded sleeve through the mounting mechanisms. The mounting mechanisms include fixing blocks fixedly connected to the outer wall of the threaded sleeve on both opposite sides. A C-shaped frame is fixedly connected to the top of the fixing blocks, and a locking block is fixedly connected to the middle of the C-shaped frame.

[0006] Preferably, the outer wall of the second protective shell is fixedly connected with two opposing fixed buckles, and two slidable blocks are connected inside the fixed buckles. The slidable blocks are arranged vertically opposite each other inside the fixed buckles, and one end of each slidable block has an inclined surface that can abut against and fit with the buckle.

[0007] Preferably, a retaining rod is rotatably connected to one side of the C-shaped frame, and the retaining rod can be engaged with the fixing buckle.

[0008] Preferably, a shock-absorbing spring is provided inside the protective shell, the bottom of the shock-absorbing spring abuts against a first retaining cover, and the top of the shock-absorbing spring abuts against a second retaining cover.

[0009] Preferably, a plurality of limiting blocks are fixedly connected to the bottom of the protective shell, and the limiting blocks are used to restrict the movement of the cover.

[0010] Preferably, a disc is rotatably connected to the top of the second protective shell, and a fixing frame is fixedly connected to the side of the disc near the second protective shell, with one end of the fixing frame abutting against the second cover.

[0011] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, by setting up a second protective shell and a threaded sleeve, the second protective shell can be rotated first in different usage scenarios. When the second protective shell rotates, it will drive the threaded sleeve to rotate together through the mounting mechanism. When the threaded sleeve rotates, it will move downward on the threaded groove on the first protective shell, causing the second protective shell to move downward along with the threaded sleeve. When the second protective shell moves, it will drive the disc, causing the disc to move along with the second protective shell. The fixed frame will move downward along with the disc and drive the second locking cover downward. Due to the presence of the limiting block, the first locking cover at the bottom of the shock-absorbing spring will not move, so when the second locking cover moves downward, it will compress the shock-absorbing spring. When the second protective shell moves to a suitable length on the first protective shell, it can stop. After the device is placed in the usage scenario, the second protective shell can be rotated in the opposite direction to drive the threaded sleeve, allowing the device to extend outward again until both ends are in contact with the object. The advantage of this is that the overall length can be adjusted by rotating the second protective shell. In different usage scenarios, the length can be adjusted to adapt to the required usage scenario, thus expanding the range of applications.

[0012] By setting up an installation mechanism, when the shock absorber spring needs maintenance or replacement, the second protective shell can be rotated first to move the threaded sleeve downwards onto the threaded groove on the first protective shell. When the second protective shell retracts to the appropriate length, the device can be directly removed. Then, the second protective shell is rotated in the opposite direction to move the threaded sleeve to the top. At this point, the retaining rod can be rotated to disengage from the fixed buckle. Then, the second protective shell is rotated to move the fixed buckle away from the fixed block. The retaining block will then be pulled out from inside the fixed buckle and will no longer be in contact with the inclined surface on the retaining block. This allows the retaining block to no longer be limited by the retaining block, and the upper retaining block will slide downwards under the influence of gravity. When the second protective shell separates from the threaded sleeve as it rotates, the second protective shell can be directly removed from the first protective shell. After removal, the second clip, the shock-absorbing spring, and the first clip can be poured out directly from inside the first protective shell. The first and second clips are placed at the bottom and top of the new shock-absorbing spring, respectively, and then put back into the first protective shell. The second protective shell is then reconnected to the threaded sleeve through the reverse operation installation mechanism, thus completing the replacement of the shock-absorbing spring. The advantage of this method is that the entire disassembly and installation process is simple and quick, and no additional tools such as electric clamps are needed to complete the disassembly, making it convenient for workers to use.

Detailed Implementation

[0017] The present invention provides a reinforced spring for automobiles, which will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0018] like Figures 1-5 As shown, an embodiment of this utility model provides a reinforced spring for automobiles, including a protective shell 1. A threaded groove 2 is provided in the middle of the outer wall of the protective shell 1. A threaded sleeve 11 is spirally connected to the threaded groove 2. Mounting mechanisms 4 are provided on both opposite sides of the threaded sleeve 11. A second protective shell 3 is mounted on the top of the threaded sleeve 11 via the mounting mechanisms 4. The mounting mechanisms 4 include fixing blocks 41 fixedly connected to the outer wall of the threaded sleeve 11 on both opposite sides. A C-shaped frame 42 is fixedly connected to the top of the fixing blocks 41. A locking block 43 is fixedly connected to the middle of the C-shaped frame 42. Two opposing fixing buckles 5 are fixedly connected to the outer wall of the second protective shell 3. Two retaining blocks 4 are slidably connected inside the fixing buckles 5. 5. The clip 45 is arranged vertically and horizontally inside the fixed buckle 5. One end of the clip 45 has a bevel 46, which can abut and fit with the clip 43. A clip rod 44 is rotatably connected to one side of the C-shaped frame 42. The clip rod 44 can be engaged with the fixed buckle 5. A shock-absorbing spring 6 is provided inside the protective shell 1. The bottom of the shock-absorbing spring 6 abuts against the cover 7, and the top of the shock-absorbing spring 6 abuts against the cover 8. Multiple limiting blocks 12 are fixedly connected to the bottom of the protective shell 1. The limiting blocks 12 are used to limit the movement of the cover 7. A disc 9 is rotatably connected to the top of the protective shell 3. A fixed frame 10 is fixedly connected to the side of the disc 9 near the protective shell 3. One end of the fixed frame 10 abuts against the cover 8.

[0019] By setting up a second protective shell 3 and a threaded sleeve 11, in different usage scenarios, the second protective shell 3 can be rotated first. When the second protective shell 3 rotates, it will drive the threaded sleeve 11 to rotate together through the mounting mechanism 4. When the threaded sleeve 11 rotates, it will move downward on the threaded groove 2 on the first protective shell 1, causing the second protective shell 3 to move downward along with the threaded sleeve 11. When the second protective shell 3 moves, it will drive the disc 9, causing the disc 9 to move along with the second protective shell 3. The fixing frame 10 will move downward along with the disc 9 and drive the second cover 8 to move downward. Due to the limit block 12... The presence of the cover 7 at the bottom of the shock-absorbing spring 6 prevents it from moving, and the cover 8 compresses the shock-absorbing spring 6 when it moves downward. When the protective shell 3 moves to the appropriate length on the protective shell 1, it stops. After placing the device in the usage scenario, the protective shell 3 is rotated in the opposite direction to drive the threaded sleeve 11, allowing the device to extend outward again until both ends are in contact with the object. The advantage of this is that the overall length can be adjusted by rotating the protective shell 3. In different usage scenarios, the length can be adjusted to suit the required usage scenario, thus expanding the range of applications.

[0020] By setting the installation mechanism 4, when the shock absorber spring 6 needs maintenance or replacement, the second protective shell 3 can be rotated first to move the threaded sleeve 11 downward on the threaded groove 2 on the first protective shell 1. When the second protective shell 3 moves and retracts to the appropriate length, the device can be directly removed. Then, the second protective shell 3 can be rotated in the opposite direction to move the threaded sleeve 11 to the top. At this time, the lever 44 can be rotated to release the connection with the fixed buckle 5. Then, the second protective shell 3 can be rotated to move the fixed buckle 5 away from the fixed block 41. The locking block 43 will be pulled out from the inside of the fixed buckle 5 and will no longer abut against the inclined surface 46 on the locking block 45, so that the locking block 45 is no longer limited by the locking block 43. The upper locking block 45 will be affected by gravity and move downward. Slide and abut against the lower block 45. When the second protective shell 3 separates from the threaded sleeve 11 with rotation, the second protective shell 3 can be directly removed from the first protective shell 1. After removal, the second cover 8, the shock-absorbing spring 6, and the first cover 7 can be poured out directly from the inside of the first protective shell 1. After placing the first cover 7 and the second cover 8 at the bottom and top of the new shock-absorbing spring 6, put them back into the inside of the first protective shell 1. Then, the second protective shell 3 is reconnected to the threaded sleeve 11 through the reverse operation installation mechanism 4, and the replacement of the shock-absorbing spring 6 can be completed. The advantage of doing this is that the entire removal and installation process is simple and quick, and no additional tools such as electric clamps are needed to complete the disassembly, which is convenient for workers.

[0021] The technical solution provided by this utility model, by setting a second protective shell 3 and a threaded sleeve 11, allows for different usage scenarios. First, the second protective shell 3 can be rotated. When the second protective shell 3 rotates, it drives the threaded sleeve 11 to rotate along with it via the mounting mechanism 4. As the threaded sleeve 11 rotates, it moves downwards on the threaded groove 2 on the first protective shell 1, causing the second protective shell 3 to move downwards along with the threaded sleeve 11. When the second protective shell 3 moves, it drives the disc 9, causing the disc 9 to move along with the second protective shell 3. The fixing frame 10 moves downwards along with the disc 9, causing the second cover 8 to move downwards. Because... The presence of the limiting block 12 prevents the bottom cover 7 of the shock-absorbing spring 6 from moving, causing the cover 8 to press the shock-absorbing spring 6 when it moves downward. When the protective shell 3 moves to the appropriate length on the protective shell 1, it can stop. After placing the device in the usage scenario, the protective shell 3 is rotated in the opposite direction to drive the threaded sleeve 11, allowing the device to extend outward again until both ends are in contact with the object. The advantage of this is that the overall length can be adjusted by rotating the protective shell 3. In different usage scenarios, the length can be adjusted to suit the required usage scenario, thus expanding the range of applications.

[0022] By setting the installation mechanism 4, when the shock absorber spring 6 needs maintenance or replacement, the second protective shell 3 can be rotated first to move the threaded sleeve 11 downward on the threaded groove 2 on the first protective shell 1. When the second protective shell 3 moves and retracts to the appropriate length, the device can be directly removed. Then, the second protective shell 3 can be rotated in the opposite direction to move the threaded sleeve 11 to the top. At this time, the lever 44 can be rotated to release the connection with the fixed buckle 5. Then, the second protective shell 3 can be rotated to move the fixed buckle 5 away from the fixed block 41. The locking block 43 will be pulled out from the inside of the fixed buckle 5 and will no longer abut against the inclined surface 46 on the locking block 45, so that the locking block 45 is no longer limited by the locking block 43. The upper locking block 45 will be affected by gravity and move downward. Slide and abut against the lower block 45. When the second protective shell 3 separates from the threaded sleeve 11 with rotation, the second protective shell 3 can be directly removed from the first protective shell 1. After removal, the second cover 8, the shock-absorbing spring 6, and the first cover 7 can be poured out directly from the inside of the first protective shell 1. After placing the first cover 7 and the second cover 8 at the bottom and top of the new shock-absorbing spring 6, put them back into the inside of the first protective shell 1. Then, the second protective shell 3 is reconnected to the threaded sleeve 11 through the reverse operation installation mechanism 4, and the replacement of the shock-absorbing spring 6 can be completed. The advantage of doing this is that the entire removal and installation process is simple and quick, and no additional tools such as electric clamps are needed to complete the disassembly, which is convenient for workers.
