Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, and in particular to a shock absorber that is easy to install. Background Technology

[0002] In motorcycle production, shock absorbers play a crucial role, effectively absorbing and dispersing impact forces to protect the vehicle and its occupants. In practical applications, an easy-to-install shock absorber typically requires the following technologies:

[0003] 1. Shock Absorption Mechanism: The shock absorption mechanism adopts methods such as spring shock absorption, hydraulic shock absorption or air shock absorption to effectively buffer the impact force. For example, spring shock absorption stores and releases energy through the elastic deformation of the spring to reduce the impact force. Hydraulic shock absorption uses the flow of liquid in the damping orifice to generate damping force and consume impact energy. Air shock absorption relies on the compressibility of compressed air to achieve buffering.

[0004] 2. Connection mechanism: The shock absorber is securely installed on the corresponding equipment or structure by means of bolt connection, welding, clamp connection, etc. Bolt connection makes it easy to disassemble and replace the shock absorber. Welded connection can provide a high-strength connection, but it is relatively difficult to repair and replace later. Clamp connection is suitable for some scenarios with high requirements for installation speed. It is easy to install and can ensure a certain connection strength.

[0005] Existing Chinese patent: A motorcycle shock absorber with good cushioning performance, publication number: CN217328256U, includes a cylinder tube, a tie rod, a base, a connecting plate, a shock-absorbing assembly, and an auxiliary assembly. The tie rod is slidably disposed in the cylinder tube, the base is disposed at the bottom of the cylinder tube, the connecting plate is disposed on the tie rod, the shock-absorbing assembly is disposed on the connecting plate, and the auxiliary assembly is disposed between the base and the shock-absorbing assembly. The shock-absorbing assembly includes a base plate, a steel wire rope, and a top plate. The base plate is disposed on the connecting plate, the steel wire rope is wound and passed through the base plate, and the top plate is sleeved on the steel wire rope. This utility model relates to the field of motorcycle shock absorber design, specifically to a motorcycle shock absorber with good cushioning performance.

[0006] However, during the implementation of the above technical solution, at least the following technical problems were found: When installing the above shock absorber, the tire and frame need to be completely removed before the connecting parts can be put on the bolts. The operation is cumbersome, time-consuming, labor-intensive and inconvenient. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a shock absorber that is easy to install, solving the technical problem that the aforementioned shock absorbers require the complete removal of the tires and frame before the connecting parts can be fitted onto the bolts for installation, which is cumbersome, time-consuming, labor-intensive, and inconvenient.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A shock absorber that is easy to install includes a damping cylinder, a damping rod mounted on the damping cylinder, mounting seats threaded onto both the damping cylinder and the damping rod, a spring installed between the two mounting seats, a U-shaped fork provided on the side end of the mounting seat, a threaded rod fixedly mounted on the U-shaped fork, a threaded sleeve rotatably mounted on the mounting seat, a U-shaped clip rotatably mounted on the U-shaped fork, and the threaded rod and the threaded sleeve being threadedly connected.

[0010] Preferably, the mounting base is symmetrically provided with sliding sleeves, and the U-shaped fork is symmetrically fixedly installed with limit rods.

[0011] Preferred configuration: The limiting rod and the sliding sleeve are slidably connected.

[0012] Preferably, the U-shaped fork has a first fixing hole symmetrically provided, and the U-shaped clip has a second fixing hole symmetrically provided.

[0013] Preferably, a knob is fixedly installed on the threaded sleeve.

[0014] Preferred: A card plate is fixedly installed on the U-shaped card.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. During installation, align the openings of the two U-shaped forks with the bolts at the mounting positions, then turn the knob. The knob will rotate the threaded sleeve. Since the threaded sleeve is threadedly connected to the threaded rod, the threaded sleeve will push the threaded rod to rotate. Turning the knob will cause the threaded rod to push the U-shaped fork outward, allowing it to lock onto the bolt through the opening at the side end of the U-shaped fork. Then, turn the retaining plate to rotate the U-shaped clip 180 degrees. After the U-shaped clip rotates, the first and second fixing holes will align. Once the first and second fixing holes are aligned, the U-shaped clip can be fixed in position by inserting screws or pins. Installation can be completed without disassembling the tires and frame, achieving a convenient installation effect.

[0017] 2. The damping cylinder and damping rod are assembled with the mounting base by means of threaded connection. When the damping cylinder needs maintenance, it can be quickly unscrewed for disassembly. Attached Figure Description

[0024] This application provides a conveniently installed shock absorber, effectively solving the technical problem of the aforementioned shock absorbers, which require complete removal of the tires and frame before installing the connecting parts onto the bolts, making the operation cumbersome, time-consuming, labor-intensive, and inconvenient. During installation, the openings of the two U-shaped forks are aligned with the bolts at the installation positions, and then the knob is turned. The knob will cause the threaded sleeve to rotate. Since the threaded sleeve is threadedly connected to the threaded rod, the threaded sleeve will push the threaded rod to rotate. Turning the knob causes the threaded rod to push the U-shaped fork... Slide the fork outwards to engage with the bolt through the opening at the side of the U-shaped fork. Then rotate the retaining plate to rotate the U-shaped clip 180 degrees. After the U-shaped clip rotates, the first and second fixing holes will align. Once the first and second fixing holes are aligned, the U-shaped clip can be fixed in position by inserting screws or pins. Installation can be completed without disassembling the tires and frame, achieving a convenient installation effect. The damping cylinder and damping rod are assembled with the mounting base by threaded connection. When the damping cylinder needs maintenance, it can be quickly unscrewed for disassembly.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that the shock absorber requires complete removal of the tire and frame before installation, and the connecting parts must be fitted onto the bolts. This process is cumbersome, time-consuming, labor-intensive, and inconvenient. The overall approach is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a buffer shock absorber that is easy to install, including a damping cylinder 1, a damping rod 2 installed on the damping cylinder 1, a mounting seat 3 threadedly installed on both the damping cylinder 1 and the damping rod 2, a spring 4 installed between the two mounting seats 3, and a U-shaped fork 5 provided on the side end of the mounting seat 3.

[0028] A threaded rod 6 is fixedly installed on the U-shaped fork 5, a threaded sleeve 7 is rotatably installed on the mounting base 3, a U-shaped clip 8 is rotatably installed on the U-shaped fork 5, the threaded rod 6 and the threaded sleeve 7 are threadedly connected, a sliding sleeve 9 is symmetrically arranged on the mounting base 3, and a limit rod 11 is symmetrically fixedly installed on the U-shaped fork 5.

[0029] The limiting rod 11 and the sliding sleeve 9 are slidably connected. The U-shaped fork 5 is symmetrically provided with the first fixing hole 12, and the U-shaped clip 8 is symmetrically provided with the second fixing hole 13. The threaded sleeve 7 is fixedly installed with the knob 14, and the U-shaped clip 8 is fixedly installed with the clip plate 15.

[0030] Damping cylinder 1: It is a key component of the shock absorber. It is usually filled with damping medium. It works with damping rod 2 to consume impact energy through damping and achieve shock absorption. It is connected to mounting base 3 by threads for easy disassembly during maintenance.

[0031] Damping rod 2: It works in conjunction with damping cylinder 1 and reciprocates within damping cylinder 1 when impacted. It generates damping force through the damping medium within damping cylinder 1 to reduce the impact. It is also connected to mounting base 3 via threads for easy maintenance and disassembly.

[0032] Mounting seat 3: threaded onto damping cylinder 1 and damping rod 2, connecting the main body of the shock absorber to the external mounting components. The side U-shaped fork 5 and related structures enable convenient installation. The sliding sleeve 9 on the mounting seat 3 cooperates with the upper limit rod 11 of the U-shaped fork 5 to restrict the movement of the U-shaped fork 5 and ensure smooth installation.

[0033] Spring 4: Placed between the two mounting bases 3, it absorbs and releases energy through its own elastic deformation, assisting the damping effect of damping cylinder 1 and damping rod 2, and enhancing the buffering and shock absorption capacity;

[0034] U-shaped fork 5: Fixed on the side of the mounting base 3, with an opening for aligning with the mounting bolt. It is pushed by the threaded rod 6 to lock onto the bolt, achieving initial connection with the mounting part. Its upper limit rod 11 is slidably connected to the sliding sleeve 9 of the mounting base 3 to prevent the U-shaped fork 5 from rotating when the threaded sleeve 7 rotates, ensuring smooth sliding. The first fixing hole 12 on the U-shaped fork 5 and the second fixing hole 13 on the U-shaped clip 8 cooperate to fix the position of the U-shaped clip 8.

[0035] Threaded rod 6: Fixed to U-shaped fork 5, threadedly connected to threaded sleeve 7. When threaded sleeve 7 rotates, threaded rod 6 pushes U-shaped fork 5 outward, so that U-shaped fork 5 is locked on the mounting bolt, thus completing the initial fixing of the buffer shock absorber to the mounting position.

[0036] Threaded sleeve 7: Rotatably mounted on mounting base 3, and through threaded engagement with threaded rod 6, converts the rotational motion of knob 14 into linear motion of threaded rod 6, pushing U-shaped fork 5 to slide, thus achieving convenient installation;

[0037] U-shaped clip 8: Rotatably mounted on U-shaped fork 5. After rotating 180 degrees, its second fixing hole 13 is aligned with the first fixing hole 12 of U-shaped fork 5. Screws or pins are inserted to further fix the U-shaped fork 5 to the bolt connection of the mounting position, thereby enhancing the stability of the installation.

[0038] Sliding sleeve 9: Symmetrically arranged on the mounting base 3, it is slidably connected to the upper limit rod 11 of the U-shaped fork 5. When the threaded sleeve 7 rotates, it limits the U-shaped fork 5 to prevent it from rotating with the threaded sleeve 7, ensuring that the U-shaped fork 5 slides smoothly along the axial direction of the threaded rod 6, which is conducive to installation.

[0039] Limiting rod 11: Symmetrically fixed to U-shaped fork 5, and slidably connected to mounting base 3 sliding sleeve 9. During installation, it restricts the movement of U-shaped fork 5, so that it can only slide along the axial direction of threaded rod 6, preventing unnecessary rotation due to rotation of threaded sleeve 7, and ensuring smooth installation.

[0040] First fixing hole 12: Symmetrically opened on U-shaped fork 5, and aligned with second fixing hole 13 after U-shaped clip 8 is rotated 180 degrees, screws or pins are inserted to achieve fixed connection between U-shaped clip 8 and U-shaped fork 5, and to stabilize the connection between the buffer shock absorber and the mounting bolt.

[0041] The second fixing hole 13 is symmetrically opened on the U-shaped clip 8. After rotating 180 degrees, it is aligned with the first fixing hole 12 of the U-shaped fork 5, which makes it convenient to insert screws or pins to fix the U-shaped clip 8 to the U-shaped fork 5 and enhance the installation of the shock absorber.

[0042] Knob 14: Fixed on the threaded sleeve 7, providing an application point for the operator to easily rotate the threaded sleeve 7, and push the U-shaped fork 5 to slide through the threaded rod 6, simplifying the installation operation and making the installation more convenient;

[0043] Carbomer 15: Fixed on the U-shaped clip 8, allowing the operator to rotate the U-shaped clip 8 180 degrees to align the first fixing hole 12 with the second fixing hole 13, facilitating fixed connection and serving as a convenient installation auxiliary component.

[0044] Working principle:

[0045] During installation, align the openings of the two U-shaped forks 5 with the bolts at the mounting positions, and then turn the knob 14. The knob 14 will rotate the threaded sleeve 7. Since the threaded sleeve 7 is threadedly connected to the threaded rod 6, the threaded sleeve 7 will push the threaded rod 6 to rotate. Turning the knob 14 will cause the threaded rod 6 to push the U-shaped fork 5 outward, so that it can be locked onto the bolt through the opening at the side end of the U-shaped fork 5. Then, turn the retaining plate 15 to rotate the U-shaped clip 8 180 degrees. After the U-shaped clip 8 rotates, the first fixing hole 12 and the second fixing hole 13 will be aligned. After the first fixing hole 12 and the second fixing hole 13 are aligned, the position of the U-shaped clip 8 can be fixed by inserting screws or pins. The installation can be completed without disassembling the tires and the frame, achieving the effect of easy installation. When the threaded sleeve 7 rotates, the limiting rod 11 on the U-shaped fork 5 will be limited by the sliding sleeve 9, which can prevent the U-shaped fork 5 from rotating with the threaded sleeve 7, so that it can slide smoothly.

[0046] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
