Description

Technical Field

[0001] This utility model relates to the field of wheel noise reduction ring technology, and in particular to a steel sleeve and steel core structure for assembling wheel noise reduction rings. Background Technology

[0002] To improve the assembly stability and operational reliability of muffler rings, a steel sleeve and steel core structure for their installation is proposed. This structure consists of an outer steel sleeve and an inner steel core, possessing good mechanical strength, thermal stability, and assembly adaptability. It can provide sufficient clamping force and limiting effect while ensuring assembly accuracy, thereby achieving reliable fixation of the muffler ring on the wheel. In addition, this steel sleeve and steel core structure can also be used in conjunction with damping pads, buffer layers, etc., to effectively enhance the vibration reduction performance and service life of the system while ensuring assembly strength.

[0003] In practical applications, existing steel-sleeve-steel-core structural components are usually connected to the muffler ring in a fixed manner. Although this structure has a certain degree of stability, it is inconvenient to operate during assembly and disassembly. Once assembled, it is difficult to quickly disassemble or replace the muffler ring. Especially during maintenance or replacement, tools or destructive removal are required, which affects work efficiency, increases maintenance costs, and is not conducive to batch operations and subsequent maintenance.

[0004] Therefore, the existing steel sleeve and steel core structural components, which mostly use fixed fit and connection with the muffler ring, are cumbersome to install and disassemble, requiring tools or even destructive removal, which affects replacement efficiency and maintenance convenience, increases maintenance costs, and is not conducive to batch assembly and later maintenance. There is an urgent need to design a new type of steel sleeve and steel core structural component for wheel muffler ring assembly. Utility Model Content

[0005] To overcome the problem that existing steel sleeve and steel core structural components mostly use fixed fit and sound-absorbing ring connection, although they are stable, the assembly and disassembly operations are cumbersome, requiring tools or even destructive removal, which affects the replacement efficiency and maintenance convenience, increases maintenance costs, and is not conducive to batch assembly and later maintenance.

[0006] The technical solution of this utility model is as follows: a steel sleeve and steel core structural component for assembling a wheel muffler ring, comprising a muffler ring body and a steel sleeve body mounted on the muffler ring body. The steel sleeve body has several fitting grooves inside, with elastic elements connected inside each groove. A locking block is connected to the elastic element near the center of the steel sleeve body. A movable groove is provided at the right end of the steel sleeve body, with a small spring connected inside. A sliding plate is connected to the other end of the small spring, and the sliding plate is slidably connected to the movable groove. A dial ring is connected to the end of the sliding plate away from the small spring. A pressing plate, L-shaped, is connected to the pressing plate near the center of the steel sleeve body and is movably connected to the elastic element. A sleeve is movably connected inside the steel sleeve body, fitting onto the muffler ring body. A locking groove is provided at the outer end of the sleeve. When the sleeve is inserted into the steel sleeve body, it presses the elastic element until the locking block fits into the locking groove. When the sleeve needs to be removed from the steel sleeve body, the dial ring is pushed, causing the sliding plate to press the small spring, thus releasing the locking block from the locking groove.

[0007] Preferably, an efficient quick-installation and quick-disassembly connection mechanism is constructed by setting up an elastic element and a locking block. In use, the sleeve is first fitted onto one end of the muffler ring body, and then the entire assembly is inserted into the steel sleeve body. During insertion, the sleeve compresses the elastic element, causing the locking block to automatically engage in the slot, quickly completing a secure connection. For disassembly, simply push the dial ring; the dial ring drives the sliding plate to compress the small spring, causing the compression plate to press the elastic element inward, causing the locking block to disengage from the slot. Then, pulling out the muffler ring body allows the sleeve to be pulled out as well, achieving a quick installation and disassembly effect and improving maintenance efficiency.

[0008] Preferably, a connecting cylinder is connected to the left end of the steel sleeve body, and a square hole is opened on the right side of the inside of the connecting cylinder.

[0009] Preferably, a large spring is connected to the left end of the steel sleeve body, and a movable ring is connected to the end of the large spring away from the steel sleeve body. The movable ring is slidably connected to the connecting cylinder.

[0010] Preferably, the connecting cylinder has several locking holes on the left side inside, with ball bearings movably connected inside the locking holes. A steel core body is movably connected inside the connecting cylinder, and a square plate is connected to the right end of the steel core body. The square plate matches the square holes.

[0011] Preferably, a limiting groove is provided on the left side of the outer end of the steel core body, and the limiting groove is movably connected to the ball bearing.

[0012] Preferably, the moving ring moves towards the steel sleeve body to compress the large spring, and then the steel core body is inserted into the connecting cylinder and the square plate is aligned with the square hole.

[0013] Preferably, the large spring drives the moving ring to reset, causing the moving ring to squeeze the ball in the card hole, so that the protruding part of the ball fits into the limiting groove.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up elastic components and other linkage mechanisms such as locking blocks, the steel sleeve and steel core structure is optimized, which significantly improves the efficiency of assembly and disassembly, effectively shortens the maintenance and replacement cycle, and its structure is stable and reliable, avoiding component wear and loosening of connections caused by frequent disassembly and assembly. It not only reduces the dependence on tools, but also effectively improves the convenience of on-site operations. It is especially suitable for use scenarios that require frequent replacement or maintenance, and enhances the overall practicality and reliability while improving the efficiency of equipment operation and maintenance.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment: a steel sleeve and steel core structural component for assembling a wheel muffler ring, including a muffler ring body 1; and a steel sleeve body 2 installed on the muffler ring body 1. The steel sleeve body 2 has several fitting grooves 21 inside, and elastic elements 22 are connected inside the fitting grooves 21. A locking block 23 is connected to the elastic element 22 near the center of the steel sleeve body 2. A movable groove 24 is provided at the right end of the steel sleeve body 2, and a small spring 25 is connected inside the movable groove 24. A sliding plate 26 is connected to the other end of the small spring 25, and the sliding plate 26 is slidably connected to the movable groove 24. A deflector ring 27 is connected to the end of the sliding plate 26 away from the small spring 25. A pressing plate 28 is connected to the sliding plate 26 near the center of the steel sleeve body 2. The pressing plate 28 is L-shaped and movably connected to the elastic element 22. A sleeve 29 is movably connected inside the steel sleeve body 2, and the sleeve 29 is sleeved with the muffler ring body 1. A locking groove 210 is provided at the outer end of the sleeve 29. When the sleeve 29 is inserted into the steel sleeve body 2, the sleeve 29 compresses the elastic element 22 until the locking block 23 fits into the locking groove 210. When the sleeve 29 needs to be removed from the steel sleeve body 2, the push ring 27 drives the slide plate 26 to compress the small spring 25, causing the compression plate 28 to compress the elastic element 22 and release the locking block 23 from the locking groove 210. By setting the elastic element 22 and the locking block 23, an efficient quick-installation and quick-disassembly connection mechanism is constructed. In use, the sleeve 29 is first sleeved onto one end of the muffler ring body 1. Then, the entire sleeve 29 is inserted into the steel sleeve body 2. During the insertion process, the sleeve 29 squeezes the elastic element 22, causing the locking block 23 to automatically embed into the locking groove 210, quickly completing a stable connection. When disassembling, simply push the dial ring 27. The dial ring 27 drives the slide plate 26 to compress the small spring 25, causing the squeezing plate 28 to squeeze the elastic element 22 inward, causing the locking block 23 to disengage from the locking groove 210. Then, pull out the muffler ring body 1 to pull out the sleeve 29 together, achieving the effect of quick disassembly and assembly, thereby improving maintenance efficiency.

[0025] Please see Figures 1-6In this embodiment, a connecting cylinder 31 is connected to the left end of the steel sleeve body 2. A square hole 32 is provided on the right side of the inside of the connecting cylinder 31. A large spring 33 is connected to the left end of the steel sleeve body 2. A moving ring 34 is connected to the end of the large spring 33 away from the steel sleeve body 2. The moving ring 34 is slidably connected to the connecting cylinder 31. Several locking holes 35 are provided on the left side of the inside of the connecting cylinder 31. A ball bearing 36 is movably connected inside the locking holes 35. A steel core body 37 is movably connected inside the connecting cylinder 31. A square plate 38 is connected to the right end of the steel core body 37. The square plate 38 matches the square hole 32. By setting the matching relationship between the square plate 38 and the square hole 32, the rotation angle of the steel core body 37 after being inserted into the connecting cylinder 31 is limited and the assembly direction is accurate. Compared with the traditional circular insertion structure, the problem of rotational misalignment or directional interference is avoided. The square structure matching has good positioning guidance and is particularly suitable for connection scenarios that require maintaining directional consistency. It also provides an accurate initial state for the subsequent locking structure, which helps to improve the overall connection stability and structural integrity.

[0026] Please see Figures 2-6 In this embodiment, a limiting groove 39 is formed on the left side of the outer end of the steel core body 37. The limiting groove 39 is movably connected to the ball 36. The moving ring 34 moves towards the steel sleeve body 2 to compress the large spring 33. Then, the steel core body 37 is inserted into the connecting cylinder 31 and the square plate 38 is aligned with the square hole 32. The large spring 33 drives the moving ring 34 to reset, causing the moving ring 34 to squeeze the ball 36 in the retaining hole 35, so that the protruding part of the ball 36 fits against the limiting groove 39. Through the reset action of the large spring 33, the ball 36 is controlled by the moving ring 34 and can move... When the moving ring 34 is in the reset state, the ball 36 is automatically embedded into the limiting groove 39 of the steel core body 37, realizing quick engagement and locking. The position of the limiting groove 39 is precisely set on the outer circumferential side of the steel core body 37, corresponding to the position of the ball 36. Combined with the elastic mechanism, it forms a resettable and unlockable state switching structure. Compared with the traditional threaded locking method, the engagement of the ball 36 is not only fast and easy to operate, but also can achieve multi-point uniform engagement, improving the locking strength and connection reliability. This structural design is compact and is particularly suitable for industrial application scenarios where space is limited or frequent disassembly and assembly are required.

[0027] During assembly, first, sleeve 29 is fitted onto one end of the muffler ring body 1, and then the entire assembly is inserted into the steel sleeve body 2. During insertion, the groove 210 at the outer end of sleeve 29 gradually presses against the elastic element 22 in the adapter groove 21 inside the steel sleeve body 2. This causes the locking block 23 on the elastic element 22 to automatically engage with the groove 210 under the action of elastic restoring force, achieving stable positioning and initial locking. When disassembly is required, simply push the dial ring 27. The dial ring 27 drives the slide plate 26 to slide and compress the small spring 25, which in turn pushes the L-shaped compression plate 28 connected to one end of the slide plate 26 inward, compressing the elastic element 22 and causing the locking block 23 to retract. By freeing itself from the slot 210, the muffler ring body 1 and sleeve 29 can be easily pulled out, enabling quick disassembly. At the same time, the steel core body 37 is sleeved with the other end of the muffler ring, and the square plate 38 on the steel core body 37 is aligned with the square hole 32 and inserted. The moving ring 34 is released, and under the restoring force of the large spring 33, the moving ring 34 is pushed back to its original position, thereby squeezing the ball 36 so that it is partially embedded in the limiting groove 39 on the outside of the steel core body 37, completing the quick locking. The entire device achieves efficient quick assembly and disassembly without tools through precise structural fit and multi-level linkage, significantly improving assembly convenience and connection reliability.

[0028] Through the above steps, by setting up a linkage structure such as the elastic element 22 and the locking block 23, the steel sleeve and steel core structure is optimized, significantly improving assembly and disassembly efficiency and shortening maintenance and replacement cycles. This structure is stable and reliable, effectively avoiding component wear and loosening of connections caused by frequent disassembly and assembly, reducing reliance on tools, and improving the convenience of on-site operation. It is particularly suitable for occasions that require frequent replacement or maintenance. While improving operation and maintenance efficiency, it also enhances the overall practicality and reliability, solving the problem that existing steel sleeve and steel core structure components mostly use fixed fit and sound-absorbing ring connection, which, although stable, are cumbersome to install and disassemble, requiring tools or even destructive removal, affecting replacement efficiency and maintenance convenience, increasing maintenance costs, and being unfavorable for batch assembly and subsequent maintenance.
