Description

Technical Field

[0001] This utility model relates to the field of shock absorber spring technology, specifically a shock absorber spring with easily adjustable elastic force. Background Technology

[0002] Vibration damping springs are crucial components in automobiles, machinery, and other equipment. Vibration is inevitable during the operation of various vehicles and industrial machinery. Vibration damping springs effectively mitigate this problem. They can quickly absorb and disperse the energy generated by vibrations, transforming originally strong and impactful shocks into relatively gentle fluctuations.

[0003] When a car is driving over bumpy roads, shock absorber springs can significantly reduce the undulation and sway of the vehicle body, providing passengers with a smoother and more comfortable ride. In industrial equipment operation, it reduces vibration damage to the equipment itself and other components, extends the equipment's lifespan, reduces the frequency of maintenance and replacement, and ensures stable production operations.

[0004] According to the utility model disclosed in patent authorization announcement number CN218844955U, the spring shock absorber includes a support plate and a chassis. Three sets of connecting components are connected between the support plate and the chassis. A shock-absorbing spring is connected in the middle between the support plate and the chassis. A limit structure is provided inside the shock-absorbing spring. Each set of connecting components includes a first universal ball, which is fixed to the bottom of the support plate by a connecting column. A second universal ball sleeve is fixed to the top of the chassis. A second universal ball is movably connected inside the second universal ball sleeve. An outer sleeve is fixed to the top of the second universal ball.

[0005] However, the inconvenience of adjusting the spring force in shock absorber springs limits their applicability. When dealing with equipment of varying weights or operating conditions, the spring force cannot be flexibly adjusted to match the required performance. For example, in industrial machinery that needs to dynamically adapt to load changes, a fixed spring force may result in over-damping under light loads and under-damping under heavy loads. Furthermore, after long-term use, the springs experience performance degradation, which is difficult to restore to optimal damping performance through simple adjustments, affecting equipment stability and lifespan, and increasing maintenance costs and complexity. Utility Model Content

[0006] The purpose of this utility model is to provide a shock-absorbing spring device that is easy to adjust the elastic force, thus solving the problem that the shock-absorbing spring device is inconvenient to adjust the elastic force of the spring during use, which limits its applicable scenarios.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing spring device with adjustable elasticity, comprising a base, a sliding rod slidably connected inside the base, a top plate fixedly connected to the upper end of the sliding rod, a damping block fixedly connected to the lower end of the sliding rod, the damping block slidably connected to the base, an air hole opened inside the base, a sliding plate slidably connected inside the base, a first spring disposed inside the base, a threaded rod rotatably connected inside the base, the threaded rod being threadedly connected to the sliding plate, a knob fixedly connected to the lower end of the threaded rod, the knob being rotatably connected to the base, and a limit mechanism disposed on the base.

[0008] Preferably, a baffle is fixedly connected inside the base, and the slide rod is slidably connected to the baffle. The design of the baffle can limit the movement of the slide rod.

[0009] Preferably, one end of the first spring contacts the slide bar, and the other end of the first spring contacts the slide plate. Through the design of the first spring, the damping block can be driven to reset.

[0010] Preferably, a limiting plate is fixedly connected to the upper end of the threaded rod. The limiting plate contacts the slide plate, and the limiting plate can limit the movement of the slide plate.

[0011] Preferably, a retaining ring is fixedly connected to the outer side of the threaded rod, and the retaining ring contacts the inner wall of the base. The retaining ring is designed to limit the movement of the threaded rod.

[0012] Preferably, the limiting mechanism includes a limiting frame, which is slidably connected to the outer side of the base. A locking block is fixedly connected to the side of the limiting frame near the base. A locking groove is provided inside the knob. The locking block is slidably connected to the base and the knob. A guide rod is fixedly connected to the outer side of the limiting frame. A guide block is fixedly connected to the outer side of the base. The guide block is slidably connected to the limiting frame and the guide rod. A second spring is provided on the outer side of the guide rod. Through the design of the limiting mechanism, the knob can be limited.

[0013] Preferably, one end of the second spring contacts the guide block, and the other end of the second spring contacts the limiting frame. Through the design of the second spring, the limiting frame can be driven to limit the knob.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by incorporating components such as a sliding plate, a threaded rod, and a knob, allows for the rotation of the threaded rod to induce a threaded motion between the threaded rod and the sliding plate. This causes the sliding plate to compress the first spring, thereby adjusting the spring force of the first spring. This solves the problem that shock absorber springs are inconvenient to adjust the spring force during use, which limits their applicability.

[0016] 2. By setting up components such as a limit frame, a locking block, and a second spring, the locking block on the limit frame can be driven by the elastic force of the second spring to slide into the locking groove on the knob, thereby limiting the knob and keeping the slide plate stable after adjustment.

[0024] Please see Figure 2-4 One end of the first spring 31 contacts the slide bar 2, and the other end of the first spring 31 contacts the slide plate 3. The design of the first spring 31 can drive the damping block 23 to reset. The base 1 is internally connected to a threaded rod 32, which is connected to the slide plate 3 by a thread. The upper end of the threaded rod 32 is fixedly connected to a limit plate 33, which contacts the slide plate 3. The design of the limit plate 33 can limit the slide plate 3. The outer side of the threaded rod 32 is fixedly connected to a retaining ring 34, which contacts the inner wall of the base 1. The design of the retaining ring 34 can limit the threaded rod 32. The lower end of the threaded rod 32 is fixedly connected to a knob 35, which is rotatably connected to the base 1. The base 1 is provided with a limit mechanism 4.

[0025] Please see Figure 2-4 The limiting mechanism 4 includes a limiting frame 41. The limiting frame 41 is slidably connected to the outer side of the base 1. A locking block 42 is fixedly connected to the side of the limiting frame 41 near the base 1. A locking groove 43 is opened inside the knob 35. The locking block 42 is slidably connected to the base 1 and the knob 35. A guide rod 44 is fixedly connected to the outer side of the limiting frame 41. A guide block 45 is fixedly connected to the outer side of the base 1. The guide block 45 is slidably connected to the limiting frame 41 and the guide rod 44.

[0026] The specific implementation process of this utility model is as follows: When in use, by moving the limiting frame 41 away from the base 1, the limiting frame 41 drives the guide rod 44 to slide in the guide block 45, so that the limiting frame 41 squeezes the second spring 46, and the limiting frame 41 drives the locking block 42 to slide out of the locking groove 43 on the knob 35, so that the limiting of the knob 35 can be released.

[0027] By rotating the knob 35, the knob 35 drives the threaded rod 32 to rotate, causing the threaded rod 32 to move in a threaded motion with the slide plate 3, thereby causing the slide plate 3 to move on the threaded rod 32 and slide within the base 1, so that the slide plate 3 compresses the first spring 31, thereby adjusting the elastic force of the first spring 31.
