Description

Technical Field

[0001] This utility model relates to the technical field of shock-absorbing pad limiting devices, specifically a shock-absorbing pad limiting structure. Background Technology

[0002] Vibration damping pads are widely used in automotive engine compartments, chassis suspension systems, industrial equipment bases, and other applications. As industrial equipment demands increasingly stringent vibration control requirements, the limiting stability of vibration damping pads has become a key performance indicator.

[0003] Traditional shock-absorbing pads are usually laid directly at the bottom of the equipment and rely solely on friction to achieve positioning. Under complex working conditions such as high-frequency vibration, temperature changes, and oil corrosion, they are prone to lateral displacement, which can easily cause abnormal noises from the equipment. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a shock-absorbing pad limiting structure.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing pad limiting structure, comprising a base body, a cylindrical tube, an equipment support rod, and a shock-absorbing pad. The upper end of the base body is provided with a protrusion, the shock-absorbing pad is placed on the upper end of the base body, and the lower end of the shock-absorbing pad is provided with a positioning groove. The protrusion is inserted into the interior of the positioning groove. The cylindrical tube is installed on the upper end of the base body, and the shock-absorbing pad is inserted into the interior of the cylindrical tube. The bottom of the equipment support rod is inserted into the interior of the cylindrical tube, and the bottom end contacts the top end of the shock-absorbing pad.

[0008] The upper end of the base tube body is provided with an annular threaded groove, the lower end of the cylindrical tube is provided with a base plate, and the lower end of the base plate is provided with an annular frame that is inserted into the annular threaded groove. The annular frame is threadedly connected to the annular threaded groove.

[0009] The equipment support rod at the bottom of the device is inserted into the cylindrical tube and squeezes the shock-absorbing pad. When the shock-absorbing pad is in use, the center is limited by the protrusion and the periphery is limited by the cylindrical tube, so that it will not shake on the bottom body.

[0010] To improve the stability of the shock-absorbing pad during use, the improvement of this utility model is that the outer wall of the protrusion is closely fitted to the inner wall of the positioning groove, and the outer wall of the shock-absorbing pad is closely fitted to the inner wall of the cylindrical tube.

[0011] Furthermore, an improvement of this utility model is that the protrusion is fixed at the center of the base plate.

[0012] To facilitate the insertion of the equipment support rod into the cylindrical tube, the present invention includes an improvement where a tapered sleeve is provided at the upper end of the cylindrical tube.

[0013] Furthermore, the present invention includes an annular limiting groove on the inner wall of the cylindrical tube, a shock-absorbing ring inside the annular limiting groove, and the inner wall of the shock-absorbing ring tightly fitting the outer wall of the equipment support rod.

[0014] The annular limiting groove can limit the movement of the damping ring, and the damping ring can dampen the horizontal vibration of the equipment support rod.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a shock-absorbing pad limiting structure, which has the following beneficial effects:

[0017] By using the protrusions on the base plate to cooperate with the positioning grooves of the damping pad, and the cylindrical tube to limit the circumference of the damping pad, the damping pad is stabilized from both the center and the periphery, which greatly improves the limiting stability of the damping pad on the base plate and effectively avoids the shaking and displacement of the damping pad under complex working conditions. Compared with the traditional method of limiting by friction alone, the stability is significantly improved. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model discloses a shock-absorbing pad limiting structure, including a base body 1, a cylindrical tube 6, an equipment support rod 8, and a shock-absorbing pad 4. The base body 1 has a protrusion 3 at its upper end, the shock-absorbing pad 4 is placed at the upper end of the base body 1, and the lower end of the shock-absorbing pad 4 has a positioning groove 5. The protrusion 3 is inserted into the interior of the positioning groove 5. The cylindrical tube 6 is installed at the upper end of the base body 1, and the shock-absorbing pad 4 is inserted into the interior of the cylindrical tube 6. The bottom of the equipment support rod 8 is inserted into the interior of the cylindrical tube 6 and its bottom end contacts the top end of the shock-absorbing pad 4.

[0025] The upper end of the base body 1 is provided with an annular threaded groove 2, and the lower end of the cylindrical tube 6 is provided with a base plate 10. The lower end of the base plate 10 is provided with an annular frame 11 that is inserted into the annular threaded groove 2, and the annular frame 11 is threadedly connected to the annular threaded groove 2.

[0026] In this shock-absorbing pad 4-limiting structure, the stable support and shock absorption of the equipment are achieved through the coordinated work of multiple components.

[0027] The outer wall of the protrusion 3 is tightly fitted to the inner wall of the positioning groove 5, the outer wall of the shock-absorbing pad 4 is tightly fitted to the inner wall of the cylindrical tube 6, and the protrusion 3 is fixed at the center of the bottom base body 1.

[0028] First, place the shock-absorbing pad 4 on the upper end of the base body 1. The protrusion 3 on the base body 1 will be inserted into the positioning groove 5 at the lower end of the shock-absorbing pad 4, and the outer wall of the protrusion 3 will be tightly fitted with the inner wall of the positioning groove 5. Since the protrusion 3 is fixed at the center of the base body 1, it plays a preliminary limiting role on the shock-absorbing pad 4 from the center position, limiting the displacement of the shock-absorbing pad 4 in the horizontal direction.

[0029] Next, the cylindrical tube 6 is installed on the upper end of the base body 1. At this time, the shock-absorbing pad 4 is inserted into the cylindrical tube 6, and the outer wall of the shock-absorbing pad 4 is tightly attached to the inner wall of the cylindrical tube 6. The cylindrical tube 6 limits the shock-absorbing pad 4 from the periphery, further preventing the shock-absorbing pad 4 from shaking or displacing, and ensuring that the shock-absorbing pad 4 remains stable on the base body 1.

[0030] The upper end of the cylindrical tube 6 is provided with a conical sleeve 7.

[0031] During equipment installation, the equipment support rod 8 at the bottom of the equipment is inserted into the cylindrical tube 6. The weight of the equipment will cause the bottom of the equipment support rod 8 to press against the shock-absorbing pad 4. During this process, the conical sleeve 7 at the upper end of the cylindrical tube 6 acts as a guide, facilitating the smooth insertion of the equipment support rod 8 into the cylindrical tube 6.

[0032] The inner wall of the cylindrical tube 6 is provided with an annular limiting groove 12, and a shock-absorbing ring 9 is provided in the annular limiting groove 12. The inner wall of the shock-absorbing ring 9 is tightly attached to the outer wall of the equipment support rod 8.

[0033] Furthermore, a damping ring 9 is installed within the annular limiting groove 12 on the inner wall of the cylindrical tube 6. The inner wall of the damping ring 9 is tightly fitted against the outer wall of the equipment support rod 8. When the equipment vibrates during operation, especially horizontal vibrations, the damping ring 9 can absorb and buffer the vibration energy transmitted from the equipment support rod 8, reducing the impact of vibration on the overall equipment. The annular limiting groove 12 also limits the damping ring 9, ensuring its stability during operation and continuously and effectively damping the equipment support rod 8.

[0034] The tapered sleeve 7 at the upper end of the cylindrical tube 6 provides guidance for the insertion of the equipment support rod 8, reduces the difficulty of installation, improves the installation efficiency, makes the equipment installation process more convenient and faster, and reduces the time and labor costs required for installation.

[0035] The shock-absorbing pad's four-position limiting structure features rationally designed components, a simple structure, and is easy to manufacture and install. Furthermore, the tight fit between the components ensures stable performance of both limiting and shock-absorbing functions, resulting in high reliability. It is suitable for various equipment scenarios requiring shock absorption and limiting, and has broad application value.
