Description

Technical Field

[0001] This utility model relates to the field of buffer connecting rod technology, and in particular to a multi-stage buffer connecting rod device with a rubber bushing. Background Technology

[0002] Buffer connecting rods are a type of connection and vibration damping element widely used in mechanical equipment, vehicle suspensions, engineering structures, and other fields. They are mainly used to absorb impact and vibration energy while transmitting loads, thereby improving system stability and component lifespan.

[0003] Traditional buffer connecting rods often use springs as the core buffer medium, relying on the elastic deformation of the springs to achieve vibration reduction. However, such designs mostly expose the springs directly to the external environment, making them susceptible to dust, moisture, corrosive media, and mechanical impacts during long-term use. This can lead to spring corrosion, fatigue damage, or jamming, thereby reducing the buffering effect and service life. Furthermore, maintenance and replacement are inconvenient. To solve these problems, this utility model proposes a multi-stage buffer connecting rod device with rubber bushings. Utility Model Content

A first mounting plate and a second mounting plate are fixedly connected to the side walls of the first and second connecting plates, respectively. A mounting rod and a fixing cylinder are fixedly connected to the side walls of the first and second mounting plates, respectively. A rectangular block is fixedly connected to the side wall of the mounting rod, and the rectangular block is slidably connected to the fixing cylinder. The first mounting plate is elastically connected to the second mounting plate via a spring. The side walls of the first and second mounting plates share a protective mechanism for the protective spring. The protective mechanism includes rubber bushings disposed on the first and second mounting plates. The side walls of the rubber bushings have two clamping rings, each with a through groove on its side wall. A screw is disposed within each of the two through grooves, and two nuts are threaded onto the screws. The side walls of the nuts are provided with a driving mechanism for rotating the nuts.

[0006] Preferably, the driving mechanism includes two rotating rods fixedly connected to the side wall of the nut, and the rotating rods are inclined.

[0007] Preferably, the side wall of the first connecting plate is adhesively connected with a plurality of first rubber pads, and the side wall of the second connecting plate is adhesively connected with a plurality of second rubber pads.

[0010] Preferably, both the first mounting plate and the second mounting plate have multiple rectangular grooves on their sidewalls, and the multiple rectangular grooves are equally spaced. The sidewall of the rubber bushing is fixedly connected with two positioning rings.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This device is equipped with a protective mechanism. The rubber bushing can provide comprehensive protection for the spring and internal sliding components, avoiding external environmental corrosion and mechanical damage, extending the service life of the device. In addition, the rubber bushing is fixed with clamps, screws and nuts, which is simple in structure, easy to disassemble and assemble, and convenient for maintenance and replacement.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-4 As shown, a multi-stage buffer connecting rod device with a rubber bushing includes a first connecting plate 1 and a second connecting plate 8. A first mounting plate 2 and a second mounting plate 6 are fixedly connected to the side walls of the first connecting plate 1 and the second connecting plate 8, respectively. A mounting rod 4 and a fixing cylinder 7 are fixedly connected to the side walls of the first mounting plate 2 and the second mounting plate 6, respectively. A rectangular block 5 is fixedly connected to the side wall of the mounting rod 4. The rectangular block 5 and the fixing cylinder 7 are slidably connected. The first mounting plate 2 is elastically connected to the second mounting plate 6 through a spring 3.

[0016] The first mounting plate 2 and the second mounting plate 6 are both provided with a protective mechanism of protective spring 3 on their side walls. The protective mechanism includes a rubber bushing 9 on the first mounting plate 2 and the second mounting plate 6. The rubber bushing 9 is integrally formed with the positioning ring 12. The side wall of the rubber bushing 9 has an incompletely cut gap along the axial direction (length direction). It is worth noting that it is not composed of two parts, but can be opened and closed. Therefore, the rubber bushing 9 can be replaced on the first mounting plate 2 and the second mounting plate 6. The side wall of the rubber bushing 9 is provided with two clamping rings 11. Both sides of the clamping rings 11 are provided with through grooves. The two through grooves are provided with screws 10. Two nuts 13 are threadedly connected to the screws 10.

[0017] The nut 13 has a drive mechanism on its side wall for driving the nut 13 to rotate. The drive mechanism includes two rotating rods 14 fixedly connected to the side wall of the nut 13, and the rotating rods 14 are inclined.

[0018] In this utility model, a plurality of first rubber pads 15 are glued to the side wall of the first connecting plate 1, and a plurality of second rubber pads 16 are glued to the side wall of the second connecting plate 8. The four first rubber pads 15 are equally spaced, and the four second rubber pads 16 are equally spaced, which can provide secondary buffering for the first mounting plate 2 and the second mounting plate 6, thereby achieving multi-level buffering.

[0019] In this utility model, a first limiting ring 18 is provided on the side wall of the first rubber pad 15. The first limiting ring 18 is fixedly connected to the first connecting plate 1, which can provide positioning for the replacement of the first rubber pad 15 and ensure that the positions of the four first rubber pads 15 remain unchanged.

[0020] In this utility model, the side wall of the second rubber pad 16 is provided with a second limiting ring 19, which is fixedly connected to the second connecting plate 8. This provides positioning for replacing the second rubber pad 16 and ensures that the positions of the four second rubber pads 16 remain unchanged.

[0021] In this utility model, the side walls of the first mounting plate 2 and the second mounting plate 6 are provided with multiple rectangular grooves 17. The multiple rectangular grooves 17 are equally spaced to increase the contact area between the rubber bushing 9 and the first mounting plate 2 and the second mounting plate 6, and to prevent them from rotating at will. The side wall of the rubber bushing 9 is fixedly connected with two positioning rings 12. The positioning rings 12 are clamping rings 11 placed on the first mounting plate 2 and the second mounting plate 6 for positioning.

[0022] When the device is subjected to axial impact or vibration load, relative displacement occurs between the first connecting plate 1 and the second connecting plate 8. The spring 3 first undergoes compression deformation, absorbing most of the impact energy and achieving the first-level buffer. The rubber bushing 9 wraps around the spring 3 and the internal sliding components (such as the mounting rod 4, rectangular block 5 and fixed cylinder 7), effectively isolating external dust, moisture and collisions, protecting the core buffer components from damage, and extending service life. The rubber bushing 9 is fixed to the screw 10 and nut 13 by the clamping ring 11, which is easy to disassemble and facilitates daily inspection and replacement. When the impact load is large, after the spring 3 is compressed to a certain stroke, the first mounting plate 2 or the second mounting plate 6 will contact the first rubber pad 15 or the second rubber pad 16 respectively. The rubber pad will undergo further elastic deformation, providing additional buffering effect and forming a second-level buffer. This multi-level buffering mechanism enables the device to cope with daily small vibrations and effectively attenuate large impacts, thereby improving the reliability and stability of the overall system.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
