[0002] Loaders, excavators and other construction machinery are mainly used in mines, gravel quarries, heavy construction projects and other occasions. The vibration during operation is large. The impact generated during operation will be transmitted to the connection structure between the fuel tank, hydraulic oil tank and the frame. This will not only cause the tank to vibrate frequently, thus generating a lot of noise, but also cause the connection structure to fail and deform, affecting the installation stability of the tank and making it easy for the tank to shift or fall off. Utility Model Content

[0003] In view of the above-mentioned deficiencies or defects in the existing technology, this utility model provides a shock-absorbing connection structure and operating machinery, aiming to solve the technical problems of frequent vibration of the housing in operating machinery, resulting in large noise and poor installation stability.

[0004] To achieve the above objectives, this utility model provides a shock-absorbing connection structure, which includes a first elastic pad, a first connecting plate, a second elastic pad, a second connecting plate, and a fastening assembly. The first elastic pad, the first connecting plate, the second elastic pad, and the second connecting plate are stacked sequentially along a first direction and fastened together by the fastening assembly. A first protrusion extending along a second direction is formed on the side of the first elastic pad that abuts against the first connecting plate. A second protrusion extending along a third direction is formed on the side of the second elastic pad that abuts against the first connecting plate. Both the second direction and the third direction are perpendicular to the first direction, and the second direction and the third direction are set at an angle.

[0005] Optionally, the fastening assembly includes a bolt and a nut, the bolt passing sequentially through the first elastic pad, the first connecting plate, the second elastic pad, and the second connecting plate, and the nut being threaded onto the tail of the bolt.

[0006] Optionally, the shock-absorbing connection structure includes multiple sets of fastening components, which are arranged at intervals.

[0007] Optionally, the shock-absorbing connection structure further includes a metal plate disposed between the head of the bolt and the first elastic pad.

[0008] Optionally, the first elastic pad is a rubber pad, and the first elastic pad is vulcanized and bonded to the metal plate as a whole.

[0009] Optionally, the shock-absorbing connection structure further includes a metal ring disposed between the nut and the second elastic pad.

[0010] Optionally, the second elastic pad is a rubber pad, and the second elastic pad is vulcanized and bonded to the metal ring as a single unit.

[0011] Optionally, the metal ring is threadedly connected to the bolt.

[0012] Optionally, the second direction and the third direction are set perpendicularly.

[0013] This utility model also provides a working machine, the working machine comprising:

[0014] Box;

[0015] frame;

[0016] In the above-described shock-absorbing connection structure, the first connecting plate is fixedly connected to the housing, and the second connecting plate is fixedly connected to the frame.

[0017] Through the above technical solution, the shock-absorbing connection structure of this utility model includes a first elastic pad, a first connecting plate, a second elastic pad, and a second connecting plate stacked sequentially. The first and second elastic pads, respectively, have a first and a second convex strip arranged at an angle on their sides abutting against the first connecting plate. This arrangement, through the elastic deformation of the first and second convex strips, allows the shock-absorbing connection structure to significantly alleviate impacts from multiple directions during use, exhibiting excellent shock absorption and buffering performance. When practically applied to machinery, the first connecting plate connects to the housing, and the second connecting plate connects to the frame, allowing the housing to be installed on the frame via the shock-absorbing connection structure. Because the shock-absorbing connection structure possesses excellent shock absorption and buffering performance, it can prevent frequent vibration of the housing during operation, thereby reducing noise. Simultaneously, the shock-absorbing connection structure is not prone to failure or deformation, effectively improving the installation stability of the housing.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] This utility model first provides a shock-absorbing connection structure.

[0030] In one embodiment, reference is made to the appendix. Figure 2 and attached Figure 3 As shown, the shock-absorbing connection structure includes a first elastic pad 1, a first connecting plate 2, a second elastic pad 3, a second connecting plate 4, and a fastening assembly 5. The first elastic pad 1, the first connecting plate 2, the second elastic pad 3, and the second connecting plate 4 are stacked sequentially along a first direction and fastened together by the fastening assembly 5. A first protrusion 11 extending along a second direction is formed on the side of the first elastic pad 1 that abuts against the first connecting plate 2. A second protrusion 31 extending along a third direction is formed on the side of the second elastic pad 3 that abuts against the first connecting plate 2. Both the second direction and the third direction are perpendicular to the first direction and are set at an angle to each other.

[0031] The shock-absorbing connection structure in this embodiment includes a first elastic pad 1, a first connecting plate 2, a second elastic pad 3, and a second connecting plate 4 stacked sequentially. The first elastic pad 1 and the second elastic pad 3, respectively, have a first protrusion 11 and a second protrusion 31 arranged at an angle on their sides abutting against the first connecting plate 2. This arrangement, through the elastic deformation of the first protrusion 11 and the second protrusion 31, allows the shock-absorbing connection structure to significantly alleviate impacts from multiple directions during use, exhibiting excellent shock absorption and buffering performance. In practical applications on machinery, the first connecting plate 2 connects to the housing, and the second connecting plate 4 connects to the frame, allowing the housing to be installed on the frame via the shock-absorbing connection structure. Because the shock-absorbing connection structure has excellent shock absorption and buffering performance, it can prevent frequent vibration of the housing during operation, thereby reducing noise. Simultaneously, the shock-absorbing connection structure is not prone to failure or deformation, effectively improving the installation stability of the housing.

[0032] Specifically, the first elastic pad 1 and the second elastic pad 3 can be rubber pads.

[0033] In one embodiment, reference is made to the appendix. Figure 2 and attached Figure 3 As shown, the fastening assembly 5 includes a bolt and a nut. The bolt passes through the first elastic pad 1, the first connecting plate 2, the second elastic pad 3, and the second connecting plate 4 in sequence, and the nut is threaded onto the tail of the bolt.

[0034] Understandably, the first elastic pad 1, the first connecting plate 2, the second elastic pad 3, and the second connecting plate 4 are respectively provided with aligned connecting through holes. Bolts pass through multiple connecting through holes, and the first elastic pad 1, the first connecting plate 2, the second elastic pad 3, and the second connecting plate 4 are fastened together and are easy to disassemble and assemble by clamping the head of the bolt and the nut.

[0035] Further, refer to the appendix Figure 2 As shown, the shock-absorbing connection structure includes multiple sets of fastening components 5, which are arranged at intervals. This arrangement effectively improves the connection strength of the fastening connection between the first elastic pad 1, the first connecting plate 2, the second elastic pad 3, and the second connecting plate 4, thereby improving the connection reliability.

[0036] In practical applications, the vibration damping connection structure may include two sets of fastening components 5, which are arranged at intervals to form a double-bolt fastening structure.

[0037] In one embodiment, reference is made to the appendix. Figure 2 and attached Figure 3 As shown, the shock-absorbing connection structure also includes a metal plate 6 disposed between the head of the bolt and the first elastic pad 1. This arrangement allows the first elastic pad 1 to be subjected to more uniform force, effectively improving the service life of the first elastic pad 1 and preventing the first elastic pad 1 from cracking due to concentrated force.

[0038] Furthermore, the first elastic pad 1 is a rubber pad, and the first elastic pad 1 is vulcanized and bonded to the metal plate 6 as a whole. This arrangement makes the first elastic pad 1 and the metal plate 6 form a whole, which improves the connection strength of the first elastic pad 1 and effectively prevents the first elastic pad 1 from falling off due to vibration.

[0039] In one embodiment, reference is made to the appendix. Figure 2 and attached Figure 3 As shown, the shock-absorbing connection structure also includes a metal ring 7 disposed between the nut and the second elastic pad 3. This arrangement allows the second elastic pad 3 to be subjected to more uniform force, effectively improving the service life of the second elastic pad 3 and preventing the second elastic pad 3 from cracking due to concentrated force.

[0040] Furthermore, the second elastic pad 3 is a rubber pad, and it is vulcanized and bonded to the metal ring 7 as a single unit. This design ensures that the second elastic pad 3 and the metal ring 7 are molded into a single entity, improving the connection strength of the second elastic pad 3 and effectively preventing it from detaching due to vibration.

[0041] In one embodiment, the metal ring 7 is threadedly connected to the bolt. This configuration creates a double-nut anti-loosening structure between the metal ring 7 and the nut, effectively preventing the bolt connection from loosening during use and significantly improving the stability of the structure.

[0042] In one embodiment, the second and third directions are arranged perpendicularly. This arrangement further enables the shock-absorbing connection structure to significantly mitigate impacts from multiple directions, exhibiting excellent shock absorption and buffering performance, i.e., good shock absorption effect.

[0043] This utility model also proposes a working machine.

[0044] In one embodiment, reference is made to the appendix. Figure 1 As shown, the operating machinery includes:

[0045] Box 8;

[0046] Rack 9;

[0047] The shock-absorbing connection structure has a first connecting plate 2 fixedly connected to the housing 8 and a second connecting plate 4 fixedly connected to the frame 9.
