Description

Technical Field

[0001] This utility model relates to the technical field of external connection devices for sanitation vehicles, and in particular to an external connection device for sanitation vehicles. Background Technology

[0002] Sanitation vehicles are a common sight in people's lives. Sanitation workers use them to transport garbage, ensuring that people's living and working environments are clean and tidy. Due to the different types of garbage, when encountering large-volume garbage, a truck bed needs to be added to the outside of the sanitation vehicle for transporting large-volume garbage. At this time, a connecting device is needed to improve the stability of the connection between the truck bed and the sanitation vehicle.

[0003] The existing connection device has a simple structure, cannot achieve impact buffering operation at any angle, has limitations in dealing with complex road environments, and is not easy to flexibly disassemble and assemble, so its practicality needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide an external connection device for sanitation vehicles that can be flexibly installed and disassembled, and can effectively eliminate impact forces from any angle, making it highly practical.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An external connection device for a sanitation vehicle includes a first base, a second spherical universal joint fixedly connected to the middle position of the first base, a telescopic connecting rod connected to one end of the second spherical universal joint, a second base externally sleeved and fixed to one end of the telescopic connecting rod, a plurality of first spherical universal joints fixedly connected to adjacent side surfaces of the first base and the second base, a damping telescopic rod fixedly connected between two corresponding first spherical universal joints, and a spring externally sleeved on the damping telescopic rod.

[0007] By adopting the above technical solution, it can flexibly adapt to the impact force in any direction, effectively cope with complex bumpy road sections, and has strong practicality.

[0008] Furthermore, multiple first spherical universal connectors are arranged in pairs, each in a circular array along the central axis of the telescopic connecting rod.

[0009] By adopting the above technical solution, shock-absorbing operation from multiple angles is ensured.

[0010] Furthermore, a first connector plug is fixedly connected to the middle position of one side of the outer surface of the first base.

[0011] By adopting the above technical solution, it is possible to assemble and disassemble flexibly.

[0012] Furthermore, a first connector is sleeved on the outside of the first connector plug, and a pin hole is provided at the corresponding position on the outer surface of the first connector and the first connector plug, and a first pin screw is inserted into the inside of the pin hole.

[0013] By adopting the above technical solution, the first connector and the first connector plug can be connected in a limiting manner.

[0014] Furthermore, a second connector is fixedly connected to one end of the second base, and a second connector plug is inserted inside the second connector.

[0015] By adopting the above technical solution, flexible assembly and disassembly can be performed.

[0016] Furthermore, each of the second connector plug and the second connector base has a pin hole at a corresponding position on its outer surface, and a second pin screw is inserted into the pin hole.

[0017] By adopting the above technical solution, the second connector and the second connector can be effectively connected.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] This invention incorporates multiple shock-absorbing and buffering structures in the connector by attaching a spring to the outside of the damping telescopic rod. Since these structures are arranged in a circular array on the outside of the telescopic connecting rod, they can buffer impacts in any direction, ensuring a stable connection between the environmentally friendly vehicle and the external connecting structure. Furthermore, the connection point is not subjected to lateral shearing forces when encountering bumpy roads. This device effectively copes with complex road surfaces, is highly practical, and is detachable at both ends for flexible installation during use. It also allows for convenient replacement of damaged parts during subsequent use, offering high flexibility in application. Attached Figure Description

[0023] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 , Figure 2 An external connection device for a sanitation vehicle includes a first base 4, a second spherical universal joint 8 fixedly connected to the middle position of the first base 4, a telescopic connecting rod 9 connected to one end of the second spherical universal joint 8, a second base 10 fixedly sleeved to one end of the telescopic connecting rod 9, and multiple first spherical universal joints 5 fixedly connected to adjacent side surfaces of the first base 4 and the second base 10. A damping telescopic rod 6 is fixedly connected between two corresponding first spherical universal joints 5, and a spring 7 is sleeved on the outside of the damping telescopic rod 6. Multiple first spherical universal connectors 5 are arranged in pairs, all in a circular array along the central axis of the telescopic connecting rod 9. The connector has multiple shock-absorbing and buffering structures by sleeved springs 7 on the outside of the damping telescopic rod 6. Since the multiple shock-absorbing and buffering structures are arranged in a circular array outside the telescopic connecting rod 9, they can perform impact buffering operations in any direction, so that the environmental protection vehicle can be stably connected to the external connection structure. When encountering bumpy road sections, the connection point will not be subjected to lateral shearing force. This device can effectively cope with complex road surfaces and has strong practicality.

[0025] Reference Figure 1 , Figure 2 A first connector 2 is fixedly connected to the middle position of one outer surface of the first base 4. A first connector 1 is sleeved on the outside of the first connector 2. Pin holes are provided at corresponding positions on the outer surfaces of the first connector 1 and the first connector 2, and a first pin screw 3 is inserted into the pin holes. A second connector 11 is fixedly connected to one end of the second base 10. A second connector 12 is inserted into the inside of the second connector 11. Pin holes are provided at corresponding positions on the outer surfaces of the second connector 12 and the second connector 11, and a second pin screw 1 is inserted into the pin holes. 3. When connecting to the external structure, the first connector 2 is first inserted into the socket of the first connector 1, then the first pin screw 3 is inserted into the corresponding pin hole and the nut on the first pin screw 3 is tightened. Then the second connector 11 is fitted onto the outside of the second connector 12, and then the second pin screw 13 is inserted into the corresponding pin hole and the nut on the second pin screw 13 is tightened. At this time, an effective connection operation can be achieved. The device can be flexibly installed during use and the damaged parts can be easily replaced during subsequent use, making it highly flexible in use.

[0026] Working principle: During use, first install the first connector 2 into the socket of the first connector 1, then insert the first pin screw 3 into the corresponding pin hole and tighten the nut on the first pin screw 3. Then, fit the second connector 11 onto the outside of the second connector 12, and then insert the second pin screw 13 into the corresponding pin hole and tighten the nut on the second pin screw 13. At this time, an effective connection operation can be achieved. After the connection is completed, it can be used normally. During use, by attaching a spring 7 to the outside of the damping telescopic rod 6, the connector has multiple shock-absorbing and buffering structures. Since the multiple shock-absorbing and buffering structures are arranged in a circular array on the outside of the telescopic connecting rod 9, impact buffering operation can be performed in any direction, so that the environmental protection vehicle can be stably connected with the external connection structure. When encountering bumpy road sections, the connection point will not be subjected to lateral shear force. This device can effectively cope with complex road surfaces and is highly practical.
