Title:
VEHICLE COMPARTMENT HEATING CONNECTION DEVICE AND WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/178947
Kind Code:
A1
Abstract:
A vehicle compartment heating connection device and a work machine, relating to the technical field of vehicle compartment heating devices. The connection device comprises a first connection pipe (100), a second connection pipe (200), an elastic connection assembly (300) and a guide mechanism (400), one end of the first connection pipe (100) being in slidable sleeving connection with one end of the second connection pipe (200), the other end of the first connection pipe (100) being used for being connected to a heating hole in the bottom of a vehicle compartment, the other end of the second connection pipe (200) being used for lap joint with an exhaust pipe, the first connection pipe (100) and the second connection pipe (200) being elastically connected by means of the elastic connection assembly (300), and the guide mechanism (400) being mounted between the first connection pipe (100) and the second connection pipe (200). The elastic connection assembly (300) can enable the second connection pipe (200) to have a force for tightly pressing the exhaust pipe, thereby effectively reducing leakage of exhaust gas; and the guide mechanism (400) is mounted between the first connection pipe (100) and the second connection pipe (200), so that the second connection pipe (200) is provided with guiding constraints when sliding relative to the first connection pipe (100), and a phenomenon of getting stuck is not liable to occur therebetween, thereby effectively protecting the vehicle compartment heating connection device.
