Embodiment Construction
[0012] Embodiment of the present invention is described in detail below in conjunction with accompanying drawing:
[0013] An embodiment of a vehicle gas pipe fixing assembly, such as figure 2 As shown, the assembly includes a rigid tube 7 with a rectangular cross-section for fixing on the roof of the compartment and the floor of the compartment at both ends. The rigid tube is a seamless rectangular steel pipe. Two buckle covers 8 and 9 with a cross-section of ] shape, the recesses of the two buckle covers 8 and 9 face each other, and one of the buckle covers 8 is movably inserted into the other buckle cover 9 to form a space for clamping the gas pipe group wrapped by the insulation layer 11 In the clamping space, the insertion parts of the two buckle covers 8, 9 have guide rails 12, and the buckle covers 8, 9 all extend along the lengthwise direction of the hard tube 7.
[0014] When installing a fixed gas pipe, the two buckle covers 8, 9 are first drawn out of the seamless...

The invention relates to an automobile gas pipe fixing assembly comprising a hard pipe. Two buckle covers with ]-shaped cross sections are arranged in the hard pipe in a sliding manner, the concave parts of the two buckle parts are opposite to each other, one of the buckle covers is movably inserted into the other buckle cover to form a clamping space used for clamping a gas pipe group wrapped by a heat insulation layer, guide rails are arranged on the inserting parts of the two buckle covers, and the buckle covers all extend along the lengthwise direction of the hard pipe; and the invention also relates to a passenger car. According to the automobile gas pipe fixing assembly and the passenger car, gas pipes are bound together, fixed clamps for the gas pipes are eliminated, so that the size of a seamless rectangular steel pipe can be designed to be extremely small, further the mounting space is reduced, when the pipes are maintained in the later period, only the buckle covers and the gas pipe group wrapped by the heat insulation layer need to be drawn out of the seamless rectangular steel pipe on a roof, so that the operation is extremely convenient, and the problems that the gas pipe fixing structure occupies a large space, and leakage oil can enter carriage easily in the prior art can be solved.
Description
technical field [0001] The invention relates to a gas pipe fixing assembly for vehicles. The invention also relates to the gas which has the advantages of preventing the gas from leaking into the passenger compartment, convenient installation and maintenance, and small space occupation. Background technique [0002] With the application of LNG buses, a structure that installs LNG gas cylinders on the top has been gradually applied in the field of LNG buses because the distance between the gas cylinders and the ground is higher, and the safety performance of the whole vehicle is better. Go down through the passenger area to reach the liquid filling panel of the chassis and the engine air intake part. The temperature of the LNG in the gas cylinder is extremely low. Fixed structure such as figure 1 As shown, it includes the upper cover 1 of the gas protection sleeve opposite to the concave part and the lower cover 2 of the gas pipe protection sleeve. The lower cover 2 of the g...
