Abstract

The invention discloses a drain tank of a motor home. The drain tank comprises a tank body and a tank cover which are in seamless connection with each other. A storage cavity is formed between the tank cover and the tank body. A drain inlet is formed in the upper portion of the tank cover. A drain pipe is arranged on the upper portion of one end of the tank cover. The drain tank is characterized in that two drag rod cavities are arranged in parallel at the bottom of the box body below the drain pipe and two drag rods correspondingly stretch into the drag rod cavities. The drag rods are arrested in the drag rod cavities through arresting tables at the ends of the drag rods and sealing covers mounted on openings of the drag rod cavities. A pull rod is connected between the two drag rods stretching out of the drag rod cavities. Drag wheels rotatably supporting the tank body are arranged on the two sides of one end, away from the drain pipe, of the tank body. The drain tank is simple in structural design, low in storage space occupancy, reliable in use and convenient to move.

The technical solution adopted for the present invention to solve the technical problems is: a kind of caravan foul water tank, it comprises casing and case lid, described case lid and the seamless link of casing one, and at Inner Constitution one storage chamber of case lid and casing, the dirt inlet of a connection storage chamber is offered on case lid top, the blow-off pipe being communicated with storage chamber is provided with on the top, one end of case lid, it is characterized in that: the bottom half below blow-off pipe is parallel is provided with two drawbar chambeies, two drawbars are corresponding respectively to be stretched in described drawbar chamber, and in drawbar chamber, rely on the limit dais of drawbar end to carry out spacing with the capping being assemblied in drawbar accent place, a pull bar is connected between two drawbars stretching out two drawbar chambeies, the tugboat of rotational support casing is respectively equipped with in the both sides, one end of the casing away from blow-off pipe.

The casing outer end of corresponding pull bar is provided with pull bar locking block.

Recoil spring is respectively equipped with at the bottom of the chamber in two drawbar chambeies and between two drawbars.

Offer groove respectively in the both sides, one end of the casing away from blow-off pipe, two described tugboats respectively correspondence are arranged in this two groove.

The wheel rim of two tugboats and the bottom surface of casing tangent.

The case lid of dirt inlet both sides is arranged with sewage pipe draw-in groove.

Leader is being provided with close on the case lid of blow-off pipe.

The present invention is by case lid and the seamless link of casing one, and at Inner Constitution one storage chamber of case lid and casing, a dirt inlet is offered on case lid top, blow-off pipe is provided with on the top, one end of case lid, bottom half below blow-off pipe is parallel is provided with two drawbar chambeies, two drawbar correspondences stretch in drawbar chamber, connect a pull bar between two drawbars stretching out two drawbar chambeies; The tugboat of rotational support casing is respectively equipped with in the both sides, one end of the casing away from blow-off pipe.Structure design of the present invention is simple, saves placement space, uses reliable, and traditional mode that manually submits is changed into artificial dilatory mode, conveniently moving.

Detailed description of the invention

As Figure 1 and Figure 4, a kind of caravan foul water tank, it comprises case lid 1 and casing 3, case lid 1 and the seamless link of casing 3 one, and at Inner Constitution one storage chamber 11 of case lid 1 with casing 3.

As shown in Figure 1, Figure 2, Figure 4 shows, offer the dirt inlet 7 of a connection storage chamber 11 on case lid 1 top, be provided with the blow-off pipe 2 being communicated with storage chamber 11 on the top, one end of case lid 1.

As shown in Figure 4, parallelly bottom casing 3 below blow-off pipe 2 be provided with two drawbar chambeies 15, two drawbars 14 respectively correspondence stretch in drawbar chamber 15, and in drawbar chamber 15, rely on the limit dais 13 of drawbar 14 end and be assemblied in the capping 16 located in 15 mouthfuls, drawbar chamber and carry out axial spacing.

For ease of the tractive to foul water tank, as shown in Figure 3, Figure 4, between two drawbars 14 stretching out two drawbar chambeies 15, a pull bar 9 is connected.

As shown in Figure 3, Figure 4, in order to prevent drawbar 14 and pull bar 9 from freeing in and out drawbar chamber 15, casing 3 outer end of corresponding pull bar 9 is provided with pull bar locking block 10.For coordinating pull bar locking block 10 pairs of pull bars 9 to lock, at the bottom of the chamber in two drawbar chambeies 15 and between two drawbars 14, be respectively equipped with recoil spring 12.

In FIG, the tugboat 5 of rotational support casing 1 is respectively equipped with in the both sides, one end of the casing 3 away from blow-off pipe 2.

For reduce taking space, as shown in Figure 1, offer groove 4 respectively in the both sides, one end of the casing 3 away from blow-off pipe 2, tugboat 5 respectively correspondence is arranged in this two groove 4, and the wheel rim of two tugboats 5 and the bottom surface of casing 3 tangent.

It should be noted that, the wheel shaft of tugboat 5 can through casing 3 but be not communicated with storage chamber be arranged, and also can arrange at the outside cantilever of casing 3.

As shown in Figure 2, Figure 4 shows, the case lid 1 of dirt inlet 7 both sides is arranged with sewage pipe draw-in groove 6, sewage pipe can be clamped on seal request dirt inlet 7 also meeting both interfaces by actv. by this sewage pipe draw-in groove 6.

As shown in Figure 2, leader 8 is being provided with close on the case lid 1 of blow-off pipe 2, to facilitate holding casing.

For reducing costs, convenient mobile and ensure the corrosion resistance of foul water tank, the conventional plastic material easily obtained all preferentially selected by the case lid 1 stated in fig. 4, the upper, casing 3, drawbar 14 and tugboat 5.

The present invention in use, places it in the commitment positions of caravan, is directly installed on the dirt inlet 7 of casing by sewage pipe by sewage pipe draw-in groove 6.When needs contents discharged, sewage pipe is pulled down by sewage draining exit 7, the handle 8 of foul water tank of holding with a firm grip, pulled out from drawbar chamber 15 by drawbar 14, certain angle is lifted in casing 3 one end and makes casing 3 fully liftoff, now only tugboat 5 contacts with bottom surface, under the dilatory effect of drawbar 14, rolling is advanced; After dirt is got rid of by blow-off pipe 2, drawbar 14 is pushed drawbar chamber 15 and by pull bar locking block 10 to its locking, is placed in original place, connects sewage pipe.

The present invention is rational in infrastructure, conveniently moving, use are reliable.
