DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5 The utility model provides a diesel engine oil consumption measuring device, and the technical scheme is as follows:

[0025] A diesel engine oil consumption measuring device comprises a platform scale 1 and a collection box 2. The collection box 2 is placed on the platform scale 1. Four supporting legs 4 are fixedly connected to the bottom of the platform scale 1. The platform scale 1 is equipped with a level. A supporting device is provided on the outer wall of the collection box 2.

[0026] The collecting box 2 is placed at the drain position of the engine oil pan, the drain plug is loosened, and the oil is drained after reaching the drain temperature. After half an hour or one hour according to the requirements, the drain screw hole is blocked with the drain plug and tightened.

[0027] Pour the engine oil into another collecting box 2, weigh it and take a photo, then add it to the engine, weigh the collecting box 2 after refueling and take a photo, the weight of the collecting box 2 after refueling minus the weight of the collecting box 2 before refueling is the net weight of the added engine oil, add oil until the oil level reaches the upper dead center of the oil dipstick, so as to record and calculate the relevant measurement data of the engine oil consumption.

[0028] The specific operation of using the collection box 2 is as follows: after placing the diesel or engine oil, manually operate the support device to support the body of the collection box 2, move the collection box 2 to the platform scale 1, and then weigh and record the weight. The support device includes: a sleeve 13, a sliding rod 5, a support wheel 7, a crossbar 6, and a vertical rod 8. There are four sleeves 13, and the four sleeves 13 are fixedly installed on the outer wall of the collection box 2. There are four sliding rods 5, which are respectively slidably installed on the sleeves 13. The tops of two adjacent sliding rods 5 are commonly fixedly connected with a crossbar 6, and the middle top wall of the crossbar 6 is fixedly connected with a vertical rod 8. The two side walls of the collection box 2 are fixedly connected with fixed rods 10, and the fixed rod 10 is provided with a thrust assembly, and the thrust assembly is connected to the vertical rod 8.

[0029] The manually operated thrust assembly drives the vertical rod 8 to move in the vertical direction, and then drives the horizontal axis to move in the vertical direction, and drives the sliding rod 5 to move in the vertical direction, so that the support wheel 7 at the bottom of the sliding rod 5 contacts the ground, and provides an upward support force to the collection box 2 under the thrust, propping up the support box, and the bottom of the support wheel 7 can rotate to push it to move, and the height of the support wheel 7 is higher than the height of the weighing platform of the platform scale 1, which can directly push the collection box 2 to move to the weighing platform of the platform scale 1 and place it, and then lift the support wheel 7 off the ground through the thrust assembly, and then weigh it. This arrangement allows the movement and weighing of the collection box 2 to be completed by only one person.

[0030] like Figure 2 As shown, four fixed rods 10 are provided, and the four fixed rods 10 are evenly distributed on the two side walls of the collecting box 2. The thrust assembly includes a connecting rod 11 and a connecting rod 12. The connecting rod 11 and the connecting rod 12 are respectively rotatably mounted on the fixed rod 10. One end of the connecting rod 11 and the connecting rod 12 are rotatably connected to the vertical rod 8. The end of the connecting rod 2 12 away from the vertical rod 8 is fixedly connected to a rotating rod 9, and the rotating rod 9 is fixedly connected to a rocker 3.

[0031] A person holds the rocker 3 and pushes it, so that it drives the rotating rod 9 to make an arc motion. The rotating rod 9 drives the second connecting rod 12 to rotate around the fixed rod 10. The connecting rod 11 and the second connecting rod 12 work together to convert the arc motion trajectory of the rotating rod 9 into a linear motion trajectory of the vertical rod 8, and the rocker 3 and its action also form a lever mechanism to achieve a labor-saving effect.

[0032] like Figure 2 and Figure 4As shown, a sleeve 19 is fixedly installed on the side wall of the collection box 2, and a slide bar 18 is slidably installed in the sleeve 19. A spring 20 is provided between the slide bar 18 and the sleeve 19, and the end of the slide bar 18 facing away from the sleeve 19 is provided with a chamfer, and the top of the rotating rod 9 is also provided with a chamfer. When the collection box 2 needs to be supported, a person holds the rocker 3 and pushes it upward to move the sliding rod 5 downward. When the rocker 3 is pushed upward, the rotating rod 9 contacts the chamfer of the slide bar 18, pushing the slide bar 18 to compress the spring 20 and move inside the sleeve 19. When the rotating rod 9 is rotated to above the slide bar 18, the slide bar 18 pops out to limit the rotating rod 9, thereby making the sliding rod 5 and the supporting wheel 7 limited and fixed, and continuously supporting the collection box 2. When the supporting wheel 7 needs to leave the ground to cancel the support, a person presses the slide bar 18 manually to cancel the limit on the rotating rod 9.

[0033] like Figure 3 As shown, a cavity is provided in the support foot 4, and a screw rod 15 and a screw rod 2 16 are threadedly connected to the support foot 4, and the screw rod 15 and the screw rod 2 16 have opposite threading directions, and one end of the screw rod 15 is fixedly connected to the bottom wall of the platform scale 1, and a bottom plate 17 is fixedly installed at the bottom of the screw rod 2 16. A slide rail is also provided on the side wall of the collection box 2, and a connecting block is provided on the cross bar 6, and the connecting block is slidably connected in the slide rail. The slide rail and the cross bar 6 are connected to limit the collection box 2 in the horizontal direction so that it does not rotate and tip over during the up and down movement.

[0034] The balance of the weighing platform of the platform scale 1 has an important influence on the accuracy. The platform scale 1 is equipped with a spirit level to observe the horizontal condition of the platform scale 1. If imbalance occurs, the support foot 4 can be rotated to adjust the distance between the screw rod 15 and the screw rod 2 16, thereby achieving leveling of the platform scale 1.

[0035] The sliding rod 5 includes a limiting rod 501, a rotating rod 502, and a torsion spring 503. The limiting rod 501 is slidably installed on the sleeve 13. The bottom of the limiting rod 501 is set as an inclined chamfer. The top of the rotating rod 502 is rotatably installed on the bottom of the limiting rod 501. The torsion spring 503 is set at the rotation connection between the rotating rod 502 and the limiting rod 501. The bottom of the rotating rod 502 is connected to the support wheel 7.

[0036] In the actual testing process, the engine needs to be placed on a special tray for support. The tray has a certain height, and the collection box 2 needs to be lifted onto the tray. The sliding rod 5 is set as a limit rod 501 and a rotating rod 502. The rotation connection between the limit rod 501 and the rotating rod 502 is provided with a torsion spring 503. When moving the collection box 2, two rotating rods 502 first contact the tray to rotate. At this time, the body of the collection box 2 is already on the push plate, and it only needs to continue to be pushed to the middle of the tray. There is no need to manually lift the collection box 2 and then put it on the tray.

[0037] The joint between the limiting rod 501 and the rotating rod 502 is set to be inclined, and a torsion spring 503 is provided to apply thrust, and the thrust of the torsion spring 503 is large, so that the rotating rod 502 is not easy to rotate during the movement of the collection box 2, thereby ensuring the stability of the structural operation.

[0038] The collecting box 2 is also provided with a discharge port, which is convenient for pouring the oil into the refueling barrel. The collecting box 2 is also provided with an oil baffle 14 inside to block the oil when pouring the oil and prevent the oil from overflowing.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
