Description

Technical Field

[0001] This utility model relates to the field of engine maintenance technology, and more specifically, to an engine oil replacement device. Background Technology

[0002] During car engine maintenance, regular engine fluid changes are necessary, with engine oil being the most common. When changing engine oil, the drain plug on the oil pan needs to be opened from under the car to allow the oil to drain naturally under gravity. Due to the high ground clearance of the car, either a drain chute or a lift is used to raise the car. In areas with limited space, a car-specific ramp is needed to allow the front wheels to drive onto the ramp, lifting the front of the car for draining. Most existing ramps consist of two welded iron frames, which are bulky and inconvenient to transport. Furthermore, the front wheels are not restrained when the car is parked on the ramp, posing a safety hazard. Additionally, the lack of connection between the two ramps makes the entire device unstable. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an engine oil replacement device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an engine oil changing device, comprising two ramp blocks and two support blocks, wherein the ramp blocks and support blocks are arranged in a one-to-one correspondence, and the corresponding ramp blocks and support blocks are connected together by a connecting mechanism. The support blocks are hollow inside, and a blocking block is fixed on the top surface of the support block away from the ramp blocks. A telescopic groove is formed through the top surface of the support block near the ramp blocks, and a telescopic block is inserted into the telescopic groove. A driving mechanism is provided inside the support block, and the driving mechanism is used to drive the telescopic block to perform reciprocating telescopic movement within the telescopic groove. Each pair of support blocks is connected to each other by several connecting components.

[0005] As a preferred technical solution of this utility model, the connecting mechanism includes a slot and a plug-in block. The slot is opened on one end of the ramp block, and the plug-in block is fixed on the side of the bearing block near the ramp block. Both the slot and the plug-in block are T-shaped, and the plug-in block is inserted into the slot.

[0006] As a preferred technical solution of this utility model, the driving mechanism includes a threaded sleeve, a screw, a first bevel gear, a second bevel gear, a rotating shaft, and a crank handle. The threaded sleeve is fixed on the telescopic block. The screw is threadedly installed on the internal thread of the threaded sleeve. The two ends of the screw are rotatably connected to the inner wall of the bearing block. The first bevel gear is coaxially fixed on the screw. A second bevel gear is provided on one side of the first bevel gear and meshes with it. The rotating shaft is coaxially fixed on the second bevel gear.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 5 As shown, this utility model provides an engine oil changing device, including two ramp blocks 1 and two support blocks 2. The ramp blocks 1 and support blocks 2 are arranged in a one-to-one correspondence and are connected together by a connecting mechanism. The support blocks 2 are hollow inside. A blocking block 5 is fixed on the top surface of the support block 2 away from the ramp block 1. A telescopic groove 6 is opened through the top surface of the support block 2 near the ramp block 1. A telescopic block 7 is inserted into the telescopic groove 6. A driving mechanism is provided inside the support block 2. The driving mechanism is used to drive the telescopic block 7 to reciprocate and extend within the telescopic groove 6. Each pair of support blocks 2 are connected by several connecting components on their sides.

[0020] The connecting mechanism includes a slot 3 and a plug block 4. The slot 3 is located on one end of the ramp block 1, and the plug block 4 is fixed to the side of the support block 2 near the ramp block 1. Both the slot 3 and the plug block 4 are T-shaped, and the plug block 4 is inserted into the slot 3. The ramp block 1 and the support block 2 can be quickly assembled by using the plug block 4 and the slot 3.

[0021] The drive mechanism includes a threaded sleeve 8, a screw 9, a first bevel gear 10, a second bevel gear 11, a rotating shaft 12, and a crank handle 13. The threaded sleeve 8 is fixed on the telescopic block 7. The screw 9 is installed on the internal thread of the threaded sleeve 8. The two ends of the screw 9 are rotatably connected to the inner wall of the bearing block 2. The first bevel gear 10 is coaxially fixed on the screw 9. The second bevel gear 11 is provided on one side of the first bevel gear 10 and meshes with it. The rotating shaft 12 is coaxially fixed on the second bevel gear 11. The rotating shaft 12 is rotatably connected to the bearing block 2. One end of the rotating shaft 12 passes through the inner wall of the bearing block 2 and is fixed to the crank handle 13. After the vehicle is driven to the appropriate position on the support block 2, the operator turns the crank handle 13 to drive the rotating shaft 12 to rotate. The rotating shaft 12 drives the first bevel gear 10 to rotate through the second bevel gear 11. The second bevel gear 11 drives the screw 9 to rotate. The screw 9 drives the threaded sleeve 8 to lift the telescopic block 7, so that the telescopic block 7 cooperates with the blocking block 5 to limit the tire and prevent the tire from moving during the oil change.

[0022] The connecting assembly includes a crossbar 17, locking blocks 20, and locking seats 18. A locking block 20 is fixed to each end of the crossbar 17, and a locking seat 18 is fitted onto each locking block 20. The locking seats 18 are fixedly connected to two bearing blocks 2. (See attached diagram) Figure 3 As shown, a vertical groove is formed along the upper edge of the card holder 18, and a horizontal groove is formed along the upper edge of the side of the card holder 18. The horizontal groove communicates with the vertical groove. After the card block 20 is inserted into the vertical groove, the horizontal bar 17 is inserted into the horizontal groove, so that the card holder 18 can hold the horizontal bar 17. By setting this connecting component, the two bearing blocks 2 can be connected into a whole, making it more stable when carrying a vehicle. At the same time, the horizontal bar 17 of this connecting component is a quick-release design, making the disassembly and assembly of the entire device more convenient.

[0023] The blocking block 5 has a cavity inside, and an airbag 14 is fixed inside the blocking block 5, communicating with the cavity. An air outlet pipe 15 is fixed outside the blocking block 5, communicating with the inner cavity, and a whistle 16 is installed on the air outlet pipe 15. The airbag 14 is hemispherical. When a vehicle drives onto the support block 2, the airbag 14 is provided so that the driver can know the position of the car tire on the support block 2 in time. When the tire compresses the airbag 14, the airbag 14 squeezes the gas inside into the cavity. The gas in the cavity is ejected through the air outlet pipe 15. When the ejected airflow is blown out by the whistle 16, it will make a whistling sound to remind the driver to reduce the throttle in time, so as to avoid the driver's excessive throttle causing the tire to hit the blocking block 5 excessively, which could cause the support block 2 to shift.

[0024] When using this invention, if it is necessary to change the oil in a vehicle engine, the ramp block 1 and the support block 2 are connected as shown in the attached diagram. Figure 1-2After assembly, the vehicle is driven onto the support block 2 via ramp 1. Once the front wheels of the vehicle are against the blocking block 5, the vehicle is stopped. Then, the operator operates the drive mechanism to raise the telescopic block 7, so that the telescopic block 7 and the blocking block 5 together limit the front wheels of the vehicle on the support block 2. This can prevent the wheels from moving accidentally during the oil change process. At the same time, the ramp 1 and the support block 2 can be quickly disassembled and assembled through the connecting mechanism, and the two support blocks 2 can be fixedly connected by the connecting components, which further improves the stability of the entire device.
