[0002] The primary function of an oil extraction machine is to extract oil. It is a crucial piece of equipment in oil extraction, using its working principle to pump oil from underground to the surface. Oil extraction machines have become a hallmark structure of oil fields.

[0003] In reality, most people have never seen an oil extraction machine. Therefore, there is a need for an oil extraction machine model or toy as equipment for safety, technical education, and scientific research, or as a toy or ornament. For example, patent applications "200520026998.9" ("Dynamic Simulation Model of Oil Extraction") and "201330152887.2" ("Oil Extraction Machine Model") both directly place the motor assembly at the rear, using a belt to drive the oscillation of the furnace head.

[0007] A balancing component is provided at each end of the connecting shaft, and a connecting rod is rotatably connected to both sides of the rear end of the oil extraction component. The bottom of each connecting rod is rotatably connected to the middle of a balancing component.

[0008] When the motor assembly drives the gear and coupling to rotate, it synchronously drives the balance components on both sides to rotate, and drives the connecting rod to make the oil extraction component swing back and forth around the support.

[0009] A piston is also movably mounted on the housing. The rear end of the piston extends outside the housing, and the front end of the piston is connected to the gear via a piston rod. When the gear rotates, it drives the piston to move back and forth reciprocally via the piston rod.

[0010] In the above technical solution, the gear is provided with an intermediate shaft, the middle part of the connecting shaft is inserted into the intermediate shaft, and the connecting shaft and the intermediate shaft are not coaxially arranged;

[0013] The rear end of the piston rod is inserted between the two gear plates and rotatably mounted on the intermediate shaft.

[0014] In the above technical solution, the balancing component includes a connecting plate and a balancing block. The balancing block is disposed at one end of the connecting plate, the other end of the connecting plate is connected to the end of the connecting shaft, and the bottom of the connecting rod is rotatably connected to the middle of the connecting plate.

[0015] In the above technical solution, the oil extraction component includes a walking beam and a donkey head. The middle part of the walking beam is rotatably connected to the top of the support. The donkey head is located at the front end of the walking beam. The tops of the two connecting rods are rotatably connected to the rear end of the walking beam.

[0016] And / or, the rear end of the walking beam is provided with a rear end connecting rod, and the tops of the two connecting rods are respectively rotatably connected to the two ends of the rear end connecting rod.

[0017] In the above technical solution, the worm gear is located on the front side of the gear and meshes with the gear, and the motor assembly drives the worm gear to rotate.

[0018] In the above technical solution, a front gear is provided on the outer front end of the housing, and the front gear is rotatably connected to the housing via a front coupling shaft; a crown gear is provided at the rear end of the front coupling shaft, and a flat gear that meshes with the crown gear is also provided on the outer surface of the worm.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0036] Example 1: See Figure 1-7 As shown, an oil extraction machine model toy includes a base 1, a bracket 2 mounted on the base 1, an oil extraction component 3, and a drive unit 4. The oil extraction component 3 is rotatably mounted on the top of the bracket 2 at its center. The drive unit 4 is configured to drive the oil extraction component 3 to swing around the bracket 2. The oil extraction component is an oil extraction component model.

[0037] The drive unit 4 includes a housing 41, a motor assembly 42, a gear 43, and a coupling 44 installed inside the housing 41. The housing 41 is installed on the base 1. The gear 43 is rotatably connected to the housing 41 via the coupling 44. The two ends of the coupling 44 pass through the housing 41 and are respectively located on the outside of the two sides of the housing 41. The motor assembly 42 is provided with a worm gear 45 that meshes with the gear 43. The motor assembly 42 and the worm gear 45 drive the gear 43 and the coupling 44 to rotate relative to the housing 41.

[0038] A balancing component 31 is provided at each end of the connecting shaft 44, and a connecting rod 32 is rotatably connected to both sides of the rear end of the oil extraction component 3. The bottom of each connecting rod 32 is rotatably connected to the middle of a balancing component 31.

[0039] When the motor assembly 42 drives the gear 43 and the connecting shaft 44 to rotate, it synchronously drives the balance components 31 on both sides to rotate, and drives the connecting rod 32 to drive the oil production component 3 to swing back and forth around the support 2.

[0040] A piston 46 is also movably mounted on the housing 41. The rear end of the piston 46 extends out of the housing 41. The front end of the piston 46 is connected to the gear 43 via a piston rod 47. When the gear 43 rotates, the piston 46 is driven to move back and forth relative to the housing 41 via the piston rod 47.

[0041] In this embodiment, the oil extraction component 3 includes a walking beam 33 and a donkey head 34. The middle part of the walking beam 33 is rotatably connected to the top of the support 2, the donkey head 34 is disposed at the front end of the walking beam 33, and the tops of the two connecting rods 32 are rotatably connected to the rear end of the walking beam 33. In this embodiment, the bottom of the worm gear is connected to the output shaft at the top of the motor assembly, and the top of the worm gear is rotatably connected to the housing. The worm gear is driven to rotate by the motor assembly. Due to the meshing of the worm gear and the gear, the gear will rotate in one direction. The gear is fixedly connected to the connecting shaft, and the connecting shaft is rotatably connected to the housing. Therefore, when the gear rotates, it will simultaneously drive the connecting shaft to rotate. During the rotation of the connecting shaft, it will simultaneously drive the balancing component to rotate. Preferably, one end of the balancing component is connected to the end of the connecting shaft, and the other end is set away from the connecting shaft. The bottom of the connecting rod is rotatably connected to the middle of the balancing component. The rotatable connection between the connecting rod and the balancing component is located on the side of the connecting shaft. Therefore, when the connecting shaft drives the balancing component to rotate, the rotatable connection between the connecting rod and the balancing component will move in a circular trajectory around the connecting shaft, thereby driving the bottom and top of the connecting rod to move up and down. Since the top of the connecting rod is rotatably connected to the rear end of the walking beam, it will push the walking beam to swing back and forth around the support, causing the furnace head to swing up and down around the support, realizing the swing of the furnace head in the oil production machine model. In this way, the simulation motion of the oil production machine model can be realized. Additionally, a piston is included, connected to a gear via a piston rod. As the gear rotates, it drives the piston to move back and forth along the casing. This design creates a model resembling an engine structure, mimicking the movement of oil extraction components. This enhances the aesthetics and interactivity, while also providing a better educational effect. Furthermore, the motor assembly is located inside the casing and not exposed. When the oil rig model is being displayed, viewers are unaware that a motor is used to drive the oil extraction components; they only see the movement of the piston, creating the illusion of engine operation and increasing interactivity. Of course, a chimney model can also be added to the top of the casing, transforming the entire casing into an engine model with a chimney.

[0042] The base can have a pre-installed battery compartment for installing batteries that power the motor assembly. Alternatively, a USB, Type-C, or other power port, or a power cable, can be provided on the base to power the motor assembly from an external power source. Furthermore, a control switch can be pre-installed on the base, housing, or other location to control the operation of the motor assembly.

[0043] See Figure 5-7 As shown, the gear 43 is provided with an intermediate shaft 430, the middle part of the connecting shaft 44 is inserted into the intermediate shaft 430, and the connecting shaft 44 and the intermediate shaft 430 are not coaxially arranged.

[0044] The rear end of the piston rod 47 is rotatably sleeved on the intermediate shaft 430.

[0045] The gear 43 includes two gear plates 431, at least one of which meshes with the worm 45. The two ends of the intermediate shaft 430 are respectively connected to the two gear plates 431. The middle part of the connecting shaft 44 is connected to the intermediate shaft 430 and the two gear plates 431. In this embodiment, both gear plates mesh with the worm. At the same time, the intermediate shaft and the connecting shaft cannot rotate relative to each other. When the connecting shaft rotates, the intermediate shaft will follow the connecting shaft to rotate, so that the axis of the intermediate shaft moves in a circular trajectory relative to the axis of the connecting shaft.

[0046] The rear end of the piston rod 47 is inserted between the two gear plates 431 and rotatably mounted on the intermediate shaft 430.

[0047] In this embodiment, the gear is provided with an intermediate shaft that is not aligned with the connecting shaft. The rear end of the piston rod is rotatably mounted on the intermediate shaft. Preferably, the rear end of the piston rod has a clearance hole through which the piston rod is mounted on the intermediate shaft. The diameter of the clearance hole matches the diameter of the intermediate shaft. In this way, when the gear rotates, the axis of the intermediate shaft will move in a circular trajectory around the axis of the connecting shaft, thereby driving the rear end of the piston rod to rotate around the intermediate shaft. At the same time, the front end of the piston rod is rotatably connected to the rear end of the piston, thereby driving the piston to move back and forth. In this embodiment, the gear uses two gear plates, and the piston rod is located between the two gear plates. Two fins can also be used to restrict the gear plates from detaching from the intermediate shaft.

[0048] In this invention, apart from the motor assembly, the other parts of the oil drilling machine model toy can all be made of plastic, plastic or wood materials. They are assembled by a modular assembly method, which makes them more playable and more active.

[0049] See Figure 1-4 As shown, the balancing component 31 includes a connecting plate 35 and a balancing block 36. The balancing block 36 is disposed at one end of the connecting plate 35, and the other end of the connecting plate 35 is connected to the end of the connecting shaft 44. The bottom of the connecting rod 32 is rotatably connected to the middle part of the connecting plate 35.

[0050] Furthermore, in this embodiment, the bottom of the connecting rod has an elastic buckle, and the middle of the connecting plate has a mounting hole. The connecting rod is connected to the mounting hole via the elastic buckle. The elastic buckle is a U-shaped structure that opens towards the housing, and it directly snaps into the mounting hole, enabling quick assembly and easy disassembly.

[0051] In this embodiment, the housing is located directly below the rear end of the walking beam, on the rear side of the support, and is positioned between two connecting rods. The connecting rods adopt an L-shaped structure, including an upper rod, a middle rod, and a lower rod. The middle rod is perpendicular to the upper and lower rods, and its two ends are connected to the bottom of the upper rod and the top of the lower rod, respectively. The upper rod has an inwardly extending upper connector on the inner side of its top, which is rotatably connected to the rear end of the walking beam. The lower rod has an inwardly extending lower connector (elastic buckle) on the inner side of its bottom, which is rotatably connected to the middle of the connecting plate.

[0052] See Figure 1 , 2 As shown in Figure 4, the rear end of the walking beam 33 is provided with a rear end connecting rod 37, and the tops of the two connecting rods 32 are respectively rotatably connected to the two ends of the rear end connecting rod 37. The middle part of the rear end connecting rod is connected to the rear end of the walking beam, and its two ends and the tops of the connecting rods on both sides are rotatably connected. By setting the rear end connecting rod, it is possible to simultaneously rotatably connect the top of the drying connecting rod and the rear end of the walking beam.

[0053] See Figure 4-7 As shown, the worm gear 45 is disposed on the front side of the gear 43 and meshes with the gear 43. The motor assembly 42 drives the worm gear 45 to rotate. In this embodiment, the worm gear is arranged vertically, and the coupling is arranged horizontally. The worm gear is disposed on the front side of the gear, and the piston is disposed on the rear side of the gear. When the motor assembly drives the worm gear to rotate, it does not affect the forward and backward movement of the piston.

[0054] See Figure 4-7 As shown, a front gear 48 is provided on the front exterior of the housing 41, and the front gear 48 is rotatably connected to the housing 41 via a front connecting shaft 49; a crown gear 410 is provided at the rear end of the front connecting shaft 49, and a flat gear 411 that meshes with the crown gear 410 is also provided on the outer surface of the worm 45.

[0055] In this embodiment, a front gear is pre-installed on the exterior of the front end of the housing. This front gear meshes with a spur gear on the handle via a front coupling and a crown gear, thereby driving the front gear to rotate. The spur gear is positioned near the bottom of the worm gear, below the rear end of the worm gear, and does not contact the worm gear. In this design, when the component is driven to reciprocate, the front gear also rotates outside the housing, showcasing a strong mechanical aesthetic. Furthermore, the inclusion of the front gear allows for future modifications. If additional functions are added to the oil rig model toy, a functional component can be added to the base or bracket to mesh or connect with the front gear, facilitating the addition of other DIY components.

[0056] refer to Figure 1-3 As shown, a first pulley 440 is also provided on the outer surface of the connecting shaft 44. The first pulley 440 is disposed between the balance component 31 and the housing 41 on one side. A second pulley 441 is rotatably mounted on the bracket. A belt 442 is also provided, which is wound around the first pulley 440 and the second pulley 441.

[0057] The bracket 2 is also equipped with a second gear 21, which is rotatably connected to the bracket 2 via a second connecting shaft 22, and one end of the second connecting shaft 22 is connected to the middle of the second pulley 441. When the second pulley rotates, it will simultaneously drive the second gear to rotate via the second connecting shaft.

[0058] The arrangement of the first pulley, second pulley, belt, and second gear enhances the mechanical aesthetics of the entire oil rig model toy. Furthermore, if the model toy is subsequently further developed to include additional functions, such as adding functional components to the base or support, these components can mesh or connect with the second gear, or replace the second pulley by directly connecting the first pulley and functional components via the belt. This facilitates the addition of other DIY parts, increasing the toy's playability and expandability.
