[0027] The orientation or position relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "radial", "circumferential", etc. are based on the orientation or position relationship shown in the drawings and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] See also Figure 1 The embodiment of the present application provides an oil level gauge, including a float 1, a pointer 2, a dial 3, a gear component 4 and a transmission component 5. The dial 3 has a float 1 and a pointer 2 on two opposite sides, and the pointer 2 is spaced apart from the dial 3; the gear component 4 includes a gear 41 and a rack 42, the gear 41 is rotatably connected to the dial 3, the pointer 2 is connected to the side of the gear 41 away from the dial 3, and the rack 42 is slidably connected to the dial 3 and meshes with the gear 41; the transmission component 5 is respectively connected to the float 1 and the rack 42, the float 1 is used to be placed in the oil barrel and move up and down with the oil level, and the transmission component 5 is used to drive the rack 42 to move.

[0032] In actual application, the buoy 1 is placed in the oil barrel. As the oil level rises, the buoy 1 moves upward and drives the transmission component 5 to move. The transmission component 5 drives the rack 42 to move. Since the rack 42 and the gear 41 are meshed, the movement of the rack 42 drives the gear 41 to rotate, and then drives the pointer 2 to rotate. The pointer 2 rotates on the dial 3. The dial 3 is usually provided with a scale to indicate the current oil level. Similarly, as the oil level drops, the buoy 1 will also move downward. At this time, the buoy 1 drives the transmission component 5 to move, and then drives the rack 42 to move. The movement of the rack 42 drives the gear 41 to rotate, and further drives the pointer 2 to rotate, showing the current oil level.

[0033] Compared with the prior art, the present application drives the transmission component 5 to move by the buoy 1 floating up and down with the oil level, and the transmission component 5 is connected to the gear component 4, and the gear component 4 drives the pointer 2 to rotate, thereby realizing the function of real-time display of the current oil level, and the pointer 2 is spaced apart from the dial 3 by the gear 41. The pointer 2 will not rub against the dial 3 when rotating, avoiding the influence of the friction force between the pointer 2 and the dial 3 on the numerical value, thereby making the oil level displayed by the pointer 2 more accurate.

[0034] Furthermore, the gear 41 can also be spaced apart from the dial 3, and the rack 42 can be spaced apart from the dial 3, which can effectively reduce the friction between the gear 41 and the rack 42 and the dial 3, and the resistance encountered by the pointer during rotation becomes smaller, so that it can more accurately follow the changes in the physical quantity of the buoy 1 and rotate, thereby more accurately indicating the measured value. At the same time, less friction means that the degree of wear between the pointer 2 and the dial 3 is reduced. During long-term use, excessive friction will cause the surface of the pointer 2 and the dial 3 to gradually wear, affecting the normal use of the device, and may even cause the pointer 2 to be inflexible or stuck, reducing the service life of the device. Reducing friction can effectively delay this wear, allowing the device to maintain good performance and accuracy for a longer period of time, reducing maintenance and replacement costs.

[0035] See also Figure 2 The transmission component 5 includes a push rod 51, a pressure plate 52 and a moving structure 53. One end of the push rod 51 is connected to the buoy 1, and the other end is slidably connected to the dial 3. The pressure plate 52 is movably connected to the dial 3 and is located between the push rod 51 and the dial 3. The moving structure 53 is respectively connected to the pressure plate 52 and the rack 42. The push rod 51 is used to drive the pressure plate 52 to slide relative to the dial 3 to drive the moving structure 53 to move.

[0036] In actual application, the buoy 1 is connected to the push rod 51. When the buoy 1 floats up and down with the oil level, the buoy 1 drives the push rod 51 to slide relative to the dial 3. The push rod 51 can be connected to the pressure plate 52, so the push rod 51 drives the pressure plate 52 to move, and the pressure plate 52 drives the moving structure 53 to move, and then the moving structure 53 drives the rack 42 to slide, and the rack 42 drives the gear 41 to rotate, and further drives the pointer 2 to rotate on the dial 3 to display the current oil level. This structure is simple to operate and easy to install. It can realize the transmission function without complex structural design, reducing the difficulty of device design.

[0037] It should be noted that the transmission component 5 is not limited to the above-mentioned structure. In other embodiments, the transmission component 5 may also adopt other structures, which is not limited in the present application.

[0038] See again Figure 2 and Figure 3The movable structure 53 includes a tilting rod 531, a guide rod 532, a first support member 533, a second support member 535 and a connecting structure 534. The first support member 533 and the second support member 535 are both connected to the dial 3. The tilting rod 531 includes a connecting end and a free end. The connecting end is rotatably connected to the second support member 535, and the free end is overlapped on the first support member 533. The pressure plate 52 is used to squeeze the free end; the guide rod 532 is slidably connected to the dial 3, and the connecting end is connected to the guide rod 532 to drive the guide rod 532 to slide. The connecting structure 534 is respectively connected to the guide rod 532 and the rack 42. The guide rod 532 is used to drive the connecting structure 534 to move, and the connecting structure 534 is used to drive the rack 42 to move.

[0039] In practical applications, the mobile structure 53 may include a tilting rod 531, a guide rod 532, a first support member 533, a second support member 535 and a connecting structure 534. The first support member 533 and the second support member 535 are respectively used to support the tilting rod 531. The connecting end of the tilting rod 531 is rotatably connected to the second support member 535, and its free end is overlapped on the first support member 533. Specifically, the first support member 533 should be located between the free end and the connecting end, which is conducive to pressing the pressure plate 52 toward the free end, so that the tilting rod 531 rotates around the fulcrum of the first support member 533. The connecting structure 534 moves when the guide rod 532 slides, and the connecting structure 534 drives the rack 42 to slide, thereby driving the gear 41 to rotate.

[0040] It should be noted that the movable structure 53 is not limited to the above-mentioned structure. In other embodiments, the movable structure 53 can also adopt other structures, and the present application does not limit this. For example, the movable structure 53 adopts a connecting rod mechanism, one end of the connecting rod is hinged to the top rod 51, and the other end is hinged to the rack 42. When the top rod 51 moves up and down, it can also drive the rack 42 to reciprocate linear motion.

[0041] See also Figure 4 The connecting structure 534 includes a lap rod 5341 and a slide rod 5342. The dial 3 is slidably connected to the slide rod 5342 on one side of the pointer 2. The rack 42 is connected to the slide rod 5342. The dial 3 is provided with a through groove 31 passing through its two opposite side surfaces. The lap rod 5341 passes through the through groove 31 and is respectively connected to the slide rod 5342 and the guide rod 532.

[0042] In practical applications, the connection structure 534 may include a lap rod 5341 and a slide rod 5342. One end of the lap rod 5341 overlaps the guide rod 532, and the other end overlaps the slide rod 5342. The lap rod 5341 can be rotatably connected in the through slot 31. When the tilting rod 531 drives the guide rod 532 to move, the guide rod 532 pulls the lap rod 5341 to move, and the lap rod 5341 drives the slide rod 5342 to slide, so that the rack 42 drives the gear 41 to rotate, and the pointer 2 rotates in the dial 3. In this structure, the lap rod 5341 can be overlapped with the guide rod 532 and the slide rod 5342 respectively. In this way, the lap rod 5341 is more convenient to install, and no extra connector is needed to connect it with the guide rod 532 or the slide rod 5342, thereby simplifying the device structure. It should be noted that the overlapping rod 5341 can also be detachably connected to the guide rod 532 and the sliding rod 5342 respectively, and this application does not limit this.

[0043] See also Figure 5 and Figure 6 The above-mentioned overlapping rod 5341 includes a first rod 53411 and a second rod 53412, the first rod 53411 and the second rod 53412 are connected at an angle, the guide rod 532 is provided with a first U-shaped groove 5321, the first rod 53411 is located in the first U-shaped groove 5321 and overlapped with the guide rod 532, the sliding rod 5342 is provided with a second U-shaped groove 53421, the second rod 53412 is located in the second U-shaped groove 53421 and overlapped with the sliding rod 5342.

[0044] In actual application, the guide rod 532 is provided with a first U-shaped groove 5321, and the first rod 53411 of the overlapping rod 5341 is inserted into the first U-shaped groove 5321 and overlapped on the guide rod 532. The sliding rod 5342 is provided with a second U-shaped groove 53421, and the second U-shaped groove 53421 is provided for the second rod 53412 to extend into and overlap on the sliding rod 5342. When the guide rod 532 drives the first rod 53411 to move, the first rod 53411 rotates in the direction close to the guide rod 532, thereby driving the second rod 53412 to rotate in the direction away from the guide rod 532, so that the second rod 53412 drives the sliding rod 5342 to move. The sliding rod 5342 is connected with a rack 42, so that the rack 42 drives the gear 41 to rotate, thereby realizing the rotation of the pointer 2.

[0045] See again Figure 4 The connecting structure 534 includes a guide rod 5343, which is connected to the dial 3, and the guide rods 5343 are slidably connected to the opposite ends of the sliding rod 5342.

[0046] In practical applications, the guide rod 5343 is used to ensure that the slide rod 5342 moves accurately along a specific straight line direction and plays a guiding role. The guide rod 5343 can provide precise guidance and positioning for the moving parts, thereby effectively reducing errors during the movement process.

[0047] See again Figure 4 The connecting structure 534 also includes a first elastic member 5344, which is sleeved on the guide rod 5343 and is used to push the sliding rod 5342 to slide.

[0048] In practical applications, the buoy 1 may be in the shape of a hollow ball, and the push rod 51 is arranged longitudinally. As the buoy 1 rises with the oil level, the buoy 1 drives the push rod 51 to rise and press the pressure plate 52, so that the pressure plate 52 can press the free end of the tilting rod 531 upward. When the tilting rod 531 rotates in a first direction around the fulcrum of the first support member 533, the connecting end of the tilting rod 531 rotates on the second support member 535 and drives the guide rod 532 to rotate in a second direction (such as Figure 6 The guide rod 532 drives the first rod 53411 of the lap rod 5341 to rotate along the third direction, the first rod 53411 drives the second rod 53412 to rotate along the third direction, and the second rod 53412 causes the movable slide rod 5342 to slide in a direction away from the gear 41 (such as Figure 5In the direction indicated by X2 in the figure), the slide bar 5342 drives the rack 42 to slide in the direction away from the gear 41. In this structure, when the oil level rises, the buoy 1 rises with the oil level, and the entire device moves under the action of buoyancy. When the oil level drops, the oil surface moves away from the buoy 1, and the entire device is no longer affected by external forces other than gravity. The entire device needs to rely on gravity to complete the movement when the oil level drops. This process is too slow and the efficiency is too low. Therefore, the present application sets a first elastic member 5344. When the oil level rises, the slide bar 5342 slides to compress the first elastic member 5344 to accumulate elastic potential energy. When the oil level drops, the buoy 1 drops with the oil level, and the push rod 51 drops accordingly, and no longer supports the pressure plate 52. The pressure plate 52 can move downward. At this time, the force of the pressure plate 52 on the tilting rod 531 disappears, so the guide rod 532 no longer pulls the lap rod 5341 to move, and the pulling force of the lap rod 5341 on the slide bar 5342 disappears. The first elastic member 5344 releases its elastic potential energy, and the first elastic member 5344 pushes the sliding rod 5342 to slide in the direction close to the gear 41, and the sliding rod 5342 drives the second rod 53412 to rotate in the opposite direction of the third direction, and the second rod 53412 drives the first rod 53411 to rotate in the opposite direction of the third direction, and then the first rod 53411 drives the guide rod 532 to slide in the opposite direction of the second direction, and the guide rod 532 drives the tilting rod 531 to rotate in the opposite direction of the first direction, so that the free end of the tilting rod 531 abuts against the pressure plate 52, and when the first elastic member 5344 releases its elastic potential energy, the sliding rod 5342 moves to drive the rack 42 to slide in the direction close to the gear 41, and then drives the gear 41 to rotate (the rotation direction is opposite to the rotation direction when the oil level rises), so that the pointer 2 displays the value after the oil level drops.

[0049] See also Figure 7 The transmission component 5 further includes a support frame 54, which is connected to the dial 3, and the push rod 51 passes through the support frame 54 and is slidably connected to the support frame 54. In practical applications, the support frame 54 is used to support and guide the push rod 51, and the support member is provided with a through hole, and the push rod 51 is slidably set in the through hole. The through hole limits the push rod 51 to limit the sliding direction of the push rod 51, ensuring that the push rod 51 moves accurately along a specific straight line direction, avoiding deviation in the moving direction of the push rod 51, and affecting the accurate measurement of the oil level gauge.

[0050] See again Figure 7 The transmission component 5 further includes a second elastic member 55 , and the second elastic member 55 elastically abuts between the support frame 54 and the push rod 51 .

[0051] In actual application, when the oil level drops, the second elastic member 55 can assist the push rod 51 to move away from the pressure plate 52, so that the push rod 51 can move away from the pressure plate 52 more quickly, and then release the elastic potential energy through the first elastic member 5344, the first elastic member 5344 pushes the slide rod 5342 to move, the slide rod 5342 drives the second rod 53412 to rotate, the second rod 53412 drives the first rod 53411 to rotate, and then the first rod 53411 drives the guide rod 532 to move, the guide rod 532 drives the tilting rod 531 to rotate, because the push rod 51 no longer supports the pressure plate 52, the pressure of the pressure plate 52 on the tilting rod 531 is also reduced, so it is more convenient for the guide rod 532 to drive the tilting rod 531 to rotate. Through the elastic action of the first elastic member 5344 and the second elastic member 55, during the process of oil level dropping, the time for the buoy 1 to descend to contact the oil surface can be accelerated, making the movement process of the entire device more convenient, and the pointer 2 can quickly and accurately display the current oil level. The second elastic member 55 is mainly used to improve stability. When the oil surface vibrates, the pointer 2 is relatively stable.

[0052] In this structure, the push rod 51 and the pressure plate 52 only need to be in contact and can achieve the above-mentioned function without being connected together. This arrangement saves the connection mechanism between the push rod 51 and the pressure plate 52 and simplifies the structure of the device.

[0053] It should be noted that both the first elastic member 5344 and the second elastic member 55 may be spring structures.

[0054] See again Figure 7 The top rod 51 includes a third rod 511 and a fourth rod 512 connected in sequence, the third rod 511 is connected to the buoy 1, the fourth rod 512 passes through the support frame 54 and is slidably connected to the support frame 54, and the second elastic member 55 is sleeved on the outer periphery of the fourth rod 512 and elastically abuts between the support frame 54 and the third rod 511.

[0055] In actual application, the push rod 51 includes a third rod 511 and a fourth rod 512. The diameter of the fourth rod 512 is smaller than that of the third rod 511, so a step portion is formed at the connection between the third rod 511 and the fourth rod 512, and the second elastic member 55 is respectively abutted between the step portion and the support frame 54. When the oil level rises, the push rod 51 moves toward the direction close to the pressure plate 52, and the third rod 511 squeezes the second elastic member 55, so that the second elastic member 55 is compressed to accumulate elastic potential energy; when the oil level drops, the second elastic member 55 releases the elastic potential energy and pushes the push rod 51 away from the pressure plate 52, so that the buoy 1 can quickly contact the oil surface.

[0056] In a specific application, when the oil level rises, the buoyancy of the oil pushes the buoy 1 to rise, and the buoy 1 drives the push rod 51 to rise. At the same time, the push rod 51 squeezes the second elastic member 55. The push rod 51 rises and pushes the pressure plate 52 to press against the tilting rod 531. The free end of the tilting rod 531 rotates along the first direction around the fulcrum of the first support member 533, thereby driving the connecting end of the tilting rod 531 to rotate around the second support member 535 along the first direction. The connecting end drives the guide rod 532 to slide along the second direction, and the guide rod 532 pulls the second elastic member 551. The first rod 53411 rotates along the third direction, thereby driving the second rod 53412 of the overlapping rod 5341 to rotate along the third direction. The second rod 53412 drives the sliding rod 5342 to slide in the direction of squeezing the first elastic member 5344 (that is, in the direction away from the gear 41). The sliding rod 5342 drives the rack 42 to slide along the fourth direction, thereby causing the rack 42 to drive the gear 41 to rotate along the fifth direction, and further drives the pointer 2 to rotate along the fifth direction, so that it indicates the scale value corresponding to the current oil level.

[0057] When the oil level drops, the oil surface moves away from the buoy 1. At this time, the second elastic member 55 releases its elastic potential energy, pushing the push rod 51 away from the pressure plate 52, so that the buoy 1 contacts the oil surface again. At the same time, the first elastic member 5344 releases its elastic potential energy. The first elastic member 5344 pushes the slide bar 5342 to move in the direction close to the gear 41. On the one hand, the slide bar 5342 drives the rack 42 to slide in the opposite direction of the fourth direction, so that it drives the gear 41 to rotate in the opposite direction of the fifth direction, and then drives the pointer 2 to rotate in the opposite direction of the fifth direction. On the other hand, the slide bar 5342 pulls the second rod 53412 to rotate in the opposite direction of the third direction. The rod 53412 drives the first rod 53411 to rotate in the opposite direction of the third direction, so that the first rod 53411 drives the guide rod 532 to slide in the opposite direction of the second direction, and the guide rod 532 further drives the tilting rod 531 to rotate in the opposite direction of the first direction. The tilting rod 531 pushes the pressure plate 52 to slide in the direction close to the push rod 51 until the pressure plate 52 contacts or resists the push rod 51. At this time, when the elastic force of the first elastic member 5344 and the second elastic member 55 is equal to the buoyancy of the buoy 1, the entire device is balanced, and the pointer 2 no longer rotates. The scale indicated by the pointer 2 is the current oil level scale.

[0058] Different from the prior art, the embodiment of the present application provides an oil level gauge, including a float 1, a pointer 2, a dial 3, a gear component 4 and a transmission component 5. The dial 3 has a float 1 and a pointer 2 on two opposite sides, and the pointer 2 is spaced apart from the dial 3; the gear component 4 includes a gear 41 and a rack 42, the gear 41 is rotatably connected to the dial 3, the pointer 2 is connected to the side of the gear 41 away from the dial 3, and the rack 42 is slidably connected to the dial 3 and meshes with the gear 41; the transmission component 5 is respectively connected to the float 1 and the rack 42, the float 1 is used to be placed in the oil barrel and move up and down with the oil level, and the transmission component 5 is used to drive the rack 42 to move. Compared with the prior art, the present application drives the transmission component 5 to move by the buoy 1 floating up and down with the oil level, and the transmission component 5 is connected to the gear component 4, and the gear component 4 drives the pointer 2 to move, so as to realize the function of displaying the current oil level in real time, and the pointer 2 is spaced apart from the dial 3 through the gear 41, and the pointer 2 will not rub against the dial 3 when rotating, which reduces the influence of friction on the value, so that the oil level displayed by the pointer 2 is more accurate. At the same time, less friction means that the degree of wear between the pointer 2 and the dial 3 is reduced. During long-term use, excessive friction will cause the surface of the pointer 2 and the dial 3 to gradually wear, affecting the normal use of the device, and may even cause the pointer 2 to be inflexible or stuck, reducing the service life of the device. Reducing friction can effectively delay this wear, so that the device can maintain good performance and accuracy for a longer period of time, reducing maintenance and replacement costs.

[0059] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
