Description

Technical Field

[0001] This utility model relates to the field of oil level sensors, specifically an oil level sensor that is easy to clean. Background Technology

[0002] Fuel level sensors include float-type sensors, resistive sensors, and reed switch sensors. Due to contamination of fuel in the fuel tank, oil and dirt can cause problems such as poor contact and malfunction of the gauge, making it impossible for the sensor to read accurately. Therefore, a fuel level sensor that is easy to clean is needed.

[0003] Existing fuel level sensors are typically fixed using flanges and bolts. When cleaning and maintaining them, workers need to disassemble each bolt individually, which not only reduces the maintenance efficiency of the fuel level sensor, but also easily causes the bolt threads to strip due to prolonged disassembly, thus affecting the stability of the fuel level sensor. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem that existing oil level sensors are usually fixed with flanges and bolts, requiring workers to disassemble each bolt individually for cleaning and maintenance, which not only reduces the maintenance efficiency of the oil level sensor, but also easily causes bolt stripping due to long-term disassembly, thus affecting the stability of the oil level sensor, this utility model proposes an oil level sensor that is easy to clean.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an oil level sensor that is easy to clean, including an oil level sensor body, a flange is movably sleeved on the surface of the oil level sensor body, and two positioning mechanisms are provided on the top of the flange;

[0006] The positioning mechanism includes a positioning shell, which is fixedly installed on the surface of a flange. A positioning rod is rotatably connected to the inner cavity of the positioning shell. A limiting rod and two gears are fixedly sleeved on the surface of the positioning rod. A clamping block is fixedly connected to the top of the limiting rod, and the bottom of the clamping block contacts the top of the oil level sensor body. Both ends of the positioning rod penetrate the positioning shell and are fixedly connected to a positioning cover. A torsion spring is provided in the inner cavity of the positioning cover. The torsion spring is sleeved on the outer surface of the positioning rod. One end of the torsion spring is fixedly connected to the inner wall of the positioning cover, and the other end of the torsion spring is fixedly connected to the surface of the positioning shell.

[0007] Preferably, the inner cavity of the positioning shell is slidably connected to a limiting plate, and two insert blocks are fixedly connected to one side of the limiting plate. One side of the insert blocks meshes with the teeth on the surface of the gear. A positioning frame is fixedly connected to the top of the limiting plate, and an insert rod is rotatably connected to the inner cavity of the positioning frame through a shaft pin. A perforated plate that cooperates with the insert rod is fixedly connected to the top of the positioning shell.

[0008] Preferably, both ends of the limiting plate are fixedly connected to limiting blocks, and one side of the limiting block is in contact with the surface of the positioning shell.

[0009] By setting limit blocks, the limit plate can be limited, thereby improving the stability of the lateral movement of the limit plate.

[0010] Preferably, a slide rod is fixedly connected to one side of the positioning frame, and one end of the slide rod extends through to the outside of the positioning shell.

[0011] Preferably, a spring is provided on one side of the positioning frame, the spring is sleeved on the outer surface of the slide rod, one end of the spring is fixedly connected to one side of the positioning frame, and the other end of the spring is fixedly connected to the inner wall of the positioning shell.

[0012] By incorporating a spring, the reaction force of the spring pushes the positioning frame and the limiting plate to move laterally, enabling rapid positioning of the gear and thus improving the positioning efficiency of the clamping block on the main body of the oil quantity sensor.

[0013] Preferably, a first sealing ring is fixedly installed in the inner cavity of the flange, and a second sealing ring is fixedly installed at the bottom of the flange. The surface of the second sealing ring is provided with a through hole for use with the flange.

[0014] Preferably, a limiting ring is fixedly connected to the bottom of the flange, and the limiting ring is sleeved on the outside of the second sealing ring.

[0015] The advantages of this utility model are:

[0016] This invention, by setting a positioning mechanism, can clamp and position the main body of the oil level sensor. By rotating the angle of the limiting rod, the clamping block can be disassembled from the surface of the main body of the oil level sensor, thereby improving the efficiency of cleaning and maintaining the main body of the oil level sensor. It solves the problem that existing oil level sensors are usually fixed with flanges and bolts, and when cleaning and maintaining them, workers need to disassemble each bolt one by one. This not only reduces the maintenance efficiency of the oil level sensor, but also easily causes the bolt threads to strip after long-term disassembly, thus affecting the stability of the oil level sensor.

[0024] 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 scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses an oil level sensor that is easy to clean. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An easy-to-clean oil level sensor includes an oil level sensor body 1, a flange 2 movably fitted on the surface of the oil level sensor body 1, and two positioning mechanisms 3 provided on the top of the flange 2.

[0027] The positioning mechanism 3 includes a positioning shell 301, which is fixedly installed on the surface of the flange 2. A positioning rod 302 is rotatably connected to the inner cavity of the positioning shell 301. A limiting rod 303 and two gears 304 are respectively fixedly sleeved on the surface of the positioning rod 302. A clamping block 305 is fixedly connected to the top of the limiting rod 303, and the bottom of the clamping block 305 contacts the top of the oil quantity sensor body 1. Both ends of the positioning rod 302 penetrate the positioning shell 301 and are fixedly connected to a positioning cover 306. The inner cavity of the positioning cover 306 is provided with... A torsion spring 307 is provided, which is sleeved on the outer surface of the positioning rod 302. One end of the torsion spring 307 is fixedly connected to the inner wall of the positioning cover 306, and the other end of the torsion spring 307 is fixedly connected to the surface of the positioning shell 301. By setting the positioning mechanism 3, the oil level sensor body 1 can be clamped and positioned, and by rotating the angle of the limiting rod 303, the clamping block 305 can be disengaged from the surface of the oil level sensor body 1, thereby improving the efficiency of cleaning and maintaining the oil level sensor body 1 by the staff.

[0028] Reference Figure 4 and Figure 5 The inner cavity of the positioning shell 301 is slidably connected to a limiting plate 308. Two inserts 309 are fixedly connected to one side of the limiting plate 308. One side of the inserts 309 meshes with the teeth on the surface of the gear 304. A positioning frame 310 is fixedly connected to the top of the limiting plate 308. An insert rod 311 is rotatably connected to the inner cavity of the positioning frame 310 through a shaft pin. A perforated plate 312 that cooperates with the insert rod 311 is fixedly connected to the top of the positioning shell 301. By setting the limiting plate 308, inserts 309, positioning frame 310, insert rod 311 and perforated plate 312 to cooperate, when disassembling the oil level sensor body 1, the positioning frame 310 is pulled laterally. After the positioning frame 310 drives the limiting plate 308 and inserts 309 to move laterally, the operator rotates the insert rod 311 to insert it into the inner cavity of the perforated plate 312. Then, the angle of the limiting rod 303 can be rotated to remove the oil level sensor body 1.

[0029] Reference Figure 4 and Figure 5 Both ends of the limiting plate 308 are fixedly connected to limiting blocks 313, and one side of the limiting block 313 is in contact with the surface of the positioning shell 301. By setting the limiting block 313, the limiting plate 308 can be limited, thereby improving the stability of the lateral movement of the limiting plate 308.

[0030] Reference Figure 4 and Figure 5 A slide rod 314 is fixedly connected to one side of the positioning frame 310, and one end of the slide rod 314 extends through to the outside of the positioning shell 301. By setting the slide rod 314, the positioning frame 310 can be limited, thereby improving the stability of the lateral movement of the positioning frame 310.

[0031] Reference Figure 5A spring 315 is provided on one side of the positioning frame 310. The spring 315 is sleeved on the outer surface of the slide rod 314. One end of the spring 315 is fixedly connected to one side of the positioning frame 310, and the other end of the spring 315 is fixedly connected to the inner wall of the positioning shell 301. By setting the spring 315, the reaction force of the spring 315 pushes the positioning frame 310 and the limiting plate 308 to move laterally, which can quickly position the gear 304, thereby improving the positioning efficiency of the clamping block 305 on the oil quantity sensor body 1.

[0032] Reference Figure 2 and Figure 3 A first sealing ring 4 is fixedly installed in the inner cavity of the flange 2, and a second sealing ring 5 is fixedly installed at the bottom of the flange 2. The surface of the second sealing ring 5 has a through hole 6 that is used to cooperate with the flange 2. By setting the first sealing ring 4 and the second sealing ring 5 to cooperate, the sealing between the flange 2 and the oil level sensor body 1 can be improved, and leakage at the joint can be avoided.

[0033] Reference Figure 3 A limiting ring 7 is fixedly connected to the bottom of the flange 2, and the limiting ring 7 is sleeved on the outside of the second sealing ring 5. By setting the limiting ring 7, the second sealing ring 5 can be limited, thereby improving the stability of the second sealing ring 5 in use.

[0034] Working principle: During use, the operator pulls the positioning frame 310 laterally. As the positioning frame 310 moves laterally, it causes the limiting plate 308 and the insert block 309 to move laterally as well. After the insert block 309 disengages from the gear 304, the limiting of the gear 304 is released. Then, the operator rotates the insert rod 311 to insert it into the cavity of the hole plate 312. After both positioning frames 310 are in their limiting positions, the operator rotates the two limiting rods 303. As the limiting rods 303 rotate, they cause the positioning rod 302 to rotate. 2. When rotating, the two positioning covers 306 and the two gears 304 will rotate. When the positioning cover 306 rotates, it will squeeze the torsion spring 307. When the limit rod 303 rotates to the specified angle, the clamping block 305 will disengage from the surface of the oil quantity sensor body 1. At this time, the oil quantity sensor body 1 can be pulled upward to disassemble it. By snapping the oil quantity sensor body 1 into the inside of the flange 2, not only can the disassembly and cleaning efficiency of the oil quantity sensor body 1 be improved, but also the stability of the oil quantity sensor body 1 during installation and use can be improved.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
