Description

Technical Field

[0001] The utility model relates to the technical field of measuring engine oil, in particular to a spiral structure oil dipstick. Background Art

[0002] In the process of implementing the present invention, the inventors discovered that the prior art has at least the following problems:

[0003] An engine oil dipstick is typically used to measure the oil level, indirectly revealing the amount of oil in the oil pan. The dipstick and its guide tube form the oil level detection subsystem within the lubrication system. JP-A-Heisei 8-247822 discloses an oil dipstick (not specifically shown) consisting of three parts: a handle, a body, and a measuring section. Specifically, the measuring section has an elongated, flat plate shape, with upper and lower oil level markings located above and below it, indicating the appropriate range of engine oil levels.

[0004] Typically, the dipstick is inserted into a conduit connected to the cylinder oil pan, so that only the measuring portion of the dipstick is immersed in the oil in the pan. During measurement and inspection, the dipstick is removed from the conduit and the engine oil adhering to the measuring portion is inspected to measure and inspect the amount and oxidation state of the engine oil in the pan. The results of these inspections determine the intervals for refilling and changing the engine oil.

[0005] As for traditional oil dipsticks, the dipstick body is generally made of flat steel and is not easy to bend. In the engine or other functional equipment, the oil circuit is more curved. For the traditional flat steel type oil dipstick, it is not easy to bend when passing through, so the passability is not smooth. Usually, the oil dipstick pipeline designed by engineers has complex bends, which makes it difficult to insert and remove the oil dipstick. Utility Model Content

[0006] The utility model aims to provide a spiral structure oil dipstick which is detachable and has high installation stability and can smoothly pass through a complicated and bendy oil dipstick pipeline.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A spiral structure oil dipstick includes a dipstick handle, a flat steel dipstick body, and an oil-measuring reticulated steel strip fixed to the flat steel dipstick body. The dipstick handle and the flat steel dipstick body are plug-in connected, and a plug-in fastener is provided between the dipstick handle and the flat steel dipstick body. The plug-in fastener and the flat steel dipstick body are welded together. The oil-measuring reticulated steel strip is welded to the flat steel dipstick body, and the flat steel dipstick body is a double-screw spiral cross shape.

[0009] Furthermore, the plug-in fastening component includes a U-shaped steel plate welded to the flat steel ruler body. An insertion plate is welded inside the U-shaped steel plate. A number of protrusions are fixed on the inner wall of the U-shaped steel plate. The protrusions are integrally provided with the U-shaped steel plate. Arc-shaped convex points are provided at both ends of the U-shaped steel plate.

[0010] By adopting the above technical solution, the double-spiral flat steel ruler body can smoothly pass through the complex and multi-bent oil level gauge pipe, improving the oil extraction efficiency of the oil level gauge during insertion and extraction. At the same time, the flat steel ruler body cooperates with the ruler handle through the U-shaped steel plate, which is convenient for disassembly and easy for later maintenance.

[0011] Furthermore, a first sliding groove for the insertion plate to slide and plug is provided inside the ruler handle. Second sliding grooves are provided on both sides of the first sliding groove for the two sides of the U-shaped steel plate to plug in.

[0012] By adopting the above technical solution, through the cooperation of the first sliding groove and the insertion plate, and through the cooperation of the second sliding groove and the side of the U-shaped steel plate, the connection accuracy between the U-shaped steel plate and the ruler handle can be ensured.

[0013] Furthermore, a first groove that fits with the protrusion is provided on the groove wall on one side of the second sliding groove, and a second groove that fits with the arc-shaped convex point is provided on the groove wall on the other side of the second sliding groove.

[0014] By adopting the above technical solution, through the clamping cooperation of the first groove and the protrusion, and through the clamping cooperation of the second groove and the arc-shaped convex point, the connection stability between the U-shaped steel plate and the ruler handle can be improved.

[0015] Furthermore, the thickness of the protrusion is equal to the thickness of the U-shaped steel plate, and two protrusions are provided on each side of the U-shaped steel plate.

[0016] By adopting the above technical solution, the clamping cooperation stability between the first groove and the protrusion can be improved, and the clamping cooperation stability between the second groove and the arc-shaped convex point can also be improved.

[0017] Furthermore, a tip is provided on the ruler handle facing the flat steel ruler body, and convex lines are provided on the side of the tip close to the arc-shaped convex point.

[0018] By adopting the above technical solution, it can effectively prevent the overall oil level gauge from popping out and can also easily insert and extract the oil level gauge.

[0019] In summary, the beneficial technical effects of the present utility model are as follows:

[0020] 1. Adopting a double-spiral flat steel ruler body can smoothly pass through the complex and multi-bent oil level gauge pipe, improving the oil extraction efficiency of the oil level gauge during insertion and extraction;

[0021] 2. Adopting the first sliding groove and the second sliding groove, through the cooperation of the first sliding groove and the insertion plate, and through the cooperation of the second sliding groove and the side of the U-shaped steel plate, the connection accuracy between the U-shaped steel plate and the ruler handle can be ensured;

[0022] 3. The first groove and the second groove are adopted. By the snap fit of the first groove and the protrusion, and the snap fit of the second groove and the arc-shaped convex point, the connection stability between the U-shaped steel plate and the ruler handle can be improved.

[0023] 4. The settings of the tip and the convex stripes are adopted, which can effectively prevent the overall oil level gauge from popping out and can easily insert and pull out the oil level gauge. Description of the Drawings

[0029] The following further describes the present invention in detail with reference to the drawings.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-3 , the present invention provides a technical solution: an oil level gauge with a spiral structure, including a ruler handle 1, a flat steel ruler body 2 and a measuring oil mesh pattern steel strip 3 fixed to the flat steel ruler body 2. The ruler handle 1 and the flat steel ruler body 2 are connected by insertion. There is an insertion fastening part between the ruler handle 1 and the flat steel ruler body 2, and the insertion fastening part and the flat steel ruler body 2 are welded. The measuring oil mesh pattern steel strip 3 is welded and fixed to the flat steel ruler body 2, and the flat steel ruler body 2 is in a double-screw spiral cross shape.

[0032] Specifically, the flat steel ruler body 2 is made of two flat steels. Each flat steel is spiraled into a screw shape, and the two flat steels are spiraled and cross-welded with each other. After welding, it is welded to the oil measuring reticulated steel strip 3, and at the same time, a plug-in fastening part is welded at the other end.

[0033] Among them, the plug-in fastening part includes a U-shaped steel plate 4 welded on the flat steel ruler body 2. An insertion plate 5 is welded inside the U-shaped steel plate 4. A number of protrusions 6 are fixed on the inner wall of the U-shaped steel plate 4. The protrusions 6 are integrally provided with the U-shaped steel plate 4. Arc-shaped convex points 7 are provided at both ends of the U-shaped steel plate 4.

[0034] Specifically, the thickness of the protrusion 6 is equal to the thickness of the U-shaped steel plate 4, and two protrusions 6 are provided on each side of the U-shaped steel plate 4.

[0035] At the same time, a first sliding groove 8 for the insertion plate 5 to slide and plug is provided inside the ruler handle 1. Second sliding grooves 9 are provided on both sides of the first sliding groove 8 for the two sides of the U-shaped steel plate 4 to be inserted.

[0036] A first groove 10 that fits with the protrusion 6 is provided on the groove wall on one side of the second sliding groove 9, and a second groove 11 that fits with the arc-shaped convex point 7 is provided on the groove wall on the other side of the second sliding groove 9.

[0037] Among them, the U-shaped steel plate 4 is welded to the flat steel ruler body 2. When the U-shaped steel plate 4 is inserted, the insertion plate 5 slides into the first sliding groove 8. The two side edges of the U-shaped steel plate 4 slide into the second sliding groove 9. After the U-shaped steel plate 4 slides in, the protrusion 6 slides along the inside of the ruler handle 1 and automatically falls into the first groove 10 inside for clamping, and at the same time, the arc-shaped convex point 7 falls into the second groove 11 inside the ruler handle 1 for clamping.

[0038] Further, a tip 12 is provided on the ruler handle 1 facing the flat steel ruler body 2. A convex pattern 13 is provided on the side of the tip 12 close to the arc-shaped convex point 7. Further, after the ruler handle 1 is inserted into the equipment, it is inserted and docked through the tip 12. At the same time, the convex pattern 13 can be used to resist the insertion place to prevent the ruler handle 1 from popping out. At the same time, the setting of the convex pattern 13 can resist the arc-shaped convex point 7, further increasing the resistance stability with the flat steel ruler body 2.

[0039] The working principle of the present utility model: Based on the improvement of the flat steel of the existing oil dipstick, the steel strip of the existing oil dipstick flat steel is twisted into a spiral shape. At the same time, two flat steels are spiraled and cross-welded with each other. After welding, it is welded to the oil measuring reticulated steel strip 3, and at the same time, a U-shaped steel plate 4 is welded at the other end. The double-spiral shape can smoothly pass through the complex and multi-curved oil dipstick pipeline. At the same time, the connection between the ruler handle 1 and the U-shaped steel plate 4 adopts a sliding clamping connection. Therefore, the ruler handle 1 and the flat steel ruler body 2 can be easily disassembled for subsequent maintenance. At the same time, by using the tip 12 and the convex pattern 13 on the ruler handle 1, the whole oil dipstick can be effectively prevented from popping out, and the oil dipstick can be easily inserted and pulled out.
