Description

Technical Field

[0001] This utility model relates to the technical field of oil dipsticks, specifically a detachable spiral oil dipstick. Background Technology

[0002] With the rapid pace of vehicle model updates and the increasing variety of engine types, the types of oil dipsticks are also increasing. How to reduce the variety of oil dipstick handles and ensure the reliability of the oil dipstick has become a concern for designers.

[0003] Currently, the oil dipstick handle and the oil dipstick plate are an integral, non-separable unit. Since the oil dipstick plates of various machines are different, the design of the oil dipstick requires repeated three-dimensional design, calculation of sealing performance, mold making, production, and experimental verification of the oil dipstick handle. Moreover, due to the differences in the process level of various manufacturers, problems such as poor sealing at the sealing point of the oil dipstick handle sometimes occur during the testing of new oil dipsticks. Utility Model Content

[0004] The purpose of this invention is to provide a detachable spiral oil dipstick that has high disassembly and installation efficiency, strong installation stability, and good sealing performance.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The device includes a ruler handle and a ruler rod detachably connected to the ruler handle. A connecting plate is fixed to the end of the ruler rod near the ruler handle, and a measuring plate is fixed to the end of the ruler rod away from the ruler handle. A fixing member is fixed to the end of the ruler handle near the ruler rod. A pull rod is fixed to the end of the ruler handle away from the ruler rod, and a pull ring is fixed to the end of the pull rod. A sealing ring is embedded in the end of the ruler handle near the fixing member.

[0007] Furthermore, the fixing member includes a clamp plate fixed to the handle, and two clamp plates are symmetrically arranged, with the two clamps being biased towards the middle of the handle away from the end of the handle.

[0008] The above technical solution uses a folded clamping plate, which allows for adjustable spacing between the clamping plates and is also suitable for connecting plates of different sizes.

[0009] Furthermore, the side of the clamping plate is provided with through holes, and a plurality of through holes are provided at equal intervals along the length of the clamping plate. The side of the connecting plate is provided with through holes, the diameter of which is greater than or equal to the diameter of the through holes.

[0010] The above technical solution facilitates quick connection and installation of the clamping plate and the connecting plate.

[0011] Furthermore, the ruler handle is fixed with a concave hole facing the end of the ruler rod, and a polyurethane nest is embedded inside the concave hole. The polyurethane nest has an insertion hole inside, the size of which is smaller than the size of the connecting plate. The polyurethane nest has an inwardly inclined surface facing the end of the connecting plate.

[0012] Using the above technical solution, because the polyurethane nesting has good elasticity and the size of the insertion hole is smaller than the size of the connecting plate (including length and width parameters), after the connecting plate is inserted into the insertion hole, the insertion hole wraps around the outside of the connecting plate, thus further fixing the connecting plate and limiting its position. Combined with the aforementioned clamping plate, the connecting plate can be completely fixed. Furthermore, the side of the ruler handle is provided with a groove, the sealing ring is fixed inside the groove, and the outer side of the sealing ring is convex.

[0013] By adopting the above technical solution, after insertion, the sealing ring on its side abuts against the object, and the outer side of the sealing ring is convex, which further increases the friction of the contact and thus further improves the sealing performance.

[0014] Furthermore, the handle of the ruler has a chamfer facing the end of the ruler rod.

[0015] By adopting the above technical solution, the chamfer on the ruler handle can better fit the insertion point when the ruler handle is placed at the top of the engine oil chamber, thereby improving the sealing performance.

[0016] In summary, the beneficial technical effects of this utility model are as follows:

[0017] 1. It adopts clamps with an offset design, which allows for adjustable clamp spacing and is also suitable for connecting plates of different sizes.

[0018] 2. Polyurethane nesting is adopted. Due to the good elasticity of polyurethane nesting and the fact that the size of the socket is smaller than that of the connecting plate (including length and width parameters), after the connecting plate is inserted into the socket, the socket is wrapped around the outside of the connecting plate, which further fixes the connecting plate and limits the position of the connecting plate. Combined with the fixation of the clamp mentioned above, the connecting plate can be completely fixed.

[0019] 3. A sealing ring is used. After the ruler handle is inserted, the sealing ring on its side abuts against it. At the same time, the outer side of the sealing ring is convex, which further increases the friction of the contact and thus further improves the sealing performance. The chamfer on the ruler handle can better fit the insertion point when the ruler handle is placed on the top of the engine oil chamber, thus improving the sealing performance.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] 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.

[0026] Please see Figure 1-2 The present invention provides a technical solution comprising: a ruler handle 1 and a ruler rod 2 detachably connected to the ruler handle 1; a connecting plate 4 is fixed to the end of the ruler rod 2 near the ruler handle 1; a measuring plate 5 is fixed to the end of the ruler rod 2 away from the ruler handle 1; a fixing member is fixed to the end of the ruler handle 1 near the ruler rod 2; a pull rod 6 is fixed to the end of the ruler handle 1 away from the ruler rod 2; a pull ring 7 is fixed to the end of the pull rod 6; and a sealing ring 8 is embedded in the end of the ruler handle 1 near the fixing member.

[0027] The fastener includes a clamping plate 9 fixed to the handle 1. Two clamping plates 9 are symmetrically arranged, with the two clamping ends away from the handle 1 being bent toward the middle of the handle 1.

[0028] The clamping plate 9 has through holes 10 on its side, and several through holes 10 are provided at equal intervals along the length of the clamping plate 9. The connecting plate 4 has through holes 11 on its side, and the diameter of the through holes 11 is greater than or equal to the diameter of the through holes 10.

[0029] The clamping plate 9 and the connecting plate 4 are fixed with screws and nuts. During installation, the connecting plate 4 is slid in between the two clamping plates 9, the through hole 11 on the connecting plate 4 is aligned with the through hole 10, the screws are inserted into the through hole 10 and the through hole 11, and the clamping plate 9 and the connecting plate 4 are fixed by tightening with nuts.

[0030] A recessed hole 12 is further fixed at the end of the ruler handle 1 facing the ruler rod 2. A polyurethane nest 13 is embedded inside the recessed hole 12. The polyurethane nest 13 has an insertion hole 14 inside, the size of which is smaller than that of the connecting plate 4. The end of the polyurethane nest 13 facing the connecting plate 4 has an inwardly inclined surface 15. Then, while the connecting plate 4 is fixed to the clamping plate 9 with screws, the front end of the connecting plate 4 is inserted into the insertion hole 14. Since the polyurethane nest 13 has good elasticity and the size of the insertion hole 14 is smaller than that of the connecting plate 4 (including length and width parameters), after the connecting plate 4 is inserted into the insertion hole 14, the insertion hole 14 wraps around the outside of the connecting plate 4, thus further fixing the connecting plate 4 and limiting the position of the connecting plate 4. Combined with the fixing of the clamping plate 9, the connecting plate 4 can be completely fixed. At the same time, the clamping plate 9 is set to bend, so the spacing of the clamping plate 9 can be adjusted, and it is also suitable for connecting connecting plates 4 of different sizes.

[0031] A groove 16 is provided on the side of the ruler handle 1, and the sealing ring 8 is fixed inside the groove 16. The outer side of the sealing ring 8 is convex.

[0032] The end of the ruler handle 1 facing the ruler rod 2 has a chamfer 3.

[0033] The chamfer 3 on the handle 1 can better fit the insertion point when the handle 1 is placed on top of the engine oil chamber, thereby improving the sealing performance. At the same time, after insertion, the sealing ring 8 on its side abuts, and the outer side of the sealing ring 8 is convex, which further increases the friction of the abutment, thereby further improving the sealing performance.

[0034] The working principle of this utility model is as follows: the ruler handle 1 and the ruler rod 2 can be disassembled and fixed by screws on the clamping plate 9 and the connecting plate 4. At the same time, the connecting plate 4 is inserted into the inside of the ruler handle 1, which can quickly complete the installation and disassembly of the ruler rod 2. It is convenient for the ruler handle 1 to connect with ruler rods 2 of different specifications and structures. On the basis of the disassembly performance, the ruler handle 1 with chamfer 3 and the sealing ring 8 installed on the side of the ruler handle 1 improve the sealing performance of the ruler handle 1 after placement.
