In the prior art, because the structural arrangement needs, the dipstick guide pipe itself generally has a natural bend, as shown in fig. 1 to 2, a first natural bend 101 and a second natural bend 102 are arranged on the dipstick guide pipe joint 10 in the prior art, because the first natural bend 101 and the second natural bend 102 meet the requirement of spatial structural arrangement, the structural characteristic of spatial bend exists, because the dipstick generally adopts a slender steel sheet structure, when the dipstick 20 is inserted, the dipstick not only has a bending condition in the dipstick guide pipe, but also can generate a spiral deformation condition along the longitudinal axis direction of the dipstick 20, because the first natural bend 101 and the second natural bend 102 are far away from the insertion opening of the dipstick guide pipe, the position of the dipstick in the handle 201 direction is inaccurate.

The prior art has the following defects: the oil rule guide pipe using the cold-drawing pipe material and the oil rule combination of the steel sheet structure lead to the condition that the handle direction of the oil rule is not unique after assembly and the appearance difference is large due to different angles of installing the oil rule by different operators and users. The machine oil level difference of different handle angular surveying is great, leads to the machine oil level survey inaccurate, and the product uniformity is poor, and the dipstick handle interferes with parts on every side easily, and required design space is big.

The information disclosed in this background section is only for enhancement of understanding of the general background of the utility model and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

SUMMERY OF THE UTILITY MODEL

In order to achieve the purpose, the utility model provides a guide pipe structure of an oil level gauge, which comprises a body, wherein the body comprises a positioning bend, the positioning bend is arranged at one end close to an insertion opening of the body, and the distance between the positioning bend and the insertion opening is not enough to enable the oil level gauge to generate spiral deformation along the longitudinal axis of the oil level gauge in the body, so that a handle of the oil level gauge can be ensured to be positioned at two positions of a forward direction or a reverse direction.

In a preferred embodiment, the body further comprises a first natural bend and a second natural bend; the first natural bend is arranged in the middle of the body; the second natural bend is arranged at one end close to the body and far away from the insertion opening; wherein the central axis of the body at the first natural bend is not coplanar with the central axis of the body at the second natural bend.

In a preferred embodiment, the body further comprises a fixing portion disposed between the positioning bend and the insertion opening, and the fixing portion is provided with a mounting hole for fixing the body by a bolt.

Compared with the prior art, the oil rule guide pipe structure has the following beneficial effects: this scheme is being close to and is inserting the mouth department and having set up a location curved, and the distance between the location is curved and the inserted hole is not enough to make the oil rule take place to follow the helical deformation of the longitudinal axis of oil rule at this internal, and then can guarantee that the oil rule inserts after, the handle of oil rule is in two positions of forward or reverse to when guaranteeing different operators to operate, the rate of accuracy of measured oil liquid level.

Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.

As shown in fig. 5 to 6, according to the oil level gauge guiding structure of the preferred embodiment of the present invention, the oil level gauge guiding structure includes a body 30, the body 30 of this embodiment is generally made of a cold drawn pipe material, and the oil level gauge 20 is generally made of an elongated steel sheet structure. The body 30 includes the curved 303 of location, and the curved 303 setting of location is in the inserted hole one end that is close to the body 30, and the curved 303 of location is not enough to make the dipstick 20 take place the spiral deformation along the longitudinal axis of dipstick 20 in the body 30 apart from the distance of inserted hole, and then can guarantee that the handle 201 of dipstick 20 is in two positions in forward or reverse direction. As shown in fig. 3 and 4, since the measuring portion 203 and the middle portion 202 of the oil level gauge 20 are perpendicular to each other, when the oil level gauge 20 is pulled out, when the measuring portion 203 passes through the positioning bend 303, the measuring portion 203 does not scratch the inner wall of the body 30 due to the oil level measuring mark being affected by the oil level gauge 20 being bent at the positioning bend 303, so that the measuring accuracy is affected.

In some embodiments, the body 30 further includes a first natural bend 301 and a second natural bend 302. The first natural bend 301 is disposed at the middle of the body 30. A second natural bend 302 is provided near an end of the body 30 remote from the insertion opening. Wherein the central axis of the body 30 at the first natural bend 301 is not coplanar with the central axis of the body 30 at the second natural bend 302. That is, the first natural bend 301 and the second natural bend 302 are in a state of spatial bending, which is likely to cause the oil dipstick 20 to generate a spiral deformation along the longitudinal central axis of the oil dipstick 20 inside the conduit of the oil dipstick 20 after the oil dipstick 20 is inserted.

In some embodiments, the body 30 further includes a fixing portion 304 disposed between the positioning bend 303 and the insertion opening, and the fixing portion 304 is provided with a mounting hole for fixing the body 30 by a bolt.
