Description

Rotatable connecting device of machine oil gun

Technical Field

The utility model relates to an engine manufacturing technical field specifically is an oil gun rotatable connecting device.

Background

When the engine is used for manufacturing site engine oil adding, the engine oil adding gun is rotated and moved due to frequent stress, the currently used engine oil adding measuring gun cannot rotate, the engine oil adding gun is abraded when the engine oil is stressed and needs to rotate to other positions, even fine metal powder pollution can be generated, and the cleanliness of the engine oil is easily influenced in the using process for a long time.

SUMMERY OF THE UTILITY MODEL

To the current defect of the aforesaid, the utility model aims to provide an oil gun rotatable connection device makes the oil gun rotate in a flexible way through the cooperation, and it is convenient to use, avoids the wearing and tearing of oil gun.

The technical scheme of the utility model as follows:

the utility model provides a rotatable connecting device of machine oil gun, includes the reducing joint, and the both ends of reducing joint are big footpath pipe and path pipe respectively, and the intraductal coaxial antifriction bearing that is provided with in big footpath pipe, the antifriction bearing outer lane is connected with big footpath pipe inner circle interference fit, and the antifriction bearing inner circle is used for being connected with the play oil pipe cooperation of machine oil gun, the path pipe is used for being connected with the entry cooperation in engine oil storehouse.

Preferably, the inner diameter of the rolling bearing is equal to the inner diameter of the small-diameter round tube. The oil outlet pipe of the engine oil gun is ensured to pass through by adopting the inner diameter of the better small-diameter round pipe, and the wall thickness of the small-diameter round pipe is also ensured.

Preferably, the top surface of the large-diameter circular tube is flush with the top surface of the rolling bearing. The height of the large-diameter circular pipe is limited, so that the rotatable connecting device is compact as a whole, and space and cost are saved.

The utility model has the advantages that:

the utility model discloses the device is convenient succinct, easy preparation, the suitability is strong, do not need too many cooperation required precision, guarantee the bearing, the reducing joint, add the machine oil rifle three interconnect can, the junction can use the glue fastening, pull down when needing the renewal part can, do not need whole device whole change, also can pull down old device when adding the machine oil rifle and change and use on new machine oil rifle that adds, therefore, the clothes hanger is strong in practicability, also avoided simultaneously because the inhomogeneous machine oil rifle that leads to of atress with there being wearing and tearing between the machine oil mouth, lead to the metal dust, pollute the risk of machine oil.

Fig. 3 is the utility model discloses a but machine oil gun swivelling joint device and machine oil gun connected's schematic diagram.

In the figure, 1 is a reducing joint, 101 is a large-diameter circular tube, 102 is a small-diameter circular tube, and 2 is a rolling bearing.

Detailed Description

In order to explain the technical content, the achieved objects and the effects of the present invention in detail, the following description is made in conjunction with the embodiments and the accompanying drawings. In the description of the embodiments, it is to be understood that the terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for convenience of describing the embodiments and simplifying the description, but do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed and operated in a specific orientation and thus should not be construed as limiting the present invention.

As shown in fig. 1, the rotatable connecting device of an oil gun according to the embodiment of the present disclosure includes a reducer union 1, and referring to fig. 2, two ends of the reducer union 1 are respectively a large diameter circular tube 101 and a small diameter circular tube 102, a rolling bearing 2 is coaxially disposed in the large diameter circular tube 101, an outer ring of the rolling bearing 2 is connected with an inner ring of the large diameter circular tube 101 in an interference fit manner, an inner ring of the rolling bearing 2 is used for being connected with an oil outlet pipe of the oil gun in a fit manner, and the small diameter circular tube 102 is used for being connected with an inlet of an engine oil bin in.

As shown in fig. 3, the reducer union 1 and the rolling bearing 2 are installed in an interference fit manner, and in addition, the reducer union and the rolling bearing can be fastened by tightening glue, 262 glue can be used, or the reducer union and the rolling bearing can be connected in an interference fit manner, so that the reducer union and the rolling bearing are integrated; the rolling bearing 2 can use the existing product, and is selected according to the external diameter of the oil outlet pipe of the oil gun used on site, so that the device is convenient and simple, is easy to manufacture, has strong applicability, and does not need too many matching precision requirements. In-process at the engine with machine oil, insert antifriction bearing 2 inner circles with the play oil pipe of machine oil rifle in, through gluing the fastening, the entry that inserts engine machine oil storehouse with path pipe 102 can carry out the work that adds machine oil, and it can the rotary transposition to add the machine oil rifle during, can adapt to the change that the scene adds the machine oil position, and the practicality is strong, has also avoided simultaneously because the inhomogeneous machine oil rifle that leads to of atress adds with and has wearing and tearing between the machine oil mouth, leads to the metal dust, pollutes the risk of machine oil, reaches the utility model discloses a purpose.

In a preferred embodiment of the present embodiment, the inner diameter of the rolling bearing 2 is equal to the inner diameter of the small-diameter round tube 102. The inner diameter of the small-diameter round tube 102 is better, so that the oil outlet pipe of the engine oil gun can pass through, and the wall thickness of the small-diameter round tube 102 is guaranteed.

Preferably, the top surface of the large-diameter circular tube 101 is flush with the top surface of the rolling bearing 2. The height of the large-diameter circular tube 101 is limited, so that the rotatable connecting device is compact as a whole, and space and cost are saved.

Although the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that modifications and improvements can be made thereto. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
