Description

Technical Field

[0001] The utility model relates to the field of automobile devices, in particular to an assembled oil nozzle edge-wrapped rubber core. Background Art

[0002] The oiling process for products such as plastics, hardware, and handbags is mainly done manually. Oil is applied directly to the corresponding parts of the workpiece using a needle according to product requirements, and the quality is determined based on intuition and experience. This traditional operation is simple, inefficient, and of poor quality, and cannot meet workload requirements. Furthermore, the dispensing of glue cannot be uniform. The use of an oiling machine can improve the efficiency of dispensing and greatly improve the uniformity of dispensing.

[0003] Although the prior art improves the overall usability of the device by providing a rubber core on the side wall of the fuel nozzle, when the vehicle is subjected to forces in different directions such as the front, rear, left, and right during driving, the inner and outer steel sleeves will open and close, causing repeated and strong tearing effects on the polyurethane, thereby shortening the product life. Therefore, those skilled in the art have provided an assembled fuel nozzle edge-wrapped rubber core to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an assembled oil nozzle edge-wrapped rubber core, which provides an assembled oil nozzle edge-wrapped rubber core with enhanced tear resistance and pressure bearing capacity by changing the second steel sleeve and the third steel sleeve into two horizontal half steel sleeves with threads.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an assembled oil nozzle edge-wrapped rubber core, comprising a steel shaft, with mounting holes respectively opened at both ends of the steel shaft, a second steel sleeve provided on one side of the middle of the steel shaft, a third steel sleeve provided on the other side of the middle of the steel shaft, and a first steel sleeve provided on the side wall of the second steel sleeve;

[0006] Through the above technical solution, the second steel sleeve and the third steel sleeve are changed into two horizontal half steel sleeves with threads, thereby enhancing the tear resistance and pressure bearing capacity. At the same time, polyurethane is glued to the outside of the second steel sleeve and the third steel sleeve during processing to form a whole. The first steel sleeve outside the polyurethane is also a whole. This structure enhances the tear resistance and pressure bearing capacity when subjected to stress during driving of the car.

[0007] Furthermore, the bottom end of the second steel sleeve and the top end of the third steel sleeve are adapted to each other;

[0008] The above technical solution improves the stability of installation.

[0009] Furthermore, the diameter of the side wall of the second steel sleeve is equal to the diameter of the inner side wall of the first steel sleeve;

[0010] Through the above technical solution, the first steel sleeve is effectively installed.

[0011] Furthermore, the inner side wall and the side wall of the second steel sleeve are respectively provided with lubricating oil;

[0012] Through the above technical solution, friction is effectively reduced and service life is increased.

[0013] Furthermore, polyurethane is provided at the connection between the second steel sleeve and the third steel sleeve;

[0014] Through the above technical solution, the two steel sleeves are effectively fixed and bonded.

[0015] Furthermore, threads are provided on the lower portion of the inner side wall of the second steel sleeve and the side wall of the third steel sleeve;

[0016] Through the above technical solution, the second steel sleeve and the third steel sleeve are effectively installed.

[0017] Furthermore, the inner side walls of the second and third steel sleeves are equal in diameter to the middle of the steel shaft;

[0018] Through the above technical solution, the second steel sleeve and the third steel sleeve are effectively installed.

[0019] The utility model has the following beneficial effects:

[0020] 1. In the present invention, the second and third steel sleeves are converted into two transverse half-steel sleeves with threads, thereby enhancing the tear resistance and pressure bearing capacity. At the same time, polyurethane is adhered to the outside of the second and third steel sleeves during processing to form a whole. The first steel sleeve outside the polyurethane is also a whole. This structure enhances the tear resistance and pressure bearing capacity when subjected to force during the driving process of the car.

[0021] 2. In the present invention, lubricating oil is applied between the parts, thereby reducing internal friction and extending the service life of the product. BRIEF DESCRIPTION OF THE DRAWINGS
