Technical Field

[0001] The utility model relates to the technical field of injection molding assemblies of fuel filters, in particular to a threaded connection sleeve structure used for fuel filters. Background Art

[0002] The fuel filter is an important part of the fuel system, used to filter impurities in the fuel and keep the fuel system clean. During the installation and removal of the fuel filter, a reliable connection structure is required to ensure the tightness and stability of the connection. The traditional connection method usually adopts bolt connection or direct welding, which has some shortcomings. For example, bolt connection requires additional fasteners, which increases the complexity and cost of installation; while welding may cause thermal damage to the filter, affecting its performance and service life. Therefore, it is necessary to develop a new type of connection sleeve structure to simplify the installation process and improve the stability and reliability of the connection.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] Example 1

[0016] like Figure 1 , Figure 2 As shown, a specific embodiment of a threaded connection sleeve structure for a fuel filter described in the utility model comprises a cylindrical connection sleeve 1, one end of which is internally provided with a thread 2 for connecting with other components, the diameter of the thread 2 is 80.0, and the pitch of the thread 2 is 3.0, which ensures the tightness and stability of the connection.

[0017] In addition, twelve reinforcing ribs 3 are equidistantly arranged on the periphery of the connecting sleeve 1, and a circle of reinforcing rings 4 are provided. The arrangement of these reinforcing ribs 3 and reinforcing rings 4 enhances the structural strength and stability of the connecting sleeve 1, enabling it to withstand greater external forces. The width of the lower half of the reinforcing ribs 3 is greater than that of the upper half. Since the lower half of the connecting sleeve 1 is provided with a snap hole 5 and the structural strength is insufficient, a larger width is adopted in the lower half to improve the structural strength, while a smaller width in the upper half can reduce weight and save materials. This design can optimize the overall structure.

[0018] In order to facilitate the installation and docking, buckle holes 5 are equidistantly provided on the side wall of the connecting sleeve 1 , and the connecting sleeve 1 and the filter can be quickly and accurately docked and installed through the buckle holes 5 .

[0019] A seal is provided between the fuel filter and the threaded connection sleeve structure to ensure the sealing of the connection. The connection sleeve 1 structure of the utility model is manufactured by injection molding process, and has the advantages of simple structure, practicality, high cost-effectiveness, etc.

[0020] Working principle of the utility model: When the utility model is used, a buckle is used to match and connect with the filter, and the connecting sleeve 1 is tightly connected with the fuel filter by tightening with a locking ring and a locking rod, and then the connecting sleeve 1 is assembled and connected with other parts through the thread 2 in the connecting sleeve 1 to achieve a tight and stable connection effect.

[0021] The components in this article are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0022] Although the specific embodiments of the present invention are described in detail above, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the present invention, and modifications or deformations without creative labor are still within the scope of protection of the present invention.
