Manufacturing method of improved fuel filter

Technical realization elements:

3. The purpose of this utility model is to provide an improved fuel filter to solve the above-mentioned background art proposed existing improved fuel filter, the use of bolt connection to prevent the connection between the shell and the top cover, inconvenient The disassembly is inconvenient to replace the filter element, which leads to a problem that the practicability of the overall mechanism decreases.

4. In order to achieve the above purpose, the present utility model provides the following technical solutions: an improved fuel filter, comprising a shell, a top cover, a groove plate and a bottom shell, the top of the shell is attached to the top cover, and the top The outer wall of the cover is fixed with a groove plate, the outer walls of the two groove plates are in clearance fit with the inner groove of the housing, the bottom end of the housing is fixed with a bottom shell, and the outer wall of the housing is fixed with a connecting mechanism;

5. The connecting mechanism includes a swivel, a clamping plate, an arc block, a torsion spring and a connecting rod;

6. The outer walls of the two swivel seats are both fixedly connected to the housing, the interior of the swivel seat is movably connected with a clamping plate, one side of the clamping plate is processed with an arc block, and the other side of the clamping plate A torsion spring is attached to the torsion spring, and the internal clearance of the torsion spring is fitted with a connecting rod, and both the front and rear ends of the connecting rod are fixedly connected with the housing.

7. Preferably, the inside of the bottom shell is connected with a liquid outlet pipe, the top end of the liquid outlet pipe is connected with a mesh plate, and the top end of the mesh plate is attached with a filter element.

8. Preferably, a strengthening mechanism is installed at the top of the top cover;

9. The strengthening mechanism includes a connecting pipe, a protective shell, a pin and a nut;

10. The outer wall of the connecting pipe is fixedly connected to the top cover, the outer wall of the connecting pipe is attached to a protective shell, and the insides of the two protective shells are fitted with plug pins in a clearance fit, and the bottom ends of a plurality of the plug pins are all It is fixedly connected with the top cover, and the top end of the plug pin is screwed with a nut.

11. Preferably, the protective shell is symmetrically distributed with respect to the connecting pipe.

12. Preferably, a fixing mechanism is fixedly connected to the bottom end of the top cover;

13. The fixing mechanism includes a cylinder, an ejector rod, a pressure plate, a top plate and a spring;

14. The top ends of the two cylinders are fixed to the top cover, the inner gap of the cylinder is fitted with a top rod, the bottom end of the top rod is fixedly connected with a pressure plate, and the lower surface of the pressure plate is connected to the filter element The top of the ejector rod is fixedly connected to the top plate, the outer wall of the top plate is in clearance fit with the inner clearance of the cylinder, and the inner clearance of the cylinder is matched with a spring.

The ends are attached to the cylinder and the top plate respectively.

15. Preferably, the ejector rod and the pressure plate are arranged perpendicularly.

16. Compared with the prior art, the beneficial effect of the present utility model: Compared with the traditional technology, the improved fuel filter has the following advantages:

17. Through the coordinated use of swivel, chuck, arc block, torsion spring and connecting rod, the chuck is rotated on the outer wall of the swivel, the chuck compresses the torsion spring on the outer wall of the connecting rod, and the chuck drives the arc block Separate from the groove plate, and then move the top cover up at the top of the housing, and the top cover drives the groove plate to separate from the housing, and then replaces the filter element in the housing. The traditional bolt connection method is changed to facilitate the replacement of the filter element and improve the overall mechanism. Practicality

18. Through the use of connecting pipes, protective shells, pins and nuts, etc., a protective shell is set on the outer wall of the connecting pipe. The two protective shells increase the tightness of the connection between the connecting pipe and the top cover, and at the same time increase the strength of the outer wall of the connecting pipe , To prevent the connecting pipe from bending and breaking, extend the service life of the whole mechanism, and greatly meet the needs of the filter in the automotive industry.
