Description

Technical Field

[0001] The utility model relates to the technical field of filter end covers, in particular to a filter. Background Art

[0002] The filter end cap is a component used to close one end of the filter, usually used for the air filter or oil filter of the automobile engine. It can help prevent dust and impurities from entering the filter and protect the engine or other equipment from damage.

[0003] In the existing technology, when the end cover is assembled with the filter, since the filter has a certain plasticity, multiple bolts are required to fix it during the assembly. During the fixing process, the bolts need to be fixed vertically, which will exert additional pressure on the filter and easily cause the filter to deform. After deformation occurs, if the filter is subjected to additional pressure during the process of fixing the end cover, it may cause the seal between the end cover and the filter housing to be loose, thereby affecting the filtering effect and performance of the filter.

Embodiment 1

[0023] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution: a filter, comprising: a filter body 11, a connecting ring 12 is arranged at the top of the filter body 11, a fixing plate 13 is arranged on one side of the connecting ring 12, a locking rod 14 is arranged inside the fixing plate 13, two clamping blocks 114 are arranged on the outside of the locking rod 14, two spring pieces 15 are arranged on the outside of the clamping blocks 114, a fixing plate 13 is arranged at one end of the spring piece 15, a fixing plate 112 is arranged on the top of the fixing plate 13, a top cover 115 is arranged on the outside of the fixing plate 112, limiting grooves 113 are equidistantly provided on the inner wall of the fixing plate 112, two limiting arms 111 are arranged on the inner surface of the limiting grooves 113, a spring piece 110 is arranged between the limiting arms 111, a pressure plate 18 is arranged at the bottom of the spring piece 110, and the pressure plate 18 Two triangular blocks 16 are provided at the bottom, the top of the filter body 11 is fixedly connected to the bottom of the connecting ring 12, the top of the connecting ring 12 is in contact with the bottom of the top cover 115, the inner wall of the top cover 115 is fixedly connected to the outer side of the second fixing plate 112, the inner surface of the limiting groove 113 opened in the second fixing plate 112 is clamped with one end of the limiting arm 111, one end of the limiting arm 111 is fixedly connected to one end of the second spring piece 110, the outer side of one end of the limiting arm 111 is slidably connected to the inner surface of the hollow plate 19, the top of the hollow plate 19 is fixedly connected to the top of the pressure plate 18, the bottom of the pressure plate 18 is fixedly connected to the triangular block 16, one side of the triangular block 16 is in contact with one side of the clamping block 114, one side of the clamping block 114 is in contact with the outer side of the locking rod 14, and one end of the locking rod 14 is fixedly connected to the inner wall of the fixing plate 13.

[0024] In this embodiment, when the staff operates, the top cover 115 is vertically aligned with the connecting ring 12 on the filter body 11, and the fixing plate 13 and the fixing plate 2 112 are aligned. Then, the hollow plate 19 is pressed to move downward in the fixing plate 13, and the pressure plate 18 and the hollow plate 19 are integrated, so they will naturally move downward, and the two triangular blocks 16 gradually approach the clamping block 114. The top of the clamping block 114 has a certain slope. When approaching, the two clamping blocks 114 will be affected by external forces, so that they move from different directions to the middle end of the fixing plate 13, and the middle end is designed with a locking rod 14. Therefore, when moving to a certain extent, the two clamping blocks 114 will fit together and wrap the locking rod 14.

When approaching, the two clamping blocks 114 are affected by external forces, so that they move from different directions to the middle end of the fixing plate 13. The middle end is designed with a locking rod 14. Therefore, when moved to a certain extent, the two clamping blocks 114 will fit together. , and wrap the locking rod 14. In this way, it is ensured that the top cover 115 and the connecting ring 12 on the filter body 11 can be firmly fixed together and are not easy to loosen or fall off. Secondly, when the pressure plate 18 moves downward, it will gradually approach the limiting groove 113. When it moves down to a certain extent, the spring sheet 110 is not affected by external forces and is released, pushing the limiting arm 111 into the limiting groove 113 and making it stuck at the end edge of the limiting groove 113. For this purpose, the movement of the triangular block 16 can be restricted and it will not move up and down at will;

[0029] By designing the spring sheet 15 on one side of the clamp block 114, when the clamp block 114 is not under pressure, the retractability of the spring sheet can be utilized to make the release of the restriction on the locking rod 14 automatic and without the need for additional operation. When the clamp block 114 is no longer under pressure, the spring sheet will automatically retract, thereby releasing the restriction on the locking rod 14 without the need for manual intervention.
