Abstract
The utility model discloses a kind of filter core cylindrical shell locking member, it is characterized in that: the body of this locking member is cylindrical structure, a circular groove is provided with at the end face center of body, the cell wall of this circular groove is circumferentially evenly equipped with 2-5 spacing pit, the degree of depth of these spacing pits and the deep equality of circular groove; The center of described body bottom surface is provided with a regular hexagon hole, and the degree of depth in this regular hexagon hole is 3-5mm.When the utility model uses, the circular groove of body is sleeved on the bottom of filter core cylindrical shell, and the spacing pit on circular groove cell wall and the reinforcement on filter core cylinder body outer wall are combined closely, because the inner hexagon spanner coordinated with regular hexagon hole is positioned at below filter core cylindrical shell, so just energy ease rotation inner hexagon spanner, thus locking filter core cylindrical shell, thus effectively overcome traditional approach can not lock filter core cylindrical shell defect because of limited space, and the utility model structure is simple, locking is convenient, laborsaving.
Description
Technical field
The utility model belongs to filter core cylindrical shell installing area, specifically, particularly relates to a kind of filter core cylindrical shell locking member.
Background technology
Filter core after loading filter core cylindrical shell needs filter core cylindrical shell and upper cover to be locked together.At present, generally be set with a belt or a plastic spanner at the middle part of filter core cylindrical shell, the reinforcement close contact of belt or plastic spanner and external of filter core cylinder, then rotate filter core cylindrical shell by rotating belt or plastic spanner, thus make filter core cylindrical shell and upper cover locking.
The maximum defect of above-mentioned locking mode is: if the close together of multiple filter core cylindrical shell, so space is just more limited, in this case adopt above-mentioned locking mode to lock the just bad enforcement of filter core cylindrical shell, even if can barely lock, also there is the defect of inconvenient operation, effort, be badly in need of solving above-mentioned technical barrier for this reason.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of filter core cylindrical shell locking member, for conveniently, effortlessly locking filter core cylindrical shell by this locking member.
The technical solution of the utility model is as follows: a kind of filter core cylindrical shell locking member, it is characterized in that: the body (1) of this locking member is cylindrical structure, a circular groove (1a) is provided with at the end face center of body (1), the cell wall of this circular groove is circumferentially evenly equipped with 2-5 spacing pit (1a '), the degree of depth of these spacing pits (1a ') and the deep equality of circular groove (1a); The center of described body (1) bottom surface is provided with a regular hexagon hole (1b), and the degree of depth in this regular hexagon hole is 3-5mm.
During locking, first fixed cover (S), again the circular groove (1a) of body (1) is sleeved on the bottom of filter core cylindrical shell (T), and spacing pit on circular groove (1a) cell wall (1a ') fit tightly with the reinforcement on filter core cylinder body outer wall, again inner hexagon spanner is stretched in regular hexagon hole (1b), and drive the utility model to rotate by rotating inner hexagon spanner, thus locking filter core cylindrical shell.Because body (1) is sleeved on the bottom of filter core cylindrical shell, and inner hexagon spanner is positioned at below filter core cylindrical shell, so just conveniently, effortlessly can lock filter core cylindrical shell, even if limited space also can easily complete, thus overcome traditional locking mode well because the defect of limited space and performance difficulty.
As prioritization scheme, the number of described spacing pit (1a ') is 4, and the degree of depth of spacing pit (1a ') is 0.5-1.5mm.In said structure, the number of described spacing pit (1a ') is moderate, can ensure structural strength of the present utility model, can ensure again successfully to rotate filter core cylindrical shell, thus by filter core cylindrical shell and upper cover locking.In addition, the degree of depth of spacing pit (1a ') is that 0.5-1.5mm is moderate, is also reliably lock filter core cylindrical shell to ensure.
As preferably, and described spacing pit (1a ') identical with the outline of the profile that circular groove (1a) is formed and a gear.
Beneficial effect: when the utility model uses, the circular groove of body is sleeved on the bottom of filter core cylindrical shell, and the spacing pit on circular groove cell wall and the reinforcement on filter core cylinder body outer wall are combined closely, because the inner hexagon spanner coordinated with regular hexagon hole is positioned at below filter core cylindrical shell, so just energy ease rotation inner hexagon spanner, thus locking filter core cylindrical shell, thus effectively overcome traditional approach can not lock filter core cylindrical shell defect because of limited space, and the utility model structure is simple, locking is convenient, laborsaving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is using state figure of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Fig. 1,2 and 3, a kind of filter core cylindrical shell locking member, the body 1 of this locking member is cylindrical structure, a circular groove 1a is provided with at the end face center of body 1, the cell wall of this circular groove 1a is circumferentially evenly equipped with 2-5 spacing pit 1a ', in the present case, the number of spacing pit 1a ' is preferably 4.The degree of depth of these spacing pit 1a ' and the deep equality of circular groove 1a, and the degree of depth of spacing pit 1a ' is 0.5-1.5mm, and can more preferably 0.7,1,1.2 and 1.4mm.Further, described spacing pit 1a ' is identical with the outline of the profile that circular groove 1a is formed and a gear.
In addition, the center of described body 1 bottom surface is provided with a regular hexagon hole 1b, and the degree of depth of this regular hexagon hole 1b is 3-5mm, and can more preferably 3.5,4 and 4.5mm.
The foregoing is only preferred embodiment of the present utility model; it is not restriction with the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
