Abstract
The invention discloses a filtering core tube body locking method, which is characterized by comprising the following steps that a, firstly, an upper cover is fixed, and in addition, the upper cover and a filter core tube body are primarily connected through screw threads; b, a locking element is elected, the center of the top surface of a body of the locking element is provided with a round groove, a position limiting concave pit is formed in the groove wall of the round groove, and an orthohexagonal hole is formed in the center of the bottom surface of the body; c, the round groove of the body is arranged on the bottom of the filter core tube body in a sleeving way, the position limiting concave pit formed in the groove wall of the round groove is tightly combined with a reinforcing rib arranged on the outer wall of the filter core tube body, then, a socket head wrench extends into the orthohexagonal hole, and the locking element is driven to rotate through rotating the socket head wrench, so that the filter core tube body is tightly locked. The socket head wrench matched with the orthohexagonal hole is positioned under the filter core tube body, so that the socket head wrench can be easily rotated for locking the filter core tube body, and the defect that the filter core tube body cannot be tightly locked due to the space limitation in the traditional mode can be effectively overcome.
Description
Technical field
The invention belongs to filter core cylindrical shell installing area, specifically, particularly relate to a kind of filter core cylindrical shell locking method.
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.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of easy to operate, labour-saving filter core cylindrical shell locking method.
Technical scheme of the present invention is as follows: a kind of filter core cylindrical shell locking method, is characterized in that comprising the steps:
Step a: first fix upper cover (S), and upper cover (S) and filter core cylindrical shell (T) are tentatively threaded togather;
Step b: the locking member selecting a corresponding size specification, 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;
Step c: the bottom circular groove (1a) of body (1) being sleeved on filter core cylindrical shell (T), and spacing pit on circular groove (1a) cell wall (1a ') combine closely with the reinforcement on filter core cylindrical shell (T) outer wall, again inner hexagon spanner (L) is stretched in regular hexagon hole (1b), and drive locking member to rotate by rotating inner hexagon spanner (L), thus filter core cylindrical shell and upper cover (S) are locked together;
Steps d: after locking, takes off locking member and inner hexagon spanner (L).
Adopt above-mentioned locking method, because body (1) is sleeved on the bottom of filter core cylindrical shell, and inner hexagon spanner (L) 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 invention, 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: the circular groove implementing locking member during this locking method 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 structure of the present invention is simple, locking is convenient, laborsaving.
Accompanying drawing explanation
Structural representation when Fig. 1 is the enforcement of this locking method;
Fig. 2 is the schematic diagram of locking member in Fig. 1;
Fig. 3 is that the A-A of Fig. 2 is to sectional view.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Fig. 1,2 and 3, a kind of filter core cylindrical shell locking method, is characterized in that comprising the steps:
Step a: first fix upper cover S, and upper cover S and filter core cylindrical shell T is tentatively threaded togather.
Step b: the locking member selecting a corresponding size specification, 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 pit 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.
In addition, the number of described spacing pit 1a ' is 4, and the degree of depth of spacing pit 1a ' is 0.5-1.5mm.Further, described spacing pit 1a ' is identical with the outline of the profile that circular groove 1a is formed and a gear.
Step c: the bottom circular groove 1a of body 1 being sleeved on filter core cylindrical shell T, and the spacing pit 1a ' on circular groove 1a cell wall combines closely with the reinforcement on filter core cylindrical shell T outer wall, again inner hexagon spanner L is stretched in the 1b of regular hexagon hole, and drive locking member to rotate by rotating inner hexagon spanner L, thus filter core cylindrical shell and upper cover S are locked together;
Steps d: after locking, takes off locking member and inner hexagon spanner L.
The foregoing is only preferred embodiment of the present invention, is not restriction with the present invention, and all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
