Description

A kind of filter screws handle

Technical field

Handle is screwed the utility model relates to a kind of filter.

Background technique

In the assembling process of chemical solution filter machine, often uses and screw handle and the cooperation of upper beam ring to the upper cover of filtering It is fixed, but the existing handle that screws is not big enough in the presence of transmitting torque, the unstable problem of structure leads to the upper cover of filter It is not firm to lock；It also screws handle and is substantially integral structure, in later period maintenance and assembling, often have medical fluid contamination To screwing on handle, corrosion screws handle, causes to replace and entirely screws handle, and maintenance cost is high.

Summary of the invention

The purpose of the utility model is to overcome disadvantages described above, provide a kind of structure is stronger, transmitting more energetically Square screws handle.

To achieve the above object, the concrete scheme of the utility model is as follows:

A kind of filter screws handle, including circular hand-held part and for screwing portion, institute with what the external world was connect State that the portion of screwing is cylindrical, the hand-held part is connect by the stiffening plate of three triangles with the portion of screwing, described in three Stiffening plate is arranged at equal intervals, and the outer wall of the hand-held part is equipped with arc-shaped groove at equal intervals, and the portion that screws leads to equipped with center Hole and metal nuts are nested with, the axis of the metal nuts is overlapped setting, and the metal with the axis of the central through hole The internal diameter of nut is less than or equal to the internal diameter of central through hole, and arc-shaped through-hole is provided between the adjacent groove, and the arc is logical Hole is for wearing adhesive tape.

The utility model, further, the metal nuts bottom end are in different planes from the bottom end in the portion of screwing.

The utility model further includes further three arc panels, and one end of the arc panel is connected to the outer of the portion of screwing Wall, the other end of the arc panel are connected to the outer wall of hand-held part, and the inclined-plane of the stiffening plate is fixed on arc panel and and arc The shape of shape plate matches.

The utility model, further, the hand-held part, screw portion, stiffening plate, metal nuts, arc panel be one at Type setting.

The utility model has the following beneficial effects: being cooperated with upper beam ring, using the structure of the utility model by the upper of filter Cover lock is solid tighter, firm；Using the utility model when screwing, structure is stronger, transmits bigger torque, and service life is more It is long；Arc-shaped through-hole is arranged between adjacent groove simultaneously to be used to wear adhesive tape, during later maintenance, when being screwed, The medical fluid of contamination is contacted with adhesive tape, and medical fluid directly etching is avoided to screw handle, so that adhesive tape is only needed to change, without entirely screwing hand Handle replacement, reduces the cost of later maintenance.

Specific embodiment

The utility model is described in further detail in the following with reference to the drawings and specific embodiments, is not that this is practical Novel practical range is confined to this.

Beam ring cooperates on the present embodiment and integral type, for the upper cover of filter to be locked, as shown in Figure 1 to Figure 2, this A kind of filter described in embodiment screws handle, including circular hand-held part 1 and for screwing with what the external world was connect Portion 2, it is described to screw that portion 2 is cylindrical, the hand-held part 1 and screwing be arranged at equal intervals between portion 2 three triangles plus Strong plate 3, for transmitting torque, the outer wall of the hand-held part 1 is equipped with arc-shaped groove 11 at equal intervals, convenient for when screwing, hand It is held on hand-held part 1, gripping is stronger, transmits bigger torque, avoids hand from screwing and slipping phenomenon occur, described to screw portion 2 Equipped with central through hole 21 and metal nuts 4 are nested with, the axis of the metal nuts 4 is overlapped with the axis of the central through hole 21 Setting, and the internal diameter of the metal nuts 4 is equal to the internal diameter of central through hole 21, screwed using metal nuts 4 with screw it is stronger, It is not in stripped thread, compared to screw thread made of other materials, the service life is longer for screw thread in conjunction with more reliable；It is adjacent described Arc-shaped through-hole 12 is set between groove 11, and the arc-shaped through-hole 12 is for wearing adhesive tape, and when assembling, adhesive tape is sequentially passed through arc Through-hole 12 is fitted in adhesive tape a part in groove 11, and when being screwed, hand is fitted in adhesive tape and is screwed, and is filtering During machine later maintenance, since medical fluid has corrosivity, when locking filter upper cover, medical fluid can be infected with by screwing handle, be led to It crosses and is arranged after several arc-shaped through-holes 12 wear adhesive tape, medical fluid corrodes adhesive tape, and medical fluid directly etching is avoided to screw handle, medicine After corrosion adhesive tape, adhesive tape is only needed to change, without entirely screwing handle replacing, reduces later maintenance cost.

As shown in Figure 1 to Figure 2, on the basis of based on the above embodiment, further, 4 bottom end of metal nuts and rotation Twist portion 2 bottom end be in different planes, i.e., have between 4 bottom end of metal nuts and the bottom end for screwing portion 2 transition away from From, for screw guiding, limit, conducive to screwing for screw and metal nuts 4, specifically, when screwing handle and carrying out screwing fixed, Screw first protrudes into central through hole 21, is then threadedly coupled again with metal nuts 4.

It as shown in Figure 1 to Figure 2, further include three arc panels 5 further on the basis of based on the above embodiment, it is described One end of arc panel 5 is connected to the outer wall in the portion of screwing 2, and the other end of the arc panel 5 is connected to the outer wall of hand-held part 1, described The inclined-plane of stiffening plate 3 is fixed on arc panel 5 and matches with the shape of arc panel 5, and structure is stronger, transmits bigger power Square keeps the upper cover fixation of filter more firm.

As shown in Figure 1 to Figure 2, on the basis of based on the above embodiment, further, the hand-held part 1 screws portion 2, adds Strong plate 3, metal nuts 4, arc panel 5 are to be integrally formed setting, and structure is stronger, transmit bigger torque, make the upper of filter Lid fixation is more firm.

Using the structure of the present embodiment, cooperate with upper beam ring, the upper cover locking of filter is tighter, firm；Using this reality Example is applied when screwing, structure is stronger, transmits bigger torque, and the service life is longer.

The above is only a preferred embodiment of the utility model, therefore all according to the utility model patent application range institute The equivalent change or modification that the structure, feature and principle stated is done, in the protection scope of the utility model patent application.
