Abstract
The utility model discloses a diaphragm fixing structure for a booster pump. The diaphragm fixing structure comprises a diaphragm and a transmission mechanism; the surface of the diaphragm protrudes to form a fixing bolt; the fixing bolt comprises a sealing portion, a pull rod portion and a reversed hook portion; the pull rod portion protrudes to form at the center of the sealing portion; the reversed hook portion is formed at the tail end of the pull rod portion; the transmission mechanism comprises a through hole which is corresponding to the pull rod portion to be formed; one end of the through hole is provided with a sealing groove which is communicated with the through hole and is corresponding to the sealing portion to be formed; the other end of the through hole comprises an abutting portion. According to the diaphragm fixing structure for the booster pump, the integration of the diaphragm and a piston is achieved; the structure is simplified and accordingly the installation and fixation operation can be convenient; water leaking points formed in the process of diaphragm opening in the prior art are reduced and accordingly the leak-proof effect can be good.
Description
Technical field
The utility model relates to for water purifier suction booster technical field, particularly relates to a kind of suction booster diaphragm fixed structure.
Background technique
Carry out in the water purifier of purification of water quality in employing Reverse Osmosis Technology, suction booster sucks former water from water intake in the course of the work, by the pressurization of suction booster, water is increased to certain pressure and discharges.The diaphragm of suction booster and on piston, should play intact water buffer action, ensure again the smooth and easy of transmission, can make the motor driving shaft in the pump housing drive driving mechanism to produce axially reciprocating, and by repeatedly upwards pushing the piston diaphragm in the low pressure valve on piston valve base, water is clamp-oned to hyperbaric chamber from low pressure chamber, export with certain pressure.
Referring to Fig. 1 and Fig. 2, diaphragm 110 is made up of elastic plastic material conventionally, main body is triangular in shape, the through hole 121 of piston 120 equates with through hole 111 apertures of diaphragm 110, piston 120 is in diaphragm 110 upper surface location, through hole 121,111 alignment each other, more fixing with the driving mechanism 140 of below by screw 130.
But, in manufacture control process, easily there is screw and twist situation not in place or not tight, thereby cause this place's seal failure, cause and leak.In addition, adopt fastened by screw mode, operation is relatively inconvenient, and efficiency is lower.
Summary of the invention
For solving the deficiency existing in prior art, technical problem to be solved in the utility model is to provide a kind of suction booster diaphragm fixed structure easy for installation and enhancing leak preventing effect that operates.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of suction booster diaphragm fixed structure, comprise diaphragm and driving mechanism, described diaphragm surface is outstanding is formed with fixed bolt, and described fixed bolt comprises sealed department, rod section, barb portion, the outstanding sealed department central authorities that are formed at of described rod section, described barb portion is formed at rod section end; Described driving mechanism has the through hole of corresponding rod section moulding, and described through hole one end is provided with the seal groove with the corresponding sealed department moulding of its connection, and the other end has contact part.
Preferably, described sealed department is in the form of annular discs, and described rod section is cylindric, and described barb portion is coniform.
Preferably, described diaphragm main body is triangular in shape.
The beneficial effect of technical solutions of the utility model is:
A kind of suction booster diaphragm fixed structure of the present utility model, due to the outstanding fixed bolt that is formed with in described diaphragm surface, described fixed bolt comprises sealed department, rod section, barb portion, the outstanding sealed department central authorities that are formed at of described rod section, and described barb portion is formed at rod section end; Described driving mechanism has the through hole of corresponding rod section moulding, and described through hole one end is provided with the seal groove with the corresponding sealed department moulding of its connection, and the other end has contact part.Realize like this integrated of diaphragm and piston, not only simplified the structure, made to install fixing operation more convenient, and reduced the leakage point that the perforate of prior art diaphragm exists, made leak preventing effect better.

Embodiment
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
Embodiment:
As Fig. 3 and Fig. 4, a kind of suction booster diaphragm fixed structure of the present embodiment, comprises diaphragm 110 and driving mechanism 140.
Diaphragm 110 main bodys are equilateral triangle, the lower surface of diaphragm 110 be evenly distributed with three with driving mechanism 140 region coordinating that interfixes, the outstanding fixed bolt 112 that is formed with in substantial middle position in this each region.
As shown in Figure 5, fixed bolt 112 comprises sealed department 1121, rod section 1122 and barb portion 1123 from top to bottom successively.Sealed department 1121 entirety are in the form of annular discs, the outstanding substantial middle position that is formed at sealed department 1121 lower surfaces of rod section 1122, and rod section 1122 entirety are cylindric.The outstanding lower end that is formed at rod section 1122 of barb portion 1123, barb portion 1123 is coniform.The diameter of the conical surface of cone shape barb portion 1123 is greater than the diameter of the cylndrical surface of columned rod section 1122.
As shown in Figure 6, driving mechanism 140 is provided with seal groove 142, through hole 141 and contact part 143 from top to bottom successively.Sealed department 1121 moulding of the corresponding fixed bolt 112 of seal groove 142, rod section 1122 moulding of the corresponding fixed bolt 112 of through hole 141, the barb portion of the corresponding fixed bolt 112 in contact part 143 arranges, seal groove 142 is interconnected with through hole 141, and 143 belows, contact part are formed with the containing space of barb portion that can accommodating fixed bolt 112.
As shown in Figure 3 and Figure 4, the fixed bolt 112 of diaphragm 110 wears the through hole 141 of driving mechanism 140 downwards, because diaphragm 110 adopts soft materials, the barb portion 1123 of fixed bolt 112 is pressed through the through hole 141 of driving mechanism 140, thereafter, conflict mutually in the contact part 143 of the conical surface of barb portion 1123 and driving mechanism 140, diaphragm 110 is fixedly connected with driving mechanism 140.Now, the rod section 1122 of fixed bolt 112 and sealed department 1121 are mutually closely sealed with through hole 141 and the seal groove 142 of driving mechanism 140 respectively.
Above specific embodiment of the utility model is described.It will be appreciated that, the utility model is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
