Abstract
A diaphragm fixed connection structure of a diaphragm pump according to the utility model comprises an impeller which is used for the fixed connection of the diaphragm. The diaphragm is provided with a water-pressing piston sheet. The diaphragm, the impeller and the water-pressing piston sheet are fixed through the thread fastener. The impeller is provided with a nut which is matched with the thread fastener and is inserted in the impeller. The impeller is a plastic piece. The utility model can realize the fastening connection between the diaphragm of the diaphragm pump and the impeller and greatly increases the stability and pressure resistance of the structure. Furthermore, the impeller can be replaced by a plastic piece in production, thereby greatly reducing the production cost of the diaphragm pump and facilitating the production and generalization of the product.
Description
Technical field
The utility model relates to a kind of linkage structure of diaphragm pump, is the diaphragm fixed connection structure of diaphragm pump specifically.
Background technique
The diaphragm pump of RO water purification machine special use in the market, the diaphragm fixed connection structure of its diaphragm pump generally comprises and is used for the hard-wired driving member of diaphragm, diaphragm is provided with setting-out piston sheet, and diaphragm, driving member and setting-out piston sheet three connect by threaded fastener (industry claims the machine silk).The material that described pushing piece uses is two kinds in aluminium material or plastics normally.The aluminium material has stable molding, hardness is big, compact dimensions is accurate and make characteristics such as bolt is connected firmly, but cost is higher, manufacturing efficiency is low; And plastics have characteristics such as cost is low, manufacturing efficiency height, but be connected with bolt insecure, cause overall structure not withstand voltage, product quality problem appears.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the diaphragm fixed connection structure of the diaphragm pump that provide a kind of and be connected firmly, cost is low.
Goal of the invention of the present utility model is achieved in that a kind of diaphragm fixed connection structure of diaphragm pump, comprise and be used for the hard-wired driving member of diaphragm, diaphragm is provided with setting-out piston sheet, diaphragm, driving member and setting-out piston sheet three fix by threaded fastener, threaded fastener is threaded with driving member, it is characterized in that: described driving member is provided with the nut that matches with threaded fastener.
All have the mounting hole that matches with threaded fastener on described diaphragm, driving member and the setting-out piston sheet.
Described nut is embedded in the mounting hole of driving member.
Described driving member is a working of plastics.
The utility model improves the diaphragm fixed connection structure of the diaphragm pump of prior art, on driving member, be inlaid with nut, rigidity by threaded fastener and nut is connected, diaphragm and the driving member that can realize diaphragm pump are fastenedly connected, and this stability of structure and resistance to pressure are improved greatly; And by this technological scheme, pushing piece can change working of plastics into when producing, greatly reduce the cost of production of diaphragm pump, has improved production efficiency of products.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Accompanying drawing 2 is the utility model embodiment's a sectional structure chart.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in Figure 2 according to Fig. 1, the diaphragm fixed connection structure of diaphragm pump of the present utility model comprises being used for diaphragm 1 hard-wired driving member 2 that diaphragm 1 is provided with setting-out piston sheet 3, and fixing, threaded fastener 4 (industry claims the machine silk) is threaded with driving member.Driving member 2 described in the utility model is provided with the nut 5 that matches with threaded fastener 4, and, all having the mounting hole 6 that matches with threaded fastener on diaphragm 1, driving member 2 and the setting-out piston sheet 3, nut 5 is embedded in the mounting hole 6 of driving member 2.In addition, in the utility model, driving member 2 is a working of plastics.The utility model is connected by the rigidity of threaded fastener 4 with nut 5, can realize that the diaphragm 1 of diaphragm pump is fastenedly connected with driving member 2, and this stability of structure and resistance to pressure are improved greatly; And pushing piece 2 can change working of plastics into when producing, greatly reduce the cost of production of diaphragm pump, and the production that is beneficial to product is promoted.
