Abstract
A pump head fixed connection structure of a diaphragm pump according to the utility model comprises a front cover of electric motor and an external cover of pump head. An external cover connector is provided between the front cover of electric motor and the external cover of the pump head. The external cover of pump head, the external cover connector and the front cover of electric motor are connected through thread fasteners which are screw-connected with the front cover of electric motor. The front cover of electric motor is provided with a nut matched with the thread fastener. Through the rigid matching and connection between the thread fastener and the nut, the fixed connection between the external cover of the pump head of the diaphragm pump and the front cover of the electric motor can be realized, and the stability and pressure resistance of the structure are greatly increased. Furthermore, through the technical scheme, the front cover of the electric motor can be changed for a plastic piece in production. The production cost of the diaphragm is greatly reduced and the production efficiency of the product is increased.
Description
Technical field
The utility model relates to a kind of linkage structure of diaphragm pump, is the pump head fixed connection structure of diaphragm pump specifically.
Background technique
The diaphragm pump of RO water purification machine special use in the market, the pump head fixed connection structure of its diaphragm pump generally comprises between motor protecgulum and pump head enclosing cover, motor protecgulum and the pump head enclosing cover and is provided with outer lid attachments, pump head enclosing cover, outer lid attachments and motor protecgulum three are fixing by threaded fastener (industry claims the machine silk), and fastening piece is threaded with the motor protecgulum.The material that the motor protecgulum 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 pump head fixed connection structure of diaphragm pump, comprise between motor protecgulum and pump head enclosing cover, motor protecgulum and the pump head enclosing cover and be provided with outer lid attachments, pump head enclosing cover, outer lid attachments and motor protecgulum three fix by threaded fastener, fastening piece is threaded with the motor protecgulum, it is characterized in that: described motor protecgulum is provided with the nut that matches with threaded fastener.
All have the positioning hole that matches with threaded fastener on described pump head enclosing cover, outer lid attachments and the motor protecgulum.
Described nut is embedded in the positioning hole of motor protecgulum.
Described motor protecgulum is a working of plastics.
The utility model improves the pump head fixed connection structure of the diaphragm pump of prior art, on the motor protecgulum, be inlaid with nut, rigidity by threaded fastener and nut is connected, pump head enclosing cover and the motor protecgulum 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, the motor protecgulum 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 pump head fixed connection structure of diaphragm pump of the present utility model, comprise and be provided with outer lid attachments 3 between motor protecgulum 1 and pump head enclosing cover 2, motor protecgulum 1 and the pump head enclosing cover 2, pump head enclosing cover 2, outer lid attachments 3 and motor protecgulum 1 three are fixing by threaded fastener 4 (industry claims the machine silk), and fastening piece is threaded with motor protecgulum 1.Motor protecgulum 1 described in the utility model is provided with the nut 5 that matches with threaded fastener 4, and, all have the positioning hole 6 that matches with threaded fastener 4 on pump head enclosing cover 2, outer lid attachments 3 and the motor protecgulum 1, nut 5 is embedded in the positioning hole 6 of motor protecgulum 1.In addition, in the utility model, motor protecgulum 1 is a working of plastics.The utility model is connected by the rigidity of threaded fastener 4 with nut 5, can realize that the pump head enclosing cover 2 of diaphragm pump is fastenedly connected with motor protecgulum 1, and this stability of structure and resistance to pressure are improved greatly; And motor protecgulum 1 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.
