Embodiment
Diaphragm pump in the present embodiment comprises arc diaphragm 1, fork 2, pressing plate 3, screw 4, the pump housing 5, and parts such as cylinder body 6.
Arc diaphragm and securing means part-structure as shown in Figure 1, arc diaphragm 1 from-inner-to-outer is made of central part 1C, variant part 1B, sealed department 1A successively, central part is a horizontal plane, the center is provided with fixed hole 1D, variant part is an arc shaped surface.
Securing means comprises the pressing plate 3 that is located at below the diaphragm and is located at fork 2 above the diaphragm, and location open tubular column 3D is equipped with at the pressing plate center, and open tubular column bottom opening broad is as screw perforation 3C; Fork bottom centre is provided with spacing positioning hole 2D, and positioning hole top narrows down, as screw position 2C; The location open tubular column passes the fixed hole of arc diaphragm, inserts in the spacing positioning hole of fork; One screw 4 passes the location open tubular column of pressing plate, the spacing positioning hole of insertion fork, and pressing plate, arc diaphragm and fork are fastenedly connected.
This partial devices is combined arc diaphragm 1, fork 2 and pressing plate 3 and screw 4 when mounted, three parts is suppressed made whole together by screw 4 (this screw can be made self tapping screw or machine tooth screw according to the requirement of product).
Concrete installation steps are as follows: at first fork 2 is put into special anchor clamps the inside (product swing or rotation when avoiding completed knocked down products), 3D locating column in the pressing plate 3 is passed 1D positioning hole in the arc diaphragm 1, with arc diaphragm 1 location, 3D locating column in the integral body of the arc diaphragm 1 that assembles and pressing plate 3 is inserted in the spacing positioning hole of 2D in the fork 2, screw 4 is squeezed into to assemble in the 2C screw position in the fork 2 finish.After this assembling is finished, arc diaphragm 1 and fork 2 are because the pulling force of screw, position of bone 3B in the pressing plate 3 and the position of bone 2A in the fork 2 tightly push down central part 1C and small part variant part 1B in the arc diaphragm 1, surface of contact 2B in central part 1C and the fork 2 in the arc diaphragm 1 and the surface of contact 3E in the pressing plate 3 are contacted form vacuum, be allowed to condition in the movement process balanced the pull power of arc diaphragm 1 motion when stressed of sharing, be convenient to be anchored on other two parts, owing to stressed even, can increase the working life and the sealing of arc diaphragm.
Locating column 3D in the pressing plate 3 has location and spacing function, senior general's arc diaphragm 1 extrusion-deformation of can avoiding exerting oneself, and perhaps exerting oneself in 4 o'clock because of screwing inadequately can not secure component.Owing to used the arc diaphragm of the radian identical with cylinder body 6, pressing plate 3 with identical radian measure, when moving, can effectively improve product the life-span and the performance of product, because the arc of arc diaphragm 1 is arranged, the operation amplitude of the arc diaphragm just changes arc diaphragm 1 when to-and-fro motion radian during with to-and-fro motion is consistent, and referring to Fig. 2, Fig. 3, it is folding that arc diaphragm 1 is produced, stretch, increased substantially the life-span of arc diaphragm 1.During pressing plate 3 designs, the orthographic projection of bottom surface 3A in cylinder body 6 bottoms will pass in and out valve 6A and cover fully, when whole parts in when operation, the gas force bearing point will be positioned on the pressing plate 3, rather than above the soft arc diaphragm in the market, can improve performance parameter like this, because pressing plate 3 adopts hard material, indeformable when stressed, arc diaphragm 1 and fork 2 and pressing plate 3 contact position all need certain arc, the arc size avoids product the arc diaphragm not to be pulled and punctured in running according to the actual conditions design of product.
With arc diaphragm 1, fork 2 and pressing plate 3 and screw 4 are combined, the pump housing 5 and cylinder body 6 are fitted together as shown in Figure 3, this moment, the arc diaphragm 1 of pump was in lowest order, gas in the cylinder body or liquid are when the operation one-period, the vacant few more performance that obtains in space high more (under equal conditions) in the cylinder body, because the arc of the arc fundamental sum pump housing of the arc of arc diaphragm 1 and pressing plate 3 is suitable, the remaining space of the inside is quite few when pump operation arrives lowest order, and the design that is compared to other just can increase substantially the performance of product.As shown in Figure 4, because the arc of arc diaphragm 1, arc diaphragm 1 does not need to stretch, and just with arc-shaped deformation, has reduced the vibration and the noise of pump with this when arc diaphragm 1 is in highest order.The orthographic projection of pressing plate 3 bottom surface 3A in cylinder body 6 bottoms will pass in and out valve 6A and cover fully, when whole parts in when operation, the gas force bearing point will be stressed on pressing plate 3, rather than above the soft arc diaphragm 1, the performance of pump in the operation one-period be can improve like this, can moment more gas or liquid in one-period, be extracted or extrude out.
Above disclosed only is a kind of preferred embodiment of the utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
