Detailed description of the invention
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are for illustrating that this utility model is not limited to limit scope of the present utility model.The implementation condition used in embodiment can do adjustment further according to the condition of concrete producer, and not marked implementation condition is usually the condition in normal experiment.
Embodiment one:
Figures 1 and 2 show that this dosing pump of this utility model back and forth drives a specific embodiment of returning device, this device includes: casing 1, in being located at casing 1 and can the most reciprocating reciprocating motion device 2, being located at interior the contact with reciprocating motion device 2 of casing 1 coordinates and can drive upon its rotation reciprocating motion device 2 to make fore-and-aft direction reciprocating eccentric drive device 3, and is fixed on described casing 1, is connected with described eccentric drive device 3, with the motor 4 driving eccentric drive device 3 to rotate.Described reciprocating motion device 2 has that to stretch out described casing 1 outer, for the reciprocating barrier film/plunger actuation axle 2a of the barrier film or plunger 8 that drive dosing pump.
In this example, described eccentric drive device 3 is made up of an eccentric shaft and multiple ball bearings of being enclosed within this eccentric shaft.
During work, motor 4 energising runs, eccentric drive device 3 is driven to rotate, the eccentric structure utilizing eccentric drive device 3 designs, when eccentric drive device 3 rotates, drive and contact the reciprocating motion device 2 of cooperation to make straight line reciprocating, so that barrier film/plunger actuation axle 2a drives the barrier film of dosing pump or plunger to make straight reciprocating motion, thus the suction of fluid and discharge in controlling pump.
Above-mentioned this dosing pump is also back and forth driven the structure of returning device to carry out further optimization by this example, particularly as follows: as shown in Figure 1, described reciprocating motion device 2 includes being enclosed within outside described eccentric drive device 3, and the ring set 2b coordinated is contacted with this eccentric drive device, described barrier film/plunger actuation axle 2a is connected on front side of the outside of this ring set 2b, the inner back side of described ring set 2b is threaded to be had one axle 2a is coaxially arranged with described barrier film/plunger actuation, and the return regulation screw 5 matched with described eccentric drive device 3, described casing 1 is outside equipped with and is connected with described return regulation screw 5 by driving connecting rod 6, for return regulation screw 5 described in turn to regulate the adjusting handle 7 of described return regulation screw 5 position.
When application, manual rotation adjusting handle 7 thus by driving connecting rod 6 drive return regulation screw 5 rotate, return regulation screw 5 changes the threaded engagement degree of depth between itself and ring set 2b after rotating, namely change the distance (the most just changing the distance between return regulation screw 5 and eccentric drive device 3 axial line) between return regulation screw 5 and ring set 2b center, with for eccentric adjustment stroke, thus regulate uninterrupted.When adjusting handle is in time turning clockwise, return regulation screw 5 moves near eccentric drive device 3, and stroke becomes big, and flow becomes big；When adjusting handle turns counterclockwise, return regulation screw 5 moves away from eccentric drive device 3, and stroke diminishes, and flow diminishes.
As depicted in figs. 1 and 2, in this example, described driving connecting rod 6 is made up of body of rod 6a and the spacer pin 6b being located on the bar wall of this body of rod 6a.Offer axially extended axle center hole in described return regulation screw 5, and on the hole wall of this axle center hole, offer axially extended line channel.Slide and be inserted in described axle center hole in one end of described body of rod 6a, and described spacer pin 6b slides and is embedded in described line channel.The other end of described body of rod 6a is fixed on described adjusting handle 7.
Described casing 1 is by the box-like body 1a of open topped and is bolted on the box cover 1b of described open-mouth and constitutes, and described motor 1 is vertically fixed on described box cover 1b by bolt.
Embodiment two:
Fig. 3 shows that this dosing pump of this utility model back and forth drives another specific embodiment of returning device, in this example, the structure of this device is essentially identical with the structure of embodiment one, it is only that in place of difference: eccentric drive device 3 and motor 4 in this example are horizontally disposed, uses horizontal type structure.And eccentric drive device 3 and the motor 4 in embodiment one is vertically arranged, use vertical structure.
Certainly, above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow people will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations done according to the spirit of this utility model main technical schemes or modification, all should contain within protection domain of the present utility model.
