Abstract
The utility model relates to a locking yoke of the intermediate rod and the piston rod for a diaphragm pump, belonging to the technical field of devices for fastening or fixing members or machine parts, particularly relates to a locking yoke of the intermediate rod and the piston rod for a diaphragm pump. The utility model provides a small-volume and low-cost locking yoke of the intermediate rod and the piston rod for a diaphragm pump. The locking yoke comprises an upper half yoke and a lower half yoke, and is structurally characterized in that the longitudinal sections of the upper half yoke and the lower half yoke are both semi-ring-shaped, the four corners of the upper half yoke are provided with recesses, and through-holes are disposed at the recesses; and the four corners of the lower half yoke are provided with threaded holes corresponding to the through-holes.
Description
Technical field
the utility model belongs to the device technology field that fastening or fixed component or machine parts are used, and relates in particular to the locking clip of a kind of diaphragm pump with Jie's bar and piston rod.
Background technique
piston rod is the link between piston and the crosshead, and promptly one in piston rod is connected with piston, and the other end is connected with crosshead.Diaphragm pump divides two sections with piston rod, still claims piston rod for one section that is connected with piston, and one section that is connected with crosshead is called Jie's bar.Piston rod is divided into the mode of two sections installations, has the maintenance convenient disassembly, save advantage such as easily damaged parts.
The general split-type clip that adopts is locked between
piston rod and Jie's bar, and this mode dismantles, easy for installation, quick.But also there are some shortcomings in existing split-type clip, and is as shown in Figure 5, and it is through the clamping plate 101 and fastening piece 102 lockings at two ends, and clamping plate 101 will take certain volume like this, so installing space is big; And processing is easy inadequately, and cost is higher.
Summary of the invention
the utility model is exactly to the problems referred to above, and a kind of volume is little, cost the is low diaphragm pump locking clip with Jie's bar and piston rod is provided.
are for realizing above-mentioned purpose; The utility model adopts following technological scheme, and the utility model comprises first clip and second clip, and the longitudinal section of first clip of its structure outline and second clip is semi-round ring shape; Four jiaos of first clip have depression, and recess has through hole; Four jiaos of second clip are provided with tapped hole corresponding to said through hole.
as a kind of preferred version, front portion, the rear portion of the front portion of said first clip inwall of the utility model, rear portion and second clip inwall are provided with the conical surface.
the utility model beneficial effect: the longitudinal section of first clip of the utility model and second clip is semi-round ring shape, and four jiaos of first clip have depression, and recess has through hole; Four jiaos of second clip are provided with tapped hole corresponding to said through hole; Need not the clamping plate at existing locking clip two ends, so the utility model volume is littler, compact structure, attractive in appearance has reduced installing space; And can be directly through the bar machine shaping of circle, cost is low.
Description of drawings
further specify the utility model below in conjunction with accompanying drawing and embodiment.The utility model protection domain not only is confined to the statement of following content.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the plan view of Fig. 1.
Fig. 4 is the user mode figure of the utility model.
Fig. 5 is the structural representation of existing locking clip.
Among
figure, 1 be that second clip, 2 is fastening piece for clamping plate, 102 for piston rod, 101 for Jie's bar, 9 for the conical surface, 8 for first clip, 7 for screw, 6 for depression, 5 for through hole, 4 for tapped hole, 3.
Embodiment
are as shown in the figure, and the utility model comprises first clip 6 and second clip 1, and the longitudinal section of first clip 6 and second clip 1 is semi-round ring shape, and four jiaos of first clip 6 have depression 4, and 4 places of caving in have through hole 3; Four jiaos of second clip 1 are provided with tapped hole 2 corresponding to said through hole 3.
Front portion, the rear portion of front portion, rear portion and second clip 1 inwall of
said first clip 6 inwalls are provided with the conical surface 7; Rely on the conical surface 7 lockings, locking property is good.
are below in conjunction with the using process of description of drawings the utility model: at first Jie's bar 8 is linked to each other with piston rod 9 butt joints; Buckle half clip 6 and second clip 1 then, first clip 6 is put together on together with second clip 1 through through hole 3 and tapped hole 2 with screw 5 at last; So just, Jie's bar 8 and piston rod 9 are coupled together, and locking.
it is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technological scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
