Abstract
The utility model discloses an outer pressing plate applied to a diaphragm pump, and belongs to the technical field of diaphragm pumps. The outer pressing plate applied to the diaphragm pump comprises a plate body and a connector connected with the plate body, wherein an annular protruding structure is arranged at the top of the end, connected inside the plate body, of the connector. By means of the technical scheme, the outer pressing plate applied to the diaphragm pump has the advantages that a bolt and the plate body are fixed through the annular protruding structure, the bolt keeps connected with the plate body under a high work intensity condition, the probability of damage to the diaphragm pump caused by damage to the outer pressing plate is reduced, and the work stability of the diaphragm pump is improved.
Description
Technical field
The utility model relates to diaphragm pump technical field, relates in particular to a kind of outer plate that is applied to diaphragm pump.
Background technique
Traditional outer plate that is applied to diaphragm pump, is arranged at diaphragm outside conventionally, and in the middle of diaphragm being clipped in conjunction with the inner clip plate that is arranged at diaphragm inner side, the basic structure of outer plate as shown in Figure 1-2:
As shown in Figure 1, whole outer plate comprises pressing plate 11 and the stainless screw bolt 12 of aluminum alloy, has a bolt hole 111 in the one side that pressing plate 11 is connected with bolt 12, and bolt hole 111 inside are provided with the screw thread mating with bolt 12.When connecting, on bolt 12, scribble special glue, and be screwed in the bolt hole 111 of pressing plate 11, to form a complete outer plate (as shown in Figure 2).
But, above-mentioned linkage structure is in the situation that working strength is very large, for example, when diaphragm pump is worked under high-intensity operating mode, the action of reciprocating sliding frequently due to diaphragm and center link rod, easily cause the sliding tooth of bolt 12, even can cause in some cases whole bolt 12 to be pulled out from pressing plate 11.
Chinese patent (CN202451404U) discloses a kind of membrane pump with pneumatic drive outer plate that relates to pneumatic pump accessory field, the plate body that outer plate comprises stainless steel and bolt; The middle part of plate body inner side is provided with circular groove, and the outer side center position of plate body is provided with the through hole that is through to bottom portion of groove center; The aperture that through hole is positioned at plate body outside is greater than the aperture that through hole is positioned at plate body inner side, and the aperture tapering of through hole is 0.005～0.01; Bolt-through through hole rear nut is positioned at the place, through hole aperture in plate body outside, and bolt tapering is corresponding with the tapering of through-hole aperture; Outer plate can avoid occurring the whole phenomenon of damaging in the action of reciprocating sliding frequently, the also corresponding working efficiency that improves membrane pump with pneumatic drive when effectively reducing membrane pump with pneumatic drive maintenance cost.Technique scheme has still adopted the threaded bolt of tool to be connected with outer plate, cannot fundamentally solve the sliding tooth of bolt and cause the problem being pulled out.
Summary of the invention
According to problems of the prior art, a kind of outer plate that is applied to diaphragm pump is now provided, specifically comprise:
An outer plate that is applied to diaphragm pump, is characterized in that, comprises plate body and the link being connected with described plate body;
The top, one end being connected on described link in described plate body is provided with the outstanding structure of an annular.
Preferably, the outer plate that this is applied to diaphragm pump, is characterized in that, described link comprises the remainder not being connected in described plate body.
Preferably, the outer plate that this is applied to diaphragm pump, is characterized in that, described link is bolt;
Described remainder is provided with screw thread.
Preferably, the outer plate that this is applied to diaphragm pump, is characterized in that, the cross section of the projection of the outstanding structure of described annular is rectangle.
Preferably, the outer plate that this is applied to diaphragm pump, is characterized in that, described link is connected with described plate body casting.
The beneficial effect of technique scheme is: adopt the outstanding structure fixing bolt of annular and plate body, make bolt keep being connected with plate body under high workload intensity, reduce the probability that causes diaphragm pump to damage because of outer plate breakage, promote the stability of diaphragm pump work.
Accompanying drawing explanation
Fig. 1-2 is outer plate structural representation of the prior art;
Fig. 3-4th, in preferred embodiment of the present utility model, the structural representation of novel outer plate.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
As shown in Figure 3, in preferred embodiment of the present utility model, a kind of outer plate that is applied to diaphragm pump, comprises plate body 31 and link 32.In preferred embodiment of the present utility model, plate body 31 is connected with link 32.
In preferred embodiment of the present utility model, the top, one end that is connected in plate body 31 inside at link 32 is provided with the outstanding structure of an annular.In preferred embodiment of the present utility model, as shown in Figure 3, this annular projection structure is comprised of the first pontes 321 and the second attachment portion 322, wherein the first pontes 321 is arranged at 322 tops, the second attachment portion, be in preferred embodiment of the present utility model, the first pontes 321 is the projection of the outstanding structure of annular.Further, according to foregoing description, the ledge structure that the first pontes 321 and the second attachment portion 322 form as shown in Figure 3.
Further, in preferred embodiment of the present utility model, the first pontes 321 is that the cross section A of projection is rectangle.The outstanding structure of annular is square toes type structure, while being connected to like this plate body inside, is difficult to be rotated under intensive work environment, is therefore difficult to depart from and be pulled out with plate body.
In preferred embodiment of the present utility model, above-mentioned link 32 is connected for casting with the Placement of plate body 31, and the outstanding structure (the first pontes 321 and the second attachment portion 322) of the annular of link 32 is watered and cast from plate body 31.
In preferred embodiment of the present invention, the not whole casting of above-mentioned link 32 plate body 31 inside, link 32 comprises the remainder 323 not being connected in plate body 31.
Further, in preferred embodiment of the present utility model, in order to facilitate outer plate to connect diaphragm and center link rod, link can be bolt, and correspondingly, above-mentioned remainder 323 is provided with screw thread, to connect outside diaphragm and center link rod.
In preferred embodiment of the present utility model, because bolt is generally cylindrical, therefore above-mentioned the second attachment portion 322 is cylindrical, and remainder 323 is also cylindrical.
Be illustrated in figure 4 in preferred embodiment of the present utility model the complete outer plate structure that adopts above-mentioned plate body 31 and link 32 to form.
In sum, goal of the invention of the present utility model is: by the top with link, be set to annular projection structure (can be preferably square toes type ledge structure), the relative rotation and the relative sliding that stop link and plate body, thereby stop link under high-intensity working environment to be deviate from from plate body, be applicable to operate under the operating mode of various intensity.
The foregoing is only the utility model preferred embodiment; not thereby limit mode of execution of the present utility model and protection domain; to those skilled in the art; should recognize that being equal to that all utilization the utility model specifications and diagramatic content done replace and the resulting scheme of apparent variation, all should be included in protection domain of the present utility model.
