Abstract
The utility model discloses a rubber cloth diaphragm, which comprises a connecting hole, a diaphragm body, a connecting rod extending upwards from the diaphragm body, and a connecting body extending downwards from the diaphragm body; the diaphragm further comprises cloth, and the cloth is radially accommodated in the diaphragm body and the connecting rod; and the connecting rod and the diaphragm body are connected and form an included angle which is less than 180 degrees. When the rubber cloth diaphragm is applied to the occasion needing connection and compression, a connecting hole is meshed with a foreign object, the diaphragm body, the connecting body and the connecting rod are tightly fitted with the outline of the foreign object, and the connecting rod is contacted with the foreign object to form an inwardly-squeezing shape, so that the fitness is good; and the cloth is accommodated in the diaphragm body and the connecting rod, so that the toughness of the diaphragm can be enhanced, and the diaphragm is not easy to deform, strong in fatigue strength and good in durability.
Description
Technical field
The utility model relates to design and the manufacturing of mould, is specifically related to a kind of canvas filler rubber diaphragm.
Background technology
Rubber diaphragm is mainly used in the valve, control valve, automation hunting gear, switch sum counter of flow, pressure, differential, liquid level, the compensation of thermostat accumulated heat etc.It is advantageous that functional reliability is high, plyability good, long working life, cost is low.
Folder cloth is strengthened diaphragm and especially is widely used in the high pressure occasion, its larger power, plyability that can produce is higher, long service life, can accurately synchronize with other Control Component executable operations, guarantee the winding-up of pulse compression air, even under very abominable condition of work, also can guarantee its normal operation and long service life, be conducive to simultaneously increase the economic benefit of even elastic construction.
The structure of existing folder cloth diaphragm is generally: be made of diaphragm body and the connecting hole that is positioned at diaphragm body center, its free end is the notch cuttype structure, the end is provided with external screw thread and its diameter of axle less than the gonnecting rod body aperture, and interlinking lever end passes the connecting hole of diaphragm and with nut, pressing diaphragm fastened and is installed on diaphragm connecting rod free end.
But diaphragm easily produces plastic deformation because of pressurized, it is that connecting rod fixedly mounts the phenomenon that exists stress to concentrate on the periphery of position, and the effect that also can receive alternation moment, because the diaphragm body is thinner, very easily cause damage in the position that stress is concentrated, thereby cause diaphragm to work.
The utility model content
In order to solve the problems of above-mentioned existence, the utility model aims to provide and a kind ofly should not damage when being fixed, fatigue resistance is strong, the canvas filler rubber diaphragm of good endurance.
The utility model provides a kind of canvas filler rubber diaphragm, comprises connecting hole, diaphragm body, extends upward the connecting rod that forms and the connector that forms to downward-extension from described diaphragm body from described diaphragm body.
And described canvas filler rubber diaphragm also comprises folder cloth, and described folder cloth radially is placed in described diaphragm body and described connecting rod.
Wherein, described connecting rod also forms to downward-extension after described diaphragm body extends upward again, and described connecting rod is angle with described diaphragm body and is connected.
Preferably, described angle is less than 180 degree.
When the described canvas filler rubber diaphragm that the utility model provides is applied to need to connect the occasion that compresses, described connecting hole and foreign object engagement, the profile of described diaphragm body, connector and connecting rod and foreign object fits tightly, described connecting rod consists of inwardly extruding shape with contacting of foreign object, and stickiness is good thus; And be equipped with described folder cloth in described diaphragm body and described connecting rod, can strengthen the toughness of described diaphragm, not yielding, fatigue resistance is strong, good endurance.
Description of drawings
Fig. 1 is the cutaway view of a kind of canvas filler rubber diaphragm of the utility model the first embodiment;
Fig. 2 is the cutaway view of a kind of canvas filler rubber diaphragm of the utility model the second embodiment.
The drawing reference numeral explanation
1 diaphragm body 2 connecting rod 3 connectors
4 connecting hole 5 folder cloth
The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment:
Please refer to Fig. 1, the first embodiment of a kind of canvas filler rubber diaphragm that provides for the utility model comprises connecting hole 4, diaphragm body 1, extends upward the connecting rod 2 that forms and the connector 3 that forms to downward-extension from described diaphragm body 1 from described diaphragm body 1.Described canvas filler rubber diaphragm also comprises folder cloth 5, and described folder cloth 5 radially is placed in described diaphragm body 1 and described connecting rod 2.
Wherein, described connecting rod 2 specifically forms to downward-extension after described diaphragm body 1 extends upward again, and described connecting rod 2 is angle with described diaphragm body and is connected, and described angle is less than 180 degree.
Canvas filler rubber diaphragm structure in the second embodiment that the utility model provides in canvas filler rubber diaphragm structure and the first embodiment is similar, this paper repeats no more this, and the described canvas filler rubber diaphragm in the second embodiment is particularly useful for two foreign objects connections and has the poor occasion of certain altitude.
When the described canvas filler rubber diaphragm that the utility model provides is applied to need to connect the occasion that compresses, described connecting hole 4 and foreign object engagement, described diaphragm body 1, connector 3 fit tightly with the profile of connecting rod 2 with foreign object, described connecting rod 2 consists of inwardly extruding shape with contacting of foreign object, and stickiness is good thus; And be equipped with described folder cloth in described diaphragm body 1 and described connecting rod 2, can strengthen the toughness of described diaphragm, not yielding, fatigue resistance is strong, good endurance.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obvious realization of the present utility model is not subject to the restrictions described above; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all in protection domain of the present utility model.
Claims (3)
1. canvas filler rubber diaphragm, comprise connecting hole, diaphragm body, extend upward the connecting rod that forms and the connector that forms to downward-extension from described diaphragm body from described diaphragm body, it is characterized in that, also comprise folder cloth, described folder cloth radially is placed in described diaphragm body and described connecting rod.
2. canvas filler rubber diaphragm according to claim 1, is characterized in that, described connecting rod from described diaphragm body upwards and form to downward-extension, and described connecting rod is angle with described diaphragm body and is connected.
