Description
Technical field
The utility model relates to diaphragm technology fields, more specifically to oil sealing rolling diaphragm.
Background technique
One of the main distinction of diaphragm type cylinder and piston formula cylinder is exactly that the former active force changes with stroke size,
The active force of the latter is unrelated with stroke size.At initial position, at this moment compression area acts on diaphragm greatly without deforming
Power is also big, and with the increase of diaphragm displacement, active force is gradually reduced.Existing oil sealing rolling diaphragm is in carnival hat shape, is pressed from both sides by rubber
Nylon cloth composition, without the component of its supporting role, be not fixed easily, install, easily deform.
Therefore, how to solve the problems, such as existing oil sealing rolling diaphragm is inconvenient to install, is easily-deformable, becomes those skilled in the art
Member's important technological problems to be solved.
Utility model content
The purpose of this utility model is to provide oil sealing rolling diaphragms, are inconvenient to pacify to solve existing oil sealing rolling diaphragm
Dress, easily-deformable problem.
The purpose of this utility model is achieved through the following technical solutions:
Oil sealing rolling diaphragm is applied to diaphragm type cylinder, including diaphragm ontology, the both ends of the diaphragm ontology are equipped with out
Mouthful, two openings are equipped with the metalwork being used to support.
Preferably, the material of the diaphragm ontology is the rubber with nylon fiber cloth interlayer, and the metalwork setting exists
In the rubber.
Preferably, the diaphragm ontology includes cylindrical section, the extension with outward extension of the first end face of the cylindrical section
The junction of section, the extended segment and the first end face is equipped with changeover portion, and the first end face forms the first opening, the circle
The second end face of shell of column is equipped with the second opening.
Preferably, the changeover portion is in arc-shaped.
Preferably, second opening is equipped with circular protrusion.
Preferably, the second end face is equipped with fixation hole.
Preferably, when positive installation, there is netted lines in the outer surface of the diaphragm ontology, and inner surface is smooth surface, described interior
Surface is gas compression face.
In technical solution provided by the utility model, oil sealing rolling diaphragm is applied to diaphragm type cylinder, including diaphragm sheet
Body, the both ends of diaphragm ontology are equipped with opening, and two openings are equipped with the metalwork being used to support.So set, oil sealing is rolled
Dynamic diaphragm is scalable, folds, and is equipped with metalwork in two openings, plays a supporting role, be easily installed, fix, not variable
Shape, to solve the problems, such as that existing oil sealing rolling diaphragm is inconvenient to install, is easily-deformable.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment

Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of oil sealing rolling diaphragm in the embodiments of the present invention.
In Fig. 1:
1- cylindrical section, the extended segment 2-, 3- changeover portion, the circular protrusion of 4-.
Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model
Scheme is described in detail.Obviously, described embodiment is only a part of the embodiment of the utility model, rather than complete
The embodiment in portion.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work
Under the premise of obtained all other embodiment, belong to the range that the utility model is protected.
Present embodiment is designed to provide oil sealing rolling diaphragm, and it is inconvenient to solve existing oil sealing rolling diaphragm
Installation, easily-deformable problem.
Hereinafter, being illustrated referring to attached drawing to embodiment.In addition, embodiments illustrated below is not to recorded in claim
Utility model content rise any restriction effect.In addition, the full content of composition represented by following example is not limited to conduct
Necessary to the solution of utility model documented by claim.
Referring to FIG. 1, present embodiment provides oil sealing rolling diaphragm, it is applied to diaphragm type cylinder, including diaphragm
Ontology, the both ends of diaphragm ontology are equipped with opening, and two openings are equipped with the metalwork being used to support.Oil sealing rolling diaphragm exists
It is to roll work between sleeve lining, tray surface in motion process, frictional force is minimum, is equipped with metal in two openings
Part is played a supporting role, and is easily installed, is fixed, is unlikely to deform.
The material of diaphragm ontology is the rubber with nylon fiber cloth interlayer, and metalwork is arranged in rubber.
In some embodiments, diaphragm ontology includes cylindrical section 1, the extension with outward extension of the first end face of cylindrical section 1
The junction of section 2, extended segment 2 and first end face is equipped with changeover portion 3, and the first end face of cylindrical section 1 forms the first opening, cylindrical section
1 second end face is equipped with the second opening.
In the preferred embodiment of the present embodiment, changeover portion 3 is in arc-shaped, avoids after fold when being easily broken off and vulcanizing thanks to glue.
Further, the second opening is equipped with circular protrusion 4, plays sealing effect.
In addition, second end face is equipped with fixation hole.
In some embodiments, when forward direction is installed, there is netted lines in the outer surface of diaphragm ontology, and inner surface is smooth surface, interior table
Face is gas compression face.Leakage can be avoided the occurrence of in this way, improve the compressive resistance of diaphragm.
It should be noted that the device or component of the different function in above-mentioned each embodiment can be combined, for example,
Oil sealing rolling diaphragm in the present embodiment is applied to diaphragm type cylinder, including diaphragm ontology, the both ends of diaphragm ontology are equipped with out
Mouthful, two openings are equipped with the metalwork being used to support.The material of diaphragm ontology is the rubber with nylon fiber cloth interlayer,
