Abstract
The utility model provides a conical sealing ring. The outer contour of the conical sealing ring is conical, the inner contour thereof is in the shape of a hollow cylinder, and a conical angle of a conical surface of the outer contour ranges from 50 degrees to 70 degrees. The conical sealing ring has the advantages that the sealing ring adopting the structure is large in sealing area as the contacting position of the sealing ring and a to-be-sealed object is a cylindrical surface, fine in property and long in service life, can optionally adjust sealing force determined by tightness of a hollow hold-down bolt, can be used for sealing non-rigid components such as electric wires and cables, and can be used for sealing rigid components such as pipelines.
Description
Technical field
The utility model belongs to static seals, especially for the cable conical seal ring of band rubber or plastic sheath.
Background technique
When the instrument and apparatus box has cable outwards to draw internally, need carry out the water proof and dust proof sealing to cable and instrument and apparatus box junction point.General sealing means is to seal with round section joint ring at present.Because " O " shape seal ring and sealed device contacts area are little, the elastic deformation amount is little, and the sealing rigid device is all right, when being non-rigid device such as rubber plastic for sealed, as cable etc.Because the contacting point is the line contact, area of contact is little, and pressure is easy to greatly be become groove by round section joint ring compressive strain, and the time one is long, and sealed produces permanent deformation, lose sealing effect.
Summary of the invention
The utility model purpose is to provide a kind of conical seal ring, and the cable of drawing of instrument and apparatus box is carried out water proof and dust proof sealing.
For achieving the above object, the technical solution adopted in the utility model provides a kind of conical seal ring, and wherein: the external frame of this conical seal ring is conical, and interior profile is the hollow cylinder shape.The cone angle of the conical surface of described external frame is 50 °-70 °.
It is barrel surface that effect of the present utility model is to use the seal ring of this structure to make seal ring and sealed 's contacting point, thereby sealing area is big.The degree of tightening of hollow housing screw has determined the size of sealing force, and sealing force can be adjusted arbitrarily.Be used for non-rigid portion, as the sealing of electric wire cable, performance is good, the life-span is long, also can be used for rigid element, as the sealing of pipeline.

Fig. 3 is conical seal ring force analysis figure of the present utility model.
Among the figure:
1, conical seal ring 2, hollow hold-down bolt 3, draw cable 4, instrument and apparatus box
Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated cone seal coil structures of the present utility model.
Cone seal coil structures of the present utility model is: the external frame of this conical seal ring is for conical, and interior profile is the hollow cylinder shape.The cone angle of the conical surface of described external frame is 50 °-70 °.
As shown in Figure 1, the gabarit of conical seal ring 1 is shaped as a cone, and cone angle commonly used is 60 °, and interior profile is the hollow cylinder shape, and promptly interior exterior feature is a cylindrical bore.Its diameter of bore and length dimension be along with the size of sealed external diameter, proportional increase or dwindle.Its serial size sees the following form.
The male cone (strobilus masculinus) of conical seal ring 1 matches with the inner conical surface of instrument and apparatus box 4.Conical seal ring compresses the large end face of conical seal ring 1 by hollow hold-down bolt 2, and impacting force is adjustable.
The dimension series table
As shown in Figure 2, draw cable 3 during installation and pass the center hole of conical seal ring 1 earlier, small end by conical seal ring 1 enters, the big end of conical seal ring 1 passes, pass the center hole of hollow hold-down bolt 2 again, the male cone (strobilus masculinus) of conical seal ring 1 is placed on the inner conical surface of wire outlet of instrument and apparatus box 4, with the screw thread of hollow hold-down bolt 2, tighten hollow housing screw 2 then by instrument and apparatus box 4.
As shown in Figure 3, when conical seal ring is installed,, be 60 ° of calculating by conical seal ring 1 cone angle commonly used because hollow hold-down bolt 2 is given axial pressure P of large end face of conical seal ring 1, then produce 2 pressure F of symmetry on conical surface, its direction is perpendicular to the bus of conical surface.More than three power place state of equilibrium, and the big or small F=P of power.
Because power F is perpendicular to the bus of conical surface, it can be decomposed into two power F1 and F2 again, and F1 and axial direction are put down to, big or small F1=FSin30 °=0.5F of power, and power F1 and pressure P balance each other; F2 is vertical with axial direction, and big or small F2=FCOS30 °=0.866F of power, power F2 promptly are the power that imposes on conical seal ring 1.By the distortion of rubber material, between conical seal ring 1 and sealed, also produce onesize sealing force.This shows that all pressure that imposes on a unit on conical seal ring 1 end face will produce two 0.866 unit sealing forces, that is to say the size of sealing force, can regulate by the degree of tightening of hollow hold-down bolt 2, it is tight more that hollow hold-down bolt 2 is twisted, and then sealing force is just big more.
Can change the size of cone seal loop diameter, cone angle as required, its cone angle is more little, and the ratio of sealing force and impressed pressure is big more.Be mainly used in the sealing to the cable oversheath when having cable to draw of instrument and apparatus box, also can be used for the sealing of cylindrical hard parts.Because the large end face of seal ring is subjected to an installing force, produce a pressure in the use, rely on this pressure to reach the purpose of sealing to central direction at conical surface place.
