Abstract
The utility model discloses a kind of axis hole installation sealing structures, including rubber sealing structure (3), there is mounting hole in rubber sealing structure (3) center, transitional connection pipe (22) are equipped in the mounting hole of rubber sealing structure (3), transitional connection pipe (22) upper end diameter is less than lower end diameter, lower end surface is connected with the inner wall of mounting hole, has gap between upper surface and the inner wall of mounting hole.After the utility model installation, sealing element conical pipe middle and lower part deforms fitted shaft, and conical pipe superstructure still packs tightly sealing, in addition the effect of lip reinforcement structure, sealing effect are unaffected.
Description
Technical field
The utility model relates to a kind of rubber seal rings for sealing.
Background technique
At this stage, because of the requirement of use environment, the electronic system of the products such as some automobiles, engineering machinery is used with coding
The isometric place of code switch, grip of the products such as switch, grip needs sealing protection.It is by circular shaft structure four that it, which is sealed,
It is all uniformly to compress rubber sealing structure sealing, structure as shown in Figure 1, be set with the sealing element that a rubber is done on axis, sealing element
The fitting of the outside wall surface of inner wall of the hole installing face 5 and axis 2.Another structure such as Fig. 2 has protrusion on the inner wall 5 of rubber seal
Sealing ring.
The mounting design of both sealing structures has following disadvantage:
1. installation sealing is more demanding to axis and the center of circle (axle center) concentricity in rubber sealing structure hole, once axis and rubber
Sealing structure hole center of circle concentricity is poor (when the axis 1 of axis 2 and the mounting hole axis 11 of rubber sealing structure 3 be not coaxial, to see figure
3 and Fig. 4) when, side forced compression and the other side form gap 12, and sealing effect is bad, and coaxiality deviation is bigger, sealing effect
It is poorer, or even failure；
2. the design of sealing structure, sealing hole is less than shaft diameter, is not easy to the installation of axis, especially axis and rubber seal knot
When the concentricity difference in structure hole is larger；
3. requiring sealing effect good, need axis big to the decrement of rubber sealing structure, in this way, being not easy to axis when assembly
Installation, especially axle center and when hole heart deviation is larger or shaft diameter is larger.
Summary of the invention
The technical problems to be solved in the utility model: required precision ratio is cooperated to axis for existing gland seal structure
Higher problem provides a kind of structure that can effectively seal axis is not overlapped.
The technical solution of the utility model includes:
There is mounting hole in a kind of axis hole installation sealing structure, including rubber sealing structure, rubber sealing structure center, and rubber is close
Transitional connection pipe is equipped in the mounting hole of seal structure, transitional connection pipe upper end diameter is less than lower end diameter, lower end surface and mounting hole
Inner wall connection, have gap between upper surface and the inner wall of mounting hole.
There is lip configuration in transitional connection pipe upper surface.
Transitional connection pipe upper semisection wall surface is cylindrical surface, and lower semisection wall surface is curved surface.
Rubber sealing structure is embedded on product casing, and transitional connection pipe upper semisection covers on axis.
The utility model the utility model has the advantages that
When axle construction and not coaxial sealing element mounting hole, after installation, sealing element conical pipe middle and lower part deforms fitted shaft, cone
Shape pipe superstructure still packs tightly sealing, in addition the effect of lip reinforcement structure, sealing effect are unaffected.With following several
Point advantage:
(1) this structure requires the mounting hole hole heart concentricity of axis and sealing element low, when concentricity has certain deviation, taper
Still good seal, the concentricity cooperation for reducing structure require pipe structure, improve sealing effect；
(2) design of tapered tube configuration is installed convenient for the guiding of axis；
(3) installation sealing structure of tapered tube configuration is small and easily-deformable, hinders power smaller the insertion installation of axis, convenient for peace
Dress.

Fig. 1 is the schematic diagram of existing sealing structure one.
Fig. 2 is the schematic diagram of existing sealing structure two.
Fig. 3 is the seal failure schematic diagram of existing sealing structure one.
Fig. 4 is the seal failure schematic diagram of existing sealing structure two.
Fig. 5 is the utility model structure diagram.
Fig. 6 is distressed structure schematic diagram of the utility model when deviation occurs in concentricity.
Specific embodiment:
Embodiment 1:
Rubber sealing structure 3 is embedded in the axis hole of product casing 4, and 3 center of rubber sealing structure is mounting hole, mounting hole
In be equipped with transitional connection pipe 22, the upper semisection wall surface of transitional connection pipe 22 is cylindrical surface, and lower semisection wall surface is the curved surface of cone,
22 lower end surface of transitional connection pipe is connected with the inner wall of the central mounting hole of rubber sealing structure 3, the inner wall of upper end and mounting hole
Between formed 2-5mm gap.22 wall thickness of tapering transition connecting tube is 0.5mm, and axis 2 is sleeved on the upper semisection of transitional connection pipe 22
In, the small 0.5mm of outer diameter of the interior diameter ratio shaft 2 of 22 cylindrical surface of connecting tube section.When the installation of the axis 1 and rubber sealing structure 3 of axis 2
When axially bored line 11 is not overlapped, the upper semisection of transitional connection pipe 22 will not be deformed, and lower semisection side is compressed, and the other side is drawn
It stretches.
Embodiment 2:
Rubber sealing structure 3 is embedded in the axis hole of product casing 4, and 3 center of rubber sealing structure is mounting hole, mounting hole
In be equipped with transitional connection pipe 22, the upper semisection wall surface of transitional connection pipe 22 is cylindrical surface, and lower semisection wall surface is the curved surface of cone,
It is parabolic surface in the present embodiment, 22 lower end surface of transitional connection pipe is connected with the inner wall of the central mounting hole of rubber sealing structure 3,
There is lip configuration 21 on upper surface, forms the gap of 10-30mm between lip configuration 21 and the inner wall of mounting hole.Tapering transition
22 wall thickness of connecting tube is 5mm, and axis 2 is sleeved in the upper semisection of transitional connection pipe 22, the interior diameter ratio shaft 2 of 22 cylindrical surface of connecting tube section
The small 5mm of outer diameter.When the mounting hole axis 11 of the axis 1 of axis 2 and rubber sealing structure 3 is not overlapped, transitional connection pipe 22
Upper semisection will not deform, and lower semisection side is compressed, and the other side is stretched.
