Description
Technical field
The utility model belongs to motor device field, specifically a kind of sealing structure for motor waterproof.
Background technique
Application with motor in various fields can encounter the environment of many humidities, this is just needed in its use process
Motor must have certain a waterproof and moisture-proof function, and then realize the sealing of motor and external environment, prevent water and steam into
Enter inside motor, motor is caused to damage.
Currently, waterproof case is arranged usually at the electric motor end cap of motor to carry out waterproof, waterproof cover is directly born against into motor
On the evagination bearing chamber of end cap, to form waterproof construction.Wherein, it is provided with water proof ring in waterproof cover, to improve waterproof performance.
However, in existing waterproof construction, all can not very good solution motor down-lead (connecting line) connect with housing main body caused by
Sealing problem, therefore leverage the waterproof performance of motor.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of motor waterproof sealing structure.
To achieve the above object, the technical solution that the utility model is taken is as follows:
A kind of motor waterproof sealing structure, including housing main body and connecting line, the housing main body are equipped with fairlead, institute
Connecting line is stated to be pierced by from the fairlead；The fairlead is stair-stepping stepped hole, and the diameter holes of the stepped hole are located inside,
Large diameter hole is located at outside, and the inner wall of large diameter hole is equipped with internal screw thread, while sealing ring and bolt are successively arranged in large diameter hole, institute
Stating bolt is interior hollow structure, and its outer wall is equipped with external screw thread, and the connecting line sequentially passes through the diameter holes of stepped hole, sealing
The internal screw thread of circle and bolt hollow portion, the bolt external screw thread and fairlead, which is connected with each other, to be cooperated, and the bolt top after connection
Top tight sealing circle is held, internal diameter of the seal ring reduced outside diameter is expanded.
Further, the sealing ring uses flexible rubber seal.
Further, the bolt uses hollow hex bolts, and hollow hex bolts is plastic parts.
Further, the coupling part of the connecting line and bolt is fixed and is sealed by glue.
Compared with prior art, the utility model has the beneficial effects that this structure solve motor down-lead (connecting line) with
Sealing problem caused by the connection of housing main body；In demand waterproof and moisture-proof field, the sealing of motor and external environment is realized,
It prevents water and steam from entering inside motor by wire connections position, motor is caused to damage.
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of the utility model.
Fig. 2 is hollow hex bolts structural schematic diagram.
Fig. 3 is ring structure schematic diagram.
In the figure, it is marked as 1- housing main body；2- connecting line；3- fairlead；4- sealing ring；5- bolt.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figures 1 to 3, a kind of motor waterproof sealing structure, the structure include housing main body 1 and connecting line 2, the cover
Shell main body 1 is equipped with fairlead 3, and the connecting line 2 is pierced by from the fairlead 3；The fairlead 3 is stair-stepping step
Hole, the diameter holes of the stepped hole are located inside, and large diameter hole is located at outside, and the inner wall of large diameter hole is equipped with internal screw thread, while big
Sealing ring 4 and bolt 5 are successively arranged in diameter hole, the bolt 5 is interior hollow structure, and its outer wall is equipped with external screw thread, described
Connecting line 2 sequentially passes through the diameter holes of stepped hole, sealing ring 4 and bolt hollow portion, 5 external screw thread of bolt and fairlead 3
Internal screw thread is connected with each other cooperation, and the 5 top top tight sealing circle 4 of bolt after connection, expands 4 internal diameter reduced outside diameter of sealing ring
?.
In the utility model, the sealing ring 4 uses flexible rubber seal.The bolt 5 uses hollow six
Corner bolt, and hollow hex bolts is plastic parts.The coupling part of the connecting line 2 and bolt 5 is fixed and close by glue
Envelope.
The utility model expands 4 internal diameter reduced outside diameter of sealing ring by clamping screw 5, compresses seal 4, thus real
Existing sealing function.In addition, increasing for the poor sealing for preventing from dragging connecting line 2 and initiation in the coupling part of bolt 5 and connecting line 2
Add appropriate glue, prevents lead from being slided and being loosened by caused by excessive external force.
The basic principles and main features and advantage of the utility model have been shown and described above.The ordinary skill of this field
Personnel are not it should be appreciated that above-described embodiment limits the protection scope of the utility model, all use equivalent replacements etc. in any form
Mode technical solution obtained, falls in the protection scope of the utility model.
The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
