Specific embodiment
Present embodiment provides a kind of cable sealing structure, and the sealing of connector is realized in compact space,
With dustproof and waterproof function.The utility model additionally provides a kind of linear actuator with above-mentioned cable sealing structure.
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.
Please refer to Fig. 1-2, a kind of cable sealing structure provided in this embodiment, including for fill driver cable 3 with
The sealing ring 2 in gap between the cable entries of drive enclosure 1.
In the application, there is gap, in order to reach between the cable entries hole and driver cable 3 of drive enclosure 1
The purpose of dustproof and waterproof expires the setting of sealing ring 2 within the cleft and by the gap filling, and the inside and outside realization of drive enclosure 1 is close
Envelope.The cable sealing structure, structure is simple, is provided only in interstitial site, and the sealing of connector is realized in compact space,
With dustproof and waterproof function.
In further embodiment, sealing ring 2 has ring inner hole 7, and driver cable 3 passes through sealing ring 2
Ring inner hole 7.It is provided with o-ring groove 6 on the outer wall of sealing ring 2 and the cable entries relative position of drive enclosure 1,
O-ring groove 6 is used to be clamped with the cable entries wall surface of drive enclosure 1.Sealing ring 2 is distinguished in the two sides of o-ring groove 6
Equipped with sealing ring outer lug boss 4 and sealing ring inner convex platform 5, it is fixed for the axial direction to driver cable 3.
The width of o-ring groove 6, i.e. 5 spacing of sealing ring outer lug boss 4 and sealing ring inner convex platform, with drive enclosure 1
The wall thickness of cable entries wall surface is close, so that sealing ring is radially fixed after realizing assembly.Preferably, the width of o-ring groove 6
Degree is less than or equal to the wall thickness of the cable entries wall surface of drive enclosure 1, in particular, driving when the width of o-ring groove 6 is less than
When the wall thickness of the cable entries wall surface of dynamic device shell 1, o-ring groove 6 and the cable entries wall surface interference of drive enclosure 1 are matched
It closes, further fastens the two.
It should be noted that defining " width " according to following principle herein, i.e., the left and right of Fig. 1 is width as described herein
Degree.Above-mentioned definition merely for convenience of description, can not limit the protection scope of this programme.
In further embodiment, the outer diameter of sealing ring outer lug boss 4 is less than the outer diameter of sealing ring inner convex platform 5.Sealing
It is larger to enclose 5 outer diameter of inner convex platform, when assembly is oriented internal drive, this design can effectively prevent sealing ring 2 to be drawn out driver
Shell 1.4 outer diameter of sealing ring outer lug boss is smaller, and when assembly is oriented outside driver, need to can be by sealing ring from drive when assembly
Dynamic device shell from inside to outside release and block to the cable inlet of drive enclosure 1 by side.
Further, fillet is arranged in sealing ring outer lug boss 4 and/or the part outer rim of driver inner convex platform 5, particularly, close
Fillet at seal outer lug boss 4 can reduce the resistance of sealing ring pushing out card to 1 cable entries of drive enclosure, be conducive to seal
Circle is smoothly pushed out on the outside of drive enclosure in 4 one end of sealing ring outer lug boss.
Further, the width of sealing ring inner convex platform 5 in the axial direction is greater than the width of sealing ring outer lug boss 4 in the axial direction.
Larger width is arranged in the width of sealing ring inner convex platform 5, it is therefore an objective to when cable is pullled by external force, have biggish resistance, prevent
Sealing ring is drawn out.
In order to reinforce sealing effect, sealing ring 2 is greater than or equal to the line of drive enclosure 1 in the outer diameter of o-ring groove 6
The outer diameter of cable inlet, using interference connection type, so that between sealing ring 2 and drive enclosure 1 and driver cable 3 more
It fits closely.
Similarly, 7 diameter of ring inner hole is less than or equal to 3 diameter of driver cable.It is less than in 7 diameter of ring inner hole and drives
When dynamic 3 diameter of device cable, sealing effect is more preferable.
Particularly, sealing ring 2 is rubber seal, and asbestos board or elastomer material also can be used in sealing ring 2.
To sum up, after driver cable 3 is inserted into sealing ring 2, sealing ring 2 is squeezed deformation, realizes sealing effect.This programme
A kind of new cable seal mode and sealing structure are realized, realizes target seal, cable sealing structure with least components
It is compact, it occupies little space, and dismount simply, is easily changed and safeguards.
In addition, the present embodiment additionally provides a kind of linear actuator, including cable sealing structure, and the cable seal knot
Structure is the cable sealing structure as disclosed in above-described embodiment, and therefore, the linear actuator with the cable sealing structure also has
There are above-mentioned all technical effects, this is no longer going to repeat them.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with features of novelty.
