A kind of slide-type self compensation reducing guider
Technical field
The present invention relates to a kind of guider is and in particular to a kind of be applied to the slide-type self compensation detecting tapered pipeline situation
Reducing guider.
Background technology
When detection pipeline internal weld seams, burn into blocking, difference, foreign body, need to put into camera lens inside pipeline
Detected, but different pipe radius are different, and had oil droplet, water droplet, foreign body energy dirt when camera lens enters pipeline
Dye camera lens, leads to detect that inaccurate, conventional guide structure is complicated, inconvenient operation it is impossible to be suitable for the pipeline of different radii,
And endoscope lens are often contaminated, affect Detection results.
Content of the invention
The technical problem to be solved in the present invention is that the guide structure commonly used at present is complicated, and inconvenient operation can be suitable for not
With the pipeline of radius, and endoscope lens are often contaminated, and affect Detection results, provide a kind of structure simple, easy to use, reduce
The slide-type self compensation reducing guider of camera lens pollution.
For achieving the above object, the present invention adopts following technical proposals:A kind of slide-type self compensation reducing guider, including
Slide bar and the sliding sleeve being arranged on slide bar afterbody, sliding sleeve is connected with fix bar, and the head of slide bar is provided with camera lens, is provided with and props up in the middle part of slide bar
Support;Described bracing frame includes fixed cover, slip cap and connecting rod, and connecting rod one end is connected with fixed cover or slip cap, and one
End is connected with skid plate;Described slip cap two ends are provided with fixing spring and counterbalance spring.During use, when pipe radius diminish
When, pipe radius compress skid plate, and the connecting rod hinged with skid plate is drawn close to slide bar, compression compensation spring.
Described skid plate has three, hinged connecting rod on each skid plate.
Described connecting rod is hinged with fixed cover or slip cap.
Described fixing club head is tube-in-tube structure, and in sliding sleeve, the afterbody of sliding sleeve is enclosed within fixing club head to jack rod sleeve
In tube-in-tube structure, sliding sleeve is fixed by fixed screw with the tube-in-tube structure fixing club head.
Present configuration using technique scheme is simple, and easy to use, during work, guider is according to the radius of pipeline
Self adaptation wipes the dirt on pipeline simultaneously, prevents camera lens from polluting, accurate detection effect.
Brief description
Fig. 1 is perspective view of the present invention.
Fig. 2 is main structure diagram of the present invention.
Specific embodiment
As shown in Figure 1 to Figure 2, the present invention includes slide bar 1 and the sliding sleeve 2 being arranged on slide bar 1 afterbody, sliding sleeve 2 and fix bar 5
It is connected, the head of slide bar 1 is provided with camera lens 3, is provided with bracing frame 4 in the middle part of slide bar 1;Described bracing frame 4 includes fixed cover 6, slides
Set 9 and connecting rod 7, connecting rod 7 one end is connected with fixed cover 6 or slip cap 9, and one end is connected with skid plate 8;Described slip cap
9 two ends are provided with fixing spring 10 and counterbalance spring 11.
Described skid plate 8 has three, hinged 3 connecting rods 7 on each skid plate 8, skid plate 8 play support pipeline and
Wipe the effect of pipeline dirt.
Described connecting rod 7 is hinged with fixed cover 6 or slip cap 9.
Described fix bar 5 head is tube-in-tube structure, and slide bar 1 is enclosed within sliding sleeve 2, and the afterbody of sliding sleeve 2 is enclosed within fix bar 5
In the tube-in-tube structure in portion, sliding sleeve 2 is fixing by fixed screw 12 with the tube-in-tube structure of fix bar 5 head.
During use, when pipe radius become hour, pipe radius compress skid plate 8, the connecting rod 7 hinged with skid plate 8 to
Slide bar 1 is drawn close, compression compensation spring 11, and counterbalance spring 11 produces rightabout elastic force, makes the outermost radius of three skid plates 8
Match with pipe radius, reach self-compensating purpose;When pipe radius become big, it is rightabout that counterbalance spring 11 produces
Elastic force makes slip cap 9 to left movement, connecting rod 7 outward expansion, and the outermost radius of final three skid plates 8 are matched with pipe radius
Close, reach self-compensating purpose.When the different pipelines being used in, when pipe radius difference is larger, can be existed by adjusting slide bar 1
The outermost radius of the length in sliding sleeve 2 and then adjustment skid plate 8 are matched with pipe radius, fixing with fixed screw 12.
