As long as all being protected by Patent Law in right of the present utility model.
Embodiment, telescopic measurement bar, as shown in figure 1, including columnar mother set bar 11, the upper end of mother set bar 11 is provided with
Circular opening, the lower end closure of mother set bar 11.The opening of the top of mother set bar 11 is inserted with sub-set bar 12, the structure of sub-set bar 12
It is identical with the structure of mother set bar 11, and the quantity of sub-set bar 12 has three, three sub- loop bars 12 are arranged form successively, sub-set bar 12
On be carved with reference mark 13；Sub-set bar 12 will be bounced back to successively in mother set bar 11 after compressing；And measurement bar is when in use, by sub-set
Bar 12 goes out from pull in mother set bar 11 so that measurement bar whole length increased.Also labelling quarter is carved with mother set bar 11
Degree 13.
As shown in Fig. 2 mother set bar 11 offers longitudinal deep gouge 21, the cross section of deep gouge 21 is circular arc, reference mark
13 bottom lands for being placed in deep gouge 21, and the arc-shaped cavity 22 that a section is circular arc is offered on the side wall in the left side of deep gouge 21.Arc
Chamber 22 is interconnected with deep gouge 21 and both bending radius are identical.
As shown in figure 3, the section of curved cover plate 3 is arc-shaped, and the bending of the bending radius of curved cover plate 3 and arc-shaped cavity 22
Radius is identical, and curved cover plate 3 inserts arc-shaped cavity 22 in the way of the cooperation of gap, and curved cover plate 3 can be carried out in arc-shaped cavity 22
The sliding of circumferencial direction.The appearance of curved cover plate 3 is offered stirs breach 33, and it is rectangular-shaped and to curved cover plate to stir breach 33
3 inner wall depressions, after curved cover plate 3 skids off arc-shaped cavity 22, curved cover plate 3 covers the notch of deep gouge 21, and now, if by arc
Shape cover plate 3 is reversed in arc-shaped cavity 22, and user is quick by curved cover plate to reach by the way that finger force is being stirred into breach 33
3 slip in arc-shaped cavity 22.
The structure of the upper and lower ends of arc-shaped cavity 22 is identical, is to offer chute 51, and chute 51 sets along the extension of circular arc direction
Put, two side walls of chute 51 are corrugated curved surface, and notch and the accent of arc-shaped cavity 22 of chute 51 are interconnected.Arc covers
Plate 3 will be by skidding off in arc-shaped cavity 22, and then sliding is continued in the two of curved cover plate 3 end 52 along chute 51, camber line cover plate
The outer wall of end 52 is also waveform, curved cover plate 3 and the mutual sliding in the way of the cooperation of gap of chute 51, curved cover plate 3 and cunning
Frictional force between groove 51 has the effect of fixed curved cover plate 3.Vertical plane between two ends 52 of curved cover plate 3 is side
Edge 43.
As shown in figure 4, side is slided along 43 towards groove 41, the rectangular cross-section of groove 41, and groove 41 be along
What the longitudinal direction of mother set bar 11 opened up, the bottom land of groove 41 is bonded with sealing strip 42 made by rubber, the edge of curved cover plate 3 by glue
Circumferencial direction sliding and its side will slide in groove 41 along 43, the side of curved cover plate 3 will be contradicted in sealing along 43
On bar 42.
Compression spring 6 is provided with inside arc-shaped cavity 22, one end of compression spring 6 is welded in the cavity wall of arc-shaped cavity 22, is compressed
The other end of spring 6 is contradicted on curved cover plate 3.Compression spring 6 is in compressive state, therefore it will produce an elastic force, the bullet
Power will promote curved cover plate 3 release arc-shaped cavity 22 and cause curved cover plate 3 closes arc-shaped cavity 22 so that formed one isolate
Chamber.And curved cover plate 3 is that by made by transparent plastic, when curved cover plate 3 is covered in arc-shaped cavity 22, user still can be straight
Connect curved cover plate 3 and observe reference mark 13.Locking mechanism is additionally provided with curved cover plate 3.
