Abstract
The utility model relates to attributed to survey technology, a member to clip tape band to overcome the easy deformation of the band sliding slice 4 of existing tape, failure of tight clipping of tape band. The clip for tape ban comprises a tape shell 1, a sliding key on the tape shell 1; a sliding key 2 is provided with a sliding slice 4 in a sliding groove 3 within the tape shell 1, a rotary block 6 which can be clipped at a tape ban 5 is arranged at the tape shell 1; the sliding slice 4 and theblock 6 are hinged for coupling. Due to the stiffness of the block, loose clip from elastic deformation of sliding clip on the tape ban is avoided when the block is clamped at the tape ban by rotation, the tape band clipping is more reliable without damage to the surface of tape bend for sake of loose of clipping of tape band.
Description
Technical field
The utility model belongs to field of measuring technique, is a kind of band tape clamping body.
Background technology
Existing tape measure structure comprises Flexible rule case 1 as shown in fig. 1, is arranged on the slide key 2 on the Flexible rule case 1, and described slide key 2 is provided with the slide 4 that is stuck in Flexible rule case 1 sliding tray 3, is provided with the rich chi band 5 of volume in described Flexible rule case 1.During use, when chi band 5 pulls out from Flexible rule case 1, promoting slide key 2 moves to chi band 5 directions, the front end of slide 4 will withstand on the chi band 5, and chi band 5 is squeezed on the edge wall of Flexible rule case 1 and clamps, the part that makes chi band 5 be drawn out Flexible rule case 1 keeps stretching out at Flexible rule case 1 outside motionless, is used for measuring.Its shortcoming is owing to Flexible rule case 1 outer edge part is arranged to arc structure for the shape that adapts to the chi tape wrapping often, cause slide key 2 to promote slide 4 and do circular motion, chi band 5 is pulled out the back fixedly the time when needs like this, the direction of slide key 2 to chi band 5 pushed away, the end of slide 4 will withstand on the chi band 5 according to arc track, and become an oblique angle between slide 4 and the chi band 5 this moment.Because slide 4 is oblique withstands on the chi band 5, if slide key 2 is pressed downwards, slide 4 is bending again, and the slit between chi band 5 and Flexible rule case 1 edge is involved in, and just can't make the chi strap clamp tight this moment.Become an oblique angle to be pressed on the chi band 5 based between slide 4 and the chi band 5, when chi band 5 is touched in the outer end or twitches, make the opposite direction motion of slide 4 easily, cause getting loose between slide 4 and the chi band 55 backrush of chi band to chucking.So in existing tape measure structure, slide 4 slides excessive to chi band direction, be easy to generate distortion, on the contrary can not the chi strap clamp is tight, get loose easily.Slide 4 slides not in place to chi band direction, nature can't be tight with the chi strap clamp.In case user's finger leaves slide key 2, chi band 5 is being subjected to the push-and-pull action of external force, is easy to make slide key 2 to slide to the direction away from chi band 5, causes getting loose between slide 4 and the chi band 5, so chi band chucking is unreliable.
The utility model content
The purpose of this utility model is to provide a kind of chi band chucking reliable, the band tape clamping body that the chi band is difficult for being worn.
For realizing the purpose of this utility model, described band tape clamping body comprises Flexible rule case, be arranged on the slide key on the Flexible rule case, described slide key is provided with the slide that is stuck in the Flexible rule case sliding tray, being provided with the rotatable fixture block that is stuck on the chi band on the described Flexible rule case, hinged between described slide and the fixture block.
Because Flexible rule case is provided with the rotatable fixture block that is stuck on the chi band, fixture block rotates to a direction, it is contacted with the chi band be clamped on the Flexible rule case edge, then allows fixture block to counter-rotation, and it is separated with the chi band, makes tape measure be in nature and reclaims state.Since hinged between slide and the fixture block, promote slide and can make it drive the fixture block rotation.Fixture block distance between the chi band is very near, when fixture block is stuck on the chi band by rotation, because fixture block has favorable rigidity, avoided above-mentioned prior art to cause clamping not strongly solid defective because of the elastic deformation that slide is held on the chi band, make chi band chucking reliable, with the wearing and tearing of having avoided tightly not causing tape band surface because of chi band card.
Description of drawings
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural drawing of prior art tape measure.
Fig. 2 is the three-dimensional wiring layout of the utility model band tape clamping body.
Fig. 3 unclamps the structural drawing of chi band for the utility model band tape clamping body.
Fig. 4 is the structural drawing of the utility model band tape clamping body chucking chi band.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model band tape clamping body is described in further detail:
As shown in Fig. 2,3, the utility model band tape clamping body comprises Flexible rule case 1, slide key 2, sliding tray 3, slide 4, chi band 5, fixture block 6, neck 7, end axle 8, annulate shaft arm 9, axis hole 10, rotating shaft 11, half shells 12, breach 13, card division 14, breach 15.
Described Flexible rule case 1 comprises two and half shells 12, and the edge that is provided with breach 13, half shells 12 of ccontaining slide key 2 on half shell is provided with the arc sliding tray 3 of placing slide 4.After two and half shells 12 merged, slide key 2 was in the breach 13, and slide 4 is then in sliding tray 3.Promoting slide key 2 can make slide 4 slide at sliding tray 3 arcs.
Described slide 4 ends are provided with the neck 7 that extends to fixture block 6, and described neck 7 is provided with the end axle 8 that stretches to both sides, and described fixture block 6 is provided with the annulate shaft arm 9 that extends to end axle 8.Described annulate shaft arm 9 is to extend to chi band 5 direction of recession from axis hole 10.When slide 4 during to lower slider, the end axle 8 on the slide 4 can promote the annulate shaft arm 9 below the fixture block 6, and fixture block 6 is clockwise rotated, and is stuck in chi band 5.When slide 4 upwards slided, the end axle 8 on the slide 4 can drive the annulate shaft arm 9 above the fixture block 6, and fixture block 6 inhours are rotated, and left chi band 5, and chi band 5 can be bounced back.
Described fixture block 6 is provided with axis hole 10, and Flexible rule case 1 is provided with the rotating shaft 11 that is inserted in the axis hole 10.Rotating shaft 11 is arranged on half shell 12, and when two and half shells 12 lumped together, 11 of the rotating shafts on two and half shells 12 were deep in the axis hole 10 simultaneously, makes fixture block 6 be positioned on the Flexible rule case 1 and 11 rotations around the shaft.
Described fixture block 6 is provided with the card division 14 that extends to chi band 5.When fixture block 6 is in when blocking chi band 5 positions, card division 14 is perpendicular to chi band 5, this moment 14 pairs of chi band 5 surfaces, card division the friction force maximum, and card division 14 is very short, is difficult for producing distortion, and is the tightst to holding of chi band 5, holds firmly.Even slide 4 continues down motion, card division 14 clockwise rotates a bit continuing, in case loose one's grip, will drive card division 14 inhours and rotate in the process that chi band 5 is reclaiming, friction force between this moment card division 14 and the chi band 5 will become greatly gradually, and prevention makes chi band 5 stuck and can't bounce back.
Be provided with breach 15 in the middle of the card division 14, prevent the scale numeral in the 14 wearing and tearing chi bands 5 of card division.
