Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Extremely shown in Figure 8 like Fig. 1; The described a kind of pull bar of the utility model; Comprise that an end is provided with the slide bar 2 of joint 1 and the outer tube 4 that an end is provided with fixed base 3, said slide bar 2 passes in outer tube 4 pipes and is provided with, and slide bar 2 and outer tube 4 generally all adopt metallic material to be made.
Be provided with locking structure between said slide bar 2 and the outer tube 4.Particularly; Said locking structure comprises the adjustment fixed cover 5 that is fixed at two ends in outer tube 4 pipes respectively, pipe 7 in being arranged with in outer tube 4 pipes between said two adjustment fixed covers 5, and two ends respectively are provided with a torsion spring 6 in interior pipe 7 pipes; Be provided with switch 8 between two torsion springs 6; Said switch 8 is formed by connecting pressing plate 82 and ring buckle 81, and the both sides, joint of pressing plate 82 and ring buckle 81 respectively form a screens 83, and said slide bar 2 passes adjustment fixed cover 5, torsion spring 6 and ring buckle 81.
Offer a switch on said outer tube 4 tube walls and be provided with mouthfuls 41, laterally offer tube seat 71 on pipe 7 tube walls in said, said pressing plate 82 is provided with mouthfuls 41 through tube seat 71 and switch and stretches out outside the outer tube 4; The width of said tube seat 71 is suitable with pressing plate 82 thickness, and switch is provided with the width of mouth 41 greater than pressing plate 82 thickness.The width of tube seat 71 quite is that pipe 7 rotates with switch 8 in being convenient to pressing plate 82 thickness, and switch is provided with the angle that the width of mouth 41 mainly is limit switch 8 rotations.
Said torsion spring 6 one ends are fixed on the adjustment fixed cover 5, and torsion spring 6 the other ends are arranged in the screens 83.
Said outer tube 4 internal diameters are greater than interior pipe 7 external diameters, and promptly interior pipe 7 can freely rotate in outer tube 4, and the effect of interior pipe 7 mainly is that switch 8 is positioned.
As previously mentioned, adjustment fixed cover 5 is fixed in two ends in the outer tube 4, and preferred said adjustment fixed cover 5 outer walls of the utility model are provided with annular groove 52, and said outer tube 4 inwalls are provided with annular protrusion 42, and said annular protrusion 42 is arranged in the annular groove 52.About the annexation of torsion spring 6 with adjustment fixed cover 5, the utility model preferably laterally is provided with draw-in groove 51 on said adjustment fixed cover 5, and said torsion spring 6 one ends are arranged in the draw-in groove 51.Certainly, the utility model is not got rid of being suitable for of other means of fixation.
