Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the A-A sectional view in Fig. 2.
Fig. 4 is that the B in Fig. 3 is to local expansion view.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: scalable traction latch 3 assembly in embodiment is mainly made up of sleeve 1, end cap 2, latch 3, handle 4, spring 5, guide finger 6 and screw 7.
As shown in Figure 1 and Figure 2, end cap 2 is installed in described sleeve 1 upper end, and end cap 2 center is provided with through hole, described latch 3 is contained in sleeve 1, latch 3 upper end passes and mounting knob 4 from end cap 2 central through hole, and latch 3 lower end passes from sleeve 1 bottom center hole, and latch 3 can be free to move axially in sleeve 1；Described spring 5 is sleeved on latch 3 and is placed in sleeve 1, and spring 5 upper end is connected with latch 3, and spring 5 lower end withstands on sleeve 1 base plate；Described sleeve 1 wall is provided with vertical gathering sill section 1a.1 and horizontal draw-in groove section 1a.2 that L-shaped notch 1a, described L-shaped notch 1a include being interconnected, and described latch 3 is provided with a perpendicular guide finger 6, and the activity of described guide finger 6 is placed in described L-shaped notch 1a.
As shown in Figure 1 and Figure 2, in the present embodiment, described latch 3 is provided with step 3a, and described spring 5 upper end withstands on step 3a, is achieved in the connection of spring 5 and latch 3.
As shown in Figure 1 and Figure 2, in the present embodiment, the end of described horizontal draw-in groove section 1a.2 is provided with the limited mouth 1a.3 upwards caved in, and so can be stuck in limited mouth 1a.3 when latch 3 enters into horizontal draw-in groove section 1a.2, safer reliably.
As shown in Figure 1 and Figure 2, in the present embodiment, described handle 4 screw 7 is fastened on latch 3, and handle 4 is provided with anti-slip veins.
When specifically applying, grasping handle 4 to press down on, the guide finger 6 on latch 3 moves downward, when moving to minimum point along vertical gathering sill section 1a.1 of L-shaped notch 1a, rotate latch 3, in making guide finger 6 enter into horizontal draw-in groove section 1a.2 of L-shaped notch 1a and snap in limited mouth 1a.3.
When needs release and connect, grasp handle 4 to press down on, guide finger 6 is made to depart from the limited mouth 1a.3 of horizontal draw-in groove section 1a.2, rotate latch 3, guide finger 6 is made to enter vertical gathering sill section 1a.1 from horizontal draw-in groove section 1a.2, loosing one's grip, under spring 5 acts on, latch 3 can automatically reset, and end cap 2 plays the position-limiting action after latch 3 resets.
