Specific embodiment

Embodiments of the present invention is further illustrated below in conjunction with the accompanying drawings：Orientation up and down as described herein is with shown in FIG. 1 Subject to upper and lower orientation.

In the embodiment of the present invention, a kind of key chain, including housing 1, hanging buckle 2, pendant 3, the housing 1 is equipped with push button 4, 4 bottom of push button is equipped with sliding block 5, and the sliding block 5 is placed in the housing 1, the push button 4 at the housing 1 on glide It moves, the hanging buckle 2 includes fixed arm 6 and lever arm 7, and the fixed arm 6 is integrally formed with the housing 1, is set in the housing 1 There is articulated shaft 12, the lever arm 7 is hinged with the articulated shaft 12, and the lever arm 7 includes closed end 8 and driving end 9, described Sliding block 5, which has, pushes the driving end 9 to make first state of the closed end 8 far from fixed arm 6, the driving end 9 is pushed to make closed end 8 Close to fixed arm 6 the second state and withstand it is described driving end 9 make what the closed end 8 was bonded and locked with the fixed arm 6 The third state.

The driving end 9 is " J " type, there is preceding pushing part 10 and rear pushing part 11, and the preceding pushing part 10 is long one end, Pushing part 11 is circle hook portion after described, and the rear pushing part 11 is in said first condition in 5 rear end of sliding block, in institute It states and 5 side wall of sliding block is withstood under the third state.

Need to take containing key when, as long as pushing up push button, preceding pushing part makes the lever arm described in slipper push It is rotated around the articulated shaft far from the fixed arm, the rear pushing part goes to the sliding block rear, and hanging buckle is opened, you can is taken Containing key, as long as decontroling push button later, push button and lever arm can automatically reset and lock, and operation is very easy.

The lever arm 7 is equipped with articulated section 13, and the articulated section 13 is sleeved on the articulated shaft 12,13 side of articulated section Face is equipped with storage tank 14, and the articulated shaft 12 runs through the storage tank 14, and being equipped in the storage tank 14 makes the lever arm 7 multiple First torsional spring of position, the first one end are placed in storage tank 14, and the other end is stuck at the block 23 in housing, and sliding block 5 is in During the first state, lever arm 7 is rotated around articulated shaft 12, and the deformation of the first torsional spring generates inside elastic force, makes lever arm 7 in cunning Block 5 automatically resets after resetting.

Pillar 20 is equipped in housing 1, the pillar 20 is equipped with the second torsional spring, and second one end is placed in the cunning On block 5, have on the sliding block 5 and limit the cylinder 21 of cooperation with it, the other end and the inner walls of second torsional spring connect It touches, when pushing up push button, the second torsional spring provides a downward elastic force, and push button 4 is made to automatically reset after hand relieving.

1 surface of housing is equipped with guide-track groove 15, and card slot 16 and guide-track groove are equipped between the sliding block 5 and the push button 4 15 adaptations, 15 one end of guide-track groove is wider, is adapted to the size of sliding block 5, when key chain assembles, facilitates sliding block being placed in housing Interior, the other end is relatively narrow, and the sliding block in this relatively narrow side slip of push button 4 does not fall out housing, and limited post is equipped in the housing 1 19, after the completion of key chain assembling, limited post 19 is placed in the wider position of guide-track groove 15, and anti-limited slip block drops out from installation opening.

The push button bottom is equipped with guide groove 22, and 1 surface of housing is equipped with convex with the guide groove 22 limiting cooperation 17 are played, the two limiting cooperation makes push button will not be unsceptered in sliding.

The guide-track groove both sides are equipped with sliding rail 18, and the push button 4 is contacted with the sliding rail 18, reduce frictional force, use hand Sense is more comfortable.
