Embodiment four
The end of button portion 11 is provided with another lock pin 14, and lock pin 14 is buckled in the fast access slot 2a on the concrete blinding 1a.During use; The lock pin 14 of fastener 1 end is sticked in the fast access slot 2a; The fastening angle of rotary buckle 1 adjustment button portion 11 and fixed bar 3a, and then hold pressure handle 211 rotations so that the lock pin 22 of locking bar 21 ends is buckled in the fast access slot 2a on the concrete blinding 1a just.In the present embodiment, only need fastener 1 and latch fitting 2, lock pin 14 and lock pin 22 are buckled in respectively in same the fast access slot 2a, it is very convenient to operate, and can also obtain higher assemble stable property.
Embodiment five
Shown in Figs. 9 to 11, on the holder 12 and vertically pass through hole 121 and be equipped with the bearing pin 15 that freely rotates, bearing pin 15 is provided with screwed hole 16, and latch fitting 2 is located in the screwed hole 16, and locking bar 21 is provided with the external screw thread suitable with screwed hole 16.Bearing pin 15 is used to adjust the angle between locking bar 21 and the button portion 11; The lock pin 14 of button portion 11 is stuck in the fast access slot 2a on the concrete blinding 1a during use; Hold and press latch fitting 2 around bearing pin 15 swings lock pin 22 to be snapped in this fast access slot 2a, the angle between adjustment locking bar 21 and the button portion 11 makes locking bar 21 as far as possible perpendicular to concrete blinding 1a; And make locking bar 21 as far as possible near fixed bar 3a, make locking bar 21 tightly grasp fixed bar 3a with button portion 11; Outwards screw out locking bar 21 then, the lock pin 22 of locking bar 21 ends and the lock pin 14 of buckleing portion 11 ends tightly are buckled in respectively in the fast access slot 2a, thereby fixed bar 3a tightly is pressed against on the concrete blinding 1a.In the present embodiment; Fixed bar 3a for different thicknesses can realize fastening; And concrete blinding 1a, fast access slot 2a, fixed bar 3a etc. exist wearing and tearing and distortion; Perhaps concrete blinding 1a, fast access slot 2a, fixed bar 3a, fastener device etc. locate to exist impurity such as particle, also can concrete blinding 1a and fixed bar 3a be tightened together firmly.Present embodiment operates very convenient, and is not only safe but also reliable after the assembling.
Can both realize that good fixing connects owing to need not precision-fit between each assembly, the securing member, even under the situation such as generation distortion in use, can guarantee that also good fixing connects.Therefore, the present invention is applicable to various complicated construction place, does not receive the restriction of working condition, has the prospect that is suitable for widely.
Embodiment six
Shown in Figure 12 to 19, the main distinction of present embodiment and embodiment five is the assembly relation between locking bar 21, bearing pin 15 and the button portion 11.
The inner hole wall of the screwed hole 16 on the bearing pin 15 outwards is recessed to form recess 161, and locking bar 21 has reducing diameter part 212, and the outer surface of reducing diameter part 212 comprises the light face, and with the suitable flank of screwed hole 16, and this flank and recess 161 corresponding settings.For example, reducing diameter part 212 has two light faces that are oppositely arranged, and two flanks that are oppositely arranged, and then the screwed hole on the bearing pin 15 16 forms two recesses that are oppositely arranged 161.
Locking bar 21 is provided with boss 24 and latch 25; On the locking bar 21 between boss 24 and the latch 25, be arranged with spring 23; The both ends of spring 23 are replaced respectively on the locking bar 21 and on the surface of holder 12; And under the elastic force effect of spring 23, latch 25 is replaced on another surface of holder 12.Can adjust the advance and retreat amount in the bearing pin 15 of locking bar 21 on holder 12 through spring 23 and latch 25, improve the convenience of operation.
Preferably; The lock pin 22 of locking bar 21 ends is parallel in same plane with pressure handle 211, the bearing of trend of corresponding lock pin 22 of the light face of reducing diameter part 212 and pressure handle 211, like this; Be convenient to hold pressure handle 211 and locking bar 21 compressed into and withdrawed from the screwed hole 16 on the bearing pin 15 fast, improve the operability of latch fitting 2.
During installation, button portion 1 is fastened on the fixed bar 3a, holds pressure handle 211, makes the corresponding recess 161 of flank on the reducing diameter part 212, pushes pressure handle 211, and the lock pin 22 of locking bar 21 ends is sticked in the fast access slot 2a on the concrete blinding 1a; Then, rotation pressure handle 211 is screwed flank and the screwed hole 16 on the bearing pin 15 on the reducing diameter part 212, through fastener device concrete blinding 1a is fastened on the fixed bar 3a like this.
During dismounting; Push in lock pin 22 that pressure handle 211 and rotation the make locking bar 21 ends fast access slot 2a from the concrete blinding 1a; Screwed hole 16 on flank and the bearing pin 15 on the reducing diameter part 212 is thrown off to be connected; And make the flank on the reducing diameter part 212 go to recess 161 places, under the elastic force effect of spring 23, locking bar 21 resets fast.
In the present embodiment, when the corresponding recess 161 of the flank on the reducing diameter part 212, the sectional dimension of reducing diameter part 212 is less than the aperture of screwed hole 16, locking bar 21 can be in screwed hole 16 fast advance and retreat, and needn't rotate and could advance and retreat; Only need rotate the flank that makes on the reducing diameter part 212 and screwed hole 16 in the time of need screwing togather is screwed and gets final product.
The foregoing description and accompanying drawing and non-limiting product form of the present invention and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from patent category of the present invention to its suitable variation or modification of doing.
