Waist-shaped hole 31, it is additionally provided with for hindering the first bearing pin 5 to the elastic parts 6 for buckling 1 movement on locking closure 3.
Hasp lock of the present utility model, with the junction of the first bearing pin 5 it is waist-shaped hole 31 on its locking closure 3 so that the first bearing pin 5
Certain distance can be moved back and forth along waist-shaped hole 31, set elastic parts 6 to be used for hindering the first bearing pin 5 to buckling 1 shifting on locking closure 3
It is dynamic, due to the second bearing pin 200 button located at buckle on 1 when, what the position of the first bearing pin 5 was to determine, namely during locking connecting rod 4 for
The pulling force of first bearing pin 5（Or coupling mechanism force）By the elastic effect of elastic parts 6, and case lid is respectively to take for the pressure of casing
Pulling force of the connecting rod 4 of padlock for the second bearing pin 200（Reaction force of the connecting rod 4 for the pulling force of the first bearing pin 5）Sum, pass through
The elastic force of regulation elasticity component 6, the regulation of coupling mechanism force can be realized, case lid is in suitable scope for the pressure of casing,
Ensure sealing effectiveness.
In the present embodiment, elastic parts 6 includes spring 61, guide rod 62 and the keeper 63 being fixedly arranged on locking closure 3, leads
Actively it is arranged in keeper 63 to the one end of bar 62, the other end offsets with the first bearing pin 5, and spring 61 is sheathed on guide rod 62
On.When needing locking, the elastic force of elastic component 100 is overcome to act on upset locking closure 3, locking closure 3 drives the first bearing pin 5 to move,
First bearing pin 5 drives guide rod 62 to buckling 1 movement, the compression spring 61 of the first bearing pin 5 in motion process（Namely in the present embodiment
Spring 61 is compression spring）, spring 61 applies reaction force to the first bearing pin 5, and then can be by adjusting the elastic force of spring 61
To adjust pulling force of first bearing pin 5 for connecting rod 4.The adjustment of the elastic force of spring 61 can be by changing specification or the compression of spring 61
Deflection is realized.Realized in the present embodiment using the compress variation of regulation spring 61.Specifically：
Elastic parts 6 also includes adjusting set 64, and adjusting set 64 coordinates with the screw thread of guide rod 62, and adjusting set 64 and locking closure 3 are tight
Patch, spring 61, which supports, to be located between keeper 63 and adjusting set 64.When needing to adjust the compress variation of spring 61, rotatable guiding
Bar 62, match somebody with somebody to merge with the screw thread of guide rod 62 due to adjusting set 64 and be close to locking closure 3, adjusting set 64 will not rotation synchronous with guide rod 62
Turn, but moved up and down along guide rod 62.The elastic parts 6 of this kind of form is simple in construction, compact, and space-consuming is few, regulation side
Just, it is easy on the rule vehicle of city that on-vehicle parts are more, are used between part under the compact operating mode in space.
In the present embodiment, positioning hole 51 and the adjustment hole 52 connected with positioning hole 51 are provided with the first bearing pin 5, is adjusted
The aperture in hole 52 is less than the aperture of positioning hole 51, and the one end of guide rod 62 is supported in positioning hole 51 and the end end is recessed provided with adjusting
Groove（Can be common flat recess, cross recess etc. not shown in figure）.When needing rotary steering bar 62, screwdriver is stretched into regulation
Hole 52 is interior and is directed at adjusting grooves.
In the present embodiment, coordinated between guide rod 62 and positioning hole 51 by slope 7, on the slope 7 of guide rod 62
It is circumferentially arranged to have a plurality of fin 8, it can prevent guide rod 62 from being spinned under spring 61 and effect of vibration, cause coupling mechanism force to decline.
As further preferred technical scheme, the slope 7 of positioning hole 51 is polished coarse, further improve guide rod 62 and positioning
Frictional force between hole 51, prevent guide rod 62 from rotating naturally, when needing to adjust spring force, bottle opener needs firmly to press, and makes
Guide rod 62 is separated with positioning hole 51 so as to reduce friction, facilitates rotary steering bar 62.
In the present embodiment, adjusting set 64 is provided with the suspension ring 9 for being used for being connected with tensiometer.It is easy to intuitively survey by tensiometer
Measure the elastic force of spring 61.
As shown in figure 5, the coupling mechanism force of hasp lock can periodic measurement, be measuring method and principle below：
Dig opening lock upwards first by locking closure 3, the suspension ring 9 that adjusting set 64 is then caught on tensiometer hook pull up,
Opening position when on lock where the first bearing pin 5 is moved to always to stop（When on lock, the institute of first bearing pin 5 under the effect of connecting rod 4
It is to determine in position, and also correlated identities can be set in the opening position）, read pulling force size data, you can know spring
61 spring force size FBullet（Herein because part weight itself and frictional force are much smaller than spring force, can be neglected）.
Force analysis：First bearing pin 5 is by 3 power, and 1）Spring 61 is delivered to the power on the first bearing pin 5 by guide rod 62
FBullet, i.e., tensiometer measurement power；2）Connecting rod 4 is to pulling force F caused by the first bearing pin 5Draw, case lid is each to the pressure of casing and takes
The F of padlockDrawSum；3）Waist-shaped hole 31 on locking closure 3 is to its caused pressure FPressure, and the structure from locking, FBulletAnd FPressureSide
To vertical, FBulletAnd FDrawThe angle in direction is 180 °-θ.This three power sums are 0, it can be seen from the parallelogram law of power：
FDraw=FBullet/cosθ（1）
The regulation of coupling mechanism force：The compression distance of spring 61 changes its spring force and also changed immediately.By formula（1）Hasp lock can be obtained
Coupling mechanism force is also with change.After regulation again by tensiometer testing result judge whether to adjust it is qualified.
Embodiment two
The present embodiment is that elastic parts 6 includes spring 61 and is fixedly arranged on locking closure 3 with the difference of embodiment one
Keeper 63, the both ends of spring 61 are connected with the bearing pin 5 of keeper 63 and first respectively, namely spring 61 uses extension spring, structure
Relative simplicity, it can also realize the regulation of coupling mechanism force.
