Description
Technical field
The utility model relates to a kind of three insurance handcuffss, especially a kind of three insurance handcuffss of being made up of handcuffss ring, stop, latch wheel, power assistant spring, spring, connecting pin, handcuffss connection chain, probe key.
Background technology
Handcuffss are the most frequently used and requisite as the fetters that uses in the enforcing law.The handcuffss great majority that use in China's public security, judicial department are common handcuffss as everyone knows, the unlatching of common handcuffss and the principle of locking all single employing lock.This common handcuffss are simple in structure, easy to use, but also exist the convict to use article such as iron wire, pin, waddy to realize the problem of the unlatching of handcuffss, and only need a people just can realize, thereby the convict escapes, may threaten social safety, the arresting of public security officer, efficient on duty are affected.
Summary of the invention
The purpose of this utility model provides the three insurance handcuffss that a kind of simple in structure, easy to use, practical, safe and reliable and people can't open handcuffss.
For achieving the above object, three insurance handcuffss of the present utility model are made up of handcuffss ring, stop, latch wheel, power assistant spring, spring, connecting pin, handcuffss connection chain, probe key, and latch wheel below is equipped with the latch that matches with the latch wheel; The inferoanterior of latch is equipped with a rotary sleeve, and the upper and lower of rotary sleeve is respectively equipped with four grooves; Drive link is installed in the right-hand member of rotary sleeve top; Be provided with four slideways in the rotary sleeve; Probe is installed in the slideway place of rotary sleeve; Two insurance pellets shot from a slingshot stretch in the rotary sleeve by spring; One end of two pressure switches stretches into respectively in two grooves of rotary sleeve top, and an other end stretches out stop respectively; The upper end of auxiliary catch is stretched in two grooves of rotary sleeve below, and stop is stretched out in the lower end of auxiliary catch; The probe key has the hole.
The right side of latch is equipped with a power assistant spring.
Be separately installed with a power assistant spring in the middle of two pressure switches and the stop.
Be separately installed with a power assistant spring in the middle of two auxiliary catches and the stop.
Drive link is rotated counterclockwise 90 ° and contacts with latch, thereby has pressed latch.
Probe is decussate texture.
The rotation of working in coordination of outer five jiaos of interior five jiaos of grooves of probe key with rotary sleeve bottom.
After adopting the utility model three insurance handcuffss structures, because two insurance pellets shot from a slingshot and two pressure switches stretch in the rotary sleeve respectively, rotary sleeve can not rotate freely, and drive link is rotated counterclockwise in the 270 ° of spaces that can stretch into latch below, play the effect of locking, and then can not open handcuffss, and play the effect of three insurances, have safe and reliable advantage; Need the probe key owing to open handcuffss, also will press two pressure switches simultaneously,, can take precautions against escaping certainly of convict so a people can't open handcuffss; Because the probe key of the specific hole depth of needs simple in structure and press two pressure switches simultaneously and just can unblank, and owing to having three insurance functions, so easy to use, practical.

Fig. 2 is the schematic diagram of rotary sleeve.
Handcuffss ring 1, stop 2, latch wheel 3, latch 4, power assistant spring 5, drive link 6, rotary sleeve 7, spring 8, pressure switch 9, insurance pellet shot from a slingshot 10, probe 11, auxiliary catch 12, connecting pin 13, handcuffss connection chain 14, probe key 15.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1, three insurance handcuffss shown in Figure 2 are made up of handcuffss ring 1, stop 2, latch wheel 3, power assistant spring 5, spring 8, connecting pin 13, handcuffss connection chain 14, probe key 15, and latch is taken turns 3 belows and is equipped with and latch wheel 3 latches that match 4; The inferoanterior of latch 4 is equipped with a rotary sleeve 7, and the upper and lower of rotary sleeve 7 is respectively equipped with four grooves; Drive link 6 is installed in the right-hand member of rotary sleeve 7 tops; Be provided with four slideways in the rotary sleeve 7; Probe 11 is installed in the slideway place of rotary sleeve 7; Two insurance pellets shot from a slingshot 10 stretch in the rotary sleeve 7 by spring 8; One end of two pressure switches 9 stretches into respectively in two grooves of rotary sleeve 7 tops, and an other end stretches out stop 2 respectively; The upper end of auxiliary catch 12 is stretched in two grooves of rotary sleeve 7 belows, and stop 2 is stretched out in the lower end of auxiliary catch 12; Probe key 15 has the hole, has only the probe key 15 of specific hole depth two insurance pellets shot from a slingshot 10 could be ejected rotary sleeve 7, and then could open and lock three insurance handcuffss; The right side of latch 4 is equipped with a power assistant spring 5, plays the effect of the latch 4 that resets; Two pressure switches 9 are separately installed with a power assistant spring 5 with stop 2 centres, play the effect of reseat pressure switch 9; Two auxiliary catches 12 are separately installed with a power assistant spring 5 with stop 2 centres, play the effect of two auxiliary catches 12 that reset; Drive link 6 is rotated counterclockwise 90 ° and contacts with latch 4, thereby has pressed latch 4; Probe 11 is decussate texture; The rotation of working in coordination of outer five jiaos of interior five jiaos of grooves of probe key 15 with rotary sleeve 7 bottoms.
During use, when the probe key 15 of specific hole depth inserts interior five jiaos of grooves of rotary sleeves 7 bottoms, lift two auxiliary catches 12, two grooves that make two auxiliary catches 12 break away from rotary sleeve 7 belows, probe 11 is subjected to the pressure of the probe key 15 of specific hole depth, in slideway, move to two insurance pellet shot from a slingshot 10 places, two insurance pellets shot from a slingshot 10 are ejected rotary sleeve 7, meanwhile press two pressure switches 9, make two pressure switches 9 leave two grooves of rotary sleeve 7 tops, then probe key 15 is rotated counterclockwise 90 ° of driven rotary covers 7 and drive link 6 rotations, after drive link 6 half-twists touch latch 4, latch 4 has been pressed the interlock that makes latch 4 disengaging latch wheels 3, and handcuffss ring 1 will be realized freely rotating like this, open three insurance handcuffss.Three insurance handcuffss are transferred to when locking state by opening, earlier handcuffss ring 1 is stretched into latch wheel 3 and make the two interlock in position, rotating probe key 15 driven rotary cover 7 and drive link 6 turn clockwise 360 ° together then, drive link 6 is stretched in the space of latch 4 belows, meanwhile latch 4 resets under the effect of power assistant spring 5 and latch is taken turns 3 engaged, at this moment handcuffss ring 1 can't rotate, unclamp two pressure switches 9 then, two pressure switches 9 stretch in two other groove above the rotary sleeve 7 under the effect of two power assistant spring 5, simultaneously, extract probe key 15, under the effect of spring 8, probe 11 arrives the home position to lower slider in slideway, meanwhile, under the effect of two springs 8, two insurance pellets shot from a slingshot 10 reset and stretch into again in the rotary sleeve 7, and after probe key 15 broke away from two auxiliary catches 12, two auxiliary catches 12 were under the effect of power assistant spring 5, again stretch in two other groove of rotary sleeve 7 belows, realize that so far three insurances of three insurance handcuffss are locked.
