Abstract

The utility model discloses dual fail-safe handcuffs, which are composed of handcuffs rings, anti-drop blocking gears, springs, anti-drop rivets, probes, lock cylinders, lock gates and probe keys. A cross-shaped groove and a semi-circle groove are respectively arranged at the corresponding positions of the inner sides of the two lock cylinders, blocking teeth matched with the anti-drop blocking gears are arranged on the lower portion of the anti-drop blocking gears, and gaps are reserved in the middles of the lower portions of the blocking teeth. A rotating transmission device is arranged below the blocking teeth, and the rotating transmission device is anticlockwise rotated 90 degrees to be contacted with the blocking teeth. The probes penetrate the rotating transmission device to be arranged inside the rotating transmission device, and slide and rotate in the cross-shaped grooves inside the two lock cylinders. Holes are arranged on the probe keys. The dual fail-safe handcuffs have the advantages of being simple in structure, convenient to use, high in practical applicability and safe and reliable. Only specific probe keys can open the dual fail-safe handcuffs.

Description

The dual fail-safe handcuffss

Technical field

The utility model relates to a kind of dual fail-safe handcuffss, a kind of dual fail-safe handcuffss of especially being made up of handcuffss ring, anticreep latch wheel, spring, anticreep rivet, probe, lock core, stop, 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 as everyone knows are common handcuffss, 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, thereby the convict escapes, and possibly threaten social safety, and the arresting of public security officer, efficient on duty are affected.

Summary of the invention

The purpose of the utility model provides a kind of simple in structure, easy to use, practical, safe and reliable, dual fail-safe handcuffss of needing the particular probe key to open.

For realizing above-mentioned purpose; The dual fail-safe handcuffss of the utility model are made up of handcuffss ring, anticreep latch wheel, spring, anticreep rivet, probe, lock core, stop, probe key, and two inboard relative positions of lock core have a cross recess and a semicircle groove; Anticreep latch wheel below is equipped with the latch that matches with anticreep latch wheel, leaves the slit in the middle of the bottom of latch; The below of latch is equipped with a rotary actuator, and rotary actuator is rotated counterclockwise 90 ° and contacts with latch; Probe passes the inside that rotary actuator is installed in rotary actuator, in the inner cross recess of two stops, slides and rotation; The probe key has the hole.

The left side of latch is equipped with a spring.

The anticreep rivet is fixed on the upper end of rotary actuator.

The bottom of rotary actuator has interior five jiaos of grooves.

Probe is T-Type structure.

Outer five jiaos of interior five jiaos of grooves with the rotary actuator bottom at probe key top cooperatively interact.

After adopting the utility model dual fail-safe handcuffss structure, rotary actuator is rotated counterclockwise and stretches in the middle space, latch below, pins anticreep latch wheel, plays the effect of locking; The T-shaped probe passes the inside that rotary actuator is installed in rotary actuator; Make that rotary actuator can not be with being intended to the inner rotation of lock core, and then can't arbitrarily open and anti-ly shake off gear to have only the probe key of specific hole depth could probe be depressed into the center of the inboard cross recess of two lock cores; Probe could rotate in groove; Make rotary actuator turn clockwise latch is pressed, thereby open the anti-latch of shaking off, open handcuffss; The utility model dual fail-safe handcuffss have two-way safeguarding function; Have only the probe key of specific hole depth could open handcuffss, have safe and reliable advantage; And has simple in structure, easy to use, practical advantage.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

Fig. 1 is made up of handcuffss ring 1, anticreep latch wheel 2, spring 4, anticreep rivet 5, probe 6, lock core 8, stop 9, probe key 10 to dual fail-safe handcuffss shown in Figure 4, and two lock core 8 inboard relative positions have a cross recess and a semicircle groove; The anticreep latch is taken turns 2 belows the latch 3 that matches with anticreep latch wheel 2 is installed, and leaves the slit in the middle of the bottom of latch 3; The below of latch 3 is equipped with a rotary actuator 7, and rotary actuator 7 is rotated counterclockwise 90 ° and contacts with latch 3, has pressed latch 3; Probe 6 passes the inside that rotary actuator 7 is installed in rotary actuator 7, in two lock cores, 8 inboard cross recess, slides and rotation; Probe key 10 has the hole, has only the probe key 10 of specific hole depth could open the dual fail-safe handcuffss; The left side of latch 3 is equipped with a spring 4, plays the effect of the latch 3 that resets; Anticreep rivet 5 is fixed on the upper end of rotary actuator 7, plays the effect of fixing spring 4; The bottom of rotary actuator 7 has interior five jiaos of grooves; Probe 6 is T-Type structure; Driven rotary transmission device 7 rotation that cooperatively interacts of outer five jiaos of interior five jiaos of grooves at probe key 10 tops with rotary actuator 7 bottoms.

During use, in interior five jiaos of grooves of outer five jiaos of insertion rotary actuator 7 bottoms at probe key 10 tops of specific hole depth, probe 6 receives the pressure of the probe key 10 of specific hole depth; Probe 6 moves to the position, center of two lock core 8 inboard cross recess; At this moment the probe key 10 that turns clockwise makes it half-twist, and driven rotary transmission device 7 turns clockwise in the semicircle groove of two lock cores 8 90 °; After rotary actuator 7 turns clockwise 90 ° and touches latch 3; Latch 3 has been pressed the interlock that makes latch 3 disengaging anticreep latch wheels 2, and handcuffss ring 1 will be realized freely rotating like this, open probe pressure dual fail-safe handcuffss.Probe pressure dual fail-safe handcuffss are transferred to when locking state by opening; Earlier handcuffss ring 1 is stretched into anticreep latch wheel 2 and make the two interlock in position; Position, center at two lock core 8 inboard cross recess; Rotating probe key 10 driven rotary transmission devices 7 turn clockwise in the semicircle groove of two lock cores 8 360 ° together, rotary actuator 7 are stretched in the slit of latch 3 bottoms, and meanwhile latch 3 resets under the effect of spring 4 and latch is taken turns 2 engaged; At this moment handcuffss ring 1 can't rotate; Probe key 10 is extracted, and T-shaped probe 6 is slipped to the cross recess bottom of two lock cores, 8 inboards under the effect of spring 4, realize that so far the dual fail-safe of dual fail-safe handcuffss is locked.
