Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
What accompanying drawing 1-6 label 1-24 was indicated is key 1, locking closure 2, bearing pin 3, clamping block 4, shifting block 5, spring 6, bayonet socket 7, position-limited lever 8, lock base 9, block 10, platform 11, transmission body 12, key slot 13, key engagement cover 14, adjustment hole 15, stationary axle 16, round boss 17, the gear teeth 18, guiding drive block 19, protruding fixture block 20, guiding slotted eye 21, gear grooved 22, engaging groove 23, engaging tooth 24.
Be the structural representation of the utility model angular travel valve mechanical lock as shown in Figure 1.As seen from Figure 1, this angular travel valve mechanical lock mainly comprises two groups of locking devices of locking closure 2, lock base 9 and transmission body 12 and bilateral symmetry setting thereof etc.Wherein, transmission body 12 is passed and is bearing in locking closure 2 and locks on the base 9.Locking closure 2 is provided with the adjustment hole 15 of the auxiliary observation of tool, regulating action.In the present embodiment, transmission body 12 is fixed on the lock base 9, and transmission body 12 can be around its central shaft rotation.The platform 11 that one radial protrusion is arranged on transmission body 12 excircles offers a bayonet socket 7 on the platform outward edge, platform 11 lateral spacings one phase bit is provided with two blocks 10, and the turning circle that is positioned at two blocks 10 in the lock base 9 is provided with a position-limited lever 8.Forward another block 10 position that contacts with position-limited lever 8 to from arbitrary block 10 position that contacts with position-limited lever 8, the angle that transmission body 12 turns over is 90 degree.
Two groups of locking devices of angular travel valve mechanical lock promptly have mutually same lock set to decide device respectively in transmission body 12 both sides according to transmission body 12 bilateral symmetry apportions.Locking device comprises bearing pin 3, clamping block 4, shifting block 5 etc.The angular travel valve mechanical lock has two bearing pins 3, and apportion abuts against transmission body 12 both sides, and with the parallel axes of transmission body 12, an end firm fixation of bearing pin 3 is on lock base 9.One end of clamping block 4 is hinged on the bearing pin 3, can be around bearing pin 3 rotations.In conjunction with Fig. 4 be clamping block structural representation as seen, the surface of the other end of clamping block 4 offer the guiding slotted eye 21, the guiding slotted eye 21 are through holes, be profiled holes.One side of the close transmission body 12 of clamping block 4 same ends has a protruding fixture block 20, and protruding fixture block 20 is suitable with the bayonet socket 7 on the platform outward edge.
Clamping block 4 one ends are articulated on the bearing pin 3, and the other end is connected with 5, two shifting blocks of shifting block and is listed in transmission body 12 both sides 5 same branches.Fig. 2, Fig. 3 are respectively the plan view and the plan views of shifting block, shifting block 5 is mainly formed by the stationary axle 16 of lower end and around the round boss 17 that stationary axle 16 can be done to rotate, stationary axle 16 is fixed on the lock base 9, there are some gear teeth 18 side of round boss 17, round boss 17 upper surface non-central locations have a guiding drive block 19, and guiding drive block 19 is structure as a whole with round boss 17.When round boss 17 rotated, driving with round boss 17 had the guiding drive block 19 of certain radial distance to make circular movement.Because the guiding drive block 19 on the shifting block 5 is inserted in the guiding slotted eye 21 of clamping block 4, guiding drive block 19 is made circular movement and then promotes clamping block 4 to move together, and the relative movement orbit between guiding drive block 19 and the clamping block 4 is slotted eye 21 profile traces of profiled holes just that leads.
In addition, between clamping block 4 bottoms of the gear teeth 18 of the shifting block 5 of transmission body 12 1 sides and opposite side, be connected with spring 6, help resetting of the gear teeth 18 on the shifting block 5.
In the both sides of lock body, offer key slot 13 respectively with the gear teeth 18 corresponding positions on the shifting block 5, be inserted with key 1 in the key slot 13, accompanying drawing 5 is plan views of key.The lower end surface of key 1 offer with shifting block on the plurality of teeth race 22 that is complementary of the gear teeth 18.The key body side direction also offers some engaging grooves 23, in the present embodiment, as shown in Figure 5, offers two parallel engaging grooves 23.Engaging groove 23 matches with the engaging tooth 24 of key engagement cover 14.Fig. 6 is the structural representation of key engagement cover 14.As shown in fig. 1, key engagement cover 14 is embedded in the key slot 13, and key need pass key engagement cover 14, could insert fully in the key slot 13.Key engagement cover 14 inner cavity shapes size and key front end cross-sections match.Key engagement cover 14 is provided with the engaging tooth 24 of some projectioies, and engaging tooth 24 numbers are corresponding with engaging groove 23 numbers and the position of key with the position setting in the key engagement cover 14, thereby make key have encoding function.Reduce different keys and can open the rate of answering out of a lock.
When key 1 can detach in the key slot 13 fully, be the gear teeth 18 on the shifting block 5 when not contacting with gear grooved 22, at this moment, wherein a block 10 just touches position-limited lever 8, bayonet socket 7 is arranged in the travel path of a protruding fixture block 20 just, and the two can match.Protruding fixture block 20 on the clamping block 4 and the bayonet socket 7 on the platform outward edge are near coincideing, and after just key 1 detached, moving body 12 can not be moved by locked.
Do not considering under the correlation interference situation of remaining part, when key 1 in the key slot 13 in the drive-in step, by the gear movement between the gear teeth 18 on gear grooved 22 and the shifting block 5, driving shifting block 5 rotates around stationary axle 16, and then by 4 motions of guiding drive block 19 drive clamping blocks, make protruding fixture block 20 on the clamping block 4 away from bayonet socket 7, moving body 12 is in free working state.By the relevant parameter of precise design as spacing of the profile traces of the spacing of guiding drive block 19 and central shaft, profiled holes and protruding fixture block 20 and bayonet socket 7 or the like, guarantee when key 1 is advanced in the key slot 13 fully, projection fixture block 20 can not interfered away from bayonet socket 7, the rotatablely moving of impede motion body 12.
When the key 1 of transmission body 12 1 sides inserted the key slot 13 outside lock body fully, protruding fixture block 20 lifted, away from bayonet socket 7.Because wherein a block 10 just touches position-limited lever 8, transmission body 12 and former direction counterrotating.After transmission body 12 turned over 90 degree phase angles, this moment, another block then just touched position-limited lever 8.At this moment, if the key of opposite side detaches, the protruding fixture block and the bayonet socket 7 that then drive on the clamping block 4 of this side just match.
When the key of both sides all inserts in the key slot fully, then transmission body 12 rotatable motions, after the key of any side detached fully, then transmission body 12 can not be moved by locked.The key of opposite side is if also detach action, then drive protruding fixture block 20 near platform 11, until being resisted against on the platform 11, because this side does not have bayonet socket, the movement travel of locking device fails to finish, also there is engagement between the gear teeth 18 on the shifting block 5 and the gear grooved on the key 22, makes key can not detach key slot 13 fully, cannot be extracted fully.That is to say, extract any key, all will cause transmission body 12, must insert two keys simultaneously, just can open lock, can effectively prevent the generation of improper operation by locked.
