Detailed Description

Referring to fig. 1-53, the present invention provides a technical solution: an interlocking pin tumbler idling lock head and a key thereof;

referring to fig. 1, 2, 3 and 4, an interlocking pin tumbler cylinder includes a housing assembly 1, an inner plug assembly 2, an outer plug assembly 3 and an output assembly 4, and a mating key assembly 5.

Referring to fig. 1, the lock case assembly 1 comprises a lock case body 11, a snap ring 12, a first knock spring 13, a second knock spring 14, a first knock ball 15, a second knock ball 16 and a lock case insert 17; wherein the first pressing mechanism in the first spring hole 119 is a fixed first ball-ejecting spring 13 and a fixed first ball-ejecting spring 15, and the second spring hole 119 ^* The second internal pressing mechanism is a second fixed ball spring 14 supported on the lock housing insert 17 and a second ball 16 pressing the first ball 15 against the side post 214 and the second ball 16 against the lost motion pin 32, thereby urging the side post 214 and lost motion pin 32 radially inwardly of the lock housing body 11.

Referring to fig. 1, 7, 8 and 9, the housing body 11 defines a tubular opening 111 extending the length thereof, the tubular opening 111 being shaped to receive the cylindrical internal cylinder assembly 2 and including a shoulder 113 around the opening 112, the shoulder 113 engaging a flange 2112 on one end of the front internal cylinder 211 as shown in fig. 6.

Referring to fig. 7 and 9, the rear end of the housing body 11 is configured to receive an outlet slot 114 of the outer cylinder assembly 3 having a diameter greater than the opening 112. Therefore, the tubular opening of the lock shell body for receiving the lock core component is of a structure with a small outside and a large inside, the design effectively strengthens the structure of the lock shell in the direction of the key hole, and can effectively overcome the defect that the existing lock head has poor anti-theft performance when the lock cylinder is violently opened by using high-strength illegal keys through drilling, twisting, prying and other means. When a key is inserted without a key or an incorrect key is inserted, the side columns 214 are pushed radially outward of the inner plug assembly 2 by the first combined snap ring pins 231 and the second combined snap ring pins 232, the side columns 214 push the idle lock pins 32 radially outward, the rotational lock of the inner plug assembly 2 with respect to the outer plug assembly 3 is released, the inner plug assembly 2 can be rotated arbitrarily, and at the same time, as shown in fig. 9 and 13, the idle lock pins 32 are engaged with the lock pin grooves 115 to rotationally lock the outer plug 31 with respect to the housing body 11, and at this time, the rotation of the inner plug assembly 2 cannot drive the output assembly 4 fixed to the outer plug assembly 3. And the prior cam or connecting rod mechanism connected with the output component 4 can not be driven to adjust the lock bolt to the unlocking position, thereby achieving the purpose of illegal unlocking. Referring to fig. 7 and 9, the tubular opening 111 is provided with two annular grooves 116 in the middle section, which extend circumferentially around the inner wall surface of the tubular opening 111. When the outer plug assembly 3 is in a rotation locked state with respect to the lock housing assembly 11, the first diameter changing mechanism 230 is pushed by the first locking mechanism 220 radially outwardly of the inner plug assembly 2. And the second diameter changing mechanism 250 is pushed outward in the radial direction of the inner plug assembly 2 by the second locking mechanism 240, and the first diameter changing mechanism 230 and the second diameter changing mechanism 250 are engaged with the annular groove 116, respectively. So that the inner plug assembly 2 remains in the assembled condition shown in figure 6.

Referring to fig. 1, 7, 9 and 22, the lock housing body 11 includes dovetail slots 118 extending along its sides and a snap ring slot 117 extending radially inwardly therefrom and communicating with the tubular opening 111, a first spring aperture 119 and a second spring aperture 119 ^* . When the snap ring 12 is engaged with the snap ring groove 117 on the side of the lock case body 11, the snap ring 12 is engaged with the outer cylinder stopper groove 311 of the outer cylinder 31 to keep the outer cylinder assembly 3 in the assembled state shown in fig. 9 and 22. The dovetail slots 118 are now aligned with the snap ring retaining slots 122 on the sides of the snap ring 12, and insertion of the lock housing insert 17 into the dovetail slots 118 maintains the snap ring 12 in the assembled condition shown in figures 9, 11, 22 and 23. The inside of the snap ring 12 is also provided with a snap ring internal groove 121, and when the lock is in a locked state, the lost motion lock pin 32 is snapped into the snap ring internal groove 121.

Referring to fig. 6, 9 and 22, the outer surface of the lock housing body 11 is provided with an outer mark 110 at a position corresponding to the lost motion pin 32, the outer mark 110 is capable of cooperating with an inner mark 2111 on the outer surface of the front inner cylinder 211 to align the lost motion pin 32 with the jamb 214 before the proper key is inserted to facilitate unlocking and to increase the key amount of the lock by staggering the lost motion pin 32 in the locked state. In the illustrated embodiment, the triangular indicia on the outer surface of the housing body 11 indicates the position of the lost motion pin 32 and the triangular indicia adjacent the circular indicia on the outer surface of the front inner cylinder 211 indicates the position of the jamb 214 when the lock is in the assembled condition. Such design can compensate the defect that the key of current idle running lock core is adjusted the efficiency poor effectively, improves the efficiency of unblanking, makes things convenient for people to use.

Referring to fig. 1, 2, 8, 9, 10, 21 and 22, the internal cylinder assembly 2 includes a front internal cylinder 211, a middle internal cylinder 212, a rear internal cylinder 213, a jamb 214, a first locking mechanism 220, a first diameter changing mechanism 230, a second locking mechanism 240 and a second diameter changing mechanism 250.

Referring to fig. 2 and 10, the front internal cylinder 211 includes a plurality of tumbler front openings 2113 which extend through the front internal cylinder 211 in the axial direction thereof and are arranged in a circular pattern. The key hole design can effectively overcome the defect of poor anti-theft performance when a straight key hole or a key hole with a similar shape is violently opened by means of drilling, twisting, prying and the like for a lock core by using a high-strength illegal key. Referring to fig. 8, 9, 10, 21 and 22, the other end of the front inner cylinder 211 is configured to receive a front cavity 2115 of a flange neck 2125 on the front end of the middle inner cylinder 212, and a plurality of equally sized teeth 2114 are provided along the inside surface of the front cavity 2115, the teeth 2114 engaging with concave teeth 2124 on the outside surface of the flange neck 2125 on the end of the middle inner cylinder 212, the front inner cylinder 211 being interlockable with the middle inner cylinder 212 in the assembled state. Such a design allows for a simple increase in the key amount of the lock cylinder without changing the pin recess locations and pin sequencing of the internal toggle pins and interlocking pins by adjusting the mating positions of male teeth 2114 and female teeth 2124 to reposition internal marks 2111 on the surface of front inner plug 211 and side post grooves 2120 of receiving side posts 214 on the surface side of middle inner plug 212, such as aligning square marks on the outer surface of front inner plug 211 with side post grooves 2120.

Referring to fig. 10 and 19, the bottom of the front cavity 2115 and the plane of the flange neck 2125 on the middle inner cylinder 212 that engages it are configured to receive the pentagonal notch 2116 of the first locking mechanism 220 and the first locking mechanism cavity 2121. The bottom of the first locking mechanism cavity 2121 is defined by a set of toggle pin rear openings 2123 having a diameter slightly larger than the diameter of the circular cross-section of the first locking mechanism 220. And a crank pin spring slot 2128 that receives the crank pin spring 226. In the assembled state, the individual crankpins are therefore simultaneously urged axially outwardly by the crankpin springs and the interlocking pin springs, without interfering with one another.

Five crank pin spacing posts 212 circumferentially disposed in the first locking mechanism cavity 2121 ^* And (3) outside. Taking the third toggle pin 223 as an example, the pin shank on one side is in the shape of a smooth cylinder, and the diameter of the cross-sectional circle is slightly smaller than the diameter of the toggle pin front opening 2113 on the front inner plug 211. The cylindrical side of the pin shank on the other side is provided with a crank pin groove 2200 that mates with the snap ring pin tooth 2300, as will be described in detail later. And the other first toggle pin 221, second toggle pin 222, fourth toggle pin 224, and fifth toggle pin 225 are all configured to mate with combination snap ring pins, but the distance between the toggle pin slot 2200 on the cylindrical side of the pin shank to the toggle is related to the key setting of the key rack assembly 530. The design effectively makes up the defect that the existing lock cylinder is easy to be shifted one by one to test, so that the lock cylinder is cracked to be unlocked.

Referring to FIGS. 8, 9, 10, 21 and 22, the other end of the central internal cylinder 212 is a second lock structure cavity 2127 for receiving the second lock structure 240 and the bottom of the cavity has a front spindle opening 2121 for receiving the spindle 246 ^* . The side of the middle internal cylinder 212 is circumferentially provided with a circular diameter reducer groove 2129 and three front bullet group spring grooves 2126 that receive the first diameter reducer 230 and the combination snap ring bullet group spring 236. The wedge pin grooves include a front wedge pin groove, a middle wedge pin groove 2122, and a rear wedge pin groove 2132; the two sides of the diameter-changing mechanism groove 2129 are provided with front wedge pin grooves (not released in the figure) which are radially inward along the middle inner lock cylinder 212 and receive the wedge pins 2303 of the first diameter-changing mechanism 230, the front wedge pin grooves are circumferentially distributed on the two sides of the diameter-changing mechanism groove 2129 and play a role in orienting the wedge pins 2303 of the first diameter-changing mechanism 230, and the effect of the front wedge pin grooves is equal to the effect of orienting the wedge pins 2303 of the second diameter-changing mechanism 250 by the middle wedge pin grooves 2122 and the rear wedge pin grooves 2132The fruit is consistent. The side of the middle inner cylinder 212 is provided along its axial direction with a side post groove 2120 that receives the side post 214. And the rear end of the middle internal cylinder 212 is also provided with a middle wedge pin recess 2122.

Referring to fig. 2, 8, 9, 10, 21 and 22, one end of the rear internal cylinder 213 is configured to receive the rear cavity 2133 of the second lock structure 240 and the rear wedge pin recess 2132 of the second diameter reducing mechanism 250. And a rear spindle hole 2134 for receiving the spindle 246 is provided at a central position of a bottom surface thereof. The side surface of rear interior plug 213 is configured to receive rear set of ball springs 2135 of combination snap ring ball springs 236 and T-grooves 2131 in the axial direction configured to receive side posts 214. The number of the spring grooves of the bullet group is 4, and the spring grooves are symmetrically distributed on both sides of the first diameter changing mechanism 230 and the second diameter changing mechanism 250, so that the wedge pins 2303 are pressed inward by the spring plates 2361. As shown in fig. 2, 8, 9, 21 and 22, second reducing mechanism 250 between middle inner cylinder 212 and rear inner cylinder 213 has a coupling function to allow the middle inner cylinder 212 and rear inner cylinder 213 to rotate coaxially, in addition to its inherent function of controlling the position of side post 214 and maintaining inner cylinder assembly 2 in the assembled state when in the locked state.

In the illustrated embodiment, referring to fig. 1, 2, 31, 32, 33, 34, 35, and 36, first diameter change mechanism 230 and second diameter change mechanism 250 each include a first combination snap ring pin 231, a second combination snap ring pin 232, a third combination snap ring pin 233, a fourth combination snap ring pin 234, and a fifth combination snap ring pin 235. Taking the fifth combined snap ring pin 235 as an example, snap ring pin teeth 2300 are arranged inside the semicircular combined snap ring pin, and two sides of the semicircular combined snap ring pin are respectively provided with a wedge-shaped pin 2303 which is slightly smaller than a front wedge-shaped pin groove, a middle wedge-shaped pin groove 2122 and a rear wedge-shaped pin groove 2132. For example, a set of pressing teeth 2301 and a pressing groove 2302 are respectively provided at both ends of the fifth combined snap ring pins 235, the pressing teeth 2301 and the pressing groove 2302 constitute the entire pressing mechanism, and the pressing teeth 2301 and the pressing groove 2302 of different combined snap ring pins can be engaged with each other to complete pressing. Referring to fig. 2, 16 and 28, the respective wedge pins of the second diameter changing mechanism 250 are urged radially inward by the spring plate 2361 of the combined snap ring spring set 236.

While biasing teeth 2301 and biasing grooves 2302 of fifth combination snap ring pin 235 at both ends mate biasing teeth 2301 and biasing grooves 2302 of third combination snap ring pin 233 and fourth combination snap ring pin 234 adjacent thereto, such that both are biased radially outward and engaged in annular groove 116. Similarly, third and fourth combination snap ring pins 233 and 234 urge first and second combination snap ring pins 231 and 232 radially outward via urging teeth 2301 and urging grooves 2302 thereof, which causes first and second side post urging protrusions 2311 and 2321 to urge side post 214 radially outward and to retain outer plug 31 rotationally locked with respect to housing body 11 by urging lost motion locking pin 32 radially outward such that lost motion locking pin 32 is captured in locking pin groove 115.

Referring to fig. 21, 22 and 26, also taking the fifth combination snap ring pin 235 as an example, when the proper key is placed in the tumbler front opening 2113 of the inner plug assembly 2, the combination snap ring pin spring 236 urges the first diameter changing mechanism 230 radially inward as the first locking mechanism 220 is axially moved sequentially to the unlocked position in response to insertion of the key. When the snap ring pin teeth 2300 of the combined snap ring pin are engaged with the crank pin grooves 2200, and the snap ring pin teeth 2300 of the first diameter changing mechanism 230 are simultaneously engaged with the corresponding crank pin grooves 2200 of the first locking mechanism 220, the combined snap ring pin spring 236 pushes and engages the first diameter changing mechanism 230 inward in the radial direction to the inner side of the annular groove 116, the first side post pushing protrusions 2311 and the second side post pushing protrusions 2321 of the first combined snap ring pin 231 and the second combined snap ring pin 232 are aligned with the side post grooves 2120 of the middle inner lock cylinder 212. Referring to fig. 23, 21, 25, 26 and 27, side post 214 is urged radially inwardly along lock housing body 11 by first ball 15 into engagement with first side post push protrusion 2311, second side post push protrusion 2321 and side post slot 2120. At the same time, the idle lock pins 32 are also pushed inward by the second knock balls 16 along the radial direction of the lock case body 11, and are engaged with the outer cylinder grooves 312 of the outer cylinder 31 and the side T-grooves 2131 of the rear inner cylinder 213, so that the rotation key assembly 5 can drive the inner cylinder assembly 2 and the outer cylinder assembly 3 to rotate simultaneously, and drive the output assembly 4 connected to the outer cylinder assembly 3. Meanwhile, the output component 4 drives the existing cam or connecting rod connected with the output component to adjust the lock tongue to the unlocking position, so that the unlocking action is realized.

Therefore, the interlocking relationship between the individual combined snap ring pins constituting the first diameter changing mechanism 230 and the second diameter changing mechanism 250 defines that the rotational lock state of the outer plug 31 with respect to the housing body 11 can be released only when all the toggle pins are moved to the unlock position. That is, in the illustrated embodiment, the state of the side post 214 is not limited to only the first reducing mechanism 230 interlocked with the first locking mechanism 220, but is also limited by the other set of second reducing mechanisms 250 interlocked with the second locking mechanism 240.

Referring to fig. 2 and 3, in the illustrated embodiment, the second locking structure 240 includes a first interlocking pin 241, a second interlocking pin 242, a third interlocking pin 243, a fourth interlocking pin 244, a fifth interlocking pin 245, a main shaft 246, a rear collar 247, a front collar 248, and an interlocking pin spring 249.

Referring to fig. 2, 8 and 9, the interlocking pins may be combined into a tube having an outer diameter slightly smaller than the inner diameter of the second locking structure cavity 2127, with grooves, such as first interlocking pin grooves 2411, provided at different locations on the outer side of each interlocking pin to mate with the combined snap ring pins. As shown in fig. 12, and is provided with a semicircular groove on its outer side surface in the axial direction for engaging with the orientation teeth 2120 of the middle inner cylinder 212 ^* In cooperation, the second locking structure 240 is constrained to reciprocate only in an axial direction. Referring to fig. 3, 16 and 17, rear collar 247 and front collar 248 contain a hole that fits over the diameter of main shaft 246 through which the two collars are connected in series to main shaft 246. Each lantern ring also comprises lantern ring teeth which can be matched with two vertical U-shaped track grooves formed by mutually communicated and combined by the guide protrusions on the inner side surfaces of the interlocking marbles. In the locked state, see fig. 37, 38, 39, 40, 41 and 42, the teeth of the rear 247 and front 248 collars are each in a respective positionThe center position of the guide projection of the interlocking pin.
