Description

Technical Field

[0001] This application relates to the field of anti-theft lock technology, and in particular to a two-way linkage lock. Background Technology

[0002] Traditional locks typically only allow for unidirectional locking. For large equipment or products requiring multiple locking points, multiple locks are needed. Unlocking then requires sequentially unlocking each lock, a cumbersome and time-consuming process. Utility Model Content

[0003] In view of this, this application proposes a two-way linkage lock to solve the technical problem that existing locks cannot complete locking or unlocking actions synchronously at multiple points.

[0004] One embodiment of this application discloses a bidirectional linkage lock, including a connecting rod, a first locking mechanism, and a second locking mechanism. A connecting pin is provided at one end of the connecting rod. The first locking mechanism is located at one end of the connecting rod and includes a lock head and a first latch sleeved on the lock head. The first latch is configured to rotate under the drive of the lock head and has a groove extending through it. The connecting pin passes through the groove and can move along the groove, thereby driving the connecting rod to move along its extension direction. The second locking mechanism includes a second latch, which is fixed to the end of the connecting rod away from the first locking mechanism.

[0005] In one embodiment, the bidirectional linkage lock further includes a limiting mechanism. The limiting mechanism includes at least one first fastener and at least one opening on the connecting rod, with each opening corresponding to one first fastener. The first fastener is fixed to the object to be locked and protrudes from the opening.

[0006] In one embodiment, the opening is a waist-shaped opening.

[0007] In one embodiment, the first locking tongue includes a first protrusion, a first inclined portion, a first connecting portion, a second inclined portion, and a second protrusion connected in sequence. The first protrusion is used to insert into or extend from the object to be locked, thereby achieving locking or unlocking. The first inclined portion extends at an angle and forms an angle with the first protrusion. The first connecting portion is sleeved on the outer peripheral surface of the lock head. The second inclined portion extends at an angle and forms an angle with the first connecting portion. The second protrusion is used to connect the connecting rod, and the sliding groove is provided in the second protrusion.

[0008] In one embodiment, the groove extends through the second protrusion along the thickness direction of the second protrusion, and the groove is an arc-shaped groove.

[0009] In one embodiment, the bidirectional linkage lock has a locked state. When the bidirectional linkage lock is in the locked state, the main plane of the first protrusion is parallel to the main plane of the connecting rod.

[0010] In one embodiment, the bidirectional linkage lock also has an unlocked state. When the bidirectional linkage lock is in the unlocked state, the main plane of the first protrusion is perpendicular to the main plane of the connecting rod.

[0011] In one embodiment, the second locking mechanism further includes a second fastener for securing the second locking tongue to the connecting rod.

[0012] In one embodiment, the second locking tongue includes a second connecting portion, a third connecting portion, and a third protrusion connected in sequence. The second connecting portion is fixed to the connecting rod by a second fastener. The third connecting portion is connected to one end of the second connecting portion and extends in a direction away from the connecting rod. The third protrusion is connected to the end of the third connecting portion away from the second connecting portion. The third protrusion is used to insert into or extend from the object to be locked, thereby achieving locking or unlocking.

[0013] In one embodiment, the cross-sections of the third connecting portion and the third protrusion are "L" shaped.

[0014] This application sets up a connecting rod that is movably connected to the first locking tongue (the connecting rod is movably connected to the first locking tongue through a slide groove and a connecting pin), and sets a second locking tongue on the connecting rod. This allows the rotation of the first locking tongue to drive the connecting rod to move, and the movement of the connecting rod to drive the movement of the second locking tongue. This allows one lock head to control the movement of the first and second locking tongues simultaneously, thereby enabling multiple points to be locked or unlocked synchronously. This simplifies operation and improves the efficiency of locking or unlocking. Attached Figure Description

[0029] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please see Figures 1 to 3 This application proposes a two-way linkage lock 100, which includes a connecting rod 10, a first locking mechanism 20, and a second locking mechanism 30. The first locking mechanism 20 and the second locking mechanism 30 are located at opposite ends of the extending direction of the connecting rod 10. The first locking mechanism 20 can be used to lock a certain point of the object to be locked, and the second locking mechanism 30 can be used to lock another point. One end of the connecting rod 10 is provided with a connecting pin 11, and the first locking mechanism 20 is movably connected to the connecting rod 10 through the connecting pin 11. The first locking mechanism 20 includes a lock head 21 and a first latch 22 sleeved on the lock head 21. The lock head 21 can be controlled to rotate by a key or other opening method. The first latch 22 can rotate under the drive of the lock head 21, for example, screwing into or out of the object to be locked, thereby completing the locking or unlocking action. The first locking tongue 22 has a groove 220 extending through it along its thickness. The connecting pin 11 passes through the groove 220 and can move along it, thereby driving the connecting rod 10 to move along its extension direction. The second locking mechanism 30 includes a second locking tongue 31, which is fixed to the end of the connecting rod 10 away from the first locking mechanism 20. When the connecting rod 10 moves under the action of the first locking tongue 22, the second locking tongue 31 fixed to the connecting rod 10 will also move, and the second locking tongue 31 will extend into or out of the object to be locked, thereby completing the locking or unlocking action synchronously with the first locking tongue 22.

[0031] By setting a connecting rod 10 movably connected to the first locking tongue 22 (the connecting rod 10 is movably connected to the first locking tongue 22 via a slide groove 220 and a connecting pin 11), and setting a second locking tongue 31 on the connecting rod 10, the rotation of the first locking tongue 22 can drive the connecting rod 10 to move, and the movement of the connecting rod 10 can drive the movement of the second locking tongue 31. That is, the bidirectional linkage lock 100 of this embodiment can simultaneously control the movement of the first locking tongue 22 and the second locking tongue 31 through a single lock head 21, thereby enabling multi-point synchronous locking or unlocking actions, simplifying operation and improving locking or unlocking efficiency.

[0032] In some embodiments, such as Figure 1As shown, the bidirectional linkage lock 100 also includes a limiting mechanism 40. The number of limiting mechanisms 40 can be one or more, and this application does not impose a limitation. Each limiting mechanism 40 includes at least one first fastener 41 and at least one opening 110 provided on the connecting rod 10, with each opening 110 corresponding to one first fastener 41. The first fastener 41 is fixed to the object to be locked, and the first fastener 41 protrudes from the opening 110. The first fastener 41 can be, but is not limited to, a screw. Through the cooperation of the first fastener 41 and the opening 110, the limiting mechanism 40 can restrict the movement of the connecting rod 10 in any direction, ensuring that the connecting rod 10 can only move along its extension direction, thus ensuring the stability of the connecting rod 10 during movement.

[0033] Furthermore, the opening 110 can penetrate the connecting rod 10 along its thickness direction, and multiple openings 110 can be spaced apart along the extension direction of the connecting rod 10. The opening 110 can be, but is not limited to, an oblong hole (also called an oblong hole), with arc-shaped surfaces at both ends and a parallel plane in the middle. The arrangement direction of the two arc-shaped surfaces (i.e., the extension direction of the parallel plane) is the extension direction of the connecting rod 10. When the connecting rod 10 moves under the action of the first locking tongue 22, the first fastener 41 passing through the opening 110 can restrict the arbitrary shaking of the connecting rod 10. The oblong hole shape of the opening 110 can ensure that the connecting rod 10 moves along the extension direction of the parallel surface of the opening 110, that is, ensure that the connecting rod 10 can only move along the extension direction of the connecting rod 10.

[0034] In some embodiments, such as Figure 2 As shown, the first locking tongue 22 includes a first protrusion 221, a first inclined portion 222, a first connecting portion 223, a second inclined portion 224, and a second protrusion 225 connected in sequence. The first protrusion 221 can be a thin sheet, which can be used to insert into or extend out of the object to be locked, thereby achieving locking or unlocking. The main plane of the first protrusion 221 (the surface perpendicular to the thickness direction, i.e.) Figure 2 The upper or lower surface of the first protrusion 221 can be approximately aligned with the principal plane of the connecting rod 10 (the surface perpendicular to the thickness direction, i.e.) Figure 1The upper or lower surface of the connecting rod 10 is generally parallel to the first inclined portion 222. The first protrusion 221 protrudes from the surface of the first inclined portion 222 in a direction away from the second latch 31. The first inclined portion 222 extends obliquely and forms an angle with the first protrusion 221. This angle can be acute, right, or obtuse, but it cannot be 0° or 180°. The first connecting portion 223 is fitted onto the outer peripheral surface of the lock head 21, thereby fixing the first latch 22 to the lock head 21. The second inclined portion 224 extends obliquely and forms an angle with the first connecting portion 223. This angle can be acute, right, or obtuse, but it cannot be 0° or 180°. The second protrusion 225 is used to connect the connecting rod 10, and a groove 220 is provided on the second protrusion 225. The second protrusion 225 protrudes from the surface of the second inclined portion 224 in a direction close to the second latch 31.

[0035] Furthermore, the groove 220 extends through the second protrusion 225 along the thickness direction of the second protrusion 225, and the groove 220 is an arc-shaped groove.

[0036] Understandably, due to the inclined extension of the first inclined portion 222 and the second inclined portion 224, the principal planes of the first protrusion 221, the first connecting portion 223, and the second protrusion 225 are not on the same horizontal line. Along the height direction of the lock head 21 (that is, the thickness direction of the connecting rod 10), the second protrusion 225 is the highest (closest to the connecting rod 10), followed by the first connecting portion 223, and the first protrusion 221 is the lowest (farthest from the connecting rod 10).

[0037] In some embodiments, such as Figure 1 As shown, the second locking mechanism 30 also includes a second fastener 32. The second fastener 32 is used to fix the second locking tongue 31 to the connecting rod 10, and the second fastener 32 may be, but is not limited to, a rivet.

[0038] In some embodiments, such as Figure 3 As shown, the second latch 31 includes a second connecting portion 311, a third connecting portion 312, and a third protrusion 313 connected in sequence. The second connecting portion 311 is fixed to the connecting rod 10 by a second fastener 32, thereby fixing the second latch 31 as a whole to the connecting rod 10. The second connecting portion 311 may be in the form of a thin sheet, and its main plane (the surface perpendicular to the thickness direction, i.e.) Figure 3 The upper or lower surface of the second connecting part 311 can be connected to the main plane of the connecting rod 10 (the surface perpendicular to the thickness direction, i.e.) Figure 1 The upper or lower surface of the connecting rod 10 is parallel to it. The third connecting part 312 is connected to one end of the second connecting part 311 and extends in a direction away from the connecting rod 10 (that is, along...). Figure 3The third connecting portion 312 (extending downwards) may be substantially perpendicular to the connecting rod 10 or the second connecting portion 311. The third protrusion 313 is connected to the end of the third connecting portion 312 away from the second connecting portion 311 (or the connecting rod 10) and protrudes from the surface of the third connecting portion 312 in a direction away from the first locking mechanism 20. The third protrusion 313 is used to insert into or extend out of the object to be locked, thereby achieving locking or unlocking.

[0039] Furthermore, such as Figure 3 As shown, the cross-sections of the second connecting portion 311 and the third connecting portion 312 can be “7” shaped, and the cross-sections of the third connecting portion 312 and the third protrusion 313 can be “L” shaped.

[0040] In some embodiments, such as Figure 4 As shown, the bidirectional linkage lock 100 has a locked state, and the lock head 21 can be rotated to switch the bidirectional linkage lock 100 to the locked state. For example, the lock head 21 can be rotated counterclockwise, and the first bolt 22 will rotate with the lock head 21. The rotation of the first bolt 22 will drive the connecting rod 10 to move away from the lock head 21 along its extension direction (that is, the connecting rod 10 moves downward to...). Figure 4 (as shown in the diagram), thereby causing the first protrusion 221 of the first latch 22 and the third protrusion 313 of the second latch 31 to extend into the object to be locked, thereby causing the bidirectional linkage lock 100 to switch to the locked state.

[0041] Furthermore, when the bidirectional linkage lock 100 is in the locked state, the main plane of the first protrusion 221 is parallel to the main plane of the connecting rod 10, the first fastener 41 of the limiting mechanism 40 can contact the arc-shaped end of the opening 110 that is closer to the lock head 21, and the second latch 31 is furthest from the lock head 21.

[0042] In some embodiments, such as Figure 5 As shown, the two-way interlocking lock 100 also has an unlocked state, which can be switched to by rotating the lock head 21. For example, the lock head 21 can be rotated clockwise, and the first bolt 22 will rotate with the lock head 21. The rotation of the first bolt 22 will drive the connecting rod 10 to move closer to the lock head 21 along its extension direction (that is, the connecting rod 10 moves upward to...). Figure 5 (as shown in the diagram), thereby causing the first protrusion 221 of the first latch 22 and the third protrusion 313 of the second latch 31 to extend from the locked object, thereby causing the bidirectional linkage lock 100 to switch to the unlocked state.

[0043] Furthermore, when the bidirectional linkage lock 100 is in the unlocked state, the main plane of the first protrusion 221 is approximately perpendicular to the main plane of the connecting rod 10, and the first fastener 41 of the limiting mechanism 40 can contact the arc-shaped end of the opening 110 that is closer to the second latch 31, and the second latch 31 is closest to the lock head 21.

[0044] The bidirectional linkage lock 100 provided in this application embodiment is configured with a connecting rod 10 movably connected to the first locking tongue 22 (the connecting rod 10 is movably connected to the first locking tongue 22 via a slide groove 220 and a connecting pin 11), and a second locking tongue 31 is provided on the connecting rod 10. This allows the rotation of the first locking tongue 22 to drive the connecting rod 10 to move, and the movement of the connecting rod 10 to drive the second locking tongue 31 to move. This allows one lock head 21 to simultaneously control the movement of the first locking tongue 22 and the second locking tongue 31, thereby enabling multiple points to be locked or unlocked simultaneously. This simplifies operation and improves the efficiency of locking or unlocking.

[0045] The above description describes some specific embodiments of this application, but in actual applications, the application should not be limited to these embodiments. For those skilled in the art, other modifications and alterations made based on the technical concept of this application should fall within the protection scope of this application.
