Description

Technical Field

[0001] This utility model relates to the field of locks, and in particular to a transfer connection control device that can empower traditional mechanical locks. Background Technology

[0002] Traditional mechanical locks mostly use mechanical unlocking methods, with a purely mechanical internal structure. Compared to existing electronic locks, the only unlocking methods are external keys and internal buttons, which are inconvenient to use and outdated. However, the global economic downturn in recent years has led to a surge in the prices of various daily necessities, including electronic locks. Therefore, even if customers may recognize the advantages of electronic locks, it is indeed a difficult task to get them to replace their trusted mechanical locks with very expensive electronic locks.

[0003] However, if an additional intermediary control device can be used to enable customers to upgrade traditional mechanical locks with intelligent capabilities without replacing the lock itself, and at a lower cost compared to replacing it with an electronic lock, thus giving it electronic unlocking functionality, there would undoubtedly be a larger market for upgrading and retrofitting existing mechanical locks compared to the current electronic lock market, which is shrinking in the short term.

[0037] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0038] Reference Figures 1 to 9 An embodiment of the transfer connection control device of this utility model, which enables traditional mechanical locks, is proposed:

[0039] A transfer connection control device that enables traditional mechanical locks includes a device body 1, a first connector 2, a second connector 3, and a rear fixing bracket 4. In this embodiment, the first connector 2 and the second connector 3 are chains.

[0040] The rear fixed bracket 4 includes a fixed bracket body 41, a threaded adjusting rod 42, and a nut 43. The fixed bracket body 41 is fixedly connected to the door or door frame.

By adjusting the relative position of the threaded adjusting rod 421 and the fixed bracket body 41, the actual use needs of the user can be met.

[0041] The device body 1 includes a body housing 11, a connecting rod 12, a push switch 13, a first reset spring 16, a second reset spring 17, a limiting rod 15, and an electromagnetic unlocking device 14. The body housing 11 includes a body base 111 and a body top cover 112, which is fixedly connected to the body base 111 by screws. The front and rear sides of the body base 111 are respectively provided with a first through hole and a second through hole, and the inner side of the body base 111 is provided with a body connecting block 116. The bottom inner side of the body base 111 is provided with a first fixing rod 113, a second fixing rod 114, and a third fixing rod 115, wherein one end of the limiting rod 15 is rotatably connected to the first fixing rod 113, and the limiting rod 15 is also provided with a first torsion spring that can drive the limiting rod 15 to reset. The first torsion spring 151 is wound around the first fixed rod 113, and one end of the first torsion spring is pressed on the inner side wall of the main body base, and the other end of the first torsion spring is wound into the first torsion spring connecting groove and is locked on the limiting rod through the first torsion spring connecting groove.

[0042] The connecting rod 12 includes a first connecting rod 121, a second connecting rod 122, and a fixing limiting member 123. The first connecting rod 121 is bent laterally from its rear side to form a first connecting rod limiting seat 1211, and a first connecting rod through hole 1212 is provided in the first connecting rod limiting seat 1211. The second connecting rod 122 is bent laterally from its rear side to form a second connecting rod limiting seat 1221, and a second connecting rod through hole 1222 is provided in the second connecting rod limiting seat 1221. The front side of the first connecting rod 121 passes through the second connecting rod through hole 1222 and extends out from the first through hole of the housing. The front side of the second connecting rod 122 passes through the first connecting rod through hole 1212 and extends out from the second through hole of the housing. The front end of the first connecting rod 121 is connected to the toggle unlocking switch 51 of the mechanical lock 5 through the first connecting member 2. The fixed limiting member 123 is fixedly connected to the first connecting rod 121 by screw connection and is located on the rear side of the second connecting rod limiting seat 1221. The fixed limiting member 123 is provided with a limiting member connecting rod 124 that is adapted to the limiting rod 15.

[0043] The first return spring 16 is disposed on the outer side of the first connecting rod 121 and the second connecting rod 122, between the first connecting rod limiting seat 1211 and the second connecting rod limiting seat 1221. A first connecting rod connecting block 1213 is disposed on the side of the first connecting rod limiting seat 1211, and the two ends of the second return spring 17 are respectively connected to the housing connecting block 116 and the first connecting rod connecting block 1213.

[0044] The electromagnetic unlocking device 14 includes a connecting terminal 142, an electromagnet 141, and a stop lever 143. One end of the stop lever 143 is rotatably connected to a second fixed rod 114. A second torsion spring is also provided on the stop lever 143 to drive it to reset. A stop lever limit block is provided on the stop lever 143. The stop lever limit block and the third fixed rod 115 can limit the limit rod 15. The electromagnet 141 is located on the rear side of the stop lever 143. The movement of the stop lever 143 driven by the electromagnet 141 can release the limit on the limit rod 15. A push switch 13 is provided on the upper cover 112 of the main body. A push switch press block 131 is provided at the bottom of the push switch 13. Pressing the push switch 13 can drive the stop lever 143 to rotate through the push switch press block 131, thereby releasing the limit on the limit rod 15. The electromagnet 141 is connected to an external smart unlocking device via a connection terminal 142. The smart unlocking device can control the operating state of the electromagnet 141. The smart unlocking device can be a button unlocking device, a fingerprint unlocking device, a camera unlocking device, or an iris unlocking device, etc.

[0045] During installation, the fixing limiter 123 on the first connecting rod 121 is engaged with the limiter rod 15, and at this time, the limiter rod 15 is engaged between the stop rod 143 and the third fixing rod 115. The first connecting rod 2 is then straightened and tightened. Then, the position of the second connecting rod limiter 1221 relative to the first connecting rod limiter 1211 is adjusted to compress the first return spring 16, so that the compression force of the first return spring 16 is sufficient to cause the first connecting rod 121 to pull and activate the unlocking switch 51 to unlock. At this time, the second return spring 17 is stretched, forming a certain tension.

[0046] When unlocking, the lever 143 can release the lock on the limit lever 15 by unlocking via electromagnet 141 or by pressing switch 13. At this time, under the action of the first return spring 16, the first connecting rod 121 moves backward, thereby driving the toggle unlocking switch 51 to move backward to unlock.

[0047] After the door is opened, it rotates relative to the door frame, reducing the straight-line distance between the front of the second connecting rod 122 and the rear fixed bracket 51. The force exerted on the first connecting rod limiting seat 1211 by the first return spring 16 by the second connecting rod limiting seat 1221 decreases. At this time, under the action of the second return spring 17, the first connecting rod 121 moves towards the mechanical lock 5. Simultaneously, the limiting rod 15, under the action of the first torsion spring 151, presses against the stop rod 143 through the inclined surface on one side of the stop rod limiting block, thus entering between the stop rod limiting block and the third fixed rod 115. The limiting rod 15 again limits the first connecting rod 121, achieving the function of reset and locking.

[0048] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
