Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to an electronic lock handle reversing mechanism. Background Technology

[0002] In short, a lock is a security device that uses physical or electromechanical means to reliably secure two objects (usually doors, windows, containers, etc.) together and prevent unauthorized opening or separation. Electronic locks are an intelligent upgrade of mechanical locks; they use electronic circuits and control modules to manage key authentication, but the final locking action is still typically performed by mechanical components.

[0003] However, due to different door opening directions, the handle installation direction also varies. To achieve universal compatibility across different door opening directions, some electronic locks on the market are designed with reversing mechanisms. However, these reversing mechanisms are overly complex. When reversing the handle, the entire lock needs to be disassembled, and the connection direction and position of the handle and signal wires need to be adjusted. Since the signal wires are coiled inside the lock, they are easily crushed or scratched during disassembly and assembly. At the same time, for ordinary users, due to a lack of professional knowledge and skills, other lock components are easily damaged or lost during disassembly and assembly, or components may not be installed properly, causing the lock to malfunction and requiring repeated disassembly and repair. This makes the reversing mechanism cumbersome and inefficient to operate, and may also affect the original function of the lock. Therefore, improvements are urgently needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an electronic lock handle reversing mechanism that is convenient, simple to operate, and has high reversing efficiency.

[0005] To solve the above technical problems, the present invention can be implemented using the following technical solutions: An electronic lock handle reversing mechanism includes a cover, a rotating module, a positioning module, and a handle. The rotating module and the positioning module are respectively mounted on the cover, with the positioning module located above the rotating module. The handle is connected to the rotating module. The cover has a first fixing post and a second fixing post, located on the left and right sides of the rotating module, respectively. The rotating module has a fixing ear and a reversing positioning slot. The fixing ear engages with the first and second fixing posts, respectively. There are two sets of reversing positioning slots, symmetrically arranged, and each set engages with the positioning module. When the handle faces right, the fixing ear corresponds to the first fixing post, and the positioning module corresponds to one set of reversing positioning slots. When the handle faces left, the fixing ear corresponds to the second fixing post, and the positioning module corresponds to the other set of reversing positioning slots.

[0006] In one embodiment, the rotating module includes a rotating disk, a reversing disk, and a torsion spring. The rotating disk has a rotating shaft in the middle, which passes through the housing cover. The reversing disk is sleeved on the rotating shaft, and a first bearing is provided between the rotating shaft and the reversing disk. The torsion spring is provided between the rotating disk and the reversing disk and can act on the rotating disk and the reversing disk respectively. The fixing lug and the reversing positioning slot are both provided on the reversing disk.

[0007] In one embodiment, the fixing ear has a fixing hole, which can correspond to the first fixing post and the second fixing post respectively. When the fixing hole corresponds to the first fixing post or the second fixing post, it can be fixed by the reversing fastener.

[0008] In one embodiment, the side of the turntable opposite the reversing disk is provided with two sets of first limiting walls, and the side of the reversing disk opposite the turntable is provided with a second limiting wall corresponding to the first limiting walls. The two ends of the torsion spring abut against the first limiting wall and the second limiting wall respectively.

[0009] In one embodiment, the steering wheel is provided with two sets of limiting grooves, and the two sets of limiting grooves are symmetrically arranged. Two positioning holes are provided on the rotating disk, and the two positioning holes correspond to the two sets of limiting grooves respectively.

[0010] In one embodiment, the positioning module includes a positioning box, a reversing positioning paddle, and a spring. The positioning box is fixedly installed on the cover and has a toggle groove inside. The reversing positioning paddle and the spring are respectively installed in the toggle groove, and the bottom end of the reversing positioning paddle extends outward to form a positioning block. The positioning block can switch with two sets of reversing positioning grooves respectively. The two ends of the spring abut against the top end of the reversing positioning paddle and the inner wall of the toggle groove respectively.

[0011] In one embodiment, the positioning box has a movable hole on its face wall, and the movable hole corresponds to the toggle slot. The reversing positioning paddle is located at one end of the toggle slot and has a toggle block bent thereon. The toggle block extends outward from the movable hole.

[0012] In one embodiment, a second bearing is provided between the rotating shaft and the housing cover.

[0013] In one embodiment, the handle is connected to the pivot via a fastener. Beneficial effects

[0014] This utility model relates to an electronic lock handle reversing mechanism. A first and second fixed post are provided on the housing cover, and a fixed ear and two sets of reversing positioning slots are provided on the rotating module. The fixed ear engages with the first and second fixed posts respectively, and the two sets of reversing positioning slots engage with the positioning module. The handle is connected to the rotating module. When the handle is facing right, the fixed ear engages with the first fixed post for fixation, and the positioning module positions one set of reversing positioning slots. When a 180° reversal of the handle is required, the fixed ear separates from the first fixed post, and the fixed ear engages with the positioning module. When the positioning module separates from the corresponding reversing positioning slot, the handle is then rotated 180°, and the rotating module rotates 180° accordingly, so that the fixing ear aligns with the second fixing post and the positioning module aligns with another set of reversing positioning slots, making the handle face to the left. This completes the reversing operation of the handle. Moreover, when reversing, it is only necessary to separate the fixing ear from the first or second fixing post and the positioning module from the corresponding reversing positioning slot, without disassembling the entire handle. This makes the handle reversing operation convenient and simple, and can improve the reversing efficiency of the handle. Attached Figure Description

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Please see Figures 1 to 11An electronic lock handle reversing mechanism includes a cover 100, a rotating module 200, a positioning module 300, and a handle 400. The rotating module 200 and the positioning module 300 are respectively mounted on the cover 100, with the positioning module 300 located on the upper side of the rotating module 200. The handle 400 is connected to the rotating module 200. The cover 100 has a first fixing post 110 and a second fixing post 120, which are respectively located on the left and right sides of the rotating module 200. The rotating module 200 has a fixing lug 210 and a reversing mechanism. The positioning slot 220 and the fixing ear 210 respectively switch with the first fixing post 110 and the second fixing post 120. There are two sets of reversing positioning slots 220, which are symmetrically arranged and switch with the positioning module 300 respectively. When the handle 400 is facing right, the fixing ear 210 corresponds to the first fixing post 110, and the positioning module 300 corresponds to one set of reversing positioning slots 220. When the handle 400 is facing left, the fixing ear 210 corresponds to the second fixing post 120, and the positioning module 300 corresponds to the other set of reversing positioning slots 220.

[0021] Specifically, in this embodiment, the rotation module 200 and the positioning module 300 are respectively installed on the inner side of the cover 100, and a first fixing post 110 and a second fixing post 120 are provided on the inner side of the cover 100. The first fixing post 110 and the second fixing post 120 are respectively located on the left and right sides of the rotation module 200, and the positioning module 300 is located on the upper side of the rotation module 200. At the same time, the rotation module 200 is provided with a fixing ear 210 and two sets of reversing positioning slots 220. The fixing ear 210 can switch with the first fixing post 110 and the second fixing post 120 respectively, and the two sets of reversing positioning slots 220 can switch with the positioning module 300 respectively. The handle 400 is connected to the rotation module 200. When the handle 400 is facing to the right, the fixing ear 210 of the rotation module 200 will correspond to and be fixed with the first fixing post 110, and the positioning module 300 will position one set of reversing positioning slots 220. When it is necessary to reverse the direction of the handle 400, the positioning module 300 will be positioned accordingly. When the handle 400 is rotated 180°, the fixed ear 210 is separated from the first fixed post 110, and the positioning module 300 is separated from the corresponding reversing positioning slot 220. Then the handle 400 is rotated 180°, and the rotating module 200 is also rotated 180° when the handle 400 is rotated. When the rotating module 200 is rotated into position, the fixed ear 210 will correspond to and be fixed with the second fixed post 120. The positioning module 300 will position the other set of reversing positioning slots 220, so that the handle 400 faces to the left, thereby realizing the reversing operation of the handle 400. When the handle 400 is reversed, it is only necessary to separate the fixed ear 210 from the first fixed post 110 or the second fixed post 120 and separate the positioning module 300 from the corresponding reversing positioning slot 220 to realize the left and right reversing of the handle 400. There is no need to disassemble the handle 400 as a whole, so the reversing operation of the handle 400 is convenient and simple, and the reversing efficiency of the handle 400 can be improved.

[0022] Of course, in order to enable the fixing ear 210 to cooperate and fix with the first fixing post 110 and the second fixing post 120 respectively, a fixing hole 211 is provided on the fixing ear 210 in this embodiment. When the rotating module 200 rotates, the fixing hole 210 can correspond to the first fixing post 110 or the second fixing post 120 respectively. After the correspondence, the fixing ear 210 can be locked with the first fixing post 110 or the second fixing post 120 by inserting the reversing fastener through the fixing hole 211 (threaded connection). The fixing ear 210 can be used as a screw or bolt, etc., and is not limited here. When reversing is required, the fixing ear 210 can be separated from the first fixing post 110 or the second fixing post 120 simply by unscrewing the reversing fastener from the fixing hole 211, so as to facilitate the reversing operation.

[0023] Please see Figure 3 , Figures 5 to 9 In order for the rotating module 200 to rotate normally, the rotating module 200 in this embodiment includes a rotating disk 230, a reversing disk 240 and a torsion spring 250. The rotating disk 230 has a rotating shaft 260 in the middle, which passes through the cover 100. The reversing disk 240 is sleeved on the rotating shaft 260, and a first bearing 270 is provided between the rotating shaft 260 and the reversing disk 240. The torsion spring 250 is provided between the rotating disk 230 and the reversing disk 240 and can act on the rotating disk 230 and the reversing disk 240 respectively. The fixing ear 210 and the reversing positioning slot 220 are both provided on the reversing disk 240. The handle 400 is connected to the rotating shaft 260 through the fixing member 420.

[0024] By providing an axially extending shaft 260 in the middle of the rotating disk 230, the rotating module 200 can be installed on the cover 100. After installation, the handle 400 can be connected to the shaft 260 by a fastener 420, which can be made of screws for easy connection and fixation. This allows the handle 400 to rotate along with the rotating module 200. In order to ensure that the rotating module 200 and the handle 400 can rotate smoothly, a second bearing 410 is provided between the shaft 260 and the cover 100. The second bearing 410 makes the rotation of the rotating module 200 and the handle 400 smoother.

[0025] In addition, the reversing disc 240 is sleeved on the rotating shaft 260, and a first bearing 270 is provided between the reversing disc 240 and the rotating shaft 260. The fixed lug 210 and two sets of reversing positioning slots 220 are respectively provided on the reversing disc 240. Two sets of first limiting walls 231 and two sets of second limiting walls 241 are respectively provided on the opposite surfaces of the rotating disc 230 and the reversing disc 240. The torsion spring 250 is installed between the rotating disc 230 and the reversing disc 240, and the two ends of the torsion spring 250 abut against the first limiting wall 231 and the second limiting wall 241 at the same time.

[0026] This configuration allows the rotating disk 230 and the reversing disk 240 to form a single unit. Therefore, when the handle 400 rotates, the two ends of the torsion spring 250 act simultaneously on the first limiting wall 231 and the second limiting wall 241, causing the rotating disk 230 and the reversing disk 240 to rotate simultaneously. This allows the fixing ears 210 on the reversing disk 240 to correspond to the first fixing post 110 or the second fixing post 120, and the two sets of reversing positioning slots 220 to switch to the positioning module 3. 00, thereby realizing the reversing operation; after the orientation of the handle 400 is set, the reversing fastener will fix the reversing disk 240. At this time, when the handle 400 is rotated, the reversing disk 240 will no longer rotate, while the rotating disk 230 will rotate. Combined with the cooperation of the first limiting wall 231 and the torsion spring 250, the handle 400 can rotate and reset normally, realizing the opening of the door lock. The first bearing 270 can make the rotating disk 230 rotate more smoothly.

[0027] Furthermore, to control the opening and closing degree of the handle 400 under normal circumstances, the steering wheel 240 in this embodiment is provided with two sets of limiting grooves 242, which are symmetrically arranged. Simultaneously, two positioning holes 232 are provided on the rotating disk 230, each corresponding to one of the limiting grooves 242. When the handle 400 is oriented correctly and the steering wheel 240 is fixed by the steering fasteners, a screw or bolt can be screwed into one of the positioning holes 232 of the rotating disk 230, with the screw-in end of the screw or bolt placed in the corresponding limiting groove 242 of the steering wheel 240. No screw or bolt needs to be screwed into the other positioning hole 232. At this time, when the handle 400 rotates with the rotating disk 230, the screw or bolt will move within the corresponding limiting groove 242, thereby controlling the rotation angle of the handle 400. Limiting is performed to control the opening and closing degree of the handle 400 under normal circumstances. For example, when the handle 400 is facing to the right, screws or bolts are screwed into the positioning hole 232 on the right side (R) so that its end is placed in the limiting groove 242 on the right side; when the handle 400 is facing to the left, the screws or bolts in the positioning hole 232 on the right side (R) are unscrewed and replaced with the positioning hole 232 on the left side (L). When changing direction, the screws or bolts in the positioning hole 232 must be unscrewed in advance to ensure reasonable reversal and simple operation.

[0028] Please see Figure 10 and Figure 11In order to achieve positioning of the handle 400 when it changes direction, the positioning module 300 in this embodiment includes a positioning box 310, a reversing positioning paddle 320 and a spring 330. The positioning box 310 is fixedly installed on the cover 100 and a toggle groove 311 is provided inside the positioning box 310. The reversing positioning paddle 320 and the spring 330 are respectively installed in the toggle groove 311, and the bottom end of the reversing positioning paddle 320 extends outward to form a positioning block 321. The positioning block 321 can switch and correspond to the two sets of reversing positioning slots 220 respectively. The two ends of the spring 330 abut against the top end of the reversing positioning paddle 320 and the inner wall of the toggle groove 311 respectively.

[0029] When reversing, the reversing positioning paddle 320 in the actuation slot 311 can be moved upwards to compress the spring 330. When the reversing positioning paddle 320 moves upwards, the positioning block 321 at its bottom end will disengage from one of the reversing positioning slots 220 of the rotation module 200. At this time, the handle 400 can be reversed 180°. After the reversing is completed, the other set of reversing positioning slots 220 of the rotation module 200 will correspond to the reversing positioning paddle 320. The reversing positioning paddle 320 will be reset under the action of the spring 330 to insert the positioning block 321 at the bottom end of the reversing positioning paddle 320 into the reversing positioning slot 220, thereby realizing the positioning of the rotation module 200 and positioning the orientation of the handle 400. The cooperation between the reversing positioning paddle 320 and the spring 330 makes the operation of the handle 400 convenient and simple when reversing.

[0030] Furthermore, to facilitate the movement of the reversing positioning paddle 320, a movable hole 312 is provided on the wall of the positioning box 310. This movable hole 312 corresponds to the actuation groove 311. Simultaneously, an actuation block 322 is bent at one end of the reversing positioning paddle 320 located in the actuation groove 311. This actuation block 322 can extend outward from the movable hole 312. The outwardly extending actuation block 322 facilitates the user's movement of the reversing positioning paddle 320, causing it to move upward and separating the positioning block 321 from the reversing positioning groove 220. This makes the reversing operation of the handle 400 simpler and more convenient.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
