Description

Automatically modified mechanical code lock and shared umbrella during unlocking

Technical field

The invention relates to the technical field of password locks, in particular to a mechanical code lock and a shared umbrella which are automatically modified during unlocking.

Background technique

The sharing economy has recently been hotly debated by the Internet, called sharing, or leasing economy; among them, the main mode of sharing umbrellas is based on the self-service rental equipment of umbrellas, and the borrowing points of umbrella equipment are laid in the city. The pattern is similar to sharing a bicycle. The rental management of the shared umbrella is carried out in a password lock mode similar to that of a shared bicycle. The password of the shared umbrella is obtained by scanning the code, and the input is correct and can be accessed.

The types of password locks are mechanical and electronic. Among them, the electronic password lock has better security in use, and the unlocked dynamic password is obtained after scanning the code by the mobile phone, thereby unlocking, and the use of the shared umbrella can be ensured under relatively safe management. However, the shortage of electronic password latching requires the regular replacement of the battery, the waterproof protection of the whole circuit device, the pollution of the battery to the environment, and the high cost. In the city with a large amount of shared umbrellas, each umbrella is carried out. Regular replacement of the battery is greatly inconvenient and difficult to perform. Another type of mechanical code lock is relatively simple to maintain, so it has a better prospect of use; however, since the password of the lock cylinder is unlocked from the original factory setting, the password cannot be changed in subsequent use. This has caused many users to remember or inform others after using the password, so that the use of the subsequent shared umbrella becomes unpaid for sharing, which is not conducive to the operation of the product.

Summary of the invention

The main object of the present invention is to provide a mechanical code lock that is automatically modified during the unlocking process, and aims to enable the main body of the sharing economy to automatically change the original password after use, thereby improving the security of the product.

In order to achieve the above object, the mechanically-locked lock which is automatically modified in the unlocking process of the present invention includes a lock cylinder, the lock cylinder includes an axially reciprocable movable shaft, and a code wheel assembly sleeved on the movable shaft;

The code wheel assembly includes a driving pulley and a reversing wheel sleeved on the moving shaft, and a code wheel sleeved on the driving pulley; wherein

The inner surface of the code wheel has a first groove and a first protrusion spaced apart in a radial direction, and the first protrusion is provided with a first guiding slope;

The reversing wheel is provided with a contact piece having a second guiding bevel surface adapted to the first guiding bevel;

The driving pulley is sleeved with the code wheel by a second groove and a second protrusion which are spaced apart on the outer surface; and the driving pulley is further provided with a top tooth for abutting the second guiding slope.

On the basis of the above mechanical code lock, the present invention also proposes a shared umbrella product having the above mechanical code lock.

The mechanical code lock which is automatically changed in the unlocking process of the invention can be combined with the existing mechanical type lock by the combination of the driving pulley and the reversing wheel, and can be unlocked by the moving shaft. The password correspondence of the wheel generates a misplaced change, thereby realizing the effect of automatically changing the password; and the regularity and numerical difference of the password replacement each time is related to the rotation angle of the reversing wheel, and the rotation angle can be manually unlocked by the push button The sliding stroke is designed and controlled with the bevel angle of the second guiding bevel, so that the password after the change has a predictable law and relationship with the original password. Then, for the new user to use the next time, the new password can be notified to the new user by scanning the code, so in the process of using, it can solve the security that the user remembers or informs others after knowing the original password. Sexual problems can also avoid many defects such as the regular replacement of the power supply of the electronic dynamic combination lock.

Detailed ways

The implementation, functional features and advantages of the present invention will be further described in conjunction with the drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention provides a mechanical code lock which is automatically modified during the unlocking process, and its structure is shown in Figure 1-12. In this embodiment, a shared umbrella is used as a design and use example of a mechanically-locked lock that is automatically modified during unlocking. Referring first to FIG. 1-2, FIG. 1 is a schematic structural view of a shared umbrella with an automatically modified mechanical combination lock. 2 is a schematic structural view of the casing of FIG. 1 after opening; from FIG. 1-2, the combination lock of the present invention includes a casing 10 and a lock cylinder 20 installed in the casing 10; the casing 10 is used in the present invention. To accommodate the base parts that are fixed and assembled with the structure of the lock cylinder 20.

Typically, based on the design and ease of use of the shared umbrella product, the combination lock is mounted on the umbrella handle of the umbrella, so that it can be seen from Figure 2 of the present invention that the outer casing 10 is directly on the umbrella handle portion. It is further processed to have the function of the outer casing 10. Based on the convenience of use, the outer casing 10 of the present embodiment is composed of both the face shell 11 and the bottom case 12, which can improve the convenience of production assembly and subsequent maintenance and replacement. Both the face shell 11 and the bottom case 12 can be fixedly connected by a detachable manner such as a screw/snap, and the inside of the case 11 and the bottom case 12 form a receiving cavity for assembling the structure of the lock cylinder 20. Of course, if the above-mentioned automatically modified mechanical combination lock extension extension of the present invention is applied to other shared products (such as sharing bicycles), the outer casing 10 can be appropriately selected to be combined or designed by itself, and is not limited. In the drawings of the present invention, the design of the umbrella handle is exemplified.

Referring further to FIG. 3, the mechanically-locked lock is automatically modified during the unlocking process of the present invention, and the lock cylinder 20 structure includes a movable shaft 21 disposed along the axial direction of the outer casing 10 and telescopically movable in the axial direction, the movable shaft 21 is connected with a manual unlocking push button 30 disposed on the umbrella handle of the umbrella, and the movable shaft 21 is moved in the axial direction by the manual unlocking push button 30, thereby making the unlocking structure and the manual unlocking push button. 30 Both can produce a bond. From Fig. 1, the manual unlocking push button 30 is mounted in a sliding groove disposed axially on the outer casing 10 and is slidable in the sliding groove. The human hand grasps the expansion and contraction of the movable shaft 21 by pressing and holding the manual unlocking push button 30 to realize the unlocking. In this embodiment, the umbrella can be opened by unlocking.

Referring further to FIGS. 3-8, the character wheel assembly 22 is mounted side by side on the moving shaft 21, and the code wheel assembly 22 includes a driving pulley 221 and a reversing wheel 222 sleeved on the moving shaft 21, and is sleeved on The code wheel 223 outside the pulley 221 is driven. Further, in order to ensure the opening and closing of the lock lock structure, an unlocking blocking protrusion 121 (FIG. 5) is disposed on the outer casing 10, and a notch groove 2223 corresponding to the unlocking blocking protrusion 121 is disposed on the reverse rotating wheel 222 ( As shown in FIG. 8 , when the code wheel assembly 22 is rotated to a position where the unlocking blocking protrusion 121 is opposite to the notch groove 2223, the manual unlocking push button 30 drives the moving shaft 21 to drive the driving pulley 221 of the code wheel assembly 22 and change. The rotation wheel 222 (the code wheel 223 is embedded in the outer casing 10 and cannot move along with the axial direction) moves along the axial direction of the outer casing 10. At this time, the unlocking blocking block 121 and the notch groove 2223 are opposite each other, and the combination of the combination wheel assembly 22 is not It will be blocked by the unlocking block 121, so unlocking can be achieved.

In order to ensure that the function of the lock core code is automatically changed during the unlocking process, the structure design of the code wheel assembly 22 is further modified. For details, refer to FIG. 6-8. The inner surface of the code wheel 223 is provided with a radial direction. The inner groove 2231 and the inner boss 2232 which are arranged in the direction are disposed on the outer surface of the driving pulley 221 to provide an outer groove 2211 and an outer boss which are matched with the inner groove 2231 and the inner boss 2232 which are disposed between the above-mentioned phases. 2212. The code wheel 223 is sleeved on the drive pulley 221 by the concave-convex engagement, and the drive pulley 221 is slidable in the axial direction within the code wheel 223.

At the same time, one end of the inner boss 2232 on the inner surface of the code wheel 223 facing the direction of the reversing wheel 222 is disposed at the first guiding slope 2233. A contact piece 2221 is disposed on a side of the driving wheel 221 corresponding to the reversing wheel 222. The top of the contact piece 2221 has a second guiding slope 2222 that is engaged with the first guiding slope 2233. Further, the driving pulley 221 is provided with a top tooth 2213 that abuts against the second guiding slope 2222 on the side surface of the reversing wheel 222.

Referring to Figures 9-12, the combined state of the combination wheel assembly 22 and the state in which the reversing wheel 222 is pushed away from the code wheel 223; after the top tooth 2213 is pressed against the second guiding bevel 2222 of the contact piece 2221, manually When the unlocking push button moves the moving shaft 21 in the axial direction in the outer casing 10, the moving shaft 21 drives the driving pulley 221 to further move in the axial direction, thereby pushing the reversing wheel through the abutting second guiding inclined surface 2222. 222 moves toward the direction away from the code wheel 223, and since the top tooth 2213 is pushed against the second guide bevel 2222, the reversing wheel 222 itself will be on the bevel of the second guide bevel 2222 during being pushed. The self-rotation under the action of the decomposition force, of course, the angle of its rotation is related to the distance traveled by the stroke. In the present invention, the angle of the rotation can be controlled by setting the stroke to be pushed. When the angle of rotation exceeds the angle of an adjacent inner groove 2231 and the inner boss 2232 of the inner surface of the code wheel 223, then the reversal An angle difference between the second guiding slope 2222 of the runner 222 and the first guiding slope 2221 of the originally fitted code wheel 223 is misaligned, and after the manual thrust is removed, the second guiding ramp 2222 is restored to In combination with the code wheel 223, the combined position at the time of the original unlocking is different, that is, the change position of the unlocking position where the notch groove 2223 is located and the password number of the code wheel 223 are misaligned, according to this The misplaced effect effect automatically changes the password function and effect.

Of course, from the detailed description of the rotation of the above-described reversing wheel 222 during the pushing process and the direction of rotation of the clockwise rotation indicated in FIG. 11, those skilled in the art will be aware of the direction of the rotation and the bevel of the second guiding bevel 2222. The direction is related; if in the implementation of the technology, the technician designs the slope of the second guiding slope 2222 to be opposite to the direction of the slope in FIG. 8 of the embodiment (of course, the first guiding slope 2233 is also reversely designed in this way) Then, the direction of rotation in the process of being pushed will be presented in the opposite counterclockwise rotation in Fig. 11 of the present embodiment. This simple and similar way can be adopted by the technician himself, which is substantially the same as the embodiment.

The mechanical code lock which is automatically modified during the unlocking process of the present invention can be unlocked by the moving shaft 21 by the combination of the driving pulley and the reversing wheel compared with the existing mechanical code lock. Corresponding relationship with the password number of the password wheel produces a misplaced change, thereby realizing the effect of automatically changing the password; and the regularity and numerical difference of the password replacement each time is related to the rotation angle of the reversing wheel, and the rotation angle can be pushed by manual unlocking The sliding stroke of the button 30 is designed and controlled with the bevel angle of the second guiding ramp, so that the password after the change has a predictable law and relationship with the original password. Then, for the new user to use the next time, the new password can be notified to the new user by scanning the code, so in the process of using, it can solve the security that the user remembers or informs others after knowing the original password. Sexual problems can also avoid many defects such as the regular replacement of the power supply of the electronic dynamic combination lock.

Of course, in order to further ensure the stability and convenience of the structural installation of the lock cylinder 20, referring to FIG. 3 and FIG. 13, the lock cylinder 20 further includes a base 24 for assisting the assembly of the above components, and the base 24 is provided with a code wheel assembly. 22 adapted PIN wheel assembly mounting bit 242. Through the base 24, all the parts of the lock cylinder 20 can be assembled into a single complete module for subsequent product assembly and maintenance, without the need to assemble and disassemble each individual component on the bottom case 12. And overhaul; make the product more convenient.

In order to ensure that the lock cylinder can be restored to the combined state after the manual lock is unlocked, referring further to FIG. 3-4, the combination wheel assembly 22 further includes a limit stop 224 disposed opposite the reverse rotation wheel 222, and is sleeved on the movement. A first return spring 225 on the shaft 21, the two ends of the first return spring 225 are respectively connected to the limit stop 224 and the reverse runner 222. When the manual unlocking push button 30 drives the driving pulley 221 to unlock, the first return spring 225 is compressed, and when the manual unlocking push button 30 is released, the first returning spring 225 will rebound and the reversing rotating wheel 222 will be re-engaged. The code wheel 223 is tightly coupled.

At the same time, it can be further seen from the drawing that the limiting baffle 224 is provided with a through hole through which the driving shaft 21 penetrates, and the through hole can be used to ensure that the expansion and contraction of the moving shaft 21 is not affected during use.

Similarly, based on a relatively similar situation, as shown in FIGS. 10 and 12, a second return spring 226 for resetting the drive pulley 221 may be sleeved on the movable shaft 21 between the drive pulley 221 and the reverse runner 222. . The second return spring 226 can be seen from FIG. 10, and the installation manner can be installed inside the driving pulley 221, and of course, it is sleeved on the moving shaft 21, and the two ends are respectively offset from the driving pulley 221 and the reversing rotor 222. hold.

At the same time, after the above two return springs, in order to further ensure that the external force of the movable shaft 21 itself is canceled, the self-reset is self-reset; as can also be seen from FIG. 3, the movable shaft 21 is also sleeved for the movable shaft 21 The reset moving shaft return spring 211, the detailed arrangement of the moving shaft return spring 211 can be seen in FIG. 3, an end piece 213 is disposed on the end of the moving shaft 21, and is also mounted on the base 24 with respect to the end piece 213. There is a spring fixing piece 212, and both ends of the moving shaft return spring 211 are abutted/connected to the spring fixing piece 212 and the end piece 213, respectively.

Then, after the external force on the push button 30 disappears, the first return spring 225 / the second return spring 226 / the moving shaft return spring 211 respectively reset the respective components of the axial movement, thereby ensuring a more stable and accurate overall reset.

Of course, from the drawings of the present invention and the description of the above-described implementation process, the contact piece 2221 needs to be able to cooperate with both the code wheel 223 and the drive pulley 221; in the normal engagement state, it is coupled with the first guide slope 2233 in the password. On the wheel 223; at the same time it also needs to meet the top teeth 2213 that can be driven by the drive pulley 221. Therefore, the technician can use the contact piece 2221 of a suitable thickness to achieve the above requirements.

The design of the cryptographic wheel assembly 22 of the above detailed structure, in each process of unlocking, the reversing wheel 222 will automatically rotate a certain angle, causing the notch groove 2223 thereon to have an angle with respect to the original password number. Displacement, so the password changes itself on the next use.

At the same time, in order to facilitate the stability of the password rotation input of the code wheel 223, a U-shaped guide groove 2234 is arranged between the numbers on the outer surface of the code wheel 223. On the one hand, in order to facilitate the identification and identification of the password number in the use process, on the other hand, It is also to assist the angle of rotation of the code wheel 223 to the input password position. Corresponding to the U-shaped guide groove 2234, the code wheel mounting position 242 is provided with a coded positive position spring block 241 for matching positioning. When the code wheel 223 rotates a number, the coded positive position spring block 241 automatically elastically snaps into the U-shaped. In the guiding groove 2234, when the guiding is in place, there is a feeling of "嗒"; and when it is necessary to continue to rotate the password wheel for password number replacement, it is necessary to force the rotation, so that the password wheel 223 can be guaranteed to enter each password number. The position is relatively stable and does not arbitrarily shift.
