Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to an unlocking tool and an unlocking method for a blade lock without a side column. Background Art

[0002] In the field of lock security, blade locks are widely used in high-security scenarios such as safes and vaults due to their complex structure. Traditional blade locks rely on the side column to fit into the blade groove to achieve locking, and the corresponding technical opening tools (such as single hooks and pick tools) are relatively mature. However, with the popularity of blade locks without side columns (using a central shaft or internal retaining spring to replace the side column), traditional tools face serious adaptation difficulties, specifically manifested as:

[0003] (1) The efficiency of a single hook tool is significantly reduced when opening a 5-blade standard 9-blade lock. The operation complexity is greatly increased. It takes an average of 2 minutes and 30 seconds to open a 5-blade standard 9-blade lock, while the time required for a 9-blade lock of the same level increases to more than 6 minutes. This is mainly because the depth difference of the blade grooves of the 9-blade lock is increased, making it difficult for a single hook to sense subtle changes in resistance. In addition, the return of the blades requires the simultaneous alignment of the center axis and the balance of the spring pressure, and the operational tolerance rate is extremely low. When inexperienced people use a single hook to open a 9-blade lock, the probability of blade deformation is as high as 43%, and the lock core scratch rate is 27%.

[0004] (2) The adaptability of tinfoil tools to side-postless blade locks is also significantly reduced. The principle of tinfoil tools relies on plastic material to fill the gap between the blades to form a temporary key tooth shape, but its design is based on the lateral pressure feedback of the side-post lock. In side-postless locks: the vertical force applied to the center axis makes it difficult for tinfoil to form a stable shape. The multi-level arrangement of blades (usually ≥7 pieces) reduces the embossing success rate to below 12%.

[0005] (3) While mainstream two-in-one tools on the market offer adjustable pick angles, their design is still tailored to the lateral locking mechanism of side-post locks. In non-side-post locks, the tool head width cannot accommodate the narrow lock hole. The lack of a central axis synchronous linkage mechanism necessitates manual rotation and step-by-step operation, resulting in low efficiency.

[0006] To address the need for opening pinless locks, some manufacturers have introduced specialized quick-opening tools. However, these tools still present significant challenges: their complex structure makes them difficult to operate, they can easily cause unnecessary damage to the lock cylinder, and their high learning curve limits their widespread adoption. Therefore, existing tools cannot simultaneously meet the requirements for speed, non-destructiveness, and universal applicability in safe emergency opening services. Summary of the Invention

[0007] The present invention aims to address, at least to a certain extent, one of the technical problems encountered in the aforementioned technologies. To this end, the present invention provides a tool and method for unlocking a pinless blade lock. By utilizing bidirectional wave grooves to guide the blades to self-align and trigger their return to their original position, the tool achieves foolproof, quick-opening operation while ensuring non-destructive operation. This method fills a gap in the field of pinless lock opening tools.

[0008] To achieve the above-mentioned object, the present invention provides, in one aspect, a tool for unlocking a blade lock without a side column, comprising:

[0009] spoon handle;

[0010] A key rod is connected to the key handle, and the key rod has a plate body suitable for inserting into the lock hole of the lock cylinder;

[0012] A second wave groove is provided on the lower surface of the plate body along the length direction thereof. The second wave groove has two relatively spaced apart sinusoidal wave side walls along the width direction of the plate body.

[0013] According to an embodiment of the present invention, a locking tool for a side column blade lock is provided. A bidirectional wave groove is designed on the key rod. The wave groove can guide the blade lock to self-align, and then the shaking trigger returns to the position until the blade is unlocked. The operation time is fast, and the rescue or capture efficiency is improved. The waveform parameters of the wave groove can cover a variety of blade lock specifications, avoid hard friction between the tool and the lock core, and can be losslessly compatible. Compared with traditional tools, it has the advantages of high efficiency, non-destructiveness, and easy operation.

[0014] In addition, the unlocking tool for a blade lock without a side column according to the above embodiment of the present invention may also have the following additional technical features:

[0016] Optionally, the key rod is slender and flat, and has a connecting portion connected to the key handle, the width of the connecting portion is greater than the width of the plate body, so as to form a limiting step at the connection position between the plate body and the connecting portion.

[0017] Optionally, the insertion end of the plate body has an arc-shaped guide head.

[0018] Optionally, the spoon handle is further connected to an auxiliary rod, which is arranged along the radial direction of the spoon handle.

[0019] Optionally, auxiliary glue is also included, and the auxiliary glue is suitable for filling into the first wave groove or the second wave groove.

[0020] In another aspect, the present invention provides a method for quickly unlocking a pillarless blade lock, using the above-mentioned pillarless blade lock unlocking tool to perform the unlocking operation, comprising the following steps:

[0021] Insert the plate of the key rod into the lock hole so that the plate passes through the blade gap of the blade lock without a side column;

[0022] Shake the key handle to push the blade to the unlocked position through the first and second wave grooves on the plate body;

[0023] Turn the key handle to rotate the lock cylinder to unlock.

[0024] According to an embodiment of the present invention, a quick unlocking method for a side column blade lock is provided. By designing a bidirectional wave groove on the key rod, the wave groove can guide the blade lock to self-align, and the shaking trigger returns to the blade unlocking, the operation time is fast, and the rescue or capture efficiency is improved; the waveform parameters of the wave groove can cover a variety of blade lock specifications, avoid hard friction between the tool and the lock core, and can be losslessly compatible; it has the advantages of simple operation, fast unlocking speed, and strong applicability.

DETAILED DESCRIPTION

[0031] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0032] In the field of lock security, blade locks are widely used in high-security scenarios such as safes and vaults due to their complex structure. Traditional blade locks rely on the side column to fit into the blade groove to achieve locking, and the corresponding technical opening tools are relatively mature. However, with the popularity of side column-less blade locks, traditional tools face serious adaptation obstacles. Specifically, they are limited in effectiveness of single hook tools, incompatible with tinfoil tools, and incompatible with two-in-one tools. In order to meet the opening needs of side column-less locks, some manufacturers have launched special quick-opening tools, but there are still significant problems: complex structure, damage to the lock core, and high learning threshold. Therefore, in the emergency opening service of safes, existing tools cannot meet the requirements of speed, non-destructiveness, and universality.

[0033] The present application aims to solve the problem of how to adapt to the structural characteristics of the side column blade lock and achieve a fast and lossless unlocking operation.

[0034] like Figures 1 to 3 As shown, an embodiment of the present application discloses a tool for unlocking a blade lock without a side column, comprising a key handle 1 and a key rod 2.

[0035] Specifically, the key rod 2 is connected to the key handle 1 and comprises a plate 21 adapted to be inserted into the lock hole of the lock cylinder. The upper surface of the plate 21 is provided with a first wave-shaped groove 211 along its length, which has two spaced-apart sinusoidal wave sidewalls 211a along its width. The lower surface of the plate 21 is provided with a second wave-shaped groove 212 along its length, which has two spaced-apart sinusoidal wave sidewalls 212a along its width.

[0036] As can be understood, the key handle 1 is intended for gripping, while the key bar 2 is provided with a first wave groove 211 and a second wave groove 212 on the upper and lower surfaces of the plate 21, respectively. These wave grooves have two spaced-apart sinusoidal wave sidewalls 211a and 212a along the width of the plate 21. These designs allow the wave grooves to effectively push the blade to the unlocked position when inserted into the keyhole and shaken, enabling a quick and non-destructive unlocking operation.

[0037] Traditional blade lock tools are primarily designed for the lateral locking mechanism of side-post locks. However, side-postless blade locks utilize a central shaft or internal retaining spring in place of the side post, making traditional tools difficult to adapt. Single-hook tools perform poorly in terms of operational complexity and opening efficiency, tinfoil tools struggle to maintain stable form, and two-in-one tools lack a central shaft synchronization mechanism. These challenges prompted the inventors to consider designing a tool specifically for side-postless blade locks to address these technical issues.

[0038] The side-column-less blade lock unlocking tool proposed in this application is inserted into the lock hole through the plate body 21 on the key rod 2, and uses the wave grooves on the plate body 21 to push the blade to the unlocked position. The sinusoidal wave sidewall design of the first wave groove 211 and the second wave groove 212 enables the tool to better cooperate with the blade during operation, reducing the risk of blade deformation and lock core damage. Specifically, the upper surface of the plate body 21 is provided with a first wave groove 211 having two relatively spaced sinusoidal wave sidewalls; the lower surface of the plate body 21 is provided with a second wave groove 212, also having two relatively spaced sinusoidal wave sidewalls. These wave grooves can effectively push the blade to the unlocked position when inserted into the lock hole and shaken.

[0039] As a preferred embodiment, the crests of the two sinusoidal wave side walls of the first wave groove 211 are staggered or symmetrically distributed; the crests of the two sinusoidal wave side walls of the second wave groove 212 are staggered or symmetrically distributed. By staggering or symmetrically distributing the crests of the two sinusoidal wave side walls of the first wave groove 211 and the second wave groove 212, it is possible to achieve better propulsion of the blade, thereby improving the unlocking efficiency and success rate. Through this design, the crest distribution of the first wave groove 211 and the second wave groove 212 can effectively reduce the friction and jamming of the blade during the unlocking process, allowing the blade to move more smoothly to the unlocked position. In addition, this crest distribution method can also increase the uniformity of the force applied to the blade during the unlocking process, reducing the risk of blade deformation and lock core damage.

[0040] Specifically, the wave crests of the two sinusoidal wave side walls of the first wave trough 211 and the second wave trough 212 can be staggered or symmetrically distributed in a variety of ways. For example, the wave crests can be staggered at predetermined intervals, or they can be symmetrically arranged in relative positions. Specifically, this wave crest distribution can be achieved through precision machining technology to ensure that the position and height of each wave crest meet the design requirements. As a preferred embodiment, CNC machine tools can be used for precision machining to ensure the accuracy and consistency of the wave crests. In addition, mold forming technology can be used to mass-produce wave troughs with the same wave crest distribution characteristics, further improving production efficiency and product consistency.

[0041] As a preferred embodiment, the key rod 2 is elongated and flat, and includes a connecting portion 22 connected to the key handle 1. The width of the connecting portion 22 is greater than the width of the plate 21, forming a stop step at the junction between the plate 21 and the connecting portion 22. The design of the stop step ensures that the plate 21 is effectively restrained when inserted into the keyhole, preventing excessive displacement of the plate 21 during use, thereby improving the stability and efficiency of the lock picking tool. Specifically, the elongated and flat design of the key rod 2 enables smooth insertion into the keyhole, while the width of the connecting portion 22 is greater than the width of the plate 21. The stop step formed at the junction between the plate 21 and the connecting portion 22 acts as a stop, preventing unnecessary movement of the plate 21 during use. The stop step can be implemented by precisely machining the connection between the connecting portion 22 of the key rod 2 and the plate 21, making the width of the connecting portion 22 greater than the width of the plate 21, thereby forming the stop step. In addition, mold forming technology can be used during the manufacturing process to ensure the consistency and reliability of the stop step.

[0042] As a preferred embodiment, the insertion end of the plate body 21 has an arc-shaped guide head 213. The design of the arc-shaped guide head 213 allows the plate body 21 to be inserted into the lock hole more smoothly. The arc-shaped guide head 213 reduces the resistance and friction during the insertion process, ensuring that the plate body 21 can smoothly pass through the edge of the lock hole during insertion and penetrate the blade gap of the edgeless column blade lock. The arc-shaped guide head 213 can be implemented in a variety of ways. For example, the arc-shaped guide head 213 can be directly processed on the insertion end of the plate body 21 by integral molding. In addition, the specific size and curvature of the arc-shaped guide head 213 can be adjusted according to actual application requirements to ensure the best insertion effect and minimum friction.

[0043] As a preferred embodiment, the key handle 1 is further connected to an auxiliary rod 3, which is arranged along the radial direction of the key handle 1. The auxiliary rod 3 provides additional operational support during the unlocking process, allowing the user to better grasp and operate the unlocking tool. This design improves the operational stability and efficiency of the unlocking tool by increasing the operational support points of the key handle 1, thereby solving the problem of convenience in operating the unlocking tool for a blade lock without a side column. By adding the auxiliary rod 3, the user can apply force more stably during operation, reducing the complexity and error rate of the operation. The shape and size of the auxiliary rod 3 can be adjusted according to the specific design of the key handle 1 to provide optimal operational support. Specifically, the auxiliary rod 3 can be designed into a circular, square or other suitable shape for easy grip and operation. As a preferred embodiment, the auxiliary rod 3 can be set at a position on the key handle 1 close to the key rod 2 to evenly distribute the user's force application points and further improve the stability of the operation.

[0044] As a preferred embodiment, it also includes auxiliary glue, which is suitable for filling into the first wave groove 211 or the second wave groove 212. After filling the wave groove, the auxiliary glue can stabilize the position of the tool in the lock core, increase the adaptability and stability of the unlocking tool, and thus improve the unlocking efficiency and success rate. By filling the auxiliary glue, the tool can better match the internal structure of the lock core, reducing unlocking failures or lock core damage caused by tool incompatibility. The auxiliary glue can be made of different materials, such as silicone, polyurethane glue or other materials with good filling properties. The amount of auxiliary glue should be moderate, so that it can fill the wave groove without overflowing and affecting the operation of other components.

[0045] Furthermore, the present application also proposes a quick unlocking method for a borderless blade lock, which uses any unlocking tool for a borderless blade lock in the present application to perform an unlocking operation, including the following steps: inserting the plate body 21 of the key rod 2 into the lock hole so that the plate body 21 passes through the blade gap of the borderless blade lock; shaking the key handle 1 to push the blade to the unlocking position through the first wave groove 211 and the second wave groove 212 on the plate body 21; rotating the key handle 1 to drive the lock core to rotate to complete the unlocking.

[0046] Using any of the pinless blade lock unlocking tools described in this application, the unlocking operation is performed by utilizing the tool's structural features. The plate 21 of the key rod 2 is inserted into the lock hole, passing through the gap between the blades. The key handle 1 is shaken, using the wave grooves to push the blades to the unlocked position. Finally, the key handle 1 is rotated to rotate the lock cylinder to unlock the lock. This method, through the design of a specific tool and its usage steps, solves the problems of low efficiency, damage to the lock cylinder, and high learning requirements during the unlocking process of pinless blade locks.

[0047] In this application, after the plate 21 of the key shaft 2 is inserted into the keyhole, the blade is moved to the unlocked position by shaking the key handle 1, utilizing the structural features of the first and second wave grooves 211, 212 on the plate 21. Specifically, the first and second wave grooves 211, 212 are arranged along the length of the plate 21 and have sinusoidal sidewalls. Shaking the key handle 1 generates thrust, pushing the blade to move. The shaking of the key handle 1 can be a small up and down motion.

[0048] Furthermore, before shaking the key handle 1 , semi-solid auxiliary glue can be filled into the first wave groove 211 or the second wave groove 212 so that the auxiliary glue is flush with the top surface of the wave groove, thereby improving the stability and success rate of unlocking.
