Description

Technical Field

[0001] The present application relates to the technical field of door locks, and in particular to door locks, locksets and anti-theft doors. Background Art

[0002] In today's highly electronic world, smart door locks still use mechanical keys to ensure safe unlocking, preventing users from being unable to unlock the door due to electronic function failure. However, this also gives thieves the opportunity to unlock the door through the mechanical keyhole and commit theft.

[0003] In daily life, it is common to set the keyhole on the front of the door lock. In the first case, the keyhole is set on the lock core, and the keyhole is exposed on the outside of the smart lock panel, which is convenient for opening with a key, but at the same time, thieves can easily find the keyhole to unlock and steal. In the second case, the keyhole is covered by a keyhole cover. The keyhole cover can prevent dust or debris from entering and blocking the keyhole, but thieves can still easily find the keyhole cover and open the keyhole to steal. The keyhole cover only blocks the keyhole and does not hide the keyhole. The anti-theft effect is poor, and thieves can easily find the keyhole to unlock. In another case, the keyhole is set at the bottom of the smart lock, but this method still makes it easier for thieves to find the keyhole and unlock. Utility Model Content

[0004] In view of this, the present application provides a door lock, a lock set and an anti-theft door to solve or improve the problem that the key hole cannot be hidden and the anti-theft effect is poor.

[0006] A lock core is provided with a lock hole;

[0007] The base is provided with a through hole, and the through hole is arranged corresponding to the lock hole;

[0008] The handle is connected to the base and covers the through hole. There is a distance between the handle and the base to form a first gap.

[0009] Beneficial Effects: The base is mounted on the door panel, the keyhole corresponds to the through-hole in the base, and the handle is connected to the base to shield the through-hole, thereby reducing the probability of the keyhole being discovered and lowering the risk of theft. A first gap is formed between the handle and the base, and the through-hole is located within the first gap. When a thief uses a lock-picking tool to open the door, he needs to insert it into the keyhole through the first gap, making it more difficult to open the door and improving the anti-theft effect.

DETAILED DESCRIPTION

[0037] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0038] In daily life, it is common to set the keyhole on the front of the lock. The first case is that a keyhole is set on the lock core, and the keyhole is exposed on the outside of the panel of the smart lock, which is convenient for opening with a key, but at the same time, thieves can easily find the keyhole to unlock and steal. The second case is that the keyhole is covered by a keyhole cover. The keyhole cover can prevent dust or debris from entering and blocking the keyhole, but thieves can still easily find the keyhole cover and open the keyhole to steal. The keyhole cover only blocks the keyhole and does not hide the keyhole. The anti-theft effect is poor, and thieves can easily find the keyhole to unlock, which is not a good anti-theft effect. In another case, the keyhole is set at the bottom of the smart lock for the sake of aesthetics, but this method still allows thieves to find the keyhole and unlock it more easily. In order to solve or improve the problem of poor anti-theft effect of existing door locks, a door lock, a lock and an anti-theft door are provided in the embodiments of the present application.

[0039] The following combination Figures 1 to 13 , describing the embodiments of the present application.

[0040] According to an embodiment of the present application, on the one hand, a door lock is provided, including a lock cylinder 1, a base 2 and a handle 4.

[0041] Specifically, the lock core 1 is used to be installed in the door panel, the base 2 is used to be installed on the door panel, a through hole 3 is provided on the base 2, and the through hole 3 is arranged corresponding to the lock hole 102 of the lock core 1. The handle 4 is connected to the base 2 and covers the through hole 3. There is a distance between the handle 4 and the base 2, forming a first gap 5.

[0042] Base 2 is mounted on the door panel. Lock hole 102 of lock cylinder 1 corresponds to through hole 3 of base 2. Handle 4 is connected to base 2 to block through hole 3, reducing the probability of lock hole 102 being discovered and lowering the risk of theft. A first gap 5 is formed between handle 4 and base 2. Through hole 3 is located within first gap 5. When a thief attempts to open the door using an existing unlocking tool, they need to insert the tool into lock hole 102 through first gap 5, making unlocking more difficult and improving the anti-theft effect.

[0043] The technical solution of the door lock provided in this application can improve the anti-theft effect by hiding the keyhole 102 and increasing the difficulty of unlocking.

[0044] In one embodiment, a connecting piece is further included. A connecting hole 101 is opened on the lock core 1, and the connecting piece passes through the connecting hole 101 to fix the lock core 1 on the door panel.

[0045] Specifically, the connecting member can be a screw or a bolt, and the corresponding connecting hole 101 is set as a threaded hole. The bolt or screw passes through the threaded hole to fix the lock core 1 on the door panel.

[0046] In one embodiment, a cover plate is detachably arranged on the through hole 3, and a connecting structure is used to connect the cover plate and the base 2. The cover plate is arranged on the through hole 3 and can shield the lock cylinder 1, preventing dust or impurities from entering the lock hole 102 and affecting the unlocking.

[0047] In addition, the cover plate can be made of the same material as the base 2, and the color can be integrated with the base 2, which can increase the difficulty for a thief to find the cover plate.

[0048] Specifically, the connecting mechanism can be a connecting rope or a connecting belt, one end of which is connected to the cover plate, and the other end is connected to the base 2. After the through hole 3 is opened, the cover plate can be prevented from being lost.

[0049] According to the embodiment of the present application, on the other hand, a lock is also provided, which comprises a key 6 and a door lock. The key 6 comprises an unlocking section 601 and a handle section 602, and the unlocking section 601 and the handle section 602 are rotatably connected, so that the unlocking section 601 can pass through the first gap 5 and be inserted into the lock hole 102.

[0050] When a user needs to unlock, the unlocking section 601 and the handle section 602 are first bent, and the unlocking section 601 is inserted into the first gap 5. Since the handle section 602 and the unlocking section 601 can rotate relative to each other, even if the first gap 5 is small, the handle section 602 and the unlocking section 601 can rotate adaptively, so that the unlocking section 601 can reach the position of the through hole 3 and pass through the through hole 3 into the lock hole 102. Then, the handle section 602 can be pulled to rotate the unlocking section 601 to unlock. The handle section 602 and the unlocking section 601 can rotate relative to each other, so that the handle section 602 can be inserted into the lock hole 102 through the narrow first gap 5, improving the anti-theft effect.

[0051] It should be noted that the first gap 5 allows the unlocking section 601 to enter, but restricts other conventional unlocking tools from being inserted into the lock hole 102.

[0052] In one embodiment, as shown in Figure 1 and Figure 7 , along the axial direction X of the through hole 3, the distance H between the end of the through hole 3 close to the handle 4 and the handle 4 is less than or equal to the length L of the unlocking section 601, and along the axial direction X of the through hole 3, the distance M between the end of the lock cylinder 1 close to the handle 4 and the handle 4 is greater than or equal to the length L of the unlocking section 601.

[0053] Further, as shown in Figure 7As shown, when H is less than L and M is greater than L, the unlocking section 601 is inclined into the first gap 5 and is obliquely inserted into the through hole 3, as the depth of the unlocking section 601 inserted into the lock hole 102 gradually increases, the unlocking section 601 rotates relative to the handle section 602, the included angle between the two gradually decreases, and the unlocking section 601 gradually becomes parallel to the axial direction X. When the insertion direction of the unlocking section 601 is parallel to the axial direction X, the unlocking section 601 can be inserted into the lock hole 102, and the handle section 602 is pulled to unlock.

[0054] When H is equal to L and M is greater than L, the unlocking section 601 can be inclined or parallel to the axial direction X into the first gap 5 and be inserted into the lock hole 102 along the axial direction X, and the handle section 602 is pulled to unlock.

[0055] When H is less than L and M is equal to L, the unlocking section 601 is inclined into the first gap 5 and is obliquely inserted into the through hole 3, as the depth of the unlocking section 601 inserted into the lock hole 102 gradually increases, the unlocking section 601 rotates relative to the handle section 602, the included angle between the two gradually decreases, and the unlocking section 601 gradually becomes parallel to the axial direction X. When the insertion direction of the unlocking section 601 is parallel to the axial direction X, the unlocking section 601 can be inserted into the lock hole 102, and the handle section 602 is pulled to unlock.

[0056] When H is equal to L and M is equal to L, the unlocking section 601 is inclined or parallel to the axial direction X into the first gap 5 and is inserted into the lock hole 102 along the axial direction X, and the handle section 602 is pulled to unlock.

[0057] In one embodiment, as shown in Figure 4 and Figure 5 The handle section 602 includes a plurality of hinged pieces 6021 and a plurality of connecting shafts 6022. Each hinged piece 6021 is provided with opposite first and second connecting ends 60211 and 60212. The first connecting end 60211 is provided with a first opening hole 60213, and the second connecting end 60212 is provided with a second opening hole 60214. The connecting shaft 6022 is inserted into the second opening hole 60214 of one hinged piece 6021 and the first opening hole 60213 of the adjacent hinged piece 6021, so that the two adjacent hinged pieces 6021 are hinged. The first opening hole 60213 of the first hinged piece 6021 is hinged with the unlocking section 601. Each connecting shaft 6022 is arranged along the first direction Y, and the first direction Y is perpendicular to the axial direction X.

[0058] It should be noted that, as shown in Figure 4 and Figure 5As shown, the plurality of articulated pieces 6021 are connected by the connecting shaft 6022, and adjacent two articulated pieces 6021 can rotate relative to each other, and the rotation surface of the articulated piece 6021 is perpendicular to the first direction Y. Therefore, the handle section 602 formed by the plurality of articulated pieces 6021 is flexible in the rotation surface perpendicular to the first direction Y, and is rigid in the rotation surface perpendicular to the axial direction X. Therefore, when the unlocking section 601 is inserted into the lock hole 102, the handle section 602 is flexible, facilitating the insertion of the unlocking section 601 into the lock hole 102. The unlocking section 601 rotates in the rotation surface perpendicular to the axial direction X, and the handle section 602 is rigid when the unlocking section 601 is rotated to unlock.

[0059] Specifically, as shown in Figure 6 The articulated piece 6021 includes a first connecting plate 60215 and a second connecting plate 60216, and the first connecting plate 60215 and the second connecting plate 60216 are Z-shaped structures and are symmetrically arranged about the axial direction X. One end of the first connecting plate 60215 and the second connecting plate 60216 abuts and is fixedly connected to form a first connecting end 60211, and the other end is arranged at intervals to form a third gap 60217.

[0060] As shown in Figure 4 The first connecting end 60211 of the plurality of articulated pieces 6021 is connected to the third gap 60217 of the adjacent articulated piece 6021 by the connecting shaft 6022.

[0061] The first connecting end 60211 of the articulated piece 6021 is inserted into the third gap 60217 of the adjacent articulated piece 6021 for connection.

[0062] Specifically, when M is greater than L, the articulated piece 6021 can be inserted into the through hole 3.

[0063] In one embodiment, as shown in Figure 4 The key 6 further includes an articulated seat 603, which is provided with a fixed end and an articulated end. The fixed end is fixedly connected to the unlocking section 601, and the articulated end is articulated to the first opening 60213 of the articulated piece 6021.

[0064] The fixed end of the articulated seat 603 is fixed to the unlocking section 601, and the articulated end is articulated to the first articulated piece 6021, facilitating the connection of the handle section 602 and the unlocking section 601.

[0065] In one embodiment, as shown in Figure 4As shown, the hinged seat 603 includes two plate members 6031 and a pin shaft 6032, the two plate members 6031 are oppositely arranged and each is provided with a first end and a second end, the first ends of the two plate members 6031 are fixed on the two sides of the unlocking section 601 respectively, the second ends of the two plate members 6031 form a second gap 6033 therebetween, the second ends of the two plate members 6031 are correspondingly provided with through holes, the first connecting end 60211 of the hinged member 6021 penetrates into the second gap 6033, and the through holes and the first opening 60213 are connected by the pin shaft 6032. The through holes and the first opening 60213 are both rotationally connected with the pin shaft 6032.

[0066] In one embodiment, the hinged seat 603 further includes a fixing shaft 6034, the first ends of the two plate members 6031 are provided with fixing holes, the unlocking section 601 is correspondingly provided with mounting holes, and the fixing shaft 6034 is inserted into the fixing holes and the mounting holes to fixedly connect the two plate members 6031 with the unlocking section 601.

[0067] Specifically, the base 2 is provided with a fixing member 7, which is used for being fixed on the door plate. The fixing member 7 can be a pin, which is inserted into the door plate.

[0068] According to the embodiments of the present application, on the other hand, a security door is also provided, which includes a door plate, a lockset, and a base 2 installed on the door plate.

[0069] Specifically, the door plate is provided with a mounting groove, the lock cylinder 1 is installed in the mounting groove, and the slot of the mounting groove is oppositely arranged with the through hole 3.

[0070] In one specific embodiment, the door lock further includes a guide sleeve 8, which is sequentially provided with a first-stage guide channel 801, a second-stage guide channel 802, and a connecting channel 803 in sequence along the axial direction X and in communication with each other, one end of the lock cylinder 1 provided with a lock hole 102 penetrates into and is installed in the connecting channel 803, the diameter of the end of the first-stage guide channel 801 away from the connecting channel 803 is greater than the diameter of the end of the second-stage guide channel 802 away from the connecting channel 803, and the first cross section of the end of the second-stage guide channel 802 close to the lock cylinder 1 is circular, the diameter of the first cross section is equal to the diagonal line of the lock hole 102, and the second-stage guide channel 802 is used for guiding the key 6 into the lock hole 102.

[0071] The base 2 is installed on the door plate, and the lock hole 102 of the lock cylinder 1 corresponds to the through hole 3 of the base 2. Figure 10 As shown, in the process of unlocking by the user, first, the unlocking section 601 is stretched into the first-stage guide channel 801, and the size of the first-stage guide channel 801 is greater than the size of the unlocking section 601, so that the unlocking section 601 can easily enter the first-stage guide channel 801.

[0072] As shown in Figure 10 and Figure 13As shown, the first cross-section of the second-level guide channel 802 at one end close to the lock hole 102 is circular, the first cross-section is perpendicular to the axial direction X of the guide sleeve 8, the cross-section of the lock hole 102 is rectangular, and the diameter of the cross-section of the second-level guide channel 802 is equal to the diagonal of the cross-section of the lock hole 102. Therefore, during the movement of the unlocking section 601 along the first-level guide channel 801 to the lock hole 102, it can be accurately inserted into the lock hole 102 through the guiding effect of the second-level guide channel 802, and then the handle section 602 is rotated to unlock, thereby reducing the difficulty of unlocking for the user.

[0073] It needs to be further explained that, Figure 10 and Figure 13 As shown, the four corners of the rectangle are all located on the edge of the circle, forming an inscribed rectangle in the circle, and the unlocking segment 601 matches the key hole 102. When the unlocking segment 601 abuts against the lock core 1, the four corners of the unlocking segment 601 at one end close to the lock core 1 abut against the inner wall of the second-level guide channel 802, so that the axis of the key 6 coincides with the axis of the second-level guide channel 802. Therefore, by rotating the handle segment 602, the unlocking segment 601 can be rotated about the central axis of the second-level guide channel 802, and the unlocking segment 601 can be aligned with the key hole 102 by slightly rotating. The user applies pressure on the unlocking segment 601 during the rotation process, and when the unlocking segment 601 is aligned with the key hole 102, the unlocking segment 601 can be inserted into the key hole 102.

[0074] In one embodiment, Figure 10 As shown, the second-level guide channel 802 includes a first section 8021 and a second section 8022 that are interconnected. The first section 8021 is close to the lock core 1 and is connected to the connecting channel 803. The second section 8022 is connected to the first-level guide channel 801. The second section 8022 gradually narrows from the first-level guide channel 801 toward the connecting channel 803.

[0075] The size of the first-level guide channel 801 is larger than that of the handle section 602, which facilitates the entry of the handle section 602 and guides the unlocking section 601 into the second section 8022 of the second-level guide channel 802. The second section 8022 gradually narrows as it extends toward the first section 8021, making it easier to guide the unlocking section 601 from the second section 8022 to the first section 8021. The first section 8021 can guide the unlocking section 601 into the keyhole 102.

[0076] Specifically, a step 13 is formed between the end of the first section 8021 close to the lock hole 102 and the end of the connecting channel 803 , and one end of the lock core 1 abuts against the step 13 .

[0077] Specifically, the second cross section of the first section 8021 perpendicular to the axis X is the same as the first cross section.

[0078] In a specific embodiment, Figure 9 andFigure 11 As shown, the outer wall of the guide sleeve 8 is provided with a limiting strip 9. The limiting strip 9 extends along the axial direction X of the guide sleeve 8, and the end closest to the first-stage guide channel 801 abuts the end of the through hole 3. The end of the first-stage guide channel 801, which is away from the second-stage guide channel 802, corresponds to the through hole 3. The limiting strip 9 abuts the base 2. The base 2 can press the guide sleeve 8 into the door panel via the limiting strip 9, thereby pressing the lock cylinder 1 and limiting its movement.

[0079] In a specific embodiment, a plurality of limiting strips 9 are provided, the plurality of limiting strips 9 are arranged in parallel, and the plurality of limiting strips 9 are spaced apart along the circumference of the guide sleeve 8. The plurality of limiting strips 9 are all in contact with the base 2, thereby improving the stability of the base 2 pressing the lock cylinder 1.

[0080] In a specific embodiment, Figure 12 As shown, at least one limiting strip 9 is provided with a plurality of grooves 14 , and the plurality of grooves 14 are distributed at intervals along the axial direction X of the guide sleeve 8 .

[0081] It needs to be explained that in order to meet the needs of door panels of various sizes, the size of the guide sleeve 8 during production will be slightly larger. After the lock core 1 and the guide sleeve 8 are installed, the guide sleeve 8 will extend out of the door panel to a certain length. The excess guide sleeve 8 needs to be cut off and cut off at the groove 14 to ensure the accuracy of the cut.

[0082] It should be noted that if Figure 12 As shown, the limiting strip 9 is provided with a digital scale, which represents the distance from this position to the lock hole 102. The marked digital scale can clearly know the distance from the cutting position to the lock hole 102.

[0083] Specifically, such as Figure 11 As shown, the door lock also includes a locking piece 10, the side wall of the guide sleeve 8 is connected to a connecting plate 11, the connecting plate 11 is provided with a first connecting hole 12, and the lock core 1 is provided with a second connecting hole 101 corresponding to the first connecting hole 12. The guide sleeve 8 and the lock core 1 are locked by inserting the locking piece 10 in the first connecting hole 12 and the second connecting hole 101.

[0084] Below is an embodiment, combined with Figures 1 to 13 A comprehensive explanation of all the above plans is given.

[0085] Base 2 is mounted on the door panel. Lock hole 102 of lock cylinder 1 corresponds to through hole 3 of base 2. Handle 4 is connected to base 2 to block through hole 3, reducing the probability of lock hole 102 being discovered and lowering the risk of theft. A first gap 5 is formed between handle 4 and base 2. Through hole 3 is located within first gap 5. When a thief attempts to open the door using a lock picking tool, they need to insert the tool into lock hole 102 through first gap 5, making unlocking more difficult and improving the anti-theft effect.

[0086] When the lock needs to be opened, according to the relationship between the distance H between the through hole 3 and the handle 4 and the length L of the opening segment 601 and the relationship between the distance M between the lock core 1 and the handle 4 and the length L of the opening segment 601, the way in which the handle segment 602 enters the first gap 5 and is inserted into the lock hole 102 is determined.

[0087] When H is less than L and M is greater than L, the opening segment 601 is inclined to enter the first gap 5 and is obliquely inserted into the through hole 3. As the depth of the opening segment 601 inserted into the lock hole 102 gradually increases, the opening segment 601 slowly becomes parallel to the axial direction X. When the insertion direction of the opening segment 601 is parallel to the axial direction X, the opening segment 601 can be inserted into the lock hole 102, and the handle segment 602 is pulled to open the lock.

[0088] When H is equal to L and M is greater than L, the opening segment 601 can be inclined or parallel to the axial direction X to enter the first gap 5 and be inserted into the lock hole 102 along the axial direction X, and the handle segment 602 is pulled to open the lock.

[0089] When H is less than L and M is equal to L, the opening segment 601 is inclined to enter the first gap 5 and is obliquely inserted into the through hole 3. As the depth of the opening segment 601 inserted into the lock hole 102 gradually increases, the opening segment 601 slowly becomes parallel to the axial direction X. When the insertion direction of the opening segment 601 is parallel to the axial direction X, the opening segment 601 can be inserted into the lock hole 102, and the handle segment 602 is pulled to open the lock.

[0090] When H is equal to L and M is equal to L, the opening segment 601 is inclined or parallel to the axial direction X to enter the first gap 5 and be inserted into the lock hole 102 along the axial direction X, and the handle segment 602 is pulled to open the lock.

[0091] The plurality of articulated pieces 6021 are connected by the connecting shaft 6022, and adjacent two articulated pieces 6021 can rotate relative to each other. The rotation surface of the articulated piece 6021 is perpendicular to the first direction Y. Therefore, the handle segment 602 formed by the plurality of articulated pieces 6021 is flexible on the rotation surface perpendicular to the first direction Y and rigid on the rotation surface perpendicular to the axial direction X. Therefore, when the opening segment 601 is inserted into the lock hole 102, the handle segment 602 is flexible, facilitating the insertion of the opening segment 601 into the lock hole 102. When the opening segment 601 is rotated to open the lock, the handle segment 602 is rigid and can pull the opening segment 601 to rotate.

[0092] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
