Description

Technical Field

[0001] This utility model relates to the field of security lock technology, and in particular to security door locks. Background Technology

[0002] A safety lock is a protective device used to safeguard personal safety. Its core function is to reliably close and lock doors, equipment, or specific protected locations, thereby preventing unauthorized opening or accidental misoperation. A safety lock typically consists of a matching locking element, a bolt, a lock cylinder, a lock body, and related transmission and control mechanisms. It controls the extension and retraction of the bolt through mechanical or electronic actuation, enabling the door or equipment to switch between opening and closing.

[0003] Traditional security locks consist of a lock body and a matching locking element. The lock body includes an integrally connected lock body and lock cylinder. The sensing components of traditional security locks are located in the lock body. When it is necessary to adjust the direction for locking in conjunction with the matching locking element, the entire lock body and lock cylinder must be turned simultaneously. At this time, the display and unlocking components on the lock body will not be facing the user, thus affecting the user experience. Utility Model Content

[0004] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a security door lock that solves at least one of the aforementioned technical problems. It has the advantage that when the locking direction needs to be adjusted and matched with the locking components, the locking direction can be adjusted simply by rotating the lock head, thus avoiding the situation where the display components and unlocking components on the lock body cannot face the user.

[0005] To achieve the above objectives, this utility model provides a security door lock, comprising: The lock body includes a lock body and a lock head disposed on the top of the lock body and detachably connected to the lock body. A first sensing component is disposed on one side of the lock head. A locking component is disposed inside the lock body. A clearance through hole is disposed on the top of the lock body for the locking end of the locking component to extend out. A lock hole communicating with the clearance through hole is disposed on one outer side wall of the lock head. A control component is disposed inside the lock body. The first sensing component is electrically connected to the control component through a contact electrical connection component.

[0006] Optionally, a matching locking member is included, one end of which is provided with a locking pin for insertion into a lock hole to cooperate with the locking component for locking, and a second sensing component adapted to the first sensing component is provided on the outside of the matching locking member.

[0007] Optionally, the lock body is provided with connecting holes at the four corners of the top, and the top of the lock head is provided with a first connecting through hole that connects to its bottom. The first connecting through hole corresponds to the connecting hole, and the connector can be passed through the first connecting through hole and connected to the connecting hole.

[0008] Optionally, the locking component includes a solenoid valve, which includes a valve body and a valve core. When the valve body is activated, it can attract the valve core, causing the valve core to move away from the lock head, thereby achieving the unlocked state.

[0009] Optionally, an annular limiting member is provided on the outer wall of the valve core, and a spring is provided on the outer wall of the valve core. One end of the spring abuts against the end of the annular limiting member near the valve body, and the other end of the spring abuts against the valve body. When the valve body is not activated, the spring pushes the valve core toward the lock head to achieve a locked state.

[0010] Optionally, the end of the valve core away from the valve body is connected to the buckle core via a connecting device. In the locked state, the buckle core extends out of the avoidance through hole and enters the lock hole. In the unlocked state, the buckle core retracts from the lock hole into the avoidance through hole.

[0011] Optionally, the connecting device includes a block with a limiting hole, and an unlocking component is rotatably disposed on the side wall of the lock body. The unlocking component includes a rotating unlocking head rotatably disposed on the side wall of the lock body and a limiting pin inserted into the limiting hole. The limiting pin is disposed at the edge of the rotating unlocking head near the connecting component.

[0012] Optionally, the end of the buckle core away from the connecting device is provided with multiple guide slopes.

[0013] Optionally, the front of the lock body is provided with multiple countersunk grooves, and the bottom of the countersunk grooves is provided with second connecting through holes penetrating the opposite sides thereon. The matching locking member is provided with multiple countersunk through holes connecting the opposite sides thereon.

[0014] Optionally, a display component for displaying the locked state is provided on the outer side wall of the lock body, and the display component is electrically connected to the control component.

[0015] Compared with the prior art, the advantages of this application are: This invention features a detachable connection between the lock cylinder and lock body, with the first sensing component positioned on the outside of the lock cylinder and electrically connected to the control component via a contact-type electrical connection component. This allows for individual adjustment of the lock cylinder's orientation to suit different installation needs, while ensuring that the display and unlocking components on the lock body always face the user. This solves the problem of misalignment of operating or alerting components such as the unlocking and display components caused by the overall rotation of traditional security locks, thus improving the user experience.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," "back," "side," and "circumferential" used in this utility model to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used to distinguish multiple parts or structures with the same or similar structures, and do not indicate any special limitation on the arrangement order or connection relationship.

[0021] Please refer to Figures 1 to 6 This utility model embodiment provides a security door lock, including: a lock body 110, the lock body 110 including a lock body 111 and a lock head 112 disposed on the top of the lock body 111 and detachably connected to the lock body 111, the lock body 111 having a locking component inside, the top of the lock body 111 having a clearance through hole 116 for the locking end of the locking component to extend out, and an outer side wall of the lock head 112 having a lock hole 117 communicating with the clearance through hole 116. Further, the lock body 110 refers to a structure composed of the lock body 111 and the lock head 112, the lock head 112 being disposed on the top of the lock body 111 and detachably connected, specifically using a threaded structure, allowing the lock head 112 to be adjusted independently without affecting the position of the lock body 111. The first sensing component 113 is a sensor used to detect the state of the matching locking element 120. Specifically, it can be an RFID identification component (radio frequency identification technology). The locking element is the mechanism that achieves mechanical locking, specifically a solenoid valve 130 or a motor-driven bolt. It is located inside the lock body 111 and performs the locking action through the locking end. The clearance through hole 116 is a channel hole that allows the locking end to extend and retract. Specifically, it can be a circular through hole, located at the top of the lock body 111 and communicating with the lock hole 117 to form a locking path. The lock hole 117 is the hole for the insertion of the lock pin 121. The control component (not shown) is a circuit module used to process signals and control the locking element. Specifically, it can be implemented using an integrated circuit board and is electrically connected to the first sensing component 113 to trigger locking or unlocking operations. The contact-type electrical connection assembly refers to the physical connection structure that realizes signal transmission. Specifically, it includes a spring contact pin 150 set on the top of the lock body, a first conductive plate 151 electrically connected to the spring contact pin 150, a contact point 152 set on the bottom of the lock head, and a second conductive plate 153 electrically connected to the contact point 152. In this embodiment, the lock head 112 is adapted to a swing door (hinges are installed on the side of the door) when it does not need to rotate, and is adapted to a sliding door when it needs to rotate.

[0022] In this embodiment, a matching locking member 120 is included. One end of the matching locking member 120 is provided with a locking pin 121 for insertion into the lock hole 117 and engaging with the locking component for locking. Further, the locking pin 121 adopts a cylindrical metal structure, and its diameter forms a clearance fit with the inner diameter of the lock hole 117. The second sensing component 122 can be an RFID identification component (radio frequency identification technology), and its installation position forms a planar contact with the outer wall of the lock head 112, thus corresponding to the first sensing component 113. When the locking pin 121 is inserted into the lock hole 117, the second sensing component 122 contacts the first sensing component 113. If correctly identified, the solenoid valve is de-energized, the locking component locks, and a green light illuminates, indicating normal operation. If identification fails, or the matching device is mismatched, the solenoid valve remains energized, and a red light illuminates.

[0023] In this embodiment, the lock body 111 has four connecting holes 123 at its top corners, and the lock head 112 has a first connecting through hole 124 at its top, connecting to its bottom. The first connecting through hole 124 corresponds to the connecting holes 123, allowing the connector 125 to pass through the first connecting through hole 124 and connect to the connecting hole 123. Furthermore, the connecting holes 123 are distributed at the four corners of the top of the lock body 111, forming a symmetrical layout. The connecting holes 123 are threaded holes. The first connecting through hole 124 is a through hole penetrating from the top to the bottom of the lock head 112, and its diameter matches the outer diameter of the connector 125. The connector 125 is a bolt or screw, with a length greater than the thickness of the lock head 112, which passes through the first connecting through hole 124 and engages with the threaded structure of the connecting hole 123 to lock it in place. The connection interface between the lock head 112 and the lock body 111 is fixed at multiple points through four sets of connecting holes 123 and the first connecting through hole 124. The axes of the connecting holes 123 and the first connecting through hole 124 coincide to ensure the installation accuracy of the lock head 112 and the lock body 111.

[0024] Specifically, when the direction of the lock head 112 needs to be adjusted, the connection between the lock head 112 and the lock body 111 is released. The lock head 112 is rotated to the target angle, preferably 90°, so that the first connecting through hole 124 is re-aligned with the connecting hole 123 on the top of the lock body 111. Then, the connector 125 is inserted and tightened to complete the adjustment of the lock head 112's direction. The connecting holes 123 distributed at the four corners maintain their correspondence with the first connecting through hole 124 after the lock head 112 is rotated, avoiding connection failure due to angular displacement. When the lock head 112 rotates alone, the position of the lock body 111 remains unchanged, and the display component 146 and the unlocking component 139 are always in the preset direction, ensuring user operation convenience. The connecting hole 123 and the first connecting through hole 124 use a through hole and threaded hole fit, and the lock head 112 and the lock body 111 are detachably connected by mechanical fastening, which is simple in structure and has high connection stability.

[0025] In this embodiment, the locking component includes a solenoid valve 130, which comprises a valve body 131 and a valve core 132. When the valve body 131 is activated, it can attract the valve core 132, causing the valve core 132 to move away from the lock head 112, thereby achieving an unlocked state. Furthermore, the valve body 131 adopts an electromagnetic coil structure, which generates a magnetic field force when energized; the valve core 132 is made of a magnetically conductive material.

[0026] Specifically, when the control component sends an unlocking command to the solenoid valve 130, the valve body 131 is energized, generating a magnetic force that attracts the valve core 132, causing it to move axially toward the inside of the lock body 111. The displacement of the valve core 132 disengages the locking end from the lock hole 117, releasing the constraint on the mating locking member 120. When the control component cuts off the power, the magnetic force of the valve body 131 disappears, and the valve core 132 returns to its initial position under the action of the reset mechanism, with the locking end re-inserting into the lock hole 117. This structure achieves rapid switching of the locking state through electromagnetic drive, eliminating the need for complex mechanical transmission mechanisms.

[0027] In this embodiment, an annular limiting member 133 is provided on the outer wall of the valve core 132, and a spring 134 is provided on the outer wall of the valve core 132. One end of the spring 134 abuts against the end of the annular limiting member 133 near the valve body 131, and the other end of the spring 134 abuts against the valve body 131. When the valve body 131 is not activated, the spring 134 pushes the valve core 132 toward the lock head 112 to achieve a locked state. Furthermore, the annular limiting member 133 is fixed to the outer wall of the valve core 132 to form a stepped structure, and the spring 134 is sleeved on the outside of the valve core 132 and compressed between the annular limiting member 133 and the valve body 131. When compressed, the spring 134 stores elastic potential energy, which is converted into mechanical energy to push the valve core 132 when released.

[0028] Specifically, when the solenoid valve 130 is energized, the valve body 131 generates a magnetic force to overcome the elastic force of the spring 134 and attract the valve core 132. The spring 134 is compressed between the annular limiting member 133 and the valve body 131 to achieve unlocking.

[0029] In this embodiment, the end of the valve core 132 away from the valve body 131 is connected to the latch core 136 via a connecting device. In the locked state, the latch core 136 extends out of the clearance through hole 116 and enters the lock hole 117. In the unlocked state, the latch core 136 retracts from the lock hole 117 and avoids the clearance through hole 116. The connecting device includes a block 137, on which a limit hole 138 is provided. An unlocking component 139 is rotatably disposed on the side wall of the lock body 111. The unlocking assembly 139 includes a rotating unlocking head 140 rotatably disposed on the side wall of the lock body 111 and a limiting pin 141 inserted into the limiting hole 138. The limiting pin is disposed on the edge of the rotating unlocking head 140 near the connecting assembly. Furthermore, the block 137 serves as an intermediate connecting member 125 between the valve core 132 and the latch core 136. Its limiting hole 138 and the limiting pin 141 form a sliding fit, restricting the block 137 to move only along the axial direction of the valve core 132. The rotating unlocking head 140 is detachably connected to the block 137 via the limiting pin 141. The rotating unlocking head 140 can be rotated counterclockwise, and the limiting pin 141 moves along the edge trajectory of the limiting hole 138 to press down the valve core 132, thereby causing the valve core 132 to overcome the elastic force of the spring 134 and move downward to reach the unlocked state. The rotating unlocking head 140 can be rotated clockwise, and the limiting pin 141 moves in the opposite direction along the edge trajectory of the limiting hole 138 to reset, thereby causing the valve core 132 to reset to the locked state. Specifically, in the unlocked state, the limiting pin 141 can also prevent the locking core 136 from moving upward excessively.

[0030] In this embodiment, the end of the buckle core 136 away from the connecting device is provided with multiple guide slopes 142. The end of the locking pin 121 is provided with a limiting locking protrusion. Furthermore, the guide slopes 142 are provided at the end edge of the buckle core 136, with two or four slopes and an inclination angle of 30°-60°. The slopes are formed by cutting or stamping. When the locking pin 121 is inserted into the lock hole 117, the limiting locking protrusion pushes the buckle core 136 downward through the guide slopes 142. After the limiting locking protrusion has passed, the buckle core 136 moves upward under the action of the spring 134 to prevent the limiting locking protrusion from disengaging from the lock hole 117, thereby achieving locking.

[0031] In this embodiment, the front of the lock body 111 is provided with a plurality of countersunk grooves 143, and the bottom of the countersunk grooves 143 is provided with a second connecting through hole 144 penetrating its opposite sides. Further, the matching locking member 120 is provided with a plurality of countersunk through holes 145 connecting its opposite sides. The lock body 111 is connected to the door frame through the second connecting through holes 144, and the matching locking member 120 is connected to the door through the countersunk through holes 145. A display component 146 for displaying the locked state is provided on the outer wall of the lock body 111. The display component 146 is electrically connected to the control component. The display component 146 can be a display screen or multiple indicator lights of different colors, using different colored indicator lights to indicate the operating state of the present invention.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
