Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a bolt lock with power control function. Background Technology

[0002] In universities and dormitories, bolt locks are widely used due to their simple structure, low cost, and high reliability. These locks are usually purely mechanical, and users manually lock and unlock the door. The state (locked or unlocked) is an independent, localized physical event. However, this widely used bolt lock has a significant drawback: its locking action only indicates that the user has left the physical space, but it cannot sense or control the electrical environment inside the dormitory. Specifically, when students tighten the bolt and leave the dormitory for class or go out, the chargers, converters, desk lamps, and other electrical devices on the indoor sockets are often still in standby or working state. These devices, operating without supervision for a long time, are prone to overheating, malfunction, or deterioration, which can lead to leakage, short circuits, or even fires, posing a serious electrical safety hazard. Utility Model Content

[0003] In order to overcome the shortcomings mentioned in the background art, the present invention provides a bolt lock with power control function.

[0004] The technical solution of this utility model is as follows: a bolt lock with power control function includes a square shell, a main bolt slidably connected to the front side of the square shell, a first auxiliary bolt and a second auxiliary bolt slidably connected to the rear side, first baffles slidably connected to the front and rear sides of the square shell respectively, the first baffle on the front side is rotatably connected to the main bolt, the first baffle on the rear side is rotatably connected to the first auxiliary bolt, the two first baffles are fixedly connected to a connecting plate, the connecting plate is slidably connected to a slide rod, a fixing plate is fixedly connected inside the square shell, the fixing plate is slidably connected to the slide rod, the fixing plate is fixedly connected to a fixing rod, the fixing rod is slidably connected to the connecting plate, and a micro switch is provided inside the square shell, the trigger position of the micro switch corresponding to the end of the sliding stroke of the slide rod.

[0005] Furthermore, a knob is rotatably connected to the rear side of the square shell, and a first gear is connected to one end of the knob inside the shell. A first toothed plate that meshes with the first gear is slidably connected inside the square shell. A limit rod is fixed to the top of the first toothed plate, and a limit hole is opened on the slide rod. The limit rod can be inserted into the limit hole to limit the movement of the slide rod.

[0006] Furthermore, a spring is fitted onto the fixed rod, with both ends of the spring abutting against the fixed plate and the connecting plate respectively. A tension spring is connected between the side of the connecting plate away from the fixed plate and the sliding rod.

[0007] Furthermore, the tension of the tension spring is greater than the preload of the spring.

[0008] Furthermore, a second baffle is slidably connected to the rear side of the square shell, a rotating shaft is rotatably connected inside the square shell, a second gear and a third gear are fixedly connected to the rotating shaft, a second toothed plate and a third toothed plate are slidably connected inside the square shell, the second baffle is rotatably connected to the second auxiliary pin and fixedly connected to the third toothed plate, the third toothed plate meshes with the third gear, the second gear meshes with the second toothed plate, and the moving end of the second toothed plate is located on the moving path of the connecting plate to restrict the movement of the connecting plate.

[0009] The beneficial effects are as follows: When the main latch is locked, it drives the linkage mechanism, causing the slide bar to move and triggering the micro switch to control the wireless module to send a signal indicating that the user has left home. This achieves automatic and reliable linkage between mechanical locking and intelligent power-off, binding the user's action of leaving the door with the shutdown of non-essential power supplies throughout the house. This avoids energy waste and the risk of equipment running idle due to forgetting to turn off electrical appliances after being away for a long time, and prevents fire safety accidents that may be caused by electrical appliances overheating, short circuits, or malfunctions.

[0010] This invention enables the external operation of actively and purely mechanically locking the main latch from the inside by pushing the second auxiliary latch from the inside, causing the second toothed plate to move down and block the movement path of the connecting plate. This gives the indoor user complete control over preventing accidental locking, avoiding the dangerous situation where outdoor personnel maliciously or accidentally push the main latch and lock the user inside the house, thus eliminating the personal safety risks and emergency rescue problems caused by this.

[0011] This invention enables a mechanical selective locking of the trigger mechanism in temporary outing scenarios by rotating a knob to drive the limit rod downward and insert it into the limit hole of the slide rod. This allows users to maintain indoor power supply while physically locking the door, avoiding the interruption of necessary electrical appliances due to a power outage triggered during a short absence. It resolves the conflict between safety and convenience in temporary outing scenarios. Attached Figure Description

Detailed Implementation

[0018] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] A bolt lock with power control function, as described above Figures 1 to 5 The bolt lock in this embodiment mainly includes a square shell 1, which serves as the mounting carrier and outer shell for all internal mechanisms and external operating components. A main bolt 2 is slidably connected to the front side of the square shell 1, typically facing outwards or towards the door frame. A first auxiliary bolt 3 and a second auxiliary bolt 4 are slidably connected to the rear side, typically facing inwards. The movement of the main bolt 2 is the core mechanism for triggering the intelligent power-off function. At the end of the main bolt 2, a first blocking plate 5 is connected via a rotating connection point such as a hinge or pin. Similarly, another first blocking plate 5 is slidably connected to the end of the first auxiliary bolt 3. These two first blocking plates 5 do not move independently but are connected by a connecting plate 6. The components are rigidly connected together to form a linkage frame. A sliding rod 7 is slidably mounted on the connecting plate 6. A fixed plate 8 is fixed inside the square shell 1. The sliding rod 7 also passes through this fixed plate 8 and can slide along it. A fixed rod 9 is also fixed on the fixed plate 8. The fixed rod 9 is parallel to the sliding rod 7 and passes through the connecting plate 6, so that the connecting plate 6 can slide smoothly along the axial direction of the fixed rod 9, i.e., the left and right direction. At the end of the movement path of the sliding rod 7, a micro switch 10 is correspondingly provided. The micro switch 10 can be electrically connected to a built-in or external wireless transmission module, such as a 433MHz module.

[0020] Reference Figures 2 to 5To meet the need for uninterrupted power supply during temporary absences, a manual locking trigger mechanism is provided. A rotatable knob 11 is installed on the rear side of the square shell 1. One end of the knob 11 that extends into the shell is connected to a first gear 12. A vertically arranged first toothed plate 13 meshes with the first gear 12. A limiting rod 14 is fixed at the top of the first toothed plate 13. Correspondingly, a limiting hole is provided on the slide rod 7. When the knob 11 is rotated, the limiting rod 14 can be lowered through the gear toothed plate transmission and accurately inserted into the limiting hole of the slide rod 7.

[0021] Reference Figure 3 and Figure 4 In order to enable the connecting plate 6 and the slide rod 7 to reset when not locked and to transmit force, a spring 15 is fitted on the fixed rod 9, with one end abutting against the fixed plate 8 and the other end abutting against the connecting plate 6. At the same time, a tension spring 16 is connected between the right side of the connecting plate 6 away from the fixed plate 8 and the right end of the slide rod 7. In design, the initial tension of the tension spring 16 is greater than the preload of the spring 15.

[0022] Reference Figures 3 to 5 To prevent accidental locking of occupants, a special anti-lock mechanism is installed. A second baffle plate 17 is slidably connected to the rear of the square shell 1, and is rotatably connected to the second auxiliary pin 4. A rotating shaft 18 is provided inside the shell, on which a second gear 19 and a third gear 20 are fixed. A third toothed plate 22 is fixedly connected to the second baffle plate 17 and meshes with the third gear 20. Another second toothed plate 21 meshes with the second gear 19. When the second auxiliary pin 4 is pushed from inside, the gear set 20 and 19 will rotate through the second baffle plate 17 and the third toothed plate 22, ultimately driving the second toothed plate 21 to move downward. After the lower end of the second toothed plate 21 extends, it is exactly in the path of the connecting plate 6 moving to the right, forming a mechanical obstruction.

[0023] Normal exit mode: When the user needs to leave for a long time, this mode is used. The user closes the door directly and then pushes the bolt on the main bolt 2 to the right from the outside of the door until it is fully extended out of the square shell 1 and inserted into the lock hole of the door frame to achieve the main lock. Then, the user can use a physical lock (such as a padlock) to fix the bolt.

[0024] During this process, the main pin 2, which moves to the right, causes the first blocking plate 5 on the front side to move to the right. Since the two first blocking plates 5 are fixedly connected by the connecting plate 6, the first blocking plate 5 on the rear side and the connecting plate 6 move to the right synchronously. The connecting plate 6 slides along the fixed rod 9 and begins to compress the spring 15 sleeved on the fixed rod 9. At the same time, since the tension of the tension spring 16 is greater than the initial resistance of the spring 15, the connecting plate 6 pulls the sliding rod 7 to move to the right synchronously through the tension spring 16. When the main pin 2 is locked in place, the sliding rod 7 just moves to the end of its stroke, triggering the micro switch 10. After the micro switch 10 is triggered, it can control the 433MHz wireless module connected to it to send a "door locked" or "away" signal. This signal can be received by the home smart gateway, which will then cut off the unnecessary power circuits such as indoor lighting and sockets to achieve energy saving and safety protection.

[0025] When the user is indoors, an indoor anti-locking mode is used to prevent malicious locking by people outside: When a user pushes the second auxiliary bolt 4 from inside the door to lock it, the second auxiliary bolt 4 causes the second blocking plate 17 to move to the right. The second blocking plate 17 then causes the third toothed plate 22, which is fixed to it, to slide to the right. The third toothed plate 22 drives the third gear 20, which meshes with it, to rotate. Since the third gear 20 is fixedly connected to the rotating shaft 18, it drives the shaft and the second gear 19, which is fixedly connected to it, to rotate synchronously. The rotating second gear 19 drives the second toothed plate 21, which meshes with it, to move downward. The lower end of the second toothed plate 21 then extends out and blocks the movement path of the connecting plate 6. At this time, if someone outside the door tries to push the main bolt 2, the attempt of the main bolt 2 to drive the connecting plate 6 to move to the right will be directly blocked by the second toothed plate 21. Since the connecting plate 6 cannot move, the entire linkage mechanism is locked, and the main bolt 2 cannot be pushed to the locked position, thus fundamentally eliminating the risk of being accidentally locked from the outside. This mode only realizes the mechanical anti-lock function and does not trigger the micro switch 10.

[0026] When a user only needs to go out briefly (such as to pick up a package or take out the trash) or when appliances need to be kept running indoors, the temporary outing mode is used: Before leaving the house, the user rotates the knob 11 indoors. The rotation of the knob 11 drives the first gear 12 on its shaft to rotate. The first gear 12 drives the first toothed plate 13 that meshes with it to move downwards. The limiting rod 14 fixed to the top of the first toothed plate 13 then descends. The limiting rod 14 is inserted into the preset limiting hole on the slide rod 7 to lock the position of the slide rod 7.

[0027] After completing the above settings, the user can close the door as usual and push the main latch 2 to lock the door. During the locking process, the connecting plate 6 can still move to the right and compress the spring 15 normally. However, since the slide bar 7 is mechanically locked by the limit rod 14, it cannot be pulled by the tension spring 16. Therefore, the slide bar 7 can never move to the position that triggers the micro switch 10. The 433MHz wireless module will not send a power-off signal, and the indoor power supply remains normally connected.

[0028] After the user returns, rotating knob 11 in the opposite direction will raise the limit rod 14 and disengage it from the limit hole, thereby releasing the lock on the slide rod 7 and restoring the device to the triggerable state.

[0029] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
