Description

Technical Field

[0001] The present application relates to the technical field of lock body detection, and in particular to a multifunctional lock body quality and life detection device. Background Art

[0002] When the smart lock is in use, you input a password or fingerprint to give it an unlocking signal. The motor in the smart lock drives the main lock tongue switch to rotate, so that the main lock tongue is unlocked. Then the handle of the smart lock is rotated forward to a certain angle to drive the oblique lock tongue to retract into the lock body. Pull the handle to complete the door opening action. The life detection of the lock tongue of the smart lock usually needs to be tested tens of thousands or even hundreds of thousands of times. If it is tested manually, the detection efficiency is low and the labor cost is high.

[0003] The smart lock is also provided with an induction lock tongue, an induction element and an induction motor. The induction lock tongue is pushed into the lock body. The induction element receives the induction signal, controls the induction motor to rotate, unlocks the oblique lock tongue, and allows the oblique lock tongue to be telescopically movable.

[0004] In the related art, a driving device is used to drive the main lock tongue switch to rotate, so that the main lock tongue is extended and retracted to detect the service life of the smart lock. However, the main lock tongue cannot be accurately detected only by driving the main lock tongue switch to rotate, and the length of the main lock tongue extending out of the lock body cannot be accurately measured, which reduces the accuracy of the detection. Summary of the invention

[0005] In view of this, the present application provides a multifunctional lock body quality and life detection device to solve or improve the problem of being unable to accurately measure the extended length of the main lock tongue.

[0010] The controller is communicatively connected with the driving mechanism and the first distance sensor respectively.

[0011] Beneficial effect: The driving mechanism drives the main lock tongue switch to rotate, thereby driving the main lock tongue to extend out of the lock body. The first distance sensor detects the length of the main lock tongue extending out of the lock body and transmits the data information to the controller. The controller determines whether the length standard of the main lock tongue extension is reached. It can accurately detect whether the main lock tongue is stuck, and then determine the service life of the lock body. Compared with the prior art, which can only determine whether the main lock tongue extends out of the lock body but cannot determine whether the length extending out of the lock body reaches the standard, the solution of the present application has higher accuracy in lock body life detection.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0033] The smart lock is also provided with an induction lock tongue 20, an induction element and an induction motor. A limiting groove is provided on the oblique lock tongue 18. A limiting plate is connected to the output shaft of the induction motor. When the induction lock tongue 20 extends out of the lock body 2, the limiting plate is inserted into the limiting groove to limit the telescopic movement of the oblique lock tongue 18. The induction lock tongue 20 is pushed into the lock body 2, and the induction element receives the induction signal to control the rotation of the induction motor. The limiting plate is away from the limiting groove, so that the oblique lock tongue 18 can be telescopically moved.

[0034] Combine the following Figures 1 to 5 , describing an embodiment of the present application.

[0035] According to an embodiment of the present application, a multifunctional lock body quality life detection device is provided, comprising: a mounting plate 1, a drive mechanism, a first distance sensor 4 and a controller 5;

[0036] Specifically, the mounting plate 1 is used to mount the lock body 2; the driving mechanism is mounted on the mounting plate 1, and the driving end of the driving mechanism is used to drive the main lock tongue switch 3 of the lock body 2 to rotate; the first distance sensor 4 is mounted on the mounting plate 1 and is used to be arranged corresponding to the main lock tongue 19 of the lock body 2 to detect the length of the main lock tongue 19 extending out of the lock body 2; the controller 5 is respectively communicated with the driving mechanism and the first distance sensor 4.

[0037] The driving mechanism drives the main lock tongue switch 3 to rotate, thereby driving the main lock tongue 19 to extend out of the lock body 2. The first distance sensor 4 detects the length of the main lock tongue 19 extending out of the lock body 2, and transmits the data information to the controller 5. The controller 5 determines whether the length standard of the main lock tongue 19 is reached. It can accurately detect whether the main lock tongue 19 is stuck, and then determine the service life of the lock body 2. Compared with the prior art, which can only determine whether the main lock tongue 19 extends out of the lock body 2 but cannot determine whether the length of the extension of the lock body 2 meets the standard, the solution of the present application has higher accuracy in detecting the life of the lock body 2.

[0038] The multifunctional lock body quality and life detection device provided in the present application can detect the oblique lock tongue 18, the main lock tongue 19 and the inductive lock tongue 20, and detect the quality and service life of the lock body 2.

[0039] In a specific embodiment, Figure 3As shown, the adjusting plate 21 is also included. The adjusting plate 21 is provided with a long hole 22. The long hole 22 is arranged along the extension direction of the main lock tongue 19. The mounting plate 1 is provided with a threaded hole corresponding to the long hole 22. The screw 26 passes through the long hole 22 and is screwed with the threaded hole to fix the adjusting plate 21 on the mounting plate 1. The first distance sensor 4 is installed on the adjusting plate 21. By adjusting the corresponding positions of the threaded hole and the long hole 22, the distance between the first distance sensor 4 and the main lock tongue 19 is adjusted to detect the main lock tongue 19 on different lock bodies 2.

[0040] It should be noted that the number of main lock tongues 19 provided on different lock bodies 2 is different, and a plurality of first distance sensors 4 can be provided, and correspond one to one with the plurality of main lock tongues 19 .

[0041] In a more preferred embodiment, an alarm is installed on the mounting plate 1, and the alarm is communicated with the controller 5. When the first distance sensor 4 detects that the extended length of the main lock tongue 19 does not meet the requirement, the signal is transmitted to the controller 5. The controller 5 controls the alarm to sound an alarm to remind the staff that the main lock tongue 19 is damaged.

[0042] In one embodiment, Figure 1 and Figure 2 As shown, it also includes:

[0043] A first cylinder 6 is mounted on the mounting plate 1, and a piston rod of the first cylinder 6 is arranged corresponding to the oblique lock tongue 18 of the lock body 2;

[0044] A second cylinder 7 is mounted on the mounting plate 1, and a piston rod of the second cylinder 7 is arranged corresponding to the induction lock tongue 20 of the lock body 2;

[0045] The first cylinder 6 and the second cylinder 7 are respectively connected to the controller 5 for communication.

[0046] The second cylinder 7 pushes the induction lock tongue 20 and pushes it into the lock body 2. The induction element receives the induction signal and controls the induction motor to rotate. The limit plate moves away from the limit groove, so that the oblique lock tongue 18 can be telescopically moved. The first cylinder 6 pushes the oblique lock tongue 18 to move and can push the oblique lock tongue 18 into the lock body 2, which proves that the oblique lock tongue 18, the induction lock tongue 20 and the induction motor are working normally. The first cylinder 6 and the second cylinder 7 work together to detect the oblique lock tongue 18, the induction lock tongue 20 and the induction motor.

[0047] In one embodiment, Figure 2 As shown, it also includes a cylinder positioning plate 8, which is provided with a first connecting section and a second connecting section. The first connecting section is provided with a connecting hole 9, and the mounting plate 1 is provided with a threaded fixing hole corresponding to the connecting hole 9. The adjusting bolt 10 passes through the connecting hole 9 and is screwed to the threaded fixing hole, and the first cylinder 6 and the second cylinder 7 are both connected to the second connecting section.

[0048] In one embodiment, Figure 2 As shown, the connecting hole 9 is a waist-shaped hole, and the connecting hole 9 is arranged along the telescopic direction of the oblique lock tongue 18 to adjust the distance between the cylinder positioning plate 8 and the lock body 2. The adjusting bolt 10 passes through the connecting hole 9 and is connected to the threaded fixing hole. Before the first connecting section is locked with the mounting plate 1, the adjusting bolt 10 adjusts the distance between the connecting hole 9 and the threaded fixing hole, thereby adjusting the distance between the first gas rod and the second cylinder 7 and the oblique lock tongue 18 and the induction lock tongue 20, respectively, so that different lock bodies 2 can be applied.

[0049] It needs to be further explained that if Figure 2 As shown, the positioning plate is an L-shaped plate, the first connecting section is the horizontal plate of the L-shaped plate, and the second connecting section is the longitudinal plate of the L-shaped plate. Two through holes are provided on the longitudinal plate, and the cylinder barrels of the first cylinder 6 and the second cylinder 7 are fixedly connected to the two through holes respectively.

[0050] In one embodiment, Figure 4 As shown, it also includes a positioning member 11, which is used to connect with the lock body 2. A positioning hole is opened on the positioning member 11, and a mounting hole 12 is opened on the mounting plate 1 corresponding to the positioning hole. A positioning bolt 13 passes through the positioning hole and the mounting hole 12 in sequence and is connected with the positioning nut.

[0051] It needs to be explained that the positioning member 11 is a positioning plate.

[0052] In one embodiment, Figure 4 As shown, the mounting hole 12 is an oblong hole, and the mounting hole 12 is arranged along the extension direction of the vertical oblique lock tongue 18. The position of the lock body 2 is adjusted so that the first cylinder 6 and the second cylinder 7 correspond to the oblique lock tongue 18 and the inductive lock tongue 20 respectively. The positioning bolt 13 passes through the positioning hole and the mounting hole 12 and is connected with the positioning nut. Before the positioning bolt 13 and the positioning nut lock the positioning member 11 on the mounting plate 1, the position of the positioning member 11 is adjusted along the extension direction of the vertical oblique lock tongue 18 so that the first cylinder 6 and the second cylinder 7 are aligned with the oblique lock tongue 18 and the inductive lock tongue 20 respectively.

[0053] In one embodiment, Figure 1 As shown, a locking member 14 is also included. The locking member 14 is installed on the mounting plate 1 . The locking member 14 is used to lock the lock body 2 and the mounting plate 1 .

[0054] It is further explained that the locking member 14 includes a U-shaped plate, a locking wrench and a U-shaped rod. The top plate of the U-shaped plate is fixed on the mounting plate 1, and the two ends of the U-shaped rod are rotatably connected to the two side plates of the U-shaped plate. The locking wrench is rotatably connected to the two side plates of the U-shaped plate. A connecting column 25 is fixedly connected to the lock body 2, and the U-shaped rod is sleeved on the connecting column 25. When the locking wrench is pulled, the locking wrench abuts against the U-shaped rod, so that the U-shaped rod is pressed against the lock body 2.

[0055] As further explained, the locking member 14 may be implemented as an adjustable clamp 304 .

[0056] In one embodiment, Figure 1 As shown, two second distance sensors 15 are also included. The second distance sensors 15 are mounted on the mounting plate 1 corresponding to the top and bottom hooks 16 of the lock body 2 to detect the length of the top and bottom hooks 16 of the lock body 2 extending out of the lock body 2. The two second distance sensors 15 are respectively connected to the controller 5 for communication. The main lock tongue switch 3 can simultaneously drive the top and bottom hooks 16 to extend and retract. The two second distance sensors 15 respectively detect the length of the top and bottom hooks 16 extending out of the lock body 2. When the extended length is different from the set length, the alarm sounds an alarm.

[0057] Specifically, the first distance sensor 4 and the second distance sensor 15 may be ultrasonic distance measuring sensors, laser distance measuring sensors, infrared distance measuring sensors and radar sensors.

[0058] In one embodiment, Figure 1 As shown, a counterweight 17 is also included, and the counterweight 17 is connected to the top and bottom hooks 16 of the lock body 2 to simulate a real unlocking environment.

[0059] It is further explained that the top and bottom hooks 16 are lock tongues installed on the top, bottom and edge of the door to enhance the anti-theft performance and increase the difficulty of prying the door.

[0060] In one embodiment, the driving mechanism is a first motor, which is mounted on the mounting plate 1 and is transmission-connected to the main bolt switch 3 via a transmission assembly. The first motor is communication-connected to the controller 5 .

[0061] The first motor drives the main lock tongue 19 to rotate, thereby controlling the extension and retraction of the main lock tongue 19 and detecting the main lock tongue 19; the second motor drives the handle to rotate, thereby controlling the extension and retraction of the oblique lock tongue 18 and detecting the oblique lock tongue 18. The controller 5 drives the main lock tongue switch 3 and the handle to rotate respectively through the first motor and the second motor, thereby improving the degree of automation.

[0062] Further explanation is that, Figure 5 As shown, a wheel disc 23 is mounted on the output shaft of the first motor, and a connecting column 25 is fixed to the edge of the wheel disc 23. The connecting column 25 is rotationally connected to a connecting rod 24, and the other end of the connecting rod 24 is rotationally connected to a main lock tongue switch 3. The wheel disc 23 rotates, and the main lock tongue switch 3 is driven to rotate reciprocally through the connecting rod 24.

[0063] It is further explained that a second motor is also included, and a pulley is installed on the output shaft of the second motor. The pulley is connected to the rotating shaft of the handle through a belt, and the second motor drives the rotating shaft of the handle to rotate reciprocatingly.

[0064] Below is an embodiment, combined with Figures 1 to 5A comprehensive description of all the above schemes is given.

[0065] The lock body 2 is mounted on the mounting plate 1, and the positioning bolt 13 passes through the positioning hole and the mounting hole 12 to be connected with the positioning nut. Before the positioning bolt 13 and the positioning nut lock the positioning member 11 on the mounting plate 1, the position of the positioning member 11 is adjusted along the extension direction of the vertical oblique lock tongue 18 so that the first cylinder 6 and the second cylinder 7 are aligned with the oblique lock tongue 18 and the inductive lock tongue 20 respectively; then the locking wrench is pulled, and the locking wrench abuts against the U-shaped rod so that the U-shaped rod is pressed against the lock body 2; the adjusting bolt 10 passes through the connecting hole 9 and is connected with the threaded fixing hole. Before the adjusting bolt 10 is locked with the first connecting section and the mounting plate 1, the connecting hole 9 is adjusted to the connecting hole 9 and the inductive lock tongue 20. The distance between the threaded fixing holes is adjusted, and then the distance between the first gas rod and the second cylinder 7 and the oblique lock tongue 18 and the induction lock tongue 20 are adjusted; the counterweight block is connected to the top and bottom hooks 16 to simulate the real unlocking environment; the first motor is turned on, and the first motor drives the wheel 23 to rotate, and the wheel 23 drives the connecting rod 24 to reciprocate, and the main lock tongue switch 3 is driven to reciprocate through the connecting rod 24, and the main lock tongue 19 is driven to telescopically move. The first distance sensor 4 detects whether the extended length of the main lock tongue 19 meets the preset value. When it does not meet the preset value, it means that the main lock tongue 19 may be damaged inside, and the alarm sounds, prompting the staff to check.

[0066] The second motor is turned on, and the second motor drives the pulley to rotate. The pulley is connected to the rotating shaft of the handle through a belt, and drives the rotating shaft of the handle to rotate back and forth, and drives the oblique locking tongue 18 to telescopically move.

[0067] Turn off the second motor, and the second cylinder 7 pushes the induction lock tongue 20 into the lock body 2. The induction element receives the induction signal, controls the induction motor to rotate, and the limit plate moves away from the limit groove, so that the oblique lock tongue 18 can be telescopically moved. The first cylinder 6 pushes the oblique lock tongue 18 to move and can push the oblique lock tongue 18 into the lock body 2, which proves that the oblique lock tongue 18, the induction lock tongue 20 and the induction motor are working normally. The first cylinder 6 and the second cylinder 7 work together to detect the oblique lock tongue 18, the induction lock tongue 20 and the induction motor.

[0068] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations are all within the scope defined by the attached present application.
