DETAILED DESCRIPTION
[0016] In order to better understand the above technical solution, Figure 1-8 And specific implementation methods are used to describe the above technical solutions in detail.
[0017] refer to Figure 1 , Figure 2 and Figure 8 The present application discloses a wear-resistant die-cast luggage lock detection device, comprising a mounting base 1, a housing 11, a lock fixture 2 and a detection mechanism 3. The housing 11 is fixedly mounted on the upper end surface of the mounting base 1 and close to the center. The lock fixture 2 is mounted on the upper end surface of the mounting base 1 and close to the edge, and the lock fixture 2 is mounted on the upper end surface of the mounting base 1 and close to the housing 11. The detection mechanism 3 is mounted inside the housing 11 and is used to detect the stability of the connection between the luggage lock hook and the reciprocating spring.
[0018] Among them, the lock clamp 2 includes a slider 21 and a butt plate 24. The slider 21 is installed on the upper end surface of the mounting seat 1 and close to the edge. A slide groove 23 is provided on the upper end surface of the mounting seat 1 and close to the slider 21, and the slider 21 slides in the slide groove 23. A snap-in groove 22 for installing the luggage lock to be detected is provided on the upper end surface of the slider 21 and close to the edge. The butt plate 24 is installed on the upper end surface of the slider 21 and close to the snap-in groove 22. A spring is provided on one side of the butt plate 24, and the displacement of the butt plate 24 inside the snap-in groove 22 is achieved by the spring, thereby adjusting the opening size of the snap-in groove 22 so that the luggage lock can be smoothly embedded in the snap-in groove 22. The butt plate 24 is used to abut against the outer side wall of the luggage lock, thereby fixing the luggage lock in the snap-in groove 22 on the upper end surface of the slider 21.
[0019] When installing the luggage lock to be tested, the slider 21 is pulled out from the mounting seat 1, and the slider 21 will slide in the slide groove 23, thereby realizing the translation of the slider 21, and then the abutment plate 24 is pulled, and the spring on one side of the abutment plate 24 is used to realize the displacement of the abutment plate 24 inside the clamping groove 22, and the luggage lock is embedded in the clamping groove 22. After the abutment plate 24 is released, the spring pushes the abutment plate 24 to the position of the luggage lock, and the abutment plate 24 abuts against the outer wall of the luggage lock to complete the fixation of the luggage lock, and finally the slider 21 is pushed back to the original position, waiting for the detection mechanism 3 to detect the luggage lock.
[0020] refer to Figures 2 to 5 The detection mechanism 3 includes a motor 31, a drive assembly 32 and a propulsion assembly 4. The motor 31 is fixedly mounted on a mounting bracket on the upper end surface of the mounting seat 1 and close to the housing 11. The drive assembly 32 is mounted inside the housing 11 and close to the motor 31. The propulsion assembly 4 is mounted inside the housing 11 and close to the drive assembly 32.
[0021] The driving assembly 32 includes an incomplete gear 321, a first rack 322, a first telescopic spring 323, a second rack 324, a third rack 325, a second telescopic spring 326 and a connecting member 327. The incomplete gear 321 is fixedly mounted at the output end of the motor 31, and the incomplete gear 321 is driven by the output end of the motor 31. The first rack 322 is mounted inside the housing 11 and close to the incomplete gear 321, and the first rack 322 can be meshed and connected with the teeth on the incomplete gear 321. A slide rail is provided on the side of the first rack 322 away from the incomplete gear 321, and a protrusion used in conjunction with the slide rail on the first rack 322 is installed on the inner side wall of the housing 11 and close to the first rack 322. The protrusion can slide in the slide rail, thereby causing the first rack 322 to translate on the inner side wall of the housing 11. The first telescopic spring 323 is fixedly mounted on one end of the first rack 322, and one end of the first telescopic spring 323 is fixedly connected to the first rack 322, and the other end of the first telescopic spring 323 is fixedly connected to the inner side wall of the housing 11. The second rack 324 is fixedly mounted on one end of the first rack 322 away from the first telescopic spring 323. A slide rail is provided on the side surface of the second rack 324 close to the inner side wall of the housing 11, so that the second rack 324 can translate on a horizontal plane. The propulsion assembly 4 is installed inside the housing 11 and close to the second rack 324. The third rack 325 is installed inside the housing 11 and close to the incomplete gear 321, and a slide rail is also provided on the side of the third rack 325 away from the incomplete gear 321, and a protrusion used in conjunction with the slide rail on the third rack 325 is installed on the inner side wall of the housing 11 and close to the third rack 325. The protrusion can also slide in the slide rail, thereby allowing the third rack 325 to translate on the inner side wall of the housing 11. The second telescopic spring 326 is fixedly mounted on one end of the third rack 325, one end of the second telescopic spring 326 is fixedly connected to the third rack 325, and the other end of the second telescopic spring 326 is fixedly connected to the inner wall of the housing 11. The connecting member 327 is fixedly mounted on one end of the third rack 325 away from the second telescopic spring 326, and the position where the connecting member 327 is connected to the third rack 325 is set as a telescopic structure, and the distance between the connecting member 327 and the third rack 325 is adjusted by the telescopic structure. The connecting member 327 is used to connect the push-twist of the luggage lock.
[0022] The propulsion assembly 4 includes a driving gear 41, a balance wheel 42, a displacement member 43 and a return portion 44. The driving gear 41 is rotatably mounted inside the housing 11 and close to the second rack 324. The driving gear 41 is located below the second rack 324 and is meshed with the second rack 324. The balance wheel 42 is fixedly mounted on one side of the driving gear 41. The balance wheel 42 is configured as a cam. The balance wheel 42 is located outside the housing 11 and rotates synchronously with the driving gear 41. The displacement member 43 is mounted outside the housing 11 and close to the balance wheel 42. The return portion 44 is mounted on the outer wall of the housing 11 and close to the displacement member 43.
[0023] After the luggage lock to be detected is fixed, the motor 31 is started, and the output shaft of the motor 31 rotates to drive the incomplete gear 321 to rotate. The incomplete gear 321 rotates continuously to complete the locking and unlocking actions of the luggage lock.
[0024] Locking stage: the incomplete gear 321 rotates, and the teeth on the outside of the incomplete gear 321 will first mesh with the first rack 322, thereby pushing the first rack 322 to translate in the direction of the second rack 324. At this time, the first telescopic spring 323 will be stretched, and the elastic potential energy of the first telescopic spring 323 will increase. During the displacement process, the second rack 324 will drive the driving gear 41 to rotate by meshing with the driving gear 41, and the balance wheel 42 will rotate by the rotation of the driving gear 41. The rotation angle of the balance wheel 42 depends on the displacement of the second rack 324, and the rotation angle of the balance wheel 42 is ninety degrees. When the balance wheel 42 rotates, the outer wall of the balance wheel 42 squeezes the displacement member 43, causing the displacement member 43 to move downward in the vertical direction. As the balance wheel 42 rotates, the displacement member 43 moves toward the position of the luggage lock, thereby inserting the buckle of the luggage lock into the card slot in the luggage lock. When the buckle ring is inserted into the card slot of the luggage lock, it contacts the hook lock, and the buckle ring squeezes the hook lock, so that the reciprocating spring is slightly compressed, so that the buckle ring can be smoothly sleeved on the hook lock, thereby realizing the locking action of the luggage lock; Unlocking stage: the incomplete gear 321 continues to rotate. When the teeth of the incomplete gear 321 are disengaged from the teeth of the first rack 322, the tension on the first telescopic spring 323 disappears. Since the first telescopic spring 323 is in a stretched state, the first telescopic spring 323 will restore its original length, and then the first rack 322 will be pulled by the first telescopic spring 323. The first telescopic spring 323 pulls the first rack 322 in the direction of the first telescopic spring 323, so that the first rack 322 is reset, and then the second rack 324 is reset, and finally the balance wheel 42 is rotated to the original position. At this time, the buckle at the lower end of the plug plate 434 is engaged with the hook lock, and the roller 432 will be out of contact with the balance wheel 42. A gap appears between the roller 432 and the balance wheel 42. As the incomplete gear 321 rotates, the teeth of the incomplete gear 321 rotate to mesh with the teeth of the third rack 325, and the meshing connection between the outer teeth of the incomplete gear 321 and the teeth on the third rack 325 drives the third rack 325 to translate in the direction of the second telescopic spring 326, so that the second telescopic spring 326 is compressed, and the connecting member 327 is displaced in the direction of the second telescopic spring 326. The movement of the connecting member 327 drives the push-twist displacement of the luggage lock, and then pulls the hook lock inside the luggage lock, so that the reciprocating spring is compressed, the hook lock moves, and then the buckle ring is separated from the engagement connection with the hook lock, and the displacement member 43 with the buckle ring installed is reset under the action of the return part 44, so that the luggage lock is unlocked.
[0025] As the incomplete gear 321 continues to rotate, the luggage lock will repeat the locking and unlocking actions, and then test the connection relationship between the hook lock, buckle ring and reciprocating spring. When the luggage lock is difficult to lock, the displacement member 43 is reset in advance; when the luggage lock is difficult to unlock, the displacement member 43 is not reset. Then the rotation time of the incomplete gear 321 is recorded by the counter, and the number of times the luggage lock repeats the locking and unlocking actions is obtained, completing the detection of the luggage lock, and evaluating the stability of the connection relationship between the hook lock and the reciprocating spring of the luggage lock.
[0026] refer to Figure 5 and Figure 6The displacement member 43 includes a displacement bracket 431, a roller 432, a telescopic rod 433 and an insert plate 434. The displacement bracket 431 is installed on the outside of the return part 44. The roller 432 is rotatably installed on the upper end of the displacement bracket 431, and the outer wall of the roller 432 can abut against the outer wall of the balance wheel 42. When the balance wheel 42 rotates, the roller 432 rotates with the rotation of the balance wheel 42, and with the rotation of the balance wheel 42, the roller 432 will drive the displacement bracket 431 to move downward. The telescopic rod 433 is fixedly installed on the lower end of the displacement bracket 431, and the insert plate 434 is fixedly installed on the lower end of the telescopic rod 433. The insert plate 434 adjusts the distance between the insert plate 434 and the displacement through the telescopic rod 433. The insert plate 434 is used to fix the buckle of the luggage lock. The length of the telescopic rod 433 is adjusted according to the specifications of the luggage lock, so that the plug plate 434 can drive the buckle ring to be exactly inserted into the card slot of the luggage lock and buckled with the hook lock, thereby completing the locking work of the luggage lock.
[0027] The outer wall of the roller 432 and the outer wall of the balance wheel 42 are both made of conductive material. When the roller 432 contacts the balance wheel 42, the circuit is closed, and when the roller 432 is separated from the balance wheel 42, the circuit is disconnected. The working state of the detection mechanism 3 is judged by the state of the circuit closure. The time duration of the roller 432 being disconnected from the balance wheel 42 is defined as S, that is, the time duration of the circuit disconnection is S, and the time duration of the incomplete gear 321 just being separated from the meshing with the first rack 322 and just driving the push-twist unlocking is defined as C. If S is less than C, the roller 432 carries the buckle ring to reset in advance, that is, the buckle ring is not smoothly engaged with the hook lock, and it is determined that the connection between the hook lock and the reciprocating spring fails, and the total number of engagements of the hook lock when it fails is recorded; if S is greater than C, the displacement of the push-twist cannot smoothly unlock the hook lock and the buckle ring, that is, the buckle ring is still in the state of being engaged with the hook lock, and it is determined that the connection between the hook lock and the reciprocating spring fails, and the total number of engagements of the hook lock when it fails is recorded.
[0028] The position of the plug plate 434 is adjusted by the telescopic rod 433, so that the buckle at the lower end of the plug plate 434 can be just inserted into the slot of the luggage lock, and the buckle can be just engaged with the hook lock. During the operation of the propulsion assembly 4, the driving gear 41 is pushed by the second rack 324. As the driving gear 41 rotates, the balance wheel 42 rotates, and the protruding part of the balance wheel 42 squeezes the roller 432. The driving roller 432 moves toward the direction of the plug plate 434 while rolling, so that the buckle at the lower end of the plug plate 434 is inserted into the slot of the luggage lock, and then engaged with the hook lock. After the engagement is completed, the incomplete gear 321 continues to rotate, and then resets the balance wheel 42. At this time, the balance wheel 42 will be out of contact with the roller 432. Since the buckle at the lower end of the plug plate 434 is engaged with the hook lock, the roller 432 will not be reset under the action of the return part 44, and the circuit between the roller 432 and the balance wheel 42 is temporarily disconnected. As the incomplete gear 321 rotates, the third rack 325 pulls and twists, so that the reciprocating spring drives the hook lock to unlock the buckle ring. When the hook lock and the buckle ring are unlocked, the buckle ring will be reset under the action of the return part 44. Then, the roller 432 will contact the balance wheel 42 again to close the circuit.
[0029] The state of the hook lock and buckle ring is determined according to the closing time of the circuit between the roller 432 and the balance wheel 42. If S is less than C, the roller 432 carrying the buckle ring is reset in advance, that is, the buckle ring is not smoothly engaged with the hook lock, and the connection between the hook lock and the reciprocating spring is determined to be invalid, and the total number of engagements of the hook lock when it fails is recorded; if S is greater than C, the displacement of the push and twist cannot smoothly unlock the hook lock and the buckle ring, that is, the buckle ring is still in the state of being engaged with the hook lock, and the connection between the hook lock and the reciprocating spring is determined to be invalid, and the total number of engagements of the hook lock when it fails is recorded.
[0030] refer to Figure 5 and Figure 7The return part 44 includes a fixed housing 441, a fixed column 442, a surrounding column 443 and a rope 444. The fixed housing 441 is fixedly mounted on the fixed column 442, and the fixed column 442 is fixedly mounted on the outer wall of the housing 11 and close to the balance wheel 42. The fixed housing 441 is fixedly connected to the housing 11 through the fixed column 442. The surrounding column 443 with a torsion spring is fixedly mounted inside the fixed housing 441 and close to the upper end. The surrounding column 443 is rotatably connected to the fixed housing 441, and the surrounding column 443 can automatically reset after rotation. The two surrounding columns 443 are symmetrically distributed about the displacement bracket 431. The rope 444 is installed inside the fixed housing 441, and one end of the rope 444 is wound around one of the surrounding columns 443, and the other end of the rope 444 is wound around the other surrounding column 443. The middle section of the rope 444 is connected to the displacement bracket 431. A rectangular groove for the displacement bracket 431 to slide is provided on the outer wall of the fixed housing 441, and a slide bar is provided on one side of the displacement bracket 431, one end of which is plugged into the interior of the fixed housing 441. The portion of the displacement bracket 431 plugged into the fixed housing 441 abuts against the middle section of the rope 444, and when the displacement bracket 431 moves downward, the middle section of the rope 444 moves downward with the displacement bracket 431, and the surrounding columns 443 at both ends of the rope 444 rotate synchronously.
[0031] When the balance wheel 42 pushes the displacement bracket 431 to move downward, the part of the displacement bracket 431 inserted into the fixed housing 441 pushes the rope 444, causing the surrounding column 443 connected at both ends of the rope 444 to rotate, thereby increasing the length of the middle section of the rope 444, and the displacement bracket 431 falls smoothly. At this time, the torsion spring inside the surrounding column 443 is compressed. When the buckle at the lower end of the plug plate 434 is engaged with the hook lock of the luggage lock, the displacement bracket 431 does not reset after the balance wheel 42 returns to its position. When the buckle and the hook lock are unlocked, the torsion spring on the surrounding column 443 is reset, and the surrounding column 443 rotates, thereby driving the rope 444 to wrap around the surrounding column 443 again, thereby driving the displacement bracket 431 to move upward, causing the roller 432 to contact the balance wheel 42 again, so that the buckle can automatically reset after unlocking, which is convenient for the next plug-in.
[0032] A detection method based on a wear-resistant die-casting luggage lock detection device comprises the following steps: S1. Debug the test mechanism. According to the structure and specifications of the luggage lock, adjust the position of the plug plate 434 and the connecting member 327 so that the buckle at the lower end of the plug plate 434 can be inserted into the slot of the luggage lock, so that the connecting member 327 can be engaged with the push-twist of the luggage lock, so that the connecting member 327 can drive the push-twist displacement; S2. Install the luggage lock, remove the slider 21 from the mounting seat 1, and then pull the plate 24 on the upper end of the slider 21, insert the luggage lock into the clamping groove 22 provided on the upper end of the slider 21, and then release the plate 24, so that the plate 24 abuts against the outer wall of the luggage lock, fix the luggage lock, and finally reset the slider 21; S3. The luggage lock is locked, the motor 31 is started, and the rotation of the output end of the motor 31 drives the incomplete gear 321 to rotate. When the incomplete gear 321 rotates, the teeth on the surface of the incomplete gear 321 mesh with the first rack 322, driving the second rack 324 to move, and then the driving gear 41 drives the balance wheel 42 to swing, so that the plug plate 434 is displaced in the vertical direction, so that the buckle at the lower end of the plug plate 434 is inserted into the card slot of the luggage lock, and the hook lock is locked.
