Detailed Embodiments

[0021] The technical solution of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0022] An embodiment of the present application discloses a detection device for the quality of a door lock. Refer to Figure 1 , the detection device for the quality of a door lock includes a detection table 10, a collision component 20, a support component 30, and a driving component 40. The detection table 10 is used to fix the door lock to be detected. The collision component 20 is movably arranged above the door lock to be detected, and the collision component 20 can be used to perform collision detection on the door lock. The support component 30 is fixedly connected to the side of the detection table 10, and the upper end of the support component 30 is used to support and install the driving component 40 and cooperate with the driving component 40 to drive the collision component 20. The driving component 40 is used to drive the movement of the collision component 20 so that the collision component 20 can perform impact fatigue detection on the door lock.

[0023] Refer to Figure 5 , a placement seat 11 for installing and placing the door lock to be detected is formed at the bottom of the detection table 10. Before the door lock is detected, auxiliary accessories such as jigs can be used to fix the door lock on the placement seat 11. The detection table 10 is formed with a guide groove 12 that slidably cooperates with the collision block 21 in the collision component 20 along its height direction, and the lower end of the guide groove 12 opens towards the fixed door lock.

[0024] Refer to Figure 2 , the collision component 20 includes a collision block 21, a sling 25, a deflection roller 26, and two convex columns 27. The collision block 21 can be made of a solid metal block, and two lifting lugs 22 are formed at the top of the collision block 21. An insertion shaft 23 connected and fixed to the two lifting lugs 22 can be inserted between the two lifting lugs 22. A collar 24 sleeved on the insertion shaft 23 is formed at the lower end of the sling 25, so that the lower end of the sling 25 can hoist the collision block 21. The upper end of the sling 25 is fixedly connected to the outer wall of the deflection roller 26, and the deflection roller 26 is rotatably connected to the support component 30, so that the sling 25 can be coiled around the outside of the deflection roller 26 or released outside the deflection roller 26. The sling 25 can pass through the guide groove 12 when coiling or releasing. The two convex columns 27 are both formed on the outer end face of the deflection roller 26, and the two convex columns 27 and the center of the deflection roller 26 are on the same horizontal line. The two convex columns 27 can cooperate with the support component 30 and the driving component 40 to drive the deflection and swing of the deflection roller 26.

[0025] Refer to Figure 3, the bracket assembly 30 includes a connecting bracket 31, a hood 32, a positioning disk 33, an arc-shaped wall 34, and two bumps 35. One side of the connecting bracket 31 facing the inspection table 10 is fixedly connected to the inspection table 10, and the upper end of the connecting bracket 31 is fixedly connected to the hood 32 and the positioning disk 33 respectively. The hood 32 is used to install the motor 41 and the transmission mechanism in the driving assembly 40. The deflection roller 26 is rotatably connected to the positioning disk 33. The arc-shaped wall 34 is formed on the outer edge of one side of the positioning disk 33 facing away from the connecting bracket 31. The deflection roller 26 is deflected and arranged inside the arc-shaped wall 34 with a gap between the deflection roller 26 and the inner wall of the arc-shaped wall 34. The width of the arc-shaped wall 34 is equal to the width of the deflection roller 26, and the deflection roller 26 can move inside the arc-shaped wall 34 when it swings deflectingly. The cross-section of the arc-shaped wall 34 is set to a semi-circular arc. The two bumps 35 are respectively formed at both ends of the side of the arc-shaped wall 34 facing away from the positioning disk 33, and the bumps 35 protrude a certain length towards the side of the arc-shaped wall 34 facing away from the positioning disk 33. The bumps 35 are connected to the outer wall of the arc-shaped wall 34 by an inclined surface, and the bumps 35 are used to cooperate with the adjustment of the position state of the lever 47 in the driving assembly 40.

[0026] Refer to Figure 4 , the driving assembly 40 includes a motor 41, a transmission mechanism, and a lever 47. The motor 41 is installed in the hood 32 of the bracket assembly 30. One end of the transmission mechanism is connected to the hood 32 in the bracket assembly 30, and the other end of the transmission mechanism is fixedly connected to the lever 47. The motor 41 can drive the transmission mechanism to adjust the position state of the lever 47 under the guiding cooperation of the bracket assembly 30, and the lever 47 swings and deflects the deflection roller 26 cyclically in cooperation with the convex post 27, so that the collision block 21 can repeatedly perform collision detection on the door lock to be detected.

[0027] In this embodiment, the transmission mechanism includes a thick gear 42, a thin gear 43, a rotating shaft 44, an annular disk 45, and a spring 46. The thick gear 42 is sleeved on the output end of the motor 41 and fixedly connected thereto. The thin gear 43 meshes with the thick gear 42. The thin gear 43 is sleeved on the rotating shaft 44 and fixedly connected thereto. The thickness of the thin gear 43 is less than the thickness of the thick gear 42, so that the thin gear 43 can maintain meshing with the thick gear 42 when it moves horizontally along with the rotating shaft 44. The rotating shaft 44 passes through the positioning disk 33 and the deflection roller 26 and is fixedly connected to the lever 47. The positioning disk 33 can support the rotation of the rotating shaft 44 and guide the horizontal movement of the rotating shaft 44. The annular disk 45 is sleeved on the middle section of the rotating shaft 44 and fixedly connected thereto. The spring 46 is sleeved on the outside of the rotating shaft 44, and one end of the spring 46 is fixedly connected to the positioning disk 33 and the other end is in contact with the annular disk 45. When the spring 46 deforms towards the positioning disk 33, it can drive the annular disk 45 and the rotating shaft 44 to move horizontally therewith.

[0028] When the output end of the motor 41 drives the thick gear 42 to rotate, the meshing and cooperation between the thick gear 42 and the thin gear 43 can make the thin gear 43 drive the rotating shaft 44 and the lever 47 to rotate accordingly. When the lever 47 rotates between the two convex columns 27 and contacts one of the convex columns 27, it can push the convex column 27 and cause the deflection roller 26 to deflect accordingly, thereby causing the deflection roller 26 to wind up the sling 25 and causing the collision block 21 to rise. When the lever 47 continues to rotate and contacts the convex block 35, the convex block 35 can push the lever 47 to move horizontally and compress the spring 46. At this time, the lever 47 can be separated from the convex column 27, and the collision block 21 can fall under the action of gravity and impact the door lock. During one rotation of the lever 47, the lever 47 can adjust the contact state between the lever 47 and the convex column 27 twice by using the convex block 35, and cause the collision block 21 to repeat the impact process twice.

[0029] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
