Description

Technical Field

[0001] The utility model belongs to the technical field of hook lock force detection, in particular to a detection device for detecting the relationship between the hook lock opening and closing forces and the pre-tightening force. Background Art

[0002] The hook lock is a common lock body structure. It is mainly used for locking various fairings and maintenance doors on aircraft because of its simple structure, affordable price, and easy installation and maintenance. The preload force of the hook assembly is an important parameter that reflects the performance of the hook lock. The preload force of the hook lock directly affects the unlocking force and locking force of the hook lock. When the preload force increases, the deformation of the hook lock, locking mechanism, lock plate, handle and other parts of the hook lock will increase when opening and closing, and the required opening and closing locking force will be greater. When the preload force exceeds a certain value, the opening and closing locking force will be very large, which does not meet the requirements of ergonomics, and the parts of the hook lock will undergo certain plastic deformation, affecting the life and safety of the hook assembly.

[0003] Based on the above description, it is necessary to design a special detection device to study the relationship between preload and opening and closing forces. By studying the relationship curve between preload and opening and closing forces, it helps to stipulate reasonable preload requirements, so that the parts of the hook lock are in the elastic deformation stage when opening and closing, ensuring the service life and reliability of the hook lock.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0105] The detection device for detecting the relationship between the hook locking force, the locking force and the pre-tightening force described in the utility model, when in use:

[0106] Fix the detection device to the workbench, adjust the pre-tightening force of the hook lock 3, and hook the hook end of the hook lock 3 on the first connecting component 41; press the opening component 33 to put the hook lock 3 in a pre-opening state; use the push-pull dynamometer 6 to flip the hook lock cover 36 to the maximum opening position, and record the maximum hook lock pulling cover force (unlocking force) during the unlocking process; use the push-pull dynamometer 6 to press the hook lock cover 36 until it closes, and record the maximum hook lock pressing cover force (locking force) during the locking process; repeat the above operation at least 3 times, and record the unlocking force and locking force of each operation.

[0107] When the hook lock 3 is in the pre-tightening state, after pressing the opening component 33, the hook lock 3 is in the pre-opening state (not fully opened), and the hook lock cover 36 needs to be pulled to be fully opened; as the pre-tightening force increases, the unlocking force of pulling the hook lock cover 36 to unlock will increase significantly, and the locking force of closing the hook lock cover 36 will also increase. A detection device provided in the present application can detect the corresponding unlocking force and locking force information under the condition of calibrated (pre-set) pre-tightening force.

[0108] Please refer to the attached Figure 6 After many tests, it can be learned that: as the preload force increases, the corresponding unlocking force and locking force will also increase, and they are roughly linearly related.

[0109] Please refer to the attached Figure 7 and attached Figure 8 In a specific implementation of this embodiment, the hook lock 3 includes:

[0110] A lock hook assembly 35, wherein the lock hook assembly 35 is divided into a hook end 31 and a non-hook end 32 according to whether a hook operation can be performed;

[0112] The opening component 33 is at least partially disposed in the hook lock cover 36 to control the opening or closing of the hook lock cover 36.

[0113] Please refer to the attached Figure 2 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 7 and attached Figure 8 In a specific implementation of this embodiment, the opening assembly 33 includes a trigger 331, and the trigger 331 is arranged on the hook lock cover 36. One end of the trigger 331 is connected to a partition (not shown in the figure) through a rivet 332, and the partition is arranged between the trigger 331 and the inner wall of the hook lock cover 36. The outer side of the rivet 332 is sleeved with a bushing, and the outer side of the bushing is sleeved with a torsion spring 333.

[0114] The two partitions are assembled on the outer circle of the bushing, and finally assembled on the hook lock cover 36 through rivets 332. Ensure that the upper surface of the trigger 331 is flush with the upper surface of the hook lock cover 36, the trigger 331 moves flexibly, and the rivet 332 is riveted flat by a rotary riveting machine.

[0115] When unlocking, the trigger 331 is pressed, and the hook lock cover 36 opens to a certain angle. At this time, the lock hook assembly 35 is still in a locked state (pre-opening state). (Through the push-pull force gauge 6), the lock cover end of the hook lock cover 36 is pulled up, and the hook lock 3 passes the locking point position and is fully opened.

[0116] The detection device provided in this application is used to detect the relationship between the opening and locking force and the pre-tightening force of the hook lock. The corresponding opening and locking force data under the condition of calibrated (pre-set) pre-tightening force can be detected to provide data support for adjusting the installed pre-tightening force, which not only improves the installation, adjustment and maintenance efficiency of the hook lock, but also ensures that the hook lock has more reliable performance and a longer service life.
