Description

Technical Field

[0001] The invention relates to the field of anti-theft safety door inspection equipment. Background Art

[0002] The lock handle strength project is an important test item in GB17565-2022 "General Technical Conditions for Anti-theft Security Doors". This test uses a handle strength test to test whether the lock handle can withstand a tensile force of 1600N without being pulled off or damaged. The test method described in the standard applies a 1600N tensile force perpendicular to the door surface to the center of the handle by means of pulley weighting and maintains it for 5 minutes. After the test, check its function to see if it meets the standard requirements.

[0003] The test procedure for the inspection of anti-theft security doors first requires the test door to be installed on a simulated test bench. Because the anti-theft security door being tested is heavy and large in size, it is inconvenient to install. The test procedure requires that after one installation, several inspection items be carried out on the test bench in sequence until the inspection items are completed. The lock handle strength item is one of the inspection items. To inspect the lock handle, a pulling force of 1600N needs to be applied to the lock handle. Since manual force cannot be achieved, a reliable and stable force application device must be available, and the device must also meet the requirements of the lock handle structure, installation direction, and installation position diversity of the anti-theft security door. In order to meet the requirements, the test device has the ability to adjust the force application position, use a diamond spiral force application mechanism to apply force, and a force sensor to measure force. It is installed and used on the original test bench, which meets the test procedure requirements of one installation and can carry out several inspection items.

[0004] The current situation is that GB17565-2022 "General Technical Requirements for Anti-theft Security Doors" has been newly revised and released. The lock handle strength project is a newly added inspection project, and there is no equipment for the handle strength test. The development of this project plays a leading role in the national anti-theft security door testing institutions and production enterprises. The device system is cleverly designed, occupies a small area, and has low equipment manufacturing costs, which meets the requirements of the standard and the needs of the testing institutions. Summary of the invention

[0005] The technical problems to be solved by the present invention are:

[0006] To test the lock handle, it is necessary to apply a pulling force of 1600N to the lock handle. Since manual force cannot be achieved, a reliable and stable force application device is required. In addition, the device must meet the diverse requirements of the lock handle structure, installation direction, installation position direction, etc. of the test anti-theft security door.

[0007] The diamond spiral force-applying mechanism is used to apply force, the force sensor is used to measure force, and it is installed and used on the original test bench. This meets the test procedure requirements for the anti-theft security door to be fixedly installed once, and the requirements for subsequent tests of several inspection items can be carried out.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is: the test device for the strength of the lock handle of the anti-theft security door belongs to the field of inspection equipment. A guide rail (2) is installed on the machine base (1), and a movable machine base (3) is used to achieve lateral movement. The movable machine base (3), the lifting bracket (4) and the lifting rod (9) form a lifting mechanism. A guide wheel (11) is installed on the lateral bracket (10), and the other end is connected to two adjustable lifting frames (12) to achieve longitudinal movement. The frame structure with adjustable position of the device solves the need for a stable force-applying device during the test, and meets the diverse requirements of different structures and different installation positions of the lock handle of the anti-theft security door.

[0009] A diamond force applicator (5) is installed on the mobile base (3), and is adjusted by a double screw rod (6). The steel wire rope (8) is connected to the tension sensor (7), guided by a guide wheel (11), and connected to the door handle fixture (15) on the security anti-theft door (13). The structure of the door handle fixture (15) is that the front clamp (17) and the opening clamp (18) are used to fasten the door handle (14) by four screws (19), and the tension sensor (7) is connected to the steel wire rope (8) through a hanging ring (16) to measure the force. The force applying mechanism adopts a diamond spiral force applying mechanism to apply force through a force sensor, and can be installed and used on the original test bench, meeting the different structures of the lock handle of the anti-theft security door, meeting the requirements of the test procedure for the fixed installation of the anti-theft security door once, and can carry out the subsequent test of several inspection items. It meets the requirements of different structures and installation positions of the lock handle and the security door being fixed once, and then carrying out the subsequent test of several test items.
