As shown in fig. 1 to 4, the hinge life detection device according to an embodiment of the present invention is configured to install a hinge 80 to be tested between a door panel 30 and a rack 10, test the number of times of use of the hinge by testing the number of times of opening and closing the door panel 30, measure the hinge 80 to be tested according to a test standard requirement (for example, 4 ten thousand times), turn off a power supply after the number of times of test required by the test standard is reached, determine whether the quality of the hinge 80 to be tested meets the requirement according to the degree of wear of the hinge 80 to be tested, and if the hinge 80 to be tested is damaged before the number of times of test is reached, end the test in advance.
Referring to fig. 1 to 4, the hinge life detection apparatus according to the embodiment of the present invention includes a rack 10, a control box 20 disposed on the rack 10, a door panel 30 configured to cooperate with the rack 10 to test a hinge 80 to be tested, a pulling rope 40 connected to the door panel 30, a driving assembly 50 connected to the pulling rope 40 and configured to drive the door panel 30 to open and close, and a first sensor assembly disposed on the rack 10 and configured to measure the number of times of opening and closing the door panel 30, where the driving assembly 50 and the first sensor assembly are both connected to the control box 20, and the driving assembly 50 is configured to drive the door panel 30 through the pulling rope 40 to complete a door opening operation and is configured to drive the door panel 30 to close to a preset position so that the door panel 30 can complete a door closing operation through inertia. That is, the door panel 30 completes the door opening action under the action of the pulling force applied by the driving assembly 50 through the pulling rope 40, and the door panel 30 continues to close and completes the door closing action under the action of the inertia force after closing to the preset position under the pushing force applied by the driving assembly 50, that is, the driving assembly 50 stops applying the pushing force to the door panel 30 after pushing the door panel 30 to move to the preset position.
It can be understood that, during the process that the driving assembly 50 drives the door panel 30 to open, in the initial state, the pulling rope 40 is gathered, after the driving assembly 50 passes through a certain stroke, the pulling rope 40 is completely extended between the driving assembly 50 and the door panel 30, and the driving assembly 50 drives the door panel 30 to open to the maximum amplitude through the pulling rope 40. During the process that the driving assembly 50 drives the door panel 30 to close, the traction rope 40 is gathered, and the pushing force exerted by the driving assembly 50 directly acts on the door panel 30.
It can be understood that, the hinge is hinged between two components in the actual use process, for example, between the door panel 30 and the door frame, when the door is closed, only a certain acting force needs to be given to the door panel 30, and after the door panel 30 is closed to a certain angle, the door panel 30 can complete the door closing action under the action of inertia force, therefore, the hinge life detection device of the embodiment of the present invention can ensure that a certain stroke is kept in the closing process of the door panel 30 by arranging the traction rope 40 between the driving assembly 50 and the door panel 30, so that the driving assembly 50 does not apply thrust to the door panel 30, so that the door panel 30 can continue to close and complete the door closing action under the action of inertia force, and the hinge life detection device has the following advantages:

The limiting portion 525 is configured to prevent the rack 522 from being disengaged from the gear 521, so that the rack 522 and the gear 521 are always engaged. The first crank 523 moves a stroke, the rocker 54 swings back and forth, the door panel 30 is opened and closed once, the transmission mode is reliable, and the control is convenient.
It is understood that the shape or position of the limiting portion 525 can be adaptively set according to the moving track of the rack 522.
It should be understood that the transmission mechanism 52 may also have other structures, as long as the purpose of driving the rocker 54 to swing back and forth within the preset stroke range under the driving of the driving motor 51 can be achieved. For example, as shown in fig. 5, the transmission mechanism 52 includes a second crank 526, a second connecting member 527 and a rotating member 528, the second crank 526 is connected to the output end of the driving motor 51, the rotating member 528 is sleeved on the rotating shaft 53, and the diameter of the rotating member 528 is greater than that of the crank, one end of the second connecting member 527 is rotatably connected to the second crank 526, the other end is rotatably connected to the rotating member 528, the second crank 526 rotates with the driving motor 51 to drive the second connecting member 527 to make a circular motion, so as to drive the rotating shaft 53 to switch between clockwise rotation and counterclockwise rotation, the second crank 526 moves one stroke, the rocker 54 swings one time, and the door panel 30 is opened and closed once.
On this basis, the hinge life detection device further comprises a second sensor assembly 70, wherein the second sensor assembly 70 is used for measuring the number of times of the stroke of the first crank 523, generally speaking, the first crank 523 moves one stroke, the rocker 54 swings one time back and forth, and the door panel 30 opens and closes once, so that whether the door panel 30 can not be closed due to the problem of the hinge 80 to be detected or not or whether the first sensor assembly and the second sensor assembly 70 have the failure condition can be judged by checking the measurement data of the first sensor assembly and the measurement data of the second sensor assembly 70.
Illustratively, the second sensor assembly 70 is an infrared counter, and includes an infrared probe 71 and a sensed member 72, the infrared probe 71 is disposed on the frame 10, and the sensed member 72 is disposed on the first crank 523, since the infrared counter is a conventional sensor, the detailed operation thereof is not described herein again.
Further, the hinge life detection apparatus may be provided with an alarm device (not shown), and when the value measured by the first sensor assembly is different from the value measured by the second sensor assembly 70, the alarm device sends an alarm to remind a worker that the hinge life detection apparatus may be abnormal. Therefore, the hinge service life detection equipment can be prevented from doing useless work without being watched by workers all the time.
Referring to fig. 1 to 4, in some embodiments, the rack 10 includes a base 11, a support leg 12 disposed at the bottom of the base 11, and a column 13 disposed on the base 11, the door panel 30 is hinged to the column 13 through a hinge 80 to be tested, the control box 20 is fixed on the column 13, the first sensor assembly is fixed on the column 13 through a bracket, the transmission mechanism 52 is disposed below the base 11, the driving motor 51 is disposed on the base 11, an output shaft of the driving motor 51 passes through the base 11 and is connected to the transmission mechanism 52, the rotating shaft 53 is rotatably mounted in the column 13, a first end of the rotating shaft 53 extends out of the column 13 and is connected to the transmission mechanism 52, and a second end of the rotating shaft 53 extends out of the column 13 and is connected to the rocker 54.

Referring to fig. 2 and 3, in some embodiments, the first sensor assembly employs a proximity switch 60 and a counter (not shown) to count the number of times the door panel 30 is closed. Proximity switch 60 includes sensing head 61 and is responded to the portion 62 by the sensing, sensing head 61 is fixed on frame 10, sensing head 61 is used for responding to by sensing portion 62 in the response scope, it installs on frame 10 to be rotated by sensing portion 62, can swing to the sensing scope after being responded to portion 62 by door plant 30 touching, when door plant 30 closes, door plant 30 touches sensing head 61 and makes to be responded to portion 62 swing to can be sensed by sensing head 61, sensing head 61 senses sensing head 61 transmitting signal behind being responded to portion 62, the counter increases a count value.
