Description

Technical Field

[0001] The utility model belongs to the technical field of fatigue testing, and in particular relates to a switch rebound fatigue testing mechanism. Background Art

[0002] As an indispensable part of machinery, switches are the parts that workers come into contact with the most. Take the most common push button switch as an example. In order to ensure the stability of the push button switch, it needs to be subjected to a rebound fatigue test before leaving the factory. The push button switch is pressed at least thousands of times by a machine, and the push button switch still needs to maintain sufficient rebound.

[0003] Since the rebound of the push button switch mainly depends on the spring, it is normal for the rebound height to be lower than the initial height after a long period of high-frequency pressing. The test is mainly for the situation where there is no rebound at all or the rebound is too low. However, most of the rebound fatigue testing institutions currently require staff to take out the push button switches and check them one by one after detecting the push button switches with rebound problems, which results in insufficient detection efficiency.

[0004] To this end, we proposed a switch rebound fatigue testing mechanism to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problems in the prior art and proposes a switch rebound fatigue testing mechanism.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1 As shown, a switch rebound fatigue testing mechanism includes a testing machine 1 and a plurality of button switches 2. A plurality of fixing frames 3 are installed in the testing machine 1, and the plurality of button switches 2 are installed in the plurality of fixing frames 3 respectively. There are many mature solutions in the prior art on how to fix the button switches 2 with the fixing frames 3. In the present application, the fixing method of the button switches 2 does not belong to the innovative part, so it will not be described in detail.

[0021] Reference Figure 2 A motion groove 4 is respectively provided at the top of the opposite side walls on both sides of the fixed frame 3, and a motion block 5 is slidably connected in the motion groove 4. The cross-section of the motion groove 4 is "T"-shaped, and the top of the motion groove 4 is open. The motion block 5 is also "T"-shaped. At the same time, the "T" bottom of the motion groove 4 is also open. Therefore, the connecting rod 6 arranged on the side wall of the motion block 5 can also move with the motion block 5.

[0022] The side walls of the two moving blocks 5 on the opposite sides are respectively fixedly connected with connecting rods 6, and a top plate 7 is fixedly connected between the two connecting rods 6. The bottom wall of the top plate 7 abuts against the top wall of the button switch 2. The top plate 7 is supported by the button switch 2. When the button switch 2 rebounds normally, the top plate 7 can be driven to rise together. The width of the top plate 7 is greater than the width of the button switch 2, and the length of the top plate 7 is also greater than the length of the button switch 2.

[0023] Reference Figure 3 A working cavity is respectively provided on the side walls of the fixed frame 3, and a prompt component is installed in the working cavity, which includes a motion rack 8, a rotating gear 9, a center rod 10 and a prompt plate 11. A through groove 12 is provided at the bottom of the motion groove 4, which is connected to the working cavity. The motion rack 8 is slidably connected to the side wall of the through groove 12. A vertical rod 13 is fixedly provided on the side wall of the motion rack 8, and a vertical groove 14 is provided on the side wall of the through groove 12. The vertical rod 13 is slidably connected to the inner wall of the vertical groove 14. The length of the vertical groove 14 does not exceed the length of the through groove 12. Therefore, when the vertical rod 13 and the motion rack 8 move together with the motion block 5, when the motion block 5 is completely separated from the motion groove 4, the motion rack 8 will fall back into the through groove 12 under the restriction of the vertical groove 14.

[0024] The moving rack 8 is installed at the bottom of the moving block 5, and a magnetic sheet 15 is fixedly installed on the top of the moving rack 8. The moving block 5 is a magnetic metal. The magnetic sheet 15 and the moving block 5 of the magnetic metal attract each other. When the moving block 5 moves, it will drive the moving rack 8 to move together. The rotating gear 9 is rotatably connected to the side wall of the working chamber, and the rotating gear 9 is meshed with the moving rack 8. The side wall of the rotating gear 9 is fixedly connected with a center rod 10, which passes through the side wall of the working chamber and extends out of the fixed frame 3. The prompt plate 11 is fixed on the side wall of the center rod 10 extending out of the fixed frame 3. In the normal state, the prompt plate 11 is in a horizontal state.

[0025] The working principle is as follows: first, place the button switch 2 into the fixed frame 3, and then place the motion block 5 into the motion groove 4. Under the action of gravity, the motion block 5 will slide down along the motion groove 4, and the connecting rod 6 on the side wall of the motion block 5 will drive the top plate 7 to descend together until the top plate 7 is against the button switch 2. At this time, the motion block 5 and the magnetic sheet 15 on the top of the motion rack 8 attract each other. When the testing machine 1 performs a press test on the button switch 2, the top plate 7 will rise and fall together with the button switch 2, and the motion rack 8 that moves with the motion block 5 will drive the rotating gear 9 to rotate, and then drive the center rod 10 and the prompt plate 11 to rotate together. If the button switch 2 loses its rebound ability, the top plate 7 will always be at the lowest height together with the button switch 2. At this time, the prompt plate 11 is in a vertical state, which can remind the staff that there is a problem with the rebound ability of the button switch 2.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
