[0034] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0035] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] refer to Figures 1 to 7 This utility model provides a tooling fixture for a buffer hinge 7, including a fixing component 1, a first trigger switch 2, a second trigger switch 3, a timer 4, and a base plate 5. (See reference) Figure 1The fixing component 1 is used to fix one end of the hinge 7. The first trigger switch 2 is located outside the hinge 7, and when the hinge 7 is opened to its maximum angle, its outer side is in contact with the first trigger switch 2. It should be noted that the outer side of the hinge 7 refers to the opposite side of the hinge 7's rotation direction. When the hinge 7 rotates, it will rotate in the opposite direction to the first trigger switch 2. The second trigger switch 3 is located within the rotation range of the hinge 7, and the hinge 7 touches the second trigger switch 3 when it rotates to a predetermined position. It should be noted that the rotation range of the hinge 7 refers to the range that the hinge 7 will pass through when it rotates, that is, the side of the second trigger switch 3 that the hinge 7 will rotate from one side to the other side of the second trigger switch 3 during the rotation process. Both the first trigger switch 2 and the second trigger switch 3 are electrically connected to the timer 4. When the hinge 7 rotates, the timer 4 starts timing when it touches the second trigger switch 3, and stops timing when it touches the first trigger switch 2. This can be used to record the buffer time of the hinge 7. The fixing component 1, the first trigger switch 2, the second trigger switch 3, and the timer 4 are all fixed on the base plate 5. It should be noted that, in this application, the position of the first trigger switch 2 refers to the position of the point where the first trigger head 22 contacts the hinge 7, and the position of the second trigger switch 3 refers to the position of the point where the second trigger switch 3 contacts the hinge 7.

[0038] refer to Figure 2 Taking a 180° buffer hinge as an example, during operation, the first leaf of the hinge is fixed using the fixing component 1. The second leaf is then bent to a 90° position, and a force is applied to the second leaf to make it rotate. When the second leaf collides with the second trigger switch 3, the timer 4 starts timing. When the second leaf triggers the first trigger switch 2, the timer 4 stops timing. The buffer time of the hinge can then be determined. This method offers high detection efficiency and improves automatic detection capabilities.

[0039] refer to Figure 3 and Figure 4 In a preferred embodiment, the fixing component 1 includes a fixing plate 11 and a clamping member 12. The fixing plate 11 includes a horizontal plate 111 and a vertical plate 112, which are arranged vertically. One end of the vertical plate 112 extends toward the clamping member 12. The hinge 7 includes two blades that are rotatably connected to each other. In use, one of the blades is in close contact with the horizontal plate 111 of the clamping plate, and the end of the blade abuts against the vertical plate 112, which can determine the specific position of the blade. The clamping member 12 includes a clamping rod 121 and a clamping switch 122. The clamping switch 122 can move the clamping rod 121 in a direction perpendicular to the horizontal plate 111, thereby clamping or loosening the hinge 7 near the horizontal plate 111. During testing, the clamping switch 122 is used to remove the clamping rod 121 from the clamping plate, the hinge 7 is placed on the clamping member 12, and then the clamping rod 121 is used to clamp the hinge 7 to fix its position.

[0040] In a further preferred embodiment, the clamping member 12 further includes a clamping base 123 and a connecting member 124. The clamping base 123 is provided with a first fixing part 1231 and a second fixing part 1232. The clamping switch 122 includes a connecting part and a handle part, the included angle between the connecting part and the handle part is less than 180°. One end of the connecting part is rotatably connected to the first fixing part, and the second end of the connecting part is rotatably connected to the first end of the connecting member 124. The second fixing part is provided with a guide hole, and the first end of the clamping rod 121 passes through the guide hole and is rotatably connected to the second end of the connecting member 124. Rotating the handle part can cause the clamping rod 121 to clamp or loosen the hinge 7. The second end of the clamping rod 121 is fixedly connected to a clamping head 125. The length of the clamping head 125 is adjustable, and adjusting the length of the clamping head can adapt it to different types of hinges 7.

[0041] refer to Figure 5 In a preferred embodiment, the first trigger switch 2 includes a first sensor 21, a first trigger head 22, and a first handle 23. The first trigger head 22 is fixed to the first sensor 21, and the first end of the first sensor 21 is rotatably connected to the base plate 5. The handle is fixed to the second end of the first sensor 21. Specifically, a protective shell is provided on the upper part of the first trigger switch 2, and the handle passes through a sliding hole in the protective shell. Changing the position by moving the first handle is to retract the first trigger head 22 for protection, preventing bumps during clamping. The first trigger head 22 needs to be released during testing, and the contact position of the first trigger head can be adjusted by an adjusting member.

[0042] refer to Figure 6 In a preferred embodiment, the second trigger switch 3 includes a second sensor 31 and a second trigger head 32. The second trigger head 32 is fixed on the second sensor 31. One end of the second sensor 31 is rotatably connected to the base plate 5. The second end of the second sensor 31 is provided with a second guide block. The base plate 5 is provided with a second guide groove 512. The position of the second trigger head 32 can be changed by rotating the second trigger switch 3.

[0043] In a further preferred embodiment, a protective cover 33 is fixedly connected to the base plate 5, and the second trigger switch 3 is located inside the protective cover 33 to protect the second trigger switch 3. An adjustment hole is provided on the protective cover 33, and an adjustment member 34 is provided on the second sensor 31. The adjustment member 34 protrudes from the adjustment hole, and the second trigger switch 3 is rotated by the adjustment member 34. Specifically, the adjustment hole is an arc-shaped waist-shaped hole, and the adjustment member 34 moves within the adjustment hole when the second trigger switch is rotated.

[0044] In a preferred embodiment, the second trigger head 32 is a roller, and a trigger link 35 is rotatably connected to the second sensor 31. The second trigger head 32 is rotatably connected to the trigger link 35.

[0045] In a preferred embodiment, the base plate 5 includes a plate body 51 and a cover plate 52. The plate body 51 has multiple receiving slots, and the cover plate 52 is fixed on the plate body 51. The first trigger switch 2, the second trigger switch 3 and the timer 4 are all fixed in the receiving slots.

[0046] In a preferred embodiment, an assist rod 6 is also included. The assist rod 6 is detachably fixed to the base plate 5. The assist rod 6 is used to turn the hinge 7. In use, the assist rod 6 is removed from the base plate 5 and used to turn the hinge 7. Of course, the hinge 7 can also be turned by hand, but some hinges 7 are difficult to turn by hand, so the assist rod 6 is needed to amplify the torque.

[0047] In a preferred embodiment, the plate body 51 is marked with multiple angle auxiliary lines. The trigger head of the first trigger switch 2 is positioned at an angle of 0°±5° with the hinge. When the hinge 7 is a 180° buffer hinge 7, the position of the first trigger head 22 of the first trigger switch 2 and the fixed leaf of the hinge 7 are in the same plane. The trigger head of the second trigger switch 3 is positioned at an angle of 70°±5° with the fixed position of the hinge. When the hinge 7 is a 180° buffer hinge 7, the position of the second trigger head 32 of the second trigger switch 3 and the fixed hinge of the hinge 7 are at an angle of 70°±5°. In other embodiments, the angles between the first trigger switch 2 and the second trigger switch 3 and the hinge 7 can be other angles.

[0048] The procedure for using this fixture to inspect 180° buffer hinges:

[0049] 1. Power on: When the tooling and fixture are connected to the power supply, the timer will light up continuously and the displayed data will return to zero.

[0050] 2. Check the fixture: whether the first trigger switch 2 and the second trigger switch 3 are triggered normally, that is, whether the functions of timing, stopping, and resetting are correct, and whether the display value is displayed correctly.

[0051] 3. Retract switch: Turn off the first trigger switch and retract it.

[0052] 4. Clamping: Remove the hinge decorative cover, insert the first leaf (fixed end) of the hinge into the fixing plate 11, and move the clamping member 12 to fix the hinge.

[0053] 5. Assisting in turning the hinge: Use the assist lever 6 to turn the hinge to 90 degrees on the second leaf (moving end). This is the starting point for testing. (Refer to...) Figure 2 .

[0054] 6. Timer reset: Ensure the timer is in the reset state. If not, touch the switch to reset the timer.

[0055] 7. Release switch: Release the first trigger switch 2 by rotating the first handle 23 to remove the first trigger switch 2 from the protective cover.

[0056] 8. Inspection: With the help of a tension gauge, slowly push the second leaf of the hinge (opening force ≤ 40N). When it reaches 70 degrees ± 5 degrees, trigger the second trigger switch 3 and start the timer 4. Buffer to -3 degrees or -5 degrees (C), which triggers the first trigger switch 2 and the timer stops (buffer time is within 5 to 12 seconds).

[0057] 9. Retract switch: Retract the first trigger switch 2.

[0058] 10. Remove the hinge: Turn the clamping part 12 to remove the hinge, put the decorative cover back on, and complete the test of buffer time and angle.

[0059] The tooling fixture of this utility model for the buffer hinge 7 is equipped with a fixing component 1, a first trigger switch 2 and a second trigger switch 3. The timer 4 starts timing when the buffer hinge 7 triggers the second trigger switch 3 and stops timing when the first trigger switch 2 is triggered, so that the buffer time of the buffer hinge 7 can be calculated.

[0060] The positions of the first trigger switch 2 and the second trigger switch 3 can be adjusted, and the positions of the first trigger switch 2 and the second trigger switch 3 can be changed as needed, so that the tooling fixture can adapt to different models of hinges 7;

[0061] Angle markings are set on the base plate 5 to detect the rotation angle of the hinge 7.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
