[0031] Example 1

[0032] See Figures 1 to 6 The friction connector testing fixture includes a base 10, a fixed seat 20 on the base 10, and a friction connector 30 disposed on the fixed seat 20. The friction connector 30 includes a crank handle 40, a rotating shaft 31 and a gear 32. The rotating shaft 31 is disposed on the fixed seat 20, and the crank handle 40 is connected to the gear 32 through the rotating shaft 31.

[0033] A pull plate 60 is provided on the base 10, which is located below the friction connector 30. The pull plate 60 includes a locking block 11, which is located below the gear 32. The gear 32 drives the pull plate 60 to move through the locking block 11. A pressure sensor 80 is provided on one side of the pull plate 60.

[0034] In this embodiment, the locking block 11 is disposed on the base 10, and the pull plate 60 includes a pull plate hole 61, through which the locking block 11 is engaged with the pull plate 60.

[0035] In this embodiment, preferably, the fixing base 20 includes a protective cover 21, which can better protect the rotating shaft 31, thereby making the friction connector 30 more durable and long-lasting.

[0036] One side of the pull plate 60 includes a pressure sensor 80, and the pull plate 60 is connected to the pressure sensor 80; the locking block 11 is disposed below the gear 32; preferably, the gear 32 includes a tooth groove (not shown in the figure), and the locking block 11 is engaged in the tooth groove, and the gear 32 drives the locking block 11 to swing through the tooth groove;

[0037] When the crank handle 40 is turned, it drives the gear 32 to rotate through the rotating shaft 31. The gear 32 drives the pull plate 11 to move back and forth through the locking block 11, thereby allowing the pressure sensor 80 to test whether the friction force value of the friction connector 30 is normal.

[0038] See Figure 6 In this embodiment, preferably, the pressure sensor 80 includes a pressure sensor digital display 100, which is connected to the pressure sensor 80. The pressure sensor digital display 100 displays the friction pressure value in real time, making it convenient to monitor whether the friction pressure value is normal.

[0039] When the friction force value of the friction connector 30 is tested and found to be normal, it means that the friction connector 30 is normal. Only under these circumstances can the friction connector 30 be installed in the switch machine for use.

[0040] In the existing technology, the friction connector can only be installed in the switch machine before an external test bench can be connected to test whether the friction connector is working properly. The existing technology is not only inaccurate, but also time-consuming and labor-intensive, which greatly reduces work efficiency and increases labor costs.

[0041] This utility model is a new type of testing fixture for friction connectors, which not only tests the friction force value of friction connector 30 more accurately, but is also easier to use.

[0042] SeeFigure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 In this embodiment, preferably, one end of the rotating shaft 31 is connected to the crank handle 40, and the other end of the rotating shaft 31 includes a fixed head 50, which is connected to the fixed head 50 via a gear 32.

[0043] The fixing head 50 serves as a locking device for the friction connector 30, preventing the crank handle 40 from falling off when it is manually rotated, making it safer and more reliable to use.

[0044] In this embodiment, preferably, one side of the pull plate 60 includes a snap-fit ​​connector 62, through which the pull plate 60 is snapped onto the pressure sensor 80.

[0045] In this embodiment, the pull plate 60 is snapped onto the pressure sensor 80 via the snap-fit ​​connector 62, which not only makes the connection between the pressure sensor 80 and the pull plate 60 more secure, but also makes the test friction force value more accurate.

[0046] In this embodiment, and preferably, the snap-fit ​​connector 62 includes a crossbeam 623, with a first column 621 and a second column 622 at each end. The snap-fit ​​connector 62 is similar to a bridge shape. The pressure sensor 80 is snapped between the first column 621 and the second column 623, making the pressure sensor 80 more stable and reliable in use, and the test more accurate.

[0047] In this embodiment, preferably, a limiting block 90 is provided on the top of the pull plate 60, and the limiting block 90 abuts against the pull plate 60.

[0048] In this embodiment, the limiting block 90 abuts against the top of the pull plate 60, which restricts the pull plate 60 from moving up and down when it moves back and forth, so as to make the pressure sensor 80 test more accurately.

[0049] In this embodiment, preferably, the pressure sensor 80 includes a fixing groove 70, and the pressure sensor 80 is disposed in the fixing groove 70.

[0050] In this embodiment, and preferably, the fixing groove 70 includes a groove cover 71, a first groove wall 72 and a second groove wall 73, forming a fixing cavity between the first groove wall 72 and the second groove wall 73, and the pressure sensor 80 is snapped into the fixing cavity; at the same time, the snap-fit ​​connector 62 is snapped onto the pressure sensor 80. Using this utility model is more stable and safer, and the friction force test is more accurate and error-free.

[0051] The base 10 of this utility model is provided with a pull plate 60 and a crank handle 40. The crank handle 40 is sealed with a protective cover 21. The pull plate 60 has a protruding locking block 11 in the middle of its plane. Preferably, the locking block 11 is made of copper. The gear 32 of the friction connector 30 moves through the pull plate 60 to transmit the pressure value to the pressure sensor 80, thereby enabling the pressure sensor 80 to test the friction force value of the friction connector.

[0052] The fixing head 50 serves as a locking device for the friction connector 30, preventing the crank handle 50 from falling off when it is manually rotated. When the main body of the friction connector 30 is inserted into the rotating shaft 31 and locked, the crank handle 50 is rotated clockwise or counterclockwise at a uniform speed. At this time, the crank handle 50 drives the spindle of the friction connector 30 to rotate axially, while the gear 32 outside the friction connector 30 remains relatively stationary due to the blocking effect of the locking block 11, resulting in the spindle rotating freely clockwise or counterclockwise. At this time, the pull plate 60 is subjected to force and is squeezed to the left or right. The pull and pressure connected to the pressure sensor 80 and the pull plate 60 are transmitted to the pressure sensor digital display 100 to display a stable friction force value.

[0053] This utility model has a reasonable structure, is easy to operate, and provides accurate testing. It can perform real-time monitoring and is well-received by consumers.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
