Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are merely illustrative of this utility model. Key terms used in these descriptions, including "smooth groove," "straight groove," "smooth block," and "straight slider," are simply customary names used for ease of description and to simplify the description; therefore, they should not be construed as limitations on this utility model.

[0015] This utility model relates to a universal testing fixture for the tensile strength of nylon rear support frames in electric vehicles, such as... Figure 2-5 As shown, its general-purpose testing fixture T includes a flat plate T1, a straight plate T2, a smooth block T4, a straight slider T6, a first connecting rod T8, and a second connecting rod T9. The flat plate T1 and the straight plate T2 are perpendicular to each other and fixedly connected together. The flat plate T1 is provided with a connecting hole corresponding to the connecting hole of the tensile testing machine. The straight plate T2 is provided with a stepped slide groove T10, and a flat groove T3 is also opened in the stepped slide groove T10. The straight plate T2 is also provided with a straight groove T5 and a connecting groove T7. The flat groove T3 is arranged horizontally, and the straight groove T5 is arranged vertically. The connecting groove T7 corresponds to the connecting hole of the tensile testing machine. The smooth block T4 is provided with a large adjustment range. It is connected to the straight plate T2 via the connecting hole of the smooth block T4, the stepped slide groove T10 and the flat groove T3 by screws. The straight slider T6 is provided with a connecting hole. It is connected to the straight plate T2 via the connecting hole of the straight slider T6 and the straight groove T5 by screws. The connecting rod T8 and the connecting rod T9 are threaded. The connecting rod T8 is screwed into the connecting hole of the flat plate T1 and the connecting rod T9 is screwed into the connecting groove T7 for screw connection with the tensile testing machine.

[0016] In use, as described above, the universal testing fixture T is fixedly connected to the tensile testing machine via connecting rod T8 and connecting rod T9. In this embodiment, the rear support P is first fixed to the universal testing fixture T, as follows... Figure 1 As shown, the rear support frame P has a front mounting hole P1 and a rear mounting hole P2. The rear support frame P and the universal testing fixture T are fixedly connected by screws, sequentially passing through the front mounting hole P1, the connecting hole of the smooth block T4, the stepped slide groove T10, and the flat groove T3. The rear support frame P and the universal testing fixture T are also fixedly connected by screws, sequentially passing through the rear mounting hole P2, the connecting hole of the straight slider T6, and the straight groove T5. Because the flat groove T3, straight groove T5, smooth block T4, and straight slider T6 of the universal testing fixture T allow for adjustment of the connection positions of the front mounting hole P1 and the rear mounting hole P2 at different distances on the rear support frame P, this invention possesses versatility. During testing, a tensile force L is applied, and the tensile force of the rear support frame can be tested using a tensile testing machine.

[0017] The above description is only a general embodiment of this utility model. For those skilled in the art, there are various other embodiments with modifications and variations, which will not be elaborated here. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model are included within the protection scope claimed by this utility model.
