Detailed Implementation

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0021] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] Example

[0023] To address the issue that existing tensile testing methods are inconvenient for conducting pull-nail tests, reference was made to... Figure 1 and Figure 2 As shown, this application discloses a tensile testing fixture, including a base plate 10, a tensile testing mechanism 20, and a product transport mechanism 30;

[0024] The tensile testing mechanism 20 includes a tensile gauge 21 located on one side above the base plate 10 and a snap-fit ​​component 22 connected to the pull head of the tensile gauge 21 for locking the pull rivet;

[0025] The product transport mechanism 30 includes a transport platform 31 slidably disposed above the middle of the base plate 10, a product positioning groove 311 opened on one side above the transport platform 31 and near the end of the snap-fit ​​22, a clamping member 32 disposed above the transport platform 31 for fixing the product, and a sliding adjustment member 33 connected to the transport platform 31 on the other side above the base plate 10 for driving the transport platform 31 to slide.

[0026] Based on the above structure, the working principle of the tensile testing fixture of this application is explained as follows: The operator first places the product in the product positioning slot 311 and snaps the rivets on the product into the snap fastener 22. Then the operator pulls the carrier platform 31 to move. At this time, the tensile gauge 21 will display the corresponding tensile value, thereby realizing the tensile test.

[0027] In one specific embodiment, the base plate 10 of this application is provided with two linear guide rails 312 in the upper center. The transport platform 31 is slidably connected above the two linear guide rails 312. When the operator pulls the transport platform 31, the transport platform 31 will move smoothly on the two linear guide rails 312.

[0028] Specifically, the snap-fit ​​connector 22 of this application is a U-shaped snap-fit ​​connector 22. The U-shaped snap-fit ​​connector 22 has a U-shaped groove 221 for inserting the rivet. When the product is placed in the product positioning groove 311, the head of the rivet will be stuck in the U-shaped groove 221. In this way, when the operator pulls the transport platform 31 to move, the tension gauge 21 can display the corresponding tension value.

[0029] As an example, the clamping member 32 in this application is a quick clamp. In addition, it should be noted that other clamping members 32 may be used in specific implementations of this technical field, as long as they can clamp the product in the product positioning groove 311. This application does not make any further requirements here.

[0030] In one specific embodiment, the sliding adjustment member 33 of this application includes a fixed seat 331 disposed on the base plate 10 and a retractable pull rod 332 inserted into the fixed seat 331 and fixed to the transport platform 31. In the specific implementation process, the operator can pull the pull rod 332 to make the transport platform 31 move on the two linear guide rails 312, thereby realizing the tension detection.

[0031] As an example, the force gauge 21 of this application is a digital display force gauge 21. During the tensile testing process, the operator can quickly read the value from the digital display force gauge 21, which is convenient to use and highly practical.

[0032] In the description of this specification, the references to terms such as "an embodiment," "example," "specific example," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

They should not be used to limit the scope of protection of this application. All equivalent changes or modifications made in accordance with the spirit and essence of this application should be included within the scope of protection of this application.
