Description

Technical Field

[0001] This utility model belongs to the field of testing, specifically relating to a high-temperature creep test rack for shear samples. Background Technology

[0002] Adhesives are a class of natural or synthetic, organic or inorganic substances that bond two or more parts or materials together through interfacial adhesion and cohesion. They are also called adhesives or simply glue. In short, adhesives are substances that bind materials together through bonding. "Adhesive" is a common standard term and also includes other types of glues, putties, pastes, and adhesives.

[0003] When testing the performance of adhesives, especially their creep properties, two objects are typically glued together with the adhesive, suspended vertically with a weight attached, and the separation is observed. However, most existing testing tools can only test one set of shear samples simultaneously, resulting in lower test results and less intuitive experimental comparisons. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a high-temperature creep test rack for shear samples.

[0005] To achieve the above and other related objectives, this utility model provides a high-temperature creep test frame for shear samples. The test frame includes a support, a first crossbar fixed on the support, a second crossbar fixed on the support and arranged parallel to the first crossbar, at least one support rod detachably mounted between the first and second crossbars, a first test plate hung on the support rod, a second test plate bonded to the first test plate with test adhesive, and weights hung at the bottom of the second test plate.

[0006] The first crossbar is provided with a plurality of first notches for the first end of the support rod to be inserted and connected, and the second crossbar is provided with a plurality of second notches for the second end of the support rod to be inserted and connected.

[0007] Optionally, the top of the first test plate is provided with a first through hole through which the support rod can pass, and the bottom of the second test plate is provided with a second through hole through which the weight hook can pass.

[0008] Optionally, the support rod is a square rod, and the first through hole is a square hole.

[0009] Optionally, a receiving plate is fixed on the bracket directly below the first test plate and the second test plate.

[0010] Optionally, the receiving plate is fixedly connected to the bracket via a connecting rod, or the receiving plate is fixedly connected to the first crossbar and the second crossbar via a connecting rod.

[0011] As described above, the high-temperature creep test frame for shear samples of this utility model has the following beneficial effects: Using the high-temperature creep test frame for shear samples of this utility model, the bottom end of the first test plate and the top end of the second test plate are glued together. A weight is hung on the bottom end of the second test plate, and then the first test plate is hung on a support rod. Finally, the two ends of the support rod are placed in the first notch and the second notch, respectively, to suspend the first test plate, the second test plate, and the weight. The shear strength of the adhesive is then tested by relying on the gravity of the weight, and the test data is recorded. In this application, multiple sets of shear strength test samples can be hung on the same support rod for testing simultaneously, or multiple sets of shear strength test samples can be hung on different support rods, and then the different support rods are hung in different first notch and second notch slots for testing, thereby achieving simultaneous testing of multiple sets of shear strength test samples, facilitating observation and comparison.

It will be understood that these spatial relation terms are intended to include directions other than those depicted in the drawings for devices in use or operation. Furthermore, when a layer is referred to as being “between” two layers, it may be the only layer between the two layers, or there may be one or more layers in between.

[0015] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show components related to this utility model and are not drawn according to the actual number, shape, and size of the components in the actual implementation.

[0016] like Figure 1 As shown, this embodiment provides a high-temperature creep test frame for shear samples. The test frame 10 includes a support 11, a first crossbar 12 fixed on the support 11, a second crossbar 13 fixed on the support 11 and arranged parallel to the first crossbar 12, at least one support rod 14 detachably mounted between the first crossbar 12 and the second crossbar 13, a first test plate 15 hung on the support rod 14, a second test plate 16 bonded to the first test plate 15 with test adhesive, and a weight 17 hung at the bottom of the second test plate 16.

[0017] The first crossbar 12 is provided with a plurality of first notches 18 for the first end of the support rod 14 to be inserted and connected, and the second crossbar 13 is provided with a plurality of second notches 19 for the second end of the support rod 14 to be inserted and connected.

[0018] According to ASTM D1002, the standard for testing the shear strength of adhesives for bonding metals, both the first test plate 15 and the second test plate 16 are metal plates.

[0019] Using the high-temperature creep test frame 10 for shear samples of this invention, the bottom of the first test plate 15 and the top of the second test plate 16 are glued together. A weight 17 is hung on the bottom of the second test plate 16. The first test plate 15 is then hung on a support rod 14. Finally, both ends of the support rod 14 are placed in the first notch 18 and the second notch 19, respectively, to suspend the first test plate 15, the second test plate 16, and the weight 17. The shear strength of the adhesive is then tested by the gravity of the weight 17, and the test data is recorded. In this application, multiple sets of shear strength test samples can be hung on the same support rod 14 for testing simultaneously, or multiple sets of shear strength test samples can be hung on different support rods 14, and then the different support rods 14 are hung in different first notch 18 and second notch 19 for testing, thus achieving simultaneous testing of multiple sets of shear strength test samples and facilitating observation and comparison.

[0020] Specifically, the top of the first test plate 15 is provided with a first through hole 20 through which the support rod 14 can pass, and the bottom of the second test plate 16 is provided with a second through hole 21 through which the hook of the weight 17 can pass.

[0021] Preferably, to prevent the support rod 14 from rotating and wobbling, and at the same time to prevent the first test plate 15 from rotating and wobbling, the support rod 14 is a square rod, and the first through hole 20 is a square hole.

[0022] Furthermore, a receiving plate 22 is fixedly mounted on the bracket 11 directly below the first test plate 15 and the second test plate 16.

[0023] By setting up the receiving plate 22, when the second test plate 16 and the weight 17 are separated from the first test plate 15, the receiving plate 22 can catch the second test plate 16 and the weight 17, preventing them from falling and damaging other experimental equipment.

[0024] Specifically, the receiving plate 22 is fixedly connected to the bracket 11 via the connecting rod 23, or the receiving plate 22 is fixedly connected to the first crossbar 12 and the second crossbar 13 via the connecting rod 23.

[0025] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
