Detailed Implementation

[0024] As shown in Figure 1, this embodiment includes a box body 1, a rotating box assembly 2, a load 3, a sample 4, a stop 5, and a sliding assembly 6.

[0025] As shown in Figures 3-6, the box 1 in this embodiment adopts a cubic structure. In other embodiments, the box 1 may also adopt a cylindrical or prism structure, depending on the shape of the sample 4. The box 1 is provided with a heating cavity 1a, and the top of the heating cavity 1a has an opening. It should be noted that the descriptions of top, bottom, upper, lower, etc. in this application are all based on the corresponding drawings in the specification.

[0026] The heating chamber 1a is equipped with a heating wire 1b and a fan 1c. The fan 1c blows the heat from the heating wire 1b toward the opening of the heating chamber. Specifically, there are three sets of heating wires 1b and fans 1c, which are linearly and evenly distributed in the middle of the heating chamber 1a. Of course, in other embodiments, the heating wires 1b and fans 1c can also be set to two or four sets, or other numbers, and the specific distribution of the heating wires 1b and fans 1c can also be determined according to the actual situation.

[0027] In this embodiment, the heating wire 1b is made of nickel-chromium metal wire, controlled by an SSR, and equipped with a fault-protected temperature switch. The heating wire 1b is spiral-shaped, with one end of the spiral facing the opening of the heating cavity 1a and the other end facing the bottom of the heating cavity 1a. The fan 1c in this embodiment includes a fan blade 1c1 and a drive 1c2. The fan blade 1c1 is located inside the other end of the spiral of the heating wire 1b, and the drive 1c2 is located outside the bottom of the heating cavity 1a. The drive 1c2 is connected to the fan blade 1c1 via a stainless steel shaft passing through the bottom of the heating cavity 1a and drives the fan blade 1c1 to rotate. In this embodiment, the fan 1c blows the heat generated by the heating wire 1b towards the opening of the heating cavity 1a. Therefore, regardless of whether the opening of the heating cavity faces upwards or to the side, the heat flow is always towards the heating surface of the sample 4.

[0028] In this embodiment, a partition 1d is provided between the three sets of heating wires 1b and the fan 1c, and the partition 1d is higher than the height of the heating wires 1b. It also includes a support plate 1e, which covers the partition 1d. The support plate 1e has a through hole at the position corresponding to one end of the spiral of the heating wire 1b. The through hole is used for gas flow. In this embodiment, a wire mesh 1e1 is provided at the position of the through hole.

[0029] The width of the partition 1d should be slightly smaller than the width of the heating chamber 1a. This allows heat to escape from the wire mesh 1e1 and then return through the gap between the partition 1d and the side wall of the heating chamber 1a. Therefore, the gap and the space isolated by the partition 1d must be connected, meaning the length of the gap is perpendicular to the length of the partition 1d. This creates an internal circulation, ensuring uniform temperature in the heating chamber 1a. In this embodiment, convection is used to heat the heating surface of the sample 4, ensuring uniform heating regardless of the orientation of the heating chamber opening. Furthermore, since the sample 4 may be damaged and fall during the heating load process, the support plate 1e prevents the damaged sample 4 from damaging the heating wire 1b.

[0030] Preferably, the housing 1 has several cavities 1f surrounding the heating chamber 1a, and the cavities 1f are filled with heat insulation cotton. This structure ensures that the heat from the heating chamber 1a is not easily lost, and also ensures that the person will not be burned by the heat from the heating chamber 1a when the housing 1 is rotated.

[0031] In this embodiment, a thermocouple sensor 7 is also installed in the heating chamber 1a. The thermocouple sensor 7 transmits the heating data inside the heating chamber, providing a basis for the acquisition of test data.

[0032] The opening of the heating chamber 1a is lower than the opening of the housing 1. The height difference between the opening of the heating chamber 1a and the housing 1 forms a groove 1g. In this embodiment, the depth of the groove 1g is equal to the thickness of the sample 4. The sample 4 is placed on the groove 1g and completely seals the opening of the heating chamber 1a. In this embodiment, the sample 4 has reinforcing ribs on the heating surface. Therefore, notches 1a1 are provided on the two sides of the opening of the heating chamber 1a to accommodate the reinforcing ribs. In other embodiments, the reinforcing ribs may not be provided.

[0033] In this embodiment, the stop 5 is strip-shaped. One end of the stop 5 is fixed to the opening of the housing 1 with screws, and the other end of the stop 5 presses against the sample 4 to prevent the sample 4 from falling out of the groove 1g. In other embodiments, the stop 5 can be made into a circle or a square, and one end of the stop 5 can be set as a rotating structure, so that the other end of the stop 5 can press against or detach from the sample 4 by rotating around a pivot.

[0034] The sliding assembly 6 includes a slide rail 6a and a slider 6b. The slide rail 6a is located next to one side of the sample 4. When the heating chamber opening faces to the side, the slide rail 6a is pressed against the side of the sample 4, as shown in Figure 2. The slider 6b can slide back and forth on the slide rail 6a. The load 3 is pressed on the slider 6b. In this structure, the load point on the side of the sample 4 can be changed by sliding the slider 6b.

[0035] Preferably, in this embodiment, a notch is provided on one side of the groove 1g, and the length of the notch is exactly equal to the length of that side of the groove 1g. In other embodiments, the length of the notch can be less than the length of that side of the groove 1g. The slide rail 6a is disposed within the notch. Slide grooves are provided at both ends of the notch, with the length direction of the slide grooves pointing towards the opposite side of the side where the notch is located. Slide protrusions 6a1 corresponding to the slide grooves are provided at both ends of the slide rail 6a, and the slide protrusions 6a1 can slide back and forth within the slide grooves along the length direction of the slide grooves. A baffle 8 is also included, which is fixed to the housing 1 by screws, and the baffle 8 seals the slide protrusions 6a1 within the slide grooves. Due to the action of the slide grooves and the slide protrusions 6a1, when the heating chamber opening faces sideways, even if the sample 4 deforms, the load 3 can sink following the deformation of the sample 4, ensuring that the attachment always acts on the sample 4.

[0036] When the heating chamber opening faces upward, the load 3 is placed directly on top of the sample 4. It should be noted that the sample 4 and the heating chamber 1a in this embodiment do not form a completely sealed state. Even if the pressure in the heating chamber 1a increases due to heating, gas will still escape from the gap between the sample 4 and the heating chamber 1a. Of course, if necessary, vent holes can be provided on the side wall of the heating chamber 1a.

[0037] In this embodiment, a barrel-shaped support platform 6c is also provided on the slider 6b, and the load 3 is placed inside the support platform 6c to prevent it from slipping.

[0038] This embodiment also includes a load-bearing support 9, which is vertically fixed beside the receiving box 2a without interfering with the rotation of the receiving box 2a around the hinge axis. The top of the load-bearing support 9 has a support arm 9a perpendicular to the load-bearing support 9, and a load 3 is suspended from the support arm 9a. Specifically, the load 3 can be a weight structure, making it convenient to add or remove weights. Since the heating chamber opening faces upwards and to the side, the placement position of the load 3 differs. Therefore, two ropes can be installed on the support arm 9a corresponding to the placement position of the load 3 to suspend the weights.

[0039] For existing high-temperature test furnaces, when the model is damaged during testing, the applied weight will fall directly into the furnace, damaging the internal structure such as thermocouples and side walls. Therefore, this embodiment sets up a load-bearing support 9. When the sample 4 is damaged, the load-bearing support 9 will pull the load 3 to prevent the load 3 from falling into the furnace.

[0040] The rotating box assembly 2 in this embodiment includes a receiving box 2a and a seat 2b. The box body 1 is fitted inside the receiving box 2a and exposes the opening of the heating chamber 1a. Of course, the opening edge of the receiving box 2a should not obstruct the movement of the load 3 with the slider 6b. The bottom end of the seat 2b is fixed, and the top end of the seat 2b is hinged to the receiving box 2a. The receiving box 2a can rotate at least 90° around the hinge axis. In this embodiment, the sample 4 can not only withstand out-of-plane loads for testing, but also achieve in-plane load testing by rotating the box body 1 by 90°.

[0041] Preferably, this embodiment also includes a base 10, with casters 10a at the bottom, and the base 2b and the bottom of the load-bearing bracket 9 fixed to the base 10. The base 10 allows the test chamber to be moved around freely.

[0042] Preferably, the base 10 is further provided with a threaded through hole, and also with several support members 11. Each support member 11 includes a support seat and a screw rod. The top end of the support seat abuts against and supports the receiving box 2a, and the bottom end of the support seat is fixed to the end of the screw rod. The screw rod passes through the threaded through hole, and the height of the support seat can be adjusted by rotating the screw rod. With this structure, regardless of the shape of the box 1 or how it rotates, the support member 11 can support the box 1.

[0043] As shown in Figure 7, in other embodiments, a bracket 1h and a loading frame 1i are also included; the bracket 1h is located at the opening of the heating chamber; the loading frame is located on the bracket 1h, and the loading frame 1i is provided with a sample mounting port. The size of the sample mounting port can be freely adjusted. Specifically, the loading frame 1i includes two vertical rods and two horizontal rods. The two vertical rods are arranged parallel to each other and can be moved horizontally on the bracket 1h, and the two horizontal rods are arranged parallel to each other and can be moved vertically between the two horizontal rods. In this way, the size of the sample mounting port can be adjusted by adjusting the distance between the two vertical rods or the distance between the two horizontal rods, so that samples 4 of different sizes can be tested.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
