[0002] Server chassis torsional strength is one of the strength tests for server chassis, used to measure the rigidity and strength of the server chassis. This test mainly simulates the stress that a server may face during transportation or use to test the chassis's resistance to torsion.

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0046] like Figure 1As shown, this invention provides a server chassis 500 torsion testing device, including a fixing base 100, a first stop component 200, a second stop component 300, and a mounting base 400. It should be noted that the torsion test of the server chassis 500 belongs to a type of hardware mechanical load test, mainly used to detect whether the stability and operational performance of the internal equipment and connections of the server chassis will be affected when subjected to different degrees of torsion or deformation pressure. The torsion of the server chassis 500 may come from various reasons, such as the movement of server equipment, transportation, or even earthquakes. The purpose of the test is to ensure that even in extreme environments, the server chassis 500 can maintain normal operation and will not cause server failure due to torsion or deformation of the server chassis 500.

[0047] Specifically, such as Figure 3 and Figure 4 As shown, the mounting base 100 is used to support the server chassis 500 under test. The mounting base 100 can support and stably support the server chassis 500 under test, ensuring the stability of the server chassis 500 during the test. The first abutment component 200 is provided on one side of the mounting base 100, and is used to abut the server chassis 500 under test from one side. The first abutment component 200 can fix the position of the server chassis 500, preventing the server chassis 500 from moving or sliding during the test, ensuring the accuracy of the test and the safety of the server chassis 500, and ensuring the smooth progress of the test.

[0048] The second abutment component 300 can be located on the other side of the mounting base 100 to abut the server chassis 500 under test from the other side. In this way, through the cooperation of the first abutment component 200 and the second abutment component 300, the chassis of the server under test is abutted respectively, so that the un-abutted part of the server chassis 500 under test is naturally suspended, thereby creating a displacement difference between the un-abutted part and the part abutted by the abutment components. This displacement difference is the torsion parameter of the server chassis 500 under test.

[0049] Meanwhile, by providing multi-sided stop mechanisms to the server chassis 500, the server chassis 500 is supported and secured in multiple directions, thereby further improving the stability of the server chassis 500 during testing. This prevents the server chassis 500 from moving or sliding during testing, which could interfere with the test data and ensure the accuracy of the test. Furthermore, by combining the first stop component 200 with the second stop component, the risks caused by equipment movement are reduced more effectively, improving the lifespan and operational efficiency of the testing equipment.

[0050] Mounting base 400 is connected to fixed base 100. Mounting base 400 is used to support detection element 600, thereby providing a stable and reliable fixed position and platform for detection element 600. Detection element 600 is used to detect the torsion parameters of the server chassis 500 under test and presents the final measured torsion parameters of the server chassis 500, which facilitates subsequent data analysis and evaluation of the performance of the server chassis 500.

[0051] By placing the detection element 600 on the mounting base 400, the detection element 600 can be stably installed or fixed in the predetermined position, thereby ensuring more accurate and stable detection of the torsion parameters of the server chassis 500 under test. Furthermore, the mounting base 400 protects the detection element 600 from damage by vibration or impact, ensuring its normal operation. At the same time, the mounting base 400 also facilitates the installation and replacement of the detection element 600.

[0052] According to the server chassis 500 torsion testing device provided by the present invention, by placing the server chassis 500 under test on the fixed base 100, the first abutment component 200 abuts the server chassis 500 under test from one side, and the second abutment component 300 abuts the server chassis 500 under test from the other side, and the un-abutted portion of the server chassis 500 under test is left unaffected, thereby creating a displacement difference between the un-abutted portion and the portion abutted by the abutment components. This displacement difference can be transmitted to the detection element 600, allowing the detection element 600 to display the final measured torsion parameters, facilitating subsequent data analysis and evaluation of the server chassis 500's performance. The device is easy to operate, reduces measurement errors, and improves measurement accuracy.

[0053] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the first stop component 200 can be a stop rod 201, which passes through the fixed base 100 to stop against the server chassis 500 under test. The length of the stop rod 201 passing through the fixed base 100 is adjustable. By adjusting the length of the stop rod 201 passing through the fixed base 100, the distance between the server chassis 500 and the fixed base 100 can be precisely controlled, thereby providing different torsional test intensities to the server chassis 500, providing multiple sets of test data, and improving test accuracy. Simultaneously, the length of the stop rod 201 passing through the fixed base 100 can be adjusted according to different server chassis 500 sizes, allowing the server chassis 500 testing device to adapt to various specifications of server chassis 500, improving the versatility and flexibility of the server chassis 500 testing device. The adjustable design of the stop rod 201 also facilitates the installation and operation of the equipment, improving work efficiency.

[0054] like Figure 1 , Figure 4 and Figure 6 As shown, in some embodiments of the present invention, the stop rod 201 includes a main rod 202 and a cap 203. The main rod 202 passes through the fixed base 100, and one end of the main rod 202 abuts against the server chassis 500 under test, so that the main rod 202 can accurately and reliably control the distance between the server chassis 500 and the test equipment, thereby ensuring the accuracy of the test results. The outer periphery of the main rod 202 is provided with external threads to increase the friction between the main rod 202 and the fixed base 100, making the connection between the main rod 202 and the fixed base 100 more stable. The cap 203 is provided at the other end of the main rod 202, and the cap 203 is fixedly connected to the main rod 202. This ensures that the stop rod 201 can still maintain its stability when making large adjustments, avoiding inaccurate test results caused by the wobbling of the stop rod 201 due to the need to adjust the length. Furthermore, the length of the stop rod 201 can be easily adjusted using the external thread, allowing for precise adaptation to the dimensions of the server chassis 500 under test, thus expanding the range of testable devices and improving the applicability of the testing equipment.

[0055] Specifically, such as Figure 6 As shown, in some embodiments of the present invention, the cap body 203 can be a hand-cranked cross handle 204, which facilitates manual operation. By manually turning the cross handle 204, the main rod 202 is screwed into the fixed base 100, allowing for precise adjustment of the position of the stop rod 201 and ensuring work accuracy. Furthermore, the shape of the hand-cranked cross handle 204 is easy to grip, and the gripping method and direction are simple and intuitive, making it easy for the operator to master the control method. This allows users to operate the equipment more stably, reducing safety risks caused by improper operation and improving work efficiency.

[0056] The contact point between the main rod 202 and the server chassis 500 can be a support round head 205. Setting the contact point between the main rod 202 and the server chassis 500 as a support round head 205 allows for better and more even pressure distribution on the server chassis 500, avoiding pressure concentration and thus preventing damage to the server chassis 500 due to excessive pressure. Furthermore, the shape of the support round head 205 reduces friction during contact with the server chassis 500, making torsion testing smoother and minimizing damage to the server chassis 500. Finally, the support round head 205 can also adapt well to server chassis 500s of different shapes, improving the applicability and versatility of the testing device.

[0057] like Figure 2As shown, in some embodiments of the present invention, the first abutment component 200 can be a plurality of spaced-apart components. Providing multiple spaced-apart first abutment components 200 allows the first abutment components 200 to support the server chassis 500 under test at multiple points during torsion testing, thereby ensuring the accuracy of the test and the stability of the server chassis 500, and preventing the test results from being affected by shaking or displacement of the server chassis 500 during torsion. Simultaneously, multi-point support of the server chassis 500 can better simulate various situations that the server chassis 500 may encounter in actual use, improving the comprehensiveness and reliability of the test.

[0058] As shown in Figure 3, in some embodiments of the present invention, in order to adapt to server chassis 500 of different sizes and models, the second stop component 300 is slidably disposed on the fixed base 100, so that the second stop component 300 can slide and adjust on the fixed base 100. This allows the second stop component 300 to be flexibly positioned and fixed to the server chassis 500 under test, and can achieve fastening and fixing of chassis of different sizes. This improves the flexibility and versatility of the server chassis 500 torsion testing device, enabling it to handle more specifications of server chassis 500. At the same time, the slidable adjustment of the second stop component 300 also facilitates the setup and debugging of the server chassis 500 torsion testing device, enabling testers to conduct fast and efficient testing.

[0059] like Figure 1 As shown, in some embodiments of the present invention, the second stop assembly 300 includes a sliding strip 301 and a stop rod 201. The sliding strip 301 is slidably connected to the fixed base 100, allowing the sliding strip 301 to slide on the fixed base 100, thereby achieving position adjustment of the second stop assembly 300. The stop rod 201 passes through the sliding strip 301 to stop against the server chassis 500 under test. The length of the stop rod 201 passing through the sliding strip 301 is adjustable, further enhancing the flexibility of adjusting the second stop assembly 300. Not only can the position of the stop assembly be adjusted, but its height can also be adjusted. This design has good adaptability to server chassis 500s of different heights and lengths. By changing the position of the sliding strip 301 and the length of the stop rod 201, the contact position and pressure level between the stop rod 201 and the server chassis 500 can be easily adjusted, facilitating user operation according to needs during testing and improving testing efficiency and convenience.

[0060] like Figure 1As shown, in some embodiments of the present invention, there are multiple stop bars 201, which are spaced apart along the length of the sliding bar 301. The multiple spaced stop bars 201 allow for a more uniform pressure distribution on the server chassis 500, thus better stabilizing the server chassis 500 during testing and preventing instability such as tilting or sliding due to uneven pressure. Simultaneously, multiple stop bars 201 provide more contact points, increasing the friction between the stop bars 201 and the chassis, and improving the stability of the stop device. Furthermore, the multiple stop bars 201 allow users to easily adjust their number and position according to actual needs, further increasing its flexibility and convenience.

[0061] like Figure 1 As shown, in some embodiments of the present invention, the mounting base 100 is provided with a first through hole 101 and a second through hole 102. The first stop component 200 passes through the first through hole 101, and the second stop component 300 passes through the second through hole 102. In this way, the through holes can restrict the movement of the stop components in the circumferential direction, improving the stability of the stop components and preventing them from shaking when abutting the server chassis 500 under test, thereby improving the accuracy of the test and reducing errors. Furthermore, by providing the first through hole 101 and the second through hole 102, the first stop component 200 and the second stop component 300 can be positioned at different locations on the mounting base 100, allowing the pressure of the stop components to be distributed more evenly on the chassis, preventing instability such as tilting or sliding of the chassis during testing.

[0062] By providing multiple through holes on the mounting base 100, the number of stop components can be increased or decreased as needed to accommodate chassis of different sizes or models, thus expanding the applicability of the server chassis 500 torsion testing device. Since the stop components pass through the through holes, their installation and removal are very convenient and do not affect other parts during installation or removal, improving the practicality and maintenance efficiency of the server chassis 500 torsion testing device.

[0063] In some embodiments of the present invention, the first through hole 101 can be an elongated hole. Using an elongated hole allows for convenient fine-tuning of the position of the first stop component 200, enabling it to adapt to server chassis 500s of different sizes and shapes, increasing the versatility and flexibility of the server chassis 500 torsion testing device. Simultaneously, by moving the first stop component 200, its position on the server chassis 500 under test can be more precisely controlled and adjusted to meet different testing requirements, such as the need to perform torsion tests on different parts of the server chassis 500. Of course, the elongated hole is not limited to the first through hole; in other embodiments of the present invention, the second through hole 102 can also be an elongated hole. Alternatively, in other embodiments of the present invention, both the first through hole 101 and the second through hole 102 can be elongated holes.

[0064] like Figure 1 As shown, in some embodiments of the present invention, the mounting base 400 is slidably connected to the fixed base 100. This allows the mounting base 400 to be appropriately adjusted and positioned according to the actual size and shape of the server chassis 500 under test, ensuring that the detection element 600 on the mounting base 400 can accurately position and detect the server chassis 500 under test, thus improving testing accuracy. This design increases the applicability and flexibility of the server chassis 500 testing device, making it suitable for server chassis 500 of different sizes and shapes, thereby improving testing accuracy and efficiency.

[0065] like Figure 1 As shown, in some embodiments of the present invention, the fixed base 100 is provided with a slide rail 103, and the mounting base 400 is provided with a slider adapted to the slide rail 103. The cooperation between the slider and the slide rail 103 allows the mounting base 400 to slide freely on the fixed base 100, enabling the server chassis 500 testing device to be flexibly adjusted according to different server chassis 500 shapes and sizes, thus improving the adaptability of the server chassis 500 torsion testing device. Furthermore, the structure of the slide rail 103 and the slider can precisely control the movement position of the mounting base 400, thereby ensuring that the testing device performs more accurate torsion testing on the server chassis 500, improving the accuracy of the test results. The cooperation between the slide rail 103 and the slider also makes the mounting base 400 more stable, avoiding deviations caused by manual position adjustments and reducing errors during the testing process. The structural design of the slide rail 103 and the slider makes adjusting the position of the mounting base 400 simple and direct, reducing operation time and difficulty, and improving testing efficiency.

[0066] like Figure 1As shown, in some embodiments of the present invention, the slide rails 103 are two spaced-apart rails, and the mounting base 400 is located between the two slide rails 103. Each mounting base 400 has a slider at a position corresponding to one of the slide rails 103. This allows the two spaced-apart slide rails 103 to support the mounting base 400, making its movement more precise and its position control more refined, thereby improving test accuracy. Furthermore, this design ensures the stability of the torsion test process, preventing the mounting base 400 from shaking or shifting during testing, ensuring that the detection element 600 can accurately perform the torsion test on the server chassis 500 under test, thus enhancing test reliability. Moreover, the two slide rails 103 facilitate easy adjustment of the mounting base 400's position, making the adjustment process simple and quick, improving equipment operation and work efficiency. The two slide rails 103 allow the mounting base 400 to adapt to more types and sizes of server chassis 500, increasing the practicality and applicability of the testing device.

[0067] In some embodiments of the present invention, the surface of the slide rail 103 is provided with a scale (not shown in the figure). When testing server chassis 500 of different sizes, the distance the mounting base 400 slides on the slide rail 103 can be precisely controlled according to the scale, thereby improving the accuracy of the test, reducing errors, and ensuring the stability of the quality and performance of the server chassis 500.

[0068] like Figure 1 As shown, in some embodiments of the present invention, the mounting base 400 may be elongated, and a sliding groove 401 is provided on the mounting base 400, within which the detection element 600 is disposed. The extending direction of the sliding groove 401 is the same as the length direction of the mounting base 400, so that the detection element 600 can slide along the length direction of the mounting base 400, allowing the detection element 600 to test the displacement values ​​at different positions on the server chassis 500 under test. This allows the position of the detection element 600 to be flexibly adjusted as needed to accommodate server chassis 500 of different sizes under test. Simultaneously, precise control of the detection element 600 can be achieved, making the testing process more flexible and accurate.

[0069] In some embodiments of the present invention, such as Figure 1As shown, the detection element 600 includes a displacement difference calculation screen 602 and displacement sensors 601. The displacement sensors 601 are communicatively connected to the displacement difference calculation screen 602, and there can be two or more displacement sensors 601. It should be noted that in this embodiment, two displacement sensors 601 are used. Specifically, the displacement sensors 601 are located on both sides of the calculation screen. During the test, one displacement sensor 601 records the displacement value of the stopped part of the server chassis under test, and then transmits the displacement value to the displacement difference calculation screen 602; the other displacement sensor 601 records the displacement value of the suspended part of the server chassis under test, and then transmits the displacement value to the displacement difference calculation screen 602; the displacement difference calculation screen 602 calculates and outputs the displacement difference value, allowing the tester to visually see the degree of distortion data of the server chassis 500.

[0070] like Figure 5 As shown, in some embodiments of the present invention, the displacement sensor 601 includes a stud 603, a nut 604, and a sensor body 605. Specifically, the stud 603 is connected to the sensor body 605, and the nut 604 passes through the stud 603. The nut 604 is slightly larger than the width of the sliding groove 401, so that when the displacement sensor 601 is placed on the mounting base 400, the nut 604 can be engaged in the sliding groove 401, thereby fixing the sensor body 605 below the mounting base 400 and improving the stability of the displacement sensor 601. Compared to placing the sensor body 605 above the mounting base 400, fixing the sensor body 605 below the mounting base 400 allows the sensor body 605 to be closer to the server chassis 500 under test, thereby improving the accuracy of the displacement sensor 601.

[0071] like Figure 1 As shown, in some embodiments of the present invention, the fixing base 100 includes a base plate 104 and a side plate 105. A first through hole 101 is provided in the base plate 104, and a first stop assembly 200 passes through the base plate 104. The side plate 105 is provided on one side of the base plate 104, and one end of the side plate 105 is connected to the base plate 104. The side plate 105 and the base plate 104 can be integrally formed, for example, the side plate 105 and the base plate 104 can be integrally formed by welding. In this way, the integrally formed side plate 105 and the base plate 104 can avoid additional connecting parts, thereby saving materials and manufacturing costs. Furthermore, the integrally formed side plate 105 and the base plate 104 do not require additional connecting work, simplifying the production and installation process and reducing safety hazards caused by disassembly. Moreover, the integrally formed side plate 105 and the base plate 104 have a more stable connection, are less prone to loosening or damage, and improve the stability and service life of the equipment.

[0072] Of course, the connection method between the side plate 105 and the base plate 104 is not limited to this. In some other embodiments of this application, in order to facilitate equipment maintenance, the side plate 105 can also be connected to the base plate 104 in a detachable form. Specifically, depending on the usage environment and needs, either the side plate 105 integrally formed with the base plate 104 or the detachable side plate 105 can be selected.

[0073] The side panel 105 and the bottom plate 104 together define the test cavity 106. The server chassis 500 under test is disposed within the test cavity 106. The first abutment component 200 abuts against the bottom surface of the server chassis 500 under test. It should be noted that the bottom surface of the server chassis 500 under test is the side that contacts the bottom plate 104. The connection between the bottom plate 104 and the side panel 105 forms a stable bottom support structure, providing solid support for the server chassis 500 under test, ensuring that the chassis will not shake or tilt during the test, and ensuring the accuracy and reliability of the test results.

[0074] The mounting base 400, the second stop assembly 300, and the other end of the side plate 105 are all connected. The second stop assembly 300 abuts against the top surface of the server chassis 500 under test. It should be noted that the top surface of the server chassis 500 under test is the side opposite to the bottom surface. The side plate 105 provides a stable support structure for the mounting base 400 and the second stop assembly 300, so that the mounting base 400 can be stably installed on the fixed base 100, improving the stability of the mounting base 400 and the second stop assembly 300, and preventing the detection element 600 and the second stop assembly 300 from shaking during testing.

[0075] like Figure 1 As shown, in some embodiments of the present invention, the length of the stop rod 201 of the second stop component 300 is greater than the length of the stop rod 201 of the first stop component 200, so that the second stop component 300 can smoothly stop the top surface of the server chassis 500 under test, prevent the server chassis 500 under test from shaking, reduce test errors, and ensure the reliability of the test.

[0076] like Figure 2As shown, in some embodiments of the present invention, to reduce the weight of the base plate 104, multiple hollow portions 107 are provided on the base plate 104. This reduces the actual material usage of the base plate 104, thereby effectively reducing the weight of the entire mounting base 100. This helps improve the convenience of installation, movement, and transportation, and reduces labor and material costs. The hollow portions 107 not only reduce the weight of the base plate 104, but also, through proper design and arrangement, maintain sufficient structural strength. The rationally arranged hollow portions 107 on the base plate 104 can form a uniform force distribution, increasing the stability and rigidity of the base plate 104. This ensures that the overall structure of the mounting base 100 is sufficiently stable and robust while maintaining a lighter weight.

[0077] like Figure 1 As shown, in some embodiments of the present invention, a slide rail 103 is provided at the other end of the side plate 105, and the second stop assembly 300 and the mounting base 400 are slidably connected to the other end of the side plate 105. By providing slide rails 103 on both sides of the side plate 105, the range of movement of the second stop assembly 300 and the mounting base 400 is limited, ensuring the stability of the second stop assembly 300 and the mounting base 400 and preventing them from shaking during use, thereby improving the stability and service life of the equipment. Furthermore, the second stop assembly 300 and the mounting base 400 can be quickly adjusted in position on the side plate 105 according to work needs when measuring server chassis of different sizes, thereby completing the work more quickly and accurately and improving the flexibility of use.

[0078] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the mounting base 100 is provided with support feet 108, which are connected to the base plate 104. The support feet 108 enable the mounting base to remain stable during testing of the server chassis 500, thereby improving the accuracy and efficiency of the test. Furthermore, the support feet 108 prevent the mounting base 100 from directly contacting the ground, avoiding wear or damage caused by friction or other external factors, and extending the service life of the server chassis testing device.

[0079] The support leg 108 can be integrally formed with the base plate 104. For example, the support leg 108 and the base plate 104 can be integrally formed by welding. In this way, the integrally formed support leg 108 can avoid additional connecting parts, thereby saving materials and manufacturing costs. Moreover, the integrally formed or welded support leg 108 and the base plate 104 do not require additional connection work, simplifying the production and installation process and reducing safety hazards caused by disassembly. The connection between the integrally formed or welded support leg 108 and the base plate 104 is more stable, less prone to loosening and damage, and improves the stability and service life of the equipment.

[0080] Of course, the connection method between the support leg 108 and the base plate 104 is not limited to this. In other embodiments of this application, for ease of equipment maintenance, the support leg 108 can also be detachably connected to the base plate 104. For example, a limiting hole adapted to the support leg 108 can be opened on the base plate 104, and the support leg 108 can be inserted into the limiting hole to fix it. In this way, if the equipment needs to adjust its height or the support leg 108 needs to be replaced, it can be detachably connected to the base plate 104, making maintenance and replacement more convenient and improving the flexibility and adaptability of the equipment. Specifically, the support leg 108 can be integrally formed with the base plate 104 or a detachable support leg 108, depending on the usage environment and needs.

[0081] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the support foot 108 can be cylindrical, such as a cylindrical support foot 108 or a prismatic support foot 108. Of course, in other embodiments, for aesthetic purposes, the support foot 108 can also be configured in other shapes. In this embodiment, the support foot 108 is preferably cylindrical. Cylindrical support feet 108 are more robust, and due to their structural characteristics, they distribute load more evenly, thus providing greater load-bearing capacity and more stable support for the fixed base 100, preventing the equipment from shaking or tilting during use. Compared to support feet 108 of other shapes, cylindrical support feet 108 are more resistant to wear, thereby extending their service life. Furthermore, cylindrical support feet 108 occupy relatively little space, effectively saving usable space.

[0082] In some embodiments of the present invention, the support foot 108 can be a retractable cylinder, allowing the height or angle of the support foot 108 to be adjusted as needed. This enables the server chassis torsion testing device to adapt to various usage environments and occasions, maintaining optimal working condition, improving the flexibility of testing and increasing work efficiency. Furthermore, when the server chassis torsion testing device is not in use, the support foot 108 can be retracted, facilitating a reduction in the device's size and making it convenient for storage and portability.

[0083] In some embodiments of the present invention, the support feet 108 can be arranged in an array on the base plate 104, which can increase the stability of the base plate 104. Alternatively, in other embodiments of the present invention, the support feet 108 can be a large support platform located at the center of the base plate 104.

[0084] Of course, the arrangement of the support feet 108 is not limited to this. In this embodiment, support feet 108 are provided at all four corners of the base plate 104. The four corner support feet 108 ensure the stability of the base plate 104 under any circumstances, especially when the base plate 104 is bearing heavy loads or subjected to external forces; the four corner supports effectively prevent the base plate 104 from rolling or shaking. Compared to a single large support platform, the design with support feet 108 at all four corners makes it easier to distribute weight evenly, effectively improving the overall load-bearing capacity of the structure. If the ground where the base plate 104 is located is uneven, the design of the four corner support feet 108 allows for easy adjustment to ensure the base plate 104 remains level. Compared to a large support platform, the support feet 108 at the four corners are more compact, occupy less space, and have higher space utilization efficiency; therefore, the arrangement of four corner support feet 108 is preferred in this embodiment.

[0085] The following is combined with Figures 1 to 6 The following describes the usage of the server chassis 500 torsion testing device provided by the present invention through one embodiment. It should be noted that in this embodiment, the first stop assembly 200 has two stop rods 201, and the second stop assembly 300 also has two stop rods 201.

[0086] like Figure 3 and Figure 4 As shown, the server chassis 500 to be tested is first placed in the test chamber 106, so that the bottom surface of the front window of the server chassis 500 covers the first through hole 101 on the base plate 104. Then, the first stop assembly 200 is unscrewed from the first through hole 101, raising the left side of the front window of the chassis by 50 mm, leaving the right side of the front window suspended. Next, the second stop assembly 300 is adjusted to ensure that both stop rods 201 of the second stop assembly 300 abut against the top surface of the rear window edge of the chassis. Then, the position of the mounting base 400 is adjusted so that one displacement sensor 601 is located above the side of the front window that has been raised, and the other is located above the side of the front window that has been suspended. Finally, the difference value read from the displacement difference calculation screen 602 is the torsional strength of the left side of the front window of the server chassis 500.

[0087] Next, the torsional strength of the right side of the front window of the server chassis 500 was tested. The first stop component 200 was used to raise the right side of the front window of the chassis by 50 mm, leaving the left side of the front window suspended in the air. The difference in displacement was read from the calculation screen 602, which represents the torsional strength of the right side of the front window of the server chassis 500.

[0088] Finally, rotate the server chassis 500 horizontally by 180 degrees so that the bottom surface of the rear window of the server chassis 500 covers the first through hole 101 on the base plate 104. Repeat the above process to measure the torsional strength of the rear window of the server chassis 500.

[0089] In related technologies, server chassis come in different sizes, such as 1U, 4U, or 42U. Servers smaller than 4U have poor torsional strength and require significant reinforcement. Server chassis larger than 5U have better strength and generally do not have torsion issues. The server chassis torsion testing device provided by this invention is applicable to server chassis ranging from 1U to 4U, has wide applicability, and is easy to operate.

[0090] This invention measures the torsional displacement difference of a server chassis 500 using a three-point fixation method, effectively assessing the chassis's torsional strength and providing data support for guiding the torsional resistance design of server chassis, protecting internal components such as the motherboard and hard drive from torsional damage. The device is easy to operate and facilitates data processing.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
