Description

Technical Field

[0001] This disclosure relates to the field of fixture technology, and in particular to a safety lock testing fixture. Background Technology

[0002] Currently, users utilize a security lock function when securing their laptops. One end of the security lock is inserted into the laptop's security lock slot, while the other end is wrapped around a fixed object to secure the laptop. The connection strength test between the security lock and the laptop is conducted manually. The laptop is fixed to a lifting platform, and then a 30kg weight is pulled by moving the platform to test whether the security lock meets the 30kg strength standard in five directions (Z+, Z-, Y+, Y-, and X+).

[0003] However, the above testing process has the following main problems: 1) The tester needs to hold the laptop computer by hand during the test, which poses a risk of the mechanical parts breaking and injuring the tester; 2) The test requires a force of 30 kg to be maintained for 10 seconds, and manual holding makes it difficult to ensure the stability and consistency of each operation, resulting in inaccurate test results; 3) Since five directions need to be tested, it is necessary to hold the laptop computer by hand in five different test directions, resulting in extremely low testing efficiency.

Detailed Implementation

[0032] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0033] Firstly, such as Figure 1 As shown, this application provides a security lock testing fixture 1 for testing the connection strength between a security lock 3 and an electronic device 2. The electronic device 2 has a security lock hole, and the security lock 3 is plugged into the security lock hole. The security lock testing fixture 1 includes:

[0034] A force gauge 11 is used to connect to the safety lock 3 to apply a pulling force to the safety lock 3;

[0035] Support plate 12 is used to fix electronic device 2;

[0036] The support frame assembly 13 is rotatably connected to the support plate 12. The support frame assembly 13 and the support plate 12 are configured to cooperate with each other to adjust the direction of the tension between the safety lock 3 and the tension gauge 11, thereby enabling the safety lock 3 to complete the tension test in the Z+ direction, Z- direction, Y+ direction, Y- direction, and X+ direction; wherein, the X+ direction is the direction in which the safety lock 3 is pulled out of the safety lock hole.

[0037] For example, the Z+ direction, Z- direction, Y+ direction, Y- direction, and X+ direction are... Figure 3 direction shown.

[0038] For example, the electronic device 2 of this application includes, but is not limited to, a laptop computer. Taking a laptop computer as an example, it has a security lock hole, and a security lock 3 is plugged into the security lock hole to prevent the laptop computer from being stolen.

[0039] The safety lock test fixture 1 of this application mainly uses a tensile gauge 11, a bearing plate 12, and a support assembly 13 to meet the tensile force testing requirements of the safety lock 3 in five directions: Z+, Z-, Y+, Y-, and X+. This allows for the testing of the connection strength between the safety lock 3 and the electronic device 2. The entire testing process is simple and convenient, ensuring comprehensiveness and accuracy of the results. The safety lock test fixture provided in this application primarily utilizes the principle of rotating a circle around its center at different angles. The support assembly 13 rotates around its axis at different angles to achieve omnidirectional rotation of the fixture, fulfilling the testing requirements of the electronic device in five directions and ensuring comprehensive and accurate test results.

[0040] The safety lock testing fixture of this application eliminates the need for manual intervention during testing, thus removing the risk of personal injury. The test requires a force of 30 kg for 10 seconds, and the fixture ensures the stability and consistency of the testing process, guaranteeing the accuracy of the results. Furthermore, this fixture allows for testing of the safety lock in five directions, achieving comprehensive testing and significantly improving testing efficiency.

[0041] In one possible implementation, such as Figure 1-3 As shown, the support assembly 13 includes: a rotating support 131, which is rotatably connected to the support plate 12;

[0042] The side support 132 is rotatably connected to the first end of the rotating support 131. The side support 132 is provided with a clearance hole 1321, which is used to allow the second end of the rotating support 131 to rotate around the first end of the rotating support 131.

[0043] The clearance hole 1321 is provided with multiple limiting points 1322 at intervals along its circumferential direction. The limiting points 1322 are used to restrict the movement of the second end of the rotating support 131 so that the safety lock 3 can complete the tensile test in the Z+ direction, Z- direction, Y+ direction, Y- direction and X+ direction.

[0044] For example, the rotatable connection between the rotating support 131 and the support plate 12 can be achieved as follows: threaded holes 122 are respectively provided at corresponding positions on the support plate 12 and the rotating support 131, and threaded parts are used to thread the threaded holes 122 on the support plate 12 and the rotating support 131, thereby achieving the rotatable connection between the rotating support 131 and the support plate 12. Of course, the rotatable connection between the rotating support 131 and the support plate 12 can also be achieved using existing known technologies, and no specific limitation is made thereto.

[0045] For example, such as Figure 3As shown, the first end of the rotating support 131 is constructed as a circular shaft and is rotatably connected to the side support 132. The second end of the rotating support 131 can rotate around the rotatable connection point between the first end of the rotating support 131 and the side support 132 and rotates within the clearance hole 1321.

[0046] For example, the center lines connecting multiple limiting points 1322 and the clearance hole 1321 are set at 0°, 90°, 180°, and 270° respectively. Figure 2 As shown, the clearance hole 1321 has an arc structure, and the center of the clearance hole 1321 is the rotational connection point between the first end of the rotating support 131 and the side support 132. There are four limiting points 1322, and the lines connecting these four limiting points to the center of the clearance hole 1321 are set at 0°, 90°, 180° and 270° respectively, thereby completing the connection strength test between the electronic device 2 and the safety lock 3 in five directions.

[0047] For example, such as Figure 3 As shown, the limiting point 1322 is a limiting slot opened on the clearance hole 1321, and the width of the limiting slot is greater than the width of the clearance hole 1321.

[0048] For example, the second end of the rotating support 131 is movably accommodated in the clearance hole 1321 and is connected to the spring cover 133 by a spring at the end position. The width of the spring cover 133 is greater than the width of the clearance hole 1321 and less than the width of the limiting groove.

[0049] like Figure 2 As shown, the second end of the rotating support 131 is located within the clearance hole 1321, and the second end of the rotating support 131 is connected to the spring cover 133 via a spring. The width of the spring cover 133 is greater than the width of the clearance hole 1321 and less than the width of the limiting slot. Before the second end of the rotating support 131 is housed in the clearance hole 1321 and rotates around its first end to the limiting slot, the spring cover 133 is located outside the side support 132 and rotates synchronously with the second end of the rotating support 131. The spring is in a stretched state and has elastic force. When the second end of the rotating support 131 rotates to the limiting slot, the spring cover 133 is pulled by the spring and engages in the limiting slot, so that the second end of the rotating support 131 is fixed in the limiting slot. When it is necessary to rotate the second end of the rotating support 131 to the next limiting slot, simply pull the spring cover 133 outward to the outside of the side support 132. The rotating support 131 will simultaneously drive the spring cover 133 to rotate to the next limiting slot. Under the action of the spring, the spring cover 133 will be pulled to engage in the limiting slot, thereby fixing the second end of the rotating support 131 on the limiting slot.

[0050] In one possible implementation, such as Figure 3As shown, a fixing block 121 is provided on the carrier plate 12, and the fixing block 121 is used to fix the electronic device 2.

[0051] For example, such as Figure 3 As shown, the fixing block 121 has an L-shaped slot structure. When the electronic device 2 is placed on the support plate 12, the fixing block 121 fixes the electronic device 2 to limit its displacement. Of course, the fixing block 121 can also use other existing known methods to fix the electronic device 2. For example, the fixing block 121 can be set as a block structure and can be movably installed on the support plate 12 by screws. When it is necessary to fix the electronic device 2 on the support plate 12, the four sides of the electronic device 2 can be fixed to the support plate 12 by the fixing block 121 and screws. In order to avoid damage to the electronic device by the fixing block, an anti-slip rubber layer is provided on the contact surface between the fixing block and the electronic device. While maintaining close contact with the electronic device, it can also prevent damage to the outer shell of the electronic device while fixing it.

[0052] For example, such as Figure 3 As shown, the bearing plate 12 and the rotating support frame 131 are provided with clearance openings 1211 at corresponding positions to avoid the connection between the safety lock 3 and the tension gauge 11.

[0053] In one possible implementation, such as Figure 1-3 As shown, the safety lock test fixture 1 also includes a base 14, on which a support assembly 13 is mounted. Specifically, a side support 132 is fixedly mounted on the base 14.

[0054] In one possible implementation, such as Figure 3 As shown, the safety lock test fixture 1 also includes a force gauge bracket 15, which is used to mount the force gauge 11 and is slidably connected to the base 14.

[0055] For example, a sliding groove 141 is provided on the base 14, and the tension gauge support 15 is slidably connected to the sliding groove 141 to adjust the perpendicularity between the tension gauge 11 and the safety lock 3. For example, the bottom of the tension gauge support 15 and the sliding groove 141 can be connected by bolt threads. Specifically, since only five directions of testing are required for the safety lock, multiple threaded holes can be opened at intervals on the sliding groove 141, and threaded holes can also be opened on the bottom of the tension gauge support 15. Then, according to the position of the second end of the rotating support 131 engaged at the limiting point, the position of the tension gauge support 15 on the sliding groove 141 is adaptively adjusted, and then the threaded holes of the two are connected by bolts to fix the tension gauge support 15 and the sliding groove 141. Thus, the perpendicularity between the safety lock 3 and the tension gauge 11 can be guaranteed for tension tests in different directions, thereby ensuring the accuracy of the test.

[0056] For example, to further ensure the stability of the testing process and the accuracy of the test results, the force gauge 11 is movably mounted on the force gauge support 15. Exemplarily, an elongated hole (not shown in the figure) is provided along the length of the force gauge support 15, and a threaded hole is provided on the force gauge. A bolt passes through the elongated hole and its end is threadedly connected to the threaded hole of the force gauge 11, thereby allowing adjustment of the mounting position of the force gauge 11 on the force gauge support 15. When the safety lock needs to test tensile forces in different directions, the mounting position of the force gauge 11 on the force gauge support 15 can be adaptively adjusted.

[0057] Taking electronic device 2 as a laptop computer as an example, the following is a detailed description of the tensile test of the security lock test fixture 1 of this application on the laptop computer in five directions:

[0058] 1) Testing in the Z+ direction:

[0059] like Figure 4 As shown, along the counterclockwise direction of the clearance hole 1321, the four limiting points 1322 on the clearance hole 1321 are sequentially set as the first limiting point 13221, the second limiting point 13222, the third limiting point 13223, and the fourth limiting point 13224.

[0060] Rotate the second end of the rotating bracket 131 around its first end until the spring cover 133 at the second end of the rotating bracket 131 engages at the first limiting point 13221. The laptop is positioned facing the force gauge 11, and the rotating bracket 131 is parallel to the base 14. Connect the tension end of the force gauge 11 to the safety lock 3, so that the force gauge 11 applies tension in the Z+ direction, completing the tension test of the safety lock 3 in the Z+ direction, and thus completing the connection strength test between the laptop and the safety lock 3 in the Z+ direction.

[0061] (ii) Testing in the Z-direction:

[0062] like Figure 5 As shown, the spring cover 133 is pulled outward to the outside of the side support 132, and then rotated 180° counterclockwise, so that the second end of the rotating support 131 rotates in the clearance hole 1321 and synchronously drives the spring cover 133 to rotate until it moves to the third limiting point 13223. Since the third limiting point 13223 (limiting slot) is larger than the width of the spring cover 133, the spring cover 133 is pulled under the action of the spring to make the spring cover 133 engage in the third limiting point 13223, thereby fixing the rotating support 131 on the side support 132.

[0063] like Figure 5As shown, the bearing plate 12 on the rotating support 131 and the laptop computer it carries are in a direction away from the tension gauge 11. The tension end of the tension gauge 11 is connected to the safety lock 3 through the clearance port 1211, thereby completing the tension test of the safety lock 3 in the Z-direction, and then completing the connection strength test between the laptop computer and the safety lock 3 in the Z-direction.

[0064] (iii) Testing in the Y+, Y-, and X+ directions:

[0065] like Figure 6 As shown, referring to the test methods in the Z+ and Z- directions described above, the spring cover 133 is pulled outward to the outside of the side support 132, so that the second end of the rotating support 131 rotates in the clearance hole 1321 and synchronously drives the spring cover 133 to rotate until it moves to the second limit point 13222 or the fourth limit point 13224, so that the spring cover 133 is engaged in the second limit point 13222 or the fourth limit point 13224, thereby enabling the safety lock 3 to complete the tensile force test in the Y- and Y+ directions, thus completing the connection strength test between the laptop and the safety lock 3 in the Y+ and Y- directions.

[0066] like Figure 7 As shown, the second end of the rotating bracket 131 is rotated within the clearance hole 1321, and the spring cover 133 is rotated synchronously until it moves to the fourth limit point 13224, so that the spring cover 133 is engaged within the fourth limit point 13224. Then, the support plate 12 is rotated so that the security lock hole of the laptop computer and the security lock on the support plate 12 are set along the X+ direction. The tension end of the tension gauge 11 is connected to the security lock 3, so that the security lock 3 completes the tension test in the X+ direction, thereby completing the connection strength test between the laptop computer and the security lock 3 in the X+ direction.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0068] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
