Description

Technical Field

[0001] This invention relates to the field of thermal instruments, specifically to a thermal performance testing device. Background Technology

[0002] A thermal performance tester is a device used to measure the calorific value of fuels or other materials. It integrates precision sensors, signal processing circuits, microprocessors, and power supply units. The back of the thermal performance tester has multiple functional interfaces such as thermocouple input, pressure detection, and data communication.

[0003] In related technologies, during use, because the interface on the back of the instrument is exposed to the working environment for a long time, foreign objects are prone to enter the interface when the thermal performance measuring instrument is transported, which can easily cause poor contact or electrical short circuit. This not only fails to guarantee the stability of the equipment, but also increases maintenance costs and the risk of failure. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a thermal performance testing device that can shield the interface and has a long service life.

[0006] The thermal performance testing device according to an embodiment of the present invention includes: a testing box having an interface for connecting an instrument; a shielding assembly disposed on the testing box, the shielding assembly having a first state and a second state, wherein in the first state the shielding assembly is unfolded to shield the interface, and in the second state the shielding assembly is retracted to allow the interface to connect to the instrument; and a support assembly including a first support member and a second support member, both disposed below the testing box and spaced apart along the length of the testing box, the first support member being disposed on the side adjacent to the interface, the first support member extending and retracting in a vertical direction, wherein in the first state the first support member and the second support member are at the same height to support the testing box, and in the second state the first support member extends to lift the testing box.

[0007] The thermal performance testing device of this invention includes a shielding component. When the testing chamber is in operation, the shielding component retracts to ensure normal operation. When the testing chamber is not in operation, the shielding component unfolds to cover the back interface of the testing chamber, preventing external dust, moisture, and debris from entering the interface. This effectively avoids faults such as poor contact and short circuits caused by interface contamination, extends the service life of the interface, and ensures the stability and reliability of the testing device. It also facilitates instrument connection and testing work for operators, improving testing efficiency. Furthermore, a first support component is provided. In the first state, the first support component evenly distributes the weight of the testing chamber, providing stable and reliable support to ensure the stability of the testing chamber and the accuracy of test data and the smoothness of the process. In the second state, the first support component allows the testing chamber to be tilted and adjusted, providing convenient operating space for personnel during inspection, maintenance, special testing operations, or instrument connection, improving work efficiency and accuracy.

[0008] In some embodiments, the shielding assembly includes: a take-up shaft disposed on the outer peripheral surface of the detection box and rotatable relative to the take-up shaft in a vertical direction; a shielding member, one end of which is wound around the take-up shaft; and a driving member disposed on the detection box and movable along the circumference of the detection box, the driving member being connected to the other end of the shielding member. In a first state, the shielding member is retracted into the take-up shaft, and in a second state, the shielding member pulls the shielding member to move in order to shield the interface.

[0009] In some embodiments, the outer peripheral surface of the detection box is provided with a guide shell, the guide shell extends circumferentially along the detection box, and the upper end of the drive member is disposed inside the guide shell and moves relative to the guide shell along the extension direction of the guide shell.

[0010] In some embodiments, the driving member includes a housing, a driving rod, a slider, and a first elastic member. The slider is disposed within the guide housing and is movable along the extending direction of the guide housing. The lower end of the driving rod passes through the housing, and the upper end of the driving rod passes through the slider. The driving rod is movable relative to the slider in a vertical direction between a first position and a second position. In the first state, the driving rod is located at the first position, and the upper end of the driving rod is located within the slider. In the second state, the driving rod is located at the second position, and the upper end of the driving rod passes through the slider and is disposed within the guide housing to restrict the movement of the slider. The elastic member is disposed within the housing and located between the housing and the driving rod. The first elastic member has an elastic force that drives the driving rod to move upward.

[0011] In some embodiments, the thermal performance testing device further includes an alarm element disposed within the guide housing and cooperating with the first support member, such that the alarm element issues an alarm when the first support member extends.

[0012] In some embodiments, the alarm component includes: a metal bell disposed within the guide housing; a striking block having a mounting groove on the slider, the striking block being disposed within the mounting groove and movable along the length direction of the mounting groove; and a second elastic member disposed within the mounting groove, with both ends of the second elastic member connected to the striking block and the mounting groove respectively, the second elastic member having an elastic force that drives the striking block to move toward the metal bell, so that when the first support member extends, the slider drives the striking block to move to the metal bell and strike the metal bell.

[0013] In some embodiments, the first support member includes: a mounting frame disposed at the bottom of the detection box; and a drive frame disposed at the bottom of the detection box and passing through the mounting frame. The drive frame has a first mating part, and the mounting frame has a second mating part. The first mating part and the second mating part cooperate with each other. The drive frame is connected to the shielding component so that the shielding component drives the drive frame to move so that the drive frame drives the detection box to move in the vertical direction.

[0014] In some embodiments, at least one of the first mating portion and the second mating portion is a groove that extends in a vertical direction, and at least one of the first mating portion and the second mating portion is a protrusion that passes through the groove and is movable within the groove.

[0015] In some embodiments, the groove includes a first segment, a second segment, and a third segment. The first segment and the second segment are spaced apart along the length of the detection box. The first segment extends from top to bottom and is inclined away from the second segment. The second segment extends from top to bottom and is inclined away from the first segment. The third segment extends along the length of the detection box, and the two ends of the third segment are respectively connected to the upper ends of the first segment and the second segment.

[0016] In some embodiments, there are multiple interfaces, and the multiple interfaces are arranged in multiple rows at intervals along the vertical direction, with each row including a number of interfaces at intervals along the length direction of the detection box. Attached Figure Description

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] The thermal performance testing apparatus 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0030] like Figure 1-10 As shown, the thermal performance testing device 100 according to an embodiment of the present invention includes a testing box 1, a shielding component 2, and a support component 3.

[0031] The testing box 1 is equipped with an interface 11 for connecting instruments. Specifically, as shown... Figures 1-4 As shown, the test chamber 1 is a thermal performance tester with a display screen and control buttons on the front. The display screen can display various data information acquired during the test in real time and accurately, such as key parameters such as temperature, pressure, and flow rate, providing operators with intuitive test result feedback. The control buttons facilitate the input of various operation commands by the operator to the test device, such as starting the test, stopping the test, and setting parameters, improving the convenience and flexibility of operation.

[0032] The back of the testing box 1 has multiple interfaces 11. These interfaces 11 are standardized according to different testing needs and instrument types, ensuring compatibility with various types of testing instruments and guaranteeing the versatility and expandability of the device. A lifting handle 13 is fixedly connected to the top of the testing box 1, allowing operators to move the testing device to different testing positions. A support base is fixedly connected to the bottom of the testing box 1, providing basic support for the entire device and ensuring its stability during testing, thus reducing measurement errors caused by shaking.

[0033] The shielding component 2 is mounted on the detection box 1. The shielding component 2 has a first state and a second state. In the first state, the shielding component 2 is unfolded to shield the interface 11. In the second state, the shielding component 2 is retracted to allow the interface 11 to connect to the instrument. Specifically, as shown... Figures 1-4 As shown, the shielding component 2 is installed on the testing box 1. In the first state, the shielding component 2 is in the unfolded state, shielding the interface 11 on the back of the testing box 1. This effectively prevents dust, moisture, debris, etc. from the external environment from entering the interface 11, avoiding malfunctions such as poor contact and short circuits caused by interface 11 contamination, thereby extending the service life of the interface 11 and ensuring the stability and reliability of the testing device. In the second state, the shielding component 2 is retracted, providing convenient space for the connection operation between the interface 11 and the instrument. Operators can connect the testing instrument to the interface 11 to carry out various testing tasks.

[0034] The support assembly 3 includes a first support member 31 and a second support member 32. Both the first support member 31 and the second support member 32 are located below the detection box 1 and spaced apart along the length of the detection box 1. The first support member 31 is positioned on the side adjacent to the interface 11. In the first state, the first support member 31 and the second support member 32 are at the same height, so that they support the detection box 1. In the second state, the first support member 31 extends to lift the detection box 1. Specifically, as... Figure 6 and Figure 7 As shown, the first support member 31 and the second support member 32 are positioned below the testing box 1 and are spaced apart along the front-to-back direction, providing uniform and stable support for the testing box 1. The first support member 31 is located at the rear end and can extend and retract vertically. In the first state, the first support member 31 and the second support member 32 are at the same height, ensuring that they evenly distribute the weight of the testing box 1, providing stable and reliable support. This ensures that the testing box 1 remains stable during normal operation, preventing swaying or tilting caused by uneven support, thereby guaranteeing the accuracy of the testing data and the smooth progress of the testing process.

[0035] In the second state, the first support member 31 will extend, increasing its length compared to the initial state. As the first support member 31 extends, it will gradually raise one side of the testing box 1, which was originally at the same height as the second support member 32. This allows the testing box 1 to be tilted at a certain angle according to actual work needs. For example, when it is necessary to inspect, maintain, or perform special testing operations on specific parts inside the testing box 1, or when connecting the instrument to the interface 11 of the testing box 1, raising the testing box 1 by extending the first support member 31 can provide more convenient operating space for the staff, improving work efficiency and operational accuracy.

[0036] The thermal performance testing device 100 of this invention includes a shielding component 2. When the testing chamber 1 is working, the shielding component 2 is retracted to ensure the normal operation of the testing chamber 1. When the testing chamber 1 is not working, the shielding component 2 is unfolded to shield the back interface 11 of the testing chamber 1, preventing external dust, moisture, and debris from entering the interface 11. This effectively avoids faults such as poor contact and short circuits caused by interface 11 contamination, extends the service life of the interface 11, and ensures the stability and reliability of the testing device. At the same time, it facilitates the connection of instruments by operators to carry out testing work, improving testing efficiency. In addition, a first support member 31 is provided. In the first state, the first support member 31 can evenly distribute the weight of the testing chamber 1, providing stable and reliable support to ensure the stability of the testing chamber 1 and ensure accurate test data and smooth process. In the second state, the first support member 31 can tilt and adjust the testing chamber 1, providing convenient operating space for staff when inspecting, maintaining, performing special testing operations, or connecting instruments, improving work efficiency and accuracy.

[0037] In some embodiments, the shielding assembly 2 includes a winding shaft 21, a shielding member 22, and a driving member 23.

[0038] The take-up shaft 21 is disposed on the outer peripheral surface of the detection box 1, and the take-up shaft 21 is rotatable relative to the detector in the vertical direction. Specifically, as shown in the figure... Figures 1-4 As shown, the outer circumferential surface of the detection box 1 is provided with an extension seat 14, and the winding shaft 21 is rotatably mounted on the extension seat 14. A coil spring is provided between the winding shaft 21 and the extension seat 14. The coil spring is connected to the winding shaft 21 and the extension seat 14 respectively, and the coil spring has an elastic force that drives the winding shaft 21 to twist.

[0039] In some embodiments, one end of the blocking member 22 is wound around the take-up shaft 21, and the driving member 23 is disposed on the detection box 1 and movable along the circumference of the detection box 1. The driving member 23 is connected to the other end of the blocking member 22. In a first state, the blocking member 22 is retracted into the take-up shaft 21. In a second state, the blocking member 22 is pulled to move in order to block the interface 11. Specifically, as Figures 1-4 As shown, the shielding member 22 is a protective cloth. One end of the shielding member 22 is wound around the take-up shaft 21. The driving member 23 is set on the outer peripheral surface of the detection box 1 and moves along the outer peripheral surface of the detection box 1. The other end of the shielding member 22 is connected to the driving member 23. In the second state, the driving member 23 can pull the shielding member 22 to unfold from the take-up shaft 21, so that the shielding member 22 covers the interface 11 of the detection box 1, effectively shielding the interface 11. At the same time, as the take-up shaft 21 is pulled and rotated, the coil spring connected to it begins to store elastic potential energy. In the first state, the coil spring releases the elastic potential energy stored before to drive the take-up shaft 21 to reverse. The reversal of the take-up shaft 21 causes the shielding member 22 wound on it to be stored, so that the shielding member 22 is stored inside the take-up shaft 21, and the interface 11 of the detection box 1 is exposed, which facilitates the staff to perform related operations.

[0040] In some embodiments, a guide shell 12 is provided on the outer peripheral surface of the detection box 1. The guide shell 12 extends circumferentially along the detection box 1, and the upper end of the driving member 23 is disposed within the guide shell 12 and moves relative to the guide shell 12 along the extending direction of the guide shell 12. Specifically, as shown... Figures 1-4 As shown, the guide shell 12 is disposed on the outer peripheral surface of the detection box 1 and located at the upper end of the detection box 1. The drive component 23 is disposed inside the guide shell 12, so that the drive component 23 moves along the set route through the guide shell 12, avoiding the drive component 23 from deviating, shaking or deviating from the predetermined trajectory during the movement.

[0041] In some embodiments, the driving member 23 includes a housing 231, a driving rod 232, a slider 233, and a first elastic member 234. The slider 233 is disposed within the guide housing 12 and is movable along the extending direction of the guide housing 12. The lower end of the driving rod 232 passes through the housing 231, and the upper end of the driving rod 232 passes through the slider 233. The driving rod 232 is movable relative to the slider 233 in a vertical direction between a first position and a second position. In a first state, the driving rod 232 is located in the first position, and the upper end of the driving rod 232 is located within the slider 233. In a second state, the driving rod 232 is located in the second position, and the upper end of the driving rod 232 passes through the slider 233 and is disposed within the guide housing 12 to restrict the movement of the slider 233. The elastic member is disposed within the housing 231 and is located between the housing 231 and the driving rod 232. The first elastic member 234 has an elastic force that drives the driving rod 232 to move upward. Specifically, as shown in the figure... Figure 5 As shown, the housing 231 is a cylindrical shape extending vertically, and the drive rod 232 is a cylindrical shape extending vertically with its lower end passing through the housing 231. The drive rod 232 can move vertically within the housing 231. The first elastic element 234 is a compression spring that passes through the housing 231 and is located below the drive rod 232. The upper and lower ends of the first elastic element 234 are respectively connected to the lower end of the drive rod 232 and the bottom of the housing 231. The slider 233 is slidably connected within the guide housing 12. The upper end of the drive rod 232 passes through the slider 233 and can move vertically between a first position and a second position within the slider 233. In the first state, the drive rod 232 moves downward to the first position, at which time the upper end of the drive rod 232 is located within the slider 233, so that the drive rod 232 and the slider 233 form a whole and can move freely within the guide housing 12. At the same time, the first elastic element 234 is compressed to store elastic potential energy, at which point the driving element 23 can drive the blocking element 22 to move.

[0042] In the second state, when the drive member 23 moves to the appropriate position, the drive rod 232 moves upward to the second position under the action of the first elastic member 234. At this time, the upper end of the drive rod 232 passes through the slider 233 and is inserted into the guide shell 12 to restrict the movement of the slider 233, thereby locking the position of the drive rod 232 and achieving a reliable blocking effect.

[0043] In some embodiments, the first support 31 includes a mounting bracket 311 and a drive bracket 312.

[0044] Mounting bracket 311 is located at the bottom of the detection box 1, and driving bracket 312 is located at the bottom of the detection box 1 and passes through the mounting bracket 311. The driving bracket 312 has a first mating part, and the mounting bracket 311 has a second mating part. The first and second mating parts cooperate. The driving bracket 312 is connected to the shielding assembly 2 so that the shielding assembly 2 drives the driving bracket 312 to move, thereby allowing the driving bracket 312 to drive the detection box 1 to move vertically. Specifically, as shown... Figures 5-8 As shown, the mounting bracket 311 is located at the bottom of the test box 1. The mounting bracket 311 is provided with a vertical slide groove extending in the up and down direction. The test box 1 is provided with a slider 233 that cooperates with the slide groove. The slider 233 can move in the up and down direction within the slide groove, so that the test box 1 can move up and down relative to the mounting bracket 311, while ensuring that the test box 1 will not detach from the mounting bracket 311 during the movement.

[0045] The drive frame 312 is a U-shaped plate. The drive frame 312 passes through the mounting frame 311 and is connected to the drive component 23 of the shielding assembly 2. The drive frame 312 is provided with a first mating part, and the mounting frame 311 is provided with a second mating part that mates with the first mating part. The drive component 23 pulls the mounting frame 311 to move in the left and right direction. The first mating part and the second mating part mate, causing the drive frame 312 to move upward so as to drive the detection box 1 to move upward.

[0046] In some embodiments, at least one of the first mating part and the second mating part is a groove 313 extending in the vertical direction, and at least one of the first mating part and the second mating part is a protrusion 314 passing through the groove 313 and movable within the groove 313. Thus, the protrusion 314 slides in the groove 313 in the vertical direction to drive the drive frame 312 to move in the vertical direction, thereby driving the detection box 1 to move in the vertical direction.

[0047] In some embodiments, the groove 313 includes a first segment 3131, a second segment 3132, and a third segment 3133. The first segment 3131 and the second segment 3132 are spaced apart along the length of the detection box 1. The first segment 3131 extends from top to bottom and is inclined away from the second segment 3132. The second segment 3132 extends from top to bottom and is inclined away from the first segment 3131. The third segment 3133 extends along the length of the detection box 1, and its two ends are connected to the upper ends of the first segment 3131 and the second segment 3132, respectively. Specifically, as shown... Figure 8 As shown, the first segment 3131 and the second segment 3132 are spaced apart in the left-right direction. The first segment 3131 extends downwards and tilts to the left, and the second segment 3132 also extends downwards and tilts to the right. The third segment 3133 extends in the left-right direction, and the left and right ends of the third segment 3133 are connected to the upper ends of the first segment 3131 and the upper ends of the second segment 3132, respectively.

[0048] As the drive member 23 pulls the drive frame 312 to move in the left-right direction, the protrusion 314 slides within the first segment 3131, causing the drive frame 312 to move upwards. When the protrusion 314 slides to the third segment 3133, since the third segment 3133 extends horizontally, the drive frame 312 will no longer continue to move upwards. If the drive member 23 continues to move, the protrusion 314 slides downwards within the second segment 3132, thereby causing the drive frame 312 to move downwards.

[0049] In some embodiments, there are multiple interfaces 11, and the multiple interfaces 11 are arranged in multiple rows at intervals along the vertical direction. Each row includes a plurality of interfaces 11 spaced apart along the length direction of the detection box 1. Specifically, as shown in the figure Figures 1-4 As shown, the interfaces 11 are arranged in multiple rows with spacing along the vertical direction. Each row includes several interfaces 11 arranged with spacing along the horizontal direction, so that multiple interfaces 11 can be connected to multiple devices at the same time to achieve parallel detection.

[0050] In some embodiments, such as Figure 9 and Figure 10 As shown, the thermal performance testing device 100 also includes an alarm element 4, which is located inside the guide shell 12 and cooperates with the first support member 31. The alarm element 4 sounds an alarm when the first support member 31 extends. Thus, when the first support member 31 extends to its maximum length, the alarm element sounds an alarm to position the first support member 31, facilitating subsequent operation of the drive member 23 by the operator and facilitating the adjustment of the tilt angle of the testing box 1, thereby increasing work efficiency.

[0051] In some embodiments, the alarm element 4 includes a metal bell 41, a striking block 42, and a second elastic element 43.

[0052] A metal bell 41 is disposed within the guide housing 12, and a mounting groove is provided on the slider 233. A striking block 42 is disposed within the mounting groove and is movable along the length of the through hole. Specifically, as shown... Figure 9 and Figure 10 As shown, the guide shell 12 has a through hole, the metal bell 41 is fixed in the through hole, the slider 233 has a mounting groove, the striking block 42 is spherical and is set in the mounting groove, and the striking block 42 can move along the length of the mounting groove in the mounting groove.

[0053] The second elastic element 43 is disposed in the mounting groove, and its two ends are respectively connected to the striking block 42 and the mounting groove. The second elastic element 43 has an elastic force that drives the striking block 42 to move toward the metal bell 41, so that when the first support 31 extends, the slider 233 drives the striking block 42 to move toward the metal bell 41 and strike the metal bell 41. Specifically, as Figure 10 As shown, the second elastic element 43 is a compression spring. The second elastic element 43 is installed in the through hole and its two ends are respectively connected to the bottom of the mounting groove and the striking block 42. The second elastic element 43 has an elastic force that drives the striking block 42 to move outward from the mounting groove. When the slider 233 moves on the guide shell 12, the striking block 42 is located in the mounting groove. When the striking block 42 moves to the position of the through hole, the striking block 42 moves outward from the through hole under the action of the second elastic element 43 to strike the metal bell 41, causing the metal bell 41 to vibrate and sound an alarm.

[0054] The following is based on the appendix Figures 1-10Specifically, the thermal performance testing device 100 of this embodiment includes a shielding assembly 2 and a testing box 1. The front of the testing box 1 has a display screen and control buttons, and the back of the testing box 1 has multiple interfaces 11. A lifting handle 13 is fixedly connected to the top of the testing box 1, and a mounting base is fixedly connected to the bottom of the testing box 1. A support leg is fixedly connected to the bottom of the mounting base. A guide shell 12 is fixedly connected to the left side of the lifting handle 13, and an extension seat 14 is fixedly connected to the right side of the lifting handle 13. A winding shaft 21 is rotatably connected inside the extension seat 14, and a coil spring is fixedly connected to the outside of the winding shaft 21. The end of the coil spring away from the winding shaft 21 is fixedly connected to the extension seat 14, thus forming a complete elastic recovery system. A shielding component is provided outside the winding shaft 21. 22. The shield 22 contacts the test box 1. The shield 22 is made of wear-resistant and anti-static material and can completely cover all the interfaces 11 on the back of the test box 1. The end of the shield 22 away from the winding shaft 21 is fixedly connected to a pull rope. There are two pull ropes, which are symmetrically distributed to ensure uniform force. The end of the pull rope away from the shield 22 is fixedly connected to a drive component 23. With the cooperation of the shield 22 and the coil spring, the interface 11 is elastically covered. Through the coordinated cooperation of the shield 22 and the coil spring, the interface 11 is fully elastically covered and protected. In the non-use state, it can effectively shield all interfaces 11 and prevent foreign objects from entering the interior of the interface 11, fundamentally avoiding poor contact or electrical short circuits, and significantly improving the stability and service life of the equipment.

[0055] The slider 233 is fixedly connected to the top of the drive component 23 and slidably connected to the inner wall of the guide shell 12. A drive rod 232 is slidably connected to the inner wall of the drive component 23. A first elastic element 234 is fixedly connected between the bottom of the drive rod 232 and the drive component 23. A pin is fixedly connected to the top of the drive rod 232 and slidably connected inside the slider 233. A handle 24 is fixedly connected to the outside of the drive rod 232. The surface of the handle 24 is machined with anti-slip texture, which significantly increases the friction during operation. Through the linkage design between the handle 24 and the drive rod 232, the operator can quickly release the pin from locking the drive component 23 by pressing down with one hand, greatly facilitating the opening and closing of the cover 22. By moving the handle 24 down, the drive component 23 can be precisely limited to different positions, providing convenience for subsequent adjustment of the tilt angle of the detection box 1.

[0056] The guide shell 12 has through holes at positions corresponding to the insertion post, and the insertion post is slidably connected within these through holes. Notably, there are three through holes, each corresponding to one of the three connecting holes 121, which reliably limits and fixes the drive component 23 as it moves to different distances. This multi-position limiting design not only effectively limits the drive component 23 when it reaches its maximum distance but also securely locks it after adjusting the tilt angle of the detection box 1, ensuring the stability of the drive component 23 during operation and completely preventing accidental movement. The multiple through holes on the guide shell 12 provide users with flexible operating options, allowing for phased limiting of the moved drive component 23 at different positions, providing a good operational basis for adjusting the instrument angle.

[0057] The drive component 23 has a through groove at the position corresponding to the handle 24, and the handle 24 is slidably connected in the through groove. This design allows the drive component 23 to move up and down smoothly in the through groove, thereby driving the insertion post to complete a precise lifting and lowering action, and provides convenience for quickly releasing the limit on the drive component 23.

[0058] In use, the user first drives the entire shielding assembly 2 by lowering and pulling the handle 24. This action causes the drive component 23 to move smoothly along a preset trajectory, while the pull rope pulls the shielding component 22 gradually unfolds under tension. During this process, the reel 21 rotates and releases the shielding component 22, allowing it to completely cover the back interface 11 area of ​​the detection box 1. The slider 233 slides to its maximum distance on the inner wall of the guide shell 12, ensuring that the drive component 23 reaches the predetermined position. At this time, the shielding component 22 forms a tight barrier, effectively isolating foreign objects from contact with the interface 11, fundamentally avoiding the risk of poor contact or electrical short circuit. When it is necessary to fix the shielding component 22, moving the handle 24 upwards can release the first elastic element 234 from its compressed state. The drive rod 232 and the insertion post move upwards under the action of the reset mechanism, and the insertion post slides precisely into the through hole of the guide shell 12, completing the mechanical locking of the slider 233 and the drive component 23, ensuring that the shielding component 22 maintains a stable covering state during transportation. When using the testing box 1, the user places it on a table, holds the handle 24 and moves it downwards, disengaging the insertion post from the through-hole of the guide shell 12 and releasing the restriction on the drive component 23. Then, the user slowly moves the handle 24 backwards; the elastic restoring force of the coil spring causes the shielding component 22 to retract in an orderly manner, gradually exposing the interface 11 area. The multiple through-holes on the guide shell 12 allow the user to perform phased restrictions on the moved drive component 23 at different positions, providing a flexible operational basis for subsequent instrument angle adjustments. The entire operation is achieved through precise mechanical coordination. The downward movement of the handle 24 first releases the locking state of the insertion post, and then the movement of the drive component 23 causes the shielding component 22 to unfold smoothly. The coil spring provides appropriate tension throughout the process, ensuring that the shielding component 22 can fully unfold to cover the interface 11 and that it can smoothly reset when retraction is needed. The design of multiple restriction points allows the operator to stop the drive component 23 in different positions according to actual needs, providing greater flexibility for subsequent operations.

[0059] The drive frame 312 is fixedly connected to the bottom of the detection box 1. The drive frame 312 is equipped with an adjustment component 315, which achieves precise adjustment of the instrument angle through a multi-stage linkage mechanism.

[0060] The adjustment assembly 315 includes guide posts 3151, which are fixedly connected to the inner wall of the drive frame 312. Two guide posts 3151 are symmetrically arranged on the inner wall of the drive frame 312. A support plate 3152 is slidably connected to the outside of the guide posts 3151 and is also slidably connected to the inner wall of the drive frame 312. Two lifting legs 3153 are fixedly connected to the bottom of the support plate 3152, symmetrically arranged at the bottom of the support plate 3152. These two legs together form the support point of the instrument. Extension blocks 3154 are fixedly connected to both ends of the support plate 3152. The extension blocks 3154 have specially shaped grooves 313 inside, and protrusions 314 are slidably connected inside the grooves 313. An elastic rope 3155 is fixedly connected between the front of the drive frame 312 and the second support member 32. A pull plate 3156 is connected to the drive unit 23, which is connected to the pull plate 3156. With the cooperation of the lifting leg 3153, the test box 1 is stably supported. With the cooperation of the groove 313, the extension block 3154 can be lifted in sections. When the interface 11 is removed, the back of the test box 1 can be raised, which facilitates the subsequent insertion of the connector. After the connector is inserted, as the drive frame 312 continues to move, the lifting leg 3153 can move upward, which makes it easier for the front of the test box 1 to be raised. This allows the user to observe the display screen on the front of the test box 1 and adjust its tilt angle multiple times according to the usage process of the test box 1, increasing the convenience of the test box 1. With the cooperation of the elastic rope 3155, the drive frame 312 can be kept close to the drive unit 23 to prevent the drive frame 312 from moving accidentally. With the cooperation of the pull plate 3156, the drive frame 312 can be reset with the drive unit 23, which facilitates the stable placement of the test box 1.

[0061] The drive frame 312 has a through groove at the corresponding position of the lifting leg 3153, and the lifting leg 3153 is slidably connected in the through groove. This guide mechanism ensures that the lifting leg 3153 maintains a stable movement trajectory during the lifting process, thereby achieving precise adjustment of the tilt angle of the detection box 1.

[0062] A through slot is provided inside the drive frame 312 at a corresponding position, and the drive frame 312 is slidably connected in the through slot. This design ensures that the drive frame 312 can move smoothly, providing a reliable guiding basis for subsequent height adjustment of the extension block 3154, and ensuring the operating accuracy and reliability of the entire adjustment system.

[0063] In use, the test box 1 is lifted by holding the lifting handle 13 with one hand and moving it by pulling the handle 24 with the other hand. After the interface 11 is unblocked, the drive component 23 comes into contact with the drive frame 312. As the drive component 23 continues to move, it pushes the drive frame 312 to move, which in turn causes the protrusion 314 to continue to move. As the protrusion 314 slides inside the groove 313, it comes into contact with the top plane of the groove 313. At this time, the extension block 3154 moves down a certain distance, which causes the support plate 3152 and the lifting leg 3153 to move down a certain distance, thus causing the back of the test box 1 to tilt up. After the drive component 23 is limited, the drive frame 312 is kept close to the drive component 23 with the help of the elastic rope 3155, which prevents the drive frame 312 from moving accidentally. Because the back of the test box 1 tilts up, it is convenient for the user to plug in the connector. After the connection work of the connector is completed, the limit of the drive component 23 is released and the drive component 23 is moved to allow the protrusion 314 to continue moving inside the groove 313 until the protrusion 314 contacts the bottom plane of the groove 313. At this time, the groove 313 moves up to the maximum distance, thereby causing the support plate 3152 and the lifting leg 3153 to move up. After the drive component 23 is limited after the movement, the lifting leg 3153 is higher than the support leg, thereby making the front end of the detection box 1 in a raised state, which facilitates the subsequent observation of the display screen at the front end of the detection box 1. After use of the testing box 1, the operation is repeated to lift the testing box 1 and reset the drive component 23, so that the shielding component 22 continues to block the interface 11. As the drive component 23 contacts the pull plate 3156, it pushes the pull plate 3156 to move, causing the protrusion 314 and the lifting leg 3153 to return to their original positions, facilitating the subsequent stable placement of the testing box 1. The entire adjustment process is achieved through a multi-stage linkage mechanism. The movement of the drive component 23 first causes displacement of the drive frame 312, and then, through the sliding change of the protrusion 314 within the groove 313, precisely controls the lifting height of the support plate 3152 and the lifting leg 3153. This design allows the instrument to achieve multiple tilt positions at different angles, facilitating the connection operation of the interface 11 and optimizing the viewing angle of the display panel. The elastic rope 3155 provides continuous tension throughout the process, ensuring smooth movement and accurate reset of all components.

[0064] The system includes three connecting holes 121, each containing a metal bell 41. The alarm component 4 includes a striking block 42 slidably connected inside a slider 233. A second elastic element 43 is fixedly connected between the striking block 42 and the slider 233. The striking block 42 contacts the metal bell 41. The second elastic element 43 facilitates the extension and retraction of the alarm component 4, allowing it to move with the slider 233. When the slider 233 moves with the drive component 23, the striking block 42 contacts the metal bell 41 at different positions under the action of the second elastic element 43, producing a crisp striking sound. This sound cues accurately indicate the movement position of the drive component 23, providing clear positioning feedback to the operator. The sound signals generated by the collision between the striking block 42 and the metal bell 41 correspond to different working positions of the drive component 23, including the initial position, intermediate position, and maximum stroke position. With multiple audio signal feedbacks, the operator can know whether the drive component 23 has reached the predetermined position without visual confirmation, which greatly improves the efficiency and accuracy of operation.

[0065] The slider 233 has a through hole at the corresponding position of the striking block 42, and the striking block 42 is slidably connected in the through hole, which ensures that the movement trajectory of the striking block 42 is accurate and reliable, so that it can accurately strike the corresponding metal bell 41 and achieve a precise positioning prompt function.

[0066] In use, the movement of slider 233 synchronously drives alarm component 4 to slide on the inner wall of guide shell 12, while striking block 42 compresses second elastic component 43 to store energy during movement. The design of multiple connecting holes 121 provides precise positioning points for the movement of slider 233. When the lifting leg 3153 moves down to a specific distance, striking block 42 accurately enters the second connecting hole 121, striking the corresponding metal bell 41 and emitting a clear sound, indicating to the user that drive component 23 has reached the appropriate position and can be limited. This acoustic feedback ensures the accuracy of the plug insertion stage. As the operation continues, striking block 42 moves to the third connecting hole 121 and strikes the corresponding metal bell 41, emitting an audible signal again, indicating that drive component 23 has reached the maximum stroke position, reminding the user to perform the final limit. Real-time feedback of the operation process is achieved, effectively improving work efficiency and reducing the risk of misoperation. The entire alert system achieves positioning and sound generation through a precise mechanical structure. The movement of slider 233 drives the alarm element 4 to move synchronously. The sliding of the striking block 42 compresses the second elastic element 43 to store energy. When the striking block 42 reaches a specific position, the stored energy is released, pushing the striking block 42 to strike the metal bell 41 and produce a clear alert sound. This design ensures accurate sound feedback at different stages of operation, helping operators to grasp work progress and improve operational accuracy and work efficiency.

Effects and advantages of the invention: Describe the advantages of the invention compared with the prior art, in conjunction with its technical features: such as improved user experience, accuracy and efficiency, savings in time, processes, manpower and material resources; ease of operation and use, etc.

[0068] 1. Through the setting of the shielding component 2, the interface 11 is elastically covered by the shielding part 22 in cooperation with the coil spring. When not in use, the shielding part 22 shields the back interface 11 of the detection box 1, thereby preventing foreign objects from entering the interface 11 and avoiding subsequent poor contact or electrical short circuit, thus ensuring the stability of the equipment. Through the linkage design of the handle 24 and the drive rod 232, the operator can release the locking of the plug to the drive part 23 by pressing down with one hand, which facilitates the winding of the shielding part 22. By moving the handle 24 down, it is easy to limit the drive part 23 when it is moved to a suitable distance, which facilitates the subsequent adjustment of the tilt angle of the detection box 1.

[0069] 2. With the assistance of the auxiliary components, the lifting legs 3153 facilitate stable support of the testing box 1. With the assistance of the drive frame 312, the protrusion 314 moves with the protrusion 314. With the assistance of the groove 313, the extension block 3154 can be raised in sections. When the interface 11 is removed, the back of the testing box 1 can be raised, which facilitates the subsequent insertion of the connector. After the connector is inserted, as the drive frame 312 continues to move, the lifting legs 3153 can move upward, which makes it easier for the front of the testing box 1 to be raised. This allows the user to observe the display screen on the front of the testing box 1 and adjust its tilt angle multiple times according to the usage process of the testing box 1, increasing the convenience of the testing box 1. With the assistance of the elastic rope 3155, the drive frame 312 can be kept close to the drive component 23 to prevent accidental movement of the drive frame 312. With the assistance of the pull plate 3156, the drive frame 312 can be reset with the drive component 23, which facilitates the stable placement of the testing box 1.

[0070] 3. The reminder component, in conjunction with the connecting hole 121, facilitates the installation of multiple metal bells 41. The second elastic element 43 facilitates the extension and retraction of the alarm element 4, allowing the alarm element 4 to move with the slider 233. When the alarm element 4 strikes the metal bells 41, it produces a crisp sound, thereby positioning the drive element 23. This facilitates subsequent operation of the drive element 23 by the user and allows for adjustment of the tilt angle of the detection box 1, increasing work efficiency.
