[0062] See also Figure 2-Figure 4In this embodiment, the support hinge unit 7 includes an articulated mechanism 8 and an articulated roller shaft 9. The articulated mechanism 8 has two articulated mechanisms 8, which are symmetrically arranged and articulated on the articulated roller shaft 9, and one of the articulated mechanisms 8 is connected to the box cover 101, and the other articulated mechanism 8 is connected to the box body 102. The two articulated mechanisms 8 can rotate around the articulated roller shaft 9 as the box cover 101 and the box body 102 are opened and closed. With this design, when the staff opens the mobile test tool box 1 at the work site, the various test devices in the box are exposed, and the support hinge unit 7 is also exposed. The original articulated structure used to connect the box cover 101 and the box body 102 is designed to be the support hinge unit 7 in this application, which improves the rationality of space utilization and the convenience of actual operation.

[0063] See also Figure 4 In this embodiment, the hinge mechanism 8 includes a connecting rod body 10 and a supporting assembly 11;

[0064] One end of the connecting rod body 10 is set as an exposed part 1001, and the exposed part 1001 is hinged to the hinged roller shaft 9. The other end of the connecting rod body 10 is set as a hidden part 1002, and the hidden part 1002 is slidably plugged into the box cover 101 / box body 102. A flexible hoop 1003 is fixedly mounted on the connecting rod body 10 between the exposed part 1001 and the hidden part 1002. A plug-in slot is provided on the shell of the box cover 101 / box body 102. The hidden part 1002 is slidably matched with the plug-in slot. The flexible hoop 1003 can enter / exit the plug-in slot under a force-deformed state. An assembly slot 1004 is provided on the upward side of the hidden part 1002, and the support component 11 is installed in the assembly slot 1004.

[0065] With such design, the support hinge unit 7 has two working modes. One is that when the support component 11 is not needed, the mobile test tool box 1 can be opened normally. The other is that when the support component 11 is needed, after opening the mobile test tool box 1, the connecting rod body 10 is pulled forcefully to disengage the flexible hoop 1003 from the plug-in slot until the hidden portion 1002 is completely exposed. After use, the hidden portion 1002 is pushed forcefully along the plug-in slot until the flexible hoop 1003 is completely immersed in the plug-in slot. The structural design is reasonable and the operation is flexible and convenient, and it does not affect the normal testing and use of other equipment.

[0066] See also Figure 5-Figure 6 In this embodiment, the support assembly 11 includes a support connection module 12, a connection module 13 and a press self-locking module 14;

[0067] The push-to-lock module 14 is installed in the assembly groove 1004, and includes a push-to-lock seat 18 and a push-to-lock head 19. The push-to-lock seat 18 is fixed to the bottom surface of the inner wall of the assembly groove 1004. The push-to-lock head 19 is elastically installed in the push-to-lock seat 18 and has a movement stroke of popping out or resetting along the height direction of the push-to-lock seat 18 under a force state;

[0068] The connecting module 13 is vertically installed just above the push-to-lock module 14, and includes an articulated shaft cylinder 15, an articulated ball 16, and a connecting rod 17. One end of the connecting rod 17 is fixedly connected to the push-to-lock head 19, and the other end is fixedly connected to the articulated ball 16. The articulated ball 16 is embedded in the articulated shaft cylinder 15.

[0069] The supporting connection module 12 is vertically hingedly connected to the connection module 13. When the push-to-lock head 19 is in a force-popped-out state, it is completely exposed upward from the assembly groove 1004. When the push-to-lock head 19 is in a force-reset state, it is completely hidden downward inside the assembly groove 1004.

[0070] With this design, under the working condition that the support assembly 11 needs to be used, when the hidden part 1002 is completely pulled out, the connection module 13 is pressed, and the pressing self-locking head 19 is forced downward, driving the connection module 13 to pop up upward, so that the support connection module 12 is exposed outside the assembly groove 1004. Conversely, under the working condition that the support assembly 11 is not needed, the connection module 13 is pressed again, and the pressing self-locking head 19 is forced downward again, driving the connection module 13 to reset downward, so that the support connection module 12 is immersed in the assembly groove 1004, and does not affect the normal storage of the hidden part 1002.

[0071] After the supporting connection module 12 pops out of the assembly groove 1004, the hinge shaft 15 is moved around the hinge ball 16, so that the position of the supporting connection module 12 relative to the connecting rod 17 can be adjusted, that is, the angle position of the keyboard 20 can be adjusted, thereby improving the applicability to the working environment and the convenience of use for the staff.

[0072] It should be noted that the press-to-lock module 14 in the present application uses an elastic press-to-lock mechanism in the prior art, such as a ballpoint pen structure, an SD card structure, etc., which has the function of popping up or resetting under pressure, is easy to implement, and the specific structure and principle will not be repeated in this application.

[0073] See also Figure 7In this embodiment, the opening of the articulated shaft cylinder 15 faces downward, and a limiting barrel opening 1501 is provided at the barrel opening. The inner diameter of the limiting barrel opening 1501 is smaller than the diameter of the articulated ball 16, and two pitching slots 1502 are provided along the same diameter on the limiting barrel opening 1501, and the connecting rod 17 is engaged with the pitching slots 1502. With such a design, generally speaking, the most important thing that needs to be adjusted for the keyboard 20 under normal test and use is the support angle, that is, the pitch angle of the keyboard 20 itself. Therefore, by providing the pitching slot 1502 on the articulated shaft cylinder 15, rotating around the articulated ball 16, and engaging the pitching slot 1502 with the connecting rod 17, the pitching angle of the articulated shaft cylinder 15 and the supporting connection module 12 is adjusted, thereby achieving the adjustment of the pitching angle of the keyboard 20 mounted on the supporting connection module 12.

[0074] See also Figure 9-10 In this embodiment, the supporting connection module 12 includes a first hinged rod 21 and a second hinged rod 22 that are symmetrically distributed. The first hinged rod 21 and the second hinged rod 22 include a first rod body 2101 and a second rod body 2201 and a first magnetic strip 2102 and a second magnetic strip 2202 that are the same in shape and material;

[0075] The first magnetic strips 2102 have two strips, which are respectively fixed on the two sides of the inner side of the rod body along the length direction of the first rod body 2101, and a first cavity is formed between the two first magnetic strips 2102 on the inner side of the first rod body 2101;

[0076] The second magnetic strips 2202 have two strips, which are respectively fixed on the two sides of the inner side of the rod body along the length direction of the second rod body 2201, and a second cavity is formed between the two second magnetic strips 2202 on the inner side of the second rod body 2201;

[0077] The same end of the first rod body 2101 and the second rod body 2201 are both hinged around the circumference of the hinge shaft cylinder 15, and there is a movement range between the two to rotate around the hinge shaft cylinder 15 until they are adsorbed and merged or rotate away until the hinge rotation limit is reached.

[0078] With such a design, the first hinged rod 21 and the second hinged rod 22 are moved around the hinged shaft tube 15. During the separation process, the first magnetic strip 2102 and the second magnetic strip 2202 are separated first. When the separation reaches the hinge rotation limit, the first hinged rod 21 and the second hinged rod 22 form a right-angled triangle under the hinged action of the hinged shaft tube 15, which are used to stably support the four corners of the keyboard 20.

[0079] See also Figure 11-13 In this embodiment, an embedding groove 2103 is centrally formed on the inner side of the first rod body 2101, a telescopic support member 23 is hinged in the embedding groove 2103, and sliding rods 24 are symmetrically fixed on both sides of the inner side of the first rod body 2101, and the sliding rods 24 extend outward into the first cavity;

[0080] A limit slot 2203 is provided on the inner side of the second rod body 2201 near the bottom, and springs 25 are symmetrically distributed on both sides of the limit slot 2203 on the inner side of the second rod body 2201. The spring 25 is placed outwardly in the second cavity, and one end of the spring 25 is fixed to the inner side of the second rod body 2201 near the bottom, and the other end is slidably sleeved on the slide bar 24.

[0081] When the first rod body 2101 and the second rod body 2201 are adsorbed and merged with each other, the telescopic support member 23 is embedded in the embedding groove 2103, and the sliding end of the spring 25 slides to the bottom end of the slide bar 24. When the first rod body 2101 and the second rod body 2201 are rotated away from each other around the hinge shaft tube 15, the sliding end of the spring 25 slides along the slide bar 24 toward the top end of the rod body. When the first rod body 2101 and the second rod body 2201 are rotated away from each other until the hinge rotation limit is reached, the sliding end of the spring 25 slides to the top end of the slide bar 24, and the telescopic support member 23 contacts the limit slot 2203.

[0082] With this design, since the magnetic strip protrudes outward from the rod body, a cavity for accommodating the slide bar 24 and the spring 25 can be formed. During the process of the first rod body 2101 and the second rod body 2201 rotating and separating, the sliding end of the spring 25 gradually slides from the bottom of the slide bar 24 to the top thereof until the hinge rotation limit state is reached, and the telescopic support member 23 is taken out, with one end hinged to the first rod body 2101 and the other end supporting and contacting the second rod body 2201. Thus, the support connection module 12 forms a triangular shape with a stable structure, which can provide stable support for the keyboard 20.

[0083] Conversely, in the process of the first rod body 2101 and the second rod body 2201 rotating closer to each other, the telescopic support member 23 is first stored in the embedding groove 2103, and then the sliding end of the spring 25 gradually slides from the top of the slide rod 24 to the bottom thereof, until the first magnetic strip 2102 and the second magnetic strip 2202 are adsorbed and fixed to each other, thereby completing the storage of the support connection module 12.

[0084] See also Fig.14In this embodiment, the telescopic support member 23 includes a telescopic connecting rod 26, a limit head 27 and a hinge shaft 28;

[0085] The hinge shaft 28 is fixedly provided at the bottom of the telescopic connecting rod 26 and is hingedly matched with the embedding groove 2103. The telescopic connecting rod 26 includes an outer rod body 2601 and an inner rod body 2602. The outer rod body 2601 has two, which are spaced apart, and the bottoms of the two outer rod bodies 2601 are fixed via a cross bar. The inner rod body 2602 has two, which are slidably inserted into the outer rod body 2601 respectively, and the inner rod body 2602 is matched with the positioning groove provided on the inner wall of the top of the outer rod body 2601 via the elastic telescopic positioning block installed at the bottom. The limit head 27 is horizontally fixed at the top of the two inner rod bodies 2602, and the limit head 27 is matched with the limit card slot 2203.

[0086] The four bottom corners of the keyboard 20 are respectively hinged with leaf pieces 2001 , and the leaf pieces 2001 can pass through the middle gap of the telescopic connecting rod 26 and be obliquely inserted on the telescopic supporting member 23 .

[0087] With this design, the page 2001 is moved and inserted along the gap between the two outer rods 2601 or the two inner rods 2602, so that the four corners of the keyboard 20 are respectively mounted on the supporting components 11, and then the articulated shaft cylinder 15 is moved to adjust the pitch angle according to the actual use conditions and working environment to complete the adjustment of the mounting angle of the keyboard 20. After use, the keyboard 20 is directly removed and the page 2001 is reset, and then put back to the original position in the box 102. It is simple and easy to operate.

[0088] In summary, in the present invention, on the one hand, the environmental data monitoring unit, the data communication transmission unit, the online performance calculation unit, the report generation unit and the power supply unit are integrated and installed in the mobile test tool box, and the environmental data of the current working environment of the gas turbine and steam turbine combined cycle unit and the real-time operating parameters of the gas turbine and steam turbine combined cycle unit are collected and acquired, and the performance parameters of the gas turbine and steam turbine combined cycle unit are calculated, analyzed and corrected online, and the performance report is generated and sent to the client end through online summary processing, so as to realize remote real-time grasp of the performance status of the unit, system and thermal equipment, so as to adjust the operation mode of the equipment in time, and the control timeliness is strong;

[0089] On the other hand, the original hinged structure for connecting the lid and the body of the mobile test tool box is improved, and a supporting hinge unit including a supporting assembly is added on the basis of the original hinged structure, which neither affects the normal opening and closing hinges of the mobile test tool box nor the normal testing and use of the equipment in the box. At the same time, the keyboard is supported and the support angle is adjusted through foldable extension / folding closure / pitch adjustment, which improves the convenience of use for staff and the applicability to the test environment, and has strong operational flexibility.
