[0049] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0050] Example 1

[0051] This embodiment provides an oil and gas test platform system, which has a container structure and integrates relevant facility systems, and has the characteristic of mobility; the intelligent construction of the integrated facility system can facilitate user operation.

[0052] See Figure 1-3 The container-type intelligent oil and gas testing platform system provided in this embodiment can include a box-type main body 1, and an operating space 2 is formed inside the box-type main body 1; a door and window system is arranged at the box-type main body 1, and a testing system is arranged inside the operating space 2; the testing system includes a testing bench 3 arranged inside the operating space 2, and a testing station is arranged at the testing bench 3, and the corresponding testing instrument is detachably arranged at the testing station through a testing instrument protection base.

[0053] The oil and gas testing platform system of this embodiment, by adopting a container-type structure and building a testing system, can meet the needs of mobile oil and gas testing and achieve the purpose of testing oil samples at the site where the oil samples are located; thereby, the time consumption of oil and gas testing can be greatly reduced, which is beneficial to speeding up the progress of the project, and can especially meet the testing and detection needs in work scenarios such as emergency repairs.

[0054] Among them, the box-type body 1 can be directly modified from an existing container, so the main structure is easy to manufacture. For example, door openings and window openings can be directly opened in the existing container, and the door body 4 and the window body 5 can be installed at the door openings and window openings to achieve the integration of the door and window system. By laying decorative panels and other components inside the box-type body 1, the operation space 2 can be preferably formed, and the existing related equipment can be directly integrated with the box-type body 1 and / or the operation space 2 to achieve the integrated manufacturing of the entire oil and gas test platform system.

[0055] The design of the test instrument protection base enables different test instruments to be installed at the test station as needed. This modular design can meet the needs of installing different test instruments in different testing scenarios, which is especially beneficial for operation in emergency repair work scenarios.

[0056] The test instruments may include existing test instruments that can be used to carry out physical and chemical properties, insulation properties, chromatographic analysis, etc. of insulating oil, such as the instruments listed in the following table.

[0057]

[0058] The box-type main body 1 and / or the operating space 2 of this embodiment can integrate a power supply system and an auxiliary system, and the power supply system is used to power the auxiliary system and the test instruments. The design of the power supply system can solve the power supply problem of the oil and gas test platform system, and the design of the auxiliary system can enrich the other functions of the oil and gas test platform system.

[0059] The door and window system includes a door body 4 and a window body 5 provided at the box-type main body 1. In this embodiment, the specific parameters of the door body 4 and the window body 5 are not limited, and those skilled in the art can purchase existing doors and windows for integrated installation as needed.

[0060] Among them, an air shower room 3 can be arranged at the door body 4 in the operation space 2. As a conventional building component, the air shower room 3 is essentially a channel design, one end of the channel can be located at the door body 4, and the other end of the channel can be connected to the operation space 2 through the air shower room door. Similarly, the specific parameters of the air shower room 3 are not limited in this embodiment, and those skilled in the art can purchase or design an existing air shower room for integrated installation as needed.

[0061] See Figure 4 The auxiliary system can include a control system, an access control system at the door body 4, an air shower dust removal system at the air shower room 3, a lighting system in the box body 1, an environmental monitoring system at the operating space 2, a fresh air system, an air conditioning system and other subsystems. Among them, the power supply system can transmit power to each subsystem and each test station through the busbar, and the power supply end of the power supply system can form a power supply interface, which can be connected to the power grid or the existing power storage system.

[0062] Specifically,

[0063] The control system can include a gateway unit, through which data interaction with various subsystems can be achieved;

[0064] The access control system can include an intelligent door lock disposed at the door body 4, and the intelligent door lock can adopt an existing electronic lock with functions such as fingerprint recognition and face recognition;

[0065] The air shower dust removal system is a component integrated in the air shower room 3, which is an existing mature technology; it can be understood that the air shower dust removal system can include a fan;

[0066] The lighting system can include a lamp and a controller for the lamp;

[0067] After the control system forms data interaction with the controllers of the smart door lock, the fan and the lamp through the gateway unit, it can read the opening and closing actions of the smart door lock, and then control the actions of the fan and the lamp based on the opening and closing of the smart door lock; and then the control system can control the operation of the power supply system, and control the operation of the air shower and dust removal system and the lighting system when it detects that the access control system is in the open state; for example, a remote control switch can be set in series at the bus of the power supply system and connected to the control system through the gateway unit. When the control system reads that the door opening action occurs at the access control system and the bus is in the disconnected state, the remote control switch action can be controlled to realize the passage at the bus, and then relevant instructions can be sent to the air shower and dust removal system and the lighting system at the same time to control the fan to run for a set time and control the lighting system to be in a working state; further, in the above example, when the control system reads that the door opening action occurs at the access control system and the bus is in the passage state, it can only control the fan to run for a set time; in addition, in the above example, the control system can only control the remote control switch to put the bus in the passage state, and manual operation is required to control the remote control switch to put the bus in the disconnected state;

[0068] Of course, the lighting system can also adopt an inductive design to achieve self-sensing operation;

[0069] The control system can also have, for example, a voice-based artificial interaction system, thereby enabling voice-based control of each subsystem;

[0070] The environmental monitoring system can have sensor units such as temperature sensors and harmful gas sensors, and the environmental monitoring system can be connected to the control system through a gateway unit, thereby sending the detected environmental data to the control system;

[0071] The fresh air system and the air-conditioning system can adopt conventional fresh air devices and air-conditioning devices. By setting relevant thresholds at the environmental monitoring system, the control system can control the fresh air system or the air-conditioning system to perform corresponding actions when the real-time environmental parameters in the operating space 2 detected by the environmental monitoring system reach the preset thresholds.

[0072] The auxiliary system in this embodiment can be implemented based on the current smart home system, for example. The solution of this implementation mainly proposes an oil and gas test platform system based on a container and integrating a test system and an auxiliary system.

[0073] In addition, the test system in this embodiment further includes a sample dispensing device disposed in the operating space 2, so that the oil sample can be distributed quickly and efficiently.

[0074] Example 2

[0075] In addition, considering that during the oil and gas test, the sample needs to be distributed into the required amount; for example, when extracting samples, a large sampling bottle will be used to extract about 550ml of oil sample, of which 400ml is used for insulating oil withstand voltage test, 50ml is used for insulating oil water-soluble acid test, 20ml is used for insulating oil dielectric loss and resistivity test, 20ml is used for insulating oil acid value test, 15ml is used for insulating oil tension test, 5ml is used for insulating oil flash point test, and 10ml is used for insulating oil micro-water test. In this process, the reasonable distribution of oil samples is more important, and accurate and efficient distribution of samples directly affects the efficiency and accuracy of oil and gas testing.

[0076] like Figure 5-16 As shown, the present embodiment provides a sample distribution device that can be used in Example 1, including a device body 100, the device body 100 includes a shell 110; the shell 110 includes a bottom plate 150, and a mounting seat 120 is provided at the bottom plate 150; a mounting cavity is provided in the mounting seat 120, and a holding mechanism 460 for placing multiple test tubes is provided in the mounting cavity; an extraction mechanism 300 is also provided in the mounting cavity, and the extraction mechanism 300 is used to cooperate with the holding mechanism 460 to extract the oil samples in the sampling bottle 160 into the test tubes respectively.

[0077] Through this embodiment, after the staff takes the oil sample back to the laboratory, the staff places the sampling bottle 160 on the bottom plate 150, then inserts one end of the hose 180 into the sampling bottle 160, and then covers the sealing cover on the sampling bottle 160. Then the staff pulls the handle 190 on the push plate 220 to pull the push plate 220 out of the second sub-mounting cavity 940. Then the staff inserts the test tube into the first through hole 801 and the blind hole 890 on the support frame respectively, and then pushes the push plate 220 into the second sub-mounting cavity 940; then the extraction mechanism 300 and the holding mechanism 460 are started through the operation screen 130 on the shell 110; the sample in the sampling bottle 160 is extracted by the pump 410 in the extraction mechanism 300, and sprayed into the holding mechanism from the injection head 450. The first mounting plate 850 is driven to rotate by the first motor 840 to allow multiple test tubes on the support frame to pass under the injection head 450 in turn, and the amount of sample liquid entering different test tubes is controlled by the electromagnetic flow valve 560 at the injection head 450. After the sample liquid is injected, the push plate 220 is pulled out again to bring the support frame out of the second sub-mounting cavity 940. At this time, the staff removes the test tube injected with the sample liquid on the support frame and performs different tests accordingly. Compared with the prior art, the device does not require manual injection of sample liquid into the test tube, and can also inject multiple test tubes at the same time, thereby preferably saving the time of the staff to extract the sample liquid, saving the time used for the test, and improving the test efficiency.

[0078] In this embodiment, a partition 930 is provided in the installation cavity, and the partition 930 divides the installation cavity into a first sub-installation cavity 910 and a second sub-installation cavity 940; the containing mechanism 460 includes a first installation plate 850 arranged in the second sub-installation cavity 940, and a support frame is provided above the first installation plate 850; the support frame includes an upper cover plate 810 and a lower cover plate 830, and a plurality of support plates 820 are provided between the upper cover plate 810 and the lower cover plate 830; a plurality of first through holes 801 arranged along the center of the upper cover plate 810 are provided at the upper cover plate 810; a blind hole 890 arranged corresponding to the first through hole 801 is provided at the lower cover plate 830; a first installation groove 880 is provided at the end surface of the first installation plate 850 close to the lower cover plate 830, and a first motor 840 for driving the lower cover plate 830 to rotate is provided in the first installation groove 880.

[0079] Through this embodiment, the staff passes the test tube through the first through hole 801 on the upper cover 810, so that the bottom of the test tube extends into the blind hole 890 on the lower cover 830, thereby fixing the test tube to prevent the test tube from shaking when the first motor 840 drives the lower cover 830 to rotate, thereby causing the test tube to tilt and fail to align with the injection head 450.

[0080] In this embodiment, an opening 210 communicating with the second sub-mounting cavity 940 is provided at the side wall of the mounting seat 120; a push plate 220 is provided at the opening 210 and extends into the second sub-mounting cavity 940 through the opening 210; the push plate 220 includes a horizontal plate 1002 extending into the second sub-mounting cavity 940, and a vertical plate 1001 for blocking the opening 210; a second mounting groove 990 arranged along the length direction of the horizontal plate 1002 is provided at the horizontal plate 1002; a sliding block 860 extending into the second mounting groove 990 is provided at the lower end of the first mounting plate 850, and a threaded through hole 870 is provided at the sliding block 860; a threaded rod 901 passing through the threaded through hole 870 is provided in the second mounting groove 990, and a second motor 980 for driving the threaded rod 901 to rotate is also provided in the second mounting groove 990; two containing mechanisms 460 are provided.

[0081] Through this embodiment, when the staff conducts more tests and needs to use more sample liquid, the staff can put test tubes on the support frames of the two containing mechanisms 460, and then drive the threaded rod 901 to rotate through the second motor 980, driving the sliding block 860 to slide along the second mounting groove 990, so that the two support frames are moved to the bottom of the injection head 450 in turn, and then drive the lower cover plate 830 to rotate through the first motor 840, thereby driving the test tubes to pass under the injection head 450 in turn; so that the staff can store test tubes corresponding to the number of test sites in the device for liquid injection according to the number of test sites, thereby saving time for injecting liquid into the test tubes.

[0082] In this embodiment, guide grooves 970 arranged along the width direction of the mounting seat 120 are provided on the side walls at both ends of the second sub-mounting cavity 940 ; guide blocks 1003 extending into the guide grooves 970 are provided on the side walls at both ends of the cross plate 1002 .

[0083] Through this embodiment, when the staff pulls the push plate 220, the guide block 1003 at the horizontal plate 1002 moves along the guide groove 970, thereby better improving the stability of the horizontal plate 1002 when moving.

[0084] In this embodiment, the extraction mechanism 300 includes a mounting frame 320 arranged in the first sub-mounting cavity 910, and the mounting frame 320 includes a second mounting plate 430, and the lower end of the second mounting plate 430 is provided with a support foot 440 connected to the partition 930; a telescopic tube 420 is provided in the first sub-mounting cavity 910 and passes through the second mounting plate 430, and the lower end of the telescopic tube 420 is provided with a hollow injection head 450 that passes through the partition 930 and extends into the second sub-mounting cavity 940; a hose 180 is provided at the upper end of the telescopic tube 420, and the hose 180 passes through the side wall of the mounting seat 120 and extends into the sampling bottle 160, and a sealing cover 170 for sealing the opening of the sampling bottle 160 is provided at one end of the hose 180 close to the sampling bottle 160; a pump 410 is provided at one end of the telescopic tube 420 close to the hose 180, and an electromagnetic flow valve 560 is provided at the side wall of the telescopic tube 420.

[0085] Through this embodiment, the staff starts the pump 410 through the controller, and the pump 410 draws the sample liquid in the sampling bottle 160 into the hose 180. The sample liquid enters the telescopic tube 420 and the injection head 450 through the hose 180. The amount of sample liquid entering the injection head 450 is controlled by the electromagnetic flow valve 560, so as to facilitate the control of the amount of sample liquid entering different test tubes; the sealing cover 170 is fixed to the mouth of the sampling bottle 160, so as to facilitate the fixing of the hose 180 and prevent the hose 180 from tilting and failing to extend to the bottom of the sampling bottle 160.

[0086] In this embodiment, both sides of the telescopic tube 420 are provided with a cylinder 330 arranged on the second mounting plate 430, and the push rod of the cylinder 330 passes through the second mounting plate 430. The end of the cylinder 330 passing through the second mounting plate 430 is provided with a connecting plate 520 for connecting the two push rods of the cylinder 330, and the connecting plate 520 is provided with a second through hole 720 for the telescopic tube 420 to pass through; the injection head 450 is provided with a third mounting plate 550 near one end of the telescopic tube 420; the telescopic tube 420 passes through the third mounting plate 550 and extends into the injection head 450, and the telescopic tube 420 extends into the injection head 450. A flange 1101 is provided at one end; a first mounting ring 920 is provided at the inner wall of the injection head 450, and a first spring 960 is provided between the first mounting ring 920 and the flange 1101; guide columns 540 located on both sides of the telescopic tube 420 are provided between the third mounting plate 550 and the connecting plate 520; a third through hole 710 for the guide column 540 to pass through is provided at the connecting plate 520; a second spring 530 is provided between the third mounting plate 550 and the connecting plate 520 and is sleeved on the guide column 540; a second mounting ring 570 is provided on the side wall of the telescopic tube 420 located at the lower end of the connecting plate 520.

[0087] According to this embodiment, after the sample liquid is injected into the test tube through the injection head 450, the controller controls the cylinder 330 to start, and the push rod of the cylinder 330 pushes the connecting plate 520 to move downward, and the connecting plate 520 moves downward to push the second spring 530, so that the second spring 530 pushes the third mounting plate 550 and the injection head 450 to move downward, so that the injection head 450 extends into the test tube. After the injection head 450 extends into the test tube, the third mounting plate 550 abuts against the second mounting plate 430. At this time, the cylinder 330 continues to push the connecting plate 520 downward, so that the connecting plate 520 pushes the second mounting ring 570 downward, and at the same time, the connecting plate 5 20 squeezes the second spring 530, and the second mounting ring 570 moves downward to drive the telescopic tube 420 to move downward, so that the telescopic tube 420 goes deeper into the injection head 450, thereby pushing the residual liquid in the injection head 450 into the test tube, thereby preventing the residual liquid in the injection head 450 from causing insufficient sample liquid in the test tube and inaccurate test data; when the liquid in the injection head 450 is pushed out, the push rod of the cylinder 330 pulls the connecting plate 520 upward, and the telescopic tube 420 moves upward when the first spring 960 pushes the flange 1101 until the second mounting ring 570 on the telescopic tube 420 is against the bottom of the connecting plate 520.

[0088] In this embodiment, a baffle 510 is disposed at one end of the guide post 540 passing through the third through hole 710 .

[0089] According to this embodiment, the blocking plate 510 blocks the guide post 540 from being separated from the third through hole 710 , thereby preventing the guide post 540 from being separated from the connecting plate 520 during the movement of the connecting plate 520 .

[0090] In this embodiment, an annular groove 1102 is provided on the outer side wall of the flange 1101 , and a rubber ring 1103 is provided in the annular groove 1102 .

[0091] Through this embodiment, the rubber ring 1103 on the flange 1101 is against the inner wall of the injection head 450, thereby preventing a gap from existing between the flange 1101 and the inner wall of the injection head 450, resulting in liquid leaking out of the gap when the flange 1101 moves downward, causing a reduction in the amount of liquid entering the test tube and affecting the test data.

[0092] In this embodiment, a limiting groove 310 is provided on the bottom plate 150 for the bottom of the sampling bottle 160 to extend into.

[0093] Through this embodiment, the staff puts the sampling bottle 160 on the limiting groove 310 on the bottom plate 150 , and the limiting groove 310 limits the sampling bottle 160 to prevent the sampling bottle 160 from moving and separating from the bottom plate 150 .

[0094] This embodiment provides a transformer oil sample extraction system, including a transformer oil sample extraction device.

[0095] Through this embodiment, the system eliminates the need for staff to manually inject sample liquid into test tubes, and can also inject into multiple test tubes, thereby effectively saving staff time in extracting sample liquid, saving test time, and improving test efficiency.

[0096] Example 3

[0097] In addition, considering the need for mobility of the oil and gas test platform system in Example 1, in order to protect the test instruments during transportation, this embodiment provides a specific implementation method of a test instrument protection base.

[0098] See Figure 17-24 The test instrument protection base provided in this embodiment includes a plurality of support legs 100, which together constitute a protection base for installing the test instrument, and the support legs 100 include a shock absorbing assembly 110 for being arranged at an oil and gas test platform;

[0099] The shock absorbing assembly 110 has two mounting plates 210 symmetrically arranged up and down, a supporting assembly 220 and two steel wire rope shock absorbers 230 symmetrically arranged along the supporting assembly 220 are arranged between the two mounting plates 210, the supporting assembly 220 is used to connect the two mounting plates 210, and the steel wire rope shock absorbers 230 are used to provide elastic force to keep the two mounting plates 210 facing each other;

[0100] The support assembly 220 includes a first support arm 330 and a second support arm 340 that are cross-hinged. There is a cross axis between the first support arm 330 and the second support arm 340. A locking assembly 240 is slidably provided between the cross axes. The locking assembly 240 is used to lock the cross angle of the first support arm 330 and the second support arm 340.

[0101] When the present invention is used, a plurality of supporting legs 100 are arranged according to the size of the protective base required for the installation of the test instrument, and then the test instrument is installed on the protective base for fixing. When transporting, the locking assembly 240 is pulled away from the intersection axis between the first supporting arm 330 and the second supporting arm 340, so that the locking assembly 240 releases the limitation of the first supporting arm 330 and the second supporting arm 340;

[0102] When a complex and high-precision oil and gas test is performed on the test instrument, the locking assembly 240 is inserted into the cross axis between the first support arm 330 and the second support arm 340, so that the locking assembly 240 can lock the first support arm 330 and the second support arm 340. Compared with the prior art, the user can adjust the shock-absorbing state or the fixed state of the support foot 100 according to different application scenarios, thereby avoiding the problem that the existing protective base cannot be fixed when performing complex and high-precision oil and gas tests, resulting in shaking of the instrument during the test, causing the test instrument or the oil and gas to be tested to deviate, and affecting the detection accuracy.

[0103] In fact, when installing test instruments of different weights, the test instruments of different weights exert different pressures on the protective base formed by the support legs 100. This device can adapt to different weights and limit the protective base formed by the support legs 100 after pressing down, which greatly improves the application range of the device.

[0104] Example 4

[0105] This embodiment also provides a test instrument protection base, which differs from Embodiment 3 in that: a mounting seat 250 is provided at the middle of the opposite sides of the mounting plate 210, two slide grooves 310 are provided at the top of the mounting seat 250, and the support assembly 220 also includes a slider 320 hinged at both ends of the first support arm 330 and the second support arm 340, and the sliders 320 are respectively slidably arranged in the slide grooves 310.

[0106] Through the above structure, the mounting seat 250 is arranged in the middle of the opposite side of the mounting plate 210, providing a stable support point for the support assembly 220, and through the cooperation of the slide groove 310 and the slider 320, the first support arm 330 and the second support arm 340 can be firmly connected between the two mounting plates 210 to form a stable support structure.

[0107] In this embodiment, the cross shafts are connected with a plug-in cavity 410, a spline groove 420 is formed in the plug-in cavity 410, and an extension column 430 is provided on the side wall of the second support arm 340 away from the first support arm 330. A cavity that penetrates the plug-in cavity 410 is formed inside the extension column 430, and the locking assembly 240 is slidably disposed in the cavity;

[0108] The locking assembly 240 has a first slide plate 440 that is slidably arranged in the cavity. A plug-in column 450 is provided on the corresponding side of the first slide plate 440 and the plug-in cavity 410. A spline that matches the spline groove 420 is provided on the outer wall of the plug-in column 450. The first slide plate 440 movably passes through the extension column 430 and is fixed with a handle 460 at one end.

[0109] The plug-in column 450 is always located in the plug-in cavity 410 at the second support arm 340 .

[0110] Specifically, when it is necessary to limit the position of the first support arm 330 and the second support arm 340, the plug-in column 450 is simultaneously inserted into the plug-in cavity 410 in the first support arm 330 and the second support arm 340, and the first support arm 330 and the second support arm 340 can be limited by the engagement of the spline at the plug-in column 450 with the spline groove 420.

[0111] Through the above structure, the plug-in cavity 410 and the spline groove 420 in the cross shaft cooperate with the plug-in column 450 in the locking assembly 240 and the splines thereon, so as to accurately lock the crossing angle between the first support arm 330 and the second support arm 340 under the test instrument bearing different weights, and ensure that the support assembly 220 can maintain a horizontal and stable shape when bearing loads. At the same time, the user can control the locking and unlocking of the plug-in column 450 in the spline groove 420 by operating the handle 460, so that the locking process of the support assembly 220 of the test instrument bearing different weights becomes simple and quick.

[0112] In this embodiment, a first magnetic sheet 470 is fixedly provided on one side of the first slide plate 440 close to the handle 460 , and a second magnetic sheet 480 adsorbed to the first magnetic sheet 470 is fixedly provided on the side wall corresponding to the cavity and the first magnetic sheet 470 .

[0113] Through the above structure, when the first support arm 330 and the second support arm 340 are not limited, the plug-in column 450 is always located away from the plug-in cavity 410 at the first support arm 330, thereby reducing the situation where the plug-in column 450 enters the plug-in cavity 410 at the first support arm 330 and causes limitation due to vibration or impact.

[0114] In this embodiment, the two mounting plates 210 also have mounting grooves 510 for sliding installation of the wire rope shock absorber 230 on the opposite sides. The wire rope shock absorber 230 includes two fixing seats 610 symmetrically arranged up and down and a wire rope 620 installed between the two fixing seats 610. The two wire rope shock absorbers 230 are respectively fixed with a first plug-in block 630 and a second plug-in block 640 at the opposite ends thereof. The first plug-in block 630 and the second plug-in block 640 are equidistantly provided with a plurality of concave portions 650 arranged in a semicircle on the opposite sides thereof. The concave portions 650 at the opposite sides of the first plug-in block 630 and the second plug-in block 640 jointly form a plug-in hole.

[0115] A through groove 520 is formed at the bottom of the mounting seat 250 for the first plug-in block 630 and the second plug-in block 640 to pass through. A vertically arranged mounting cavity is provided at the mounting seat 250. A positioning assembly 260 is provided in the mounting cavity. The positioning assembly 260 is used to cooperate with the plug-in hole to limit the two wire rope shock absorbers 230.

[0116] Through the above structure, the mounting groove 510 on the mounting plate 210 allows the wire rope shock absorber 230 to be slidably installed, so that the wire rope shock absorber 230 can be adjusted in position according to actual needs to adapt to different installation environments and shock absorption requirements, which greatly improves the adaptability and practicality of the equipment. At the same time, the user can adjust the vertical inclination of the wire rope 620 at the two fixing seats 610 according to needs. When the wire rope 620 is used for a long time, the toughness of the wire rope 620 will be weakened. The user can adjust the inclination angle of the wire rope 620 at the two fixing seats 610 appropriately to improve the toughness of the wire rope 620.

[0117] Specifically, the coordinated arrangement of the first plug-in block 630 and the second plug-in block 640, and the plug-in hole formed therebetween, cooperate with the positioning assembly 260 in the mounting base 250 to achieve a stable connection and limitation of the wire rope shock absorber 230, which not only ensures the stability of the wire rope shock absorber 230 during operation, but also prevents loosening or falling off due to vibration or impact. At the same time, there is no need to reconnect with bolts, and different wire rope shock absorbers 230 can be quickly installed and adjusted.

[0118] In fact, the cross-hinged first support arm 330 and the second support arm 340 occupy the smallest space between the two mounting plates 210, and also provide a larger shock-absorbing compression space for the wire rope shock absorber 230.

[0119] In this embodiment, the positioning assembly 260 has a second slide plate 530 slidably arranged in the installation cavity, a pin 540 cooperating with the plug hole is fixedly arranged at the bottom wall of the second slide plate 530, a pull ring is fixedly arranged at one end of the second slide plate 530 that moves through the installation cavity, and a first spring 550 is fixedly arranged between the top wall of the installation cavity and the second slide plate 530, and the first spring 550 is used to provide an elastic force to keep the second slide plate 530 pressed downward.

[0120] Through the above structure, a pull ring is fixedly provided at one end of the second slide plate 530 that is movable through the installation cavity, so that the user can easily control the up and down movement of the second slide plate 530 by pulling the pull ring. When the wire rope shock absorber 230 needs to be installed or removed, the user only needs to pull the pull ring to withdraw the pin 540 from the plug-in hole to easily complete the operation, which greatly simplifies the installation and maintenance process and improves the installation efficiency.

[0121] A first spring 550 is fixed between the top wall of the mounting cavity and the second slide plate 530. The spring provides a downward pressing elastic force for the second slide plate 530, so that when there is no external force, such as when the pull ring is not pulled, the pin 540 will automatically remain in the plug hole, ensuring the stability of the connection. At the same time, it also helps to maintain the stability of the connection under vibration or impact conditions.

[0122] In this embodiment, a first plugging slot 660 for plugging in the second plugging block 640 is provided at a position corresponding to one of the fixing seats 610 and the second plugging block 640 , and a second plugging slot 670 for plugging in the first plugging block 630 is provided at a position corresponding to the other fixing seat 610 and the first plugging block 630 .

[0123] Through the above structure, the second plug-in block 640 and the first plug-in block 630 can be quickly positioned, and the space occupied by the second plug-in block 640 and the first plug-in block 630 can be saved.

[0124] Example 5

[0125] This embodiment also provides a test instrument protection base, which differs from Embodiment 4 in that a connecting cavity is provided on the side wall of the mounting seat 250 and is vertically penetrated through the mounting cavity. A locking assembly 270 is provided in the connecting cavity, and the locking assembly 270 is used to lock the positioning assembly 260.

[0126] Through the above structure, the introduction of the locking assembly 270 provides an additional locking function for the positioning assembly 260. When the positioning assembly 260, especially the second slide 530, is in the correct position, the locking assembly 270 can lock it to prevent it from accidentally moving under vibration or impact. The double locking mechanism including the cooperation of the pin 540 and the plug-in hole and the locking of the locking assembly 270 ensures that the connection between the wire rope shock absorber 230 and the mounting base 250 is more stable and reliable.

[0127] In this embodiment, the locking assembly 270 has a third slide plate 710 slidably arranged in the connecting cavity, and a locking column 720 is provided at the corresponding position of the third slide plate 710 and the latch 540. The locking column 720 movably passes through the connecting cavity and is fixed with a pulling ring 730 at one end. A second spring 740 is fixed between the third slide plate 710 and the inner wall of the connecting cavity. The second spring 740 is used to provide an elastic force to keep the third slide plate 710 pressed toward the direction of the latch 540.

[0128] Through the above structure, the pulling ring 730 on the third slide plate 710 provides a convenient operation method for the user. The user pulls the pulling ring 730 to overcome the elastic force of the second spring 740, so that the card column 720 is disengaged from the pin 540, thereby unlocking the positioning assembly 260. The unlocking and locking process is simple, reliable and fast.

[0129] In this embodiment, a guide groove 750 for the sliding of the card column 720 is provided on the opposite side of the latch 540 and the card column 720 , and a positioning hole 760 for the card column 720 to be inserted is provided on the bottom side wall of the guide groove 750 .

[0130] Through the above structure, the guide groove 750 set on the pin 540 provides a precise sliding path for the card column 720. When the third slide plate 710 drives the card column 720 to move toward the pin 540, the card column 720 will slide along the guide groove 750 until it reaches a predetermined position, ensuring that the card column 720 can accurately cooperate with the pin 540 and avoiding locking failure due to position deviation. When the card column 720 slides to the bottom along the guide groove 750, it will be inserted into the positioning hole 760, thereby achieving a stable locking with the pin 540. This locking method is not only simple and reliable, but also can effectively prevent loosening due to vibration or impact.
