DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a portable FTU detection device, which includes a box 100 and a detection unit 200.

[0035] The detection unit 200 includes a mounting shaft 201 disposed in the box 100, a winding roller 202 disposed on the mounting shaft 201, a coil spring 203 disposed between the mounting shaft 201 and the winding roller 202, and an aviation soft wire 204 disposed on the winding roller 202;

[0036] The aviation cord 204 is wound around the winding roller 202 in an initial state. When the aviation cord 204 is needed, it can be pulled out from the winding roller 202 by simply pulling the aviation cord 204. When the aviation cord 204 is pulled out, the coil spring 203 is compressed. When the aviation cord 204 is released, the coil spring 203 pops out and can drive the winding roller 202 to rotate, thereby automatically winding the aviation cord 204.

[0037] During use, when conducting a test, first climb up and pull the aviation cord 204 to the ground, and then plug in the detection device for detection. The aviation cord 204 will compress the coil spring 203 when pulled. When the test is completed, release the aviation cord 204. Under the elastic force of the coil spring 203, the aviation cord 204 can be automatically retracted, which is convenient for pulling out for detection next time.

[0038] Example 2, reference Figure 2 and 3 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that it also includes a locking unit 300, which includes a fixing box 301 arranged on the inner wall of the box body 100, an airbag 302 arranged on the fixing box 301, and an air injection component 303 arranged on the fixing box 301. The fixing box 301 is injected with air through the air injection component 303, so that the airbag 302 expands. When the airbag 302 expands, it will resist the winding roller 202, preventing the winding roller 202 from rotating under the elastic force of the coil spring 203.

[0039] Among them, the winding roller 202 includes a support ring 202a rotatably connected to the installation shaft 201, a winding ring 202b arranged on the support ring 202a, and a locking ring 202c arranged at the other end of the winding ring 202b; the inner side of the winding ring 202b is connected to the coil spring 203, and the outer side thereof is connected to the aviation soft wire 204; the locking ring 202c cooperates with the airbag 302, and the airbag 302 will resist the locking ring 202c after expansion, thereby increasing the friction between the two, so that after the aviation soft wire 204 is pulled out, the rotation of the locking ring 202c is limited to ensure that the aviation soft wire 204 will not be retracted.

[0040] Further, the gas injection assembly 303 includes an air inlet pipe 303a arranged on the fixed box 301, an air injection cylinder 303b arranged at the bottom of the air inlet pipe 303a, a sealing portion 303c elastically arranged inside the air injection cylinder 303b, the sealing portion 303c is elastically connected to the bottom of the air injection cylinder 303b through a spring, and a one-way valve 303d arranged in the air inlet pipe 303a and on the air injection cylinder 303b;

[0041] The locking unit 300 also includes a driving assembly 304 arranged between the end of the sealing part 303c and the locking ring 202c, wherein the driving assembly 304 can control the sealing part 303c to move. When the sealing part 303c moves, the gas in the gas injection cylinder 303b will enter the fixed box 301 through the one-way valve 303d in the air inlet pipe 303a. When the driving assembly 304 is separated from the sealing part 303c, the sealing part 303c pops up. At this time, the outside air will be drawn into the inside of the gas injection cylinder 303b through the one-way valve 303d on the gas injection cylinder 303b, so that the sealing part 303c can be squeezed into the fixed box 301 when it moves next time.

[0042] The sealing portion 303c includes a piston plate 303c-1 sealingly fitted with the first groove 303b-1, and a long rod 303c-2 connected to the piston plate 303c-1.

[0043] Furthermore, the driving assembly 304 includes a driving rod 304a arranged on the locking ring 202c, and a pressure plate 304b arranged at the end of the long rod 303c-2; the driving rod 304a cooperates with the pressure plate 304b, wherein when the aviation soft wire 204 is pulled out, it will drive the winding roller 202 to rotate, so that the locking ring 202c drives the driving rod 304a to rotate, and the driving rod 304a will intermittently contact and resist the pressure plate 304b. When the pressure plate 304b is squeezed, it will push the sealing plate to move in the air injection cylinder 303b, thereby injecting air into the fixed box 301. When the aviation soft wire 204 is pulled out to the ground, the airbag 302 will expand and resist the locking ring 202c, preventing the winding roller 202 from automatically retracting the aviation soft wire 204.

[0044] Among them, when conducting a test, first climb up and pull the aviation soft wire 204 to the ground, and then plug and test it with a detection device. When the test is completed, climb up again to open the fixing box 301, so that the airbag 302 retracts. At this time, the winding roller 202 can automatically rotate to reel in the aviation soft wire 204 under the elastic force of the coil spring 203. At the same time, the locking ring 202c drives the driving rod 304a to intermittently contact the pressure plate 304b. At this time, the driving rod 304a will pull the pressure plate 304b, so that the piston plate 303c-1 leaves the gas injection cylinder 303b, and at the same time, it will provide resistance to the rotation of the winding roller, control the speed of the recovery of the aviation soft wire 204, and avoid its excessive speed causing collision, causing damage to the joint; the piston plate 303c-1 will pull the spring when it leaves the gas injection cylinder 303b. When the driving rod 304a is separated from the pressure plate 304b, the piston plate 303c-1 automatically contacts the gas injection cylinder 303b under the elastic force of the spring.

[0045] The remaining structures are the same as those of Example 1.

[0046] Example 3, reference Figure 4 and Figure 5 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the pressure plate 304b is U-shaped and is rotatably connected to the long rod 303c-2; the driving assembly 304 includes a limit block 304c arranged on the long rod 303c-2 and matched with the pressure plate 304b, and a spring 304d arranged between the long rod 303c-2 and the pressure plate 304b. When the aviation soft wire 204 is pulled out, the driving rod 304a is against the pressure plate 304b, and the pressure plate 304b is against the limit block 304c. At this time, the driving rod 304a can push The movable long rod 303c-2 and the piston plate 303c-1 move to inject air into the fixed box 301. When the aviation soft wire 204 is retracted, the driving rod 304a and the pressure plate 304b are against each other. At this time, the pressure plate 304b will move in the opposite direction of the limit block 304c. At this time, the pressure plate 304b will squeeze the spring 304d to rotate, so that the pressure plate 304b can be quickly separated from the driving rod 304a. At this time, the pressure plate 304b does not need to be below the central axis of the locking ring 202c in the initial state, and the installation position of the pressure plate 304b is more diverse.

[0047] Furthermore, a first groove 303b-1 and a second groove 303b-2 are provided inside the gas injection cylinder 303b, and the inner diameter of the second groove 303b-2 is larger than that of the first groove 303b-1. The piston plate 303c-1 is sealed and fitted with the first groove 303b-1. In the initial state, the piston plate 303c-1 is located in the second groove 303b-2, and the end is in contact with the first groove 303b-1. When the aviation cord 204 is pulled out, the piston plate 303c-1 is inserted into the first groove 303b-1 to inject gas into the fixed box 301. When the piston aviation cord 204 is wound up, the piston plate 303c-1 leaves the first groove 303b-1 and slides in the second groove 303b-2. The second groove 303b-2 can protect the piston plate 303c-1.

[0048] A sliding rod 303e is provided at the bottom of the first groove 303b-1, and the sealing portion 303c is slidably inserted in the piston plate 303c-1 and the long rod 303c-2. The sliding rod 303e can make the piston plate 303c-1 move more smoothly.

[0049] A pressure relief valve 305 is provided on the fixed box 301, which can detect the pressure in the fixed box 301 and automatically relieve pressure and deflate. In the initial state, the aviation soft line 204 is wound, and the pressure in the fixed box 301 is the initial pressure. When the aviation soft line 204 is pulled out to the ground, the airbag 302 expands and resists the locking ring 202c to block the rotation of the locking ring 202c. At this time, the pressure in the fixed box 301 is the locking pressure. After the detection is completed, the aviation soft line 204 continues to be pulled out. At this time, air will be injected into the fixed box 301 again, and the internal pressure increases, triggering the pressure relief valve 305 to work and relieve pressure. At this time, the internal pressure of the fixed box 301 is the critical pressure. After the pressure relief valve 305 relieves pressure, the internal pressure of the fixed box 301 returns to the initial pressure. At this time, the airbag 302 is retracted. When the aviation soft line 204 is released, the winding roller 202 can rotate to automatically recycle the aviation soft line 204.

[0050] The remaining structure is the same as that of Example 2.
