[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0022] Reference Figure 1-4As shown, a portable automobile compressor fault detector includes a protective box 1, a box cover 2 is rotatably installed on the rear side of the upper end of the protective box 1, a telescopic pull rod 13 is fixedly installed on the right end of the protective box 1, and several groups of universal wheels 9 are fixedly installed on the outer side of the lower end of the protective box 1. A battery 4 is fixedly installed on the middle part of the bottom end of the protective box 1, and fixing mechanisms 10 are provided on the front and rear sides of the bottom end of the protective box 1. The battery 4 and the two fixing mechanisms 10 are separated by a partition 3. The partition 3 is fixedly connected to the inner wall of the protective box 1, and a detector body 5 and an automatic wire take-up device 6 are fixedly installed on the top of the partition 3. The automatic wire take-up device 6 is arranged on the right side of the detector body 5. A pair of fixing frames 7 are provided on the front side of the detector body 5. The two fixing frames 7 are symmetrically installed on the top of the partition 3. A wire pulley 8 is rotatably installed inside the fixing frame 7. The two wire pulleys 8 abut against each other and the surfaces of both are provided with arc surfaces 801. When the detector needs to be moved, the fixing mechanism 10 is started, and the electric push rod 1001 in the fixing mechanism 10 is driven to make the supporting cross plate 1012 leave the ground, and the universal wheel 9 contacts the ground. Then, by pulling the telescopic pull rod 13, the device can be moved through the universal wheel 9, which makes it convenient for the user to move the device to the use area, reduces the burden on the user when carrying the fault detection equipment, is convenient to use, and saves time and effort.

[0023] Specifically, in this embodiment, a data cable 501 is fixedly connected to the right end of the detector body 5. The other end of the data cable 501 is wound inside the automatic wire take-up device 6 and extends out to be arranged between two wire reels 8. The device is provided with an automatic wire take-up device 6, which can retract the data cable 501 through an elastic element (such as a spring). The data cable 501 is assisted by the two wire reels 8, so that the data cable 501 is prevented from being tangled when being retracted by the automatic wire take-up device 6. By winding and storing the data cable 501, it is convenient and better stored, and at the same time, it has good dustproof and protective effects on the data cable 501.

[0024] Specifically, in this embodiment, the front and rear inner walls of the protection box 1 are fixedly connected to the limit bars 101 , and the front and rear sides of the bottom plate of the protection box 1 are penetrated by through slots 102 .

[0025] Specifically, in this embodiment, the fixing mechanism 10 includes a pair of electric push rods 1001, and the two electric push rods 1001 are symmetrically installed on the left and right inner walls of the protective box 1. The output end of the electric push rod 1001 is fixedly connected to a connecting plate 1004, and the lower end of the connecting plate 1004 is fixedly connected to a first moving block 1003. The first moving block 1003 is movably installed on the surface of the first slide bar 1002. The two ends of the first slide bar 1002 are respectively fixedly connected to the left and right inner walls of the protective box 1, and the lower end of the first moving block 1003 is fixedly connected to a first connecting seat 1006. A limiting groove 1005 is provided at the outer end of the first moving block 1003. The size of the limiting groove 1005 matches the limiting bar 101. The limiting bar 101 can guide and limit the two first moving blocks 1003 so that they move along a predetermined trajectory to avoid offset, thereby ensuring the stability of the fixing mechanism 10 in the process of driving the supporting cross plate 1012 to move up and down.

[0026] Specifically, in this embodiment, connecting rods 1007 are rotatably installed inside the two first connecting seats 1006, and the two connecting rods 1007 cross each other and are rotatably connected. The other end of the connecting rod 1007 extends through the through slot 102 and is rotatably connected to the second connecting seat 1008. The lower end of the second connecting seat 1008 is fixedly connected to the second moving block 1009, and the second moving block 1009 is movably installed on the surface of the second slide bar 1010. The second slide bar 1010 is fixedly connected between the two mounting frames 1011, and the lower end of the mounting frame 1011 is fixedly connected to the supporting cross plate 1012. By starting the two electric push rods 1001, the two electric push rods 1001 are retracted, and then the first moving block 1003 is driven to move in the opposite direction through the connecting plate 1004. The two first moving blocks 1003 move in the opposite direction and then the two second moving blocks 1009 move in the opposite direction through the two connecting rods 1007. Under the limiting action of the telescopic rod 12, the supporting cross plate 1012 is retracted upward until the supporting cross plate 1012 leaves the ground and the universal wheel 9 contacts the ground. Then, by pulling the telescopic pull rod 13, the device can be moved by the universal wheel 9, which is convenient for the user to move the device to the use area, reducing the burden on the user when carrying the fault detection equipment, making it convenient to use, saving time and effort, and conversely, when the detector needs to be parked, the two electric push rods 1001 are pushed in the opposite direction, so that the supporting cross plate 1012 contacts the ground and the universal wheel 9 is lifted off the ground. The supporting cross plate 1012 and the anti-slip pad 11 cooperate to stably support the detector, making it convenient for the user to use.

[0027] Specifically, in this embodiment, the lower end of the support plate 1012 is fixedly connected to an anti-slip pad 11. The anti-slip pad 11 increases the friction between the support plate 1012 and the ground, thereby increasing the stability of the support plate 1012 and the ground, allowing the detector to be stably supported and convenient for the user. Several sets of telescopic rods 12 are fixedly mounted on the upper end of the support plate 1012, and the other ends of the telescopic rods 12 are fixedly connected to the lower end of the protective box 1. The telescopic rods 12 act as a limiter and guide for the support plate 1012, allowing it to move along a predetermined trajectory.

[0028] The working principle of the present invention is as follows: when the detector needs to be moved, the fixing mechanism 10 is started, and at this time, the two electric push rods 1001 are started, so that the two electric push rods 1001 are retracted, and then the first moving block 1003 is driven to move in the opposite direction through the connecting plate 1004. The two first moving blocks 1003 move in the opposite direction, and then the two second moving blocks 1009 are driven to move in the opposite direction through the two connecting rods 1007. Under the limiting action of the telescopic rod 12, the supporting cross plate 1012 is retracted upward until the supporting cross plate 1012 leaves the ground. The universal wheel 9 contacts the ground, and then by pulling the telescopic pull rod 13, the device can be moved by the universal wheel 9, which is convenient for the user to move the device to the use area, reducing the burden on the user when carrying the fault detection equipment, making it convenient to use, saving time and effort. On the contrary, when the detector needs to be parked, the two electric push rods 1001 are pushed in the opposite direction to make the supporting cross plate 1012 contact the ground and lift the universal wheel 9 off the ground. The supporting cross plate 1012 and the anti-slip pad 11 cooperate to stably support the detector, making it convenient for users to use.

[0029] The device is provided with an automatic wire take-up device 6, which can recycle the data cable 501 through an elastic element (such as a spring). The data cable 501 is assisted by two wire wheels 8, so that the data cable 501 is prevented from being entangled when being recycled by the automatic wire take-up device 6. By winding and storing the data cable 501, better storage is facilitated, and the data cable 501 has good dust-proof and protective effects.
