DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Please refer to Figures 1 to 4, in this practical embodiment, a portable automatic oil cleanliness detection device includes a portable box 1 and a detector body 2 disposed in the portable box 1. The automatic oil cleanliness detector is a device of the prior art. A fixed bottom frame 3 is fixedly connected to the bottom of the portable box 1. A folding mechanism is provided inside the fixed bottom frame 3. Two symmetrically arranged leg plates 4 are hingedly connected to the lower walls on both sides of the fixed bottom frame 3. Four ends of the folding mechanism are respectively hingedly connected to the side walls of the four leg plates 4. The leg plates 4 are of a hollow structure, and an adjusting mechanism is provided in the leg plates 4 to fold and store the leg plates 4 for easy carrying;

[0023] The folding mechanism includes a handwheel rod 5 inserted into and rotatably connected to one side of the fixed bottom frame 3. One end of the handwheel rod 5 is fixedly connected to a bidirectional lead screw 6. Two symmetrically arranged nut blocks 7 are threadedly connected to the bidirectional lead screw 6. Two connecting rods 8 are fixedly connected to both sides of the two nut blocks 7. Two symmetrically arranged support rods 9 are fixedly connected to the inner wall of the fixed bottom frame 3. Two sliding sleeves 10 are sleeved on each of the two support rods 9. One ends of the four connecting rods 8 are respectively fixedly connected to the four sliding sleeves 10. The lower ends of the four sliding sleeves 10 are respectively hingedly connected to swing rods 11. One ends of the four swing rods 11 are respectively hingedly connected to the side walls of the four leg plates 4. When using the detector body 2 to automatically detect the oil cleanliness, first rotate the handwheel rod 5 to drive the bidirectional lead screw 6 to rotate. Since the bidirectional lead screw 6 is threadedly connected to the two nut blocks 7 respectively, at this time, the two nut blocks 7 are forced to displace in opposite directions, thereby driving the sliding sleeves 10 fixed to the connecting rods 8 to displace on the support rods 9. At this time, the swing rods 11 can be pushed to swing, and then the leg plates 4 are pushed to swing on the fixed bottom frame 3 until they are vertical, so as to stably place the device, prevent the bottom of the portable box 1 from being worn, extend the service life, and the adjustment operation is convenient and simple, and the positioning support is stable.

[0024] Such as Figure 2 And Figure 3As shown in the figure: The adjusting mechanism includes a guide block 12 that is slidably connected to the inner wall of the support leg plate 4. A first spring 13 is fixedly connected between the guide block 12 and the inner top wall of the support leg plate 4. A adjusting leg 14 is fixedly connected to the lower side of the guide block 12. A sliding cavity 15 is formed in the side wall of the adjusting leg 14. A T-shaped clamping block 16 is slidably connected to the inner wall of the sliding cavity 15. A second spring 17 is fixedly connected between the T-shaped clamping block 16 and the inner wall of the sliding cavity 15. A plurality of uniformly arranged clamping holes 18 are formed in one side of the support leg plate 4 from top to bottom in sequence. One end of the T-shaped clamping block 16 penetrates and is inserted into one of the clamping holes 18. When encountering uneven ground, the T-shaped clamping block 16 is pushed to retract into the sliding cavity 15. At this time, the second spring 17 is compressed and contracts to generate elastic force until the T-shaped clamping block 16 is separated from the clamping hole 18. At this time, by the elastic force of the first spring 13, the adjusting leg 14 can be pushed out of the support leg plate 4. When it is pushed to a suitable position, by the elastic force of the second spring 17, the T-shaped clamping block 16 can be automatically inserted into the corresponding clamping hole 18 for clamping and positioning, so as to realize the adjustment of the length of the support leg, so that on uneven ground, the device can also be adjusted to a horizontal state to ensure the stability of the work of the detector body 2.

[0025] As Figure 4 shown: One end of the adjusting leg 14 located outside the support leg plate 4 is fixedly connected with a support bottom plate 19, making the support more stable.

[0026] As Figure 3 shown: A through hole is formed in the side wall of the fixed bottom frame 3. The handwheel rod 5 passes through the through hole. The through hole is rotationally connected with the handwheel rod 5 through a bearing member, facilitating the rotation of the handwheel rod 5.

[0029] As Figure 1 shown: Storage boxes 21 for storing the accessories of the detector body 2 are fixedly connected to both side walls of the portable box 1, facilitating storage.

[0030] Working principle: When using the detector body 2 to automatically detect the oil cleanliness, first rotate the handwheel rod 5 to drive the bidirectional lead screw 6 to rotate. Since the bidirectional lead screw 6 is respectively threadedly connected to two nut blocks 7, at this time, the two nut blocks 7 are forced to displace in opposite directions, thereby driving the sliding sleeve 10 fixed to the connecting rod 8 to displace on the support rod 9. At this time, the swing rod 11 can be pushed to swing, and then the support leg plate 4 is pushed to swing on the fixed bottom frame 3 until it is vertical, so as to stably place the device, prevent the bottom of the portable box 1 from being worn, extend the service life, and the adjustment operation is convenient and simple, and the positioning support is stable;

[0031] Secondly, when encountering uneven ground, push the T-shaped block 16 to retract into the sliding cavity 15. At this time, the second spring 17 is compressed and contracted to generate elastic force until the T-shaped block 16 is separated from the card hole 18. At this time, by the elastic force of the first spring 13, the adjusting leg 14 can be pushed out of the support leg plate 4. When it is pushed to the appropriate position, by the elastic force of the second spring 17, the T-shaped block 16 can be automatically inserted into the corresponding card hole 18 for clamping and positioning, and the length of the support leg part can be adjusted, so that on uneven ground, the device can also be adjusted to be horizontal to ensure the stability of the detector body 2 during operation.
