[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1 , Figure 2 and Figure 5 The utility model provides an embodiment: a general troubleshooting device for a natural gas engine, comprising a detector 1, a protective mechanism 2 is arranged on the upper side of the detector 1, a tooth groove 4 is provided at one side of the detector 1, a connecting rod 6 is rotatably connected to the inner wall of the detector 1, one end of the connecting rod 6 passes through the inner wall of the tooth groove 4, and a uniformly distributed limiting groove 9 is opened on the outer periphery of one end of the connecting rod 6, a plurality of moving blocks 15 are slidably connected in the plurality of limiting grooves 9, one end of the plurality of moving blocks 15 is fixedly connected to one end of a spring 10, and the plurality of springs 10 are fixedly connected to one end of the spring 10.

[0036] Specifically, the staff can pull the pull ring 7 outwards and drive the connected gear ring 5 to move through the pull rod 8. When the gear ring 5 is out of the tooth groove 4, the staff can pull the cable 13 and connect the connector 12. In the process of pulling the cable 13, the connecting rod 6 will be driven to rotate. When the connecting rod 6 rotates, the moving block 15 will be driven to rotate through the limit groove 9. When the moving block 15 rotates, the connected gear ring 5 will be driven to rotate. Since the gear ring 5 will compress the spring 2 10 through the moving block 15 when moving, when the cable 13 is stretched to a sufficient length, the staff can release the pull ring 7. At this time, under the action of the spring 2 10 The toothed ring 5 can be pushed to reset and engage with the tooth groove 4, so that the connecting rod 6 can be positioned, and then the length of the cable 13 can be positioned. At the same time, under the action of the limiting rod 11, the moving block 15 can also be limited to ensure the stability of the movement of the moving block 15 and its connecting parts, and prevent the spring 10 from bending after being compressed. When the cable 13 needs to be stored, it is only necessary to pull the toothed ring 5 out of the tooth groove 4 again, so that the connecting rod 6 can be rotated. When the connecting rod 6 rotates, the cable 13 can be reeled in, thereby achieving the effect of facilitating the storage of the cable 13 and adjusting its length.

[0037] Reference Figure 1 , Figure 3 and Figure 4 , the protection mechanism 2 includes a connecting plate 209, which is slidably connected to the inner wall of the detector 1, and a protective cover 201 is fixedly connected to the top of the connecting plate 209. Both sides of the protective cover 201 are fixedly connected with fixed blocks 202, and the two fixed blocks 202 are penetrated into the detector 1. The inner walls of the two fixed blocks 202 are slidably connected with movable plates 205, and the front and rear parts of the close sides of the two movable plates 205 are fixedly connected with one end of a spring 208, and the other ends of the two springs 208 are fixedly connected to the inner wall of the fixed block 202, and the two movable plates 205 are fixedly connected with a card block 206 on the away side, and the away ends of the two card blocks 206 penetrate into the detector 1; the front and rear parts of the two movable plates 205 are penetrated by guide rods 207, and both ends of the multiple guide rods 207 are fixedly connected to the inner wall of the fixed block 202; the top walls of the two movable plates 205 are fixedly connected with a dial plate 203, and the tops of the two dial plates 203 penetrate the top wall of the fixed block 202;

[0038] Specifically, after the cable 13 is stored, the staff can press down the protective cover 201 and insert the fixed block 202 into the detector 1. During the insertion of the fixed block 202, the detector 1 will apply pressure to the card block 206 and push the card block 206 to move into the fixed block 202. When the card block 206 moves, it will drive the connected moving plate 205 to move. When the moving plate 205 moves, it can compress the spring 1 208. Therefore, when the fixed block 202 is fully inserted, the card block 206 will lose pressure. At this time, under the action of the spring 1 208, the moving plate 205 will be pushed in. When the movable plate 205 moves, the card block 206 can be reset and engaged with the detector 1. At the same time, under the action of the guide rod 207, the stability of the movement of the movable plate 205 can be guaranteed, and the spring 208 can be limited to prevent it from bending, so that the protective cover 201 can be fixed and the cable 13 and the connector 12 can be protected. When the protective cover 201 needs to be opened, it is only necessary to push the dial plate 203 to drive the movable plate 205 and the card block 206 to move. When the card block 206 cancels the limit on the detector 1, the protective cover 201 can be pulled upwards.

[0039] Reference Figure 1 , Figure 4 and Figure 5 The front wall of the detector 1 is fixedly connected with a display screen 3; positioning frames 14 are engaged on both sides of the joint 12, and the two positioning frames 14 are fixedly connected to the inner wall of the detector 1; the lower sides of the two card blocks 206 away from each other are provided with inclined surfaces;

[0040] Specifically, by providing a display screen 3, it is convenient for the staff to control the detector 1 and observe the troubleshooting situation; by providing a positioning frame 14, the connector 12 can be limited to prevent the connector 12 from shaking in the detector 1; by providing an inclined surface, it can make it easier to push the block 206 to move after the detector 1 contacts the block 206.

[0041] Reference Figure 1 , Figure 3 and Figure 5 , both side walls of the detector 1 are provided with a slide groove 211, a rotating shaft 210 is passed through the lower part of the connecting plate 209, both ends of the rotating shaft 210 pass through the two side walls of the connecting plate 209 and are rotatably connected with the rotating wheels 204, and the two rotating wheels 204 are rotatably connected to the inner wall of the slide groove 211;

[0042] Specifically, by providing the rotating shaft 210 and the rotating wheel 204, the friction can be reduced when pulling the protective cover 201, so that the movement of the protective cover 201 and the connecting plate 209 is smoother, and the travel can be limited by the sliding groove 211 to prevent it from detaching from the detector 1.

[0043] Working principle: In actual use, by pulling the toothed ring 5 outward to disengage it from the toothed groove 4, the staff can pull the cable 13 and connect the connector 12. In the process of pulling the cable 13, the connecting rod 6 will rotate, and drive the toothed ring 5 to rotate through the limit groove 9 and the moving block 15. Since the toothed ring 5 will compress the spring 2 10 through the moving block 15 when moving, when the cable 13 is stretched to a sufficient length, the staff can loosen the toothed ring 5, and under the action of the spring 2 10, the toothed ring 5 is reset and engaged with the toothed groove 4, so that the connecting rod 6 can be positioned, and then the length of the cable 13 can be positioned. When the cable 13 needs to be stored, it is only necessary to pull the toothed ring. 5 and rotate, the cable 13 can be rolled up, so as to achieve the effect of accommodating the cable 13 and adjusting the length; in addition, when the cable 13 is stored, the staff can press down the protective cover 201 and insert the fixing block 202 into the detector 1. During the insertion of the fixing block 202, the detector 1 will press the card block 206 and drag the card block 206 to move into the fixing block 202. Since the card block 206 compresses the spring 1 208 when it moves, when the fixing block 202 is fully inserted, the card block 206 can be reset and engaged with the detector 1 under the action of the spring 1 208, so that the protective cover 201 can be fixed and the cable 13 and the connector 12 can be protected.
