Technical Field

[0001] The utility model relates to the technical field of gas test probes, in particular to a test probe that is easy to carry. Background Art

[0002] The gas pipe is a special pipeline for transporting combustible gas. It is a metal gas pipe hose that replaces the traditional clip-on rubber hose. It can solve the defects of rubber hoses that are easy to fall off, easy to age, easy to be bitten by insects, and have a short service life. During the construction of the gas pipeline, a test equipment is usually required to test the gas pipeline. During the test, a probe is usually required to connect the test equipment to test the gas pipeline.

[0003] Existing test probes are usually integrated. The probes are too long and require a large storage space when carried and moved, making it inconvenient to carry and transfer them when testing gas pipeline construction, reducing the convenience of the probes in gas pipeline testing.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4The utility model provides a portable testing probe, comprising a rod body 1, a top rod 2 being hinged to the top of the rod body 1, a first connecting rod 3 for connecting to a testing device being provided at the top of the top rod 2, a combination structure 4 for facilitating the combination of the top rod 2 and the rod body 1 being provided at the bottom end of the rod body 1, a connecting seat 5 being bolted to the bottom end of the connecting seat 5 being hinged to a fixing seat 6 being hinged, a bottom end of the fixing seat 6 being fixedly connected to a bottom rod 7, a section of the bottom rod 7 being provided with a second connecting rod 8 for connecting to a testing device, and a positioning structure 9 being provided at the top end of the fixing seat 6 for positioning the position of the bottom rod 7 after being combined with the rod body 1.

[0024] When folding, the rotating assembly structure 4 cancels the fixation between the top rod 2 and the rod body 1. The rod body 1 and the top rod 2 are hinged together, allowing them to fold together. The positioning structure 9 at the bottom is then pulled to cancel the fixation between the connecting seat 5 and the fixing seat 6. The connecting seat 5 and the fixing seat 6 are hinged together, allowing the rod body 1 and the bottom rod 7 to fold together. This allows the probe to be folded three times when folded together, further shortening the probe's overall length, reducing the space required for carrying and moving, and improving the convenience of the probe when testing gas pipelines.

[0025] The combined structure 4 includes a threaded seat 41 and a threaded sleeve 42. The threaded seat 41 is fixedly connected to the bottom end of the push rod 2. A through hole is opened at the bottom end of the threaded sleeve 42. The inner cavity of the through hole of the threaded sleeve 42 is inserted and slid with the outer surface of the rod body 1. The inner cavity of the threaded sleeve 42 is threadedly connected to the outer surface of the threaded seat 41. After the rod body 1 and the push rod 2 are combined, the threaded sleeve 42 is pushed upward to contact the lower surface of the threaded seat 41. Then, the threaded sleeve 42 is rotated to be connected through the thread, so that the threaded sleeve 42 and the threaded seat 41 are locked, thereby completing the fixation between the push rod 2 and the rod body 1.

[0026] A slot 10 is provided at the top of the rod body 1, and a clamping block 11 is fixedly connected to one end of the top rod 2. The clamping block 11 is engaged with the inner cavity of the slot 10. After the rod body 1 and the top plate are combined, the clamping block 11 is driven to insert into the inner cavity of the slot 10. Through the cooperation between the clamping block 11 and the slot 10, the angle deviation after the rod body 1 and the top rod 2 are combined is avoided, and the stability of the rod body 1 and the top rod 2 after combination is improved.

[0027] The positioning structure 9 includes a movable groove 91 and a fixed block 92. A positioning rod 93 slides in the inner cavity of the movable groove 91. Both ends of the positioning rod 93 are slidably connected to the inner cavity of the movable groove 91. A positioning pin 94 is provided on the outer surface of the positioning rod 93. The other end of the positioning pin 94 passes through the movable groove 91 and is fixedly connected to the limiting block 95. The fixed block 92 is fixedly connected to the top of the fixing seat 6. Pushing the limiting block 95 drives the positioning pin 94 to move inward, so that the positioning pin 94 drives the positioning rod 93 to move out of the inner cavity of the limiting block 95, canceling the fixing effect between the connecting seat 5 and the fixing seat 6, and the rod body 1 and the bottom rod 7 can be folded. During assembly, after the rod body 1 and the bottom rod 7 are combined, the connecting seat 5 and the fixing seat 6 are combined, and the limiting block 95 is pulled outward to drive the positioning rod 93 to move to the inner cavity of the fixed block 92, completing the positioning, and realizing the assembly of the rod body 1 and the bottom rod 7.

[0028] The shape of the fixing block 92 is L-shaped, and the top of the fixing block 92 is beveled. Through the shape of the fixing block 92, the connecting seat 5 and the fixing seat 6 are fixed. When the fixing seat 6 is covered, the positioning rod 93 contacts the bevel on the fixing block 92. At this time, the positioning rod 93 will slide inward through the bevel on the fixing block 92. When it moves to the bottom end of the fixing block 92, the positioning block is pulled outward to drive the positioning rod 93 to move to the inner cavity of the fixing block 92, and the fixation is completed.

[0029] The outer surface of the positioning pin 94 is sleeved with a spring 12, and the spring 12 is located between the limit block 95 and the connecting seat 5. Through the setting of the spring 12, when the positioning rod 93 slides inward through the oblique cut surface of the fixed block 92, the positioning pin 94 can drive the limit block 95 at the other end to squeeze the spring 12. When the positioning rod 93 moves to the bottom end of the fixed block 92, the positioning rod 93 is released to make the spring 12 rebound and push the limit block 95 to reset, driving the positioning rod 93 to move toward the inner cavity of the fixed block 92 to complete the positioning.

[0030] A sliding groove 13 is provided on both sides of the outer surface of the connecting seat 5, and one end of the sliding groove 13 extends to the inner cavity of the adjustment groove. The inner cavity of the sliding groove 13 is slidably connected to the outer surface of the positioning rod 93. The setting of the sliding groove 13 supports both ends of the positioning rod 93, thereby improving the stability of the positioning rod 93 during movement.

[0031] The method of using the present utility model is as follows: when folding, the threaded sleeve 42 is rotated counterclockwise, and the threaded sleeve 42 is connected to the threaded seat 41 through the thread, so that the threaded sleeve 42 moves downward on the rod body 1, canceling the fixation of the top rod 2, and then the top rod 2 is folded, and the limit block 95 is pressed to squeeze the positioning rod 93 through the positioning pin 94, and the positioning rod 93 moves outward and out of the inner cavity of the fixing block 92, canceling the fixing effect between the fixing seat 6 and the connecting seat 5, so that the rod body 1 and the bottom rod 7 can be folded. When assembling, the rod body 1 and the top rod 2 are combined, the card block 11 is inserted into the inner cavity of the card slot 10, and then the threaded sleeve 42 is moved upward to contact the threaded seat 41, and the threaded sleeve 42 is rotated clockwise to lock the threaded seat 41, completing the assembly of the rod body 1 and the top rod 2. The rod body 1 is combined with the bottom rod 7 so that the connecting seat 5 covers the fixing seat 6. The connecting seat 5 drives the positioning rod 93 to contact the fixing seat 6. When the positioning rod 93 slides inward through the oblique cut surface of the fixing block 92, the limiting block 95 at the other end can be driven by the positioning pin 94 to squeeze the spring 12. When the positioning rod 93 moves to the bottom end of the fixing block 92, the positioning rod 93 is released, causing the spring 12 to rebound and push the limiting block 95 to reset, driving the positioning rod 93 to move toward the inner cavity of the fixing block 92 to complete the positioning, thereby realizing that the probe can be folded three times when stored, further shortening the overall length of the probe, reducing the space required for carrying and moving, and improving the convenience of the probe when testing the gas pipeline.

[0032] The first connecting rod 3 and the top rod 2 are hinged by the cooperation of the connecting frame and the bolts. When storing, the first connecting rod 3 can also be folded.
