Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-4, a flexible probe rod of a natural gas detection instrument includes a flexible probe rod 2 connected to an upper end of a detection device main body 1, a base 3 is fixedly connected to a periphery of a probe end of the flexible probe rod 2, a housing 4 is sleeved on an outer surface of the base 3 and slidably connected to the outer surface of the base 3, a torsion rotating shaft is fixedly connected to a surface of the housing 4, a top cover 5 is fixedly connected to the other side of the torsion rotating shaft, a limiting groove is formed in an outer surface of the base 3, and a limiting block 9 is fixedly connected to a periphery of a bottom end of the base 3. Because the top cover 5 can fall to and cover at the probe end under torsion spring's effect, protect the probe end of flexible detecting rod 2, pollution such as impurity is kept apart outside, prevent that the filter screen of probe from taking place to block up, when needing to use, shell 4 slides down, base 3 promotes top cover 5, open its back, the probe exposes, until top cover 5 offsets with the spacing groove of base 3 surface, prescribe a limit to the position of top cover 5 and shell 4, this design is protected the probe end of flexible detecting rod 2 further through top cover 5, the protective capacities of equipment has been improved, top cover 5 after opening is fixed through the spacing groove simultaneously, avoided influencing the use of equipment because the slip of shell 4.

As shown in fig. 2 and fig. 3, it is further, a plurality of spouts 6 have been seted up to the upper surface of base 3, the inside of a plurality of spouts 6 all communicates each other, sliding connection has many slide bars 7 in the spout 6, the top and the equal rigid coupling in bottom of many slide bars 7 have solid fixed ring 8, slide bar 7 and solid fixed ring 8 through setting up the slip lift in base 3, utilize the effect that blocks of slide bar 7 and the solid fixed ring 8 on its top, can keep off in the middle of pipeline and probe when surveying, prevent that the touching of test procedure probe and pipeline wall from being infected with greasy dirt and dust, the barrier propterty of structure has further been optimized.

As shown in fig. 4, further, a rubber ring 10 is inserted and connected at the opening of the base 3, and the rubber ring 10 is fixedly connected with the inner wall of the top cover 5. Because the rubber ring 10 is matched with the opening of the base 3, the rubber ring 10 can be inserted into the opening of the base 3 when the top cover 5 is closed, and the rubber ring is blocked outside the probe filter screen, the design enables the friction force between the top cover 5 and the base 3 to be increased, the top cover 5 cannot be easily opened and closed, and the protection performance of the structure is improved.

As shown in fig. 2 and 4, further, the outer surface of the fixing ring 8 at the top end of the sliding rod 7 is provided with anti-slip threads, and the periphery of the outer surface of the top cover 5 is also provided with anti-slip threads. The design increases the friction force between the outer surface of the fixing ring 8 at the top end of the sliding rod 7 and the outer surface of the top cover 5, so that a user can conveniently apply force to open the top cover 5 or pull the sliding rod 7, and the use experience is optimized.

As shown in fig. 3, further, rubber anti-slip layers are fixedly connected to the periphery of the fixing ring 8 at the bottom end of the sliding rod 7 and the surface of the limiting block 9. This design is used for increasing the frictional force and the buffer power on solid fixed ring 8 week side and stopper 9 surface, because the rubber buffer layer of solid fixed ring 8 week side offsets with spout 6 for the user needs the application of force to pull just can drive the slip of slide bar 7, and then when needs come the fender in the middle of pipeline and the probe through solid fixed ring 8 of slide bar 7 and outer end, slide bar 7 can not slide easily, influences the result of use. In a similar way, the rubber buffer layer on the surface of the limiting block 9 is abutted to the inner wall of the shell 4, so that the shell 4 is prevented from freely sliding to influence the use of the equipment.

The working principle is as follows: the top cap 5 can fall to and cover at the probe end under torsion spring's effect, protect the probe opening part of flexible probe rod 2, during the use, the shell 4 slides downwards, base 3 promotes top cap 5 and opens its back, the probe exposes, until top cap 5 offsets with the spacing groove of base 3 surface, prescribe a limit to the position of top cap 5 and shell 4, then upwards pull the solid fixed ring 8 on slide bar 7 top, pull out slide bar 7, because the rubber skid resistant course of solid fixed ring 8 week side rigid coupling of slide bar 7 bottom makes slide bar 7 can not slide easily, slide bar 7 keeps off in the middle of pipeline and probe during the detection, prevent that probe and pipeline wall touch and be infected with greasy dirt and dust in the testing process, further optimized the barrier propterty of structure.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
