Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flaw detection probes, in particular to a switching device for a portable flaw detection probe. Background Art
[0002] The flaw detector is suitable for wet magnetic particle detection of various small and medium-sized parts such as crankshafts, camshafts, spline shafts, etc. The surface and near-surface cracks and minor defects caused by casting, quenching, processing, fatigue, etc. are the preferred model for single-piece inspection, small-batch sampling, and large-volume inspection.
[0003] When using traditional flaw detection equipment, the flaw detection probe needs to be connected to the flaw detection host, which requires the use of connecting wires and adapters. However, when using traditional equipment, the connection between the connecting wire and the adapter is only fixed by the friction between the two. During long-term use, the friction between the adapter and the connecting wire decreases, which will cause the connecting wire to loosen, thereby affecting the normal operation of the equipment. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a switching device for a portable flaw detection probe, which has the advantages of easy use and stable connection, and solves the problems raised by the above-mentioned background technology.
[0005] The utility model provides the following technical solutions: a switching device for a portable flaw detection probe, comprising a probe body, an indicator light fixedly mounted on the top of the probe body, a detection rod fixedly mounted on the outer wall of the probe body, an adapter mounted on the outer wall of the probe body, a connector movably sleeved on the inner cavity of the adapter, a fixing cylinder fixedly mounted on the top of the adapter, a limit rod movably sleeved on the inner cavity of the fixing cylinder, a limit ring fixedly mounted on the outer wall of the limit rod, a push spring movably sleeved on the outer wall of the limit rod, a pressure switch fixedly mounted on the top of the limit rod, a fixing plate fixedly mounted on the top of the limit rod, a trigger rod fixedly mounted on the bottom of the fixing plate, the outer wall of the fixing plate is rotatably connected to a connecting plate, and the outer wall of the connecting plate is rotatably connected to a push plate.
[0006] As a preferred technical solution of the utility model: a limiting ring is fixedly assembled on the outer edge of the fixing tube close to one end of the fixing plate, and the inner wall diameter of the limiting ring matches the outer wall diameter of the limiting rod.
[0007] As a preferred technical solution of the utility model: a limiting hole is provided on the top of the connector, and the inner wall diameter of the limiting hole matches the outer wall diameter of the limiting rod.
[0008] As a preferred technical solution of the utility model: a controller is fixedly mounted on the top of the adapter, and the controller is electrically connected to the pressure switch and the indicator light respectively.
[0009] As a preferred technical solution of the utility model: the outer wall of the push plate is rotatably connected to the outer walls of the connecting plates on the upper and lower sides respectively, and the connecting plates and the fixing plates are both made of ABS plastic.
[0010] As a preferred technical solution of the utility model: there are four limit rods, and the four limit rods are respectively installed in the inner cavities at the top and bottom of the adapter.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The adapter of the portable flaw detection probe has a fixing tube and a pull rod arranged on the outer wall of the adapter. The pull rod enters the inner cavity of the connector under the action of a push spring, thereby locking the connector. The pull rods arranged in the upper and lower directions can better lock the connector and the adapter, avoiding the traditional equipment relying on the friction between the connector and the adapter for fixing, and better connecting the connector and the adapter.
[0013] 2. The adapter of the portable flaw detection probe has a pressure switch arranged on the top of the adapter and a trigger rod arranged on the outer wall of the fixed plate. When the limit rod stably limits the connector, the trigger rod triggers the pressure switch. Once the limit rod moves outward during use, the trigger rod cannot contact the pressure switch. At this time, the indicator light goes out, indicating that there is a gap in the fixation of the connector by the limit rod. The connector can be plugged in in time to better maintain the stability of the connection between the connector and the adapter. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] By setting a fixing cylinder 6 on the outer wall of the adapter 4 and obtaining a limiting rod 7 sleeved in the inner cavity of the fixing cylinder 6, the limiting rod 7 can enter the inner cavity of the connecting head 5 under the push of the push spring 9. At this time, the connecting head 5 can be locked under the action of the limiting rod 7, so that the connecting head 5 can stay stably in the inner cavity of the adapter 4.
[0023] In a preferred embodiment, a limiting ring is fixedly assembled on the outer edge of the fixing tube 6 close to one end of the fixing plate 12 , and the inner wall diameter of the limiting ring matches the outer wall diameter of the limiting rod 7 .
[0024] By means of a limiting ring arranged on the outer edge of the fixed tube 6, the push spring 9 is limited under the action of the limiting ring and the limiting ring 8, so that the push spring 9 is locked on the outer wall of the limiting rod 7, so that the limiting rod 7 can enter the inner cavity of the connecting head 5 under the action of the pushing spring 9, thereby locking the connecting head 5.
[0025] In a preferred embodiment, a limiting hole is provided on the top of the connector 5 , and the inner wall diameter of the limiting hole matches the outer wall diameter of the limiting rod 7 .
[0026] Through the limit hole opened on the top of the connector 5, the limit rod 7 will enter the limit hole under the action of the push spring 9, thereby locking the connector 5, so that the outer wall of the connector 5 is in close contact with the inner wall of the adapter 4, thereby transmitting the current signal.
[0027] In a preferred embodiment, a controller is fixedly mounted on the top of the adapter 4 , and the controller is electrically connected to the pressure switch 10 and the indicator light 2 , respectively.
[0028] Through the controller set on the top of the adapter 4, when the limit rod 7 locks the connector 5 under the action of the push spring 9, the outer wall of the trigger rod 11 will contact the outer wall of the pressure switch 10, thereby triggering the pressure switch 10. At this time, the indicator light 2 can be lit under the action of the controller.
[0029] In a preferred embodiment, the outer wall of the push plate 14 is rotatably connected to the outer walls of the upper and lower connecting plates 13 respectively, and the connecting plates 13 and the fixing plate 12 are both made of ABS plastic.
[0030] By setting the push plate 14 on the outer wall of the connecting plate 13, when the connecting head 5 needs to be unlocked, it is only necessary to press the push plate 14 downwards. Under the action of the connecting plate 13, the fixed plate 12 can be pushed to move, so that the fixed plate 12 pulls the limit rod 7 away from the outer wall of the connecting head 5, and the connecting head 5 can be unlocked, which is very convenient.
[0031] In a preferred embodiment, there are four limiting rods 7 , and the four limiting rods 7 are respectively installed in the inner cavities at the top and bottom of the adapter 4 .
[0032] By providing a plurality of limit rods 7 at the top and bottom of the adapter 4, the connector 5 is locked and fixed from the top and bottom of the adapter 4 respectively under the action of the limit rods 7, so that the connector 5 can be stably and firmly inserted into the inner cavity of the adapter 4, so that the probe body 1 will not be powered off during use.
[0033] Working principle: During the use of the above-mentioned equipment, when the equipment needs to be used for flaw detection, the connector 5 needs to be connected to the outer wall of the probe body 1. At this time, the outer wall of the connector 5 needs to be inserted into the inner cavity of the adapter 4. It is only necessary to push the push plate 14 inward. Under the action of the push plate 14, the connecting plates 13 on both sides move inward, and the fixing plate 12 at the top of the adapter 4 and the fixing plate 12 at the bottom are pushed away from the adapter 4 respectively. When the fixing plate 12 moves in the direction away from the adapter 4, the limit rod 7 will move driven by the fixing plate 12. At this time, the connector 5 can be inserted into the inner cavity of the adapter 4, and then the push plate 14 is released. Under the action of the push spring 9, Push the outer wall of the limit rod 7 into the inner cavity of the connector 5 to lock the connector 5. At this time, the probe body 1 can be used normally. During the normal use of the probe body 1, the trigger rod 11 will stably contact the pressure switch 10 under the action of the fixing plate 12 and the push spring 9, so that the pressure switch 10 is triggered and the indicator light 2 is normally lit. Once the fixing plate 12 moves to the side away from the adapter 4 during use, the outer wall of the trigger rod 11 will leave the top of the pressure switch 10, and the indicator light 2 will not be lit. At this time, the state of the limit rod 7 on the outer wall of the connector 5 can be known, thereby checking the plug-in state of the connector 5 to ensure the normal operation of the equipment.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
