DETAILED DESCRIPTION

[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor are within the protection scope of the utility model.

[0019] A kind of sensor quick replacement connector, such as Figs. 1-3As shown, it comprises a first connecting piece 1, the outer side of the left part of the first connecting piece 1 is provided with threads, the first connecting piece 1 is a cylindrical structure, a sealing ring 2 is connected to the inner left part of the first connecting piece 1, two symmetrical inclined surface structures 11 are arranged inside the first connecting piece 1, a second connecting piece 3 is connected to the right part of the first connecting piece 1 in a clamping manner, the second connecting piece 3 is a funnel structure, a row of anti-skid grooves is arranged on the outer side of the left part of the second connecting piece 3, a contact piece 4 is connected to the left part of the second connecting piece 3 in a sliding manner, seven needle pins 41 are arranged on the left side of the contact piece 4, a first spring 5 is connected between the contact piece 4 and the second connecting piece 3, the first spring 5 is sleeved on the right part of the contact piece 4, two symmetrical connecting plates 8 are connected to the outer side of the left part of the second connecting piece 3, protrusions 9 are connected to the inner side of the left part of the connecting plates 8, rib plates are connected to the inner side of the connecting plates 8, two symmetrical locking pieces 6 are connected to the left part of the second connecting piece 3 in a sliding manner, the locking pieces 6 can be clamped with the corresponding inclined surface structures 11, and the second spring 7 is connected between the locking piece 6 and the adjacent second connecting piece 3, and the locking piece 6 is connected to the protrusion 9 in a contact manner.

[0020] It should be noted that when the sensor is docked, the device can be used for auxiliary operation, the device can realize quick replacement, and is more convenient to use. First, the two connecting plates 8 need to be pressed, the protrusions 9 need to be pressed against the locking pieces 6, and the second spring 7 needs to be compressed. At this time, the first connecting piece 1 is pulled to the left, the locking pieces 6 are separated from the first connecting piece 1 by relying on the inclined surface structures 11, and unlocking is completed. Then, the first connecting piece 1 is connected to the sensor in a threaded manner, and then the docking end is inserted into the second connecting piece 3 and contacts the right side of the contact piece 4.
