Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the structural schematic diagram of the mounting base special for the shield tail automatic measurement sensor of the present invention includes a sensor 1, a thin nut 2, a fixing base 3, a detachable protective cover 4, a welding base 5, a screw 6, and a collision-proof block 7, wherein the welding base 5 and the collision-proof block 7 are butt-jointed and welded, and in another case, the welding base 5 and the collision-proof block 7 are not welded together, and a distance for accommodating the sensor is separated between the two, and the distance for accommodating the sensor needs to adapt to the mounting of the sensor 1, so as to avoid the direct extrusion of the sensor 1. Welding base 5 and crashproof piece 7 welding are on the shield tail, and fixing base 3 and can dismantle visor 4 and install on welding base 5 through screw 6, and crashproof piece 7, welding base 5 constitute sensor 1's protecting sheathing with can dismantling visor 4 jointly.
In another embodiment, as shown in fig. 4, the two welding bases 5 are divided into two parts, and are placed side by side to leave a long groove between the two welding bases 5, which has the same effect on the U-shaped long groove and can accommodate the sensor 1. Compared with the mode that the welding base 5 is of an integral structure, the structure has no difference in connection, and the welding base 5 is separated in function, so that the placing space of the sensor 1 is reserved, and the height of the integral installation base can be reduced.
Referring to fig. 2, the front view of the mounting base for the shield tail automatic measurement sensor of the present invention is a cross-sectional view, wherein the sensor placing space 8 is a space in a marked rectangular frame, the U-shaped long groove 9 is a space pointed by a reference number in the drawing, and the U-shaped notch 10 is a space pointed by a reference number in the drawing. After the sensor 1 passes through the round hole 13, the sensor is screwed and fixed by the thin nuts 2 distributed on two sides of the fixed seat 3, at least one thin nut 2 is distributed on each side of the fixed seat 3, the sensor 1 is effectively prevented from shaking in the longitudinal direction, the thin nut 2 is clamped on two sides, preferably, the threads on the periphery of the sensor 1 are matched and contacted, and the internal threads formed by the embedded matching round hole 13 can be selected.
