Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of anti-loose structure of magnetic support vibration transducer, utilize this structure to guarantee the connection reliability of magnetic support and vibration transducer, avoid the loosening of magnetic support and vibration transducer, reduce the composition of vibration signal spectrum analysis Middle and low frequency noise, improved the accuracy that vibration equipment detects.
For solving the problems of the technologies described above, anti-loose structure involving vibrations sensor and the magnetic support of the utility model magnetic support vibration transducer, described magnetic support center is provided with screw rod, described vibration transducer base is that sexangle bottom center are provided with screw, the screw rod of described magnetic support is twisted in the screw of described vibration transducer base, this structure also comprises elastic opening annular pad and two fins, described two fins are symmetrically set in respectively the outer ring of described elastic opening annular pad and to the centroclinal setting of elastic opening annular pad, described two fins arrange in opposite directions by the pros and cons of described elastic opening annular pad, described elastic opening annular pad is located between described vibration transducer and magnetic support and described two fins are fitted respectively described vibration transducer base side and magnetic support side.
Further, the opening both sides of above-mentioned elastic opening annular pad are provided with elasticity subtended angle.
Further, the outer ring of above-mentioned elastic opening annular pad is sexangle limit.
Further, above-mentioned two fin shape are right-angle triangles, and the right-angle side of described fin connects described elastic opening annular pad outer ring.
Because the anti-loose structure of the utility model magnetic support vibration transducer has adopted technique scheme, be this structure involving vibrations sensor and magnetic support, described magnetic support center is provided with screw rod, described vibration transducer base is that sexangle bottom center are provided with screw, the screw rod of described magnetic support is twisted in the screw of described vibration transducer base, this structure also comprises elastic opening annular pad and two fins, described two fins are symmetrically set in respectively the outer ring of described elastic opening annular pad and slope inwardly, described two fins arrange in opposite directions by the pros and cons of described elastic opening annular pad, described elastic opening annular pad is located between described vibration transducer and magnetic support and described two fins are fitted respectively described vibration transducer base side and magnetic support side.This structure is guaranteed the connection reliability of magnetic support and vibration transducer, avoids the loosening of magnetic support and vibration transducer, has reduced the composition of vibration signal spectrum analysis Middle and low frequency noise, has improved the accuracy that vibration equipment detects.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the anti-loose structure schematic diagram of the utility model magnetic support vibration transducer;
Fig. 2 is the structural representation of this structure Elastic open annular pad and fin.
Embodiment
As depicted in figs. 1 and 2, anti-loose structure involving vibrations sensor 1 and the magnetic support 2 of the utility model magnetic support vibration transducer, described magnetic support 2 centers are provided with screw rod 21, the base 11 of described vibration transducer 1 is provided with screw 12 for sexangle bottom center, the screw rod 21 of described magnetic support 2 is twisted in the screw 12 of described vibration transducer base 11, this structure also comprises elastic opening annular pad 3 and two fins 4, described two fins 4 are symmetrically set in respectively the outer ring of described elastic opening annular pad 3 and to the centroclinal setting of elastic opening annular pad 3, described two fins 4 arrange in opposite directions by the pros and cons of described elastic opening annular pad 3, described elastic opening annular pad 3 is located between described vibration transducer 1 and magnetic support 2 and described two fins 4 are fitted respectively described vibration transducer base 11 sides and magnetic support 2 sides.
Further, the opening both sides of above-mentioned elastic opening annular pad 3 are provided with elasticity subtended angle.After this elasticity subtended angle is driven plain, make pad there is certain elasticity, thereby screw rod and being threaded of screw are played to certain locking effect.
Further, the outer ring of above-mentioned elastic opening annular pad 3 is sexangle limits.The elastic opening annular sexangle limit of pad and the sexangle base of vibration transducer match, and are convenient to the base that fin is adjacent to vibration transducer, strengthen the anti-loosening effect of this structure.
Further, above-mentioned two fin 4 shapes are right-angle triangles, and the right-angle side of described fin connects described elastic opening annular pad outer ring.Right-angle side of fin of right-angle triangle connect elastic opening annular pad outer ring, another right-angle side can with stupefied the matching of vibration transducer sexangle base, play the effect that stops vibration transducer to rotate.
This structure Elastic open annular pad in opening both sides with subtended angle to a certain degree, make this pad there is certain elasticity, during installation, the screw rod of magnetic support is screwed in the screw of vibration transducer base after penetrating the inner ring of elastic opening annular pad, along with tightening of screw rod, the subtended angle of elastic opening annular pad opening both sides is driven plain, and pad elastic shrinkage compresses, due to the existence of elastic force, play the effect of locking screw, prevent becoming flexible between magnetic support and vibration transducer; Simultaneously when screw flight is fastening put in place after, by positive and negative two fins on pad, vibration transducer and magnetic support are radially held tightly, play the effect that it can not reverse rotation that makes, two fins are to the centroclinal setting of elastic opening annular pad with slight interior receipts angle, can side direction hold sensor and magnetic support tightly, further guarantee that spiral cannot rotate backward; Thereby guarantee the locking of its screw thread, the signal that magnetic support closely cooperated with being connected more of vibration transducer, vibration transducer gathers is more accurate, has reduced the composition of vibration signal spectrum analysis Middle and low frequency noise, has improved vibration signal spectrum analysis precision.
