further, because the limiting block 51 and the gland 4 are in elastic connection, a relative displacement allowance exists between the gland 4 and the limiting block 51 in the horizontal direction; therefore, when the vibration action in the horizontal direction on the pipeline is transmitted to the gland 4, the gland 4 presses the limiting blocks 51 connected to the edge parts, so that the distance between the corresponding limiting blocks 51 is changed, the limiting rods 511 embedded into the positioning grooves 41 on the limiting blocks 51 move, the connected positioning springs 411 deform under stress, the horizontal vibration action between the limiting blocks 51 and the gland 4 is relieved, the horizontal vibration action on the connected suspender 2 and the pipeline is relieved, and the multidirectional vibration reduction operation on the pipeline is realized;
furthermore, because the gland 4 is limited by the limiting blocks 51 uniformly arranged at the edge parts, the abrasion action in the long-term use process can be concentrated to the contact parts between the limiting blocks 51 and the limiting grooves 52, so that the abrasion of the gland 4 is avoided, and the gland 4 can be ensured to be in good condition only by replacing the limiting blocks 51 with serious abrasion in the maintenance process, so that the gland 4 can normally play a role, the service life of the gland 4 is prolonged, and the maintenance cost is reduced.
Embodiment two:
on the basis of the first embodiment, as shown in fig. 2 to 3 and fig. 9 to 12 in the drawings of the specification, the positioning groove 41 is in a laterally extending long strip shape, and the limit lever 511 is in a laterally extending plate-like structure;
