The lower edge of the straight section is provided with a limit notch 553 extending along the horizontal direction. The upper end of the connecting plate is provided with an upper limiting clamping groove 541, and the lower end is provided with a lower limiting clamping groove 542. The upper end of the connecting plate is connected to the end part of the crosspiece 56 through an upper connecting bolt, and the upper limiting clamping groove is sleeved on the end part of the crosspiece. The lower end of the connecting plate is connected to the straight section through a lower connecting bolt, and the lower side wall of the lower limiting clamping groove penetrates through the limiting notch. The lower limiting clamping groove is sleeved on the straight section. The crosspiece is located the center post top.

The central column 4 is a cylinder. The upper end face of the central column is provided with a spring mounting hole 42. A vibration damping spring 43 which extends and contracts in the vertical direction is provided in the spring mounting hole. A positioning rod 44 is inserted into the damping spring. The positioning rod is provided with a pressure plate 45 which is placed on the upper end of the slow vibration spring. The crosspiece is threadedly connected with a pre-tightening bolt 46 of a cushioning spring which abuts against the pressure plate. The upper end of the damping spring is supported directly or indirectly (in this embodiment, directly) on the crosspiece.

The second embodiment is different from the first embodiment in that:

referring to fig. 3, 4 and 5, a compression plate 6, which is connected in a sliding and sealing manner in the spring mounting hole 42, is fixed to the positioning rod 44. The compression plate isolates a sealed grease reservoir 421 and a backup grease reservoir bowl 423 above the grease reservoir within the spring mounting hole. A damping spring 43 is located within the sealed grease reservoir and is supported on the lower surface of the compression plate. An oil outlet window 426 which penetrates through the sealed grease storage cavity is arranged on the side wall of the spring mounting hole. A sealing plug 424 and a window closing spring 425 for driving the sealing plug to move towards the sealed grease storage chamber to close the oil outlet window are arranged in the oil outlet window. The compression plate is provided with a compression plate part one-way valve 61 which opens towards the sealed grease storage cavity.

This embodiment also includes a grease replenishment mechanism for adding grease to the backup grease reservoir bowl. The grease supplementing mechanism comprises a nozzle 3, a grease gun 7 and a control mechanism 8.

The oil nipple 3 includes a nipple housing 31 and an outer rotor motor 32. A grease passage 311 is provided in the nozzle housing. The grease passage forms a grease outlet 312 through the underside of the nipple housing. The other end of the grease channel is provided with a grease inlet 313. The outer rotor motor includes an inner stator 321 and an outer rotor 322. The oil nozzle shell is connected to the inner stator. The outer rotor is connected with an outlet plug 34 for closing the grease outlet through a connecting elastic sheet 33. When the outlet plug is aligned with the lubricating grease outlet, the outlet plug is abutted against the lubricating grease outlet under the action of the elastic force of the connecting elastic sheet so as to seal the lubricating grease outlet. The outlet plug is a spherical hollow structure. The inner tank of the outlet plug is filled with lubricating oil. The upper end of the outlet plug is provided with a plurality of volatilization through holes 341 positioned inside the air outlet when the outlet plug is sealed in the grease outlet and a lubrication hole sealing plate 342 made of ferromagnetic iron for covering the volatilization through holes. The lubrication hole sealing plate is provided with a sliding column 343 arranged on the outlet plug in a penetrating way. The outlet plug is internally provided with a cover closing spring 344 which is connected with the sliding column and used for driving the lubrication hole sealing plate to cover the volatilization through hole. The interior of the lubricating grease channel is provided with a permanent magnet 35 which adsorbs the lubricating hole sealing plate to open the lubricating hole sealing plate.

When the lubricating grease channel outlet needs to be opened, the connecting elastic sheet is driven to rotate through the outer rotor motor, and therefore the outlet plug and the lubricating grease channel outlet are staggered. The lubricating hole closing plate covers the volatilization through hole under the action of the closing spring of the closing plate, so that the lubricating oil cannot volatilize. When the lubricating grease channel outlet needs to be closed, the outer rotor motor drives the connecting elastic sheet to rotate, so that the outlet plug is aligned with the lubricating grease channel outlet, and the outlet plug covers the lubricating grease channel outlet under the elastic action of the connecting elastic sheet. The permanent magnet attracts the lubrication hole shrouding and overcomes the elasticity of shrouding closing spring for the lubrication hole shrouding loses the closing cap effect to the through-hole that volatilizees, and lubricating oil volatilizees and plays and prevents that remaining lubricating grease in the lubricating grease outlet from producing the effect that the solidification blockked up.

The grease outlet is located above the backup grease storage bowl 423.

The grease gun 7 includes a barrel 71 and a push plate 72 slidably and sealingly attached within the barrel. The push plate divides the barrel into an oil chamber 711 and an air chamber 712. The oil chamber communicates with the inlet end of the grease passage, i.e. grease inlet 313. The air chamber is provided with an inlet electric valve 73. When in use, lubricating grease is filled in the oil cavity.

The control mechanism 8 includes a control unit 81, a vertical rack 82 attached to the rung, a gear 83 meshed with the vertical rack, and a detection unit 84 detecting the number of rotations of the gear. The gear is connected to the central column through a one-way bearing. The detection unit 84 includes a sensing switch 841 and a stopper 842 provided on the gear. When the gear rotates to the position that the stop block and the inductive switch are close to the nearest distance, the inductive switch induces and inputs a signal to the control unit, and the induction disclosure indicates that the gear rotates for one circle when the stop block is induced once. The control unit is electrically connected with the induction switch, the outer rotor motor and the inlet electric valve.

When the grease storage bowl is used, when the number of turns of the gear detected by the detection unit reaches the integral multiple of the set number of turns, the control unit enables the air inlet electric valve and the grease nipple to be opened for a set time, so that lubricating grease in the grease cavity is added into the grease storage bowl through the grease nipple. For example, if the set number of turns is 10, the oil nozzle and the entering electric valve are closed after the oil nozzle and the entering electric valve are opened for a set time length when the gear rotates 10 turns, the oil nozzle and the entering electric valve are closed after the oil nozzle and the entering electric valve are opened for a set time length when the gear rotates 20 turns, the oil nozzle and the entering electric valve are closed after the oil nozzle and the entering electric valve are opened for a set time length when the gear rotates 30.
