Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): referring to fig. 2 and 3, for the utility model discloses an electric block with anti-sway device, including electric block body 1, electric block body 1 includes shell 11 and chain 12 (see fig. 4). The tail end of the chain 12 is provided with a hook body 13 (see fig. 5), and if the chain 12 is operated outdoors and meets the strong wind weather, the chain is easy to shake, so that the transported goods are easy to fall off from the hook body 13. The sleeve 2 is sleeved outside the chain 12, and the sleeve 2 can prevent the chain 12 from shaking, so that the possibility of damage to goods can be reduced.

As shown in fig. 2, the casing 2 includes a fixed casing 21, the fixed casing 21 is sequentially sleeved with a plurality of connection casings 22 with gradually increasing inner diameters in a direction away from the housing 11, the fixed casing 21 is communicated with the connection casings 22, and the chain 12 passes through the fixed casing 21 and the connection casings 22.

As shown in fig. 6 and 7, the fixing sleeve 21 and the connecting sleeve 22 are provided with an anti-drop mechanism for preventing dropping between the fixing sleeve 21 and the connecting sleeve 22 and between the connecting sleeve 22, the anti-drop mechanism includes an annular bearing protrusion 3, the bearing protrusion 3 is respectively fixedly connected to one side of the fixing sleeve 21 and one side of the connecting sleeve 22 far away from the chain 12, the end of the connecting sleeve 22 close to the shell 11 extends to a direction close to the chain 12 to form an annular boss 221, and the fixing sleeve 21, the connecting sleeve 22 and the connecting sleeve 22 can not drop through clamping of the bearing protrusion 3 and the boss 221.

The supporting lug 3 is provided with a buffer mechanism for reducing acting force between the supporting lug 3 and the boss 221, the buffer mechanism comprises a plurality of buffer springs 4 fixedly connected with the supporting lug 3, and one ends of the buffer springs 4 far away from the supporting lug 3 are fixedly connected with annular buffer blocks 41. When the connection sleeve 22 slides in a direction away from the housing 11, the boss 221 contacts the buffer block 41 and continues downward, so that the buffer spring 4 is compressed, and the force between the boss 221 and the receiving boss 3 is reduced.

As shown in fig. 5, a circular transverse plate 121 is fixedly connected to the end of the chain 12, the transverse plate 121 is fixedly connected to the connecting sleeve 22 away from the housing 11, and the diameter of the transverse plate 121 is smaller than the inner diameter of the fixing sleeve 21. The transverse plate 121 is detachably connected with the hook body 13 away from the housing 11, the hook body 13 includes a suspension rod 131 and a hook 132, and the volume of the hook 132 is larger than the inner diameter of the connection sleeve 22. A rectangular mounting block 1311 is fixedly connected to an end of the suspension rod 131 away from the hook 132. One side of the transverse plate 121 far away from the chain 12 is fixedly connected with a rectangular mounting piece 1211, a bolt passes through the mounting block 1311 and the mounting piece 1211, two ends of the bolt are in threaded connection with nuts, and the nut can fix the hook body 13 on the transverse plate 121 when being tightened.

When needs transport the goods, behind the fixed goods on hook 132, chain 12 drives the goods, makes the goods upwards promote, and it is ascending along with chain 12 drive goods, when hook 132 contacted terminal sleeve pipe 2, because hook 132 volume is greater than the adapter sleeve 22 internal diameter, hook 132 drove adapter sleeve 22 and upwards moved, when hook 132 contacted adapter sleeve 21, the goods rose to the highest point.

When the goods are transported to the highest place and taken off, the connecting sleeve 22 slides downwards due to the action of gravity, and the boss 221 contacts the buffer block 41 and continues to move downwards, the buffer spring 4 is compressed, so that the acting force between the boss 221 and the bearing lug 3 is reduced.

As shown in fig. 3, end blocks 211 are fixedly connected to both sides of one end of the fixing sleeve 21 close to the housing 11, a fixing block 111 is fixedly connected to one side of the housing 11 far from the chain 12 of the end block 211, and the end blocks 211 are bolted to the fixing block 111, so that the fixing sleeve 21 is fixed to the housing 11.

The implementation principle of the embodiment is as follows: when needs transport the goods, behind the fixed goods on hook 132, chain 12 drives the goods, makes the goods upwards promote, and it is ascending along with chain 12 drive goods, when hook 132 contacted terminal sleeve pipe 2, because hook 132 volume is greater than the adapter sleeve 22 internal diameter, hook 132 drove adapter sleeve 22 and upwards moved, when hook 132 contacted adapter sleeve 21, the goods rose to the highest point.

When the sleeve 2 needs to be removed, the hook body 13 is first removed from the cross plate 121, and the fixing sleeve 21 is then removed from the housing 11, so that the sleeve 2 can be removed from the housing 11.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
