Detailed Description

Referring to fig. 1-5, the utility model provides a closed anti-drop noise-reducing drag chain, which comprises a drag chain body 1, wherein a rubber strip 2 for reducing noise is arranged on the drag chain body 1, a plurality of slotted holes are formed in the rubber strip 2, a first spring 3 is arranged in each slotted hole, a fixed block 4 which is inserted into each slotted hole in a sliding manner and connected with the first spring 3 is arranged on the rubber strip 2, a rubber end block 5 is arranged at one end, far away from the first spring 3, of the fixed block 4, and a space is formed between the rubber end block 5 and the rubber strip 2. The number of the rubber strips 2 is two, and the two rubber strips 2 are respectively positioned at two sides of the top of the drag chain body 1.

In order to reduce the noise that tow chain body 1 produced when the motion, when tow chain body 1 is when the motion, rubber end block 5 on the rubber strip 2 and mesa contact, fixed block 4 removes in the slotted hole under the effort, thereby extrude first spring 3, thereby reduce the shake of tow chain body 1 self when the motion, because rubber strip 2 is rubber materials, can reduce the noise that tow chain body 1 brought in the motion process, the noise that tow chain body 1 brought when the motion can be reduced to this structure, be convenient for people to use.

In this embodiment, a plurality of sponge balls 6 are connected to the side of the rubber end block 5 away from the fixing block 4.

In order to further reduce the brought noise, when the rubber end block 5 is in contact with the table top, the rubber end block can be in contact with the table top in advance through the sponge ball 6, so that the noise generated when the drag chain body 1 moves is further reduced.

In a further embodiment, an elastic limit stop 7 is mounted on the rubber end block 5 on the side close to the rubber strip 2. An opening is formed in the rubber end block 5, the elastic limiting piece 7 comprises a second spring 71 and a fixed cylinder 72, the second spring 71 is installed in the opening, the fixed cylinder 72 is inserted in the opening and connected with the second spring 71, and a rubber ball 73 is installed at one end, close to the rubber strip 2, of the fixed cylinder 72.

In order to facilitate limiting the moving position of the fixed block 4 and reduce noise, when the tow chain body 1 moves and the fixed block 4 is stressed to move in the groove hole, the rubber end block 5 approaches to the rubber strip 2 and can be contacted with the rubber strip 2 through the rubber ball 73, meanwhile, the fixed cylinder 72 moves in the open hole formed in the rubber end block 5 to extrude the second spring 71, and under the reaction force of the second spring 71, the fixed cylinder 72 plays a role in jacking the rubber strip 2 to limit the fixed block 4 and reduce noise generated when the rubber end block 5 is contacted with the rubber strip 2.
