[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-Figure 7 As shown, the flexible connection structure for installing a drag chain of the utility model includes a drag chain mounting frame 10 and a connecting plate 20, and two buffer systems are arranged between the drag chain mounting frame 10 and the connecting plate 20; the buffer system includes a support column 30, the tow cable mounting frame 10 is connected and fixed to one end of the support column 30 by a first bolt 31, and the connecting plate 20 is sleeved on the other end of the support column 30, and the connecting plate 20 can move along the axial direction of the support column 30; a spring 40 is sleeved on the outer side of the support column 30, and the two ends of the spring 40 are respectively in conflict with the drag chain mounting frame 10 and the connecting plate 20; the other end of the support column 30 is connected to a second bolt 32, and a limiting ring 50 is fixed on the second bolt 32, and the connecting plate 20 is located between the limiting ring 33 and the spring 40.

[0023] In this embodiment, the support column 30 may be cylindrical, and a connecting through hole 33 is provided inside the support column 30 along the axial direction. The connecting through hole 33 is a threaded through hole, and the first bolt 31 and the second bolt 32 are connected in the connecting through hole 33. The length of the connecting through hole 33 (i.e., the length of the support column 30) is greater than the sum of the bolt body lengths of the first bolt 31 and the second bolt 32, which can ensure that the first bolt 31 and the second bolt 32 are effectively connected in the connecting through hole.

[0024] The tow chain mounting frame 10 is provided with a first through hole 11 , and the first bolt 31 passes through the first through hole 11 and is connected in the connecting through hole 33 , so that the tow chain mounting frame 10 can be connected and fixed to the supporting column 30 .

[0025] The connecting plate 20 is provided with a second through hole 21, and the diameter of the second through hole 21 is larger than the outer diameter of the support column 30. The connecting plate 20 is sleeved on the support column 30 through the second through hole 21, and the connecting plate 20 can move along the axial direction of the support column 20.

[0026] Preferably, the inner wall of the second perforation 21 is provided with a lubricating layer (not shown in the figure), which can play a lubricating role, so that the connecting plate 20 can move smoothly along the axial direction of the support column 30 to avoid jamming, thereby enabling the buffer system to play an effective buffering role.

[0027] Alternatively, the outer wall of the support column 30 is provided with a lubricating layer (not shown in the figure), which can play a lubricating role, so that the connecting plate 20 can move smoothly along the axial direction of the support column 30 to avoid jamming, thereby enabling the buffer system to play an effective buffering role.

[0028] The limiting ring 50 is provided with a fixing through hole 51 , and the second bolt 32 passes through the fixing through hole 51 and is connected in the connecting through hole 33 .

[0029] The second bolt 32 is fixed in the fixing through hole 51, so that the limiting ring 50 and the second bolt 31 can be fixed. The fixing method of the second bolt 32 in the fixing through hole 51 can be a common fixing connection method in the technical field, such as a threaded fixing connection, which is not specifically limited here.

[0030] The projection of the limiting ring 50 can be circular, and the diameter of the limiting ring 50 is larger than the aperture of the second through hole 21 on the connecting plate 20, so that it can play an effective limiting role, so that the connecting plate 20 can effectively move axially along the support column 30, effectively limiting the connecting plate 20 from detaching from the support column 30.

[0031] In other preferred embodiments, the projection of the limiting ring 50 can also be a rectangle, and the side length of the rectangle is greater than the aperture of the second perforation 21, so that it can play an effective limiting role, allowing the connecting plate 20 to effectively move axially along the support column 30, effectively limiting the connecting plate 20 from detaching from the support column 30.

[0032] The material of the limiting ring 50 can be steel, and the thickness of the limiting ring 50 can be 1-4 mm, so that the limiting ring 50 has sufficient strength to ensure that the limiting ring 50 plays an effective limiting role and effectively limits the connection plate 20 from separating from the support column 30.

[0033] The spring 40 can be a cylindrical spring coil commonly used in the technical field. The inner diameter of the spring 40 is larger than the aperture of the second through hole 21 on the connecting plate 20, so that the spring 40 can be effectively protruded from the connecting plate 20, thereby allowing the connecting plate 20 to effectively resist the spring 40 during movement.

[0034] like Figure 7As shown, the connecting plate 20 is used to connect the drag chain 60, one end of the drag chain 60 is the drag chain moving end 61, and the other end is the drag chain fixed end 62. The drag chain fixed end 62 is mounted and fixed on a base (not shown in the figure), and the drag chain moving end 61 is connected to the drag chain mounting frame 10 through the connecting plate 20 and two buffer systems, and the drag chain mounting frame 10 is mounted and fixed on the transmission system. Through the transmission system, the drag chain mounting frame 10 and the drag chain moving end 61 can be towed to move, and the two buffer systems can alleviate the rigid impact of the drag chain moving end 61 on the transmission system, reduce the reaction force of the drag chain moving end 61 on the transmission system, and thus improve the control accuracy of the transmission system.

[0035] The moving end 61 of the drag chain is fixed on the connecting plate 20 , and the fixing method may be a common fixing method in the technical field, and no specific limitation is made here.

[0036] Since the moving end 61 of the drag chain is fixed on the connecting plate 20, the moving end 61 of the drag chain and the connecting plate 20 can move axially along the support column 30; during the movement of the moving end 61 of the drag chain and the connecting plate 20, the spring 40 mounted on the support column 30 can be compressed, and under the elastic force of the spring 40, the reaction force of the moving end 61 of the drag chain can be buffered and absorbed, thereby reducing the impact force of the moving end 61 of the drag chain on the transmission system.

[0037] Two buffer systems are provided between the drag chain mounting frame 10 and the connecting plate 20, so that the connecting plate 20 cannot rotate around the supporting column 30, thereby enabling the connecting plate 20 to play an effective connecting role and preventing the drag chain moving end 61 from rotating.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
