TECHNICAL FIELD

[0001] The utility model relates to clothing hanging system technical field, especially chain anti -drop structure and clothing hanging system of a kind of. BACKGROUND

[0002] At present, the clothing hanging thread in the market is widely used with iron chain as line body, and it is matched with sewing work, and the hanging thread of this kind needs to be tensioned to ensure the normal transportation of chain line body. Under the condition of long-term continuous tensioning of iron chain and relatively poor use conditions of clothing factory, the chain line body will inevitably be elongated to a certain extent, which will cause the tensioning end of the hanging thread to be elongated under the action of the tensioning device, thereby increasing the risk of chain derailment and causing shutdown and production stop. The tensioning device is provided to ensure the long-term stable operation of the chain.

[0003] However, due to the internal wear and tear between the chain assemblies, there is a gap inside the chain, which promotes the tensioning of the chain assemblies to both sides under the action of tensioning force, and finally makes the tensioning chain wheel driven by the tensioning sliding rail platform assembly tension the chain to the left side to ensure the stable operation of the chain. As the tensioning end gradually extends to the left, the suspended travel of the chain between the tensioning chain wheel and the main track gradually increases, which gradually reduces the stability of the chain operation and easily causes the chain to derail. Therefore, a chain anti-drop structure and clothing hanging system are proposed to solve the above problems. SUMMARY

[0004] The utility model aims at providing a chain anti-drop structure clothing hanging system, which solves the technical problem that the suspended travel of the chain between the tensioning chain wheel and the main track gradually increases, which gradually reduces the stability of the chain operation and easily causes the chain to derail.

At this time, the telescopic bracket located below the chain supports the push rod assembly upwards, further preventing the chain at the suspended travel position from descending due to the pull of the push rod assembly and causing derailment. Furthermore, when the tensioning slide rail assembly adjusts the position of the tensioning sprocket to maintain the chain tension, the suspension travel between the tensioning sprocket and the main rail gradually increases. The telescopic bracket adjusts its structural length as the suspension travel increases, ensuring that the telescopic bracket can always push the push rod assembly upward when the push rod assembly is in the suspension travel position, without needing to stop the machine for adjustment. This greatly reduces the risk of chain derailment and enhances chain durability, thereby significantly reducing chain derailment failures caused by excessive suspension travel and effectively improving garment production efficiency.

[0033] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0034] As shown in Figure 1 and Figure 2 To achieve the above-mentioned purpose, the present application provides a chain 9 anti-off structure, comprising: a main rail hanger 1 and a tensioning slide rail assembly 2, a main rail 4 and a telescopic bracket 5 arranged on the main rail hanger 1.

[0035] Among them, the tensioning slide rail assembly 2 is slidingly connected to the main rail hanger 1, the bottom of the tensioning slide rail assembly 2 is rotatably connected to the tensioning sprocket 10, the tensioning sprocket 10 is drivingly connected to the chain 9, by adjusting the position of the tensioning slide rail assembly 2 on the main rail hanger 1, thereby adjusting the position of the tensioning sprocket 10 on the main rail hanger 1, so that the chain 9 is always in a tensioning state, and the stable operation of the chain 9 is preliminarily ensured.

[0036] The chain 9 is provided with a push rod assembly 3, the push rod assembly 3 is fixed on the chain 9 and can move synchronously with the chain 9, and the push rod assembly 3 is mainly used for pushing the hanging bracket to move along the transmission rail 11, serving as a power source of the hanging bracket.

[0037] The main rail hanger 1 is provided with a main rail 4, the upper end of the push rod assembly 3 is slidingly connected to the main rail 4, and the main rail 4 is consistent with the running direction of the chain 9. During the movement of the push rod assembly 3 along with the chain 9, the main rail 4 will form a certain top-holding effect on the push rod assembly 3, effectively preventing the chain 9 from descending due to the pulling action of the push rod assembly 3 and causing the chain 9 to derail.

[0038] The lower part of the chain 9 is provided with a telescopic bracket 5, the lower end of the push rod assembly 3 is slidingly connected to the telescopic bracket 5, the telescopic bracket 5 is mainly located below the suspended stroke 8, and is consistent with the running direction of the chain 9. When the push rod assembly 3 moves to the position of the suspended stroke 8, the main rail 4 cannot top-hold the push rod assembly 3, at this time the telescopic bracket 5 arranged below the chain 9 upwardly holds the push rod assembly 3, further preventing the chain 9 at the position of the suspended stroke 8 from descending due to the pulling action of the push rod assembly 3 and causing the chain 9 to derail.

[0039] In use, the chain 9 runs to drive the push rod assembly 3 to move, the push rod assembly 3 moves synchronously with the chain 9, and the push rod assembly 3 drives the hanging bracket to move along the transmission rail 11. When the chain 9 is relaxed and sagged after long-time running, the position of the tensioning slide rail assembly 2 on the main rail hanger 1 is adjusted, so that the position of the tensioning sprocket 10 on the main rail hanger 1 is adjusted, so that the chain 9 is always in a tensioned state. When the tensioning slide rail assembly 2 adjusts the position of the tensioning sprocket 10 to maintain the tensioned state of the chain 9, the suspended stroke 8 between the tensioning sprocket 10 and the main rail gradually increases, and the telescopic bracket 5 adjusts its structural length as the suspended stroke 8 increases, so that when the push rod assembly 3 is at the position of the suspended stroke 8, the telescopic bracket 5 can always upwardly hold the push rod assembly 3, greatly reducing the risk of derailment of the chain 9 and enhancing the durability of the chain 9, thereby greatly reducing the derailment failure of the chain 9 caused by the excessive length of the suspended stroke 8, without the need for shutdown adjustment, effectively improving the efficiency of garment production.

It should be noted that an assembly bracket is arranged below the sprocket, the assembly bracket is rotatably connected to the rotating shaft of the sprocket, the first bracket 501 is fixedly connected to the assembly bracket, and the second bracket 502 is fixedly connected to the bottom of the main rail hanger 1. When the suspended stroke 8 between the tensioning sprocket 10 and the main rail gradually increases, the second bracket 502 will slide relative to the first bracket 501 to increase the length of the second bracket 502 extending out of the first bracket 501, increase the length of the whole telescopic bracket 5, and further ensure that the telescopic bracket 5 can always upwardly hold the push rod assembly 3 when the push rod assembly 3 is at the position of the suspended stroke 8.

[0041] As Figure 4 shown, the lower part of the chain wheel is provided with an assembly frame, the assembly frame is connected with the first fixed support 6, the first fixed support 6 is connected with the second end of the first bracket 501, specifically, the first fixed support 6 is connected with the left end of the first bracket 501, when the suspended stroke 8 between the tensioning chain wheel 10 and the main rail gradually increases, the second bracket 502 moves synchronously with the tensioning chain wheel 10, then the second bracket 502 will slide relative to the first bracket 501 to increase the length of the second bracket 502 extending from the first bracket 501, so as to increase the total length of the telescopic bracket 5.

[0042] It should be noted that the first fixed support 6 is Z-shaped as a whole, the right end of the first fixed support 6 is sunken by a certain height compared with the left end, so as to ensure that the first bracket 501 maintains a proper distance with the chain 9, so that the first bracket 501 just holds the push rod assembly 3 and does not change the original movement track of the push rod assembly 3.

[0043] As Figure 5 shown, the bottom of the main rail hanger 1 is provided with a second fixed support 7, the second fixed support 7 includes: a bracket platform 701, the upper end of the bracket platform 701 is connected with the main rail hanger 1 through bolts, the lower end of the bracket platform 701 is connected with a bracket guide head 702, the bracket guide head 702 is L-shaped as a whole, the bracket guide head 702 is connected with the first end of the second bracket 502, specifically, the bracket guide head 702 is connected with the right end of the second bracket 502.

[0044] In addition, the lower end of the bracket platform 701 is provided with a strip-shaped hole 703, the upper end of the bracket guide head 702 is provided with a bolt hole 704, the bolt passes through the bolt hole 704 and the strip-shaped hole 703, so that the bracket guide head 702 is fixedly connected with the bracket platform 701, by changing the relative position of the bolt hole 704 and the strip-shaped hole 703, the height of the bracket guide head 702 in the vertical direction can be adjusted, so as to adjust the levelness of the second bracket 502, so as to ensure that the telescopic bracket 5 as a whole remains horizontal, so that the telescopic bracket 5 can always stably hold the push rod assembly 3.

[0045] As Figure 1 and Figure 6As shown, the push rod assembly 3 comprises: a mounting frame 301 connected with the chain 9, the mounting frame 301 is fixed on the chain plates on the upper and lower sides of the chain 9, which does not affect the cooperation between the chain plate and the chain pin, so as to ensure that the push rod assembly 3 can move synchronously with the chain 9 as a whole. The upper end of the mounting frame 301 is provided with an upper roller 302 located above the main rail 4, the upper roller 302 is rollably connected with the main rail 4, and the lower end of the mounting frame 301 is provided with a lower roller 303 rollably connected with the telescopic bracket 5. When the push rod assembly 3 moves above the main rail 4, the main rail 4 can support the upper roller 302 to a certain extent, and when the push rod assembly 3 moves above the telescopic bracket 5, the telescopic bracket 5 can support the lower roller 303 to a certain extent. Further, the telescopic bracket 5 and the main rail 4 have a certain overlapping part, that is, when the upper roller 302 rolls on the main rail 4, the lower roller 303 rolls on the telescopic bracket 5 at the same time.

[0046] Further, the lower end of the mounting frame 301 is provided with a push rod 304 located directly above the transmission rail 11. During the synchronous movement of the push rod assembly 3 with the chain 9, the push rod 304 can move along the extension direction of the transmission rail 11 to push the hanging frame to move along the transmission rail 11.

[0047] Among them, the circumferential side of the upper roller 302 is provided with a first annular groove, when the push rod assembly 3 moves above the main rail 4, the first annular groove can cooperate with the main rail 4, the first annular groove is attached to the top surface of the main rail 4, the circumferential side of the lower roller 303 is provided with a second annular groove, when the push rod assembly 3 moves above the main rail 4, the second annular groove can cooperate with the telescopic bracket 5, the second annular groove can be attached to the top surface of the telescopic bracket 5, thereby ensuring that the push rod assembly 3 can stably move along the axial direction of the main rail 4 or the telescopic bracket 5.

[0048] The tensioning slide rail assembly 2 comprises: a guide rail frame 201 arranged at the top of the main rail hanging frame 1, and a sliding seat 204 is further arranged on the guide rail frame 201. The bottom surface of the sliding seat 204 is rotatably connected with the tensioning sprocket 10. By changing the position of the sliding seat 204 on the guide rail frame 201, the position of the tensioning sprocket 10 is changed, and the tensioning degree of the chain 9 is flexibly adjusted. It should be noted that when the position of the sliding seat 204 on the guide rail frame 201 increases the tensioning degree of the chain 9, the free stroke 8 will increase accordingly. The length direction of the guide rail frame 201 is consistent with the length direction of the telescopic bracket 5, so as to ensure that the telescopic bracket 5 can adjust its structural length synchronously with the increase of the free stroke 8.

[0049] As Figure 1 and Figure 7As shown, the top of the main rail hanger 1 is provided with a limiting rack 202, the bottom surface of the limiting rack 202 is arranged with a plurality of first limiting teeth 203, the top surface of the sliding seat 204 is provided with a limiting rod, the limiting rod is perpendicular to the guide rail frame 201 and is arranged on the sliding seat 204, and the top end surface of the limiting rod is provided with a second limiting tooth 205, the second limiting tooth 205 can be connected with the first limiting tooth 203 in a clamping mode, that is, the first limiting tooth 203 and the second limiting tooth 205 can be engaged with each other to limit the axial position of the sliding seat 204 on the guide rail frame 201, so that the tension of the chain 9 can always be kept in a stable state. Further, the first limiting tooth 203 and the second limiting tooth 205 have a certain one-way limiting effect, so that the limiting rod is elastically mounted on the sliding seat 204, during the left movement of the limiting rod along with the sliding seat 204, the second limiting tooth 205 can hold the first limiting tooth 203, so that the limiting rod moves downward, when the first limiting tooth 203 moves to the position of the next first limiting tooth 203, under the elastic force, the second limiting tooth 205 continues to engage with the first limiting tooth 203, so as to lock the position of the sliding seat 204, thereby achieving the adjustment of the tension of the chain 9 without stopping the machine.

[0050] It should be noted that the left side surface of the first limiting tooth 203 is a vertical plane, the right side surface of the first limiting tooth 203 is an inclined plane, the left side surface of the second limiting tooth 205 is an inclined plane, and the right side surface of the second limiting tooth 205 is a vertical plane, so as to ensure that the sliding seat 204 can only move leftward along the axis direction of the guide rail frame 201, so as to increase the tension of the chain 9.

[0051] When the chain 9 is driven to run to drive the push rod assembly 3 to move, the push rod assembly 3 moves synchronously with the chain 9, and the push rod assembly 3 drives the hanging frame to move along the transmission track 11, when the chain 9 is relaxed and sagged after a long time of running, the sliding seat 204 is pushed leftward, the position of the tension sprocket 10 on the guide rail frame 201 is adjusted leftward, so that the chain 9 is always in a tension state, when the position of the tension sprocket 10 on the guide rail frame 201 is adjusted leftward to maintain the tension state of the chain 9, the free stroke 8 between the tension sprocket 10 and the main rail gradually increases, and the telescopic bracket 5 grows in structure length along with the increase of the free stroke 8, so as to ensure that the telescopic bracket 5 always holds the push rod assembly 3 upward when the push rod assembly 3 is at the position of the free stroke 8.

[0052] In addition to the above chain 9 anti-disengagement structure, the utility model also provides a clothes hanging system comprising the chain 9 anti-disengagement structure disclosed in the above embodiment, and the structures of other parts of the clothes hanging system can refer to the prior art, which will not be described herein.

[0053] In summary, the telescopic bracket 5 arranged below the chain 9 upwardly supports the push rod assembly 3 at the position of the suspended stroke 8, preventing the chain 9 at the position of the suspended stroke 8 from being pulled down by the push rod assembly 3 to cause the chain 9 to derail. Moreover, the telescopic bracket 5 adjusts its structural length along with the increase of the suspended stroke 8, ensuring that the telescopic bracket 5 can always upwardly support the push rod assembly 3 at the position of the suspended stroke 8, greatly reducing the risk of the chain 9 derailing and enhancing the durability of the chain 9.
