[0028] In order to better understand the purpose, structure and function of the utility model, the chain structure for a hoist of the utility model is further described in detail below in conjunction with the accompanying drawings.
[0029] like Figure 1-5 As shown, a chain structure for a hoist of the utility model comprises a second chain plate 2, the second chain plate 2 is fixedly connected to a reinforcing frame 8 inside, the reinforcing frame 8 is fixedly connected to a reinforcing bracket 9 inside, the second chain plate 2 is fixedly connected to an outer shell 10 outside, an anti-collision inner plate 11 is arranged inside the outer shell 10, the top and bottom of the outer shell 10 are connected to a closing plate 12 through a rotating shaft, the top of the closing plate 12 is fixedly connected to a magnetic block 13, the magnetic block 13 is magnetically connected to a magnetic groove 14, and the magnetic groove 14 is arranged inside the outer shell 10, through the reinforcing frame 8 and the reinforcing bracket 9 fixedly connected inside the second chain plate 2, and the outer shell 10 outside, an anti-collision inner plate 11 is arranged inside the outer shell 10, when the chain structure is hit outside, the outer shell 10 is used to withstand the impact, and the reinforcing frame 8 and the reinforcing bracket 9 inside the second chain plate 2 are used to support the strength of the mechanism, so that the second chain plate 2 is not easily deformed, and the chain is prevented from being hit during operation or placement, which causes the problem of deformation of the chain plate, and the protection effect is better.
[0030] The second chain plate 2 is fixedly connected to the top of the anti-corrosion layer 15, and the two sides of the anti-corrosion layer 15 are fixedly connected to the L-shaped mounting blocks 16. The bottom of the L-shaped mounting block 16 is provided with an outer shell 10. The anti-corrosion layer 15 provided on the top of the second chain plate 2 can prevent the chain mechanism from rusting when used outdoors or placed for a long time. At the same time, the outer shell 10 also has a certain anti-corrosion effect. Preventing rust can maintain the strength of the chain mechanism, so that the chain mechanism can be used a second time, reducing cost expenditure.
[0031] A first through hole 3 is provided on the surface of the second chain plate 2, and a first through column 5 passes through the first through hole 3. The first through column 5 passes through the first through hole 3 provided on the surface of the second chain plate 2, and the first through column 5 and the second chain plate 2 are combined with each other to form a chain mechanism, which is relatively simple to assemble.
[0032] The top of the first through column 5 is fixedly connected to the top of the second through column 6, and the stud bolt 7 is passed through the inside of the second through column 6. The chain is spliced by passing the stud bolt 7 through the inside of the second through column 6, so that the chain is not easy to fall off. At the same time, the stud bolt 7 can be freely disassembled. Even if a section of the chain plate is damaged and deformed, it can be replaced by removing the stud bolt 7, and the reuse rate is high.
[0033] The surface of the second through-column 6 is movably connected to the first chain plate 1. The surface of the first chain plate 1 is provided with a second through-hole 4. The first chain plate 1 is combined with the second chain plate 2 through the second through-column 6 which passes through the second through-hole 4. By combining different second chain plates 2, a whole chain structure can be spliced together. At the same time, each component can be removed separately. In this way, the chain of the required length can be assembled by oneself according to the needs, and the adaptability is strong.
[0034] The first chain plate 1 is fixedly connected to a reinforcing frame 8 inside, and the surface of the first chain plate 1 is fixedly connected to an outer shell 10. The reinforcing frame 8 inside the first chain plate 1 cooperates with the outer shell 10 on the surface of the first chain plate 1 to support the strength of the first chain plate 1, so that when it is hit, the outer shell can withstand the impact, and the anti-collision effect is better.
[0035] The working principle of the chain structure for a hoist: when using the chain structure for a hoist, it is first necessary to confirm the required chain length and select suitable combination components. After determining various requirements, the first through-hole 3 opened on the surface of the second chain plate 2 is passed through the first through-hole 3 through the first through-hole column 5, and the first through-hole column 5 and the second chain plate 2 are combined to form a chain mechanism. The stud bolts 7 are passed through the inside of the second through-hole column 6 to realize chain splicing, so that the chain is not easy to fall off. At the same time, the stud bolts 7 can be freely disassembled. Even if a section of the chain plate is damaged and deformed, it can be replaced by removing the stud bolts 7, and the reuse rate is high. Subsequently, the second through-hole 4 through-hole through the second through-hole column 6, the first chain plate 1 and the second chain plate 2 are combined. By combining the second chain plates 2 of different sizes, an entire chain structure can be spliced. At the same time, each component can be removed separately, so that the chain of the required length can be assembled according to needs, and the adaptability is strong. After a chain structure is assembled, it can be put into use. The reinforcing frame 8 fixedly connected to the inside of the second chain plate 2 and the supplementary The strong bracket 9 cooperates with the external outer shell 10, and an anti-collision inner plate 11 is provided inside the outer shell 10. When the chain structure is hit outside, the outer shell 10 is used to withstand the impact. The reinforcing frame 8 and the reinforcing bracket 9 inside the second chain plate 2 are used to support the strength of the mechanism, so that the second chain plate 2 is not easily deformed, and the chain is prevented from being hit during operation or placement. The reinforcing frame 8 inside the first chain plate 1 and the outer shell 10 on the surface of the first chain plate 1 cooperate with each other to support the strength of the first chain plate 1, so that when it is hit, the external shell can withstand the impact, avoiding the problem of deformation of the chain plate, and the protection effect is good. The chain structure may rust when it is used outdoors for a long time or is not used for a long time. It needs to be replaced or derusted when used again. The anti-corrosion layer 15 is provided on the top of the second chain plate 2 to prevent the chain mechanism from rusting when it is used outdoors or placed for a long time. At the same time, the outer shell 10 also has a certain anti-corrosion effect. Preventing rust can maintain the strength of the chain mechanism, so that the chain mechanism can be used twice, reducing cost expenditure.
