Detailed Implementation

[0024] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] The following embodiments can be understood as explaining a partial structure of the present invention individually, or as explaining a larger structure of the present invention through a combination of multiple embodiments.

[0026] Example 1

[0027] A chain for conveying U-shaped plates, such as Figures 4-8 As shown, the device includes a conveyor chain body, on which several inverted U-shaped plates 6 are arranged at equal intervals. The top of the U-shaped plates 6 is provided with an impact-resistant structure. The top of the U-shaped plates 6 is also connected to a rubber block B8 through a vulcanization process. The rubber block B8 is integrated with the impact-resistant structure.

[0028] like Figures 4-8 As shown, the impact-resistant structure is a protruding structure of regular or irregular shape, and the protruding structure extends upward along the top of the U-shaped plate 6.

[0029] In this embodiment, the specific structure of the conveying chain body can adopt the chain structure of the existing conveying chain, and the improvement is that the top end of the U-shaped attachment plate 6 is provided with an impact-resistant structure. The shape of the impact-resistant structure can be various, such as tubular, columnar, irregular shape, which can improve the gripping force of the rubber block B and the lateral impact resistance of the chain. When the chain is running and encounters a lateral impact force, it can ensure the stability of the structure of the rubber block B and the safety of the transported goods. Among them, the rubber block B plays a role in supporting the goods, and the connection area between it and the impact-resistant structure is large, and has a mutual lateral support effect, so that the rubber block B has a rigid skeleton inside, and the structural strength is higher.

[0030] Embodiment 2

[0031] As shown in Figures 4-8 , the convex structure is a tubular structure 42 integrally formed with the top end of the U-shaped attachment plate 6. The tubular structure 42 extends vertically upward. The rubber block B8 is connected with the outer wall of the tubular structure or with the outer wall and the inner hole of the tubular structure.

[0032] In this embodiment, the tubular structure is selected as the impact-resistant structure. The preparation process of the tubular structure is simple, only the U-shaped attachment plate top hole is turned upward, and then the manufacturing cost can be reduced. Of course, the U-shaped attachment plate can be integrally formed by mold pouring.

Two first connecting holes 61 are arranged on the connecting parts. The top end of the two connecting parts is integrally connected with a bearing part (i.e. the top wall of the U-shaped attachment plate). The junction of the connecting part and the bearing part is chamfered to avoid stress concentration.

[0037] As shown in Figures 4-8 , the conveying chain body is a single-row or double-row roller chain structure. The single-row roller chain includes inner chain plates B1, outer chain plates B2, pin shafts B5, sleeves B4, and rollers B3. The assembly form is a commonly used structure, that is, two inner chain plates B are assembled with sleeves B and rollers B to form an inner chain link, two outer chain plates B are assembled with pin shafts B to form an outer chain link, and the inner and outer chain links are connected by pin shafts B (the structure not described is solved by the existing scheme).

[0038] As shown in Figures 4-8As shown, the double-row roller chain is composed of two single-row roller chains arranged side by side and two middle chain plates B7 added in the middle of the two single-row roller chains, the middle chain plate B is arranged opposite to the outer chain plate B on both sides and is in clearance fit with the corresponding pin shaft B, the inner chain plate B, the outer chain plate B and the middle chain plate B are arc structures at both ends and are straight line structures connected between the top or bottom of the two arc structures, the improvement of the structure of the inner chain plate B, the outer chain plate B and the middle chain plate B can effectively improve the tensile capacity of the chain and avoid the tearing phenomenon of the inner chain plate B, the outer chain plate B and the middle chain plate B due to excessive stress (the assembly structure of the double-row roller chain is prior art, and the content not mentioned is solved by the prior scheme).

[0039] As shown in Figures 4-8 The connecting portions on both sides of the U-shaped attachment plate 6 are respectively arranged inside the outer chain plate B arranged opposite at the left and right ends of the single-row or double-row roller chain, the outer chain plate B is provided with two second connecting holes, the first connecting hole and the second connecting hole are one-to-one opposite and are respectively in clearance fit and interference fit with the pin shaft B, the pin shaft B passes through the second connecting hole, the first connecting hole, the third connecting hole on the inner chain plate B and the fourth connecting hole on the middle chain plate B from outside to inside, and the pin shaft B is in clearance fit with the third connecting hole.

[0040] Example 5

[0041] As shown in Figures 4-8 The rubber block B8 is a quadrangular frustum structure, which has better stability and is convenient for supporting goods.
