Example

[0030] The first embodiment:

[0031] Attached Figure 5-12 It is an anti-reverse bending transmission chain according to the present invention, comprising a left bending plate 21, a sleeve 22, a roller 23, a right bending plate 24, and a pin 25; the left bending plate 21 and the right bending plate 24 are respectively It is in a transversely stretched Z shape, and two parallel plates are connected together by a connecting plate 216, and the width of the two parallel plates is the same; the two vertical plates on the left bent plate 21 The first plate is close to the outside, and the second plate is close to the inside. The center of the first plate is provided with a first small hole 214, and the center of the second plate is provided with a first large hole 215; Of the two vertical plates on the plate 24, the third plate is close to the outside, and the fourth plate is close to the inside. The center of the third plate is provided with a second small hole 243, and the center of the fourth plate is provided There is a second large hole 244; the left bent plate 21 and the right bent plate 24 are used in pairs, the first and third plates correspond to each other, and the axes of the first small hole 214 and the second small hole 243 are the same A straight line, the second flat plate and the fourth flat plate correspond to each other, and the axes of the first large hole 215 and the second large hole 244 are the same straight line.

[0032] As attached Picture 9 , Picture 10 As shown, a first curved portion 212 is provided at the connection between the first flat plate and the connecting plate 216, and the first curved portion 212 is formed by bending; the first flat plate is opposite to the first curved portion 212. The end is provided with a first anti-bending portion 211, the first anti-bending portion 211 is a straight side, and the lower end of the first anti-bending portion 211 is provided with a round corner centered on the center of the first small hole 214; In an embodiment, the first anti-bending portion 211 is arranged obliquely; the first anti-bending portion 211 is arranged in parallel with the connecting plate 216; the other end of the second flat plate is provided with a semicircle with a first large hole 215 as the center.

[0033] As attached Picture 11 , Picture 12 As shown, the connection between the third flat plate and the connecting plate 216 is provided with a second curved portion 242, and the second curved portion 242 is formed by bending; the third flat plate is opposite to the second curved portion 242. The end is provided with a second anti-bending portion 241, the second anti-bending portion 241 is a straight edge, and the lower end of the second anti-bending portion 241 is provided with a round corner centered on the second small hole 243; In an embodiment, the second anti-bending portion 242 is arranged obliquely; the second anti-bending portion 242 is arranged parallel to the connecting plate 216; the other end of the fourth flat plate is provided with a semicircle with a second large hole 244 as the center; The first anti-bending portion 211 and the second anti-bending portion 242 are arranged in parallel.

[0034] The first bending portion 212 and the second bending portion 242 simultaneously form an angle α with the center of the chain, and the first bending portion 211 and the second bending portion 241 simultaneously form an angle β with the center of the chain. The α is generally It is equal to β. In order to achieve different anti-bending effects, α can also be smaller than β, or α larger than β.

[0035] One end of the sleeve 22 is installed in the first large hole 215 of the left bending plate 21, and the other end is installed in the second large hole 244 of the right bending plate 24; the roller 23 is looped on the sleeve 22, And placed between the second plate of the left bending plate 21 and the fourth plate of the right bending plate 24 to form a chain link 20; the adjacent chain links 20 are connected by a pin 25, and the left bending plate 21 on the rear link The first anti-bending portion 211 on the upper link is in contact with the connecting plate 216 on the left bending plate 21 on the front link, and the third anti-bending portion 241 on the right bending plate 24 on the rear link is in contact with the right The connecting plate 216 on the bent plate 24 is in contact, that is, the pin shaft 25 passes through the first small hole 214 of the left bent plate 21 of the rear link 20, the first large hole 215 of the front link 20, and the sleeve from the outside to the inside. The barrel 22, the second large hole 244 of the front link 20, and the second small hole 243 of the right bending plate 24 of the rear link 20. In this way, the chain links 20 are sequentially connected by the pin 25 to form a reverse bending prevention chain.

[0036] As attached Figure 7 , 8 As shown, when used: the rear pair of chain links 20 can only rotate around the front pair of chain links 20 in a positive direction within a certain angle, but cannot rotate in the reverse direction.

Example

[0037] The second embodiment:

[0038] As attached Figure 13 , 14 As shown, the difference from the left and right bent plates of the first embodiment is that the other end of the second flat plate of the left bent plate is arranged as a third anti-bend portion 213 parallel to the first anti-bend portion 211; The lower end of the third anti-bending portion 213 is provided with a rounded corner centered on the first large hole 215.

[0039] The other end of the fourth flat plate of the right curved plate is set as a fourth anti-bending portion 245 parallel to the second anti-bending portion 241; the lower end of the fourth anti-bending portion 245 is provided with a second large hole 244 as the center Rounded corners.

[0040] During operation, both the first anti-bending portion 211 and the third anti-bending portion 213 on the left bending plate can prevent reverse bending, and the second anti-bending portion 241 and the fourth anti-bending portion 245 on the right bending plate Both can prevent reverse bending; the second embodiment has better reverse bending resistance.

[0041] Due to the application of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0042] 1. The transmission chain can only be bent in one direction, which is suitable for precise transmission occasions.

[0043] 2. Because it can only bend in one direction, it effectively improves the stability of the chain during operation.
