Description

Technical Field

[0001] This utility model relates to the field of chain technology, and in particular to a chain that is easy to combine and transmit. Background Technology

[0002] Chains consist of components such as outer chain plates, inner chain plates, and pins. The pins pass through both the inner and outer chain plates. They are generally metal links or rings and are mostly used for mechanical transmission, traction, and as chain-like objects used to obstruct traffic (such as in streets and at the entrances of rivers or harbors). They are also used for mechanical transmission.

[0003] When the existing chain is in operation, the outer and inner chain plates are misaligned in the radial direction of the pin. After long-term use, the wear of the inner and outer chain plates is asymmetrical, which shortens the chain life, increases the replacement cost, and makes the chain prone to rust after long-term use. If lubricating oil is not applied in time, it will easily cause chain damage. Utility Model Content

[0004] This utility model addresses the problems of difficult assembly and disassembly of chains and their susceptibility to rust. The technical problem this utility model aims to solve is to provide a chain that is easy to assemble and transmit.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a chain that is easy to combine and transmit, characterized in that it includes a first chain unit and a second chain unit, the first chain unit and the second chain unit are rotatably connected together by a pin, the first chain unit is provided with a first step and a second step, the second chain unit is provided with a groove and a convex edge, the first chain unit and the second chain unit are arranged alternately, at this time the first step is inserted into the groove, and the second step and the convex edge abut against each other.

[0006] A further preferred embodiment of this utility model is: the first chain unit is provided with an outer chain plate, the number of the outer chain plates is two, and a first connecting plate is detachably provided between the two outer chain plates.

[0007] A further preferred embodiment of this utility model is: the outer chain plate is provided with an insert block, and the first connecting plate is provided with a slot for inserting the insert block.

[0008] A further preferred embodiment of this utility model is that the insert block is inserted into the slot by an interference fit.

[0009] A further preferred embodiment of this utility model is: the second chain unit is provided with an inner chain plate, the number of which is two, and a second connecting plate is fixedly provided between the two inner chain plates.

[0010] A further preferred embodiment of this utility model is: the inner chain plate is provided with an oil inlet for adding lubricating oil and an oil storage chamber for storing lubricating oil.

[0011] A further preferred embodiment of this utility model is that a thin film for sealing the lubricating oil is provided on the surface of the oil storage cavity.

[0012] A further preferred embodiment of this utility model is that the groove is provided with an oil outlet for discharging lubricating oil.

[0013] Compared with the prior art, the present invention has the following advantages: the outer chain plate on the chain is provided with a first step and a second step, and the inner chain plate is provided with a groove and a convex edge. When the first step is inserted into the groove, the second step and the convex edge abut against each other to limit the running position of the inner chain plate and the outer chain plate, ensuring that the running of the outer chain plate and the inner chain plate will not be offset in the radial direction of the pin. In addition, the oil tank in the inner chain plate is provided with lubricating oil. As the inner chain plate runs, the lubricating oil in the oil tank is evenly distributed to the inner chain plate to lubricate the outer chain plate and the inner chain plate, thereby extending the service life of the outer chain plate and the inner chain plate.

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] This embodiment mainly describes a chain that is easy to combine and transport, as detailed below:

[0025] like Figure 1 As shown, a chain that is easy to combine and transmit is mainly composed of several first chain units 13 and several second chain units 14. The first chain units 13 and the second chain units 14 are rotatably connected by pins 2, which ensures that the first chain units 13 and the second chain units 14 can rotate relatively flexibly, thereby ensuring that the chain can operate smoothly under different working environments and transmission requirements.

[0026] like Figure 2 , Figure 3 As shown, the first chain unit 13 is provided with an outer chain plate 8. Specifically, there are two outer chain plates 8 on one first chain unit 13, and the two outer chain plates 8 are arranged symmetrically.

[0027] The two outer link plates 8 are detachably connected together by the first connecting plate 1. Specifically, the outer link plate 8 is provided with a plug 7, and the corresponding first connecting plate 1 is provided with a slot 6 for the plug 7 to be inserted. When the outer link plate 8 and the first connecting plate 1 are installed, the plug 7 is inserted into the slot 6 by interference fit, so that the two outer link plates 8 and the first connecting plate 1 are firmly connected.

[0028] The second chain unit 14 is provided with an inner chain plate 9. Specifically, there are two inner chain plates 9 on one second chain unit 14, and the two inner chain plates 9 are arranged symmetrically.

[0029] A second connecting plate 3 is fixedly installed between the two inner chain plates 9 to ensure the relative positional stability between the inner chain plates 9.

[0030] The chain is usually driven by a sprocket. The first chain unit 13 and the second chain unit 14 are arranged alternately, so that there is a gap between the first connecting plate 1 and the second connecting plate 3 for the sprocket to insert into. The sprocket rotates in the gap, driving the first chain unit 13 and the second chain unit 14 to run synchronously.

[0031] The outer chain plate 8 and the inner chain plate 9 are rotatably connected together. Specifically, the outer chain plate 8 is provided with a first step 4 and a second step 5, and the inner chain plate 9 is provided with a groove 10 and a protrusion 11 corresponding to the first step 4 and the second step 5. When the outer chain plate 8 and the inner chain plate 9 are assembled and running, the groove 10 is inserted into the first step 4 on the outer chain plate 8, and the protrusion 11 abuts against the second step 5 on the outer chain plate 8 to limit the running position of the inner chain plate 9 and the outer chain plate 8, ensuring that the running of the outer chain plate 8 and the inner chain plate 9 will not be offset in the radial direction of the pin 2, so that the connection between the first chain unit 13 and the second chain unit 14 is more stable, and the stability of the overall chain structure is effectively guaranteed.

[0032] like Figure 4 As shown, the inner chain plate 9 has an oil inlet 12 on its surface and an oil storage chamber 13 inside. The user adds lubricating oil into the oil storage chamber 13 through the oil inlet 12. The surface of the oil storage chamber 13 is covered with a thin film 14 that seals the lubricating oil. The film 14 is made of rubber and has an opening at the oil inlet 12. When the user adds lubricating oil through the oil inlet 12, the film 14 is recessed into the oil storage chamber 13 to facilitate the addition of lubricating oil. After the user finishes adding the lubricating oil, the film 14 recovers under its own elasticity, sealing the oil inlet 12 and preventing oil leakage during chain operation.

[0033] The inner chain plate 9 has two oil outlets 15 on the surface of its groove 10. During chain operation, the lubricating oil in the oil storage chamber 13 is discharged from the oil outlets 15 to lubricate the friction between the outer chain plate 8 and the inner chain plate 9, thereby increasing the service life of the outer chain plate 8 and the inner chain plate 9.

[0034] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use.
