[0004] The technical solution of the utility model is as follows:

[0005] An inner link of an easily assembled and disassembled conveyor chain comprises inner link plates distributed front and rear, a sleeve and a roller being arranged between the front and rear inner link plates, the sleeve passing through the inner center position of the roller, and characterized in that: the front and rear sides of the roller are provided with mounting isolation bosses at the center position cooperating with the inner link plates, a movable safety lubrication groove is formed between the outer side of the mounting isolation bosses and the inner link plates, a fastening combination key is arranged at the outer side end surface position of the connection position between the inner link plate and the sleeve, the fastening combination key is connected with the matching grooves arranged on the inner link plate and the sleeve by a press-fit combination, and the outer side end surface of the sleeve is on the same plane as the outer side end surface of the inner link plate.

[0006] Furthermore, the outer end surfaces of the fastening combination keys are on the same plane.

[0007] Furthermore, the cross-section of the fastening combination key is a rectangular structure.

[0008] Furthermore, the thickness of the fastening combination key is the same as the thickness of the inner link plate.

[0009] Beneficial effects of the utility model:

[0010] The utility model adopts a brand-new structural design, and the inner chain link as a whole is fastened together by a separate fastening key so that the various parts can be fastened together to form a separate chain link structure. The disassembly and assembly operation during later assembly or maintenance is more convenient, and the inner chain link as a whole can be replaced or maintained after the pin shaft of the chain is removed. The disassembly and assembly during maintenance is more convenient, and there is no need to carry out the matching installation of the separate parts at the maintenance site, thus ensuring the matching accuracy between the inner chain link parts, thereby effectively improving the overall load-bearing capacity of the chain, and the stability during operation is more reliable.

[0013] In the figure: 1. inner link plate, 2. sleeve, 3. roller, 4. fastening combination key. DETAILED DESCRIPTION

[0014] like Figure 1 and Figure 2 As shown, an inner link of an easily assembled and disassembled conveyor chain comprises an inner link plate 1 distributed front and back, a sleeve 2 and a roller 3 are arranged between the front and rear inner link plates 1, the sleeve 2 passes through the inner center position of the roller 3, and the front and rear sides of the roller 3 are provided with a mounting isolation boss column at the center position cooperating with the inner link plate 1, and a movable safety lubrication groove is formed between the outer side of the mounting isolation boss column and the inner link plate 1, so that the lubricating liquid can be more smoothly and evenly matched in the active position during later use, and the space of the active position is also larger. A fastening combination key 4 is arranged at the outer end surface position of the connection position between the inner link plate 1 and the sleeve 2, and the fastening combination key 4 is connected with the matching groove arranged on the inner link plate 1 and the sleeve 2 by a press-fit combination method, so that the overall components can become an assembly unit, which is more convenient and quick during later maintenance or assembly. The outer end surface of the sleeve 2 is on the same plane as the outer end surface of the inner link plate 1, ensuring the flatness and structural stability of the overall structure. It adopts an integrated and combined structural design, and the inner chain links as a whole are fastened together through separate fastening keys to form a separate chain link structure. The disassembly and assembly during later assembly or maintenance is more convenient. The inner chain links as a whole can be replaced or maintained after the chain pin is removed. The disassembly and assembly during maintenance is more convenient, and there is no need to carry out matching installation of separate parts at the maintenance site, thus ensuring the matching accuracy between the inner chain link parts, thereby effectively improving the overall load-bearing capacity of the chain, and making the stability during operation more reliable.

[0015] Preferably, the outer end faces of the fastening combination keys 4 are on the same plane, so that the outer position has better flatness and occupies less space.

[0016] Preferably, the cross-section of the fastening combination key 4 is a rectangular structure, which has lower production costs and is more convenient to process.

[0017] Preferably, the thickness of the fastening combination key 4 is the same as the thickness of the inner link plate 1, so that the matching space of the combination position is larger and the strength of the fastening combination can be optimized.

[0018] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
