Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of conveyor chains, in particular to a detachable locking conveyor chain. Background Art
[0002] Chains are commonly used and important products in conveying and rotating equipment. During production, the existing chain products are press-fitted between chain links with pins, and the ends are connected with stops. The tightness of the chain links in the thickness direction cannot be adjusted, and it is difficult to disassemble and assemble later, and separate tools are required to complete it. During long-term use, the fastening position of the pin is prone to loosening, resulting in the inability to ensure smooth operation. Utility Model Content
[0003] The utility model aims to provide a detachable locking conveyor chain, which is combined with a nut and a cotter pin by arranging a threaded pin shaft when tightening. The nut can be tightened with the threaded pin shaft by threaded cooperation, and the tightening position can be adjusted. When looseness occurs during later use, the tightening adjustment can be carried out in time. There is no need to disassemble the entire chain, which is more convenient for maintenance. The firmness of the connection position is more reliable. It has an anti-loosening effect during long-term use, can ensure the stability of the chain operation, and extend the overall service life of the chain.
[0004] The technical solution of the utility model is as follows:
[0005] A detachable locking conveyor chain, characterized in that it includes a plurality of inner chain links and outer chain links, the inner chain links include inner chain plates, sleeves, and rollers, the inner chain plates are respectively mounted on both ends of the sleeve, the rollers are sleeved on the sleeves and are located between the two inner chain plates; the outer chain links include outer chain plates, threaded pins, locking nuts and cotter pins, the threaded pins pass through the sleeves on one chain link and are fixed between the outer chain plates of the next chain link, the threaded pin heads are provided with threads and fastening holes, and the locking nuts cooperate with the threads on the threaded pins.
[0006] Furthermore, an integral fastening and clamping fitting groove is provided at an outer position of the other end of the threaded pin head.
[0007] Beneficial effects of the utility model:
[0008] The utility model discloses a chain is connected with the chain by the screw thread, and the chain is connected with the chain by the screw thread, so that the chain is convenient to maintain and can be used for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] like Figure 1 and Figure 2 As shown, a detachable locking conveyor chain includes a plurality of inner chain links and outer chain links. The inner chain links include inner chain plates 1, sleeves 2, and rollers 3. The inner chain plates 1 are respectively mounted on both ends of the sleeve 2. The rollers 3 are sleeved on the sleeve 2 and are located between the two inner chain plates 1. The outer chain links include outer chain plates 4, threaded pins 5, locking nuts 6, and cotter pins 7. The threaded pins 5 pass through the sleeves 2 on one chain link and are fixed between the outer chain plates 4 of the next chain link. The threaded pins 5 are provided with threads and fastening holes on their heads. The locking nuts 6 cooperate with the threads on the threaded pins 5. It sets a threaded pin shaft, which is combined with a nut and a cotter pin during tightening. The nut can be tightened with the threaded pin shaft by means of thread cooperation, and the tightening position can be adjusted. When looseness occurs during later use, timely tightening adjustment can be performed without disassembling the entire chain. Maintenance is more convenient, the firmness of the connection position is more reliable, and it has an anti-loosening effect during long-term use. It can ensure the smooth operation of the chain and extend the overall service life of the chain.
[0013] Preferably, an integral fastening and clamping groove is provided on the outer side of the other end of the head of the threaded pin 5. When the nut end is fastened, a clamping tool can be used at the other end to make the fastening operation more convenient and the fastening process safer.
[0014] 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.
