Due to various reasons such as overload operation, rust and aging, broken chains need to be replaced or repaired regularly. At present, when repairing a broken chain, it is necessary to reserve enough tensioning space, otherwise it is difficult to tighten the chain and install it.

[0003] Nowadays, the installation and locking of chains usually adopt traditional methods such as bolts and nuts, which has the problem of low installation efficiency. Therefore, we propose a new type of large chain installation locker. Utility Model Content

[0004] The purpose of the utility model is to provide a large chain installation locker to solve the problems raised in the above background technology.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the process of chain production, a locker is needed. The locker provided by the utility model is specially used for the installation and locking operations of large chains. In the process of using this equipment for installation and locking operations, it is necessary to ensure in advance that there are suitable chain cutting tools so as to adjust the chain length as needed, prepare chain connectors of appropriate types and sizes so as to connect the chains when necessary, ensure that the chain and gear surfaces are clean and free of deposits or old lubricants so that the new chain can operate normally, prepare appropriate chain lubricants for lubricating the newly installed chain to reduce friction and extend service life, and determine the correct installation order of the chain, usually by placing the chain along the gears first, and then using chain tools or manual devices to lock or connect the chain, thereby ensuring that the newly installed chain can operate normally and be used for a long time.

[0025] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a large chain installation locker, comprising:

[0026] A fixed square column 3, a movable square column 6 is slidably mounted on the inner side of the right end of the fixed square column 3, a blocking plate 7 is fixedly mounted on the right end of the movable square column 6, a limiting sleeve 4 is mounted on the outer surface of the movable square column 6, and two limiting sleeves 4 are mounted on the outer surface of the right end of the fixed square column 3;

[0027] A circular ring 2 is fixedly installed on one side of the fixed square column 3, and a protruding rod 10 is arranged inside the circular ring 2. The protruding rod 10 is threadedly installed on the fixed square column 3, penetrates the surface of the fixed square column 3, and extends to the inner side thereof.

[0028] A rotating block 1 is installed on the left end of the fixed square column 3, and a fixed screw 8 is fixedly connected to the rotating block 1. The fixed screw 8 is located inside the fixed square column 3. A mosaic plate 9 is fixedly installed inside the left end of the fixed square column 3, and a convex sleeve 12 is rotatably installed inside the mosaic plate 9.

[0029] like Figure 1As shown, it should be noted that: the movable square column 6 is slidably installed on the inner side of the fixed square column 3, and the blocking plate 7 is arranged to cooperate with the limiting sleeve 4 at the right end of the movable square column 6 to fix the clamping member 5. At the same time, the limiting sleeve 4 on the outer surface of the movable square column 6 can prevent the movable square column 6 from being completely immersed in the inner side of the fixed square column 3 during the movement inside the fixed square column 3. During the movement, the limiting sleeve 4 on the outer surface of the movable square column 6 will eventually rest against the right end of the fixed square column 3, thereby forming a small gap between the clamping members 5, and will not cause the two clamping members 5 to fit together to form a sealed state.

[0030] A fixing screw 8 is rotatably mounted inside the convex sleeve 12 , a hexagonal nut 13 is threadedly mounted on the outer wall of the right end of the fixing screw 8 , a fixing plate 11 is mounted on the outer surface of the hexagonal nut 13 , and a movable square column 6 is mounted on the outer wall of the fixing plate 11 .

[0031] A clamping piece 5 is installed at the bottom end of the fixed square column 3 . The clamping piece 5 is provided with a pointed end. The clamping piece 5 is located between the limiting sleeves 4 at the right end of the fixed square column 3 .

[0032] like Figure 3 As shown, it should be noted that: when the chain installation and locking operation is required, the fixed screw 8 can be driven to rotate by rotating the rotating block 1. During the rotation of the fixed screw 8, the length of the fixed screw 8 located on the right side of the hexagonal nut 13 becomes longer and longer, thereby driving the fixed square column 3 to move forward, and the movable square column 6 slides to the left on the inside of the fixed square column 3. In the process of the fixed square column 3 and the movable square column 6 approaching each other, the distance between the clamps 5 can be adjusted. The adjustment of the distance between the clamps 5 can meet the installation and locking work between chains at different distances, thereby improving the compatibility and diversity of the device.

[0033] A clamping member 5 is installed at the bottom end of the movable square column 6 , and the clamping member 5 is located between the blocking plate 7 and the limiting sleeve 4 at the right end of the movable square column 6 .

[0034] The left end of the movable square column 6 is provided with an arc groove, and the arc groove corresponds to the outer wall of the protruding rod 10. The outer wall of the protruding rod 10 is provided with a limiting ring, and the limiting ring is located on the inner side of the circular ring 2.

[0035] The fixing screw 8 itself is divided into two parts, the left part is a sliding surface, and the right part is a threaded surface. The protruding rod 10 and the convex sleeve 12 are both located on the sliding surface, and the hexagonal nut 13 is located on the threaded surface.

[0036] like Figure 2As shown, it should be noted that: in the process of continuously rotating the fixed screw 8, the position of the hexagonal nut 13 on the fixed screw 8 will change synchronously. When the hexagonal nut 13 moves to the sliding surface of the fixed screw 8, since there is no thread on the sliding surface, there is no need to continue to rotate the rotating block 1. By pushing the rotating block 1, the fixed square column 3 and the movable square column 6 can continue to approach each other. When the fixed square column 3 and the movable square column 6 approach each other, the arc groove set at the left end of the movable square column 6 is stuck on the outer surface of the protruding rod 10 to limit the movable square column 6.

[0037] To sum up, the large chain installation locker drives the fixed screw 8 to rotate by rotating the rotating block 1. During the rotation of the fixed screw 8, the fixed square column 3 and the movable square column 6 can be driven to approach each other. In the process of the fixed square column 3 and the movable square column 6 approaching each other, the distance between the clamping parts 5 changes synchronously, thereby being able to meet the installation and locking operations of different distances between chains. At the same time, by setting the limit sleeve 4, it is possible to avoid the clamping parts 5 from fitting together during the process of approaching each other, thereby forming a seal without the presence of gaps, and making it impossible to install and lock the chain.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
