Technical Field
[0001] The utility model belongs to the technical field of shoelace fasteners, and particularly relates to a shoelace fastener with a structure for preventing docking from falling off. Background Art
[0002] Shoelace fasteners, as an auxiliary tool, are mainly used to facilitate tightening or loosening shoelaces when people put on or take off shoes. With the development of technology, the design and functions of shoelace fasteners have become increasingly diverse to meet the needs of different people. Using shoelace fasteners can greatly save the time of tying shoelaces, especially for occasions where shoes need to be put on and taken off frequently. Some automatic rotating shoelace fasteners have a self-locking function to ensure that the shoelaces will not suddenly come loose during walking or exercising. Shoelace buckles made of materials such as silicone can provide better comfort and fit, reducing the sense of compression on the feet.
[0003] When the existing shoelace fasteners are in use, two shoelace fastener monomers are first installed at both ends of the shoelace, and then the two shoelace fastener monomers are connected to achieve the purpose of tightening the shoe upper. However, currently, the shoelace fastener monomers are usually connected to the shoelace by the extrusion of a spring, and due to the characteristics of the spring material, the shoelace fastener monomers are prone to slip and fall off from the shoelace, thus affecting the use of the shoelace fastener. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a shoelace fastener with a structure for preventing docking from falling off, aiming to solve the problem in the prior art that the existing shoelace fastener monomers are usually connected to the shoelace by the extrusion of a spring, and due to the characteristics of the spring material, the shoelace fastener monomers are prone to slip and fall off from the shoelace, thus affecting the use of the shoelace fastener.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A shoelace fastener with a structure for preventing docking from falling off, including a shoelace fastener outer cylinder, a shoelace fastener core cylinder and a shoelace. The inside of the shoelace fastener outer cylinder is connected with a shoelace fastener core cylinder. The shoelace penetrates through the inside of the shoelace fastener outer cylinder and the shoelace fastener core cylinder. A guiding slider is connected to the side surface of the shoelace fastener core cylinder. A guiding chute is opened on the surface of the shoelace fastener outer cylinder close to the guiding slider. A threaded cylinder is connected to the top of the shoelace fastener core cylinder. A threaded rod penetrates through the inside of the shoelace fastener outer cylinder, and a first limiting block is connected to the surface of the threaded rod.
[0006] To limit the movement direction of the shoelace fastener core cylinder, as an optimization of the shoelace fastener with a structure for preventing docking from falling off of the utility model, the guiding slider and the shoelace fastener outer cylinder form a sliding connection through the guiding chute.
[0007] To adjust the position of the shoelace fastener core cylinder, as an optimization of the shoelace fastener with a structure for preventing docking from falling off of the utility model, the threaded rod and the threaded cylinder are in threaded connection.
[0008] To limit the position of the threaded rod, as an optimization of the shoelace fastener with a structure for preventing butt joint from falling off in the present utility model, the threaded rod and the first limiting block are of an integral structure, and a rotating structure is formed between the threaded rod and the outer cylinder of the shoelace fastener.
[0009] As an optimization of the shoelace fastener with a structure for preventing butt joint from falling off in the present utility model, a connecting block is connected to the side surface of the outer cylinder of the shoelace fastener, a fixing slot is formed on the surface of the connecting block, a connecting bracket is connected to the side surface of the other outer cylinder of the shoelace fastener, a fixing insertion rod is inserted into the inside of the connecting bracket, a second limiting block is connected to the surface of the fixing insertion rod, a spring strip is connected between the second limiting block and the connecting bracket, and the spring strip is sleeved on the surface of the fixing insertion rod.
[0010] As an optimization of the shoelace fastener with a structure for preventing butt joint from falling off in the present utility model, the fixing insertion rod and the second limiting block are of an integral structure, the fixing insertion rod and the connecting bracket are in a sliding connection, and the longitudinal section of the fixing insertion rod is in an h shape.
[0011] As an optimization of the shoelace fastener with a structure for preventing butt joint from falling off in the present utility model, an elastic telescopic structure is formed between the second limiting block and the spring strip.
[0012] Compared with the prior art, the beneficial effects of the present utility model are:
[0013] In the present utility model, after the shoelace passes through the inside of the outer cylinder of the shoelace fastener and the core of the shoelace fastener, the threaded rod is rotated. Rotating the threaded rod can drive the threaded cylinder to move upward through the thread connection relationship. The upward movement of the threaded cylinder can drive the core of the shoelace fastener to move upward. In this way, the shoelace can be clamped by the dislocation between the outer cylinder of the shoelace fastener and the core of the shoelace fastener, so that it can be avoided that the shoelace fastener falls off from the shoelace surface due to insufficient fixation.
[0014] In the present utility model, when the fixing insertion rod is subjected to a pulling force, it can drive the second limiting block to move upward and compress the spring strip. Then, the other outer cylinder of the shoelace fastener drives the fixing slot to be inserted into the slot of the connecting bracket through the connecting block and releases the fixing insertion rod. At this time, the spring strip drives the fixing insertion rod to reset through the second limiting block under the action of its own elastic force. When the fixing insertion rod resets, it can be inserted into the inside of the fixing slot, so that the two outer cylinders of the shoelace fastener can be connected, thereby realizing the rapid tightening of the inclined surface.

A first limit block 8 is connected to the surface of the threaded rod 7.
[0024] Preferably: The guide slider 4 is slidably connected to the outer cylinder 1 of the shoelace device through the guide chute 5.
[0025] During specific use, when the core 2 of the shoelace device is subjected to a force, it can drive the guide slider 4 to slide inside the guide chute 5, so as to limit the movement direction of the core 2 of the shoelace device.
[0026] Preferably: The threaded rod 7 and the threaded cylinder 6 are in threaded connection.
[0027] During specific use, under the limiting effect of the guiding slider 4 and the guiding chute 5, when the threaded rod 7 moves upward, it can drive the threaded barrel 6 to move upward, and when the threaded barrel 6 moves upward, it can drive the shoelace device barrel core 2 to move upward.
