DETAILED DESCRIPTION

[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] See also Figure 1-5 The utility model provides a technical solution: an elastic cord for adjusting the length, comprising an elastic cord body 1, a movable plate 2, a limiting plate 3, a connecting sleeve 4, a spring 5, a fixing rod 6, a limiting sleeve 7, a groove 8, a thermoplastic elastic tube 9, a latex sleeve 10, a protective layer 11, a viscose fiber 12, a first polyurethane fiber 13 and a second polyurethane fiber 14. When the elastic cord for adjusting the length is used, Figure 1 , Figure 4 and Figure 5 The elastic cord body 1 is sequentially formed from the inside to the outside by a thermoplastic elastic tube 9, a latex sleeve 10 and a protective layer 11. Therefore, under the action of the thermoplastic elastic tube 9 provided on the latex sleeve 10, the breakage of the latex sleeve 10 is reduced, thereby achieving the purpose of preventing the elastic band from breaking. The protective layer 11 is fixed outside the latex sleeve 10. The protective layer 11 is formed by viscose fiber 12, a first polyurethane fiber 13 and a second polyurethane fiber 14. The viscose fiber 12 is glued and fixed to the outside of the latex sleeve 10. The cross-woven first polyurethane fiber 13 and the second polyurethane fiber 14 are glued and fixed to the outside of the viscose fiber 12. Therefore, the wear resistance of the first polyurethane fiber 13 and the second polyurethane fiber 14 can prevent the viscose fiber 12 from being worn, thereby extending the service life of the elastic band.

[0025] like Figure 1 , Figure 2 and Figure 3When the length of the elastic band needs to be adjusted, the movable plate 2 can be pressed downward first, so that the limit plate 3 fixedly connected under the movable plate 2 moves downward under the fitting limit of the connecting sleeve 4 and the elastic pressure of the spring 5, so that the fixed rod 6 fixedly connected to the lower side of the middle part of the limit plate 3 moves downward under the engagement limit of the fixed connection limit sleeve 7 in the middle part of the connecting sleeve 4, until the fixed rod 6 is nested in the groove 8 opened inside the connecting sleeve 4, so that the upper surface of the movable plate 2 and the upper surface of the connecting sleeve 4 are in the same horizontal plane, so as to achieve the purpose of disconnecting the limit plate 3 and the connecting sleeve 4 from the close fit with the elastic cord body 1 under the action of the spring 5, and disconnecting the restriction on the elastic cord body 1;

[0026] like Figure 1 , Figure 2 and Figure 3 Then, the elastic cord body 1 can be pulled as needed to adjust its length, and after the length adjustment is completed, the movable plate 2 can be released, so that the limit plate 3 drives the movable plate 2 to move up under the fit limit of the connecting sleeve 4, the elastic force of the spring 5, and the limit of the fixing rod 6 and the limit sleeve 7, so that the upper and lower sides of the elastic cord body 1 are tightly connected with the connecting sleeve 4 and the limit plate 3 respectively, so as to achieve the purpose of limiting the elastic cord body 1, thereby facilitating the adjustment and limitation of the length of the elastic band for use. The above components are all prior art and will not be described in detail here.
