[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Please see Figures 1-5 This utility model provides a technical solution: a polyester tool bag with a detachable inner liner, including a tool bag body 1. A covering cloth 4 is provided at the upper end of the tool bag body 1. One end of the covering cloth 4 is fixed to one side of the tool bag body 1, and the other end is glued to the other side of the tool bag body 1 to cover the opening of the tool bag body 1 and cover the tools inside the tool bag body 1. When in use, one end of the covering cloth 4 is peeled off from the tool bag body 1 to expose the tools. Side pockets 2 are provided at both the left and right ends of the tool bag body 1 for storing some small tools separately, making it more convenient to use. Handles 3 are fixedly installed at the front and rear ends of the tool bag body 1 for easy carrying of the tool bag body 1.
[0024] The tool bag body 1 has a detachable inner liner 13 installed inside. The four sides of the inner end of the tool bag body 1 are fixedly installed with Velcro round loop layers 6, and the four sides of the outer end of the inner liner 13 are fixedly installed with Velcro barbed layers 14. When the inner liner 13 is inside the tool bag body 1, the Velcro barbed layers 14 and the Velcro round loop layers 6 are glued to each other, which makes it easy to disassemble and assemble the inner liner 13, thus making it easy to clean.
[0025] Specifically, by placing the inner liner 13 inside the tool bag body 1, the Velcro barbed layer 14 and the Velcro rounded layer 6 are glued together, thereby fixing the inner liner 13 inside the tool bag body 1. When the inner liner 13 needs to be cleaned, it can be pulled out from the tool bag body 1, making it easy to disassemble and clean the inner liner 13.
[0026] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the inner end of the tool bag body 1 is provided with support components on all four sides for supporting the inner liner 13 and the tool bag body 1. The support components include limiting sleeves 7 fixed to the four sides of the inner end of the tool bag body 1 and elastic support rods 10. The limiting sleeves 7 are cylindrical, with the lower end of the limiting sleeves 7 fixed to the bottom end of the tool bag body 1. The upper end of the limiting sleeves 7 is fixedly connected to the tool bag body 1 by connecting straps 8, thus fixing the limiting sleeves 7. A Velcro round loop layer 9 is fixedly installed on one side of the upper end of the limiting sleeves 7, and a Velcro barbed layer 11 is fixedly installed on the other side. When the elastic support rod 10 is inserted into the limiting sleeves 7, the Velcro barbed layer 11 and the Velcro round loop layer 9 adhere to each other, fixing the elastic support rod 10. The elastic support rod 10 supports the four ends of the tool bag body 1 and shapes the tool bag body 1.
[0027] The outer wall of the limiting sleeve 7 is fixedly installed with a Velcro round pile layer 4 12, and the four corners of the outer end of the inner liner 13 are fixedly installed with Velcro barbed layers 4 15. The Velcro barbed layers 4 15 and the Velcro round pile layer 4 12 are bonded together, and the inner liner 13 is fixed to the outer end of the limiting sleeve 7, thereby fixing the four ends of the inner liner 13 to the inner wall of the tool bag body 1, making the inner liner 13 fit more closely inside the tool bag body 1, and also providing support for the inner liner 13.
[0028] like Figure 2 and 5 As shown, in some embodiments, a Velcro round loop layer 5 is fixedly installed on the bottom inner end of the tool bag body 1, and a Velcro barbed layer 16 is fixedly installed on the outer wall of the lower end of the inner liner 13. More specifically, by bonding the Velcro barbed layer 16 and the Velcro round loop layer 5, the bottom end of the inner liner 13 is fixed, so that the bottom end of the inner liner 13 and the bottom end of the tool bag body 1 fit together more closely.
[0029] In actual use, first fix the elastic support rod 10 inside the limiting sleeve 7, then place the inner liner 13 inside the tool bag body 1, and let the hook and loop layer 14 and the hook and loop round layer 6 stick together, let the hook and loop layer 16 and the hook and loop round layer 15 stick together, and let the hook and loop layer 45 and the hook and loop round layer 42 stick together, thereby fixing the inner liner 13 inside the tool bag body 1. When it is necessary to clean the inner liner 13, simply pull the inner liner 13 out of the tool bag body 1, which makes it easy to disassemble and clean the inner liner 13.
[0030] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
