Description

Technical Field

[0001] This utility model relates to the field of bag manufacturing technology, specifically to an adjustable and expandable polyester tool bag. Background Technology

[0002] Polyester is a synthetic fiber formed by the condensation polymerization of organic dicarboxylic acids and diols. Due to its high strength, high abrasion resistance, strong wrinkle resistance, chemical corrosion resistance, and easy care, it has gradually become the core choice for bag fabrics. Tool bags made from it have very high abrasion resistance and durability.

[0003] In existing technologies, traditional tool bags rely on adding polyester bags and strips to the outside to increase their capacity. However, this expansion only accommodates a small portion of the tools and cannot meet the requirement of holding a large number of tools after expansion. Therefore, this invention proposes an adjustable-capacity polyester tool bag to solve the aforementioned technical problems. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Example 1: Please refer to Figures 1-6 This utility model provides a technical solution: an adjustable and expandable polyester tool bag, comprising: a box body 1, with pull rods 3 fixedly connected to both the left and right sides inside the box body 1, and several steel balls 6 evenly arranged on the upper and lower sides of the pull rods 3, two-thirds of the steel balls 6 being inside the pull rods 3 and rotatably connected to the pull rods 3; two protruding strips 8 fixedly connected to the bottom inside the box body 1; a box body 2 slidably connected to one side of the box body 1, with side slide rails 4 fixedly connected to both the left and right sides inside the box body 2, and sliding grooves opened on both the upper and lower sides inside the side slide rails 4, with the other one-third of the steel balls 6 placed in the sliding grooves so that the side slide rails 4 are slidably connected to the pull rods 3; several holes are opened on the side of the two side slide rails 4 that are close to each other; two bottom slide rails 5 fixedly connected to the bottom inside the box body 2, and the bottom slide rails 5 are slidably connected to the protruding strips 8, providing support after the tool bag is expanded; the side slide rails 4 are slidably connected to the pull rods 3; and the outer sides of the box body 1 and the box body 2 are covered with polyester fabric 7.

[0022] Two pull rods 3 are fixedly connected to handles 21 at their ends away from the side slide rails 4. A long rod 9 is slidably connected inside the handles 21. A button 10 is fixedly connected to one side of the long rod 9, protruding through the outer wall of the pull rod 3. Two transmission rods 12 are fixedly connected to the two ends of the long rod 9 away from the button 10. Two springs 11 are fixedly connected to the side of the long rod 9 near the two transmission rods 12. The ends of the springs 11 away from the long rod 9 are fixedly connected to the inner wall of the pull rod 3. The pull rod 3 includes transmission rods 12 inside. Two round rods 13 are fixedly connected to the ends of the transmission rods 12 away from the long rod 9. The round rods 13 are connected to the limiting block 14. The two round rods 13 are connected to each other and pass through the interior of the limiting block 14. A positioning protrusion 16 is fixedly connected to one side of the limiting block 14, and a spring 15 is fixedly connected to the side of the limiting block 14 away from the positioning protrusion 16. The end of the spring 15 away from the limiting block 14 is fixedly connected to the inner wall of the pull rod 3. The bottom of the limiting block 14 is slidably connected to the inner wall of the pull rod 3. After the button 10 is pressed, the two transmission rods 12 are driven to move downward through the long rod 9, which in turn drives the round rods 13 to slide downward in the gap between the limiting blocks 14. The limiting block 14 is forced to slide inward, pulling the positioning protrusion 16 inward.

[0023] Specifically, when the tool kit needs to be expanded, pressing button 10 causes the two transmission rods 12 to move downwards via the long rod 9, which in turn causes the round rod 13 to slide downwards in the gap between the limiting blocks 14. The limiting blocks 14 slide to the right under force, pulling the positioning protrusion 16 inwards. At this time, pulling the pull rod 3 causes it to slide to the right under the action of the steel ball 6. Releasing button 10 causes button 10, transmission rod 12, round rod 13, limiting blocks 14, and positioning protrusion 16 to begin to reset under the action of spring 11 and spring 2 15. When pulled to the set position, the positioning protrusion 16 passes through the hole opened on the side slide rail 4. At this time, the parts are completely reset and fixed, completing the expansion.

[0024] Example 2: Based on Example 1, as follows Figure 1 , Figure 2 As shown, a cover 19 is fixedly connected to the outside of the polyester fabric 7. Several fasteners 18 are fixedly connected to the outside of the cover 19. Two Velcro straps 20 are fixedly connected to the upper inside of the cover 19. The polyester fabric 7 covers the outside of the box body 1 and the box body 2 to form the tool bag body. Two Velcro straps 20 are fixedly connected to the upper outside of the bag body. When the tool bag is closed, the two Velcro straps 20 stick together to form a protective effect. Four bag strap buckles 17 are fixedly connected to the four corners of the lower outside of the bag body to fasten the bag straps. Several fasteners 18 are fixedly connected to both the outside and inside of the bag body.

[0025] Specifically, when the tool bag is not expanded, the excess length of polyester fabric 7 is fixed to the normally used polyester fabric 7 by the fastening buckle 18. The male buckle of the fastening buckle 18 is fixedly connected to the normal polyester fabric 7, and the female buckle is fixedly connected to the excess polyester fabric 7. When expansion is needed, the male and female buckles are opened, thereby opening the fastening buckle 18. The box is pulled, and the excess polyester fabric 7 unfolds and covers the expanded box. When the tool bag is closed, the two Velcro straps 20 serve to fix the bag cover 19 and the bag body. The bag strap buckle 17 reserved at the bottom can be fastened to the bag strap for easy carrying.

[0026] In actual use, when the tool kit needs to be expanded, first open the fixing buckle 18, press the button 10, and then the long rod 9 drives the two transmission rods 12 to move downwards, which in turn drives the round rod 13 to slide downwards in the gap between the limiting blocks 14. The limiting block 14 slides to the right under the force, pulling the positioning protrusion 16 inwards. At this time, pull the pull rod 3. The pull rod 3 slides to the right under the sliding action of the steel ball 6. Release the button 10, and under the action of the first spring 11 and the second spring 15, the button 10, transmission rod 12, round rod 13, limiting block 14 and positioning protrusion 16 begin to reset. When pulled to the set position, the positioning protrusion 16 passes through the hole opened on the side slide rail 4. At this time, the parts are completely reset and fixed, and the outer polyester cloth 7 is fully unfolded to cover the expansion box, completing the expansion.

[0027] 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.
