Description

Technical Field

[0001] This application relates to the field of knotting equipment technology, and in particular to a spiral belt knotting device. Background Technology

[0002] In the garment manufacturing process, especially in the production of pants such as sports pants and elastic pants, it is usually necessary to thread the drawstring into the drawstring holes in the pants.

[0003] A search revealed that Chinese Patent CN214904094U discloses a quick waistband threading auxiliary device for sports pants, which effectively improves work efficiency and ensures smooth threading of the waistband throughout the process. It enhances the adaptability of the device and has the advantages of being convenient, efficient, and quick to use. However, the device uses pull teeth to prevent the waistband from falling off, which makes it difficult to thread the waistband into the threading hole, resulting in inconvenience in operation. Therefore, a spiral waistband threading device is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 This utility model provides a technical solution for a spiral belt threading and knotting device:

[0027] A spiral belt threading device includes a threading loop 1 and a support part 2 fixedly connected to the end of the threading loop 1, a threading connector 3 fixedly connected to the starting end of the threading loop 1, a threading opening 4 on the surface of the threading connector 3, and a locking structure 5 installed inside the threading opening 4. The locking structure 5 is used to lock the belt in one direction.

[0028] Specifically, by setting a locking structure 5, the waist belt can be smoothly inserted into the rope opening 4. The locking structure 5 locks the inserted waist belt in one direction to prevent it from falling back and detaching from the rope opening 4. Compared with the existing technology that uses rope teeth to achieve two-way locking, it has the effect of making it easier to insert the waist belt into the rope opening 4 and improving production efficiency.

[0029] The locking structure 5 includes two locking plates 51 that are rotatably disposed in the rope opening 4. The two locking plates 51 are arranged in a V-shape. The sum of the lengths of the two locking plates 51 is greater than the width of the rope opening 4, and the ends of the two locking plates 51 that are close to each other lock the waist belt that is retracting.

[0030] The cord insertion port 4 has an inlet end 41 and an outlet end 42. The inlet end 41 corresponds to the V-shaped opening formed by the two locking plates 51. When in use, the belt is inserted from the inlet end 41 through the two V-shaped openings to the outlet end 42. During insertion, the belt can pass smoothly between the two locking plates 51 due to the rotational connection of the two locking plates 51. When the belt retracts, the belt drives the two locking plates 51 to rotate in the opposite direction under the action of friction, so that one end of the two locking plates 51 moves closer to each other, thereby clamping and locking the belt to prevent it from retracting.

[0031] A rotating shaft 6 is rotatably connected between the inner bottom wall and the inner top wall of the rope-threading port 4. The locking plate 51 is fixedly connected to the surface of the rotating shaft 6. By setting the rotating shaft 6, the locking plate 51 can rotate freely.

[0032] The locking plate 51 has a groove 511 on its front side. A torsion spring 7 is sleeved on the surface of the rotating shaft 6. One end of the torsion spring 7 is fixedly connected to the inner wall of the rope opening 4, and the other end of the torsion spring 7 is fixedly connected to the inner wall of the groove 511. By setting the torsion spring 7, it can be ensured that the locking plate 51 and the waist belt are in a close fit. When the waist belt retracts, it can be ensured that the waist belt can drive the locking plate 51 to move due to the friction.

[0033] A friction part 512 is provided at the end of the locking plate 51 away from the rotating shaft 6. The friction part 512 increases the friction between the locking plate 51 and the belt so that when the belt retracts, it drives the two locking plates 51 to close together at the ends that are close to each other. By providing the friction part 512, the friction between the locking plate 51 and the belt is further improved, ensuring the reliability of the belt driving the locking plate 51 to move. The friction part 512 protrudes from one end of the locking plate 51. The friction part 512 can be in the form of a dot or a strip. In the figure, the friction part 512 is in the form of a strip.

[0034] The top of the cord threading connector 3 is provided with a recessed groove 31, and the inner bottom wall of the recessed groove 31 is provided with a limiting groove 32. A sliding rod 8 is slidably connected in the limiting groove 32. The bottom end of the sliding rod 8 is fixedly connected to the locking plate 51. The top end of the sliding rod 8 is lower than the highest point of the cord threading connector 3. By setting the sliding rod 8, the sliding rod 8 can be moved to drive the two locking plates 51 to move, so that a channel is formed between the two, which makes it easy to thread a softer belt. At the same time, it is convenient for the user to take out the belt through the cord threading opening 4 after threading the cord.

[0035] The threading loop 1 is spiral-shaped, and the beginning and end of the threading loop 1 are staggered. The staggered beginning and end of the threading loop 1 facilitate the user's operation of putting on the waistband and avoids interference between the two when they are on the same plane.

[0036] The support part 2 includes a base 21, and a sleeve 22 is fixedly connected to the upper surface of the base 21. The end of the rope loop 1 is integrally formed with a connecting rod 11 extending downward in the vertical direction. The connecting rod 11 is slidably connected to the inner wall of the sleeve 22. The surface of the sleeve 22 is provided with a threaded hole, and the inner wall of the threaded hole is threaded with a locking bolt 9. By setting the sleeve 22 and the connecting rod 11, it is convenient to adjust the height of the rope loop 1. The height of the connecting rod 11 is positioned by the locking bolt 9.

[0037] Working principle: When using this spiral belt threading device, the user first inserts the drawstring inlet of the pants through the drawstring connector 3, then moves the waistband to move it on the drawstring loop 1, continuing to move until the drawstring connector 3 protrudes from the drawstring outlet on the waistband. Next, at the exposed drawstring connector 3, the belt is threaded from the inlet end 41 through the two formed V-shaped openings to the outlet end 42. During the threading process, due to the rotating connection of the two locking plates 51, the belt can smoothly pass through the two locking plates 51. When the belt retracts, the friction causes the two locking plates 51 to rotate in opposite directions, bringing one end of each locking plate 51 closer together. This clamps and locks the belt, preventing it from retracting. The waistband can then be removed from the drawstring loop 1 to thread the belt. Finally, the slide bar 8 is moved to move the ends of the two locking plates 51 apart and remove the belt from the drawstring connector 3. Compared to the existing technology that uses pull-cord teeth for bidirectional locking, this method makes it easier to thread the belt into the drawstring opening 4, thus improving production efficiency.
