Description

Technical Field

[0001] This utility model relates to the field of infant and toddler products technology, specifically to a three-section adjustable tension strap for a waist stool that is easy to adjust, simple, and comfortable. Background Technology

[0002] For infants a few months old, parents often need to hold them for extended periods, especially since some infants may cry when held by other family members. Therefore, a baby carrier is extremely important when holding infants. A baby carrier can effectively reduce the burden of holding an infant. Currently, baby carriers are usually made by wrapping a belt around the adult's waist and holding the infant through the carrier on the belt. However, the belt on conventional baby carriers is fastened with Velcro at both ends, which does not allow for effective adjustment of the belt's tightness during use, making it inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a three-section adjustable tension strap for a waist stool that is structurally stable and easy to adjust.

[0004] To solve the above-mentioned existing technical problems, the present invention adopts the following solution: a three-section adjustable tension belt for a waist stool, including a waist stool body and a tension belt. The waist stool body is fixedly installed on the tension belt. The tension belt is composed of a first cloth strip, a connecting cloth sleeve and a second cloth strip. The first cloth strip is inserted and installed on the connecting cloth sleeve. The other end of the connecting cloth sleeve is connected to the second cloth strip. The second cloth strip is connected to the other end of the first cloth strip through a hook and loop fastener.

[0005] Preferably, a shrink knob is fixedly installed on the first fabric belt. The shrink knob is connected to the adjustment structure after passing through the connecting fabric sleeve via a pull rope. The other end of the adjustment structure is fixedly installed on the second fabric belt.

[0006] Preferably, the adjustment structure consists of several adjustment blocks, wherein the left adjustment block is placed inside the connecting fabric sleeve and connected to the shrink knob, and the right adjustment block is fixedly installed on the second fabric belt.

[0007] Preferably, the number of adjusting blocks inside the connecting fabric cover is odd, the number of adjusting blocks on the second fabric strip is even, and the adjusting blocks on the connecting fabric cover and the adjusting blocks on the second fabric strip are connected by a pull rope in a cross manner.

[0008] Preferably, the second fabric strip is provided with a tensioning band, which is fastened to the tensioning buckle on the first fabric strip.

[0009] Preferably, the retraction knob drives the second fabric strip to move along the inside of the connecting sleeve via a pull cord.

[0010] This utility model adopts the above-mentioned technical solution to provide a three-section adjustable tension strap for a waist stool. By optimizing the adjustment structure design and using a knob-type adjustment method, it has the following advantages compared with the prior art:

[0011] 1. By using the retraction knob to drive the pull rope, the second fabric belt moves along the connecting sleeve, making it easy to adjust the tension of the entire tension belt.

[0012] 2. The retraction knob moves multiple adjustment blocks simultaneously via a single pull rope, making operation simple. Attached Figure Description

[0014] Figure 2 This is a side view of the present invention.

[0015] Figure 3 This is a partial schematic diagram of the adjustment structure of this utility model.

[0016] In the diagram, the waist stool body is 1, the tension strap is 2, the first fabric strap is 3, the connecting fabric cover is 4, the second fabric strap is 5, the retraction knob is 6, the pull rope is 7, the adjustment structure is 8, and the adjustment block is 9. Detailed Implementation

[0017] like Figure 1 , 2 As shown in Figure 3, a three-section adjustable tension strap for a waist stool includes a waist stool body 1 and a tension strap 2. The waist stool body 1 is fixedly installed on the tension strap 2. The tension strap 2 consists of a first fabric strip 3, a connecting fabric sleeve 4, and a second fabric strip 5. The first fabric strip 3 is inserted into the connecting fabric sleeve 4, and the other end of the connecting fabric sleeve 4 is connected to the second fabric strip 5. The second fabric strip 5 is connected to the other end of the first fabric strip 3 by a hook and loop fastener. A retraction knob 6 is fixedly installed on the first fabric strip 3. The retraction knob 6 is connected to an adjustment structure 8 after passing through the connecting fabric sleeve 4 via a pull rope 7. The other end of the adjustment structure 8 is fixedly installed on the second fabric strip 5. The adjustment structure 8 consists of several adjustment blocks 9. The adjustment block 9 on the left is placed inside the connecting fabric sleeve 4 and connected to the shrink knob 6. The adjustment block 9 on the right is fixedly installed on the second fabric belt 5. The number of adjustment blocks 9 inside the connecting fabric sleeve 4 is odd, and the number of adjustment blocks 9 on the second fabric belt 5 is even. The adjustment blocks 9 on the connecting fabric sleeve 4 and the adjustment blocks 9 on the second fabric belt 5 are connected by a pull rope 7. The second fabric belt 5 is provided with a tension band 10, which is fastened to the tension buckle 11 on the first fabric belt 3. The shrink knob 6 drives the second fabric belt 5 to move along the inside of the connecting fabric sleeve 4 through the pull rope 7.

[0018] In actual use, the first fabric strap 3 and the second fabric strap 5 are connected by hook and loop fasteners. When using the waist stool, the first fabric strap 3 and the second fabric strap 5 are opened and then tied around the user's waist. The first fabric strap 3 and the second fabric strap 5 are then fastened with hook and loop fasteners. The infant is then placed on the waist stool body 1 for easy holding. The first fabric strap 3 has a retraction knob 6. When it is necessary to adjust the tightness of the tension strap 2, the retraction knob 6 is turned. The retraction knob 6 can be pulled by the pull rope 7 to move the second fabric strap 5 along the inner cavity of the connecting sleeve 4. Since the second fabric strap 5 is built into the connecting sleeve 4, the appearance of the entire tension strap 2 will not be affected when adjusting the second fabric strap 5. The retraction knob 6 is easy to operate and can be turned with one hand. When adjusting the tightness, it is not necessary to remove the entire tension strap 2 and re-tie it, making it more convenient to use.

[0019] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
