Description

Technical Field

[0001] This utility model relates to the field of tensioning device technology, specifically to an adjustable sleeping pants tensioning device. Background Technology

[0002] Overnight panties (also known as "comfort panties," "night panties," or "pant-style sanitary napkins") are disposable pant-style sanitary products designed specifically for women, primarily for protection during menstruation, postpartum, or when there is heavy flow. They resemble boxer briefs in appearance but integrate a highly absorbent core, leak-proof side panels, and other features, providing 360° wrap-around protection while balancing comfort and leak prevention. They are especially suitable for use at night, during exercise, or for extended periods of activity.

[0003] In the production process of overnight pants, the installation of elastic bands is one of the key steps. Elastic bands can tightly wrap around the waist curve to prevent the overnight pants from slipping or shifting. Currently, during the installation process, elastic bands need to be connected to the overnight pants in a stretched state, usually by means of adhesive or hot melt glue.

[0004] The existing tensioning device includes a base and three tensioning posts fixedly and equidistantly on the upper surface of the base. Currently, when installing elastic bands onto overnight pants, the elastic band must first be stretched and stretched out onto the three tensioning posts to maintain tension. Then, the waistband of the overnight pants is slipped onto the elastic band, and the elastic band is installed onto the overnight pants using adhesive or hot melt glue. After installation, the overnight pants are removed from the three tensioning posts. The elastic band retracts, causing the waistband of the overnight pants to contract and form folds, thus giving the product a body-hugging elasticity (such as a tighter waist and leak-proof leg area).

[0005] However, the current tensioning device has three tensioning columns fixed on the chassis, making it impossible to adjust the position of the three tensioning columns on the chassis synchronously according to the tensioning requirements of the elastic band. As a result, the tension of the elastic band cannot be adjusted, making its use relatively limited. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an adjustable tensioning device for sleeping pants.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable sleeping pants tensioning device, comprising a base, a chassis disposed at the upper end of the base, a rotating column rotatably disposed between the base and the chassis, at least three sliding waist holes penetrating the chassis, at least three tensioning rods slidably disposed on the chassis and respectively located in each sliding waist hole, at least three drive plates disposed around the rotating column and located below the sliding waist holes, a linkage through hole penetrating each drive plate and gap-fitting with the tensioning rod, and a rotating device disposed between the base and the rotating column.

[0008] A further improvement is that there are three sliding waist holes, tension rods, and drive plates. The three sliding waist holes are inclinedly opened on the chassis and are equidistantly arranged in a ring around the central axis of the chassis. The three drive plates are inclinedly intersected with the three sliding waist holes.

[0009] A further improvement is that there are four sliding waist holes, tension rods, and drive plates in total. The four sliding waist holes are horizontally opened on the chassis and are equidistantly arranged in a ring around the central axis of the chassis. The four drive plates are inclined and intersecting with the four sliding waist holes.

[0010] A further improvement is that the base and the chassis are fixedly connected by a connecting column.

[0011] A further improvement is that each of the drive plates is fixedly connected to the periphery of the rotating column via a connecting block.

[0012] A further improvement is that the tensioning rod is provided with an upper limit plate and a lower limit plate, the lower end of the upper limit plate abutting against the upper end surface of the chassis, and the upper end of the lower limit plate abutting against the lower end surface of the drive plate.

[0013] A further improvement is that the rotating device includes a first toothed disc disposed on the rotating column, a rotating motor with its fixed end disposed on the upper end of the base and located on one side of the first toothed disc, and a second toothed disc disposed on the output end of the rotating motor and meshing with the first toothed disc.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When it is necessary to tension and stretch the elastic band, the elastic band is stretched and spread out and fitted onto the three tensioning columns. The elastic band is kept taut by the three tensioning columns. If it is necessary to increase or decrease the stretching amplitude of the elastic band, the rotating column is controlled to rotate by the rotating device, thereby driving the three drive plates to move circumferentially at the same time. At this time, by changing the position of the drive plates, each tensioning rod in each sliding waist hole moves closer or further away from the central axis of the chassis. The position of the three tensioning columns on the chassis can be adjusted synchronously according to the tensioning requirements of the elastic band. Alternatively, the elastic band can be fitted onto the three tensioning columns, and then the rotating device can be controlled to drive the rotating columns. The tension of the elastic band can be adjusted according to the size of the sleeping pants, making it more versatile in use.

[0015] Further benefits: The diameter of the first toothed disc is larger than that of the second toothed disc, which can reduce the rotational speed of the rotating column driven by the first toothed disc when the rotating motor drives the second toothed disc to rotate. This makes it easier for operators to start and control the rotating motor according to the rotational speed of the rotating column. Attached Figure Description

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figure 1 As shown, the technical solution adopted in this specific embodiment is: an adjustable overnight panty tensioning device, including a base 1, a chassis 2 disposed at the upper end of the base 1, a rotating column 3 rotatably disposed between the base 1 and the chassis 2, at least three sliding waist holes 4 penetrating the chassis 2, at least three tensioning rods 5 slidably disposed on the chassis 2 and respectively located in each sliding waist hole 4, at least three drive plates 6 disposed around the rotating column 3 and located below the sliding waist holes 4, a linkage through hole 7 penetrating each drive plate 6 and clearance-fitting with the tensioning rods 5, and a rotating device disposed between the base 1 and the rotating column 3. The upper and lower ends of the rotating column 3 are connected between the base 1 and the chassis 2 by bearings.

[0026] There are three sliding waist holes 4, tension rods 5, and drive plates 6. The three sliding waist holes 4 are obliquely formed on the chassis 2 and are equidistantly arranged in a ring around the central axis of the chassis 2. The three drive plates 6 are obliquely intersecting the three sliding waist holes 4. When there are three sliding waist holes 4, tension rods 5, and drive plates 6, the positions and angles of the sliding waist holes 4 and drive plates 6 are as follows: Figure 2 As shown, the sliding waist hole 4 is inclined to the central axis of the chassis 2, and the drive plate 6 is also inclined to the sliding waist hole 4. The drive plate 6 is vertically installed on the rotating column 3 by bolts or welding, and each drive plate 6 is arranged equidistantly in a ring on the rotating column 3.

[0027] There are four sliding waist holes 4, tension rods 5, and drive plates 6 in total. The four sliding waist holes 4 are horizontally positioned on the chassis 2 and are equidistantly arranged in a ring around the central axis of the chassis 2. The four drive plates 6 are arranged obliquely and intersectingly with the four sliding waist holes 4. When there are four sliding waist holes 4, tension rods 5, and drive plates 6, the positions and angles of the sliding waist holes 4 and drive plates 6 are as follows: Figure 3 , Figure 4 As shown, the sliding waist hole 4 is set perpendicular to the central axis of the chassis 2, while the drive plate 6 is set at an inclined angle to the sliding remote control.

[0028] The base 1 and the chassis 2 are fixedly connected by connecting posts 8. There are at least three connecting posts 8, arranged equidistantly in a ring between the base 1 and the chassis 2. Both the base 1 and the chassis 2 are circular, or the base 1 is a square disk and the chassis 2 is a circular disk. The upper ends of the connecting posts 8 are installed between the base 1 and the chassis 2 by welding or bolting.

[0029] Each of the drive plates 6 is fixedly connected to the periphery of the rotating column 3 via a connecting block 9. For example... Figure 3 , Figure 4 As shown, the number of connecting blocks 9 corresponds to the number of drive plates 6, and the connecting blocks 9 are located on one side of the drive plate 6. The connecting blocks 9 fix the rotating column 3 to the drive plate 6 by welding or bonding.

[0030] The tensioning rod 5 is respectively provided with an upper limit plate 10 and a lower limit plate 11. The lower end of the upper limit plate 10 abuts against the upper end surface of the base plate 2, and the upper end of the lower limit plate 11 abuts against the lower end surface of the drive plate 6. The diameter of the upper limit plate 10 is larger than the diameter of the sliding hole 4, and the diameter of the lower limit plate 11 is larger than the diameter of the linkage through hole 7. A gap is formed between the upper limit plate 10 and the upper end surface of the base plate 2 to allow the upper limit plate to move on the upper end surface of the base plate 2. A corresponding gap is also formed between the lower limit plate 11 and the lower end of the drive plate 6. This gap does not affect the movement of the tensioning rod 5 and can also maintain the stability of the tensioning rod 5.

[0031] By setting the upper limit plate 10 and the lower limit plate 11, the tension rod 5 can be stably held between the sliding waist hole 4 and the drive plate 6, preventing the tension rod 5 from falling out of the sliding waist hole 4 and the linkage through hole 7 when it moves.

[0032] The rotating device includes a first geared disc 12 mounted on the rotating column 3, a rotating motor 13 with its fixed end located on the upper end of the base 1 and on one side of the first geared disc 12, and a second geared disc 14 mounted on the output end of the rotating motor 13 and meshing with the first geared disc 12. The rotating motor 13 is a servo motor, and its fixed end is bolted to the base 1.

[0033] The working principle of this utility model is as follows: When the elastic band needs to be tensioned, the elastic band is stretched and placed on three tensioning columns. The elastic band is kept taut by the three tensioning columns. If it is necessary to increase or decrease the tension of the elastic band, the rotating column 3 is controlled to rotate by the rotating device, thereby driving the three drive plates 6 to move circumferentially at the same time. At this time, by changing the position of the drive plates 6, each tensioning rod 5 moves closer or further away from the central axis of the chassis 2 in each sliding waist hole 4. The position of the three tensioning columns on the chassis 2 can be adjusted synchronously according to the tensioning requirements of the elastic band. Alternatively, the elastic band can be placed on the three tensioning columns, and then the rotating device can be controlled to drive the rotating column 3. The tension of the elastic band can be adjusted according to the size of the sleeping pants, making it versatile in use. The diameter of the first toothed disc 12 is larger than the diameter of the second toothed disc 14. When the rotating motor 13 drives the second toothed disc 14 to rotate, the rotation speed of the first toothed disc 12 driving the rotating column 3 can be reduced. This allows the operator to easily start and control the rotating motor 13 according to the rotation speed of the rotating column 3.

The model numbers of the individual components are not the subject of this utility model's protection and are already known technology.
