Description

Technical Field

[0001] The utility model relates to the technical field of clothing, in particular to a pair of trousers with adjustable waistline. Background Art

[0002] Trousers are a kind of clothing mainly used in office or social occasions, and generally need to be worn with a belt. The specific structure of the trousers can refer to the Chinese patent with announcement number CN201504579U, which discloses a kind of trousers, which includes a waistband and trouser legs, a plurality of belt loops are arranged on the waistband, and a fixing member for hanging the belt head is also arranged on the waistband.

[0003] The above structure is a common trouser structure at present. The waist circumference of the trousers is fixed. Once the wearer becomes thinner or fatter, the waist circumference of the trousers will not match the waist. If the wearer becomes thinner, the waist can be tightened with the help of a belt. If the wearer becomes fatter, the wearer can only give up the trousers. Therefore, it is necessary to design a pair of trousers with an adjustable waist. Utility Model Content

[0004] Aiming at the shortcoming that the waist circumference of existing trousers is fixed and cannot be adjusted, the utility model aims to provide a pair of trousers with adjustable waist circumference.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A pair of trousers with adjustable waist, comprising a trouser body, a waist belt built in the trouser body, an adjusting mechanism for increasing or decreasing the waist size by rolling up the waist belt, the adjusting mechanism comprising a mounting box fixed to the trouser body, first through slots located on both sides of the mounting box for inserting the waist belt, a rolling component arranged in the mounting box and connected to the waist belt and capable of rolling up or releasing the waist belt at the same time, and a limiting component arranged on the mounting box for limiting the rotation of the rolling component.

[0007] By adopting the above scheme, compared with the existing trousers, the trousers in this scheme use a rolled-up belt to adjust the waist size. The rolled-up belt will be wrapped around the outer surface of the rolling component. If a person becomes thinner, the waist size of the trousers can be reduced by rotating the rolling component a proper number of times when adjusting the trousers. If a person becomes fatter, the waist size of the trousers can be increased by rotating the rolling component a proper number of times in the opposite direction when adjusting the trousers. Therefore, the trousers in this scheme can adapt to the changes in the wearer's body shape and are very convenient to wear.

[0008] Preferably, the rolling component includes a turntable arranged in an installation box, a rotating shaft protruding from the end of the turntable facing away from the trousers body and inserted into the installation box, and an operating block arranged outside the installation box and fixedly connected to the rotating shaft. The turntable moves axially along the rotating shaft as the operating block is pulled or pressed, and rotates concentrically with the rotating shaft as the operating block is rotated.

[0009] Preferably, the outer ring wall of the turntable is recessed with an annular groove for limiting the axial sliding of the belt along the turntable, and the two ends of the belt are respectively fixed in the annular groove.

[0010] By adopting the above scheme, when rolling up, the wearer only needs to rotate the operating part outside the installation box to drive the turntable to rotate. Since the two ends of the belt are fixed on the turntable, when the turntable rotates, the belt will automatically wind in the annular groove. The side wall of the annular groove can prevent the belt from slipping out and loosening, causing the waist circumference of the trousers to change.

[0011] Preferably, the outer ring wall of the turntable is recessed with an annular groove for limiting the axial sliding of the belt along the turntable, and a second through groove for the belt to pass through is provided in the radial direction of the annular groove. After the belt passes through the second through groove, both ends are fixedly connected to the trouser body.

[0012] The above-mentioned scheme is adopted as an optimization scheme of the turntable structure. The second through slot on the turntable is for facilitating the connection between the belt and the turntable. When making the trousers, it is only necessary to pass the belt through the second through slot and then fix the ends of the belt to each other in a ring shape. This connection method is a relatively common connection method in the clothing field and is easier to produce.

[0013] Preferably, the limiting component includes a first toothed disc concentric with the rotating shaft and protruding on the inner wall of the side of the installation box close to the operating block, a second toothed disc concentrically protruding on one end of the rotating disc close to the operating block and engaging with the first toothed disc when the rotating disc approaches the first toothed disc, and an elastic member is sleeved on the rotating shaft between the operating block and the installation box at both ends, elastically abutting against the two and used to drive the second toothed disc to be in a state of engagement with the first toothed disc.

[0014] Preferably, a mounting groove is provided on one side of the operating block facing the mounting box, and the elastic member includes a spring whose end is fixed in the mounting groove. The spring abuts against the mounting box to drive the operating block away from the mounting box, and a fitting gap is left between the operating block and the mounting box for the rotating shaft to move when the operating block is pressed.

[0015] With the above scheme, since the operating block and the rotating shaft are fixedly connected, when the operating block is not subjected to force, the spring drives the operating block away from the installation box, which drives the rotating shaft to move axially, driving the second gear disc to engage with the first gear disc. Then, the adjustment method of the trousers in this scheme is to press the operating block and then rotate the operating block to start adjusting the waist circumference of the trousers. After adjustment, release the operating block, and the two gear discs automatically engage under the action of the spring. The setting of the spring simplifies the steps of adjusting the waist circumference.

[0016] Preferably, the openings of the first through groove and the second through groove are provided with rounded corners.

[0017] By adopting the above solution, the rounded corners can reduce the wear of the belt by the installation box and the turntable when the trousers are worn and the waistline is adjusted.

[0018] The utility model has remarkable technical effects due to the adoption of the above technical scheme: compared with the existing trousers, the trousers in the present scheme adopt the method of rolling up the belt to adjust the waist size, and the rolled up belt will be wound around the outer surface of the rolling component. If a person becomes thinner, the waist size of the trousers can be reduced by rotating the rolling component a proper number of circles when adjusting the trousers. If a person becomes fatter, the waist size of the trousers can be increased by rotating the rolling component a proper number of circles in the opposite direction when adjusting the trousers. Therefore, the trousers in the present scheme can adapt to the changes in the wearer's body shape and are very convenient to wear. BRIEF DESCRIPTION OF THE DRAWINGS
