Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of trouser hooks, in particular to an anti-slip and anti-rotation trouser hook. Background Art
[0002] In the prior art, there is a trouser hook. The hook is arranged at both ends of the trouser waist and fixes the width of the trouser waist by means of mutual buckling. The fixation of such a hook in the prior art is usually achieved by a stud button. For example, the button face and the stud button are respectively attached to both sides of the fabric. After the stud button passes through the fabric and the hook, the end of the stud button is folded back by machine pressing to fix the position of the button face. Although this process can reduce the processing technology and achieve rapid production, in actual application, due to the insufficient friction between the button face and the fabric, the button face will rotate and thus separate from the hook face. And as time goes by, this phenomenon will occur more and more frequently. Content of the Utility Model
[0003] Other features and advantages of the present utility model will be described in the following specification, and will become partially obvious from the specification, or will be understood by implementing the present utility model. The purpose and other advantages of the present utility model can be realized and obtained by the structure specifically pointed out in the specification and other specification drawings.
[0004] The purpose of the present utility model is to overcome the above deficiencies and provide an anti-slip and anti-rotation trouser hook. By adding an anti-rotation base and anti-slip bumps for increasing friction on the side of the hook face, button face in contact with the fabric, the friction between the button face, hook face and the fabric is increased, so as to achieve anti-rotation and anti-slip. Preferably, the anti-rotation base is square, and from the mechanical point of view, the rotation force is the largest, so as to tightly grasp the fabric and prevent the hook face and the button face from rotating, thus avoiding the occurrence of unhooking.
[0005] The present utility model provides an anti-slip and anti-rotation trouser hook, which includes a hook face formed by bending an upper metal sheet and a button face formed by bending a lower metal sheet. The hook face and the button face are buckled with each other. The hook face includes a first contact surface and a hook piece. An upwardly protruding first anti-rotation base is arranged on the first contact surface. A fixing hole is arranged on the first anti-rotation base. Several anti-slip bumps are arranged around the fixing hole on the first anti-rotation base. The button face includes a second contact surface and a button loop. A downwardly protruding second anti-rotation base is arranged on the second contact surface. The fixing hole and the anti-slip bumps are arranged on the second anti-rotation base.
[0006] The hook surface and the buckle surface are buckled with each other to limit both ends of the waistband. The hook surface is formed by bending the upper metal sheet into a first contact surface and a hook piece. The first contact surface contacts the inner side of the upper waistband. The provided first anti-rotation base and anti-slip bumps are used to increase the friction force, thereby preventing the rotation of the hook surface. Similarly, the buckle surface is formed by bending the lower metal sheet into a second contact surface and a buckle ring. The second contact surface contacts the fabric on the outer side of the lower waistband. The provided second anti-rotation base and anti-slip bumps are used to increase the friction force. It should be understood that the shapes of the first rotation base and the second rotation base can be circular, rectangular, square or other special-shaped shapes. The shapes are not limited herein. The number of anti-slip bumps is at least four and is evenly distributed on the base.
[0007] In some embodiments, both the first anti-rotation base and the second anti-rotation base are square. Preferably, the anti-rotation base is square. From a mechanical perspective, the rotation force required to generate a 90-degree rotation is the largest. Coupled with the cooperation of the anti-slip bumps, it can firmly grasp the fabric, prevent the rotation of the hook surface and the buckle surface, and thus prevent the unhooking situation.
[0008] In some embodiments, the upper metal sheet is provided with a reduced chamfer, and the width of the upper metal sheet is reduced after passing through the reduced chamfer. The space of the metal sheet with a larger width is used to reserve a position for the setting of the anti-rotation base, and the space of the remaining metal sheet can be appropriately reduced to reduce the overall weight and production cost of the trouser hook.
[0009] In some embodiments, the end of the upper metal sheet is provided with an arc-shaped upward curl, and the arc-shaped upward curl is located on the first contact surface. The provided arc-shaped upward curl part contacts the fabric and is used to increase the friction force with the fabric to prevent rotation and sliding.
[0010] In some embodiments, the hook piece is provided with a through hole, and the position of the through hole corresponds to the position of the fixing hole on the first anti-rotation base. The provided through hole is used to reserve space for the machine to extend into the hook surface to press the fixing tube. Preferably, the size of the through hole is larger than the size of the fixing hole.
[0011] In some embodiments, the two sides of the lower metal sheet are provided with outwardly extending flanks, and the two flanks are bent and aligned to form the buckle ring. The process of forming the buckle ring by bending the two side flanks is simpler than the process of directly producing an integral ring. At the same time, since the buckle ring is formed by combination, the user can manually press to adjust the size of the closing part, realizing the adjustable size of the buckle ring.
[0012] In some embodiments, an extension part is provided on the side of the second contact surface. The extending direction of the extension part is the same as the direction when the hook piece is buckled, and it is used to increase the contact area with the hook piece, effectively prevent unhooking, and maintain the stability during buckling.
[0013] In some embodiments, an arc-shaped notch is provided on the buckle, and the position of the arc-shaped notch corresponds to the position of the fixing hole on the second anti-rotation base. The arc-shaped notch also reserves space for the machine to extend into the inner part of the buckle surface to press the fixing tube, so as to avoid obstruction during pressing.
[0014] In some embodiments, a fixing buckle is further included. A fixing tube is extendedly provided on the fixing buckle, and the diameter of the fixing tube is adapted to the diameter of the fixing hole. The provided fixing buckle is a stud button. After the stud button passes through the fabric and the fixing hole, the machine extends from the other side and presses the fixing tube to cause the end to be folded back, so as to fix the position of the buckle surface or the hook surface. The fixing method of the stud button is a common setting in the market, and the specific process and structure can refer to the prior art.
[0015] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows:
[0016] The present utility model adds an anti-rotation base and a plurality of anti-slip bumps for increasing the friction force on the side where the hook surface, the buckle surface and the fabric are in contact, so as to increase the friction force between the buckle surface, the hook surface and the fabric, and realize anti-rotation and anti-slip. Preferably, the anti-rotation base is square, and from the mechanical point of view, the rotation force is the largest, so as to be able to firmly grasp the fabric and prevent the hook surface and the buckle surface from rotating, thus causing the situation of unhooking.
[0017] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure.
