Description

Technical Field

[0001] The utility model belongs to the technical field of cord buckles, and particularly relates to a trousers belt anti-drop buckle which can be operated with one hand. Background Art

[0002] At present, the patient gown pants on the market usually use elastic bands to tighten the belt. Although it is convenient for patients to put on, take off and change, the elastic band cannot be adapted to all patients due to the different waist circumferences of different patients. Some patients may have the phenomenon that the waist of the belt is too loose or too tight. Some existing patient gown pants use drawstrings or drawstrings with buckles to solve the above-mentioned phenomenon. However, if only the drawstring method is used, the patient needs to tie knots at both ends of the drawstring, which is not suitable for some patients with limited activities who cannot tie knots with both hands. If the drawstring is used with the buckle method, since the existing buckles are generally pressed spring type, one hand is still required to press the spring to complete the tightening or loosening of the drawstring, and the patient cannot operate with one hand. Especially for some patients with a single treatment task and a long treatment cycle, such as tumor patients, the inconvenience factors such as the long treatment time, the inability of family members to accompany for a long time, and the majority of nursing staff are female, make it extremely inconvenient for patients to loosen their belts before and after defecation during the treatment process.

[0003] Therefore, it is necessary to design a trousers belt anti-drop buckle which has a simple structure, is easy to operate, and can be operated with one hand. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a belt anti-drop buckle that can be operated with one hand. The structure is simple and easy to use. The patient can loosen and tighten the belt drawstring with one hand, which reduces the difficulty of loosening the belt for the patient and effectively improves the convenience and safety of the patient's toileting.

[0005] The technical solution of the utility model is:

[0006] The utility model provides a trouser belt anti-drop buckle which can be operated with one hand, comprising:

[0007] The buckle body is provided with two drawstring holes arranged in parallel, the drawstring holes longitudinally penetrate the buckle body, and the two ends of the belt drawstring pass through the two drawstring holes respectively. The belt drawstring is a flat drawstring and rope clips are provided at both ends of the drawstring;

[0008] The drawstring hole comprises a guide portion located at both end regions, a narrowing portion located in the middle region, and a transition portion connecting the guide portion and the narrowing portion, the aperture of the guide portion is larger than the aperture of the narrowing portion, and the outer diameter of the rope clip is larger than the aperture of the guide portion;

[0009] Wherein, the aperture of the narrowing portion is smaller than the width of the belt drawstring.

[0010] Preferably, the buckle body is further provided with a sliding hole perpendicular to the drawstring hole, and a pressing block movably arranged in the sliding hole;

[0011] The sliding hole is connected to the narrowed parts of the two drawstring holes.

[0012] Preferably, the length of the pressing block is greater than the minimum distance between the narrowing portions of the two draw-rope holes, and less than the maximum distance between the narrowing portions of the two draw-rope holes.

[0013] Preferably, the length of the pressing block is equal to the sum of the diameter of the rope-drawing hole and the vertical distance between the two rope-drawing holes.

[0014] Preferably, arc-shaped portions are provided at both ends of the pressing block.

[0015] Preferably, a plurality of the sliding holes and the pressing blocks are provided, and are spaced apart and distributed along the longitudinal direction of the buckle body.

[0016] Preferably, the cross section of the guide portion is circular or elliptical, the cross section of the narrowed portion is circular or elliptical, and the longitudinal section of the transition portion is trapezoidal.

[0017] Preferably, the buckle body is cylindrical or elliptical, and both ends thereof are provided with chamfered structures.

[0018] Compared with the prior art, the utility model has the following advantages and effects:

[0019] (1) A drawstring hole including a guide portion and a narrowing portion is used, and the aperture of the narrowing portion is smaller than that of the guide portion. A flat drawstring is inserted into the drawstring hole. Since the aperture of the narrowing portion is smaller than the width of the drawstring, the drawstring is folded and twisted in the narrowing portion and contacts the inner wall of the narrowing portion, thereby generating friction resistance that hinders the drawstring from moving along the drawstring hole. Only when a large external force is applied manually will the drawstring move along the drawstring hole, thereby achieving tightening or loosening of the belt;

[0020] (2) A cord clip is provided at the end of the belt drawstring, and the outer diameter of the cord clip is larger than the aperture of the guide portion, so that one end of the belt drawstring is stuck on the outside of the buckle body, thereby preventing the belt drawstring from falling off. At the same time, when tightening the belt, one end of the belt drawstring can be pulled by one hand, and the other end is stuck and fixed on the outside of the buckle body, so as to complete the tightening of the belt;

[0021] (3) A sliding hole and a pressing block are arranged in the buckle body. The pressing block is movably arranged in the sliding hole. When the drawstring in the drawstring hole on one side is pulled, the pressing block squeezes the drawstring in the drawstring hole on the other side, thereby increasing the friction of the drawstring in the drawstring hole on the other side, making it difficult to slide, thereby reducing the difficulty of tightening the belt with one hand.

[0031] like Figure 2 As shown, the buckle body 1 is provided with a drawstring hole 2 which runs longitudinally, and there are two drawstring holes 2, and both drawstring holes 2 are arranged parallel to the buckle body 1. The drawstring hole 2 includes a guide portion located at the end regions of both ends, a narrowing portion 22 located in the middle region, and a transition portion 23 connecting the guide portion and the narrowing portion 22, the guide portion has a circular cross section, the narrowing portion 22 has a circular cross section, the transition portion 23 has a trapezoidal longitudinal section, and its two ends are respectively connected to the guide portion and the narrowing portion 22.

[0032] In this embodiment, the belt drawstring 3 is a flat drawstring, and both ends of the belt drawstring are provided with a rope clip 31. Figure 3As shown in the content, it should be noted that the belt drawstring 3 is a mature existing technology in this field, and its specific structure and material are not described here one by one.

[0033] Combination Figure 2 , Figure 3 As shown, the aperture of the guide portion is larger than the aperture of the narrowing portion 22, the outer diameter of the rope clip 31 is larger than the aperture of the guide portion, and the aperture of the narrowing portion 22 is smaller than the width of the belt drawstring 3, so that the flat belt drawstring 3 entering the narrowing portion 22 is twisted and folded, and abuts against the inner wall of the narrowing portion 22 to generate friction that blocks the movement of the belt drawstring 3, so that the belt drawstring 3 will not slide relative to the drawstring hole 2 of the buckle body 1 in a normal tightening state, and only when a certain external force is applied artificially, the belt drawstring 3 will move relative to the drawstring hole 2 to achieve the tightening or loosening of the belt.

[0034] The belt drawstring 3 can be a whole drawstring worn at the waist of the patient gown, in which case both ends are provided with rope clips 31; or, the belt drawstring 3 is two independent drawstrings, the fixed end of each drawstring is fixed at the waist of the trousers, and the movable end of each drawstring is provided with a rope clip 31; wherein the rope clip 31 can specifically be a rope buckle or a hanging bell (hat bell), which is used to clamp and fix the end of the belt drawstring 3. This structure is a mature existing technology and will not be described in detail here.

[0035] like Figure 3 As shown, the two ends of the belt drawstring 3 are respectively inserted into the two drawstring holes 2 facing each other, and the two rope clips 31 at the end are distributed at the two ends of the buckle body 1. During the belt tightening process, the rope clip 31 at the end of the belt drawstring 3 in the upper drawstring hole 2 (taking this as an example, it can also be the lower drawstring hole 2) is stuck on the outside of the right guide part 21 of the buckle body 1. The patient only needs to pull one end of the rope clip 31 of the belt drawstring 3 in the lower drawstring hole 2 with one hand to complete the tightening of the belt.

[0036] Optionally, in some embodiments, the two ends of the belt drawstring 3 can also be inserted into the two drawstring holes 2 in the same direction (not shown in the figure). The specific usage and principle are the same as the above-mentioned opposite insertion method, which will not be repeated here.

[0037] Embodiment 2:

[0039] like Figure 4 As shown, the utility model relates to a trouser belt anti-drop buckle which can be operated with one hand, wherein the buckle body 1 is further provided with a slide hole 4 which is perpendicular to the two drawstring holes 2, and a pressing block 5 which is movably arranged in the slide hole 4.

[0040] The sliding hole 4 is connected to the narrowing parts 22 of the two drawstring holes 2, and the length of the pressing block 5 is greater than the minimum distance between the narrowing parts 22 of the two drawstring holes 2, and less than the maximum distance between the narrowing parts 22 of the two drawstring holes 2, that is, Figure 4 As shown, the length of the pressing block 5 is greater than the distance between the bottom wall of the upper drawstring hole 2 and the top wall of the lower drawstring hole 2, and is smaller than the distance between the top wall of the upper drawstring hole 2 and the bottom wall of the lower drawstring hole 2.

[0041] Optionally, in some embodiments, the length of the pressing block 5 is equal to the sum of the diameter of the narrowed portion 22 of the drawstring hole 2 and the vertical distance between the narrowed portions 22 of the two drawstring holes 2, so that one end of the pressing block 5 can be completely embedded in the slide hole 4, and the other end extends out of the slide hole 4 and into the drawstring hole 2, so that the belt drawstring 3 in the drawstring hole 2 on one side can pass smoothly, and the belt drawstring 3 in the drawstring hole 2 on the other side is squeezed by the pressing block 5 so that its movement along the direction of the drawstring hole is restricted, effectively reducing the difficulty of tightening the belt with one hand.

[0042] Arc-shaped portions are provided at both ends of the pressing block 5 so that the pressing block 5 can be pushed to move along the sliding hole 4 during the movement of the belt drawstring 3 .

[0043] Optionally, in some embodiments, the cross section of the sliding hole 4 is circular or elliptical, and the cross section of the compression block is circular or elliptical to match the sliding hole 4 .
