Technical Field
[0001] This utility model belongs to the field of belt technology, and in particular relates to a detachable belt. Background Technology
[0002] Belt buckles on the market come in two types: one is a leather belt body with leather straps directly sewn together, and the other is a metal buckle directly attached to the leather belt body. Neither type allows for easy replacement of the buckle, strap, or belt body. This makes it inconvenient to replace the belt body when the belt length is incorrect, or to replace the strap or buckle if damaged. Summary of the Invention
[0003] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a detachable belt, characterized in that it includes:
[0004] The belt is a long, thin strip;
[0005] Bundle;
[0006] buckle;
[0007] First clamp;
[0008] The second clamp has a first mounting cavity and a second mounting cavity formed between the upper surface of the first clamp and the lower surface of the second clamp. The first mounting cavity is used to install a buckle, and the second mounting cavity is used to install a strap.
[0009] The third mounting cavity is located on the first clamp and is used to mount the belt body;
[0010] A fixing component, which is disposed on the first clamp, is used to fix the belt body;
[0011] The first clamp and the second clamp are clamped together by screws.
[0012] Furthermore, it also includes:
[0013] The first mounting cavity is formed by the semi-circular grooves on the upper surface of the first clamp and the lower surface of the second clamp.
[0014] The buckle has a rotating shaft located within the first mounting cavity.
[0015] Furthermore, it also includes:
[0016] The first and second clamps are both provided with clearance grooves, which are connected to the semi-circular groove.
[0017] The buckle has a buckle pin rotatably mounted on its rotating shaft, and the buckle pin is located in the clearance groove.
[0018] Furthermore, it also includes:
[0019] The mounting slot is provided on the first clamp;
[0020] The positioning post has two, both of which are located in the mounting groove and are fixedly connected to the first clamp.
[0021] Positioning holes are provided at both ends of the bundle, and the two ends of the bundle are respectively fitted onto two positioning posts through the positioning holes;
[0022] The second mounting cavity is formed by the mounting groove and the lower surface of the second clamp, and the gap between the upper surface of the positioning post and the lower surface of the second clamp is less than the thickness of the bundle.
[0023] Furthermore, it also includes:
[0024] A positioning piece is fixedly mounted on a first clamp, and the positioning piece is located between two positioning posts;
[0025] The two ends of the positioning piece extend toward the two positioning posts and are spaced apart from the two positioning posts. The lower surfaces of the two ends of the positioning piece and the bottom surface of the mounting groove form two positioning grooves. After the two ends of the bundle are respectively fitted onto the two positioning posts through positioning holes, the two ends of the bundle are respectively located in the two positioning grooves.
[0026] Furthermore, the fixing component includes:
[0027] A cover plate is provided at the upper opening of the third mounting cavity, and the cover plate is rotatably disposed in the opening to cover the opening of the third mounting cavity;
[0028] Fixing pins: Several fixing pins are fixedly provided at the lower end of the cover plate, and the fixing pins are located in the third mounting cavity;
[0029] When the cover plate is rotated upwards to open, the fixing pin will leave the third mounting cavity, and the side of the cover plate away from the mounting groove will be rotatably connected to the first clamp, and the fixing pin will also be located on the side of the cover plate away from the mounting groove.
[0030] Furthermore, it also includes:
[0031] The opening and closing slot is located on the second clamp;
[0032] Wherein, after the second clamp is fixedly connected to the first clamp by screws, the opening and closing groove of the second clamp corresponds to the side of the cover plate near the mounting groove.
[0033] The beneficial effects of this utility model are as follows:
[0034] 1. By setting a first clamp and a second clamp, the first clamp and the second clamp form a first mounting cavity and a second mounting cavity after installation. The first mounting cavity is used to install the buckle, and the second mounting cavity is used to install the buckle. When it is necessary to disassemble and replace the buckle or the buckle, only the first clamp and the second clamp need to be removed to replace the buckle or the buckle. At the same time, a fixing component and a third mounting cavity are set to facilitate the replacement of the belt body, making the replacement of the overall accessories more convenient.
[0035] 2. Because the buckle has a rotating shaft, the semi-circular groove is designed so that after the first clamp and the second clamp are installed, the first mounting cavity will be in the shape of a circular hole, which better fits the rotating shaft of the buckle. At the same time, it ensures that the rotating shaft of the buckle rotates smoothly in the first mounting cavity and prevents the buckle from disengaging from the first clamp or the second clamp.
[0036] 3. By setting the clearance groove, when the buckle is installed in the semi-circular groove, the buckle pin will be located in the clearance groove, thereby avoiding interference between the position of the buckle pin and the installation of the first clamp and the second clamp. At the same time, the position of the clearance groove has a limiting effect on the buckle pin, preventing the buckle pin from moving left and right on the rotating shaft.
[0037] 4. By setting positioning posts and positioning holes, the positioning effect is achieved during the installation of the bundle. At the same time, after the second clamp is installed on the first clamp, the gap between the upper surface of the positioning post and the lower surface of the second clamp is less than the thickness of the bundle, so that the two ends of the bundle in the installation groove will not detach from the positioning post, thus fixing the bundle.
[0038] 5. By setting positioning plates, after the positioning posts are inserted into both ends of the bundle, the ends of the bundle can be locked into the positioning groove formed between the positioning plates and the mounting groove. This prevents the ends of the bundle from lifting up before the second clamp and the first clamp are fixedly installed, and facilitates the replacement of other parts at the same time.
[0039] 6. By setting up a fixing component, the disassembly or installation of the belt body is convenient and quick, and it also prevents the belt body from detaching from the third mounting cavity when under stress, so that the overall fixing is quick and effective.
[0040] 7. By setting the opening and closing groove, when it is necessary to open the cover, it is convenient to apply force to one end of the cover through the opening and closing groove, so as to rotate and open the cover. Attached Figure Description

[0048] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the description of this application, it should be noted that the terminology used herein is only for describing specific implementations and is not intended to limit the exemplary implementations according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings indicate similar items, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0049] Example 1:
[0050] This embodiment provides a detachable belt, including:
[0051] The body 1 is a long, thin strip;
[0052] Bundle 2;
[0053] Buckle 3;
[0054] First clamp 4;
[0055] The second clamp 5 has a first mounting cavity 6 and a second mounting cavity 7 formed between the upper surface of the first clamp 4 and the lower surface of the second clamp 5. The first mounting cavity 6 is used to install the buckle 3, and the second mounting cavity 7 is used to install the tie 2.
[0056] The third mounting cavity 8 is opened on the first clamp 4 and is used to mount the belt body 1;
[0057] A fixing component is provided on the first clamp 4 for fixing the belt body 1;
[0058] The first clamp 4 and the second clamp 5 are clamped together by screws.
[0059] In this technical solution, after the second clamp 5 is installed onto the first clamp 4 with screws, a first mounting cavity 6 and a second mounting cavity 7 are formed between the upper surface contour of the first clamp 4 and the lower surface contour of the second clamp 5. Therefore, when the second clamp 5 is removed from the first clamp 4, the first mounting cavity 6 and the second mounting cavity 7 will be in an open state. At this time, the buckle 3 or the tie 2 can be inserted into the first mounting cavity 6 or the second mounting cavity 7. Then, the second clamp 5 is assembled with the first clamp 4 and locked with screws to realize the replacement or installation of the buckle 3 or the tie 2.
[0060] The first clamp 4 is also provided with a third mounting cavity 8 for fixing the belt body 1. In specific installation, one end of the belt body 1 is inserted into the third mounting cavity 8, and then the belt body 1 is fixed by a fixing component. The fixing component can be a screw (not shown in the figure) that is spirally set on the first clamp 4. The screw end is screwed into the third mounting cavity 8 to press one end of the belt body 1, thereby realizing the replacement or installation of the belt body 1.
[0061] Through this structural design, a first clamp 4 and a second clamp 5 are set up. After the first clamp 4 and the second clamp 5 are installed, a first mounting cavity 6 and a second mounting cavity 7 are formed. The first mounting cavity 6 is used to install the buckle 3, and the second mounting cavity 7 is used to install the tie 2. When it is necessary to disassemble and replace the buckle 3 or the tie 2, only the first clamp 4 and the second clamp 5 need to be removed to replace the buckle 3 or the tie 2. At the same time, a fixing component and a third mounting cavity 8 are set up to facilitate the replacement of the belt body 1, making the replacement of the overall accessories more convenient.
[0062] Example 2:
[0063] This embodiment provides a detachable belt, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0064] Furthermore, it also includes:
[0065] The first mounting cavity 6 is formed by the semi-circular groove 9 on the upper surface of the first clamp 4 and the lower surface of the second clamp 5.
[0066] The buckle 3 has a rotating shaft 10, which is located in the first mounting cavity 6.
[0067] In this technical solution, the first mounting cavity 6 is formed by the semicircular groove 9 of the first clamp 4 and the semicircular groove 9 of the second clamp 5. During installation, the rotating shaft 10 of the buckle 3 is placed in the semicircular groove 9 of the first clamp 4, and then the semicircular groove 9 of the second clamp 5 is covered with the semicircular groove 9 of the first clamp 4. After the two semicircular grooves 9 are closed, a first mounting cavity 6 is formed, the internal contour of which is a circular hole. The rotating shaft 10 of the buckle 3 will be located in the semicircular grooves 9 of the first clamp 4 and the second clamp 5, thereby installing the buckle 3 on the first clamp 4 and the second clamp 5.
[0068] With this structural design, since the buckle 3 has a rotating shaft 10, and by setting a semi-circular groove 9, after the first clamp 4 and the second clamp 5 are installed, the first mounting cavity 6 will be in the shape of a round hole, which better fits the rotating shaft 10 of the buckle 3. At the same time, it ensures that the rotating shaft 10 of the buckle 3 rotates smoothly in the first mounting cavity 6, and will not cause the buckle 3 to detach from the first clamp 4 or the second clamp 5.
[0069] Example 3:
[0070] This embodiment provides a detachable belt, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0071] Furthermore, it also includes:
[0072] The first clamp 4 and the second clamp 5 are both provided with a clearance groove 11, which is connected to the semi-circular groove 9.
[0073] A buckle pin 19 is rotatably mounted on the rotating shaft 10 of the buckle 3, and the buckle pin 19 is located in the clearance groove 11.
[0074] In this technical solution, a buckle pin 19 is rotatably provided on the rotating shaft 10 of the buckle 3. Generally speaking, most belt buckles 3 have a buckle pin 19, which is used to pass through the belt hole to adjust the tightness.
[0075] The clearance groove 11 is located in the middle of the first clamp 4 and the second clamp 5.
[0076] Through this structural design, by setting the clearance groove 11, when the buckle 3 is installed in the semi-circular groove 9, the buckle pin 19 will be located in the clearance groove 11, thereby avoiding the position of the buckle pin 19 from interfering with the installation of the first clamp 4 and the second clamp 5. At the same time, the position of the clearance groove 11 has a limiting effect on the buckle pin 19, which prevents the buckle pin 19 from moving left and right on the rotating shaft 10.
[0077] Example 4:
[0078] This embodiment provides a detachable belt, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0079] Furthermore, it also includes:
[0080] The mounting slot 12 is formed on the first clamp 4;
[0081] Positioning pin 13, having two of them, both of which are located in the mounting groove 12 and are fixedly connected to the first clamp 4;
[0082] Positioning holes 14 are provided at both ends of the bundle 2, and the two ends of the bundle 2 are respectively fitted onto two positioning posts 13 through the positioning holes 14.
[0083] The second mounting cavity 7 is formed by the mounting groove 12 and the lower surface of the second clamp 5, and the gap between the upper surface of the positioning post 13 and the lower surface of the second clamp 5 is less than the thickness of the bundle 2.
[0084] In this technical solution, when the bundle 2 needs to be installed, since the bundle 2 has positioning holes 14 at both ends, after the first clamp 4 and the second clamp 5 are disassembled, both ends of the bundle 2 are inserted into the mounting groove 12. One end of the bundle 2 is inserted into the mounting groove 12 from the left side of the first clamp 4, and the other end of the bundle 2 is inserted into the mounting groove 12 from the right side of the first clamp 4.
[0085] Then, the positioning holes 14 at both ends of the bundle 2 are respectively inserted onto the two positioning posts 13, thereby positioning the two ends of the bundle 2 through the cooperation of the positioning holes 14 and the positioning posts 13. Then, the second clamp 5 is installed on the first clamp 4. After installation, since the gap between the upper surface of the positioning post 13 and the lower surface of the second clamp 5 is less than the thickness of the bundle 2, the two ends of the bundle 2 in the mounting groove 12 will not detach from the positioning post 13, thereby fixing the bundle 2.
[0086] The positioning post 13 has a threaded hole 20, and the second clamp 5 has a through hole 21 corresponding to the threaded hole 20. When the second clamp 5 is fixedly connected to the first clamp 4, the threaded hole 20 and the through hole 21 are aligned, and then the screw is passed through the through hole 21 of the second clamp 5 and screwed into the threaded hole 20 of the positioning post 13, thereby locking the first clamp 4 and the second clamp 5. Through this setting, the presence of the screw fills the gap between the upper surface of the positioning post 13 and the lower surface of the second clamp 5, so that the tie 2 will not detach from the positioning post 13.
[0087] Through this structural design, the positioning post 13 and positioning hole 14 are set to achieve a positioning effect when the bundle 2 is installed. At the same time, after the second clamp 5 is installed on the first clamp 4, since the gap between the upper surface of the positioning post 13 and the lower surface of the second clamp 5 is less than the thickness of the bundle 2, the two ends of the bundle 2 in the installation groove 12 will not detach from the positioning post 13, thereby fixing the bundle 2.
[0088] Example 5:
[0089] This embodiment provides a detachable belt, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0090] Furthermore, it also includes:
[0091] A positioning piece 15 is fixedly mounted on the first clamp 4, and the positioning piece 15 is located between two positioning posts 13;
[0092] The two ends of the positioning piece 15 extend toward the two positioning posts 13 and are spaced apart from the two positioning posts 13. The lower surfaces of the two ends of the positioning piece 15 and the bottom surface of the mounting groove 12 form two positioning grooves 22. After the two ends of the bundle 2 are respectively fitted onto the two positioning posts 13 through the positioning holes 14, the two ends of the bundle 2 are respectively located in the two positioning grooves 22.
[0093] With this structural design, by setting the positioning piece 15, after the positioning post 13 is inserted into both ends of the bundle 2, the ends of the bundle 2 can be inserted into the positioning groove 22 formed between the positioning piece 15 and the mounting groove 12, thereby preventing the ends of the bundle 2 from lifting up before the second clamp 5 and the first clamp 4 are fixedly installed, and facilitating the replacement of other components at the same time.
[0094] Example 6:
[0095] This embodiment provides a detachable belt, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0096] Furthermore, the fixing component includes:
[0097] The cover plate 16 is provided with an opening at the upper end of the third mounting cavity 8. The cover plate 16 is rotatably disposed in the opening and is used to cover the opening of the third mounting cavity 8.
[0098] Fixing pin 17: Several fixing pins 17 are fixedly provided at the lower end of the cover plate 16, and the fixing pins 17 are located in the third mounting cavity 8;
[0099] When the cover plate 16 is rotated upward to open, the fixing pin 17 will leave the third mounting cavity 8. The side of the cover plate 16 away from the mounting groove 12 is rotatably connected to the first clamp 4, and the fixing pin 17 is also located on the side of the cover plate 16 away from the mounting groove 12.
[0100] In this technical solution, when the belt body 1 needs to be installed, the cover plate 16 is opened, so that the fixing pin 17 leaves the third mounting cavity 8 as the cover plate 16 rotates. Then, one end of the belt body 1 is inserted into the third mounting cavity 8, and then the cover plate 16 is rotated to close, so that the fixing pin 17 returns to the third mounting cavity 8 as the cover plate 16 rotates, so that the fixing pin 17 is inserted into the belt body 1, thereby fixing the belt body 1.
[0101] When it is necessary to disassemble the belt body 1, open the cover plate 16 so that the fixing pin 17 leaves the third mounting cavity 8 as the cover plate 16 rotates, thereby releasing the fixing pin 17 from the belt body 1, and the belt body 1 can be taken out.
[0102] When the belt body 1 is inserted, it is inserted into the third mounting cavity 8 from the side of the first clamp 4 away from the mounting groove 12. In actual use, if the belt body 1 is subjected to a force that separates it from the first clamp 4 (a force that pulls the belt body 1 out of the third mounting cavity 8), the force will be transmitted to the fixing pin 17. The fixing pin 17 will then transmit the force to the cover plate 16, giving the fixing pin 17 the force to drive the cover plate 16 to rotate downward. The cover plate 16 is placed over the opening of the third mounting cavity 8, preventing the cover plate 16 from rotating downward. Therefore, when the belt body 1 is subjected to a force that separates it from the first clamp 4, it will not separate from the third mounting cavity 8, nor will it cause the fixing pin 17 to move and loosen.
[0103] This structural design, with the addition of a fixing component, makes the disassembly or installation of the belt body 1 convenient and quick, and also prevents the belt body 1 from detaching from the third mounting cavity 8 when under stress, resulting in a better fixing effect while ensuring quick fixation.
[0104] Example 7:
[0105] This embodiment provides a detachable belt, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0106] Furthermore, it also includes:
[0107] The opening and closing slot 18 is formed on the second clamping seat 5;
[0108] Wherein, after the second clamp 5 and the first clamp 4 are fixedly connected by screws, the opening and closing groove 18 of the second clamp 5 corresponds to the side of the cover plate 16 near the mounting groove 12.
[0109] With this structural design, by setting the opening and closing groove 18, when it is necessary to open the cover plate 16, it is convenient to apply force to one end of the cover plate 16 through the opening and closing groove 18, so as to rotate and open the cover plate 16.
[0110] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features described in this application specification can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
