Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and in particular to an optical fiber cutter that does not require tools to manually adjust the blade height. Background Technology

[0002] In the construction of communication and information engineering projects, optical cables are typically laid. After the optical cables are laid, each cable needs to be connected to form a long-distance optical cable. The connection of the optical cable joint is completed by using a fiber optic fusion splicer to fuse each optical fiber in one cable to each optical fiber in the next cable. Before fiber optic splicing, the optical fiber must be cut to ensure that the cut surface of the optical fiber used for splicing is intact and clean. This process is an indispensable step in the fiber optic fusion splicing operation. When cutting the optical fiber, the relative position of the optical fiber and the blade must be adjusted before cutting. However, currently, the blade of the fiber optic cleaver needs to be fixed and adjusted with a screwdriver. When using a screwdriver to turn the screw to move the blade, it is difficult to control the height of the blade movement. This inconvenience can easily affect the quality of fiber optic cutting. Utility Model Content

[0003] In view of the problem that in the prior art, adjusting the blade height of a fiber optic cutter requires loosening screws with a screwdriver and is difficult to control the height of the blade movement, this utility model proposes a solution.

[0004] To achieve the above objectives, this utility model provides a fiber optic cutter that allows for manual adjustment of the blade height without the need for tools, comprising:

[0005] The base has a receiving space inside, and a cutting component is provided inside the receiving space. The surface of the base has an optical fiber groove and an opening for receiving optical fibers. The opening is connected to the receiving space and is used to allow the working end of the cutting component to protrude.

[0006] A fixing plate is disposed within the accommodating space and fixedly connected to the inner wall of the base. The fixing plate has a through hole, through which a bolt is connected. The bolt passes through the through hole and is threaded to one end of the cutting assembly to adjust the height of the cutting assembly protruding from the opening. The side of the bolt that abuts against the through hole forms at least two recessed areas, which are arranged circumferentially around the surface. An elastic element is provided on the side of the fixing plate facing the recessed areas. The elastic element abuts against a protrusion adapted to the recessed areas in the middle of the recessed areas.

[0007] As an improvement of this utility model, an elastic connecting component is provided in the accommodating space, and a slot is provided on the surface of the cutting component. The opening direction of the slot tends to the moving direction of the cutting component, and its length is not less than the maximum moving height of the cutting component. The elastic connecting component passes through the slot and is connected to the fixing plate.

[0008] As an improvement of this utility model, the recessed area is arc-shaped, and the end of the protrusion that abuts against the recessed area is an arc end to facilitate the abutment and sliding of the protrusion and the recessed area.

[0009] As an improvement of this utility model, the cutting assembly includes a blade holder and a blade fixed on the blade holder. The blade passes through an opening to cut optical fibers. The blade holder is connected to a connecting post with a threaded hole. The connecting post is threadedly connected to a bolt to adjust the height of the blade protruding from the opening.

[0010] As an improvement of this utility model, a first spring is provided at the end of the blade holder away from the bolt, and the first spring abuts against the blade holder and the fixing plate.

[0011] As an improvement of this utility model, the base surface is provided with a fiber outlet communicating with the accommodating space, and the fiber outlet is detachably connected to a fiber take-up box.

[0012] As an improvement of this utility model, the cutting component is further provided with a gasket, which is located between the elastic connecting component and the cutting component and abuts against the elastic connecting component and the cutting component.

[0013] As an improvement of this utility model, the elastic connection assembly includes a screw and a second spring sleeved on the screw. One end of the second spring abuts against the head end face of the screw, and the other end abuts against the washer. The fixing plate is provided with a threaded hole, and the screw is threadedly connected to the threaded hole.

[0014] As an improvement of this utility model, the base is provided with an installation port that connects to the accommodating space and a cover plate that is detachably connected to the installation port. The installation port is located on the side opposite to the bolt so that the bolt is exposed.

[0015] As an improvement of this utility model, the bolt is provided with a groove, one end of which extends to the bottom of the through hole, and the other end extends to the area between the fixing plate and the connecting column. The accommodating space is provided with a retaining ring that matches the width of the groove and has an outer diameter larger than the diameter of the through hole. The retaining ring engages with the groove to prevent the bolt from shifting relative to the fixing plate.

[0016] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model provides a fiber optic cutter that does not require tools for manual adjustment of the blade height. It includes a base and a fixing plate. The base has a receiving space, and a cutting component is located within the receiving space. The surface of the base has fiber optic grooves and openings for receiving optical fibers. The openings communicate with the receiving space and allow the working end of the cutting component to protrude. The fixing plate is located within the receiving space and is fixedly connected to the inner wall of the base. The fixing plate has a through hole, through which a bolt is connected. The bolt passes through the through hole and is threadedly connected to one end of the cutting component to adjust the height of the cutting component protruding from the opening.

[0034] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0035] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0036] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0037] Please see Figure 1-11This utility model discloses a fiber optic cutter that allows for manual blade height adjustment without tools. It includes a base 1, a fixing plate 3, and an elastic connecting assembly 5. The base 1 has a receiving space containing a cutting assembly 2. The surface of the base 1 has a fiber groove 11 and an opening 12 for accommodating the fiber optic cable. The opening 12 communicates with the receiving space and allows the working end of the cutting assembly 2 to protrude. The fixing plate 3 is disposed within the receiving space and fixedly connected to the inner wall of the base 1. The fixing plate 3 has a through hole 31, through which a bolt 4 is connected. The bolt 4 passes through the through hole 31 and is threadedly connected to one end of the cutting assembly 2 to adjust the cutting assembly 2. The height of the protrusion opening 12; the side of the bolt 4 that abuts against the through hole 31 forms at least two recessed areas 41, the recessed areas 41 are arranged circumferentially around the surface, the side of the fixing plate 3 facing the recessed areas 41 is provided with an elastic element, the elastic element abuts against the middle of the recessed areas 41 with a protrusion 322 that matches the recessed areas 41; the elastic connecting component 5 is arranged in the accommodating space, the surface of the cutting component 2 is provided with a slot 25, the opening direction of the slot 25 tends to the moving direction of the cutting component 2, and the length of the slot 25 is not less than the maximum moving height of the cutting component 2, the elastic connecting component 5 passes through the slot 25 and is connected to the fixing plate 3.

[0038] In this embodiment, the cutting assembly 2 includes a blade holder 21 and a blade 22 fixed on the blade holder 21. The blade 22 passes through the opening 12 to cut the optical fiber. The blade holder 21 is connected to a connecting post 23 with a threaded hole. The connecting post 23 is threadedly connected to a bolt 4 to adjust the height of the blade 22. Specifically, the user does not need to use tools; simply turning the bolt 4 clockwise or counterclockwise will cause the connecting post 23 to move up and down due to the transmission action of the thread, thereby moving the blade 22 and the blade holder 21 up and down as a whole, thus adjusting the height of the blade 22.

[0039] More specifically, the blade holder 21 is fixedly provided with a positioning post 27 perpendicular to the bolt 4. The blade holder 21 is perpendicularly connected to the connecting post 23 through the positioning post 27, ensuring that the connecting post 23 and the bolt 4 always remain perpendicular. In addition, the connecting post 23 and the positioning post 27 are connected by a gap, allowing the connecting post 23 to be movably connected to the positioning post 27.

[0040] Preferably, a first spring 26 is provided at the end of the blade holder 21 away from the bolt 4. The first spring 26 abuts against the blade holder 21 and the fixing plate 3. The first spring 26 provides downward pressure to the blade holder 21 to stabilize the height of the blade holder 21, thereby ensuring the stability of the height of the blade 22.

[0041] In this embodiment, when adjusting the height of the cutting assembly 2, by rotating the bolt 4, the protrusion 322 contacts the bolt 4 at different positions under the elastic force of the elastic element, resulting in a slight collision. This allows the user to perceive and accurately fix the change in the height of the blade 22. Furthermore, when the bolt 4 is not rotated, the protrusion 322 abuts against the recessed area 41, preventing accidental contact and displacement of the bolt 4, thus avoiding inaccurate height of the blade 22 and stabilizing the bolt 4.

[0042] More specifically, the recessed area 41 of the bolt 4 is arc-shaped, and the end of the protrusion 322 that abuts against the recessed area 41 is an arc-shaped end to facilitate the abutment and sliding of the protrusion 322 and the recessed area 41. The elastic element is a third spring 321, one end of which abuts against the fixing plate 3, and the other end abuts against the protrusion 322. The arc-shaped end of the protrusion 322 is adapted to the arc-shaped recessed area 41 to ensure that when the bolt 4 rotates, the arc-shaped end of the protrusion 322 and the recessed area 41 can smoothly and unobstructedly abut and slide apart.

[0043] The length of the slot 25 is set in the direction of movement of the cutting component 2, and its length is not less than the maximum moving height of the cutting component 2. This ensures that when the cutting component 2 is adjusted in height, the elastic connecting component 5 is restricted to two extreme positions within the slot 25, thereby limiting the range of movement of the cutting component 2. The elastic connecting component 5 passes through the slot 25 and is connected to the fixing plate 3, so that no matter how the height of the blade holder 21 is adjusted, the blade holder 21 can be stably attached to the fixing plate 3, preventing the blade holder 21 from shaking and significantly improving the stability of the equipment.

[0044] Specifically, the cutting assembly 2 is further provided with a washer 24, which is located between the elastic connecting assembly 5 and the cutting assembly 2 and abuts against both. More specifically, the elastic connecting assembly 5 includes a screw 51 and a second spring 52 sleeved on the screw 51. One end of the second spring 52 abuts against the head face of the screw 51, and the other end abuts against the washer 24. The fixing plate 3 is provided with a threaded hole, and the screw 51 is threadedly connected to the threaded hole. The second spring 52 is provided between the screw 51 and the cutting assembly 2 to ensure that the blade holder 21 can be stably attached to the fixing plate 3 regardless of how its height is adjusted. The function of the washer 24 is to prevent the second spring 52 from directly contacting the wall surface of the cutting assembly 2, thus avoiding damage.

[0045] In this embodiment, the base 1 has a fiber outlet 16 communicating with the accommodating space on its surface. The fiber outlet 16 is detachably connected to a fiber take-up box 17. Specifically, the two opposite walls of the fiber outlet 16 are respectively provided with a first latch 161 and a second latch 162. The fiber take-up box 17 is provided with a first latch 171 that engages with the first latch 161 at the position corresponding to the first latch 161, and a second latch 172 that engages with the second latch 162 at the position corresponding to the second latch 162. The first latch 171 is provided with a protrusion 173 that abuts against the surface of the base 1. The user does not need to use tools. He only needs to press the protrusion 173 outward to flip it out so that the first latch 171 disengages from the first latch 161, thereby facilitating the disassembly of the fiber take-up box 17 and the emptying of the optical fiber in the accommodating space.

[0046] In this embodiment, the side of the fixing plate 3 opposite to the recessed area 41 is provided with a mounting hole 33. The elastic element is accommodated in the mounting hole 33, and the diameter of the mounting hole 33 away from the bolt 4 is smaller than the width of the elastic element. The diameter of the mounting hole 33 away from the bolt 4 should be smaller than the width of the elastic element to effectively provide the required tensile force for the elastic element.

[0047] In this embodiment, the side of the bolt 4 away from the fixing plate 3 is provided with a protruding structure 42 to facilitate the rotation of the bolt 4. The shape of the protruding structure 42 is preferably a straight line, but it can also be a cross shape, etc.

[0048] In this embodiment, the base 1 is provided with an installation port 13 communicating with the accommodating space and a cover plate 14 detachably connected to the installation port 13. The installation port 13 is located on the side facing the protruding structure 42 of the bolt 4 so as to expose the protruding structure 42 and allow rotation of the protruding structure 42. Specifically, the two opposite walls of the installation port 13 are respectively provided with snap-fit ​​interfaces 131, and the cover plate 14 is provided with snap-fit ​​blocks 141 at the positions corresponding to the snap-fit ​​interfaces 131. The installation port 13 and the cover plate 14 are snap-fit ​​connected to the snap-fit ​​blocks 141 through the snap-fit ​​interfaces 131. The snap-fit ​​connection between the installation port 13 and the cover plate 14 facilitates the removal of the cover plate 14. After removal, the protruding structure 42 of the bolt 4 is exposed, and the protruding structure 42 can be rotated to adjust the height of the blade 22. An operating part 132 is provided on the surface of the base 1 adjacent to one of the snap-fit ​​interfaces 131, which is convenient for the user to hold. The shape of the operating part 132 is designed to be an arc shape that conforms to the ergonomic principle so that the user can easily and firmly hold the operating part 132, thereby conveniently opening the cover plate 14. The disassembly method is similar to that for disassembling the remote control battery cover.

[0049] In this embodiment, the bolt 4 is provided with a groove 43, one end of which extends to the bottom of the through hole 31, and the other end extends to the area between the fixing plate 3 and the connecting post 23. A retaining ring 15, which is adapted to the width of the groove 43 and has an outer diameter larger than the diameter of the through hole 31, is provided in the accommodating space. The retaining ring 15 engages with the groove 43 to prevent the bolt 4 from shifting relative to the fixing plate 3. By embedding the retaining ring 15 into the groove 43 to form a retaining fit, the possible displacement of the bolt 4 relative to the fixing plate 3 is effectively limited. This structural design ensures the rotation of the bolt 4 during adjustment and provides reliable positioning after adjustment, preventing accidental displacement due to vibration or external force.

[0050] The working principle of this utility model is as follows:

[0051] When adjusting the height of the blade 22 using this device, the cover plate 14 must first be removed. After removing the cover plate 14, the protruding structure 42 of the bolt 4 will be exposed. By rotating the protruding structure 42, the connecting post 23 threaded to the bolt 4 will drive the blade 22 and the blade holder 21 to move. Since the side of the bolt 4 connected to the fixing plate 3 has a recessed area 41, and the fixing plate 3 has a protrusion 322 at the position corresponding to the recessed area 41 that abuts against the third spring 321, the protrusion 322 collides with the bolt 4 under the action of the elastic force, allowing the user to perceive the rotation position and thus understand the height of the blade 22. The bolt 4 passes through the slot 25 of the cutting assembly 2 and is connected to the fixing plate 3. A second spring 52 is provided between the bolt 4 and the washer 24 of the cutting assembly 2 to ensure that the bolt 4 stabilizes its position while pushing the cutting assembly 2.

[0052] The advantages of this utility model are:

[0053] This invention utilizes a bolt-and-elastic element contact design, allowing the elastic element to flexibly switch its contact position between the recessed area and the flat surface during bolt rotation. This design not only facilitates adjustment of the cutting assembly's height but also enables precise control and positioning of height movement. Furthermore, the contact between the elastic element and the recessed area prevents accidental bolt contact that could lead to inaccurate blade height.

[0054] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
