Description

Technical Field

[0001] This utility model relates to the field of fiber optic operation and maintenance technology, and more specifically, to a manual fiber clamp. Background Technology

[0002] Fiber optic identification devices are used in the routine maintenance of optical fibers. These devices can quickly and accurately identify fiber optic lines without cutting the fiber or interrupting communication, determining whether an optical signal is passing through the fiber, its direction, and the fiber's installation and cabling. Fiber optic identification devices are also used for fiber optic fault recovery and service identification. The identification principle of fiber optic identification devices mainly utilizes the macro-bending effect, that is, by bending the target fiber, the transmitted optical signal in the target fiber is leaked. The detector in the fiber optic identification device detects the leaked optical signal, thereby identifying and detecting the fiber. Compared to manually bending fibers, using tools to bend fibers has significant advantages. Currently, existing fiber clamping tools rely on push buttons for control. During operation, the operator needs to manually move the control button to fix the fiber and thus bend it. This control process requires not releasing the button, and fixing the fiber relies on the operator's feel, which can easily damage the fiber. Furthermore, different adapters need to be selected according to the thickness of the fiber when clamping, which brings great inconvenience in practical use. Utility Model Content

[0003] The present invention aims to overcome at least one defect (deficiency) of the prior art and provide a manual fiber clamp that can both bend optical fibers and save effort.

[0004] The technical solution adopted by this utility model is to propose a manual fiber clamp, which includes an upper cover and a base; the upper cover and the base are connected to form a shell, and the shell also includes a sliding part and a pressing control part disposed inside the shell. The pressing control part is provided with a control end extending from the inside of the shell to the outside of the upper cover and having a pressing space; the front end of the base is provided with a front extension, which extends forward relative to the front end of the upper cover. The front extension is provided with a front stop, and the front stop, the front extension, and the front end face of the upper cover together form a receiving groove for placing optical fibers; the upper cover is provided with a front opening, and the pressing control part drives the sliding part to slide back and forth relative to the front opening. The front end of the sliding part is provided with a first clamping end, and the inner wall of the receiving groove is provided with a second clamping end corresponding to the first clamping end; the pressing control part is movably connected to the sliding part so that the first clamping end and the second clamping end cooperate to clamp and bend the optical fiber.

[0005] In this solution, the manual fiber clamp utilizes a labor-saving pressing control structure and a receiving groove with a certain capacity to clamp and bend various types of optical fibers without needing to replace multiple fiber clamping heads.

[0006] Furthermore, the pressing control part includes a pressing member and a pressing member. The first end of the pressing member extends from the inside of the housing to the outside of the upper cover to form the control end. The second end of the pressing member is limited to the inner wall of the upper cover. The first end of the pressing member is movably connected to the middle of the pressing member, and the second end of the pressing member is movably connected to the sliding part.

[0007] In this solution, the pusher and the pressing member together form a pressing control unit to achieve sliding control of the sliding part. The control end of the pressing control unit is one end of the pusher, which is the first end, and the second end of the pusher is limited to the inner wall of the upper cover. One section of the pressing member is connected to the middle of the pusher, which is the second end, and the second end of the pressing member is movably connected to the sliding part.

[0008] Furthermore, a first through hole is provided in the middle of the pressing member, and the first end of the pressing member is movably connected to the middle of the pressing member through a first connecting shaft passing through the first through hole.

[0009] In this design, the first end of the pressing member and the pressing member are connected by a first connecting shaft, and their contact connection is located in the middle of the pressing member, which facilitates the formation of a lever structure with driving effect.

[0010] Furthermore, the sliding part is provided with a second through hole, and the second end of the pressure member is movably connected to the sliding part through a second connecting shaft passing through the second through hole.

[0011] In this solution, the sliding part is movably connected to the second end of the pressing member, and the connection between the sliding part and the pressing member and the movable part is achieved by relying on the connection between the pressing member and the movable part.

[0012] Furthermore, the second end of the pusher is provided with limiting portions on both sides, and the inner wall of the upper cover is provided with limiting grooves that cooperate with the limiting portions, and the limiting portions are accommodated in the corresponding limiting grooves.

[0013] In this solution, the two ends of the pusher are set as a first end and a second end. The first end of the pusher is a control end, and the second end of the pusher is a limiting end. The control end is the start switch of the pressing control part, and the limiting end is a necessary means to realize the cooperation of the pusher and the pressing part. The limiting groove can fix the limiting part.

[0014] Furthermore, the upper surface of the sliding part is provided with guide groove sections on the left and right sides respectively, which abut against the limiting part, and the sliding part slides relative to the limiting part along the length direction of the guide groove section.

[0015] In this solution, the guide groove section restricts the sliding direction of the sliding part and enables the pressing and pressing of the pusher and the pressure member. The guide groove section is located on the upper surface of the middle part of the sliding block. By limiting one end of the pusher, it ensures that the pressure member drives the sliding block to slide along the direction of the guide groove section without deviation or drift.

[0016] Furthermore, the sliding part is provided with an elastic element and a fixing element. The first end of the elastic element is connected to the sliding part, the second end of the elastic element is connected to the fixing element, and the fixing element is connected to the base.

[0017] In this solution, the sliding part is provided with an elastic element and a fixing element. The elastic element and the fixing element are fixedly connected, forming a space for the elastic element to extend and retract, thereby driving the front end of the sliding part to slide.

[0018] Furthermore, the first clamping end is a first groove structure, and the second clamping end is a first protrusion structure that matches the first groove structure;

[0019] Alternatively, the first clamping end is a second protruding structure, and the second clamping end is a second groove structure that matches the second protruding structure.

[0020] In this solution, the front end of the sliding part is a first clamping end, which is configured as a concave arc-shaped structure with obvious protrusions on the left and right sides. The second clamping end is an outward protrusion structure that matches the first clamping end. The outward protrusion structure can be triangular. The second clamping end is located on the top of the base. The first clamping end and the second clamping end can clamp and bend the optical fiber due to their outward and concave structures. The first clamping end can also be a second protrusion structure, and the second clamping end is a second groove structure that matches the second protrusion structure. The second protrusion structure and the second groove structure form a clamping component that can clamp and bend the optical fiber.

[0021] Furthermore, the base is provided with the front extension, the front stop and the rear base. The front extension and the front stop form a U-shaped part with an opening facing the rear base. The first end of the U-shaped part is connected to the rear base to form an integrated structure. The second end of the U-shaped part and the front end face of the upper cover together form the receiving groove.

[0022] In this design, the base not only supports the overall structure, but also includes a front extension and a front stop forming a U-shaped portion and a rear base portion with openings facing the rear base portion. The other end of the U-shaped portion and the front end face of the upper cover together form a receiving groove. The internal space of the receiving groove is provided with a first clamping part or a second clamping part for clamping. The front end of the upper cover is also provided with a front opening through which the optical fiber enters. The clamping component in the receiving groove acts on the optical fiber. The base is also provided with a limiting area for limiting the slider portion. The limiting area fixes the slider portion and ensures the stability of clamping.

[0023] Furthermore, the upper cover is provided with an upward protrusion, and the protrusion is provided with an opening segment extending forward and backward; the control end extends from the inside of the housing to the outside of the upper cover through the opening segment, and forms a pressing space based on the opening segment.

[0024] In this design, the top cover not only has a shell that protects the internal structure, but also has an opening section that accommodates the control end of the pressing control unit. The opening section facilitates the control of the pressing control unit and also helps the control end of the pressing control unit to reset. It also limits the pressing degree of the control end of the pressing control unit. The control end moves within the space of the opening section. The top cover is indispensable to the entire manual fiber clamp.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: the manual fiber clamp achieves the clamping and bending of the optical fiber by pressing control, and it does not require frequent replacement of the fiber clamp to clamp and bend various optical fibers. During the clamping and bending process, it does not require manual pressing of the fiber clamp, which can reduce the workload of fiber clamping and reduce labor costs. Attached Figure Description

[0035] Example 1

[0036] like Figure 1 and Figure 2 ,as well as Figure 3As shown, this embodiment proposes a manual fiber clamp, which includes an upper cover 10 and a base 20; the upper cover 10 and the base 20 are connected to form a housing, and the housing also includes a sliding part 40 and a pressing control part 30 disposed inside the housing. The pressing control part 30 is provided with a control end extending from the inside of the housing to the outside of the upper cover 10 and having a pressing space; the front end of the base 20 is provided with a front extension, which extends forward relative to the front end of the upper cover 10, and the front extension is provided with a front stop. The front stop, the front extension, and the upper cover 20 are connected together. The front end face of the cover 10 together forms a receiving groove 50, which is used to place optical fibers. The upper cover has a front opening 1. The pressing control part 30 drives the sliding part 40 to slide back and forth relative to the front opening 1. The front end of the sliding part 40 is provided with a first clamping end 7. The inner wall of the receiving groove 50 is provided with a second clamping end corresponding to the first clamping end 7. The pressing control part 30 is movably connected to the sliding part 40 so that the first clamping end 7 and the second clamping end cooperate with each other to clamp and bend the optical fiber.

[0037] In this solution, when the manual fiber clamp is in operation, pressing the control end of the pressing control part 30 outside the housing causes the sliding part 40 to slide backward inside the housing. At this time, the first clamping end 7 and the second clamping end separate. The first clamping end 7 is located at the front end of the sliding part 40, and the second clamping end is located on the inner wall of the U-shaped part 13 with the front extension of the base 20 and the front stop forming an opening facing the rear base part 14. The optical fiber can enter the receiving groove 50 through the front opening 1. At this time, releasing the control end causes the sliding part 40 to return to its original position and slide forward, so that the first clamping end 7 and the second clamping end cooperate to clamp and bend the optical fiber. The entire structure utilizes the labor-saving pressing control part 30 and the receiving groove 50 with a certain capacity to achieve clamping and bending of various optical fibers without changing various fiber clamping heads.

[0038] Optionally, the pressing control part includes a pressing member 2 and a pressing member 6. The first end of the pressing member 2 extends from the inside of the housing to the outside of the upper cover 10 to form the control end. The second end of the pressing member 2 is limited to the inner wall of the upper cover 10. The first end of the pressing member 6 is movably connected to the middle of the pressing member 2, and the second end of the pressing member 6 is movably connected to the sliding part 40.

[0039] In a specific implementation, the two opposite ends of the press member 2 are respectively set as a first end and a second end. The first end of the press member 2 is provided with the control end, and the second end is limited and fixed. In a preferred embodiment, the pressing member 6 is an I-shaped component. The two opposite ends of the pressing member 6 are respectively set as a first end and a second end. One end of the pressing member 6 is movably connected to the middle of the press member 2, and the other end of the pressing member 6 is movably connected to the sliding part 40. The press member 2 and the pressing member 6 are movably connected to form a control structure. Pressing the control end of the press member 2 will drive the pressing member 6 to move backward. Since the pressing member 6 is movably connected to the sliding part 40, while the press member 2 drives the pressing member 6 to move backward, it will also drive the sliding part 40 to slide. The press member 2 and the pressing member 6 form a pressing control unit to realize the sliding control of the sliding part 40.

[0040] Optionally, the middle part of the pressing member 2 is provided with a first through hole, and the first end of the pressing member 6 is movably connected to the middle part of the pressing member 2 through a first connecting shaft 4 passing through the first through hole.

[0041] In specific implementation, the pusher 2 and the pressure member 6 are connected by the first connecting shaft 4, and the connection position of the two is located in the middle of the pusher 2, which facilitates the formation of a lever structure with driving effect. The connection method includes, but is not limited to, this.

[0042] Optionally, the sliding part 40 is provided with a second through hole 11, and the second end of the pressure member 6 is movably connected to the sliding part 40 through a second connecting shaft 3 passing through the second through hole 11.

[0043] In specific implementation, the sliding part 40 and the pressing member 6 are movably connected through the second connecting shaft 3. The connection with the pressing control part 30 is achieved by relying on the connection between the pressing member 6 and the sliding part 40. The connection method includes, but is not limited to, this.

[0044] Optionally, the second end of the pusher 2 is provided with limiting parts 5 on both sides, and the inner wall of the upper cover 10 is provided with limiting grooves that cooperate with the limiting parts 5, and the limiting parts 5 are accommodated in the corresponding limiting grooves.

[0045] In specific implementation, the two ends of the pusher 2 are a control end and a limiting part 5, respectively. The control end is the start switch of the press control part 30. The limiting part 5 is a necessary means to realize the cooperation of the pusher 2 and the pressing part 6. The limiting groove can fix the limiting part 5.

[0046] Optionally, the upper surface of the sliding part 40 is provided with guide groove sections 8 on the left and right sides respectively, which abut against the limiting part 5, and the sliding part 40 slides relative to the limiting part 5 based on the length direction of the guide groove section 8.

[0047] In specific implementation, the guide groove section 8 serves to limit the sliding direction of the sliding part 40 and is a necessary means to achieve the cooperation and pressing of the pusher 2 and the pressing member 6. The guide groove section 8 is set on the upper surface of the sliding part 40. By limiting the pusher 2 with the limiting part 5, it ensures that the pressing member 6 drives the sliding part 40 to slide along the direction of the guide groove section 8 without deviation or drift. The guide groove section 8 is not limited.

[0048] Optionally, the sliding part 40 is provided with an elastic element 9 and a fixing element 12. The first end of the elastic element 9 is connected to the sliding part 40, and the second end of the elastic element 9 is connected to the fixing element 12. The fixing element 12 is connected to the base 20.

[0049] In a specific implementation, the sliding part 40 is provided with an elastic element 9 and a fixing element 12. The elastic element 9 can be a spring. The elastic element 9 is fixedly connected to the fixing element 12. A space is formed between the sliding part 40 and the fixing element 12 for the elastic element 9 to deform. The elastic element 9 deforms in the space, causing the front end of the sliding part 40 to slide and produce the effect of the sliding part 40 extending and retracting back and forth.

[0050] In specific operation, when the control end is pressed, the limiting part 5 of the pressing part 2 is limited on the upper cover 10, so that the pressing force of the control end acts on the pressing part 6. The pressing part 6 pushes the sliding part 40 to slide backward. At this time, the front end of the sliding part 40 is squeezed by the elastic part 9 of the sliding part 40 and slides backward. The optical fiber is put into the receiving groove 50 through the front opening 1. At this time, the control end is released, the elastic part 9 is reset and pushes the front end of the sliding part 40 to slide forward. The clamping and bending of the optical fiber is completed by the cooperation of the first clamping end 7 and the second clamping end.

[0051] Optionally, the first clamping end 7 is a first groove structure, and the second clamping end is a first protrusion structure that matches the first groove structure;

[0052] Alternatively, the first clamping end 7 may be a second protruding structure, and the second clamping end may be a second groove structure that matches the second protruding structure.

[0053] In a specific implementation, the front end of the sliding part 40 is the first clamping end 7, which is configured as a concave arc structure, so that the front end of the sliding part 40 has obvious protrusions on both the left and right sides. The second clamping end is an outward protrusion structure that matches the first clamping end 7. The outward protrusion structure can be a triangle with rounded corners. The second clamping end is located at the front end of the base 20. The first clamping end 7 and the second clamping end can clamp and bend the optical fiber due to their outward and concave structures.

[0054] In one optional embodiment, the first clamping end 7 may also be a second protrusion structure, and the second clamping end is a second groove structure that matches the second protrusion structure. The second protrusion structure and the second groove structure form a clamping component that can clamp and bend the optical fiber. The specific form of the clamping component includes, but is not limited to, this.

[0055] Optionally, the base is provided with the front extension, the front stop and the rear base. The front extension and the front stop form a U-shaped part 13 with an opening facing the rear base 14. The first end of the U-shaped part 13 is connected to the rear base 14 to form an integrated structure. The second end of the U-shaped part 13 and the front end face of the upper cover 10 together form the receiving groove 50.

[0056] In specific implementation, the base 20 not only serves to support the overall structure, but also includes a rear base portion 14 and a front extension portion and a front stop portion forming a U-shaped portion 13 with an opening facing the rear base portion 14. The two ends of the U-shaped portion are respectively designated as a first end and a second end. The first end of the U-shaped portion 13 is connected to the rear base portion 14 to form an integrated structure. The second end of the U-shaped portion 13 forms a receiving groove 50 with the front end face of the upper cover 10. The internal space of the receiving groove 50 is provided with a second clamping end for clamping. The upper cover 10 is provided with a front opening 1. The optical fiber enters the receiving groove 50 through the front opening 1. The clamping part in the receiving groove 50 acts on the optical fiber. The base 20 is also provided with a limiting area 15 for limiting the sliding portion 40. The limiting area 15 limits the forward and backward sliding of the sliding portion 40 to ensure the stability of clamping.

[0057] Optionally, the upper cover 10 is provided with an upward protrusion 17, and the protrusion is provided with an opening segment 16 extending forward and backward; the control end extends from the inside of the housing to the outside of the upper cover 10 through the opening segment 16, and forms a pressing space based on the opening segment 16.

[0058] In specific implementation, the upper cover 10 not only has a shell to protect the internal structure, but also has an opening section 16 to accommodate the control end of the pressing control unit 30. The opening section 16 facilitates the control of the pressing control unit 30 and also helps the control end of the pressing control unit 30 to reset. It also limits the pressing degree of the control end of the pressing control unit 30. The control end moves within the space of the opening section 16, and the position and size of the opening section 16 are not specifically limited.

[0059] Further explanation of the present invention: In this invention, the fiber optic clamp is manually controlled to clamp and bend the fiber. First, the sliding part 40 is driven to slide along the elastic member 9 by the pressing control unit 30. Simultaneously, the front end of the sliding part 40 slides backward, opening the internal receiving groove 50 of the front opening 1 of the fiber optic clamp facing the top cover opening. The fiber is then placed through the front opening 1 into the internal receiving groove 50 of the fiber optic clamp, causing the control end of the pressing control unit 30 to reset. At this point, the internal structure of the pressing control unit 30 returns to its pre-press position due to its limiting and fixing function, thereby driving the front end of the sliding part 40 along the elastic member. 9. Extending forward, the front end of the sliding part 40 is provided with a first clamping end 7, and the front end of the base 20 is provided with a second clamping end that matches the front end of the sliding part 7. When the front end of the sliding part 40 extends forward and approaches the front end of the base 20, the clamping parts of the two work together to clamp and bend the optical fiber placed in the internal receiving groove 50 of the base 20. During the entire operation, after manually controlling the fiber clamping, the fiber clamp will clamp the optical fiber due to the reset of the pressing control part 30. It is not necessary to hold and press continuously for bending. At the same time, the clamping part has high adaptability and does not require frequent replacement of different types of fiber clamping heads. The manual fiber clamp is not only labor-saving but also adaptable to various fiber clamping tasks in daily life.
