Technical Field

[0001] This utility model relates to fiber optic cleavers, and more particularly to a fiber optic cleaver based on a slide bar. Background Technology

[0002] The slider of a fiber optic cleaver typically slides back and forth via a slide rail. For a related structure, please refer to Chinese Patent Publication No. CN207380284U, entitled "An Adapter Fiber Optic Cleaver." The slide rail assembly used therein is based on a structure where a groove and a slide rail cooperate. This type of slide rail assembly is relatively complex and has a high application cost. With the increasing market demand for simplified and low-cost fiber optic cleavers, traditional slide rail assemblies are not only space-consuming but also expensive. Furthermore, to achieve the connection between the slide rail assembly and the cleaver head support, the existing fiber optic cleaver's slide rail assembly is usually exposed. During use, small fiber optic ends are prone to entering the groove, affecting cutting and making cleaning difficult. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fiber optic cleaver based on a slide bar that is simple in structure, lower in cost, and easy to clean and maintain, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A fiber optic cleaver based on a sliding rod includes a main housing, a pressure cap, and a slider. The pressure cap covers the top of the main housing and is rotatable relative to the main housing. A receiving opening is provided on one side of the main housing. Two horizontal sliding rods arranged vertically and parallel to each other are fixed on the inner wall of the receiving opening. The slider is disposed in the receiving opening and has a cutting head extending upwards from the main housing. Two upper and lower sliding blocks are provided on the side of the slider facing the horizontal sliding rods. The two horizontal sliding rods pass through the two sliding blocks respectively and slide in cooperation with the sliding blocks. A spring is sleeved on the horizontal sliding rod and is used to drive the slider to slide out of the receiving opening.

[0006] Preferably, a copper sleeve is embedded in the slide block, and the transverse slide rod passes through the copper sleeve and the two slide in cooperation.

[0007] Preferably, the inner wall of the receiving port is provided with a cavity, and two transverse sliding rods are fixed in the cavity.

The through holes and the latches are aligned one by one, and the front and rear ends of the transverse slide rod are respectively locked in the through holes and the latches.

[0009] Preferably, the rear sidewall of the cavity has two first transverse grooves extending to the left, and the sidewall of the main housing opposite to the cavity has two second transverse grooves extending to the right. The first transverse grooves and the second transverse grooves correspond one-to-one, and the first transverse grooves and the second transverse grooves are staggered and the junction of the two forms the bayonet.

[0010] Preferably, one end of the pressure cap is hinged to a fixing block, and the fixing block is fixedly connected to the front end of the main housing by two screws.

[0011] Preferably, the main housing has two slots on one side wall facing away from the cavity, and the screw engages with the nut located in the slot.

[0024] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0025] This utility model discloses a fiber optic cleaver based on a slide bar, combined with... Figures 1 to 4 As shown, it includes a main housing 1, a pressure cover 2, and a slider 3. The pressure cover 2 covers the top of the main housing 1 and can be flipped relative to the main housing 1. A receiving opening 10 is provided on one side of the main housing 1. Two horizontal sliding rods 11 are fixed on the inner wall of the receiving opening 10 and are arranged vertically and parallel to each other. The slider 3 is located in the receiving opening 10. The slider 3 is provided with a cutter head 31 extending upwards from the main housing 1. The slider 3 is provided with two upper and lower sliding seats 30 on the side facing the horizontal sliding rods 11. The two horizontal sliding rods 11 pass through the two sliding seats 30 respectively, and the horizontal sliding rods 11 slide in cooperation with the sliding seats 30. A spring 12 is sleeved on the horizontal sliding rods 11. The spring 12 is used to drive the slider 3 to slide out of the receiving opening 10.

[0026] In the above structure, a receiving opening 10 is provided on one side of the main housing 1, and the slider 3 is directly disposed in the receiving opening 10, eliminating the need for a closed chamber within the main housing 1, thus simplifying the structure of the main housing 1. Simultaneously, two parallel horizontal sliding rods 11 are fixed to the inner wall of the receiving opening 10, and correspondingly, two upper and lower sliding seats 30 are provided on one side of the slider 3. The two horizontal sliding rods 11 pass through the two sliding seats 30 respectively. Compared to the existing assemblies using grooves and rails, this invention, based on the sliding cooperation between the horizontal sliding rods 11 and the sliding seats 30, not only simplifies the structure of the rail assembly but also reduces application costs. Furthermore, this invention eliminates the need for grooves, avoiding the situation where small optical fiber ends get stuck in the grooves, thus making it easier to clean and maintain.

[0027] In this embodiment, the spring 12 is clamped between the front sidewall of the receiving port 10 and the front end of the slide block 30.

[0028] In a preferred embodiment, a copper sleeve 32 is embedded in the slide block 30, and the transverse slide rod 11 passes through the copper sleeve 32 and the two are slidably engaged. This embodiment preferably employs a slidable engagement between the copper sleeve 32 and the transverse slide rod 11. Based on the excellent self-lubricating properties of the copper sleeve 32, a smooth and reliable sliding relationship can be ensured.

[0029] In this embodiment, the sliding component is preferably hidden. For details, please refer to [link to relevant documentation]. Figure 3 and Figure 4 The inner wall of the receiving port 10 is provided with a cavity 13, and two transverse slide rods 11 are fixed in the cavity 13. In the above structure, the slide block 30 is sleeved on the outside of the transverse slide rods 11. Under the shielding effect of the slider 3, both the slide block 30 and the transverse slide rods 11 are hidden in the cavity 13, further preventing the cut optical fiber end from entering the cavity 13. This ensures that the slider 3 slides smoothly and facilitates cleaning and maintenance.

[0030] Combination Figures 5 to 8 As shown, in this embodiment, the front sidewall of the cavity 13 is provided with two through holes 14, and the rear sidewall of the cavity 13 is provided with two latches 15, the through holes 14 and the latches 15 are aligned one by one, and the front and rear ends of the transverse slide rod 11 are respectively locked in the through holes 14 and the latches 15.

[0031] During installation, one end of the transverse slide rod 11 is passed through the through hole 14 and pushed into the recess 13 until the end of the transverse slide rod 11 is inserted into the bayonet 15, thereby fixing the transverse slide rod 11 in the recess 13.

[0032] In practical applications, since the bayonet 15 is located on the rear side wall of the cavity 13, and the main housing 1 is formed by injection molding of plastic parts, the bayonet 15, which is located in the recess, does not have space for the mold to move in and out, so it is difficult to injection mold it by direct core pulling. Therefore, in this embodiment, the bayonet 15 is preferably injection molded by staggered slotting. Specifically:

[0033] The rear sidewall of the cavity 13 has two first transverse grooves 16 extending to the left, and the sidewall of the main housing 1 opposite to the cavity 13 has two second transverse grooves 17 extending to the right. The first transverse grooves 16 and second transverse grooves 17 correspond one-to-one, and are staggered, with the junction forming the notch 15. The first transverse grooves 16 and second transverse grooves 17 extend to the left and right respectively, and are located at the same height on the main housing 1 but slightly offset. Figure 6As shown, during injection molding, the first horizontal groove 16 and the second horizontal groove 17 can be injection molded by the molding needles respectively. When the mold is opened, the molding needles on the left and right sides retract synchronously to pull the core. At this time, the bayonet 15 is formed at the junction of the first horizontal groove 16 and the second horizontal groove 17, making the injection molding process simpler.

[0034] As a preferred embodiment, the ends of the first transverse groove 16 and the second transverse groove 17 are both semi-circular, so that the bayonet 15 at the junction of the two is in the shape of a circular hole, which facilitates its tight insertion and matching with the transverse slide bar 11.

[0035] Regarding the preferred flipping method of the pressure cap 2, in this embodiment, combined with Figure 9 and Figure 10 As shown, one end of the pressure cover 2 is hinged to a fixing block 20, and the fixing block 20 is fixedly connected to the front end of the main housing 1 by two screws 21.

[0036] Furthermore, the main housing 1 has two slots 18 on its side wall facing away from the cavity 13, and the screw 21 engages with the nut that is engaged in the slot 18. One function of the slot 18 is to accommodate and conceal the nut, and another function is to engage with the nut to prevent the nut from rotating with the screw 21.

[0037] As a preferred embodiment, a side cover 19 is fixed to the side of the main housing 1 facing away from the recess 13, and the side cover 19 covers the slot 18 and the second transverse groove 17. The side cover 19 primarily serves to conceal the groove, aiming to make the side of the product simple and aesthetically pleasing.

[0038] Based on this, please see Figure 4 and Figure 9 The slider 3 is equipped with a cutter head support 39, and the bottom of the pressure cover 2 is equipped with a vertically movable limiting plate 29. A limiting plate spring is sandwiched between the limiting plate 29 and the pressure cover 2. The limiting plate 29 includes a limiting stop bar 28 extending into the movement space of the cutter head support 39. When the slider 3 is pushed backward, the cutter head support 39 drives the cutting head to cut the optical fiber held between the pressure cover 2 and the main housing 1. After the cutter head support 39 passes the rounded corner, it is engaged with the rear side of the limiting stop bar 28. In this process, the cutting head first completes the optical fiber cutting, and then the cutter head support 39 is engaged and restricted to the rear side of the limiting stop bar 28. At this time, the pressure cover 2 can be opened first, and then the cut optical fiber can be removed. Then, the spring 12 is used to drive the slider 3 to slide forward and reset, thereby ensuring better high-speed cutting of optical fibers.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
