Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
This application has designed an optic fibre cutting knife and upper cover thereof, considers the briquetting fixed setting on the upper cover, drops on the pressure pad or two pressure pads wearing and tearing inhomogeneous backs when dust foreign matter etc. probably lead to having a height difference between two briquetting to make optic fibre can't be compressed tightly, cause the untidy situation of optic fibre cutting. Therefore, this application sets up the briquetting into floating type briquetting, and the elasticity through the spring makes the both ends homoenergetic of each briquetting tightly push down optic fibre, has solved optic fibre and can't be by firm fixed problem in the cutting process.
The application provides in a first aspect an upper cover for an optical fiber cleaver.
For easy understanding, please refer to fig. 2 and 3, in which fig. 2 is a schematic structural diagram of an upper cover of an optical fiber cleaver in an embodiment of the present application, and fig. 3 is a schematic structural diagram of a floating assembly and a pressing block in an embodiment of the present application.
The embodiment of the application provides an upper cover of an optical fiber cutter, which comprises a gland 1, a floating assembly 2, two pressing blocks 3 arranged in parallel and a pressing pad 4 arranged in a pressing pad installation part 31 of the pressing block 3.
The gland 1 is provided with a through hole for the pressure pad installation part 31 to pass through, and the floating assembly 2 comprises 4 groups of connecting pieces 21 and springs 22; the connector 21 includes a head portion and a shaft portion; the rod part sequentially penetrates through the spring 22 and the mounting hole 32 of the pressing block 3 and is fixedly connected with the gland 1; the spring 22 is in compression between the head and the mass 3. It should be noted that the floating assembly 2 in fig. 3 is in an unassembled state, in which the spring 22 is in a natural state and is not compressed, and when the assembly is completed, the spring 22 is in a compressed state, and the top end of the rod portion of the connecting member 21 should be beyond the mounting hole 32 or flush with the mounting hole 32.
Because the connecting piece 21 is fixedly connected with the gland 1, the resilience force exerted by the spring 22 on the pressing block 3 enables the pressing block 3 to exert pressure on the optical fiber, so that the pressing pads 4 on the two pressing blocks 3 can firmly press the two ends of the optical fiber. Both ends of each pressing block 3 are provided with a connecting piece 21 and a spring 22, so that the stability of the optical fiber is further enhanced.
The embodiment of the application provides a top cover of optic fibre cutting knife, set the type of floating through briquetting 3 with the top cover, with lower briquetting cooperation and when pressing from both sides optic fibre tightly, even there are the dust between the briquetting, the circumstances such as wearing and tearing, the elasticity that spring 22 provided still can make briquetting 3 and optic fibre in close contact with and press from both sides tightly, the briquetting 3 of having solved the fixed type can't be firm optic fibre of pushing down under the circumstances that has dust and wearing and tearing, lead to the untidy problem of optic fibre cutting.
On the basis of the above embodiment, the upper cover of the optical fiber cutting knife can be further optimized.
The floating assembly 2 further comprises a pressing plate 23, the pressing plate 23 is provided with 4 positioning holes with the diameter smaller than the cross section of the head of the connecting piece 21, and the rod part of the connecting piece 21 sequentially penetrates through the positioning holes, the spring 22 and the mounting hole 32 of the pressing block 3 to be fixedly connected with the pressing cover 1. A pressure plate 23 is provided to facilitate the positioning of the 4 connector 21 positions.
Furthermore, the pressing plate 23 may further have a fixing hole 24 for fixing the pressing plate 23 on the gland 1. Specifically, the pressing plate 23 is fixed to the gland 1 by means of screws passing through the fixing holes 24 to be connected to the gland 1.
Further, threaded grooves are formed at both ends of the through hole through which the mounting portion 31 of the pressure pad 3 passes, and the positions of the threaded grooves correspond to the positions of the mounting holes 32 (located inside the range shown in fig. 2, not shown). The connecting piece 21 is specifically a bolt, and a screw rod of the bolt sequentially penetrates through the spring 22 and the mounting hole 32 of the pressing block 3 to be in threaded connection with the thread groove, so that the fixed connection with the gland 1 is realized.
Further, the top of the gland 1 is provided with a bulge 11, and the pressing block 3 is embedded in the bulge. There is a certain area between the two protrusions 11 to facilitate the penetration of the blade of the fiber cleaver.
The second aspect of the present application provides an optical fiber cleaver, comprising a cleaver body and an upper cover as provided in the first aspect. The upper cover is movably connected with the cutter main body, and a lower pressing block on the cutter main body is matched with the floating pressing block 3 in the upper cover to clamp the optical fiber.
