Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber production, in particular to a pressure tool for preventing compression injuries. Background Art

[0002] Optical fiber, also known as optical fiber, is a fiber made of glass or plastic, mainly used for light conduction. It uses the principle of total internal reflection of light in the fiber for transmission. It is an efficient and high-speed information transmission medium. Its main applications include the Internet, medical, military, aerospace and other fields.

[0003] The optical fiber may bend or twist in the processing process. If it is not pressed, the optical fiber may maintain these irregular shapes, causing problems in the subsequent installation and use. Pressing helps to ensure the stability of the optical fiber during storage and transportation, prevent damage to the optical fiber, improve the arrangement of the optical fiber, and enhance the mechanical properties of the optical fiber. At present, most of the existing pressing devices have sharp edges of the pressing plate during the pressing process, which can easily scratch the optical fiber. In view of this, we propose an anti-crushing press. Utility Model Content

[0004] The main purpose of the utility model is to provide a pressure tool for preventing crush injuries, which can solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes an anti-compression press, including a rod body, a clamp 1 is provided under the rod body, a clamp 2 is provided on the outside of the clamp 1, and a pressure plate is provided inside the clamp 2 for pressing the optical fiber. Through pressing, the optical fiber can be kept flat and straight, which is easier to install and connect.

[0006] Preferably, a threaded block is fixedly connected to the outer wall of the bottom end of the rod body, and the threaded block cooperates with the threaded groove one to connect the rod body and the clamp one.

[0007] Preferably, the outer wall of the clamp 1 is provided with a thread groove 1, which cooperates with the thread block. The thread block and the thread groove 1 cooperate to connect the clamp 1 and the rod body, and a thread groove 2 is provided on one side wall of the clamp.

[0008] Preferably, the second clamp is provided with a groove, and connecting grooves are respectively provided on both sides of the groove, and the connecting groove and the second thread groove cooperate with each other, and the second clamp can be connected to the first clamp by fixing with bolts.

[0009] Preferably, the pressing plate is fixedly connected to the inner wall of the groove, the material of the pressing plate is glass, and the right-angled edge of the pressing plate is provided with a chamfer to prevent the sharp angle at the bottom of the pressing plate from cutting the optical fiber during the process of pressing the optical fiber.

[0010] Preferably, the clamps 2 are provided with two groups in total, and the two groups of the clamps 2 are movably mounted on the side walls of the clamp 1 respectively.

[0011] The utility model provides a pressure tool for preventing crush injuries. It has the following beneficial effects:

[0012] (1) The anti-crushing press has a chamfered bottom edge of the pressing plate to eliminate the existence of sharp angles. When pressing the optical fiber, the optical fiber will not be cut or scratched due to contact with the sharp angle. At the same time, the chamfer makes the contact surface smoother, and the optical fiber can pass more smoothly during the pressing process, reducing friction and resistance, thereby improving the pressing efficiency.

[0013] (2) The components of the anti-crushing press are connected by threads, which makes the assembly process simple and quick. At the same time, the disassembly is also relatively convenient. When maintenance or replacement of parts is required, the threaded connection can be easily removed, thereby improving the maintainability and repairability of the press.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 5 The utility model proposes an anti-pressure injury pressing tool, including a rod body 1, a threaded block 11 is fixedly connected to the outer wall of the bottom end of the rod body 1, a clamp 2 is arranged below the rod body 1, a threaded groove 21 is opened on the outer wall of the clamp 2, a threaded groove 22 is opened on the side wall of the clamp 2, a clamp 2 3 is arranged on the outer side of the clamp 2, a groove 32 is opened on the clamp 2 3, and connecting grooves 31 are respectively opened on both sides of the groove 32. A pressing plate 4 is arranged inside the clamp 2 3, such as Figure 5 As shown, the bottom edge of the pressing plate 4 is provided with a chamfer to prevent the risk of the optical fiber being cut while pressing the optical fiber. Such a design not only improves the safety of optical fiber processing, but also reduces the production cost and improves the production efficiency. The pressing plate 4 is fixedly connected to the inner wall of the groove 32, and the clamp 2 3 is provided with two groups. The two groups of clamps 2 3 are movably installed with the side walls of the clamp 1 2 respectively. The various components of the tooth tool are connected by threads, which makes the assembly process simple and quick. At the same time, the disassembly is also relatively convenient. When maintenance or replacement of parts is required, the threaded connection can be easily disassembled, which improves the maintainability and repairability of the press.

[0025] This design is a press for pressing optical fiber. The optical fiber may bend or twist to a certain extent during the processing. If it is not pressed, the optical fiber may maintain these irregular shapes, resulting in problems in the subsequent installation and use. By pressing, the optical fiber can be kept flat and straight, which is more convenient for installation and connection. Secondly, pressing the optical fiber can enhance the mechanical strength of the optical fiber. Although the optical fiber itself has a high transmission performance, its mechanical strength is relatively low and it is easily affected by external forces. By pressing, the pressure resistance and bending resistance of the optical fiber can be increased to a certain extent, and the durability and reliability of the optical fiber can be improved. In addition, pressing the optical fiber can also improve the density and compactness of the optical fiber. When placing the optical fiber in the container, the optical fiber can be arranged more closely by pressing, and the gaps between the optical fibers can be reduced, thereby improving the space utilization rate of the optical fiber in the container. By designing the chamfer of the pressing plate 4, the risk of the optical fiber being cut by a sharp angle in the device can be avoided while pressing the optical fiber. By pressing, the optical fiber can be more closely attached to the bottom of the device, reducing the contact between the optical fiber and the sharp angle part of the device, thereby protecting the optical fiber from being cut.

[0026] In the utility model, when in use, firstly, the clamp 2 3 is connected with the clamp 1 2 by bolts, then the pressure plate 4 is fixed in the groove 32, and then the clamp 1 2 is threadedly connected with the rod body 1. When the optical fiber is processed, the optical fiber is placed in the container, and then the device is started to drive the press to press the optical fiber.

[0027] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
