Abstract
Description
[0001] The present application claims priority over the Chinese patent application filed on 4 September 2023 and with application number 202311142432.1, all contents of which are incorporated into the present application by reference. TECHNICAL AREA
[0002] The present application relates to the technical field of industrial compressors, in particular a buffer piston structure and a device for mounting a fragile component. STATE OF THE ART
[0003] Currently, an optical fiber consists of a core, a cladding and a coating, with the core and cladding material being mainly silicon dioxide.
[0004] A fiber optic structure component refers to a component that acquires specific functional properties through the processing of an optical fiber. Examples include optical gratings, mode field adapters, cladding wipers, fiber combiners, and fiber couplers.
[0005] The main body of a fiber optic structure component is manufactured by processing an optical fiber and is prone to breakage or microscopic deformation under stress, leading to changes in some of the component's properties. For example, the light spot of a laser beam propagating in the optical fiber can change under stress.
[0006] Common sources of force acting on a fiber optic structure include: 1. Vibrations and shocks, which subject the fiber optic structure to a certain acceleration and thus a force; 2. Attachment of the two fiber ends to a base material. When the ambient temperature changes, the different coefficients of thermal expansion of the optical fiber and the base material cause the optical fiber to be subjected to tensile or compressive forces.
[0007] For example, in the Fig. In the structure shown in Figure 1, the fiber optic structure component is bonded to the base material using adhesive. If a hard adhesive is used, the optical fiber is rigidly connected to the base material. During vibrations and shocks, the force acting on the fiber optic structure component is directed along the axial direction of the optical fiber. Since the magnitude of the force is related to acceleration and mass, and the mass is typically small, the axial force acting on the fiber is also small, so breakage does not usually occur. However, changes in ambient temperature subject the fiber optic structure component to greater tensile or compressive forces, leading to changes in the internal laser beam spot. When a soft adhesive is used, the optical fiber is flexibly connected to the base material.Vibrations and shocks can lead to misalignment of the optical fiber, causing the force direction to deviate from the axial direction of the optical fiber and resulting in fiber breakage. Changes in ambient temperature do not cause significant tensile or compressive forces due to shrinkage of the optical fiber against the soft adhesive. In summary, the fiber optic structure component is at risk of either spot changes or breakage, regardless of whether a hard or soft adhesive is used. CONTENT OF THE PRESENT INVENTION: Technical Problem
[0008] The present application aims to overcome the disadvantages of the prior art and provide a buffer piston structure and a device for mounting a fragile component, whereby a piston can move slowly under slowly acting forces on the component, while still maintaining a relatively slow movement under suddenly acting forces. This serves to solve fastening problems for components and products that must not be subjected to rigid forces and exhibit slow response times. Technical solution
[0009] According to the present application, the problem is solved by a buffer piston structure comprising the following: two cylindrical sections that serve to hold a filling material; and two piston sections, each appropriately sealed and movably mounted in receiving cavities of the two cylinder sections, wherein the two piston sections are coupled to each other in terms of movement; wherein a resistance flow channel is formed on the buffer piston structure, which connects the receiving cavities of the two cylinder sections and serves to ensure that when the piston sections are moved in the respective cylinder sections, the filling material from one of the cylinder sections is slowly conveyed via the resistance flow channel into the other cylinder section.
[0010] In one embodiment, it is provided that the two piston sections are formed in one piece; and / or that the two cylinder sections are formed in one piece.
[0011] In one embodiment, the buffer piston structure comprises a cylinder in which a piston is provided; wherein the two piston sections comprise two opposite end regions of the piston; wherein the two cylinder sections comprise two opposite end regions of the cylinder.
[0012] In one embodiment, the resistance flow channel is formed on the piston.
[0013] In one embodiment, the resistance flow channel is formed between the piston and the inner wall of the cylinder.
[0014] In one embodiment, the resistance flow channel is provided for between two opposing end regions of the cylinder.
[0015] In one embodiment, the piston is a rigid piston.
[0016] In one embodiment, the buffer piston structure further comprises a filling material containing anhydrous propanol, and accordingly, the resistance flow channel comprises a capillary tube.
[0017] The present application further proposes a device for assembling a fragile component, comprising the buffer piston structure. The device for assembling a fragile component comprises: two cylindrical sections that serve to hold a filling material; and two piston sections, each appropriately sealed and movably mounted in receiving cavities of the two cylinder sections, wherein the two piston sections are coupled to each other in terms of movement; wherein a resistance flow channel is formed on the buffer piston structure, which connects the receiving cavities of the two cylinder sections and serves to ensure that when the piston sections are moved in the respective cylinder sections, the filling material from one of the cylinder sections is slowly conveyed via the resistance flow channel into the other cylinder section.
[0018] In one embodiment, the fragile component body comprises a fiber optic structure component. Beneficial effects:
[0019] In the technical solution provided by the present application, the assembly steps are simple for the operator and it is ensured that the piston sections of the buffer piston structure can move slowly between the two cylinder sections in the event of short-term impact forces of high intensity on the fragile component.During extremely short periods, the piston sections remain practically motionless, whereas during thermal expansion or contraction of the fragile component due to environmental influences, the compressive and tensile forces acting on the fragile component are low but act over a longer period, allowing the piston sections of the buffer piston structure to move synchronously. This prevents the fragile component from being subjected to excessive forces: it experiences neither short-term tensile or compressive forces of high intensity nor long-term tensile or compressive forces of high intensity, thus protecting the fragile component from damage or undesirable changes in its properties due to force application.

[0025] Currently, an optical fiber consists of a core, a cladding and a coating, with the core and cladding material being mainly silicon dioxide.
[0026] A fiber optic structure component refers to a component that acquires specific functional properties through the processing of an optical fiber. Examples include optical gratings, mode field adapters, cladding wipers, fiber combiners, and fiber couplers.
[0027] The main body of a fiber optic structure component is manufactured by processing an optical fiber and is prone to breakage or microscopic deformation under stress, leading to changes in some of the component's properties.

[0028] Common sources of force acting on a fiber optic structure include: 1. Vibrations and shocks, which subject the fiber optic structure to a certain acceleration and thus a force; 2. Attachment of the two fiber ends to a base material. When the ambient temperature changes, the different coefficients of thermal expansion of the optical fiber and the base material cause the optical fiber to be subjected to tensile or compressive forces.
[0029] For example, in the Fig. In the structure shown in Figure 1, the fiber optic structure component is bonded to the base material using adhesive. If a hard adhesive is used, the optical fiber is rigidly connected to the base material. During vibrations and shocks, the force acting on the fiber optic structure component is directed along the axial direction of the optical fiber.

When a soft adhesive is used, the optical fiber is flexibly connected to the base material.Vibrations and shocks can lead to misalignment of the optical fiber, causing the force direction to deviate from the axial direction of the optical fiber and resulting in fiber breakage. Changes in ambient temperature do not cause significant tensile or compressive forces due to shrinkage of the optical fiber against the soft adhesive. In summary, the fiber optic structure component is at risk of either spot changes or breakage, regardless of whether a hard or soft adhesive is used.
[0030] Against this background, the present application provides a buffer piston structure 10. Fig. 3, Fig. 4, Fig. 5 to Fig. Figure 6 shows four embodiments according to the present application.
[0031] It will be on Fig. Figure 3, which is a schematic representation of an embodiment of the present application, is shown. A buffer piston structure 10 is provided. The buffer piston structure 10 comprises two cylinder sections 1 and two piston sections 2. The two cylinder sections 1 serve to hold a filling material 11. The two piston sections 2 are each appropriately sealed and movably mounted in receiving cavities of the two cylinder sections 1, with the two piston sections 2 being coupled to each other in their movement. A resistance flow channel 3 is formed on the buffer piston structure 10, which connects the receiving cavities of the two cylinder sections 1 and serves to ensure that, when the piston sections 2 move within their respective cylinder sections 1, the filling material 11 is slowly conveyed from one of the cylinder sections 1 to the other cylinder section 1 via the resistance flow channel 3.Thus, piston 2a can move slowly under slowly acting forces on the component, while piston 2a can still maintain a relatively slow movement under suddenly acting forces. This serves to solve fastening problems for components and products that must not be subjected to rigid forces and have slow response times.
[0032] In the technical solution provided by the present application, the assembly steps are simple for the operator and it is ensured that the piston sections 2 of the buffer piston structure 10 can move slowly between the two cylinder sections 1 in the event of short-term impact forces of high intensity on the fragile component.During extremely short periods, the piston sections 2 do not move at all, whereas during thermal expansion or contraction of the fragile component due to environmental influences, the compressive and tensile forces acting on the fragile component are small, but act over a longer period, allowing the piston sections 2 of the buffer piston structure 10 to move synchronously, so that the fragile component is not subjected to excessive forces: It experiences neither short-term tensile or compressive forces of greater intensity nor long-term tensile or compressive forces of greater intensity, thus protecting the fragile component from damage or undesirable changes in its properties due to force application.
[0033] In the present embodiment, the two piston sections 2 are formed in one piece and the two cylinder sections 1 are also formed in one piece, as in Fig. 3, Fig. 4 to Fig. 5 shown.
[0034] The buffer piston structure 10 comprises a cylinder 1a in which a piston 2a is provided. The two piston sections 2 comprise two opposing end regions of the piston 2a, and the two cylinder sections 1 comprise two opposing end regions of the cylinder 1a.
[0035] As in Fig. As shown in Figure 3, the resistance flow channel 3 can be arranged on the piston 2a. Alternatively, as shown in Fig. As shown in Figure 4, the resistance flow channel 3 can also be formed between the piston 2a and the inner wall of the cylinder 1a. In another possibility, shown in Figure 4, the resistance flow channel 3 can also be formed between the piston 2a and the inner wall of the cylinder 1a. Fig. 5, the resistance flow channel 3 can be provided between two opposite end regions of the cylinder 1a, the resistance flow channel 3 being briefly described functionally here.
[0036] In another embodiment, as in Fig. As shown in Figure 6, the cylinders 1a can be arranged at a distance from each other. The piston 2a is movably connected to both cylinders 1a. One end of the resistance flow channel 3 can be located on the left side of one of the cylinders 1a, while the other end of the resistance flow channel 3 is located on the right side of the other cylinder 1a. Alternatively, one end of the resistance flow channel 3 can be located on the right side of one of the cylinders 1a and the other end of the resistance flow channel 3 on the left side of the other cylinder 1a.
[0037] The piston 2a is preferably designed as a rigid piston 2a. From a mechanical point of view, the use of a lightweight, rigid piston 2a is particularly recommended for the piston 2a, as it offers the advantages of low deformation tendency and low weight.
[0038] In one embodiment, the filling material 11 comprises anhydrous propanol 11a. Accordingly, the resistance flow channel 3 can be configured as a group of capillary tubes 3a. When a force acts on the piston 2a, the anhydrous propanol 11a flows through the capillary tubes 3a to the other side. The anhydrous propanol 11a is a colorless, transparent liquid with a slightly ethanol-like odor. It can be produced by subjecting a starting gas with a propene content of over 50% at 50°C and low pressure to an absorption reaction with 75% to 85% concentrated sulfuric acid, forming isopropyl hydrogen sulfate. The isopropyl hydrogen sulfate is then hydrolyzed to isopropanol.A concentration of 95% is achieved through coarse distillation in a distillation tower, followed by extraction with benzene, water removal, and then redistillation, yielding a final product with an isopropanol content exceeding 99%. Alternatively, propene and water are each pressurized to 1.96 MPa. They are then preheated to 200°C and, after mixing, introduced into a reactor where a hydration reaction takes place. After neutralization and heat exchange, the reaction gases are directed to a high-pressure condenser and a high-pressure separator. The isopropanol in the gas phase is recovered in a recovery tower by spraying it with deionized water.Distillation in a coarse distillation tower yields an 85% to 87% aqueous isopropanol solution, which is concentrated to 95% in a distillation tower and then extracted with benzene to obtain isopropanol with over 99% purity. Here, the term "capillary tube 3a" typically refers to a thin tube with an inner diameter of 1 millimeter or less.
[0039] In another embodiment, the filling material 11 can also be anhydrous propanol 11a, and the resistance flow channel 3 is designed as a group of fine grooves between the piston 2a and the cylinder wall. When force is applied to the piston 2a, the anhydrous propanol 11a flows through the fine grooves to the other side.
[0040] Here, the filling material 11 interacts with the resistance flow channel 3. The resistance flow channel 3 can be designed based on the selection of the filling material 11. Likewise, the corresponding filling material 11 can be determined by the resistance flow channel 3. The selection of the filling material 11 is not limited and can be a gaseous, liquid, or glassy fluid. The resistance flow channel 3 can be selected according to the filling material 11, as described above, for example, as a group of capillary tubes 3a or as a group of fine grooves between the piston 2a and the cylinder wall.Obviously, the selection is not limited to this, as long as the interaction of the filling material 11 and the resistance flow channel 3 ensures that, when force is applied to the piston 2a, the filling material 11 is slowly conveyed from one of the cylinder sections 1 through the resistance flow channel 3 into the other cylinder section 1, while the piston sections 2 move within the cylinder sections 1.
[0041] The present application further proposes a device 100 for mounting a fragile component. Referring to Fig.The device 100 for assembling a fragile component comprises a fragile component body 20, a base material 30, a support section 40, and the buffer piston structure 10. The base material 30 is arranged on the piston 2a and serves to firmly connect it to one end of the fragile component body 20. The support section 40 is firmly connected to the other end of the fragile component body 20 and serves to support the fragile component body 20 and to align it parallel to a plane on which a reference object 50 is located. The reference object can be any surface, such as the floor, a table surface, or a mounting platform, as long as the buffer piston structure 10 can be placed on it.The support section 40 can also be a support column or a support axis, as long as it is capable of supporting the fragile component body 20 in such a way that the fragile component body 20 remains aligned parallel to the plane on which the reference object 50 is located. Due to the use of all the technical solutions of all the above embodiments, the device 100 for mounting a fragile component also exhibits all the advantageous effects achieved by the technical solutions of the above embodiments, and a detailed description is therefore omitted here.
[0042] In one embodiment, the fragile component body 20 can be configured as a fiber optic structure component 20a. The term "fiber optics" is short for optical fiber and refers to a fiber made of glass or plastic. An optical fiber consists of two layers of glass with different refractive indices. The inner layer forms the optical waveguide core with a diameter of a few micrometers to several dozen micrometers, while the outer layer has a diameter of 0.1 to 0.2 mm. Typically, the refractive index of the core glass is about 1% higher than that of the outer layer glass. According to the principles of refraction and total internal reflection, light is completely reflected at the interface between the core and the outer layer when the angle of incidence exceeds a critical angle for total internal reflection, so that no light passes through the interface.In another embodiment, the fragile component body 1 can also be designed as a glass tube. In principle, all fragile and damage-prone components are suitable for the device according to the present application.
[0043] Establishing a connection between the piston 2a and the fragile component body 20 is not straightforward. Therefore, in the present embodiment, a base material 30 is provided that connects one end of the fragile component body 20 to the piston 2a, thus simplifying assembly. To ensure that the fragile component body 20 is aligned parallel to the plane on which the reference object 50 is located, and can therefore be mounted more stably and securely, a support column is provided between the other end of the fragile component body 20 and the reference object 50.
[0044] The assembly of the device 100 for mounting a fragile component comprises the following steps: First, the two cylinders 1a are filled with the filling material 11. The two piston sections 2 are each tightly and movably mounted in the receiving cavities of the two cylinder sections 1, so that the two piston sections 2 are coupled to each other in their movement. Subsequently, the resistance flow channel 3 is formed on the buffer piston structure 10, which connects the receiving cavities of the two cylinder sections 1. This allows the filling material 11 to be slowly conveyed from one of the two cylinders 1a to the other cylinder 1a when force is applied to an individual piston section 2. The base of the buffer piston structure 10 is attached to the reference object 50. The base material 30 is fixed to the piston 2a.Depending on the height of the base material 30 relative to the reference object 50, the support section 40 is attached to the reference object 50 such that the line connecting the support section 40 and the base material 30 is parallel to the plane on which the reference object 50 is located. Finally, one end of the fragile component body 20 is attached to the upper part of the base material 30 and the other end to the support section 40. The base material 30 can consist of, among other things, plywood sheets, plasterboard, wooden battens, filler, a cement-sand mixture, or lightweight steel profiles.
[0045] So far, only optional embodiments of the present application have been explained, which in no way limits the scope of the patent. Any equivalent structural modifications based on the description and the accompanying drawings of the present application, within the scope of the basic ideas of the present application, or direct / indirect applications in the relevant technical fields, are covered by the scope of protection of the present application.
