Description

Buffer piston structure and fragile parts installation device

[0001] This application claims priority to Chinese patent application No. 202311142432.1 filed on September 4, 2023, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of industrial compressors, and in particular to a buffer piston structure and a mounting device for fragile and wearing parts. Background Art

[0003] Currently, optical fiber is composed of a core, a cladding and a coating, and the materials of the core and the cladding are mainly silica.

[0004] Fiber optic components refer to devices that have been processed on optical fibers to give them certain properties and functions. Examples include gratings, mode field adapters, cladding strippers, fiber combiners, and fiber couplers.

[0005] Fiber optic components are made from optical fibers, which can break easily when subjected to stress. When stressed, they can also undergo micro-deformation, changing some of their characteristics. For example, when stressed, the spot of a laser beam propagating through the fiber can change.

[0006] Common sources of force on optical fiber structural devices: First, during vibration and impact, the optical fiber structure is subjected to a certain acceleration, thereby being subjected to force; second, the two ends of the optical fiber are fixed on a certain substrate. When the ambient temperature changes, the thermal expansion and contraction coefficients of the optical fiber and the substrate are inconsistent, causing the optical fiber to be subjected to tension or extrusion.

[0007] For example, in the structure of Figure 1, the optical fiber structural device is bonded to the substrate with glue: if the glue is hard glue, the optical fiber is rigidly connected to the substrate. When vibration impact occurs, the force on the optical fiber structural device is consistent with the axial direction of the optical fiber. In addition, the magnitude of the force is related to acceleration and mass. Under normal circumstances, the smaller the mass, the smaller the axial force on the optical fiber, and generally it will not break. When the ambient temperature changes, the optical fiber structural device is subjected to greater tension or extrusion, causing the internal laser beam spot to change. If the glue is soft glue, the optical fiber is softly connected to the substrate. When vibration impact occurs, it may cause the optical fiber to be fixed and misaligned, resulting in the force direction of the optical fiber being misaligned with the axial direction of the optical fiber, causing the optical fiber to break. When the ambient temperature changes, the contraction of the optical fiber on the soft glue will not cause greater tension or extrusion. In summary, whether hard glue or soft glue is used, the optical fiber structural device may either change the spot or break. Technical issues

[0008] The main purpose of this application is to overcome the defects of the existing technology and to propose a buffer piston structure and a fragile part installation device, which aims to solve the problem of the piston moving slowly when the component is slowly stressed, and maintaining relatively slow movement when the component is rapidly stressed. It is applied to the fixing problem of component products that cannot be subjected to rigid stress and have slow response time. Technical Solutions

[0028] In the technical solution provided in the present application, the operator has simple installation steps, and ensures that when the fragile wearing parts are subjected to a strong and short-duration impact force, the piston part of the buffer piston structure can move slowly between the two cylinder parts. When the time is very short, the piston part hardly moves.

At this time, the piston part of the buffer piston structure can move synchronously, so that the fragile wearing parts will not be subjected to excessive force, so that the fragile wearing parts will not be subjected to large short-term tension or pressure, nor will they be subjected to large long-term tension or pressure, thereby protecting the fragile wearing parts from damage or changes in certain characteristics due to force.

[0047] In view of this, the present application provides a buffer piston structure 10 , and FIG. 3 to FIG. 6 are four embodiments provided in the present application.

[0048] Please refer to Figure 3, which is a schematic diagram of an embodiment of the present application, which proposes a buffer piston structure 10, the buffer piston structure 10 includes two cylinder parts 1 and two piston parts 2, the two cylinder parts 1 are used to set the filling body 11, the two piston parts 2 are respectively and correspondingly installed in the cavities of the two cylinder parts 1, the two piston parts 2 are linked, and a resistance flow channel 3 is formed on the buffer piston structure 10, the resistance flow channel 3 connects the cavities of the two cylinder parts 1, and is used for when the piston part 2 moves inside the cylinder part 1, the filling body 11 in one of the cylinder parts 1 is slowly transferred to the other cylinder part 1 through the resistance flow channel 3. It is intended to solve the problem that the piston 2a can move slowly when the component is slowly stressed, and the piston 2a can also maintain relatively slow movement when it is rapidly stressed. It is applied to the fixation problem of component products that cannot be rigidly stressed and have slow response time.

[0049] In the technical solution provided in the present application, the operator has simple installation steps, and ensures that when the fragile wearing parts are subjected to a strong and short-term impact force, the piston part 2 of the buffer piston structure 10 can move slowly between the two cylinder parts 1. When the time is very short, the piston part 2 hardly moves. When the fragile wearing parts are affected by the external environment and expand and contract due to heat and cold, the thrust and pull forces on the fragile wearing parts are very small and the force is applied for a long time. At this time, the piston part 2 of the buffer piston structure 10 can move synchronously, so that the fragile wearing parts will not be subjected to excessive force, so that the fragile wearing parts will not be subjected to large short-term tension or pressure, nor will they be subjected to large long-term tension or pressure, thereby protecting the fragile wearing parts from damage or changes in certain characteristics due to force.

[0050] In this embodiment, the two piston parts 2 are integrally provided, and the two cylinder parts 1 are integrally provided, as shown in FIG. 3 to FIG. 5 .

[0051] The buffer piston structure 10 includes a cylinder 1 a in which a piston 2 a is disposed. The two piston parts 2 include opposite ends of the piston 2 a and the two cylinder parts 1 include opposite ends of the cylinder 1 a.

[0052] Please refer to Figure 3, the resistance flow channel 3 can be set on the piston 2a, refer to Figure 4, the resistance flow channel 3 can also be set between the piston 2a and the inner wall of the cylinder body 1a, refer to Figure 5, the resistance flow channel 3 can also be set between the two opposite ends of the cylinder body 1a, wherein the resistance flow channel 3 is a functional overview.

[0053] Please refer to Figure 6. In another embodiment, the cylinder bodies 1a may be spaced apart by a certain distance, the pistons 2a are movably connected to the two cylinder bodies 1a respectively, one end of the resistance flow channel 3 may be set on the left side of one of the cylinder bodies 1a, and the other end of the resistance flow channel 3 may be set on the right side of the other cylinder body 1a; or one end of the resistance flow channel 3 may be set on the right side of one of the cylinder bodies 1a, and the other end of the resistance flow channel 3 may be set on the left side of the other cylinder body 1a.

[0054] The piston 2a is preferably a rigid piston 2a. From a mechanical point of view, the piston 2a is preferably a lightweight rigid piston 2a, which has the advantages of being less prone to deformation and having a small mass.

[0055] In one embodiment, the filler 11 contains anhydrous propanol 11a. The corresponding resistance flow channel 3 can be configured as a set of capillaries 3a. When the piston 2a is subjected to force, the anhydrous propanol 11a flows through the capillaries 3a to the other side. The anhydrous propanol 11a is a colorless, transparent liquid with a slight ethanol odor. It can be prepared by subjecting feed gas containing at least 50% propylene to an absorption reaction with 75% to 85% concentrated sulfuric acid at 50°C and low pressure to produce isopropyl hydrogen sulfate. The isopropyl hydrogen sulfate is then hydrolyzed to isopropyl alcohol. After crude distillation, the product is concentrated to 95% using a distillation tower, extracted with benzene, and the water is separated before distillation to produce a finished product containing at least 99% isopropyl alcohol. Alternatively, propylene and water can be pressurized to 1.96 MPa, preheated to 200°C, mixed, and added to a reactor for a hydration reaction. After neutralization and heat exchange, the reaction gas is sent to a high-pressure cooler and high-pressure separator. The isopropyl alcohol in the gas phase is recovered in a recovery tower by spraying with deionized water. It is then distilled in a crude distillation tower to produce an 85% to 87% isopropyl alcohol aqueous solution. This is then concentrated to 95% in a distillation tower and extracted with benzene to produce over 99% isopropyl alcohol. The capillary tube 3a typically refers to a thin tube with an inner diameter of 1 mm or less.

[0056] In another embodiment, the filler 11 may be anhydrous propanol 11a, and the resistance flow channel 3 is a set of fine grooves reserved between the piston 2a and the cylinder wall. When the piston 2a is subjected to force, the anhydrous propanol 11a flows to the other side through the fine grooves.

[0057] Among them, the filling body 11 and the resistance flow channel 3 have a synergistic effect. The resistance flow channel 3 can be set through the filling body 11, or the corresponding filling body 11 can be set through the resistance flow channel 3. The selection of the filling body 11 is not restricted, and it can be set to a fluid material such as gas, liquid or glass. The resistance flow channel 3 can be selected through the filling body 11. As mentioned above, it can be set to a group of capillaries 3a or a group of fine grooves can be retained between the piston 2a and the cylinder wall. Obviously, the choice is not limited to this, as long as the synergistic effect of the filling body 11 and the resistance flow channel 3 can meet the requirement that when the piston 2a is subjected to force, the piston part 2 moves inside the cylinder part 1, and the filling body 11 in one of the cylinder parts 1 is slowly transmitted to the other cylinder part 1 through the resistance flow channel 3.

[0058] The present application also provides a fragile wear part installation device 100. Referring to FIG2 , the fragile wear part installation device 100 includes a fragile wear part body 20, a substrate 30, a support portion 40, and the buffer piston structure 10. The substrate 30 is provided on the piston 2a and is fixedly connected to one end of the fragile wear part body 20. The support portion 40 is fixedly connected to the other end of the fragile wear part body 20 to support the fragile wear part body 20 and make it parallel to the plane of the reference object 50. The reference object can be any placement surface, such as the ground, a tabletop, or a mounting platform, as long as the buffer piston structure 10 can be placed thereon. The support portion 40 can also be a support column or a support shaft, as long as it can support the fragile wear part body 20 so that it is parallel to the plane of the reference object 50. Since this fragile wearing part installation device 100 adopts all the technical solutions of the above embodiments, it also has the technical effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0059] In one embodiment, the fragile and damaging part body 20 may be an optical fiber device 20a. The optical fiber is short for optical fiber, which is a fiber made of glass or plastic. The optical fiber is composed of two layers of glass with different refractive indices. The inner layer is the optical core, with a diameter ranging from a few microns to tens of microns, and the outer layer has a diameter of 0.1 to 0.2 mm. Generally, the refractive index of the inner core glass is 1% greater than that of the outer layer glass. According to the principles of refraction and total reflection of light, when the angle at which light hits the interface between the inner core and the outer layer is greater than the critical angle for total reflection, the light cannot pass through the interface and is completely reflected. In another embodiment, the fragile and damaging part body 1 may also be a glass tube. Any fragile and easily damaged component can be used in the device of this application.

[0060] Among them, it is not easy to connect the piston 2a and the fragile wearing part body 20. In this embodiment, a substrate 30 is provided, and the substrate 30 connects one end of the fragile wearing part body 20 and the piston 2a, which has the advantage of more convenient installation. In order to make the fragile wearing part body 20 parallel to the plane where the reference object 50 is located, so that the fragile wearing part body 20 is more stable and the installation is more secure, a support column is provided between the other end of the fragile wearing part body 20 and the reference object 50.

Slowly transport it into the other cylinder 1a; fix the bottom of the buffer piston structure 10 to the reference object 50; fix the base material 30 to the piston 2a; fix the support part 40 to the reference object 50 corresponding to the height of the base material 30 to the reference object 50, so that the line connecting the support part 40 and the base material 30 is parallel to the plane of the reference object 50; finally, fix one end of the fragile wear part body 20 to the upper part of the base material 30 and the other end to the support part 40. The base material 30 includes wood board, gypsum board, wooden keel, putty powder, cement sand, light steel keel, etc.
