Abstract
Description
Technical Field
[0001] This utility model relates to the field of flexible connection structures for pneumatic components, and more specifically, to a flexible connection structure for pneumatic components. Background Technology
[0002] Pneumatic components are devices that perform work by utilizing the force generated by the pressure or expansion of gas. They are mechanisms that convert the elastic energy of compressed air into kinetic energy. Existing pneumatic components need to ensure good stability during use. Various pipe fittings are required to connect pneumatic components. When vibration occurs during use, the pipe fittings will bend due to two different vibration sources. Moreover, they are easily deformed when squeezed, affecting the ventilation effect. Furthermore, some connecting pipe fittings are integrally molded, so the operating angle cannot be adjusted, resulting in limited operating conditions.
[0003] In its use, existing technologies, such as the one disclosed in patent announcement number CN218000846U, provide a flexible connection structure for pneumatic components, including an auxiliary tube frame. Fixing mechanisms are connected to both ends of the inner wall of the auxiliary tube frame. Connecting pipes are connected inside the auxiliary tube frame, with both ends of the connecting pipes connected to the fixing mechanisms. A guiding mechanism is connected to one side of the auxiliary tube frame. The auxiliary tube frame includes a first pipe and a second pipe. The ends of the first and second pipes that are close to each other are hinged, and their ends that are far apart are both connected to connecting ends. The fixing mechanisms are connected to both ends of the inner walls of the first and second pipes. This invention effectively avoids deformation due to compression and vibration, ensuring performance. It has a simple structure and is easy to use.
[0004] In the aforementioned patent, a two-section pipe structure with a 90-degree hinge is used. Its external support components are fixed inflexibly, and the internal pipe is supported by rigid support with poor elasticity. When vibrating, it cannot flexibly adjust the angle on its own, resulting in low buffering performance. Utility Model Content
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a flexible connection structure for pneumatic components. When used at non-specific angles, the connecting pipe is directly supported by an external spring. During vibration and shaking, the spring provides elastic support, and during bending, it provides elastic support to prevent damage. When a specific angle is required, an elastic strip structure is installed to allow the connecting pipe to bend and then be positioned. The specific angle can be adjusted for use, making it flexible and convenient to use.
[0006] To solve the above problems, the present invention adopts the following technical solution.
[0007] A flexible connection structure for a pneumatic component includes a connecting pipe. The outer end of the connecting pipe has a threaded protrusion, which is distributed across the upper and lower end faces of the connecting pipe. A first compression mounting plate is fixed to the outer surface of the upper threaded protrusion of the connecting pipe by a first nut. A second compression mounting plate is fixed to the outer surface of the lower threaded protrusion of the connecting pipe by a second nut. A spring is compression-fixed between the first and second compression mounting plates, and the spring is sleeved on the outer end of the connecting pipe. An elastic strip is installed between the first and second compression mounting plates. When used at a non-specific angle, the connecting pipe is directly supported by the external spring. During vibration or shaking, the spring provides elastic support, and during bending, it provides elastic support to prevent damage. When a specific angle is required, the elastic strip structure allows the connecting pipe to bend and then reposition itself. The specific angle is adjustable, making it flexible and convenient to use.
[0008] Furthermore, the elastic strip adopts a curved strip structure and is made of elastic steel.
[0009] Furthermore, the inner surfaces of the outer ends of the first and second extrusion mounting discs are connected by bolts via threads, and the bolts are extruded and fixed to the surface of the elastic strip.
[0010] Furthermore, the outer surfaces of the first and second extrusion mounting discs are provided with insertion openings, and the outer surface of the elastic strip slides through the inner surface of the insertion opening.
[0011] Furthermore, threaded holes are provided on the outer surfaces of the first and second extrusion mounting discs, and bolts are threadedly connected to the threaded holes on the sides of the first and second extrusion mounting discs.
[0012] Furthermore, the outer surfaces of the first and second extrusion mounting discs are covered with a rubber layer.
[0013] Furthermore, the first nut is pressed against the outer surface of the first pressing mounting disc, and the second nut is pressed against the outer surface of the second pressing mounting disc.
[0014] Compared with existing technologies, the advantages of this utility model are:
[0015] (1) When used at a non-specific angle, the connecting pipe is directly supported by an external spring. When it shakes or vibrates, it can be elastically supported by the spring. When it is bent, it can be elastically supported to avoid damage. When a specific angle is required, the connecting pipe can be bent and then positioned by installing an elastic strip structure. The specific angle can be adjusted for use, making it flexible and convenient to use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] Please see Figure 1-5 A flexible connection structure for a pneumatic component includes a connecting pipe 1. The outer end of the connecting pipe 1 is provided with a threaded protrusion 2, which is distributed on the upper and lower end faces of the connecting pipe 1. A first compression mounting plate 4 is fixed to the outer surface of the upper threaded protrusion 2 of the connecting pipe 1 by a first nut 3. A second compression mounting plate 6 is fixed to the outer surface of the lower threaded protrusion 2 of the connecting pipe 1 by a second nut 5. A spring 7 is compression-fixed between the first compression mounting plate 4 and the second compression mounting plate 6, and the spring 7 is sleeved on the outer end of the connecting pipe 1. An elastic strip 8 is installed between the first compression mounting plate 4 and the second compression mounting plate 6. When used at a non-specific angle, the connecting pipe is directly supported by the external spring. During vibration and shaking, the spring provides elastic support, and during bending, it provides elastic support to prevent damage. When a specific angle is required, the elastic strip structure allows the connecting pipe to bend and then be positioned. The specific angle is adjustable, making it flexible and convenient to use.
[0026] The elastic strip 8 adopts a curved strip structure and is made of elastic steel (elastic steel strips usually refer to spring steel, also known as elastic steel. Spring steel is a special type of steel with good elasticity and plasticity).
[0027] The inner surfaces of the outer ends of the first extrusion mounting plate 4 and the second extrusion mounting plate 6 are connected by bolts 9 through threads. The bolts 9 are extruded and fixed to the surface of the elastic strip 8. After the elastic strip 8 is installed, it can be extruded and fixed by the bolts 9. After adjusting the bending angle of the connecting pipe 1, the bolts 9 can be tightened to fix the elastic strip 8. The elastic strip 8 can be positioned after the connecting pipe 1 is bent at an angle. The elastic strip 8 is elastic and can effectively buffer and reduce vibration during vibration.
[0028] The outer surfaces of the first extrusion mounting plate 4 and the second extrusion mounting plate 6 are provided with insertion holes 101, and the outer surface of the elastic strip 8 slides through the inner surface of the insertion hole 101; this facilitates insertion and installation, is convenient to use, and is easy to disassemble.
[0029] The outer surfaces of the first extrusion mounting plate 4 and the second extrusion mounting plate 6 are provided with threaded holes, and the bolt 9 is threadedly connected to the threaded holes on the sides of the first extrusion mounting plate 4 and the second extrusion mounting plate 6; this facilitates installation.
[0030] The outer surfaces of the first extrusion mounting disc 4 and the second extrusion mounting disc 6 are covered with a rubber layer to increase friction.
[0031] The first nut 3 is pressed against the outer surface of the first pressing mounting plate 4, and the second nut 5 is pressed against the outer surface of the second pressing mounting plate 6. When the first nut 3 and the second nut 5 are pressed, they press against the rubber layer on the surface of the pressing mounting plate, which increases the friction of the pressing, making it secure and preventing stripping.
[0032] In use, the threaded protrusions 2 are distributed on the upper and lower end faces of the connecting pipe fitting 1. The outer surface of the threaded protrusion 2 at the upper end of the connecting pipe fitting 1 is fixed with a first compression mounting plate 4 by a first nut 3. The outer surface of the threaded protrusion 2 at the lower end of the connecting pipe fitting 1 is fixed with a second compression mounting plate 6 by a second nut 5. The spring 7 is sleeved on the outer end of the connecting pipe fitting 1. The spring 7 is squeezed and fixed between the first compression mounting plate 4 and the second compression mounting plate 6. The outer surfaces of the first compression mounting plate 4 and the second compression mounting plate 6 are covered with a rubber layer, and the inner end is provided with a positioning ring groove 100. The spring 7 can be locked into the positioning ring groove 100 for positioning. The spring 7 can be locked into the positioning groove 100 for stable support and will not slide back and forth.
[0033] In use, spring 7 is supported on the outer end of connecting pipe 1. After installation, it provides external elastic support. When connecting pipe 1 vibrates, spring 7 provides elastic shock absorption, preventing excessive bending and damage. An elastic strip 8 is installed between the first compression mounting plate 4 and the second compression mounting plate 6. The elastic strip 8 adopts a curved strip structure and is made of elastic steel (elastic steel usually refers to spring steel, also known as elastic steel, which is a special steel with good elasticity and plasticity). Bolts 9 are threadedly connected to the inner surfaces of the outer ends of the first compression mounting plate 4 and the second compression mounting plate 6. Bolts 9 are pressed and fixed to the surface of the elastic strip 8. After installation, the elastic strip 8 can be pressed and fixed by bolts 9. When the connecting pipe 1 is adjusted to a specific angle, the bending angle of the connecting pipe 1 can be adjusted. At this time, the compression mounting plate can slide and bend outside the elastic strip 8. After bending, the bolts 9 can be tightened to fix the elastic strip 8. The elastic strip 8 can be positioned after the connecting pipe 1 is bent at an angle, and the elastic strip 8 is elastic, which can effectively buffer and absorb vibration.
[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
