Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a novel fiberglass quick connector. Background Technology

[0002] Fiberglass reinforced plastic (FRP) materials are widely used in many fields of modern industry and construction due to their excellent properties such as lightweight, high strength, corrosion resistance, and insulation. In various practical applications, it is often necessary to connect FRP components to build complete systems or structures. For example, in the laying of chemical pipelines, the installation of building water supply and drainage facilities, and the assembly of large FRP equipment, the connection between FRP components is a crucial link.

[0003] Traditional fiberglass connectors, achieved through threads or mechanical connections, struggle to maintain stability under external vibrations, impacts, or torque. In areas near operating machinery, earthquake-prone regions, or pipeline systems subjected to significant fluid impacts, traditional connectors are susceptible to loosening, displacement, or even breakage due to external disturbances, leading to system malfunctions or safety incidents. Therefore, a novel fiberglass quick-connect connector is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a new type of fiberglass quick-connect connector, which aims to improve the problem that the connector in the prior art is prone to loosening due to external interference.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel fiberglass quick-connect connector, comprising a connector body and a fixing tube, wherein the inner wall of the connector body is provided with a threaded groove, the inner wall of the threaded groove is provided with a locking component, the outer wall of the fixing tube is provided with threads, and a positioning component is provided on the side of the fixing tube near the connector body;

[0006] The engaging assembly includes a fixing plate, which is fixedly connected to the inner wall of the connector body. A mounting plate is fixedly connected to the side of the fixing plate near the fixing tube. Multiple spring plates are fixedly connected to the outer wall of the mounting plate along the circumferential direction.

[0010] The outer wall thread of the fixed tube is threadedly connected to the inner wall thread groove of the connector body.

[0011] As a further description of the above technical solution:

[0012] Both the spring sheet and the fixing groove are square in shape.

[0013] As a further description of the above technical solution:

[0014] The spring sheet and the mounting plate are an integral structure, and the spring sheets are evenly distributed.

[0015] As a further description of the above technical solution:

[0016] The fixing grooves are formed in the circumferential direction of the stabilizing plate, and the fixing grooves are equidistantly distributed.

[0017] As a further description of the above technical solution:

[0018] The depth of the fixing groove is equal to the width of the spring sheet, and the fixing groove matches the spring sheet.

[0019] As a further description of the above technical solution:

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Reference Figure 1-Figure 3 This utility model provides an embodiment of a novel fiberglass quick-connect connector, comprising a connector body 1 and a fixing tube 3. The inner wall of the connector body 1 has a threaded groove 2, and an engaging component is provided on the inner wall of the threaded groove 2. The outer wall of the fixing tube 3 has threads 4. By providing the threaded groove 2, it can engage with the threads 4 on the outer wall of the fixing tube 3. During the connection process, when the fixing tube 3 is screwed into the connector body 1, the threaded groove 2 provides a precise guiding path for the fixing tube 3, allowing it to stably enter the connector body 1 along a predetermined trajectory. A positioning component is provided on the side of the fixing tube 3 near the connector body 1.

[0031] Reference Figure 2 and Figure 3 The engaging assembly includes a fixing plate 5, which is fixedly connected to the inner wall of the connector body 1. The fixing plate 5 stably fixes the engaging assembly in a specific position inside the connector body 1, providing a solid foundation for the subsequent mounting plate 6 and spring plates 7, ensuring the stability and reliability of the overall structure of the engaging assembly. The mounting plate 6 is fixedly connected to the side of the fixing plate 5 near the fixing tube 3. The mounting plate 6 serves as the carrier of the spring plates 7, enabling the spring plates 7 to be evenly distributed on its surface and ensuring that the spring plates 7 are in the appropriate position. Multiple spring plates 7 are fixedly connected to the outer wall of the mounting plate 6 along the circumferential direction. The multiple spring plates 7 are distributed along the circumferential direction, and can contact and cooperate with the positioning component from multiple angles when the fixing tube 3 is screwed into the connector body 1 and approaches the positioning component, forming an all-round engaging effect, which greatly improves the connection stability and anti-torsion performance of the connector, and effectively prevents the connector from loosening or detaching under external vibration, impact or complex stress conditions.

[0032] Reference Figure 2 and Figure 3 The positioning component includes a stabilizing plate 8, which is fixedly connected to the side of the fixing tube 3 near the connector body 1. The stabilizing plate 8 provides a foundation for the fixing groove 9 and has sufficient strength and stability to withstand the force from the spring plate 7 and other external forces during connection and use. The outer wall of the stabilizing plate 8 has multiple fixing grooves 9, which are matched with the spring plate 7. When the fixing tube 3 is screwed into the connector body 1, the spring plate 7 can be accurately inserted into the fixing groove 9, thereby achieving precise positioning and locking of the connector body 1 and the fixing tube 3 in the circumferential direction.

[0033] Reference Figure 1 and Figure 2 The threaded connection between the outer thread 4 of the fixed pipe 3 and the threaded groove 2 of the inner wall of the connector body 1 is a threaded connection. The connection between the fixed pipe 3 and the connector body 1 can be achieved simply by rotating the fixed pipe 3. This operation is simple and quick, requiring no complex installation tools or cumbersome installation processes, greatly improving connection efficiency and reducing installation costs. Furthermore, the threaded connection provides a greater connection force, ensuring the connector maintains a tight connection even under certain internal pressure and external tension, effectively preventing media leakage and ensuring the reliability and safety of the connection under various working conditions.

[0034] Reference Figure 2 and Figure 3 Both the spring plate 7 and the fixing groove 9 are square in shape. The square shape design makes the fit between the spring plate 7 and the fixing groove 9 tighter and more stable. Compared with other shapes, the square edges can effectively limit the movement range of the spring plate 7 in the groove after it is inserted into the fixing groove 9, preventing excessive displacement or rotation when subjected to external forces. This further improves the stability and reliability of the joint connection, ensuring that the connection structure can maintain good performance during long-term use.

[0035] Reference Figure 2 and Figure 3 The spring plate 7 and the mounting plate 6 are an integral structure. The integral structure design avoids the problem of connection gaps or weak connections between the spring plate 7 and the mounting plate 6, and improves the overall structural strength and reliability of the snap-fit ​​assembly. In addition, the spring plates 7 are evenly distributed. The evenly distributed spring plates 7 can evenly bear and transmit the force when they are engaged with the fixing groove 9, avoiding excessive local stress caused by uneven force, thereby extending the service life of the joint and improving the adaptability of the joint under various complex stress conditions.

[0036] Reference Figure 2 and Figure 3The fixing groove 9 is opened in the circumferential direction of the stabilizing plate 8. The circumferential setting of the fixing groove 9 matches the circumferential distribution of the spring plate 7, which can achieve all-round positioning and locking effect. The fixing groove 9 is evenly distributed, which ensures that the spring plate 7 is subjected to uniform force when inserted, so that the connector body 1 and the fixing tube 3 can maintain good coaxiality during the connection process, reduce the wear or damage of the connecting parts caused by eccentric force, improve the accuracy and stability of the connection, and help the connecting joint maintain stable performance during long-term operation.

[0037] Reference Figure 2 and Figure 3 The depth of the fixing groove 9 is equal to the width of the spring plate 7. The size matching relationship ensures that after the spring plate 7 is inserted into the fixing groove 9, it will not easily fall out due to the shallow depth, nor will it cause the spring plate 7 to shake in the groove or fail to fully exert its locking function due to the deep depth. Moreover, the fixing groove 9 and the spring plate 7 are matched. When the spring plate 7 and the fixing groove 9 are perfectly matched, a stable locking structure can be formed in the circumferential direction, which effectively prevents the relative rotation and displacement between the connector body 1 and the fixing tube 3, ensuring the reliability and sealing of the connection. Even when subjected to large external forces or internal pressure fluctuations, the connection can maintain a stable state.

[0038] Reference Figure 1-Figure 3 The connector body 1, fixing tube 3, spring plate 7, and stabilizing plate 8 are all made of soda-lime glass. Soda-lime glass possesses certain mechanical strength and chemical stability, meeting the requirements of the connector under general working conditions. Its manufacturing cost is relatively low, which is conducive to large-scale production and widespread application. Furthermore, soda-lime glass has good processing performance, allowing for the easy fabrication of complex-shaped components such as the connector body 1 and fixing tube 3, as well as the machining of fine structures like threaded grooves 2 and fixing grooves 9 on its surface, ensuring the manufacturing precision and quality of the connector.

[0039] Working Principle: When the pipeline is damaged by external pressure or other factors, it is cut off. Then, the fixing pipe 3 and the connector body 1 are welded to the two cut pipe joints respectively. During the connection operation, the threaded end 4 of the fixing pipe 3 is first aligned with the threaded groove 2 on the inner wall of the connector body 1. Due to the design of the thread 4 and the threaded groove 2, when a rotational force is applied to the fixing pipe 3, it can gradually screw into the connector body 1 along the spiral path defined by the threaded groove 2. During this process, the stabilizing plate 8 on the side of the fixing pipe 3 closest to the connector body 1 also moves closer to the inside of the connector body 1, reducing the number of times the pipeline needs to be replaced and saving costs.

[0040] Meanwhile, multiple spring plates 7 located inside the connector body 1 and fixed to the inner wall of the connector body 1 by the fixing plate 5 and supported by the mounting plate 6 are in a waiting-to-fit state. As the fixing tube 3 is screwed in, when the stabilizing plate 8 reaches the position of the spring plate 7, due to the elasticity of the spring plate 7, the spring plate 7 will undergo elastic deformation and open outward under the compression of the stabilizing plate 8.

[0041] As the fixing tube 3 continues to screw in until it reaches the predetermined position, the spring plate 7 is precisely aligned with the fixing groove 9 on the outer wall of the stabilizing plate 8. At this point, the spring plate 7 quickly inserts into the fixing groove 9 under the action of its own elastic restoring force. Since both the spring plate 7 and the fixing groove 9 are square in shape and their depth and width match each other, the spring plate 7 can be tightly engaged in the fixing groove 9, thereby achieving precise positioning and locking of the connector body 1 and the fixing tube 3 in the circumferential direction.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
