Description

Technical Field

[0001] This utility model relates to the field of straight pipe connector technology, and in particular to a quick-connect straight pipe connector. Background Technology

[0002] Straight pipes are a very common type of flow channel structure in daily life. If a straight pipe breaks during use, a straight pipe connector is usually used to splice it.

[0003] Currently, existing straight-through pipe joints require the inner wall of one end of the joint to be hot-bonded to the end of one of the straight pipes at the cut point before installation. This is not only time-consuming and labor-intensive but also affects installation efficiency. Therefore, in order to achieve faster connection of straight-through pipe joints, further advance industry technology, and improve core technology competitiveness, this application proposes a new implementation scheme that differs from existing straight-through pipe joints and application methods. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing straight pipe connectors require hot-bonding one end of the connector to the end of one of the straight pipes at the cut point before installation, which is not only time-consuming and labor-intensive but also affects the efficiency of installation. Therefore, a quick-connect straight pipe connector is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-connect straight pipe fitting includes a straight pipe fitting and two straight pipes. The straight pipe fitting includes a connecting sleeve and a threaded connecting pipe. The connecting sleeve is fitted onto one end of the straight pipe, and one end of the connecting sleeve has an installation groove. The threaded connecting pipe is threaded between the two installation grooves. One side of the inner wall of the installation groove has an installation ring, and one side of the installation ring has a clamping ring. Both the clamping ring and the installation ring have multiple installation holes. Fastening screws are inserted into the installation holes, and one end of the fastening screw is threaded to one side of the inner wall of the installation groove. The small-diameter end of the clamping ring is fitted onto one end of the straight pipe, and multiple anti-slip protruding rings are fixedly connected to the inner wall of the clamping ring. Both ends of the threaded connecting pipe have annular grooves, and the small-diameter end of the clamping ring can be inserted into the annular grooves. One end of the threaded connecting pipe is fixedly connected to an annular pressure block, which presses against the outer surface of the small-diameter end of the clamping ring.

[0007] Furthermore, the clamping ring is a rubber ring, and the clamping ring has a trumpet-shaped structure.

[0008] Furthermore, the outer circumferential wall of the connecting sleeve is fixedly connected with multiple anti-slip protrusions.

[0009] Furthermore, a first hexagonal block is fixedly connected to the outer circumferential wall of the connecting sleeve.

[0010] Furthermore, a second hexagonal block is fixedly connected to the outer circumference of the threaded connecting pipe.

[0011] Furthermore, a sealing ring is provided between the connecting sleeve and the threaded connecting pipe.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By fitting the clamping ring onto one end of the straight pipe, the connecting sleeve is connected to the straight pipe. Then, the threaded connecting pipe is inserted into the mounting grooves of the two connecting sleeves and tightened. During this process, the annular pressure block will squeeze the clamping ring, making the clamping ring fit more tightly onto the straight pipe, thereby quickly and firmly connecting the straight pipe and the straight pipe joint, eliminating the hot-sticking step and improving the connection efficiency.

[0014] 2. The anti-slip convex ring increases friction, prevents loosening of the connection, ensures the stability and airtightness of the connection, and improves the connection effect between straight pipes and straight pipe joints.

[0015] 3. The arrangement of the first and second hexagonal blocks provides an interface that facilitates tightening and loosening using wrenches or socket tools, thus improving the ease of operation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A quick-connect straight pipe fitting includes a straight pipe fitting and two straight pipes 8. The straight pipe fitting includes a connecting sleeve 1 and a threaded connecting pipe 11. The connecting sleeve 1 is fitted onto one end of the straight pipe 8, and one end of the connecting sleeve 1 has a mounting groove 2. The threaded connecting pipe 11 is threaded between the two mounting grooves 2. A mounting ring 4 is provided on one side of the inner wall of the mounting groove 2, and a clamping ring 3 is provided on one side of the mounting ring 4. Both the clamping ring 3 and the mounting ring 4 have multiple mounting holes 6. Fastening screws 5 are inserted into the mounting holes 6, and one end of the fastening screw 5 is threaded to one side of the inner wall of the mounting groove 2. The small-diameter end of the clamping ring 3 is fitted onto one end of the straight pipe 8, and the inner wall of the clamping ring 3 is integrally formed with multiple anti-slip protrusions 7. The anti-slip protrusions 7 increase friction and prevent the connection from loosening. To ensure the stability and airtightness of the connection, both ends of the threaded connecting pipe 11 are provided with annular grooves 12. The small-diameter end of the clamping ring 3 can be inserted into the annular groove 12. One end of the threaded connecting pipe 11 is integrally formed with an annular pressure block 13. The annular pressure block 13 presses on the outer surface of the small-diameter end of the clamping ring 3. The connecting sleeve 1 is put on one end of the straight pipe 8, and the small-diameter end of the clamping ring 3 is also put on the straight pipe 8, thereby connecting the connecting sleeve 1 and the straight pipe 8 together. Then, the threaded connecting pipe 11 is inserted into the mounting grooves 2 of the two connecting sleeves 1 and tightened. During this process, the annular pressure block 13 will squeeze the clamping ring 3, thereby making the clamping ring 3 fit more tightly on the straight pipe 8, thus quickly and steadily achieving the connection between the straight pipe 8 and the straight pipe connector.

[0024] The clamping ring 3 is a rubber ring and has a flared structure with a large diameter at one end and a small diameter at the other end. The outer circumference of the connecting sleeve 1 is integrally formed with multiple anti-slip protrusions 9. The anti-slip protrusions 9 can increase the friction coefficient of the operator during installation and disassembly, making it easier to operate manually.

[0025] The outer circumferential wall of the connecting sleeve 1 is integrally formed with a first hexagonal block 10, and the outer circumferential wall of the threaded connecting pipe 11 is integrally formed with a second hexagonal block 15. The first hexagonal block 10 and the second hexagonal block 15 provide an interface that facilitates tightening and disassembly using a wrench or socket tool, thereby improving the ease of operation.

[0026] A sealing ring 14 is provided between the connecting sleeve 1 and the threaded connecting pipe 11. The sealing ring 14 further enhances the sealing of the connection and prevents media leakage.

[0027] The working principle of this embodiment is as follows: In use, firstly, the connecting sleeve 1 is put on one end of the straight pipe 8. At this time, the small diameter end of the clamping ring 3 is also put on this end of the straight pipe 8, thereby connecting the connecting sleeve 1 and the straight pipe 8 together. Then, the threaded connecting pipe 11 is inserted into the mounting groove 2 of the two connecting sleeves 1 and tightened. During the tightening process, the annular pressure block 13 will squeeze the clamping ring 3, thereby making the clamping ring 3 fit more tightly on the straight pipe 8. At this time, the small diameter end of the clamping ring 3 will be inserted into the annular groove 12, thereby quickly and steadily realizing the connection between the straight pipe 8 and the straight pipe connector.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
