Description

Technical Field

[0001] This utility model belongs to the field of pipe joints, specifically relating to a combined stainless steel slip-on joint. Background Technology

[0002] A union, also known as a swivel or union, is a common pipe fitting used in industry and daily life that facilitates easy installation and disassembly, making pipe connections simpler. Industrial threaded unions are generally made of metal with high pressure resistance, and materials include carbon steel, stainless steel, alloy steel, and brass; domestic threaded unions are generally made of materials such as PC, PVC, and PE.

[0003] Existing nuts connect directly to the threads on the outer wall of the pipe fitting via the threads on the inner wall of the nut, providing a locking mechanism for the pipe fitting. However, the existing threaded connection method is prone to vibration during use, which can cause the nut to gradually loosen and come off due to the vibration of the external operating environment. This can lead to the nut coming off lock in the opposite direction of the thread rotation, resulting in the sealing state being compromised and the internal medium leaking out. Therefore, a combined stainless steel slip-fitting joint is proposed to solve the above-mentioned problems. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-3 In this embodiment, the combined stainless steel slip-on joint, through the connection structure formed by the plug-in 6 and the fixing member 7, can strengthen the fixed state between the nut 1 and the pipe joint 2, and prevent the nut 1 and the pipe joint 2 from loosening and leaking.

[0021] Specifically, it includes a nut 1 and a pipe fitting 2. The inner wall of the nut 1 and the outer wall of the pipe fitting 2 are respectively threaded, and the nut 1 and the pipe fitting 2 are detachably connected by the threads.

[0022] The sealing ring 3 is embedded in the insertion end of the pipe fitting 2 to achieve a seal between the nut 1 and the pipe fitting 2;

[0023] Several grooves 4 are formed in a ring on the outer wall of the nut 1;

[0024] Several sliders 5 are slidably disposed in corresponding grooves 4; each slider 5 is provided with a connector 6, and both the grooves 4 and the sliders 5 are T-shaped.

[0025] Several fasteners 7 are arranged in a ring on the outer wall of the pipe joint 2; the plug-in 6 is used to fix the position of the slider 5 and can be plugged into the fasteners 7 to maintain the fixed state between the nut 1 and the pipe joint 2.

[0026] In this embodiment, before use, the nut 1 and pipe fitting 2 need to be connected to the external pipeline by welding or fusion. Then, the nut 1 and pipe fitting 2 are joined together and screwed on to finally compress the sealing ring 3, thus completing the connection between the two pipe sections. After the connection is completed, the slider 5 can be pulled to slide inside the groove 4 to adjust the plug 6 to be aligned with the fixing part 7. Then, one end of the plug 6 is inserted into the fixing part 7. Through the connection structure formed by the plug 6 and the fixing part 7, the fixed state between the nut 1 and pipe fitting 2 can be reinforced, preventing the nut 1 and pipe fitting 2 from loosening and leaking. The adjustable position design of the slider 5, compared with the fixed structure, eliminates the need to rotate the nut 1 to a specific position to align the plug 6 with the fixing part 7, making it more convenient and faster to use.

[0027] Specifically, refer to Figure 2 The connector 6 includes a fixing plate 61 mounted on the slider 5; a fixing screw 62 mounted on the fixing plate 61, which abuts against the nut 1 to fix the position of the fixing plate 61; a fixing bracket 63 mounted on the fixing plate 61; an insert plate 64 slidably inserted into the fixing bracket 63 at one end; and a fixing screw 65 mounted on the fixing bracket 63, which abuts against the insert plate 64 to fix one end of the insert plate 64.

[0028] Specifically, refer to Figure 2 The fastener 7 includes a second fastener 71 mounted on the outer wall of the pipe connector 2, and the other end of the insert plate 64 can be slidably inserted into the second fastener 71; and a third fastener 72 mounted on the second fastener 71, which abuts against the insert plate 64 and is used to fix the other end of the insert plate 64.

[0029] In this embodiment, after aligning the first fixing bracket 63 and the second fixing bracket 71 using the slider 5, the first fixing screw 62 can be screwed until it contacts the outer wall of the nut 1 to fix the slider 5 in its current position. Then, the two ends of the insert plate 64 are inserted into the first fixing bracket 63 and the second fixing bracket 71 respectively, and the third fixing screw 72 and the second fixing screw 65 are screwed on. This fixes the two ends of the insert plate 64 into the first fixing bracket 63 and the second fixing bracket 71 respectively. The support structure formed by the insert plate 64 can reinforce the fixing state between the nut 1 or the pipe joint 2, preventing the nut 1 or the pipe joint 2 from reversing and causing leakage. At the same time, the design of the insert plate 64 being combinable or detachable from the first fixing bracket 63 and the second fixing bracket 71 not only allows the user to freely rotate whether reinforcement is needed, making it more flexible to use, but also does not affect the external pipe wrench for clamping and tightening the nut 1 and the pipe joint 2 when using them, making it convenient to use.

[0030] Specifically, refer to Figure 1 and Figure 3 The outer wall of the nut 1 has a groove 8, and a toothed ring 9 is provided inside the groove 8. One end of the fixing screw 62 is inserted into the groove 8 and abuts against the toothed ring 9.

[0031] In this embodiment, when the fixing screw 62 is inserted into the insertion groove 8 and contacts the toothed ring 9, the fixing screw 62 abuts against the toothed plane on the toothed ring 9. By limiting the corner of the toothed ring 9, the current position of the fixing screw 62 can be reinforced to prevent the displacement of the slider 5 from affecting the support state of the insert plate 64.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
