Description

Technical Field

[0001] This application relates to the technical field of connectors, and in particular to an internal threaded connector with a limiting structure. Background Technology

[0002] Pre-embedded pipes are a common construction method in the construction industry. The ends of pre-embedded pipes are mainly connected to external pipes or water appliances by means of heat fusion joints. Heat fusion joints achieve the connection by heating the pipe ends and joints, melting them, quickly inserting them, and then cooling and solidifying them.

[0003] In related technologies, the connector includes a connector body, which is used to connect with a pipeline. The connector body has a perforation for fluid to pass through, and an insertion end is provided on the connector body for fixing the connector body.

[0004] When workers install the connector, the lack of an effective limiting structure between the connector body and the pipe end makes the connector body prone to shaking, thus making it impossible to accurately control the angle of the connector. Utility Model Content

[0005] To improve the problem of uncontrollable joint angle, this application provides an internal threaded joint with a limiting structure.

[0006] This application provides an internal threaded connector with a limiting structure, which adopts the following technical solution:

[0007] An internal threaded connector with a limiting structure includes a connector body for connecting to a pipe, a through hole for fluid passage, an insertion end for fixing the connector body, a limiting part on the connector body, and a limiting groove on a wall for insertion of the limiting part; when the limiting part is inserted into the limiting groove, the connector body is mounted on the wall.

[0008] By adopting the above technical solution, when the workers install the connector body, the angle between the connector body and the pipeline is fixed by inserting the limiting part into the limiting groove. The workers can control the angle of the connector to ensure that the angle direction of the connector body is correct, thereby reducing the installation deviation of the connector.

[0009] Optionally, a baffle is provided on the outer surface of the connector body; when the baffle abuts against the wall, the limiting part is inserted into the limiting groove.

[0010] By adopting the above technical solution, a baffle is provided on the outer surface of the connector body. The baffle abuts against the wall, thereby fixing the connector body to the wall, reducing the possibility of the connector body shaking, thus improving the stability of the connector and facilitating the subsequent installation of another pipe connector or water appliance by the staff.

[0011] Optionally, the connector body is provided with an internal thread insert for threaded connection to external pipes or water appliances. The internal thread insert has a through hole that communicates with a perforation hole. The outer surface of the internal thread insert is provided with a retaining ring, and the inner surface of the connector body is provided with a ring groove for the retaining ring to be inserted. When the retaining ring is inserted into the ring groove, the internal thread insert is installed on the connector body.

[0012] By adopting the above technical solution, with the internal thread insert on the connector body, another pipe connector or water appliance can be threaded onto the connector body, thereby improving the firmness between the connector body and the other pipe connector; by inserting the fixing ring into the ring groove, the internal thread insert and the connector body are fixed.

[0013] Optionally, the internal thread insert is provided with a fixing part, and the distance from the fixing part to the axis of the connector body is less than the distance from the inner wall of the perforation to the axis.

[0014] By adopting the above technical solution, the fluid in the pipeline enters the through hole from the perforation. Since the distance from the fixing part to the axis of the connector body is less than the distance from the inner wall of the pipeline to the axis, the fluid flows in the direction of the axis of the connector body, which increases the flow velocity of the fluid towards the internal thread insert. At the same time, it reduces the possibility of the fluid flowing along the gap between the internal thread insert and the perforation wall.

[0015] Optionally, the outer surface of the internal thread insert is provided with a locking block, and the wall of the through hole is provided with a slot for the locking block to be inserted; when the locking block is inserted into the slot, the internal thread insert is fixed to the connector body.

[0016] By adopting the above technical solution, when the card block is inserted into the card slot, the internal thread insert and the connector body are fixed. The operator can disassemble or install the internal thread insert and adapt different pipe connectors by replacing different internal thread inserts, thereby enhancing the applicability of the connector.

[0017] Optionally, the slot is provided with a spring block located on the slot wall; when the card block is inserted into the slot, the spring block abuts against the card block, and the spring block deforms.

[0018] By adopting the above technical solution, when the card block is inserted into the card slot, the spring block deforms and exerts a force on the card block, making the internal thread insert more firmly fixed in the connector body, thereby reducing the possibility of the internal thread insert detaching from the connector body.

[0019] Optionally, the connector body has a fixing hole, the locking block has a limiting hole, and a fixing rod is slidably connected in the fixing hole. When the internal threaded insert is installed on the connector body, the fixing rod is inserted into the limiting hole through the fixing hole.

[0020] By adopting the above technical solution, when the internal thread insert is installed on the connector body, the fixing rod passes through the fixing hole and is inserted into the limiting hole, so that the internal thread insert can be more tightly fixed on the connector body, thereby preventing the internal thread insert from detaching from the connector body due to fluid impact or human action.

[0021] Optionally, a fixing groove is provided on the groove wall of the card slot, the fixing groove is connected to the fixing hole, and the fixing rod is provided with an elastic protrusion. When the fixing rod is inserted into the fixing groove, the protrusion abuts against the groove wall of the fixing groove and the card block respectively.

[0022] By adopting the above technical solution, when the fixing rod is inserted into the fixing groove, the protrusions abut against the groove wall and the locking block respectively, so that the fixing rod can be fixed in the fixing groove, thereby reducing the possibility of the fixing rod coming out of the limiting hole.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the worker installs the connector body, by inserting the limiting part into the limiting groove, the angle between the connector body and the pipeline is fixed. The worker can control the angle of the connector to ensure that the angle direction of the connector body is correct, thereby reducing the installation deviation of the connector.

[0025] 2. A baffle is provided on the outer surface of the connector body. The baffle abuts against the wall, which fixes the connector body to the wall, reduces the possibility of the connector body shaking, and thus improves the stability of the connector, making it easier for workers to install another pipe connector or water appliance later.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0035] Example 1

[0036] This embodiment discloses an internal threaded connector with a limiting structure. (Refer to...) Figure 1 and Figure 2 An internal threaded connector with a limiting structure includes a connector body 1, which is made of high-temperature and corrosion-resistant engineering plastic, such as PVC or PPR material, and is used to connect to a pipe.

[0037] Reference Figure 2 and Figure 3 The connector body 1 has a through hole 16 for fluid passage on its end face, and an insertion end 2 is integrally formed on the end face of the connector body 1. The insertion end 2 is fixed to the connector body 1 and the pipeline by heat fusion. A baffle 11 is fixedly connected to the outer surface of the connector body 1, and the baffle 11 is perpendicular to the length direction of the connector body 1.

[0038] Reference Figure 2 and Figure 3 A limiting part 12 is fixedly connected to the surface of the baffle 11 near the insertion end 2. The limiting part 12 is perpendicular to the baffle 11 and extends towards the insertion end 2. A limiting groove 121 is provided on the wall for the limiting part 12 to be inserted. When the limiting part 12 is fully inserted into the limiting groove 121, the baffle 11 abuts against the wall, and the outer surface of the insertion end 2 abuts against the inner surface of the pipe, thus the connector body 1 is installed on the wall.

[0039] Reference Figure 2 and Figure 3The connector body 1 has a detachably connected internally threaded insert 3 on the side away from the insertion end 2, and the connector body 1 is fitted onto the outer surface of the internally threaded insert 3. The internally threaded insert 3 has a through hole 31, which communicates with the through hole 16 and allows fluid to pass through. The internally threaded insert 3 is made of stainless steel and is used for threaded connection to external pipes or water appliances.

[0040] Reference Figure 2 and Figure 3 A ring-shaped fixing ring 32 is fixedly connected to the outer surface of the internal thread insert 3. Multiple fixing rings 32 are provided. Multiple limiting rings are arranged in an array along the length direction of the connector body 1. Multiple ring grooves 13 are opened on the inner surface of the connector body 1, and each ring groove 13 is for the corresponding limiting ring to be inserted.

[0041] Reference Figure 3 A fixing part 311 is integrally formed inside the through hole 31. The fixing part 311 is annular, and its inner diameter is smaller than that of the through hole 16. When fluid flows from the through hole 16 to the through hole 31, the fluid velocity increases as it passes through the fixing part 311.

[0042] Reference Figure 2 and Figure 4 A locking block 33 is fixedly connected to the outer surface of the internally threaded insert 3, and the locking block 33 extends along the length direction of the internally threaded insert 3. Multiple locking blocks 33 are arranged in an array along the circumferential surface of the internally threaded insert 3. A slot 34 for inserting the locking block 33 is formed on the wall of the through hole 31. Multiple slots 34 extend along the length direction of the connector body 1, and are arranged in an array along the circumferential surface of the connector body 1. When the connector body 1 is installed on a wall, each locking block 33 is inserted into its corresponding slot 34, and the internally threaded insert 3 is fixed to the connector body 1.

[0043] The implementation principle of Example 1 is as follows: the worker first inserts the limiting part 12 into the limiting groove 121 to determine the angle of the connector body 1, then the baffle 11 abuts against the wall to realize the connection between the connector body 1 and the pipe, and at the same time inserts the locking block 33 on the internal thread insert 3 into the locking groove 34 to realize the fixation between the internal thread insert 3 and the connector body 1.

[0044] Example 2

[0045] Reference Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that each of the multiple slots 34 has a spring block 341 fixedly connected to its surface away from the axis of the connector body 1, and the spring block 341 is located on the moving path of the slot block 33. When the connector body 1 is installed on the wall, the slot block 33 is inserted into the slot 34, and the spring block 341 is located between the slot block 33 and the slot wall of the slot 34, at which time the spring block 341 deforms.

[0046] Reference Figure 7 A fixing hole 14 is provided on the outer surface of the connector body 1, and a limiting hole 331 for communicating with the fixing hole 14 is provided on the locking block 33. A fixing rod 15 is slidably connected in the fixing hole 14 of the locking groove 34, and the fixing rod 15 slides in the vertical direction. A fixing groove 342 is provided on the groove wall of the locking groove 34 near the axis of the connector body 1, and the width of the fixing groove 342 is greater than the diameter of the limiting hole 331. The fixing rod 15 can pass through the fixing hole 14 and the limiting hole 331 in sequence and be inserted into the fixing groove 342. The length of the fixing rod 15 is greater than the distance from the bottom wall of the fixing groove 342 to the outer surface of the connector body 1.

[0047] Reference Figure 6 and Figure 7 The outer surface of the fixing rod 15 is fixedly connected with an elastic protrusion 151. When the fixing rod 15 is inserted into the fixing groove 342, the protrusion 151 abuts against the groove wall of the fixing groove 342 near the insertion end 2 and the surface of the locking block 33 near the fixing groove 342 respectively. At this time, the protrusion 151 does not deform.

[0048] The implementation principle of Example 2 is as follows: The worker aligns the locking block 33 on the internal thread insert 3 with the locking groove 34 and inserts it. At this time, the spring block 341 deforms. Then, the worker inserts the fixing rod 15 into the limiting groove 121 through the fixing hole 14 and the limiting hole 331 in sequence. At this time, the protrusion 151 does not deform, and the internal thread insert 3 and the connector body 1 are fixed.
