The fixing connector is rotatably sleeved with the first U-bolt, the second U-bolt, the third U-bolt, and the fourth U-bolt respectively through a first threaded sleeve and a second threaded sleeve.

[0004] Although the device has a clamp to secure the pipe, it is complicated to connect in four sections, requiring alignment four times, which is time-consuming and laborious. Furthermore, the threaded connection may loosen after prolonged use, affecting the tightening quality.

[0005] Therefore, there is a need for a quick-connect clamp for natural gas pipelines that is easy to install. Utility Model Content

[0006] The purpose of this utility model is to provide a quick-connect clamp for natural gas pipelines that is easy to install, in order to solve the problems mentioned in the background art, such as cumbersome, time-consuming and labor-intensive installation and the possibility of loosening after long-term use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect clamp for natural gas pipelines that is easy to install, comprising an outer clamp, a connecting mechanism fixedly installed on the side of the outer clamp, and a ratchet mechanism provided on the top surface of the connecting mechanism; the ratchet mechanism comprises a housing, a fixing plate fixedly installed on the inner wall of the housing, a top block rotatably installed on the side of the fixing plate via a pin, a return spring fixedly installed on the side of the top block, a side plate fixedly installed on the inner wall of the housing, the side of the side plate being fixedly connected to the end face of the return spring, a fixing sleeve fixedly installed on the inner wall of the housing, a guide groove fixedly opened on the inner wall of the fixing sleeve, a limit ring slidably installed on the side of the guide groove, a ratchet fixedly installed on the side of the limit ring, the ratchet tooth surface abutting against the end face of the top block, and a locking slot fixedly opened on the inner wall of the ratchet.

[0008] Preferably, a locking block is installed on the inner wall of the bayonet, a threaded rod is fixedly installed on the side of the locking block, and a nut is fixedly installed on the end face of the threaded rod.

[0009] Preferably, a through hole is fixedly opened on the side of the outer shell, a pin is rotatably installed on the inner wall of the through hole, a knob is fixedly installed on the end face of the pin, a bearing seat is fixedly installed on the other end face of the pin, the end face of the bearing seat is fixedly connected to the inner wall of the outer shell, and an actuating block is fixedly installed on the side of the pin, and the side of the actuating block is in contact with the side of the top block by pressing.

[0010] Preferably, the connecting mechanism includes a first mounting bracket, on the side of which a first anti-slip pad is fixedly mounted, and on the side of the outer hoop a second mounting bracket, on the side of which a second anti-slip pad is fixedly mounted.

[0011] Preferably, an indicator sign is fixedly provided on the side of the outer casing.

[0012] Preferably, the inner wall of the outer hoop is fixedly equipped with six anti-slip pads. A first rubber pad is fixedly installed on one end face of the outer hoop, and a second rubber pad is fixedly installed on the other end face of the outer hoop. The end faces of the first rubber pad and the second rubber pad correspond to each other. A fixing member is fixedly installed on the top face of the first mounting bracket, and the inner wall of the fixing member is fixedly connected to the side of the outer shell.

[0013] Preferably, the number of reset springs is four, and the number of top blocks is two.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) This easy-to-install quick-connect clamp for natural gas pipelines first involves rotating the nut and threaded rod, which in turn rotates the locking block and ratchet. The ratchet then deflects the top block, compressing the return spring and causing the threaded rod to rotate, bringing the second mounting bracket closer to the first mounting bracket. This allows the outer clamp to retract, ensuring a tight connection between the anti-slip pad and the natural gas pipeline. After tightening, turn the knob as indicated by the sign. The knob rotates the pin and the actuating block, pushing out one top block and engaging the ratchet on the other. The engagement of the top block and ratchet prevents the threaded rod from rotating, ensuring the outer clamp remains secure and improving the seal on the natural gas pipeline. This enhances the clamp's tightness, improves installation efficiency, and prevents loosening.

[0016] 2) This easy-to-install quick-connect clamp for natural gas pipelines first involves placing the outer clamp on the connection point of the two natural gas pipelines to be connected. This then causes the anti-slip pads to come into contact with the natural gas pipelines. Next, the ratchet mechanism adjusts the rotation direction of the threaded rod, causing it to rotate further. This rotation of the threaded rod moves the second mounting bracket closer to the first mounting bracket, bringing the first and second anti-slip pads closer together. Simultaneously, the outer clamp contracts, causing the first and second rubber pads to come close together and press against each other, tightening the outer clamp and completing the pipeline connection. This improves the installation speed and sealing quality of the device. Attached Figure Description

[0027] Example 1

[0028] Combination Figures 1-8 A quick-connect clamp for natural gas pipelines that is easy to install, including an outer clamp 1.

[0029] A connecting mechanism 5 is fixedly installed on the side of the outer hoop 1, and a ratchet mechanism 7 is provided on the top surface of the connecting mechanism 5. The ratchet mechanism 7 includes a housing 701, a fixing plate 702 is fixedly installed on the inner wall of the housing 701, a top block 703 is rotatably installed on the side of the fixing plate 702 via a pin, a return spring 704 is fixedly installed on the side of the top block 703, a side plate 705 is fixedly installed on the inner wall of the housing 701, the side of the side plate 705 is fixedly connected to the end face of the return spring 704, a fixing sleeve 706 is fixedly installed on the inner wall of the housing 701, a guide groove is fixedly opened on the inner wall of the fixing sleeve 706, a limit ring 709 is slidably installed on the side of the guide groove, and a limit ring 709 is fixedly installed on the side of the limit ring 709. A ratchet 710 is provided, with its toothed surface abutting against the end face of the top block 703. A slot 711 is fixedly opened on the inner wall of the ratchet 710, and a locking block 714 is installed in the inner wall of the slot 711. A threaded rod 713 is fixedly installed on the side of the locking block 714, and a nut 712 is fixedly installed on the end face of the threaded rod 713. A through hole is fixedly opened on the side of the outer shell 701, and a pin is rotatably installed on the inner wall of the through hole. A knob 707 is fixedly installed on the end face of the pin, and a bearing seat is fixedly installed on the other end face of the pin. The end face of the bearing seat is fixedly connected to the inner wall of the outer shell 701. A toggle block 708 is fixedly installed on the side of the pin, and the side of the toggle block 708 is in contact with the side of the top block 703.

[0030] Specifically, in use, the outer clamp 1 is first fitted onto the side of the natural gas pipeline. Then, the ratchet mechanism 7 is inserted into the connecting mechanism 5. A wrench or lever is used to rotate the threaded rod 713. The rotation of the threaded rod 713 causes the locking block 714 to rotate, which in turn rotates the ratchet 710. At this point, the ratchet 710 deflects the top block 703, compressing the return spring 704 and causing it to rotate. This causes the threaded rod 713 to move closer to the second mounting bracket 503 towards the first mounting bracket 501. The outer clamp 1 can then be retracted, ensuring a tight connection between the anti-slip pad 2 and the natural gas pipeline. After tightening, the knob 707 is turned according to the indicator 715. The knob 707 rotates the pin and the actuating block 708, pushing out one top block 703. The other top block 703 then contacts the ratchet 710. The interaction between the top block 703 and the ratchet 710 prevents the threaded rod 713 from rotating, ensuring the outer clamp 1 does not loosen and improving the sealing of the natural gas pipeline.

[0031] Example 2

[0032] See Figures 1-8 Furthermore, the connecting mechanism 5 includes a first mounting bracket 501, a first anti-slip pad 502 fixedly mounted on the side of the first mounting bracket 501, a second mounting bracket 503 fixedly mounted on the side of the outer hoop 1, a second anti-slip pad 504 fixedly mounted on the side of the second mounting bracket 503, an indicator sign 715 fixedly mounted on the side of the outer shell 701, six anti-slip pads 2 fixedly mounted on the inner wall of the outer hoop 1, a first rubber pad 3 fixedly mounted on one end face of the outer hoop 1, a second rubber pad 4 fixedly mounted on the other end face of the outer hoop 1, the end faces of the first rubber pad 3 and the second rubber pad 4 corresponding to each other, a fixing member 6 fixedly mounted on the top surface of the first mounting bracket 501, the inner wall of the fixing member 6 fixedly connected to the side of the outer shell 701, four return springs 704, and two top blocks 703.

[0033] Specifically, in use, the outer clamp 1 is first placed on the connection point of the two natural gas pipelines to be connected, which further drives the anti-slip pad 2 to fit against the natural gas pipeline. The rotation direction of the threaded rod 713 is then adjusted by the ratchet mechanism 7, which further drives the threaded rod 713 to rotate. At this time, the rotation of the threaded rod 713 drives the second mounting bracket 503 to move closer to the first mounting bracket 501. At this time, the first anti-slip pad 502 and the second anti-slip pad 504 move closer together. At the same time, the outer clamp 1 contracts, and the first rubber pad 3 and the second rubber pad 4 move closer together and squeeze, thus tightening the outer clamp 1 and completing the connection of the pipeline.
