Description

Technical Field

[0001] This application relates to the field of pipe installation devices, and more particularly to an installer for socket-joint pipes. Background Technology

[0002] Socket-joint pipes are pipe fittings that connect pipes through the nested fit of a socket and a spigot. Socket-joint pipes consist of a pipe and a socket fitting. Installation of socket-joint pipes requires using a hand-operated lever to insert the fitting into one end of the pipe, which is a cumbersome and difficult process, especially when installing elbows. Therefore, improvements are needed. Utility Model Content

[0003] To facilitate the installation of socket-joint pipes, this application provides an installer for socket-joint pipes.

[0004] The installer for socket joint pipes provided in this application adopts the following technical solution:

[0005] An installer for socket-type pipes includes two mounting components and two tightening straps. The two mounting components are arranged opposite to each other. Each mounting component includes a sliding seat, a connector, a force-applying rod, a first pawl, and a torsion spring. The sliding seat includes a sliding block and a first abutment plate, the first abutment plate being disposed on one side of the sliding block. The connector includes a rack, a gear, and a second abutment plate. The rack is slidably connected to the sliding block, the gear is rotatably connected to the sliding block and meshes with the rack, and the second abutment plate is disposed on the side of the rack near the first abutment plate. The force-applying rod is rotatably connected to both sides of the sliding block, the first pawl is rotatably connected to the force-applying rod, and the torsion spring is disposed between the first pawl and the force-applying rod to drive the first pawl to abut against the gear. The two tightening straps are spaced apart along the length of the rack, and the tightening straps are used to connect the two sliding blocks or the two racks.

[0006] By adopting the above technical solution, in practical applications, the socket fitting is first pre-installed on one end of the pipe. Two installation components are located on both sides of the pipe and the socket fitting. The first abutment plate abuts against the periphery of the pipe, and the second abutment plate abuts against the periphery of the socket fitting. One tightening band fixes two sliding blocks, and the other tightening band fixes two racks. Since the torsion spring drives the first pawl to abut against the gear, by rotating the force rod, the first pawl drives the gear to rotate, thereby driving the meshing racks to move, so that the socket fitting moves towards the end closer to the pipe, thus realizing the installation of the socket fitting on the pipe. The operation is simple and convenient, thereby facilitating the installation of socket joint pipes.

[0007] Preferably, the sliding seat further includes a first threading frame, which is disposed between the sliding block and the first abutment plate for the tightening strap to pass through.

[0008] By adopting the above technical solution, by setting a first threading frame, and by threading a tightening strap through the first threading frame, the pipe is more stably clamped between the two first abutment plates, thereby improving the stability of the socket joint pipe installation.

[0009] Preferably, the connector further includes a second threading frame, which is disposed between the rack and the second abutment plate for the tightening strap to pass through.

[0010] By adopting the above technical solution, by setting a second threading frame, and by threading a tightening strap through the second threading frame, the socket fitting is more stably clamped between the two second abutment plates, thereby improving the stability of the socket joint pipe installation.

[0011] Preferably, the first abutment plate and the second abutment plate are arranged in an arc shape.

[0012] By adopting the above technical solution, and by setting the first abutment plate and the second abutment plate to be arc-shaped, the stability of the first abutment plate abutting against the pipeline and the stability of the second abutment plate abutting against the socket fitting are improved, thereby further improving the stability of the socket joint pipeline installation.

[0013] Preferably, the mounting assembly further includes two rubber pads, which are respectively disposed on the first abutment plate and the second abutment plate.

[0014] By adopting the above technical solution and setting rubber pads, damage to the pipe caused by the first abutment plate and damage to the socket fitting caused by the second abutment plate are minimized. The friction between the first abutment plate and the pipe and between the second abutment plate and the socket fitting is increased to prevent slippage.

[0015] Preferably, the mounting assembly further includes a second pawl and a spring, the second pawl being rotatably connected to the end of the sliding block away from the first pawl, and the spring being disposed between the second pawl and the sliding block to drive the second pawl to abut against the gear.

[0016] By adopting the above technical solution, and by setting a second pawl and a spring, during the rotation of the force-applying rod, the spring drives the second pawl to abut against the gear, so that the two racks can only slide parallel in one direction, thereby improving the stability of the socket interface pipe installation. At the same time, by pressing the second pawl, the abutment limit on the gear is released, so that the racks can slide in the other direction, thereby facilitating the reset of the position between the racks and the sliding block.

[0017] Preferably, the end of the second pawl that is away from the first pawl extends out of the sliding block.

[0018] By adopting the above technical solution, by setting the end of the second pawl away from the first pawl to extend out of the sliding block, it is convenient to press the second pawl, thereby facilitating the release of the second pawl from the contact limit of the gear.

[0019] Preferably, the mounting assembly further includes a gripping head, which is located at the end of the force-applying rod away from the sliding block and is spherically shaped.

[0020] By adopting the above technical solution and setting a gripping head, the force-applying rod can be made to apply force.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By rotating the force-applying rod, the first pawl drives the gear to rotate, which in turn drives the meshing rack to move, so that the socket fitting moves toward the end closer to the pipe, thereby realizing the installation of the socket fitting on the pipe. The operation is simple and convenient, thus facilitating the installation of socket joint pipes.

[0023] 2. By setting a first threading frame and threading a tightening strap through the first threading frame, the pipe is more stably clamped between the two first abutment plates, thereby improving the stability of the socket joint pipe installation;

[0024] 3. By setting a second pawl and a spring, during the rotation of the force-applying rod, the spring drives the second pawl to abut against the gear, so that the two racks can only slide parallel in one direction, thereby improving the stability of the socket joint pipe installation. At the same time, by pressing the second pawl, the abutment limit on the gear is released, so that the rack can slide in the other direction, so that the position between the rack and the sliding block can be reset.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses an installer for socket-type pipes.

[0031] Reference Figure 1 and Figure 2 The installer includes two mounting components 1 and two tightening straps 2. The two mounting components 1 are arranged opposite each other. Specifically, the mounting component 1 includes a sliding seat 11, a connector 12, a force bar 13, a first pawl 14, and a torsion spring 15.

[0032] The sliding seat 11 includes a sliding block 111 and a first abutting plate 112, with the first abutting plate 112 fixedly connected to one side of the sliding block 111. The connecting member 12 includes a rack 121, a gear 122, and a second abutting plate 123. The rack 121 is slidably connected to the sliding block 111 in the direction of its length. The gear 122 is rotatably connected to the sliding block 111 and meshes with the rack 121. The second abutting plate 123 is fixedly connected to the side of the rack 121 near the first abutting plate 112.

[0033] The lower end of the force-applying rod 13 is rotatably connected to both sides of the sliding block 111. The first pawl 14 is rotatably connected to the lower end of the force-applying rod 13. The torsion spring 15 is installed between the first pawl 14 and the force-applying rod 13 to drive the first pawl 14 to rotate so that the first pawl 14 abuts against the limiting gear 122.

[0034] In this embodiment, the tightening band 2 is a binding band ratchet tensioner. Two tightening bands 2 are spaced apart along the length of the rack 121. One tightening band 2 is connected to two sliding blocks 111, and the other tightening band 2 is connected to two racks 121. By operating the tightening band 2, tightening can be achieved between the two sliding blocks 111 or between the two racks 121. The binding band ratchet tensioner is existing technology, and its specific structure will not be described.

[0035] In practical applications, the socket fitting 32 is first pre-installed on one end of the pipe 31. Two installation components 1 are located on both sides of the pipe 31 and the socket fitting 32, so that the two first abutment plates 112 abut against the periphery of the pipe 31 and the two second abutment plates 123 abut against the periphery of the socket fitting 32. One tightening band 2 tightens and fixes the two sliding blocks 111, so that the pipe 31 is clamped to the two first abutment plates 112. The other tightening band 2 tightens and fixes the two racks 121, so that the socket fitting 32 is clamped to the two second abutment plates 123.

[0036] Among them, because the torsion spring 15 drives the first pawl 14 to abut against the gear 122, towards Figure 2 Rotate the force bar 13 counterclockwise so that the first pawl 14 drives the gear 122 to rotate counterclockwise, thereby driving the meshing rack 121 to move toward one end of the pipe 31, so that the socket fitting 32 moves toward the end closer to the pipe 31, so that the socket fitting 32 is close to the pipe 31, thereby realizing the installation of the socket fitting 32 on the pipe 31. The operation is simple and convenient, thus facilitating the installation of the socket interface pipe 3.

[0037] Reference Figure 2 In some embodiments, the sliding seat 11 further includes a first wire-passing frame 113, which is fixedly connected between the sliding block 111 and the first abutment plate 112 for the tightening strap 2 to pass through. By passing the tightening strap 2 through the first wire-passing frame 113, the pipe 31 is more stably clamped between the two first abutment plates 112, thereby improving the stability of the socket interface pipe 3 installation.

[0038] In some embodiments, the connector 12 further includes a second threading frame 124, which is fixedly connected between the rack 121 and the second abutment plate 123 for the tightening strap 2 to pass through. By passing the tightening strap 2 through the second threading frame 124, the socket fitting 32 is more stably clamped between the two second abutment plates 123, thereby improving the stability of the socket interface pipe 3 installation.

[0039] In some embodiments, the first abutment plate 112 is arranged in an arc shape so that the first abutment plate 112 fits against the periphery of the pipe 31 to improve the stability of the first abutment plate 112 against the pipe 31. The second abutment plate 123 is also arranged in an arc shape so that the second abutment plate 123 fits against the periphery of the socket fitting 32 to improve the stability of the second abutment plate 123 against the socket fitting 32, thereby further improving the stability of the socket joint pipe 3 installation.

[0040] In some embodiments, the mounting assembly 1 further includes two rubber pads 16, which are respectively fixedly connected to the side of the first abutment plate 112 away from the sliding block 111 and the side of the second abutment plate 123 away from the rack 121. This can minimize the damage caused by the first abutment plate 112 abutting against the pipe 31 and minimize the damage caused by the second abutment plate 123 abutting against the socket fitting 32. It also increases the friction between the first abutment plate 112 and the pipe 31 and the second abutment plate 123 and the socket fitting 32 to prevent slippage.

[0041] Reference Figure 2 and Figure 3 In some embodiments, the mounting assembly 1 further includes a second pawl 17 and a spring 18. The second pawl 17 is rotatably connected to the end of the sliding block 111 away from the first pawl 14. One end of the spring 18 elastically abuts against the end of the second pawl 17 away from the first pawl 14, and the other end elastically abuts against the sliding block 111 to drive the second pawl 17 to rotate so that the second pawl 17 abuts against the gear 122.

[0042] During the rotation of the force-applying rod 13, the spring 18 drives the second pawl 17 to abut against the gear 122, so that the two racks 121 can only slide in parallel in one direction, thereby improving the stability of the socket interface pipe 3 installation. At the same time, by pressing the second pawl 17, the abutment limit on the gear 122 is released, thereby facilitating the sliding of the rack 121 in the other direction, so as to reset the position between the rack 121 and the sliding block 111.

[0043] In some embodiments, the end of the second pawl 17 away from the first pawl 14 extends out of the sliding block 111 to facilitate pressing the second pawl 17, thereby facilitating the release of the second pawl 17 from the contact limit of the gear 122.

[0044] In some embodiments, the mounting assembly 1 further includes a gripping head 19, which is fixedly connected to the upper end of the force-applying rod 13 and is spherically shaped to facilitate the force-applying rod 13 in applying force.

[0045] The implementation principle of this embodiment is as follows: In practical application, the socket fitting 32 is first pre-installed on one end of the pipe 31. Two installation components 1 are located on both sides of the pipe 31 and the socket fitting 32, so that the two first abutting plates 112 abut against the periphery of the pipe 31 and the two second abutting plates 123 abut against the periphery of the socket fitting 32. One tightening band 2 tightens and fixes the two sliding blocks 111, so that the pipe 31 is clamped to the two first abutting plates 112. The other tightening band 2 tightens and fixes the two racks 121, so that the socket fitting 32 is clamped to the two second abutting plates 123.

[0046] Among them, because the torsion spring 15 drives the first pawl 14 to abut against the gear 122, towards Figure 1 Rotate the force bar 13 counterclockwise so that the first pawl 14 drives the gear 122 to rotate counterclockwise, thereby driving the meshing rack 121 to move toward one end of the pipe 31, so that the socket fitting 32 moves toward the end closer to the pipe 31, so that the socket fitting 32 is close to the pipe 31, thereby realizing the installation of the socket fitting 32 on the pipe 31. The operation is simple and convenient, thus facilitating the installation of the socket interface pipe 3.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
