[0002] In some pipeline connection hardware is connected, for example, water heating pipe fitting: for example, the joint of water pipe, including elbow, tee, direct head and the like hardware, assemble round rubber ring at the connecting place of these pipe fittings, can play the role of sealing, prevent water leakage. Because water heating system is usually operated under pressure, round rubber ring can fill the small gap between pipe fittings, ensure the sealing of pipeline system. Like the water pipe connection of household kitchen and bathroom, widely use this pipe fitting with round rubber ring, or gas pipeline fitting: for the pipeline hardware that transports natural gas or liquefied gas, safety is crucial. Round rubber ring is installed at pipe fitting connecting part, can effectively prevent gas leakage. These round rubber rings usually need to have good corrosion resistance and aging resistance to adapt to the chemical properties of gas and long-term use environment.

[0003] But in actual use process, some round rubber rings need to be closely fitted to prevent round rubber ring loosening when assembling, usually ring-shaped clamping groove is set on the surface of pipeline to install, to ensure that round rubber ring can keep the state of close fitting after installation, and displacement does not occur, so that the outer diameter of round rubber ring is usually less than that of pipeline, so that workers need to expand round rubber ring to make the inner diameter of round rubber ring greater than the outer diameter of pipeline to set, but this greatly increases the difficulty of operation, and is more laborious. In view of this, we propose a kind of round rubber ring hardware assembly feeding mechanism. UTILITY MODEL CONTENTS

[0023] 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.

[0024] A feeding mechanism for assembling round rubber ring hardware parts, such as Figure 1 - Figure 4As shown, the device includes a first circular tube 1, an internal feeding mechanism 2, and an installation mechanism 3 at the bottom of the first circular tube 1. The feeding mechanism 2 includes a pressure rod 21, which is slidably connected to the inner wall of the first circular tube 1. A lever 22 is fixedly connected to the bottom of the pressure rod 21. Connecting rings 23 are fixedly connected to the first circular tube 1 above and below the lever 22, respectively. Piston cylinders 24 are fixedly connected to the top and bottom of the lever 22, respectively, and the piston cylinders 24 are connected to the corresponding connecting rings 23. The inner wall is fixedly connected, and the inside of the connecting ring 23 is provided with an annular air chamber 25. The inside of the annular air chamber 25 is connected to the piston cylinder 24 at the corresponding position through the air pipe 241. The inner wall of the annular air chamber 25 is slidably connected with a locking block 26, and the locking block 26 can extend out of the connecting ring 23. There are three sets of piston cylinders 24 and locking blocks 26 on the connecting ring 23, and they are arranged in an annular array. The bottom of the pressure rod 21 is fixedly connected to the position between the bottom of the pressure rod 21 and the inner wall of the first circular tube 1, which is used to reset the pressure rod 21.

[0025] In this embodiment, the circular rubber ring to be installed is fitted onto the outer wall of the first circular tube 1. Each time installation is performed, simply press the lever 21 with your finger. The lever 21 causes the paddle 22 to sink, so that the piston cylinder 24 above the paddle 22 draws air from the upper annular air chamber 25 through the air pipe 241, causing the upper locking block 26 to retract into the upper annular air chamber 25. At the same time, the air inside the piston cylinder 24 below the paddle 22 is squeezed into the lower annular air chamber 25 through the air pipe 241, causing the lower locking block 26 to extend. This causes the circular rubber ring above the upper locking block 26 to fall between the upper and lower locking blocks 26. Then, releasing the tension of the first spring 27 pushes the lever 21 back to its original position, causing the paddle 22 to rise, causing the lower locking block 26 to retract and the upper locking block 26 to extend. This alternating extension and retraction ensures that each press and release of the lever 21 replenishes a circular rubber ring to the position of the installation mechanism 3, facilitating installation and improving installation efficiency.

An installation rod 34 is hinged to the bottom of the outer wall of the second circular tube 31. A traction rod 35 is hinged to the top of the outer wall of the top rod 33, and the top of the traction rod 35 is hinged to the corresponding installation rod 34. There are three traction rods 35 and three installation rods 34, which are arranged in a circular array.

[0027] In this embodiment, each time the installation is carried out, the top rod 33 is pressed against one end of the pipeline to be installed, the second circular tube 31 is pushed so that the top rod 33 is retracted into the inside of the second circular tube 31, due to the connection relationship between the installation rod 34 and the traction rod 35, the traction rod 35 drives the top of the installation rod 34 to expand outward, so that the three installation rods 34 change from the state of being small at the top and large at the bottom to being large at the top and small at the bottom, so that the rubber ring is expanded and is extruded to be sleeved on the outer wall of the pipeline to facilitate installation, thereby greatly reducing the difficulty of installation.

[0028] As shown in Figure 4 Preferably, the top of the top rod 33 is fixedly connected with the second spring 36 between the inner wall of the second circular tube 31, and the second spring 36 is sleeved on the outside of the inner rod 32.

[0029] In this embodiment, the top rod 33 is reset when the second circular tube 31 is relaxed each time the installation of the rubber ring is completed, through the tension of the second spring 36.

[0030] The utility model discloses a kind of rubber ring hardware assembly feeding mechanisms, when using, the rubber ring to be installed is sleeved on the outer wall of the first circular tube 1, each time the installation is carried out, only need to press down the pressure bar 21 by finger, the piston cylinder 24 above the paddle 22 is extracted air in the annular air chamber 25 above by air pipe 241, so that the upper clamping block 26 is retracted into the annular air chamber 25 above, while the air in the piston cylinder 24 below the paddle 22 is extruded into the annular air chamber 25 below by air pipe 241, so that the lower clamping block 26 is extended, so that the rubber ring above the upper clamping block 26 falls to the position between the upper and lower clamping block 26, then release finger, the tension of the first spring 27 pushes the pressure bar 21 to reset so that the paddle 22 is raised, so that the lower clamping block 26 is retracted, the upper clamping block 26 is extended, to this alternately expansion and contraction, so that each press and release pressure bar 21 will supplement a rubber ring to the position of installation mechanism 3, to facilitate installation, thereby improve the efficiency of installation, each time the installation is carried out, the top rod 33 is pressed against one end of the pipeline to be installed, the second circular tube 31 is pushed so that the top rod 33 is retracted into the inside of the second circular tube 31, due to the connection relationship between the installation rod 34 and the traction rod 35, the traction rod 35 drives the top of the installation rod 34 to expand outward, so that the three installation rods 34 change from the state of being small at the top and large at the bottom to being large at the top and small at the bottom, so that the rubber ring is expanded and is extruded to be sleeved on the outer wall of the pipeline to facilitate installation, thereby greatly reducing the difficulty of installation, and the top rod 33 is reset when the second circular tube 31 is relaxed each time the installation of the rubber ring is completed, through the tension of the second spring 36.
