Description

Technical Field

[0001] The utility model relates to the technical field of pipeline accessories, in particular to a pipeline accessory which is easy to install. Background Art

[0002] Pipe fittings are devices or components used in piping systems to connect, control, regulate, divert, support, or protect pipelines. They play a vital role in pipeline transportation systems, ensuring that fluids can be transported efficiently and safely from one location to another. The following are some common pipe fittings and their functions: Connectors: used to connect two or more pipes to ensure that fluids can flow smoothly between the pipes; Valves: used to control the flow of fluids, such as opening, closing, and regulating flow or pressure; Filters: used to filter impurities in the fluid to protect the pipeline system and downstream equipment from damage; Flanges: used to connect pipes and equipment; Compensators: used to absorb the displacement and stress of the pipeline caused by temperature changes, pressure fluctuations, or installation errors, protecting the pipeline system from damage; Brackets and hangers: used to support and fix the pipeline system to ensure that the pipeline remains stable when transporting fluids; Tees and Crosses: used to divert fluids from one pipe to two or three pipes, or to merge fluids from multiple pipes into one pipe; Quick Connectors: used in pipeline systems that require frequent connection and disconnection, such as hydraulic equipment, pneumatic tools, and test equipment. Quick connectors are easy to operate, have reliable connections, and offer excellent sealing performance. Pipeline accessories, such as thermometers, pressure gauges, and flow meters, are used to monitor and control fluid parameters in the piping system to ensure safe and efficient operation of the system.

[0003] Chinese patent publication number CN208735075U discloses an internal heating pipe fitting, comprising a connecting pipe, a docking ring fixedly connected at the midpoint of the upper and lower inner walls of the connecting pipe, docking grooves provided at the left and right end ports of the docking ring, a rubber sleeve fixedly connected around the inner edge of the docking groove, iron blocks fixedly attached to the upper and lower ends of the inner wall of the rubber sleeve, and threaded push rods vertically provided on the side walls of the connecting pipe facing the upper and lower sides of the rubber sleeve, and the threaded push rods extend to the outside of the connecting pipe. The rubber sleeve of the utility model expands when heated, pushing outward against the curved pressure plate and the threaded push rod. A gap is reserved between the threaded connection block and the movable groove to facilitate the threaded push rod to move and tighten against the block, thereby enhancing the tightness of the connection between the pipe fitting and the connecting pipe, while preventing the threads of the threaded push rod from being brittle due to temperature changes and the force of thermal expansion. In addition, the asbestos fixedly attached to the outer end of the rubber sleeve is used to reduce the heat transferred from the end of the internal heating pipe to the connecting pipe.

[0004] The above-mentioned existing technical solutions have the following defects: most of the existing pipes are connected by threads, and threaded connections mainly rely on the engagement of threads to achieve pipe connection. The connection strength is relatively low. When subjected to large pressure, tension or impact force, the threaded connection parts may become loose, leak, and other problems, affecting the normal operation of the pipeline system. At the same time, when tightening the screws, if too much force or too much deviation is used, the thread teeth may be subjected to excessive pressure and wear, and then thread slippage may occur. As the use time increases, the thread teeth in the threaded connection may gradually wear due to frequent friction and force, eventually leading to thread slippage. Therefore, we propose a pipe fitting that is easy to install to solve the problems raised above. Utility Model Content

[0005] The purpose of the present utility model is to provide a pipe fitting that is easy to install, so as to solve the problem proposed in the above background technology that most of the existing pipes are connected by threads, and the threaded connection mainly relies on the engagement of the threads to achieve the connection of the pipes. The connection strength is relatively low. When subjected to large pressure, tension or impact force, the threaded connection parts may become loose, leak or have other problems, affecting the normal operation of the pipeline system. At the same time, when tightening the screws, if too much force or too much deviation is used, the threads may be subjected to excessive pressure and wear, and then the thread slippage phenomenon may occur. As the use time increases, the threads in the threaded connection may gradually wear due to frequent friction and force, eventually leading to the problem of thread slippage.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pipe fitting that is easy to install, comprising a pipe, an outer sleeve at the two pipe connection positions is provided with a pipe connecting sleeve, eight positioning blocks are provided in an outer ring at both ends of the pipe, and eight positioning block grooves are provided in an inner ring at both ends of the pipe connecting sleeve, and the positioning block grooves are provided corresponding to the positioning blocks, a first locking strip groove is provided on one side of the positioning block groove, a second locking strip groove is provided inside the positioning block, a locking strip is provided inside the positioning block groove for sliding, and one end of the locking strip extends to the inside of the second locking strip groove.

[0007] Preferably, a compression spring groove is provided on the outside of the first locking strip groove, and a compression spring is provided on the inside of the compression spring groove.

[0008] Preferably, a limiting ring is provided on the outside of the middle position of the locking strip, one end of the compression spring is fitted with the inner wall of the compression spring groove, and the other end of the compression spring is fitted with the limiting ring.

[0009] Preferably, a magnet block is provided inside one end of the locking bar, and an electromagnet is installed on one side of the positioning block groove, and the electromagnet is provided corresponding to the magnet block.

[0010] Preferably, a filter screen fixing frame is fixedly installed at a middle position inside the pipe connecting sleeve, two sides of the filter screen fixing frame are sealedly connected to the pipe, and a filter screen is fixedly arranged inside the filter screen fixing frame.

[0011] Preferably, six sealing gaskets are symmetrically installed on both sides of the filter screen fixing frame, and the sealing gaskets fit the pipeline.

[0012] Preferably, the positioning block groove is an L-shaped groove, the upper end of the positioning block groove is vertically arranged, and the lower end of the positioning block groove is horizontally arranged.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. When the utility model connects the pipe and the pipe connecting sleeve, the electromagnet is turned on. After the electromagnet is turned on, a magnetic field is generated. The magnetic field of the electromagnet repels the magnetic field of the magnet block. When the repulsive force is greater than the elastic force of the compression spring, the magnetic force shrinks the locking bar provided with the electromagnet toward the inside of the first locking bar groove, and the positioning block of the pipe is aligned with the positioning block groove. The positioning block is pushed into the vertical groove of the positioning block groove. When it moves to the bottom of the vertical groove, it rotates along the horizontal groove to move to the inside of the horizontal groove. When it moves to the second locking bar groove and corresponds to the locking bar, the power supply of the electromagnet is disconnected, the magnetic force of the electromagnet disappears, and the elastic force of the compression spring pushes the locking bar into the second locking bar groove of the locking bar, thereby locking the position of the locking bar. It is fixed, thereby preventing the rotation of the pipeline, thereby avoiding the loosening of the horizontal position, vertical position and rotation angle of the pipeline, and solving the problem that most existing pipelines are connected by threads. Threaded connections mainly rely on the engagement of threads to achieve pipe connection, and their connection strength is relatively low. When subjected to large pressure, tension or impact force, the threaded connection parts may become loose, leak, and other problems, affecting the normal operation of the pipeline system. At the same time, when tightening the screws, if too much force or too much deviation is used, the thread teeth may be subjected to excessive pressure and wear, and then slippage may occur. As the use time increases, the thread teeth in the threaded connector may gradually wear due to frequent friction and force, eventually leading to the problem of slippage.

[0015] 2. Six sealing gaskets are respectively provided on both sides of the connection between the two pipes of the utility model. The sealing gaskets can effectively improve the sealing between the pipe and the pipe connecting sleeve and the two pipes. The filter screen can filter the medium flowing between the two pipes. The filter screen can effectively intercept and remove impurities in the fluid flowing in the pipe, such as particulate matter, fiber, debris, etc. If these impurities are not removed, they may damage downstream pumps, valves, nozzles, instruments and other key equipment, causing leakage, blockage or failure. Through the protection of the filter screen, the normal operation of downstream equipment can be ensured, and the maintenance and replacement costs can be reduced. The filter screen can maintain the cleanliness of the fluid in the pipe, thereby improving the flow and pressure stability of the system. By regularly replacing or cleaning the filter screen, potential problems can be discovered and solved in time to avoid more serious failures. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figure 1-4The utility model provides an embodiment: a pipe fitting that is easy to install, including a pipe 1, a pipe connecting sleeve 2 is provided on the outer sleeve at the connection position of the two pipes 1, eight positioning blocks 3 are provided on the outer ring at both ends of the pipe 1, and eight positioning block grooves 10 are provided on the inner ring at both ends of the pipe connecting sleeve 2, and the positioning block grooves 10 are provided corresponding to the positioning blocks 3, a first locking strip groove 6 is provided on one side of the positioning block groove 10, a second locking strip groove 11 is provided inside the positioning block 3, a locking strip 4 is provided inside the positioning block groove 10 for sliding, and one end of the locking strip 4 extends to the inside of the second locking strip groove 11.

[0023] When the pipe 1 and the pipe connecting sleeve 2 are connected, the electromagnet 13 is turned on. When the electromagnet 13 is turned on, a magnetic field is generated. The magnetic field of the electromagnet 13 repels the magnetic field of the magnet block 12. When the repulsive force is greater than the elastic force of the compression spring 8, the magnetic force will cause the locking bar 4 provided with the electromagnet 13 to contract toward the inside of the first locking bar groove 6, and the positioning block 3 of the pipe will correspond to the positioning block groove 10, and the positioning block 3 will be pushed into the vertical groove of the positioning block groove 10. When it moves to the bottom of the vertical groove, it rotates along the horizontal groove and moves to the inside of the horizontal groove. When it moves to the second locking bar groove 11 and corresponds to the locking bar 4, the power supply of the electromagnet 13 is disconnected, the magnetic force of the electromagnet 13 disappears, and the elastic force of the compression spring 8 pushes the locking bar 4 into the second locking bar groove 11 of the locking bar 4, thereby locking the position of the locking bar 4, thereby preventing the pipe 1 from rotating, thereby preventing the horizontal position, vertical position and rotation angle of the pipe 1 from loosening.

[0024] See also Figure 1-2 A compression spring groove 7 is provided on the outside of the first locking strip groove 6, a compression spring 8 is provided inside the compression spring groove 7, and a limiting ring 9 is provided on the outside of the middle position of the locking strip 4. One end of the compression spring 8 is in contact with the inner wall of the compression spring groove 7, and the other end of the compression spring 8 is in contact with the limiting ring 9.

[0025] See also Figure 1-2 A magnet block 12 is provided inside one end of the locking bar 4 , and an electromagnet 13 is installed on one side of the positioning block groove 10 , and the electromagnet 13 is provided corresponding to the magnet block 12 .

[0026] See also Figure 1 and Figure 3 A filter screen fixing frame 14 is fixedly installed at the middle position inside the pipe connecting sleeve 2. Both sides of the filter screen fixing frame 14 are sealed with the pipe 1. A filter screen 5 is fixed inside the filter screen fixing frame 14. Six sealing gaskets 15 are symmetrically installed on both sides of the filter screen fixing frame 14, and the sealing gaskets 15 fit the pipe 1.

[0027] See also Figure 4The positioning block groove 10 is an L-shaped groove, the upper end of the positioning block groove 10 is vertically arranged, and the lower end of the positioning block groove 10 is horizontally arranged.

[0028] Working principle: When connecting the pipe 1 and the pipe connecting sleeve 2, turn on the electromagnet 13. After the electromagnet 13 is turned on, a magnetic field is generated. The magnetic field of the electromagnet 13 repels the magnetic field of the magnet block 12. When the repulsive force is greater than the elastic force of the compression spring 8, the magnetic force will cause the locking bar 4 provided with the electromagnet 13 to shrink toward the inside of the first locking bar groove 6, and the positioning block 3 of the pipe will correspond to the positioning block groove 10. The positioning block 3 is pushed into the vertical groove of the positioning block groove 10. When it moves to the bottom of the vertical groove, it rotates along the horizontal groove and moves to the inside of the horizontal groove. When it moves to the second locking bar groove 11 and corresponds to the locking bar 4, the power supply of the electromagnet 13 is disconnected, the magnetic force of the electromagnet 13 disappears, and the elastic force of the compression spring 8 pushes the locking bar 4 into The second locking groove 11 of the locking bar 4 locks the locking bar 4 in place, preventing the pipe 1 from rotating and thus preventing loosening of the horizontal and vertical positions and angles of rotation. Six sealing gaskets 15 are provided on either side of the connection between the two pipes 1. These gaskets 15 effectively improve the sealing between the pipe 1 and the pipe connector 2, as well as between the two pipes 1. The filter 5 filters the medium flowing between the two pipes, effectively intercepting and removing impurities such as particulate matter, fibers, and debris from the fluid flowing through the pipes. If these impurities are not removed, they can damage downstream critical equipment such as pumps, valves, nozzles, and instruments, leading to leaks, blockages, or failures. The protection provided by the filter 5 ensures the normal operation of downstream equipment and reduces maintenance and replacement costs. The filter 5 maintains the cleanliness of the fluid within the pipe, thereby improving the flow and pressure stability of the system. By regularly replacing or cleaning the filter 5, potential problems can be discovered and resolved promptly, preventing more serious failures.
