Structural improvement of pipe joints

The structure of the pipe joint is improved, and the inner edge hole surface of the inner hole of the joint body of the pipe joint is mainly arranged to have a locking hole surface shape for inserting, and the joint body densely connected with the conveying pipe is arranged. It can be easily disassembled and locked by the other side of the assembled manifold, which achieves the practical operation purpose of simple and independent assembly and disassembly of the shunting pipe joint.

Generally, the transportation of the air pressure or hydraulic pipeline usually needs to be connected by a large number of conveying pipe members for conveying the pressurized air or fluid to the driving operation position using the machine tool, thereby achieving the operation operation of the control tool device; The conveying pipe is respectively connected to one end of the operating machine and the pressurized storage tank, that is, the pressure input end is locked to a predetermined charging air or oil fluid storage tank output end, generally after the fluid inside the tank body is pressurized, The output end of the trough body locks a shunt plate, and the pipe joints pivotally connected at one end of each conveying pipe member are arranged in a centralized arrangement and locked on a preset output port of the diverter plate, and the conventional pipe joint design is usually only The outer ring of the pipe joint pre-sets the pivoting bolt head for convenient locking to the preset pivoting screw hole on the diverter plate to communicate with the oil or gas fluid storage tank, so as to convey the pressure after pressurization The machine to be operated is used as a control for processing or actuation.

According to the above-mentioned traditional conveying pressure pipe fitting and assembly connection structure design, since the same pressurized storage tank can be used as a power source for multiple sets of related pressure control, all the conveying pipes are concentratedly locked at the same output shunt. On the board, in order to achieve the stability of the actual output pressure and the convenience of assembly, there is usually a certain proportion of the amplitude and the volume limitation and calculation of the appropriate output flow, usually as shown in the fifth figure, that is, the joint body of the pipe joint (30) Inserting the locking tube (31) After one end, the tool is locked to the diverter plate (32) one by one to form a very dense arrangement, and the extended conveying pipe (31) will be intertwined according to different machines or positions connected. Irregular extension, when the connection is assembled, the screw holes (33) preset by the splitter plate (32) are sequentially arranged and locked one by one, and there is not much technical difficulty, but when used, a single one is used. When the conveying pipe (31) is damaged or the position of the connecting pipe is lost, it is almost impossible to remove any single pipe fitting due to the dense arrangement, and unless it is just arranged at the most side position, the replacement operation cannot be performed at all. The whole splitter plate (32) needs to be disassembled, and then disassembled from the outside to the inside of the damaged joint body (30) one by one, and then removed, before the new repair operation can be performed, and then one by one. The removed joint body (30) and the pipe fittings are locked back, otherwise the relative repair operation cannot be performed. Therefore, in many cases, the outer end of the joint body (30) is directly closed, that is, Dismantle the use of the pipeline, but this will form the actual implement control Inconvenience, the locking structure of the joint body (30) on the current high-pressure conveying and diverting device is designed in such a manner that it is designed to be repaired and refitted, and the arrangement density is directly increased. However, the redundant waste of the actual pressurizing device is formed. How to redesign the current joint body (30) lock design, and to meet the convenience of the actual use of assembly and repair, in fact, further research and improvement are needed. Design space.

The creator has many years of experience in oil pressure assembly design, and is extremely aware of the lack of inconvenience in the assembly and maintenance of the general pressure transmission assembly. It has been based on the actual development and design experience and production assembly experience. The use of the assembly convenience requires an improved design, and finally the structural improvement of the original pipe joint is developed, and is directly formed on the hole surface of the joint body on the side of the inner hole of the joint body. The locking hole surface of the card is inserted and operated by the tool insert at the other end of the pipe joint, thereby effectively improving the inconvenience of the current assembly and disassembly.

The purpose of the creation of the creation is: according to the end edge of the inner hole of the joint body, the one-side or the polygonal locking hole surface with the plug-in is provided for the simple replacement of the other side of the assembled manifold The lock is assembled and assembled, which facilitates the use of the separate and independent decoration and protection operation of the split flow output pipe.

In order to facilitate your review committee to further understand the structural features of this creation and its practical purposes, the following is a detailed description of the following examples:

The structure of the pipe joint is improved, and the entire structure is improved. As shown in the first to fourth figures, the structural appearance of the entire joint body (10) is roughly different from the current common outer vicinity, that is, the joint body (10) is roughly divided into two. The half and half of the thinner diameter are set to the threaded section (11) with the external thread locking design, and the other side is set to the polygonal bolt head (12) for the outer side locking, and the central through hole (13), the hole diameter on one side of the bolt head (12) is slightly larger, and the inner hole edge surface on the other side is extended inward by the other end of the joint body (10) by an appropriate length. The locking hole surface (14) of the engaging side surface design can be a single-sided or polygonal inner hole edge, which can be directly formed according to the size of the general locking tool (20) such as a hex wrench, and is formed into a relative polygon. The edge of the hole is convenient and easy to use for locking operation; and the larger inner hole part of the bolt head (12) is just for the end of the pipe end of a conveying pipe (15) to be locked or welded and assembled to complete the composition. The conveying pipe structure, and the entire joint body (10) is directly locked to the splitter plate (21) assembled at the output end of the pressurized storage tank, The divided surface arranged combination lock screw (22), so that the same manifold (21) may be provided using a pressure control unit coupled myriad; and present writing (10) the central flow bore (1 in the joint body 3) The locking hole surface (14) provided on one side can provide the other side of the independent single conveying pipe that can be damaged or leaked. The other side can be locked by the diverter plate (21), and the damage is directly leaked by the tool (20). The pipe fittings and the disassembling operation of the joint body (10) do not affect the other pipe fittings adjacent to each other, and the simple operation of the damage or repair and replacement is achieved, so that the maintenance and disassembly assembly of the entire pressurized pipeline supply system is achieved. The purpose of quick and easy operation is practical.

The structural improvement of the entire joint body (10) of the present invention is that the hole edge surface of the inner hole (13) flows through one end of the joint body (10), and is designed to have a locking hole surface (14) with a snap-in side surface. When the pipe joints are arranged one by one, the pipe structure is properly arranged, and when some damage or breakage occurs, the single pipe member can be removed by the broken pipe (21), and the other is locked by the plate surface. On the side, the damaged pipe fittings are directly disassembled by the locking tool (20), so that the card inserted through the locking hole surface (14) of the joint body (10) can be easily assembled and replaced. The whole operation will not affect the assembly safety of other pipe fittings around, and because of the flatness of the other side of the manifold (21), it can receive the convenient and quick practical effect of the assembly and disassembly operation. The improved design of the inner hole of the joint body (10) of the joint not only has the innovation of structural design, but also meets the elastic use requirement of rapid and disassembling assembly.
