Abstract
The utility model discloses a connecting device of compound pipe fittings, which is composed of a fastening nut (1) and a column tube (2), wherein, the left section of the internal diameter of the fastening nut (1) is provided with pitch; a left port of the column tube (2) is symmetrically provided with two V-shaped openings for contracting towards right. The device has the characteristics of simple structure, low cost, convenient installation, good sealing performance, etc., and is an ideal connecting device of compound tap water pipe fittings.
Description
The utility model relates to the connection fittings that a kind of composite pipe is used, particularly a kind of composite pipe connection set of accessory.
Current, composite running water pipe has begun to apply at home, but the amplitude of promoting is little, and its main cause is an accessory cost height, mostly adopts the copper material of doing, complex structure, and manufacturing procedure is many, the expense height, and exist the pollution problem of secondary copper.In recent years, some producers replaced copper with the import plastics, develop overall plastic accessory, but be complex structure after all, processing charges is many, cost is high, install, overhaul inconvenience etc.
The purpose of this utility model provides a kind of simple in structure, low, the simple installation of cost, the composite pipe of the good airproof performance connection set of accessory.
The purpose of this utility model is achieved like this:
Include column jecket (2), the external cylindrical surface of column jecket (2) has screw thread (4), and its post jamb is turned right from left port, has " V " shape mouth of two symmetries; On column jecket (2), also be with tightening nut (1).
The screw thread that tightening nut (1) and column jecket (2) match is a pipe thread, and the internal diameter of tightening nut (1) internal thread is divided into two sections, and its right section (5) is normal pipe thread internal diameter, and left side section (6) has gradient.
The draft angle of tightening nut (1) minor diameter of internal thread left side section (6) is 1～3.5 °.
The screw thread that tightening nut (1) and column jecket (2) match is a taper pipe thread.
The composite pipe of the present utility model connection set of accessory, owing to only constitute by tightening nut and column jecket, so simple in structure, and can be once injection molded, thereby cost is low.Simultaneously, when mounted, after only some plastic bonding glue need being coated in the end of composite pipe, directly insert in the column jecket endoporus, screw tightening nut, force the position of column jecket left end band " V " shape opening to produce by the gradient of tightening nut minor diameter of internal thread left side section and shrink and the composite pipe of holding with a firm grip, in addition, because the ramp effect of tightening nut internal diameter can produce bigger self-lock force.Thereby its installation is easier, be connected firmly, and sealing is better.
Accompanying drawing 1 is a main sectional view of the present utility model;
Accompanying drawing 2 is left views of the present utility model;
Accompanying drawing 3 is main sectional views of tightening nut of the present utility model.
Below in conjunction with accompanying drawing, describe two embodiments of the present utility model in detail.
Embodiment one:
Present embodiment is to be made of tightening nut (1), column jecket (2) and accessory joint (7).
The profile of tightening nut (1) is a hexagon, and internal thread is a pipe thread, and its left side section internal diameter (6) has gradient, and right section internal diameter (5) is normal pipe thread internal diameter.
Column jecket (2) is the sleeve of a tyre pipe thread, and its left port has " V " shape opening of two contraction usefulness to the right symmetrically.
Accessory joint (7) comprises the outer tooth straight joint of hexagonal fastening position and right-hand member.
The left end of the right-hand member of column jecket (2) and accessory joint (7) is connected as a single entity, and forms an endoporus seam in the joint.
Corresponding relation between the draft angle of the internal diameter left side section (6) of tightening nut (1) and composite pipe (8) the inside/outside footpath is:
φ12/φ16-1～2° φ14/φ18-2.5～3°
φ16/φ20-3～3.5° φ20/φ25-3～3.5°
During installation, tightening nut (1) is inserted on the composite pipe (8), coat plastic bonding glue in the right part of composite pipe (8) again, to manage (8) and directly insert the endoporus of column jecket (2) to endoporus seam position, pipe (8) is stationary fit with the endoporus of column jecket (2), again with tightening nut (1) precession column jecket (2), at this moment, the gradient of tightening nut (1) minor diameter of internal thread left side section, the left side section that forces column jecket (2) to have " V " shape opening produces shrinks, and hangs on to composite pipe (8), in addition the internal diameter gradient of tightening nut (1), bigger self-lock force be can produce, thereby firm connection and better seal formed.Thereafter, the right-hand member of accessory joint (7) being loaded onto other accessories can use.
Embodiment two:
Present embodiment also is to be made of tightening nut (1) and column jecket (2) and accessory joint (7).
The profile of tightening nut (1) is a hexagon, and internal thread is a taper pipe thread.
Column jecket (2) is the sleeve of a tyre taper pipe thread, and its left port has " V " shape opening of two contraction usefulness to the right symmetrically.
Accessory joint (7) comprises the outer tooth straight joint of hexagonal fastening position and right-hand member.
The left end of the right-hand member of column jecket (2) and accessory joint (7) is connected as a single entity, and forms an endoporus seam in the joint.
It installs and uses identical with embodiment one.
The accessory joint (7) that fuses with the utility model both can be outer tooth straight joint, also can be interior tooth joint, can also be the connection set identical with the utility model.
The utility model links to each other with the accessory joint of other types, can also form elbow, threeway, even accessory such as four-way.
