Abstract
The utility model belongs to the technical field of air conditioning refrigeration systems, particularly relates to a novel connector, and is used for solving the problems that the existing connector is inconvenient to install and small in range of application and the like. The novel connector comprises a connector nut, wherein a first cylindrical body and a second cylindrical body are respectively arranged at two ends of the connector nut, the first cylindrical body is provided with first outer threads, the second cylindrical body is provided with second outer threads, the outer diameter of the first cylindrical body is gradually reduced from the end connected with the connector nut to the other end, and the outer diameter of the end, connected with the connector nut, of the first cylindrical body is equal to the outer diameter of the second cylindrical body. The novel connector has the advantages of being simple and reasonable in structure and more convenient to install due to the end with smaller outer diameter of the first cylindrical body and a guide head on the second cylindrical body, greatly improving the installation efficiency, having better airtightness, and being not easy to leak, wide in range of application, high in strength, low in cost and long in service life.
Description
Technical field
The utility model belongs to the air-conditioning refrigeration system technical field, especially relates to a kind of Novel joint.
Background technique
Along with the raising day by day of people's living standard, air-conditioning refrigeration system is increasingly mature.At the air-conditioning refrigeration system middle joint, it is a kind of important accessory; it be mainly used between tube and tube or pipe and equipment between be connected; in order to guarantee gas or liquid state in body, do not leak; joint must have sealing preferably, thereby but existing joint often can the phenomenon of leaking closely not occur owing to connecting when mounted.Except outside existing joint also exist: complex structure, inconvenience is installed, the problem such as Applicable scope is little, and intensity is low, and cost is higher.
The problem existed in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of pipe coupling [application number: 97212352.0], and it is threaded onto the Female connector fittings of pipe coupling by outside thread pipeline joint, and the plastic seal collar in joint forms.Such scheme has solved the high problem of existing joint cost to a certain extent, but because plastic clamp ring intensity is lower, fragile, except outside this scheme still exist: inconvenience is installed, and sealing is poor, and Applicable scope is little, the problem that intensity is low.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of simple and reasonable, easy for installation and applied widely Novel joint is provided.
For achieving the above object, the utility model has adopted following technical proposal: this Novel joint, comprise Female connector fittings, described Female connector fittings two ends are respectively equipped with the first cylinder and the second cylinder, be provided with the first outside thread on the first cylinder, be provided with the second outside thread on the second cylinder, it is characterized in that, by the end be connected with Female connector fittings, the external diameter to the other end diminishes described the first cylinder gradually, and the external diameter of the end that is connected with Female connector fittings of described the first cylinder equates with the external diameter of the second cylinder.
In above-mentioned Novel joint, the 1.25-1.5 of the external diameter that the external diameter of the end that described the first cylinder is connected with Female connector fittings is the other end doubly.
In above-mentioned Novel joint, the 1.5-2 of the length that the length of described the first cylinder is the second cylinder doubly.
In above-mentioned Novel joint, be provided with the first through hole of axial setting in described the first cylinder, the second through hole that is provided with axial setting in described the second cylinder and is connected with the first through hole, and the aperture that is the second through hole, the aperture of described the first through hole 2/3rds.
In above-mentioned Novel joint, the center line of described the first through hole overlaps with the center line of the second through hole.
In above-mentioned Novel joint, described the second cylinder end is provided with tapered guide head and is connected as a single entity structure with described guide head and the second cylinder.
Compared with prior art, the advantage of this Novel joint is: simple and reasonable, the end that the external diameter of the first cylinder is less makes easier for installation with the guide head be arranged on the second cylinder, installation efficiency improves greatly, makes this joint have stronger sealing simultaneously, is difficult for occurring leakage phenomenon, applied widely, intensity is high, and cost is low, long service life.
The accompanying drawing explanation
The structural representation that Fig. 1 provides for the utility model.
In figure, Female connector fittings 1, the first cylinder 2, the first outside thread 21, the second cylinder 3, the second outside thread 31, the second through hole 32, guide head 33.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, this Novel joint, comprise Female connector fittings 1, Female connector fittings 1 two ends are respectively equipped with the first cylinder 2 and the second cylinder 3, be provided with the first outside thread 21 on the first cylinder 2, the external diameter to the other end diminishes gradually by the end be connected with Female connector fittings 1 to be provided with the second outside thread 31, the first cylinder 2 on the second cylinder 3, and the external diameter of the end that is connected with Female connector fittings 1 of the first cylinder 2 equates with the external diameter of the second cylinder 3.
As a kind of technological scheme of comparatively optimizing, the 1.25-1.5 of the external diameter that the external diameter of the end that the first cylinder 2 in the present embodiment is connected with Female connector fittings 1 is the other end doubly.The 1.5-2 of the length that the length of the first cylinder 2 is the second cylinder 3 doubly.Be provided with the first through hole of axial setting in the first cylinder 2, the second through hole 32 that is provided with axial setting in the second cylinder 3 and is connected with the first through hole, and the aperture that is the second through hole 32, the aperture of the first through hole 2/3rds.The center line of the first through hole overlaps with the center line of the second through hole 32.The second cylinder 3 ends are provided with tapered guide head 33 and are connected as a single entity structure with guide head 33 and the second cylinder 3.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more been used the terms such as Female connector fittings 1, the first cylinder 2, the first outside thread 21, the second cylinder 3, the second outside thread 31, the second through hole 32, guide head 33, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
