Abstract
The invention discloses an external connecting type buckle structure. The external connecting type buckle structure comprises an MDM1818-A body, and is characterized in that through holes are formed in the inner walls of the two ends of the MDM1818-A body, and sealing rings are arranged in the two ends of each through hole; claws are buckled on a buckle cap; three buckles are evenly distributed on the inner ring of the buckle cap and forcefully clamped on an outer groove of the MDM1818-A body; and the structural strength is high, and the buckle cap cannot fall off. The external connecting type buckle structure has the beneficial effects that a buckle cap in the prior art is welded to the body through ultrasonic waves, consequently, the defects that dry joint is liable to happen and welding is not firm are caused, the buckle cap in the external connecting type buckle structure is clamped on the body, and therefore the problem is solved, installing is convenient, and the production efficiency is high; and the outer walls of the sealing rings and the inner wall of the body are in face contact, the larger the pressure in a pipe is, the higher the compression ratio of the contact faces of the outer walls of the sealing rings and the inner wall of the body becomes, sealing is better, and water leakage is not liable to happen.
Description
Technical field
The present invention relates to a kind of externally connected type buckle structure.
Background technique
At present for Related products such as water purifiers, the sealing of pipeline is most important, and most product easily leaks at pipe joint place, leaks gas, and all brings much unnecessary trouble to Consumer and manufacturer.Pipe connector on market is generally divided into two kinds; Original nut lock compact form pipe connector and common claw band locking plate pipe connector.
For nut lock compact form pipe connector, there is following defect: 1, owing to being that clamping type connects, high to the quality requirement of pipe, pipe diameter, slightly larger than normal specifications, may be inserted to enter, and diameter is smaller, connects instability, causes and leaks; 2, the coaxality of pipe requires high, if pipe thickness is uneven, can unbalance stress, and cause and leak; 3, sealing is relevant with the degree of tightness of nut, and twist and tightly then can not leak, installing each root pipe all needs fastening nut as requested, and working efficiency is low, and the poor stability of product; 4, the hardness requirement of tubing is high, if hardness is inadequate, then repeatedly use same pipe, can cave in joint, thus leak, and which adds the cost retubed.
For common claw band locking plate pipe connector, although pipe grafting is convenient, also there is following defect:
1: the quick pipe connecting piece of this structure, general employing ultrasonic welding connects original and lid.This Placement easily causes rosin joint and weldering loosely.2: ultrasonic welding easily produces welding slag, easily cause when welding slag is fallen into inside pipe connector leaking.3: after ultrasonic welding, part material characteristic is changed, thus the intensity and the toughness that affect product.4: when produced in large volumes, increase cost of production, ultrasonic welding machine in enormous quantities be bought, also increase maintenance cost.
Summary of the invention
For problems of the prior art, object of the present invention provides a kind of external clamping type structure, this structural advantages: 1: this structure adopts external clamping type to connect, and there is not rosin joint and welds loosely phenomenon.2: each port that connects soon of this structure has 2 seal rings, greatly reduces water leakage ratio.3: this structure adopts external clamping type to connect, and can not change intensity and the toughness of product.4: during production in enormous quantities, cost of production easy for installation is low, and manufacturing efficiency is high.
