Abstract
The utility model provides a self-locking type pipe joint. The self-locking type pipe joint comprises a pipe-like joint main body of which two ends are provided with pipe connection threads respectively, wherein the pipe connection nuts available for thread spinning connection are arranged on two ends of the pipe-like joint main body respectively; oblique mouths are arranged on the internal surfaces at the end sides of two ends of the pipe-like joint main body respectively; self-locking rings of which the internal diameters can be decreased and which are ejected against the oblique mouths when the pipe connection nuts are connected with the ends of the pipe-like joint main body in a spinning way, are arranged in internal holes of the pipe connection nuts; each self-locking ring is an open ring; and an opening in each open ring is in a nonlinear shape that two ends of the opening are arranged in a staggering way. The self-locking type pipe joint has the characteristics of simple and rational structure, practicability and convenience in application, easiness in processing, flexibility in detachment, rapidness in connection, no adhesion and welding, good sealing effect and the like; the self-locking type pipe joint can be widely used for the rapid installation construction of water, gas and heating pipelines for industrial, agricultural, mineral and civil appliances; and therefore, the popularization and use values are good.
Description
Technical field
The utility model relates to a kind ofly along with swivel nut motion and can pin the pipe joint of adapter, belong to a kind of pipe and be hinged with and put.
Background technique
The connected element that is used between body and the body is used very generally, and application area also more and more widely.Joint of a great variety, of all kinds.Weld-end fittings, threaded fitting, cutting ferrule pipe fitting and clip pipe fitting etc. are arranged.Common joint defective such as is fastenedly connected because the workman need just can make by means of other instrument between the body when carrying out the pipe fitting operation.And press for a kind of under the situation of not using any instrument, can be fast, simple, repeat to connect and the joint of work such as disconnection to insurance.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that existing technology exists, and is provided and need be by means of a kind of self-locking pipe joint of other instrument a kind of can the connection fast.
The following technological scheme of passing through of the utility model is accomplished; A kind of self-locking pipe joint; It comprises that two ends are shaped on the tubular configured joint body that pipe connects screw thread; But the two ends at said tubular configured joint body dispose the union nut that screw thread spins respectively; Be shaped on angle respectively on the end limit internal surface at described tubular configured joint body two ends, in the endoporus of said union nut, dispose one when union nut is screwed in the tubular configured joint body end, by roof pressure self-locking ring on angle, that can dwindle internal diameter.
Described self-locking ring is a trip ring, and the opening on the trip ring is the non-linear shape that two ends are staggeredly arranged.
It has simple and reasonable for structure; Practical and convenient reliable; Be easy to processing, dismantle flexibly, connect fast, need not glue, weld; Characteristics such as good sealing effect can be widely used in water, the gas of industry, agricultural, mine and civilian installation, the quick mounting construction in heating coil road, have good value for applications.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Reference character among the figure is:
1, pipe connects screwed pipe; 2, joint body; 3, nut; 4, angle; 5, self-locking ring; 6, opening contact pin.
Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: self-locking pipe joint shown in Figure 1; It comprises that two ends are shaped on the tubular configured joint body 2 that pipe connects screw thread 1; But dispose the union nut 3 that screw thread spins respectively at the two ends of said tubular configured joint body 2; Be shaped on angle 4 respectively on the end limit internal surface at described tubular configured joint body 2 two ends; In the endoporus of said union nut 3, dispose one when union nut 3 is screwed in tubular configured joint body 2 ends, by roof pressure self-locking ring 5 on angle 4, that can dwindle internal diameter.
Described self-locking ring 5 is a trip ring, and the opening on the trip ring 6 is the non-linear shape that two ends are staggeredly arranged.Said self-locking ring 5 can advance and pressurized along with union nut 3 rotates in tubular configured joint body 2; And under the effect of angle 4; Opening 6 on the self-locking ring 5 is slowly closed; Form the undergauge process of self-locking ring 5, connect by self-locking ring 5 and hold tightly being plugged on pipe in the union nut, the pipe that reaches self-locking connects purpose.
Above content is the further explain that combines concrete mode of execution that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
Claims (2)
1. self-locking pipe joint; It comprises that two ends are shaped on the tubular configured joint body (2) that pipe connects screw thread; At said tubular configured joint body (2) but two ends dispose the union nut (3) that screw thread spins respectively; It is characterized in that being shaped on angle (4) respectively on the end limit internal surface at described tubular configured joint body (2) two ends; In the endoporus of said union nut (3), dispose one when union nut (3) is screwed in tubular configured joint body (2) end, by roof pressure self-locking ring on angle (4), that can dwindle internal diameter (5).
