FIG. 1 shows an assembled view of an adapter according to one embodiment of the present invention. FIG. 2 shows a cross-sectional view of an adapter of one embodiment of the present invention. FIG. 3 illustrates a state diagram for use of an adapter in accordance with one embodiment of the present invention. As shown, an adapter 100 for clamping a line connection generally comprises a base 101, a drive assembly 102, a resilient member 103, and a swivel nut 104.
The base 101 includes a base 105, a top 106, and a central axis 107. The bottom end of the central shaft 107 is fixed at the central position of the base 105, and the top end of the central shaft 107 is matched and fixed with the top seat 106. The base 105 is substantially parallel to the top base 106 and the central axis 107 is perpendicular to the base 105 and the top base 106.
The drive assembly 102 includes a push nut 108 having a hollow structure and a top block 109. The top block 109 is fixed at the bottom of the pushing nut 108, the pushing nut 108 and the top block 109 are sleeved on the central shaft 107, and the pushing nut 108 can slide up and down along the central shaft 107. The top block 109 is in a hollow circular truncated cone shape, and the pushing nut 108 drives the top block 109 to slide up and down.
The elastic member 103 has a hollow cylindrical shape. The elastic element 103 is sleeved on the conical wall of the top block 109, and the inner wall of the elastic element is matched with the conical wall of the top block 109 in shape. Specifically, the inner wall of the elastic element 103 forms a conical surface, which is spread out into a fan shape. The conical wall of the top block 109 is in contact engagement with the inner wall of the resilient element 103.
The rotating nut 104 is formed in a hollow ring shape, and is fitted around the center shaft 107 at a spacing. The spin nut 104 is rotatably engaged with the top seat 106, and the inner wall of the spin nut 104 is threadably engaged with the outer wall of the push nut 108. Turning the spin nut 104 can cause the push nut 108 to move up and down along the central axis 107.
The elastic element 103 is located between the base 105 and the swivel nut 104. When it is desired to grip a pipe fitting, the side of the adapter 100 containing the resilient element 103 may be inserted into the pipe fitting. The rotating nut 104 is rotated to drive the pushing nut 108 to move toward the base 105. The inner wall of the top block 109 is matched with the inner wall of the elastic element 103, and the elastic element 103 is extruded from inside to outside, so that the elastic element 103 deforms outwards along the radial direction of the central shaft 107, and the periphery of the elastic element 103 is tightly tensioned on the inner wall of the pipeline joint. The adapter 100 holds the line connection in an internal expanding manner. Due to the deformation performance of the elastic element 103, the adapter 100 can be suitable for clamping various types of pipeline joints by moving the top block 109 up and down, and the adapter 100 can be combined with a detection system to conveniently detect the aviation pipeline.
Preferably, a mounting hole 110 is formed in the center of the top base 106. The top end of the central shaft 107 extends into the mounting hole 110 and is fixed in threaded engagement with the mounting hole 110. The top seat 106 is adjusted in its position on the central shaft 107 by means of the mounting hole 110. By way of example and not limitation, after the position of the top seat 106 is adjusted, the relative positions of the central shaft 107 and the top seat 106 may be fixed by fixing pins. After the adapter 100 is assembled, the top seat 106 is adjusted and fixed, and the distance from the top surface of the top seat 106 to the bottom surface of the base 105 is the length of the adapter 100. It will be readily appreciated that turning the spin nut 104 to adjust the resilient member 103 during the pipe gripping process does not affect the length of the adapter 100. The length of the adapter 100 may be used for subsequent testing operations, eliminating the need for the testing system to identify a particular splice type.
Preferably, the top seat 106 extends downward to form a first connecting portion 111, and the spin nut 104 extends upward to form a second connecting portion 112. The first connecting portion 111 and the second connecting portion 112 are rotationally engaged. Because the top seat 106 and the central shaft 107 are fixed in position, the rotating nut 104 cannot move along the radial direction of the central shaft 107, but can only rotate axially to drive the pushing nut to move up and down. Preferably, the outer wall of the first connecting portion 111 is formed with a first annular groove 113, the inner wall of the second connecting portion 112 is formed with a second annular groove 114, and the first annular groove 113 and the second annular groove 114 are opposite. The outer wall of the first connecting portion 111 and the inner wall of the second connecting portion 112 are engaged, and the first ring groove 113 and the second ring groove 114 form an annular passage in which a retainer ring 115 is disposed. This configuration maintains the top seat 106 and the spin nut 104 in a running engagement.
Preferably, the adapter 100 also includes a stop 116. The stopper 116 is disposed between the rotating nut 104 and the elastic element 103. Thus, the elastic member 103 is constrained between the stopper 116 and the base 105, and the elastic member 103 cannot move in the axial direction of the central shaft 107 but can expand or contract in the radial direction of the central shaft 107 only by deformation.
Preferably, a first engaging groove 117 is formed on the surface of the base 105 along the radial direction of the central axis 107. A first protrusion 118 is provided on the lower bottom surface of the elastic element 103, and the first protrusion 118 falls into the first slot 117, and the two cooperate to limit the deflection of the elastic element 103 relative to the central axis 107. Specifically, when the elastic element 103 moves along the radial direction of the central shaft 107 in a deformation manner, the elastic element 103 is ensured not to deflect or displace from the central shaft 107 when expanding or contracting due to the sliding fit between the first protrusion 118 and the first slot 117.
Preferably, a second engaging groove 119 is formed on the bottom surface of the stopper 116 along the radial direction of the central shaft 107. The top surface of the elastic element 103 is provided with a second protrusion 120, the second protrusion 120 falls into the second slot 119, and the two are matched to limit the elastic element 103 from deflecting relative to the central shaft 107, so as to further ensure that the elastic element 103 does not deflect from the central shaft 107 when expanding or contracting. Obviously, the first protrusion 118, the first locking groove 117, the second protrusion 120 and the second locking groove 119 may be provided in plural numbers, and are uniformly arranged along the circumferential direction of the above components, so as to ensure that the expansion or contraction force of the elastic element 103 in each direction is balanced, and does not deflect or displace with the central shaft 107.
Preferably, the top block 109 is in the shape of a truncated cone. Referring to fig. 2, the diameter of the upper bottom surface of the top block 109 is larger than the diameter of the lower bottom surface. When the ejector block 109 moves downward, the ejector spring 103 expands outward.
The use of the adapter 100 is described in detail below with reference to all of the figures.
1. As shown in fig. 1, the adapter 100 is assembled, the position of the top seat 106 on the central shaft 107 is adjusted and fixed, and the length of the adapter 100 is calculated.
2. After the pipeline is welded, the bottom of the adapter 100 is inserted into the pipeline joint, the bottom of the adapter 100 comprises a base 105, an elastic element 103 and a stop 116, and the insertion angle of the adapter 100 is properly adjusted, so that the adapter 100 is inserted without clamping stagnation.
3. Referring to fig. 3, the spin nut 104 is rotated upward along the page in the direction indicated by the arrow on the spin nut 104. Referring to fig. 2, the rotating nut 104 and the pushing nut 108 are threadedly engaged to move the pushing nut 108 toward the base 105. The inner wall of the top block 109 is matched with the inner wall of the elastic element 103, and in the downward moving process, the elastic element 103 is extruded from inside to outside, so that the elastic element 103 deforms outwards along the radial direction of the central shaft 107, the phi A is increased, and the periphery of the elastic element 103 is tightly tensioned on the inner wall of the pipeline joint. The adapter 100 and the pipe joint are tightened by gripping the top seat 106 of the adapter 100 and forcibly rotating the spin nut 104 of the adapter 100. When the adapter 100 and the pipe joint need to be loosened, corresponding reverse operation is carried out, the rotating nut 104 is rotated reversely, the outward expansion force of the elastic element 103 is relieved, the phi A is reduced, and the adapter 100 and the pipe joint are separated.
The adapter 100 provided by the present invention has the following advantages:
1. the whole structure is compact, and the assembly and the use are convenient.
2. The universal joint has universality and is suitable for different pipeline joints.
3. Durable and adjustable length, the laminating degree with the pipeline connects is high, and measurement accuracy is controllable.
