Description

pipe connector

technical field

The utility model belongs to a pipe joint, in particular to a water pipe joint.

Background technique

As shown in Figure 1 and Figure 2, the two ends of the commonly used water pipe joints can respectively be used to connect flexible water inlet pipes or water spray pipes, which have a hollow body 10 forming a through hole 102 and a flange 103, and one end of the body 10 A water inlet connector 101 that can cooperate with the locking cap 2 to connect with the soft water inlet pipe is formed, and the other end is formed with a small diameter and a spring 17 is sheathed on the outer periphery, and a three-dimensional wall with two soft track walls 11 is formed on the outer periphery at an appropriate position. Telescopic hole 12, wherein, two soft track walls 11 are tied at appropriate positions to form a track groove 110, and at the same time, a pushed piece 13 with a locking block 130 is set in the track groove 110, and the locking block 130 can protrude from the telescopic hole 12 , retract; the outer periphery of the body 10 is provided with a control sleeve 14, and the inner periphery of the control sleeve 14 is provided with a pushing piece 15 that can push the pushed piece 13 according to the operation. When the fixed piece 16 and the control sleeve 14 are combined with the main body 10, the blocking piece 16 is resisted on the joint flange 103 of the main body 10, so that the control sleeve 14 can be pressed and the spring 17 can be released but will not be affected by the spring 17 And break away from the body 10 . When in use, the user directly operates the control sleeve 14 to retreat and compress the spring 17, so that the pushing piece 15 does not press the pushed piece 13 accommodated in the track groove 110 of the body 10, so as to control the locking block 130 to retreat into In the telescopic hole 12, the water outlet joint 1 can be inserted into the through hole 102 of the body 10, and then the control sleeve 14 is loosened. The control sleeve 14 advances under the elastic force of the spring 17, and is pressed and pushed by the inner peripheral push piece 15. piece 13, so that the locking block 130 of the pushed piece 13 extends out of the telescopic hole 12, and is stuck in the groove on the outer periphery of the water outlet connector 1, so as to connect the water outlet connector 1 and the body 10 into one; A water spray head or a flexible water pipe is installed on the head 1, so that the water inlet pipe communicates with the water outlet connector 1 through the body 10. Though the water pipe joint of this conventional structure can reach the purpose of connecting, there are following shortcomings in its use:

1. It must be assembled with a plurality of scattered pushed pieces 13 and springs 17, the combined structure is complicated, the assembly is troublesome, and the assembly cost is high.

2. In order to prevent the pushed pieces 13 from being separated, the control sleeve 14 is provided with a barb-shaped joint blocking piece 16, so that once the control sleeve 14 is integrated with the body 10, it is almost irremovable Therefore, once a fault or blockage occurs, it is extremely difficult to repair and maintain.

3. The control sleeve 14 and each pushed piece 13 are separate, rather than integrally formed. Because two injection moldings are required, the manufacturing cost is relatively high.

Detailed ways

As shown in FIG. 2 and FIG. 3 , the utility model includes a hollow body 20 , a locking cap 2 , a control sleeve 30 and an elastic element 40 .

One end of the main body 20 is a water inlet connector 201, and the other end has outer and inner cylinders 21, 22 forming an appropriate gap 2H. Several chutes 211 are cut around the periphery of the outer cylinder 21, and limit valves are set on both sides of each chute 21. The position edge 212 ; the inner cylinder body 22 is provided with a penetrating telescopic hole 23 and a recessed accommodation groove 24 corresponding to the number chute 211 , and a guiding slope 25 is formed at the junction of the accommodation groove 24 and the telescopic hole 23 .

The control sleeve 30 has an annular connecting ring 31 corresponding to and accommodated in the gap 2H outside the body 20 and between the inner cylinders 21 and 22, and two corresponding track grooves 33 are formed at the place corresponding to the chute 211 of the body 20 Protrusion 32, and make the bottom surface of protrusion 32 form appropriate telescopic groove 34, and from the telescopic groove 34 place inwards equiangular ring cloth obliquely extend the elastic piece 35 that one-piece molded end forms locking block 36.

The elastic element 40 has appropriate stretching elasticity and is correspondingly arranged in the gap 2H outside the body 20 and between the inner cylinders 21 and 22, and its top and bottom ends are respectively against the control sleeve 30 and the body 20, so The sliding displacement of the control sleeve 30 relative to the body 20 is smoother, which helps the locking block 36 to lock and position the water outlet connector 1 more reliably and effectively reduces friction between components to increase its service life.

When assembling, fit the elastic element 40 and the control sleeve 30 in the gap 2H between the outside of the main body 20 and the inner cylinders 21 and 22, and make the two ends of the elastic element 40 bear against the control sleeve 30 and the main body 20 respectively The protrusion 32 of the control sleeve 30 fits on the limit edges 212 on both sides of the outer cylinder 21 of the main body 20 with the track groove 33, and can be slid and displaced according to the operation so that the locking block 36 of the elastic piece 35 can just move Displacement along the accommodation groove 24 of the inner cylinder 22, so that the locking block 36 protrudes from the telescopic hole 23 through the action of the elastic piece 35 and the elastic element 40, and at the same time, the inserted water outlet connector 1 of the card group can be matched with the telescopic groove 34. The accommodating groove 24 of the inner cylinder body 22 does not protrude from the telescopic hole 23, so that the water outlet connector 1 can be disengaged.

The utility model has the following advantages:

As shown in Figure 4, Figure 5, Figure 6, and Figure 7, when in use, the user cooperates with the lock cap 2 to assemble the water inlet connector 201 end of the body 20 into the water pipe, and cooperates with the telescopic hole 23 of the body 20 to assemble the water outlet connector 1 , and make the number locking block 36 of the control sleeve 30 equiangular ring cloth firmly lock and position the water outlet connector 1, and at the same time use the elastic element 40 to effectively reduce the load of the elastic sheet 35 of the control sleeve 30, avoiding the repeated use of the elastic sheet 35 Under use, it gradually loses its proper elastic force, so that the clamping effect of the locking block 36 is reduced or even unable to stably fix the water outlet connector 1 , so that the elastic element 40 and the elastic sheet 35 form a complementary effect. At the same time, the main components of the utility model are only the main body 20, the control sleeve 30, the elastic element 40 and the cover body, thereby simplifying the manufacturing and assembling procedures, saving man-hours and reducing production costs. Easy to assemble, just install the elastic element 40 on the outside of the main body 20 and in the gap 2H between the inner cylinders 21 and 22, and then use the protrusion 32 of the control sleeve 30 to correspond to the two sides of the outer cylinder 21 of the main body 20 and the chute 211. Edge 212 is enough to achieve the practical benefits of firm positioning, convenient and easy use and increased service life.
