Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, and particularly to fig. 3 and 6, a fracture-preventing joint is known, which includes a main body 1, wherein a movable rod 2 is disposed in the main body 1, and the main body 1 is provided with a connecting groove 3 for connecting with a water pipe of a washing machine, i.e., the water pipe is firstly sleeved on the outer side of the main body 1 and then connected through a connecting piece such as a snap ring, and the snap ring is firstly sleeved on the water pipe, and then when the water pipe is sleeved on the main body 1, the connecting groove 3 is clamped through the snap ring, so as to dispose the water pipe on the main body 1.

In the actual use process, whether water is discharged or not is controlled through the height of the movable rod 2. As shown in fig. 6, it can be seen that the movable rod 2 is provided with a water stop portion 18 at the top, a water outlet 8 at the bottom, and a plurality of water inlets 9 for water circulation at the periphery. So that only when the movable lever 2 is moved upward so that the water stop portion 18 is no longer abutted against the inside of the main body 1 and the water inlet 9 is exposed, thereby forming a water flow passage, i.e., water enters the movable lever 2 from the water inlet 9 and then enters the water pipe from the water outlet 8. The specific process is as follows:

when the movable rod 2 moves to the highest point, a water flowing channel is formed, water can flow through, then the water faucet is opened, two sides of the water inlet 9 on the movable rod 2 are not in contact with the inside of the movable rod 2, the water stopping part 18 is not abutted against the inner side of the main body 1, a water flowing space exists, water can flow into the movable rod 2 from the water inlet 9 and then flows out from the water outlet 8, and therefore the water enters the washing machine and further washes clothes.

The principle of the simultaneous upward movement of the movable bar 2 is as follows: firstly, the diameter size of the water pipe is between the diameter size of the main body 1 and the diameter size of the movable rod 2, and the diameter size of the main body 1 and the diameter size of the movable rod 2 have a certain difference but have small difference. Therefore, in the sleeving process, the movable rod 2 can be pushed to move upwards through the water pipe and can be sleeved on the main body 1, so that water is communicated. If the water tap is opened at the moment, the water inlet of the washing machine is realized, and then the water tap is closed, and the water inlet is stopped.

And when the movable rod 2 moves to the lowest point, the water flowing channel is disconnected, and the water stop state is realized. At this time, both sides of the water inlet 9 are in a contact state with the inside of the movable rod 2, and no water flowing space exists, so that water is blocked at the upper end by the movable rod 2 and does not flow out, and water stop is formed.

Meanwhile, the principle that the movable rod 2 moves downwards is as follows: first, the water pipe is separated, so that the water pressure of the main body 1 is different from the upper water pressure and the lower water pressure, and the movable rod 2 is pushed by the larger water pressure to move downwards because the upper water pressure is higher than the lower water pressure. Meanwhile, the movable rod 2 is provided with a water stopping part 18, so when the movable rod 2 moves to the lowest point, the water stopping part 18 abuts against the inner side of the main body 1, thereby stopping water above the water stopping part 18, namely, the water is blocked at the upper end by the movable rod 2, so that the water does not flow out, thereby forming water stopping.

The event the utility model discloses a simple structure, when can guarantee the stability of structure, processing and installation are all more convenient.

And when the main part 1 is in the stagnant water state, when the joint is in the state that can not lead to water, the main part sets up connecting groove 3 because the height is less than the height of stagnant water portion 18, so accessible stagnant water portion 1 water stops water on connecting groove 3 end to no rivers pass through in making connecting groove 3, and can not form near connecting groove 3 water pressure and pile up, so can not lead to the fracture because water pressure is too big. Originally compares, because the activity pole 2 blocks water in that section region that main part 1 set up connecting groove 3, therefore can lead to the fracture because water pressure is too big, and the utility model discloses this kind of condition has been avoided.

Meanwhile, if the connecting groove 3 is broken due to the fact that the connecting groove is too deep and the wall thickness is thin, the novel water stopping part 18 is higher than the connecting groove 3, so that the water stopping part 18 can stop water at the upper end of the connecting groove 3, water flow does not pass through, and water can be stopped even if the connecting groove is broken.

Further, as shown in fig. 2 and 4, it can be seen that the main body 1 has a through hole 10 formed therein, and the movable rod 2 is disposed in the through hole 10 and moves up and down in the through hole 10. And the through hole 10 includes a mounting area 11, a limiting area 12 and a connecting area 13, the limiting area 12 is disposed between the mounting area 11 and the connecting area 13, and the movable rod 2 is disposed in the mounting area 11. While a transition zone 14 is provided between the confinement zone 12 and the mounting zone 11.

And with reference to fig. 2 and 4, and specifically to fig. 3 and 5, it can be seen that the connection and limiting structure between the movable rod 2 and the main body 1 specifically includes:

at first when the utility model discloses be in when leading to water, as shown in fig. 4, specifically see fig. 5, 2 bottoms of movable rod are supported and are leaned on in 1 bottom of main part this moment, and 2 bottoms of movable rod have seted up mounting groove two 7, and in two 5 joint mounting grooves two 7 of locating part simultaneously, support and lean on in 1 bottom terminal surface of main part through two 5 of locating part to restriction movable rod 2 breaks away from main part 1. And the second limiting part 5 is detachable, so that when the movable rod 2 is damaged, the movable rod 2 can be taken down for replacement as long as the second limiting part 5 is taken down.

Secondly, when the utility model is in the water stopping, namely the joint can not lead to water, as shown in fig. 2, specifically see fig. 3, the water stopping part 18 is leaned against the inner side of the main body 1. The specific point is that the water stop part 18 abuts against the transition area 14, and the transition area 14 is a circular arc inclined surface, so that scratches cannot be caused by edges and the like during limiting.

Meanwhile, the water stop part 18 is provided with a first mounting groove 6, and a first limiting part 4 is clamped in the first mounting groove 6 and abuts against the inner side of the main body 1, namely the transition area 14, through the first limiting part 4, so that the movable rod 2 is limited to be separated from the main body 1. The event the utility model discloses a simple structure, when can guarantee the stability of structure, processing and installation are all more convenient.

Referring to fig. 2 and 4, it can be seen that a thread 15 for connection is formed in the connection region 13, and the thread 15 is used for connecting a faucet. And avoid the connection between the two to leak, and then be provided with sealing washer 16 in joining region 13, and joining region 13 is provided with boss 17, and sealing washer 16 places on boss 17 simultaneously, thereby makes boss 17 carry out spacing and prevent sealing washer 16 to sealing washer 16. The event the utility model discloses a simple structure, when can guarantee the stability of structure, processing and installation are all more convenient.

The specific working process of the scheme is as follows:

the utility model provides a prevent cracked joint, includes main part 1, wherein removes in the main part 1 and is provided with movable rod 2, and main part 1 offers the spread groove 3 that is used for external washing machine water pipe, and the water pipe cup joints earlier on the 1 outside of main part promptly, then connects such as snap ring etc. through the connecting piece, and the snap ring overlaps earlier and establishes on the water pipe moreover, then when the water pipe cup joints on main part 1, advances spread groove 3 through the snap ring joint to set up the water pipe on main part 1.

In the actual use process, whether water is discharged or not is controlled through the height of the movable rod 2. The specific process is as follows:

when the movable rod 2 moves to the highest point, a water flowing channel is formed, and water can be further led. Then, the water tap is opened again, and at this time, water flows out from the water tap into the main body 1, flows into the water pipe from the main body 1, and flows into the washing machine, thereby washing the laundry.

And when the movable rod 2 moves to the lowest point, the water flowing channel is disconnected, and the water stop state is realized. The principle is as follows: first, the water pipe is separated, so that the water pressure of the main body 1 is different from the upper water pressure and the lower water pressure, and the movable rod 2 is pushed by the larger water pressure to move downwards because the upper water pressure is higher than the lower water pressure. Meanwhile, the movable rod 2 is provided with a water stopping part 18, so when the movable rod 2 moves to the lowest point, the water stopping part 18 abuts against the inner side of the main body 1, thereby stopping water above the water stopping part 18, namely, the water is blocked at the upper end by the movable rod 2, so that the water does not flow out, thereby forming water stopping.

And when the main body 1 is in the water stopping state, namely when the joint is in the state of water can not pass, the connecting groove 3 arranged on the main body 1 is lower than the water stopping part 18, so the water can be stopped at the upper end 3 of the connecting groove by the water stopping part 18, no water flow passes through the connecting groove 3, and the water pressure accumulation can not be formed near the connecting groove 3, so the fracture can not be caused by the overlarge water pressure. Originally compares, because the activity pole 2 blocks water in that section region that main part 1 set up connecting groove 3, therefore can lead to the fracture because water pressure is too big, and the utility model discloses this kind of condition has been avoided.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
