[0029] As attached Figure 1-6 A modular multi-channel quick connection device is shown, which includes a plurality of connection units 1 , each of which includes a connecting seat 11 and a connecting pipe 12 .

[0030] The connecting seat 11 is provided with a through hole 111 and a mounting hole 112 that penetrate the connecting seat 11. The end surface of the connecting seat 11 is provided with a through hole 111, and the through hole 111 is used to flow through gas or liquid. The mounting hole 112 is penetrated by a bolt 1121, and the end of the bolt 1121 is threadedly connected with a nut 1122. Through the bolt 1121, a plurality of connecting monomers 1 can be linearly connected and combined in one direction, and the nut 1122 is used to tighten the plurality of connecting monomers 1, thereby meeting different requirements for the number of connecting monomers 1 in different usage scenarios.

[0031] In some embodiments, through holes 111 and mounting holes 112 are provided on both end surfaces of the connecting seat 11 , so as to realize the connection and combination of a plurality of connecting monomers 1 on straight lines in two directions.

[0032] The connecting pipe 12 is symmetrically provided with two upper and lower sealing grooves 121 with its central axis as the symmetry axis, and the upper and lower sealing grooves 121 are both sleeved with first sealing rings 122. When in use, the connecting pipe 12 is inserted into the through hole 111. The first sealing ring 122 is provided when the through hole 111 is connected, which can improve the sealing effect and avoid leakage of gas or liquid.

[0033] The connecting seat 11 is provided with a flow regulating component connected with the through hole 111 , and the flow of the gas or liquid flowing out of the through hole 111 can be regulated by the flow regulating component.

[0034] In some embodiments, the ends of the connecting pipe 12 are designed with bevels, which makes the connection more precise and firm, while avoiding the risk of damaging the first sealing ring 122 .

[0035] In some embodiments, the flow regulating component includes a liquid flow pipeline and a valve core. The liquid flow pipeline includes an inlet pipe 21 and an outlet pipe 22. The valve core includes an inner core tube 23 arranged in a vertical direction. The inner core tube 23 is made of flexible material. The inlet pipe 21 and the outlet pipe 22 are connected through the inner core tube 23. The upper and lower ends of the inner core tube 23 are both set as flow sections 231. The middle part of the inner core tube 23 is set as an adjustment section 232. The adjustment section 232 has flow guide holes 2321 evenly distributed along the circumference and passing through the adjustment section 232. The flow guide holes 2321 are correspondingly connected to the flow sections 231 at the upper and lower ends. The ends of the flow sections 231 are sleeved with the corresponding ends of the inlet pipe 21 and the outlet pipe 22. The upper and lower ends of the outer part of the inner core tube 23 are respectively sleeved with sealing sleeves 31, and a locking assembly is arranged between the upper and lower sealing sleeves 31.

[0036] In some embodiments, the inner core tube 23 is made of silicone.

[0037] like Figure 1 As shown, the flow regulating component is arranged in the vertical axial position of the liquid inlet pipe 21, and occupies little external space. Therefore, it can be arranged on a pipeline system that requires dense connection, avoiding mutual interference between the connected monomers 1. Compared with the use of traditional flow regulating valves for regulation, the application scope of the utility model is wider.

[0038] In some embodiments, a connecting thread 221 and a second sealing ring 222 are provided at the end of the liquid outlet pipe 22. When connecting the pipeline, the connecting thread 221 and the second sealing ring 222 can ensure the stability of the connection and good sealing performance, thereby avoiding gas or liquid leakage under high pressure conditions.

[0039] In some embodiments, the locking assembly includes a fixed sleeve 32 sleeved and fixed on the outer wall of the middle part of the adjustment section 232, the fixed sleeve 32 is coaxially arranged with the sealing sleeves 31 at the upper and lower ends, the outer part of the fixed sleeve 32 is slidably sleeved with a twisting sleeve 33 in the vertical direction, a limit baffle 34 is arranged below the twisting sleeve 33, a locking ring 35 is arranged above the twisting sleeve 33, the limit baffle 34 is sleeved and fixed on the outer part of the sealing sleeve 31 at the lower end, and the locking ring 35 is sleeved and fixed on the outer part of the sealing sleeve 31 at the upper end. A spring 36 is arranged between the twisting sleeve 33 and the limit baffle 34, the upper end surface of the twisting sleeve 33 is uniformly distributed with insert teeth 331 along the circumferential direction, the locking ring 35 is uniformly distributed with tooth grooves 351 along the circumferential direction, and the insert teeth 331 and the tooth grooves 351 are meshed with each other.

[0040] When the flow rate needs to be adjusted, the twisting sleeve 33 is twisted in the circumferential direction, and then the fixed sleeve 32 drives the inner core tube 23 of the flexible material to rotate around its axis. In this process, the liquid inlet pipe 21 is fixed to the connecting seat 11, and the liquid outlet pipe 22 is fixedly connected to the equipment to be used; therefore, the liquid inlet pipe 21 and the liquid outlet pipe 22 will not rotate with the rotation of the inner core tube 23. Since the two ends of the inner core tube 23 are fixed by the sealing sleeve 31 and the inner core tube 23 is a flexible material, the rotation of the inner core tube 23 will be converted into torsion. Furthermore, the guide holes 2321 arranged on the adjustment section 232 are evenly elongated during torsion, and the cross-sectional area of ​​the guide holes 2321 gradually decreases, and the resistance to the fluid flowing through the guide holes 2321 continues to increase, thereby achieving the purpose of linear regulation of the fluid flow.

[0041] In order to prevent the inner core tube 23 from automatically resetting under its own torsional force after the adjustment is completed, a locking assembly is provided. When the twisting sleeve 33 needs to be twisted, the twisting sleeve 33 is first moved downward along its axis, and the spring 36 is compressed, so that the inserting teeth 331 on the twisting sleeve 33 are disengaged from the tooth grooves 351 in the locking ring 35, and the twisting ring 33 can rotate at this time; after the adjustment is completed, the twisting sleeve 33 is moved upward under the elastic force of the spring 36, and then the inserting teeth 331 and the tooth grooves 351 are meshed with each other, so that the twisting ring 33 cannot be further rotated due to the restriction of the locking ring 35, so that the adjustment state can be locked.

[0042] When the regulating assembly needs to be reset to the maximum flow rate, the screw sleeve 33 is moved downward. When the insert teeth 331 are separated from the tooth grooves 351, the inner core tube 23 can be reset with the help of the flexible torsional force of the inner core tube 23, so that the liquid flow rate can be easily restored to the maximum.

[0043] In some embodiments, the twisting sleeve 33 is provided with an indicator line 332, and the upper end surface of the locking ring 35 is provided with a scale line 352. Through the cooperation between the indicator line 332 and the scale line 352, when a large number of connected monomers 1 are connected, the operator can quickly and clearly observe the flow opening of the flow regulating component, thereby improving the adjustment efficiency.

[0044] In some embodiments, the twist sleeve 33 is provided with anti-slip raised patterns to facilitate the use of the operator.

[0045] The working principle of the utility model is as follows:

[0046] During connection, a connecting tube 12 is inserted between the through holes 111 of every two connecting monomers 1, and the multiple connecting monomers 1 are interconnected through the connecting tube 12, and gas or liquid can flow between the multiple connecting monomers 1. After the connecting tube 12 is connected, the multiple connecting monomers 1 are fixed in a straight line direction by bolts 1121 and nuts 1122 passed through the mounting holes 112.

[0047] The connecting seat 11 is provided with a flow regulating assembly connected to the through hole 111, and the fluid flowing out of the through hole 111 is regulated by the flow regulating assembly. When the operator needs to adjust the flow rate, the screw sleeve 33 is first moved downward along its axis to compress the spring 36, so that the insert 331 on the screw sleeve 33 is disengaged from the tooth groove 351 in the locking ring 35, and then the screw sleeve 33 is rotated in the circumferential direction. Since the two ends of the inner core tube 23 are fixed by the sealing sleeve 31 and it is a flexible material, the rotation of the inner core tube 23 will be converted into torsion, resulting in a smaller flux. At the same time, the guide hole 2321 on the regulating section 232 is evenly elongated during torsion, the cross-sectional area becomes smaller, and the resistance increases when the fluid flows through, thereby realizing the regulation of the liquid flow rate. By cooperating with the indicator line 332 and the scale line 352, the operator can accurately adjust the flow regulating component to the required flow opening. After the adjustment is completed, under the elastic force of the spring 36, the screw sleeve 33 moves upward, and then the insert tooth 331 and the tooth groove 351 engage with each other, thereby locking the adjustment state and stably maintaining the adjusted flow opening.

[0048] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
