[0002] Quick-connect connectors for mechanical hoses play an important role in improving work efficiency, enhancing safety, extending the life of hoses and equipment, adapting to various environments, improving system flexibility, and reducing maintenance costs. Therefore, the application and configuration of quick connectors should be fully considered when designing and selecting mechanical systems.

[0003] A search revealed that, among the prior art, Chinese patent publication number CN213512562U discloses "a quick-connect fitting device, belonging to the field of mechanical equipment technology, wherein when two arc-shaped locking members approach each other, the inner sidewalls of the arc-shaped locking members gradually squeeze the outer sidewall of the hose, locking the hose. The utility model aims to provide a quick-connect fitting device; a locking mechanism is added to the existing quick connector to lock the hose, making it less likely to fall off." However, the following defects still exist:

[0004] (1) After the connection with the hose is completed, the connection is not firm. When in use, the impact of the fluid transmitted in the pipe can easily cause the connector and the hose to separate;

[0005] (2) Since the hose itself is relatively soft, there is a lack of clamping measures for the hose body after connection, and there is a lack of certain sealing measures between the hose and the connector, which can easily lead to fluid leakage after connection.

[0006] Therefore, we have made improvements to this and proposed a quick-connect connector for mechanical hoses. Utility Model Content

[0028] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.

Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0032] See Figures 1 to 8 , the utility model provides a technical solution:

[0033] A quick-connect connector for mechanical hoses, comprising a hose 1, with a connecting mechanism 2 provided at the connection between two sets of hoses 1;

[0034] The connecting mechanism 2 includes a connecting component 201, a clamping component 202 and a sealing component 203. The connecting component 201 includes a trapezoidal connecting column 2011, a first connecting thread 2012, a second connecting thread 2013 and a fixing bolt 2014. The trapezoidal connecting column 2011 is set at the connection point of the two groups of hoses 1. The first connecting thread 2012 is opened on the outside of the lower end of the trapezoidal connecting column 2011, and the second connecting thread 2013 is set on the outside of the wider end of the trapezoidal connecting column 2011. The fixing bolt 2014 is fixedly set in the transition area of the trapezoidal connecting column 2011.

[0035] Specifically, such as Figure 3 As shown, the clamping assembly 202 includes a first clamping bolt 2021, a second clamping bolt 2022, a first clamping thread 2023 and a second clamping thread 2024. The first clamping bolt 2021 is arranged at one end of the trapezoidal connecting column 2011, and the second clamping bolt 2022 is arranged at the other end of the trapezoidal connecting column 2011. The first clamping thread 2023 and the second clamping thread 2024 are respectively opened on the inner sides of the first clamping bolt 2021 and the second clamping bolt 2022.

[0036] Specifically, such as Figure 3and 4 As shown, the sealing assembly 203 includes a sealing ring 2031, a sealing ring 2032 and a transition ring 2033. The sealing ring 2031 is arranged at one end of the trapezoidal connecting column 2011, the sealing ring 2032 is arranged inside the other end of the trapezoidal connecting column 2011, and the transition ring 2033 is installed between the sealing ring 2032 and the trapezoidal connecting column 2011.

[0037] By setting up the connecting mechanism 2, during use, one end of the two groups of hoses 1 are respectively inserted from the two ends of the trapezoidal connecting column 2011, and the connecting heads of the hoses 1 are respectively in contact with the inner walls of the sealing ring 2031 and the sealing ring 2032 to prevent the hoses 1 from directly contacting the metal trapezoidal connecting column 2011. Since the first clamping bolt 2021 and the second clamping bolt 2022 are installed at the two ends of the trapezoidal connecting column 2011, the first clamping thread 2023 and the second clamping thread 2024 correspond to the first connecting thread 2012 and the second connecting thread 2013, and the trapezoidal connecting column 2011 is tightened by rotating the first clamping bolt 2021 and the second clamping bolt 2022.

[0038] Specifically, such as Figure 3 and Figure 4 As shown, an anti-wear pad 3 is provided on the outer side of the trapezoidal connecting column 2011 . The anti-wear pad 3 is made of rubber material and is located between the first clamping bolt 2021 and the transition point of the trapezoidal connecting column 2011 .

[0039] Specifically, such as Figure 3 and Figure 4 As shown, the diameter of one end of the sealing ring 2031 is larger than the inner diameter of the trapezoidal connecting column 2011, and the smaller diameter end of the sealing ring 2031 extends into the distance of one end of the trapezoidal connecting column 2011. One end of the sealing ring 2032 is U-shaped.

[0040] Specifically, such as Figure 3 As shown, a limiting spring 4 is provided inside the trapezoidal connecting column 2011 . The limiting spring 4 is located between the sealing collar 2031 and the sealing ring 2032 and is made of stainless steel.

[0041] Specifically, such as Figure 3 、 Figure 6 and Figure 8 As shown, a placement groove 5 is opened at one end of the trapezoidal connecting column 2011, and a push ring 6 is arranged inside the placement groove 5. One end of the push ring 6 is bent downward to contact the outer side of the sealing ring 2032, and the push ring 6 is arranged obliquely inside the placement groove 5.

[0042] By providing an anti-wear pad 3, the end face friction between the first clamping bolt 2021 and the trapezoidal connecting column 2011 can be reduced. The U-shaped sealing ring 2032 can provide a certain elastic support for one end of the hose 1. The internal limiting spring 4 can prevent excessive contact between the sealing ring 2031 and the sealing ring 2032. At the same time, when the second clamping bolt 2022 rotates, it will drive the push ring 6 to move inward, resist one end of the sealing ring 2032, and further tighten one end of the hose 1.

[0043] Specifically, when using this mechanical hose quick connection connector: insert one end of the two sets of hoses 1 from the two ends of the trapezoidal connecting column 2011 respectively. At this time, the connecting heads of the hoses 1 are in contact with the inner walls of the sealing ring 2031 and the sealing ring 2032 respectively. Turn the first clamping bolt 2021 and the second clamping bolt 2022 to tighten the trapezoidal connecting column 2011. At the same time, when the second clamping bolt 2022 is rotated, it will drive the push ring 6 to move inward, resisting one end of the sealing ring 2032, further tightening one end of the hose 1. The internal limiting spring 4 can prevent excessive contact between the sealing ring 2031 and the sealing ring 2032.

[0044] All technical features in this embodiment can be freely combined according to actual needs.

[0045] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
