Technical Field

[0001] This utility model relates to the field of ultra-high voltage quick coupling technology, specifically an ultra-high voltage quick coupling with protective function. Background Technology

[0002] Ultra-high pressure quick couplings are fluid connection devices used under extreme pressure conditions. They are widely used in petroleum, chemical, aerospace, hydraulic systems and other fields. Their design must simultaneously meet the core requirements of high pressure sealing, quick insertion and removal and fatigue resistance.

[0003] As disclosed in the patent announcement CN220688381U, an ultra-high voltage quick connector with protective function includes a connector body. An mounting block is fixedly installed on the outer wall of the connector body. A protective plate is provided on one side of the mounting block, a damper is fixedly installed on one side of the mounting block, and an airbag is fixedly installed on one side of the mounting block. A connecting block is fixedly installed on the top of the connector body, and a support plate is fixedly installed on the top of the connecting block. A hinge block is hinged to the top of the support plate, and a fixing plate is fixedly installed on the top of the hinge block. A handle is fixedly installed on the top of the fixing plate. The beneficial effect of this utility model is that by setting up the damper, it absorbs the impact force, making it less likely for the impact force to be directly transmitted to the connector body, thus helping to ensure the safety of the connector body.

[0004] Although the aforementioned patent has protective plates on both sides, the protective plates can only protect the two sides, which is a small protection range and is not conducive to improving the protection range of the quick connector. Utility Model Content

[0005] The purpose of this invention is to provide an ultra-high voltage quick connector with protective function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An ultra-high voltage quick coupling with protective functions, including

[0008] Connector 1 and connector 2, wherein a quick-connect mechanism is provided at one of the opposite ends of connector 1 and connector 2;

[0009] A protective mechanism is provided on the exterior of the opposite sides of the first and second connectors.

[0010] Preferably, the quick connection mechanism includes a fixed sleeve and a plug sleeve fixedly connected to one end of connector one and connector two facing each other. The upper and lower ends of the fixed sleeve are provided with slots. The upper and lower ends of connector two near connector one are fixedly connected with transverse clips. The clips match the slots, and both are provided with bolt holes in the middle.

[0014] Preferably, the distance between the two ends of the two arc-shaped anti-collision plates is greater than the inner diameter of the bolt hole and less than the inner diameter of the slot.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This ultra-high voltage quick connector with protective function forms a multi-angle protective barrier for the connection part through a protective mechanism consisting of two sets of symmetrically arranged arc-shaped anti-collision plates and spring dampers. Its arc-shaped extension structure significantly expands the protective coverage area. Compared with the existing double-sided flat plate protection, it effectively solves the technical defects of multiple protection dead angles and limited protection range.

[0017] 2. This ultra-high voltage quick coupling with protective function achieves accurate axial positioning and high radial stability through a dual structural design of guiding fit between the insert and the fixed sleeve and wedge positioning fit between the clamp and the slot. It effectively solves the technical problem that existing quick couplings are prone to axial movement and radial displacement under high pressure conditions. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A protective ultra-high voltage quick connector includes a connector 1 and a connector 2. Threaded grooves are formed on the inner walls of opposite ends of connectors 1 and 2. A quick-connect mechanism is provided at the facing ends of connectors 1 and 2. The quick-connect mechanism includes a fixing sleeve 3 and a insert sleeve 4 fixedly connected to the facing ends of connectors 1 and 2. The upper and lower ends of the fixing sleeve 3 are provided with slots 5. Horizontal locking heads 6 are fixedly connected to the upper and lower ends of connector 2 near connector 1. The locking heads 6 match the slots 5, and both have bolt holes 7 in their middle. The quick-connect mechanism also includes a locking hole located near the insert sleeve of the fixing sleeve 3. 4. An annular sealing groove 8 at one end, a sealing ring 9 is detachably installed inside the annular sealing groove 8, the first connector 1 is connected to the middle of the fixed sleeve 3, the second connector 2 is connected to the middle of the insert sleeve 4, a protective mechanism is provided on the opposite side of the first connector 1 and the second connector 2, the protective mechanism includes a fixed ring 10 fixedly connected to the outer wall of the opposite side of the first connector 1 and the second connector 2, both ends of the fixed ring 10 are fixedly connected to a transverse spring damper 11, the movable end of the spring damper 11 is fixedly connected to an arc-shaped anti-collision plate 12, the distance between the two ends of the arc-shaped anti-collision plates 12 is greater than the inner diameter of the bolt hole 7 and less than the inner diameter of the slot 5;

[0026] In this embodiment, the dual structural design of the guide engagement between the insert 4 and the fixed sleeve 3 and the wedge-shaped positioning engagement between the clamp head 6 and the groove 5 achieves the technical effect of accurate axial positioning and high radial stability, effectively solving the technical problem that existing quick connectors are prone to axial movement and radial displacement under high pressure conditions.

[0027] The protective mechanism, consisting of two sets of symmetrically arranged arc-shaped anti-collision plates 12 and spring dampers 11, forms a multi-angle protective barrier for the connection parts. Its arc-shaped extension structure significantly expands the protective coverage area. Compared with the existing double-sided flat plate protection, it effectively solves the technical defects of multiple protection dead angles and limited protection range.

[0028] Working principle: When connecting connector 1 and connector 2, align the clamp 6 of connector 2 with the groove 5 of connector 1 and insert it. At the same time, the insert sleeve 4 is inserted into the fixed sleeve 3. The precise fit between the two not only improves radial stability but also achieves axial positioning and circumferential limiting through the tight engagement of the clamp 6 and the groove 5. After the clamp 6 is fully inserted into the groove 5, use a bolt to pass through the aligned bolt hole 7 for tightening, completing the mechanical locking. At this time, the end face of the insert sleeve 4 tightly abuts against the annular sealing groove 8 inside the fixed sleeve 3, causing the sealing ring 9 to undergo uniform compression deformation, forming a reliable high-pressure seal. Simultaneously, the internal channels of connector 1 and connector 2 are connected through the insert sleeve 4. The precise docking with the fixed sleeve 3 achieves complete connection; when subjected to external impact, the impact force first acts on the arc-shaped anti-collision plate 12, which transmits the impact force to the spring damper 11. The spring damper 11 absorbs the impact energy through compression deformation, effectively slowing down the transmission of the impact force to the joint body. The arrangement of the arc-shaped anti-collision plate 12 ensures that it will not interfere with the docking operation of the clamp 6 and the slot 5. At the same time, the design of the distance between the two ends of the arc-shaped anti-collision plate 12 can ensure that the protection range covers the key connection parts without hindering the installation and removal of screws. When disassembly is required, simply loosen the bolts and pull the clamp 6 out of the slot 5 to achieve quick separation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
