Description

Technical Field

[0001] This utility model relates to the field of quick-change device technology, specifically to a rotary rigid locking quick-connect interface. Background Technology

[0002] In today's society, various construction machinery is becoming increasingly modular. In order to adapt to the construction needs of high turnover, high load, short cycle and changing working conditions, various construction machinery generally adopts the modular solution of "back-end general carrier + front-end functional module". The back-end general carrier is such as tracked or wheeled trailers, skid steer loaders, forklifts and other general power platforms; the front-end functional modules are such as concrete pump buckets, vibratory leveling buckets, roadbed treatment buckets, sweepers, hydraulic breakers and other interchangeable functional components. This requires a modular connector to enable the back-end carrier and front-end modular functional components of the construction machinery to achieve quick and reliable docking.

[0003] In existing technologies, the docking between the back-end general carrier and the front-end functional module is mostly done by hooks, buckles, and threads. Such docking mechanisms usually require the elastic deformation of metal during insertion and unlocking, which cannot cope with high-load and high-vibration modules (such as various drill bits, long-arm tools, and trailers on complex slopes). On the other hand, vibration-resistant locking mechanisms require tools or are slow to install and remove, making it difficult to cope with working conditions that require frequent replacement of the front-end module, resulting in a decrease in overall efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a rotary rigid locking quick-connect interface to solve the problems mentioned in the background section above.

[0005] This utility model is achieved through the following technical solution: A rotary rigid locking quick-connect interface includes a first docking member, a connecting component, and a second docking member connected in sequence. The first docking member is provided with a locking head. The second docking member is provided with a clearance groove for the locking head to pass through. The clearance groove is adapted to the outer contour of the locking head and is used to prevent the first docking member and the second docking member from rotating. The connecting component is provided with a locking groove for the locking head to pass through. The lower end of the connecting component forms a locking surface. The locking head passes through the clearance groove and the locking groove in sequence. By rotating the connecting component, the locking groove is misaligned with the locking head, and the locking surface abuts against the rear end of the locking head.

[0006] Furthermore, the locking head is provided with a plurality of protruding locking lugs, and the shapes of the clearance groove and the locking groove are adapted to the locking head.

[0007] Furthermore, the connecting assembly includes a rotating seat and a first retaining ring fixedly embedded in the rotating seat. The lower end face of the first retaining ring forms the locking surface. The first retaining ring includes a first groove that adapts to the outer contour of the locking head. The rotating seat is provided with a second groove for the locking head to rotate. The first groove and the second groove form the locking groove.

[0008] Furthermore, the connecting assembly also includes a damping ring rotatably sleeved on the lower outer periphery of the rotating seat, a second retaining ring fixed in the damping ring, the second retaining ring including a third groove adapted to the outer contour of the locking head, the rotating seat having a first mark, the damping ring having a second mark, and the second mating member having a third mark.

[0009] Furthermore, the outer contour of the damping ring is polygonal.

[0010] Furthermore, the rotating seat is annular in shape, and its inner wall is formed with a partition strip, thereby forming the second groove. The side of the partition strip is flush with the side of the first groove.

[0011] Furthermore, the outer periphery of the rotating seat is formed with anti-slip stripes.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Reference Figures 1 to 4 As shown, a rotary rigid locking quick-connect interface includes a first docking member 1, a connecting component 2, and a second docking member 3 connected in sequence. The first docking member 1 is provided with a locking head 11; the second docking member 3 is provided with a clearance groove 31 for the locking head 11 to pass through. The clearance groove 31 is adapted to the outer contour of the locking head 11 and is used to prevent the first docking member 1 and the second docking member 3 from rotating; the connecting component 2 is provided with a locking groove 21 for the locking head 11 to pass through. The lower end of the locking groove 21 forms a locking surface 22. The locking head 11 passes through the clearance groove 31 and the locking groove 21 in sequence. By rotating the connecting component 2, the locking groove 21 is misaligned with the locking head 11, and the locking surface 22 abuts against the rear end of the locking head 11.

[0020] Specifically, the first docking member 1 has a first foot plate 13 on the side away from the locking head 11. The first foot plate 13 has multiple bolt holes, through which bolts are passed to lock the first docking member 1 to the rear front-end functional module. Alternatively, the first foot plate 13 can be welded to the rear front-end functional module to prevent loosening due to periodic vibration. Similarly, the second docking member 3 has a second foot plate 33 with multiple bolt holes, which is connected to the front-end functional module.

[0021] When the first docking member 1 and the second docking member 3 need to be docked, the locking head 11 of the first docking member 1 is fed into the relief groove 31 and the locking groove 21. Since the relief groove 31 is adapted to the outer contour of the locking head 11, the mutual engagement of the relief groove 31 and the locking head 11 prevents the first docking member 1 and the second docking member 3 from rotating. Then, by rotating the connecting assembly 2, the relief groove 31 and the locking groove 21 are misaligned and tightly abut against the rear end of the locking head 11 through the locking surface 22. Even if the vibration of the front-end functional module is transmitted to this position, the relief groove 31 and the locking head 11 restrict the left-right movement, and the locking surface 22 and the locking head 11 restrict the front-back movement, thereby preventing the first docking member 1 and the second docking member 3 from separating due to internal and external stress or even periodic vibration.

[0022] With the above structure, the connection or disassembly of the first docking part 1 and the second docking part 3 can be completed without the use of tools, and after connection, no internal or external stress or even periodic vibration in any direction can shake the docking mechanism.

[0023] The locking head 11 is provided with a plurality of protruding locking lugs 12, thereby allowing the locking surface 22 to abut against the rear end of the locking lug 12, and when the relief groove 31 is adapted to the outer contour of the locking head 11, the two cannot rotate relative to each other. Preferably, the locking lugs 12 are symmetrically arranged on both sides of the locking head 11 to ensure force balance.

[0024] Furthermore, the connecting component 2 includes a rotating seat 23 and a first retaining ring 24 fixedly embedded in the rotating seat 23. The lower end face of the first retaining ring 24 forms the locking surface 22. The first retaining ring 24 includes a first groove 241 adapted to the outer contour of the locking head 11. The rotating seat 23 is provided with a second groove 231 for the locking head 11 to rotate. The first groove 241 and the second groove 231 form the locking groove 21.

[0025] The rotating seat 23 and the first retaining ring 24 can be connected by welding or other methods, or they can be integrally formed. During the rotation of the rotating seat 23, the first retaining ring 24 is rotated synchronously. By rotating the first retaining ring 24, the first groove 241 and the clearance groove 31 are misaligned, so that the locking surface 22 formed by the lower end face of the first retaining ring 24 abuts against the rear end of the locking head 11.

[0026] Furthermore, the connecting assembly 2 also includes a damping ring 25 rotatably sleeved on the lower outer periphery of the rotating seat 23. A second retaining ring 26 is fixed in the damping ring 25. The second retaining ring 26 includes a third groove 261 that adapts to the outer contour of the locking head 11. The rotating seat 23 is provided with a first mark 232, the damping ring 25 is provided with a second mark 251, and the second docking member 3 is provided with a third mark 32.

[0027] The first mark 232, the second mark 251, and the third mark 32 can be in the form of grooves, arrows, or round holes. During assembly, the first groove 241 and the third groove 261 are aligned by rotating the rotating base 23. Then, the locking head 11 is inserted into the third groove 261 to align the second mark 251 and the third mark 32. At this time, the third groove 261 is aligned with the clearance groove 31. By continuing to move the first docking member 1, the locking head 11 is inserted into the clearance groove 31. Then, by rotating the rotating base 23, when the first mark 232 and the second mark 251 are aligned, the first groove 241 and the third groove 261 are arranged perpendicularly, thereby causing the first groove 241 to be misaligned with the clearance groove 31. At this time, the locking surface 22 abuts against the rear end of the locking head 11 to complete the locking connection between the first docking member 1 and the second docking member 3.

[0028] The first mark 232 consists of mark 2321 surrounding the outer circumference of the rotating seat 23 and mark 2322 located at the end of mark 2321 and forming a circular groove. When the second mark 251 points to the end of mark 2321, it is the unlocked position of the first docking member 1 and the second docking member 3. When the second mark 251 points to mark 2322, it is the locked position of the first docking member 1 and the second docking member 3.

[0029] The outer contour of the damping ring 25 is polygonal, which makes it easy to distinguish the damping ring 25 from the rotating seat 23. During assembly, the damping ring 25 and the rotating seat 23 are held by both hands respectively, and the connecting component 2 is switched between the unlocked and locked positions by keeping the damping ring 25 stationary and rotating only the rotating seat 23.

[0030] The rotating seat 23 is annular, with a spacer 233 forming its inner wall, thus constituting the second groove 231. The side of the spacer 233 is flush with the side of the first groove 241. The spacer 233 and the side of the first groove 241 are flush, making the inner wall of the rotating seat 23 a coplanar reference. With the spacer 233 in place, when the locking head 11 is inserted into the rotating seat 23, the spacer 233 rotates at the angle formed by the two locking lugs 12, preventing the rotating seat 23 from over-rotating or spinning freely, and significantly improving the reliability of blind operation.

[0031] The outer periphery of the rotating seat 23 is provided with anti-slip stripes 234, which facilitate the operation of the rotating seat 23.
