Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to an aluminum clamp. Background Art

[0002] V-clamp is a connection device for connecting pipes, valves and pipeline accessories with V-shaped flanges.

[0003] The V-type clamps commonly used at present are complicated to operate and inconvenient to disassemble and assemble. Summary of the invention

[0004] The present invention aims at the above problems existing in the prior art and proposes an aluminum clamp which can be easily disassembled and assembled.

[0005] The present invention can be achieved through the following technical solutions:

[0006] An aluminum clamp, comprising:

[0007] The female clamp and the child clamp are hinged at one end and free at the other end; the free ends of the two clamps are closed to form a clamp in a ring structure;

[0008] A buckle assembly, comprising a buckle plate and a linkage rotation assembly, wherein the linkage rotation assembly has a double-shaft structure and is connected to the free end of the female clamp and the buckle plate via the double-shaft structure;

[0009] The buckle plate can form a locking fit with both sides of the clamp, wherein:

[0010] When the clamp is locked, the buckle plate is rotated through the linkage rotation assembly so that the buckle plate forms a locking fit with the outer sides of the sub-clamp and the mother clamp;

[0011] When the clamp is unlocked, the buckle plate is rotated in the opposite direction through the linkage rotation component to release the locking cooperation between the buckle plate and the outer side of the sub-clamp and the mother clamp, thereby unlocking the clamp.

[0012] As a further improvement of the present invention, the two ends of the buckle plate are respectively a first buckle connection portion and a second buckle connection portion, wherein:

[0013] The first buckle portion is buckled with the outer side of the female clamp;

[0014] The second buckling portion is buckled with the outer side of the sub-clamp.

[0015] As a further improvement of the present invention, the second buckling portion is configured as an eccentric wheel structure, and the outer side of the sub-clamp is provided with an arc surface corresponding to the eccentric wheel structure. Through the cooperation between the eccentric wheel structure and the arc surface, additional locking force is provided when the clamp is locked.

[0016] As a further improvement of the present invention, the eccentric wheel structure has a maximum convex portion and a minimum convex portion, and the maximum convex portion and the minimum convex portion are connected by a curved surface transition, wherein:

[0017] When the clamp is completely locked, the largest convex portion is in close contact with the arc surface, and at this time, the maximum locking force is generated between the second buckle portion and the arc surface;

[0018] During the process of unlocking the clamp, the smallest protrusion rotates to a position in contact with or close to the arcuate surface, at which time the contact pressure between the second buckle portion and the arcuate surface is reduced or disappears.

[0019] As a further improvement of the present invention, the linkage rotation assembly includes a fixed shaft, a movable shaft and a connecting rod, wherein:

[0020] The fixed shaft is arranged at the free end of the female clamp, the movable shaft is passed through the second buckle portion, and the fixed shaft and the movable shaft form a double rotating shaft structure;

[0021] The two ends of the connecting rod are connected to the fixed shaft and the movable shaft respectively.

[0022] As a further improvement of the present invention, after the eccentric wheel structure of the second buckling part is buckled with the outer side of the sub-clamp, the buckle plate pulls the mother clamp through the connecting rod until it is tightly attached to the sub-clamp, and then buckles the first buckling part with the outer side of the mother clamp.

[0023] As a further improvement of the present invention, an elastic member is provided on the outer side of the female clamp, and the elastic member is used to provide elastic force when the first buckling portion is buckled.

[0024] As a further improvement of the present invention, free ends of the female clamp and the sub-clamp are respectively provided with empty grooves for accommodating the connecting rod.

[0025] As a further improvement of the present invention, the inner sides of the female clamp and the sub-clamp are provided with mounting grooves, and the inner side walls of the mounting grooves are provided as inclined surfaces and are used for mounting V-shaped flanges.

[0026] As a further improvement of the present invention, when a sealing ring is installed between two V-shaped flanges, after the clamp is locked, the inclined surface of the installation groove squeezes the two V-shaped flanges. At this time, the sealing ring is squeezed and provides an outward elastic force of the V-shaped flange to enhance the locking force between the clamp and the V-shaped flange.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The linkage rotating assembly has two rotation points, allowing the gusset plate to move in a complex trajectory. This design enables the gusset plate to accurately lock with the outer sides of the mother clamp and the child clamp when locked, thereby ensuring that the clamp remains stable when bearing loads. At the same time, the design of double rotation points can also improve the flexibility and controllability of the gusset plate movement, making the locking and unlocking process smoother and more effective, achieving the purpose of rapid disassembly and assembly;

[0029] 2. The buckle plate forms a locking fit with the outer sides of the sub-clamp and the mother clamp, so that the outer sides of the mother clamp and the sub-clamp are limited at the same time, which is equivalent to providing double insurance. Even under high load or vibration environment, the clamp can be firmly connected to prevent accidental loosening;

[0030] 3. An elastic member is arranged on the outer side of the female clamp, which is used to provide elastic force when the first fastening part is fastened, ensuring close contact between the buckle plate and the female clamp when the clamp is locked, enhancing the stability and reliability of locking. The elastic member can also automatically compensate for the small gap that may exist between the buckle plate and the outer side of the female clamp, and maintain a good locking effect even in the case of slight vibration or temperature change;

[0031] 4. The second buckle part is set as an eccentric wheel structure, and the outer side of the sub-clamp is set as an arc surface corresponding to the eccentric wheel structure. On the one hand, it can generate additional locking force when the clamp is locked to ensure that the clamp remains stable under high load conditions. On the other hand, when unlocking, the smallest convex part rotates to a position in contact with or close to the arc surface, reducing or eliminating the contact pressure between the second buckle part and the arc surface, reducing the unlocking resistance, and making the unlocking process smoother;

[0032] 5. The gasket and the mounting groove of the clamp are matched through the inclined surface. When the clamp is locked, the outward elastic force provided by the sealing ring causes the contact surface between the sub-clamp and the mother clamp to be subjected to additional pressure. This preload force further enhances the locking fit between the buckle plate and the outside of the clamp, ensuring the stability and firmness of the entire clamp system.

[0041] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0042] like Figure 1-6 As shown, the present invention provides an aluminum clamp, comprising:

[0043] The female clamp 110 and the sub-clamp 120 are hinged at one end and free at the other end; the free ends of the two clamps are combined to form a clamp 100 in a ring structure;

[0044] The buckle assembly 200 includes a buckle plate 210 and a linkage rotation assembly 220. The linkage rotation assembly 220 has a double-shaft structure and is connected to the free end of the female clamp 110 and the buckle plate 210 through the double-shaft structure;

[0045] The buckle plate 210 can form a locking fit with both sides of the clamp, wherein:

[0046] When the clamp 100 is locked, the buckle plate 210 is rotated through the linkage rotating assembly 220, so that the buckle plate 210 forms a locking fit with the outer sides of the sub-clamp 120 and the female clamp 110;

[0047] When the clamp 100 is unlocked, the buckle plate 210 performs reverse relative movement through the linkage rotation assembly 220 to release the locking cooperation between the buckle plate 210 and the outer sides of the sub-clamp 120 and the mother clamp 110 , thereby unlocking the clamp 100 .

[0048] It is worth mentioning that the aluminum clamp 100 provided in this embodiment can ensure a good locking effect of the clamp 100 mainly due to the following key design features:

[0049] 1. Double shaft design of the linked rotating assembly 220

[0050] The linkage rotating assembly 220 has a double rotating shaft, allowing the buckle plate 210 to move in a complex trajectory. This design enables the buckle plate 210 to accurately form a locking fit with the outer sides of the mother clamp 110 and the child clamp 120 when locked, thereby ensuring that the clamp 100 remains stable when bearing a load. At the same time, the design of the double rotating points can also improve the flexibility and controllability of the movement of the buckle plate 210, making the locking and unlocking process smoother and more effective, and achieving the purpose of rapid disassembly and assembly;

[0051] 2. Locking cooperation between the buckle plate 210 and the two sides of the clamp 100

[0052] The buckle plate 210 forms a locking fit with the outer sides of the sub-clamp 120 and the female clamp 110, so that the outer sides of the female clamp 110 and the sub-clamp 120 are limited at the same time. This direct physical contact not only enhances the locking force of the clamp 100, but also reduces the potential risk of sliding or loosening.

[0053] Preferably, the two ends of the buckle plate 210 are respectively a first buckle portion 211 and a second buckle portion 212 , the first buckle portion 211 is buckled with the outer side of the mother clamp 110 , and the second buckle portion 212 is buckled with the outer side of the child clamp 120 .

[0054] Preferably, the second buckle portion 212 is configured as an eccentric wheel structure, and the outer side of the sub-clamp 120 is provided with an arc surface 121 corresponding to the eccentric wheel structure, and the locking and unlocking between the buckle plate 210 and the sub-clamp 120 are realized through the cooperation between the eccentric wheel structure and the arc surface 121.

[0055] Specifically, the eccentric wheel structure has a maximum convex portion 2121 and a minimum convex portion 2122, and the maximum convex portion 2121 and the minimum convex portion 2122 are connected by a curved surface transition, wherein:

[0056] When the clamp 100 is completely locked, the largest convex portion 2121 is in close contact with the arc surface 121, and at this time, the maximum locking force is generated between the second buckle portion 212 and the arc surface 121;

[0057] During the unlocking process of the clamp 100 , the smallest protrusion 2122 rotates to a position in contact with or close to the arc surface 121 , and at this time, the contact pressure between the second buckle portion 212 and the arc surface 121 is reduced or disappears.

[0058] Among them, the advantages of the eccentric wheel structure are at least:

[0059] 1. Enhanced locking force: When the clamp is fully locked, the largest convex part of the eccentric wheel structure is in close contact with the arc surface, which increases the locking force and ensures the stability of the clamp under high load conditions;

[0060] 2. Reduce unlocking resistance: When unlocking, the smallest convex part rotates to a position in contact with or close to the arc surface, which reduces or eliminates the contact pressure between the second buckle part and the arc surface, thereby reducing the unlocking resistance;

[0061] 3. Simplified operation: The design of the eccentric wheel structure makes the unlocking process smoother.

[0062] In summary, the buckle assembly provided in this embodiment achieves high stability and locking force of the clamp 100 when locked through the cooperation of the first buckle part 211 and the elastic member 111, and the cooperation of the eccentric wheel structure of the second buckle part 212 and the arc surface 121. This design ensures that when the clamp 100 is locked, the eccentric wheel structure of the second buckle part 212 will not accidentally detach from the arc surface 121, while ensuring the simplicity and smoothness of operation when unlocking, which is particularly suitable for applications requiring quick disassembly and assembly.

[0063] Preferably, the linked rotating assembly 220 includes a fixed shaft 221, a movable shaft 222 and a connecting rod 223, wherein the fixed shaft 221 is arranged at the free end of the female clamp 110, and the movable shaft 222 is passed through the second buckle portion 212, and the fixed shaft 221 and the movable shaft 222 form a double rotating shaft structure, and the two ends of the connecting rod 223 are respectively connected to the fixed shaft 221 and the movable shaft 222.

[0064] When the second buckle portion 212 is buckled with the outer side of the sub-clamp 120, the buckle plate 210 will pull the mother clamp 110 to be in close contact with the sub-clamp 120 through the connecting rod 223, and then the first buckle portion 211 is buckled with the outer side of the mother clamp 110;

[0065] During the process of fastening the first fastening portion 211 with the outer side of the female clamp 110, the buckle plate 210 has a rotation process around the movable axis 222. During this process, the eccentric wheel structure of the second fastening portion 212 rotates from the smallest protrusion 2122 to the largest protrusion 2121 and abuts against the arc surface 121 of the sub-clamp 120. The contact pressure between the second fastening portion 212 and the arc surface 121 will gradually increase, so that the connecting rod 223 further tightens the female clamp 110 until the largest protrusion 2121 abuts against the arc surface 121. The tensioning force of the connecting rod 223 on the female clamp 110 also reaches the maximum. At the same time, the first fastening portion 211 and the free end of the female clamp 110 are fastened, so that the locking force of the entire clamp reaches the maximum value.

[0066] In addition, the design of the linkage rotating assembly 220, through the synergistic effect of the fixed shaft 221, the movable shaft 222, the connecting rod 223 and the buckle plate 210, brings at least the following advantages:

[0067] 1. Quick locking and unlocking: Locking can be completed by simply buckling the two sides of the buckle plate 210 with the free ends of the sub-clamp 120 and the mother clamp 110 in turn, and unlocking can be completed vice versa. In addition, due to the locking structure formed by the eccentric wheel structure of the second buckling portion 212 and the arc surface on the outer side of the sub-clamp 120, assembly and disassembly can be completed in a few seconds while ensuring high-quality results.

[0068] 2. Smooth and seamless unlocking process: After the buckle plate 210 and the mother clamp 110 are unlocked, the buckle plate 210 only needs to be rotated around the movable axis to drive the eccentric wheel structure to rotate, so as to automatically unlock the buckle plate 210 and the child clamp 120, thereby improving the smoothness of the unlocking process.

[0069] 3. Double locking mechanism: The locking cooperation between the buckle plate 210 and the two sides of the clamp 100 is equivalent to providing double insurance, which can maintain the firm connection of the clamp 100 even in a high load or vibration environment to prevent accidental loosening.

[0070] Preferably, an elastic member 111 is provided on the outer side of the female clamp 110, and the elastic member 111 is used to provide elastic force when the first buckle portion 211 is buckled, thereby ensuring close contact between the buckle plate 210 and the female clamp 110 when the clamp 100 is in a locked state, thereby enhancing the stability and reliability of the locking;

[0071] In addition, the elastic member 111 can also automatically compensate for the tiny gap that may exist between the buckle plate 210 and the outer side of the female clamp 110, and maintain a good locking effect even in the case of slight vibration or temperature change.

[0072] Preferably, the free ends of the female clamp 110 and the sub-clamp 120 are respectively provided with empty grooves for accommodating the connecting rod 223. The setting of the empty grooves ensures that the connecting rod 223 always rotates within a predetermined track, thereby ensuring that the entire buckle assembly 200 only rotates within a single plane. At the same time, the space at the free end of the clamp 100 is fully utilized to avoid the protrusion of additional components. After the clamp 100 is locked, the overall structure is more compact.

[0073] Preferably, the inner sides of the female clamp 110 and the sub-clamp 120 are provided with a mounting groove 130, and the mounting groove 130 is used to install the V-shaped flange 140, wherein:

[0074] The inner side wall of the mounting groove is configured as an inclined surface 150 , which matches the inclined surface of the V-shaped flange 140 to ensure the stability and reliability of the connection between the V-shaped flange 140 and the mounting groove 130 .

[0075] In addition, when a sealing ring 160 is installed between the two V-shaped flanges 140, after the clamp 100 is locked, the inclined surface 150 of the installation groove 130 squeezes the two V-shaped flanges 140. At this time, the sealing ring 160 is squeezed and provides an outward elastic force for the V-shaped flange 140, so that the contact surface between the sub-clamp 120 and the mother clamp 110 is subjected to additional pressure. This preload force further enhances the locking fit between the buckle plate 210 and the outside of the clamp 100, ensuring the stability and firmness of the entire clamp 100 system, while also improving the sealing performance between the clamp 100 and the V-shaped flange 140.

[0076] To better illustrate the locking / unlocking principle, the locking and unlocking processes are described as follows:

[0077] Locking process:

[0078] 1. Initial state: the clamp 100 is in an unlocked state, and the smallest protrusion 2122 of the eccentric wheel structure is close to but not in contact with the arc surface 121 on the outer side of the sub-clamp 120;

[0079] 2. Locking starts: the second buckle portion 212 of the buckle plate 210 rotates around the first rotation point through the linkage rotation assembly 220, so that the eccentric wheel structure contacts the arc surface 121 on the outer side of the sub-clamp 120;

[0080] 3. Locking is completed: continue to rotate the buckle plate 210 until the largest protrusion 2121 of the eccentric wheel structure is in close contact with the arc surface 121 on the outer side of the sub-clamp 120. At this time, the maximum locking force is generated between the second buckle portion 212 and the arc surface 121.

[0081] Unlocking process:

[0082] 1. Unlocking preparation: first release the lock between the first buckle portion 211 and the outer side of the female clamp 110;

[0083] 2. Unlocking: Rotate the buckle plate 210 to rotate the eccentric wheel structure of the second buckle portion 212, so that the smallest convex portion 2122 gradually approaches the arc surface 121 on the outer side of the sub-clamp 120;

[0084] 3. Unlocking completed: Continue to rotate until the smallest protrusion 2122 is completely aligned with the arc surface 121. At this time, the contact pressure between the second buckle portion 212 and the sub-clamp 120 disappears, thereby easily completing the unlocking action.
