Description

Technical Field

[0001] This utility model relates to a clamp, and more specifically to a flange clamp assembly. Background Technology

[0002] A flange clamping assembly is a specialized fixture used during flange processing. During flange processing, the flange is first placed in the lower clamp, and then the upper clamp is fitted over the flange. Once the upper and lower clamps are in place, the two clamping assemblies are secured with screws, and then the flange is processed internally. When flanges are the same size but have different thicknesses, different clamping assemblies must be selected according to the flange model. This requires a significant investment in purchasing multiple models of clamping assemblies, making it inconvenient to adjust the internal components of the clamping assemblies for flanges of the same size but different thicknesses during processing.

[0003] Therefore, the existing technology has a utility model patent with patent number 202223132593.6 entitled "A Flange Clamp Assembly for Flange Processing". It discloses that by setting the adjustment mechanism, it can clamp flanges of different thicknesses. However, in the process of clamping the flange, the flange needs to be initially positioned by the lower clamp, and then the upper clamp is closed to complete the clamping. Finally, the clamp is clamped by bolts. However, the above clamping process is very inconvenient, requiring people to tighten the bolts, which is very inconvenient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flange clamping assembly that facilitates the clamping process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flange clamp assembly, including an upper clamping ring and a lower clamping ring, both of which are arc-shaped. Both ends of the upper clamping ring are provided with locking elements, and both ends of the lower clamping ring are provided with fasteners. When the upper and lower clamping rings are closed, the locking elements and fasteners are connected and fixed. A locking pin is fixed to the side of the locking element facing the fastener. A locking hole is provided on the fastener. An elastic locking block is provided on the side of the locking pin. The locking pin passes through the locking hole, and the elastic locking block abuts against the edge of the locking hole.

[0006] As a further improvement of this utility model, the card hole is truncated pyramidal in shape, with the larger diameter end of the card hole facing the carding component, and the smaller diameter end of the hole abutting against the elastic card block.

[0007] As a further improvement of this utility model, the elastic block is an arc-shaped elastic sheet structure, and both ends of the elastic block are fixedly installed on the side wall of the locking post.

[0008] As a further improvement of this utility model, an installation groove is provided on one side of the locking post. The cross-section of the installation groove is barbed. The elastic locking block is an arc-shaped plate structure. Both ends of the elastic locking block are bent with barbs. The shape of the barbs of the elastic locking block is adapted to the installation groove. The barbs slide from the opening of the installation groove into the installation groove to fix the elastic locking block to the side wall of the locking post.

[0009] The beneficial effects of this utility model are as follows: This utility model, through the cooperative design of the locking post and the elastic locking block, eliminates the need for additional bolts. Simply insert the locking post into the locking hole, and the upper and lower clamping rings are quickly fixed by the contact between the elastic locking block and the edge of the locking hole, significantly simplifying the clamping process and saving operation time. The frustum-shaped structure of the locking hole ensures a stable engagement and positioning between the smaller diameter end of the hole and the elastic locking block. During engagement, the inclined sidewall guides the elastic locking block to retract, and after reaching its final position, it releases, achieving the engagement of the clamp and fastener by locking the edge of the locking hole. The elastic locking block adopts an arc-shaped elastic sheet structure, providing sufficient elastic deformation force for rapid insertion and removal while maintaining stable clamping force in the engaged state. Furthermore, the elastic locking block is fixed to the locking post through the cooperation of a barb and a barb-shaped mounting groove, making installation and disassembly convenient, facilitating maintenance and component replacement. The overall structural design is ingenious, effectively solving the problems of inconvenient and inefficient clamping operations in existing technologies, and possessing strong practicality and market application value.

[0011] Figure 2 for Figure 1 Enlarged view of part A in the middle. Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0013] Reference Figure 1 As shown, the flange clamp assembly of this embodiment includes an arc-shaped upper clamping ring 1 and a lower clamping ring 2. The upper clamping ring 1 has clamping elements 3 at both ends, and the lower clamping ring 2 has fasteners 4 at both ends. When closed, the clamping elements 3 and fasteners 4 are connected and fixed. A clamping post 5 is fixed to the side of the clamping element 3 facing the fastener 4. The fastener 4 has a clamping hole 6. An elastic clamping block 7 is provided on the side of the clamping post 5. After the clamping post 5 passes through the clamping hole 6, the elastic clamping block 7 abuts against the edge of the hole 6 to achieve quick fixation. When the upper clamping ring 1 and the lower clamping ring 2 are closed, the clamping post 5 is inserted into the clamping hole 6. The elastic clamping block 7 is elastically deformed by the pressure of the hole edge, passes through the hole edge, and then resets to clamp the hole edge, forming a boltless quick-clamping structure. Compared with the clamping method in the prior art that requires tightening bolts, this structure eliminates the cumbersome bolt operation, allowing clamping to be completed with one hand, significantly improving the convenience and efficiency of flange clamping.

[0014] Furthermore, refer to Figure 1 and Figure 2 As shown, the locking hole 6 is frustum-shaped, with the larger diameter end facing the locking piece 3, and the edge of the smaller diameter end abutting against the elastic locking block 7. The frustum-shaped locking hole 6 forms a guide slope, facilitating the quick alignment and insertion of the locking post 5. At the same time, the edge of the smaller diameter hole limits the elastic locking block 7, preventing the locking post 5 from coming out in the opposite direction. This structural design optimizes the locking force using geometry, making the contraction of the elastic locking block 7 smoother. During assembly, it is only necessary to align the locking post 5 with the locking hole 6 and then push it in straight, solving the problem of time-consuming bolt connection operations in the prior art.

[0015] Furthermore, the elastic block 7 is an arc-shaped elastic sheet structure, with both ends fixedly mounted on the sidewalls of the clamping post 5. The arc-shaped design gives the elastic block 7 excellent elastic deformation capability. When inserted into the clamping hole 6, the arc-shaped elastic sheet is compressed and bends inward, returning to its original position after passing through the hole edge, thus tightly fitting against the edge of the clamping hole 6. The fixed structure at both ends ensures that the elastic block 7 is not easily dislodged during long-term use, providing a stable clamping force. Compared to traditional single-point fixed elastic components, this structure of the elastic block 7 distributes force evenly, has stronger fatigue resistance, can adapt to frequent clamping operations, and improves the durability and reliability of the clamping assembly.

[0016] Furthermore, refer to Figure 2 As shown, the locking post 5 has a mounting groove 51 with a barbed cross-section on one side. The elastic locking block 7 has an arc-shaped sheet structure with barbs at both ends that fit the mounting groove 51. The barbs slide into the mounting groove 51 from the groove opening to achieve fixed installation. This mating structure of barbs and mounting groove 51 makes the installation and removal of the elastic locking block 7 simple and quick, and the component replacement can be completed without the aid of tools. At the same time, the mechanical limit formed by the barb structure ensures that the installation position of the elastic locking block 7 on the locking post 5 is accurate, avoiding the problem of locking failure caused by installation deviation, facilitating later maintenance and component replacement, and further improving the practicality and maintainability of the clamping assembly.

[0017] In summary, this solution constructs a boltless rapid clamping system through the cooperation of the elastic locking block 7 and the frustum-shaped locking hole 6, the arc-shaped elastic sheet structure, and the barbed installation design. Compared with the flange clamps in the background technology that rely on bolt fixation, this component achieves convenient "plug-and-play" operation, eliminating the tedious steps of tightening bolts, and clamping can be completed with one hand, significantly improving work efficiency. At the same time, the multiple limiting structure ensures stable clamping and prevents loosening, solving the problems of inconvenient operation and time-consuming labor in traditional clamps. It has the advantages of simple structure, convenient operation, and reliable clamping, providing an efficient technical solution for rapid positioning and fixing in the flange processing and installation process.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
