Description

Technical Field

[0001] This disclosure relates to the field of machinery, and more particularly to a clamp, especially a clamp having a grooved belt body. Background Technology

[0002] Currently widely used clamp structures generally suffer from design deficiencies, specifically the lack of dedicated groove structures on their annular belts. This structural defect directly leads to significant inconvenience during actual installation: due to the lack of grooves to guide and assist the deformation of the annular belt, operators need to manually apply force to bend the clamp to adjust its shape. However, limited by the clamp's structural strength and rigidity, manual bending is often difficult to achieve, significantly increasing the difficulty of installation, prolonging installation time, and potentially causing unnecessary deformation damage due to excessive force applied by the operator, affecting the clamp's subsequent normal performance. Furthermore, the inconvenience of installation may even reduce overall assembly efficiency, failing to meet the demands for ease and reliability in practical applications. Utility Model Content

[0003] One objective of this disclosure is to overcome the shortcomings of related technologies and to provide a clamp that, by setting a groove with a specific structure, can effectively reduce the difficulty of installation, facilitate the operator's installation of the clamp, improve installation efficiency, and at the same time ensure the normal performance and reliability of the clamp after installation.

[0004] This disclosure provides a clamp, including an annular belt and two mounting brackets; a groove is provided in the lower center of the annular belt, the groove opening from the inner wall of the annular belt towards the outer wall; an interruption in the annular belt is provided at a position opposite to the groove, and the interruption and the groove are approximately located in the diameter direction of the annular belt; the two mounting brackets are respectively provided on both sides of the interruption and are symmetrically distributed; each mounting bracket has a through hole, and the mounting bracket has an L-shaped structure, the bottom surface of the L-shaped structure being adapted to the shape of the corresponding section of the annular belt; the mounting bracket is connected to the annular belt through the bottom surface of the L-shaped structure.

[0005] In a possible implementation, at least one of the two mounting brackets is provided with a reinforcing structure; the reinforcing structure includes two reinforcing ribs and two reinforcing flanges; the two reinforcing ribs are respectively disposed on both sides of the vertical surface of the L-shaped structure; the two reinforcing flanges are respectively disposed on both sides of the bottom surface of the L-shaped structure, and the reinforcing flanges are formed by the corresponding reinforcing ribs extending from the edge of the vertical surface to the edge of the bottom surface and then turning over.

[0006] In a possible implementation, the reinforcing flange occupies at least a portion of the length of the bottom surface.

[0007] In a possible implementation, the reinforcing flange occupies the entire length of the bottom surface.

[0008] In a possible implementation, the reinforcing structure further includes a convex hull; the convex hull is disposed at the center of the transition between the vertical surface and the bottom surface.

[0009] In a possible implementation, the bottom surface of the L-shaped structure is connected to the annular belt by riveting or welding.

[0010] In a possible implementation, the groove can be any one of an inverted trapezoid, a rectangle, or an arc.

[0011] The clamping technology disclosed herein achieves numerous technical effects and brings corresponding technical benefits: by setting a groove from the inner wall to the outer wall in the lower middle part of the annular belt, and placing the discontinuity of the annular belt at a position opposite to the groove and approximately in the diameter direction, it helps to provide deformation guidance for the annular belt during installation, reducing the difficulty of applying force during manual operation, thereby creating conditions for improving installation convenience; the mounting bracket adopts an L-shaped structure, the bottom surface of which is adapted to the shape of the corresponding section of the annular belt, and the connection with the annular belt is achieved through the bottom surface, which can enhance the fit between the mounting bracket and the annular belt, providing support to ensure the stability of the connection between the two; by setting at least one mounting bracket The reinforced structure includes reinforcing ribs and reinforcing flanges, with the reinforcing flanges formed by extending the reinforcing ribs to the bottom edge and then turning over. This enhances the structural strength of the mounting frame. The design of the reinforcing flange occupying at least a portion or even the entire length of the bottom surface allows for flexible adjustment of the reinforcement effect according to actual needs. The reinforcing structure design with a convex bulge in the center at the transition between the vertical surface and the bottom surface further improves the structural stability of the transition area of ​​the mounting frame. The mounting frame and the annular belt are connected by riveting or welding, and the grooves are designed with inverted trapezoidal, rectangular, or arc shapes, which can adapt to different production process requirements and usage scenarios, providing more flexibility for the production and practical application of clamps.

Detailed Implementation

[0029] The following descriptions of exemplary embodiments are with reference to the accompanying drawings. These exemplary embodiments are merely specific implementations of this disclosure and are not intended to limit the scope of this disclosure in any way. Directional terms used in this disclosure, such as [up], [down], [front], [back], [left], [right], [inner], [outer], [end], etc., refer only to directions referenced to the accompanying drawings. Therefore, the directional terms used are for illustration and understanding of this disclosure and not for limiting it. In the drawings, structurally similar units are denoted by the same reference numerals. In the drawings, for clarity and ease of description, the dimensions of some components have been exaggerated and / or the structures of some components simplified. That is, the dimensions and structures of each component shown in the drawings are schematic and are not intended to limit the scope of this disclosure.

[0030] In the practical application of clamps, the clamp products in related technologies have obvious design flaws, namely the lack of a dedicated groove structure on their annular belt body. This defect directly leads to many problems at the installation and operation level: due to the lack of grooves to guide and assist the deformation of the annular belt body, operators need to manually bend the clamp to adjust its shape, but due to the limitations of the clamp's own structural strength and rigidity, manual bending is often difficult to achieve. This not only significantly increases the installation difficulty and prolongs the operation time, but may also cause clamp deformation and damage due to excessive force, affecting subsequent performance and even reducing overall assembly efficiency. Therefore, how to solve the problems of poor installation convenience, susceptibility to damage, and low assembly efficiency of clamps has become an urgent technical problem that needs to be solved.

[0031] To overcome the shortcomings of the aforementioned related technologies, this disclosure proposes a clamp technology solution, which includes an annular belt and two mounting brackets. The annular belt has a groove extending from the inner wall to the outer wall in its lower center, with the discontinuity located opposite the groove and approximately in the diametrical direction. The two mounting brackets are symmetrically distributed on both sides of the discontinuity, each having a through hole and an L-shaped structure. The bottom surface of the L-shaped structure is adapted to the shape of the corresponding section of the annular belt, and the brackets are connected to the annular belt through this bottom surface.

[0032] The clamp technology disclosed herein offers significant technical effects and benefits: by setting grooves with a specific structure on the annular belt, it effectively guides the deformation of the annular belt, greatly reducing the difficulty for operators to manually adjust the clamps, thereby improving installation convenience and work efficiency; at the same time, it avoids clamp deformation damage caused by excessive force, ensuring the normal performance and reliability of the clamp after installation. Furthermore, the adaptable connection design between the L-shaped mounting bracket and the annular belt further enhances the stability of the overall clamp structure, providing support for its long-term reliable use.

[0033] The technical solution of this disclosure will be described in detail below with reference to the accompanying drawings. The same or similar reference numerals in the drawings correspond to the same or similar components, which are intended to more clearly present the connection relationship and functional characteristics of each structure.

[0034] refer to Figures 1 to 12 The clamp 100 disclosed herein mainly includes an annular belt body 1 and two mounting brackets 2. The "annular belt body 1" refers to a belt-like structure with an annular outline, used for fitting and fixing components (such as pipes, fittings, joints, etc.) to be fastened. It can be made of metal (such as stainless steel, carbon steel, etc.) to ensure sufficient structural strength and rigidity. A groove 4 is provided in the lower center of the annular belt body 1. This groove 4 opens from the inner wall of the annular belt body 1 towards the outer wall, that is, the opening end of the groove 4 is located on the inner wall of the annular belt body 1, and the bottom of the groove faces the outer wall of the annular belt body 1. An interruption 5 of the annular belt body 1 is provided at a position opposite to the groove 4, and the interruption 5 and the groove 4 are approximately located in the diameter direction of the annular belt body 1. The "interruption 5" refers to the not fully closed gap area of ​​the annular belt body 1. The inner diameter of the annular belt body 1 can be adjusted through this interruption 5 to accommodate components of different specifications to be fastened. Two mounting brackets 2 are respectively set on both sides of the discontinuity 5 and are symmetrically distributed. Each mounting bracket 2 has a through hole 6 for passing through bolts and other fasteners. The mounting bracket 2 has an overall L-shaped structure. The "L-shaped structure" means that the mounting bracket 2 is composed of an interconnected bottom surface 7 and a vertical surface 8, and the bottom surface 7 and the vertical surface 8 form an "L" shape. The bottom surface 7 of the L-shaped structure is adapted to the shape of the corresponding section of the annular belt 1. That is, the curvature, length and other dimensions of the bottom surface 7 match the contour of the corresponding installation position on the annular belt 1, ensuring that the bottom surface 7 can fit tightly against the annular belt 1. The mounting bracket 2 is connected to the annular belt 1 through the bottom surface 7 of the L-shaped structure. This connection method can stably fix the mounting bracket 2 on the annular belt 1, providing reliable support for the subsequent tightening of the clamp 100 with fasteners. At the same time, the overall structural design can ensure that after the clamp 100 is fitted with the parts to be tightened, the force on each part is uniform, avoiding structural damage caused by local stress concentration, and improving the overall stability of the clamp 100.

[0035] In a possible implementation, at least one of the two mounting brackets 2 is provided with a reinforcing structure 3. The "reinforcing structure 3" refers to a structural component used to improve the structural strength of the mounting bracket 2 and prevent the mounting bracket 2 from deforming under stress. The reinforcing structure 3 may include two reinforcing ribs 9 and two reinforcing flanges 10. The two reinforcing ribs 9 are respectively provided on both sides of the vertical surface 8 of the L-shaped structure, that is, extending along the height direction of the vertical surface 8 and located on both sides of the width direction of the vertical surface 8. The two reinforcing flanges 10 are respectively provided on both sides of the bottom surface 7 of the L-shaped structure. The reinforcing flanges 10 are formed by the corresponding reinforcing ribs 9 extending from the edge of the vertical surface 8 to the edge of the bottom surface 7 and then flipping them. For example, the reinforcing ribs 9 can be bent and extended from the side edge of the vertical surface 8 towards the bottom surface 7, and then flipped at a certain angle away from the center of the bottom surface 7 when they reach the side edge of the bottom surface 7, forming a flange structure that fits against the bottom surface 7 or has a certain angle. By setting reinforcing ribs 9 and reinforcing flanges 10, the structural strength of the vertical surface 8 and bottom surface 7 of the mounting bracket 2 can be effectively enhanced. Especially when the mounting bracket 2 bears the tightening force of the fastener through the through hole 6, it can prevent the vertical surface 8 from bending and deforming or the connection between the bottom surface 7 and the annular belt 1 from loosening, thus ensuring the stability and reliability of the clamp tightening process.

[0036] In a possible implementation, the reinforcing flange 10 occupies at least a portion of the length of the bottom surface 7, such as... Figure 6 and Figure 7 As shown. This design allows for flexible adjustment of the coverage area of ​​the reinforcing flange 10 according to the actual stress requirements of the mounting frame 2. While meeting the basic structural strength requirements, it reduces material usage and manufacturing costs. It also facilitates the fit and connection between the bottom surface 7 of the mounting frame 2 and the annular belt 1, avoiding installation interference caused by excessive flange length.

[0037] In a possible implementation, the reinforced flange 10 occupies the entire length of the bottom surface 7. This design maximizes the structural strength of the bottom surface 7, and is particularly suitable for scenarios where the mounting bracket 2 needs to withstand large tightening forces. It can effectively disperse the stress on the bottom surface 7, prevent local deformation or breakage of the bottom surface 7, further improve the stability of the connection between the mounting bracket 2 and the annular belt 1, and extend the service life of the clamp.

[0038] In a possible implementation, the reinforcing structure 3 further includes a protrusion 11, which is located at the center of the transition between the vertical surface 8 and the bottom surface 7. The "transition" refers to the connection point between the vertical surface 8 and the bottom surface 7 in the L-shaped structure, typically a rounded or right-angled area with a certain curvature. The protrusion 11 can be formed into an outwardly protruding arc or square structure at the transition by a stamping process. By setting the protrusion 11 at the center of the transition, the structural strength of the transition area can be enhanced, preventing cracks or deformation due to stress concentration at the transition point when the mounting bracket 2 is under load. Simultaneously, the protrusion 11 also reinforces the connection between the vertical surface 8 and the bottom surface 7, further improving the overall structural stability of the mounting bracket 2 and ensuring that it maintains a good structural form during long-term use.

[0039] In a possible implementation, the bottom surface 7 of the L-shaped structure is connected to the annular belt 1 by either press riveting or welding. "Press riveting" refers to using pressure equipment to press and fix the bottom surface 7 of the mounting bracket 2 to the annular belt 1, forming a tight mechanical connection. This connection method requires no additional welding materials, is simple and efficient, and produces a smooth connection that does not affect the appearance or performance of the annular belt 1. "Welding" refers to connecting the bottom surface 7 to the annular belt 1 through high-temperature fusion, such as arc welding or resistance welding. Welded connections ensure a strong bond and are suitable for applications requiring high connection strength. Both connection methods can be flexibly selected based on the application scenario and production volume of the clamp, ensuring the reliability of the connection between the mounting bracket 2 and the annular belt 1 while improving the flexibility and adaptability of clamp production.

[0040] Although the figure shows two connection points between the bottom surface 7 of the L-shaped structure and the annular belt 1, in practical applications, the number of connection points can be adjusted according to the specifications and dimensions of the annular belt 1, the stress requirements of the mounting frame 2, and the overall structural stability requirements. For example, when the diameter of the annular belt 1 is large or the mounting frame 2 needs to withstand greater forces, the number of connection points can be appropriately increased to improve the strength of the connection; when the annular belt 1 is small and the stress is small, the number of connection points can be reduced to simplify the processing technology, as long as the reliability of the connection between the bottom surface 7 and the annular belt 1 is guaranteed and the performance requirements of the clamp are met.

[0041] In a possible implementation, the groove 4 is shaped like an inverted trapezoid (e.g., Figure 9 and Figure 10 As shown), rectangle (as shown) Figure 11 (as shown) or arc-shaped (such as) Figure 12Any one of the following (as shown). For example, an "inverted trapezoidal" groove 4 refers to a groove 4 with a trapezoidal cross-section, where the length of the upper base (the side closest to the inner wall of the annular belt 1) is greater than the length of the lower base (the side closest to the outer wall of the annular belt 1); a "rectangular" groove 4 refers to a groove with a rectangular or square cross-section, where the groove width is the same at the inner and outer walls; and a "circular arc" groove 4 refers to a groove with a semi-circular or arc-shaped cross-section and a smooth curved groove wall. Different shapes of grooves 4 can adapt to different installation and operation requirements. For example, an inverted trapezoidal groove 4 facilitates the deformation of the annular belt 1 during installation, a rectangular groove 4 has a simple processing technology, and a circular arc groove 4 can avoid stress concentration at the groove opening. Users can choose the appropriate groove 4 shape according to the actual installation scenario and processing conditions to improve the adaptability and processing convenience of the clamp.

[0042] In the preferred design of the clamp disclosed herein, the annular belt 1 is preferably made of the same material, specifically 3-series or 4-series stainless steel, such as 304 stainless steel, 409 stainless steel, etc. Compared to the design of some clamps using two layers of materials in related technologies, the single-material design of the annular belt 1 in this disclosure has several advantages: First, the use of the same material ensures the consistency of the overall mechanical properties of the annular belt 1, avoiding uneven local stress caused by differences in strength and toughness between the two materials when the annular belt 1 is subjected to deformation, thereby reducing the risk of structural damage such as cracking and breakage, and improving the overall structural stability of the clamp; Second, the single-material annular belt 1 eliminates the need for additional processes such as bonding and fixing of the two materials during processing, simplifying the production process, shortening the manufacturing cycle, and reducing the scrap rate caused by improper adaptation of multiple materials, thus lowering production costs; Third, from a long-term use perspective, the annular belt 1 made of the same material exhibits more uniform performance in terms of corrosion resistance and aging resistance, avoiding delamination and detachment of the two materials due to differences in electrochemical corrosion or aging rates, extending the service life of the clamp, and is especially suitable for complex operating environments such as humid and corrosive environments.

[0043] In another preferred design of the clamp disclosed herein, considering the force transmission characteristics during the actual tightening process, the force borne by the mounting bracket 2 on the nut side along the bolt axial direction is greater than that borne by the mounting bracket 2 on the bolt head side. When the bolt passes through the through holes 6 of the two mounting brackets 2 and is tightened with the nut, the contact surface between the nut and the corresponding mounting bracket 2 will generate a greater compressive force due to the axial tension of the bolt, and the mounting bracket 2 must withstand the reaction force generated during tightening. The mounting bracket 2 on the bolt head side mainly bears the pressure of the bolt head, and the force is relatively smaller. Based on this difference in force, the two mounting brackets 2 can adopt differentiated structural designs—the mounting bracket 2 on the nut side can be equipped with a reinforcing structure 3 (including reinforcing ribs 9, reinforcing flanges 10, and optional protrusions 11). The reinforcing structure 3 enhances the structural strength of the mounting bracket 2, ensuring that it is not prone to bending, deformation, or loosening when subjected to large axial forces, thus ensuring the reliability of the clamp tightening process; while the mounting bracket 2 on the bolt head side can adopt a design without the reinforcing structure 3 (e.g., Figure 8 As shown in the figure, under the premise of meeting its stress requirements, the processing steps and material usage of structures such as reinforcing ribs 9 and reinforcing flanges 10 are reduced, the production process of mounting bracket 2 is simplified, the overall manufacturing cost of clamp is further reduced, and a compromise between structural performance and cost control is achieved.
