Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment accessories technology, and in particular to a variable flange end cover with interchangeable flange sizes. Background Technology

[0002] Flange end caps are a widely used connection and sealing component in mechanical equipment, such as on the housing of motors, reducers, or pumps. Flange end caps are not only used to seal the chambers, but the flanges on them are also used for docking and installation with other external equipment or pipelines.

[0003] In conventional designs, the end cover body of the flange and the flange that it connects to are usually designed as an integral structure. This integral structure has good structural rigidity and sealing performance under certain specifications.

[0004] However, there are many different interface standards for mechanical equipment. Different customers or different application scenarios often require flanges of different sizes, hole spacings or outer diameters. When using the above-mentioned integrated flange end cap structure, manufacturers must develop and produce a variety of complete end cap products of different specifications in order to meet market demand. This design method, which relies on a complete set of molds and finished product inventory, not only leads to an increase in production and warehousing costs and causes serious material backlog, but also results in a long response cycle, poor flexibility, and inability to quickly adapt to various changes in the market when facing customized or small-batch customer needs.

[0005] Therefore, this utility model proposes a variable flange end cap with interchangeable flange sizes to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing flange end caps, such as the large number of product specifications, high inventory costs, and inflexible interface size change due to the integrated design of the flange and end cap body, this utility model aims to provide a variable flange end cap with an improved structure that can effectively solve the above problems and has a replaceable flange size.

[0007] This utility model provides a variable flange end cover with interchangeable flange sizes. To accommodate components of different sizes, the variable flange end cover includes an outer ring, an inner ring, and a fixing rod. The inner ring is located inside the outer ring, and the two ends of the fixing rod are fixedly connected to the inner wall of the outer ring and the outer wall of the inner ring, respectively. These three components together constitute the end cover body.

[0008] The variable flange end cap also includes the fixing plate and the screw. The fixing plate abuts against the end face of the fixing rod, and the screw passes through the fixing plate and is detachably threaded to the outer ring. In this combination, the fixing plate is replaceably fixed to the end cap body.

[0009] Preferably, a fixing ring is fixedly connected to the outer wall of the outer ring. The fixing ring is used to install the entire variable flange end cover to the external equipment. The fixing ring is provided with mounting holes for fixing the end cover to the external equipment to facilitate overall fixation.

[0010] Preferably, a plurality of fixing rods are provided, and the plurality of fixing rods are evenly spaced along the circumference of the outer ring. This evenly distributed structure not only enhances the overall structural rigidity of the end cap body, but also provides a stable and uniform mounting support surface for the fixing piece.

[0011] Preferably, the fixing plate is provided with a through hole for the screw to pass through, and the outer ring is provided with a threaded hole corresponding to the position of the through hole to cooperate with the screw. After the screw passes through the through hole, it is screwed into the threaded hole to achieve reliable thread fastening.

[0012] Preferably, the fixing plate has an annular plate structure, which allows it to be adapted to common pipe or equipment interfaces when used as a flange.

[0013] Preferably, the inner ring defines a central through-hole, which can be used to pass through the motor shaft or allow fluid to pass through.

[0014] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art where the flange end cover is integrally formed with the flange plate, which requires the entire end cover to be replaced when changing specifications, by designing the flange end cover as a separable structure consisting of the end cover body and the fixing plate, and using screws to achieve a detachable connection between the two. This achieves the technical effect of reducing production and inventory costs, reducing material backlog and resource waste.

[0015] 2. This utility model allows users to quickly replace fixing pieces of different sizes as needed, enabling a single end cap body to match multiple interface standards. This solves the problem of limited functionality and poor adaptability of existing end cap products, achieving the technical effect of improving product versatility and flexibly meeting diverse customer needs.

[0018] 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.

[0019] Please refer to Figures 1 to 4 This utility model provides a variable flange end cover with interchangeable flange sizes, which aims to solve the problem in the prior art where the flange end cover and flange are manufactured as a single unit, resulting in the need to replace the entire end cover when changing to different specifications of the interface, thus causing high inventory costs and inflexible adaptation.

[0020] like Figure 1 and Figure 2 As shown, the variable flange end cap with replaceable flange size includes an assembly 1 for adapting to different sizes. The assembly 1 includes an end cap body, which includes an outer ring 101, an inner ring 104 located inside the outer ring 101, and a plurality of fixing rods 103. The plurality of fixing rods 103 are evenly spaced along the circumference of the outer ring 101, and the two ends of the plurality of fixing rods 103 are respectively fixedly connected to the inner wall of the outer ring 101 and the outer wall of the inner ring 104. Through the connection relationship between the outer ring 101, the inner ring 104, and the plurality of fixing rods 103, a stable annular frame for bearing is formed. The inner ring 104 defines a central through hole. For ease of installation, a fixing ring 102 is also fixedly connected to the outer wall of the outer ring 101. The fixing ring 102 is provided with mounting holes for fixing the end cap to external equipment.

[0021] like Figure 1 , Figure 3 and Figure 4As shown, the component 1 adapted to different sizes also includes a fixing plate 105 as a flange and a plurality of screws 106 for fastening. The fixing plate 105 has an annular plate structure. When installed, the fixing plate 105 abuts against the end face of the plurality of fixing rods 103. The fixing plate 105 is provided with a through hole for the screws 106 to pass through. The outer ring 101 is provided with a threaded hole corresponding to the position of the through hole to cooperate with the screws 106. The screws 106 pass through the through holes on the fixing plate 105 in sequence and are detachably threaded to the threaded holes on the outer ring 101. Through this detachable connection method, the fixing plate 105 can be replaced and fixed to the end cap body composed of the outer ring 101, the inner ring 104 and the fixing rods 103.

[0022] The fixing plate 105, serving as a replaceable component of the flange, has an annular plate structure. Multiple through holes for the screws 106 to pass through are provided on the fixing plate 105 along its circumference. The end cap body has positioning and fastening structures that mate with the fixing plate 105. Specifically, the end faces of the multiple fixing rods 103 serve as axial positioning surfaces for the fixing plate 105. The outer ring 101 has multiple threaded holes corresponding to the positions of the through holes on the fixing plate 105, which mate with the screws 106. In the assembled state, the inner plane of the fixing plate 105 and the end faces of the multiple fixing rods 103 are aligned. The abutting relationship ensures the axial positioning accuracy of the fixing piece 105 during installation. At the same time, the multiple screws 106 pass through the through hole of the fixing piece 105 in sequence and are detachably threaded into the threaded hole of the outer ring 101. By tightening the screws 106, the fixing piece 105 is firmly pressed against the end face of the fixing rod 103. This structure, in which the fixing piece 105 is detachably fastened to the outer ring 101 by the screws 106, and the fixing piece 105 abuts against the fixing rod 103, ensures that the fixing piece 105 is securely and reliably installed on the end cap body.

[0023] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to facilitate the installation of the entire component 1, which is adapted to different sizes, onto an external device, please refer to... Figure 1 and Figure 2 A fixing ring 102 is fixedly connected to the outer wall of the outer ring 101, and the fixing ring 102 is provided with mounting holes for fixing the end cap to an external device.

[0024] In another preferred embodiment, in order to enhance the structural rigidity of the end cap body and provide uniform support for the fixing piece 105, a plurality of fixing rods 103 are provided, and the plurality of fixing rods 103 are evenly spaced along the circumference of the outer ring 101.

[0025] In one specific embodiment, the fixing piece 105 has an annular sheet structure, and the inner ring 104 defines a central through hole.

[0026] The working principle of this utility model of a variable flange end cover with interchangeable flange sizes is as follows: When the flange size of the component 1, which is adapted to different sizes, needs to be changed to accommodate different docking requirements, the operator only needs to loosen and unscrew multiple screws 106. Since the screws 106 pass through the fixing plate 105 and are detachably threaded to the outer ring 101, unscrewing the screws 106 releases the fastening connection between the fixing plate 105 and the outer ring 101. At this time, the fixing plate 105, which was originally abutting against the end face of the fixing rod 103, can be easily removed, thereby separating it from the end cap body composed of the outer ring 101, inner ring 104, fixing rod 103 and fixing ring 102.

[0027] When installing the new fixing plate 105, the operator places the new-sized fixing plate 105 on the end cap body, so that its inner plane abuts against the end face of the plurality of fixing rods 103 to achieve axial positioning, and aligns the through hole on the fixing plate 105 with the threaded hole on the outer ring 101. Finally, the plurality of screws 106 are passed through the through hole and screwed into the threaded hole in sequence to tighten them, and the replacement operation can be completed quickly.

[0028] By combining the modular separation design of the fixing piece 105 with the end cap body and the detachable connection using the screw 106, this utility model solves the problems of high cost and poor flexibility caused by the integrated structure of the end cap and flange in the prior art.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
