Description

Technical Field

[0001] The present application relates to the technical field of rotating connection of sheet metal parts, and in particular to a combined hinge and a rotating connection structure. Background Art

[0002] In the manufacturing industry, sheet metal connection is a common process step. The connection between sheet metal parts includes fixed connection or movable connection, and movable connection includes sliding connection and rotating connection. The rotating connection between two existing sheet metal components often uses a hinge structure. The existing connection between hinges and sheet metal generally connects the hinge piece directly to the sheet metal component.

[0003] However, sheet metal components are generally thinner. When rotating the connection, if the hinge is directly connected to the sheet metal, there may be problems such as insufficient strength, inconvenient locking, and limited adjustment at the connection point. Utility Model Content

[0004] The present application aims to solve one of the technical problems in the related art to a certain extent. To this end, the present application provides a combined hinge and a rotating connection structure.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a combined hinge for rotatably connecting two components, a mounting plate connected to the hinge is formed on the component, the hinge includes a reinforcing connector and two rotatably connected hinge pieces, each hinge piece is provided with a reinforcing connector, the reinforcing connector has a mounting surface that fits the mounting plate and is fixedly connected to the mounting plate, the area of ​​the joint surface between the reinforcing connector and the mounting plate is larger than the cross-sectional area of ​​the hinge piece, the hinge piece is fixedly connected to the reinforcing connector along the normal direction of the mounting surface to realize the connection between the hinge piece and the component.

[0006] In this technical solution, a reinforcing connector is provided. During assembly, the reinforcing connector is fixed on the mounting plate of the component to be connected. The connection strength between the hinge and the mounting plate is increased by increasing the thickness of the connection part and the area of ​​the joint part. After the two components are connected by the hinge in this technical solution, the strength of the component at the connection part (mounting plate) is increased, thereby improving the service life of the component. Moreover, by increasing the thickness of the mounting plate, it can withstand a greater locking force, facilitating the connection of the locking member.

[0007] Furthermore, the hinge piece and the reinforcing connector are arranged on both sides of the mounting plate, and the hinge piece and the reinforcing connector are fixedly connected with the mounting plate. In this way, the hinge piece, the reinforcing connector and the mounting on the component are fixed together, and the mounting plate is arranged between the hinge piece and the reinforcing connector, so as to improve the stability and connection strength of the connection between the hinge and the component.

[0008] Furthermore, the strengthening connector is fixed to the mounting plate by welding or screws. Welding can avoid drilling holes on the components, thereby avoiding the reduction of the strength of the components caused by drilling. The combination of welding and screw fixing can increase the scope of application scenarios of the hinge and make it more adaptable.

[0009] Furthermore, the reinforcing connector includes a reinforcing plate and a connecting plate, wherein the reinforcing plate is arranged between the connecting plate and the mounting plate, and one end surface of the reinforcing plate is fitted with the mounting plate to form a mounting surface. The reinforcing plate mainly serves to increase the strength of the component, and the connecting piece is convenient for connecting with the component or hinge piece. The reinforcing plate and the connecting piece are arranged separately for convenient production and easy configuration of different materials to ensure their different characteristics.

[0010] Furthermore, the reinforcing plate is configured as an elastic member, which is convenient for adjustment and can apply a certain pre-tightening force to the locking member in the assembled state, thereby improving the connection strength.

[0011] Furthermore, the reinforcing plate is made of metal or high-strength plastic material, and the connecting plate and the reinforcing plate are fixedly connected. The selection of the reinforcing plate material ensures that it has a certain strength and elasticity, and the connecting plate and the reinforcing plate are fixedly connected to facilitate assembly and avoid disorganization caused by too many parts.

[0012] Furthermore, at least two opposite ends of the connecting plate in at least one direction are provided with limiting plates, and the reinforcing plate is arranged between the limiting plates during assembly, and one end of the limiting plate is inserted into the mounting plate and cooperates with the mounting plate to limit the position of the reinforcing plate, making the assembly structure more stable.

[0013] Furthermore, one end of the limiting piece is provided with a boss protruding from the end face of the limiting piece, and the mounting plate is provided with a socket corresponding to the boss, and the boss is inserted into the socket so that the end face of the limiting piece fits with the end face of the mounting plate. In this way, the plug-in fit between the boss and the socket fixes the position of the connecting plate and the mounting plate (component). During assembly, the locking force of the locking member presses the end face of the limiting piece on the connecting member against the mounting plate, thereby achieving a stable connection between the connecting member and the component.

[0014] Furthermore, the thickness of the reinforcing connector is greater than the thickness of the mounting plate, so as to ensure the strength of the connecting part.

[0015] Furthermore, the hinge piece and the reinforcing connector are fixed by screws.

[0016] In addition, the present application also discloses a rotating connection structure, including a first component and a second component configured as sheet metal parts, the first component is configured as a fixed part or a movable part, and the second component is configured as a movable part, and also includes a combined hinge of any of the above items, the first component and the second component are respectively provided with mounting plates, and the combined hinge rotatably connects the first component and the second component through the mounting plate.

[0017] The reasoning process of the beneficial effects of the rotating connection structure provided in the present application is similar to that of the aforementioned combined hinge, and will not be repeated here.

[0018] These features and advantages of the present application will be disclosed in detail in the following specific embodiments and drawings. The best embodiments or means of the present application will be described in detail in conjunction with the drawings, but they are not intended to limit the technical solutions of the present application. In addition, there are multiple features, elements, and components that appear in each of the following texts and drawings, and different symbols or numbers are marked for convenience, but they all represent components with the same or similar structures or functions.

[0033] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments based on the embodiments are intended to be used to explain the present application and cannot be understood as limiting the present application.

[0034] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present application. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0035] See attached Figure 2 , 3 4. One of the embodiments of the present application discloses a combined hinge for rotatably connecting two components. A mounting plate 5 connected to the hinge is formed on the component. The hinge includes a reinforcing connector 2 and two rotatably connected hinge pieces 1. One end of the two hinge pieces 1 is rotatably connected to the same pin 11, so that both hinge pieces 1 can rotate around the pin 11. After assembly, the rotation axis of the two components is also the pin 11. Each hinge piece 1 is provided with a reinforcing connector 2. The reinforcing connector 2 has a mounting surface that fits the mounting plate 5 and is fixedly connected to the mounting plate 5 to enhance the connection strength of the mounting plate 5. The hinge piece 1 is fixedly connected to the reinforcing connector 2 along the normal direction of the mounting surface to achieve the connection between the hinge piece 1 and the component. The area where the reinforcing connector 2 fits the mounting plate 5 is larger than the cross-sectional area of ​​the hinge piece 1. Compared with directly connecting the hinge piece 1 to the component, the provision of the reinforcing connector 2 increases the area of ​​the connection, thereby improving the stability and strength of the connection.

[0036] In actual setting, a plurality of connection holes 12 are provided on the hinge piece 1 for connection with the component or the reinforcing connector 2. In order to prevent the nut end of the screw used for connection from protruding from the end surface of the hinge piece 1, the connection hole 12 can be set as a countersunk hole style.

[0037] In this embodiment, a reinforcing connector 2 is provided. During assembly, the reinforcing connector 2 is fixed on the mounting plate 5 of the component to be connected. One end face of the reinforcing connector 2 is arranged in close contact with one end face of the mounting plate 5 to form a mounting surface. During actual setting, the contact area between the reinforcing connector 2 and the mounting plate 5 is as large as possible within the range allowed by the space, so as to increase the strength of the connection part. The design of the reinforcing connector 2 is equivalent to increasing the thickness of the connection part (the thickness of the sheet metal part is generally thinner) and the contact area of ​​the connection part, thereby increasing the connection strength of the mounting plate 5 and improving the service life of the component. Moreover, by increasing the thickness of the mounting plate 5, it can withstand a greater locking force, which also facilitates the connection of the locking member.

[0038] The connection between the hinge piece 1 and the component in this embodiment has the following two forms: first, see the attached Figure 3 , 5 The hinge piece 1 is directly connected to the reinforcing connector 2, and the reinforcing connector 2 is connected to the mounting plate 5 on the component, that is, the hinge piece 1 and the component are not directly connected, which can adapt to the application scenarios where it is inconvenient to drill holes on the component or avoidance design is required due to installation relationship; second, refer to the attached Figure 4 , 6 The hinge piece 1 and the reinforcing connector 2 are arranged on both sides of the mounting plate 5, and the hinge piece 1 and the reinforcing connector are fixedly connected with the mounting plate 5, so that the hinge piece 1, the reinforcing connector and the installation on the component are fixed together, and the mounting plate 5 is clamped between the hinge piece 1 and the reinforcing connector. At this time, the locking piece improves the stability and connection strength of the connection between the hinge and the component.

[0039] The reinforcing connector 2 in this embodiment is welded or screwed to the mounting plate 5. Welding can avoid drilling holes on the component and avoid the reduction of the strength of the component caused by drilling. The combination of welding and screwing can increase the range of application scenarios of the hinge and make it more adaptable.

[0040] The reinforcing connector 2 of this embodiment includes a reinforcing plate 21 and a connecting plate 22. When assembled, the reinforcing plate 21 is arranged between the connecting plate 22 and the mounting plate 5, and one end surface of the reinforcing plate 21 is fitted with the mounting plate 5 to form a mounting surface. The reinforcing plate 21 is in direct contact with the component. In actual design, the shape of the reinforcing plate 21 can be adapted according to the shape of the mounting plate 5 on the component to ensure a better contact effect between the two. In addition, a groove, a depression, a hole or other structures can be set on the end surface where the reinforcing plate 21 and the mounting plate 5 are fitted to each other to ensure the fitting effect between the two and avoid the problem that the two planes cannot be fully contacted due to the problem of flatness. The reinforcing plate 21 mainly serves to increase the strength of the component.

[0041] The connector is used to connect with the component or hinge 1. As can be seen from the above content, the connector can be directly connected with the hinge 1, or it can be connected with the mounting plate 5 and the hinge 1. Since the reinforcing plate 21 and the connecting plate 22 have different functions, that is, their production materials or processes are different, the reinforcing plate 21 and the connector are set separately to facilitate production and manufacturing and to configure different materials to ensure their different characteristics. Of course, the two can also be set as an integrated structure.

[0042] As one of the optional embodiments of the present invention, the reinforcing plate 21 of the present invention is set as an elastic member. The elastic characteristics of the reinforcing plate 21 can be reflected by its material, such as the reinforcing plate 21 is made of elastic material. The elastic characteristics of the reinforcing plate 21 can also be reflected by the structure of the reinforcing plate 21, such as the structure of the reinforcing plate 21 is set to a bending form (V-shaped, U-shaped, X-shaped or other similar shapes), so that when the reinforcing plate 21 is subjected to locking pressure, the reinforcing plate 21 will produce a certain elastic deformation, and apply a certain pre-tightening force to the locking member, thereby improving the connection strength.

[0043] Of course, it is conceivable that the reinforcing plate 21 in this embodiment can be made of metal or high-strength plastic material to ensure that it has a certain strength and elasticity; in addition, in actual settings, the connecting plate 22 and the reinforcing plate 21 can be set to be fixedly connected, and the fixed connection between the two can be in the form of welding or screw connection, which makes the integrity better, reduces the number of components of the combined hinge, and avoids the problem of easy loss of multiple components.

[0044] See attached Figure 4 , 7 In one embodiment of the utility model, the connecting plate 22 is configured to be provided with limiting pieces 23 at two opposite ends in at least one direction. In the figure, limiting pieces 23 are designed at two ends of one direction of the connecting plate 22, so that the reinforcing plate 21 is arranged between the limiting pieces 23 during assembly, and one end of the limiting piece 23 is inserted into the mounting plate 5 and cooperates with the mounting plate 5 to limit the position of the reinforcing plate 21.

[0045] In this embodiment, a boss 24 is further arranged at one end of the limiting piece 23, protruding from the end face of the limiting piece 23, and the mounting plate 5 is provided with a socket corresponding to the boss 24. The boss 24 is inserted into the socket so that the end face of the limiting piece 23 fits with the end face of the mounting plate 5. In this way, the plug-in fit between the boss 24 and the socket fixes the position of the connecting plate 22 and the mounting plate 5 (component). During assembly, the locking force of the locking member presses the end face of the limiting piece 23 on the connecting member against the mounting plate 5, thereby realizing a stable connection between the connecting member and the component.

[0046] It is conceivable that the connection plate 22 in this embodiment may further be provided with limiting pieces 23 in two opposite directions, so that the reinforcing plate 21 may be limited in multiple directions to make it more stable.

[0047] As an optional implementation, see the attached Figure 3 In this embodiment, the connecting plate 22 can also be provided with a support plate 25. When in use, the support plate 25 can be supported on the component, which can further improve the strength of the connecting part. Of course, in actual settings, the structure of the reinforcing connecting member 2 provided on the two hinge pieces 1 can adopt the same structure or different structures. See the attached Figure 5 .

[0048] The thickness of the reinforcing connector 2 in the present invention is greater than the thickness of the mounting plate 5. Since the thickness of the sheet metal component is relatively thin, that is, the thickness of the mounting plate 5 may be relatively thin, the thickness of the reinforcing connector 2 is designed to ensure the strength of the connection part. It can be imagined that when the reinforcing connector 2 includes a reinforcing plate 21 and a connector, the thickness of the reinforcing plate 21 should be set to be not less than the thickness of the mounting plate 5, otherwise the reinforcing effect may not be achieved.

[0049] The hinge piece 1 and the reinforcing connecting member 2 in the utility model are fixed by screws, which is convenient for disassembly and installation. Since the hinge piece 1 and the reinforcing connecting member 2 may be distributed on both sides of the mounting plate 5, screws are used to conveniently pass through the mounting plate 5 to connect the two.

[0050] See attached Figure 1 In addition, the present application also discloses a rotating connection structure, including a first member 3 and a second member 4 set as sheet metal parts, the first member 3 is set as a fixed part or a movable part, and the second member 4 is set as a movable part, and also includes any of the above combined hinges, the first member 3 and the second member 4 are respectively provided with a mounting plate 5, the reinforcing connecting member 2 is fixed on the mounting plate 5, and the combined hinge rotatably connects the first member 3 and the second member 4 through the mounting plate 5. By increasing the thickness and the bonding area of ​​the connection part between the hinge and the first member 3 or the second member 4 of the sheet metal part, the strength of the connection part is increased.

[0051] In practical applications, the first component 3 and the second component 4 in the present application can be set as a door frame and a door panel or a box body and a cover body, as well as other scenarios that require a rotational connection.

[0052] The above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Those skilled in the art should understand that the present application includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present application will be included in the scope of the claims.
