Description

TECHNICAL FIELD

[0001] The utility model relates to connecting piece technical field especially relates to quick dismounting and assembling connecting structure and connecting mechanism thereof. BACKGROUND

[0002] When two structural members are fixedly connected, especially when long and flat structural members are butt-jointed along the length direction, rivet connection and screw connection are mostly used, wherein the rivet connection can refer to the rivet connection shown in Figure 1 , Figure 1 , in which two flat rods to be connected are aligned with the mounting holes 51, and then the rivet 8 is passed through the mounting holes 51 of the two flat rods (structural members 5) to rivet and fix the two flat rods; the screw 91 connection can refer to the screw connection shown in Figure 2 , Figure 2 , in which two flat rods (structural members 5) to be connected are aligned with the mounting holes 51, and then the screw 91 is passed through the mounting holes 51 of the two flat rods to be connected and is screw-fixed at the other end with the nut 92.

[0003] In the process of implementing the utility model, the applicant finds that the existing connection mode has at least the following problems:

[0004] 1. The rivet 8 connection mode is usually irreversible once completed, that is, it cannot be easily disassembled or reconnected, which limits its use in some applications that require frequent disassembly or adjustment, and the rivet 8 connection mode requires the use of special tools and equipment, which is relatively complex to install and takes a long time.

[0005] 2. In the process of tightening the nut 92, in addition to the need to provide the screw 91 and the nut 92 for use, a wrench or the like tool is also needed to assist in use during the tightening process, and the installation and disassembly process is also relatively troublesome and time-consuming.

[0006] Therefore, how to solve the above-mentioned problems of the existing connection mode for fixing multiple flat rods, such as the need for additional tools, the complexity of installation, and the long time consumption, has become a research and solution subject of the utility model. UTILITY MODEL CONTENTS

[0007] The utility model aims to provide a quick dismounting and assembling connecting structure and connecting mechanism thereof.

[0008] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions in the first aspect:

[0009] The first aspect of this utility model provides a quick-assembly and disassembly connection structure for quick assembly and disassembly connection of multiple structural components along the length direction. Each of the structural components is provided with mounting holes at the connection points. Its innovation lies in:

[0010] The quick-assembly and disassembly connection structure includes a connector body. The connector body has elastic arms extending distally on the left and right sides. A connection space is formed between the two elastic arms, opening to the distal side and parallel to the front and rear sides of the connector body. The connection space is used to accommodate the parts of multiple structural components to be connected. An elastic action part extending from the distal end to the proximal end of the elastic arm is provided at the inner wall position opposite to the two elastic arms. The maximum distance between the opposing elastic action parts on the two elastic arms is greater than the width of the part of the structural component to be connected, and the minimum distance is less than the width of the part of the structural component to be connected. A positioning post extending distally is provided in the middle of the two elastic arms on the connector body for positioning and cooperating with the mounting hole.

[0011] To achieve the above objectives, the second aspect of this utility model adopts the following technical solution:

[0012] The second aspect of this utility model provides a connecting mechanism, which includes a plurality of structural components, wherein the structural components are connected by a quick-release connecting structure as described in the first aspect of this utility model, and the connecting mechanism includes at least a door and window lock.

[0013] The relevant contents of this utility model are explained as follows:

[0014] 1. The above solution addresses the problems of existing methods for fixing multiple flat rods, such as the need for additional tools, complex installation, and long installation time. Therefore, an innovative quick-assembly and disassembly connection structure is designed that allows for rapid assembly and disassembly without the need for additional tools. This quick-assembly and disassembly connection structure includes a connector body, elastic arms, and positioning posts. The connection space formed between the connector body and the elastic arms provides a place to accommodate the parts of each structural component to be connected. Elastic action parts are provided on the elastic arms on both sides. The maximum distance between the two elastic action parts at their distal ends is greater than the width of the part of the structural component to be connected, and the minimum distance at their proximal ends is less than the width of the part of the structural component to be connected. This allows for easy positioning and connection of the quick-assembly and disassembly connection structure to the parts of the structural component to be connected. During the assembly process, the transition surfaces of the two sides of the structural component to be connected abut against the elastic arms, thus opening the elastic arms and allowing the structural components to be successively installed into the connection space. After all structural components are installed, the elastic arms on both sides return to their original positions under elastic action. The surface of the structural component at the distal end abuts against the proximal part of the elastic action portion on both sides, preventing the structural component from detaching from the quick-assembly connection structure. This enables rapid assembly of multiple structural components. During assembly, the positioning pins and mounting holes can be used for positioning and cooperation, limiting the displacement of each structural component in the length direction, while providing rapid alignment and assembly. When disassembling, the elastic arms on both sides can be opened by hand to allow the structural component to be removed, thus completing the rapid disassembly of the structural component. Through the implementation of the above scheme, the quick-assembly connection structure can be used to quickly assemble and disassemble multiple structural components without the aid of tools, saving time and effort, reducing the difficulty of assembling structural components, and saving assembly time. When subsequent adjustment or maintenance is required, it can also be quickly assembled and disassembled, reducing the time and difficulty of subsequent adjustment or maintenance.

[0015] 2. In the above scheme, the quick-release connection structure is configured to have a connection process state and a connection state. In the connection process state, the mounting holes of the structural components are aligned with the positioning posts, and the part of the structural component to be connected is pressed / pressed into the connection space from the open position at the far end. The two sides of the part to be connected of the structural component abut against the elastic action part of the elastic arm and open the elastic arm until the structural component passes over the elastic action part. In the connection state, after multiple structural components pass over the elastic action part, they are completely entered into the connection space. The positioning posts pass through the mounting holes of multiple structural components, and the elastic arms on both sides return to their original positions under elastic action. The surface of the structural component at the far end abuts against the near end of the elastic action part on both sides to prevent the structural component from detaching from the quick-release connection structure.

[0016] 3. In the above scheme, the elastic action part has a transition surface and a contact surface facing the proximal end. The transition surface abuts against the two sides of the structural component before the structural component is installed in the connection space, so as to provide an expanding force to the left and right sides for the deformation of the two elastic arms. The contact surface abuts against the far end surface of the uppermost connecting structural component after all structural components are installed in the connection space, so as to restrict the structural component from detaching from the quick-release connection structure.

[0017] 4. In the above scheme, the transition surface is an inclined surface or a smooth curved surface, so as to make the process of installing the structural components smoother and without jamming, and facilitate assembly.

[0018] 5. In the above solution, the positioning post is located at the structural center of the quick-assembly and disassembly connection structure. This facilitates production and improves the efficiency, stability, and reliability of quick assembly and disassembly.

[0019] 6. In the above scheme, the bottom of the positioning post is integrally connected to the surface of the elastic action part and is a columnar body extending toward the far end. The cross-sectional shape of the positioning post is circular, annular, cross-shaped, grid-shaped, equilateral polygonal or star-shaped.

[0020] 7. In the above scheme, the elastic arm is located at the left and right ends of the main body of the connector, and the outer side of the elastic arm is inclined towards the center. This design allows the elastic effect of the elastic arm to be more effective, resulting in higher overall strength of the quick-disassembly connection structure and easier quick disassembly.

[0021] 8. In the above scheme, the structural component is a long and flat structure. The structural component is provided with multiple mounting holes spaced apart along its length at the part to be connected. The positioning post selectively positions and connects with one of the mounting holes, so as to adjust the installation position and length between the structural components.

[0022] 9. In the above scheme, the structural component is a long and flat structure, and the structural component is provided with a plurality of mounting holes spaced apart along its length at the part to be connected. The main body of the connector is provided with a number of positioning posts greater than 2 and less than the number of mounting holes.

[0023] 10. In the above solution, the main body of the connector, the elastic arm, and the positioning column are integrally formed to facilitate production and material management on site, thereby reducing the number of parts used to one.

[0024] 11. In the above solution, the main body of the connector, the elastic arm, and the positioning post are made of elastic plastic or metal. Compared with materials such as metal, plastic is lighter, which makes the elastic component 3 more convenient to use and helps to reduce the overall weight. Using metal makes the structure more robust; alternatively, a polymer material that combines the advantages of both plastic and metal can be used.

[0025] 12. In the above scheme, the quick-release connection structure includes a gasket. The gasket is assembled between the surface of the structural component located at the far end and the abutment surface of the elastic action part facing the near end. In this way, when structural components of different sizes and specifications are not perfectly matched with the quick-release connection structure, the gasket can be used as thickness compensation for the structural component, so that different structural components can be used.

[0026] 13. In the above scheme, the gasket has a deformable part that can stretch and deform from the proximal end to the distal end or from the distal end to the proximal end, so that a gasket can be used to adjust different sizes.

[0027] 14. In the above scheme, the gasket has an upper surface for abutting against the elastic part, and the deformable part protrudes upward or downward a certain distance before abutting against the surface of the structural member.

[0028] 15. In the above solution, the deformable part is composed of multiple elastic legs that surround the inner ring of the gasket. There is a gap between each elastic leg, and a through hole is formed in the middle of the multiple elastic legs for the positioning post to pass through. The application of the gasket with this deformable part can better match the elastic arm and positioning post in the quick-release connection structure, with high fit and convenient use.

[0029] 16. In the above solution, the gasket and the deformable part are integrally formed, which facilitates production and reduces the number of parts.

[0030] 17. In the above solution, the gasket and deformable part are made of elastic plastic or metal. Compared with materials such as metal, plastic is lighter, making the deformable part more convenient to use and helping to reduce the overall weight. Using metal provides a more robust structure; alternatively, a polymer material that combines the advantages of both plastic and metal can be used.

[0031] 18. In this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] 19. In this utility model, the terms “center”, “front”, “rear”, “axial”, “bottom”, “inner”, “outer”, etc., indicate the orientation or positional relationship based on the orientation or positional assembly relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0033] 20. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] Due to the application of the above solution, this utility model has the following advantages and effects compared with the prior art:

[0035] 1. The above-mentioned solution of this utility model addresses the problems of existing methods for fixing multiple flat rods, such as the need for additional tools, complex installation, and long installation time. It innovatively designs a quick-disassembly and assembly connection structure that can be quickly assembled and disassembled without the need for additional tools.

[0036] 2. In the above-described solution of this utility model, the quick-assembly and disassembly connection structure includes a connector body, elastic arms, and positioning posts. The connection space formed between the connector body and the elastic arms provides a place to accommodate the parts of each structural component to be connected. Elastic action parts are provided on the elastic arms on both sides. The maximum distance between the two elastic action parts at their far ends is greater than the width of the part of the structural component to be connected, and the minimum distance at their near ends is less than the width of the part of the structural component to be connected. This allows the quick-assembly and disassembly connection structure to be positioned and connected to the part of the structural component to be connected, so that the transition surfaces of the parts of the structural component to be connected abut against the transition surfaces of the elastic arms and support the elastic arms. The structure is opened to allow structural components to be successively installed into the connecting space. After all structural components are installed, the elastic arms on both sides return to their original positions under elastic action. The surface of the structural component at the far end abuts against the near end of the elastic action part on both sides to prevent the structural component from detaching from the quick-assembly and disassembly connection structure. This allows for the rapid assembly of multiple structural components. During the assembly process, the positioning pins and mounting holes can be used for positioning and cooperation to limit the displacement of each structural component in the length direction, while providing the function of quick alignment and quick assembly. When disassembling, the elastic arms on both sides can be opened by hand to allow the structural component to be removed, thus completing the quick disassembly of the structural component.

[0037] 3. In summary, by implementing the above solutions, this quick-assembly and disassembly connection structure can be used to quickly connect and disassemble multiple structural components without the aid of tools. This saves time and effort, reduces the difficulty of assembling structural components, and saves assembly time. It also allows for quick assembly and disassembly when adjustments or maintenance are needed later, reducing the time and difficulty of subsequent adjustments or maintenance. This quick-assembly and disassembly connection structure can be used in the door locks of new energy storage cabinets as a connection between the lock and the locking point, and between connecting rods and bolts.

[0063] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0064] This utility model aims to solve the problems of existing methods for fixing multiple flat rods, such as the need for additional tools, complex installation, and long installation time. It innovatively designs a quick-disassembly and assembly connection structure that can be quickly assembled and disassembled without the need for additional tools.

[0065] Example 1, as Figures 3 to 12 As shown in Embodiment 1 of this utility model, a quick-assembly and disassembly connection structure is disclosed for quick assembly and disassembly connection of multiple structural components 5 along the length direction. Each of the structural components 5 is provided with a mounting hole 51 at the part to be connected. The quick-assembly and disassembly connection structure includes a connector body 1. The connector body 1 is provided with elastic arms 2 extending toward the distal end on the left and right sides. A connection space 20 is formed between the two elastic arms 2 facing each other and open on the distal side and parallel to the front and rear sides of the connector body 1. The connection space 20 is used to accommodate the parts to be connected of multiple structural components 5. An elastic action part 21 extending from the distal end to the proximal end of the elastic arm 2 is provided at the inner wall position opposite to the two elastic arms 2. The maximum distance between the opposing elastic action parts 21 on the two elastic arms 2 is greater than the width of the part to be connected of the structural component 5, and the minimum distance is less than the width of the part to be connected of the structural component 5. A positioning post 3 extending toward the distal end and used for positioning and cooperating with the mounting hole 51 is provided in the middle of the two elastic arms 2 on the connector body 1.

[0066] This quick-assembly and disassembly connection structure includes a connector body 1, elastic arms 2, and positioning posts 3. A connection space 20 formed between the connector body 1 and the elastic arms 2 provides a space for the parts of each structural component 5 to be connected. Elastic actuating parts 21 are provided on the left and right elastic arms 2. The maximum distance between the two elastic actuating parts 21 at their distal ends is greater than the width of the part of the structural component 5 to be connected, and the minimum distance at their proximal ends is less than the width of the part of the structural component 5 to be connected. This allows the quick-assembly and disassembly connection structure to be positioned and connected to the part of the structural component 5, with the elastic arms 21 positioned on both sides of the part to be connected. The transition surfaces 211 abut against each other and open the elastic arms 2 so that the structural components 5 can be successively installed into the connecting space 20. After all the structural components 5 are installed, the elastic arms 2 on both sides return to their original positions under elastic action. The surface of the structural component 5 located at the far end abuts against the part of the elastic action part 21 located on both sides facing the near end, so as to restrict the structural component 5 from detaching from the quick-assembly and disassembly connection structure. This enables the quick assembly of multiple structural components 5. During the assembly process, the positioning pins 3 and the mounting holes 51 can be positioned and engaged to restrict the displacement of each structural component 5 in the length direction, while providing the function of quick alignment and quick assembly.

[0067] When disassembling, use your hands to pry open the spring arms on both sides so that structural component 5 can be detached, thus completing the quick disassembly of structural component 5.

[0068] In the first embodiment of this utility model, the quick-assembly and disassembly connection structure is configured to have a connection process state and a connection state.

[0069] During the connection process, such as Figure 9 As shown, the mounting hole 51 of the structural component 5 is aligned with the positioning post 3. The part of the structural component 5 to be connected is pressed / pressed into the connection space 20 from the open position at the far end. The two sides of the part of the structural component 5 to be connected abut against the elastic action part 21 of the elastic arm 2 and open the elastic arm 2 until the structural component 5 passes the elastic action part 21.

[0070] In the connected state, such as Figure 10 , Figure 11 , Figure 12 As shown, after passing the elastic action part 21, the multiple structural components 5 completely enter the connection space 20. The positioning post 3 passes through the mounting holes 51 of the multiple structural components 5. The elastic arms 2 on both sides return to their original positions under the elastic action. The surface of the structural component 5 located at the far end abuts against the near end of the elastic action part 21 located on both sides, so as to restrict the structural component 5 from detaching from the quick-release connection structure.

[0071] In the first embodiment of this utility model, as Figure 3 , Figure 4As shown, the elastic action part 21 has a transition surface 211 and an abutment surface 212 facing the proximal end. The transition part abuts against the two sides of the structural member 5 before the structural member 5 is installed into the connecting space 20, so as to provide an expanding force to the left and right sides for the deformation of the two elastic arms 2. The abutment surface 212 abuts against the far end surface of the uppermost connecting structural member 5 after each structural member 5 is installed into the connecting space 20, so as to restrict the structural member 5 from detaching from the quick-release connecting structure.

[0072] Specifically, the transition surface 211 is an inclined surface or a smooth curved surface, so as to make the process of installing the structural component 5 smoother and without jamming, and facilitate assembly.

[0073] In this first embodiment of the present invention, the positioning post 3 is located at the structural center of the quick-assembly and disassembly connection structure. This facilitates production and improves the efficiency, stability, and reliability of quick assembly and disassembly.

[0074] Furthermore, the bottom of the positioning post 3 is integrally connected to the surface of the elastic actuating part 21, and it is a columnar body extending towards the distal end. The cross-sectional shape of the positioning post 3 is circular, annular, cross-shaped, grid-shaped, equilateral polygonal, or star-shaped. Figures 3 to 5 The following views are shown, in which the circular positioning post 3 is used. Figures 6 to 8 The diagram shows various views of the cross-shaped positioning post 3. This invention is not limited to this and may also have other shapes.

[0075] In the first embodiment of this utility model, the elastic arm 2 is located at the left and right ends of the main body of the connector, and the outer side of the elastic arm 2 is inclined towards the center. This design allows the elastic effect of the elastic arm 2 to be more effective, resulting in higher overall strength of the quick-disassembly and assembly connection structure and making it easier to disassemble and assemble quickly.

[0076] In the first embodiment of this utility model, the structural component 5 is a long, flat structure. The structural component 5 has multiple mounting holes 51 spaced apart along its length at the connection point. The positioning post 3 selectively connects to one of the mounting holes 51, thereby adjusting the installation position and length between the structural components 5. This utility model is not limited to this; it can also be configured such that the structural component 5 is a long, flat structure, the structural component 5 has multiple mounting holes 51 spaced apart along its length at the connection point, and the connecting body 1 has more than two positioning posts 3, but fewer than the number of mounting holes 51.

[0077] In this first embodiment of the present invention, the connector body 1, the elastic arm 2, and the positioning post 3 are integrally formed, which facilitates production and on-site material management, reducing the number of parts used to one. More specifically, the connector body 1, the elastic arm 2, and the positioning post 3 are made of elastic plastic or metal. Compared with materials such as metal, plastic is lighter, making the elastic component 3 more convenient to use and helping to reduce the overall weight. Using metal provides a more robust structure; alternatively, a polymer material that combines the advantages of both plastic and metal can be used.

[0078] Example 2, as Figures 13 to 15 As shown, Embodiment 2 of this utility model discloses a quick-assembly and disassembly connection structure for quick assembly and disassembly connection of multiple structural components 5 along the length direction. Each structural component 5 is provided with a mounting hole 51 at the connection point. The thickness of each structural component 5 can be uniform or non-uniform. The quick-assembly and disassembly connection structure includes a connector body 1, elastic arms 2, positioning posts 3, and gaskets 4. The connector body 1 is provided with elastic arms 2 extending towards the distal end on the left and right sides. Two elastic arms 2 are arranged opposite each other, forming a distal side and a parallel side to the front of the connector body 1. The rear two open connection spaces 20 are used to accommodate the connection parts of multiple structural components 5. Elastic action parts 21 extending from the distal end to the proximal end of the two elastic arms 2 are provided on the inner walls opposite each other. The maximum distance between the opposing elastic action parts 21 on the two elastic arms 2 is greater than the width of the connection part of the structural component 5, and the minimum distance is less than the width of the connection part of the structural component 5. A positioning post 3 extending towards the distal end is provided on the main body 1 of the connector between the two elastic arms 2 for positioning and engaging with the mounting hole 51. A gasket 4 is assembled between the surface of the structural component 5 located at the distal end and the abutment surface 212 of the elastic action part 21 facing towards the proximal end. This allows the gasket 4 to compensate for the thickness of the structural component 5 when different sizes and specifications of structural components 5 are not perfectly matched with the quick-release connection structure, thus enabling the use of different structural components 5.

[0079] In the second embodiment of this utility model, the quick-assembly and disassembly connection structure is configured to have a connection process state and a connection state.

[0080] During the connection process, such as Figure 13As shown, the mounting hole 51 of the structural component 5 is aligned with the positioning post 3. The part of the structural component 5 to be connected is pressed / pressed into the connection space 20 from the open position at the far end. The two sides of the part of the structural component 5 to be connected abut against the elastic action part 21 of the elastic arm 2 and open the elastic arm 2 until the structural component 5 passes the elastic action part 21. Since the thickness of the two structural components 5 is less than the height of the connection space 20, a gasket 4 is then inserted into the connection space 20.

[0081] In the connected state, such as Figure 14 As shown, after passing the elastic action part 21, the multiple structural components 5 completely enter the connection space 20. The positioning post 3 passes through the mounting holes 51 of the multiple structural components 5. The elastic arms 2 on both sides return to their original positions under the elastic action. The gasket 4 is assembled between the surface of the structural component 5 located at the far end and the abutment surface 212 of the elastic action part 21 facing the near end, so as to restrict the structural component 5 from detaching from the quick-release connection structure.

[0082] In the second embodiment of this utility model, as Figure 15 As shown, the gasket 4 has a deformable portion 41 that stretches and deforms from the proximal end to the distal end or from the distal end to the proximal end, thereby allowing one gasket 4 to be adapted to different sizes.

[0083] In the second embodiment of this utility model, the gasket 4 has a deformable part 41 that can stretch and deform from the proximal end to the distal end or from the distal end to the proximal end, so that one gasket 4 can be used to adjust different sizes.

[0084] In the second embodiment of this utility model, the gasket 4 has an upper surface for abutting against the elastic action part 21, and the deformable part 41 protrudes upward or downward a certain distance before abutting against the surface of the structural member 5.

[0085] In the second embodiment of this utility model, the deformable part 41 is composed of multiple elastic support legs 411 that surround the inner ring of the gasket. There is a gap between each elastic support leg 411, and a through hole 412 for the positioning post 3 to pass through is formed in the middle of the multiple elastic support legs 411. The application of the gasket 4 with this deformable part 41 can better cooperate with the elastic arm 2 and the positioning post 3 in the quick disassembly and assembly connection structure, with high fit and convenient use.

[0086] In the second embodiment of this utility model, the gasket and the deformable part 41 are integrally molded, which facilitates production and reduces the number of parts. More specifically, the gasket and the deformable part 41 are made of elastic plastic or metal. Compared with materials such as metal, plastic is lighter, making the deformable part 41 more convenient to use and helping to reduce the overall weight.
