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

[0004] 1, the rivet 8 connection mode, the rivet 8 connection is completed once, usually is irreversible, namely cannot be easily disassembled or reconnected, which limits its use in some applications that need to be frequently disassembled or adjusted, and the rivet 8 connection mode needs to use special tools and equipment, and the installation is relatively complex, and the time consumption is relatively long.

[0005] 2, the screw 91 connection mode, in the process of tightening the nut 92, in addition to the need of being equipped with the screw 91, the nut 92 is used, and the wrench is used to assist in the process of tightening, and the installation process is relatively troublesome, and the time consumption is relatively long.

[0006] Therefore, how to solve the problems of the existing mode for fixing multiple connecting rods, such as complex installation and long time consumption, has become the research and solution of the utility model. UTILITY MODEL CONTENT

[0007] The utility model aims at providing quick -witted connection structure and its mechanism to make the assembly of mechanism more quickly and conveniently.

[0008] To achieve the above object, the utility model first aspect adopts the technical scheme that:

[0009] The utility model first aspect provides a kind of quick -witted connection structure, and its innovation point is:

[0010] The quick -witted connection structure includes connecting piece, connecting rod.

[0011] The connector has a base, a connector, and a locking platform. Two connectors are disposed on the base, one on the left and one on the right. A receiving space for accommodating the connecting rod is formed between the two connectors and opens upward. The locking platform is disposed on the inner wall opposite to the pair of connectors and has a locking surface facing downward.

[0012] The connecting rod has a main body, on which a snap-fit ​​part is provided, and the snap-fit ​​part has a snap-fit ​​space for limiting the forward and backward displacement of the connecting member.

[0013] The quick-connect structure is configured to have an installation state, in which at least two of the connecting rods overlap and are installed into the receiving space of the connector. The connecting part of the connector is positioned and engaged with the snap-fit ​​space of each of the connecting rods. The snap-fit ​​surface of the locking platform abuts against the upper surface of the connecting rod located at the upper end to prevent each of the connecting rods from disengaging from above.

[0014] To achieve the above objectives, the technical solution adopted in the second aspect of this utility model is as follows: the second aspect of this utility model provides a mechanism, which includes at least one quick-connect structure as described in the first aspect of this utility model, and the mechanism is at least a door or window lock.

[0015] The relevant contents of this utility model are explained as follows:

[0016] 1. In the above solution, the existing methods for fixing multiple connecting rods have problems such as complex installation and long installation time. Therefore, an innovative quick-installation connection structure is designed that can be installed quickly without the use of additional tools. This quick-installation connection structure includes connectors and connecting rods. The connector has a base, a connecting body, and a locking platform. The connecting rod has a structural body with a locking part. In the installation state, the locking parts of each connecting rod overlap and are installed into the receiving space of the connector. The connecting part of the connector and the locking space of each connecting rod are positioned and matched. The locking surface of the locking platform abuts against the upper surface of the connecting rod at the top to prevent the connecting rod from detaching from the top. With this design, two or more connecting rods with locking parts and locking spaces that need to be fixed together can be quickly installed with a practical connector without other tools, thereby reducing the assembly time and assembly difficulty of door and window lock systems with multiple connecting rod structures. The snap-fit ​​space limits the displacement of the connector and connecting rod in the front-to-back direction, and the snap-fit ​​surface of the snap-fit ​​platform prevents the connecting rod from disengaging in the vertical direction. This allows the quick-installation connection structure to have a fast installation function while also ensuring robustness and stability. As a result, it can replace existing rivet and screw connections, and also save on assembly costs and improve assembly efficiency.

[0017] 2. In the above solution, the lower end of the connector is connected to the base. The connector is a spring-arm structure extending from the lower end to the upper end, which allows the connector to deform to a certain extent during the process of inserting the connecting rod into the receiving space. The boss can better move away from the outer sides and recover its elastic deformation after insertion, so that the locking platform of the connector can lock and fix the connecting rod. This utility model is not limited to this. The base of the connector can also be made into an elastic structure, and the elastic deformation of the base can cause the connector to tilt and separate to the left and right sides. Alternatively, both the base and the connector can be made into elastic structures, and the corresponding separation and automatic recovery can be completed by the joint elastic deformation of the base and the connector.

[0018] 3. In the above scheme, the connecting body extends from the lower end to the upper end and is divided into a first section, a second section, and a third section. The card platform is located in the second section, thereby making the formation of the accommodating space more reasonable. The accommodating space can be located between the card platforms of the first and second sections. The segmented distribution can also better utilize the cooperative function of the elastic arm structure in the connecting body. This utility model is not limited to this and can also be set to two sections.

[0019] 4. In the above scheme, the first segment is inclined inward from the bottom to the top so that the distance between the two connecting bodies at the bottom gradually increases and decreases. This makes the space larger at the bottom and smaller at the top of the first segment, making it easier to install the connecting rod in front and more secure to install the connecting rod in back, thereby achieving both installation efficiency and installation stability of each connecting rod.

[0020] 5. In the above scheme, the third segment is inclined outward from the bottom to the top so that the distance between the two connecting bodies in the open part facing the top gradually increases, thereby allowing the connecting rod to have a larger open part for insertion, which facilitates the quick insertion of the connecting rod.

[0021] 6. In the above solution, the inner side of the locking platform has a transition surface extending from the upper end to the lower end. The transition surface is an inclined surface, a smooth curved surface, or an arc surface. The transition surface extends to the locking surface, so as to make the process of inserting the connecting rod smoother and without jamming, and facilitate assembly.

[0022] 7. In the above solution, the connecting rod is a flat, elongated strip structure extending longitudinally. The snap-fit ​​part is composed of snap-fit ​​grooves on both sides of the connecting rod in the width direction. The snap-fit ​​grooves form the snap-fit ​​space, and the snap-fit ​​grooves have limiting surfaces in the longitudinal direction for abutting against the front and rear surfaces of the connector in the installed state. This allows the snap-fit ​​part in the connecting rod to better engage with the connecting body of the connector, resulting in a sufficiently high overall structural strength and good stability of the quick-connect structure in the installed state. Furthermore, arc-shaped process grooves are provided on the inward-facing sides of the snap-fit ​​grooves to facilitate the stamping formation of the snap-fit ​​grooves.

[0023] 8. In the above solution, the base, connector, and mounting plate are integrally formed. This facilitates production and on-site material management, reducing the number of connecting parts to a single component. The mounting plate can be formed by embossing.

[0024] 9. In the above solution, the connector is made entirely of elastic plastic or metal. Compared to materials like metal, plastic is lighter, making the connector more convenient to use and helping to reduce overall weight. Using metal results in a more robust structure and smaller size. Alternatively, a polymer material combining the advantages of both plastic and metal can be used.

[0025] 10. 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.

[0026] 11. 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.

[0027] 12. 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.

[0028] Due to the application of the above solution, this utility model has the following advantages and effects compared with the prior art:

[0029] 1. The above-mentioned solution of this utility model addresses the problems of complex installation and long time consumption in existing methods of fixing multiple connecting rods. It innovatively designs a quick-installation connection structure that can be installed quickly without the need for additional tools. This quick-installation connection structure includes connectors and connecting rods. The connector has a base, a connecting body, and a locking platform. The connecting rod has a structural body with a locking part. In the installation state, the locking parts of each connecting rod overlap and are installed into the receiving space of the connector. The connecting part of the connector and the locking space of each connecting rod are positioned and matched. The locking surface of the locking platform abuts against the upper surface of the connecting rod at the upper end to prevent the connecting rod from detaching from the top. This design allows for the quick installation of two or more connecting rods with locking parts and locking spaces that need to be fixed together, without the need for other tools, thereby reducing the assembly time and assembly difficulty of door and window lock systems with multiple connecting rod structures.

[0030] 2. The above-mentioned solution of this utility model limits the displacement of the connecting parts and connecting rods in the front-to-back direction by the snap-fit ​​space, and prevents the connecting rods from disengaging in the vertical direction by the snap-fit ​​surface of the snap-fit ​​platform. This allows the quick-installation connection structure to achieve both rapid installation and robustness and stability, thus replacing existing rivet and screw connections, saving assembly costs and improving assembly efficiency. This quick-installation 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 the connecting rods and bolts.

[0051] 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.

[0052] This utility model aims to solve the problems of complex installation and long time consumption in the existing methods of fixing multiple connecting rods 2. It innovatively designs a quick-installation connection structure that can be installed quickly without the use of additional tools. This quick-installation connection structure can be used in the door lock of new energy storage cabinet as a connection between the lock and the locking point, and between the connecting rod 2 and the bolt body, thereby reducing the assembly time and assembly difficulty of door and window lock systems with multiple connecting rods 2.

[0053] Example 1, as Figures 3 to 9 As shown in the figure, Embodiment 1 of this utility model discloses a quick-connection structure, which includes a connector 1 and a connecting rod 2.

[0054] like Figures 3 to 8 As shown, the connector 1 has a base 11, a connector 12, and a locking platform 13. Two connectors 12 are disposed on the base 11, and a receiving space 120 is formed between the two connectors 12, which is open to the upper end to accommodate the connecting rod 2. The locking platform 13 is disposed on the inner wall opposite to the pair of connectors 12, and the locking platform 13 has a locking surface 131 facing the lower end.

[0055] like Figure 9 As shown, the connecting rod 2 has a structural body 21, and a snap-fit ​​part 22 is provided on the structural body 21. The snap-fit ​​part 22 has a snap-fit ​​space 220 for limiting the front and rear displacement of the connecting member 1.

[0056] like Figures 11 to 13 As shown, the quick-connect structure is configured to have an installation state. In the installation state, the snap-fit ​​portions 22 of at least two of the connecting rods 2 are overlapped and installed into the receiving space 120 of the connector 1. The connecting portion of the connector 1 is positioned and engaged with the snap-fit ​​space 220 of each of the connecting rods 2. The snap-fit ​​surface 131 of the snap-fit ​​platform 13 abuts against the upper surface of the connecting rod 2 located at the upper end to restrict each of the connecting rods 2 from disengaging from above.

[0057] exist Figure 10 The diagram shows the installation process: align the opening of connector 1 with the snap-fit ​​part 22 of connecting rod 2, and then press down to quickly connect the two connecting rods 2 together.

[0058] The connection function in the width direction is achieved by using the protrusions on both sides of the connecting body 12 on the connector 1 to hold the connecting rod 2, and the connection function in the length direction is achieved by using the connecting body 12 on the connector 1 to hold the connecting space 220 on both sides of the connecting rod 2.

[0059] In Embodiment 1 of this utility model, as Figure 4As shown, the lower end of the connector 12 is connected to the base 11. The connector 12 is a spring arm structure extending from the lower end to the upper end, so that the connector 12 can undergo a certain deformation during the process of inserting the connecting rod 2 into the receiving space 120. The boss can better move away from the outer sides and recover its elastic deformation after insertion, so that the locking platform 13 of the connector 1 can lock and fix the connecting rod 2. This utility model is not limited to this. The base 11 of the connector 1 can also be made into an elastic structure, and the elastic deformation of the base 11 can cause the connector 12 to tilt and separate to the left and right sides. Alternatively, both the base 11 and the connector 12 of the connector 1 can be made into elastic structures, and the corresponding separation and automatic recovery can be completed by the joint elastic deformation of the base 11 and the connector 12.

[0060] In the first embodiment of this utility model, as Figure 4 , Figure 5 As shown, the connecting body 12 extends from the lower end to the upper end and is sequentially divided into a first segment 121, a second segment 122, and a third segment 123. The locking platform 13 is disposed in the second segment 122, thereby making the formation of the accommodating space 120 more reasonable. The accommodating space 120 can be located between the locking platform 13 of the first segment 121 and the second segment 122. The segmented distribution can also better utilize the cooperative function of the spring arm structure in the connecting body 12. This utility model is not limited to this and can also be configured as two segments.

[0061] Specifically, such as Figure 4 , Figure 8 As shown, the first segment 121 is inclined inward from the lower end to the upper end, so that the distance between the receiving space 120 between the two connecting bodies 12 gradually increases and decreases at the lower end. This makes the receiving space 120 larger at the lower end and smaller at the upper end of the first segment 121, making it easier to install the connecting rod 2 in front and more secure to install the connecting rod 2 in the back, thereby achieving both installation efficiency and installation stability of each connecting rod 2.

[0062] Furthermore, such as Figure 4 , Figure 8 As shown, the third segment 123 is inclined outward from the lower end to the upper end, so that the distance between the two connecting bodies 12 gradually increases in the open part facing the upper end, thereby allowing the connecting rod 2 to have a larger open part for insertion, which facilitates the quick insertion of the connecting rod 2.

[0063] In the first embodiment of this utility model, as Figure 5 , Figure 6 , Figure 8 As shown, the inner side of the mounting plate has a transition surface 132 extending from the upper end to the lower end. The transition surface 132 is an inclined surface, a smooth curved surface, or an arc surface. The transition surface extends to the locking surface 131, so as to make the process of inserting the connecting rod 2 smoother and without jamming, and facilitate assembly.

[0064] In the first embodiment of this utility model, as Figure 9 As shown, the connecting rod 2 is a flat, elongated structure extending longitudinally. The locking part 22 is composed of locking grooves 221 on both sides of the connecting rod 2 in the width direction. The locking grooves 221 form the locking space 220. The locking grooves 221 have limiting surfaces 222 in the longitudinal direction for abutting against the front and rear surfaces of the connector 1 in the installed state. This allows the locking part 22 in the connecting rod 2 to better engage with the connecting body 12 of the connector 1, resulting in a sufficiently high overall structural strength and good stability of the quick-connect structure in the installed state. In addition, arc-shaped process grooves are provided on the inward sides of the locking grooves 221 to facilitate the stamping formation of the locking grooves 221.

[0065] In the first embodiment of this utility model, as Figures 4 to 8 As shown, the base 11, connector 12, and mounting bracket 13 are integrally molded. This facilitates production and on-site material management, reducing the number of components used in connector 1 to a single piece. The mounting bracket 13 can be formed by embossing. More specifically, connector 1 is made entirely of elastic plastic or metal. Compared to metal, plastic is lighter, making connector 1 more portable and contributing to overall weight reduction. Using metal results in a more robust structure and smaller size. Alternatively, a polymer material combining the advantages of both plastic and metal can be used.

[0066] Embodiment 2 discloses a mechanism that includes at least one quick-connection structure as described in the first aspect of the present invention. The mechanism includes at least a door and window lock. In the door and window lock, the connection between the lock and the locking point, and the connection between the connecting rod 2 and the bolt body can all adopt the quick-connection structure. The door and window lock includes new energy storage cabinets, subway and high-speed rail electrical cabinet locks, and door and window locks, etc.

[0067] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
