Terms defined in commonly used dictionaries are additionally interpreted as having meanings consistent with relevant technical literature and the message of the present disclosure, and shall not be overly interpreted as ideal or very formal meanings unless defined.

[0041] Electronic control components are usually installed in the electric control box by rails, because rails provide a standardized and modular installation method for electronic control components and other electrical equipment. The rail is a structure inside the electric control box, which is usually made of metal material and has a certain size and shape so that electronic control components and other equipment can be clipped on it.

[0042] In order to facilitate the description of the technical solution of the present disclosure, a relay is taken as an example. Figure 1 As shown, a schematic diagram of the guide rail clamping structure disclosed in the present invention is shown, which specifically includes: a base 1, a buckle 2 and a guide rail 3, wherein the base is connected to the relay body 4.

[0043] The structural diagram of the base 1 is shown in FIG. Figure 2 As shown, a protrusion 11 is provided on the base, and the two sides of the protrusion 11 are sawtooth-shaped, and the width and height of each sawtooth are consistent, and a plurality of slots 12 at different positions are formed with the two sides of the base.

[0044] The structural diagram of the buckle 2 is as follows Figure 3 As shown, a limit block 21, 22 adapted to the slot 12 is respectively provided on the left and right sides of the buckle 2, and the limit blocks 21, 22 have a shape and size matching the slot 12; the buckle 2 slides horizontally on the base 1 to change the limit blocks 21, 22 to enter the slot 12 at different positions, so as to fix or release the guide rail 3.

[0045] Specifically, the relay installation in the electric control box usually adopts a modular design, which means that the relay can be easily inserted and removed. The clips and guide rails provide the physical interface of this modular design, so that the relay can be quickly installed and replaced without rewiring or reconnecting.

[0046] In some embodiments, a guide groove (not shown) is respectively provided on both sides of the base 1, and a protrusion matched with the guide groove is provided at the bottom of the buckle for guiding the horizontal sliding of the buckle.

[0047] Specifically, the guide grooves on both sides of the base 1 and the protrusions at the bottom of the buckle 2 are to ensure that the buckle 2 can stably and accurately enter or exit the slot 12 when sliding horizontally. The design of the guide grooves allows the buckle 2 to always move along the side of the base 1 during the sliding process, preventing the buckle 2 from deviating from the track during the sliding process, and the matching protrusions allow the buckle 2 to fit closely with the guide grooves during the sliding process, thereby improving the accuracy and stability of the installation.

[0048] In some embodiments, the contact surface between the base 1 and the buckle 2 has an anti-slip texture or coating.

[0049] Specifically, specific textures are designed on the contact surface of the base and the buckle, such as an uneven surface or a grid-like texture, to increase friction. These textures can increase the roughness of the contact surface, increase the friction coefficient, and thus enhance the anti-slip performance. Alternatively, a coating material with a high friction coefficient and wear resistance can be selected, such as a specially formulated plastic coating or polymer coating. These coating materials can provide good anti-slip performance, while also having certain chemical resistance and high temperature resistance to adapt to different usage environments. In actual applications, the design of the anti-slip texture or coating needs to take into account its durability to ensure that the friction performance of the contact surface can remain stable during long-term use and repeated installation, and will not decrease due to wear.

[0050] In some embodiments, a shock-absorbing pad is provided between the buckle 2 and the base 1 to cushion the vibration generated by the buckle 1 during the process of fixing or releasing the guide rail 3 .

[0051] Specifically, the shock-absorbing pad can effectively absorb and disperse vibration, reducing the impact of vibration generated by the buckle in the process of fixing or releasing the guide rail on the circuit breaker body and surrounding electrical equipment. This helps prevent damage to electrical equipment and extend the service life of the equipment.

[0052] In some embodiments, the limiting blocks 21 and 22 are elastic.

[0053] Furthermore, one end of the limit block is fixedly connected to the side of the buckle 2, and the other end is a free end. When the buckle 2 slides horizontally on the base 1, the free end is elastically deformed to be embedded in or out of the slot 12 at different positions.

[0054] Exemplarily, the limit block is made of spring steel or engineering plastic.

[0055] Specifically, the limit block adopts the design of elastic strip, which can improve the flexibility and adaptability of the buckle structure. When the buckle slides horizontally on the base, the free end will be embedded in or out of the slot at different positions due to elastic deformation, thereby fixing or releasing the guide rail. The elastic strip of spring steel can provide good elasticity and restoring force, and has high strength and wear resistance, which is suitable for use in frequent installation and disassembly processes. The elastic strip of engineering plastic has the advantages of light weight, corrosion resistance, good insulation, etc., and is suitable for different use environments.

[0056] In order to fix the guide rail 3 to the buckle, in the embodiment, a platform protrusion 23 is provided at the front end of the buckle 2; when the buckle 2 slides horizontally to contact the guide rail fold 31, the platform protrusion 23 can tightly buckle the guide rail fold 31, so that the guide rail 3 and the buckle 2 are fixedly connected. This fixing method can ensure that the guide rail remains stable during the installation process and will not shift or fall off due to vibration or external force.

[0057] In a specific example, the card slot 12 includes a first pair of limit card slots 121 and a second pair of limit card slots 122. To better illustrate this embodiment, Figure 4 As shown, when the limit blocks 21 and 22 enter the first pair of limit slots 121, the platform protrusion of the buckle is tightly attached to the guide rail to be fixedly connected; Figure 5 As shown, when the limiting blocks 21 and 22 enter the second pair of limiting slots 122 , the platform protrusion 23 is out of contact with the guide rail 3 , thereby releasing the guide rail 3 .

[0058] It is worth noting that the above-mentioned guide rail clip-on structure is not limited to the installation of the guide rail in the relay and the electric control box, but can also be extended to the fixing and connection of other electronic devices. In other electronic systems such as communication equipment, network equipment, storage equipment, etc., this clip-on structure can also provide a stable and convenient installation solution. In addition, for some electronic components that need to be replaced or upgraded frequently, such as power modules, fans, hard disk drives, etc., this clip-on structure can greatly simplify the process of disassembly and reinstallation, improve work efficiency, and reduce downtime.

[0059] In summary, the present invention uses a sliding buckle to allow the limit block to enter the slot at different positions, thereby fixing or releasing the guide rail, and the operation is simple and quick. In addition, the structure of the present technical solution is simple, which is convenient for inspection and maintenance. When replacement or repair is required, the guide rail can be easily fixed or released by sliding the buckle. Compared with other methods of fixing the guide rail, the guide rail clamping structure of the present invention is more compact, which is conducive to saving space and is particularly suitable for occasions with limited space. In addition, the present invention is also designed with an anti-slip and anti-falling structure, which can effectively prevent the guide rail from accidentally falling off due to vibration and other reasons, thereby ensuring the safety of equipment operation.

[0060] The above embodiments are merely illustrative of the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present disclosure shall still be covered by the claims of the present disclosure.
