[0034] Referring to Figures 1 to 5 As shown, this embodiment provides a guide rail buckle structure, and the guide rail buckle structure includes a base 100 and a clamping plate 200.

[0035] Specifically, a first boss 110 and a second boss 120 are provided at intervals along the first direction at the bottom of the base 100, a limiting groove 102 is formed between the first boss 110 and the second boss 120, a sliding channel 111 is provided on the first boss 110 and is connected to the limiting groove 102, and the sliding channel 111 extends along the first direction; the clamping plate 200 includes a sliding plate portion 210 and a clamping portion 220, the sliding plate portion 210 is slidably passed through the sliding channel 111, the clamping portion 220 is provided at one end of the sliding plate portion 210 facing the second boss 120, the clamping plate 200 can clamp the guide rail into the limiting groove 102 through the clamping portion 220, and the clamping portion 220 is protruding from the sliding plate portion 210 along the second direction toward one side of the bottom of the limiting groove 102. Among them, direction a in the figure is the first direction, the first direction can be the length direction of the guide rail snap-in structure, direction b is the second direction, the second direction can be the height direction of the guide rail snap-in structure, and direction c is the third direction, the third direction can be the width direction of the guide rail snap-in structure.

[0036] In this embodiment, the clamping portion 220 of the clamping plate 200 is arranged to protrude from the sliding plate portion 210 along the second direction toward one side of the bottom of the limiting groove 102, so that the sliding channel 111 matched with the sliding plate portion 210 is formed relative to the internal installation space of the base 100, thereby ensuring the internal installation space of the base 100, which is conducive to the design and control of the electrical safety distance. In addition, the clamping plate 200 clamps the guide rail into the limiting groove 102 through the clamping portion 220, which is convenient and reliable.

[0037] It is understandable that a mounting groove 101 is provided on the top of the base 100 , and the sliding channel 111 is formed to give way relative to the mounting groove 101 , which is beneficial to the design and control of the electrical safety distance in the mounting groove 101 .

[0038] Specifically, a clamping protrusion 121 is provided on one side of the second boss 120 along the first direction toward the first boss 110 . The clamping protrusion 121 cooperates with the clamping portion 220 to clamp the guide rail into the limiting groove 102 , which is convenient and reliable.

[0039] Exemplarily, at least one clamping protrusion 121 is provided, for example, a plurality of clamping protrusions 121 are provided at intervals along the third direction.

[0040] Exemplarily, the card board 200 is provided with at least one.

[0041] In this embodiment, a plurality of wiring frames (not shown) that can be electrically connected to external wires are provided in the installation groove 101. Some of the wiring frames correspond to the first boss 110 in the second direction. By arranging the clamping portion 220 of the clamping plate 200 to protrude from the sliding plate portion 210 toward the bottom of the limiting groove 102 in the second direction, the adjustable space of the wiring frame can be increased, which is beneficial to the sunken design of the wiring frame toward the bottom of the first boss 110, effectively ensuring the electrical safety distance of the wiring frame. Herein, the wiring frame sinking toward the bottom of the first boss 110 means that the wiring frame moves and adjusts its position toward the bottom of the first boss 110.

[0042] It is worth mentioning that the installation groove 101 can extend into the first boss 110 to further increase the installation space of the installation groove 101.

[0043] In this embodiment, referring to Figures 2 to 4 as shown, an elastic member 230 is provided on the sliding plate portion 210. The elastic member 230 is configured to provide a force for the clamping portion 220 to clamp the guide rail, so as to prevent the guide rail buckle structure from disengaging from the guide rail, which is stable and reliable.

[0044] Specifically, the elastic member 230 includes two elastic arms 231 spaced apart in the third direction. The two elastic arms 231 are configured to provide a force for the clamping portion 220 to clamp the guide rail. Further specifically, a first through hole 211 is provided on the sliding plate portion 210. The first side wall of the first through hole 211 in the first direction is connected to the first end of the elastic arm 231. The second end of the elastic arm 231 extends toward the second side wall of the first through hole 211 in the first direction, and a guiding protrusion 232 extending toward the bottom of the first boss 110 is provided at the second end of the elastic arm 231. In this embodiment, by arranging the elastic arm 231 in the first through hole 211, the thickness of the sliding plate portion 210 can be reduced, so that the sliding channel 111 forms a good clearance with respect to the installation groove 101.

[0045] Specifically, a clearance hole 112 communicating with the sliding channel 111 is provided at the bottom of the first boss 110. A guiding portion 130 is provided in the clearance hole 112. First guiding surfaces 131 are respectively provided on both sides of the guiding portion 130 in the third direction. The periphery of the guiding protrusion 232 abuts against the corresponding first guiding surface 131, enabling the sliding plate portion 210 to have a tendency to slide toward the second boss 120, so that the clamping portion 220 can clamp the guide rail, which is stable and reliable.

[0046] Exemplarily, the first guide surface 131 may be a plane. Specifically, the two first guide surfaces 131 are arranged at an angle and are symmetrically arranged relative to the first direction. The guide protrusions 232 and the first guide surfaces 131 are in one-to-one correspondence and mutually abut against each other. It can be understood that the guide protrusions 232 clamp the two first guide surfaces 131 under the elastic force of the elastic arm 231, and by squeezing the first guide surfaces 131, the sliding plate portion 210 has a tendency to slide toward the second boss 120, which is stable and reliable. Of course, the first guide surface 131 can also be set as a curved surface or a surface of other shapes, which is not limited in this application.

[0047] Specifically, the guide portion 130 may be provided with a second guide surface 132 on both sides along the third direction, the second guide surface 132 is connected to the first guide surface 131 on the corresponding side, and the second guide surface 132 is provided on the side of the first guide surface 131 facing away from the second boss 120 along the first direction, and the circumference of the guide protrusion 232 abuts against the second guide surface 132 on the corresponding side, so that the sliding plate portion 210 has a tendency to slide away from the second boss 120. In this embodiment, the sliding plate portion 210 slides in the sliding channel 111, so that the guide protrusion 232 switches between the first guide surface 131 and the second guide surface 132. Among them, the guide protrusion 232 is abutted against the first guide surface 131, so that the sliding plate part 210 can slide toward the second boss 120, and the clamping part 220 clamps the guide rail; the guide protrusion 232 is abutted against the second guide surface 132, so that the sliding plate part 210 can slide back to the second boss 120, and the clamping part 220 retracts into the sliding channel 111, and the clamping part 220 is separated from the guide rail, which facilitates the disassembly and assembly of the guide rail snap structure relative to the guide rail.

[0048] Exemplarily, the second guide surface 132 may be a plane. Specifically, the two second guide surfaces 132 are arranged at an angle and are symmetrically arranged relative to the first direction. It can be understood that the first guide surface 131 and the second guide surface 132 may be surrounded by a diamond plate. Of course, the second guide surface 132 may also be a curved surface or a surface of other shapes, which is not limited in this application.

[0049] More specifically, the guide portion 130 may be provided with third guide surfaces 133 on both sides along the third direction, the first end of the third guide surface 133 is connected to the corresponding first guide surface 131, and the second end of the third guide surface 133 is connected to the hole wall of the clearance hole 112. Exemplarily, the two third guide surfaces 133 may be arranged parallel to each other. In this embodiment, when the clamping portion 220 clamps the guide rail, the guide protrusion 232 may be located at the connection between the first guide surface 131 and the third guide surface 133.

[0050] More specifically, on both sides of the guiding part 130 along the third direction, fourth guiding surfaces 134 may be respectively provided. The first end of the fourth guiding surface 134 is connected to the corresponding second guiding surface 132, and the second end of the fourth guiding surface 134 is connected to the wall of the relief hole 112. Exemplarily, the two fourth guiding surfaces 134 may be arranged parallel to each other. Exemplarily, a force relief groove 135 may be provided between the second guiding surface 132 and the third guiding surface 133. Before the clamping plate 200 is clamped with the guide rail, the guiding protrusion 232 may be placed in the corresponding force relief groove 135 to reduce the bending deformation of the elastic arm 231 and effectively improve the service life of the elastic arm 231.

[0051] In this embodiment, the elastic member 230 may also be set as a spring or an elastic body with other structures, which is not limited in this application.

[0052] In this embodiment, referring to Figure 4 As shown, the sliding channel 111 is provided with a relief groove 113 for accommodating the clamping part 220; the clamping part 220 includes a convex block 221. The convex block 221 protrudes from the sliding plate part 210 along the second direction towards the bottom of the limiting groove 102. A limiting surface 2211 is provided on the convex block 221. The limiting surface 2211 is arranged on the side of the convex block 221 facing away from the second boss 120, and the limiting surface 2211 can abut against the wall of the relief groove 113 along the first direction to form a limit, preventing the sliding plate part 210 from sliding excessively away from the second boss 120 and disengaging from the sliding channel 111, and preventing the guiding protrusion 232 from abutting against the wall of the relief hole 112, thus effectively protecting the elastic member 230.

[0053] Specifically, the relief groove 113 is provided with a stop wall 1131 parallel to the limiting surface 2211. When the clamping part 220 clamps the guide rail, a gap is formed between the stop wall 1131 and the limiting surface 2211. When the stop wall 1131 abuts against the limiting surface 2211, the clamping part 220 disengages from the guide rail, and effectively prevents the sliding plate part 210 from sliding further away from the second boss 120.

[0054] Exemplarily, the wall of the relief groove 113 facing away from the bottom of the first boss 110 coincides with the bottom of the limiting groove 102, that is, the side of the clamping part 220 facing the bottom of the limiting groove 102 along the second direction abuts against the bottom of the limiting groove 102, effectively ensuring the stability of the clamping part 220 clamping the guide rail.

[0055] In this embodiment, referring to Figure 2 and Figure 4As shown, a limiting hole 114 communicating with the sliding channel 111 is provided at the bottom of the first boss 110, and a limiting protrusion 212 is provided on the sliding plate portion 210. The limiting protrusion 212 is inserted into the limiting hole 114. In this embodiment, one side of the limiting protrusion 212 facing the second boss 120 can abut against the hole wall of the limiting hole 114 to form a limit, preventing the sliding plate portion 210 from sliding excessively towards the second boss 120 and disengaging from the sliding channel 111, and preventing the guiding protrusion 232 from abutting against the hole wall of the relief hole 112, thus effectively protecting the elastic member 230.

[0056] Specifically, a second through hole 214 is provided on the sliding plate portion 210, and an extension arm 213 is provided in the second through hole 214. The first end of the extension arm 213 is connected to the first side wall of the second through hole 214 along the first direction, the second end of the extension arm 213 extends towards the second side wall of the second through hole 214 along the first direction, and a limiting protrusion 212 is provided at the second end of the extension arm 213. In this embodiment, the extension arm 213 can be bent under force to facilitate placing the limiting protrusion 212 into the limiting hole 114. In addition, by providing the extension arm 213 in the second through hole 214, the thickness of the sliding plate portion 210 can be reduced, enabling the sliding channel 111 to form a good relief with respect to the mounting groove 101.

[0057] Exemplarily, the side of the limiting protrusion 212 facing the second boss 120 is planar and perpendicular to the first direction, so that the abutment between the limiting protrusion 212 and the hole wall of the limiting hole 114 is stable and reliable.

[0058] In this embodiment, as Figure 5 shown, the sliding plate portion 210 can be inserted into the sliding channel 111 from the end of the sliding channel 111 facing the second boss 120 to complete the installation of the clamping plate 200. Exemplarily, for the convenience of installing the clamping plate 200, the side of the limiting protrusion 212 facing the second boss 120 is planar, and is inclined from the end of the limiting protrusion 212 towards the end of the sliding plate portion 210 facing away from the second boss 120.

[0059] In a feasible implementation manner, as Figure 2 and Figure 4 shown, a rib 215 extending along the first direction is provided on the sliding plate portion 210. The rib 215 abuts against the inner surface of the sliding channel 111 to reduce the contact between the sliding channel 111 and the clamping plate 200 and lower the friction therebetween, making it more convenient to slide the clamping plate 200. Exemplarily, ribs 215 are respectively provided on both sides of the sliding plate portion 210 along the third direction.

[0060] In a feasible implementation manner, as Figure 2 and Figure 5As shown, a long groove 115 is provided on the inner surface of the sliding channel 111. The long groove 115 penetrates the sliding channel 111 along the first direction to make way for the sliding plate portion 210 and reduce the contact between the sliding channel 111 and the clamping plate 200. Exemplarily, the long groove 115 may be provided on the side of the sliding channel 111 facing away from the bottom of the first boss 110. The long groove 115 provides a space for the bending of the elastic arm 231 and the extension arm 213, facilitating the installation of the clamping plate 200.

[0061] In this embodiment, with reference to Figure 3 As shown, one end of the sliding plate portion 210 facing away from the second boss 120 is provided with a pushing and pulling portion 216, and the pushing and pulling portion 216 protrudes from the sliding channel 111. In this embodiment, due to the provision of the pushing and pulling portion 216, the sliding of the sliding plate portion 210 is facilitated, that is, the disassembly and assembly of the guide rail buckle structure relative to the guide rail are facilitated.

[0062] In a feasible implementation manner, a pushing and pulling hole 217 may be provided on the pushing and pulling portion 216 to further facilitate the sliding of the sliding plate portion 210. Exemplarily, the pushing and pulling hole 217 may be a long strip hole, and an arc-shaped groove is provided at the center of the hole wall on the side facing away from the second boss 120.
