[0032] The present invention is further described below through specific implementation methods.

[0033] The terms "first" and "second" appearing in the present invention are only for the convenience of description to distinguish different components with the same name, and do not indicate a sequence or primary and secondary relationship.

[0034] In the description of the present invention, the directions or positional relationships indicated by “up”, “down”, “left”, “right”, “front” and “back” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention. They do not indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0035] In this application, unless otherwise specified, "plurality" refers to two or more. "And / or" describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0036] See also Figures 1 to 8A guide rail mounting device includes a base 10 and a locking block 20. The base 10 is provided with a guide rail groove 11 for receiving a guide rail 30, and the base serves as the base of a relay module. The guide rail groove 11 is provided with a first side wall 12 and a second side wall 13 opposing each other, and a bottom surface. The first side wall 12 and the second side wall 13 are located on either side of the bottom surface, and the other sides and the top side of the guide rail groove 11 are configured to pass through the guide rail groove 11. The first side wall 12 is provided with a first clip 14 for snapping onto one side of the guide rail 30. The locking block 20 is movably mounted on the base 10 and provided with a second clip 21. The second clip 21 is located on the second side wall 13. Movement of the locking block 20 allows the second clip 21 to snap onto or detach from the other side of the guide rail 30. A first inclined surface 15 is provided on the side of the first clip 14 opposite to the bottom surface of the guide rail groove 11, and a card slot 14a is formed between the first inclined surface 15 and the bottom surface of the guide rail groove 11. The top surface of the card slot 14a has the first inclined surface 15, which facilitates the inclined insertion or removal of one side of the guide rail 30 from the card slot 14a.

[0037] Among them, the first clip 14 and the second clip 21 are structures that protrude relative to the side wall of the guide rail groove 11, and the first clip 14 and the second clip 21 extend relative to each other. The first inclined surface 15 extends obliquely from the end of the first side wall 12 of the first clip 14 in the direction away from the bottom surface of the guide rail groove 11 to the end of the first clip 14 opposite to the second side wall 13. There is an angle θ between the first inclined surface 15 and the bottom surface of the guide rail groove 11. The angle θ is an acute angle. The specific angle range can be set according to actual conditions and is not limited here. In addition, since the guide rail 30 can be inserted into the slot 14a or removed from the slot 14a at an angle, the size of the first clip 14 in the direction perpendicular to the first side wall 12 can be set smaller. That is, the size of the first clip 14 in the direction perpendicular to the first side wall 12 is smaller than the maximum size of the first clip 14 in the direction perpendicular to the guide rail groove 11, making the first clip 14 shorter and thicker, thereby improving strength.

[0038] In the present invention, the size of the slot 14a can also be increased, that is, the minimum distance L between the bottom surface of the guide rail groove 11 and the corresponding surface of the first latch 14, namely the first inclined surface 15, is set to be greater than the thickness of the corresponding side of the guide rail groove 11, so as to meet the requirements of disassembly and assembly of guide rails 30 of different thicknesses. Because the size of the slot 14a is greater than the thickness of the guide rail 30, in order to better fix the guide rail 30 to the guide rail groove 11, a protrusion 16 is provided on the bottom surface of the guide rail groove 11. The protrusion 16 can be located near the first side wall 12, and there is a gap between the protrusion 16 and the projection of the first latch 14 on the bottom surface of the guide rail groove 11. That is, there is a gap between the protrusion 16 and the first latch 14 in the direction perpendicular to the first side wall 12, and there is also a gap between the protrusion and the first latch 14 in the height direction of the guide rail groove 11. After the side of the guide rail groove 11 is inserted into the slot 14a, the convex bump 16 pushes up the guide rail 30 to deform it, and cooperates with the slot 14a to fix the guide rail 30 relative to the guide rail groove 11. The height H of the convex bump 16 can be set according to needs.

[0039] In practical applications, the present invention includes one or more first clips 14. If there is only one first clip 14, the first clip 14 can be larger along the length of the first side wall 12. If there are multiple first clips 14, the first clip 14 can be smaller along the length of the first side wall 12. The multiple first clips 14 are spaced apart along the length of the first side wall 12, and the sizes and shapes of the multiple first clips 14 can be the same or different. The present invention also includes one or more protrusions 16. If there are multiple protrusions 16, the multiple protrusions 16 are spaced apart along the length of the first side wall 12. The positions of the multiple protrusions 16 and the multiple first clips 14 can correspond one-to-one or not, depending on the actual situation.

[0040] Furthermore, the convex 16 is provided with a second inclined surface 17, which is located on the side of the convex 16 opposite to the first buckle. The second inclined surface 17 is opposite to the first inclined surface 15, and the inclination direction of the second inclined surface 17 can be the same as that of the first inclined surface 15. The second inclined surface 17 is provided to facilitate the insertion or removal of one side of the guide rail 30. Figure 4 The second inclined surface 17 extends obliquely from the end of the convex 16 where the bottom surface of the guide groove 11 is located toward a direction away from the bottom surface of the guide groove 11 to the end of the convex 16 away from the bottom surface of the guide groove 11.

[0041] The base 10 of the present invention is provided with a mounting groove 13a on one side near the second side wall 13. The mounting groove 13a is connected to the guide rail groove 11 and has a notch 13b on the second side wall 13. A locking block 20 is removably mounted in the mounting groove 13a, and a second latch 21 extends through the notch 13b. The size of the notch 13b is adapted to the size of the second latch 21. The upper surface of the second latch 21 may be provided with an inclined surface as needed. When the locking block 20 moves relative to the mounting groove 13a under the action of an external force, the second latch 21 extends outward from the mounting groove 13a or retracts into the mounting groove 13a relative to the notch 13b. When the second latch 21 extends outward from the mounting groove 13a, it latches onto the corresponding side of the guide rail 30. When the second latch 21 retracts into the mounting groove 13a, it facilitates the insertion or removal of the corresponding side of the guide rail 30.

[0042] To enable the locking block 20 to move relative to the mounting slot 13a, a positioning hole 13c is defined in the mounting slot 13a. The locking block 20 is provided with an elastically deformable portion 24, which is equipped with a positioning post 22 that is inserted into the positioning hole 13c. When the locking block 20 moves into the mounting slot 13a under the action of an external force, the elastically deformable portion 24 deforms. When the external force is removed, the elastically deformable portion 24 returns to its original position, forcing the second latch 21 to extend out of the mounting slot 13a.

[0043] In practice, the locking block 20 is provided with a window 23, which is used to connect to the elastically deformable portion 24 and provide a deformation space. The elastically deformable portion 24 is provided with two connected arcuate connecting arms 25. The ends of the two arcuate connecting arms 25 are respectively connected to the inner wall of the window 23. The positioning portion is located at the connecting end of the two arcuate connecting arms 25. The shape of the arcuate connecting arms 25 can be V-shaped, S-shaped, U-shaped, etc., and can be set according to actual conditions.

[0044] To ensure smoother and more reliable movement of the locking block 20, guide grooves 19 are provided on opposite side walls of the mounting groove 13a. The guide grooves 19 are perpendicular to the second side wall 13. Protrusions 26 are provided on either side of the locking block 20. The protrusions 26 slide in conjunction with the guide grooves 19, allowing the locking block 20 to move perpendicular to the second side wall 13. Limiting surfaces 18 are also provided on opposite side walls of the mounting groove 13a. The limiting surfaces 18 are located on the side of the guide groove 19 away from the second side wall 13 and are perpendicular to the bottom surface of the mounting groove 13a. Stops 27 are provided on either side of the locking block 20. The stoppers 27 are located on the end of the protrusions 26 away from the second buckle 21 and are perpendicular to the protrusions 26. The stoppers 27 and the limiting surfaces 18 are provided to limit the range of movement of the locking block 20, preventing the second buckle 21 from extending too far.

[0045] In the present invention, when the guide rail 30 is installed, see Figure 7 , insert one side of the guide rail 30 obliquely into the slot 14a on the side where the first clip 14 is located, and then press the other side of the guide rail 30 downward on the inclined surface of the second clip 21 (or manually operate the locking block 20 to move), so that the second clip 21 is pushed back relative to the notch 13b. After the other side of the guide rail 30 is placed in the guide rail groove 11, the external force acting on the second clip 21 disappears, and the second clip 21 returns to its original position, that is, extends outward from the installation groove 13a and buckles on the corresponding side of the guide rail 30. With the action of the convex bump 16, the guide rail 30 is fixed on the guide rail groove 11. Figure 8 、 Figure 9 .

[0046] When disassembling the guide rail 30, the locking block 20 is manipulated to move so that the second clip 21 is pushed back relative to the notch 13b, and this side of the guide rail 30 is removed from the guide rail groove 11. Then, the corresponding side of the guide rail 30 located in the slot 14a of the first clip 14 is removed to remove the guide rail 30 from the guide rail groove 11.

[0047] The structure of the present invention has a large rotation and tilting angle when the guide rail 30 is disassembled and assembled, and is easy to install or remove. The side of the guide rail 30 will not be stuck by the first clip 14, and the first clip 14 will not be broken due to the torque caused by the jamming of the guide rail 30.

[0048] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
