Utility Model Content

[0004] The main purpose of the utility model is to provide a plug-in installation structure for a guide rail and an electrical box, aiming to solve the technical problems of low reliability or complex structure of the installation structure of the guide rail lamp in the prior art.

[0005] To achieve the above purpose, the utility model proposes a plug-in installation structure of a guide rail and an electrical box, comprising:

[0008] The guide rail has a transversely arranged insertion opening and a slot, and a transversely arranged plug-in component is arranged on the upper side of the electrical box. When installing the electrical box and the guide rail, the plug-in component of the electrical box is passed transversely through the insertion opening and the insertion slot, and the power connection piece on the plug board is in contact with the conductive strip in the guide rail for conduction. At this time, the plug-in component is between the upper rail portion and the lower rail portion, the lower rail portion supports the plug board, and the box body is on the lower side of the guide rail, so that the electrical box is installed on the guide rail, the structure is simple, and the installation is easy. In addition, because the lower rail portion supports the plug board, the guide rail and the plug board have a large contact force area, and the separation direction of the electrical box and the guide rail is basically perpendicular to the force direction, the weight of the electrical box will not cause the electrical box to separate from the guide rail, which can greatly improve the reliability of the installation of the electrical box and the guide rail.

[0009] Preferably, in the installed state, the upper rail portion and the lower rail portion clamp the plug-in assembly up and down.

[0010] The upper rail and the lower rail clamp the plug assembly, which can increase the contact with the plug board and the power connection piece, increase the difficulty of the plug assembly to leave the track, and keep the electrical box and the guide rail relatively fixed to reduce the shaking of the electrical box. In addition, it can also improve the tightness of the contact between the power connection piece and the conductive strip.

[0011] Preferably, a snap-in groove is further provided between the upper rail portion and the lower rail portion, the snap-in groove is provided on the left side of the slot and is connected to the slot, the height of the slot is smaller than the height of the snap-in groove, a snap-in protrusion which can enter the snap-in groove and snap-in with the left side of the slot is provided on the left side of the plug board, an insertion guide inclined surface is provided on the left side of the plug board, and the insertion guide inclined surface is provided on the left side of the snap-in protrusion.

Moreover, after the plug-in board is inserted into the slot, it will deform upward and generate an upward elastic force on the box body, reduce the downward sagging of the electrical box, reduce the gap between the electrical box and the guide rail, and make the appearance more beautiful.

[0043] like Figures 1 to 11 As shown, a plug-in installation structure of a guide rail and an electrical box comprises a guide rail 1 and an electrical box 2.

[0044] The guide rail 1 includes an upper rail portion 11 and a lower rail portion 12 located at the lower side of the upper rail portion 11. The upper rail portion 11 and the lower rail portion 12 are connected at their left sides. Specifically, the upper rail portion 11 and the lower rail portion 12 are connected at their left sides through a rail riser 17. A slot 13 is provided between the upper rail portion 11 and the lower rail portion 12. An insertion opening 131 is provided at the right side of the slot 13. A conductive strip is provided at the lower side of the upper rail portion 11 and / or the upper side of the lower rail portion 12. The guide rail 1 can be fixed to a wall or ceiling lamp.

[0045] The electrical box 2 includes a box body 3 and a plug assembly, the plug assembly includes a plug board 4 and an electrical connection piece, the plug board 4 is transversely arranged on the upper side of the box body 3, the right side of the plug board 4 is fixedly connected to the box body 3, the lower side of the plug board 4 is spaced apart from the upper side of the box body 3, the electrical connection piece is arranged on the plug board 4, the electrical connection piece can contact with the conductive strip, the plug assembly can pass through the insertion opening 131 from right to left and be inserted into the slot 13 to realize the installation state of the guide rail 1 and the electrical box 2, in the installation state, the lower rail part 12 is arranged between the plug board 4 and the box body 3 and supports the plug board 4, and the electrical connection piece is in contact with the conductive strip for conduction. A circuit board can be arranged in the box body 3, the circuit board is electrically connected to the electrical connection piece, and a light source or a plug can be arranged on the lower side of the box body 3 to form a guide rail 1 lamp or a socket, etc. according to the use requirements.

[0046] The guide rail 1 has a transverse insertion opening 131 and a slot 13, and a transverse plug-in assembly is arranged on the upper side of the electrical box 2. Figure 1 and Figure 5When installing the electrical box 2 and the guide rail 1, the plug assembly of the electrical box 2 is inserted horizontally through the insertion opening 131 and the insertion slot 13, and the electrical connection piece on the plug board 4 is in contact with the conductive strip in the guide rail 1. At this time, the plug assembly is between the upper rail portion 11 and the lower rail portion 12, the lower rail portion 12 supports the plug board 4, and the box body 3 is on the lower side of the guide rail 1, so that the electrical box 2 is installed on the guide rail 1. Figure 2 The structure is simple and the installation is easy. In addition, since the lower rail portion 12 supports the plug board 4, the guide rail 1 and the plug board 4 have a large contact force area, and the separation direction of the electrical box 2 and the guide rail 1 is basically perpendicular to the force direction. The weight of the electrical box 2 will not cause the electrical box 2 to separate from the guide rail 1, which can greatly improve the reliability of the installation of the electrical box 2 and the guide rail 1.

[0047] In some specific embodiments, the upper rail portion 11 and the lower rail portion 12 clamp the plug-in assembly upward and downward in the installed state.

[0048] The upper rail portion 11 and the lower rail portion 12 clamp the plug assembly, which can increase the contact with the plug board 4 and the power connection piece, increase the difficulty of the plug assembly to get off the track, and keep the electrical box 2 and the guide rail 1 relatively fixed to reduce the shaking of the electrical box 2, and also improve the tightness of the contact between the power connection piece and the conductive strip. The upper rail portion 11 and the lower rail portion 12 clamp the plug assembly, which can be understood as the upper rail portion 11 and the lower rail portion 12 clamp the upper side and the lower side of the plug board 4 respectively, or at least clamp through the position of the power connection piece.

[0049] Furthermore, a snap-in groove 14 is provided between the upper rail portion 11 and the lower rail portion 12. The snap-in groove 14 is provided on the left side of the slot 13 and is connected to the slot 13. The height h1 of the slot 13 is less than the height h2 of the snap-in groove 14. A snap-in protrusion 41 that can enter the snap-in groove 14 and snap-in with the left side of the slot 13 is provided on the left side of the plugboard 4. An insertion guide bevel 42 is provided on the left side of the plugboard 4. The insertion guide bevel 42 is provided on the left side of the snap-in protrusion 41.

[0050] The plug board 4 is first inserted into the insertion opening 131 through the insertion guide bevel 42. The insertion guide bevel 42 can squeeze the insertion opening 131 and the slot 13, that is, the upper rail portion 11 and the lower rail portion 12 are stretched open. The guide rail 1 is made of aluminum or plastic material and has a certain elasticity. When the clamping protrusion 41 reaches the clamping groove 14, the upper rail portion 11 and the lower rail portion 12 will rebound to approach each other and clamp the plug assembly. The insertion guide bevel 42 can facilitate the insertion of the plug board 4 into the insertion opening 131. Moreover, when the clamping protrusion 41 enters the clamping groove 14, since the height h1 of the slot 13 is less than the height h2 of the clamping groove 14, the clamping protrusion 41 and the end of the slot 13 are not easily disengaged, thereby improving the reliability of the installation of the electrical box 2 and the guide rail 1. Preferably, the clamping protrusion 41 is located at the lower side of the plug board 4, and the insertion guide bevel 42 is provided on the left side of the clamping protrusion 41. The insertion guide bevel 42 can also be provided on the upper side of the plug board 4.

[0051] Furthermore, a withdrawal guiding inclined surface 43 is provided on the right side of the engaging protrusion 41 , and the inclination of the withdrawal guiding inclined surface 43 is greater than the inclination of the insertion guiding inclined surface 42 .

[0052] When the electrical box 2 needs to be removed, the electrical box 2 can be pulled out to the right with force, and the guide inclined surface 43 can squeeze the slot 13 when pulling out, making it easy to remove. The inclination of the pull-out guide inclined surface 43 is greater than the inclination of the insertion guide inclined surface 42. Compared with the insertion, a greater force is required to squeeze the slot 13 when pulling out, so that the clamping installation is not easy to fall out at the clamping protrusion 41, and it can also be pulled out with force when disassembling.

[0053] The angle of the insert plate 4 can be set in a variety of ways, at least as shown in the following embodiments 1 and 2.

[0054] Embodiment 1:

[0055] Reference Figure 1 , Figure 2 and Figure 4 , the insert plate 4 is arranged horizontally.

[0056] Embodiment 2:

[0057] Reference Figure 5 and Fig.10 The inserting plate 4 is tilted downward from right to left, and the left end of the inserting plate 4 is tilted upward.

[0058] After the plug board 4 is inserted into the slot 13, since the plug board 4 is tilted downward, the plug board 4 can press the lower rail portion 12 downward, increase the clamping force of the upper rail portion 11 and the lower rail portion 12 on the plug assembly, and increase the stability of the connection with the guide rail 1. Moreover, after the plug board 4 is inserted into the slot 13, it will deform upward and generate an upward elastic force on the box body 3, reduce the downward sagging of the electrical box 2, and reduce the gap between the electrical box 2 and the guide rail 1, making the appearance more beautiful. Moreover, when the conductive strip is located at the lower side of the upper rail portion 11, the position of the power connection piece can be close to the upper side and contact with the conductive strip, avoiding the lower rail portion 12 being deformed downward due to the weight of the electrical box 2, resulting in poor contact between the power connection piece located on the upper side and the conductive strip. Since the plug board 4 is tilted downward, the left end of the plug board 4 is set to tilt upward, so that the left end of the plug board 4 can be basically kept at the same height as the insertion opening 131, so that the plug board 4 can be inserted into the insertion opening 131. Preferably, the size of the angle α between the plug board 4 and the vertical direction is 82°≤α<90°.

[0059] Furthermore, the lower side of the left end of the plug board 4 is an arc surface, which facilitates the plug board 4 to smoothly contact with the lower rail portion 12 and deform the plug board 4 upward when inserted into the slot 13 . The arc surface is the insertion guide inclined surface 42 .

[0060] In some specific embodiments, referring to Figures 8 to 10The plug board 4 is provided with a spring piece 44 that can swing up and down, and the lower side of the spring piece 44 protrudes toward the lower side of the plug board 4. In the installed state, the lower side of the spring piece 44 can abut against the upper side of the lower rail portion 12.

[0061] In order to prevent the guide rail 1 from being too rigid, resulting in insufficient elasticity and thus insufficient clamping force on the plug board 4, a spring sheet 44 is provided on the plug board 4, and the lower side of the spring sheet 44 abuts against the upper side of the lower rail portion 12. After being squeezed by the lower rail portion 12, the spring sheet 44 deforms upward to generate auxiliary elastic force, which can increase the clamping force of the upper rail portion 11 and the lower rail portion 12 on the plug board 4.

[0062] Furthermore, the upper side of the spring sheet 44 is recessed in the upper side of the plug board 4, so that when the spring sheet 44 is deformed upward, there is space for it to move upward, thereby preventing the upper rail portion 11 from pressing against the upper side of the spring sheet 44 and preventing it from deforming.

[0063] In some specific embodiments, in the installed state, the upper side surface of the box body 3 abuts against the lower side surface of the lower rail portion 12 .

[0064] In this way, the contact area between the electrical box 2 and the guide rail 1 can be increased, the stability of the connection between the electrical box 2 and the guide rail 1 can be improved, the shaking of the electrical box 2 can be reduced, and the gap between the electrical box 2 and the guide rail 1 can be reduced.

[0065] In some specific embodiments, referring to Figure 3 Conductive strips are provided on the lower side of the upper rail portion 11 and the upper side of the lower rail portion 12, the conductive strip provided on the lower side of the upper rail portion 11 is the upper conductive strip 15, and the conductive strip provided on the upper side of the lower rail portion 12 is the lower conductive strip 16; at least two electrical connections are provided on the plug board 4, the at least two electrical connections are respectively an upper electrical connection 5 and a lower electrical connection 6, the upper electrical connection 5 and the lower electrical connection 6 are arranged along the length direction of the guide rail 1, the upper electrical connection 5 is provided with an upper electrical connection protrusion 51 protruding from the upper side of the plug board 4, the lower electrical connection 6 is provided with a lower electrical connection protrusion 61 protruding from the lower side of the plug board 4, the upper electrical connection protrusion 51 can contact with the upper conductive strip 15, and the lower electrical connection protrusion 61 can contact with the lower conductive strip 16.

[0066] The upper conductive strips 15 and the lower conductive strips 16 arranged up and down can reduce the short circuit of the positive and negative poles. If the shape of the spliced ​​guide rail is more complicated, such as the overall shape of the spliced ​​guide rail is in the shape of a field, the upper conductive strips 15 and the lower conductive strips 16 arranged horizontally are easily staggered, resulting in wiring errors and short circuits. The upper conductive strips and the lower conductive strips in the guide rail of this scheme will not be staggered up and down; in addition, if the structure of two conductive strips arranged horizontally is adopted, it may occur that during the insertion or removal of the plug assembly, a power connection piece contacts the two conductive strips at the same time, causing a short circuit. The upper conductive strips 15 and the lower conductive strips 16 arranged up and down can reduce the width of the guide rail 1. The upper power connection protrusion 51 and the lower power connection protrusion 61 can form a certain elasticity by using the power connection piece, so as to maintain contact with the upper conductive strip 15 and the lower conductive strip 16. In other embodiments, the two conductive strips can be arranged only on the lower rail portion 12 or only on the upper rail portion 11, and the number of conductive strips and power connections can also be increased according to actual needs.

[0067] Furthermore, the upper rail portion 11 includes an upper plate 111, and a left upper vertical plate 112 and a right upper vertical plate 113 are arranged at intervals on the lower side of the upper plate 111, and an upper conductive strip 15 is arranged between the left upper vertical plate 112 and the right upper vertical plate 113. The upper side of the upper conductive strip 15 can be insulated by a co-extruded plastic strip, and the lower side of the upper conductive strip 15 is substantially flush with the lower sides of the left upper vertical plate 112 and the right upper vertical plate 113; the lower rail portion 12 includes a lower plate 121, and the lower plate 12 1 is provided with a left lower vertical plate 122 and a right lower vertical plate 123 spaced apart from each other on the upper side, a lower conductive strip 16 is provided between the left lower vertical plate 122 and the right lower vertical plate 123, the lower side of the lower conductive strip 16 can be insulated by a co-extruded plastic strip, the upper side surface of the lower conductive strip 16 is substantially flush with the upper sides of the left lower vertical plate 122 and the right lower vertical plate 123, and the slot 13 is provided between the left upper vertical plate 112 and the right upper vertical plate 113 and the left lower vertical plate 122 and the right lower vertical plate 123.
