Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lamps and lanterns, in particular to a power box assembly and a guide rail lamp provided with the power box assembly and a lighting system provided with the guide rail lamp. BACKGROUND

[0002] The connecting rod of the power box assembly of the existing guide rail lamp is mostly assembled on the box body through nuts, anti-skid washers and other accessories. Figure 1 As shown in the figure, the first end of the connecting rod 91 is provided with a limiting part 911 and a stud part 912, and the bottom of the box body 92 is provided with a connecting through hole 921; when the connecting rod 91 is assembled with the box body 92, the stud part 912 is inserted into the connecting through hole 921 from the bottom of the box body 92, and then an anti-skid washer and a nut 93 are sleeved on the stud part 912 extending into the box body 92, and the nut 93 is screwed to make the limiting part 911 of the connecting rod 91 abut against the bottom of the box body 92, and the anti-skid washer abuts against the inside of the box body 92 and the nut 93, thereby fixing the connecting rod 91 on the box body 92; however, the existing assembly mode between the connecting rod 91 and the box body 92 has the following shortcomings:

[0003] Firstly, too many accessories are needed when assembling the connecting rod 91 and the box body 92, which leads to complicated assembly steps, low assembly efficiency and high cost.

[0004] Secondly, when the nut 93 is screwed too tightly, it will be difficult for the connecting rod 91 to rotate relative to the box body 92; when it is screwed too loosely, the connecting rod 91 will be easily moved relative to the box body 92 in the axial direction of the connecting rod 91; and even if an anti-skid washer is provided, the nut 93 will inevitably become looser as the number of times of adjusting the circumferential irradiation angle of the lamp head assembly of the guide rail lamp through the connecting rod 91 increases, and once the nut 93 is loosened, the entire guide rail lamp needs to be removed from the guide rail, and the upper cover of the power box assembly needs to be disassembled to tighten the nut 93, which is troublesome and inconvenient.

[0005] Thirdly, since the stud part 912 of the connecting rod 91 is inserted into the connecting through hole 921 from the bottom of the box body 92 and is supported and hoisted by the nut 93, the box body 92 does not produce any substantial support and limiting effect on the connecting rod 91; the weight of the lamp head assembly is large, and in order to ensure the installation of other components in the box body 92, the length of the stud part 912 cannot be too long, which makes the connectable length of the nut 93 and the stud part 912 short, increasing the risk of loosening of the nut 93 and disengagement of the stud part 912, which leads to the risk of the lamp head assembly dragging the connecting rod 91 to fall off the box body 92 when the nut 93 is loosened, thereby affecting the use safety and personal safety.

[0037] Power box assembly embodiment

[0038] Referring to 2 and Figure 3 The power box assembly 100 comprises a box body 1, a connecting rod 2, an upper cover 3, a wrench and a bolt 5.

[0039] In combination with Figure 4 The box body 1 has a containing cavity 11, wherein the bottom of the containing cavity 11 protrudes outwardly from the box body 1 to form a sunken boss 12, so that the sunken boss 12 is in communication with the containing cavity 11; preferably, the sunken boss 12 is located at the first end of the containing cavity 11. The bottom wall of the sunken boss 12 is provided with a connecting through hole 121, the connecting through hole 121 penetrates the bottom wall of the sunken boss 12, and the peripheral part of the connecting through hole 121 has a ring of eaves part 122.

[0040] Two or more elastic buckles 13 are formed in the sunken boss 12, and the elastic buckles 13 extend out of the containing cavity 11 from the eaves part 122. Preferably, the number of the elastic buckles 13 is between three and five, so that the cooperation between the elastic buckles 13 can effectively clamp and fix, limit the connecting rod 2, and enable the elastic buckles 13 to have the required elastic deformation capacity, while also being conducive to simplifying the structure of the box body 1, reducing the production difficulty and production cost of the box body 1, such as in this embodiment, the number of the elastic buckles 13 is four. In addition, the extending end of the elastic buckle 13 has a buckle part 131, and the buckle part 131 of each elastic buckle 13 and the eaves part 122 form a clamping position.

[0041] In combination with Figures 5 to 7, the connecting rod 2 has a rotating column portion 21, a rod portion and a circular table, wherein the circular table is connected between the bottom of the rotating column portion 21 and the first end of the rod portion, and the rotating column portion 21, the rod portion and the circular table are integrally formed. When the connecting rod 2 is assembled with the box body 1, the connecting rod 2 is inserted from the accommodating cavity 11 to the connecting through hole 121 of the sunken boss 12, until the rotating column portion 21 is clamped and fixed in the clamping position (that is, the bottom of the rotating column portion 21 is adjacent to the eave portion 122, and the buckle portion 131 of the elastic buckle 13 is buckled on the top of the rotating column portion 21), the circular table is inserted in the connecting through hole 121, and the rod portion penetrates out of the connecting through hole 121 and extends out of the box body 1, so that the rotating column portion 21 can rotate relative to the box body 1 around the axis thereof. The gap fit is preferably provided between the peripheral wall of the circular table and the inner hole wall of the connecting through hole 121; the design of the circular table is beneficial to improve the stability of the rotation of the connecting rod 2 relative to the box body 1, and is beneficial to optimize the stress of the elastic buckle 13 (further reducing the influence of the elastic buckle 13 caused by the uneven stress between the elastic buckles 13 due to the inclination trend of the connecting rod 2 caused by the weight of the lamp holder assembly), and slow down the fatigue speed of the elastic buckle 13.

[0042] Through the above-mentioned cooperation structure design between the box body 1 and the connecting rod 2, the power box assembly 100 has the following advantages:

[0043] Firstly, compared with the existing connecting structure that the connecting rod of the power box assembly is inserted into the connecting hole in the bottom of the box body, the power box assembly 100 provided by the utility model is installed from the inside of the accommodating cavity 11 of the box body 1 (that is, the connecting rod 2 is installed from the top of the box body 1 to the bottom of the box body 1), so that the sunken boss 12 on the box body 1 supports the rotating column portion 21 of the connecting rod 2 and substantially supports the rotating column portion 21 through the eave portion 122. Therefore, even if the lamp holder assembly installed on the connecting rod 2 is heavy, the connecting rod 2 and the lamp holder assembly are effectively prevented from being separated from the box body 1 under the support and limitation of the eave portion 122, thereby preventing the connecting rod 2 and the lamp holder assembly from falling, improving the safety of the power box assembly 100 and the guide rail lamp provided with the power box assembly 100, and greatly improving the carrying capacity of the power box assembly 100, so that the power box can be adapted to a wider type of lamp holder assembly.

[0044] Secondly, the elastic buckle 13 is formed on the box body 1, which better simplifies the structure of the connecting rod 2 and the box body 1, avoids the need to simultaneously provide a complex buckle structure on the box body 1 and the connecting rod 2, simplifies the structure of the connecting rod 2, and further reduces the production cost of the connecting rod 2 and the complexity of the production mold.

[0045] Thirdly, since the elastic buckle 13 is formed on the box body 1, it is also ensured that the box body 1 can substantially support the connecting rod 2; moreover, since the weight of the connecting rod 2 and the lamp holder assembly mounted thereon is supported by the eave portion 122, the elastic buckle 13 cooperates with the fixing and limiting effect thereof, thus the material performance and structural strength requirement of the elastic buckle 13 is low, which is also beneficial to reduce the production cost and production difficulty.

[0046] Fourthly, the box body 1 and the connecting rod 2 are connected through the buckle structure, which greatly reduces the number of accessories required when assembling the box body 1 and the connecting rod 2, thereby simplifying the assembly therebetween, improving the assembly efficiency, and reducing the production cost, and meanwhile, the buckle connection therebetween neither limits the rotation of the connecting rod 2 relative to the box body 1, nor causes unreasonable looseness between the two.

[0047] Fifthly, since the connecting rod 2 does not need to be provided with a limiting structure cooperating with a nut as in the prior art, the overall appearance of the power box is more simple, coordinated and beautiful.

[0048] Preferably, the rotating column portion 21 of the connecting rod 2 has an annular groove 211 in the axial direction, and at least a portion of the elastic buckle 13 is formed with a first protrusion 132 at the annular groove 211; more preferably, each elastic buckle 13 is formed with a first protrusion 132 at the annular groove 211. When the box body 1 and the connecting rod 2 are assembled, the first protrusion 132 is clamped in the annular groove 211. The first protrusion 132 can preferably be in the shape of an arcuate strip (see Figure 4 ), a hemisphere or a spherical cap; wherein the generatrix of the first protrusion 132 in the shape of an arcuate strip and the generatrix of the annular groove 211 are both in the shape of a circular arc. This design is beneficial to further prevent the connection between the box body 1 and the connecting rod 2 from being loose in an unreasonable manner; meanwhile, under the cooperation of the above structure, the damping effect when the connecting rod 2 rotates relative to the box body 1 can be increased, so as to better prevent the connecting rod 2 from rotating relative to the box body 1 after the angle adjustment is completed, thereby ensuring the accuracy and stability of the adjustment angle of the connecting rod 2 and the lamp holder assembly thereon. Of course, as another alternative, in other embodiments, the above structure (annular groove 211, first protrusion 132) can also be designed as follows: an annular protrusion is formed in the circumferential direction of the rotating column portion 21, and an arcuate groove cooperating with the annular protrusion is formed on each elastic buckle 13, so that when the box body 1 and the connecting rod 2 are assembled, the annular protrusion is clamped in the arcuate groove; wherein the generatrix of the annular protrusion and the generatrix of the arcuate groove are both in the shape of a circular arc.

[0049] In addition, in order to limit the rotation angle of the connecting rod 2 relative to the box body 1, so as to avoid the cable connected to the lamp head assembly from being damaged due to excessive torsion, a first limiting portion 123 is formed on the side of the eave portion 122 facing the accommodating cavity 11, and correspondingly, a second limiting portion 212 is formed on the bottom of the rotating column portion 21 of the connecting rod 2, the second limiting portion 212 can rotate with the connecting rod 2 to abut against the first limiting portion 123, thereby limiting the rotation of the connecting rod 2 relative to the box body 1; preferably, the rotation angle between the connecting rod 2 and the box body 1 is between 0° and 355°, so as to maximize the rotatable angle of the connecting rod 2, and thus maximize the lighting range of the lamp head assembly connected to the connecting rod 2. It can be seen that the cooperation of the first limiting portion 123 and the second limiting portion 212 can protect the cable.

[0050] Further, a plurality of clamping grooves 124 are formed on the side of the eave portion 122 facing the accommodating cavity 11, the plurality of clamping grooves 124 are distributed along the circumferential direction of the connecting through hole 121, and preferably, adjacent two clamping grooves 124 are closely adjacent; correspondingly, in this embodiment, the bottom of the rotating column portion 21 is provided with a spring plunger 213, and the positioning column of the spring plunger 213 is arranged towards the clamping grooves 124, so that the positioning bead 2131 of the spring plunger 213 can be clamped with any clamping groove 124. This design can appropriately increase the damping feeling when the connecting rod 2 rotates relative to the box body 1, and at the same time, when the positioning bead 2131 of the spring plunger 213 passes through the currently matched clamping groove 124 and switches to the next clamping groove 124, a click sound is generated, so as to improve the user's experience of adjusting the hand feeling and listening feeling. It should be noted that as another optional solution, in other embodiments, a second protrusion can be formed on the bottom of the rotating column portion 21 instead of the spring plunger 213, that is, in this solution, the second protrusion can be clamped with any clamping groove 124; wherein the second protrusion is preferably hemispherical or spherical crown.

[0051] Further, a wire channel is formed in the connecting rod 2, the wire channel penetrates through the connecting rod 2, and the wire channel is used for the cable connected between the power supply module arranged in the box body 1 and the light source in the lamp head assembly connected to the connecting rod 2 to pass through, thereby hiding the cable in the power supply box assembly 100, so as to improve the aesthetics of the rail light provided with the power supply box assembly 100. In addition, the second end of the rod portion of the connecting rod 2 is preferably provided with a stop portion, the stop portion is used for the cooperation of the lamp head assembly, and the lamp head assembly can be limited in the vertical position, thereby ensuring the lighting effect when the lamp head assembly performs vertical lighting.

[0052] The upper cover 3 covers the opening of the accommodating cavity 11 of the box body 1 to prevent the power supply module arranged in the box body 1 from being contaminated by dust, wherein the opening of the accommodating cavity 11 is formed on the top of the box body 1. The upper cover 3 has an insertion part 31 and a cover part 32, the cover part 32 is connected with the box body 1, and the insertion part 31 is used for rail fitting connection, and the cover part 32 covers the opening of the accommodating cavity 11.

[0053] One of the cover part 32 of the upper cover 3 and the wall part of the accommodating cavity 11 is provided with a buckle part 111, and the other is provided with a clamping groove 322, as in the embodiment, the cover part 32 is formed with the clamping groove 322, and the wall part of the accommodating cavity 11 is formed with the buckle part 111, when the upper cover 3 is assembled with the box body 1, the buckle part 111 is clamped in the clamping groove 322; and / or, the accommodating cavity 11 is provided with a connecting column 112, the upper cover 3 has a mounting through hole 321, and the power supply box assembly 100 further comprises a bolt 5, when the upper cover 3 is assembled with the box body 1, the bolt 5 is connected with the connecting column 112 after passing through the mounting through hole 321. In the embodiment, the upper cover 3 is simultaneously formed with the clamping groove 322 and the mounting through hole 321, and the box body 1 is simultaneously formed with the buckle part 111 and the connecting column 112; the composite connection structure of the clamping structure and the threaded connection structure is used to connect the upper cover 3 and the box body 1, so that the firmness and reliability of the connection of the two can be ensured, and at the same time, the disassembly of the two is relatively simple.

[0054] The rotating wrench 4 is rotatably connected with the upper cover 3, and the rotating wrench 4 is provided with a conductive sheet group 42, so that the conductive sheet group 42 can rotate with the rotating wrench 4 to extend out of the insertion part 31, and then be electrically connected with the corresponding conductive copper strip in the rail, so that the rail supplies power to the power supply box assembly 100. Preferably, the rotating wrench 4 and the connecting through hole 121 are located at one end of the box body 1, which can better optimize the internal space of the box body 1 to ensure that the power supply module can be installed in the box body 1, and is also conducive to reducing the volume of the power supply box assembly 100 and saving production cost.

[0055] In addition, the box body 1 is provided with a avoiding opening 113 at the rotating wrench 4, and the wrench part 41 of the rotating wrench 4 extends out of the box body 1 through the avoiding opening 113; further, the avoiding opening 113 is provided with two limiting blocks 1131, and the two limiting blocks 1131 are respectively used for limiting the rotating wrench 4 at the unlocking position and the locking position; when the rotating wrench 4 is at the unlocking position, the conductive sheet group 42 thereon is disconnected from the electrically conductive copper strip in the rail, so that the power supply box assembly 100 can be removed from the rail; when the rotating wrench 4 is at the locking position, the conductive sheet group 42 thereon extends to the insertion part 31 of the upper cover 3 and is electrically connected with the conductive copper strip in the rail, so that the rail supplies power to the power supply box assembly 100.

[0056] Further, the insertion part 31 is further provided with an elastic pressing buckle 311 at the end far from the rotating wrench 4, the fixed end of the elastic pressing buckle 311 is located at the top of the insertion part 31, the free end of the elastic pressing buckle 311 is arranged close to the cover part 32, the claw part of the elastic pressing buckle 311 is used for guide rail cooperation connection, and the elastic pressing buckle 311 is used for improving the firmness and reliability of the connection between the power box assembly 100 and the guide rail.
