Description

Technical Field

[0001] The invention relates to the technical field of lighting, and in particular to a waterproof power-taking track with retractable conducting wires. Background Art

[0002] Power rails are frequently used in supermarket shelves, shopping malls and other places, but the length of the internal wires of the existing power rails is fixed and the length cannot be adjusted according to the distance of the actual position to be illuminated on the shelf.

[0003] When the internal wires of the power rail are too short and the distance to be illuminated is long, external wires are required to power the entire shelf, which is not only unsightly but also easily creates safety hazards. When the internal wires of the power rail are too long and the actual distance to the shelf to be illuminated is short, part of the power rail will not be utilized, resulting in a waste of resources.

[0004] At the same time, the existing power rails have poor waterproof performance and are easily affected by moisture, which affects their performance. Summary of the invention

[0005] In view of the above problems, an object of the present invention is to provide a waterproof power rail with a retractable conductor, the length of which can be adjusted according to actual needs and good waterproof performance.

[0006] In order to achieve the above object, the technical solution of the present invention is: a waterproof power-taking track with retractable conductors, comprising:

[0007] Base plate, plug;

[0008] A panel covering the bottom plate and enclosing the bottom plate to form a cavity;

[0009] A conductor buried in the cavity;

[0010] Features:

[0011] The panel is provided with a slide groove formed along the length direction of the cavity;

[0012] The power rail also includes an adjustment mechanism located in the cavity and connected to the wire assembly, and an output head with a lower end located in the cavity and an upper end extending out of the panel through the slide slot, and the plug is connected to the upper end of the output head;

[0013] The output head is fixedly connected to the free end of the wire and can be pulled along the direction of the slide slot in cooperation with the adjustment mechanism to drive the wire to slide on the adjustment mechanism to achieve adjustable length in the direction of the slide slot.

[0014] Furthermore, the adjustment mechanism includes a spring and a moving part which can move along the pulling direction of the output head under the drive of the output head;

[0015] The spring is arranged along the length direction of the cavity and one end is fixed to the inside of the cavity and the other end is connected to the moving part;

[0016] The fixed end of the wire is fixed in the cavity and the free end is connected to the output head after passing the moving part. The wire can slide around the moving part when the output head is pulled, and the wire length on the free end side becomes longer and the wire length on the fixed end side becomes shorter under the movement of the moving part.

[0017] Furthermore, the lower end surface of the output head is in frictional contact with the inner wall of the bottom plate, and the friction force generated by the friction is greater than the resilience of the spring, so that the output head can be positioned in the slide groove.

[0018] Furthermore, when the length of the wire on one side of the fixed end is shortened to zero, the moving part abuts against the fixed end of the wire.

[0019] Furthermore, the length of the slide groove is equal to N times the maximum distance between the moving part and the fixed end of the wire, and the value of N is 0<N≤2.

[0020] Furthermore, when the output head is located at the end of the slide slot close to the one end of the spring, the spring is in a stretched state.

[0021] Furthermore, the wires have two, namely a positive wire and a negative wire, and the surface of the moving part has two arc grooves arranged in concentric circles;

[0022] The positive electrode wire fixed end and the negative electrode wire fixed end are fixed on the bottom plate through a fixing block, and the free ends are connected to the output head after passing through the corresponding arc grooves and can slide in the arc grooves.

[0023] Furthermore, the power rail also includes an input end cover located at the end of the cavity and extending into the cavity, and a DC head is provided on the input end cover, and the DC head separates a positive input line and a negative input line;

[0024] When the positive electrode input line and the negative electrode input line extend to the fixing block, they are divided into two paths, one of which forms the positive electrode wire and the negative electrode wire, and the other continues to extend along the length direction of the cavity after passing through the fixing block to form the next positive electrode input line and the negative electrode input line;

[0025] The panel is correspondingly provided with a plurality of slide grooves distributed in series along the length direction of the cavity.

[0026] Furthermore, the bottom plate is provided with a slide rail arranged along the length direction of the cavity, and the lower end surface of the moving part and the lower end surface of the output head are respectively formed with a slide groove suitable for sliding on the slide rail.

[0027] Furthermore, the bottom plate is also provided with a steel wire arranged along the length direction of the cavity, and the input end cover and the fixing block are respectively fixedly connected to the steel wire.

[0028] Compared with the prior art, the advantages of the present invention are: a moving part is arranged inside the power-taking track, and the free end of the wire is connected to the output head after bypassing the moving part. The output head can slide in the slide groove of the panel, and the moving part is driven to move in the same direction by pulling the output head, thereby driving one side of the free end of the wire to slide and extend on the moving part while the fixed end side becomes shorter, thereby well realizing the adjustable length of the wire of the power-taking track and improving the applicability of the power-taking track; the fixed block is arranged at the position where the wire forms a branch, which can well prevent the branch from being invaded by soda and water, and has a waterproof function.

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] like Figures 1 to 3 The schematic diagram of the structure of the waterproof power rail with retractable wires of the present invention is shown. The power rail includes a base plate 1, a plug 2, a panel 3 covering the base plate 1 and enclosing the base plate 1 to form a cavity 10, and a wire 4 buried in the cavity 10. In addition to the above structure, the power rail also includes other structures, such as a mounting frame, a mains power head, etc., but since these are not the focus of protection of this application and are known to those skilled in the art, they will not be discussed in detail here, and only the protection points of this application will be described below.

[0034] In order to achieve adjustable length of the wire and adapt to different lighting length requirements, a slide groove 31 formed along the length direction of the cavity 10 is provided on the panel 3 of the power rail. The power rail also includes an adjustment mechanism 5 located in the cavity 10 and assembled with the wire 4, and an output head 6 whose lower end is located in the cavity 10 and whose upper end extends out of the panel 3 through the slide groove 31. The output head 6 is fixedly connected to the free end of the wire 4 and can be pulled along the direction of the slide groove 31 with the cooperation of the adjustment mechanism 5. This movement can drive the wire 4 to slide on the adjustment mechanism 5 to achieve adjustable length in the direction of the slide groove 31. Obviously, the change in the position of the output head 6 means a change in the length of the wire 4.

[0035] At the same time, it is easy to imagine that, in order to facilitate the subsequent assembly and connection with the lighting device, the output head 6 is most suitable for external power output, so the aforementioned plug 2 is naturally arranged on the upper end of the output head 6.

[0036] Specific to this application, Figure 2-3 As shown, the adjustment mechanism 5 includes a spring 51 and a moving member 52 which can move along the pulling direction of the output head 6 under the drive of the output head 6. The spring 51 is arranged along the length direction of the cavity 10 and one end is fixed to the end of the cavity 10 and the other end is connected to the moving member 52. The fixed end of the wire 4 is fixed in the cavity 10 and the free end is connected to the output head 6 after bypassing the moving member 52. The wire 4 can slide around the moving member 52 when the output head 6 is pulled, and the length of the wire on the free end side becomes longer and the wire on the fixed end side becomes shorter under the movement of the moving member 52.

[0037] It is obvious that as long as the spring 51 is not in a natural state, no matter it is currently in a stretched state or a compressed state, it will generate a force on the moving part 52, and this force will involve the movement of the wire at the free end, thereby changing the position of the output head 6, that is, causing the output head 6 to be unable to be fixed at the desired position. Obviously, such a situation is not allowed to occur. In order to solve this problem, when designing, the lower end face of the output head 6 is in friction contact with the inner wall of the bottom plate 1, and the friction force generated by the friction is greater than the rebound force of the spring 51, that is, the minimum friction force will also be greater than the maximum rebound force of the spring 51, so that the output head 6 can be ensured to be positioned in the chute 31. In this application, the output head 6 is made of soft rubber material as a whole, thereby increasing the friction force. Of course, only the lower end can be made of soft rubber material and the upper end can be formed of relatively hard materials such as plastic, so as to facilitate pulling in the chute, or other materials that can achieve the above effect can be used.

[0038] It should be mentioned that no matter how the wire on the free end side is extended or how the wire on the fixed end side is shortened, it will be limited by the length of the wire and even the fixed end of the wire. In other words, when the length of the wire 4 on the fixed end side is shortened to zero, the movable member 52 abuts against the fixed end of the wire 4. Specifically, in this embodiment, the wire 4 has two wires, namely the positive wire 41 and the negative wire 42. The fixed end of the positive wire 41 and the fixed end of the negative wire 42 are fixed to the bottom plate 1 through the fixed block 7. In this way, when the length of the wire on the fixed end side is shortened to 0, the movable member 52 abuts against the fixed block 7.

[0039] Based on the above limitation, the maximum moving distance of the wire on the free end side is twice the shortened distance of the wire on the fixed end side. Figure 1 As shown, the movement of the output head 6 is limited by the length of the slide groove 31. Therefore, in fact, the moving distance of the wire on the free end side is N times the shortened distance of the wire on the fixed end side, and the value of N is 0<N≤2. In order to give full play to the moving distance of the output head 6 and realize the adjustable length of the wire, the length of the slide groove 31 is equivalent to the moving distance of the output head 6 in the present application, that is, the length of the slide groove 31 is equal to N times the maximum distance between the moving part and the fixed end of the wire, and the value of N is 0<N≤2.

[0040] As for whether the spring is always in a compressed state or an extended state, or there is a change process from extension to natural state and then to a compressed state / from a compressed state to a natural state and then to a stretched state during the movement, the functions of the present application can be well realized, and only the connection position of the spring 51 and the moving member 52 needs to be adjusted. According to actual needs, the present application is preferably that when the output head 6 is located at the end of the slide slot 31 close to the one end of the spring 51, the spring 51 is in a stretched state, so that the spring is in a stretched state throughout the whole process, and this position of the output head 6 means that the stretched state of the spring 51 is the weakest, and when the output head 6 is located at the farthest end of the slide slot 31, the stretched state of the spring 51 is the largest, and at this time, it also corresponds to the wire 4 being in the longest elongated state.

[0041] In order to achieve good sliding of the wire 4 on the moving member 52, see Figure 2 The surface of the moving part 52 has two arc grooves 521 arranged in concentric circles. The free end of the positive wire 41 and the free end of the negative wire 42 pass through the corresponding arc grooves 521 and are connected to the output head 6. As an improvement, the inner wall of the arc groove 521 is set as a smooth curved surface to reduce the sliding friction of the wire and improve the sliding flexibility of the wire.

[0042] Continue to see Figure 1 and Figure 3The power rail also includes an input end cover 8 located at the end of the cavity 10 and extending into the cavity 10. The input end cover 8 is provided with a DC head 9. The DC head 9 divides a positive input line 91 and a negative input line 92. When the positive input line 91 and the negative input line 92 extend to the fixed block 7, they are divided into two paths. One path forms the aforementioned positive wire 41 and negative wire 42, and the other path continues to extend along the length direction of the cavity 10 after passing through the fixed block 7 to form the next positive input line and negative input line. It can be imagined that the panel 3 is along the The cavity 10 is also provided with a corresponding chute 31 corresponding to the next positive input line and the negative input line in the length direction. That is to say, the power rail can be provided with a plurality of chute, output head, moving part, spring, etc. as described above as needed to meet the lighting requirements of the shelf. This corresponds to the following structure on the panel 3, that is, the panel 3 is provided with a plurality of chute 31 distributed in series along the length direction of the cavity 10 for the subsequent output head 6 to pass through. Of course, at this time, the subsequent spring 51 is fixed on the fixed block 7, as shown in FIG. Figure 2 shown.

[0043] At the same time, since the positive input line 91 and the negative input line 92 are divided into two paths at the fixed block 7, and the fixed ends of the positive wire 41 and the negative wire 42 are both fixed in the fixed block 7, combined with Figures 2-3, it can be easily imagined that the fixed block 7 is equivalent to the fork of the line, and since the fixed block 7 covers the forked end of the line, it can prevent water vapor from entering, thereby playing a good waterproof role. The design of the fixed block 7 can make the waterproof performance of the power rail reach above IP65.

[0044] In order to facilitate sliding, the bottom plate 1 is provided with a slide rail 11 arranged along the length direction of the cavity 10, and the lower end surface of the moving member 52 and the lower end surface of the output head 6 are respectively formed with a slide groove 522 and a slide groove 61 suitable for sliding on the slide rail 11. At the same time, the bottom plate 1 is also provided with a steel wire 12 arranged along the length direction of the cavity 10, and the input end cover 8 and the fixing block 7 are respectively fixedly connected to the steel wire 12.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
