Abstract
Description
Technical Field
[0001] This invention relates to the field of low-voltage electrical appliances, specifically to a dustproof door assembly, a power rail, and a rail socket. Background Technology
[0002] As living standards improve, people need to use more and more electrical appliances, leading to a greater demand for wall sockets. Ordinary wall sockets are often insufficient, while installing too many can be aesthetically displeasing. Therefore, track sockets have emerged. A track socket consists of an adapter and a long, narrow track. The track is installed on the wall, and the track sockets are electrically connected to the wall's power supply line. The adapter has conductive tabs and sockets. When using a track socket, the conductive tabs of the adapter are inserted into the track slots, making contact with the track sockets. The appliance's plug is then inserted into the adapter's socket, allowing the appliance to draw power from the adapter. The advantage of track sockets is that the adapter can slide freely within a certain range along the track, enabling it to power appliances in multiple locations.
[0003] However, the power rail housing has a rail opening for the adapter to be inserted, and dust can easily enter the interior of the power rail through the rail opening, causing wear on the internal conductive plates and reducing the service life of the power rail. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dustproof door assembly, a power rail, and a rail socket.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A dustproof door assembly includes: a plurality of dustproof doors, a dustproof door bracket, and an elastic element;
[0007] The dustproof door bracket is at least located on one side of the track insertion port. The plurality of dustproof doors are slidably mounted on the dustproof door bracket via the elastic element, and the plurality of dustproof doors are arranged along the track insertion port. The track insertion port is closed under the drive of the elastic element.
[0008] Each dustproof door has a driving ramp at the drive end corresponding to the track insertion port. Each dustproof door has a first linkage structure and a second linkage structure on both sides. A dustproof door can be linked with the second linkage structure of an adjacent dustproof door through the first linkage structure. Furthermore, the first linkage structure and the second linkage structure between two adjacent dustproof doors are provided with a linkage gap so that the sliding distance of the linked dustproof door is less than the sliding distance of the dustproof door driven by the adapter.
[0009] Preferably, the first linkage structure is a linkage rod disposed on one side of the dustproof door, and the second linkage structure is a first linkage surface and a second linkage surface disposed on the other side. The linkage rod on one dustproof door is disposed within the sliding stroke range of the first linkage surface of the other adjacent dustproof door, and the second linkage surface is disposed within the sliding stroke range of the linkage rod. The linkage gap includes the first linkage gap between the linkage rod and the first linkage surface and the second linkage gap between the linkage rod and the second linkage surface.
[0010] Preferably, a linkage groove is provided on the side of the dustproof door opposite to the linkage rod, and the first linkage surface and the second linkage surface are provided on the side wall of the linkage groove. The linkage rod of the dustproof door extends between the first linkage surface and the second linkage surface of the adjacent dustproof door.
[0011] Preferably, the dustproof door bracket is provided with multiple bracket units, and each dustproof door is individually installed in a bracket unit for sliding.
[0012] Preferably, the bracket unit is provided with a sliding surface and a limiting boss for the dustproof door to slide, and the bottom of the dustproof door is provided with a sliding part corresponding to the limiting boss and the sliding surface.
[0013] Preferably, the sliding part is provided with a first limiting surface at the end corresponding to the dustproof door drive end, which mutually limits the end of the limiting boss to restrict the retraction stroke of the dustproof door;
[0014] And / or, the bottom surface of the sliding part is provided with a protruding second limiting part, the sliding surface is provided with a second limiting groove, the second limiting part slides in the second limiting groove, and its forward stroke is limited by the end of the second limiting groove near the dust door.
[0015] Preferably, the elastic element is a columnar spring, the tail end of the dustproof door is provided with a limiting protrusion, the bracket unit is provided with a limiting hole, one end of the columnar spring is sleeved on the limiting protrusion, and the other end is embedded in the limiting hole.
[0016] Preferably, dustproof door brackets are provided on both sides of the track insertion port, and multiple dustproof doors are symmetrically arranged on the dustproof door brackets on both sides, with the dustproof doors on both sides jointly sealing the track insertion port.
[0017] The present invention also provides a power rail, comprising: a rail body and a rail frame, wherein the rail frame is provided with a cavity, the rail body is disposed in the cavity, and any of the above-mentioned dustproof door components are further provided on the rail body.
[0018] The present invention also provides a track socket, an adapter, and the aforementioned power track with a dustproof door assembly, wherein the adapter is pluggably connected to the power track.
[0019] This invention relates to a dustproof door assembly for a track socket. Each dustproof door has a first linkage structure and a second linkage structure on both sides. A dustproof door can be linked with the second linkage structure of an adjacent dustproof door through the first linkage structure. A linkage gap is provided between the first and second linkage structures of two adjacent dustproof doors to ensure that the sliding distance of the linked dustproof door is less than the sliding distance of the dustproof door driven by the adapter. When the dustproof door driven by the adapter moves an adjacent dustproof door, the sliding distance of the adjacent linked dustproof door in the retracting direction is less than the sliding distance of the dustproof door driven by the adapter. This avoids all dustproof doors being fully opened when the adapter is inserted, or generating significant resistance that prevents the adapter from being inserted. With a suitable linkage gap, the number of adjacent linked dustproof doors can be controlled to a small range, allowing the adapter itself to shield the track insertion area of the opened dustproof door. Furthermore, the appropriately sliding dustproof door with a small opening allows the adapter to slide along the track insertion opening. Attached Figure Description

[0038] The specific embodiments of the dustproof door assembly of the present invention are further described below with reference to the accompanying drawings. The dustproof door assembly of the present invention is not limited to the descriptions in the following embodiments.
[0039] like Figure 1 The diagram shows a track socket provided in this embodiment. The track socket includes a power track and an adapter 9, which is pluggably connected to the power track.
[0040] like Figure 2 and Figure 3 As shown, the power rail in this embodiment includes a rail frame 4, a rail body 7, and a dustproof door assembly. The rail frame 4 is provided with a cavity 41, and the rail body 7 and the dustproof door assembly are disposed in the cavity 41. The rail body 7 generally includes an insulating bracket and an electrode conductive sheet disposed in the insulating bracket to achieve conductive connection with the adapter 9 and insulation with the rail frame 4 (usually the rail frame is a metal profile, but the rail frame can also be an insulating material).
[0041] In this embodiment, the adapter 9 can be arranged on the power rail by increasing or decreasing the number of adapters, and can slide on the power rail in the area with conductive electrode sheets.
[0042] like Figure 2As shown, the track body 7 includes two parts arranged opposite each other within the cavity 41, forming a track insertion port 71. An opening is also provided at the corresponding position of the track outer frame 4 to facilitate the insertion of the adapter 9. The dustproof door assembly in this embodiment is mainly used to protect the track insertion port 71. When no adapter is inserted, the track insertion port 71 remains closed. When an adapter is inserted, only the dustproof door at the corresponding position of the adapter is opened.
[0043] like Figure 4-10 The dustproof door assembly provided in this embodiment is shown. This assembly is located at the upper end of the track body 7 and includes: multiple dustproof doors 3, a dustproof door bracket 1, and an elastic element 2. The dustproof door bracket 1 is at least located on one side of the track insertion port 71. The multiple dustproof doors 3 are slidably mounted on the dustproof door bracket 1 via the elastic element 2 (i.e., multiple dustproof doors 3 are at least located on one side of the track insertion port 71), and the multiple dustproof doors 3 are arranged along the track insertion port, closing the track insertion port under the drive of the elastic element 2. Each dustproof door 3 has a driving slope 35 at the driving end corresponding to the track insertion port 71. When the adapter is inserted, it contacts the driving slope 35. Under continuous downward pressure acting on the driving slope 35, the dustproof door 3 compresses the elastic element 2, and the dustproof door 3 slides back to the side away from the track insertion port, opening space for the adapter to continue inserting.
[0044] In this embodiment, each dustproof door 3 is provided with a first linkage structure and a second linkage structure on both sides. A dustproof door 3 can be linked with the second linkage structure of an adjacent dustproof door 3 through the first linkage structure. Furthermore, a linkage gap is provided between the first and second linkage structures of two adjacent dustproof doors 3 so that the sliding distance of the linked dustproof door 3 is less than the sliding distance of the dustproof door 3 driven by the adapter. When the adapter is inserted into the track to draw power, when the dustproof door 3 driven by the adapter moves the adjacent dustproof door 3, the sliding distance of the adjacent linked dustproof door 3 in the retracting direction is less than the sliding distance of the dustproof door 3 driven by the adapter. This avoids all dustproof doors 3 from being fully opened when the adapter is inserted, or from generating significant resistance that prevents the adapter from being inserted. With a suitable linkage gap setting, the number of adjacent dustproof doors 3 that are linked can be controlled to a small number. Only the dustproof doors in the area covered by the adapter will be appropriately opened so that the adapter itself can shield the track insertion port 71 area of the opened dustproof door 3, blocking dust, oil stains and other objects, thereby protecting the cleanliness of the components inside the track insertion port.
[0045] It is worth noting that in this embodiment, the linkage between the first linkage structure and the second linkage structure can be either the first linkage structure driving the second linkage structure or the second linkage structure driving the first linkage structure.
[0046] In this embodiment, as Figure 7 , Figure 9 and Figure 10 As shown, the first linkage structure is a linkage rod 33 disposed on one side of the dustproof door 3, and the second linkage structure is a first linkage surface 361 and a second linkage surface 362 disposed on the other side. The linkage rod 33 on one dustproof door 3 is located within the sliding stroke range of the first linkage surface 361 of the other adjacent dustproof door 3, and the second linkage surface 362 is located within the sliding stroke range of the linkage rod 33. The linkage gap includes a first linkage gap h1 between the linkage rod 33 and the first linkage surface 361 and a second linkage gap h2 between the linkage rod 33 and the second linkage surface 362. The linkage rod 33 of the dustproof door 3 extends between the first linkage surface 361 and the second linkage surface 362 of the adjacent dustproof door 3; or the linkage rod 33 of the adjacent dustproof door 3 extends between the first linkage surface 361 and the second linkage surface 362 of the dustproof door 3.
[0047] like Figure 7 As shown, when the dustproof door 3 is the main body driven by the adapter, the first linkage surface 361 has a first linkage gap h1 between it and the linkage rod 33 of the adjacent dustproof door. When the dustproof door 3 driven by the adapter starts to slide, it must first move the distance of the first linkage gap h1 before it can drive the linkage rod 33 of the adjacent dustproof door, thereby driving the adjacent dustproof door to slide.
[0048] When the dustproof door 3 is the main body to be linked, the adjacent dustproof door is driven to slide by the adapter. The linkage rod 33 slides the distance of the second linkage gap h2 before it begins to contact the second linkage surface 362, thereby driving the current dustproof door 3 to slide.
[0049] In this embodiment, a linkage groove 36 is provided on the side of the dustproof door 3 opposite to the linkage rod 33, and the first linkage surface 361 and the second linkage surface 362 are provided on the side wall of the linkage groove 36. This can reduce the overall thickness of the dustproof door 3, and also reduce the size of the track frame.
[0050] In a preferred embodiment, the linkage rod 33 is positioned between the first linkage surface 361 and the second linkage surface 362, meaning the size of the first linkage gap h1 is equal to the size of the second linkage gap h2. This effectively controls the sliding distance of the linked dustproof door, allowing the linked dustproof doors to have the same sliding distance, so that the adapter can further drive the linked dustproof door to open when sliding.
[0051] In this embodiment, as Figure 2-8The dustproof door bracket 1 shown is mounted on the track body 7. Optionally, the dustproof door bracket 1 and the insulating bracket of the track body 7 are an integral structure. Of course, they can also be separate structures assembled through a connecting structure. The dustproof door bracket 1 is provided with multiple bracket units 10, and each dustproof door 3 is individually mounted in a bracket unit 10 for sliding.
[0052] Specifically, such as Figure 8 As shown, the support unit 10 is provided with a sliding surface 12 and a limiting boss 11 for the dustproof door 3 to slide. The two limiting bosses 11 are arranged in parallel to form a concave slide rail. The bottom of the dustproof door 3 is provided with a sliding part 34 corresponding to the limiting boss 11 and the sliding surface 12. The sliding part 34 is adapted to the shape of the concave slide rail. Of course, the shape of the slide rail is not limited to a concave structure; it can also be convex or other structures that can mutually limit each other.
[0053] Furthermore, the sliding part 34 is provided with a first limiting surface 341 at the end corresponding to the driving end of the dustproof door 3, which mutually limits the end of the limiting protrusion 11 to restrict the retraction stroke of the dustproof door 3. That is, when the adapter drives the dustproof door 3 to slide, the end of the limiting protrusion 11 limits the first limiting surface 341 to prevent the dustproof door 3 from sliding excessively.
[0054] Furthermore, the bottom surface of the sliding part 34 is provided with a protruding second limiting part 342, and the sliding surface 12 is provided with a second limiting groove 121. The second limiting part 342 slides in the second limiting groove 121, and its forward stroke is limited by the end of the second limiting groove 121 near the dust door 3.
[0055] In this embodiment, the elastic element 2 is a columnar spring, the tail end of the dustproof door 3 is provided with a limiting protrusion 31, the bracket unit 10 is provided with a limiting hole 15, one end of the columnar spring is sleeved on the limiting protrusion 31, and the other end is embedded in the limiting hole 15. Of course, the elastic element 2 can also be a torsion spring or other elastic elements.
[0056] In this embodiment, dustproof door brackets 1 are provided on both sides of the track insertion port 71, and multiple dustproof doors 3 are symmetrically arranged on the dustproof door brackets 1 on both sides, and the dustproof doors 3 on both sides together close the track insertion port 71.
[0057] Of course, when the width of the track insertion port 71 is small, a dustproof door 3 can be installed on only one side, meaning only a dustproof door bracket 1 needs to be installed on one side. This saves material costs and assembly and processing costs. (Reference) Figure 7 As shown, by simply setting a corresponding adapter limiting structure on the other side, and keeping the adapter driving the inclined surface of the dustproof door 3, the dustproof door 3 on one side can also close the track insertion port 71.
[0058] like Figure 11 As shown, this illustrates the state of each dust door when the adapter is inserted into one side of the dust door. When the adapter is inserted into the track insertion port and drives dust door 3-1, with the bottom of the adapter resting against the driving ramp of dust door 3-1, under the action of external force, dust door 3-1 moves a distance greater than the linkage gap, and then comes into contact with the adjacent dust door 3-2, causing the adjacent dust door 3-2 to slide backward, thus creating a space for the adapter to be inserted. Due to the action of the adapter, the dust door 3-1 in contact with it exits the maximum gap, and through the linkage rod 33 or the linkage groove 36, it drives the adjacent dust door to move in the same direction. When the dust door 3-1 is squeezed out of the maximum gap, it will cause the adjacent dust door 3-2 to move back appropriately, thus leaving space for the adapter to slide along both sides of the track. Since the displacement of the dust door 3-2 is not large enough to move the dust door 3-3, the dust door 3-3 will still be in its original design position and be stuck to the dust door in the other dust door assembly. The dust doors that have moved back are all located at the bottom of the adapter, and the adapter will play a temporary dust protection role.
[0059] It should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship conventionally placed during use.

[0060] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
