Description

Technical Field

[0001] The utility model relates to the field of low-voltage electrical appliances, and in particular to a dustproof door component, a power rail and a rail socket. Background Art

[0002] As the quality of life improves, people need to use more and more types of electrical appliances, so the demand for the number of wall sockets is also increasing. The number of ordinary wall sockets is often not enough, and if too many wall sockets are installed, it will affect the appearance. Therefore, track sockets came into being. The track socket includes an adapter and a long track. The track is installed on the wall, and the track socket in the track is electrically connected to the wall power supply line. The adapter has a conductive sheet and a socket. When using the track socket, the conductive sheet of the adapter is inserted into the track slot of the track and contacts the track socket in the track slot. Then the plug of the electrical appliance is inserted into the socket of the adapter, and the electrical appliance can draw power from the adapter. The advantage of the track socket is that the adapter can be moved arbitrarily within a range by sliding the adapter in the track, so that the adapter can power electrical appliances in multiple locations.

[0003] However, the housing of the power rail has a rail opening for inserting the adapter, and dust can easily enter the interior of the power rail through the rail opening, causing wear to the internal conductive plate, thereby reducing the service life of the power rail. Utility Model Content

[0038] The following embodiments are combined with the accompanying drawings to further illustrate the specific implementation of the dustproof door assembly of the present utility model. The dustproof door assembly of the present utility model is not limited to the description of the following embodiments.

[0039] like Figure 1 The figure shows a track socket provided by the present embodiment, which includes a power track and an adapter 9, and the adapter 9 is pluggably connected to the power track.

[0040] like Figure 2 and Figure 3 As shown, the power track of this embodiment includes a track outer frame 4, a track body 7 and a dustproof door assembly, the track outer frame 4 is provided with a cavity 41, the track body 7 and the dustproof door assembly are arranged in the cavity 41, wherein the track body 7 generally includes an insulating bracket and an electrode conductive sheet arranged in the insulating bracket, so as to achieve a conductive connection with the adapter 9 and achieve insulation with the track outer frame 4 (usually the track outer frame is a hardware profile, of course, the track outer frame can also be an insulating material).

[0041] In this embodiment, the adapters 9 can be arranged on the power rail by increasing or decreasing the number thereof, and can slide on the area of ​​the power rail having the electrode conductive sheet.

[0042] like Figure 2As shown, the track body 7 includes two tracks that are relatively arranged in the cavity 41 and form a track insertion opening 71. The corresponding position of the track outer frame 4 is also provided with an opening to facilitate the insertion of the adapter 9. The dustproof door assembly of this embodiment is mainly used to protect the track insertion opening 71. When no adapter is inserted, the track insertion opening 71 is always kept 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 the present embodiment is shown, and the dustproof door assembly is arranged at the upper end of the track body 7, and comprises: a plurality of dustproof doors 3, a dustproof door bracket 1 and an elastic member 2; the dustproof door bracket 1 is arranged at least on one side of the track insertion opening 71, and the corresponding plurality of dustproof doors 3 are slidably arranged on the dustproof door bracket 1 through the elastic member 2 (that is, the plurality of dustproof doors 3 are arranged at least on one side of the track insertion opening 71), and the plurality of dustproof doors 3 are arranged in an array along the track insertion opening, and the track insertion opening is closed under the drive of the elastic member 2; a driving slope 35 is arranged at the driving end of each dustproof door 3 corresponding to the track insertion opening 71, and when the adapter is inserted, it contacts the driving slope 35, and when the continuous downward pressure acts on the driving slope 35, the dustproof door 3 compresses the elastic member 2, and the dustproof door 3 slides back to the side away from the track insertion opening, opening a space for the adapter to continue to be inserted.

[0044] In this embodiment, a first linkage structure and a second linkage structure are respectively provided on both sides of each dustproof door 3, and a dustproof door 3 can be linked with the second linkage structure of an adjacent dustproof door 3 through the first linkage structure, and a linkage gap is provided between the first linkage structure and the second linkage structure of two adjacent dustproof doors 3 so that the sliding distance of the linked dustproof door 3 is smaller 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 drives the adjacent dustproof door 3, the distance that the adjacent linked dustproof door 3 slides in the retreat direction is smaller than the distance that the dustproof door 3 driven by the adapter slides. This can prevent all dustproof doors 3 from being fully opened when the adapter is inserted, or from generating huge resistance to prevent the insertion of the adapter. With the appropriate setting of the linkage gap, the number of adjacent dustproof doors 3 to be linked can be controlled within a small range, and only the dustproof doors in the area covered by the adapter will be appropriately retreated, so that the adapter itself can be used to shield the track insertion port 71 area of ​​the opened dustproof door 3 to block the entry of dust, oil stains and other objects, thereby protecting the cleanliness of the components inside the track plug.

[0045] It should be noted that, in this embodiment, the linkage between the first linkage structure and the second linkage structure may be that the first linkage structure drives the second linkage structure, or the second linkage structure drives the first linkage structure.

[0046] In this embodiment, if Figure 7 , Fig. 9 and Fig.10 As shown, the first linkage structure is a linkage rod 33 arranged 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 arranged on the other side, wherein the linkage rod 33 on one dustproof door 3 is arranged within the sliding stroke range of the first linkage surface 361 of another adjacent dustproof door 3, and the second linkage surface 362 is arranged within the sliding stroke range of the linkage rod 33, and 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 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 dust door 3 is driven by the adapter, the first linkage surface 361 has a first linkage gap h1 with the linkage rod 33 of the adjacent dust door. When the dust 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 dust door, thereby driving the adjacent dust door to slide.

[0048] When the dustproof door 3 is used as the main body to be linked, the adjacent dustproof door is driven to slide by the adapter, and the linkage rod 33 starts to contact the second linkage surface 362 after sliding the distance of the second linkage gap h2, 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. In this way, the thickness of the entire dustproof door 3 can be reduced, and the volume of the track outer frame can also be reduced.

[0050] As a preferred embodiment, the linkage rod 33 is arranged between the first linkage surface 361 and the second linkage surface 362, that is, the size of the first linkage gap h1 is equal to the size of the second linkage gap h2. In this way, the sliding distance of the linked dustproof door can be effectively controlled, for example, the linked dustproof door can have the same sliding distance, so that the adapter can further drive the linked dustproof door to open when sliding.

[0051] In this embodiment, if Figure 2-8The dustproof door bracket 1 is arranged on the track body 7. Optionally, the dustproof door bracket 1 and the insulating bracket of the track body 7 are an integrated structure. Of course, they can also be a split structure and assembled through a connecting structure. The dustproof door bracket 1 is provided with a plurality of bracket units 10, and each dustproof door 3 is separately arranged in a bracket unit 10 for sliding.

[0052] Specifically, Figure 8 As shown, the bracket unit 10 is provided with a sliding surface 12 and a limiting boss 11 for sliding the dustproof door 3, and the two limiting bosses 11 are arranged in parallel to form a concave slide rail, and the bottom of the dustproof door 3 is provided with a sliding portion 34 corresponding to the limiting boss 11 and the sliding surface 12, and the sliding portion 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, and can also be a convex shape or other structures that can limit each other.

[0053] Furthermore, the end of the sliding portion 34 corresponding to the driving end of the dustproof door 3 is provided with a first limiting surface 341, which forms a mutual limit with the end of the limiting boss 11 to limit the retreat stroke of the dustproof door 3. That is, when the adapter drives the dustproof door 3 to slide, the end of the limiting boss 11 limits the first limiting surface 341 to prevent the dustproof door 3 from sliding excessively.

[0054] Furthermore, the bottom surface of the sliding portion 34 is also provided with a protruding second limiting portion 342, and the sliding surface 12 is provided with a second limiting groove 121. The second limiting portion 342 slides in the second limiting groove 121, and its forward stroke is limited by the end of the second limiting groove 121 close to the dustproof door 3.

[0055] In this embodiment, the elastic member 2 is a columnar spring, a limiting boss 31 is provided at the rear end of the dustproof door 3, the bracket unit 10 is provided with a limiting hole 15, one end of the columnar spring is sleeved on the limiting boss 31, and the other end is embedded in the limiting hole 15. Of course, the elastic member 2 can also be other elastic members such as a torsion spring.

[0056] In this embodiment, dustproof door brackets 1 are provided on both sides of the track insertion opening 71 , and a plurality of dustproof doors 3 are symmetrically provided on the dustproof door brackets 1 on both sides, and the dustproof doors 3 on both sides jointly close the track insertion opening 71 .

[0057] Of course, when the width of the rail insertion opening 71 is small, the dustproof door 3 can be set on one side, that is, the dustproof door bracket 1 only needs to be set on one side, which can save material costs and assembly and processing costs. Figure 7 As shown, it is only necessary to set a corresponding adapter limiting structure on the other side, and keep the adapter driving the driving inclined surface of the dustproof door 3, so that the single-sided dustproof door 3 can also achieve the closure of the track insertion opening 71.

[0058] like Fig.11 The figure shows the state of each dustproof door when the dustproof door on one side is inserted by the adapter. When the adapter is inserted into the track insertion port and drives the dustproof door 3-1, when the bottom of the adapter leans against the driving inclined plane of the dustproof door 3-1, under the action of external force, the dustproof door 3-1 moves a distance greater than the linkage gap, and then leans against the adjacent dustproof door 3-2, causing the adjacent dustproof door 3-2 to slide back, thereby splitting a space to allow the adapter to be inserted. Due to the action of the adapter, the dustproof door 3-1 in contact with it withdraws from the maximum gap, and drives the adjacent dustproof door to move in the same direction through the linkage rod 33 or the linkage groove 36. When the dustproof door 3-1 is squeezed out of the maximum gap, it will drive the adjacent dustproof door 3-2 to move backward appropriately, thereby leaving space for the adapter to slide along both sides in the track. Since the displacement of the dustproof door 3-2 is not large enough to drive the dustproof door 3-3 to move, the dustproof door 3-3 is still located in the original design position and is pressed against the dustproof door in another dustproof door assembly. The retreated dustproof doors are all located at the bottom of the adapter, and the adapter will play a temporary dustproof role.

In addition, the terms "first", "second", "third", etc. are only used to distinguish descriptions, and cannot be understood as indicating relative importance.

[0060] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
