The embodiment provides a protection door which is particularly applied to a power rail of a rail socket, wherein the rail socket is a novel socket product and mainly comprises the power rail and an adapter in structure. The power supply rail is arranged on a wall or embedded into a desktop, the adapter is inserted into the power supply rail in a pluggable mode and can be inserted into any position of the power supply rail, the adapter is provided with a jack for taking electricity, and the plug of the electricity utilization device can be inserted into the jack of the adapter to take electricity.

The number of the adapters of the track socket can be flexibly increased and decreased according to the requirements, the positions can be flexibly adjusted according to the positions of the power utilization devices, the power lines of the power utilization devices are short, and the track socket is safer and more attractive than a common socket, so that the track socket is popular in the market due to the advantages.

The power supply rail mainly comprises a shell 1, a conducting plate, an insulating support and a junction box in structure, wherein the shell 1 serves as a shell of the power supply rail and plays a role in protection, and the material of the shell can be aluminum profiles. Regarding structural features of the case 1, as shown in fig. 1, the panel 111 of the case 1 has a rail hole 113, and the case 1 has an electrode channel 121 therein.

Thus, the conductive plate and the insulating holder are both installed in the electrode channel 121, and the conductive plate is held by the insulating holder, and a junction box having terminals for connecting the conductive plate with a power line in a wall is installed at one end of the housing 1. The power take-off portion of the adapter passes through the rail opening 113, extends into the electrode channel 121, and is in contact with the conductive plate in the electrode channel 121 to be electrically connected. The top of the adapter is provided with a jack for taking electricity, and a plug of an electricity utilization device is inserted into the jack of the adapter to take electricity.

Since the rail opening 113 of the power rail is opened to the outside, it is unsafe, water and dust are easily introduced, a safety accident occurs in the water introduction, and the introduced dust wears the conductive plate in the electrode channel 121, and the service life of the power rail is reduced in both water introduction and dust introduction.

Accordingly, the power supply rail may further include a protection door in the housing for shielding the rail hole 113 for dust prevention, foreign matter blocking, and aesthetic appearance.

In order to facilitate the insertion of the adaptor into the track opening 113, the protection door on the market is usually a soft rubber sealing strip which is easy to deform under extrusion, and after long-term use, the protection door is subjected to plastic deformation, collapses and can not be folded to achieve the sealing effect, and especially, the protection door is applied to kitchen environments with lampblack and salt, and the situation is more easy to happen. Moreover, the above-mentioned protection door is ageing hardening with higher speed in oil smoke and salt environment, also can influence the plug-in, the extracting of adapter and follow rail mouth and remove.

The power supply rail according to the embodiment has the advantages that the protection door is combined with the good elasticity of metal and the characteristics of good contact property, difficult aging and difficult deformation of plastic, the service life of the power supply rail can be prolonged, and the use experience of a user is enhanced.

The power supply rail includes a housing 1, and as to structural features of the housing 1, as shown in fig. 1 and 2, the housing 1 may include a housing cover 11 and a bottom plate 12, the housing cover 11 having a cover-like structure including a panel 111 and two side walls 112, the panel 111 having a rail opening 113 arranged along a length direction, wherein a center line of the rail opening 113 and a center line of the panel 111 may coincide, that is, the rail opening 113 is located at a center line position of the panel 111.

As shown in fig. 2 and referring to fig. 1, the bottom plate 12 may have a plate shape, and an upper surface of the bottom plate 12, that is, a surface facing the case cover 11, has an electrode channel 121.

Wherein the electrode channel 121 is positioned opposite the track opening 113 so that the power take-off portion of the adapter can be inserted into the track opening 113 and into the electrode channel 121 to electrically connect with the conductive plate in the electrode channel 121. In order to allow the adaptor to enter the electrode channel 121, as shown in fig. 1 and 2, the top wall of the electrode channel 121 facing the panel 111 has a relief opening 122, and the location of the relief opening 122 is opposite to the location of the rail opening 113.

With respect to the assembly of the cover 11 and the bottom plate 12, the cover 11 and the bottom plate 12 may be fixed together by screws, for example, the cover 11 and the bottom plate 12 are pre-positioned and then fixed using screws. The pre-positioning of the cover 11 and the base plate 12 can be achieved by means of a snap-fit.

For example, as shown in fig. 1 and 2, the upper surface of the base plate 12 may have second ribs 124 at both left and right sides of the electrode channel 121, the lower surface of the panel 111, that is, the surface facing the base plate 12, has third ribs 114 and fourth ribs 115, a first clamping groove 116 is formed between the third ribs 114 and the fourth ribs 115, and the second ribs 124 of the upper surface of the base plate 12 may be clamped in the first clamping groove 116 to achieve the predetermined positioning of the cover 11 and the base plate 12.

It should be noted that the second bead 124, the third bead 114, and the fourth bead 115 are each a strip-shaped bead arranged along the length direction of the housing 1.

In one example, since the power supply rail further includes a protection door installed in the case 1, the case 1 further has a protection door installation chamber therein, in which the protection door is installed, as shown in fig. 2, the protection door installation chamber is defined between the panel 111, the left and right third beads 114, the bottom plate 12, and the electrode channel 121.

The housing 1 is assembled by the cover 11 and the bottom plate 12, and in another example, the housing 1 may be an integrally formed structure including the cover 11 and the bottom plate 12.

The above description is about the structural features of the housing 1, and the specific structural features of the housing 1 are not specifically limited in this embodiment.

The power rail further comprises two protection doors 2, wherein the number of the protection doors 2 can be two, the two protection doors can be symmetrical with respect to a vertical plane where a central line of the rail mouth 113 is located, one protection door is located on the left side of the vertical plane and can be marked as a left protection door, and the other protection door is located on the right side of the vertical plane and can be marked as a right protection door.

When the protection door 2 is in an open state, the left protection door and the right protection door are separated, so that the rail mouth 113 is exposed, the adapter can extend into the electrode channel 121, and when the protection door 2 is in a closed state, the left protection door and the right protection door are in contact or close to be in contact, and jointly shield the rail mouth 113.

It can be seen that this power rail includes the protection door, and when the adapter did not insert in the rail road junction, the lamella of protection door sheltered from the rail road junction, plays sealed rail road junction's effect. When the adapter is inserted into the rail mouth, the adapter applies an acting force to the door sheet, the door sheet is pushed to one side of the rail mouth, the door sheet does not shield the rail mouth any more, the adapter is in contact with the conductive plate in the electrode channel, and when the adapter is pulled out of the rail mouth, the door frame rebounds to push the door sheet to a position where the rail mouth is shielded. Furthermore, the power supply rail can improve the safety of the power supply rail through shielding the rail mouth by the protection door, and achieve the effects of preventing water and dust from being discharged so as to prolong the service life of the power supply rail.

The structural features of the protective door 2 will be described below, and as shown in fig. 3 to 5, the protective door 2 includes a door frame 21 and a door leaf 22. The door 22 is used for shielding the rail hole 113, the door frame 21 is used as a fixing piece for installing the door 22 in the shell 1 and is also used as an elastic piece for resetting the door 22 to the rail hole 113.

As shown in fig. 3, the protection door 2 is positioned in the housing 1, and when the adapter is inserted into the rail mouth 113, the door 22 moves to the side of the rail mouth 113, and when the adapter is pulled out from the rail mouth 113, the door 22 moves to the shielding rail mouth 113 by the elastic action of the door frame 21. Wherein fig. 3 is a schematic view of the protection door 2 in an opened state.

In one example, the door 21 is made of metal, and the door 22 is made of plastic. The gantry 21 provides elasticity by virtue of the ductility of the metallic material. The door leaf 22 is made of plastic material, and compared with rubber material, the plastic material is harder, is not easy to deform and age, and is weak in influence of oil smoke and salt. Furthermore, the protection door can prolong the service life of the power supply rail and enhance the use experience of a user.

In order to enable the gantry 21 to provide elasticity, accordingly, as shown in fig. 4, the gantry 21 includes a spring piece 211, and the spring piece 211 may be a thin strip-like structure with a relatively thin thickness. A part of the spring piece 211 is connected to the door piece 22, and a part of the spring piece 211 is fitted in the housing 1.

In order for the elastic sheet 211 to provide good elasticity, accordingly, the elastic sheet 211 may include at least one elastic element or a plurality of elastic elements in the shape of U, V, S, W, wave, and spiral.

That is, the shape of the elastic piece 211 may be one shape or a combination of shapes of a U shape, a V shape, an S shape, a W shape, a wave shape, a spiral shape, and the like.

For the case where the elastic sheet 211 includes a plurality of elastic elements, that is, for the combination of the shapes of the elastic sheet 211, for example, the elastic sheet 211 includes an elastic element having a U shape, an elastic element having an S shape, and an elastic element having a W shape, that is, a part of the elastic sheet 211 has a U shape, a part has an S shape, and another part has a W shape.

In this embodiment, the specific shape of the elastic piece 211 is not limited, and elasticity can be provided to promote the restoration of the door 22.

In order to enable the elasticity of the elastic piece 211 to urge the door piece 22 to slide in a direction perpendicular to the rail opening 113, the elastic direction of the elastic piece 211, for example, the contraction direction or the extension direction of the elastic piece 211 is parallel to the moving direction of the door piece 22.

Accordingly, as shown in fig. 3, the opening of the U-shaped or V-shaped spring piece 211 faces the panel 111 or the bottom plate 12, and since the door piece 22 is next to the panel 111, the opening of the U-shaped or V-shaped spring piece 211 faces the panel 111. The spring piece 211 having a shape including a wave shape or a spiral shape or an S shape or a W shape is stretched in a direction corresponding to the moving direction of the door piece 22.

In order to reduce the space occupied by the elastic piece 211 in the housing 1, the elastic piece 211 may have a U-shape or V-shape as shown in fig. 4 and 5, respectively.

One side wall of the U-shaped or V-shaped spring piece 211 is fixedly connected with the door piece 22, and the other side wall is assembled in the housing 1.

In one example, the elastic piece 211 may be directly fixedly connected to the door piece 22, or may be indirectly connected to the door piece 22.

For example, the door frame 21 may further include a connection piece 212, the elastic piece 211 and the connection piece 212 are integrally formed, and the door piece 22 is fixed on the connection piece 212.

As an example, door tab 22 may be coated on the outer surface of connecting tab 212 by an injection molding process. As shown in fig. 6, the connecting piece 212 is in a quadrilateral sheet shape, and the door 22 is wrapped on the upper surface, the lower surface and the side surfaces of the connecting piece 212.

The door 22 may completely cover the connection piece 212, or may partially cover the connection piece 212.

In one example, to enhance the strength of the connection between the door leaf 22 and the connection piece 212, the connection piece 212 may have a through hole 2121 penetrating through the thickness direction, as shown in fig. 4.

Thus, after the injection molding liquid is poured into the die where the connecting sheet 212 is located, the injection molding liquid is filled in the upper part, the lower part and the holes of the connecting sheet 212, after the injection molding liquid is solidified, the injection molding liquid in the holes is solidified to form a columnar structure, and the solidified injection molding liquid above and below the connecting sheet 212 is connected together to play a role of reinforcing ribs.

As described above, a portion of the elastic piece 211 is connected to the door piece 22, and a portion of the elastic piece 211 is assembled in the housing 1, wherein the implementation of the assembly of the elastic piece 211 in the housing 1 can be as follows.

In which the spring piece 211 is exemplified in a U-shape or a V-shape.

One way may be that the spring piece 211 may be directly fitted in the housing 1. For example, the lower surface of the panel 111 may have a groove, and the side wall of the elastic piece 211 may be caught in the groove to realize the fitting of the elastic piece 211 in the housing 1.

In another example, the elastic piece 211 may also be indirectly assembled in the housing 1. For example, as shown in fig. 4 and 5, the gantry 21 may further include a fixing piece 213, where the fixing piece 213 is fixedly connected to the elastic piece 211, and the fixing piece 213 is configured to be assembled in the housing 1.

For example, the fixing piece 213 may have a U-shape or V-shape, the opening of the fixing piece 213 faces the bottom plate 12, one side wall of the fixing piece 213 is connected to the elastic piece 211, and the other side wall is assembled in the housing 1, for example, may be clamped on the inner surface of the housing 1.

As an example, as shown in fig. 7, the inner surface of the bottom plate 12, that is, the upper surface of the bottom plate 12 has first ribs 123 along its length direction, and the first ribs 123 may be caught between both sidewalls of the fixing piece 213.

As described above, the upper surface of the base plate 12 has the second ribs 124, and then, as shown in fig. 7, the second clamping groove 125 is formed between the first ribs 123 and the second ribs 124 on the upper surface of the base plate 12, and the side wall of the fixing piece 213 may be located in the second clamping groove 125, specifically, between the first ribs 123 and the third ribs 114.

Thus, as shown in fig. 7, the first rib 123 is located between two sidewalls of the fixing piece 213, and one sidewall of the fixing piece 213 is located in the second clamping groove 125 between the first rib 123 and the second rib 124, so that the door frame 21 can be assembled in the housing 1 through the fixing piece 213.

For example, in the assembly, as shown in fig. 7, the protection door 2 may be first assembled on the lower surface of the cover 11, for example, the panel 111 of the cover 11 may be placed on a tooling table, and the protection door 2 may be assembled in the cover 11. The base plate 12 is then preassembled on the housing cover 11, for example, with the second ribs 124 of the base plate 12 snapped into the first snap grooves 116, wherein the first ribs 123 are located between the two side walls of the U-shaped or V-shaped securing tabs 213. After that, the cover 11 and the bottom plate 12 are fixed together using screws.

Of course, it is also possible to assemble the protective door 2 on the upper surface of the bottom plate 12 first, then preassemble the cover 11 on the bottom plate 12, and then fix the cover 11 and the bottom plate 12 together using screws. The order of assembling the power supply rails is not particularly limited in this embodiment.

In which, for convenience of assembly, as shown in fig. 7, the position of the first bead 123 near the end is inclined toward the position of the electrode channel 121 to form a guide structure, so that the first bead 123 can be conveniently positioned between both sidewalls of the fixing piece 213, improving assembly efficiency.

The above is related to the structural features of the door frame 21 and the door leaf 22. As shown in fig. 6, the door leaf 22 may include a horizontal portion 221 and an inclined portion 222, where the horizontal portion 211 is wrapped on the outer surface of the connecting piece 212, and the inclined portion 222 is integrally formed with the horizontal surface 221.

Wherein, the included angle θ between the horizontal portion 211 and the inclined portion 222 may be an obtuse angle.

In one example, the angled portion 222 of the door 22 is guided when the adapter is inserted into the electrode channel 121 through the rail opening 113 so that the end of the angled portion 222 extends into the relief opening 122 of the electrode channel 121.

In one example, since the rail mouth 113 is disposed along the length direction of the power rail, that is, the rail mouth 113 is long-strip-shaped, the protection door 2 is also required to be long-strip-shaped. Correspondingly, the door frame 21 may be in a strip shape, the number of the elastic pieces 211 is multiple, the multiple elastic pieces 211 are sequentially arranged along the length direction of the door frame 21, the number of the door pieces 22 is multiple, the multiple door pieces 22 are sequentially arranged along the length direction of the door frame 21, and each door piece 22 is fixedly connected with at least one elastic piece 211.

As mentioned above, the door frame 21 further includes the connection piece 212, and then each door piece 22 is fixedly connected to at least one elastic piece 211 through one connection piece 212, that is, each door piece 22 is fixedly connected to one connection piece 212, and each connection piece 212 is fixedly connected to at least one elastic piece 211.

For example, one connection piece 212 is connected to one elastic piece 211, and then the elastic piece 211 may be connected to a middle position of the connection piece 212. For another example, as shown in fig. 4, one connecting piece 212 is connected to two elastic pieces 211, and then one elastic piece 211 is connected to one end of the connecting piece 212 in the length direction, and the other elastic piece 211 is connected to the other end of the connecting piece 212 in the length direction, wherein the length direction of the connecting piece 212 is a direction parallel to the length direction of the power supply rail.

Thus, when one adapter is inserted into the track hole 113, the n door leaves 22 are moved to the side of the track hole 113 by the acting force of the adapter, and the door leaves 22 which are not acted by the acting force of the adapter still keep shielding the track hole 113, and when the adapter is pulled out from the track hole 113, the n door leaves 22 are reset to shielding the track hole 113 under the elastic action of the connected elastic sheet 211.

Where n is a positive integer, for example, n may be 1, or may take a value from 2 to 8, and of course n may also be a value greater than 8.

It should be noted that, although the number of the elastic pieces 211 and the connecting pieces 212 of the gantry 21 is plural, the number of the fixing pieces 213 may be one, that is, the plurality of elastic pieces 211 may be all connected to the same fixing piece 213, and as shown in fig. 4, the fixing piece 213 may be elongated.

The door frame 21 may be an integrally formed structure, that is, the plurality of elastic pieces 211, the plurality of connecting pieces 212, and the one fixing piece 213 are integrally formed.

In one example, the length of one portal 21 may be adapted to the length of the rail opening 113, e.g., the length of the portal 21 may be approximately equal to the length of the rail opening 113.

In another example, since the track opening 113 is relatively long, the number of the door frames 21 may be plural, and the door frames 21 are sequentially abutted end to end along the length direction of the track opening 113.

For example, a plurality of the gantries 21 are arranged on the left side of the rail mouth 113, the plurality of gantries 21 are arranged in a head-to-tail joint in sequence along the length direction of the rail mouth 113, a plurality of the gantries 21 are arranged on the right side of the rail mouth 113, and the plurality of gantries 21 are arranged in a head-to-tail joint in sequence along the length direction of the rail mouth 113.

In one example, the protective door 2 may be referred to as an integrated protective door because the door piece 22 is coated on the outer surface of the connection piece 212 of the door frame 21 through an injection molding process.

The present embodiment further provides a track socket, as shown in fig. 8 and fig. 9, which includes a power track 100 and adapters 200, where the power track 100 is the power track described above, and the number of adapters 200 is plural, and each adapter 200 is connected to the power track 100 in a pluggable manner.

As shown in fig. 8, when the adapter 200 is not inserted into the rail opening 113, the protection door of the power rail 100 is in a closed state, and when the adapter 200 is inserted into the rail opening 113, the protection door is in an open state so that the power-taking portion of the adapter protrudes into the electrode channel 121.

In this embodiment, the power supply rail of the rail socket includes a protection door, and when the adapter is not inserted into the rail mouth, the door sheet of the protection door shields the rail mouth, and plays a role in sealing the rail mouth. When the adapter is inserted into the rail mouth, the adapter applies an acting force to the door sheet, the door sheet is pushed to one side of the rail mouth, the door sheet does not shield the rail mouth any more, the adapter is in contact with the conductive plate in the electrode channel, and when the adapter is pulled out of the rail mouth, the door frame rebounds to push the door sheet to a position where the rail mouth is shielded. Furthermore, the power supply rail can improve the safety of the power supply rail through shielding the rail mouth by the protection door, and achieve the effects of preventing water and dust from being discharged so as to prolong the service life of the power supply rail.

The foregoing description of the preferred embodiments of the present disclosure is provided for the purpose of illustration only, and is not intended to limit the disclosure to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, alternatives, and alternatives falling within the spirit and scope of the disclosure.
