Description

Technical Field

[0001] This utility model relates to electrical appliances, and in particular to a power supply track with a protective door. Background Technology

[0002] For the power rail of a track socket, the track body has an insertion opening. The power-taking arm of the adapter can be inserted into the track body through the insertion opening and come into contact with the conductive strip to draw power. Simultaneously, the adapter is also fixed to the track body through the insertion opening. To protect the internal structure when the adapter is not installed, a protective structure is usually configured to seal the insertion opening. One existing protective structure uses a protective door assembly, which includes a door seat, a protective door, and a resilient element. The protective door assembly is installed on the track body, the protective door is movably mounted on the door seat, and the resilient element is positioned between the door seat and the protective door, allowing the protective door to elastically extend and retract. When the adapter is not connected, the protective door can cover the insertion opening of the track body under the action of the resilient element. When the adapter is installed, the structure on the adapter can push open the protective door, thus not affecting the installation of the adapter. An existing protective door assembly, in order to limit the range of motion of the protective door and prevent it from detaching, has an insertion hole in the door seat, with a locking groove on the wall of the insertion hole. The protective door has a hook part, which inserts into the insertion hole of the door seat and hooks into the locking groove. The hook part is confined within the locking groove, thus ensuring that the protective door will not detach from the door seat and can move within a certain range of extension and contraction. For the symmetry of the connection, the hook part is set as two back-to-back latches, and corresponding locking grooves are also provided on the two opposite side walls of the insertion hole. The structure of the protective door, the door seat, and the protective door itself are all relatively complex, making manufacturing difficult. Utility Model Content

[0031] Reference Figures 1 to 6 A power rail with a protective door includes a rail body 100 and a protective door assembly 200. The rail body 100 has an insertion opening 110 extending along its length. The protective door assembly 200 is mounted on the rail body 100 and includes a door seat 210, a protective door 220, and an elastic member 230. The protective door 220 is movably disposed on the door seat 210 and has a covered position and a yielding position: in the covered position, the protective door 220 covers the insertion opening 110; in the yielding position, the protective door 220 moves away from the covered position. The elastic member 230 is disposed between the protective door 220 and the door seat 210 and is used to give the protective door 220 a tendency to enter the covered position. The track body 100 is provided with a limiting abutment part 120, and the protective door 220 is limited between the door seat 210 and the limiting abutment part 120. When the protective door 220 abuts against the limiting abutment part 120, the protective door 220 is in the covered position. When the part of the protective door 220 that cooperates with the limiting abutment part 120 moves away from the limiting abutment part 120, the protective door 220 enters the yielding position.

[0032] The aforementioned power rail body 100, together with the door seat 210, limits and protects the door 220, preventing the door 220 from detaching from the door seat 210. The rail body 100 limits the door 220 through the limiting abutment part 120, making full use of the rail body 100 as a limiter on one side. This avoids the need for complex limiting and matching structures on the door seat 210 and the door 220, facilitating manufacturing.

[0033] In this embodiment, the door seat 210 is provided with a sliding groove 211, and the protective door 220 is adapted to and slidably disposed on the sliding groove 211. The sliding groove 211 cooperates with the protective door 220 to realize the movement of the protective door 220. The structure is simple, easy to implement, and the operation is stable.

[0034] In this embodiment, guide grooves 310 and guide bars 320 are correspondingly provided between the two sidewalls of the sliding groove portion 211 and the corresponding sides of the protective door 220. The guide grooves 310 and guide bars 320 extend along the sliding direction of the protective door 220, and the guide bars 320 are adapted to and slide in cooperation with the guide grooves 310. Using the above structure, the cooperation between the guide grooves 310 and guide bars 320 forms a guide and further improves the stability of the sliding cooperation. In this embodiment, the guide grooves 310 and guide bars 320 are respectively provided on the door seat 210 and the protective door 220. In some embodiments, the positions of the guide grooves 310 and guide bars 320 can also be interchanged, i.e., the guide bars 320 are provided on the door seat 210, and the guide grooves 310 are provided on the protective door 220.

[0035] In this embodiment, the elastic element 230 is a spring, with its two ends abutting against the protective door 220 and the door seat 210, respectively. The door seat 210 is provided with a first positioning post 212, and the protective door 220 is provided with a second positioning post 221. The first positioning post 212 and the second positioning post 221 are opposite to each other, and the two ends of the elastic element 230 are respectively sleeved on the first positioning post 212 and the second positioning post 221. Using the above structure, the elastic element 230 can be stably positioned and installed. It is conceivable that in other embodiments, the elastic element 230 is not limited to a spring; for example, a spring sheet or other structures that can provide elasticity can also be used. When other elastic structures are used, the installation method can be configured according to the actual situation.

[0036] In this embodiment, the door seat 210 is provided with multiple protective doors 220. The door seat 210 includes a main crossbeam portion 213 and multiple longitudinal beam portions 214. The longitudinal beam portions 214 are perpendicular to the main crossbeam portion 213, and one end of each longitudinal beam portion 214 is connected to the main crossbeam portion 213. The longitudinal beam portions 214 are arranged at intervals along the length direction of the main crossbeam portion 213. Adjacent longitudinal beam portions 214 and the main crossbeam portion 213 enclose each other to form a sliding groove portion 211 corresponding to a protective door 220. With the above structure, the door seat 210 can form multiple sliding groove portions 211 through the main crossbeam portion 213 and each longitudinal beam portion 214, thereby adapting to install multiple protective doors 220.

[0037] In this embodiment, the track body 100 is provided with an installation channel 130 extending along the length of the track body 100. The door seat 210 is adapted to and installed in the installation channel 130, and the limiting abutment part 120 is the inner wall surface of the installation channel 130. With the above structure, the door seat 210 can be stably installed, and the limiting abutment part 120 is formed by the inner wall surface of the installation channel 130, resulting in a simple structure.

[0038] In this embodiment, the mounting channel 130 includes a main channel 131 and an extension channel 132. The main channel 131 communicates with the extension channel 132, and the extension channel 132 communicates with the insertion opening 110. The protective door 220 includes a door panel body 222 and a hooking part 223 disposed on the door panel body 222. The door panel body 222 is movably disposed on the extension channel 132, and the hooking part 223 is disposed on the main channel 131. The limiting abutment part 120 is the inner wall surface of the main channel 131. The limiting abutment part 120 is used to cooperate with the hooking part 223 and limit the protective door 220. The above structure is used to achieve the limiting cooperation between the limiting abutment part 120 and the protective door 220, and the structure is simple.

[0039] In one embodiment, the mounting channel 130 has an insertion opening at one end along its length. The door seat 210 and the protective door 220 are inserted into the mounting channel 130 through the insertion opening, thus facilitating assembly. In another embodiment, the track body 100 is provided with an end cap 140 to seal the insertion opening.

[0040] In this embodiment, the protective door 220 is provided with a hook portion 224, and the door seat 210 is provided with an anti-detachment limiting portion 215. When the protective door assembly 200 is not installed on the track body 100, the protective door 220 can be engaged with the anti-detachment limiting portion 215 through the hook portion 224 to prevent the protective door 220 from detaching from the door seat 210. After the protective door assembly 200 is installed on the track body 100, when the protective door 220 is in the covered position or the yielding position, the hook portion 224 is deviated from the anti-detachment limiting portion 215. With the above structure, it is possible to ensure that the protective door 220 and the door seat 210 are connected to each other and will not separate when the protective door assembly 200 is not installed in the track body 100, thereby facilitating assembly. After the protective door assembly 200 is installed in the track body 100, the hook portion 224 will not further constrain the protective door 220, thus avoiding affecting the travel of the protective door 220. When installing the protective door assembly 200 into the track body 100, the protective door 220 can be installed by slightly compressing it. In this embodiment, the anti-detachment limiting part 215 is a crossbeam structure connected to each longitudinal beam part 214, which can also strengthen the strength of the door seat 210.

[0041] In this embodiment, multiple sets of protective door assemblies 200 are provided and arranged in two rows. The two rows of protective door assemblies 200 are respectively disposed on both sides of the insertion opening 110 along its width direction. The protective doors 220 disposed on both sides of the insertion opening 110 along its width direction are correspondingly arranged opposite each other and are used to cover and open corresponding halves of the insertion opening 110, respectively. Using the above structure, the insertion opening 110 can be covered from both sides, thus the protective doors 220 do not require a large travel distance. It is conceivable that in some embodiments, a protective door 220 on one side can also be used to cover and open the insertion opening 110.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
