[0048] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] The first aspect of this utility model provides a safety door assembly 10, which is used in a power strip 1 and can effectively improve the safety of the power strip 1. In this solution, the power strip 1 including the safety door assembly 10 can be applied to e-sports scenarios, home office scenarios, and even industrial scenarios, especially in e-sports scenarios, as it can provide power to the electrical devices used in e-sports. It should be noted that the power strip 1 includes a base 20, and the base 20 is provided with a first socket 201. The first socket 201 can be single or multiple. The first socket 201 can be a three-prong socket, a two-prong socket, or a combination of three-prong and two-prong sockets nested together. This embodiment of the application uses a combination of nested three-prong and two-prong sockets as an example for description. It can be understood that the first socket 201 is used for plugging in a plug 30 to provide power. The following refers to... Figures 1 to 9 The following describes a safety door assembly 10 according to an embodiment of this application. Specifically, the safety door assembly 10 includes a fixed base 100 and a movable stop 200.

[0051] Reference Figures 1 to 4 and Figure 8 The fixing base 100 is used to connect to the base body 20. Specifically, the fixing base 100 can be detachably connected to the base body 20, which facilitates the installation, removal, and replacement of the safety door assembly 10. The fixing base 100 can define a receiving cavity 110, which can accommodate the movable stop 200. The receiving cavity 110 is provided with a second insertion hole 111, which communicates with the first insertion hole 201. It should be noted that the positions of the second insertion hole 111 can correspond one-to-one with the positions of the first insertion hole 201. It can be understood that when power is required, the plug 30 can pass through the second insertion hole 111 and then be plugged into the first insertion hole 201 to obtain electrical energy.

[0052] Reference Figures 2 to 8 The movable stop 200 is used to lock or release the second socket 111. Specifically, the movable stop 200 can be accommodated within the receiving cavity 110 and connected to the fixed base 100. The movable stop 200 has a first position and a second position relative to the fixed base 100. When the movable stop 200 is in the first position, it can at least partially block the second socket 111, thus preventing electric shock caused by a person holding a non-conductive electrode and directly inserting it into the second socket 111 and the first socket 201 without a safety shield. When the movable stop 200 is in the second position, the second socket 111 is exposed relative to the movable stop 200, meaning the plug 30 can be normally inserted into the second socket 111 and the first socket 201 to obtain electrical energy.

[0053] Reference Figures 5 to 8 The specific relative movement settings between the movable stop 200 and the fixed base 100 are described below. To facilitate description and understanding of the specific movement direction of the movable stop 200, the axial direction of the second socket 111 is used as a reference, for example. (Refer to...) Figure 6 The second socket 111 can be oriented in a front-back direction, and the movable stop 200 can move relative to the fixed base 100 along a direction perpendicular to the axis of the second socket 111. That is, the movable stop 200 can move relative to the fixed base 100 in a left-right direction to switch from the first position to the second position, thereby releasing the second socket 111. The specific direction of movement of the movable stop 200 can be determined according to the actual situation.

[0054] Reference Figure 5 , Figure 8 and Figure 9 The fixed base 100 is provided with a first connecting structure 120, and the movable stop 200 is provided with a second connecting structure 210. The specific structure of the second connecting structure 210 may differ from that of the first connecting structure 120. The first connecting structure 120 can cooperate with the second connecting structure 210 to restrict the movable stop 200 from disengaging from the fixed base 100, thereby improving the reliability of the assembly connection between the movable stop 200 and the fixed base 100. For example, the first connecting structure 120 and the second connecting structure 210 can restrict the movable stop 200 from directly disengaging from the fixed base 100 along an axis parallel to the second insertion hole 111.

[0055] In the technical solution of this utility model, the safety gate assembly 10 is used in the power strip 1. The socket 20 of the power strip 1 is provided with a first socket 201, which is used for plugging in the plug 30 to provide power. The safety gate assembly 10 includes a fixed base 100 and a movable stop 200. The fixed base 100 is used to connect to the base and define a receiving cavity 110, which is provided with a second socket 111. The movable stop 200 is housed in the receiving cavity 110 and connected to the fixed base 100. In related technologies, power strips include a base with sockets for plugging in to provide power. However, if a child inserts a conductive object into the socket, it can cause an accidental electric shock, indicating poor safety of power strips. The movable stop 200 of this design has a first position and a second position relative to the fixed base 100. In the first position, the movable stop 200 at least partially blocks the second socket 111, meaning that the movable stop 200 can prevent a different conductor from being inserted into the second socket 111. Since the second socket 111 is conductive to the first socket 201, accidental electric shock can be effectively avoided, significantly improving the safety of using the power strip 1. In the second position, the second socket 111 is exposed relative to the movable stop 200, meaning that the plug 30 can normally pass through the second socket 111 and be inserted into the first socket 201 to provide power.

[0056] Furthermore, the movable stop 200 can move relative to the fixed base 100 along an axis perpendicular to the second socket 111 to switch from the first position to the second position. This means the position switching operation of the movable stop 200 is convenient and quick, meeting the application needs of multiple scenarios and improving user experience. Moreover, compared to the solution where the movable stop 200 is directly placed in the receiving cavity 110 of the fixed base 100, this solution provides a first connecting structure 120 for the fixed base 100 and a second connecting structure 210 for the movable stop 200. The cooperation of the first connecting structure 120 and the second connecting structure 210 restricts the movable stop 200 from detaching from the fixed base 100 along an axis parallel to the second socket 111, effectively preventing the movable stop 200 from accidentally detaching from the fixed base 100 and causing blocking failure. This improves the stability of the assembly connection between the movable stop 200 and the fixed base 100, ensuring the reliability of power supply.

[0057] Reference Figure 4 , Figure 5 , Figure 8 and Figure 9 The specific connection configuration of the first connecting structure 120 and the second connecting structure 210 is described below. In some embodiments, the second connecting structure 210 includes a first guide protrusion 211, and the first connecting structure 120 includes a first sliding groove 121. To facilitate description and understanding of the specific configuration of the first sliding groove 121, a first direction X is defined, and the first sliding groove 121 can extend along the first direction X. The first direction X is perpendicular to the axial direction of the second insertion hole 111, referring to... Figure 8 In terms of orientation, the first sliding groove 121 can extend in the left-right direction. In other embodiments, the first connecting structure 120 includes a first guide protrusion 211, and the second connecting structure 210 includes the first sliding groove 121. This application embodiment is described using the example of the second connecting structure 210 including the first guide protrusion 211 and the first connecting structure 120 including the first sliding groove 121.

[0058] The first guide protrusion 211 can be arranged through the first slide groove 121. During the process of the movable stop 200 switching from the first position to the second position, the first guide protrusion 211 can slide in the first slide groove 121 along the first direction X. That is, the first guide protrusion 211 and the first slide groove 121 cooperate in this solution, which can effectively prevent the movable stop 200 from separating from the fixed seat 100 and improve the stability of the assembly connection between the movable stop 200 and the fixed seat 100.

[0059] Reference Figure 4 , Figure 5 , Figure 8 and Figure 9In some embodiments, the second connecting structure 210 includes a second guide protrusion 212. The structure of the second guide protrusion 212 may be the same as that of the first guide protrusion 211, or it may have a different structure. To facilitate description and understanding of the relative arrangement of the second guide protrusion 212 and the first guide protrusion 211, a second direction Y is defined. The second guide protrusion 212 and the first guide protrusion 211 are arranged opposite each other along the second direction Y. The second direction Y is perpendicular to the first direction X and the axial direction of the second insertion hole 111. (Refer to...) Figure 5 The orientation is as follows: the first direction X can point to the left or right, and the second direction Y can point to the up or down. The first connecting structure 120 includes a second slide groove 122, the structure of which can be the same as or different from that of the first slide groove 121. The second slide groove 122 and the first slide groove 121 are arranged opposite to each other along the second direction Y.

[0060] In other embodiments, the second connecting structure 210 includes a second sliding groove 122, and the first connecting structure 120 includes a second guide protrusion 212. The specific arrangement of the first connecting structure 120 and the second connecting structure 210 can be determined according to the actual situation. In this embodiment, the second connecting structure 210 includes the second guide protrusion 212, and the first connecting structure 120 includes the second sliding groove 122 as an example. The second guide protrusion 212 can be arranged through the second sliding groove 122. When the movable stop 200 switches from the first position to the second position, the second guide protrusion 212 can slide in the second sliding groove 122 along the first direction X. That is, the second guide protrusion 212 and the second sliding groove 122 of this solution cooperate to effectively improve the stability of the relative movement between the movable stop 200 and the fixed seat 100 and the reliability of the assembly connection, and effectively prevent the movable stop 200 from disengaging from the fixed seat 100.

[0061] Reference Figures 4 to 9 The following describes the specific limiting settings of the fixed base 100 on the movable stop 200. In some embodiments, the movable stop 200 is provided with a first limiting part 220, and the fixed base 100 is provided with a second limiting part 130. The first limiting part 220 can cooperate with the second limiting part 130 to prevent the movable stop 200 from directly disengaging from the fixed base 100 along an axis parallel to the first insertion hole 201. (Refer to...) Figure 6 The orientation, that is, the first limiting part 220 can cooperate with the second limiting part 130, thereby restricting the movable stop 200 from disengaging from the receiving cavity 110 of the fixed seat 100 in the front-back direction, ensuring the reliability of the assembly connection between the fixed seat 100 and the movable stop 200. It should be noted that the movable stop 200 may be provided with a clearance hole, and the first limiting part 220 of the fixed seat 100 may pass through the clearance hole and be located on the side of the first limiting part 220 opposite to the seat body 20.

[0062] Furthermore, in some embodiments, the first limiting part 220 includes a flange, and the second limiting part 130 includes a hook. The flange of the first limiting part 220 can cooperate with the hook of the second limiting part 130 to restrict the movable stop 200. In other embodiments, the first limiting part 220 includes a hook, and the second limiting part 130 includes a flange. The hook of the first limiting part 220 can cooperate with the flange of the second limiting part 130 to restrict the movable stop 200. The specific structure of the first limiting part 220 and the second limiting part 130 can be determined according to the actual situation. In this embodiment, the movable stop 200 is provided with a flange, and the fixed base 100 is provided with a hook, as an example for description.

[0063] Reference Figures 4 to 9 The specific movement configuration of the movable stop 200 and the fixed base 100 is described below. In some embodiments, the movable stop 200 is provided with a connecting hole 230, and the fixed base 100 includes a first connecting block 140 and a second connecting block 150. The first connecting block 140 and the second connecting block 150 are spaced apart along a first direction X and arranged opposite to each other. The first direction X is perpendicular to the axis of the second insertion hole 111. It can be understood that both the first connecting block 140 and the second connecting block 150 pass through the connecting hole 230. The safety door assembly 10 includes an elastic member 300, and the two ends of the elastic member 300 are respectively connected to the first connecting block 140 and the second connecting block 150. Specifically, the first connecting block 140 is provided with a first connecting protrusion facing the second connecting block 150, and the second connecting block 150 is provided with a second connecting protrusion facing the first connecting block 140. The two ends of the elastic member 300 can be respectively sleeved on the first connecting protrusion and the second connecting protrusion.

[0064] When the movable stop 200 is in the second position and the plug 30 is disengaged from the second socket 111, the elastic element 300 can drive the movable stop 200 to slide along the first direction X to the first position, thereby blocking the second socket 111. During the insertion of the plug 30 into the second socket 111, the plug 30 can drive the movable stop 200 to switch from the first position to the second position in the opposite direction X, allowing the second socket 111 to be exposed for normal connection and power acquisition. In other words, the movable stop 200 of this solution can release the second socket 111 when the plug 30 is inserted, and reset to block the second socket 111 when the plug 30 is disengaged via the elastic element 300, making the overall position switching operation convenient and quick. Compared to the solution where the elastic element is fixedly connected to the movable stop, this solution can prevent the elastic element 300 from detaching from the movable stop 200 when the movable stop 200 warps on one side, improve the stability of the assembly connection between the elastic element 300, the fixed seat 100, and the movable stop 200, and ensure the reliability of the elastic element 300 driving the movable stop 200.

[0065] Reference Figure 4The specific structural configuration of the second socket 111 is described below. In some embodiments, the second socket 111 includes a two-pronged socket 1111 and a three-pronged socket 1112, which are arranged nested together. The plug 30 includes a separately arranged two-pronged insert and a three-pronged insert 301. During the insertion of the two-pronged insert into the two-pronged socket 1111, the two-pronged insert can drive the movable stop 200 to slide along the first direction X to block the three-pronged socket 1112, preventing electric shock caused by inserting a foreign conductive object into the three-pronged socket 1112. During the insertion of the three-pronged insert 301 into the three-pronged socket 1112, the three-pronged insert 301 can drive the movable stop 200 to slide in the opposite direction of the first direction X to block the two-pronged socket 1111, preventing electric shock caused by inserting a foreign conductive object into the two-pronged socket 1111. The second socket 111 of this solution includes a three-prong socket 1112 and a two-prong socket 1111, which can improve the compatibility of the power strip 1 and meet various charging needs. In the process of inserting the three-prong plug 301 into the three-prong socket 1112 or the two-prong plug into the two-prong socket 1111, the movable block 200 can be driven to block the non-target socket, which can ensure the safety of the power strip 1 and prevent accidental electric shock.

[0066] Reference Figures 3 to 7 The specific structural configuration of the movable stop 200 is described below. In some embodiments, the movable stop 200 includes a first inclined wall 240, which is located on the side of the movable stop 200 opposite to the first socket 201. It can be understood that the first inclined wall 240 can be inclined relative to the axial direction of the second socket 111. During the process of inserting the two-prong plug into the two-prong socket 1111, the two-prong plug can press against the first inclined wall 240, so that the movable stop 200 slides along the first direction X until the two-prong socket 1111 is exposed, allowing the two-prong plug to be normally connected to obtain power. In this solution, the first inclined wall 240 of the movable stop 200 can convert the vertical insertion operation of the plug 30 into the lateral movement of the movable stop 200, that is, it can eliminate the need for additional drive settings for the movable stop 200, optimize the overall structural layout, and ensure the safety of the power strip 1.

[0067] Reference Figures 3 to 7The movable stop 200 includes a second inclined wall 250, which is located on the side of the movable stop 200 opposite to the first socket 201. The second inclined wall 250 can be spaced apart from the first inclined wall 240. During the insertion of the three-prong plug 301 into the three-prong socket 1112, the three-prong plug 301 can press against the second inclined wall 250, causing the movable stop 200 to slide in the opposite direction of the first direction X until the three-prong socket 1112 is exposed, allowing the three-prong plug 301 to be properly connected and obtain power. In this solution, the second inclined wall 250 of the movable stop 200 can convert the vertical insertion operation of the plug 30 into the lateral movement of the movable stop 200, thus eliminating the need for additional drive settings for the movable stop 200, optimizing the overall structural layout, and ensuring the safety of the power strip 1.

[0068] Reference Figures 4 to 9 The specific driving configuration of the elastic element 300 for the movable stop 200 is described below. In some embodiments, the connecting hole 230 is provided with a first boss 231 and a second boss 232, which are arranged opposite to each other along the first direction X. When the three-prong plug 301 disengages from the three-prong socket 1112, the compressed elastic element 300 can press against the first boss 231, causing the movable stop 200 to move along the first direction X to block the three-prong socket 1112, thereby locking the three-prong socket 1112. When the two-prong plug disengages from the two-prong socket 1111, the compressed elastic element 300 can press against the second boss 232, causing the movable stop 200 to move in the opposite direction of the first direction X to block the two-prong socket 1111, thereby locking the two-prong socket 1111. The elastic element 300 of this solution cooperates with the first boss 231 and the second boss 232, which can not only improve the stability of the elastic element 300 during installation and removal, but also adapt to the insertion operation of the three-prong plug 301 and the two-prong plug. Compared with the solution of locking the three-prong plug and the two-prong plug by moving the elastic element in the same direction, the elastic element 300 of this solution can directly drive the movable stop 200 in both directions, effectively shortening the driving stroke and ensuring the reliability of blocking and limiting the second socket 111.

[0069] Reference Figure 3 and Figure 9 In some embodiments, the movable stop 200 is provided with a plurality of protrusions 260, each of which is used to abut against the fixing seat 100. Specifically, along the axial direction parallel to the first insertion hole 201, each protrusion 260 extends toward the fixing seat 100, as shown in the figure. Figure 4In terms of orientation, each protrusion 260 can extend from top to bottom. It can be understood that the protruding extension length of each protrusion 260 can be equal. This design, by having multiple protrusions 260 abut against the fixed seat 100, effectively reduces the contact area between the movable stop 200 and the fixed seat 100, improves the smoothness of the movement of the movable stop 200 relative to the fixed seat 100, and reduces sliding resistance.

[0070] The second aspect of this utility model provides a power strip 1, such as... Figures 1 to 3 As shown, the power strip 1 includes the safety door assembly 10 and the base 20 of the above embodiment. The base 20 is provided with a first socket 201, and the base 20 is detachably connected to the fixing seat 100 of the safety door assembly 10. The first socket 201 is used for plugging in the plug 30 to provide power. It should be noted that the power strip 1 may be provided with a panel 40, which may cover the safety door assembly 10. The movable stop 200 of this solution has a first position and a second position relative to the fixing seat 100. In the first position, the movable stop 200 at least partially blocks the second socket 111, that is, the movable stop 200 can prevent a different conductor from being inserted into the second socket 111. Since the second socket 111 is conductive to the first socket 201, accidental electric shock can be effectively avoided, greatly improving the safety of using the power strip 1. In the second position, the second socket 111 is exposed relative to the movable stop 200, that is, the plug 30 can pass through the second socket 111 and be plugged into the first socket 201 to provide power. Furthermore, the movable stop 200 can move relative to the fixed base 100 along an axis perpendicular to the second socket 111 to switch from the first position to the second position. This means the position switching operation of the movable stop 200 is convenient and quick, meeting the application needs of multiple scenarios and improving user experience. Moreover, compared to the solution where the movable stop 200 is directly placed in the receiving cavity 110 of the fixed base 100, this solution provides a first connecting structure 120 for the fixed base 100 and a second connecting structure 210 for the movable stop 200. The cooperation of the first connecting structure 120 and the second connecting structure 210 restricts the movable stop 200 from detaching from the fixed base 100 along an axis parallel to the second socket 111, effectively preventing the movable stop 200 from accidentally detaching from the fixed base 100 and causing blocking failure. This improves the stability of the assembly connection between the movable stop 200 and the fixed base 100, ensuring the reliability of power supply.

[0071] The specific connection arrangement between the base 20 and the fixed base 100 is described below. In some embodiments, the fixed base 100 is provided with a connecting hook 160, which can be engaged with the locking position of the base 20, improving the stability of the assembly connection between the fixed base 100 and the base 20. In other embodiments, the fixed base 100 is provided with a guide plate 170, which can pass through the opening of the base 20, improving the assembly connection accuracy between the fixed base 100 and the base 20. In other embodiments, the fixed base 100 is provided with multiple connecting hooks 160 and multiple guide plates 170, and the connecting hooks 160 can be arranged adjacent to the guide plates 170. This application embodiment uses a fixed base 100 with two connecting hooks 160 and two guide plates 170 as an example for explanation.

[0072] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0073] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
