Abstract

This invention relates to a method for fixing an extension cord socket. At least one first coupling member and at least one freely detachable synchronous clamp are provided in the extension cord socket. Each freely detachable synchronous clamp includes a fixing unit and a movable pad. The fixing unit includes a first plate, a connector, and a second plate. The first plate, connector, and second plate form a first clamping space with each other. A second coupling member is provided on the first plate, and the second coupling member includes a limiting member. The first plate and the second plate together possess a clamping force in an axial direction. The movable pad is coupled to the first plate, and the first plate can be displaced relative to the movable pad in the same axial direction.

This allows the second clamping space to be adjusted synchronously and securely clamp the extension cord socket.

Description

[Technical Field]

[0001] The present invention relates to a method for fixing an extension cord socket, specifically to an invention that enables a free-loading synchronous clamp to have a first clamping space and a second clamping space, wherein when the first clamping space clamps an external object (e.g., a table), the second clamping space can be synchronously adjusted to securely clamp the extension cord socket. [Previous Technology]

[0002] In order to facilitate use on the desktop, in addition to placing the extension cord socket directly on the desktop, in order to prevent it from falling due to collision or to facilitate plugging and unplugging of electrical equipment, the extension cord socket is combined with a fixing device to fix the extension cord socket to the desktop.

[0003] Chinese Patent No. CN210224478U, "A Rotatable Table-Clamping Multi-Hole Socket," describes a method for fixing the socket body to a desktop. Besides using a clamping base and clamping plates to clamp the desktop, a support frame is also needed to secure the socket body. The socket body and support frame are fixed together using screws and nuts, while the support frame and clamping base are connected by a pivot. In other words, the support frame needs to be fixed to the socket body with screws and nuts, and also to the clamping base with a pivot, making the fixing process overly complicated.

[0004] Chinese Patent No. CN214706483U "Integrated Socket" uses a fixing frame to clamp the desktop. The socket is fixed to the V-shaped plate of the fixing frame by two screws. The fixing hole of the socket is set on the bottom shell, and the bottom shell is then combined and fixed with the top cover and end cover. With this fixing method, the socket cannot be easily removed from the V-shaped plate. When the socket is moved away from the V-shaped plate of the fixing frame, the socket will carry the V-shaped plate with it, which makes the placement of the socket cumbersome.

[0005] Taiwan Patent No. 496597, "Fixing Member for Extension Cord Socket (Additional Component)," utilizes a plate pivotally connected to the extension cord socket body to form a clamp, thereby securing the extension cord socket to a tabletop. In this case, the extension cord socket and the clamp are integrated and cannot be disassembled for use as a regular extension cord socket. [Summary of the Invention]

[0006] This invention proposes a method for fixing an extension cord socket, comprising the following steps:

[0007] At least one first coupling member is provided in an extension cord socket, each of the first coupling members having a coupling thickness. At least one free-loading and detachable synchronous clamp is provided, each of the free-loading and detachable synchronous clamps having a fixing unit, the fixing unit including a first plate, a connector and a second plate, the first plate, the connector and the second plate forming a first clamping space with each other, and the first plate and the second plate jointly possessing a clamping force. A second coupling member is fixedly provided on the first plate, and the second coupling member also fixes a limiting member. Each free-loading and detachable synchronous clamp has a movable pad, the movable pad being disposed on the first plate, allowing the first plate to move relative to the movable pad in the direction of the clamping force, and forming a second clamping space between the movable pad and the limiting member. The second coupling member is detachably coupled to the first coupling member, and the coupling thickness is located in the second clamping space.

[0008] Using the clamping force, an external object is clamped in the first clamping space. The clamping force causes the first plate to move relative to the movable pad, thereby reducing the second clamping space and simultaneously clamping the bonding thickness, thereby fixing the extension cord socket to the external object.

[0009] Further, a clamping rod is screwed onto the second plate of the fixing unit. The clamping rod has an operating end and a clamping end, such that the operating end is located outside the first clamping space and the clamping end is located in the first clamping space. By rotating the clamping rod, the clamping end is moved toward or away from the second plate to increase or decrease the clamping force.

[0010] Further, the first plate, the connector and the second plate are configured as an integrally formed C-shaped clamp.

[0011] Further, the first connecting member is a groove disposed on a housing of the extension socket, the groove including an inlet and a sliding section, the housing having the aforementioned connecting thickness in the sliding section; the second connecting member is an upright tenon with a head, the head of the tenon forming the aforementioned limiting member, the head being used to enter or leave the groove from the inlet, and the head being restricted in the sliding section and unable to detach from the groove.

[0012] Further, the movable pad includes an outer component and an inner component, the outer component is located outside the first clamping space, and the inner component extends into the first clamping space; the outer component and the aforementioned limiting member form the second clamping space, and the inner component is used to contact the foreign object.

[0013] Further, the first plate and the second plate are configured in a scissor-like shape, the connector is used to pivotally connect the first plate and the second plate, and an elastic element is provided to give the first plate and the second plate the clamping force.

[0014] Further, the first plate extends vertically to form a first fitting portion, and the second plate extends vertically to form a second fitting portion. The first fitting portion and the second fitting portion fit together to form the aforementioned connecting member. A tensile elastic element is provided between the first fitting portion and the second fitting portion to impart the clamping force to the first plate and the second plate.

[0015] Further, the extension cord socket extends along a longitudinal direction, and a plurality of the first couplings are distributed along the longitudinal direction. Two or more of the fixing units are respectively coupled to different first couplings through the second couplings, so that the extension cord socket is fixed to the external object.

[0016] The following effects can be achieved based on the above technical features:

[0017] 1. A movable pad is attached to the first plate of the fixed unit of the free loading and unloading synchronous clamp, and a displacement gap is reserved in the movable space of the movable pad. When the extension socket is fixed to the table or other external objects, the first plate can be moved in the movable space simultaneously to eliminate the gap between the extension socket and the free loading and unloading synchronous clamp. In addition to making the free loading and unloading synchronous clamp clamp tightly clamped to the table, the extension socket can also be clamped tightly to the free loading and unloading synchronous clamp at the same time.

[0018] 2. By using two or more freely detachable synchronous clamps to fix the extension cord socket to the table in the longitudinal direction, the extension cord socket can be made more stable and will not shift due to external force.

[0019] 3. The free-loading synchronous clamp and the extension socket are connected in a movable manner. When the extension socket is equipped with multiple first connecting parts (i.e., slides), any free-loading synchronous clamp can be connected to the most suitable slide position on the extension socket according to the needs of the installation environment to obtain the best fixing effect.

[0020] 4. When it is necessary to remove the extension cord socket from the table or other external objects and remove the free-loading synchronous clamp from the extension cord socket (for example, to change the engagement position of the free-loading synchronous clamp in the extension cord socket or to use the extension cord socket in general), simply release the clamping force on the table in the first clamping space (for example, by rotating the clamping rod to release the clamping end from the table) to simultaneously release the second clamping space that clamps the extension cord socket. Then, the extension cord socket can be removed from the table or other external objects. Then, the second engagement part (i.e., the tenon with the head) of the free-loading synchronous clamp is operated in the opposite direction to the engagement direction with the first engagement part (i.e., the groove) of the extension cord socket. The free-loading synchronous clamp can be easily removed without the use of tools.

Implementation Method

[0021] The following embodiments are only for illustrating the fixing method of the extension cord socket of the present invention, and are not intended to limit the present invention.

[0022] Referring to the first and second figures, this embodiment includes an extension cord socket 1 and two freely detachable synchronous clamps 2.

[0023] The extension cord socket 1 includes a plurality of AC power sockets and / or DC power sockets (not shown in the figure), and a plurality of first couplings arranged at intervals between each other. In this embodiment, the first coupling is a groove 11. The extension cord socket 1 extends along a longitudinal direction D, and the plurality of the aforementioned AC power sockets and / or DC power sockets are arranged at intervals along the longitudinal direction D. Each of the first couplings (grooves 11) is also arranged at intervals along the longitudinal direction D.

[0024] Each of the aforementioned free-loading and unloading synchronous clamping seats 2 has a fixing unit and a movable pad 4. In this embodiment, the fixing unit includes an open seat 21 and a clamping rod 22. The open seat 21 has a first plate 211, a second plate 212, and a connector connecting the first plate 211 and the second plate 212. In this embodiment, the connector is an integrally formed side plate 213 connecting the first plate 211 and the second plate 212, making the fixing unit an integrally formed C-shaped clamp. A second connecting member is provided on the first plate 211. In this embodiment, the second connecting member corresponds to a tenon 24 with a head on the aforementioned slide groove 11. The second connecting member (tenon 24 with a head) corresponds to... The aforementioned first connecting member (slide groove 11) can be assembled and disassembled together. The first plate 211, the second plate 212, and the side plate 213 surround and define a first clamping space 23. The clamping rod 22 extends into the first clamping space 23 from the outside of the second plate 212. Specifically, the clamping rod 22 has an operating end 221 and a clamping end 222. The clamping end 222 is located in the first clamping space 23. A threaded rod 223 connects the operating end 221 and the clamping end 222. The threaded rod 223 is screwed into the second plate 212 of the opening seat 21. The aforementioned movable gasket 4 is attached to the first plate 211.

[0025] Each of the free-loading synchronous clamps 2 is connected to different first couplings (slide grooves 11) by the second coupling (head tenon 24), so that each of the free-loading synchronous clamps 2 is detachably fixed to the extension socket 1 at different positions in the longitudinal direction D.

[0026] Referring to Figures 1, 3 to 5, the slide groove 11 of the extension cord socket 1 has an inlet 111 and a sliding section 112 connected to the inlet 111. The tenon 24 of the detachable synchronous clamp 2 has a head 241 and a neck 242. The maximum width of the head 241 is smaller than the inlet 111 but larger than the sliding section 112. The head 241 is inserted into the slide groove 11 through the inlet 111 and slides on the sliding section 112 with the neck 242. The head 241 is restricted in the sliding section 112 and cannot be removed from the slide groove 11, so that the detachable synchronous clamp 2 is fitted and fixed on the extension cord socket 1.

[0027] Referring to Figures 6 to 9, the free-loading synchronous clamp 2 is moved laterally into the periphery of a tabletop 3, so that the periphery of the tabletop 3 enters the first clamping space 23 of the opening seat 21 until the periphery of the tabletop 3 abuts against the side plate 213 of the opening seat 21. Then, the operating end 221 of the clamping rod 22 is rotated, and the threaded rod 223 is screwed into the first clamping space 23 along the axial direction P until the clamping end 222 clamps the lower edge of the tabletop 3 and provides a clamping force between the first plate 211 and the second plate 212 along the axial direction P to clamp the tabletop 3, thereby fixing the extension cable socket 1 to the tabletop 3 through the free-loading synchronous clamp 2.

[0028] The movable pad 4 includes an outer component and an inner component. The outer component is located outside the first clamping space 23, and the inner component extends into the first clamping space 23. In this embodiment, the outer component is a first pad 41, and the inner component is a second pad 42. The first pad 41 and the second pad 42 surround to form a movable space 43. The movable space 43 has a movable width D1 between the first pad 41 and the second pad 42. The first plate 211 extends into the movable space 43 so that the movable pad 4 fits onto the first plate 211. The movable width D1 is greater than the thickness T of the first plate 211, so that the first plate 211 has a displacement distance D2 along the axial direction P in the movable space 43. The second coupling (head tenon 24) includes a limiting member, which in this embodiment is the head 241 of the head tenon 24. A second clamping space 25 is defined between the first gasket 41 and the limiting member (head 241 of the head tenon 24).

[0029] In detail, the extension cord socket 1 has a housing 10, and the slide groove 11 is formed on the housing 10. The housing 10 is located around the sliding section 112 and is formed by a clamping portion 101 to form a joint thickness. When the free-loading synchronous clamp 2 is assembled on the extension cord socket 1, the tenon 24 with the head is first slid into the slide groove 11. The head 241 of the tenon 24 with the head forms a gap D3 with the clamping portion 101 and / or a gap D4 is formed between the clamping portion 101 and the first gasket 41. When the extension cord socket 1 is fixed to the tabletop 3, the operating end 221 of the clamping rod 22 is rotated, and the threaded rod 223 is continuously screwed into the first clamping space 23, thereby clamping the tabletop 3 tightly through the clamping force. At the same time, the first plate 211 is simultaneously displaced towards the desktop in the movable space 43 by the reaction force of the tabletop 3, thereby reducing the second clamping space 25 and eliminating the gaps D3 and D4. At this time, the clamping end 222 of the free-loading synchronous clamping seat 2 and the second washer 42 clamp the tabletop 3 tightly, and the head 241 of the tenon 24 is tightly attached to the clamped part 101. At the same time, the clamped part 101 also tightly abuts against the first washer 41, so that the clamped part 101 is also simultaneously clamped in the second clamping space 25 by the head 241 of the tenon 24 and the first washer 41, thereby making the extension cord socket 1 firmly fixed to the tabletop 3.

[0030] Referring to Figure 10, by fixing the extension cord socket 1 to the tabletop 3 with two or more freely detachable synchronous clamps 2 along the longitudinal direction D, the extension cord socket 1 can be made more stable and will not shift or deflect due to external forces.

[0031] According to the foregoing figures, when it is necessary to remove the extension cord socket 1 from the tabletop 3 and remove the free-loading synchronous clamp 2 from the extension cord socket 1, simply rotate the clamping rod 22 to release the clamping end 222 located in the first clamping space 23 from the tabletop 3, and the second clamping space 25 clamping the extension cord socket 1 can be released simultaneously. Then the extension cord socket 1 can be removed from the tabletop 3. Then, the tenon 24 with the head can be operated in the opposite direction of the engagement with the slide groove 11, and the free-loading synchronous clamp 2 can be easily removed without the use of tools.

[0032] Referring to Figure 11, the fixing unit of the free loading and unloading synchronous clamp 2A may also include a first plate 211A and a second plate 212A. The first plate 211A extends vertically to a first fitting portion 2111A, and the second plate 212A extends vertically to a second fitting portion 2121A. The first fitting portion 2111A and the second fitting portion 2121A fit together to form the aforementioned connecting member. A tension elastic element 213A is provided between the first fitting portion 2111A and the second fitting portion 2121A. The tension elastic element 213A provides the clamping force when the free loading and unloading synchronous clamp 2A clamps an external object (such as the aforementioned table 3).

[0033] Referring to Figure 12, the fixing unit of the free loading and unloading synchronous clamp 2B may also include a first plate 211B and a second plate 212B. The first plate 211B and the second plate 212B are configured in a scissor-like shape. The connector is used to pivotally connect the first plate 211B and the second plate 212B. An elastic element 213B is provided between the first plate 211B and the second plate 212B. The elastic element 213B provides the clamping force when the free loading and unloading synchronous clamp 2B clamps an external object (such as the aforementioned table 3).

[0034] Referring to Figure 13, in this embodiment, the first gasket 41 of the movable gasket 4 has a groove 411 and the second gasket 42 has a post 421. The first gasket 41 and the second gasket 42 are embedded in the groove 411 through the post 421 to form the movable gasket 4.

[0035] Referring to Figure 14, in a variation, the movable gasket 4A includes a first gasket 41A and a second gasket 42A, which are integrally formed.

[0036] Referring to Figure 15, in another variation, the movable gasket 4B includes a first gasket 41B and a second gasket 42B. The first gasket 41B has a first locking block 411B around its periphery, and the second gasket 42B has a second locking block 421B around its periphery. The first gasket 41B and the second gasket 42B are combined to form the movable gasket 4B by engaging the second locking block 421B with the first locking block 411B.

[0037] Referring to Figures 16 and 17, taking the movable pad 4B as an example, the first pad 41B has a through hole 413B, and a plurality of positioning posts 412B are provided around the through hole 413B. The first plate 211 is provided with a plurality of positioning holes 2111. When the movable pad 4B is fitted onto the first plate 211, the tenon 24 with the head can pass through the through hole 413B, and the positioning post 412B passes through the positioning hole 2111. Referring to Figures 17 to 19, when the free-loading synchronous clamp 2 is clamped onto the table 3, the positioning post 412B can guide the first plate 211 and the movable pad 4B to maintain relative displacement on the axial direction P, thereby synchronously clamping the extension cable socket 1 onto the free-loading synchronous clamp 2.

[0038] Referring to Figures 20 and 21, in a variation, the movable pad 4C is flat, and a positioning post 41C is provided on the movable pad 4C. When the movable pad 4C is engaged with the first plate 211, the positioning post 41C passes through the positioning hole 2111 and abuts against the table 3. Referring to Figures 21 to 23, when the free-loading synchronous clamp 2 is clamped to the table 3, the positioning post 41C can guide the first plate 211 and the movable pad 4C to maintain relative displacement along the axial direction P, thereby synchronously clamping the extension cable socket 1 to the free-loading synchronous clamp 2.

[0039] Referring to Figures 24 and 25, in another variation, the movable gasket 4D includes a first gasket 41D and a second gasket 42D. The first gasket 41D and the second gasket 42D are flat. A positioning post 411D is provided on the first gasket 41D, and a positioning groove 421D is provided on the second gasket 42D. When the movable gasket 4D is attached to the first plate 211, the positioning post 411D passes through the positioning hole 2111 and extends into the positioning groove 421D, thereby making it easy to assemble and attach the first gasket 41D and the second gasket 42D to the first plate 211 from opposite sides. Referring to Figures 25 to 27, when the free-loading synchronous clamp 2 is clamped to the table 3, the positioning post 411D can guide the first plate 211 and the movable pad 4D to maintain relative displacement on the axial direction P, thereby synchronously clamping the extension cable socket 1 to the free-loading synchronous clamp 2.
