Description

Technical Field

[0001] This disclosure pertains to the field of electronic devices, and particularly relates to a locking mechanism, a socket, and a table. Background Technology

[0002] A socket is a common electronic device used to plug in electrical equipment, thereby providing power to the equipment.

[0003] In related technologies, there is a recessed socket that can be fitted into a hole in a carrier (such as a table, wall, etc.). This recessed socket is equipped with screws, which are used to securely mount the socket to the carrier.

[0004] However, screws can cause extensive damage to the surface of the carrier, and if the socket is removed, the damaged area will be exposed. Summary of the Invention

[0005] This disclosure provides a locking mechanism, a socket, and a table, which can prevent large-area damage to the surface of the carrier when fixing the socket on it. The technical solution is as follows:

[0006] In a first aspect, embodiments of this disclosure provide a locking mechanism, including a housing, a hook, a driving member, and a pushing member;

[0007] The hook is at least partially located within the housing and is movable relative to the housing;

[0008] Both the driving component and the pushing component are located inside the housing. The pushing component is connected to the driving component in a transmission manner, and the pushing component is in contact with the hook.

[0009] The drive element is configured to drive the push element to move such that the push element drives a portion of the hook to extend out of the housing.

[0010] In one implementation of this disclosure, the hook includes a support portion and a snap-fit ​​portion;

[0011] The support portion is located inside the housing and contacts both the inner wall of the housing and the pushing member.

[0012] The latching part is connected to the supporting part. The latching part can extend out of the housing under the action of the supporting part, or it can retract into the housing under its own weight.

[0013] In another implementation of this disclosure, the support portion includes a connecting plate and a support plate that are connected at an angle to each other;

[0014] The two sides of the support plate are in sliding contact with the inner wall of the shell, respectively.

[0015] When the support is in the first position, the pusher and the connecting plate are spaced apart from each other, and the side of the connecting plate away from the support plate tilts downward in the direction toward the pusher. The locking part is located inside the housing. When the support is in the second position, the pusher abuts against the connecting plate, and the locking part extends out of the housing.

[0016] In another implementation of this disclosure, the inner wall of the housing has a first support surface and a second support surface that are connected at an angle to each other;

[0017] The side of the support plate closest to the connecting plate slides in contact with the first support surface, and the side of the support plate furthest from the connecting plate slides in contact with the second support surface. The support plate is rotatably located between the first support surface and the second support surface, so that the support part can switch between a first position state and a second position state.

[0018] In yet another implementation of this disclosure, the driving component is a bolt;

[0019] The bolt is rotatably connected to the housing and passes through the support and the pusher respectively, and the bolt is threadedly engaged with the pusher;

[0020] When the bolt drives the pusher to move relative to the housing toward the support, the snap-fit ​​portion extends out of the housing.

[0021] In another implementation of this disclosure, the support portion has an oblong hole;

[0022] The length direction of the waist-shaped hole is on the same plane as the rotation trajectory of the support part, and the bolt is inserted into the waist-shaped hole.

[0023] In another implementation of this disclosure, the pushing member includes a substrate and a pusher plate;

[0024] The push plate is connected to the side of the base plate facing the support portion;

[0025] The substrate is connected to the bolt.

[0026] In another implementation of this disclosure, the pushing component further includes a flap;

[0027] The flap is connected to the push plate, and the side of the flap facing the base plate slides in contact with the snap-fit ​​part;

[0028] When the bolt drives the pusher to move away from the support relative to the housing, the push plate drives the snap-fit ​​portion to retract the housing.

[0029] In another implementation of this disclosure, the hook is a metal structural component.

[0030] Secondly, this disclosure provides a socket, including a socket body and the aforementioned locking mechanism;

[0031] The locking mechanism is located on opposite sides of the socket body.

[0032] In one implementation of this disclosure, the outer wall of the socket body has a socket opening;

[0033] The locking mechanism is inserted into the socket.

[0034] Thirdly, embodiments of this disclosure provide a table, including a desktop and the socket described above;

[0035] The desktop has holes;

[0036] The socket is fitted into the hole, and the hook abuts against the wall of the hole.

[0037] The beneficial effects of the technical solutions provided in this disclosure are:

[0038] When the locking mechanism provided in this embodiment is assembled into a socket, the hook is located inside the housing in a normal state. In this state, the locking mechanism can be placed into the hole on the carrier along with the socket. After placement, a driving member drives a pushing member to move, thereby causing the pushing member to drive a portion of the hook to extend out of the housing. The hook extending out of the housing is embedded in the wall of the hole, thus fixing the locking mechanism and the socket together in the hole. When it is necessary to remove the socket from the hole, the driving member is loosened, so that the driving member no longer applies external force to the hook through the pushing member, and the hook can be reset, that is, it retracts into the housing and is no longer embedded in the wall of the hole.

[0039] Since the hook only embeds into the wall of the hole, and the wall of the hole is located inside the carrier and is not easily seen, even if the socket is removed, the damaged parts caused by the hook will not be exposed. Attached Figure Description

[0057] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0058] A socket is a common electronic device used to plug in electrical equipment, thereby providing power to the equipment.

[0059] In related technologies, there is a recessed socket that can be fitted into a hole in a carrier (such as a table, wall, etc.). This recessed socket is equipped with screws, which are used to securely mount the socket to the carrier.

[0060] However, screws will drill holes in the surface of the carrier, causing extensive damage to the surface. If the socket is removed, the damaged area will be exposed.

[0061] To address the aforementioned technical problems, this disclosure provides a locking mechanism. Figure 1 See the schematic diagram of the locking mechanism. Figure 1 In this embodiment, the locking mechanism includes a housing 10, a hook 20, a driving member 30, and a pushing member 40.

[0062] The hook 20 is at least partially located within the housing 10 and is movable relative to the housing 10. Both the drive member 30 and the push member 40 are located within the housing 10, with the push member 40 being drive-connected to the drive member and in contact with the hook 20.

[0063] The drive member 30 is configured to drive the push member 40 to move such that the push member 40 drives a portion of the hook 20 to extend out of the housing 10.

[0064] Figure 2 and Figure 3 This is a schematic diagram of the locking mechanism's operation, combined with... Figure 2 and Figure 3 In this embodiment, the locking mechanism provided in this disclosure is assembled into the socket. In the normal state, the hook 20 is located inside the housing 10 (see...). Figure 2 In this state, the locking mechanism can be inserted into the hole on the carrier along with the socket. After being placed in place, the driving member 30 drives the pushing member 40 to move, thereby causing the pushing member 40 to drive a portion of the hook 20 to extend out of the housing 10 (see...). Figure 3 The hook 20 extending from the housing 10 engages with the wall of the hole, thus securing the locking mechanism and the socket together within the hole. When it is necessary to remove the socket from the hole, the drive member 30 is loosened, so that the drive member 30 no longer applies external force to the hook 20 through the push member 40, and the hook 20 can reset, that is, retract into the housing 10 and no longer engage with the wall of the hole.

[0065] Since the hook 20 is only embedded in the wall of the hole, and the wall of the hole is located inside the carrier and is not easily seen, even if the socket is removed, the damaged part caused by the hook 20 will not be exposed.

[0066] Figure 4 This is a structural diagram of the hook 20, combined with... Figure 4 In this embodiment, the hook 20 includes a support portion 210 and a snap-fit ​​portion 220.

[0067] The support portion 210 is located inside the housing 10 and contacts the inner wall of the housing 10 and the pusher 40 respectively. The snap-fit ​​portion 220 is connected to the support portion 210.

[0068] In some examples, the snap-fit ​​portion 220 can extend out of the housing 10 under the action of the support portion 210.

[0069] In the above implementation, the inner wall of the housing 10 provides a support base for the support part 210. The support part 210 is used to cooperate with the pusher 40 so that the support part 210 can move with the inner wall of the housing 10 as a fulcrum under the drive of the pusher 40, thereby driving the locking part 220 to move together, and thus causing the locking part 220 to extend out of the housing 10.

[0070] In other examples, the snap-fit ​​part 220 can retract the housing 10 under its own weight.

[0071] In the above implementation, the inner wall of the housing 10 provides a supporting base for the support portion 210. When the locking portion 220 extends out of the housing 10, the center of gravity of the locking portion 220 is outside the housing 10. As a result, the locking portion 220 tends to retract into the housing 10 under its own weight. When the support portion 210 no longer drives the locking portion 220 to extend, the locking portion 220 naturally retracts into the housing 10 under its own weight.

[0072] For example, the latching part 220 and the support part 210 are both located on the same side of the rotation axis of the support part 210. In this way, the latch 20 becomes a lever-like structural member. The part of the support part 210 that abuts against the inner wall of the housing 10 is the fulcrum of the lever. When the support part 210 is lifted by the pusher 40, the latching part 220 also tilts upward, causing the latching part 220 to extend out of the housing 10. When the support part 210 is no longer lifted, the latching part 220 falls down under the action of gravity, causing the latching part 220 to retract into the housing 10.

[0073] To facilitate the insertion of the snap-fit ​​part 220 into the carrier, the snap-fit ​​part 220 may be a hook-shaped structural component, a serrated structural component, etc., and this disclosure does not limit it in this way.

[0074] In some examples, the support 210 and the snap-fit ​​220 are integral structural components, which ensures the structural integrity of the snap hook 20, improves the structural strength of the snap hook 20, and also helps to improve the manufacturing efficiency of the snap hook 20.

[0075] In some examples, the hook 20 is a metal structural component, which effectively ensures the structural strength of the hook 20, allowing it to be embedded within the carrier. When the support portion 210 and the latching portion 220 are an integral structural component, the hook 20 is a sheet metal part.

[0076] See also Figure 4In this embodiment, the support portion 210 includes a connecting plate 211 and a support plate 212 connected at an angle to each other. The two sides of the support plate 212 are in sliding contact with the inner wall of the housing 10. When the support portion 210 is in the first position state, the pusher 40 and the connecting plate 211 are spaced apart, and the side of the connecting plate 211 away from the support plate 212 tilts downwards towards the pusher 40, with the locking portion 220 located inside the housing 10 (see [reference]). Figure 2 When the support part 210 is in the second position, the pusher 40 abuts against the connecting plate 211, and the locking part 220 extends out of the housing 10 (see...). Figure 3 ).

[0077] In the above implementation, the connecting plate 211 is used not only to connect the support plate 212 and the snap-fit ​​part 220, but also to receive the force applied by the pushing member 40, thereby driving the snap-fit ​​part 220 to move. The support plate 212 is used to slide in contact with the inner wall of the housing 10 to support the connecting plate 211, so that the support part 210 can remain stable in both static and dynamic conditions.

[0078] For example, the angle between the connecting plate 211 and the support plate 212 is an acute angle.

[0079] Since there is an acute angle between the connecting plate 211 and the support plate 212, the connecting plate 211 and the support plate 212 are closer together. This helps to reduce the overall volume of the support part 210, so that the support part 210 can have more space to rotate within the housing 10.

[0080] Combination Figure 2 and Figure 3 In this embodiment, the inner wall of the housing 10 has a first support surface 110 and a second support surface 120 that are connected at an angle to each other. The side of the support plate 212 near the connecting plate 211 is in sliding contact with the first support surface 110, and the side of the support plate 212 away from the connecting plate 211 is in sliding contact with the second support surface 120. The support plate 212 is rotatably located between the first support surface 110 and the second support surface 120, so that the support part 210 can switch between a first position state and a second position state.

[0081] In the above implementation, an angle is formed between the first support surface 110 and the second support surface 120, and the support plate 212 is housed within this angle, allowing the support plate 212 sufficient space to rotate. The two sides of the support plate slide in contact with the first support surface 110 and the second support surface 120, respectively. Thus, whether in a static or dynamic state, a stable triangle is formed between the support plate 212, the first support surface 110, and the second support surface 120, effectively ensuring the stability of the support plate 212.

[0082] To further improve the stability of the support plate 212, in this embodiment, the two ends of the support plate 212 protrude from the connecting plate 211, thereby effectively increasing the length of the support plate 212, which in turn increases the contact area between the support plate 212 and the first support surface 110 and the second support surface 120.

[0083] See also Figure 2 and Figure 3 In this embodiment, the driving member 30 is a bolt, which is rotatably connected to the housing 10 and passes through the support 210 and the pusher 40 respectively. The bolt and the pusher 40 are threaded together.

[0084] When the bolt-driven pusher 40 moves relative to the housing 10 toward the support 210, the snap-fit ​​part 220 extends out of the housing 10.

[0085] In the above implementation, the bolt can rotate relative to the housing 10 and the support 210, but there is no threaded engagement between the bolt and the housing 10 and the support 210. Thus, when tightening the bolt, only the pusher 40 rises along the bolt's axial direction until it drives the support 210 from a first position to a second position, i.e., the locking part 220 tilts up and extends out of the housing 10. When tightening the bolt in the opposite direction, the pusher 40 descends along the bolt's axial direction, and the support 210 itself, under the influence of gravity, returns from the second position to the first position, i.e., the locking part 220 falls and retracts into the housing 10.

[0086] Since the support part 210 will rotate, in order to avoid interference between the support part 210 and the bolt during the rotation process, in this embodiment, the support part 210 has an oblong hole 213. The length direction of the oblong hole 213 is on the same plane as the rotation trajectory of the support part 210, and the bolt is inserted into the oblong hole 213.

[0087] Since the length direction of the oblong hole 213 is on the same plane as the rotation trajectory of the support part 210, the oblong hole 213 can provide sufficient movement space for the bolt during the rotation of the support part 210, so that the support part 210 will not collide with the bolt during the movement relative to the bolt.

[0088] For example, the part of the bolt corresponding to the support 210 is a smooth rod, thereby further avoiding interference between the bolt and the support 210.

[0089] Figure 5 This is a structural schematic diagram of the pusher 40, combined with... Figure 5 In this embodiment, the pusher 40 includes a base plate 410 and a pusher plate 420. The pusher plate 420 is connected to the side of the base plate 410 facing the support portion 210, and the base plate 410 is connected to a bolt.

[0090] In the above implementation, the substrate 410 is the main body of the pusher 40, used to engage with the bolt thread. When the bolt is tightened, the substrate 410 can be driven to move along the bolt axial direction. The push plate 420 is connected to the substrate 410. Since the push plate 420 faces the support portion 210, when the push plate 420 moves together with the substrate 410, it can push the support portion 210, causing the support portion 210 to rotate.

[0091] For example, the pusher 40 includes two push plates 420, which are located on both sides of the pusher 40. The two push plates 420 push the support 210 together, so that the support 210 can rotate more stably and avoid the support 210 from tilting when it is pushed.

[0092] In some examples, the pusher 40 also includes a flap 430. The flap 430 is connected to the pusher 420, and the side of the flap 430 facing the substrate 410 slides in contact with the snap-fit ​​portion 220.

[0093] When the bolt-driven pusher 40 moves away from the support 210 relative to the housing 10, the pusher 420 drives the locking part 220 to retract the housing 10.

[0094] During the upward movement of the bolt-driven pusher 40, the pusher 40 moves relative to the housing 10 toward the support 210, and the flap 430 slides along the locking part 220 without applying force to the locking part 220, that is, it does not affect the movement of the hook 20. During the downward movement of the bolt-driven pusher 40, the pusher 40 moves relative to the housing 10 away from the support 210, and the flap 430 applies force to the locking part 220, driving the locking part 220 to move and ensuring that the locking part 220 retracts into the housing 10.

[0095] It should be noted that if the locking mechanism is positioned such that the hook 20 retracts into the housing 10 under its own weight, the flap 430 can be omitted, thus simplifying the manufacturing process. If the locking mechanism is positioned such that the hook 20 cannot retract into the housing under its own weight, then the flap 430 is provided to ensure that the locking part 220 retracts into the housing 10.

[0096] For example, if the pusher 40 includes two push plates 420, then the pusher 40 may correspondingly include two flaps 430, one flap 430 being connected to one push plate 420 and the other flap 430 being connected to the other push plate 420, thereby more securely retracting the drive latch 220 into the housing 10.

[0097] In this embodiment, the substrate 410, the push plate 420 and the flip plate 430 are integrated structural components, which ensures the structural integrity of the pusher 40, improves the structural strength of the pusher 40, and also helps to improve the manufacturing efficiency of the pusher 40.

[0098] In some examples, the pusher 40 is a metal structural component, which effectively ensures the structural strength of the pusher 40. When the base plate 410, push plate 420 and flip plate 430 are integrated structural components, the pusher 40 is a sheet metal component.

[0099] Figure 6 This is a schematic diagram of the structure of the shell 10, combined with... Figure 6 In this embodiment, the housing 10 includes two protective plates 130, which are located on both sides of the hook 20 and the pusher 40, respectively. They not only protect the hook 20 and the pusher 40, but also guide and limit the movement of the hook 20 and the pusher 40, making the movement of the hook 20 and the pusher more stable.

[0100] In this embodiment, the housing 10 includes a top plate 140 and a bottom plate 150, with a hook 20 and a pusher 40 located between the top plate 140 and the bottom plate 150, and bolts rotatably inserted into the top plate 140 and the bottom plate 150 respectively.

[0101] In the above implementation, the top plate 140 and the bottom plate 150 can provide a mounting base for the bolts, so that the bolts can be securely installed in the housing 10.

[0102] For example, the housing 10 is an integral structural component, which ensures the structural integrity of the housing 10, not only improving the structural strength of the housing 10, but also helping to improve the manufacturing efficiency of the housing 10.

[0103] In some examples, the housing 10 is a metal structural component, which effectively ensures the structural strength of the housing 10. When the housing 10 is a one-piece structural component, the housing 10 is a sheet metal part.

[0104] Figure 7 This is a schematic diagram of the structure of a socket provided in an embodiment of the present disclosure, combined with... Figure 7 In this embodiment, the socket includes a socket body 100 and Figures 1-6 The locking mechanism 200 shown is located on opposite sides of the socket body 100.

[0105] Because the socket includes Figures 1-6 The locking mechanism 200 shown means that the socket has... Figures 1-6 All the beneficial effects of the locking mechanism 200 shown will not be elaborated here.

[0106] See also Figure 7In this embodiment, the outer wall of the socket body 100 has a socket 1100, and the locking mechanism 200 is inserted into the socket 1100.

[0107] In the above implementation, the number of sockets 1100 is the same as the number of locking mechanisms 200, thus ensuring that there are enough sockets 1100 for the locking mechanisms 200. The sockets 1100 can securely accommodate the locking mechanisms 200, thereby enabling the socket to be fixedly installed on the carrier.

[0108] For example, the carrier can be a desktop, wall, etc., and its material is sufficient to allow the hook 20 to be embedded, thereby achieving a stable installation of the socket.

[0109] This disclosure provides a table, which includes a tabletop and a... Figure 7 The socket shown is fitted into a hole in the desktop, with the hook 20 abutting against the wall of the hole.

[0110] Because the table includes Figure 7 The table has the socket shown, so it has... Figure 7 The full benefits of the socket shown will not be elaborated here.

[0111] For example, the table may be an office desk, a hotel table, a conference table, etc., and this disclosure does not limit it.
