Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical equipment technology, and more specifically, to a track socket adapter. Background Technology
[0002] The track socket includes an adapter and a track. The track has conductive rails extending along its length, and these rails are energized. The adapter has a conductive swing arm that can be extended or retracted. The adapter can be inserted into the track; by extending the conductive swing arm, it contacts the conductive rail, thus energizing the adapter. Because the adapter can be inserted into any position on the track, it can power appliances in multiple locations, thereby improving power supply flexibility.
[0003] For example, Chinese Patent Publication No. CN116845649A, published on October 3, 2023, entitled "Adapter and Track Socket," describes an invention where the transmission component and driven rocker are located between the inner wall of the housing and the socket assembly. This arrangement effectively places the transmission component and driven rocker near the edge of the housing, leaving the middle of the housing for the socket assembly. This allows the socket assembly to be located in the center of the housing. Consequently, the transmission component, driven rocker, and socket assembly can be situated in the same layer, eliminating the need to separate them into different layers due to space constraints. This effectively reduces the thickness of the adapter, making it thinner. However, the complex structure of the transmission component and driven rocker increases the cost of manufacturing and assembling the parts, thus increasing production costs. Utility Model Content
[0004] This invention overcomes the problem in the prior art where, in order to make the overall structure thinner, the transmission component and driven swing member are placed on the edge of the housing, leaving the middle position empty for the installation of the socket assembly. However, due to the complex structure of the transmission component and driven swing member, the manufacturing and assembly costs of the parts are increased, thus increasing the production cost. This invention provides a track socket adapter that simplifies the overall structure compared with the prior art, thereby reducing the production cost of parts manufacturing and assembly.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a track socket adapter, comprising:
[0006] The bottom shell has a rotating ring on its bottom surface;
[0007] A support plate adapted to the rotating ring, with a swing arm at the bottom of the support plate;
[0008] A stationary contact piece is embedded in the support plate; one end of the stationary contact piece extends out of the swing arm, and the other end is provided with a swing groove located in the bottom shell;
[0009] A movable contact piece is inserted into a swing groove, and a swing block is provided at one end of the movable contact piece;
[0010] The rotating ring is equipped with a trigger block that cooperates with the swing block.
[0011] In this application, when the rotating ring is rotated clockwise, the moving contact engages with the trigger terminal, energizing the socket and the stationary contact. When the rotating ring is rotated counterclockwise, the moving contact separates from the trigger terminal, de-energizing the socket and the stationary contact. Compared with the prior art, the socket structure in this application can be mounted inside the base shell, and while maintaining a slimmer overall structure, it uses a combination of a trigger block, a swing block, a moving contact, and a stationary contact to control the energization and de-energization of the socket. The structure is simpler and more convenient to use. It can reduce the production costs of parts manufacturing and assembly.
[0012] Preferably, a sleeve is provided on the support plate, and a trigger terminal is provided on the sleeve. The trigger terminal is located at the end of the moving contact away from the swing block.
[0013] When the rotating ring rotates, it drives the trigger block to rotate. The rotation of the trigger block, in turn, pushes the oscillating block to rotate, causing the moving contact to rotate around the oscillating groove. This causes the trigger contact to engage or disengage from the trigger terminal. When the moving contact engages with the trigger terminal, the socket contacts the stationary contact, energizing the socket. Conversely, when the moving contact disengages from the trigger terminal, the socket separates from the stationary contact, de-energizing the socket.
[0014] Preferably, the swing block is rotatably disposed inside the bottom shell, and a swing spring abuts between the moving contact plate and the swing block.
[0015] The swing spring can push the moving contact to maintain a state of being in contact with or separated from the trigger terminal.
[0016] Preferably, the side of the swing block away from the moving contact piece is provided with a concave groove, and when the rotating ring is rotated, the trigger block abuts against the side wall of the concave groove alone.
[0017] When the ring rotates, the trigger block on the rotating ring can slide on both sides of the concave groove, which can better drive the trigger block to rotate.
[0018] Preferably, the swing block has convex shafts on both sides, a first hole on the support plate, and a second hole corresponding to the first hole on the bottom of the bottom shell; the convex shafts on both sides of the swing block are rotatably connected to the first hole and the second hole respectively.
[0019] The convex shafts on both sides of the swing block are rotatably connected to the first hole and the second hole respectively, and the swing block can rotate around the convex shafts.
[0020] Preferably, an insertion panel is provided on the side of the rotating ring away from the bottom shell; several support columns are provided on the bottom shell, and a fixing column that cooperates with the support columns is provided on the insertion panel.
[0021] The support column and the fixed column are fixedly connected by bolts, thus securing the insert panel to the bottom shell. A rotating ring is fixed between the bottom shell and the insert panel, allowing the rotating ring to rotate relative to both the bottom shell and the insert panel.
[0022] Preferably, the edge of the support plate is provided with a side groove that cooperates with the support column, and the side groove cooperates with the support column to restrict the rotation of the support plate relative to the bottom shell.
[0023] The side groove and the support column work together to form a limiting structure, restricting the rotation of the support plate relative to the bottom shell. Therefore, when the rotating ring rotates, it can rotate simultaneously relative to both the support plate and the bottom shell.
[0024] Preferably, a connecting column is provided at the center of the support plate, and a swing arm is provided at the end of the connecting column; a grounding contact is provided inside the connecting column.
[0025] The two ends of the grounding contact extend from the end of the connecting post and the end of the support plate, respectively, to achieve the grounding function.
[0026] Preferably, a side wall hole is provided on the side wall of the bottom shell, and a locking key is slidably provided in the side wall hole. The locking key maintains the tendency to move towards the side wall hole under the action of the locking spring. A locking block is provided on the rotating ring, and a locking groove is provided on the locking key. After the locking key is pressed, the locking groove and the locking block are separated, and the rotating ring and the bottom shell can rotate relative to each other.
[0027] In this embodiment, the cooperation between the locking key and the locking block can control the rotation of the rotating ring.
[0028] Preferably, the bottom of the rotating ring is fixedly connected to an insert plate, and an avoidance groove is provided at the center of the insert plate. The avoidance groove divides the insert plate into two single plates, and storage grooves communicating with the avoidance groove are provided on different sides of the two single plates. The storage grooves are perpendicular to the avoidance grooves.
[0029] By rotating the rotating ring, the ring can rotate relative to the support plate, thereby allowing the swing arm to extend out of the storage slot and retract into the storage slot.
[0030] Compared with the prior art, the beneficial effects of this utility model are as follows: In this application, when the rotating ring is rotated clockwise, the moving contact and the trigger terminal are engaged, energizing the socket and the stationary contact. When the rotating ring is rotated counterclockwise, the moving contact and the trigger terminal are disengaged, de-energizing the socket and the stationary contact. Compared with the prior art, the socket structure in this application can be mounted in the bottom shell, and while ensuring a thinner overall structure, it uses a combination of trigger block, swing block, moving contact, and stationary contact to control the energization and de-energization of the socket. The structure is simpler and more convenient to use. It can reduce the production costs of parts manufacturing and assembly. Attached Figure Description

[0051] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:
[0052] Example 1: Refer to Figures 1 to 10 As shown, a track socket adapter includes:
[0053] The bottom shell 1 has a rotating ring 2 on its bottom surface;
[0054] A support plate 3 adapted to the rotating ring 2, and a swing arm 32 is provided at the bottom of the support plate 3;
[0055] A stationary contact piece 4 is embedded in the support plate 3; one end of the stationary contact piece 4 extends out of the swing arm 32, and the other end is provided with a swing groove 41 located in the bottom shell 1;
[0056] A movable contact 5 is inserted into the swing groove 41, and a swing block 6 is provided at one end of the movable contact 5;
[0057] The rotating ring 7 is equipped with a trigger block 71 that cooperates with the swing block 6.
[0058] Specifically, such as Figure 2As shown, a third hole 11 is provided at the center of the bottom shell 1, and the rotating ring 2 is rotatably disposed within the third hole 11, meaning that the rotating ring 2 can rotate freely within the third hole 11. The support plate 3 is rotatably disposed within the rotating ring 2, and the support plate 3 and the bottom shell 1 are limited in the circumferential direction by a limiting structure, so that the support plate 3 and the bottom shell 1 cannot rotate relative to each other. Therefore, when the rotating ring 2 rotates, the rotating ring 2 rotates relative to both the support plate 3 and the bottom shell 1 simultaneously.
[0059] like Figure 7 and Figure 8 As shown, an insert plate 21 is fixedly connected to the bottom of the rotating ring 2. A clearance groove 22 is provided at the center of the insert plate 21, dividing the insert plate 21 into two single plates. Storage grooves 23 communicating with the clearance groove 22 are provided on different sides of the two single plates. The storage grooves 23 are perpendicular to the clearance groove 22. That is to say, storage grooves 23 are provided on both single plates, for a total of two storage grooves 23. The two storage grooves 23 are not on the same side, but are located on both sides of the insert plate 21.
[0060] like Figure 4 and Figure 5 As shown, a connecting post 31 is provided at the center of the support plate 3. The connecting post 31 is located on the bottom surface of the support plate 3 and is fitted into the clearance groove 22. A swing arm 32 is located at the end of the connecting post 31. Two swing arms 32 are provided, symmetrically positioned at the ends of the connecting post 31. A stationary contact piece 4 is embedded in each of the two swing arms 32, extending beyond the end of the swing arm 32 for contact with the conductive slide rail of the track socket. The two swing arms 32 are also adapted to the storage groove 23. By rotating the rotating ring 2, the rotating ring 2 can rotate relative to the support plate 3, thereby allowing the swing arms 32 to extend out of the storage groove 23 and retract into the storage groove 23.
[0061] A grounding contact 311 is provided at the center of the connecting post 31. The two ends of the grounding contact 311 extend out of the end of the connecting post 31 and the end of the support plate 3, respectively. The end of the grounding contact 311 extending out of the connecting post 31 contacts the conductive rail, and the end of the grounding contact 311 extending out of the end face of the support plate 3 is connected to the grounding socket 83, thereby realizing the grounding function.
[0062] Of the two stationary contact pieces 4 on the swing arms 32, one of the stationary contact pieces 4 is provided with a swing groove 41, which is located inside the bottom shell 1. A movable contact piece 5 is inserted into the swing groove 41, and the movable contact piece 5 can rotate around the swing groove 41 while maintaining an electrical connection with the swing groove 41.
[0063] like Figure 6As shown, a socket 8 is provided on the support plate 3, namely a positive socket 81, a negative socket 82, and a grounding socket 83. In this application, the positive socket 81, the negative socket 82, and the grounding socket 83 are all made of copper, as are the grounding contact 311, the stationary contact 4, and the moving contact 5. The grounding socket 83 is connected to the grounding contact 311. A trigger terminal 84 is provided on either the positive socket 81 or the negative socket 82, and the trigger terminal 84 is located at the end of the moving contact 5 away from the swing block 6.
[0064] When the rotating ring 7 rotates, it drives the trigger block 71 to rotate. During this rotation, the trigger block 71 pushes the swing block 6 to rotate, causing the moving contact 5 to rotate around the swing groove 41, thus causing the trigger piece 84 to engage or disengage from the trigger terminal 84. When the moving contact 5 engages with the trigger terminal 84, the socket 8 contacts the stationary contact 4, energizing the socket 8. When the moving contact 5 disengages from the trigger terminal 84, the socket 8 disengages from the stationary contact 4, de-energizing the socket 8.
[0065] Specifically, in this application, when the rotating ring 7 is rotated clockwise, the moving contact 5 engages with the trigger terminal 84, energizing the socket 8 and the stationary contact 4. When the rotating ring 7 is rotated counterclockwise, the moving contact 5 separates from the trigger terminal 84, de-energizing the socket 8 and the stationary contact 4. Compared with the prior art, the socket 8 structure in this application can be directly installed inside the bottom shell 1. While maintaining a thinner overall structure, the energizing and de-energizing of the socket 8 is controlled by the coordinated use of the trigger block 71, the swing block 6, the moving contact 5, and the stationary contact 4. The structure is simpler and more convenient to use. This reduces the production costs of parts manufacturing and assembly.
[0066] In one embodiment, the swing block 6 has protruding shafts 61 on both sides, a first hole 341 on the support plate 3, and a second hole 12 corresponding to the first hole 341 on the bottom of the bottom shell 1. The protruding shafts 61 on both sides of the swing block 6 are rotatably connected to the first hole 341 and the second hole 12, respectively. Specifically, a limiting plate 34 is provided on the support plate 3, and a space is left between the limiting plate 34 and the bottom of the bottom shell 1. The swing block 6 is disposed in the space between the limiting plate 34 and the bottom shell 1. The first hole 341 is provided on the limiting plate 34, allowing the swing block 6 to rotate around the protruding shafts 61.
[0067] A swing spring 62 abuts between the movable contact 5 and the swing block 6. In order for the swing spring 62 to be firmly abutted between the movable contact 5 and the swing block 6, a protrusion 51 is provided on the movable contact 5, and an abutment hole 63 is provided on the swing block 6. The two ends of the swing spring 62 abut against the abutment hole 63 and the protrusion 51, respectively.
[0068] When the rotating ring 7 rotates, the trigger block 71 on the rotating ring 7 acts on the swing block 6, causing the swing block 6 to rotate around the convex shaft 61. During the rotation of the swing block 6, the moving contact 5 can swing around the swing groove 41 through the abutting action of the swing spring 62, thereby realizing the contact 5 and the trigger terminal 84 to be engaged and disengaged. Through the action of the swing spring 62, the moving contact 5 can be pushed to maintain the state of being engaged and disengaged from the trigger terminal 84.
[0069] A concave groove 64 is provided on the side of the swing block 6 away from the moving contact piece 5. When the rotating ring 7 is rotated, the trigger block 71 abuts against the side wall of the concave groove 64. The concave groove 64 has a symmetrical structure and can be an arc-shaped or V-shaped groove. In this application, the concave groove 64 is a V-shaped structure. The axis of the abutment hole 63 is perpendicular to the axis of symmetry of the concave groove 64. When the rotating ring 7 rotates, the trigger block 71 on the rotating ring 7 can slide on both sides of the concave groove 64, thereby better pushing the trigger block 71 to rotate.
[0070] In one embodiment, an insertion panel 9 is provided on the side of the rotating ring 7 away from the bottom shell 1; a plurality of support columns 13 are provided on the bottom shell 1, and a fixing column 91 that cooperates with the support columns 13 is provided on the insertion panel 9. The support columns 13 and the fixing column 91 are fixedly connected by bolts, so that the insertion panel 9 and the bottom shell 1 are fixed together. The rotating ring 7 is fixed between the bottom shell 1 and the insertion panel 9, and the rotating ring 7 can rotate relative to the bottom shell 1 and the insertion panel 9. The insertion panel 9 is provided with an insertion hole 92 that cooperates with the insertion sleeve 8.
[0071] The edge of the support plate 3 is provided with a side groove 33 that cooperates with the support column 13. The side groove 33 and the support column 13 cooperate to form a limiting structure, restricting the rotation of the support plate 3 relative to the bottom shell 1. Thus, when the rotating ring 2 rotates, the rotating ring 2 can rotate simultaneously relative to the support plate 3 and the bottom shell 1.
[0072] The working principle of this application is as follows: Insert the insert plate 21 into the track, and then rotate the bottom shell 1. The insert plate 21 is fixed under the action of the track. The bottom shell 1 drives the support plate 3, the insert sleeve 8, the rotating ring 7, and the insert plate 9 to rotate relative to the rotating ring 7 at the same time, so that the connecting column 31 rotates relative to the clearance groove 22, and the swing arm 32 swings out from the storage groove 23 and contacts the conductive slide rail.
[0073] Then, rotating the rotating ring 7 clockwise causes the trigger block 71 to rotate. During this rotation, the trigger block 71 pushes the swing block 6 to rotate, causing the moving contact 5 to rotate around the swing groove 41, thus bringing the trigger piece 84 into contact with the trigger terminal 84. When the moving contact 5 is in contact with the trigger terminal 84, the socket 8 and the stationary contact 4 are energized, thus powering the socket 8. Similarly, when rotating the rotating ring 7 counterclockwise, the moving contact 5 separates from the trigger terminal 84, and the socket 8 separates from the stationary contact 4, thus de-energizing the socket 8.
[0074] Compared with existing technologies, the socket 8 structure in this application can be directly installed inside the bottom shell 1. While ensuring a thinner overall structure, it uses a combination of trigger block 71, swing block 6, moving contact 5, and stationary contact 4 to control the power supply and de-energization of the socket 8. The structure is simpler and more convenient to use. It can reduce the production costs of parts manufacturing and assembly.
[0075] Example 2: This example is similar in structure to Example 1, except that a side wall hole 14 is provided on the side wall of the bottom shell 1, and a locking key 10 is slidably provided in the side wall hole 14. The locking key 10 maintains a tendency to move towards the side wall hole 14 under the action of the locking spring 101. A locking block 24 is provided on the rotating ring 2, and a locking groove 102 is provided on the locking key 10. After the locking key 10 is pressed and the locking groove 102 separates from the locking block 24, the rotating ring 2 and the bottom shell 1 can rotate relative to each other.
[0076] An inclined surface 241 is provided on the locking block 24, and a guide plate 103 is provided on the locking key 10.
[0077] In this embodiment, the locking key 10 and the locking block 24 are configured to cooperate to control the rotation of the rotating ring 2. Specifically, after the insert plate 21 is inserted into the track, when the swing arm 32 needs to be swung out of the storage groove 23 to contact the conductive slide rail, the guide plate 103 will move along the inclined surface 241 when the housing is rotated. The inclined surface 241 pushes the guide plate 103 to move, thereby pushing the locking key 10 to move. When the swing arm 32 is swung out of the storage groove 23 and contacts the conductive slide rail, the locking block 24 cooperates with the locking groove 102. The locking groove 102 locks the locking block 24, and the rotating ring 2 cannot rotate at this time, remaining in an energized state.
[0078] When it is necessary to pull the insert plate 21 out of the track, the locking key 10 needs to be pressed at the same time. The locking key 10 moves into the housing against the force of the locking spring 101. After the locking groove 102 separates from the locking block 24, the rotating ring 2 and the bottom shell 1 can rotate relative to each other. At this time, the bottom shell 1 drives the support plate 3, the insert sleeve 8, the rotating ring 7, and the insert plate 9 to rotate relative to the rotating ring 7 at the same time, so that the connecting column 31 rotates relative to the clearance groove 22, and the swing arm 32 swings back into the storage groove 23 and separates from the conductive slide rail.
[0079] The above structure can fix the rotating ring 2 and keep the swing arm 32 energized with the conductive slide rail.
[0080] It should be noted that the support plate 3 is also provided with an opening groove 35, which can avoid the locking key 10. Specifically, when the locking key 10 is pressed inward, the locking key 10 will move into the opening groove 35 to avoid interference with the support plate 3 when the locking key 10 is pressed.
[0081] In one embodiment, two locking blocks 24 are provided, the line connecting the two locking blocks 24 is perpendicular to the insert plate 21, and the two locking blocks 24 are centrally symmetrically distributed with respect to the center of the rotating ring 2. Furthermore, the overall structure of the rotating ring 2 is also centrally symmetrically distributed only with respect to the center of the rotating ring 2. This distribution facilitates the assembly of the rotating ring 2, eliminating the need to consider the installation direction during installation; simply inserting the rotating ring 2 into the third hole 11 is sufficient for installation, thus simplifying the assembly of the overall structure.
