Description

Technical Field

[0001] The present application relates to the technical field of track sockets, and in particular to a track socket with a dust cleaning function. Background Art

[0002] Multiple sockets are usually installed on the walls of modern decorated interiors for power supply. However, the positions of the sockets designed are often inconsistent with the actual positions required during subsequent living. Therefore, track sockets have emerged. Common track sockets include a track and several socket modules. The track is fixedly installed on the wall, and three conductive copper bars are provided in the track. The three conductive copper bars are respectively connected to the live wire, neutral wire, and ground wire of the power supply. One end of the socket module is slidably inserted into the track, and three metal contacts are provided at the end of the socket module located inside the track for tightly abutting against the three conductive copper bars to conduct electricity.

[0003] During daily use, if the length of the wire of the electrical plug is insufficient, the socket module can be slid towards the electrical appliance until the plug of the electrical appliance can be inserted into the socket module. Since the conductive copper bars and the power supply wires are hidden inside the track, the track socket has a relatively neat and beautiful appearance. At the same time, the internal wires are protected by the track and are not easily damaged to cause electric leakage, which is relatively safe.

[0004] After long-term use of the track socket, poor contact may occur. Most of the reasons for the poor contact of the track socket are due to the accumulation of dust inside the track after long-term use. However, a small part is also due to the aging of the internal wires of the socket module or the track, resulting in poor contact.

[0005] If the poor contact is caused by dust accumulation, it can be used normally after only cleaning the dust. If the poor contact is caused by wire aging, the entire track socket needs to be replaced.

[0006] However, due to the strong integrity of the track socket, it is difficult to observe the internal situation and clean the dust inside the track socket without disassembling the track socket. Maintenance usually needs to be carried out after disassembling the track. Therefore, it may be that the poor contact is actually caused by wire aging, but during maintenance, it is necessary to disassemble the track and clean the dust before the cause can be found through the elimination method, which is time-consuming and laborious. Summary of the Invention

[0007] In order to solve the problem that it is relatively troublesome to clean and inspect the internal dust of traditional track sockets, the present application provides a track socket with a dust cleaning function.

[0008] The track socket with a dust cleaning function provided by the present application adopts the following technical solutions: A track socket with a dust cleaning function, comprising: A track, which is used to be installed on a wall and connected to a power supply for power supply; A protective shell that covers the track and has a long hole corresponding to the track; A socket module, one end of which passes through the long hole and is slidably installed on the track, serving as an intermediary for electrical connection between an electrical plug and the track; A bracket, which is slidably installed on the track; A cleaning block, which is installed on the bracket and is used to frictionally clean the conductive copper strip of the track in cooperation with the sliding of the bracket.

[0009] Through the above technical solution, when it is found that the socket module has a poor contact phenomenon, first check whether the socket module is damaged. When it is found that the socket module is normal, remove the plastic plugging block at one end of the protective shell, and then push the bracket to slide from one end of the track to the other end. The conductive copper strip in the track is frictionally cleaned by the cleaning block on the bracket, and then the dust scraped off the conductive copper strip is pushed out from the opened end of the track. After the bracket is reset, the socket module is installed on the track again. If the socket module returns to normal at this time, that is, the reason for the poor contact is the dust accumulation on the conductive copper strip. If the socket module still has a poor contact at this time, the reason for the poor contact is that the internal components or circuits of the track are aging, and the track needs to be replaced.

[0010] Optionally, the bracket is provided with a detection lamp. The bracket is provided with a plurality of metal contacts, and the metal contacts are electrically connected to the power supply end of the detection lamp. The metal contacts are used to contact the conductive copper strip in the track during the sliding process of the bracket to supply power to the detection lamp. Taking the sliding direction of the bracket during cleaning as the positive direction, the cleaning block is located in front of the metal contacts.

[0011] Optionally, the detection lamp uses a color-changing lamp, which shows different colors according to different voltages provided by the metal contacts.

[0012] Through the above technical solution, through the color change of the detection lamp, if the color of the detection lamp is always the color at the standard voltage, it means that the poor contact inside the track is only caused by dust accumulation. If the color of the detection lamp changes, it means that there is an aging phenomenon in the internal components or circuits of the track, and it needs to be disassembled and repaired or directly replaced.

[0013] Optionally, the conductive copper strip connected to the live wire and the conductive copper strip connected to the neutral wire in the track are located on both sides of the track, and the conductive copper strip connected to the ground wire in the track is located on the side where the track is connected to the wall; The bracket is rotatably installed with a mounting rod, wherein two of the metal contacts are arranged at both ends of the mounting rod. A wire is arranged inside the mounting rod. The metal contacts are electrically connected to the detection lamp through the wire. The bracket is provided with a driving mechanism for driving the mounting rod to rotate. The mounting rod can rotate until the metal contacts at both ends thereof respectively abut against the conductive copper bar connected to the live wire and the conductive copper bar connected to the neutral wire, and the remaining metal contacts normally abut against the conductive copper bar connected to the ground wire.

[0014] Optionally, the driving mechanism includes a driving shaft rotatably installed on the bracket. One end of the driving shaft sequentially slides through the track and the long hole and is located outside. A driven gear is coaxially arranged on the mounting rod with its rotation axis. The driven gear is in transmission connection with the driving shaft.

[0015] Optionally, a support rod is slidably installed in the housing. The cleaning block is arranged on the support rod. The driving shaft is coaxially provided with a first driving gear. The support rod for installing the cleaning block for cleaning the live wire or the neutral wire is provided with a rack meshing with the first driving gear. The two support rods are respectively located on both sides of the first driving gear. The support rod for installing the cleaning block for cleaning the ground wire coaxially passes through the driving gear and is in threaded cooperation with the driving gear.

[0016] Optionally, the driving shaft includes a first mounting shaft and a second mounting shaft. The first mounting shaft is rotatably installed in the housing. The second mounting shaft is coaxially rotatably installed on the first mounting shaft. The first driving gear is coaxially arranged on the first mounting shaft. The second mounting shaft is in transmission connection with the driven gear. The first mounting shaft is coaxially provided with a transmission shaft. The transmission shaft coaxially passes through the second mounting shaft. The handle is arranged on the transmission shaft. The second mounting shaft is provided with a fixing mechanism for fixing with the first mounting shaft.

[0017] Optionally, the fixing mechanism includes a friction ring arranged at one end of the second mounting shaft. The handle is slidably installed on the transmission shaft. The handle is circumferentially fixed to the transmission shaft. The handle is provided with a receiving cavity. The receiving cavity is in interference fit with the friction ring. The inner wall of the receiving cavity is covered with an anti-slip layer. The transmission shaft is provided with a pressing member for pushing the handle to abut against the friction ring.

[0018] Optionally, a slider is slidably mounted on the handle, a spring is provided inside the handle, and a chute is provided on the protective shell. When the handle rotates until the metal contact abuts against the conductive copper bar, the slider is slidably mounted in the chute under the push of the spring. A first push block is slidably mounted on the handle, and a second push block is provided on the slider. The first push block and the second push block are both provided with inclined surfaces, and the inclined surfaces of the first push block and the second push block are mutually attached. When the slider slides into the chute under the push of the spring, the second push block pushes the first push block to slide and protrude in a direction away from the handle through the inclined surface.

[0019] Optionally, the pressing member includes a fixing sleeve threadedly mounted on the transmission shaft, and the fixing sleeve is rotatably connected to the handle coaxially.

[0020] In summary, when it is found that the socket module has a poor contact phenomenon, first check whether the socket module is damaged. When it is found that the socket module is normal, remove the plastic plugging block at one end of the track, then push the bracket to slide from one end of the track to the other end, and clean the conductive copper bar in the track by rubbing with the cleaning block on the bracket. Then, push out the dust scraped from the conductive copper bar from the opened end of the track. After resetting the bracket, install the socket module on the track again. If the socket module returns to normal at this time, that is, the reason for the poor contact is the dust accumulation on the conductive copper bar. If the socket module is still poorly contacted at this time, the reason for the poor contact is the aging of the internal components or circuits of the track, and the track needs to be replaced. At the same time, through the color change of the detection lamp, if the color of the detection lamp is always the color at the standard voltage, it means that the poor contact inside the track is only caused by dust accumulation. If the color of the detection lamp changes, it means that there is an aging phenomenon in the internal components or circuits of the track, and it needs to be disassembled and repaired or directly replaced, and the detection is more convenient and intuitive.

Detailed implementation manners

[0030] The following will further elaborate on this application in conjunction with the attached Figure 1-7 drawings for a more detailed description.

[0031] An embodiment of this application discloses a track 1 socket with a dust cleaning function. Referring to Figure 1 and Figure 2 , it includes a track 1, a protective shell 2 installed on the track 1, several socket modules 11, and a bracket 3.

[0032] Referring to Figure 3 and Figure 4 , the track 1 is made of aluminum profile and is fixedly installed on the wall horizontally. Conductive copper strips are fixedly installed on both the upper and lower sides of the inner cavity of the track 1, and these two conductive copper strips are respectively connected to the live wire and neutral wire of the power supply through wires.

[0033] Referring to Figure 3 and Figure 4 , a conductive copper strip is fixedly installed on the inner wall of the side of the track 1 that fits the wall, and this conductive copper strip is located between the above-mentioned conductive copper strips in the front. This conductive copper strip is connected to the ground wire of the power supply through a wire.

[0034] Referring to Figure 1, the protective shell 2 covers the track 1. A long hole 21 is formed through the protective shell 2 along the length direction of the track 1. The power supply end of the socket module 11 slides through the long hole 21 and then slides into the track 1, and the socket module 11 is powered by the connection between the power supply contacts on the socket module 11 and the conductive copper bar.

[0035] Refer to Figure 4 and Figure 5 , the bracket 3 is slidably installed on the track 1. The bracket 3 is box-shaped. A detection lamp 31 is fixedly installed on the bracket 3. A mounting rod 32 is rotatably installed in the bracket 3. Metal contacts 5 are provided at both ends of the mounting rod 32. The metal contacts 5 are electrically connected to the detection lamp 31 through wires. The mounting rod 32 can be rotated to press the two metal contacts 5 against the two conductive copper bars on the upper and lower sides of the track 1 respectively, so as to supply power to the detection lamp 31.

[0036] Refer to Figure 4 and Figure 5 , a metal contact 5 is also fixedly installed on the bracket 3. The metal contact 5 is electrically connected to the grounding end of the detection lamp 31, and the metal contact 5 presses against the conductive copper bar connected to the grounding wire.

[0037] Refer to Figure 5 , Figure 6 and Figure 7 , the bracket 3 is provided with a driving mechanism 7 for driving the mounting rod 32 to rotate. The driving mechanism 7 includes a driving shaft 71 rotatably installed on the bracket 3. A second driving gear 76 is coaxially and fixedly installed on the driving shaft 71. The second driving gear 76 is an incomplete gear to save the internal space of the bracket 3. A driven gear 72 is coaxially and fixedly installed on the mounting rod 32 with its rotation axis. The driven gear 72 meshes with the second driving gear 76, and the mounting rod 32 is driven to rotate by rotating the driving shaft 71.

[0038] Refer to Figure 5 , Figure 6 and Figure 7 , the bracket 3 is provided with three cleaning blocks 33 and three support rods 8. The support rods 8 are slidably installed on the bracket 3, and the cleaning blocks 33 are fixedly installed on the support rods 8. One rack 81 is integrally provided along the length direction of two of the support rods 8. A first driving gear 73 is coaxially and fixedly installed on the driving shaft 71. The two support rods 8 are respectively located on both sides of the first driving gear 73, and at the same time, both racks 81 mesh with one end driving gear. The two support rods 8 are driven to slide relatively or away from each other by rotating the driving shaft 71.

[0039] Refer to Figure 5 , Figure 6 and Figure 7, one end of the third support rod 8 penetrates into the end face of the drive shaft 71 and is in threaded cooperation with the drive shaft 71. When the drive shaft 71 rotates, it will push the third support rod 8 to extend or retract from the bracket 3.

[0040] Refer to Figure 5 , Figure 6 and Figure 7 , when the drive shaft 71 rotates until the metal contact 5 abuts against the conductive copper bar, the support rod 8 pushes the cleaning block 33 to respectively abut against the three conductive copper bars, and then pushes the bracket 3 to slide to scrape and clean the conductive copper bar.

[0041] Refer to Figure 5 , Figure 6 and Figure 7 , one end of the drive shaft 71 passes through the long hole 21 and is located outside. A handle 4 is coaxially installed at the end of the drive shaft 71. A slider 41 is slidably installed inside the handle 4. A chute 22 is opened along the length direction of the track 1 on the protective shell 2. A spring 42 is provided inside the handle 4. When the handle 4 rotates until the metal contact 5 abuts against the conductive copper bar, the slider 41 slides and is installed in the chute 22 under the push of the spring 42.

[0042] Through the cooperation between the slider 41 and the chute 22, the rotation of the drive shaft 71 is limited, so that both the cleaning block 33 and the metal contact 5 can stably abut against the conductive copper bar.

[0043] The cleaning block 33 is driven by the sliding of the bracket 3 to scrape on the conductive copper bar to clean the conductive copper bar. Taking the sliding direction of the bracket 3 during cleaning as the positive direction, the cleaning block 33 is located in front of the metal contact 5. The detection lamp 31 uses a color-changing lamp and presents different colors according to different voltages. When the cleaning block 33 finishes cleaning, if the detection lamp 31 presents the color of the normal voltage, it means that the poor contact is caused by dust accumulation. If the detection lamp 31 presents the color of the low-voltage state, it means that the poor contact is due to the aging of the components and circuits inside the track 1.

[0044] Refer to Figure 5 , Figure 6 and Figure 7 , a first push block 91 is slidably installed on the handle 4. The slider 41 is integrally provided with a second push block 92. The first push block 91 and the second push block 92 are both provided with inclined surfaces 93. The inclined surfaces 93 of the first push block 91 and the second push block 92 are mutually attached. When the slider 41 slides into the chute 22 under the push of the spring 42, the second push block 92 pushes the first push block 91 to slide and protrude in the direction away from the handle 4 through the inclined surface 93.

[0045] The slider 41 can be pushed back by the second pushing block 92, and the reset of the handle 4 is relatively convenient. At the same time, when the rotation and movement of the handle 4 are both reset, the second pushing block 92 is released, and the slider 41 is pushed by the spring 42 to abut against the outer side wall of the protective shell 2 to limit the sliding of the bracket 3.

[0046] Referring to Figure 5 , Figure 6 and Figure 7 , the drive shaft 71 includes a first mounting shaft 711 and a second mounting shaft 712. The first mounting shaft 711 is rotatably mounted in the housing. The first mounting shaft 711 is coaxially and integrally provided with a transmission shaft 713. One end of the transmission shaft 713 passes through the long hole 21 and is located outside. The second mounting shaft 712 is coaxially rotatably sleeved on the transmission shaft 713. The first driving gear 73 is coaxially fixed on the first mounting shaft 711, and the second driving gear 76 is coaxially fixedly mounted on the second mounting shaft 712.

[0047] Referring to Figure 5 , Figure 6 and Figure 7 , the second mounting shaft 712 is provided with a fixing mechanism 6 for forming a fixation with the first mounting shaft 711. The fixing mechanism 6 includes a friction ring 61 coaxially and fixedly mounted at one end of the second mounting shaft 712 away from the first mounting shaft 711. The friction ring 61 is frustum-shaped. The handle 4 is slidably mounted at one end of the transmission shaft 713 and is circumferentially fixed to the transmission shaft 713 through a key connection. One end of the handle 4 facing the second mounting shaft 712 is coaxially provided with a receiving cavity 43 for fitting with the friction ring 61. The inner wall of the receiving cavity 43 is covered with an anti-slip layer. When the handle 4 slides to the friction ring 61 being embedded in the receiving cavity 43, the handle 4 forms a circumferential fixation between the first mounting shaft 711 and the second mounting shaft 712 through friction.

[0048] Referring to Figure 5 , Figure 6 and Figure 7 , the transmission shaft 713 is further provided with a pressing member 62. The pressing member 62 includes a fixing sleeve 621 threadedly mounted on the transmission shaft 713. One end of the fixing sleeve 621 is coaxially rotatably connected to the handle 4. When the fixing sleeve 621 is tightened, the fixing sleeve 621 pushes the handle 4 to slide to the friction ring 61 being embedded in the receiving cavity 43, so that the first mounting shaft 711 and the second mounting shaft 712 are both circumferentially fixed and axially fixed. After loosening the fixing sleeve 621, the fixing sleeve 621 drives the handle 4 to disengage from the friction ring 61, so that the second mounting shaft 712 and the first mounting shaft 711 can rotate relative to each other.

[0049] After long-term use, the cleaning block 33 will wear out, so that when the first mounting shaft 711 drives the mounting rod 32 to rotate until the metal contact 5 abuts against the conductive copper bar, the pressure between the cleaning block 33 and the conductive copper bar decreases, resulting in a decline in the cleaning effect of the cleaning block 33 on the conductive copper bar. At this time, loosen the fixing sleeve 621, and the slider 41 still remains in the chute 22. Then rotate the second mounting shaft 712 until the cleaning block 33 abuts against the conductive copper bar again, and then tighten the fixing sleeve 621 to re-fix the second mounting shaft 712 and the first mounting shaft 711. After adjustment, the cleaning block 33 restores the cleaning effect on the conductive copper bar.

[0050] Refer to Figure 5 , Figure 6 and Figure 7 , a circular rotating plate 74 is integrally and coaxially provided on the second mounting shaft 712. The rotating plate 74 is used to more labor-savingly dial the rotation of the second mounting shaft 712. The rotating plate 74 is provided with an avoidance hole 741 for avoiding the slider 41, so that the slider 41 can pop out smoothly.

[0051] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
