Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric wire and cable, in particular to a power cord reel. BACKGROUND

[0002] The power cord reel is a device for automatically winding and unwinding the power cord, which is widely used in the fields of power tools, household appliances, industrial equipment, etc.

[0003] At present, the shell of the existing power cord reel is generally of a closed structure, and the shell contains key components such as a coil spring, a power cord and a power cord reel inside. In the long-term use process of the power cord reel, heat will be generated due to the power supply of the power cord and the winding and unwinding of the power cord on the power cord reel. The heat will accumulate inside the power cord reel, which will seriously affect the performance and service life of the power cord reel. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a power cord reel capable of solving the above technical problems.

[0005] To solve the above technical problems, the present application provides the following technical solutions:

[0006] A power cord reel, comprising:

[0007] A shell comprising a first shell cover and a second shell cover, the second shell cover being connected to the first shell cover so as to form an accommodation cavity with the first shell cover and the second shell cover, a first set of air vents being formed on one side wall of the first shell cover in the thickness direction of the power cord reel, and a second set of air vents being formed on one side wall of the second shell cover in the thickness direction of the power cord reel, the second set of air vents and the first set of air vents being respectively communicated with the accommodation cavity;

[0008] A power cord reel accommodated in the accommodation cavity and rotatably connected with the first shell cover and the second shell cover, respectively, and having a power output cord wound thereon;

[0009] A coil spring arranged outside the part of the first shell cover where the first set of air vents is formed and drivingly connected with the shaft of the power cord reel extending out of the first shell cover;

[0010] A first air vent cover plate covering the coil spring and connected with the first shell cover, for limiting the coil spring on the first shell cover;

[0011] A second air vent cover plate covering the part of the second shell cover where the second set of air vents is formed and connected with the second shell cover;

[0012] A power input line partially extends into a position between the second cover and the second air-permeable cover plate and is electrically connected with the power output line.

[0013] It can be understood that, by opening the first air-permeable hole group on the first cover and the second air-permeable hole group on the second cover, and connecting the first cover and the second cover with the first air-permeable cover plate and the second air-permeable cover plate having air-permeable holes respectively, the heat generated by the power reel during operation can be dissipated outward through the first air-permeable hole group, the second air-permeable hole group, the first air-permeable cover plate and the second air-permeable cover plate, so that the internal environment of the power reel can be effectively cooled, the steady-state operating temperature of each component in the power reel can be reduced, the performance degradation of the power reel caused by excessive temperature rise can be avoided, and the service life of the power reel can be prolonged.

[0014] In one of the embodiments, the first air-permeable hole group and / or the second air-permeable hole group is annular.

[0015] In one of the embodiments, the second cover protrudes at the position of the second air-permeable hole group and is formed with a connecting support, the power input line is clamped to the connecting support and is compressed and positioned by a limiting piece.

[0016] The second cover is formed with a limiting groove at a peripheral position of the connecting support, and the limiting groove can be clamped to the power input line.

[0017] It can be understood that the power output line is assembled to the connecting support and the limiting groove of the second cover in a clamped manner, so that the assembly of the power output line on the second cover can be facilitated.

[0018] In one of the embodiments, the power reel further comprises a rotation stopping mechanism, which is in transmission connection with the rotating shaft and is used for controlling the locking / unlocking of the rotating shaft; wherein the rotation stopping mechanism comprises:

[0019] a rotation stopping seat, which is sleeved on the rotating shaft and is in transmission connection with the rotating shaft, the rotation stopping seat is opened with a rotation stopping sliding groove, the rotation stopping sliding groove is annular, and the rotation stopping sliding groove is formed with a limiting portion;

[0020] a rotation stopping housing, which accommodates the rotation stopping seat and is connected with the housing;

[0021] a rotation stopping assembly, which is correspondingly arranged with the rotation stopping sliding groove, the rotation stopping assembly comprises a positioning pin and an elastic member, the positioning pin is slidingly installed in the rotation stopping housing, one end of the positioning pin is connected with the corresponding rotation stopping sliding groove in sliding connection after penetrating through the rotation stopping housing, and the elastic member is in pre-compression abutment on the positioning pin and is used for limiting the upper end of the positioning pin in the rotation stopping sliding groove;

[0022] When the end of the positioning pin is located at the position of the limiting part of the rotation-stopping chute, the end can provide a damping force for the rotation of the rotation-stopping seat, for limiting the rotation-stopping seat.

[0023] In one of the embodiments, a wire frame is mounted on the shell, and a wire outlet groove is formed in the wire frame and communicates with the accommodating cavity.

[0024] The power cord reel further comprises a positioner arranged between the power cord reel and the wire frame, the positioner comprising a positioner rod, a guide rod and a wire frame body, the positioner rod being rotatably mounted in the shell and being in transmission connection with the power cord reel, the guide rod being fixedly mounted in the shell, one end of the wire frame body being sleeved on the positioner rod and being in screw connection with the reciprocal teeth on the positioner rod, the other end of the wire frame body being sleeved on the guide rod and being in sliding connection with the guide rod.

[0025] The wire frame body faces the wire frame, and the power output cord wound on the power cord reel can pass through the wire frame body and extend out of the wire outlet groove.

[0026] It can be understood that the positioner rod of the positioner drives the wire frame body to reciprocally slide relative to the wire frame, so as to guide the power output cord passing through the wire frame body to move back and forth with the wire frame body, so that the power output cord can be uniformly and neatly wound on the power cord reel when the power cord reel winds the power output cord, which can prevent the power output cord from being stuck at the same position on the power cord reel, facilitate the use of the power cord reel by the user, and maximize the use of the storage space of the power cord reel, avoid the waste of space caused by the uneven winding of the power output cord on the power cord reel, and improve the volume utilization rate of the power cord reel.

[0027] In one of the embodiments, the wire frame body can reciprocally move along the length direction of the wire outlet groove under the driving of the positioner rod.

[0028] The first guide sleeve and the second guide sleeve are arranged along the radial direction of the guide rod, the first guide sleeve, the second guide sleeve and the wire frame body form a lead wire groove therebetween, and the power output cord can be sequentially arranged through the lead wire groove and the wire outlet groove.

[0029] It can be understood that the first guide sleeve and the second guide sleeve are arranged in the wire frame body in a rotatable manner, so as to reduce the frictional resistance of the power output cord when passing through the lead wire groove and extending out of the wire outlet groove.

[0030] In one embodiment, the conductor frame has a first connector, and a reciprocating tooth cover is connected to the first connector in a plug-in manner. The first connector is fitted onto the positioning rod, and the reciprocating tooth cover is screwed onto the reciprocating tooth.

[0031] In one embodiment, a transmission gear is formed on the locating rod, a drive gear is mounted on the power reel, and the drive gear and the transmission gear are connected by a conveyor belt.

[0032] In one embodiment, the power cord reel further includes a first mounting plate and a second mounting plate, the first mounting plate being foldably mounted on the housing, and the second mounting plate being slidably connected to the first mounting plate and detachably connected to the first mounting plate.

[0033] The power cord reel can be suspended and fixed by either the first or the second mounting plate.

[0034] Understandably, the above structural design allows users to choose to fix the cable reel to the target object via the first mounting plate or the second mounting plate, depending on their needs. This facilitates the hanging of the cable reel. Furthermore, when the cable reel is suspended via the second mounting plate and needs to be moved, the detachable connection between the first and second mounting plates allows the first mounting plate to slide off the second mounting plate. The cable reel can then be reinstalled in another desired location via the first mounting plate, eliminating the need to disassemble the second mounting plate, reducing operation time, and improving work efficiency.

[0035] In one embodiment, one end of the second hanger plate is formed with an abutment piece, which is capable of abutting and limiting the first hanger plate that is slidably connected to the second hanger plate;

[0036] When the abutment piece abuts against the first hanging plate and is limited in position, the abutment piece and the first hanging plate are detachably connected by threads.

[0037] Understandably, the above structural design facilitates the assembly and disassembly of the first mounting plate and the second mounting plate.

[0038] Due to the application of the above solution, this application has the following advantages compared with the prior art:

[0039] The power cord reel claimed in this application utilizes a first vent group on a first housing cover and a second vent group on a second housing cover. A first vent cover plate and a second vent cover plate, each with vent holes, are connected to the first and second housing covers respectively. This allows the heat generated during operation to dissipate outwards through the first vent group, the second vent group, the first vent cover plate, and the second vent cover plate. This effectively dissipates heat from the internal environment of the power cord reel, thereby reducing the steady-state operating temperature of the components and preventing performance degradation due to excessive temperature rise, thus extending the service life of the power cord reel.

[0060] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0061] like Figures 1 to 6As shown, a power cord reel 100 provided in one embodiment of this application includes a housing 10, a power cord reel 20, a coil spring 40, a first vent cover 50, and a second vent cover 60. The housing 10 includes a first cover 11 and a second cover 12. The second cover 12 is connected to the first cover 11 so that the first cover 11 and the second cover 12 enclose a receiving cavity 101. The first cover 11 has a first vent hole group 111 on one side wall in the thickness direction of the power cord reel 100, and the second cover 12 has a second vent hole group 121 on one side wall in the thickness direction of the power cord reel 100. The second vent hole group 121 and the first vent hole group 111 are respectively connected to the receiving cavity 101. The power cord reel 20 is received in the receiving cavity 101. The power supply reel 20 is rotatably connected to the first cover 11 and the second cover 12, respectively. A power output line 140 is wound on the power supply reel 20. A coil spring 40 is located on the outer side of the portion of the first cover 11 where the first vent hole group 111 is located, and is drively connected to the rotating shaft 112 extending from the first cover 11 on the power supply reel 20. A first vent cover plate 50 covers the coil spring 40 and is connected to the first cover 11, used to limit the coil spring 40 to the first cover 11. A second vent cover plate 60 covers the portion of the second cover 12 where the second vent hole group 121 is located and is connected to the second cover 12. A portion of the power input line 110 extends between the second cover 12 and the second vent cover plate 60 and is electrically connected to the power output line 140. Here, the first vent cover plate 50 has multiple first vent holes 51, and the second vent cover plate 60 has multiple second vent holes 61. It should be noted that the first vent cover 50 and the first shell cover 11 can be connected by screwing a third self-tapping screw 126 through the first vent cover 50 to the first shell cover 11.

[0062] As can be seen from the above, by opening a first vent group 111 on the first cover 11 and a second vent group 121 on the second cover 12, and connecting a first vent cover plate 50 with multiple first vent holes 51 and a second vent cover plate 60 with multiple second vent holes 61 to the first cover 11 and the second cover 12 respectively, the heat generated by the power cord reel 100 during operation can be dissipated to the outside through the first vent group 111, the second vent group 121, the first vent cover plate 50 and the second vent cover plate 60. This can effectively dissipate heat from the internal environment of the power cord reel 100, thereby reducing the steady-state operating temperature of each component in the power cord reel 100, preventing the power cord reel 100 from experiencing performance degradation due to excessive temperature rise, and extending the service life of the power cord reel 100.

[0063] like Figure 2 , Figure 6As shown, in one embodiment, the first vent group 111 and / or the second vent group 121 are annular. In this embodiment, both the first vent group 111 and the second vent group 121 are annular. It can be understood that in other embodiments, either the first vent group 111 or the second vent group 121 is annular. Here, the number of first vent groups 111 is set to be multiple, and the number of second vent groups 121 is also set to be multiple.

[0064] like Figure 2 As shown, in one embodiment, the second cover 12 protrudes at the location of the second vent hole group 121 and forms a connecting support 122. The power input line 110 is snapped onto the connecting support 122 and pressed and limited by the first limiting piece 123. The second cover 12 forms a limiting groove 124 on the periphery of the connecting support 122, and the limiting groove 124 can engage with the power input line 110. That is, the power output line 140 is assembled to the connecting support 122 and the limiting groove 124 of the second cover 12 in a snap-fit ​​manner, which facilitates the assembly of the power output line 140 on the second cover 12. Here, the first limiting piece 123 and the connecting support 122 can be connected by a screw threaded between the first self-tapping screw 125 passing through the first limiting piece 123 and the connecting support 122 to achieve the assembly connection of the first limiting piece 123 and the connecting support 122.

[0065] like Figure 1 , Figure 5 and Figure 7As shown, in one embodiment, a wire frame 13 is installed on the housing 10, and the wire frame 13 encloses a wire outlet groove 102, which communicates with the receiving cavity 101. The power reel 100 also includes a positioning device 30, which is located between the power reel 20 and the wire frame 13. The positioning device 30 includes a positioning rod 31, a guide rod 32, and a wire frame 33. The positioning rod 31 is rotatably installed inside the housing 10 and is connected to the power reel 20. The guide rod 32 is fixedly installed inside the housing 10. One end of the wire frame 33 is fitted onto the positioning rod 31 and screwed onto the reciprocating teeth 311 on the positioning rod 31. The other end of the wire frame 33 is fitted onto the guide rod 32 and is slidably engaged with the guide rod 32. The wire frame 33 faces the wire frame 13, and the power output wire 140 wound on the power reel 20 can pass through the wire frame 33 and extend outward from the wire outlet groove 102. In other words, the positioning rod 31 of the positioning device 30 drives the wire frame 33 to slide back and forth relative to the wire frame 13, thereby guiding the power output wire 140 passing through the wire frame 33 to move back and forth with the wire frame 33. In this way, when the power reel 100 winds up the power output wire 140, the power output wire 140 can be wound evenly and neatly on the power reel 20. This can prevent the power output wire 140 from getting stuck in the same position on the power reel 20, making it easier for the user to use the power reel 100. On the other hand, the power reel 20 can maximize the use of storage space and avoid space waste caused by uneven winding of the power output wire 140 on the power reel 20, thereby improving the volume utilization rate of the power reel 100.

[0066] like Figure 5 , Figure 7As shown, in one embodiment, the conductor frame 33 can reciprocate along the length of the outlet groove 102 under the drive of the positioning rod 31. A first guide sleeve 331 and a second guide sleeve 332 are rotatably connected inside the conductor frame 33. The first guide sleeve 331 and the second guide sleeve 332 are spaced apart along the radial direction of the guide rod 32. The first guide sleeve 331, the second guide sleeve 332, and the conductor frame 33 together form a lead groove 103, and the power output line 140 can sequentially pass through the lead groove 103 and the outlet groove 102. In other words, the first guide sleeve 331 and the second guide sleeve 332 are rotatably connected to the conductor frame 33, which reduces the frictional resistance encountered by the power output line 140 when it passes through the lead groove 103 and extends outward from the outlet groove 102. Here, the positioner 30 also includes a bolt 34 and a nut 35. The bolt 34 passes through the wire frame 33 and the first guide sleeve 331 and is connected to the nut 35 placed outside the wire frame 33, so that the first guide sleeve 331 is rotatably installed on the wire frame 33. How the second guide sleeve 332 is rotatably installed on the wire frame 33 can be referred to the installation method of the first guide sleeve 331, which will not be elaborated here.

[0067] like Figure 3 , Figure 7 As shown, in one embodiment, the conductor frame 33 has a first connecting joint 333, and a reciprocating tooth cover 334 is connected to the first connecting joint 333 by a plug-in engagement. The first connecting joint 333 is fitted onto the positioning rod 31, and the reciprocating tooth cover 334 is screwed onto the reciprocating tooth 311. That is, by utilizing the threaded engagement between the reciprocating tooth cover 334 and the reciprocating tooth 311, while the positioning rod 31 drives the reciprocating tooth 311 to rotate, the first connecting joint 333 can reciprocate on the positioning rod 31 under the drive of the reciprocating tooth cover 334, thereby driving the conductor frame 33 to reciprocate. Here, a second limiting piece 335 is threadedly connected to the first connecting joint 333. Specifically, the second limiting piece 335 and the first connecting joint 333 can be connected by a second self-tapping screw 336 passing through the second limiting piece 335 and the first connecting joint 333, so as to realize the assembly connection between the second limiting piece 335 and the first connecting joint 333, thereby limiting the reciprocating tooth cover 334 to the first connecting joint 333.

[0068] like Figure 3As shown, in one embodiment, a transmission gear 312 is formed on the locating rod 31, and a drive gear 120 is installed on the power reel 20. The drive gear 120 and the transmission gear 312 are connected by a conveyor belt 130. That is, when the power reel 100 is working, when a person pulls the power output cable 140 wound on the power reel 20, the power reel 20 rotates under the drive of the power output cable 140, and drives the drive gear 120 to rotate synchronously. By using the conveyor belt 130, the transmission gear 312 on the locating rod 31 and the locating rod 31 together can be driven to rotate, and the reciprocating gear 311 on the locating rod 31 can be driven to rotate.

[0069] like Figure 1 , Figure 8 and Figure 9 As shown, in one embodiment, the power cord reel 100 further includes a first mounting plate 70 and a second mounting plate 80. The first mounting plate 70 is foldably mounted on the housing 10, and the second mounting plate 80 is slidably connected to the first mounting plate 70 and detachably connected to the first mounting plate 70. The power cord reel 100 can be suspended and fixed by the first mounting plate 70 or the second mounting plate 80. This allows users to choose to fix the power cord reel 100 to the target object via the first mounting plate 70 or via the second mounting plate 80, depending on their needs. This facilitates the hanging of the power cord reel 100. Furthermore, when the power cord reel 100 is suspended via the second mounting plate 80 and needs to be moved, the detachable connection between the first mounting plate 70 and the second mounting plate 80 allows the first mounting plate 70 to slide off the second mounting plate 80. In this way, the power cord reel 100 can be re-fixed to another desired location via the first mounting plate 70, eliminating the need to disassemble the second mounting plate 80, reducing operation time, and improving work efficiency. Here, the first hanging plate 70 is a ceiling hanger, and the first hanging plate 70 has a first hanging hole 71. The first hanging plate 70 can be installed and fixed to the ceiling through the first hanging hole 71, wherein there are three first hanging holes 71; the second hanging plate 80 is a wall hanger, and the second hanging plate 80 has a second hanging hole 84. The second hanging plate 80 can be installed and fixed to the wall through the second hanging hole 84, wherein there are six second hanging holes 84.

[0070] like Figure 1 , Figure 8 and Figure 9As shown, in one embodiment, abutment piece 81 is formed at one end of the second bracket plate 80. The abutment piece 81 can abut and limit the first bracket plate 70, which is slidably connected to the second bracket plate 80. When the abutment piece 81 abuts and limits the first bracket plate 70, the abutment piece 81 and the first bracket plate 70 are detachably connected by threads, which facilitates the assembly and disassembly of the first bracket plate 70 and the second bracket plate 80. Specifically, the abutment piece 81 and the first bracket plate 70 can be screwed together by screws or bolts (not shown) passing through the abutment piece 81 to achieve the assembly connection between the first bracket plate 70 and the second bracket plate 80.

[0071] like Figure 1 , Figure 8 and Figure 9 As shown, in one embodiment, the second hanging plate 80 includes a hanging plate 82 and multiple sets of abutment slides 83. The multiple sets of abutment slides 83 are arranged sequentially at intervals along the length direction of the hanging plate 82, and a sliding groove 801 is formed between the multiple sets of abutment slides 83 and the hanging plate 82. The sliding groove 801 can be inserted and engaged with the first hanging plate 70 to make the first hanging plate 70 and the second hanging plate 80 slidably connected. Each set of abutment slides 83 includes two abutment slides 83, which are disposed on both sides of the first hanging plate 70 and respectively abut against and limit the thickness of the hanging plate 82. In other words, the first mounting plate 70 is connected to the second mounting plate 80 via a plug-in fit and abuts against the mounting plate 82 of the second mounting plate 80. This not only facilitates the assembly of the first mounting plate 70 onto the second mounting plate 80 and improves the stability of the assembly, but also meets the requirement for a detachable connection between the first and second mounting plates 70. Here, the number of abutment sliders 83 is configured as three sets. It is understood that in other embodiments, the number of abutment sliders 83 may be two sets, four sets, or other numbers, which will not be elaborated here.

[0072] like Figures 10 to 14As shown, in one embodiment, the power cord reel 100 further includes an anti-rotation mechanism (not shown), which is tractively connected to the rotating shaft 112 and used to control the locking / unlocking of the rotating shaft 112. The anti-rotation mechanism includes an anti-rotation seat 91, an anti-rotation housing 92, and an anti-rotation assembly 93. The anti-rotation seat 91 is fitted onto the rotating shaft 112 and tractively connected to it. An anti-rotation groove 911 is formed on the anti-rotation seat 91. The anti-rotation groove 911 is annular and forms a limiting portion 912. The anti-rotation housing 92 houses the anti-rotation seat 91 and is connected to the housing 10. The anti-rotation assembly 93 is correspondingly provided with the anti-rotation groove 911. The anti-rotation assembly 93 includes a positioning pin 931 and an elastic element 932. The positioning pin 931 is slidably installed inside the anti-rotation housing 92. One end of the positioning pin 931 passes through the anti-rotation housing 92 and is slidably connected to the corresponding anti-rotation groove 911. The elastic element 932 abuts against the positioning pin 931 in a pre-compressed manner to limit the upper end 9311 of the positioning pin 931 located in the anti-rotation groove 911. When the end 9311 of the positioning pin 931 is located at the limiting part 912 of the anti-rotation groove 911, the end 9311 can provide a damping force to the rotation of the anti-rotation seat 91 to limit the rotation of the anti-rotation seat 91. Here, the number of positioning pins 931 is configured as two, and the two positioning pins 931 are symmetrically arranged on both sides of the anti-rotation seat 91. Each positioning pin 931 is respectively installed with an elastic element 932 in a compressed manner between itself and the anti-rotation housing 92. Specifically, the elastic element 932 can be a spring, a rubber sleeve, or other highly elastic accessories.

[0073] As can be seen from the above, when the user pulls the power output cable 140 wound on the power reel 20 by hand, the power reel 20 rotates under the drive of the power output cable 140. The power reel 20 can drive the anti-rotation seat 91 to rotate through the rotating shaft 112, and cause the coil spring 40 to store energy. The end 9311 of the positioning pin 931 slides into the limiting part 912 of the anti-rotation groove 911. When the user releases the pull on the power output cable 140 by hand, the end 9311 of the positioning pin 931 and the anti-rotation groove 911 stop the rotation. The limiting part 912 of the rotating groove 911 abuts against the limiting part, and the positioning pin 931 is locked in the anti-rotation housing 92 in the rotation direction of the anti-rotation seat 91. In this way, the positioning pin 931 can finally lock the anti-rotation seat 91 in the rotation direction and achieve the purpose of locking the power output line 140. Afterwards, if the power output line 140 is pulled by hand, the anti-rotation seat 91 can be driven to rotate again, and the end 9311 of the positioning pin 931 can slide in the anti-rotation groove 911 of the anti-rotation seat 91.

[0074] It should be noted that during the process of manually pulling the power output line 140, when the manual releases the pull on the power output line 140 and the end 9311 of the positioning pin 931 is in the anti-rotation groove 911 except for the limiting part 912, since the end 9311 of the positioning pin 931 is not locked by the corresponding part on the anti-rotation groove 911, the anti-rotation seat 91 can automatically retract the power output line 140 under the drive of the energy-storing coil spring 40.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
