[0044] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0045] In the prior art, the grounding wire is usually wound manually, which means the grounding wire is repeatedly wound and stacked manually until the entire grounding wire is completely wound. Therefore, manual winding usually results in a loose coil caused by different coil circumferences, and the manual winding speed is slow, which reduces the winding efficiency.
[0046] In order to overcome the defects in the prior art, the present application provides a grounding wire take-up device, including a box body, a take-up wheel, a rotating shaft and a circumferential fixing part; the rotating shaft is rotatably arranged in the box body, the take-up wheel is used for winding and storing the grounding wire, one end of the take-up wheel is provided with a connecting shaft, and the take-up wheel is movably connected to one end of the rotating shaft through the connecting shaft; the take-up wheel moves relative to the rotating shaft to change the relative position of the take-up wheel in the axial direction of the rotating shaft, so that the take-up wheel can be extended out of the box body or retracted into the box body; when the take-up wheel is extended out of the box body, the circumferential fixing part acts on the rotating shaft and the connecting shaft respectively, so as to realize that the take-up wheel rotates coaxially and synchronously with the rotating shaft; the present application is used to solve the problems of loose coil and slow take-up speed of the manually wound grounding wire.
[0047] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.
[0048] Figure 1 A schematic diagram of a ground wire take-up device is provided for an embodiment of the present application.
[0049] Figure 2 A second schematic diagram of a ground wire take-up device is provided for an embodiment of the present application.
[0050] Figure 3 A third schematic diagram of a ground wire take-up device is provided for an embodiment of the present application.
[0051] See also Figure 1 , Figure 2 and Figure 3 As shown, a ground wire take-up device includes a box body 100, a take-up wheel 200, a rotating shaft 300 and a circumferential fixing member 400;
[0052] The rotating shaft 300 is rotatably arranged in the box body 100, and the take-up wheel 200 is used for winding and storing the ground wire. A connecting shaft 210 is arranged at one end of the take-up wheel 200, and the take-up wheel 200 is movably connected to one end of the rotating shaft 300 through the connecting shaft 210;
[0053] The take-up wheel 200 moves relative to the rotating shaft 300 to change the relative position of the take-up wheel 200 on the vertical plane, so that the take-up wheel 200 can be extended out of the box 100 or retracted into the box 100;
[0054] When the take-up wheel 200 extends out of the box body 100 , the circumferential fixing member 400 acts on the rotating shaft 300 and the connecting shaft 210 respectively, so as to realize the synchronous rotation of the take-up wheel 200 following the rotating shaft 300 .
[0055] Exemplarily, one end of the rotating shaft 300 is rotatably set on the inner wall of the box body 100. Common rotation settings include bearing rotation settings, which are all existing technologies and will not be repeated here. In particular, the axial direction of the rotating shaft 300 is set parallel to the horizontal plane; the axis of the connecting shaft 210 is colinear with the axis of the take-up wheel 200, so that the rotation of the take-up wheel 200 is driven by the connecting shaft 210.
[0056] It should be noted that the take-up wheel 200 moves relative to the rotating shaft 300 to change the relative position of the take-up wheel 200 on the vertical plane. More specifically, it can be understood that in the axial direction of the rotating shaft 300, when the take-up wheel 200 moves away from the rotating shaft 300, the take-up wheel 200 extends out of the box 100; when the take-up wheel 200 moves close to the rotating shaft 300, the take-up wheel 200 is retracted into the box 100; according to the prior art, it can be known that the ground wire is wound on the take-up wheel 200. In the initial state, the take-up wheel 200 is retracted into the box 100. When the ground wire needs to be wired, the take-up wheel 200 is retracted into the box 100 according to the prior art. In the above method, the take-up wheel 200 is extended out of the box body 100, and then the connecting shaft 210 and the rotating shaft 300 are limited to be in a coaxial state through the circumferential fixing member 400, and at this time, the connecting shaft 210 and the rotating shaft 300 do not rotate relative to each other, so that the take-up wheel 200 can be rotated with the central axis of the rotating shaft 300 as the rotating axis, and the take-up wheel 200 can be rotated to lay or reel in the grounding wire; at this point, the wiring or reeling of the take-up wheel 200 is carried out outside the box body 100, and the grounding wire will not collide or rub against the box body 100, and there will be no abutment and jamming.
[0057] In some embodiments, the connecting shaft 210 is hinged to one end of the rotating shaft 300 .
[0058] The circumferential fixing member 400 is a fixed sleeve, which is sleeved on the rotating shaft 300 and slides in the axial direction of the rotating shaft 300 .
[0059] When the connecting shaft 210 rotates to be coaxial with the rotating shaft 300 , the fixed sleeve is sleeved on the rotating shaft 300 and the connecting shaft 210 .
[0060] Exemplarily, a single-ear hinge seat is provided at one end of the rotating shaft 300, and a double-ear hinge seat is provided at the end of the connecting shaft 210 away from the take-up wheel 200, and the single-ear hinge seat is hinged between the double-ear hinge seats.
[0061] It should be noted that, in the present embodiment, the take-up wheel 200 is folded downward, that is, the connecting shaft 210 and the take-up wheel 200 are both located below the rotating shaft 300, and the take-up wheel 200 is now stored in the box 100; the take-up wheel 200 is folded upward until the connecting shaft 210 and the rotating shaft 300 are coaxial, and at this time, the fixed sleeve is slid toward the hinge of the connecting shaft 210 and the rotating shaft 300, and the fixed sleeve simultaneously sleeves the connecting shaft 210 and the rotating shaft 300, and the connecting shaft 210 cannot rotate relative to each other The shaft 300 rotates; at this time, the take-up wheel 200 flips over relative to the rotating shaft 300, that is, the take-up wheel 200 moves away from the rotating shaft 300, and finally, after the connecting shaft 210 and the rotating shaft 300 are coaxial, the take-up wheel 200 extends out of the box body 100; in this way, the hinged connection between the connecting shaft 210 and the rotating shaft 300 has the characteristic of a simple connection method; in addition, when the take-up wheel 200 is in the retracted state, it is located below the rotating shaft 300, thereby reducing the horizontal size of the box body.
[0062] In other embodiments, alternatively, a sleeve groove is provided at one end of the connecting shaft 210 away from the take-up wheel 200, and a first positioning hole is provided on the groove wall of the sleeve groove, and the circumferential fixing member 400 is a positioning bolt, which is screwed into the first positioning hole; the sleeve groove is sleeved to one end of the rotating shaft 300, and a second positioning hole is provided on the circumferential wall of the rotating shaft 300. At this time, the connecting shaft 210 and the rotating shaft 300 are in a coaxial state at all times; in the initial state, the take-up wheel 200 is stored in the box body 100, and the first positioning hole and the second positioning hole are misaligned. Then, the take-up wheel 200 is moved in a direction away from the rotating shaft 300 until the take-up wheel extends out of the box body 100. After the first positioning hole and the second positioning hole are aligned, the positioning bolt is rotated so that the positioning bolt is simultaneously inserted into the first positioning hole and the second positioning hole, thereby limiting the circumferential rotation of the connecting shaft 210 relative to the rotating shaft 300.
[0063] In some embodiments, one end of the rotating shaft 300 away from the connecting shaft 210 passes through the side wall of the box body 100 and protrudes out of the box body 100 .
[0064] One end of the rotating shaft 300 away from the connecting shaft 210 protrudes out of the box body 100, and the rotating shaft 300 can be operated to rotate through this end, which indirectly makes the rotation operation of the take-up wheel 200 more convenient.
[0065] In some embodiments, one end of the rotating shaft 300 protruding from the housing 100 is provided with a polygonal column 500 with at least three sides, and the polygonal column 500 is used to be engaged with the output end of an external power source so that the external power source drives the rotating shaft 300 to rotate.
[0066] For example, see Figure 3 The edges of the polygonal column 500 can be three sides or more, which is not limited here.
[0067] It should be noted that, taking the three-sided polygonal column 500 as an example, if the rotating shaft 300 is rotated manually, a wrench with a triangular edge is used to rotate the rotating shaft 300; if the rotating shaft 300 is rotated by a motor, a polygonal edge is designed on the output shaft of the motor to match the polygonal column 500.
[0068] It can be seen from the above that the assembly of the polygonal column 500 is more reliable, which is beneficial to improving the stability of the rotation of the rotating shaft 300.
[0069] In some implementations, a sunken annular groove 220 for wire winding is disposed on the outer peripheral wall of the wire winding wheel 200 ; and at least one wire end fixing groove 230 is disposed on the inner side wall of at least one sunken annular groove 220 .
[0070] The grounding end of the grounding wire is inserted into the wire end fixing slot 230 to fix the grounding end.
[0071] Exemplarily, the sunken annular groove 220 is sunken toward the axis of the take-up wheel 200 on the side wall of the take-up wheel 200 .
[0072] Exemplarily, a wire end fixing groove 230 is provided on one or two inner side walls of the sunken annular groove 220, and the number of wire end fixing grooves 230 on the same side wall is one or more, without limitation at this time; preferably, this embodiment takes an example in which one of the inner side walls is provided with a wire end fixing groove 230.
[0073] It should be noted that the two ends of the existing grounding wire are respectively a grounding end and a three-phase end (the three-phase end has three three-phase short-circuit grounding wires). When winding the wire, the grounding end is used as the starting end of winding; in order to better fix the grounding end, initially, the grounding end is first inserted into the wire end fixing groove 230, and then the winding wheel 200 can continue to be rotated to wind the grounding wire.
[0074] In some embodiments, in the axial direction of the take-up wheel 200 , the inner side wall of the sunken annular groove 220 is inclined from the end of the take-up wheel 200 to the middle of the end of the take-up wheel 200 .
[0075] The wire end fixing groove 230 is disposed on the inner side wall of the inclined sunken annular groove 220 and extends along the axial direction of the wire take-up wheel 200 .
[0076] A fixing rod 240 is disposed in the wire end fixing groove 230 , and the grounding end of the grounding wire is inserted between the wire end fixing groove 230 and the fixing rod 240 to clamp and fix the grounding end of the grounding wire.
[0077] Figure 4 A fourth schematic diagram of a ground wire take-up device is provided for an embodiment of the present application.
[0078] Figure 5 for Figure 4 Enlarged view of point A in the middle.
[0079] For example, see Figure 4 and Figure 5 The cross section of the sunken annular groove 220 on the take-up wheel 200 is an inverted trapezoid with an open top; thus, in the axial direction of the take-up wheel 200, the inner side wall of the sunken annular groove 220 is inclined from the end of the take-up wheel 200 to the middle of the take-up wheel 200.
[0080] Exemplarily, in the axial direction of the take-up wheel 200, the cross-section of the wire end fixing groove 230 is a right triangle, and the hypotenuse of the right triangle is located on the inclined surface of the sunken annular groove 220; thus, the notch of the wire end fixing groove 230 is located on the inner side wall of the sunken annular groove 220 and is arranged toward the middle of the take-up wheel 200.
[0081] It should be noted that the recessed annular groove 220 is an inverted trapezoidal structure. When the grounding wire is wound into the recessed annular groove 220, the inclined surfaces on both sides of the recessed annular groove 220 effectively bring the grounding wire closer to the middle of the take-up wheel 200 to prevent the grounding wire from being loose. In addition, the notch of the wire end fixing groove 230 is arranged toward the middle of the take-up wheel 200. The effect is that after the grounding end of the grounding wire is plugged into the wire end fixing groove 230, the grounding wire extends toward the middle of the recessed annular groove 220, so that the other parts of the grounding wire can be quickly wound into the recessed annular groove 220; more importantly, the notch of the wire end fixing groove 230 is located on the inner side wall of the recessed annular groove 220, so the upper part of the wire end fixing groove 230 is in an open state. In this way, a fixing rod 240 is horizontally arranged at the upper part of the wire end fixing groove 230. After the wiring terminal is plugged into the wire end fixing groove 230, the fixing rod 240 forms a limit fixation on the top of the grounding terminal.
[0082] In some embodiments, the box body 100 includes a main box 110 and a box door 120 , and the box door 120 is rotatably disposed on one side of the main box 110 .
[0083] The rotating shaft 300 is disposed on the main box 110 .
[0084] Exemplarily, the box body 100 is a rectangular box, one side of the main box 110 is an opening structure, and a box door 120 is rotatably provided on one side of the opening, and the box door 120 is used to close or open the opening.
[0085] It should be noted that, in combination with the above embodiments, it can be known that the take-up wheel 200 extending out of the box body 100 refers to extending out of the opening; therefore, the rotating shaft 300 is rotatably arranged on the side wall of the main box 110 opposite to the opening, and at the same time, the rotating shaft 300 is perpendicular to the side wall where it is located.
[0086] In some embodiments, at least one carrying ring 600 is disposed on the outer side wall of the main box 110 .
[0087] And / or, at least one carrying ring 600 is provided on the top wall of the main box 110 .
[0088] Exemplarily, the number of the carrying pull rings 600 can be one or more, which is not limited here.
[0089] It should be noted that one carrying pull ring 600 can be set on the outer wall of one of the side walls close to the opening; when there are two carrying pull rings 600, one carrying pull ring 600 can be set on each outer wall of the side wall close to the opening, and more preferably, the two carrying pull rings 600 are symmetrically arranged; the carrying pull ring 600 can be used to lift the box body 100 as a whole for easy transportation.
[0090] Alternatively, other portable structures may also be provided with grooves directly on the side wall of the main box 110, and the portable structure may also be lifted by grasping the grooves.
[0091] In some embodiments, a wire outlet hole 700 is provided on the box door 120 so that the three-phase short-circuit grounding wire at the end of the grounding wire can be led out through the wire outlet hole 700 .
[0092] It should be noted that the three-phase end of the grounding wire is the last to be reeled in. In order to be able to quickly find the three-phase end when wiring, the three-phase end is usually not wound onto the take-up wheel 200. In this way, the three-phase end usually passes through the outlet hole 700 from the inside to the outside and is exposed outside the box door 120, so that the three-phase end can be quickly found when the box door 120 is opened for wiring. At this time, the three-phase end can be pulled back to the inside of the box door 120, and then wiring can be carried out.
[0093] In some embodiments, a notch 710 is provided on the side of the box door 120 , and the notch 710 is connected to the wire outlet hole 700 , so that the three-phase short-circuit grounding wire can be inserted into the wire outlet hole 700 through the notch 710 .
[0094] Exemplarily, the wire outlet hole 700 is a strip hole, which is arranged along the width direction of the box door 120. A notch 710 is provided on the other side of the side wall of the strip hole which is away from the box door 120 and is rotatably connected to the main box 110. The function of the notch 710 is that the three-phase end of the grounding wire can be directly inserted into or taken out of the wire outlet hole 700 through the notch 710, which is more convenient and quick.
[0095] In some embodiments, a grounding wire fixing buckle 800 is provided on one side of the box door 120 away from the main box 110, and at least three bayonet holes 810 are provided on the grounding wire fixing buckle 800, and each three-phase short-circuit grounding wire is buckled in each bayonet hole 810. Exemplarily, the bayonet hole 810 is a U-shaped bayonet hole.
[0096] It should be noted that, in the final state of wire collection, the three-phase end finally passes through the outlet hole 700 and is located outside the box door 120. In order to avoid the three-phase end from drooping and being damaged by friction with the ground, or the three-phase end colliding with other external objects, the three three-phase short-circuit grounding wires can be respectively clamped in a clamp 810; more preferably, in order to increase the height position of the end of the three-phase short-circuit grounding wire, the grounding wire fixing buckle 800 is located above the outlet hole 700; thus, the three-phase short-circuit grounding wire passes through the outlet hole 700, is bent upward and clamped in the clamp 810.
