[0036] In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore, the present application is not limited by the specific embodiments disclosed below.

[0039] Embodiment 1

[0040] Referring to Figs. 1-2, the first embodiment of the present application provides a take-up device of an insulation resistance tester, which comprises a rebound assembly 100 including a base 101 and an elastic portion 102 arranged on the front side of the base 101; a take-up assembly 200 including a transmission portion 201 arranged on the front side of the elastic portion 102 and a take-up portion 202 arranged on the front side of the transmission portion 201; and a regulating assembly 300 including a movable portion 301 arranged on the front side of the take-up portion 202 and a locking portion 302 arranged on the side of the movable portion 301; wherein the locking portion 302 is connected with the base 101, and the take-up portion 202 is also connected with the base 101.

[0041] The winding part 202 can accommodate the detection line 202d of the insulation resistance tester. After the detection end 202d-1 of the detection line 202d is pulled out, the elastic part 102 can pull the detection line 202d back into the fixed cover 202b of the winding part 202 through the transmission part 201 and the winding part 202, so as to realize the winding function. The locking part 302 can be used in cooperation with the movable part 301. When the detection line 202d is pulled out of the fixed cover 202b, the control assembly 300 does not block the pulling out of the detection line 202d, but can block the reverse winding of the detection line 202d into the fixed cover 202b, so as to prevent the rebound assembly 100 from pulling the detection line 202d back after the user releases the hand. After the state of the locking part 302 is switched, the control assembly 300 no longer blocks the detection line 202d from returning to the fixed cover 202b, so that the rebound assembly 100 can pull the detection line 202d back into the fixed cover 202b through the winding assembly 200.

[0042] Embodiment 2

[0043] Referring to FIGS. 3-5, the second embodiment of the present application is different from the first embodiment in that the elastic part 102 includes a fixed column one 102a fixedly arranged at the center of the front side of the base 101 (note that the side close to the base 101 in the following description is referred to as the rear side, and the side away from the base 101 is referred to as the front side), a coil spring 102b fixedly arranged at one end of the fixed column one 102a, a movable block 102c arranged at the other end of the coil spring 102b, and a baffle 102d fixedly arranged on the circumferential surface of the fixed column one 102a, the movable block 102c being capable of moving synchronously with the end of the base 101; the base 101 is provided with a receiving groove 101a in the front part, the coil spring 102b and the movable block 102c are located in the receiving groove 101a, the baffle 102d is located in front of the coil spring 102b, the coil spring 102b is arranged between the base 101 and the baffle 102d, and the baffle 102d cooperates with the fixed groove to limit the coil spring 102b.

[0044] The transmission part 201 includes a rotating part one 201a rotatably arranged on the circumferential surface of the fixed column one 102a, a transmission frame 201b fixedly arranged on the circumferential side surface of the rotating part one 201a, and a transmission column 201c fixedly arranged on the front side of the movable block 102c, the transmission column 201c being movably arranged in the transmission frame 201b, when the coil spring 102b moves and drives the movable block 102c to move, the movable block 102c can drive the transmission frame 201b to rotate through the receiving segment column, so as to drive the rotating part one 201a to rotate.

[0045] The take-up part 202 comprises a rotating plate 202a fixedly arranged at the front side of the rotating member 201a, a fixed cover 202b rotatably arranged at the front side of the rotating plate 202a, a support 202c fixedly arranged between the fixed cover 202b and the base 101, the support 202c being capable of supporting and fixing the fixed cover 202b, the take-up part 202 further comprising a detection line 202d arranged between the fixed cover 202b and the rotating plate 202a, a rotating member 202e fixedly arranged on the rotating plate 202a, and an opening 202f formed on the circumferential surface of the fixed cover 202b; the rotating plate 202a is rotatably connected to the circumferential surface of the fixed column, the detection line 202d passes through the opening 202f, the inner side of the fixed cover 202b is provided with a space for the detection line 202d to move, and the rotating plate 202a can block the rear side of the fixed cover 202b to limit the detection line 202d in the fixed cover 202b.

[0046] The rotating member 202e is provided with a channel 202e-1. The detection line 202d comprises a connecting segment 202d-3 passing through the channel 202e-1, a winding segment 202d-2 adjacent to the connecting segment 202d-3, and a detection end 202d-1 adjacent to the winding segment 202d-2; the connecting segment 202d-3 is perpendicular to the rotating member 202e and located on the central axis of the rotating member 202e, the connecting segment 202d-3 extends to the outside of the fixed cover 202b, one end of the winding segment 202d-2 connected with the connecting segment 202d-3 is perpendicular to the connecting segment 202d-3, and a small segment of the winding segment 202d-2 connected with the connecting segment 202d-3 is located in the channel 202e-1, and the detection end 202d-1 is arranged outside the fixed cover 202b and the tail thereof can abut against the opening 202f to prevent the detection end 202d-1 from being retracted into the fixed cover 202b.

[0047] The winding segment 202d-2 can be pulled out by pulling the detection end 202d-1, so that the winding segment 202d-2 moves counterclockwise, because a small segment of the winding segment 202d-2 connected with the connecting segment 202d-3 is located in the channel 202e-1, the winding segment 202d-2 can drive the rotating member 202e to rotate counterclockwise synchronously when the winding segment 202d-2 moves, and the detection end 202d-1 can rotate counterclockwise under the driving of the winding segment 202d-2, the detection end 202d-1 is relatively short, and its rotation will not cause disorder of its placement.

[0048] The counterclockwise rotation of the rotating member two 202e can drive the rotating plate 202a to rotate synchronously with the rotating member one 201a, thereby driving the transmission frame 201b to rotate synchronously. Since the transmission column 201c is movably arranged in the transmission frame 201b, the transmission frame 201b can drive the end of the coil spring 102b connected with the movable block 102c to rotate counterclockwise, thereby tightening the coil spring 102b. The end of the coil spring 102b can generate a reverse pulling force on the transmission frame 201b through the movable block 102c and the transmission column 201c.

[0049] Pulling the detection end 202d-1 can pull the winding section 202d-2 out, thereby achieving the purpose of lengthening the detection line 202d. Loosing the detection end 202d-1, the coil spring 102b can pull the winding section 202d-2 back into the fixed cover 202b, thereby achieving the purpose of winding. In use, the winding section 202d-2 is pulled out to the required length, then the detection section is connected with the part to be detected, and the connecting section 202d-3 is inserted into the insulation resistance tester.

[0050] The rest of the structure is the same as that of example 1.

[0051] Example 3

[0052] Referring to FIGS. 6-8, the third embodiment of the present application is different from the second embodiment in that the movable part 301 includes a transmission ring 301a fixedly arranged on the front side of the rotating member two 202e, and a gear 301b fixedly arranged on the circumferential surface of the transmission ring 301a. The detection section passes through the transmission ring 301a, and the transmission ring 301a passes out of the outer surface of the fixed cover 202b.

[0053] The locking part 302 includes a fixed seat 302a fixedly arranged on the front side of the base 101, a groove 302b opened on the front part of the fixed seat 302a, a spring 302c fixedly arranged in the groove 302b, an abutting column 302d fixedly arranged on one end of the spring 302c, a control member 302e arranged between the abutting column 302d and the gear 301b, a fixed column two 302f fixedly arranged on the front side of the fixed cover 202b, and a control member 302g arranged on the front side of the control member 302e.

[0054] The regulating member 302e comprises a convex tooth surface 302e-1 capable of engaging with the gear 301b, a vertical surface one 302e-2, a vertical surface two 302e-3 adjacent to the vertical surface one 302e-2, and a convex surface 302e-4 adjacent to the vertical surface two 302e-3; the convex tooth surface 302e-1 is capable of engaging with the gear 301b, the vertical surface one 302e-2, the vertical surface two 302e-3 and the convex surface 302e-4 are all capable of contacting the circumferential surface of the abutting column 302d; the convex tooth surface 302e-1, the vertical surface one 302e-2 and the vertical surface two 302e-3 are all provided with two groups of mutually symmetrical surfaces, and the convex surface 302e-4 is located between the two vertical surface two 302e-3, and the regulating member 302e is regularly arranged in a left-right symmetrical manner as a whole.

[0055] Referring to FIGS. 6 and 7, the extension lines of the vertical surface one 302e-2 and the vertical surface two 302e-3 are perpendicular to each other, the front end of the fixed seat 302a is provided with a downward protrusion 302a-1, the groove 302b is located in the protrusion 302a-1, the protrusion 302a-1 of the base 101 is provided with a recess 302b-1 for the movement of the abutting column 302d, the circumferential surface of the abutting column 302d is connected with the end of the spring 302c and contacts the circumferential surface of the regulating member 302e, and the upper half of the abutting column 302d is always located in the groove 302b.

[0056] Referring to FIGS. 6 and 7, the circumferential surface of the abutting column 302d contacts the connection between the vertical surface one 302e-2 and the vertical surface two 302e-3 located on the left part of the regulating member 302e, and the convex tooth surface 302e-1 on the right part of the regulating member 302e engages with the gear 301b, the spring 302c makes the abutting column 302d abut against the surface of the regulating member 302e, which is the first state of the regulating assembly 300.

[0057] In the first state, the gear 301b is rotated counterclockwise, the convex teeth of the gear 301b can make the regulating member 302e have a tendency to rotate clockwise to the right, but the regulating member 302e is blocked by the abutting column 302d on the left side, so the regulating member 302e cannot rotate counterclockwise to the right, the gear 301b is stuck, because the gear 301b moves synchronously with the rotating member two 202e, the take-up portion 202 is also stuck and cannot rotate counterclockwise, so the winding wire cannot be pulled out.

[0058] If the gear 301b is rotated clockwise in this state, the protrusions of the gear 301b can make the control knob 302e have a tendency to rotate counterclockwise to the left, the vertical surface two 302e-3 on the left of the control knob 302e can press and abut the abutment column 302d, so that the abutment column 302d moves into the groove 302b and compresses the spring 302c, the abutment column 302d leaves the connection between the vertical surface one 302e-2 and the vertical surface two 302e-3, and only contacts the vertical surface two 302e-3, the gear 301b drives the control knob 302e to continue to rotate counterclockwise to the left, according to the known common sense, the meshing connection between the gears 301b enables the gears 301b to perform step-by-step movement, the protrusion surface 302e-1 of the control knob 302e enters the next step period, enters the recess 302b-1 between the protrusions on the gear 301b, the spring 302c makes the abutment column 302d rebound, the control knob 302e returns to the original state, the gear 301b continues to rotate, the control knob 302e cannot block the rotation of the gear 301b, and the abutment column 302d cannot pass the protrusion surface 302e-4 in this process; that is, in the first state, the gear 301b can only rotate clockwise, and the take-up portion 202 can wind the winding section 202d-2 back into the fixed cover 202b.

[0059] The process of switching the regulating assembly 300 from the first state to another state is as follows: manipulating the control lever to rotate to the left, the vertical surface two 302e-3 on the left part of the regulating element 302e can extrude and abut the abutment column 302d, so that it moves into the groove 302b and compresses the spring 302c, the control regulating element 302e continues to rotate counterclockwise to the left, the abutment column 302d is away from the abutment between the vertical surface two 302e-3 and the convex surface 302e-4, the convex surface 302e-4 extrudes the abutment column 302d to the bottom of the groove 302b closest to the bottom, after the convex surface 302e-4 passes through the abutment column 302d, the abutment column 302d abuts with the vertical surface two 302e-3 on the right part of the regulating element 302e, until the abutment column 302d contacts with the junction of the vertical surface one 302e-2 and the vertical surface two 302e-3 on the right part of the regulating element 302e, the vertical surface one 302e-2 on the right part is blocked by the abutment column 302d, and the state switching is completed, the regulating assembly 300 is switched to the second state, the circumferential surface of the abutment column 302d contacts with the junction of the vertical surface one 302e-2 and the vertical surface two 302e-3 on the right part of the regulating element 302e, the convex tooth surface 302e-1 on the left part of the regulating element 302e meshes with the gear 301b, and the spring 302c makes the abutment column 302d abut with the surface of the regulating element 302e. Because of the symmetrical arrangement of the regulating part itself and the foregoing, after the regulating assembly 300 is switched to the second state, the gear 301b can only rotate counterclockwise, and cannot rotate clockwise, that is, in the second state, the winding wire can be pulled out of the fixed cover 202b, but because the regulating assembly 300 cannot make the rotating part two 202e rotate clockwise, after the staff releases the detection line 202d, the coil spring 102b cannot indirectly make the rotating part two 202e rotate, and the winding wire can only be pulled out of the fixed cover 202b in one direction, without worrying about the problem that the winding wire returns to the fixed cover 202b after the hand is released.

[0060] It should be noted that when switching the state of the regulating assembly 300, the regulating element 302e will cause the gear 301b to move slightly, so do not switch the state when the detection line 202d is completely retracted into the fixed cover 202b or when the detection line 202d is pulled out the longest, and by reasonably setting the parameters of the coil spring 102b or using a coil spring 102b that can be adapted, a small winding section 202d-2 is left outside the opening 202f when the detection line 202d is retracted, leaving operation space for the regulating assembly 300.

[0061] In summary, when the regulating assembly 300 is in the second state, the detection line 202d can only be pulled out of the fixed cover 202b in one direction, and when the regulating assembly 300 is in the first state, the detection line 202d can only be retracted into the fixed cover 202b in one direction.

[0062] In summary, when the detection line 202d is not used, the regulating assembly 300 is in the first state, when the device is used, the detection end 202d-1 is used to pull out the winding section 202d-2, when the detection line 202d is pulled to a proper length, the detection end 202d-1 is connected with the part to be detected, and the end of the connecting section 202d-3 is connected with the insulation resistance tester; when the detection line 202d needs to be retracted, the two ends of the detection line 202d are disconnected, then the control member 302g is actuated to switch the regulating assembly 300 to the second state, the detection line 202d can be automatically retracted into the fixing cover 202b, and then the control member 302g is actuated to switch the regulating assembly 300 to the first state for next use.

[0063] The present application avoids the trouble caused by the winding and the arrangement of the line, and the device has a small size and is convenient to carry and place.

[0064] The rest of the structure is the same as that of the embodiment 2.

[0065] Embodiment 4

[0066] Referring to FIGS. 1-2, the fourth embodiment of the present application is different from the second embodiment in that the fixing seat 302a is provided with a clamp 400, the device can clamp the edge of the box of the insulation resistance tester, for the insulation resistance tester without the box, the device can also be fixed at a nearby position convenient for use through the clamp 400, further providing convenience for the user, the clamp 400 can provide a fulcrum for the device, avoiding the trouble of pulling the line while holding the device.

[0067] The rest of the structure is the same as that of the embodiment 3.
