[0039] Through the above - mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0040] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0041] It should be noted that in the description of the embodiments of the present application, the terms indicating the orientation or positional relationship such as "upper", "lower", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description, rather than indicating or implying that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of the present application.

[0042] In addition, it should be noted that the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more, unless otherwise specifically defined.

[0043] In this application, unless otherwise clearly specified and defined, terms such as "installed", "connected", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or a connection that allows mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] As described in the background art, in the prior art, a simple tooling includes a fixed shaft and a runner rotatably arranged on the fixed shaft. A handle is provided on the runner, and the electric tracing is abutted against the opposite surfaces of the fixed shaft and the handle. Rotating the handle drives the electric tracing to bend, realizing the one-way bending of the electric tracing. However, when two-way bending is required, the runner of the simple tooling can only move in one direction. In order to achieve the bending angle in the reverse direction, it is necessary to manually place the electric tracing in the reverse direction again so that the runner bends out the bending angle in the reverse direction, reducing the bending efficiency.

[0045] In view of this, the present application provides an armored electric tracing bidirectional bending device, which includes a base, a reel assembly, a straightening assembly, and a bending assembly arranged in sequence. The reel assembly is arranged on the base, and the electric tracing is wound around it through the reel assembly to supply power. The electric tracing is pulled so that the electric tracing rotates and extends from the reel assembly. The straightening assembly includes at least two rollers, each roller is rotatably arranged on the base, and each roller is located on opposite sides of the electric tracing to jointly clamp the electric tracing. The electric tracing moves between the two rollers to straighten the electric tracing. The bending assembly includes a fixing member, a cross bar, and at least two rotating wheels. The fixing member is arranged on the base, and each rotating wheel is connected by the cross bar. A channel for the electric tracing to pass through is formed between the two rotating wheels. The straightened electric tracing passes through this channel and then is bent by the two rotating wheels. When bending, one rotating wheel remains stationary, and the other rotating wheel disengages from the fixing member and drives the straightened electric tracing to rotate around one rotating wheel. After the electric tracing forms a bending arc, the rotating wheel returns to its original position, and then the extended part of the electric tracing is extended. At this time, the other rotating wheel remains stationary, and one rotating wheel disengages from the fixing member and drives the straightened electric tracing to rotate around the other rotating wheel, so that the electric tracing forms a bending arc opposite to the previous one, thus realizing the bidirectional bending of the electric tracing. The device realizes the bidirectional bending of the electric tracing with the assistance of the two rotating wheels, shortens the time wasted by manually re-placing the electric tracing in the reverse direction for bending, and improves the efficiency of bidirectional bending.

[0046] The following will combine Figures 1 to 4 with specific embodiments to describe the present application in detail.

[0047] Figure 1 is a schematic structural diagram of the armored electric tracing bidirectional bending device provided by the embodiment of the present application; Figure 2 is Figure 1 a schematic structural diagram of the rotating wheel and the cross bar in the middle; Figure 3 is Figure 1 a schematic structural diagram of the fixing member in the middle;

[0048] Figure 4 is Figure 1 a schematic structural diagram of the handle in the middle. It should be noted that, for the convenience of clearly describing the bending state of the electric tracing, Figure 1 10 in the middle represents the electric tracing, which will not be repeated hereinafter, and the arc dotted line represents the bending trajectory of the electric tracing.

[0049] The present application provides an armored electric tracing two-way bending device, including: a base 400 and a reel assembly 100, a straightening assembly 200, and a bending assembly 300 arranged in sequence; the reel assembly 100 is arranged on the base 400, and the reel assembly 100 is used for winding the electric tracing thereon; the straightening assembly 200 includes at least two rollers 220, each roller 220 is rotatably arranged on the base 400, and each roller 220 is respectively located on opposite sides of the electric tracing to jointly clamp the electric tracing; the bending assembly 300 includes a fixing member 310, a cross bar 330, and at least two rotating wheels 320, the fixing member 310 is arranged on the base 400, each rotating wheel 320 is connected by the cross bar 330, and a channel for the electric tracing to pass through is formed between the two rotating wheels 320; both of the two rotating wheels 320 are in contact with the fixing member 310, and one of the two rotating wheels 320 is configured to drive the electric tracing to rotate around the other when it is disengaged from the fixing member 310, so as to bend the electric tracing.

[0050] Specifically, the reel assembly 100 is arranged on the base 400. The reel assembly 100 is circular, and the electric tracing is wound onto the reel assembly 100. By pulling the extending end of the electric tracing, the reel assembly 100 is driven to rotate, so that the electric tracing rotates and extends from the reel assembly 100.

[0051] In order to improve the bending effect of the electric tracing, the electric tracing can be straightened before being bent. Therefore, a straightening assembly 200 is also arranged between the reel assembly 100 and the bending assembly 300. The straightening assembly 200 includes at least two rollers 220, and each roller 220 is rotatably arranged on the base 400. It should be noted that the roller 220 includes a roller shaft and a wheel. The roller shaft is arranged on the base 400, and the wheel is sleeved on the roller shaft, and the wheel can rotate around the roller shaft. Each roller 220 is respectively located on opposite sides of the electric tracing to jointly clamp the electric tracing, and the electric tracing passes through between the two rollers, so that the electric tracing is straightened.

[0052] To achieve a double - bending effect, a bending assembly 300 is further provided on the base 400. The bending assembly 300 includes a fixing member 310, a cross bar 330, and at least two rotating wheels 320. The fixing member 310 is disposed on the base 400. Each rotating wheel 320 is connected by the cross bar 330. Two rotating wheels 320 clamp the electric heat tracing. A channel for the electric heat tracing to pass through is formed between the two rotating wheels 320. Both of the two rotating wheels 320 are in contact with the fixing member 310. Exemplarily, after being straightened, the electric heat tracing extends a certain distance between the two rotating wheels 320 and then is bent by the two rotating wheels. When bending, one rotating wheel 320 remains stationary, and the other rotating wheel 320 disengages from the fixing member 310 and drives the straightened electric heat tracing to rotate around one rotating wheel 320 with the cross bar 330 as the radius, as shown in the +x direction in the figure. After the electric heat tracing forms a bending arc, the rotating wheel 320 returns to its original position. Then, the extended part of the electric heat tracing is extended again. At this time, the other rotating wheel 320 remains stationary, and one rotating wheel 320 disengages from the fixing member 310 and drives the straightened electric heat tracing to rotate around the other rotating wheel 320 with the cross bar 330 as the radius, as shown in the -x direction in the figure. After the electric heat tracing forms a bending arc opposite to the previous one, the rotating wheel 320 returns to its original position, thus achieving the double - bending of the electric heat tracing.

[0053] In the double - bending device according to the embodiment of the present application, the electric heat tracing is placed through the reel assembly 100, and the electric heat tracing is pulled to extend from the reel assembly 100 by rotation. Then, it is straightened by the straightening assembly 200. The straightened electric heat tracing extends a certain distance through the channel formed between the two rotating wheels 320 and then is bent by the two rotating wheels. When bending, one rotating wheel 320 remains stationary, and the other rotating wheel 320 disengages from the fixing member 310 and drives the straightened electric heat tracing to rotate around one rotating wheel 320. After the electric heat tracing forms a bending arc, the rotating wheel 320 returns to its original position. Then, the extended part of the electric heat tracing is extended again. At this time, the other rotating wheel 320 remains stationary, and one rotating wheel 320 disengages from the fixing member 310 and drives the straightened electric heat tracing to rotate around the other rotating wheel 320. After the electric heat tracing forms a bending arc opposite to the previous one, the rotating wheel 320 returns to its original position, thus achieving the double - bending of the electric heat tracing. Due to the assistance of the two rotating wheels 320, this device realizes the double - bending of the electric heat tracing, shortens the time wasted by manually re - placing the electric heat tracing in the reverse direction for bending, and improves the efficiency of double - bending.

[0054] In some embodiments, for the armored electric heat tracing double - bending device provided by the present application, the reel assembly 100 includes a fixed disk 110, a movable disk 120, and a variable - diameter disk 130. The fixed disk 110 includes a disk 111 and a fixed shaft 112 disposed on the disk 111. The disk 111 is disposed on the base 400. The movable disk 120 is rotatably disposed on the fixed shaft 112. The variable - diameter disk 130 is sleeved on the movable disk 120. The electric heat tracing is sleeved on the movable disk 120 and is in contact with the variable - diameter disk 130.

[0055] In specific implementation, the fixed disk 110 includes a fixed shaft 112 on a disk 111. The disk 111 is arranged on a base 400. The movable disk 120 is rotatably arranged on the fixed shaft 112. The movable disk 120 can rotate around the axis of the fixed shaft 112. The electric tracing is similar to a tape measure shape and is sleeved on the movable disk 120 and rotates synchronously with the movable disk 120. When in use, the extended end of the electric tracing is pulled to drive the movable disk 120 to rotate, and the electric tracing rotates and extends from the movable disk 120.

[0056] In some embodiments, the electric tracing is wound into coils of different specifications, resulting in different diameter sizes. The reel assembly 100 is further provided with a variable diameter disk 130. The variable diameter disk 130 is sleeved on the movable disk 120. The variable diameter disk 130 rotates with the movable disk 120. The variable diameter disk 130 abuts against the outer ring of the electric tracing. The variable diameter disk 130 is used to adapt to electric tracings of different diameters, improving the adaptability of the reel assembly 100 to different electric tracing specifications.

[0057] In addition, for the armored electric tracing two-way bending device provided by the present application, the variable diameter disk 130 includes a plurality of abutting members 131 and a plurality of elastic members 132. The abutting members 131 are connected to the movable disk 120 through the elastic members 132. The abutting members 131 are circumferentially arranged at intervals around the movable disk 120. The abutting members 131 are used to abut against the electric tracing.

[0058] In specific implementation, the abutting member 131 abuts against the outer ring of the electric tracing, and the elastic member 132 is in an extended state. As the electric tracing rotates and extends, the diameter of the outer ring of the electric tracing becomes smaller. At this time, the elastic member 132 contracts, driving the abutting member 131 to always abut against the outer ring of the electric tracing to adapt to different outer ring diameters of the electric tracing.

[0059] In some embodiments, at least one fixing buckle 133 is further provided on the variable diameter disk 130. The fixing buckle 133 is provided on the abutting member 131. The fixing buckle 133 abuts against the side surface of the electric heat tracing, restricting the electric tracing between the fixed disk 110 and the fixing buckle 133 to prevent the electric tracing from coming off the fixed disk 110.

[0060] It should be noted that the variable diameter disk 130 can abut against the inner ring of the electric tracing. The variable diameter disk 130 is used to adapt to electric tracings of different inner ring diameters. Exemplarily, the elastic member 132 extends or contracts to make the abutting member 131 abut against the inner ring diameter of the electric tracing. Specifically, the elastic member 132 can be a spring, and the abutting member 131 can be a stopper. The present application does not limit this.

[0061] In some embodiments, for the armored electric tracing two-way bending device provided by the present application, at least two card slots 313 are provided on the fixing member 310. The rotating wheel 320 abuts against the card slots 313 one by one.

[0062] In specific implementation, as Figure 3As shown, a card slot 313 is further provided on the fixing member 310. The card slot 313 is matched with the rotating wheel 320. When the card slot 313 is disengaged from the rotating wheel 320, it is convenient for the rotating wheel 320 to rotate around another rotating wheel 320 with the cross bar 330 as the radius, so as to bend the electric tracing. The card slot 313 is connected to the connecting member 312, which is convenient for the rotating wheel 320 to be embedded on the periphery of the pressing plate 311, so that the rotating wheel 320 remains stationary.

[0063] It should be noted that, in some embodiments, the rotating wheel 320 includes a large rotating wheel and a small rotating wheel. The diameter of the small rotating wheel is smaller than that of the large rotating wheel. The small rotating wheel is connected to the cross bar 330. The card slots 313 are arranged in one-to-one correspondence with the small rotating wheels. The large rotating wheel and the small rotating wheel are detachably connected. The electric tracing passes through between the two large rotating wheels. By assembling large rotating wheels with different diameters, the gap between the two large rotating wheels can be adjusted to adapt to electric tracings with different thicknesses.

[0064] In some embodiments, the armored electric tracing two-way bending device provided in the present application further includes a connecting member 312. Each rotating wheel 320 is connected by the connecting member 312. The connecting member 312 faces the base 400 and abuts against the base 400.

[0065] Specifically, the connecting member 312 is arranged on the rotating wheel 320 along the axial direction of the rotating wheel 320. The connecting member 312 faces the base 400 and is used to abut against the base 400.

[0066] In some embodiments, as Figure 4 shown, the connecting member 312 can be a push-type buckle. A sliding groove (not shown in the figure) adapted to the buckle is provided on the base 400. The sliding groove can be a channel for the electric tracing to pass through. When the buckle is pressed, the bottom of the connecting member 312 extends out and abuts against the sliding groove, which is convenient for rotating the rotating wheel 320. When the buckle is pressed again, the bottom of the connecting member 312 retracts and disengages from abutting against the sliding groove, so that the rotating wheel 320 remains stationary. Or, the connecting member 312 can be a push-type buckle. A fixing groove (not shown in the figure) adapted to the buckle is provided on the base 400. When the buckle is pressed, the bottom of the connecting member 312 extends out and abuts against the fixing groove, so that the rotating wheel 320 remains stationary; when the buckle is pressed again, the bottom of the connecting member 312 retracts and disengages from abutting against the fixing groove, which is convenient for the rotating wheel 320 to rotate.

[0067] In some embodiments, for the armored electric tracing two-way bending device provided in the present application, the number of the rollers 220 is multiple, and the rollers 220 are arranged at intervals in sequence.

[0068] Specifically, in order to enhance the straightening effect, the number of the rollers 220 can be set to be multiple. The rollers 220 are arranged at intervals in sequence, and the electric tracing passes through the rollers 220 in sequence.

[0069] In some embodiments, the armored electric tracing two-way bending device provided by the present application further includes an auxiliary tool slot 600, and the auxiliary tool slot 600 is arranged on the base 400.

[0070] Specifically, the auxiliary tool slot 600 is arranged on the base 400 and above the reel assembly 100. It should be noted that the auxiliary tool slot 600 is used to store tools such as multimeters and pliers.

[0071] In some embodiments, the shape and quantity of the auxiliary tool slot 600 can be determined according to actual usage requirements, and the present application does not limit this. Exemplarily, the shape of the auxiliary tool slot 600 can be square or circular, and the quantity of the auxiliary tool slot 600 can be two, as Figure 1 shown.

[0072] In some embodiments, a folding table corner is further arranged below the base 400. This folding table corner facilitates adjusting the height of the base 400. When the table corner is unfolded, the base 400 is raised, facilitating the operation of the operator. When the table corner is folded, the occupied space is reduced, facilitating storage.

[0073] In some embodiments of the armored electric tracing two-way bending device provided by the present application, the auxiliary tool slot 600 is located on one side of the reel assembly 100.

[0074] Since there is still a lot of space on both sides of the reel assembly 100, the auxiliary tool slot 600 can be arranged on any side of the reel assembly 100. Exemplarily, as Figure 1 shown, the auxiliary tool slot 600 is above the reel assembly 100.

[0075] In some embodiments of the armored electric tracing two-way bending device provided by the present application, the bending assembly 300 further includes a grip 340, and the grip 340 is arranged on the runner 320 and along the axial direction of the runner 320.

Exemplarily, the zero position of the measuring tool 500 is set in front of the runner 320, facilitating determining the initial position of the extending length of the electric tracing. When measuring, the electric tracing is extended along the measuring tool 500 to measure the required bending length of the electric tracing.

[0079] In some embodiments, there are no restrictions on the type of the measuring tool 500, as long as it can achieve the measuring function. Exemplary measuring tools 500 can be a meter stick or a tape measure.
