Description

TECHNICAL FIELD

[0001] The utility model relates to the cable reel field, concretely relates to a double ring frame type cable reel based on rolling bearing and electricity terminal. BACKGROUND

[0002] In many industrial and civil scenes, such as power construction, equipment maintenance, mobile appliance use and the like, often need to use the cable reel to take off the cable. The existing cable reel is poor in stability in the bidirectional pulling process, and in the occasion needing to be electrified, the connection structure of the cable and the power supply is not reliable enough, and problems such as poor contact are prone to occur, which affects normal use. At the same time, the cable is prone to disorder winding, disorder winding and the like in the winding process, which reduces the use efficiency and service life of the cable reel.

[0003] For the improvement of the cable reel and the related technology of the electric connector, the corresponding solution method has been given in the existing patent document, for example, the connector of the one-way winding of the electric wire disclosed in the patent document CN211254846U. However, there are still some limitations, the patent can only realize the one-way winding of the electric wire, and cannot meet the demand of the bidirectional pulling of the cable in actual application. Moreover, the patent mainly focuses on the protection of the electric wire turning position, and the reliability of the connection of the cable and the power supply and the problem of the orderly winding of the cable in the winding process are not effectively solved.

[0004] Therefore, it is of great significance to develop a double ring frame type cable reel based on rolling bearing and electricity terminal to break through the bottleneck of the existing technology, meet the demand of the bidirectional pulling stability of the cable reel, the reliability of the cable connection and the orderliness of the winding in actual application. SUMMARY

[0005] The utility model aims at providing a double ring frame type cable reel based on rolling bearing and electricity terminal to solve the problems of poor stability, unreliable cable connection and disorder winding in the prior art.

[0006] The technical scheme of the utility model is as follows:

[0007] A double ring frame type cable reel based on rolling bearing and electricity terminal, comprising a cable, an outlet cable binder, an outer circular ring frame, an inner circular ring frame, a fixed shaft, an electricity terminal and a rolling bearing.

[0008] The rolling bearing is a deep groove ball bearing, which can bear radial and certain axial load. The outlet cable organizer is arranged on the outer ring of the winding device, so that the cable can be neatly wound on the outer ring. The outer ring frame rotates around the inner ring frame, and the inner circle of the outer ring frame is in contact with the outer circle of the inner ring frame, and the inner circle of the inner ring frame is matched with the outer ring of the rolling bearing. The cable is arranged inside the winding device and connected with the annular structure at the bottom of the power terminal, and keeps close contact during mutual sliding. The power terminal is integrated on the inner ring frame, and the terminal extends outward and is connected with the external power source.

[0009] The deep groove ball bearing has the characteristics of bearing radial load and certain axial load. During work, when the cable is pulled in two directions, forces in different directions act on the winding device structure. The deep groove ball bearing uniformly disperses the radial force through the cooperation of the internal rolling body and the raceway, and effectively offsets the axial force along the rotation axis direction, thereby reducing the shaking between the inner ring and the outer ring and ensuring the rotation stability.

[0010] The annular structure surface at the bottom of the power terminal is provided with a conductive coating. During the two-way pulling of the cable, the cable wire will slide relative to the annular structure at the bottom of the power terminal, and the conductive coating enhances the conductivity and wear resistance to ensure that the current can pass smoothly in dynamic sliding.

[0011] The cable wire and the annular structure at the bottom of the power terminal keep close contact during mutual sliding to ensure power supply. During the two-way pulling of the cable, the cable wire will slide relative to the annular structure at the bottom of the power terminal. In order to ensure continuous and stable power supply during such relative sliding, elastic structure design and low-damping conductive material are adopted between the two to ensure close contact. Including but not limited to the following ways, on the one hand, the surface of the annular structure at the bottom of the power terminal is specially treated and provided with a conductive coating to enhance its conductivity and wear resistance, reduce the increase of contact resistance and surface wear caused by sliding friction. On the other hand, the connection mode of the cable wire and the annular structure is also carefully designed to ensure that the two always maintain sufficient contact area and good contact pressure during relative sliding, so as to ensure that the current can pass smoothly, meeting the needs of the winding device for cable power supply during work.

[0012] The outlet cable organizer is used to neatly wind the cable on the outer ring frame. When the cable is pulled out or retracted, the outlet cable organizer will adjust the constraint and guidance of the cable in real time according to the movement direction and speed of the cable. During the process of pulling out the cable, the guide outlet ensures that the cable leaves the outer ring frame at a proper angle and tension, so that the cable can maintain a straight line in the external space, reducing damage caused by excessive bending. When the cable is retracted, the guide wheel guides the cable to accurately wind on the outer ring frame, tightly arranged layer by layer, forming a neat winding layer.

[0013] Furthermore, the neat winding also makes the cable reel more stable during use, and does not shake or vibrate due to the shift of the center of gravity or imbalance caused by uneven winding of the cable, thereby improving the working stability and reliability of the cable reel.

[0014] The inner ring frame is connected with the fixed shaft through the rolling bearing. The contact fitting surface of the outer ring frame and the inner ring frame is a smooth curved surface. The cable is a flexible cable. The flexible cable can easily adapt to the winding and releasing actions of the outer ring frame, and can maintain good electrical and mechanical properties whether in a larger bending radius or a smaller bending radius. When the outer ring frame rotates around the inner ring frame, the smaller friction means that the rotation is smoother, and the required driving force is smaller, thereby improving the rotation efficiency of the cable reel, reducing energy loss, reducing heat and wear caused by friction, and prolonging the service life of the outer ring frame and the inner ring frame.

[0015] The outlet cable organizer comprises at least one guide outlet, and the cable passes through the guide outlet to enter or exit the outer ring frame.

[0016] The annular structure surface at the bottom of the power terminal is provided with a conductive coating to enhance the conductivity and wear resistance. The inner ring frame is provided with a positioning groove for positioning the power terminal, and the power terminal is fixedly installed in the positioning groove.

[0017] The double-ring frame type cable reel based on the rolling bearing and the power terminal still maintains stability during bidirectional pulling of the cable.

[0018] The above technical scheme can obtain the following beneficial effects:

[0019] Compared with the prior art, the present application has the following advantages and positive effects:

[0020] The application provides a double-ring frame type cable winder based on rolling bearings and power connection terminals, adopts deep groove ball bearings as the rolling bearings, compared with the simple rotating connection mode in the traditional winder, the deep groove ball bearings can bear radial and certain axial loads, can disperse and bear the generated radial force and axial force when the cable is pulled in two directions, reduces the shaking and deviation between the inner ring and the outer ring, and significantly improves the stability of the winder during the two-way pulling process.

[0021] The winder provided by the application is provided with an outlet cable binder, the winding efficiency of the cable is improved, the cable is prevented from being pressed and worn due to winding disorder, the service life of the cable is effectively prolonged, and the overall appearance of the winder is more regular and orderly.

[0022] The inner ring frame is integrated with the power connection terminal, and the annular structure surface at the bottom of the power connection terminal is provided with a conductive coating, so that the conductivity and wear resistance are enhanced, and the cable and the power connection terminal are ensured to be in close contact and stable power supply during mutual sliding.

[0023] The inner ring frame is connected with the fixed shaft through the rolling bearing, and the connection mode provides stable support and accurate rotating guide for the winder, ensures the structural stability and smooth rotation of the winder during the working process, and reduces the failure probability caused by unstable connection.

[0024] The cable of the application adopts a flexible cable, and the contact surface of the outer ring frame and the inner ring frame is a smooth curved surface. The flexible cable can better adapt to the winding and unwinding action of the winder and is not easy to be damaged during bending and stretching, thereby improving the use flexibility and reliability of the cable.

[0031] The application will be further explained in conjunction with the accompanying drawings and specific embodiments.

[0032] The winding device is installed on the industrial equipment at a suitable position through the fixed shaft (5), the fixed structure at both ends of the fixed shaft (5) is firmly connected with the equipment, and a stable supporting foundation is provided for the winding device. At this time, the inner ring frame (4) is rotationally connected with the fixed shaft (5) through the rolling bearing (7), and the rolling bearing (7) is a deep groove ball bearing, which can stably bear the radial load and certain axial load.

[0033] When the industrial equipment needs to be moved to different working positions, the equipment operator pulls the cable (1). The cable (1) is pulled out from the inside of the outer ring frame (3), and in the pulling process, the cable (1) passes through the guide outlet of the outlet cable organizer (2). The guide outlet of the outlet cable organizer (2) accurately guides the movement path of the cable (1), so that the cable (1) can be extended from the outer ring frame (3) in an orderly and orderly manner, avoiding the situation that the cable (1) is tangled and chaotic or excessively bent.

[0034] The embodiment includes five stages of installation, outlet, dynamic rotation, dynamic conduction and winding. In the installation stage, the winding device is installed on the equipment through the fixed shaft (5). The inner ring frame (4) is rotationally connected with the fixed shaft (5) through the rolling bearing (7). Since the rolling bearing (7) is a deep groove ball bearing, it provides stable radial support for the inner ring frame (4).

[0035] In the outlet stage, when the cable (1) is pulled, the cable is pulled out from the inside of the outer ring frame (3) and passes through the guide outlet of the outlet cable organizer (2). The outlet cable organizer (2) guides the movement path to ensure that the cable (1) extends in an orderly and orderly manner, avoiding chaos.

[0036] In the dynamic rotation stage, the outer ring frame (3) rotates around the inner ring frame (4) during the pulling process. Since the contact surfaces of the two frames are smooth curved surfaces, the rotation friction is reduced. At the same time, the deep groove ball bearing effectively disperses the radial force and axial force generated by pulling, ensuring the stability of the relative rotation between the inner ring frame (4) and the outer ring frame (3).

[0037] The dynamic conductive phase keeps the cable (1) in close contact with the ring structure at the bottom of the power terminal (6). The surface of the ring structure is coated with a conductive coating, which ensures good electrical contact during relative sliding, allowing stable current transmission.

[0038] The winding phase reverses the pulling of the cable (1) to perform the retraction action. Under the real-time guidance of the outlet wire guide (2), the cable (1) is neatly wound back inside the outer circular frame (3). The positioning slot on the inner circular frame (4) accurately fixes the power terminal (6), ensuring its stability in the entire working cycle.

[0039] In the second embodiment, the reel is installed on a fixed support near the lighting device and is securely installed through the fixed shaft (5). The power terminal (6) is connected to an external power source to provide power input for the lighting device.

[0040] When the lighting device needs to be moved to a remote work area, the cable (1) is pulled out. The cable (1) is smoothly pulled out from the outer circular frame (3) under the guidance of the outlet wire guide (2). Since the cable (1) is a flexible cable, it can easily adapt to bending and stretching during pulling without being damaged or broken.

[0041] The outer circular frame (3) rotates around the inner circular frame (4), and the deep groove ball bearing ensures stability during rotation, effectively resisting different directional forces generated by changes in the pulling direction of the cable (1). At the same time, the ring structure at the bottom of the power terminal (6) is in close contact with the cable (1), and the conductive coating ensures stable current transmission during cable (1) sliding, allowing the lighting device to emit light normally.

[0042] When the lighting work is completed, the cable (1) is retracted. At this time, the outlet wire guide (2) continues to play a role in guiding the cable (1) to be neatly wound back into the outer circular frame (3). The positioning slot on the inner circular frame (4) accurately fixes the power terminal (6), ensuring that the power terminal (6) remains stable during the reel operation and maintains good contact with the cable (1).

[0043] The above settings can also be set in other embodiments, and the scope of protection of the present invention includes but is not limited to the cases listed in this embodiment. Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore the protection scope of the present invention should be limited by the scope defined in the claims.

[0044] The above detailed description of the specific embodiments of the present application has been given to understand the purpose, technical solutions and beneficial effects of the present application. It should be understood that the above description is only a specific embodiment of the present application and is not used to limit the protection scope of the present application.
