Abstract
Description
Technical Field
[0001] This utility model relates to the field of clutch technology, and in particular to a single-input clutch and cable reel. Background Technology
[0002] A cable reel is a specialized device used for the collection, storage, and transportation of cables. It is widely used in the power, telecommunications, construction, and industrial sectors, effectively preventing cables from tangling and knotting, thus improving operational efficiency. A cable reel mainly consists of a winding reel, a motor, and a clutch. The clutch connects the motor to the winding reel, thereby controlling the on / off state of power.
[0003] A conventional clutch is a friction disc clutch, which transmits power through the contact between the friction discs. However, friction discs will inevitably wear down during long-term use, thus affecting the clutch's performance and consequently the performance of the cable reel. In addition, replacing the friction discs will increase the product's operating costs. Utility Model Content
[0004] This application provides a clutch that uses a movable insertion and positioning mechanism to achieve power transmission and disconnection, thereby avoiding the friction loss problem inherent in friction plate clutches. This application also discloses a cable reel employing the aforementioned clutch.
[0005] The first aspect of this application provides a single-input clutch, comprising:
[0006] Mounting base;
[0007] The power input shaft is rotatably connected to the mounting base;
[0008] The power output shaft is rotatably connected to the mounting base;
[0009] The driven member is fixedly connected to the power output shaft and has a limiting hole;
[0010] The active component is slidably disposed on the power output shaft and has a limiting post. When the limiting post is inserted into the limiting hole, it is in the engaged position, and when the limiting post is separated from the limiting hole, it is in the disengaged position.
[0011] An elastic element is disposed between the driving element and the power output shaft, and the elastic element is used to drive the driving element into the engagement position;
[0012] An adjustment component, connected to the mounting base, is used to control the active element to enter the engagement or disengagement position;
[0013] A limiting component is connected to the mounting base, and the limiting component is used to limit the adjustment component so that the active component is in the engaged position or the disengaged position;
[0014] An extension component is connected to the adjustment component, and the extension component is used to increase the structural length of the adjustment component.
[0015] The beneficial effects of the above embodiments are as follows: the extended component facilitates the operator's use of the clutch, the limiting component enables precise movement of the adjusting component, power is transmitted when the limiting pin is inserted into the limiting hole, and power is disconnected when the limiting pin is separated from the limiting hole, thereby avoiding the problem of easy wear of friction plates in friction plate clutches.
[0016] Based on the above embodiments, the embodiments of this application can be further improved as follows:
[0017] In one embodiment of this application: the adjusting assembly includes a clutch shaft and a rocker arm. The clutch shaft and the rocker arm are rotatably connected to the mounting base. The clutch shaft has an engaging portion and a disengaging portion. One end of the rocker arm is connected to the driving member, and the other end is connected to the clutch shaft. When the rocker arm contacts the engaging portion, the driving member and the driven member engage. When the rocker arm contacts the disengaging portion, the driving member and the driven member disengage. The beneficial effect of this step is that by rotating the clutch shaft, the rotation of the rocker arm is controlled, thereby achieving the function of engaging or disengaging the driving member and the driven member.
[0018] In one embodiment of this application: the limiting component includes: a first limiting post, a second limiting post, and a swing post. The swing post is connected to the clutch shaft. The first limiting post is located on one side of the swing post, and the second limiting post is located on the other side of the swing post. When the first limiting post contacts the swing post, the driving member is in the engaged position; when the second limiting post contacts the swing post, the driving member is in the disengaged position. The beneficial effect of this step is that by limiting the swing post with the first and second limiting posts, the operator can easily determine whether the driving member is in the engaged or disengaged position, thereby improving the ease of use of the product.
[0019] In one embodiment of this application: the extension assembly includes an extension rod and a knob, the extension rod being connected to one end of the clutch shaft, and the knob being connected to the other end of the extension rod. The beneficial effect of this step is that the extension rod extends the length of the clutch shaft, and the knob facilitates rotation of the clutch shaft by the operator, thereby improving the ease of use of the product.
[0020] A second aspect of this application provides a cable reel including the aforementioned single-input clutch. Attached Figure Description

[0029] Example 1
[0030] like Figure 1-3As shown, a single-input clutch includes: a mounting base 1, a power input shaft 2, a power output shaft 3, a driven member 4, a driving member 5, an elastic member 6, an adjusting assembly 7, a limiting assembly 8, and an extension assembly 9. The power input shaft 2 is rotatably connected to the mounting base 1, and the power output shaft 3 is rotatably connected to the mounting base 1. The driven member 4 is fixedly connected to the power output shaft 3 and has a limiting hole 401. The driving member 5 is slidably disposed on the power output shaft 3 and has a limiting post 501. When the limiting post 501 is inserted into the limiting hole 401, it is in the engaged position. The limiting post 501 and the limiting... When hole 401 is separated, it is in the separated position. The elastic element 6 is disposed between the active element 5 and the power output shaft 3. The elastic element 6 is used to drive the active element 5 into the engaged position. The adjusting component 7 is connected to the mounting base 1. The adjusting component 7 is used to control the active element 5 to enter the engaged or separated position. The limiting component 8 is connected to the mounting base 1. The limiting component 8 is used to limit the adjusting component 7 so that the active element 5 is in the engaged or separated position. The extension component 9 is connected to the adjusting component 7. The extension component 9 is used to increase the structural length of the adjusting component 7.
[0031] Specifically, such as Figure 1 As shown, the mounting base 1 is a cuboid structure. The bottom of the mounting base 1 is a base plate, which is bolted to the cable winding reel. The top of the mounting base 1 is a top plate. In order to show the internal structure of the mounting base 1, the top plate structure is omitted in the attached figure.
[0032] Specifically, such as Figure 1 , 2 As shown, the power input shaft 2 is arranged in the transverse direction. The power input shaft 2 is rotatably connected to the mounting base 1 through the bearing seat. One end of the power input shaft 2 extends to the outside of the mounting base 1 and is used to connect to the motor main shaft. The other end of the power input shaft 2 extends into the mounting base 1.
[0033] Specifically, such as Figure 2 As shown, the power output shaft 3 and the power input shaft 2 are coaxially arranged. The power output shaft 3 is rotatably connected to the other side of the mounting base 1 through a bearing seat. One end of the power output shaft 3 extends to the outside of the mounting base 1 and is used to connect components such as the winding reel. The other end of the power output shaft 3 extends into the mounting base 1 and has a gap between it and the power input shaft 2.
[0034] Specifically, such as Figure 3As shown, both the driving member 5 and the driven member 4 are disc-shaped structures. The driving member 5 has a guide hole along its axis, and the wall of the guide hole is provided with a protrusion. The power input shaft 2 is slidably inserted into the guide hole, and its outer surface is provided with a guide groove corresponding to the protrusion. The protrusion is slidably inserted into the guide groove. The protrusion guides the driving member 5 to rotate synchronously with the power output shaft 3 and can move along the axial direction of the power input shaft 2. The driven member 4 has a gap with the driving member 5 and is fixedly connected to the power output shaft 3. There are multiple limiting posts 501, which are evenly distributed on the same circumference with the axis of the power input shaft 2 as the center line. The limiting holes 401 correspond one-to-one with the limiting posts 501. The limiting holes 401 are arc holes, and the arc length of the limiting holes 401 is greater than the diameter of the limiting posts 501, so as to facilitate the insertion of the limiting posts 501 into the limiting holes 401.
[0035] Specifically, such as Figure 2 , 3 As shown, the adjustment assembly 7 includes a clutch shaft 701 and a rocker arm 702. The clutch shaft 701 and the rocker arm 702 are rotatably connected to the mounting base 1. The clutch shaft 701 has a connecting part 703 and a separating part 704. One end of the rocker arm 702 is connected to the driving member 5 and the other end is connected to the clutch shaft 701. When the rocker arm 702 contacts the connecting part 703, the driving member 5 engages with the driven member 4. When the rocker arm 702 contacts the separating part 704, the driving member 5 separates from the driven member 4.
[0036] Specifically, such as Figure 3 As shown, the adjustment assembly 7 also includes a rotating component 705, which is mounted on the end of the rocker arm 702. The rotating component 705 rolls in contact with the end face of the driving component 5 toward the driven component 4. The rotating component 705 has a disc-shaped structure. By rotating the component 705, the friction between it and the driving component 5 is reduced, thereby improving the smoothness of the movement of the entire device.
[0037] Specifically, such as Figure 3 As shown, the clutch shaft 701 is a cylindrical structure. The end of the clutch shaft has a notch arranged radially. The bottom surface of the notch is the engagement part 703, and the outer arc surface adjacent to the notch is the separation part 704. When the outer arc surface of the clutch shaft contacts the end of the rocker arm 702, the other end of the rocker arm 702 is limited, causing the limiting post 501 to separate from the limiting hole 401. When the clutch shaft rotates to the notch and moves to the end of the rocker arm 702, the end of the rocker arm 702 enters the notch and is limited by contact with the rocker arm 702 through the bottom surface of the notch. At the same time, the elastic member 6 pushes the other end of the rocker arm 702 to rotate, and the limiting post 501 enters the limiting hole 401. The driving member 5 and the driven member 4 are engaged.
[0038] Specifically, such as Figure 2As shown, the limiting component 8 includes: a first limiting post 801, a second limiting post 802, and a swing post 803. The swing post 803 is connected to the clutch shaft 701. The first limiting post 801 is located on one side of the swing post 803, and the second limiting post 802 is located on the other side of the swing post 803. When the first limiting post 801 contacts the swing post 803, the driving member 5 is in the engaged position; when the second limiting post 802 contacts the swing post 803, the driving member 5 is in the disengaged position. By limiting the swing post 803 with the first limiting post 801 and the second limiting post 802, the operator can easily know whether the driving member 5 is in the engaged or disengaged position, thereby improving the ease of use of the product.
[0039] Specifically, such as Figure 4 As shown, the extension assembly 9 includes an extension rod 901 and a knob 902. The extension rod 901 is connected to one end of the clutch shaft 701, and the knob 902 is connected to the other end of the extension rod 901. One end of the extension rod 901 is inserted into the outer end of the clutch shaft 701 and locked with bolts. The extension rod 901 is rotatably inserted into the mounting hole of the cable reel frame. The extension rod 901 extends the length of the clutch shaft 701, and the knob 902 facilitates the operator's rotation of the clutch shaft 701, thereby improving the ease of use of the product.
[0040] When using this type of single-input clutch, rotating the knob 902 causes the swing column 803 to contact the first limiting post 801. At this time, the end of the swing rod 702 enters the recess, and the driving member 5 engages with the driven member 4 under the push of the elastic member 6. Power is input through the power input shaft 2 and output through the power output shaft 3. Rotating the knob 902 causes the swing column 803 to contact the second limiting post 802. At this time, the end of the swing rod 702 moves out of the recess and contacts the separation part 704. The other end of the swing rod 702 rotates and pushes the driving member 5 to separate from the driven member 4, thereby disconnecting the power and the power output shaft 3 has no power output.
[0041] Example 2
[0042] A type of cable reel, such as Figure 4 As shown, it includes the single-input clutch disclosed in Embodiment 1.
[0043] Specifically, the cable reel also includes: a frame 10, a winding reel 11, a rotating shaft, a motor, and a transmission mechanism. There are two winding reels 11, which are rotatably connected to the frame 10 via rotating shafts. The winding reels 11 are used to wind cables. Each rotating shaft is connected to a single-input clutch, specifically to the power output shaft 3 via a coupling. The extension rod 901 of the clutch is rotatably inserted into the mounting hole of the frame 10, thereby solving the technical problem of inconvenience for operators. The motor is mounted on the frame 10, and the motor output shaft is connected to the power input shaft 2 via a transmission mechanism. The transmission mechanism adopts chain drive. The main shaft of the motor is equipped with a drive sprocket. The power input shaft 2 of the lower single-input clutch is equipped with two driven sprockets, and the power input shaft of the upper single-input clutch is equipped with one driven sprocket. The upper driven sprocket and the lower driven sprocket are driven by a chain. The other lower driven sprocket and the drive sprocket are driven by another chain. The two chains are tensioned by a tensioning sprocket rotatably mounted on the frame 10.
