Description

Technical Field

[0001] This utility model belongs to the field of storage tools technology, and relates to a cord reel. Background Technology

[0002] A cord reel can easily wind up hoses, ropes, and cables, preventing them from getting tangled and messy after use. After use, the cord can be retracted into the reel, extending its lifespan, preventing damage from exposure, and making it easy to organize and store.

[0003] A typical cable reel generally includes a housing and a rotating fork located inside the housing. The hose or cable is inserted into the housing and passes through the fork. By rotating the fork, the hose or cable rotates, causing the cable to wind around the fork and gradually be drawn into the housing.

[0004] However, this type of cable reel has the following disadvantages: 1. The casing cannot be opened, making it very troublesome to thread the cable. If the cable is relatively soft, it is difficult to thread the cable through the casing. 2. After the cable is wound, if the exposed end of the cable is accidentally pulled, the wound cable will be pulled out of the casing, and the cable will easily come loose. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems with existing cable reels by proposing a design where the housing can be opened for easy cable unwinding and can be locked after reeling to prevent accidental pulling.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A cable reel includes a housing and a fork rotatably disposed within the housing. The housing further comprises a cable winding assembly rotatably disposed on the housing and capable of moving up and down relative to the housing. Pressing the cable winding assembly downwards locks it in place with the fork. Rotating the cable winding assembly causes the fork to rotate unidirectionally for cable winding. Pulling the cable winding assembly upwards separates it from the fork, allowing the fork to rotate freely relative to the housing for cable unwinding. The housing includes a base and an outer cover, with the fork and cable winding assembly disposed on the base, and the outer cover hinged to the base.

[0008] In the aforementioned type of cable reel, the cable reel assembly includes a top cover and a dial mounted on the top cover. The dial is provided with several pawls, and a recessed hole is provided on the base. A ring of ratchet teeth is provided on the inner wall of the recessed hole. The pawls are inserted into the grooves of the ratchet teeth, and the dial can rotate unidirectionally relative to the base.

[0009] In the aforementioned type of reel, one end of the pawl is connected to the top cover via a slender connecting arm. When the dial rotates relative to the base, the pawl passes over the ratchet teeth and slides along the back of the ratchet teeth. The connecting arm undergoes elastic deformation, providing the pawl with a deformable space for movement.

[0010] In the aforementioned type of cable reel, a locking structure is provided between the dial and the fork. When the cable reel assembly descends relative to the base, the dial and the fork engage to prevent the cable reel assembly from coming off upwards.

[0011] In the aforementioned type of cable reel, the snap-fit ​​structure includes a limiting block fixed on the shift fork and a limiting retaining ring fixed on the shift dial. The limiting block has a protrusion, and one side of the limiting retaining ring has a guide slope. When the cable reel assembly descends relative to the base, the guide slope abuts against the protrusion, and the limiting retaining ring is pressed down and passes over the protrusion before being blocked by the protrusion. When the cable reel assembly rises relative to the base, the limiting retaining ring is pressed up and passes over the protrusion before separating from the limiting block.

[0012] In the aforementioned type of cable reel, a plug-in structure is provided between the dial and the fork. When the cable reel assembly descends relative to the base, the dial and the fork are plugged in to drive the fork to rotate synchronously.

[0013] In the aforementioned cable reel, the plug-in structure includes an upper inclined block fixed on a dial and a lower inclined block fixed on a fork. Several upper inclined blocks are evenly spaced along the circumference of the dial, and several lower inclined blocks are evenly spaced along the circumference of the fork. When the cable reel assembly descends relative to the base, the upper inclined block inserts downward into the gap between two lower inclined blocks, and the backs of the upper and lower inclined blocks abut against each other, allowing the dial to drive the fork to rotate. When the cable reel assembly rises relative to the base, the inclined surfaces of the upper and lower inclined blocks abut against each other and move relative to each other along the inclined surfaces until they separate.

[0014] In the aforementioned type of cable reel, the base and the outer cover are fastened together. The base is provided with a barb, and the outer cover is provided with a slot that can be fastened to the barb. Both sides of the barb are provided with clearance notches, which provide clearance space for the barb to be deformed for fastening.

[0015] In the above-mentioned type of reel, the top cover and the dial are fastened together. The top cover is provided with several hooks. The dial presses against the top cover. After the dial is squeezed and passes over each hook, it can be blocked by the hook to prevent the dial from coming off relative to the top cover. The dial is also provided with several protrusions. Each hook has a corresponding protrusion on its left and right sides to restrict the dial from rotating relative to the top cover.

[0016] In the above-mentioned type of reel, the base and the fork are fastened together. The base is provided with several hooks. The fork presses against the base. After the fork is squeezed and passes over each hook, it can be blocked by the hook, which is used to limit the fork from coming off the base and to allow it to rotate relative to the base.

[0017] In one of the aforementioned reels, the top cover is also provided with an indicator arrow, the direction of which is the direction of the reel rotation.

[0018] In the aforementioned type of cable reel, the outer wall of the top cover is further provided with several grooves, which are spaced apart along the circumference of the top cover. These grooves are used to increase the friction of the top cover during rotation, preventing hand slippage during rotation.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The shell is designed in two parts, and the outer cover can rotate relative to the base. The outer cover can be opened and fastened, which is convenient for installing wires or ropes.

[0021] 2. After the line is inserted, press the top cover. The cooperation of the limit block and the limit retaining ring will prevent the top cover from coming off upwards. Due to the cooperation of the upper and lower helical teeth, the top cover will drive the shift fork to rotate to retract the line. At this time, due to the cooperation of the pawl and the ratchet, the top cover can only rotate in one direction to prevent the line from coming loose.

[0022] 3. When it is time to feed the line, pull up the top cover, the limit block and the limit retaining ring will separate, the upper and lower helical teeth will separate, the pawl and the ratchet will separate, and the shift fork can rotate freely to feed the line;

[0023] 4. The top cover and dial, base and shift fork are all fixed by snap-fit, requiring no other fasteners, making installation simple, convenient and quick. Attached Figure Description

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] like Figure 1 As shown, the present invention provides a cable reel, comprising a housing and a fork 3 rotatably disposed within the housing. The housing also has a cable winding assembly, which is rotatably disposed on the housing and can move up and down relative to the housing. Pressing the cable winding assembly downwards locks it in place with the fork 3. Rotating the cable winding assembly causes the fork 3 to rotate unidirectionally to wind up the cable. Pulling the cable winding assembly upwards separates it from the fork 3, allowing the fork 3 to rotate freely relative to the housing to unwind the cable.

[0036] like Figure 2 As shown, the housing includes a base 1 and an outer cover 2. A fork 3 and a cable winding assembly are mounted on the base 1, and the outer cover 2 is hinged to the base 1. By designing the housing into two parts, and allowing the outer cover 2 to rotate relative to the base 1, the outer cover 2 can be opened and fastened, facilitating the installation of cables, ropes, or hoses.

[0037] like Figure 3 and Figure 4 As shown, the winding assembly includes a top cover 4 and a dial 5 mounted on the top cover 4. The dial 5 has several pawls 6, and a recessed hole is formed on the base 1. A ring of ratchet teeth 7 is provided on the inner wall of the recessed hole. The pawls 6 are inserted into the grooves of the ratchet teeth 7. The dial 5 can rotate unidirectionally relative to the base 1. One end of the pawl 6 is connected to the top cover 4 through a slender connecting arm 8. When the dial 5 rotates relative to the base 1, the pawl 6 passes over the ratchet teeth 7 and slides along the back of the ratchet teeth 7. The connecting arm 8 undergoes elastic deformation, providing deformation space for the pawl 6 to move.

[0038] like Figure 6 and Figure 7As shown, a locking structure is provided between the dial 5 and the fork 3. When the winding assembly descends relative to the base 1, the dial 5 and the fork 3 engage to prevent the winding assembly from disengaging upwards. The locking structure includes a limiting block 9 fixed to the fork 3 and a limiting retaining ring 10 fixed to the dial 5. The limiting block 9 has a protrusion 11, and one side of the limiting retaining ring 10 has a guide slope 12. When the winding assembly descends relative to the base 1, as... Figure 6 As shown, the guide ramp 12 abuts against the protrusion 11, and the limiting retaining ring 10, after being pressed and pushed downward past the protrusion 11, is blocked by the protrusion 11; when the winding assembly is raised relative to the base 1, as... Figure 7 As shown, after the limiting ring 10 is squeezed and moves upward past the protrusion 11, it separates from the limiting block 9.

[0039] like Figure 8 and Figure 9 As shown, a plug-in structure is also provided between the dial 5 and the fork 3. When the cable winding assembly descends relative to the base 1, the dial 5 and the fork 3 plug into each other to drive the fork 3 to rotate synchronously. The plug-in structure includes an upper inclined block 13 fixed on the dial 5 and a lower inclined block 14 fixed on the fork 3. Several upper inclined blocks 13 are evenly spaced along the circumference of the dial 5, and several lower inclined blocks 14 are evenly spaced along the circumference of the fork 3. When the cable winding assembly descends relative to the base 1, as... Figure 8 As shown, the upper inclined block 13 is inserted downward into the gap between the two lower inclined blocks 14, with the backs of the upper inclined block 13 and the lower inclined blocks 14 abutting against each other. The dial 5 can drive the fork 3 to rotate. When the winding assembly is raised relative to the base 1, as shown... Figure 9 As shown, the inclined surfaces of the upper inclined block 13 and the lower inclined block 14 abut against each other and move relative to each other along the inclined surfaces until they separate.

[0040] like Figure 2 As shown, the base 1 and the outer cover 2 are fastened together. The base 1 has a barb 15, and the outer cover 2 has a corresponding slot that can be engaged with the barb 15. Both sides of the barb 15 have clearance notches 16, which provide clearance space for the barb 15 to deform and engage. The top cover 4 also has an indicator arrow 20, the direction of which indicates the direction of line winding. The outer wall of the top cover 4 also has several grooves 21, which are spaced apart around the circumference of the top cover 4. These grooves increase the friction of the top cover 4 during rotation, preventing hand slippage.

[0041] The outer cover 2 can be fixed to the wall or table with adhesive for easy storage and organization.

[0042] like Figure 4As shown, the top cover 4 and the dial 5 are fastened together. The top cover 4 is provided with several hooks 17. The dial 5 presses against the top cover 4. After the dial 5 is squeezed and passes through each hook 17, it can be blocked by the hook 17, which is used to limit the dial 5 from coming off relative to the top cover 4. The dial 5 is also provided with several protrusions 18. Each hook 17 has a corresponding protrusion 18 on its left and right sides, which is used to limit the dial 5 from rotating relative to the top cover 4.

[0043] like Figure 5 As shown, the base 1 and the fork 3 are fastened together. The base 1 is provided with several hooks 19. The fork 3 presses against the base 1. After the fork 3 is squeezed and passes through each hook 19, it can be blocked by the hook 19, which is used to limit the fork 3 from coming off relative to the base 1 and to allow it to rotate relative to the base 1.
