As shown in FIGS. 1 to 6, the cable reel for camping according to the embodiment of the present invention includes a base 10, a spool 20, and a swivel 30.

The base 10 is a base for firmly installing on the ground or the floor, and is made of cast iron or steel plate, so that it does not rotate on the ground and supports the spool 20 and the swivel 30 in a horizontal state. A large number of spikes are formed at regular intervals on all four edges.

In addition, the base 10 at the position facing the stop hole 36 of the rotating table 30 is restrained so that the rotation of the rotating table 20 around the rotating shaft 21 of the rotating table stops at a predetermined angle step by step and the free rotation thereof. The ball plunger 13, which is elastically engaged by the spring force of the spring, is mounted to the stop holes 36 of the second support 34 to limit the pressure.

Here, the ball plunger 13 has a ball (or pin) embedded at one end of the cylinder so as to cause a stopping action at a fixed position, that is, the stop hole 36 of the swivel, and a spring supporting the ball is built in the cylinder. When a force is applied from an external counterpart, the structure can be adopted to enter the cylinder and return to its original state by spring elasticity.

In addition, peg holes 12 are formed at all four edges of the base 10 so as to drive separate pegs to be firmly fixed to the ground.

The spool 20 is for winding or unwinding the cable C. The spool 20 has a cylindrical shape having a predetermined diameter so that the cable C can be wound. The spool 20 has one side in the longitudinal direction of the rotating shaft 21. It is rotatably provided in the up-down direction from the upper side of the base 10 while being supported by).

The ratchet wheel 22 which is rotated at the same time as the spool 20 is fixed to one end of the rotational shaft 21 in the longitudinal direction, and when the spool 20 is rotated on the swivel 30 corresponding to the ratchet wheel 22. A stopper 23 is provided which selectively interferes with the ratchet wheel 22 and causes interference so that the spool 20 is rotated only in a direction about the rotation axis 21 thereof.

That is, the stopper 23 is mounted on the first support 32 of the swivel to prevent the rotating shaft 21 of the spool from being rotated by the loosening action of the spiral spring 25.

In addition, as shown in FIG. 4, the swivel 30 is equipped with a return spring 24 for keeping the stopper 23 bite with the ratchet wheel 22.

That is, the return spring 24 has a function and role of providing a resilient restoring force for the stopper 23 to quickly return to maintain the original position and state of the bite with the ratchet wheel 22, one end of which stopper It is fixed to 23, and the other (opposite) end part is being fixed to the 1st support 32. As shown in FIG.

Here, the return spring 24 is made of stainless steel, but preferably adopts a torsion spring that uses a torsional displacement generated when the stopper 23 is rotated. However, the return spring 24 is not limited thereto. something to do.

For example, applying a pulling force increases its length, and releasing it returns to its original length, ie generating a tensile force in a direction opposite to an externally acting force to quickly return to its original position or state. Tensile coil springs can be employed.

And as shown in Figure 5 inside the spool 20 is a spiral spring that provides an elastic restoring force to rotate in the direction of winding the cable by accumulating elastic energy while the rotary shaft 21 rotates in the direction of unwinding the cable (25) is built in.

That is, the spiral spring 25 is provided in a shape wound around the outer circumference of the rotating shaft 21 in the spool 20 to provide an elastic restoring force, ie withstand torque, which rotates the rotating shaft 21 of the spool during the compression operation. And the rolled inner end of the spiral spring 25 is fixed to the rotation shaft 21 of the spool, and the outer end is fixed to the inner side of the spool 20.

The spiral spring 25 accumulates elastic energy while being gradually compressed in its winding direction as the rotating shaft 21 of the spool rotates, and when the winding force is removed, the spiral spring 25 is released to its original state by an elastic action. 21) the reel rotates in the opposite direction.

Here, the spiral spring 25 may be mounted inside the spool 20 in a form protected by a separate case or disc, of course.

On the other hand, the spool 20 is provided with a temperature sensor 26 for sensing the temperature of the cable (C) wound around the outer side, one side display the temperature value to be transmitted from the temperature sensor 26 in real time The temperature display part 27 is provided.

That is, overheating occurs due to an electric load or an overcurrent flows without an electric current flowing normally in the cable C wound on the spool 20, and the temperature sensor 26 detects it and displays it in real time on the temperature display part 27. Therefore, it is possible to immediately detect whether an abnormal current flows or overheating of the cable, and prevent electric safety accidents such as a burnout or fire of the cable.

Here, the temperature sensor 26 may be made of a bimetal that detects when the cable C wound on the spool 20 is overheated above a predetermined temperature and automatically short-circuits the current flowing through the cable C.

The swivel table 30 supports the spool 20 on the upper side of the base 10 so as to be rotatably supported in the vertical direction, and the spool 20 can be rotated at a predetermined angle in the horizontal direction when the cable C is unwound or wound. It is to be mounted on the base 10 so as to be rotated step by step within a certain angle range around the rotary shaft 31 to limit its free rotation.

The swivel table 30 is vertically formed, and is formed horizontally at the lower end of the first support 32 and the first support 32 in which a shaft hole 33 is formed to support the rotating shaft 21 of the spool. It consists of a second support (34).

In addition, the second support 34 is equipped with a bearing 35 for smoothing the rotational movement while supporting the rotating shaft 21 of the rotating table, the rotating table 20 is within a constant angle range around the rotating shaft 21. A plurality of stop holes 36 are formed at radially constant intervals along the angle of the movable range at the rotation center of the swivel table 20 so as to rotate in stages.

That is, by the intermittent interference between the ball plunger 13 and the stop holes 36 of the second support, the swivel table 30 can feel a click feeling at a certain angle when the swivel table 30 rotates. ) Can be prevented from rotating too fast at once by the external force to pull the cable strongly to prevent the swivel 30 to freely rotate or wiggle.

In addition, a handle 38 is provided on the upper side of the first support 32 of the swivel table 30 to facilitate gripping and the like at the time of carrying and transporting.

The handle 38 may prevent the cable from tangling when the cable C is wound or unwound on the spool 20 and may be used as a guide for smooth guidance.

That is, the handle 38 is made of a structure that is freely rotated when receiving an external force to reduce the friction force can be wound or unwind the cable more quickly and conveniently.

On the other hand, the outer side of the swivel 30 is equipped with an outlet 40 that receives power through the cable (C). And the outlet 40 is provided with a power amount display unit 41 for displaying the amount of power used in real time, and when a large amount of current flows, the breaker for disconnecting the conductor to block the current does not flow, preventing the risk of electric shock due to short circuit 42 is built in to allow for manual opening and closing of the track and returning after automatic shutoff.

Here, a plug for connecting to an external power source may be provided at the outer end of the cable C in the longitudinal direction, that is, the end opposite to the end connected to the outlet 40.

Referring to the main operation and principle of the cable reel for camping according to the embodiment of the present invention configured as described above are as follows.

First, if the user presses the base 10 with the foot or presses the base 10 in a state in which the base 10 is in close contact with the ground or the floor, the spikes 11 protruding from all four corners are embedded in the ground to maintain a solid installation state. By doing so, the spool 20 and the swivel 30 can be stably supported. As a result, the spool 20 can wind or unwind the cable C stably without shaking.

In this state, the spool 20 can be freely rotated in its disengaging direction and easily released by only the force for pulling the cable C, but the ratchet wheel 22 and the stopper 23 which are integrally fixed to the rotation shaft 21. The rotation of the cable C is prevented in the direction in which the cable C is wound by the biting action of the cable C, so that the cable C can be kept in a fixed length.

At the same time, the spiral spring 25 is gradually compressed in the winding direction as the rotating shaft 21 of the spool rotates to maintain a state in which elastic energy is accumulated.

Thereafter, when the cable C is to be wound around the spool 20, when the cable C is pulled over a predetermined length, the restraint state of the ratchet wheel 22 by the stopper 23 is temporarily released. It is possible to rotate the rotary shaft 21 of the spool in the opposite direction while the coil spring is released to its original state by the elastic action of the spiral spring 25, and as a result, the cable C can be wound around the spool 20 semi-automatically. .

The stopper 23 is returned to its original position by the elastic restoring force of the return spring 24 which is deformed in this process, and is switched to the bite with the ratchet wheel 22.

In addition, if the external force to pull the cable (C) is not in line with the vertical direction of rotation of the spool 20, the swivel table 30 supporting the spool 20 at a predetermined angle in the left and right directions by the force to pull the cable (C) Since the rotation direction of the pulling and the vertical rotation direction of the spool 20 naturally match, the cable C can be wound more uniformly and easily on the spool 20.

Moreover, as shown in FIG. 6, the ball of the ball plunger 13 is selectively inserted into the stop hole 36 of the swivel 30, so that the rotation of the swivel 20 stops at a predetermined angle step by step, and its free rotation. By limiting the vertical direction of rotation of the spool 20 to keep the cable (C) in line with the winding or unwinding direction, so that the cable can be wound or unwound easily and naturally in the spool 20, regardless of the specific direction, This can prevent the cable C from twisting or twisting.

On the other hand, the present invention is not limited by the above-described embodiments and the accompanying drawings, and various modifications and applications that are not illustrated within the scope not departing from the technical spirit of the present invention, as well as of each component It is apparent to those skilled in the art that the present invention may be widely applied by changing to other embodiments equivalent to substitution.
