Abstract

The present invention relates to a depth finder comprising: a buoy having an installation space; a rotary roller coupled to the installation space of the buoy to be rotated; a depth measurement wire wound on the rotary roller having one end positioned on the water and the other end fallen down to a riverbed and a lakebed to measure a depth; a weight coupled to the other end of the depth measurement wire to draw downward the other end of the depth measurement wire to the underwater bed; a ratchet gear coupled to one side of the rotary roller to control the rotary roller to be rotated in a specific direction; and an operation lever engaged with the ratchet gear to rotate the ratchet gear in a specific direction. If the buoy floats on the river or the lake to be measured, the depth measurement wire is pulled downward to draw out the weight until the weight free falls and reaches to the bed. When the weight reaches to the bed and stops falling, the depth measurement wire is pulled upward. Since the rotary roller is not rotated backward by the engagement of the ratchet gear and the operation lever, a length between the buoy and the weight constantly maintains and the buoy, the depth measurement wire, and the weight simultaneously rise upward. Therefore, the depth is simply measured by floating the buoy at a part to be measured and rising upward the buoy after a predetermined time, thereby simply and accurately measuring the depth.

Depth finder

The present invention relates to a water depth measuring apparatus, and more particularly, to a water depth measuring apparatus capable of accurately and automatically measuring a water depth of an object to be measured easily and easily, and a water depth measuring apparatus ≪ / RTI >

The factors that make life exist on Earth are the critical elements of light, air, soil, heat, light and water, which are irreplaceable factors. Among these, water is a tangible and quantitative resource that can be energized as tangible as other resources such as petroleum, land, and minerals, and it also has intangible value of non - quantifiable value.

For example, the clear water of the lake gives life to human life, and the water of a quiet flowing river not only provides a place for life to many living creatures living in the water, but also serves as a means of transportation for human life . The value of water as a resource is different from other resources in terms of tangible and intangible. Since water resources are uncertain and circulating infinite resources, other resources can detect the limitations of development by measuring reserves, but in the case of water resources, most of the water resources are derived from precipitation from the basin (basin) The precipitation itself is not constant every year, and the amount of water as an available resource is uncertain.

However, most of the available resources are reduced by use, but there is no limit in the case of water resources because they can be obtained from the watershed with almost the same amount every year. Therefore, it can be said that it is an infinite resource, and the water used for hydroelectric power generation in the upper stream can be used as agriculture, industry, and living water in the downstream, and the abandoned wastewater penetrates into the underground and becomes the source of groundwater. .

Such water is an essential resource that is the source of all living things. It is not only essential for the growth of living things, but also an important raw material for the production of general industrial products.

The systematic and efficient management and operation of water with such a value makes it clear that it is fundamental to the basic national economy and life development of the country. Therefore, countries around the world manage water resources in their own countries and operate them appropriately and efficiently.

Therefore, by accurately measuring the depth of water in nails, reservoirs, lakes, rivers, rivers, groundwater, and seas, the water depth can be accurately measured and used as basic data for more systematic and efficient management and operation of water resources, In addition, various depth measurement methods have been developed and used to actively utilize the data for various purposes.

One of the conventional depth measuring methods is a rod method.

To measure the water depth with a bar, the operator moves the bar to the place where the water depth is to be measured, and then vertically moves the bar so that the bottom of the bar touches the bottom. Next, measure the depth by lifting the rod in water and measuring the length from the bottom of the rod to the part wet with water.

However, such a method of measuring the depth of water is very inconvenient and has a problem that reliability is lowered due to a large measurement error. In other words, it is inconvenient for an operator to carry a long rod to a depth measuring position and to travel using a boat or other means, and it is not easy to accurately measure the rod by vertically lowering it to the bottom of an invisible river or lake.

In addition, since the bottom surface of a river bed or a lake bottom is not uniform, it is necessary to measure the water depth several times while moving the place and obtain an average value.

However, it has been difficult to measure the depth of a shallower area after measuring the depth of the water by the conventional measurement method described above. In other words, the bar that measures the depth of the deep water is in the state of water, and when the depth of the shallow water is measured by such a bar, the mark on the bar is not properly displayed and it is difficult to read the depth accurately .

On the other hand, devices for accurately measuring water depth have been developed and used. Among them, there is a water depth measuring device using a laser beam of Korean Patent No. 213599, which is registered as a domestic application.

In this water depth measuring apparatus, a pipe inserted so that the light reflecting sphere can move along the water surface of the reservoir is installed at a predetermined angle in the reservoir, and the laser beam is emitted from the laser beam generator toward the sphere, And detects the arrival time of the reflected laser beam to measure the depth of water.

Here, a hollow pipe to which a laser beam generator is connected, and a secondary sphere inserted into the pipe movably and having a surface coated with a light reflecting material are included.

However, such a conventional depth measuring apparatus using a laser beam has some problems.

First, since a pipe having a proper length and diameter to be installed to the measurement target site, that is, the bottom floor of the reservoir, must be prepared at the time of measuring the depth of water, there is a drawback that installation easiness, transportation and portability are poor.

Secondly, expensive devices such as a laser beam generator, a measurement reading and a laser beam sensor must be provided, which increases the initial purchase cost.

Third, a single pipe with a length corresponding to a length of 50 to 100 m, which has a diameter corresponding to the length, must be equipped with an additional device such as a laser beam generator, a measurement reading and a laser beam sensor, Or a plurality of pipes which are divided into one to two meters so that they can be easily assembled and assembled. Therefore, it is not possible to easily measure the depth of the water by simply moving the water. In order to measure the water depth, There are drawbacks that are costly.

Fourth, the position of the measurement object can not be easily changed. This is because it is impossible to move when the pipe is assembled. Therefore, there is a small inconvenience such as measuring the depth by moving after disassembling and then reassembling. Therefore, the product can not satisfy various needs of customers with its merchantability and reliability, There are limitations on the measurement object in accordance with the present invention.

Korean Patent Registration No. 10-213599

SUMMARY OF THE INVENTION An object of the present invention is to provide a water depth measuring apparatus in which a water depth is easily measured by lifting a floating point on a water to be measured and lifting after a predetermined time elapses.

It is another object of the present invention to provide a water depth measuring apparatus which is relatively simple in construction, reduces the number of assembling operations, reduces the manufacturing cost because expensive parts are not used, and facilitates transportation and storage.

It is still another object of the present invention to provide a water depth measuring apparatus which can easily measure a water depth at a relatively remote location around a river or a lake.

It is still another object of the present invention to provide a depth measuring apparatus in which a counter shaft is rotated by a pulled-out length of a water depth measuring rod when the water depth measuring rod is pulled to a bottom surface of water by a weight,

It is still another object of the present invention to provide a depth-of-field measuring apparatus capable of simply checking a measured depth.

In order to achieve the above object, the apparatus for measuring depth of water according to the present invention comprises: A center shaft installed in the installation space of the mouthpiece; A pivoting roller coupled to rotate about a central axis; A water depth measuring line wound around the rotating roller and having one end located in the water phase and the other end located on the bottom of the river bed or lake to measure water depth; A weight attached to the other end of the depth measuring line and dragging the other end of the depth measuring line to the underwater floor; A ratchet gear installed on the central shaft and coupled to one side of the pivoting roller to rotate together with the pivoting roller and to control the pivoting roller to rotate in only one direction; An operating lever having one end mounted on a lever supporting shaft in the installation space and the other end engaged with the ratchet gear so that the ratchet gear is rotated in only one direction; And a spring installed on the lever support shaft and connected to the operation lever to elastically support the other end of the operation lever toward the ratchet gear.

Another feature of the water depth measuring apparatus of the present invention is that a counter is provided in an installation space above the rotating roller to measure a pulled-out pull-out length when the depth measuring rod is pulled to the water floor by weight; The counter includes a counter shaft that is rotated by a depth measuring line that is wound around a depth measuring line wound around a rotating roller and is pulled downward by a weight, and a counter shaft connected to the counter shaft. And a display unit for counting the rotation amount.

Another feature of the depth measuring device of the present invention is that the operation lever is connected to the lever release rope so that the operation lever is pulled upward from the ratchet gear by pulling the end portion of the operation lever engaged with the ratchet gear.

According to another feature of the apparatus for measuring water depth of the present invention, the water depth measuring line is provided with a scale so that the measured water depth can be read.

As described above, according to the present invention, as described above, the present invention is characterized in that it comprises: a swinging roller coupled to rotate in a swinging roller to be rotated in an installation space of a swinging hole; And a ratchet gear coupled to one side of the pivoting roller so as to rotate the pivoting roller only in one direction, and a ratchet gear coupled to the other end of the pivoting rod, And an operating lever engaged with the ratchet gear to rotate the ratchet gear in only one direction. Therefore, when float is placed on a river or a lake to measure water depth, the water depth is pulled out by pulling down the water depth measuring line until the floor falls down by natural dropping of weight, and when the falling is stopped by the weight added floor, At this time, the rotation roller is not rotated reversely due to the engagement of the ratchet gear and the operation lever, so that the length between the ball and the weight is kept constant while the ball, the water depth and the weight are increased at the same time. Therefore, it is very simple and accurate to measure the depth of water because the depth is measured by lifting the bulb at the site where the water depth is to be measured and lifting it after a certain time.

Since the water depth measuring apparatus of the present invention is composed of a bore, a depth measuring line, a weight, a rotating roller, a ratchet gear, and an operating lever, the configuration is relatively simple and the number of assembly work is reduced. , It can be transported and stored after winding the drawn water depth measurement line, and the water depth can be measured by the very simple operation which floats the part to be measured, so that the water depth of various parts can be measured easily and quickly.

If the depth measuring device of the present invention is used in connection with a fishing line of a fishing rod, the depth of a relatively far point can be measured even without a ship. That is, when the operator throws the water depth measuring device connected to the fishing line around the river or the lake to the river or the lake side by using the elasticity of the fishing rod, the water floats on the water surface relatively far away from the river and the water depth is measured while the weight is further lowered. You can check the depth of the water by lifting the fishing line, lifting the cuspid, weight, and depth measurement line. Therefore, it is possible to easily measure the deep water depth at a relatively remote location around rivers or lakes.

The counter shaft of the present invention includes a counter shaft that is rotated when a depth measuring line wound around a rotating roller is wound and pulled downward, and a display unit that is connected to the counter shaft and counts by the amount of rotation when the counter shaft is rotated Is provided. Therefore, when the depth measuring line is pulled to the underwater floor by the weight, the counter shaft rotates by the pulled-out length and is displayed numerically on the display unit, so that the measured depth can be easily confirmed only by the number of the display unit.

In the operating lever of the present invention, a lever releasing string is connected to pull the upper end of the operating lever engaged with the ratchet gear so that the operating lever is separated from the ratchet gear. This lever release cord is used when the water depth is measured and then the water depth measurement line is wound up to the zero point touching the bottom of the weight addition unit. That is, when the lever release line is pulled upward, the end of the operation lever and the ratchet gear are disengaged, and the ratchet gear is rotatable in the reverse direction. In this state, the water depth measurement line is wound up to the zero point reaching the lower portion of the weight addition section .

The lever release lever of the present invention is characterized in that the force pulled downward by the weight of the weight and the spring force for elastically supporting the end of the operation lever toward the ratchet gear are the same or similar, It is useful for the case where it does not fall down to the bottom. That is, when the force due to the weight of the weight and the force of the spring are the same or similar and the balance of force is maintained between them, if the buoy is placed on the water and the lever releasing rod is pulled upward, The rotatable roller and the ratchet gear are rotated by the weight of the weight, and the rotational force of the operating lever and the ratchet gear is added to the self weight of the weight, The roller and the ratchet gear are continuously rotated. Therefore, even if the buoy is floated on the water, since the water depth is measured while the weight is further lowered by pulling and releasing the lever release cord, the buoy is positioned on the water and there is a margin to correct the position of the buoy. .

In the depth measuring line of the present invention, a scale is formed so that the measured depth can be read. Therefore, it is very easy and quick to measure the depth of water because it is possible to simply check the depth by reading only the scale of the last part of the drawn length of the depth measuring line without a separate tool for measuring the length of the drawn depth measuring line.

Specific features and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings.

FIG. 1 is a schematic perspective view showing a main part of a depth measuring apparatus of the present invention, FIG. 2 is a side sectional view of FIG. 1, and FIG. 3 is a partial enlarged side sectional view of FIG.

The water depth measuring apparatus of the present invention includes an attachment 10, a central shaft 12, a rotating roller 14, a depth measuring rod 16, a weight 18, a ratchet gear 20, an operation lever 22, , And a spring (28).

The installation space 11 is formed so that a large number of parts are installed in the interior of the unit.

The center shaft 12 is provided in the installation space 11 of the auxiliary port 10 and both ends thereof are fixed to the auxiliary port 10.

The rotation roller 14 is coupled to the center shaft 12 so as to be rotated, and the water depth measurement line 16 to be described later is wound around the rotation roller 14 one turn.

The water depth measuring line 16 is wound around the rotating roller 14, one end is located in the water phase, and the other end is located on the bottom of the river bed or the lake, and the water depth is measured.

When the water depth measurement line 16 is pulled downward, the rotation roller 14 is rotated by the frictional force between the water depth measurement line 16 and the rotation roller 14. [

The weight 18 is coupled to the other end of the depth measuring rod 16 and pulls the other end of the depth measuring rod 16 down to the bottom of the water.

The ratchet gear 20 is mounted to rotate on the center shaft 12 and is fixed to one side of the rotation roller 14 so as to be rotated together with the rotation roller 14 so as to rotate the rotation roller 14 in only one direction.

That is, when the weights 18 are pulled downward by the water depth measuring rod 16 while falling down underwater, the rotating roller 14 and the ratchet gear 20 are rotated in the clockwise direction, The operation lever 22 and the ratchet gear 20 are engaged with each other and the reverse rotation is prevented when the rotation roller 14 and the ratchet gear 20 are going to rotate counterclockwise by being pulled upward.

One end of the operation lever 22 is pivotally mounted on the lever support shaft 24 in the installation space 11 and the other end is engaged with the ratchet gear 20 so that the ratchet gear 20 is rotated in only one direction.

The spring 28 is provided on the lever support shaft 24 and is connected to the operation lever 22 so that the other end of the operation lever 22 is elastically supported on the ratchet gear 20 side. These springs can be made of torsion springs.

In the depth measuring device of the present invention having such a configuration, the depth measuring line 16 is pulled downward around the pivoting roller 14 by the structure of the ratchet gear 20, the operation lever 22, and the spring 28 And is not pulled upward.

Accordingly, when the buoy 10 is floated on a river or a lake to measure the depth, the depth measuring rod 16 is pulled downward until the weight 18 falls down and touches the floor. At this time, when the depth measuring line 16 is pulled downward by the weight 18, the rotating roller 14 is rotated by the frictional force between the depth measuring line 16 and the rotating roller 14, Is rotated.

When the weights 18 touch the bottom surface and the dropping stops, the lifting roller 14 pulls up the depth measuring rod 16 upward. At this time, the rotation roller 14 is rotated by the engagement of the ratchet gear 20 and the operation lever 22 The length of the portion 10, the depth measuring line 16, and the weight 18 are simultaneously elevated while the length between the attachment 10 and the weight 18 is kept constant.

That is, when the water depth measurement line 16 is pulled upward, the rotation roller 14 tries to rotate counterclockwise, but when the operation lever 22 and the ratchet gear 20 are engaged with each other, the rotation of the ratchet gear 20 is prevented . Therefore, even if the water depth measurement line 16 is pulled upward, the rotation roller 14 and the ratchet gear 20 are not rotated in the reverse direction.

Therefore, when lifting the water depth measurement line 16, the rotation roller 14, the ratchet gear 20 and the port 10 are lifted together, so that the length of the measured depth measurement line 16 is not varied. Therefore, when the buoy (10) is floated on the site where the water depth is to be measured and lifted after a certain period of time, the water depth is simply measured, so that the water depth measurement operation is very simple and accurate.

Since the depth measuring apparatus of the present invention is composed of the crown 10, the depth measuring line 16, the weight 18, the rotating roller 14, the ratchet gear 20 and the operating lever 22, As a result, the number of assemblies is reduced, and expensive parts are not used.

In addition, according to the present invention, when the drawn water depth measuring line 16 is wound, the parts installed inside the water hole 10 and the water hole 10 are attached together, and thus the water depth measuring apparatus of the present invention can be easily carried and stored.

When the buoy (10) is raised again at the position where the water depth is to be measured after lifting the buoy (10), the water weight is measured while the weight (18) is lowered and thus the water depth at the other point can be measured by a very simple operation. The depth of water at various points can be measured easily and quickly.

When the depth measuring device of the present invention is used in connection with the fishing line 46 of the fishing rod 44, it is possible to measure the water depth at a relatively far point even without a ship.

That is, when a worker throws a water depth measuring device connected to the fishing line 46 around a river or a lake to the river or the lake side using the elasticity of the fishing rod 44, the fishing line 10 and the weight weight 18, The water depth is measured when the weight 18 falls down and the fishing line 46 is wound after the water depth is measured and the fishing line 10 and the weight 18 ), The water depth can be ascertained by raising the water depth measuring line 16.

Therefore, it is possible to easily measure the deep water depth at a relatively remote location around rivers or lakes.

FIG. 5 is a schematic exploded perspective view illustrating another embodiment of the present invention, and FIG. 6 is a side view of the installation of FIG.

The present invention is characterized in that the counter 30 is installed so as to measure the pulled-out drawn length when the water depth measuring line 16 is pulled to the bottom surface of the water by the weight 18 in the installation space 11 on the upper side of the rotation roller 14 .

The counter 30 includes a counter shaft 32 which is wound by a depth measuring line 16 passed through a rotating roller 14 and rotated by a depth measuring line 16 which is drawn down by a weight 18, And a display unit 34 connected to the counter shaft 32 and counting the rotation amount of the counter shaft 32 when the water depth measurement line 16 is drawn and the counter shaft 32 is rotated.

The second guide shaft 40 having the second guide shaft 40 and the second guide roller 42 provided with the first guide roller 38 is installed in the installation space 11 on both sides of the counter 30 have. The counterweight shaft 32 and the first guide roller 38 are sequentially passed through the weight guide 18 via the pivoting roller 14 and then the second guide roller 42, It is then placed as a prime minister.

In the present invention, when the depth measuring rod 16 is pulled to the bottom surface of the water by the weight 18, the counter shaft 32 rotates by the pulled-out length thereof and is displayed numerically on the display unit 34 It is possible to easily check the measured depth by looking only at the number of the display unit 34. [

FIG. 3 is a partially enlarged side sectional view of FIG. 2, and FIG. 4 is a partially enlarged side sectional view showing a state in which the operating lever is released.

The lever release rods 26 are provided on the operation lever 22 of the present invention so as to pull the end portion of the operation lever 22 engaged with the ratchet gear 20 upward so that the operation lever 22 is separated from the ratchet gear 20 It is connected. The lever release cord 26 is used when the water depth is measured and then the water depth sensor 16 is wound to raise the weight 18 to the zero point where the weight 18 touches the bottom of the mouth.

That is, when the lever release line 26 is pulled upward, the end of the operation lever 22 and the ratchet gear 20 are disengaged, and the ratchet gear 20 becomes rotatable in the reverse direction. In this state, So that the weight 18 can be raised to the zero point where it touches the bottom of the mouth 10.

The lever release cord 26 of the present invention is provided with a spring 28 which elastically supports the end of the operation lever 22 and the force pulled downward by the load of the weight 18, Are used for the case where the unit 10 does not drop automatically even if the unit 10 floats on the water due to the same or similar force.

That is, when the force due to the weight of the weight 18 and the force of the spring 28 are the same or similar to each other and the force balance is maintained therebetween, the buoy 10 is floated and the lever release cord 26 The rotating roller 14 and the ratchet gear 20 are rotated by the weight of the weight 18 while the end of the operating lever 22 and the ratchet gear 20 are disengaged.

The rotating force of the operating lever 22 and the ratchet gear 20 is added to the weight of the weight 18 when the rotating roller 14 and the ratchet gear 20 are once rotated, The rotating roller 14 and the ratchet gear 20 are continuously rotated until the weight 18 comes into contact with the bottom surface.

Therefore, even if the cigarette 10 is floated on the water, since the weight 18 is lowered and the depth of the cigarette 18 is measured only after the lever release cord 26 is pulled and placed, the position of the cigarette 10 Thereby, it is possible to measure the water depth at the correct point.

On the other hand, as shown in FIG. 7, a scale 48 can be formed on the depth-measuring line 16 so that the measured depth can be read.

Therefore, without reading out the length of the extracted depth measurement line 16, it is possible to easily determine the depth of the depth by simply reading the scale 48 of the last portion out of the drawn depth of the depth measurement line 16, It can be done easily and quickly.

The present invention has the following effects.

First, according to the present invention, when the buoy 10 is floated on a river or a lake to measure water depth, the water depth measuring rod 16 is pulled downward until the weight 18 falls down and reaches the floor, The rotation roller 14 is not reversely rotated due to the engagement of the ratchet gear 20 and the operation lever 22, While the length between the weight 10 and the weight 18 is kept constant, the weight 10, the depth measuring line 16 and the weight 18 are raised at the same time.

Therefore, when the buoy (10) is floated on the site to measure the water depth and lifted after a certain period of time, the water depth is simply measured, so that the water depth measurement operation is very simple and accurate.

Secondly, since the apparatus for measuring depth of water according to the present invention is composed of the claw 10, the depth measuring line 16, the weight 18, the rotating roller 14, the ratchet gear 20 and the operating lever 22, The number of assembly operations can be reduced and manufacturing cost can be reduced because expensive parts are not used.

In addition, since the water depth can be measured by winding the drawn water depth measurement line (16) and then floating the floating point (10) at another position to be measured, the water depth of various parts can be measured easily and quickly.

Thirdly, when the worker throws the water depth measuring device connected to the fishing line 46 around the riverside or the lake to the river or the lake side by using the elasticity of the fishing rod 44, the fishing port 10 floats on the waterfront relatively far away, 18 are lowered and the depth of the water is measured. After the water depth is measured, the fishing line 46 is wound to ascend the fishing port 10, the weight 18, and the water depth measuring line 16 to check the measured water depth.

Therefore, it is possible to easily measure the deep water depth at a relatively remote location around rivers or lakes.

Fourth, in the present invention, when the depth measuring rod 16 is pulled to the bottom surface of the water by the weight 18, the counter shaft 32 rotates by the drawn length of the water depth measuring rod 16 and is displayed numerically on the display unit 34 It is possible to easily check the measured depth by looking only at the number of the display unit 34. [

Fifthly, according to the present invention, when the lever release line 26 is pulled upward, the end of the operation lever 22 and the ratchet gear 20 are disengaged and the ratchet gear 20 becomes rotatable in the reverse direction. In this state, It is possible to raise the weight 18 to a zero point where the weight 18 touches the bottom of the mouth 10.

Sixth, when the balance of the force is maintained between the force of the weight 18 and the restoring force of the spring 28, the buoy 10 is floated and the lever release cord 26 is pulled upward The rotatable roller 14 and the ratchet gear 20 are rotated by the weight of the weight 18 while the end of the operation lever 22 and the ratchet gear 20 are disengaged and thereby the weight of the weight 18 The rotating force of the operating lever 22 and the ratchet gear 20 is added to the rotating roller 14 and the ratchet gear 20 until the weight 18 comes into contact with the bottom surface in spite of the elastic force of the spring 28. [ Is continuously rotated.

Therefore, the present invention changes the elastic force of the spring 28 by changing the spring 28 or changes the load of the weight 18 by replacing the weight 18, so that the elasticity of the spring 28 and the weight 18 So that the weight 18 can be lowered by pulling and releasing the lever release cord 26 even if the cigarette 10 is floated on the water. Therefore, there is room to correct the position of the plug 10 after the plug 10 is floated on the water, so that the water depth at the correct point can be measured.

Seventhly, in the water depth measuring line 16 of the present invention, a scale 48 is formed so that the measured depth can be read, and thus, without a separate tool for measuring the length of the drawn depth measuring line 16, The water depth can be easily confirmed by reading only the scale 48 of the last portion out of the length of the line 16.

On the other hand, a cover 13 is provided on the upper part of the attachment 10 to protect the parts provided in the installation space 11 of the attachment 10. [

The cover 13 may be formed of a polypropylene resin composition having excellent impact resistance against external impact or external environment. The polypropylene resin composition comprises a polypropylene random block copolymer composed of 75 to 95% by weight of an ethylene-propylene-alphaolefin random copolymer and 5 to 25% by weight of an ethylene-propylene block copolymer having an ethylene content of 20 to 50% by weight .

The polypropylene random block copolymer is preferably 75 to 95% by weight of the ethylene-propylene-alphaolefin random copolymer and 5 to 25% by weight of the ethylene-propylene block copolymer. The ethylene- When the content of the ethylene-propylene block copolymer is less than 5% by weight, the impact resistance is deteriorated. When the content of the ethylene-propylene block copolymer is more than 25% by weight, the rigidity is deteriorated do.

Wherein the ethylene-propylene-alpha olefin random copolymer comprises 0.5 to 7% by weight of ethylene and 1 to 15% by weight of an alpha-olefin having 4 to 5 carbon atoms and improves mechanical stiffness and heat resistance of the polypropylene resin composition, As shown in Fig. The ethylene content is preferably from 0.5 to 5% by weight, more preferably from 1 to 3% by weight. When the content of ethylene is less than 0.5% by weight, the whitening resistance is deteriorated. When the content is more than 7% by weight, . Further, the alpha olefin means any alpha olefin except ethylene and propylene, and is preferably butene. When the number of carbon atoms is less than 4 or more than 5, the reactivity of the alpha-olefin with the comonomer is low during the production of the random copolymer, making it difficult to produce the copolymer. Further, it may contain 1 to 15% by weight, preferably 1 to 10% by weight, and more preferably 3 to 9% by weight of the above-mentioned alpha olefin. If the amount of the alpha-olefin is less than 1% by weight, the crystallinity becomes higher than necessary and the transparency is lowered. When the amount of the alpha-olefin is more than 15% by weight, the crystallinity and rigidity are lowered and the heat resistance is significantly lowered.

In addition, the ethylene-propylene block copolymer contains 20 to 50% by weight of ethylene and imparts impact resistance to the polypropylene resin composition and enables finely dispersing, thereby imparting both whitening resistance and transparency. The ethylene content may preferably be 20 to 40% by weight, and if it is less than 20% by weight, the impact resistance is deteriorated. If it exceeds 50% by weight, the impact resistance and whitening resistance may be deteriorated.

In addition, a fragrance material having a function such as a treatment for respiratory diseases can be coated around the fishing rod 44, thereby achieving effects such as fatigue recovery and health promotion of the user.

The functional oil may be mixed with 90 to 94% by weight of a perfume, 6 to 10% by weight of a functional oil, 50% by weight of a Heliotropium arborescens oil, And 50% by weight of St. John's Wort oil.

It is preferable that the functional oil is mixed in an amount of 6 to 10% by weight based on the perfume. If the mixing ratio of the functional oil is less than 6 wt%, the effect is insignificant. If the mixing ratio of the functional oil exceeds 10 wt%, the function is not greatly improved, but the manufacturing cost is greatly increased.
