  By the way, if a long time has passed since the rubber hose was inserted into the pipe part of the radiator, the hose was fixed to the pipe part due to the deterioration of the rubber over time, and simply pulling the hose by hand could easily come out of the pipe part. The hose had to be removed from the pipe using a special tool such as a hose clamp pliers.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to allow a hose inserted into a pipe portion of a fluid container to be easily removed using a general tool.

  In order to achieve the above object, according to the first aspect of the present invention, there is provided a fluid container including a pipe portion protruding from the outer wall surface of the fluid storage portion, and a hose inserted into the outer peripheral surface of the pipe portion. The outer wall surface is provided with a first rib connected to the outer peripheral surface of the pipe portion and a second rib located at a predetermined distance from the outer peripheral surface of the pipe portion. A fluid container is proposed.

  According to the invention described in claim 2, in addition to the structure of claim 1, the amount of protrusion of the second rib from the outer wall surface is the same as the amount of protrusion of the first rib from the outer wall surface. A small fluid container is proposed.

  According to the invention described in claim 3, in addition to the configuration of claim 1 or claim 2, the first rib includes a first protrusion that protrudes radially outward from the outer peripheral surface of the pipe portion. A fluid container is proposed in which the protruding amount of the first protrusion from the outer peripheral surface of the pipe portion is smaller than the thickness of the hose.

  According to the invention described in claim 4, in addition to the structure of any one of claims 1 to 3, the first rib is linearly formed radially outward from the outer peripheral surface of the pipe portion. A fluid container is proposed that is characterized by extending.

  According to the invention described in claim 5, in addition to the configuration of any one of claims 1 to 4, from the outer wall surface on a straight line connecting the pipe portion and the second rib. The second protrusion is larger than the protrusion of the second rib, and the pipe is on the opposite side of the pipe with the second protrusion on the straight line when viewed in the axial direction. A fluid container is proposed in which two tangents extending from the point to the outline of the second protrusion pass between the outer peripheral surface of the pipe portion and the outer peripheral surface of the hose.

  According to the invention described in claim 6, in addition to the structure of claim 5, a fluid container is proposed in which the second protrusion is provided on the second rib.

  The reserve tank 17 of the embodiment corresponds to the fluid container of the present invention, and the tank main body 17a of the embodiment corresponds to the fluid storage portion of the present invention.

  According to the configuration of the first aspect, the fluid container includes the pipe portion protruding from the outer wall surface of the fluid storage portion, and the hose is inserted into the outer peripheral surface of the pipe portion. Since the first rib connected to the outer peripheral surface of the pipe portion and the second rib located at a predetermined distance from the outer peripheral surface of the pipe portion protrude from the outer wall surface of the fluid storage portion, the first rib As a result, a gap is always formed between the outer wall surface of the fluid reservoir and the end surface of the hose, and the tip of the tool can be easily inserted into this gap. Then, with the tip of the tool in contact with the end surface of the hose, the hose can be easily extracted from the pipe portion by the lever principle by swinging the tool with the second rib as a fulcrum.

  According to the configuration of the second aspect, since the protruding amount of the second rib from the outer wall surface is the same as or smaller than the protruding amount of the first rib from the outer wall surface, the tip of the tool is connected to the outer wall surface of the fluid storage unit. The work of inserting into the gap between the end surface of the hose becomes easy.

  According to a third aspect of the present invention, the first rib includes a first protrusion that protrudes radially outward from the outer peripheral surface of the pipe portion, and the protrusion amount of the first protrusion from the outer peripheral surface of the pipe portion is the amount of the hose.

  Moreover, according to the structure of Claim 5, it comprises the 2nd protrusion part from which the protrusion amount from an outer wall surface is larger than the protrusion amount of a 2nd rib on the straight line which connects a pipe part and a 2nd rib, and the axis line of a pipe part When viewed from the direction, two tangents extending from the point on the opposite side of the pipe portion across the second protrusion on the straight line are the outer peripheral surface of the pipe portion and the outer periphery of the hose. When the hose is pulled out with a tool such as radio pliers, the second projecting part regulates the minimum closing angle of the bifurcated tip of the radio pliers, so that the bifurcated tip is connected to the pipe. The hose part can be pulled out without damaging the pipe part by being caught on the end face of the hose without contacting the part.

  According to the configuration of the sixth aspect, since the second protrusion is provided on the second rib, the amount of protrusion of the second protrusion is smaller than that in the case where the second protrusion is directly protruded on the outer wall surface. By reducing the protrusion amount of the two ribs, the strength of the second protrusion with respect to the load received from the tool is increased.

First embodiment

  Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, a radiator 11 for cooling a cooling water whose temperature has been increased by cooling an automobile engine by heat exchange with air includes an upper tank 12 disposed in a lateral direction at an upper portion thereof, and a lower portion thereof. And a radiator core 14 that connects the upper tank 12 and the lower tank 13, a fan 15 mounted on the radiator core 14, and an electric motor 16 that drives the fan 15. A reserve tank 17 for storing cooling water is fixed to one side of the radiator 11 with bolts 18 and 18, and a lower portion of the reserve tank 17 is connected to the upper tank 12 via a rubber hose 19. .

  As shown in FIGS. 2 to 4, the pipe portion 20 extending horizontally from the outer wall surface 17 b at the lower end of the tank body 17 a of the reserve tank 17 has a hollow circular cross section with a constant diameter, and the diameter increases at the tip thereof. An enormous portion 20a is formed. Although the pipe portion 20 protrudes, the outer wall surface 17b has a first rib 21 extending linearly upward and downward from the base end of the pipe portion 20, and a linear shape perpendicular to the lower end of the first rib 21 in the horizontal direction. An extending second rib 22 is projected. Both the first rib 21 and the second rib 22 have a semicircular cross section and protrude from the outer wall surface 17b, and the protrusion amount H2 of the second rib 22 from the outer wall surface 17b is the outer wall surface of the first rib 21. It is set to be the same as or smaller than the protrusion amount H1 from 17b.

  Next, the operation of the first embodiment of the present invention having the above configuration will be described.

  As shown in FIG. 5A, when the hose 19 is inserted into the pipe portion 20, the end surface 19a of the hose 19 comes into contact with the top surface of the first rib 21 protruding from the outer wall surface 17b. A gap corresponding to the protrusion amount H1 of the first rib 21 is formed between the first end surface 19a and the end surface 19a.

  Accordingly, the tapered bifurcated tip portions T and T of a tool such as a radio pliers are brought close to the pipe portion 20 from below the reserve tank 17, and the side surfaces of the tip portions T and T are along the top surface of the second rib 22. By sliding upward, the bifurcated tip portions T and T can be easily inserted into the gap between the outer wall surface 17 b and the end surface 19 a of the hose 19. At this time, since the protrusion amount H2 of the second rib 22 from the outer wall surface 17b is set to be equal to or smaller than the protrusion amount H1 of the first rib 21 from the outer wall surface 17b, the tip portions T and T are connected to the outer wall surface 17b. It becomes easy to approach to, and the operation | work which inserts the front-end | tip parts T and T into a clearance gap becomes still easier.

  Since the side surfaces of the pair of tip portions T and T of the tool inserted in this way are caught by the end surface 19a of the hose 19, as shown in FIG. 5B, the tool is moved to the arrow with the top surface of the second rib 22 as a fulcrum. When it is swung so as to be twisted in the A direction, the hose 19 whose end face 19a is strongly pressed by the tip portions T and T by the lever principle moves along the pipe portion 20 by a distance d1 in the arrow B direction.

  When the hose 19 is moved by the distance d1 along the pipe portion 20 in the direction of the arrow B by the operation of FIGS. 5A and 5B, the gap between the outer wall surface 17b and the end surface 19a of the hose 19 is enlarged from the beginning. Therefore, as shown in FIG. 6A, the tapered bifurcated tip portions T and T can be inserted deeper into the enlarged gap. Then, as shown in FIG. 6B, when the tool is again squeezed in the direction of arrow A with the top surface of the second rib 22 as a fulcrum, the hose 19 whose end surface 19a is pressed by the tip portions T and T is brought into the pipe portion 20. A further distance d2 is moved in the direction of arrow B along the line.

  When the hose 19 is pulled out by the distance d1 + d2 from the initial position in this way, the contact area between the hose 19 and the pipe portion 20 is reduced and the frictional force is reduced. Therefore, the pipe portion 20 can be simply pulled by the hand. Can be easily pulled out from.

  According to the present embodiment, even if the hose 19 is deteriorated and fixed to the pipe portion 20 and is difficult to come off, the end surface 19a of the hose 19 can be strongly pressed and pulled out from the pipe portion 20 by the lever principle. As a result, workability is greatly improved. In addition, a special tool such as a hose clamp plier is not required, and the hose 19 can be pulled out from the pipe portion 20 using a general tool such as radio pliers, so that convenience is greatly improved.

  Further, since the first rib 21 linearly extends radially outward from the outer peripheral surface of the pipe portion 20, it is possible to reduce the weight of the tank body 17a of the reserve tank 17 by minimizing the volume of the first rib 21. it can.

Second embodiment

  Next, a second embodiment of the present invention will be described with reference to FIGS.

  In the first embodiment, a pair of tips T, T of a tool such as a radio pliers is inserted into the gap between the outer wall surface 17b and the end surface 19a of the hose 19, and the end surface 19a of the hose 19 is pressed. , The inner surfaces of the pair of tip portions T, T facing each other may come into contact with the outer peripheral surface of the pipe portion 20 and damage the outer peripheral surface of the pipe portion 20. Since the outer peripheral surface of the pipe portion 20 is a portion that contacts the inner peripheral surface of the hose 19 to ensure the sealing performance, the sealing performance may be deteriorated if the outer peripheral surface of the pipe portion 20 is damaged.

  In the second embodiment, the first rib 21 includes an annular first protrusion 21 a that surrounds the outer peripheral surface of the proximal end of the pipe portion 20. The protrusion amount of the annular first protrusion 21a from the outer wall surface 17b is the same as the protrusion amount H1 of the linear portion of the first rib 21. When viewed in the axial direction of the pipe part 20, the protruding amount H <b> 4 of the first protrusion 21 a from the outer peripheral surface of the pipe part 20 to the radially outer side is set smaller than the thickness of the hose 19.

  Therefore, when the pair of tip portions T and T of the tool are inserted into the gap between the outer wall surface 17b and the end surface 19a of the hose 19, the inner surfaces of the pair of tip portions T and T are the outer peripheral surfaces of the first projecting portions 21a. By abutting, the pair of tip portions T and T cannot be closed any more, and when the tip portions T and T are swung and the hose 19 is pulled out, the inner surfaces of the tip portions T and T and the outer periphery of the pipe portion 20 A gap is secured between the pipe portion 20 and the outer peripheral surface of the pipe portion 20 is prevented from coming into contact with the tip portions T and T and being damaged.

Third embodiment

  Next, a third embodiment of the present invention will be described with reference to FIG.

  In the second embodiment, the first rib 21 includes the first projecting portion 21a that surrounds the outer peripheral surface of the proximal end of the pipe portion 20, but one of the first projecting portions 21a that actually functions is a pair. These are only the portions where the inner surfaces of the tip portions T, T abut, and the other portions are unnecessary.

  From this point of view, the third embodiment removes an unnecessary portion of the annular first protrusion 21a of the second embodiment, and a pair of tip portions T, T are only paired on the abutting portions. The first protrusions 21a and 21a are left. According to the present embodiment, it is possible to reduce the weight by reducing the volume of the first protrusion 21a of the first rib 21 while achieving the same function and effect as the second embodiment.

Fourth embodiment

  Next, a fourth embodiment of the present invention will be described based on FIG. 10 and FIG.

  In the third embodiment, a pair of first protrusions 21a of the second embodiment is paired only with a portion where the inner surfaces of a pair of tip portions T and T of a tool such as radio pliers abut. In the fourth embodiment, the side facing the second rib 22 is added to the pair of first protrusions 21a, 21a of the third embodiment. Further, one first protrusion 21a is provided. Therefore, the lower half of the linear first rib 21 extending downward from the pipe portion 20 toward the second rib 22 is eliminated. The newly added first protrusion 21 a on the lower side of the pipe part 20 has the same shape as the existing first protrusions 21 a and 21 a on both the left and right sides of the pipe part 20.

  According to the present embodiment, the tip portion T of a tool such as a flat-blade screwdriver is inserted to a position where it abuts on the lower surface of the lower first projection 21a, and is swung so as to pry the tool. The hose 19 can be pulled out without damaging the outer peripheral surface of 20, and a tool such as a minus driver more general than radio pliers can be used, thereby further improving convenience. In this embodiment, it is needless to say that a tool such as a radio pliers can be used as in the third embodiment.

Fifth embodiment

  Next, a fifth embodiment of the present invention will be described with reference to FIGS.

  In the fifth embodiment, instead of the first protrusion 21a of the first rib 21 of the second to fourth embodiments, a second protrusion 22a having a protrusion amount H3 is provided on the second rib 22. The second protrusion 22 a protrudes higher than the top surface of the first rib 21 and the top surface of the second rib 22. Then, a pair of tip portions T and T of a tool such as a radio pliers are inserted into a gap between the outer wall surface 17b and the end surface 19a of the hose 19, and the pair of tip portions T and T are closed to form the second protrusion 22a. When viewed in the axial direction of the pipe portion 20 in the sandwiched state, the inner surfaces of the tip portions T and T are on the radially outer side with respect to the outer peripheral surface of the pipe portion 20 and on the radially inner side with respect to the outer peripheral surface of the hose 19.

  In other words, the point 2 on the straight line L1 extending from the center of the pipe portion 20 through the center of the second rib 22 (the intersection of the inner surfaces of the pair of tip portions T and T) is in contact with the left and right ends of the second protrusion 22a. When the tangent lines L2 and L2 are drawn, the tangent lines L2 and L2 pass between the outer peripheral surface of the pipe portion 20 and the outer peripheral surface of the hose 19.

  As a result, also according to the present embodiment, the side surfaces of the pair of tip portions T and T are controlled by restricting the maximum closing amount of the pair of tip portions T and T of the tool such as the radio pliers by the second protrusion 22a. It is possible to prevent the inner surfaces of the pair of tip portions T, T from coming into contact with the outer peripheral surface of the pipe portion 20 and being damaged while ensuring that the hose 19 is caught on the end surface 19a.

  In particular, since the second protrusion 22a is provided on the second rib 22, the amount of protrusion of the second protrusion 22a is greater than that of the second rib 22 compared to the case where the second protrusion 22a is directly protruded from the outer wall surface 17b. The strength of the second protrusion 22a with respect to the load received from the tool is increased by reducing the amount corresponding to the protrusion amount.

  The embodiments of the present invention have been described above, but various design changes can be made without departing from the scope of the present invention.

  For example, the fluid container of the present invention is not limited to the reserve tank 17 of the radiator 11 according to the embodiment.

  In the fifth embodiment, the second protrusion 22a is provided on the second rib 22. However, the second protrusion 22a is provided at an arbitrary position on the straight line L1 extending from the center of the pipe 20 through the center of the second rib 22. A second protrusion 22a can be provided.
