Description

The present invention relates to a cover for preventing oil scattering. In particular, the present invention relates to an oil splash prevention cover that covers a hydraulic hose and prevents oil leaking from the hydraulic hose from splashing.

Conventionally, a hydraulic system has been used in construction machines such as power excavators and forklifts, press machines, pressurizing devices, and luggage elevators. This hydraulic system uses flood control as the power for operation, and sends out a high-pressure fluid created by a hydraulic pump with a hydraulic hose, and a piston or hydraulic motor (generally called an actuator) installed in a predetermined place. ) Is a power system that works.

In such a hydraulic system, the hydraulic hose used may deteriorate over time, or some object may come into contact with the hydraulic hose during use, which may cause damage such as crevices or holes in a part of the hydraulic hose. Fluid (oil) may scatter out of the hydraulic hose. In order to prevent such oil scattering, an oil scattering prevention cover that covers the outer circumference of the hydraulic hose has been used in recent years.

Such an oil splash prevention cover includes, for example, a strip-shaped female hook-and-loop fastener provided along each side edge portion of a pair of side edges of a long sheet-like base material facing each other. Those equipped with a female hook-and-loop fastener are known. Such an oil splash prevention cover is used by covering the periphery of the hydraulic hose in a tubular shape and fixing the male and female hook-and-loop fasteners to each other.

A conventionally known cover for preventing oil scattering exerts an effect of suppressing oil scattering from a damaged portion generated in a hydraulic hose, but further improvement is desired. For example, the oil splash prevention cover is configured as a roll body wound in a roll shape starting from one end of the oil splash prevention cover in the unfolded state in the manufacturing process, and the oil in the roll body shape. The user who has purchased the shatterproof cover needs to pull out the oil shatterproof cover from the roll body by a required predetermined length and cut it. When pulling out and cutting, the user must use a tape measure or the like to cut while measuring the length actually pulled out, and it takes a lot of time to set the oil splash prevention cover. There is a problem that labor is required, and a cover for preventing oil scattering that can be set more easily on the hydraulic hose has been desired.

The present invention has been made to contribute to such a demand, and an object of the present invention is to provide a cover for preventing oil scattering that can further simplify the setting work on the hydraulic hose.

One is provided on the front surface side of the sheet-like base material, and the other is provided with a pair of hook-and-loop fastener strip pieces installed on the back surface side of the sheet-like base material. The base material forms a cylinder that surrounds the hydraulic hose in a state where the pair of hook-and-loop fastener strips overlap each other, and each of the pair of hook-and-loop fastener strips is formed at predetermined pitch intervals. The scale markings provided by the one hook-and-loop fastener strip piece and the scale markings provided by the other hook-and-loop fastener strip piece are formed at the same position in the longitudinal direction of the sheet-like base material. Each of the scale markings is achieved by an oil splash prevention cover, which is formed by printing.

Further, in the oil splash prevention cover, it is preferable that each of the scale markings is a linear marking extending in a direction perpendicular to the longitudinal direction of the sheet-like base material.

Further, it is preferable that the hook-and-loop fastener strips are arranged on both side edges of the sheet-like base material along the longitudinal direction.

Further, the sheet-like base material is formed by weaving a plurality of warp threads arranged along the longitudinal axis and a plurality of weft threads arranged along a direction substantially perpendicular to the longitudinal direction of the warp threads. Is preferable.

Further, in FIG. 4, it is described that a gap is formed between the warp threads 11 or between the weft threads 12, but this is expressed by forming a gap in order to understand the configuration. In the actual oil splash prevention cover 1, the warp threads 11 and the weft threads 12 are in close contact with each other. Various filamentous members can be adopted as the filamentous body constituting the sheet-like substrate 2. Further, the filamentous body forming the sheet-like base material 2 is preferably formed from a fiber material having a heat resistance of 100 ° C. or higher. Examples of such fiber materials include synthetic polymers such as polyester and polypropylene, aramid such as Kevlar, and nylon. When the sheet-like base material 2 is constructed using a filament formed from heat-resistant fibers, for example, it is possible to stably use the oil scattering prevention cover 1 even in a usage environment of 70 ° C. or higher, which is preferable.

The pair of hook-and-loop fastener strips 3 are fixing means for maintaining the tubular wound coating state of the sheet-shaped base material 2 coated on the surface of the hydraulic hose Z in a tubular shape. The pair of hook-and-loop fastener strips 3 are arranged in a strip shape along the longitudinal direction of the sheet-shaped base material 2, and one hook-and-loop fastener strip 31 is on the surface side of the sheet-shaped base material 2 and the other hook-and-loop fastener strip. The piece 32 is installed on the back surface side of the sheet-shaped base material 2. In the present embodiment, the hook-and-loop fastener strips 31 and 32 are arranged in strips along the longitudinal direction of the side edges on each of the side edge portions 25 and 26 along the longitudinal direction of the sheet-shaped base material 2. There is. Here, the side edge portions 25 and 26 become side edge portions along the longitudinal direction of the hydraulic hose Z when the oil splash prevention cover 1 is wound around the hydraulic hose Z and installed. Further, since the oil splash prevention cover 1 shown in FIG. 1 is covered by winding the hydraulic hose Z in a single layer as shown in FIG. 3, the length of the sheet-shaped base material 2 in the lateral direction is increased. It is formed so as to be slightly longer than the length corresponding to the peripheral length of the hydraulic hose Z, and the side edges 25 and 26 overlap each other when the sheet-shaped base material 2 is wound around the hydraulic hose Z. Has been done. The pair of hook-and-loop fastener strips 3 (31, 32) are arranged corresponding to the overlapping side edges 25, 26.

Further, regarding the pair of hook-and-loop fastener strips 3, a so-called female hook-and-loop fastener strip 31 is arranged on the front surface side of the sheet-shaped base material 2, and the male hook-and-loop fastener strip 32 is placed on the back surface side of the sheet-shaped base material 2. It is preferable to configure the oil splash prevention cover 1 so as to be arranged in. When such a configuration is adopted, when the oil splash prevention cover 1 is wound around the hydraulic hose Z, the joint surface of the male hook-and-loop fastener strip 32 faces the hydraulic hose Z side, and the male The joint surface of the hook-and-loop fastener band piece 32 of the mold can be set so as not to face outward. As a result, it is possible to prevent the hook constituting the male hook-and-loop fastener band piece 32 from coming into direct contact with an external obstacle, and as a result, it is possible to prevent the hook from falling over. , The engagement force of the pair of hook-and-loop fastener strips 3 can be maintained for a long period of time.

Further, each of the pair of hook-and-loop fastener strip pieces 3 (31, 32) is provided with a plurality of scale markings 33 formed at predetermined pitch intervals. In the present embodiment, each scale marking 33 is formed on the surfaces of the hook-and-loop fastener strips 31 and 32 by printing, and each scale marking 33 is perpendicular to the longitudinal direction of the sheet-like base material 2. It is formed as a linear marking extending in various directions. Further, each scale marking 33 included in the one surface fastener band piece 31 and each scale marking 33 included in the other surface fastener band piece 32 are formed at the same position in the longitudinal direction of the sheet-shaped base material 2. Here, the predetermined pitch between the scale markings 33 is not particularly limited, but it is preferable that the pitch is set to 10 cm and each scale marking is formed. The pitch is not limited to 10 cm, and can be set as any dimension such as 20 cm or 50 cm.

The color of the scale marking 33 is not particularly limited, but it is preferable to select a conspicuous color in consideration of the color of the hook-and-loop fastener strips 31 and 32.

As described above, the oil splash prevention cover 1 according to the present invention has a plurality of scale markings 33 formed on the surfaces of the hook-and-loop fastener strips 31 and 32 at predetermined pitch intervals. Based on the number of the scale markings 33, the length of the oil splash prevention cover 1 can be known. That is, a user who has purchased the oil scattering prevention cover 1 wound in a roll shape pulls out the oil scattering prevention cover 1 from the roll body by a required predetermined length and cuts it at a predetermined pitch. The required length of the oil splash prevention cover 1 can be easily recognized based on the plurality of scale markings 33 formed at each interval, and as in the conventional case, a tape measure or the like is used separately to actually recognize the length. There is no need to cut while measuring the drawn length.

Further, in the oil splash prevention cover 1 according to the present invention, each scale marking 33 provided on one surface fastener band piece 31 and each scale marking 33 provided on the other surface fastener band piece 32 are a sheet-like base material 2. When cutting the oil splash prevention cover 1 to a predetermined length, the user uses the scale marking 33 provided on one of the hook-and-loop fastener strips 31 as the cutting start end. At the same time, it is possible to proceed with cutting by using the scale marking 33 provided on the other surface fastener band piece 32 as the cutting end. That is, it is possible to proceed with cutting so that the cut end surface of the oil splash prevention cover 1 has a clean straight line. Here, the user who cuts the oil scattering prevention cover 1 including the sheet-shaped base material 2 in which the warp 11 and the weft 12 are usually woven is formed along the lateral direction of the sheet-shaped base material 2. An attempt is made to cut along the streaks of the texture to be formed, but the texture is not formed perpendicular to the longitudinal direction of the sheet-like base material 2, and the texture is not formed in the longitudinal direction of the sheet-like base material 2. Some are formed with a slight inclination. In such a case, if cutting is advanced along the lines of the texture, the cutting line of the sheet-like base material 2 is inclined, causing a cutting defect, and the oil splash prevention cover 1 is attached to the hydraulic hose Z. When the hose is wound around and installed, a part of the hydraulic hose Z to be protected may be exposed due to this poor cutting. However, as described above, in the present invention, the scale marking 33 provided on one surface fastener band piece 31 is used as the cutting start end, and the scale marking 33 provided on the other surface fastener band piece 32 is used as the cutting end point to proceed with cutting. As a result, the cutting line of the sheet-shaped base material 2 can be cut so as to be substantially perpendicular to the longitudinal direction of the sheet-shaped base material 2, and the oil splash prevention cover 1 can be cut with the hydraulic hose Z. It is possible to effectively prevent a part of the hydraulic hose Z to be protected from being exposed when the hose Z is wound around and installed.

Further, in the present invention, since each scale marking 33 is formed on the surfaces of the hook-and-loop fastener strips 31 and 32 on each surface by printing, it is effective to prevent the scale marking 33 from completely disappearing due to friction. Will be done. Specifically, the hook-and-loop fastener strips 31 and 32 on which the scale marking 33 is printed have a structure in which a plurality of loop-shaped protrusions and hook-shaped protrusions to be worn are formed on the base material. The ink used during printing is printed not only on the loop-shaped protrusions and hook-shaped protrusions, but also on the base material. The ink printed on the loop-shaped protrusions and hook-shaped protrusions is relatively easy to disappear due to friction, etc., but the ink printed on the base material is protected by the loop-shaped protrusions and hook-shaped protrusions. This prevents it from disappearing due to friction. In this way, the scale markings 33 formed by printing on the surfaces of the hook-and-loop fastener strips 31 and 32 on each surface are less likely to disappear.

Although the oil splash prevention cover 1 according to the present invention has been described above, the specific configuration is not limited to the above embodiment. In the above embodiment, the oil scattering prevention cover 1 wound around a single hydraulic hose Z has been described, but the present invention is not limited to such a configuration, and for example, a plurality of hydraulic hoses Z can be collectively covered. The oil splash prevention cover 1 may be configured as described above. When such a configuration is adopted, the length dimension in the winding direction of the sheet-shaped base material 2 with respect to the plurality of hydraulic hoses Z bundled together is the peripheral length of the plurality of hydraulic hoses Z bundled together. It may be set to be slightly longer than.
