Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a hose clamp expanding temporary fixing device.

[0002]

[Prior art]

 Conventionally, as one type of hose clamp, as shown in FIG. 10 and FIG. 11, both ends of a band-shaped leaf spring body A formed in an annular shape are staggered and extend along the circumferential direction of the band-shaped leaf spring body A, respectively. Protruding pieces B and C were provided, and the distal ends of the extending pieces B and C were bent outward along the radial direction of the band-shaped leaf spring main body A, and the portions were formed as knobs B 'and C'. There is a hose clamp D, which needs to be temporarily fixed in an expanded state until it is used. Further, as a member for that purpose, the diameter expanding temporary fixing device E shown in FIGS. 10 and 11 has been conventionally used.

[0003] The diameter expanding temporary fixing device E is formed by cutting and raising a tongue-shaped knob portion G on a U-shaped main body F and extending it upward. When using this for temporary fixing, the U-shaped main body F is put over the knobs B 'and C' of the hose clamp D expanded in diameter with an appropriate tool. When the hose clamp is removed to reduce the diameter of the hose clamp, the knob G is gripped by a member such as pliers as shown in FIG. 11 and pulled upward.

[0004]

[Problems to be solved by the invention]

 However, there is a problem in the conventional hose clamp diameter expanding temporary fixing device. Since the tongue-shaped knob G extends straight upward from the U-shaped main body F, that is, in the same direction as the pulling direction between the holding parts such as pliers as shown in FIG. It is slippery when trying to pull. For this reason, it is necessary to spend wasted time to remove it, and it also requires wasted effort because it must be held firmly.

[0005] The present invention has been made in view of the above-mentioned point, and it is possible to solve the above-mentioned problem by preventing slipping between the holding portions of the pliers or the like when the pliers are pulled off. In addition, the hose clamp diameter can be easily and securely removed with tools such as pins and screwdrivers, and the U-shaped body can be easily covered. They do not provide temporary fasteners.

[0006]

[Means for Solving the Problems]

 Therefore, the gist of the present invention is to provide a hose clamp having a U-shaped main body in which a knob formed of a pair of small projections extending in the front-rear direction is integrally formed at the center of the top of the main body. It is in the temporary fastener.

In the above configuration, an insertion notch such as a pin may be provided in the center of the upper part of the opposing sandwiching portions in the U-shaped main body.

Further, in the above configuration, a vertical slit may be provided at the center of the opposed sandwiching portions of the U-shaped main body.

[0009]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view, FIG. 2 is a front view, FIG. 3 is a left side view, FIG. 4 is a plan view, FIG. 5 is a bottom view, FIG. 6 is a perspective view in use, and FIG. FIG. 8 is an explanatory view of an example of a case where the hose clamp is put on a hose clamp, and FIG. 9 is an explanatory view of an example of a case where the hose clamp is put on a hose clamp.

In the drawing, reference numeral 1 denotes a hose clamp diameter expanding temporary fixing tool made of a metal plate. The hose clamp diameter expanding temporary fixing device 1 has a knob portion 3 composed of a pair of small projections 3a, 3b projecting in the front-rear direction at the center of the top of a U-shaped main body 2 having opposing sandwiching portions 2a, 2b. Are integrally formed.

In addition, insertion notches 4 and 4 such as pins are provided in the center of the upper part of the opposing sandwiching portions 2 a and 2 b in the U-shaped main body 2.

[0012] Furthermore, longitudinal slits 5 and 5 are provided in the center of the opposed sandwiching portions 2a and 2b of the U-shaped main body 2. In the figures, reference numeral 6 denotes a hose clamp, 6a and 6b denote knobs of the hose clamp, and 7 denotes tools such as pliers and pliers.

Next, the operation of the above embodiment will be described. The diameter of the hose clamp 6 is expanded by using an appropriate tool, and in this state, the knobs 6a and 6b are temporarily covered with the U-shaped main body 2 from above, as in the related art. When the U-shaped main body 2 is removed from the knobs 6a and 6b of the hose clamp 6, a tool 7 such as pliers or pliers is used as shown in FIG. At this time, the pair of small projections 3a, 3b of the knob 3 project in the front-rear direction of the U-shaped main body 2, that is, in the direction perpendicular to the pulling direction between the clamping portions of the tool 7 such as a pliers or pliers. Because it is overhanging, it is more likely to be caught and less slippery.

Further, since the notches 4 and 4 for inserting pins and the like are provided at the center of the upper portions of the opposed sandwiching portions 2 a and 2 b of the U-shaped main body 2, heavy weight such as pliers and pliers is used. Instead of using a tool, it can be removed using a lightweight and small pin or screwdriver. In this case, a pin, a screwdriver, or the like is inserted into the notch 4, 4 for inserting the pin or the like, and the pin is lifted upward to pry.

FIGS. 8 and 9 show an example of a method of putting the hose clamp diameter expanding temporary fixing device 1 of the present invention on the knob of the hose clamp. That is, in the present embodiment, since the vertical slits 5 and 5 are provided in the center of the opposed sandwiching portions 2a and 2b of the U-shaped main body 2, the thickness of the tool is reduced by sandwiching the knob of the hose clamp. If the clamping tool 8 having a small thickness is used, the U-shaped main body 2 can be put on the knob of the hose clamp while being clamped by the tool 8. Therefore, the operation of putting the U-shaped main body 2 can be performed easily and quickly. In addition, since the pinching tool 8 is inserted into the vertical slits 5, 5 of the U-shaped main body 2, it does not hinder the putting. In addition, the hose clamp can be temporarily fixed regardless of the thickness, width, and inner diameter of the hose clamp.

Furthermore, in the conventional method of expanding the diameter of the hose clamp by pushing the inner surface of the ring outward, there is a risk of damaging the inner surface of the hose clamp. Difficult. However, in the present embodiment, the hose clamp can be clamped from both sides, so that the inner surface of the hose clamp is not damaged, and the hose clamp can be implemented with a small diameter hose clamp. You can do it.

[0017]

[Effect of the invention]

 The present invention has the configuration and operation as described above, and a knob portion composed of a pair of small projections projecting in the front-rear direction is integrally formed at the center of the top of the U-shaped main body, that is, the U-shaped main body. When the hook is removed from the knob of the hose clamp, the pair of small projections protrude in the direction perpendicular to the pulling direction between the holding parts of the tool such as pliers, so that the hook becomes strong and the slip becomes difficult. It is.

Further, if a notch for insertion such as a pin is provided at the center of the upper portion of the opposing sandwiching portions in the U-shaped main body, a lightweight and compact device can be used without using a heavy tool such as pliers or pliers. It is also possible to remove using a pin or a screwdriver.

Furthermore, if a vertical slit is provided at the center of the opposed clamping portions of the U-shaped main body, the thickness, width, and width of the hose clamp can be reduced by using a thin clamping tool. The U-shaped main body can be covered easily and quickly without being affected by the inner diameter, etc. In addition, the inner diameter of the hose clamp is not damaged when the hose clamp is expanded, and the diameter can be reduced. Large diameter hose clamps can be easily expanded.
