Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elastic sheet used for gripping a pipe body to be installed in a pipe or a joint thereof, and more specifically, a pipe which is arranged to accommodate and arrange a cable, a fluid, etc. The present invention relates to an elastic sheet for gripping that is interposed to support in a watertight manner.
[0002]
[Prior art]
This type of elastic sheet is made of an elastic material such as rubber, and is wrapped around a pipe body or its joint, and is held and tightened by a sleeve-like gripping member to support the turbulence and fluid in the support section. In order to prevent leakage, conventionally, the sheet is gripped with an elastic sheet having both flat surfaces and an O-ring.
[0003]
Further, as an elastic sheet, both flat surfaces or one surface of a flat surface is formed as an uneven rough surface, and the frictional resistance action by the rough surface is used to prevent the detachment and fluid leakage in the support portion.
[0004]
[Problems to be solved by the invention]
As described above, this type of conventional elastic sheet for gripping is fastened and fixed by utilizing the elasticity of the elastic material itself, so that it depends on the material and configuration of the tube to be clamped and clamped by the gripping member. Due to the difference in strength and rigidity, pipes with low strength and rigidity, such as thin-walled pipes and pipes made of synthetic resin materials, will cause excessive holding and tightening force on the gripping member to cause the elasticity of the elastic sheet itself. However, it cannot be absorbed by itself, and there is a possibility that the pipe body may be deformed or damaged, and the tight sealability in the fluid piping is not sufficient.
[0005]
Therefore, in order to support and fix the arranged pipe body, a precise and skilled work without causing turbulence and fluid leakage is required for holding and clamping the holding member with the elastic sheet interposed therebetween, and the holding pipe body Depending on the material and configuration, the elasticity of the elastic sheet itself has been complicated and used.
[0006]
The present invention solves the above-mentioned problems in the elastic sheet for gripping the tube body, and in the tube body gripping portion that suspends, supports, or supports the pipe for housing and laying cables or the like in a branched shape. The gripping force works efficiently without damaging the tube being held, and so far it has a water-tight (leakage prevention) structure with a separate partial seal such as an O-ring. In view of the fact that the effect was not obtained, an object is to provide an elastic sheet in which a tight connection branch configuration can be easily obtained by a unique watertight configuration.
[0007]
[Means for Solving the Problems]
In order to achieve the above-described object of the elastic sheet for gripping a tube body, the present invention has an adsorption depression part whose depression is recessed in the center on one side of a sheet body made of an elastic material such as rubber and soft synthetic resin, and the peripheral edge thereof. Proposed an elastic sheet for gripping a tubular body with many protruding parts formed on a horizontal outer ring edge projecting on one side and the other side formed on a flat surface, When the flat plate substrate portion is held and clamped by the gripping member via the tube surface side of the tube gripping elastic sheet for gripping the elastic surface for gripping the tube body, it is provided on the protrusion portion. The cavity of the adsorbing depression makes the protrusions more elastic and gives a smooth and fine elasticity on one side, which absorbs the compressive force caused by tightening the gripping member and damages the tube In addition, it can be gripped tightly in combination with the elasticity of the flat substrate portion on the other side.
[0008]
In particular, the suction contact surface formed by the cavity of the suction recess and the outer ring edge formed at the top of the projecting portion is tightly tightened in a state of being attracted to the side surface of the tubular body by the tightening force of the gripping member. On the other hand, the gripping part can be firmly gripped and supported without causing reluctance.
[0009]
An elastic sheet for gripping a tubular body in which a peripheral edge of an opening formed by punching a part of a sheet body is protruded toward the projecting portion to form a ridge packing slightly higher than the projecting portion is an existing tube described later. It is used to branch and connect the body with a branch piping device, in addition to tight gripping due to the elasticity of the protruding portion, by integrally molding a slightly tall protrusion packing in the opening of the sheet body, In order to tightly seal the periphery of the pipe branching portion in series, the protruding packing is strongly abutted at the gripping support portion of the branch piping device, and the perimeter of the pipe branching portion is tightly sealed in series by preventing the loose movement of the packing member. Prevents fluid leakage.
[0010]
An elastic sheet for gripping a tubular body, which is integrally formed into a two-layer structure in which the substrate side of the sheet body is made of a hard elastic material together with the ridge packing and the protruding side is made of a relatively soft elastic material, The elasticity of the buttock surface becomes smoother, and the absorption force of the compression force by tightening the gripping member is made to work efficiently, and the adsorption force to the tube surface is increased to further improve the tube gripping support force. .
[0011]
The protruding frame edge projecting from the peripheral edge of the sheet body becomes a tension bone of the sheet body itself, and holds the flexible whole surface on the elastic sheet in a stretched state without slack, especially the peripheral edge edge is waved. Therefore, the flat plate shape can be secured without being tightly wound around the outer surface of the tube body and can be firmly fixedly supported by the gripping member.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of an elastic sheet for holding a tube according to the present invention will be described below with reference to FIGS.
[0013]
【Example】
An embodiment of an elastic sheet for gripping a tube body embodying the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 is a perspective view showing a part of the elastic sheet for gripping a tube body, and FIG. FIG. 3 is a side view of the main part of the tube gripped and supported by using the elastic sheet, FIG. 4 is an enlarged front view of the main part of the tube, and FIG. 5 is the same pipe body. It is a partial enlarged vertical front view which shows the contact | adherence effect | action of the elastic sheet in the principal part.
[0014]
As shown in FIGS. 1 and 2, the elastic sheet has an adsorbing depression 2a having a concave center at one side of the entire sheet 1 made of rubber, soft synthetic resin, or other equivalent elastic material, and a peripheral edge thereof. A plurality of short cylindrical protrusions 2 each having an outer ring edge 2b formed as a horizontal apex are provided so as to be integrally formed on a flat plate portion 1b.
[0015]
Examples of using this elastic sheet will be described with reference to FIGS. 3 to 5. The sheet body 1 is placed on the side of the joint body of the tubular bodies 4 and 4 having a circular cross-section for accommodating and arranging cables such as electric wirings.

Due to the pressing deformation action, the sheet body 1 effectively absorbs excessive tightening and gripping force of the gripping support portion 5 and closely adheres to the tube body 4. Without obtaining a long and stable and tight grip support, it accommodates cables such as communication lines and electrical lines, protects the wiring, and firmly arranges and supports the tube 4 such as sending fluid, These communication lines are safely supported and secured.
[0017]
At the same time, due to the suction action by the concave hollow portion of the suction recess portion 2a of the protrusion portion 2 and the outer ring edge 2b of the periphery thereof, the protrusion portions 2 and 2 of the sheet body 1 become the tubular body 4 surface, that is, the curved surface. Although omitted, in a pipe having a square or polygonal cross section, it is adsorbed to the bent surface and flat surface, and the sheet body 1 comes into close contact with the surface of the tube body 4 without slipping, and the clamping gripping force at the gripping members 5a and 5a Can work efficiently.
[0018]
Accordingly, it is possible to grip and support the tube body 4 tightly and firmly without being deformed or cracked by the tightening force of the gripping members 5a and 5a, and in particular, a relatively thin wall that accommodates and arranges electric wiring and the like. The effect is remarkably great in the tubular body 4.
[0019]
In the above description, the usage example in which the sheet body 1 is wound around the joints of the tubular bodies 4 and 4 has been described. However, the sheet body 1 is interposed in the middle of the tubular body 4 and supported by being suspended. It is also possible to hold and suspend and support, hold and support, or embed.
[0020]

The sheet is wound around the protruding portion 2 side, and the outside is held by a holding member 5a provided with a recessed receiving portion 5f having a fitting portion 5g having a through-hole shape on a recessed surface having a semicircular cross section, and a sheet By fitting and fixing the projecting portion 1c of the body 1a to the fitting portion 5g and fastening with the bolt nuts 5b and 5b, the upper side on the trunk side which is a part of the branch portion of the tubular body 4 is the concave receiving portion 5f. The cutting guide 6b is held and fixed so as to enter the cutting guide 6b at a right angle from the intersection with the cutting guide 6b.
[0023]
In the branch piping device 6, an opening / closing ball 6 h that is rotated by an opening / closing operation spindle 6 i is loaded in the branch passage 6 g of the branch portion 6 f, and the cutting guide 6 b is provided with the front open tip side on the cutting blade 6 d and the bottom on the rear side. A bottomed cylindrical cutter 6c having a storage section inside is slidably loaded on the front side (rear wall side) of the intersection and provided on the rear wall of the cutting guide 6b of the saddle body 6a. The tip of the threaded rod 6e screwed to the bottom is pressed against the bottom of the cutter 6c, and the handle (not shown) attached to the base end of the threaded rod 6e that can be screwed out from the rear wall is turned to rotate the threaded rod 6e. Thus, the cutter 6c is propelled forward along the wall surface of the cutting guide 6b, screwed and fixed to cover the front wall of the cutting guide 6b like a cover, and the sheet body 1 in the gripping support portion 5 is configured. Ridge packing 3 is closely attached to the side surface of the cylinder 4 barrel around the branch portion opened by cutting of the cutter 6c and sealed in a water-tight manner, and is integrated with the rib packing 3 on the other branch portion on the barrel side following this. The projecting projecting portion 2 surface side is wound around, and the gripping support portion 5 is increased in gripping force by being in close contact with each other by the elastic and adsorbing action of the adsorbing recess 2a and the outer ring edge 2b of the projecting portions 2, 2, The tube body 4 is supported and fixed in a watertight manner.
[0024]

Since the body 4 is closely attached to the side surface of the body, the watertight seal of the branch connection portion is ensured more precisely.
[0026]
【Example】
As shown in FIG. 7, the projecting parts 2 and 2 of the sheet body 1 are integrally formed into a two-layer structure with a soft elastic material, and the substrate part 1 b side layer together with the ridge packing 3 with a relatively hard elastic material. By configuring as above, the elasticity and adsorption action of the protrusions 2 and 2 group surfaces work more effectively, and the sheet body 1 itself is kept in a flexible flat plate shape by the relatively hard substrate part 1b. Therefore, the attaching work to the tube body 4 is easy, and the gripping force by the gripping support portion 5 is further increased. In addition, the rib packing 3 can be fixedly interposed and fixed by the sheet body 1, and the sealing degree to the side surface of the tube body 4 is increased, and fluid leakage from the branch connection portion can be completely prevented. it can.
[0027]

[0028]
In addition, since the sheet body 1 is used while being wound around the body side surface of the tube body 4 with the protrusion 2 group side inward, the height of the protrusion packing 3 is slightly higher than that of the protrusion 2. Although the structure which ensures the water-tightness by the ridge packing 3 has been described, the height of the ridge packing 3 can be increased by utilizing the rich elasticity of the ridges 2 group contracted by the cavity of the suction recess 2a. Even if it is equivalent to the projecting portion 2, its effect can be obtained sufficiently.
[0029]
In each of the embodiments described above, the outer ring edge 2b and the projecting frame edge 2c of the projecting portion 2 of the sheet body 1 and the tops of the protrusion packings 3 are described as flat surfaces. Even if the outer ring edge 2b and the projecting frame edge 2c of the projecting part 2 having a semicircular cross-section or a triangular pyramid-shaped cross section and the ridge packing 3 are formed horizontally if the structure is formed without any bias. A uniform contact surface is obtained, and the protrusion 2 has an adsorption action, so it is naturally included in the practice of the present invention. In addition to the circular shape described for the shape of the protrusion 2, a square, It can be projected and formed into a columnar shape or a trapezoidal shape having an arbitrary pattern such as a rectangle, a rhombus, a triangle, other polygons, an ellipse, an oval, and a bowl.
[0030]
In addition, the opening 3a of the sheet body 1 has also been described as being oval-shaped in the above-described embodiment, but other shapes such as a circle, an oval, a rectangle, and a bowl are formed and protruded accordingly. The strip packing 3 is projected.
[0031]
【The invention's effect】
The elastic sheet for gripping a tube body according to the present invention has the above-described configuration, and it has an excessive elasticity at the gripping portion due to the abundant elastic action by the suction recess portion of the protrusion projecting on the sheet body surface, and further by the suction action. It absorbs the tightening force of the tube and grips it tightly to the barrel side surface of the tube, allowing the grip force to the tube to work efficiently, causing the tube to deform, crack, etc. It is possible to hold and fix firmly without causing any looseness in gripping without vibration.
[0032]
The ridge packing provided on the sheet body is coupled with the sheet body that is firmly fixedly supported by the holding support portion in combination with the elastic and adsorbing action of the ridge portion, and is branched from the existing pipe body. Since it can be pressure-bonded to the periphery of the opening in a surrounding state and a tight seal state that does not change is maintained, it is possible to reliably prevent the fluid from leaking from the branch opening (connection) part for a long time.
