Definitions
- the present invention relates to a plate clamp used for holding a tube.
- a conventional plate clamp is composed of a tube penetration hole 1 through which a tube 2 is inserted, a slit portion 4 for clamping the tube 2, and a tube calling portion 3.
- the force to slide the tube 2 in the tube passage hole 1 to the slit part 4 Depending on the tube material and tube dimensions, the tube 2 is deformed into a U shape as shown in Fig. 2.
- the sliding resistance may be high and it may be difficult to slide, and if the tube is slid repeatedly, the tube 2 may be worn and the strength may be reduced.
- Patent Document 2 a lubricant coating on the inner surface of a clamp has been proposed (Patent Document 2).
- Patent Document 1 Shokai Aki 63-1541
- Patent Document 2 Patent No. 3517284
- a tube for example, a clamp resistance when a tube is slid from a through hole to a slit portion is low, a clamp operation is easy, and even when the inside of the clamp is treated with a lubricant, the slit of the clamp It is an object of the present invention to provide a plate clamp with a low risk that a tube tightly attached to the part will come off from the slit part.
- the present invention provides a slit portion for tightly holding a tube on a plate-like member, a tube inlet portion that is a groove that expands forward from the tip portion of the slit portion, and the tube inlet portion.
- a clamp in which a continuous tube penetration hole is formed, wherein the tube insertion portion and the slit The above problem could be solved by providing a tube clamp characterized by having a tube stopper on only one side of the boundary of the tube.
- the clamp of the present invention by forming a lubricating layer on the inner surface of the clamp in order to reduce the clamping resistance when sliding the tube into the slit portion and facilitate the clamping operation, It is possible to eliminate the risk that the tube narrowly attached to the slit portion of the clamp may come off the slit portion force.
- the tube when the angle of the tube entrance portion is increased, for example, when the angle exceeds 30 degrees, the tube slides toward the slit portion that generates the through-hole force.
- the tube is deformed into a “ ⁇ ” shape as shown in FIG. 2 at the inlet portion of the slit portion adjacent to the inlet side of the tube, making the slide difficult.
- the sliding angle of the tube is reduced, for example, 20 ⁇ 10 degrees, preferably 20 ⁇ 5 degrees, and more preferably about 20 degrees, the tube is squeezed when sliding. It is possible to transform into a single letter shape, and the sliding resistance when sliding toward the slit portion where the above-mentioned punching force is reduced becomes a very effective means for solving the above problems.
- FIG. 1 is a diagram illustrating a configuration of a conventional plate clamp in which an angle of a tube insertion portion is 40 degrees and a slide resistance portion is not present.
- FIG. 2 is a diagram illustrating that the tube is deformed into a “ ⁇ ” shape in the plate clamp of FIG.
- FIG. 3 is a diagram illustrating a configuration of a plate clamp according to the present invention in which an angle of a tube insertion portion is 20 degrees and a slide resistance portion is present.
- FIG. 4 is a diagram illustrating that the tube is deformed into a single letter in the plate clamp of FIG.
- the plate clamp of the present embodiment is a polypropylene polyacetal resin in which all the components are made by integral molding.
- the clamp has a slit portion 4 for tightly holding the tube 2 on a plate-like member, a tube inlet portion 3 that is a groove that expands forward from the tip portion of the slit portion 4, and the tube inlet portion.
- a tube passage hole 1 continuous to the portion 3; and a tube stopper portion 5 formed only on one side of a boundary portion between the tube insertion portion 3 and the slit portion 4.
- the tube passage hole 1 is formed with a part thereof being opened, but the tube passage hole of the plate clamp of the present invention may have a structure having no open portion. Yes.
- the tube entrance part 3 has a function of facilitating the sliding of the tube from the through hole 1 to the slit part 4, and is loosely capable of deforming the tube 2 into a single character at the boundary part of the slit part 4. It is preferably formed at an angle. Such a gentle angle varies depending on the thickness and diameter of the tube and the characteristics of the material composing the tube. Normally, if it exceeds 30 degrees, it is difficult to deform the tube 2 into the above-mentioned one-letter shape. If the angle is less than 10 degrees, the length of the tube inlet part 3 needs to be remarkably increased in order to exert the function of the tube entrance part 3. More preferably, it is 20 ⁇ 5 degrees, particularly about 20 degrees and its vicinity.
- the tube pulling portion 3 has an angular force of about 0 degree, and the tube 2 is deformed into a “ ⁇ ” shape. It is difficult to slide the tube from section 3 to slit section 4.
- the tube 2 is in a letter shape. The tube 2 is flat without leaving a part of the opening of the tube 2 or leaving the opening at all. Refers to a modified version.
- the tube clamped by the slit portion 4 only on one side of the boundary between the tube inlet portion 3 and the slit portion 4 is difficult to slide into the through hole.
- a stopper portion 5 for applying id resistance is formed.
- the stopper portion 5 is, for example, a clamp corresponding to a clamp before the stopper portion 5 of the present embodiment is not formed, and the inner surface of the tube insertion portion 3 on the side where the stopper portion 5 is formed is connected to the stopper portion 5. Extend from the inner surface of the tube inlet 3 on the side where the tube is not formed to the slit 4 side, and form a stepped or inclined step at the boundary between the slit 4 and the tube inlet 3 be able to.
- the stopper portion 5 can be provided while maintaining an appropriate slit portion width in order to sandwich a tube that excessively narrows the slit portion width.
- the clamp according to this embodiment forms the stopper portion 5 as described above, so that an appropriate slide of the tube from the tube insertion portion 3 to the slit portion 4 is maintained while maintaining a predetermined slit portion width.
- the stopper that prevents the tube from sliding from the slit section 4 to the tube insertion section 3 is improved, and the tube can be prevented from opening unexpectedly. be able to.
- the clamp of this embodiment at least a part of the surface of the tube inlet 3 and Z or the slit 4 is treated with a lubricant, or the tube inlet 3 and the slit 4 are configured.
- a lubricant By kneading the lubricant into the material, the slide from the through hole 1 of the tube 2 to the slit portion 4 can be facilitated.
- the plate clamp of this embodiment has the stopper portion 5 as described above. By forming it, we were able to solve this problem.
- the clamp of the present invention can improve the lubricity of the clamp itself when clamping a tube with good lubricity, for example, a tube lubricated on the surface or a tube kneaded with a lubricant.
- the stopper portion 5 can provide a stopper function that prevents the tube from sliding from the slit portion 4 to the tube insertion portion 3.
- the stopper portion 5 is provided only on one side, and this can be achieved when the stopper portion 5 is provided on both sides of the boundary between the tube inlet portion 3 and the slit portion 4.
- the tube inlet from the slit 4 is reversed.
- the stopper property that prevents the tube from sliding to 3 is improved, and the tube can be prevented from being opened unexpectedly.
