Abstract

[PROBLEMS] To reliably prevent leakage without twisting, cracking or detachment even when a high pressure hydraulic load is applied in an integrated connection of hoses that pumps waste water or the like with a hose connection clamp. Provide a hose coupling fastener without any. A hose coupling fastener for fastening a hose to a coupling portion, which is provided with a plurality of projections and depressions on the inside of a main body in several rows, and an insertion groove having an odd projection on one side of the main body. The even-numbered groove projection 3 that meshes with one side is engaged, and the hose is tightened. Also, a number of anti-distortion protrusions 12 are provided on the outer periphery, and even if the tightening bolt 6 is tightened strongly, twisting, cracking, and deformation do not occur. The structure. [Selection] Figure 3

Description

  The present invention relates to a hose coupling fastener that makes it easy to attach and detach an extended hose when draining with a pump, and that does not break off even in high-pressure drainage.

  In order to carry out the conventional hose connection, a wire is wound and tightened with pliers or a metal band. In addition, there are many things that clip the band or tighten it with a spring spring, but there are problems such as troublesome attachment and breakage.

Therefore, there were the following problems.
The complicated workability of tightening multiple points with a wire, and the hose breaks because the hose is crimped in a linear fashion. Conventional devices have not been able to obtain adhesion performance that can withstand high water pressure, and have poor workability at the site. The present invention has been made to solve these problems.

  In view of this, the present invention has a wide face, wide contact, fitting protrusions, and tightening bolts into bolt grooves and tightening firmly with nuts. The looseness and wrinkles of the hose caused by tightening can be adjusted by the concave and convex grooves provided on the inner surface, and the adhesion to the hose is enhanced and the high pressure drainage is not detached and damaged.

  Therefore, the hose coupling fastener of the present invention can be mounted in a short time with only a nut tightening tool without requiring skill in the mounting operation in actual use. Furthermore, it can be easily removed and reused, and the cost is low.

Embodiments of the present invention will be described below.
The main body 1 has semicircular arc-shaped main bodies 1 on both sides with the support pin 2 as a starting point. The insertion protrusions 3 and the insertion grooves 4 at both ends are engaged with each other, the fastening bolts 6 are inserted into the bolt grooves 5 and tightened with the nuts 9. The pressing plate 11 is tightened firmly enough to be pushed in.

(1) In order to protect the hose from being damaged by tightening pressure, spray rubber or soft resin on the inner surface of the semicircular arc.
(2) Tighten the pressing plate to tighten it.
(3) Several semicircular convex portions are provided on the semicircular arc-shaped appearance surface to prevent distortion, cracking, and distortion of the main body.

  Drainage work is a necessary requirement for excavation and burial work such as subway construction, building construction work, underground equipment work, river work, and agriculture-related work, so the necessity for use is great.

  It is an expanded view of the inner surface state of the main body concerning this invention.   It is an external view of the outer surface of a main body.   It is an expanded view at the time of use which is going to attach to the connection part of a hose.

Claims (4)

  A hose coupling tightening tool that does not leak water or remove the hose by fitting a fitting groove with an odd number of protrusions on one side of the main body, an even number of groove fittings that engage with one side, and fixing with a tightening bolt and nut.   The hose coupling fastener according to claim 1, wherein a groove on the inner surface of the main body is provided to adjust the slack and wrinkles of the coupling hose so as to ensure close contact.   The hose coupling fastener according to claim 1, wherein a pressing plate is provided in order to securely fix the tightening bolt when the bolt is inserted into the bolt groove and tightened with a nut.   In order to prevent cracking and distortion even if firmly tightened on the outer surface of the main body after turning the support pin and putting it in use, a certain number of semi-convex anti-distortion protrusions are provided for a reliable purpose. Hose coupling fastener made.
