[Industrial applications]

 The fitting type press fitting according to the present invention is applied to a place where a liner, that is, rubber, resin, iron plate or the like having strong abrasion resistance is attached to a place where the chute, hopper, etc. are worn and cannot be reached. It is used to attach the liner.

[0002] In the detailed description of the press-fitting metal fitting according to the present invention and the drawings for the embodiments thereof, a liner made of rubber, resin, iron plate or the like having a strong abrasion resistance is used for a chute, a hopper or the like to be worn. In the case of attaching the liner, "attachment body" means the body of the chute, hopper, etc. to which the liner is attached.

[0003]

[Prior art]

 When attaching a liner to the body of a chute, hopper, etc., it is not possible to make holes in two or more places that are out of reach, put bolts in the holes and tighten nuts, so There was a drawback that the liner was easily loosened by the force of. This is because, in the conventional technology, a hole of an appropriate size is made in the mounting body in order to simply hook it in a place where it cannot be reached, and a hooking tool with a liner is simply hooked on it. There was a danger that the liner could easily come off if a force was applied to the liner laterally or downwardly by an object coming into the hopper. As a result, the liner was absorbed into the object and was lost. Therefore, it was necessary to eliminate the uneconomical loss of the liner.

[0004]

[Problems to be solved by the device]

 The present invention is proposed for a means for attaching a liner to a wear-prone part such as a chute or a hopper, and in particular, a method of inserting a bolt provided in the liner and tightening with a nut is not taken. It seeks to develop a liner that can be firmly secured to its mounting part, such as is used when the liner must be installed in a tight, inaccessible area, and also with hammers for shorts or shorts. It is intended that the part where the liner is attached be detached from the main body such as the hopper.

[0005]

[Means for Solving the Problems]

 The fitting type press fitting according to the present invention is provided with a slide jig adapted to slide inside the hook fitting provided on the liner, and the slide jig is formed in a wedge shape, and a protrusion is provided at a substantially right angle on the upper part thereof. Attach the liner by hooking the protruding part on the edge of the hole made in the wearable part of the mounting body, sandwiching the slide jig between the mounting body and the hook metal fitting, and pressing the liner downward. It is intended to be strongly attached to the main body.

More specifically, in order to strongly fix the liner to be attached to the chute, the hopper, etc., the base of the hooking metal having its tip curved downward is provided on the liner, and the hooking base is provided. A wedge-shaped slide jig that slides inside the metal fitting is provided, the lower part of the slide jig has a thickness, and the upper part has a wedge-shaped taper that is slightly thin. At the upper part of the wedge-shaped taper, a protrusion bent almost at a right angle is provided. Insert the tip open below the hook metal fitting into the hole opened in the mounting body and hang the protruding part of the slide jig on the edge of the hole to slide between the hook metal fitting and the mounting body. Since the tool is clamped, the liner is pushed down so that it slides upward and is pressed between the mounting body and the hook.

In order to attach the slide jig to the portion of the hook metal fitting, a long bolt hole is provided in the hook metal fitting, and a captive bolt is attached to the bolt hole to prevent the bolt from falling off. The tip was provided on the slide jig. The slide jig can be reused by removing the liner without falling off.

In order to reuse the slide jig, instead of a bolt for attaching the slide jig to the hook metal fitting, notches are provided on both sides of the hook metal fitting to narrow the hook metal fitting, and the hook metal fitting falls off there. A band for prevention was provided, and both ends of the band were provided on the side surfaces of the slide metal fitting so that the slide jig could be mounted so as to slide inside the hook metal fitting.

[0009]

[Action]

 The function of the fitting type press fitting according to the present invention is that there is a slide jig inside the hook fitting provided on the liner, so that the slide fits on the edge of the hole made in the wear-prone part of the mounting body such as chute and hopper. When the protrusion on the top of the jig was hooked and the liner was pushed down, the slide jig was slid upward by pushing down the liner. By this sliding, the wedge-shaped slide jig is sandwiched between the mounting body and the hooking metal fitting to firmly fix the liner to the mounting body.

To explain this action more concretely, a hole is made in a wear part of a chute, a hopper, etc., and a slide jig of a fitting type press fitting with a liner attached is hung in the hole, and the liner is moved downward. When it is pushed down, the protruding part of the wedge-shaped slide jig with taper hangs on the edge of the hole and goes up, so that the slide jig comes into close contact with the angled hooking metal fitting and the hooking metal fitting and the mounting body. Since a slide jig is sandwiched between and pressed, it acts to firmly attach and fix the liner to the main body. At the time of removal, if the liner is pushed upward from below, a gap will be created between the slide jig and the angled hooking metal, and it will come off.

In order to prevent the slide jig from being detached so that the slide jig is attached to the portion of the hooking metal fitting, the slide jig is provided with the tip of the drop-prevention bolt having a head that passes through the bolt hole. The slide jig can be reused without falling off when the liner is attached or detached. The long bolt holes formed in the hook metal have the effect of vertically sliding the slide jig.

[0012] In order to reuse the slide jig, instead of the bolts for attaching the slide jig to the hook metal fitting, both ends of the fall prevention band provided in the notches provided on both sides of the hook metal fitting are attached to the slide metal fitting. It was provided on the side surface so that the slide jig could be attached so as to slide up and down.
