Description
Technical Field
The utility model relates to a reinforced plate type chain, and belongs to the field of chains.
Background
Chains, generally metallic links or rings, are used for mechanical transmission, traction, links for obstructing traffic passages (for example in streets, rivers or harbour entrances), chains for mechanical transmission, and are of various types, a single-strand chain being a common one of the most diverse types.
The plate type chain is a common transmission device, can reduce friction force, is usually used in places with larger power and slower speed, and is particularly suitable for corrosion resistance, cleaning or fields with strict requirements on certain chemicals and high and low temperature occasions.
But current plate-type chain simple structure, the condition such as the mounting between the connecting piece appears becoming flexible easily after long-term the use, causes the condition such as chain wearing and tearing or fracture, influences work efficiency, and current plate-type chain is also comparatively troublesome in the maintenance. Therefore, the reinforced plate type chain with good firmness and convenient use and maintenance is provided.
Disclosure of Invention
The utility model aims to overcome the defects and provide a reinforced plate type chain which is simple in structure, firm in fixation and long in service life.
The purpose of the utility model is achieved by the following technical scheme: the utility model provides a reinforced plate type chain, it comprises the outer joint piece and the inside chain of both sides, and wherein inside chain is formed by two row at least chain piece parallel connection, and wherein odd number row chain and the parallel alternate connection of even number row chain left and right sides head and the tail, all seted up the through-hole on outer joint piece, odd number row chain, the even number row chain, alternate a connecting axle in the through-hole, the length of this connecting axle is greater than the length between two outer joint pieces to being equipped with fixing device in the part that exposes, this fixing device fixes on the outer joint piece of both sides, still be equipped with linking bridge on the outer joint piece.
Preferably, the method comprises the following steps: the fixing device is composed of a nut and a screw, threads are arranged in the inner side through hole and on the outer side shaft wall of the exposed part of the connecting shaft, the nut is fixed with the threads on the outer side shaft wall, the screw is fixed with the threads on the inner side through hole, a screw head is arranged at one end, far away from the connecting shaft, of the screw, the width of the screw head is larger than that of the nut, the screw penetrates through the nut and then is clamped on the nut or is arranged in parallel with the nut, and a cross or a straight groove is further formed in the screw head.
Preferably, the method comprises the following steps: the connecting support is arranged above the outer connecting sheet and extends towards the left side and the right side of the outer connecting sheet respectively to form an L-shaped support perpendicular to the outer connecting sheet, and the support is provided with a connecting through hole.
The utility model can be maintained conveniently through the cross or straight groove arranged on the screw head, and the L-shaped bracket can ensure that the utility model is fixed firmly and is not easy to shake in working.
