CN201779373U - Straight joint for forklift - Google Patents

Abstract

The utility model discloses a straight joint for a forklift, comprising a joint. The straight joint is characterized in that an inner bore of the joint is a straight bore, the upper part of the joint is provided with an inlet, the lower part of the joint is provided with an outlet, two ends of the joint are provided with external threads, the middle part of the joint is provided with an annular bulge, and a gasket is arranged between the bulge and the external threads at the lower part. The straight joint can improve the stability of a pipeline, the straight pipes are good in connection safety, the service life is prolonged, the structure is simple and the installation and replacement are more convenient.

Description

A kind of fork truck straight coupling

Technical field

The utility model belongs to a kind of connection set, specifically is a kind of fork truck straight coupling.

Background technique

In the structural design of fork truck, need use straight coupling, using basically on existing fork truck all is straight connector, screw-thread fit is taked at two, and expanding with heat and contract with cold appears under high temperature or rugged environment in sealer covering so easily, there is less clearance, not only is easy to generate the seepage phenomenon, and under long-term friction, thread abrasion is very fast, thereby reduced the working life of joint, needed often to change, increased operating cost, reduced operational benefit, and installed and keeped in repair all inconvenient.

The model utility content

The purpose of this utility model provides a kind of fork truck straight coupling, has that Security is good, the characteristics of long service life, and simple in structure, and it is all comparatively convenient to install, change.

The technical solution of the utility model is as follows:

A kind of fork truck straight coupling includes joint, it is characterized in that described joint endoporus is a straight hole, and top is import, and the bottom is outlet, and there is outside thread at the joint two ends, and there is annular protrusion at the joint middle part, between projection and lower external thread packing ring is arranged.

The utility model adopts the middle part projection, can strengthen support effect, has improved the stability of pipeline, and thread bottom is provided with packing ring outside simultaneously, can increase the sealing between joint and external pipe, has improved the Security and the fluency of oil circuit output; Global design is a cast structure, and is not yielding, can increase the service life, thereby save maintenance expenses, also reduced replacement cost, improved productivity effect, and overall structure is simple, installs and uses all very convenient.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

A kind of fork truck straight coupling includes joint 1, it is characterized in that described joint 1 endoporus is a straight hole, and top is import 2, and the bottom is outlet 3, and there is outside thread 4 at joint 1 two ends, and there is annular protrusion 5 at joint 1 middle part, and projection 5 and 4 of lower external thread have packing ring 6.

Claims (1)

1. a fork truck straight coupling includes joint, it is characterized in that described joint endoporus is a straight hole, and top is import, and the bottom is outlet, and there is outside thread at the joint two ends, and there is annular protrusion at the joint middle part, between projection and lower external thread packing ring is arranged.
