Abstract

The utility model relates to a structure for achieving expansion force regulation of relative mechanisms through increasing or decreasing milky substances in various engineering mechanical structural designs. The structure comprises a screw plug, a spring, a steel ball, a washer, a main body, an ejector pin, a nut, an oil cup, an O-shaped ring, a rotary joint, and the like, wherein a threaded end of the main body is screwed in a connecting hole of a container, and the direction of the oil cup is regulated through the nut and the rotary joint. The structure is filled with the milky substances through the oil cup through the adoption of a proper tool, and the substances push away the steel ball and enter the container (oil cylinder) until the added volume meet the requirement. When the expansion force is overlarge because of the expansion of the volume of the structure caused by too much filling or the change of the ambient temperature, a lock nut is firstly loosened, the ejector pin is screwed in the structure, and the steel body is pushed away; and then redundant milky substances flow in a reverse direction along the entered channel under the action of the expansion force, and flow out of the structure from clearance between a lug boss at the other end of the ejector pin and the rotary joint, and a T-shaped channel reserved at the threaded end of the ejector pin.

Description

Novel milky substance charging point

Technical field

The utility model relates to a kind of charging point of construction machinery and equipment, particularly a kind of novel milky substance charging point.

Background technology

At present, various mechanical equipment swelling devices are made up of part portions such as spring, oil cylinder, oil nozzles mostly.This apparatus structure is simple, maintenance is easy, easy to operate, is extensively used and should be particularly useful for containing the product of crawler travel structure type in the design of various construction machinery and equipment tension mechanisms.

Owing to contain of the increase of crawler travel construction machine equipment along with volume, weight, crawler belt also can increase the applied loading of its swelling device thereupon suddenly, the impact load that in the equipment walking process, is produced particularly, be unable to estimate at all, common lubricating cup can't be kept out at all and be filled the pressure load that grease passes over, in the mechanism design process, engineering staff often between grease container and lubricating cup, are provided with the different oil nozzle parts of structure.These parts play in time and carry, replenish grease to container, and the impact load that fundamentally prevents the swelling device motion has well been protected lubricating cup to the destructive effect that lubricating cup produces.Find that in long-term use these parts are when carrying, replenishing grease and providing convenience in container, when ambient temperature changes, or oil addition too much causes expanding force excessive and must adjust the time, also stays at one's wit's end sorry.

The utility model content

The purpose of this utility model provides a kind of simple in structure, reliable and practical, is adapted to dissimilar dependence milky substances and carries out the occasion that expanding force is adjusted, and can be widely used in the various novel milky substance charging points that the track unit expanding force is adjusted that contain.

The purpose of this utility model is achieved in that this charging point comprises screw plug, container, spring, steel ball, packing ring, main body, push rod, nut, lubricating cup, O shape circle I, black nut, O shape circle II, steel wire and swivel joint, screw plug is screwed in the hole of threaded end of main body, this hole is a through hole, and spring and steel ball are arranged in the hole; One end of main body is installed on the container, between container and main body packing ring is arranged, and the other end of main body is connected with swivel joint by nut, and O shape circle II and steel wire are arranged between main body and swivel joint bonded assembly end face; On the sidewall of the other end of swivel joint, be connected with lubricating cup, be connected with push rod in the heart in swivel joint, be connected with O shape circle I between the rear portion of push rod and the swivel joint, be connected with black nut in the end of push rod.

The thread end of main body is screwed in the part, and the direction of adjusting lubricating cup by nut, swivel joint is also fastening.Use special-purpose instrument in this charging point, to carry milky substance by lubricating cup, increase along with this material volume, enter the space of push rod left end by the semicircle orifice of push rod cylinder, then back down the spring-loaded steel ball, enter the container (oil cylinder) of milky substance from the centre hole of screw plug, till the volume that adds meets the requirements.When the filling milky substance too much or because of variation of ambient temperature causes its cubic expansion, when causing expanding force excessive, at first unclamping black nut is screwed into push rod and pushes steel ball open, the milky substance that this moment is unnecessary, under the effect of its expanding force along the passage counter-flow that enters, from the gap between push rod other end boss and the swivel joint, and the "T"-shaped passage that the push rod thread end leaves flows out the external of this charging point.In case when the expanding force adjustment met the requirements, the outward turning push rod cut off the passage that leaks, keeps sealing property to another end position immediately, screws black nut immediately.

Push rod in the described structure, the left surface of left end maximum gauge cylinder (having semicircle orifice) is to the length of its high order end, support end face can reach the limit of the position to this cylinder left surface size greater than steel ball in the main body, guarantee that the sealing band between steel ball and the main body is opened, when the structure of push rod left end is also guaranteed to be screwed into limit size, draining passage unblocked; Sealing requirements when the O shape circle that its right-hand member is installed should guarantee to annotate milky substance with the end face of swivel.

During installation, at first steel ball, spring are put into the hole of main body small end and screwed with screw plug; I is installed in the groove on swivel joint boss inclined-plane O shape circle, cover upper nut, insertion steel wire; II puts in the groove of push rod thread end O shape circle, again the top

The thread end of bar inserts and is tightened in together from the endoporus of swivel joint boss, installs, tightens black nut simultaneously.Again the non-threaded end of push rod is inserted in the main body, finish being threaded of two inter-modules simultaneously; The cover upper gasket also screws in the threaded portion that main body exposes fully in the connecting bore of container and tightens; Adjust the direction of swivel joint and screw nut; Lubricating cup is installed at last.

Advantage of the present utility model, solve existing product to the filling quantity of milky substance within the specific limits can't regulated at will a difficult problem, the exposed junction of push rod is provided with screw thread for connection, uses corresponding flexible pipe can realize the recovery fully of oil substances, avoids environmental pollution.
