SU1037013A1 - Lubricant gun - Google Patents

Description

The invention relates to mechanical engineering, and in particular to devices for servicing machines and assemblies designed to supply lubricant to lubrication points. 5

Lubricating guns are known that contain a tip holding a grease fitting, an injection tube, a housing in which a spring-loaded rod with a check valve and a channel are installed: for supplying lubricant from the compressor to the discharge tube, and a handle pivotally mounted on the housing., The lubricant is supplied by pressing handles [1].

However, the presence of a valve and a hinge system complicates the design and reduces the reliability of the lubricating gun. 20

A lubricating gun is also known, which contains a nozzle with a discharge tube that fixes the grease fitting, and a locking device in the form of a spring-loaded spool with a cap 25 for supplying lubricant, the spool connected to the discharge tube having the possibility of axial movement in the housing with a handle [2 ]. 'thirty

The disadvantages of the known lubrication gun are that during the lubrication cycle a constant manual force is necessary on the handle, which is difficult to carry out in hard-to-reach places, and also that visual monitoring of the lubrication process is complicated.

The aim of the invention is to improve the quality of lubrication operations.

This goal is achieved by the fact that in a lubricating gun, including a tip, a press-fixing nipple, an injection tube, a locking device made in the form of a spring-loaded spool with a channel for supplying lubricant connected to the injection tube and having axial movement in the housing bore, the spool and the body bore is made stepwise, in the spool there is an additional channel connected to the channel for the subtype of lubricant and with a large stage of the body bore. ,

VNIIIPI Order 5977/38

In addition, the spool is equipped with a retractable shield ..

¹ . The drawing shows the proposed device.

A lubricating gun consists of a tip 1, an injection tube 2, nuts 3. of the housing 4 with a stepped sleeve 5, and a stepped spool 6 with a channel 7 located therein.

p '* by an additional channel 8 and a rod-pointer 9> the spool 6 is spring-loaded with a spring 10, of the handle 1 1 with a channel for supplying lubricant 12 from the supercharger.

The gun works as follows. " A locking tip is connected to the grease nipple of the lubricated point ,! and the handle 11 is pressed. Under the action of manual force, the discharge pipe 2 with the spool 6 moves to the right from the initial position, compressing the spring 10, while in the final position the channel / spool 6 is combined with the channel 12 and the lubricant along the channel 12, channel 7 the tube 2, the tip 1 enters the consumer. At the same time, the lubricant through the additional channel 8 enters the vacant, annular cavity of the sleeve 5 and the pressure of the lubricant spool 6 is fixed in the right (final position).

The lubrication cycle occurs without the need for far / tero application of manual force.

After the end of the cycle, when the tip 1 of the gun and the grease gun is unlocked by manual force and the action of the spring 10, the spool 6 moves to the left, blocking the supply of lubricant 40 to the channel 7 from the supercharger and already under the action of the spring 10, the spool 6 returns to its original position. The rod-pointer 9. having the ability to exit from the housing to the outside, allows you to visually observe the operation of the lubricating gun.

The execution of the spool and bore of the housing stepwise, as well as the connection of the annular piston cavity with an axial channel, provides an increase in the quality of lubrication operations.

The presence of a movable rod allows you to visually monitor the operation of the lubricating gun, in contrast to the well-known and basic sample that does not contain control devices.
