Description

TRACTION ROPE HIDING APPARATUS OF PRESSURE PLATE FOR GREASE INJECTOR}

The present invention relates to a pulling line hiding device to hide the pulling line used during the pulling of the pressure plate after the grease filling operation of the grease injector.

The grease injector, which injects grease to prevent wear on the operating parts of various machinery, can be largely divided into a mobile manual grease injector and a fixed automatic grease injector.

In other words, in the case of the mobile manual grease injector, the grease in the case is lubricated by the piston by the manual pumping lever while the pressurized plate, which gives the elastic force of the compression spring, is pressurized to pressurize the grease filled in the case. In the case of the fixed automatic grease injector, the grease in the case is operated by the piston operation by the motor while the grease filled in the case is pressurized by the pressure plate that gives the elastic spring force of the compression spring. It is configured to be injected into the lubrication portion of the.

Therefore, in order to fill the grease in the case away from the specific injection means of the grease, these kinds of grease injectors must provide a means for forcibly retracting and fixing the pressure plate given the elasticity of the compression spring. Repeated use is possible.

The initial grease injector was fixed by connecting rod-type pull rods with handles to press plates that are elastically installed with compression springs in the case, such as Utility Model Registration No. 20-0320291 and Utility Model Registration No. 20-0456610. It is configured to fill grease in the case in the retracted state of.

However, the grease injector having a rod pull rod has a long length in the case of a mobile manual grease injector because the rod pull rod protrudes longer to the rear of the case as the amount of grease is filled. It is impossible to enter into the curved space of the product, which leads to many limitations in use, as well as the rod-shaped pull rod that protrudes long in the process of grease injection by the operation of the manual operation lever. In the case of automatic grease injector, the rod-shaped pull rod protruding long behind the case not only looks ugly and occupies a lot of installation space, but also obstructs the work of workers passing by.

And recently, in order to solve the problems of the grease injector having a rod-shaped pull rod, pull lines on the pressure plate elastically installed with a compression spring in the case, such as Utility Model Registration No. 20-0458487 and Utility Model Registration No. 20-0355792 By pulling the pull line by using the handle to retract the pressure plate.

However, the grease injector with a long pull string has a long pulling line from the case as the amount of grease in the case increases, so the mobile manual grease injector is inconvenient for use and into the mechanism requiring grease injection. When entering to allow grease injection, long stretched strings may be caught in the rotating body, causing safety accidents. In addition, it takes up a lot of installation space, and there are many problems such as a pull line around the rotating body, which may cause a safety accident.

It is an object of the present invention to provide a pressure plate pull line hiding device of a grease injector which can use a pulling line as a pulling means for retracting the pressure plate in the case and hide the pulling line in the case after pulling the pressure plate.

Pressure plate pull line hiding device of the present invention grease injector for achieving the above object is connected to the pressure plate to form a cap to open and close the hole at the end of the pull line projecting to the outside through the through hole in the case through the pull line after use Inserted through the inner space portion of the case and characterized in that configured to block the through-hole with a cap.

The present invention uses the pull string 20 as a means for retracting the pressure plate 26 in the case 20 when the grease is filled, opening and closing the through hole 22 of the case 20 at the end of the pull string 28 Forming the cap 32 to retract the pressure plate 26 by pulling the pull string 28 using the handle 30 to fill the grease and then pull the pull string 28 through the hole 22 through the case 20 By inserting the inside to block the through-hole 22 by the cap 32, there is no fear that the pull string 28 is long to hang to the outside to maintain a beautiful appearance as well as the use due to the pull string (28) It is possible to eliminate the inconvenience and prevent the safety accidents such as being caught in the rotating body of the machine that requires the injection of grease by the long pulling string 28 extending from the case 20 during the grease injection operation. In the case of a fixed automatic grease injector (52), It will be yeojul that is effective such that the number of lines allows increasing the space utilization.
