Abstract
A filler cap tension device is used on a filler cap of a gearbox of a loader, and comprises an end cover, a gasket, a rubber cover, a handle, a flange and a cotter, wherein the rubber cover and the flange are fixed together and then are arranged in the end cover, the handle is connected with the flange by threads, and the end part of the handle is limited by the cotter. After being arranged in an oil filler pipe, the filler cap is pressed, then the handle of the filler cap is rotated, and as the handle is connected with the flange by threads, when the flange is upwards screwed in the rubber cover, the diameter of the rubber cover is increased, so that tight match can be formed between the rubber cover and the oil filler pipe, therefore, the falling down of the filler cap or the entrance of dust during the operation of the loader can be avoided, and the operational reliability of the filler cap of the gearbox of the loader can be greatly improved.
Description
Technical field:
The utility model is a kind of on the loading machine gearbox filler cap, realizes the device of automatic tension sealing.
Background technique
Mostly the gearbox filler cap of present domestic loader is the serum cap structure; Be fixed on the oil filling pipe with chain; Because in use wearing and tearing of filler cap and aging; Gap between filler cap and the oil filling pipe is increased, cause filler cap when the loader operation, to vibrate and drop or the dust entering, gearbox fluid is polluted.
Summary of the invention
The purpose of the utility model is exactly on the loading machine gearbox filler cap, designs a kind of device of automatic tension sealing, avoids filler cap when the loader operation, to vibrate and drops or the dust entering, improves the operational safety of filler cap greatly.
The purpose of the utility model is achieved in that this device is made up of end cap, packing ring, handle, rubber sleeve, flange, cotter pin; Rubber sleeve and flange are fixed together; Pack in the end cap, handle and flange are through being threaded, and handle end is spacing with a cotter pin.After filler cap is packed oil filling pipe into; Push filler cap, rotate the filler cap handle then, because handle and flange are to be threaded; This moment the flange precession compressing rubber cover that will make progress; The diameter of rubber sleeve will increase, and make to form between rubber sleeve and the oil filling pipe to closely cooperate, and drop or the dust entering thereby avoided filler cap when the loader operation, to vibrate.
The utility model has the advantages that: 1, with respect on filler cap, preventing the mode that drops with chain, native system utilizes the mode of rubber sleeve tensioner to avoid dropping of filler cap, and is simple in structure, and reliability is high.2, native system utilizes the mode of rubber sleeve tensioner can realize the gap compensation of rubber sleeve after wearing and tearing, and sealing is better.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Among the figure: 1 end cap, 2 packing rings, 3 handles, 4 rubber sleeves, 5 flanges, 6 cotter pins, 7 oil filling pipes.
Embodiment
Embodiment, this device is made up of end cap 1, packing ring 2, handle 3, rubber sleeve 4, flange 5, cotter pin 6, oil filling pipe 7.Rubber sleeve 4 is fixed together with flange 5, and in the end cap 1 of packing into, handle 3 and flange 5 are through being threaded, and handle end is spacing with a cotter pin 6.
When the operator when filler cap is installed, filler cap is packed into behind the oil filling pipe 7, push filler cap; Rotate filler cap handle 3 then; Because handle 3 is to be threaded with flange 5, this moment the flange 5 precession compressing rubber cover 4 that will make progress, the diameter of rubber sleeve 4 will increase; Make to form between rubber sleeve 4 and the oil filling pipe 7 to closely cooperate, drop or the dust entering thereby avoided filler cap when the loader operation, to vibrate.The utility model can improve the operational safety of loading machine gearbox filler cap greatly.
