In being below above-described embodiment, the specific chi of the specific making type selecting processes of all parts, method and each part
Very little specification, more detailed description is done with specific dimensions to the grease gun base of the program.
Double-deck larynx garter spring：Double-deck larynx garter spring is larynx garter spring common on the market, and the present invention uses the double-deck larynx hoops of φ 40-50
Ring, bolt, the screw rod simply shunk unloads progress and is transformed into contraction pull bar, wherein two pairs of tie-bars are also from new design,
Hole inside first tie-bar is bigger than normal, be it is movable, it is not threaded；And the second tie-bar is internally screw-threaded, with shrinking pull bar
External screw-thread is matched, and realizes threaded connection.The double-deck larynx garter spring is made using zinc-plated steel bar, and cost is relatively low, can contact factory
Family carries out making batch production.
Shrink pull bar：The contraction pull bar is by the substitute of the bolt above double-deck larynx garter spring, screw rod redesign.The receipts
Contracting pull bar is designed as the hexagon socket head cap screw that a length is 50mm.The length for shrinking pull bar is set according to the size of butter gun main body
Meter, can be 40~60mm, or other sizes, the size cannot function as limiting factor (s), can be according to specific change.
Fixed card：Fixed card is made up of the collar, card, U-shaped anti-shake card.Wherein the collar is formed with steel casting
The collar, external diameter and the first sample for shrinking pull bar, and internal diameter is just greater than the screw rod for shrinking pull bar, shrinking pull bar can be inside the collar
Activity；Card is formed by the thick steel plate compactings of 1mm, there is an a diameter of 3.6mm eyelet, the upper and lower ends and set of card above
Ring is welded；U-shaped anti-shake card is also to be formed by the thick steel plate compactings of 1mm, and deep small of a 1mm is then opened in its bottom
Mouthful, then osculum is stuck on card, finally by being weldingly fixed on card.
Stake body：Including base steel plate, split bolt, rubber mat.Base steel plate is by steel plate compacting thick two panels 2mm
Into being then fixed by 4 split bolts.Both combinations provide sturdy base to grease gun.Rubber mat is by rubber
Glue industry is made, and it is square, and middle is fluted, and the groove is used to stretch on the pin of base steel plate to come into, and then
Anti-skidding, damping foot pad is provided to base support.
Fixing card bar：Fixing card bar is made up of fixed plate and U-shaped fixing card, and fixed plate is divided into left fixed plate and the right side is solid
Fixed board, both are symmetrical, are all to be formed by thick 2mm steel plate compacting and bending, there are 3 holes its upper end, and there are 2 holes lower end,
This some holes contributes to solid seat rivet and is fixed on base steel plate；U-shaped fixing card be also by steel plate compacting thick 2mm and
Bending is formed, then by left and right two panels fixed plate（There is the gap that can just insert fixed card centre）Weld together, it is led
Act on is to support above-mentioned fixed card.
Rise arm spring：That scroll spring is fabricated to by elastic metallic, its one end is stuck on base steel plate, the other end reach as
Position shown in figure, when the position is that grease gun is installed to base support, the lower section of its handle.Rise arm spring and pass through spring bolt
It is fixed on base steel plate.The handle that arm spring is mainly used in lifting grease gun is risen, that is, when removing driving grease gun with pin,
When unclamping pin, the handle of grease gun is lifted by spring force, prepared for injection next time butter.
Snap crotch：By the thick steel plate compactings of 2mm, the crotch of L-shaped is formed, it is fixed on base steel plate by rivet.
The crotch can be rotated around rivet.It, which is mainly used in pinning, rises arm spring, that is, when without using grease gun base,
Just a liter arm spring is caught on snap crotch, does not allow it to tilt.
Above-mentioned all sizes and structure cannot function as unique specification to limit the part of this programme, the portion of this programme
Part structure and size are set according to the size in place and the size of grease gun, can make difference according to different places
The base of specification, or changed accordingly.
The specific installation of program grease gun base and the course of work are as follows：
The first step, fixed double-deck larynx garter spring：
First have to unclamp on the contraction pull bar above double-deck larynx garter spring, double-deck larynx garter spring is set on the ring of grease gun, and insertion is shunk
Pull bar and fixed card carry out contraction fixation；
Second step, base support are ready to, mounting seat support, and a liter arm spring is caught on snap crotch.
3rd step, preparation grease gun, butter, and vent gas are filled by the grease gun for fixing double-deck larynx garter spring, and
Oiling is attempted, butter is extruded；
4th step, installation：Grease gun with double-deck larynx garter spring is installed on base support, snap crotch is unclamped and allows a liter arm bullet
Spring lifts the handle of grease gun automatically.
5th step, use：Grease gun and its base are placed on smooth ground, with gun nozzle of grease gun is held by, used
Pin goes to step on the handle of grease gun, steps on and then unclamps, circulation is gone down, until completing whole oiling process.
Grease gun base of the present invention, it can repack conventional hand grease gun into foot-operated butter rifle.
Its feature installs facility, and repacking is simple, disassembled, portable.The grease gun base allows general hand grease gun, can keep using
Hand-drive oiling, can drive oiling with pin again.The present invention can be cost-effective, and can facilitate and use.
Annexation, treating method between above-mentioned structure mounting means, part are merely possible to for an example
It is bright, it is impossible to think only to protect a described scheme, it is every to needing such grease gun in the case of can with reference to this programme side
Formula method.
Those skilled in the art can make various modifications to described specific embodiment
Or supplement or substituted using similar mode, but spirit without departing from the present invention or surmount appended claims and determine
The scope of justice.
