Description

A kind of pneumatic grease gun

Technical field

The utility model relates to a kind of grease gun, particularly a kind of pneumatic grease gun with feed function.

Background technique

People's standard of living day by day improves now, and is also more and more high for quality, the performance demands of general daily instrument, and the user also is willing to be intended to the more expense of cost on the new function instrument.

Present pneumatic grease gun kind is very various, and still, the restriction owing in operation, the moulding can not fast, easily pour into a large amount of butter, and it is very inconvenient to operate; Can fast, easily pour into a large amount of butter, just become the Consumer and primarily select.

The internal structure of traditional pneumatic grease gun as shown in Figure 1, it is a sheathed closed piston 11, a Returnning spring 12 in air chamber 10, and cooperates a trigger 13 that can communicate with air chamber 10 when garnishment not to combine.Still there are deficiency in its practicability of the grease gun of this structure and operability, and reason is as follows:

After the each button of this pneumatic grease gun drew trigger 13, closed piston 11 was gone out butter is extruded, but the air of high pressure is then being filled at closed piston 11 rears, and after need person to be used decontroled trigger 13, the high-pressure air at closed piston 11 rears was just disengaged; Button draws trigger 13 so if the user need pour into butter in a large number the time, just needs ceaselessly, and operation is trouble very.

Summary of the invention

The purpose of this utility model is at above-mentioned deficiency, proposes a kind of pneumatic grease gun, and it has the function of continuous feed, and the user need not detain again and again and draw trigger, and operation is very easy.

Pneumatic grease gun described in the utility model is provided with a piston and a Returnning spring in the air chamber between its body of a gun and the gun barrel, and is advanced to gun barrel by pressurized gas promotion piston, it is characterized in that:

Piston is that a slip is arranged at the disc in the air chamber, be provided with seal ring in all sides of disk, and be provided with the urgent part of corresponding gun barrel in disk one side, and on disk, be equipped with several corresponding through holes, and between several through holes, also be provided with some ventilative through holes and a groove;

Continuous firing mechanism is formed by reversing spring, preceding action disk, back action disk, pre-power spring and connecting rod, and wherein preceding action disk has several screws, and its screw is corresponding with several through holes on the action disk of back; Some connecting rods are the body of rod that two ends have screw thread, and one end screw lock is in several screws of preceding action disk, and the other end passes the through hole of back action disk again after passing several through holes of disk, and fastening by screw; Pre-power spring is set in the hollow slot of disk, and the top is formed between back action disk and the disk; Reverse spring one end top built in gun barrel week side.

The urgent part of above-mentioned piston can be a urgent bar, and is provided with one for compeling the through hole that bar wears in previous crops Moving plate central authorities.

The utility model utilizes one group of set on piston spring valve, is engaged in the reverse spring and the Returnning spring of air chamber front end, and spring valve is opened, and can be made piston reset once more, and percussion once again behind pressure accumulation.The utility model can be realized the function of continuous feed, allows the user need not to detain again and again and draws trigger, the easy to operate and practical effect of tool.

Embodiment

As shown in Figure 2, continuous firing mechanism 50 is arranged in the air chamber 22 between the body of a gun 20 and the rifle head 21, wherein:

Air chamber 22, it is a sealed space, be positioned at the inside of the grease gun body of a gun 20 and rifle head 21, in the body of a gun 20, be provided with an inlet hole 25 and may command pressurized gas source, on rifle head 21, then be provided with the gun barrel 24 that can supply butter to expel by the trigger 23 that inlet hole 25 enters;

Piston 30, be that a slip is arranged at the disc in the air chamber 22, be provided with seal ring 32 in disk 31 all sides, and be provided with the urgent bar 33 of corresponding gun barrel 24 in disk 31 1 sides, and on disk 31, be equipped with three corresponding through holes 34, and between three through holes 34, also be provided with some ventilative through holes 35 and a groove 36;

Returnning spring 40 is the spring of big external diameter, and the one end is located at rifle head 21, and the other end top is built in disk 31 places of piston 30;

Continuous firing mechanism 50, comprise and reverse spring 51, preceding action disk 52, back action disk 53, pre-power spring 54 and connecting rod 55 etc., wherein: preceding action disk 52 has three screws 521, screw 521 is corresponding with three through holes 531 of back on the action disk 53, is provided with one for compeling the through hole 522 that bar 33 wears in preceding action disk 52 central authorities; The two ends of three connecting rods 55 all have screw thread 551, and an end screw lock is in three screws 521 of preceding action disk 52, and connecting rod 55 the other ends pass the through hole 531 of back action disk 53 again after passing three through holes 34 of disk 31, and by screw 56 lockings; Pre-54 on power spring is located in the groove 36 between 31 3 through holes 34 of disk, and the top is built in 31 in back action disk 53 and disk; Reverse the gun barrel 24 all sides of 51 one end tops of spring built in rifle head 21.

As shown in Figure 3, as user before button does not draw trigger 23 as yet, 40 ejections of spring that are reset of the disk 31 of the piston 30 in the air chamber 22, and make disk 31 keep roof pressures on the inlet hole 25 of the body of a gun 20; The back action disk 53 of continuous firing mechanism 50 is understood pressurizeds and the pre-power springs 54 in the hollow slot 36 that is located at disk 31 is compressed, and the screw 56 of top built in the body of a gun 20 in will promote three connecting rods 55 slippage in the through hole 34 of the through hole 531 of back action disks 53 and disk 31, and action disk 52 is risen by disk 31 other side stays before the order, at this moment, the ventilative through hole 35 of several that wear on the disk 31 is by 53 sealings of back action disk.

As shown in Figure 4, after user's button draws trigger 23, may command pressurized gas source is entered by inlet hole 25, and pressurized gas will promote back action disk 53 fast, and make disk 31 in air chamber 22, move forward, 40 of Returnning springs are compressed the power of holding, compel bar 33 when entering gun barrel 24 butter being expelled up to disk 31 1 ends, the preceding action disk 52 of continuous firing mechanism 50 also begins compressing and reverses spring 51, can produce the strength that move backward built in preceding action disk 52 on the top and reverse spring 51, three connecting rods 55 will slide in the through hole 34 of disk 31, and make the some ventilative through hole 35 that wears on the disk 31 no longer by 53 sealings of back action disk, and the high pressure of disk 31 rear sides will be flowed to the front side of low pressure fast by ventilative through hole 35, make the pressure balance of disk 31 2 sides, after the high pressure conditions of disk 31 rear sides disappears, disk 31 once again roof pressure on the inlet hole 25 of the body of a gun 20, the through hole 531 of action disk 53 seals up inlet hole 25 and the pre-power springs 54 in the hollow slot 36 of disk 31 also will promote afterwards, make pressurized gas source that trigger 23 opened at inlet hole 25 rears pressure accumulation once again, and can at pressure accumulation to certain pressure, promote piston 30 fast once again and butter be released with continuous firing mechanism 50 cyclicity ground.

So, after the user can once detain and draw trigger 23, utilize piston 30 and continuous firing mechanism 50 continuously to release butter.As seen, if the user only needs button draw trigger 23 once need pour into butter in a large number the time, operates very easy.
