To this end, we propose a portable hand-held construction for a grease gun and method of use thereof to address the above problems.

Disclosure of Invention

The present invention is directed to a portable handheld structure of a grease gun and a method for using the same to solve the problems set forth above in the background art.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a portable handheld structure of grease gun, includes the grease gun body, be equipped with the handheld subassembly of extension on the grease gun body, just the handheld subassembly of extension includes handle and depression bar, the one end of handle is equipped with fixing base and locking seat, the fixing base with handle fixed connection, just be equipped with the jack on the fixing base, be equipped with on the locking seat with the draw-in groove that the grease gun body agrees with mutually, just the lower extreme of locking seat be equipped with two with the corresponding clutch yoke of jack, the outside of clutch yoke is equipped with the toper arch, the upper end of locking seat is equipped with thread tightening section of thick bamboo and spacing claw, the one end of thread tightening section of thick bamboo with locking seat fixed connection, spacing claw with thread tightening section of thick bamboo swing joint, just the both ends of spacing claw all with the protruding counterbalance of toper.

This setting, through establish the handheld subassembly of extension on the grease gun body, the handheld subassembly of extension comprises two parts, it is all through locking seat and grease gun body fixed connection, be equipped with the jack that is used for being connected with the locking seat on the fixing base, during the installation, only need lock the seat card earlier on one's body, then peg graft on the fixing base with its one end that has the engaging lug, install the bracing piece in the thread tightening section of thick bamboo after that, at the in-process of installation, the bracing piece can promote spacing claw downwards, spacing claw can be inconsistent with the protruding counterbalance of toper on the engaging lug, thereby promote the engaging lug and make its firm clamp on one's body the rifle. The existence of the lengthened handheld assembly enables the length of the grease gun body to be lengthened, so that equipment at a high position or a crack can be lubricated more conveniently, and the grease gun is more convenient to use.

Preferably, the grease gun body comprises a gun body, a gun head and a pull rod, a piston is arranged in the gun body, the pull rod is positioned at one end of the gun body and fixedly connected with the piston, the gun head is positioned at the other end of the gun body and is in threaded connection with the gun body through threads, a handle is arranged on the gun head, when the grease gun is used, the gun head is firstly detached, one end of the gun body is placed into a grease barrel, then the pull rod is pulled, the pull rod drives the piston to move, grease is pumped into the gun body, the gun head is installed, then the pull rod is pushed to exhaust the grease, and finally the grease in the grease gun body can be pumped out by pressing the handle; the tail part of the handle is provided with a limiting groove, when the lengthened handheld assembly is installed on the grease gun body, the handle is driven to move through the pressure rod, so that grease in the grease gun body is ejected, and due to the limiting groove, the handle and the pressure rod are not easy to slip and are easy to operate; the pull rod is T font, just be equipped with on the pull rod with the spacing recess of U-shaped that the handle agrees with mutually, through the spacing recess of U-shaped, the pull rod can the joint on the handle, and the handle has two contact points through fixing base and locking seat and body of a gun like this, has a contact point through spacing recess of U-shaped and pull rod, and stability is higher.

Preferably, be equipped with the bracing piece on the depression bar, just the one end of bracing piece with thread tightening section of thick bamboo spiro union, the bracing piece through the round pin axle with the depression bar pin joint, the one end of depression bar is equipped with the elbow, and the bracing piece plays the effect of a connection between depression bar and latch closure, and the depression bar rotates with the bracing piece to be connected, and the bracing piece then with latch closure fixed connection, is equipped with the elbow in the one end of depression bar, and the elbow is inconsistent with the handle, when needs operating handle, only need outwards break the depression bar off with the fingers and thumb, can press the handle to body of a gun direction through the depression bar, the depression bar is equivalent to a lever, and when in-service use, can be more laborsaving control the grease gun through the depression bar and beat butter.

Preferably, still be equipped with locking mechanism in advance on the handle, just locking mechanism includes the kicking block in advance, the kicking block pass through spacing spring with handle elastic connection, just the one end symmetry of kicking block is equipped with the toper latch.

This setting, during the installation, stir the kicking block earlier, treat that the locking seat pegs graft back together with the fixing base, loosen the kicking block, the kicking block can be under spacing spring's effect to the fixing base direction motion, under the promotion of kicking block, the toper latch can be pegged graft between connection claw and fixing base, because the toper latch is the toper form, along with the motion of toper latch, it can be gradually outwards promotes the connection claw motion, that is to say, when fixed, can provide an exogenic power for connecting the claw through the toper latch, thereby with the locking seat chucking, make the installation that follows become more convenient.

Preferably, the thread fixing cylinder is provided with a fixing groove for fixing the limiting claw.

This setting, spacing claw can be movable in the fixed slot, when the bracing piece is fixed with the thread tightening section of thick bamboo, the bracing piece can promote the spacing claw motion in the fixed slot, spacing claw and connection claw all peg graft in the jack, under the promotion of bracing piece, spacing claw can the downstream, thereby it is inconsistent with the toper arch of being connected on the claw, because the toper has the inclined plane on the arch, under the promotion of spacing claw, it can be crooked to grease gun body direction to connect the claw, just can clip the grease gun body through two connection claws like this, thereby make the locking seat fix together with the grease gun body.

Preferably, the fixing seat is sleeved on the handle, and the fixing seat is detachably connected with the handle through a screw.

In the arrangement, the fixed seat is detachably connected with the handle through the screw, the position of the fixed seat can be adjusted, and the use is more convenient.

A method of using a portable hand-held structure for a grease gun, comprising the steps of:

firstly, disassembling a gun head, then placing one end of a gun body into a butter barrel, pulling a pull rod, and driving a piston to move by the pull rod so as to pump butter into the gun body;

step two, then installing the gun head, then pushing a pull rod, wherein the pull rod drives a piston to move in the gun body, and the exhaust operation can be carried out on the inner cavity of the gun body until redundant gas is exhausted;

and step three, finally, pressing the handle towards the gun body through the pressure rod, meanwhile, arranging a spring in the gun head, returning the handle to the original position under the action of the spring, driving the gun body and the piston to move relatively by the handle, further discharging the grease from the gun head, and reciprocating the grease to eject the grease in the gun body.

Compared with the prior art, the invention has the beneficial effects that:

1. according to the grease gun, the lengthened handheld assembly is arranged on the grease gun body, and the length of the grease gun body is lengthened due to the lengthened handheld assembly, so that equipment at a high position or a crack can be lubricated more conveniently, and the grease gun is more convenient to use.
