Abstract

A pusher comprises a main body and a joint matched with the main body, wherein the main body comprises a handle, a push mechanism, a straight rod and a positioning mechanism, wherein the straight rod transversely penetrates through and arranged on the main body; the push mechanism is movably connected with the straight rod and can be used for pushing the straight rod to move forwards under control; the positioning mechanism is movably connected with the straight rod and can be used for locking or unlocking the straight rod; a notch matched with the joint is formed in the front end of the main body. According to the pusher, a push plate is driven to move in the length direction of the straight rod by pressing a push handle on the main body, and the straight rod is driven to move forwards under the action of friction force of (the friction force is larger than pressure exerted by the positioning mechanism). The pusher can be used for pushing a pull rod when a compressor is repaired, is easy to operate and convenient, and saves time and labor.

The specific embodiment

Below the utility model will be further described by the specific embodiment.

With reference to Fig. 1, Fig. 2, a kind of pusher, comprise main body 1 and adaptive joint 2 with it, main body 1 comprises one handle 11, a pushing mechanism, a straight-bar 12 and a location mechanism. main body 1 left and right, middle part has been formed through a thrust zone 13, and main body 1 front end also offers the breach suitable with joint 14.Handle 11 is positioned at this thrust zone 13 belows, and straight-bar 12 is horizontally through this thrust zone 13.Straight-bar 12 cross sections are that hexagon and its front end are provided with round end section 15, and rear end is provided with hand and grabs section 16.On main body 1, be positioned at thrust zone 13 both sides and also be respectively equipped with the reinforcement 17 distributed along straight-bar 12 length directions, be used to strengthening the intensity of main body 1.

Pushing mechanism comprises a pushing handle 21, a push pedal 22 and one first elastic component 23.Push pedal 22, pushing handle 21 tops and the first elastic component 23 are positioned at this thrust zone 13, and this pushing handle 21 is rotationally connected with main body 1 by a rotating shaft 24, and rotating shaft 23 is positioned at these thrust zone 13 belows and handle 11 positions, boundary.This push pedal 22 is sheathed on straight-bar 12 and with pushing handle 21 tops and is flexibly connected, and this first elastic component 23 also is sheathed on straight-bar 12 and opens and peaks between push pedal 22 and main body 1.With reference to Fig. 3, Fig. 4, when controlling relative handle 11 action of pushing handle 21, push pedal 22 is driven moves along straight-bar 12 length directions, and under the effect of frictional force (this frictional force is greater than the detent mechanism applied pressure), driving straight-bar 12 moves forward, when stop operation, push pedal 22 is return under the effect of the first elastic component 23, and the position of straight-bar 12 remains unchanged under the effect of detent mechanism.

Detent mechanism is for the position of locking or release straight-bar 12, comprise a pressing plate 31, one second elastic component 32 and a fixed leg 33, fixed leg 33 is fixed in main body 1 rear end, pressing plate 31 is arranged on straight-bar 12 and an end and 33 flexible connections of this fixed leg, the second 32 of elastic components peak between pressing plate 31 and main body 1 and order about pressing plate 31 inclinations, by the 31 pairs of straight-bars of pressing plate 12 that tilt, produce pressure and lock straight-bar 12 positions, with reference to Fig. 5, when pressing these pressing plate 31 other ends and make pressing plate 31 vertical with straight-bar 12, the pressure of 31 pairs of straight-bars 12 of pressing plate disappears, thereby release straight-bar 12, the hand that now can hold straight-bar 12 is grabbed section 16 straight-bar is pulled out.

Joint 2 one ends are provided with two sections screwed pipes 3 that radius is different, and the other end is provided with the connecting portion 4 suitable with main body breach 14, main body breach 14 are set for trapezoidal, and these corresponding connecting portion 4 cross sections are also trapezoidal, and connecting portion 4 bottoms also are provided with limiting section 41.

When the utility model can be used for the auxiliary repair compressor, connect to promote the pull bar in compressor, observe the valve block trend when filling suction valve chip and valve seat, or check whether pull bar is flexible, or whether normally put in place during dress cylinder pressure lid.This pull bar is connected with outside oil connection or chock plug, adopts aforesaid impeller operated step as follows:

1) oil connection or chock plug are pulled down, replaced joint oil connection or chock plug to be connected with pull bar;

2) the pusher front end is docked with joint and makes the pole front end buckle in joint;

3) with hand, pull and press pushing handle to make straight-bar move forward, repeat to pull and press for several times;

4) according to the needs of maintenance step, press pressing plate, now under the pull bar effect, straight-bar is rebounded;

5) repeating step 3) and 4) repeatedly advance or rebound with the utility model pusher, in order to allow the required step of maintenance personal's observe and decide, as observe cylinder jacket and whether with the pull bar of main frame, match, whether the little push rod of cylinder is flexible, also have suction valve chip whether to move up and down etc., the maintenance step that judgement specifically needs according to actual conditions.

During as overhaul, mainly that cylinder cap is taken apart, crankcase cover is taken apart, cylinder jacket and piston are taken apart, the related pull bar of oil pipe oil circuit and oil cylinder place position checks (oily piston, spring and pull bar, consisting of in oil cylinder), that is to say, maintenance, need to tear valve seat, valve block, cylinder, connecting rod, piston open each time.Some type need to be torn cylinder cap open and pull valve group.Indispensable effect when at this moment pull bar just plays assembling.

Adopt pusher of the present utility model to coordinate maintenance to compare and can save time about one hour with tradition, save time and laborsaving.

Above are only a specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
