Abstract

The utility model relates to a nail gun head safety locking mechanism, in particular to a gun head safety push rod which is characterized in that the inner end of the gun head security push rod is connected with one end of a safety pad; the other end of the safety pad is matched with the corresponding part of a trigger; a locking piece is further arranged on the housing of the nail gun; and the locking piece is buckled with the safety pad in a movable position-retaining manner to constitute a safety pad position-retaining fixing device. When the utility model is in use, after the gun head safety push rod is compressed and the locking piece is buckled and fixed with the safety pad, the safety pad cannot be moved or restored to the original position, namely the safety pad is locked or in a safety-free state, nails can be jetted by frequently pulling the trigger; and after the locking piece is released, the gun is in a safety-available state, the safety-available state needs to be switched to the safety-free state before jetting nails each time. The utility model has the advantages of simple mechanism, convenient switch, suitability for various use states of the nail gun, safety, and reliability.

Description

Nail rifle rifle head insurance retaining mechanism

Technical field: the utility model relates to a kind of nail rifle, particularly follows closely the insurance institution of rifle rifle head.

Background technology: the nail rifle that industries such as present finishing, carpenter are used generally all is provided with insurance institution, prevents that trigger from arbitrarily being pulled and nailing.Insurance institution commonly used utilizes rifle head insurance push rod mobile insurance pad, safety pad then matches with trigger, whenever opening insurance uses a capital to reset, so each nailing all must be pushed down the triggering pulling again of insurance push rod, operation is very inconvenient when needing frequent nailing, if insurance institution is removed, is easy to generate safety problem again.

Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of changeablely to be had, the nail rifle rifle head insurance retaining mechanism of no safety position.

The utility model comprises rifle head insurance push rod, the inner end of this rifle head insurance push rod and an end of safety pad are connected, and the safety pad other end then cooperates with the trigger corresponding site, also is provided with locking member on the housing of nail rifle, the movable gear engaging of this locking member and safety pad constitutes safety pad gear fixture.

The utility model is compressing rifle head insurance push rod and locking member is fixed behind the safety pad, and safety pad can not move and reset, i.e. insurance locking is in no safety position, and trigger can frequently be pulled nailing.After locking member is released, then reverted to safety position, need open at every turn and insure nailing again.Mechanism of the present utility model is simple, and easy switching adapts to the various user modes of following closely rifle, and is safe and reliable.

Further specify the utility model below in conjunction with drawings and Examples.

Description of drawings: Fig. 1 is the main structure schematic diagram of embodiment;

Fig. 2 is the A-A cross-sectional schematic of Fig. 1;

Fig. 3 is the front view of safety pad;

Fig. 4 is the front view of sliding axle;

Fig. 5 is the no safety position schematic diagram of Fig. 1;

Fig. 6 is the B-B cross-sectional schematic of Fig. 5.

The specific embodiment: as shown in Figures 1 to 4, the inner end of rifle head insurance push rod 1 and an end of safety pad 2 are connected, and safety pad 2 other ends then cooperate with trigger 3 corresponding sites.Also be provided with locking member 5 on the housing 4 of nail rifle, this locking member 5 and safety pad 2 movable gear engagings constitute safety pad gear fixture.Locking member 5 can adopt multiple configuration state, as fastener, removable pin etc., the locking member 5 of present embodiment adopts sliding axle, safety pad 2 is provided with the groove 6 that the two ends width differs, the end of sliding axle is then crossed and is placed groove 6, and sliding axle is the multidiameter form, its diameter that does not exist together respectively with the two ends width corresponding matching of groove 6, constitute horizontal shaft type safety pad gear fixture.

As shown in Figure 5 and Figure 6, after compressing rifle head insurance push rod 1 and safety pad 2 also moved to right, press locking member 5 and make the groove 6 narrower places of thick diameter parts retaining at safety pad 2, safety pad 2 is fixed and can not moves, be equivalent to compress rifle head insurance push rod 1 always, safety position is disengaged, can frequent easily cocking 3.Press locking member 5 again and make thin diameter parts be positioned at groove 6 places of safety pad 2, can not block groove 6, safety pad 2 can be reset together with rifle head insurance push rod 1, returns to the safety position that has as depicted in figs. 1 and 2, switches easily.

In the reality, the locking member 5 of slip shaft type also can be made d-axis, puts stair-stepping button 9 at axle head, can carry out gear equally with the different in width place of groove 6 and cooperate.

Present embodiment is provided with two circle grooves 7 on sliding axle, also be provided with locating piece 8 and groove 7 elasticity location on the housing 4 and cooperate, and can prevent that like this sliding axle from moving, and locking state is stable.
