POWDER MOUNTING GUN

The utility model relates to hand-held portable tools with a power drive and can be used in construction and installation work.

Known manual device for driving pins by the action of powder gases (see USSR patent No. 326768 for CL B25 1/10, publ. 19.11.72, bull. No. 4), consisting of a housing with a handle, movable relative to the barrel body, shutter mounted on the housing, spring-loaded spring return sleeve interacting with the barrel, on which is fixed a sear interacting with the striker and the trigger lever.

The known device performs the functions of a mounting gun and allows you to hammer dowels into the machined surface;; by attaching structures to a concrete and other solid base.

A disadvantage of the known device is the increased complexity of manufacturing the device, caused by the presence of a movable sleeve with high requirements for the accuracy of its manufacture, which reduces the manufacturability of the device in large-scale production.

The objective of the utility model is to increase manufacturability by simplifying the design.

The technical result is a reduction in the requirements for manufacturing parts.

To achieve this result in a known device, including a housing with a handle, a barrel movable relative to the housing, a shutter, a pinch interacting with the striker and the trigger lever, at least one return spring, the shutter is movable and spring loaded with at least one return spring, and the sear is installed on the shutter.

- the sear installed on the shutter is movable relative to the shutter in the longitudinal direction;

-the interaction of the whisper with the striker and the trigger lever is carried out by removing the sear from the mesh with the movable shutter due to the action of the trigger lever and the cocked striker is released;

-Sheptalo spring-loaded relative to the striker.

The utility model is illustrated by means of the drawings, in which FIG. 1 shows the arrangement of a powder-mounted gun, in FIG. 2 - elements of the firing mechanism of the powder mounting gun. ,

The powder mounting gun includes a housing 1 with a handle 2, a barrel 3 movable relative to the housing 1, a movable bolt 4, a sear 5, interacting with elements of the trigger mechanism - the striker 6 and the lever 7, the trigger 8, at least one return spring 9 , spring 10 whispered 5.

The powder mounting gun works as follows.

Before the shot, 3 dowels are installed in the barrel, then the trigger mechanism is platooned by resting the barrel on the surface to be treated. In this case, the barrel 3 moves back, acting on the shutter 4, pushes it, compressing the return spring 9 until the whisper 5 is established in its original position, i.e. opposite the trigger lever. When the trigger 8 is pressed, the trigger lever 7 exerted on the sear 5, moving it and, as a result, releasing the hammer 6, which, under the action of the mainspring 9, is thrown forward, igniting the powder charge.

As a result, the piston is pushed forward, driving the dowel into the workpiece.

After removing the stop, the barrel 3 and the shutter 4 are moved forward under the action of the return spring 9. At the same time, the shutter 4 occupies a position in which the gimbal 5 is released from the obstructing action of the striker and lowers

arrow and shot are carried out in accordance with the sequence described above.

Spring 10 provides reliable engagement of the striker and bolt.

The utility model makes it possible to increase the manufacturability of manufacturing a powder mounting gun by reducing the requirements for precision manufacturing of gun parts — the shutter and the body, and simplifying the design.
