Description

The device relates to fasteners and can be used to fix sheet materials to the frame from the inside.

A device for fixing sheet materials [1]. The device contains a hexagonal head, a threaded rod, a drill bit and a washer with a gasket. The device is used as follows. The fixed sheet material is mounted on the frame. Further, from the side of the sheet material, using a screwdriver with the corresponding nozzle, the fixed sheet material is drilled by the device with a drill tip, then the device is screwed into the frame by threading. The screwing continues until the washer snugly fits with the gasket to the fixed sheet material. The device provides tightness of the interface sealing "washer - sheet material".

The disadvantage of this device is the inability to fix the sheet material to the frame if there is access only from within the frame.

A device for fixing sheet material on a frame [2]. The device contains a screw with a plastic anchor fixed to it. The dowel consists of two parts: a part with a guide hole and a thrust pad and a part with internal thread. Parts are connected by jumpers. The assembly screw is threaded through the guide hole and screwed into the hole with an internal thread. The device works as follows. The fixed sheet material is mounted on a frame of thin-walled material. Next, a through coaxial hole is made in the sheet material and the frame. The device pushes into the hole all the way into the thrust pad. Further, the screw twists and draws the part with internal thread to the part with a guide hole and a thrust pad. In this case, the jumpers are deformed forming a rhombus. With further tightening of the screw, the two sides of the rhomb abut against the fixed sheet material and press it to the frame by means of a thrust pad on the dowel.

The disadvantage of this device is the inability to seal a through hole and the inability to fix sheet material on a thick-walled frame.

A known device adopted for the prototype [3]. The device comprises a cylindrical element with an external thread and a tube with a thrust pad on one side and an internal thread on the other. The tube has longitudinal slots and is made of metal. A cylindrical element with an external thread is threaded into the tube from the side of the thrust pad and twisted into the internal thread of the tube. The device works as follows. The fixed sheet material is mounted on a frame of thin-walled material. Next, a through coaxial hole is made in the sheet material and the frame. The device pushes into the hole all the way into the thrust pad. Further, the cylindrical element with an external thread twists and compresses the tube. At the same time, jumpers formed by longitudinal slots are deformed to form protrusions from two unequal parts. With further twisting of the cylindrical element with an external thread, smaller parts of the protrusions abut against the fixed sheet material and press it to the frame by means of a thrust pad on the tube.

The disadvantage of this device is the inability to seal the through hole.

The technical result of the claimed device consists in sealing the mounting hole.

The technical result is achieved in that a cylindrical element with an external thread is provided on one side with a stop element with an internal thread, and on the other hand, a sealing element and a sealing plug are fixed.

The list of devices:

FIG. 1 is a diagram of a device;

FIG. 2 is a diagram of a device in an opening of a carcass and a fixed sheet material;

FIG. 3 is a diagram of an installed device.

A device for fixing sheet materials contains a cylindrical element with an external thread 1, which can be of any length, a stop element with an internal thread 2, a sealing element 3 fixed at the end of a cylindrical element with an external thread 1, and a sealing plug 3 fixed at the end of the cylindrical element with an external thread 1 (see Fig. 1). The sealing element 3 and the sealing plug 4 are made of elastic material. As a cylindrical element with an external thread 1, for example, a hairpin can be used. As a supporting element with a female thread 2, a nut may be used.

A device for mounting sheet materials works as follows.

The fixed sheet material 5 is mounted on the frame 6 (see. Fig. 2). Through, coaxial holes are made in the frame and the fixed sheet material. The device is inserted into the hole (see. Fig. 2). In the process of inserting the device into the hole, the sealing element 3 and the sealing plug 4 are elastically deformed to the diameter of the hole. Further, the thrust member with the internal thread 2 is twisted and the cylindrical member with the external thread 1 is pulled from the hole to the position indicated in FIG. 3. At the same time, the sealing element 3 is deformed, sealing the hole, and the sealing plug 4 seals the interface with the fixed sheet material.

The use of the claimed device provides the following advantages:

- providing the possibility of fixing the sheet material in the absence of access from the fixed sheet material;

- providing the ability to fix sheet material on the frame of any thickness;

- sealing the holes in the fixed sheet material.
