Abstract

FIELD: fastening systems preventing unauthorized usage. SUBSTANCE: device includes threaded member with head, nut, cap preventing possibility of end-side access to fastening assembly. Cap is mounted on head of threaded member and it is fixed in axial direction. Similar cap is mounted at side of nut. Casing in the form of high-strength bracket with openings is mounted on both caps for preventing lateral access. On inner surface of casing there are annular turnings formed by above mentioned openings. Caps have outer slit annular protrusions engaging with turnings of casing. Individual number is applied onto bottom portion of one cap at its outer side. Additional protection of threaded member with nut is provided by means of casing in the form of high-strength bracket.

Description

 The invention relates to fastening devices that prevent unauthorized use, and can be used in containers for storing products as a device that prevents unauthorized access to containers having an individual indication number, which is a non-separable conventional tool - a connection.

 A device is known for sealing a bolt used to fasten the cover of electric, gas and other installations, horizontal through holes formed in the bolt head extending in the radial direction. The device consists of a cylindrical cap covering the head of the bolt and a flat V-shaped spring, which serves to fix the cap. The cap consists of an external sleeve, closed on the upper side, freely rotating inside the external sleeve. The outer sleeve is provided with crackers for fixing the inner sleeve. In addition, a cavity under the bolt head is formed from bottom to top to it. The cavity reaches the inner sleeve. There are ratchet teeth on the inner side of the outer sleeve and the outer side of the inner sleeve to allow sleeves to rotate in one direction. The spring is equipped with hooks bent inward, which enter the said holes of the bolt head, and can freely rotate inside the inner sleeve [1].

 The disadvantage of this device is the design complexity and relatively easy access to opening the seal and its replacement.

 As a prototype, we take a device that prevents unauthorized use, containing a hex bolt, a cylindrical spacer element, a cap and an annular spring clip. A cap made of hardened material forms an inner groove; its inner diameter is slightly larger than the outer diameter of the distance element. The latter is made with an outer groove in which there is an annular spring clip. After fixing the two parts in the required relative position with a bolt, between the head of which and one of the parts there is a distance element, put on a cap, which when inserted, is moved until the annular spring clip pops into the groove, which ensures the cap is fixed. Instead of a bolt, a threaded rod with a nut can be used. A flange may be provided on the cap to prevent access to the mounting device. The remote element can be made in one piece with the bolt head, instead of the bolt, a bolt with a nut can be used, in this case the remote element is located between one of the fastened parts and the nut, and the bolt head is welded to another part [2].

 The disadvantage of this device is the ability to forcefully remove the cap with an available tool, such as pliers, pliers, flat-blade screwdrivers, etc., and then disassemble the parts to be connected.

 The technical problem to which the proposal is directed is to create a device that prevents unauthorized entry into containers used to store products, and having an indication number.

 The technical result, the solution of which the claimed device is directed, consists in securing the casing and caps with a threaded element, a nut, additional protection of the threaded element with a nut using a casing in the form of a high-strength bracket and using an individual tool to unscrew the nut from the threaded element.

 To solve the problem in a known device that prevents unauthorized use, containing a threaded element with a head in a nut, a cap that prevents the end-face access to the fastening device, the cap is mounted on the head of the threaded element and fixed in the axial direction, the same cap is installed on the nut side, on both caps are equipped with a protective cover against lateral access, which is a high-strength bracket with holes, the inner surfaces of the casing formed by their surfaces have annular grooves, caps made from the split external annular projections belonging to the housing bore, on that part of the outer side caps applied individually numbered.

 The device has a locking element between the nut and the mounting device.

 The device includes a head of a threaded element and a nut made under an individual key.

 Installing a cap over the nut, similar to that installed above the head of the threaded element, fixing the caps in the grooves of the protective casing and the protective casing in the form of a high-strength bracket additionally complicate access to the threaded element, nut and their disassembly. Drawing an individual number on this part of one of the caps from the outside allows you to determine the safety of the product in the container.

 The placement between the nut and the mounting device of the locking element improves the performance of the device.

 The execution of the head of the threaded element and nut for an individual key, for example, with grooves, protrusions, holes, further complicates the disassembly of the bolted connection.

 The drawing shows a diagram of the inventive device. The device that prevents unauthorized use, contains a threaded element 1 with a nut 2, caps 3, which prevent end access to the mounting device, a cover 4, which is a high-strength bracket with holes, is installed on both caps, the inner surfaces of the casing formed by these holes, have annular grooves, caps 3 are made with external split annular protrusions included in the grooves of the casing 4, on this part of one of the caps from the outside on the turn NOSTA A unique number is applied between the nut 2 and the fastening device is mounted a retaining element 5, the head of the screw member 1 and the nut 2 are made to individual key.

 The device operates as follows.

 The threaded element 1 and nut 2, wrapped with individual wrenches, tighten the connected elements and the casing 4. After tightening the threaded element 1 with the nut 2, caps 3 are installed in the holes of the casing 4, which are fixed by the external split ring protrusions in the annular groove of the casing 4. During control inspections of the container checks the safety of the device and the compliance of the individual number on the cap 3. Removing the caps 3 and disassembling the threaded element 1 with nut 2 is carried out by individual puller and keys.

 Thus, the proposed device solves the problem of preventing unauthorized entry into containers with products and their indication using an individual number.
