(54) ПИШУЩИЙ ИНСТРУМЕНТ(54) WRITING TOOL

II

Изобретение относитс к пишущим инструментам .The invention relates to writing instruments.

Известен пишущий инструмент, содержащий расположенный в корпусе пишущий стержень и установленную над стержнем винтовую пару дл ограничени осевого перемещени стержн 1.A writing instrument is known that contains a writing rod located in the housing and a screw pair mounted above the rod to limit the axial movement of the rod 1.

Однако известный пищущий инструмент при простоте конструкции требует наличи нескольких сменных элементов различной длины, чтобы использовать стержни различной длины.However, the well-known squeaking tool with the simplicity of design requires the presence of several interchangeable elements of different lengths in order to use rods of different lengths.

Цель изобретени - расширение диапазона размеров используемых стержней.The purpose of the invention is to expand the range of sizes of rods used.

Указанна , цель достигаетс тем, что винт имеет сквозное осевое отверстие дл размещени конца стержн , а гайка выполнена в виде стакана.This goal is achieved by the fact that the screw has a through axial bore for accommodating the end of the rod, and the nut is made in the form of a glass.

На фиг. 1 показан пищущий инструмент, продольный разрез, при использовании стержн наибольшей длины; на фиг. 2 - то же, при использовании стержн наименьшей длины; на фиг. 3 - разрез А-А на фиг. 1; на фиг. 4 - разрез Б-Б на фиг. 2; на фиг. 5 - разрез В-В на фиг. 2.FIG. 1 shows a squeaking tool, a longitudinal section, when using a rod of the greatest length; in fig. 2 - the same, when using a rod of the smallest length; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. 2; in fig. 5 shows a section B-B in FIG. 2

Пишущий инструмент содержит установленный в корпусе I пишущий стержень 2 и наконечник 3.The writing instrument comprises a recording rod 2 installed in the housing I and a tip 3.

Над стержнем 2 дл ограничени его осевого перемешени установлена винтова пара в виде винта 4 и гайки 5. Винт 4A screw pair in the form of screw 4 and nut 5 is installed above rod 2 to limit its axial mixing. Screw 4

5 имеет сквозное осевое отверстие дл размещени конца стержн 2, а гайка 5 выполнена в виде стакана. Диаметр осевого отверсти больше диаметра стержн 2. При использовании пишущего стержн 25 has a through axial bore to accommodate the end of the rod 2, and the nut 5 is made in the form of a glass. The diameter of the axial bore is larger than the diameter of the rod 2. When using a writing rod 2

Q наибольшей длины (фиг. 1) винтова пара устанавливаетс так, чтобы стержень свободным концом выходил во внутреннюю полость винта. Дл ввода длинного стержн 2 в рабочее положение необходимо соединить винт 4 и гайку 5 между собойThe longest Q (fig. 1) of the screw pair is set so that the rod with the free end extends into the internal cavity of the screw. To enter the long rod 2 into position it is necessary to connect the screw 4 and the nut 5 to each other.

15 по резьбе и вставить их в корпус 1 так, чтобы гайка 5 глухим концом упиралась в основание пищущего инструмента. Затем необходимо вставить стержень 2 до упора в гайку 5 и навернуть по резьбе наконечник 3.15 along the thread and insert them into the housing 1 so that the nut 5 with the blind end rests against the base of the squeaking tool. Then you need to insert the rod 2 until it stops in the nut 5 and screw the tip 3 along the thread.

Claims

In order to change the rod 2, it is necessary to disassemble the writing instrument in reverse order. To install the shortest writing rod 6, it is necessary to connect the screw 4 and the nut 5 to each other so that the length of the screw pair becomes the greatest. Then it is necessary to install the screw pair in the housing 1 so that with its deaf base it faces the tip 3, then insert the writing rod up to the stop at the base of the nut 5 from the outside and turn the tip 3 along the thread. FIG. Figures 3, 4, and 5 show the mutual arrangement of the elements of a writing instrument in various sections using rods of the largest and smallest lengths. In this case, the full length of the screw pair is equal to the difference in the lengths of the rods used - the longest and the shortest. To use rods of any intermediate length, it is necessary to change the length of the screw pair by changing the relative position of the screw and nut. The proposed writing instrument is more versatile and creates ease of use due to the possibility of using commercially available rods of various lengths, which increases its working capacity and lengthens its service life. Claims of the invention: A writing instrument comprising a food rod located in the housing and a screw pair mounted above the rod to restrict the axial movement of the rod, characterized in that, in order to expand the size range of the rods used, the screw has a through axial hole to accommodate the end of the rod, and the nut is made form of glass.
