CN2123802U - Thermo-contraction number marking tube for pipe line - Google Patents

Abstract

The utility model provides a thermo-contraction number marking tube with convenient use which can be fastened on the pipe lines which need to make number. The number marking tube can overcome the defects that existing number marking tubes slide along pipe lines, rotate, easily drop out, and take large space. Relative symbols (numbers and letters or letters) are print on the outer wall of the thermo-contraction number marking tube with a thin wall. When in use, the thermo-contraction number marking tube is sheathed on the position of pipe lines where numbers are needed to be displayed, and then the number marking tube is heated to achieve contraction and fixed on pipe lines. The number marking tube is especially suitable for pipe lines which are arranged in the devices with small space, high temperature, and vibration.

Description

Thermo-contraction number marking tube for pipe line

The utility model relates to a kind of thermal shrinkage number pipe, is particularly suitable for narrow, the high temperature in space, the demonstration of pipeline coding in the vibratory equipment.

Existing various pipeline number pipes are in order to install, the internal diameter of number pipe must be greater than the external diameter of required coding pipeline, unfixing, so causing the number pipe slides along pipeline, rotate or come off, thereby make recognition coding very inconvenient, and larger-diameter number pipe will occupy bigger space, and the pipeline that special occasions is used is installed by difficulty or the influence wiring is attractive in appearance.

The purpose of this utility model is to provide a kind of easy to use, can be fastened on the number pipe that needs on the coding pipeline.

The utility model is achieved in that at thin-walled heat-shrink tube outer wall and stamps relevant symbol (number, letter or literal), tailors into the number pipe of certain-length and shape (as rectangle, trapezoidal, rhombus etc.).During use pyrocondensation number pipe box is required to show the position of sign indicating number at pipeline, heating shrinks the number pipe to be fastened on the pipeline then.

Use the utility model does not almost increase the cost of original product, but can overcome present used number pipe and take up space greatly, along the pipeline slip, rotates, easily comes off or make deficiencies such as recognition coding difficulty, and it is narrow especially to be in the space in the pipeline installation.High temperature, in the time of in the equipment of vibration, the utility model compare with the existing numbers pipe have high temperature resistant, ageing-resistant, firm, show the sign indicating number clear, be convenient to advantages such as pipeline installation and maintenance.

Below in conjunction with accompanying drawing the utility model and use are further described.

Fig. 1 is a front elevation of the present utility model;

Fig. 2 is a side view of the present utility model;

Fig. 3, Fig. 4 are application of the present utility model.

With reference to Fig. 1, Fig. 2, (Fig. 1 is a rectangle to have certain-length and shape, also can needs be tailored in echelon according to using, rhombus etc. helps the shape of fast contraction) heat-shrinkable tube (1), on the heat-shrink tube outer wall, stamp relevant number, letter or literal (2) constitute pyrocondensation number pipe.

With reference to Fig. 5, when Fig. 4 uses pyrocondensation number pipe (3) being enclosed within needs coding pipeline (4) will show the position of sign indicating number, with lighter or hair drier heating number pipe (3) is tightened on the outer wall of pipeline (4).

Claims (1)

1, a kind of pipeline pyrocondensation number pipe is characterized in that it becomes to be suitable for fast contraction shape (rectangle, trapezoidal, rhombus) by tailoring, and is printed on relevant number, letter or literal (2) on outer wall, and the thin-walled heat-shrink tube constitutes.
