Abstract
The utility model discloses a portable telescopic scriber, which is characterized in that the scriber is provided with a telescopic rod (1), and the top end of the rod (1) is connected with a detachable brush (2) for scribing. The length of the scriber can be adjusted according to the height of a roadway, so that median lines can be scribed conveniently and rapidly without a climbing mine car, a waste rock raking machine, a ladder and the like, potential safety hazards are eliminated, the quality of the scribed median lines is ensured, and the labor intensity of coal mine technicians scribing the median lines is also reduced.
Description
Technical field
The utility model relates to a kind of mine laneway construction and uses scoring tool.
Background technology
In order to instruct tunnel safety under the coal mine, accurately to tunnel, guarantee that the tunnel is pointed to precisely, safe construction, draw center line in time, exactly with the indication roadway direction, have crucial meaning.For a long time, the colliery technician does not have special-purpose scoring tool when in underworkings, signing in the top to center line, gathers materials on the spot mostly, binds alternative scoring tools such as hairbrush with tamper, waddy, hammer drill; Because the tunnel that has is too high; Hold high and just have to climb mine car, rake cash machine, ladder etc. when tamper, waddy also can't reach back; Slip probably and fall on the ground; Not only strengthen labour intensity but also brought certain potential safety hazard, crooked, the fluctuation of picture also often occurred, can't guarantee the quality of drawn center line.
The utility model content
The utility model provides a kind of portable telescopic scriber in order to overcome the defective of prior art, and its length can be whenever and wherever possible according to the head-room adjustment, to draw center line quickly and easily.
The utility model technical solution problem adopts following scheme:
Portable telescopic scriber, its design feature are that scriber has a telescopic body of rod, are removably connected with a setting-out on the top of the said body of rod and use hairbrush.
The utility model design feature also is: the said flexible body of rod is the loop bar structure, has the more piece slide bar, and interconnective each slide bar end is provided with and cooperates helicitic texture and the spacing node of tightening.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model can be adjusted scriber length according to head-room, so that draw center line quickly and easily, need not to climb mine car, rake cash machine, ladder etc., has eliminated potential safety hazard, has both guaranteed drawn middle line mass also to reduce the labour intensity that the technician draws center line.
2, the utility model is simple in structure, and is easy to carry.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model single-unit Slide bar structure sketch map.
Label among the figure: 1 body of rod, 2 hairbrush, 3 slide bar ends, 41 external screw threads, 42 internal threads, 5 spacing nodes, 6 screws.
The specific embodiment
The utility model technical scheme is further specified through embodiment below in conjunction with accompanying drawing.
Referring to Fig. 1, scriber has a telescopic body of rod 1, is removably connected with a setting-out with hairbrush 2 on the top of the body of rod through screw and screw 6.
The body of rod is telescopic loop bar structure in the practical implementation; It has the more piece slide bar, and interconnective each slide bar end 3 is provided with and cooperates helicitic texture 4 and the spacing node of tightening 5, on the single-unit litter; As shown in Figure 2; Helicitic texture can be set to, and is made as external screw thread 41 in the thinner end of slide bar, is made as internal thread 42 in the thicker end of slide bar; Spacing node 5 structures do; Be made as spacing node in the thinner end of slide bar, be made as in the thicker end of slide bar and the corresponding spacing node that concaves of raised points, during use to outer lug; Pull out each slide bar; Tighten interconnective each slide bar end then, undertaken by spacing node spacing, thereby the light pressure that the body of rod receives when receiving gravity or setting-out when avoiding the use of shrinks automatically.
Claims (2)
1. the portable telescopic scriber is characterized in that, scriber has a telescopic body of rod (1), is removably connected with a setting-out with hairbrush (2) on the top of the said body of rod (1).
2. portable telescopic scriber according to claim 1 is characterized in that, the said flexible body of rod (1) is the loop bar structure, has the more piece slide bar, and interconnective each slide bar end is provided with and cooperates helicitic texture and the spacing node of tightening.
