Description
Affiliated technical field
The utility model relates to a kind of survey instrument, relates in particular to a kind of new molded lines and weighs down.
Background technology
At present, employed line weighs down on the market, have to carry being connected that line and line weigh down be to be in free state, with after need line is wound up, if twine badly, use next time just more at random; Though what have has Wiinding cartridge and is that to weigh down with line be isolating construction, cumbersome during use, and cone tip hardness is lower, can not directly do projection mark with the awl point, but need behind the messenger wire to carry out with the marker pen that is equipped with, so not only bothered but mark inaccurate, and can influence measuring accuracy.
Summary of the invention
For the deficiency that exists in the use that overcomes existing line bob, provide a kind of new molded lines to weigh down.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of new molded lines weighs down to be made up of falling body, line:
A) weigh down the screw thread end face that covers and be fixed with the coiling wheels by the reel pack support, the other end of weighing down lid is provided with wire sleeve, carrying an end of line fixes and is wrapped on the coiling wheels, the other end of carrying line passes by the wire sleeve center pit and is carrying the fixing wired pearl of line end, weigh down lid and be fixed together by screw thread and falling body, the awl end of described falling body is provided with the awl point.
B) centre of described coiling wheels is provided with the plane spiral spring, and its side is provided with ratchet-wheel gear.
Described wire sleeve also can be set together with the bob lid.
The outer rim of described bob lid is provided with annular knurl.
Described awl tip has hardness.
The beneficial effects of the utility model are that extraction can free line being overlapped from winding the line during use is bored tip and can directly be done projection mark again, and is simple in structure, easy to use, measures accurately.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure diagram of the present utility model.
Fig. 2 is an outside drawing of the present utility model.
1. falling bodies among the figure 2. weigh down lid, and 3. wire sleeve is 4. carried line, 5. line pearl, 6. reel support, 7. coiling wheels, 8. awl point.
Embodiment
As shown in Figure 1 and Figure 2, a kind of new molded lines weighs down to be made up of falling body, line, it is characterized in that:
A) weigh down and cover 2 screw thread end face and be fixed with the wheels 7 that wind the line by reel pack support 6, weigh down and to cover 2 other end and be provided with wire sleeve 3, carrying an end of line 4 fixes and is wrapped on the coiling wheels 7, the other end of carrying line 4 passes by wire sleeve 3 center pits and is carrying the fixing wired pearl 5 of line 4 ends, weigh down and cover 2 and be fixed together by screw thread and falling body 1, the awl end of described falling body 1 is provided with bores sharp 8.
B) centre of described coiling wheels 7 is provided with the plane spiral spring, and its side is provided with ratchet-wheel gear.
Described wire sleeve 3 also can cover 2 with bob and be set together.
The outer rim of described bob lid 2 is provided with annular knurl.
Sharp 8 tips of described awl have hardness.
During use,, according to using needs to regulate, make by ratchet-wheel gear and to carry line 4 and keep certain extension elongation, during measuring point to be determined, can directly make a mark with awl sharp 8, for measurement data around the extension elongation of carrying line 4 with hand respectively backguy pearl 4 and falling body 1.
After finishing using, stretch and to carry line 5 and falling body 1, unclamp,, make and propose line 4 withdrawals and be wrapped on the coiling wheels 7 at once by the effect of plane spiral spring.
