Detailed description of the invention
Below by drawings and Examples, this utility model is further elaborated.
As shown in Figure 1 to Figure 3: a kind of 50 lines determine chi, including main scale 1 and attached chi 2, attached chi 2 can be inlaid in main scale 1 the most actively.The front of main scale 1 indicates master calibration 3, and the front of attached chi 2 indicates attached scale 4.Master calibration 3 is consistent with attached scale 4, and precision reaches mm, and 0 graduation mark on attached scale 4 and 0 graduation mark on master calibration 3 overlap when attached chi 2 is inlaid in main scale 1 completely.It is provided with the fastening member 5 for being positioned on a certain position of main scale 1 by attached chi 2 on a wherein sidewall of main scale 1, another sidewall relative with fastening member 5 on main scale 1 is provided with the fine setting component 7 for being finely adjusted attached chi 2.
Attached chi 2 is the structure of convex shape for cross section, and the chute 6 that the front center of main scale 1 offers shape, size matches with attached chi 2, attached chi 2 is inlaid in chute 6 movably.It is so designed that, it is not necessary to other auxiliary member is movable in attached chi 2 i.e. can be limited in main scale 1, and owing to the front of attached chi 2 is exposed outside main scale 1, so having only to directly stir with hands attached chi 2, simple in construction when adjusting attached chi 2 position, it is easy to operation.
Fastening member 5 includes screw rod 1 and nut 1, offer, on the corresponding sidewall of main scale 1, the screwed hole 1 connecting with chute 6 and matching with screw rod 1, screw rod 1 threaded engagement is in screwed hole 1, nut 1 threaded engagement is positioned at the inner side movable sleeve of nut 1 on the outer end of screw rod 1, screw rod 1 and is provided with pad 1.Fine setting component 7 includes screw rod 2 71 and nut 2 72, offer, on the corresponding sidewall of main scale 1, the screwed hole 2 73 connecting with chute 6 and matching with screw rod 2 71, screw rod 2 71 threaded engagement is in screwed hole 2 73, nut 2 72 threaded engagement is in the outer end of screw rod 2 71, the inner side movable sleeve being positioned at nut 2 72 on screw rod 2 71 is provided with pad 2 74, the inner of screw rod 2 71 is provided with fine setting gear 75, position corresponding with fine setting gear 75 on attached chi 2 alongst offers and finely tunes the bar-shaped trough 76 that gear 75 matches, bar-shaped trough 76 is provided with tooth bar 77 on a wherein medial wall, fine setting gear 75 engages with tooth bar 77.In order to coordinate fine setting component 7 to be finely adjusted, fastening member 5 is also made corresponding adjustment.Particularly as follows: be provided with guide plate 79 in the inner of screw rod 2 71, alongst slide the fixed plate 78 being provided with for blocking attached chi 2 in the inner side of guide plate 79.When being embodied as, the inner side of guide plate 79 is provided with guide groove 710, is provided with some steel balls 711 in guide groove 710, and fixed plate 78 is slidably fitted in guide groove 710 by steel ball 711.And the length of guide plate 79 is more than the length of fixed plate 78.After attached chi 2 is adjusted to correct position, rotate forward the outer end of screw rod 1 so that whole fastening member 5 translates forward, fixed plate 78 compress the sidewall of attached chi 2, fix attached chi 2 with this.Then rotate forward nut 1 so that pad 1 is pressed on main scale 1, fix whole fastening member 5 with this.During fine setting, rotary screw 2 71, screw rod 2 71 drive fine setting gear 75 to rotate, be intermeshing owing to finely tuning gear 75 with the tooth bar 77 being arranged on attached chi 2, so fine setting gear 75 rotates and attached chi 2 can be driven to move up and down.Although the fixed plate 78 in fastening member 5 has blocked attached chi 2, but fixed plate 78 can be slided relative to guide plate 79, so attached chi 2 can move under the drive of fine setting gear 75 flexibly, plays the purpose of fine setting with this.After fine setting completes, then rotate forward nut 2 72 so that pad 2 74 is pressed on main scale 1, fix whole fine setting component 7 with this.
Master calibration 3 is marked in main scale 1 front and is positioned at the both sides of attached chi 2, and attached scale 4 is marked on attached chi 2 front center line.Being so designed that, the scale on attached chi 2 can be corresponding with the scale of both sides on main scale 1, it is simple to the attached chi of accurate observation 2 is relative to the position of main scale 1.
In order to more conform to practical operation needs, the total length of main scale 1 is designed between 1.5～2.0m, the total length of attached chi 2 is designed between 1.0～1.5m.Additionally, guide plate 79 longer than fixed plate 78 3～4cm, say, that by fine setting component 7, attached chi 2 can be finely tuned 3～4cm.
This utility model 50 line determines that the using method of chi (hereinafter referred to as this chi) is as follows:
During use, needing to coordinate level gauge (or theodolite) and tripod to be used together, this is also routine required equipment used when determining construction 50 line.First, first lay tripod, level gauge is placed on spider, leveling level gauge, at the optional level datum points of building yard, this chi is placed in this reference point location, calibration main scale 1 and attached chi 2, two ruler scales (referring to master calibration 3 and attached scale 4) are made to be completely superposed and ensure that ruler is vertical, then attached chi 2 is upwards pulled out, adjustment scale, make 0 graduation mark on attached chi 2 and the 50cm graduation mark on main scale 1 overlap, and screw fastening member 5 and fix attached chi 2 position, and can not there is loosening phenomenon.Read the number of degrees of attached chi 2 by level gauge, this number of division is exactly the level gauge level height height to line, thus can complete a step.Then this chi is taken to be constructed any one local, the level sight line of horizontal rotation level gauge, then fastening member 5 is unscrewed, adjusting attached chi 2 position makes level gauge read roughly attached chi 2 number of degrees originally read, then fastening member 5 is screwed, by fine setting component 7, attached chi 2 is finely adjusted again, finally makes level gauge accurately read attached chi 2 number of degrees originally read.Now, the position of attached chi 2 bottom 0 graduation mark is 50 lines at this, on wall in this place, rules on the first-class object of pillar.
This utility model 50 line determines chi, by coordinating of main scale 1 and attached chi 2, can save middle loaded down with trivial details calculation procedure, thus be greatly improved the efficiency determining 50 lines, and overall structure is simple, easy to operate；Meanwhile, attached chi 2 can be finely adjusted by fine setting component 7, so be greatly improved the precision being determined 50 lines.
Upper described foundation embodiment is enlightenment, and by above-mentioned description, relevant staff can carry out various change and amendment completely in the range of without departing from this utility model thought.The technical scope of this utility model is not limited to the content described in description.
