Abstract
The utility model relates to a kind of slide level bar; comprise chi body, vernier, air level and circular hole; described chi body is provided with vernier, air level and circular hole; dovetail groove is provided with bottom described chi body; it is characterized in that: described slide level bar also comprises port protection cover; described port protection cover comprises port protection cover one and port protection cover two; it is separately positioned on chi body two ends; and it is chimeric with the dovetail groove on chi body; described port protection cover one and port protection cover two are respectively equipped with three fixture blocks, between fixture block, are provided with groove.The design of the utility model middle port protective sleeve, can avoid slide level bar two ends to damage, thus extends the service time of surveyor's staff, the hand of user can be avoided to be subject to scratch simultaneously.In addition, draw point and pencil are also arranged on slide level bar by the utility model, and this slide level bar is easy to use simply.
Description
Technical field
The utility model relates to a kind of surveyor's staff, is specifically related to a kind of slide level bar.
Background technology
In survey instrument, surveyor's staff is the instrument often used, it through being usually used in checking, measuring, line, equipment is installed or the construction of Industrial Engineering, is therefore requisite instrument in measuring equipment.Compared with traditional surveyor's staff, present surveyor's staff has greatly improved, and it is also provided with the air level of other angles except horizontal levelling bubble and vertical level bubble, surveyor's staff present in addition mostly with vernier, in use easily.But the two ends of present most slide level bar are with wedge angle, and in actual use, any design is not carried out to the two ends of slide level bar, make the two ends of slide level bar easily wear and tear in use.And slide level bar is generally magnalium material, in use especially easily scratches hand.Traditional surveyor's staff comprises chi body, chi body can need to be made up of various material according to difference, in use, usually surveyor's staff and body surface are fitted, since complete its inspection measure or line function, such surveyor's staff structure is simple, take light, easy to operate, but the precision of the level of measurement is relatively low, in measuring process, often judge whether level according to naked eyes, therefore precision is affected.
Summary of the invention
For the problems referred to above; technical problem to be solved in the utility model is to provide a kind of slide level bar; these slide level bar two ends are provided with port protection cover, and slide level bar two ends can be avoided in use to damage, and people also can be avoided in use injured.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of slide level bar, comprise chi body, vernier, air level and circular hole, described chi body is provided with vernier, air level and circular hole, dovetail groove is provided with bottom described chi body, its design feature is, described slide level bar also comprises port protection cover, described port protection cover comprises port protection cover one and port protection cover two, it is separately positioned on chi body two ends, and it is chimeric with the dovetail groove on chi body, described port protection cover one and port protection cover two are respectively equipped with three fixture blocks, groove is provided with between fixture block.
Preferably; middle fixture block on described port protection cover one is longer than other two fixture blocks; and a circular hole is provided with on middle fixture block, this circular hole is corresponding with the circular hole on chi body, and middle fixture block is also provided with the large draw-in groove can placing pencil and the little draw-in groove can placing draw point.
Preferably, three fixture block length on described port protection cover two are equal.
Compared with prior art; the utility model is provided with port protection cover at the two ends of slide level bar, and it can avoid slide level bar two ends to be damaged, thus extends the service time of surveyor's staff; in use, the hand of user can be avoided to be subject to the scratch at slide level bar two ends simultaneously.In addition, draw point and pencil are also arranged on slide level bar by the utility model, and this slide level bar is easy to use simply.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model port protection overlaps a structural representation.
Fig. 3 is that the utility model port protection overlaps two structural representations.
Embodiment
By detailed the utility model patent technology contents, architectural feature, reached object and effect, below will exemplify embodiment and coordinate Figure of description to be described in detail.
Fig. 1 is the utility model structural representation, and as shown in Figure 1, the utility model slide level bar, comprises chi body 1, vernier 4, air level 5 and circular hole 6, chi body 1 is provided with vernier 4, air level 5 and circular hole 6, bottom chi body 1, is provided with dovetail groove; This slide level bar also comprises port protection cover; this port protection cover comprises port protection cover 1 and port protection cover 23; it is separately positioned on chi body 1 two ends; and it is chimeric with the dovetail groove on chi body 1; port protection cover 1 and port protection cover 23 are respectively equipped with three fixture blocks, and are provided with groove between fixture block.
Fig. 2 is that the port protection of the utility model overlaps a structural representation, Fig. 3 is that the port protection of the utility model patent overlaps two structural representations, as shown in Figures 2 and 3, middle fixture block 21 on the port protection cover 1 of the utility model is longer than other two fixture blocks, and a circular hole 24 is provided with on middle fixture block 21, this circular hole 24 is corresponding with the circular hole 6 on chi body 1, and middle fixture block 21 is also provided with the large draw-in groove 22 can placing pencil and the little draw-in groove 23 can placing draw point; And three fixture block length that port protection overlaps on 23 are equal.
Content is only the preferred embodiment of the utility model in sum, does not limit the protection domain of the utility model patent with this.All equivalence changes done according to the utility model patent and description with modify, within the scope all contained in the utility model patent.
