Description
Technical field
The utility model relates to the fixed point pressure gauge, is specially the manometric demarcation frame of a kind of fixed point.
Background technology
The fixed point pressure gauge is the specialized equipment for the sedimentation pressure of measuring the key foundation privileged sites such as railway, highway, buildings.The manometric demarcation frame of fixing a point is a kind of support that is used for measuring water colunm height, its the penstock height that need to measure is 1.6 meters, need to record fix a point this moment manometric stress and frequency with readout instrument 0.1 meter to 1.6 meters position, form a whole row certificate, compare with standard again, see the gap between the corresponding hydraulic pressure height.The manometric demarcation support body of existing fixed point is long-pending larger, operate constant, easily speed and the accuracy of impact measurement.
The utility model content
The technical matters that the utility model solves is to provide a kind of fixed point manometric demarcation frame, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
The manometric demarcation frame of fixing a point, comprise scale bar, screw rod and base, described screw rod is fixedly connected with described base by thread, have a square groove on the described base, described scale bar is fixed on the described base by the interference fit with described square groove, cover has liftable shaking the hand on the described screw rod, is connected with rotary handle on described the shaking the hand, and described shaking the hand is threaded connection with described screw rod.
In the utility model, have U-lag on described the shaking the hand, described U-lag can block water pipe head.
Beneficial effect
The utility model is simple in structure, and is easy to use, guaranteed speed and the accuracy of measuring.
Description of drawings
Fig. 1 is the manometric demarcation shelf structure figure of fixed point.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, manometric demarcation shelf structure figure fixes a point, the manometric demarcation frame of fixing a point, comprise scale bar 2, screw rod 3 and base 4, described screw rod 3 and described base 4 are fixedly connected with by screw thread, have a square groove on the described base 4, described scale bar 2 is fixed on the described base 4 by the interference fit with described square groove, cover has and liftablely shakes the hand 1 on the described screw rod 3, and described shaking the hand is connected with rotary handle on 1, and described shaking the hand 1 is threaded connection with described screw rod 3.
In the utility model, described shaking the hand has U-lag on 1, and described U-lag can block water pipe head.
In the utility model, shaking the hand is connected with screw flight, and U-lag can block water pipe head, realizes the lifting of water pipe by rotary handle.To scale should be arranged, after water pipe reached desired height, the scale bar side of pushing to shake the hand was affixed with U-lag one side of shaking the hand, and can read the height of water column on the scale bar 2.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model; the technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. the manometric demarcation frame of fixing a point, comprise scale bar, screw rod and base, described screw rod is fixedly connected with described base by thread, have a square groove on the described base, described scale bar is fixed on the described base by the interference fit with described square groove, it is characterized in that, cover has liftable shaking the hand on the described screw rod, be connected with rotary handle on described the shaking the hand, described shaking the hand is threaded connection with described screw rod.
2. the manometric demarcation frame of fixed point according to claim 1 is characterized in that, have U-lag on described the shaking the hand, described U-lag can block water pipe head.
