Abstract
The utility model discloses an anti-detachment structure for a water meter, solves the problem that the conventional detachable water meter doesn't have an anti-detachment structure and has potential safety hazards, and adopts technical scheme that the anti-detachment structure comprises mounting screw holes and screws, which are arranged on a water meter body; each screw comprises a screw cap and a screw rod and further comprises an anti-detachment sleeve and an anti-detachment cover plate; the lower segment of the anti-detachment sleeve is provided with a ring-shaped inner lug boss; the inside diameter of the ring-shaped inner lug boss is smaller than the outside diameter of the screw cap and greater than the outside diameter of the screw rod; the screw rod of the screw penetrates through the anti-detachment sleeve to be in threaded connection with the mounting screw hole; and the anti-detachment cover plate is positioned above the screw cap in the ring-shaped sleeve. The anti-detachment structure provided by the utility model is very simple, cannot damage the structure of the water meter, is convenient to mount and can prevent detachment effectively.
Description
Technical field
The utility model relates to a kind of Anti-dismounting structure, specifically a kind of Anti-dismounting structure of water meter.
Background technology
At present, in the water meter industry, product category is various, and wherein, a kind of detachable water meter in use, in case of parts damage, can be backed out the screw on water meter, thereby pull down water meter, is keeped in repair or change movement, and this has simplified the maintenance job of water meter; But, bring unsafe factor also to the use of water meter, there are certain customers to reduce to pay water rate, illegally the water meter removable section is taken off voluntarily, cause the normal use procedure of water meter can't realize function of measuring, thereby bring loss to water supply department, also caused the waste of water resource.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, and provides a kind of structure very simply, not destroy the preventing watermeter from being detached structure of water meter self structure, easy for installation, effective tamper.
Technical scheme comprises installation screw and the screw of being located on the water meter body, described screw comprises nut and screw rod, it is characterized in that, also include tamper sleeve pipe and tamper cover plate, described tamper sleeve pipe hypomere is established annular inner convex platform, the internal diameter of described annular inner convex platform is less than the nut external diameter and is greater than the external diameter of screw rod, and the screw rod of described screw is threaded with installation screw through the tamper sleeve pipe, and described tamper cover plate is positioned at the nut top of ring sleeve.
Described tamper cover plate coordinates with the tamper sleeve interference.
The utility model utilizes the annular inner convex platform in the tamper sleeve pipe to realize spacing to nut, at screw rod with when installation screw is threaded, prevent that nut from deviating from the tamper sleeve pipe, coordinate again the encapsulation of tamper cover plate, thereby the nut that makes originally to be exposed on the water meter body is encapsulated in the tamper sleeve pipe fully, realizes the purpose of tamper.The utility model structure is very simple, simple installation, and without water meter body self structure is improved, tamper is effective.Be not only applicable to the tamper of detachable watermeter (horizontal screw wing dismantling water meter), for utilizing screw and installation screw to be connected in other field and having the device of tamper requirement all applicable.
The accompanying drawing explanation
Fig. 1 is the utility model scheme of installation.
Fig. 2 is the utility model cut-open view.
Wherein, 1-water meter body, 2-installation screw, 3-screw, 3.1-nut, 3.2-screw rod, 4-tamper sleeve pipe, 4.1-annular inner convex platform, 5-tamper cover plate.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further explained to explanation:
Referring to Fig. 2, it is that hexagon socket head cap screw or other do not affect the screw that screw is tightened in the interior rotation of tamper sleeve pipe 4 that water meter body 1 is provided with installation screw 2 and screw 3(), described screw 3 comprises nut 3.1 and screw rod 3.2, also include tamper sleeve pipe 4 and tamper cover plate 5, described tamper sleeve pipe 4 hypomeres are established annular inner convex platform 4.1, the internal diameter of described annular inner convex platform 4.1 is less than nut 3.1 external diameters and is greater than the external diameter of screw rod 3.2, and the screw rod 3.2 of described screw 3 is threaded with installation screw 2 through tamper sleeve pipe 4.When screw 3 is inserted in tamper sleeve pipe 4, screw rod 3.2 can pass tamper sleeve pipe 4 like this, and nut 3.1 can be limited in tamper sleeve pipe 4, and described tamper cover plate 5 is positioned at nut 3.1 tops of ring sleeve 4, and with tamper sleeve pipe 4 interference fit.
Referring to Fig. 1, during installation, first by screw 3, be inserted in tamper sleeve pipe 4 and screw rod 3.2 is stretched out, then in the installation screw 2 screw rod 3.2 inserted on water meter body 1 and with opener, screw 3 and installation screw 2 are tightened to (being threaded engagement), annular inner convex platform 4.1 on tamper sleeve pipe 4 is also compressed by nut 3.1, then the 5 use external force pressurizations of tamper cover plate are squeezed in tamper sleeve pipe 4, tamper cover plate 5 is sealed the opening of tamper sleeve pipe 4 upper ends.The utility model Anti-dismounting structure only can disposablely be used, once can't dismantle after installing, if think, pulls down by force, essential this this structure of destroying.Management company (as Running-water Company), once find that said structure is destroyed, can judge that water meter was artificially dismantled.
In addition, on same water meter body 1, a set of Anti-dismounting structure can only be installed, or, according to many cover Anti-dismounting structures are installed, be not construed as limiting here.
Claims (2)
1. the Anti-dismounting structure of a water meter, comprise installation screw and the screw be located on the water meter body, described screw comprises nut and screw rod, it is characterized in that, also include tamper sleeve pipe and tamper cover plate, described tamper sleeve pipe hypomere is established annular inner convex platform, and the internal diameter of described annular inner convex platform is less than the nut external diameter and is greater than the external diameter of screw rod, the screw rod of described screw is threaded with installation screw through the tamper sleeve pipe, and described tamper cover plate is positioned at the nut top of ring sleeve.
2. the Anti-dismounting structure of water meter as claimed in claim 1, is characterized in that, described tamper cover plate coordinates with the tamper sleeve interference.
